The present invention relates to a sperm collecting apparatus, and more particularly, to a sperm collecting apparatus which is improved in the past in accordance with social needs such as medical research, medical treatment, crime prevention, sale prevention, and venereal disease propagation.

Background

In accordance with medical research and therapeutic needs, various sperm collecting devices (ejaculation stimulating devices) for collecting sperm have been proposed.

Sperm collecting devices are used in medical needs, such as checking sexual function of husband or treating sexual dysfunction based on collected sperm in order to find out the cause of infertility between couples, and retaining and keeping sperm for artificial insemination. In addition, sperm collecting apparatuses have been used to meet various social needs, such as prevention of sexual crimes, prevention of malting, reduction of the number of sexually transmitted diseases, and the like, by solving individual sexual desire.

The sperm collecting apparatus is a unit which has an insertion space into which a penis is inserted, and stimulates the tip of the penis by friction generated as the penis moves forward and backward in the insertion space, thereby promoting ejaculation.

For example, patent document 1 discloses an ejaculation stimulating device including: a cylindrical container made of a hard plastic material, having an open base end in the longitudinal direction and an air hole at the tip end; and a gel-like resin core member which is housed in the container and has an insertion space extending from the insertion opening at the base end in the longitudinal direction to the inside.

In the ejaculation stimulating device of patent document 1, the penis inserted into the insertion opening is advanced and retreated in the insertion space, thereby stimulating the tip of the penis to stimulate ejaculation. In addition, in this ejaculation stimulating device, the pressure reducing device is attached to the distal end side of the container, and the interior of the container is reduced in pressure through the air hole, thereby giving strong stimulation to the penis.

Further, patent document 2 discloses a masturbation apparatus for both men and women, which includes: an inner body made of elastic resin, the base end of which in the longitudinal direction is provided with an insertion opening for a penis, and the inner body is provided with an insertion space connected with the insertion opening; a container having a bottle shape with a base end opened in a longitudinal direction and a tip closed, and accommodating the inner body; and an air volume adjusting ring provided to be rotatable with respect to an outer peripheral surface of the container near the base end. The masturbation device of patent document 2 is also configured to stimulate the tip of the penis by moving the penis inserted from the insertion opening back and forth in the insertion space.

In the masturbation device of patent document 2, a container side opening is provided on a side surface of the container near the base end in the longitudinal direction, a ring side opening is provided on the air volume adjusting ring, and the area of the overlapping portion of the container side opening and the ring side opening is changed in accordance with the amount of rotation of the air volume adjusting ring.

Detailed Description

< overview and characteristics of sperm collecting apparatus 1 >

Embodiments of the present invention will be described below with reference to the drawings.

First, the outline and characteristics of the sperm collecting apparatus 1 will be explained. Fig. 1(a) is a sectional view of the sperm collecting apparatus 1, fig. 1(b) is a sectional view illustrating an insertion space ES inside the core 10, and fig. 2 is a drawing illustrating a use state of the sperm collecting apparatus 1.

The sperm collection apparatus 1 shown in fig. 1(a) and 1(b) includes: a core member 10 made of a cylindrical elastic material and provided with an insertion space ES in which a penis P (see fig. 2) inserted into the insertion opening 11a can relatively move, and a container 20; the container 20 has an inner space IS for receiving the core 10.

The core member 10 is made of an elastic material such as an elastomer or a gel resin, and changes its volume as the penis P moves forward and backward in the insertion space ES. For example, when the penis P moves from the proximal end side to the inner depth direction in the insertion space ES, the core member 10 expands, and when the penis P moves from the inner depth side to the proximal end direction in the insertion space ES, the core member 10 contracts.

The container 20 includes: a base unit 30 made of a hard plastic material (hard resin material), configured in a cylindrical shape with both ends open in the axial direction, and having an end portion on the insertion port 11a side of the core 10 attached to an opening portion on the base end side (one end side); and a movable unit 40 made of a hard plastic material, configured in a cup shape (cylindrical shape) having an axial base end (one end) open and a tip end (the other end) closed, and assembled to be rotatable about an axial center with respect to the base unit 30 without coming off. The base unit 30 fixedly or detachably supports the vicinity of an end portion (base end portion) on the insertion port 11a side of the core component 10.

At the axial intermediate position P1 of the sperm collecting device 1, the base end inner peripheral surface of the movable unit 40 and the distal end outer peripheral surface of the base unit 30 are superposed, and an air flow path AP through which air flows inside and outside the container 20 and an adjustment mechanism AD for adjusting the air flow rate of the air flow path AP are provided at the superposed part where the two peripheral surfaces face each other. The adjustment mechanism AD adjusts the air flow rate of the air flow path AP according to the rotation angle of the movable unit 40 with respect to the base unit 30.

As shown in fig. 2, during use of the sperm collecting apparatus 1, the penis P (tip PT) relatively reciprocates in the axial direction within the insertion space ES. Since the penis P is in contact with the inner peripheral surface of the core member 10, a stimulus is given by friction (sliding friction) accompanying its movement in the insertion space ES, promoting ejaculation.

During use of the sperm collecting apparatus 1, a viscous liquid lubricant is applied to the insertion space ES as needed, and a contraceptive device (condom, not shown) is attached to the penis P of the user. In this case, the user's semen is ejected into the contraceptive and collected. In addition, when the lubricant is not used, the semen ejected into the insertion space ES may also be collected.

By relatively moving the tip PT of the penis P from the proximal end side to the inner deep side in the insertion space ES, the core member 10 is inflated to the outer peripheral side by the penis P in the insertion space ES as indicated by the broken line denoted by the reference numeral "EX". As a result, the air in the inner space IS of the container 20 IS discharged to the outside of the container 20 through the adjustment mechanism AD and the air flow path AP.

When the tip PT of the penis P moves relatively from the deep inside toward the proximal end side in the insertion space ES, the inside of the insertion space ES is depressurized. Accompanying the decompression in the insertion space ES, the core member 10 contracts as indicated by the broken line labeled "CT".

As a result, the close contact force between the tip PT of the penis P and the inner peripheral surface of the core member 10 is increased, and the stimulation applied to the tip PT of the penis P is increased. In addition, along with the contraction of the core member 10, the air outside the container 20 flows into the inner space IS of the container 20 through the air flow path AP and the adjustment mechanism AD.

As shown in fig. 1(a), the adjustment mechanism AD has a structure in which the area of the overlapping portion of the rubber ring side opening 34c (second opening) of the base unit 30 (second rubber ring 34) and the bending piece side opening 42e (first opening) on the movable unit 40 side is freely changed. For example, in the adjustment mechanism AD of the first embodiment, the number of the rubber ring side openings 34c (small holes) arranged in the bending piece side opening 42e is changed, so that the area of the overlapping portion of the rubber ring side opening 34c and the bending piece side opening 42e is changed, and the air flow rate (air flowability) in the adjustment mechanism AD is adjusted.

The stimulation applied to the tip PT of the penis P is changed according to the air flow rate adjusted by the adjustment mechanism AD. The adjustment of the air flow rate by the adjustment mechanism AD will be described in detail later.

As shown in fig. 2, when the air flow rate in the adjustment mechanism AD IS small (when the air IS hard to flow), if the penis P (distal end PT) moves relatively from the proximal end side to the inner deep side in the insertion space ES, the core 10 expands and the air IS discharged from the insertion space ES to the inner space IS of the container 20, and the air IS difficult to be discharged from the inner space IS of the container 20 to the outside of the container 20, so that the expansion of the core 10 becomes difficult and the stimulation of the penis P by the protrusion 11e becomes strong.

Similarly, if the air flow rate in the adjustment mechanism AD IS small, if the penis P moves relatively from the inner deep side to the proximal side in the insertion space ES, the air flow from the container 20 to the inner space IS becomes difficult, the contraction of the core member 10 becomes difficult, the close contact force between the tip PT of the penis P and the inner peripheral surface of the core member 10 becomes high, and the stimulation of the penis P by the projection 11e becomes strong.

On the contrary, when the air flow rate in the adjustment mechanism AD IS large (when the air flows easily), if the penis P moves relatively from the proximal end side to the inner depth side in the insertion space ES, the air flows smoothly from the inner space IS to the outside of the container 20, and therefore, the core member 10 IS more likely to be inflated than when the air flow rate IS small. As a result, the penis P is less stimulated by the projection 11e than when the air flow rate is small.

Similarly, when the air flow rate in the adjustment mechanism AD IS large, if the penis P moves relatively from the deep inside side to the proximal side in the insertion space ES, air smoothly flows out of the container 20 into the inner space IS, and therefore, compared to the case where the air flow rate IS small, contraction of the core member 10 becomes easy, and the close contact force between the penis P and the inner circumferential surface of the core member 10 becomes low. As a result, the penis P is less stimulated by the projection 11e than when the air flow rate is small.

Therefore, the stimulation applied to the tip PT of the penis P becomes larger when the air flow rate in the adjustment mechanism AD is small than when the air flow rate is large, and ejaculation is promoted.

As will be described later, the flow rate of air flowing inside and outside the container 20 (air resistance of the adjustment mechanism AD) is adjusted according to the rotation angle of the movable unit 40 with respect to the base unit 30. The adjustment mechanism AD is provided separately on the base unit 30 side and the movable unit 40 side, and communicates with the outside of the container 20 through an air flow path AP provided along the boundary between the base end inner peripheral surface of the movable unit 40 and the distal end outer peripheral surface of the base unit 30.

In the sperm collecting apparatus 1, since the air flow path AP and the adjustment mechanism AD are provided at the overlapping portion where the base end (one end) of the movable unit 40 and the tip end (the other end) of the base unit 30 face each other, it is difficult for the user to block the air flow path AP with the fingers during use, and it is possible to suppress the change of stimulus other than that intended by the user.

< details of the sperm collecting apparatus 1 of the first embodiment >

Next, details of the sperm collecting device 1 according to the first embodiment will be explained. First, the core member 10 will be explained. Fig. 3(a) is a diagram illustrating the core member 10, and fig. 3(b) is a diagram illustrating the ring member.

< core component 10 >

The sperm collecting apparatus 1 shown in fig. 2 includes a core member 10, and the core member 10 is in close contact with a tip PT of a penis P reciprocating in the longitudinal direction in an insertion space ES to stimulate the penis P.

As shown in fig. 3(a), the core member 10 includes: a core body 11 made of an elastic material (elastomer, gel-like resin, etc.) that simulates the softness of a human body (inside the vagina); and a plurality of (e.g., 3) ring members 12 made of an elastic material (elastomer, gel-like resin, etc.) harder than the core main body 11 and enclosed in the core main body 11.

The core body 11 includes: a disk-shaped flange portion 11b having an insertion opening 11a provided at the center of the end surface thereof; a cylindrical portion 11c having an insertion space ES provided therein; and a plurality of ring-receiving portions 11d (for example, 3) provided at intervals at portions of the cylindrical portion 11c close to the flange portion 11 b.

The flange portion 11b is fixed to or detachably attached to the base end 30a of the base unit 30 (the base end 31a of the first cylindrical member 31) of the container 20 in an airtight state.

The tubular portion 11c is a bag body whose distal end side is closed, and has an insertion space ES provided therein and communicating with the insertion port 11 a. The cylindrical portion 11c has a plurality of protrusions 11e on its inner peripheral surface, and has a concave-convex shape. The tip PT of the penis P is closely contacted with the inner peripheral surface of the cylindrical portion 11c in the insertion space ES. Therefore, when the tip PT of the penis P moves forward and backward in the insertion space ES, the tip PT is stimulated by the projection 11e to promote ejaculation.

The ring housing 11d houses the ring member 12 shown in fig. 3 (b). The ring member 12 has: an annular outer peripheral portion 12 a; a disk-shaped inner peripheral portion 12c having an opening 12b formed at the center thereof for inserting the penis P; and a plurality of spokes 12d connecting the outer peripheral portion 12a and the inner peripheral portion 12c at intervals in the circumferential direction.

The opening 12b forms a part of the insertion space ES (see fig. 1 b). The inner peripheral portion 12c is provided with a plurality of protrusions 12e curved in a spiral shape toward the opening portion 12 b. These ribs 12e generate a circumferential rotational force by friction with the penis P during the forward and backward movement of the penis P. The spoke portions 12d are bent in the circumferential direction by the rotational force, so that the inner circumferential portion 12c is rotated to stimulate the penis P.

< container 20 >

Next, the container 20 will be explained. Fig. 4 is a front view of the container 20, fig. 5 is an exploded perspective view of the container 20, and fig. 6 is a sectional view of the container 20.

As shown in fig. 4 to 6, the container 20 includes: a tubular base unit 30 configured in a tubular shape with both ends open in the axial direction; a movable unit 40 which is configured into a cup shape (cylindrical shape) having an open proximal end in the axial direction and a closed distal end, and which is assembled to be rotatable about the axial center with respect to the distal end of the base unit 30 without coming off; and a cap CP attached to the base end of the base unit 30 so as to be detachable.

< matrix unit 30 >

As shown in fig. 5, the base unit 30 includes: a first cylindrical member 31 having two open ends; a second tubular member 32 which is a tubular member having both ends open and which has a substantially V-shaped recess (V groove) 32a formed along the entire circumference in the middle of the axial direction thereof; a first rubber ring 33 sandwiched between the front end of the first cylinder member 31 and the base end of the second cylinder member 32; and a second rubber ring 34 attached to the front end of the second cylinder member 32. Further, by providing the recess 32a, the user's fingertip is easily caught in the recess 32a, and the problem that the sperm collecting device 1 falls off from the user's hand is suppressed.

As shown in fig. 1, the flange portion 11b of the core member 10 is fixed to or detachably attached to the base end 31a of the first tubular member 31 in an airtight state along the entire circumference. The proximal end portion of the core member 10 slightly protrudes outward in the axial direction (toward the user during use) from the proximal end of the container 20.

As shown in fig. 6, the half tip side of the first cylindrical member 31 and the half base end side (the portion of the base end side from the recess 32 a) of the second cylindrical member 32 are fitted to each other, and the outer peripheral surface of the half base end side of the second cylindrical member 32 is fitted in close contact with the inner peripheral surface of the half tip side of the first cylindrical member 31.

As shown in fig. 5, the first rubber ring 33 includes: an elongated cylindrical tube portion 33 a; and an annular flange portion 33b provided to protrude laterally from the distal end of the tube portion 33 a. As shown in fig. 6, the cylindrical portion 33a of the first rubber ring 33 is in close contact with the inner circumferential surface of the first cylindrical member 31, and the flange portion 33b is sandwiched between the first cylindrical member 31 and the second cylindrical member 32. The first cylinder member 31 and the second cylinder member 32 are connected in an airtight state by sandwiching the first rubber ring 33.

In the sperm collecting device 1 of the first embodiment, the first tubular member 31 and the second tubular member 32 are each made of a hard plastic material (for example, the first tubular member 31 is made of a polycarbonate resin, and the second tubular member 32 is made of an ABS resin), and the first rubber ring 33 is made of a synthetic resin having flexibility and sealing property (various rubber materials or an elastomer having rubber elasticity).

As shown in fig. 5, a base-side opening 32c that is elongated and has a length smaller than the entire circumference is provided in the circumferential direction on the side surface (outer circumferential surface) of the distal end portion 32b of the second tubular member 32. As will be described later, the base-side opening 32c IS fitted with a projection 34b having the second rubber ring 34, and the inner space IS of the container 20 and the air flow path AP are communicated with each other via a rubber-ring-side opening 34c (small hole, second opening) provided in the projection 34b (see fig. 6).

As shown in fig. 4 and 5, a base side mark 32d is formed on the surface of the V-shaped recess 32a in the second tubular member 32 over a circumferential range corresponding to the base side opening 32 c. A plurality of grooves (recesses) having different lengths are provided in the base side mark 32d at intervals in the circumferential direction. The length of the base side mark 32d (the length of the groove) indicates the air flow rate adjusted by the adjustment mechanism AD. For example, the shortest left base side mark 32d indicates the state of the smallest air flow rate, and the longest right base side mark 32d indicates the state of the largest air flow rate. The base side marks 32d (grooves) are extended to the base side opening portions 32c, and the insides of the grooves become a part of the air flow path AP.

Further, the air flow path AP may be provided between the outer peripheral surface of the base unit 30 and the inner peripheral surface of the movable unit 40, and therefore a groove that becomes a part of the air flow path AP may be provided on the base end inner peripheral surface of the movable unit 40 (the cup member 41).

As shown in fig. 5 and 6, a locking groove 32e extending in the circumferential direction is provided at the distal end edge (the boundary with the base-side opening portion 32 c) of the V-shaped recess 32a in the second tubular member 32. The movable unit 40 is locked by the locking groove 32e so as to be rotatable about the axial center with respect to the base unit 30 and so as not to fall off (as will be described later).

Further, one of the second cylindrical member 32 and the movable ring 42 may be made of a hard plastic material having elastic properties, and the other may be made of a hard plastic material having no elastic properties, and the second cylindrical member 32 and the movable ring 42 may be provided with an engagement structure formed by a combination of a protrusion and a recess. As shown in fig. 5, an elastic piece 32f having elasticity and having a projection formed on the inner peripheral side is provided at the front end of the second tubular member 32. The protrusion of the elastic piece 32f is engaged with the engagement recess 42d of the movable unit 40. Therefore, in the example of fig. 5, the elastic piece 32f and the engagement recess 42d constitute an engagement structure.

A plurality of protruding pieces 32g are provided at intervals in the circumferential direction on the front end peripheral edge of the second cylindrical member 32. As shown in fig. 8, the distal end of each protruding piece 32g comes into contact with the flange 42a from the proximal end side in the axial direction, and supports the movable ring 42.

As shown in fig. 5 and 6, the second rubber ring 34 includes an elongated cylindrical tube portion 34a, and the tube portion 34a is in close contact with the inner peripheral surface of the distal end portion 32b of the second tubular member 32. The portion (portion within the opening range) corresponding to the base-side opening portion 32c in the second rubber ring 34 has a larger thickness than the other portions, and is formed with an elongated protruding strip portion 34b in the circumferential direction. The protruding portion 34b is provided with a bead-side opening portion 34c, and the protruding portion 34b is fitted into the base-body-side opening portion 32 c.

The rubber ring side opening 34c is, for example, a circular small hole, and is formed in a plurality at intervals in the circumferential direction. As shown in fig. 5, in the first embodiment, 9 rubber ring side openings 34c are provided, and the 1 st to 7 th rubber ring side openings 34c have the same shape (the same opening area) from the left end. The 8 th and 9 th rubber ring side openings 34c have the same shape (the same opening area) from the left end and are larger than the 1 st to 7 th rubber ring side openings 34 c.

Each of the rubber ring side openings 34c may be formed by a plurality of circular small holes having the same size, or may be formed by small holes having a shape other than a circular shape such as a square shape.

In the sperm collecting device 1 of the first embodiment, the second rubber ring 34 is made of a synthetic resin (for example, various rubber materials or an elastic body having rubber elasticity) having the same flexibility and sealing property as those of the first rubber ring 33.

< Movable Unit 40 >

Next, the movable unit 40 will be explained. Fig. 7 is a perspective view of the cup member 41 as viewed from the opening portion side (proximal end side), and fig. 8 is a perspective view illustrating a state in which the movable ring 42 is attached to the base unit 30.

As shown in fig. 5, the movable unit 40 includes: a cup-shaped cup member 41 having a base end (one end) opened and a tip end (the other end) closed, and having a tip end smaller in diameter than the base end; and a movable ring 42 attached to an inner peripheral surface of the cup member 41 on the proximal end opening side and rotating integrally with the cup member 41. In the present embodiment, the cup member 41 is made of a hard plastic material (e.g., polycarbonate resin). Further, by forming the cup member 41 of a different kind of resin material from the second cylindrical member 32, it is possible to suppress generation of abnormal noise due to sliding friction and smoothly slide the cup member 41 and the second cylindrical member 32.

As shown in fig. 4, a movable-side mark 41a is provided on the base-end outer peripheral surface of the cup member 41. The movable-side mark 41a is formed of a protrusion, and the position of one of the plurality of base-side marks 32d in the circumferential direction is matched according to the rotation angle of the movable unit 40 with respect to the base unit 30. The movable-side indicator 41a may be formed by printing or sticking.

As described above, the length of the base side mark 32d (the length of the groove) indicates the air flow rate (air resistance) in the adjustment mechanism AD. Therefore, the user can recognize the air flow rate based on the length of the base side mark 32d indicated by the movable side mark 41 a.

As shown in fig. 7, a first locking protrusion 41b extending in the circumferential direction is provided on the base end inner peripheral surface of the cup member 41. As shown in fig. 6, the first locking projection 41b is locked to a locking groove 32e provided in the second tubular member 32 and is movable in the circumferential direction in the locking groove 32 e. Therefore, in a state where the movable unit 40 is attached to the base unit 30, the cup member 41 (movable unit 40) is assembled to be rotatable about the axial center with respect to the second cylindrical member 32 (base unit 30) and not to be detached.

As shown in fig. 7, a plurality of elongated second locking projections 41c extending in the axial direction (longitudinal direction) of the cup member 41 are provided on the inner peripheral surface of the cup member 41. In the example of fig. 7, 3 second locking projections 41c are provided at intervals of about 90 degrees in the circumferential direction. The lower end of each second locking projection 41c is fitted into a locking groove 42c (fig. 8) provided in the movable ring 42. Thereby, the movable ring 42 rotates around the axial center together with the cup member 41.

As shown in fig. 5 and 8, the movable ring 42 includes: an annular flange portion 42a that abuts against the distal end (second rubber ring 34) of the base unit 30; and a bent piece 42b integrated with the flange portion 42 a. The movable ring 42 is made of a hard plastic material (e.g., polyacetal resin, polyamide resin) having elastic properties.

The flange portion 42a is provided with: a notch-shaped locking groove 42c into which the base end of a second locking protrusion 41c provided on the inner peripheral surface of the cup member 41 is fitted; and a notch-shaped engagement recess 42d for engaging with the elastic piece 32f (projection) provided on the second tubular member 32. In the illustrated example, the locking grooves 42c are provided at 3 intervals in the circumferential direction, and the same number of engaging recesses 42d as the base side marks 32d are provided at the same intervals in the circumferential direction, similarly to the second locking projections 41 c.

As described above, when the base end of each second locking protrusion 41c is fitted in the corresponding locking groove 42c, the movable ring 42 rotates around the axial center together with the cup member 41. Further, when the engagement and disengagement are repeated between the projections of the elastic piece 32f and the respective engagement recesses 42d during the rotation of the movable unit 40, the strength of the rotation resistance changes (knocking feeling).

By this knocking feeling, the user can recognize by the tactile sensation that the movable unit 140 is rotated to change the amount of air during the use of the sperm collecting device 1. Further, it is possible to suppress the problem that the movable unit 140 is rotated against the user's will.

The bent piece 42b is a plate-like member elongated in the circumferential direction, and is bent in accordance with the front end inner peripheral surface of the base unit 30 (the inner peripheral surface of the second rubber ring 34). When the movable unit 40 (the cup member 41) rotates about the axial center, the bent pieces 42b move in the circumferential direction along the front end inner peripheral surface of the base unit 30.

The bent piece 42b is provided with a bent piece side opening 42e (first opening) elongated in the circumferential direction. The bending piece side opening 42e is provided in a shape capable of disposing the plurality of rubber ring side openings 34c (the plurality of second openings) provided in the second rubber ring 34 within the opening range.

As shown in fig. 6, in a state where the movable unit 40 is attached to the base unit 30, the base end inner peripheral surface of the cup member 41 coincides with the base end outer peripheral surface of the second cylindrical member 32. The overlapping portions of the bent pieces 42b facing the second cylindrical member 32 sandwich the second rubber ring 34, and are attached in an airtight state except for the rubber ring side opening 34 c.

Further, an air flow path AP is formed between the base end inner peripheral surface of the cup member 41 and the base end outer peripheral surface of the second cylindrical member 32 by the base side mark 32 d. Thereby, the inner space IS of the container 20 and the outside of the container 20 are communicated with each other through the rubber ring side opening 34c (adjustment mechanism AD) and the air flow path AP.

< adjustment mechanism AD >

The adjustment mechanism AD adjusts the flow rate of air (air flowability) flowing through the inside and outside of the container 20. In the sperm collecting apparatus 1 according to the first embodiment, the adjustment mechanism AD is constituted by the distal end portion of the base unit 30 (the distal end portion 32b of the second tubular member 32, the rubber ring side opening 34c) and the proximal end portion of the movable unit 40 (the movable ring 42, the bending piece side opening 42 e).

Next, the adjustment mechanism AD will be explained. Fig. 9(a) is a partially enlarged cross-sectional view of the vicinity of the adjustment mechanism AD, fig. 9(b) is a view explaining the air flow in the vicinity of the adjustment mechanism AD, fig. 10 is a view explaining the rotating operation of the movable unit 40, fig. 11(a) is a view explaining the positional relationship between the bending piece-side opening 42e and the rubber ring-side opening 34c when the air flow rate is minimized by the adjustment mechanism AD, and fig. 11(b) is a view explaining the positional relationship between the bending piece-side opening 42e and the rubber ring-side opening 34c when the air flow rate is maximized by the adjustment mechanism AD.

As shown in fig. 9(a), when the bending piece side opening portion 42e IS moved in the circumferential direction and the plurality of rubber ring side opening portions 34c are positioned within the opening range of the bending piece side opening portion 42e, the inside space IS of the container 20 and the outside of the container 20 communicate with each other through the air flow path AP, the rubber ring side opening portion 34c, and the bending piece side opening portion 42e as shown by an arrow "AF" in fig. 9 (b). At this time, the flow rate of air flowing in and out of the container 20 is determined by the total opening area of the rubber ring side openings 34c arranged in the opening range of the bending piece side opening 42e, that is, the number of the rubber ring side openings 34c (the number of small holes).

As shown in fig. 10, the flow rate of air flowing in and out of the container 20 can be adjusted by rotating the movable unit 40 about the axial center with respect to the base unit 30. That is, the bending piece 42b is moved in the circumferential direction in accordance with the rotation of the movable unit 40, and the relative position in the circumferential direction between the bending piece side opening 42e and the rubber ring side opening 34c can be changed.

For example, in the state shown in fig. 11(a), since the rubber ring side opening 34c is not located within the opening range of the bending piece side opening 42e, air is most difficult to flow. On the other hand, in the state shown in fig. 11(b), since each of the plurality of rubber ring side openings 34c is located within the opening range of the bending piece side opening 42e, air flows most easily.

Then, in the intermediate state between the state shown in fig. 11(a) and the state shown in fig. 11(b), the air flow rate is changed in accordance with the total sum of the opening areas (the number of small holes) of the rubber ring side openings 34c located within the opening range of the bending piece side opening 42 e.

< summary of the first embodiment >

In the sperm collecting apparatus 1 of the first embodiment, the overlapping portion (facing portion) of the inner peripheral surface of the proximal end side portion of the movable unit 40 and the outer peripheral surface of the distal end side portion of the base unit 30 has the air flow path AP, and the adjustment mechanism AD for adjusting the air flow rate flowing inside and outside the container 20 IS provided between the air flow path AP and the inner space IS of the container 20, and the air flow rate can be adjusted in accordance with the rotation angle of the movable unit 40 with respect to the base unit 30.

< sperm collecting device 1A > of the second embodiment

In the sperm collecting device 1 of the first embodiment described above, the stimulation to the tip PT of the penis P is adjusted by changing the air resistance of the adjustment mechanism AD in accordance with the total opening area of the rubber ring side openings 34c (the number of rubber ring side openings 34c) located within the opening range of the bending piece side opening 42e, but the present invention is not limited to this configuration.

For example, as shown in fig. 12, the rubber ring side opening 134c (second opening) and the base side opening 132c (second opening) may be formed by a plurality of types of openings having different opening areas, and any one of the plurality of sets of the rubber ring side opening 134c and the base side opening 132c may be positioned inside the movable cylinder side opening 142g (first opening) in accordance with the rotation angle of the movable unit 140 with respect to the base unit 130.

The sperm collecting device 1A of the second embodiment configured as described above will be explained below. Fig. 12 is an exploded perspective view illustrating a main part of a sperm collecting device 1A according to the second embodiment, fig. 13(a) is a view illustrating a state in which one of a plurality of the rubber ring side openings 134c is selected, and fig. 13(b) is a view illustrating a state in which the rubber ring side opening 134c is not selected.

The sperm cell collection device 1A shown in fig. 12 includes: a plurality of base-side openings 132c (second openings) provided in the side surface of the distal end 132b of the base unit 130 (second tubular member 132); a plurality of rubber ring side opening portions 134c (second opening portions) provided in the second rubber ring 134; and a movable cylinder side opening 142g (first opening) provided in the movable ring 142.

In the sperm collecting device 1A, the same components as those of the sperm collecting device 1 according to the first embodiment are given the same reference numerals, and the description thereof will be omitted. The configuration not shown is the same as that of the sperm collecting apparatus 1 according to the first embodiment, and therefore, the description thereof will be omitted.

The base unit 130 includes a first tubular member 131, a second tubular member 132, a first rubber ring (not shown), and a second rubber ring 134, as in the base unit 30 of the first embodiment. The first tube member 131 and the first rubber ring have the same structure as the first tube member 31 and the first rubber ring 33 of the first embodiment, and therefore, the description thereof is omitted.

The second tubular member 132 is a tubular member having both ends open in the axial direction, and is provided with a V-shaped recess 132a along the entire circumference in the axial direction. A portion closer to the base end side than the recess 132a in the second cylindrical member 132 is fitted to the inner circumferential side of the half tip end side of the first cylindrical member 131. Similarly to the first rubber ring 33 of the first embodiment, the first rubber ring is sandwiched between the second cylindrical member 132 and the first cylindrical member 131, and the cylindrical members 131 and 132 are connected in an airtight state.

A plurality of base-side openings 132c are formed at circumferentially spaced intervals in the side surface of the distal end 132b of the second tubular member 132. In the illustrated example, the base-side opening portions 132c are formed by circular small holes, and 9 are formed at intervals in the circumferential direction. The base-side openings 132c have different opening areas, and the base-side opening 132c (1) located at the left end in the drawing has the largest opening area, and the base-side opening 132c (9) located at the right end has the smallest opening area.

An engagement recess 132d formed of a plurality of grooves (recesses) is provided on the inner peripheral surface of the distal end 132b of the second tubular member 132 at a position on the opposite side in the circumferential direction from the base-side opening 132 c. Further, a plurality of protrusions 132e that are non-return features of the second rubber ring 134 are formed at circumferentially spaced intervals at the front end 132b of the second tubular member 132. In the illustrated example, 4 projections 132e are formed at intervals of 90 degrees.

The second rubber ring 134 includes an annular portion 134a, a bent piece 134b that is integrated with the annular portion 134a and is elongated in the circumferential direction, and a rubber ring side opening 134c provided in the bent piece 134 b. Like the second rubber ring 34 of the first embodiment, the second rubber ring 134 of the second embodiment is also made of a synthetic resin having flexibility and sealability (for example, various rubber materials or an elastomer having rubber elasticity).

The annular portion 134a is a portion placed on the distal end surface of the second cylindrical member 132, and notches 134d that fit with projections 132e provided on the distal end of the second cylindrical member 132 are formed at 90-degree intervals in the circumferential direction. The bent piece 134b is bent in conformity with the front end inner peripheral surface of the second cylindrical member 132, and is provided in a shape (for example, a long rectangle) capable of covering all the base body side opening 132 c.

As with the base-side opening 132c, a plurality of rubber-ring-side openings 134c are formed at intervals in the circumferential direction. In the illustrated example, each of the rubber ring side openings 134c is formed of 9 circular small holes having different areas, and the rubber ring side opening 134c (1) located at the left end has the largest area and the rubber ring side opening 134c (9) located at the right end has the smallest area. In the present embodiment, the shape (opening area) and the formation position of each rubber ring side opening 134c and each corresponding base body side opening 132c are matched with each other.

Further, a substantially quadrangular rib 134e that individually surrounds each rubber-ring-side opening 134c is formed on the inner peripheral surface of the bent piece 134 b. Further, the rubber ring side opening 134c is not provided on the inner periphery of the rib 134e positioned on the right end.

The movable ring 142 includes: an annular flange portion 142a that abuts the distal end (second rubber ring 134) of the base unit 130; and a movable cylinder 142b provided on the flange portion 142 a. The flange portion 142a is provided with a notch-shaped locking groove 142c into which the base end of a second locking protrusion 41c provided on the inner peripheral surface of the cup member 41 is fitted. Thus, the movable ring 142 rotates about the shaft center together with the cup member 41.

The movable tube 142b is provided with a movable tube side opening 142g (first opening). The movable cylinder side opening 142g is a single rectangular opening, and one of the plurality of rubber ring side openings 134c can be individually arranged inside the opening.

An engagement projection 142d is formed at a position rotated 180 degrees in the circumferential direction from the position of the movable tube side opening 142g in the movable tube 142 b. The engaging projection 142d projects outward at a circumferential central portion of the plate spring portion 142e elongated in the circumferential direction. In the present embodiment, the leaf spring portion 142e is provided by 2 slits 142f formed at intervals in the axial direction and elongated in the circumferential direction.

When any one of the plurality of rubber ring side openings 134c is disposed inside the movable cylinder side opening 142g, the engaging projection 142d engages with one of the plurality of engaging recesses 132d provided on the front end inner peripheral surface of the second cylinder member 132. When the engaging projection 142d engaged with the engaging recess 132d moves toward the adjacent engaging recess 132d, the rotation resistance of the movable unit 140 changes (knocking feeling).

The user can recognize the rotation of the movable unit 140 by the click feeling and thus change the air volume. Further, it is possible to suppress the problem that the movable unit 140 is rotated against the user's will.

In the sperm collecting device 1A of the second embodiment, the second rubber ring 134 is attached to the second cylindrical member 132 in a state in which the distal end inner peripheral surface of the second cylindrical member 132 is opposed to the outer peripheral surface of the bent piece 134b of the second rubber ring 134, and the respective base-side openings 132c (second openings) are aligned with the circumferential positions of the respective rubber-ring-side openings 134c (second openings).

Further, by attaching the outer peripheral surface of the movable tube 142b rotatably in the circumferential direction in a state of facing the inner peripheral surface of the bent piece 134b of the second rubber ring 142, any one of the plurality of rubber ring side openings 134c is positioned inside the movable tube side opening 142g (first opening).

In the example shown in fig. 13(a), the movable cylinder side opening 142g is positioned at the 5 th rubber ring side opening 134c (5) from the left end. As a result, the movable tube side opening 142g, the rubber ring side opening 134c (5), and the base body side opening 132c (5) are communicated with each other, and therefore, air flows inside and outside the container 20 at a flow rate corresponding to the opening area (flow path resistance) of each of the openings 142g, 134c (5), and 132c (5).

In the example shown in fig. 13(b), the movable unit 40 (the cup member 41, the movable ring 42) is rotated clockwise from the state shown in fig. 13(a), and the movable cylinder side opening 142g is positioned on the inner periphery of the rib 134e where the rubber ring side opening 134c is not provided. In this state, air flows only through the gap between the movable unit 40 and the base unit 30, the gap between the insertion space ES and the penis P, and the like, and the stimulation to the penis P is the strongest.

Since the opening areas of the plurality of rubber ring side openings 134c and the plurality of base body side openings 132c are different from each other, the flow rate of air flowing through the inside and outside of the container 20 is adjusted in accordance with the rotation angle of the movable unit 40 with respect to the base unit 30. Therefore, the intensity of the stimulation to the penis P can be adjusted according to the rotation angle.

< sperm collecting device 1B > of the third embodiment

In the sperm collecting device 1A of the second embodiment described above, the single movable cylinder side opening 142g (first opening) is configured by selecting one of a plurality of sets (second openings) of the rubber ring side opening 134c and the base side opening 132c having different opening areas, but is not limited to this configuration.

For example, as shown in fig. 14, one of a plurality of movable cylinder side openings 242d (first openings) having different opening areas may be selectively positioned at one rubber ring side opening 234c (second opening).

Next, a sperm collecting device 1B of a third embodiment configured in this manner will be described. Fig. 14(a) is an exploded perspective view illustrating a main part of a sperm collecting device 1B according to the third embodiment, fig. 14(B) is a view illustrating a movable cylinder side opening 242d provided in a movable ring 242, fig. 15 is a cross-sectional view of the second rubber ring 234, fig. 16(a) is a longitudinal cross-sectional view of the container 20B, and fig. 16(B) is a partially enlarged cross-sectional view of the vicinity of the adjustment mechanism AD 2.

The sperm collection apparatus 1B shown in fig. 14(a) includes: a base-side groove 232c provided at the leading end 232b of the base unit 230 (second cylindrical member 232); a rubber ring side opening 234c (second opening) provided in the second rubber ring 234; and a plurality of movable cylinder side openings 242d (first openings) provided in the movable ring 242.

In addition, in the sperm collecting device 1B of the third embodiment, the same components as those of the sperm collecting device 1 of the first embodiment are given the same reference numerals, and the description thereof will be omitted. The configuration not shown is the same as that of the sperm collecting apparatus 1 according to the first embodiment, and therefore, the description thereof will be omitted.

The base unit 230 includes a first tubular member 231, a second tubular member 232, a first rubber ring 233 (see fig. 16), and a second rubber ring 234, as in the base unit 30 of the first embodiment. The first tube member 231 and the first rubber ring 233 have the same structure as the first tube member 31 and the first rubber ring 33 of the first embodiment. Therefore, the description thereof is omitted.

The second cylindrical member 232 is a cylindrical member having both ends open in the axial direction, and has a substantially V-shaped recess 232a formed along the entire circumference in the axial direction. A portion closer to the base end side than the recess 232a in the second cylindrical member 232 is fitted to the inner circumferential side of the half tip end side of the first cylindrical member 231. As shown in fig. 16, the first rubber ring 233 is sandwiched between the base end of the second cylindrical member 232 and the first cylindrical member 231, and connects the cylindrical members 231, 232 in an airtight state.

The base-side groove portion 232c provided at the distal end 232b of the second cylindrical member 232 is constituted by one groove having an open distal end. In the illustrated example, the base-side groove 232c is formed by a U-shaped groove, but is not limited to this shape. For example, the base-side groove 232c may be a rectangular groove with an open front end.

A plurality of engagement slits 232d are provided at the distal end 232b of the second cylindrical member 232 at positions on the opposite side in the circumferential direction from the base-side groove portion 232 c. Each of the engaging slits 232d is a rectangular slit having an open front end and elongated in the axial direction. In this example, 10 engaging slits 232d are provided at intervals in the circumferential direction.

As shown in fig. 14(a) and 15, the second rubber ring 234 includes: a cylindrical portion 234 a; an annular portion 234b integrated with the distal end of the cylindrical portion 234 a; and a rubber ring side opening 234c provided on a side surface of the cylindrical portion 234 a. The second rubber ring 234 of the third embodiment is also made of a synthetic resin (various rubber materials or an elastic elastomer having rubber) having flexibility and sealing property, as in the second rubber ring 34 of the first embodiment.

The annular portion 234b is provided in a state of being expanded in the outer diameter direction from the distal end of the cylindrical portion 234a and slightly inclined toward the proximal end side.

The rubber ring side opening 234c has a vertically long elliptical shape with a longitudinal length (axial length) longer than a lateral length (circumferential length), and penetrates the thickness direction of the cylindrical portion 234 a. An elliptical rib 234d along the edge of the rubber ring side opening 234c protrudes in the inner diameter direction from the inner peripheral surface of the cylindrical portion 234 a.

The movable ring 242 includes: an annular flange portion 242a that abuts against the annular portion 234b of the second rubber ring 234; and a movable tube 242b provided integrally with the flange portion 242 a. The flange portion 242a is provided with a notch-shaped locking groove 242c into which the base end of a second locking protrusion 41c provided on the inner peripheral surface of the cup member 41 is fitted. Thus, the movable ring 242 rotates about the shaft center together with the cup member 41. In the present embodiment, the movable ring 242 is made of a hard plastic material (e.g., polyacetal resin, polyamide resin) having elastic properties.

As shown in fig. 14(b), the movable tube 242b is provided with a plurality of movable tube side openings 242d (first openings). The movable cylinder side openings 242d are small holes having different opening areas and are provided at intervals in the circumferential direction.

In the present embodiment, 9 movable cylindrical side openings 242d are provided, and the movable cylindrical side opening 242d (1) located at the left end in fig. 14(b) has the smallest opening area, the movable cylindrical side opening 242d (9) located at the right end has the largest opening area, and the opening area gradually increases from the left end toward the right end.

The shape and size of each movable cylinder side opening 242d are determined as the shape and size of the rubber ring side opening 234c housed in the opening. The circumferential distance between adjacent movable cylinder side openings 242d is determined to be the size of one movable cylinder side opening 242d disposed only in the rubber ring side opening 234c, but may be set to be a distance at which a plurality of movable cylinder side openings 242d can be disposed in the rubber ring side opening 234 c.

As shown in fig. 14(a), a guide plate 242e is provided in the inner peripheral surface of the movable cylinder 242b in the range where each movable cylinder side opening 242d is formed. The guide plate 242e is attached to a position spaced radially inward from the inner peripheral surface of the movable cylinder 242b by an attachment rib 242f, and the core member 10 in the tilted state can abut against the inner peripheral surface of the guide plate 242 e.

The guide plate 242e suppresses the problem that each movable cylinder side opening 242d is blocked by the core member 10 in the tilted state. That is, the guide plate 242e can be said to be a guide member for ensuring air permeability of each movable cylinder side opening 242 d.

An engaging projection 242g is formed at a position rotated 180 degrees in the circumferential direction from the position of the guide plate 242e in the movable barrel 242 b. As in the second embodiment, the engaging projection 242g projects outward at the circumferential center portion of the circumferentially elongated plate spring portion 242 h.

The engaging projection 242g engages with an engaging slit 232d provided at the distal end 232b of the second cylindrical member 232. When any one of the plurality of movable cylinder side openings 242d is disposed inside the rubber ring side opening 234c, the engaging projection 242g engages with each engaging slit 232 d. When the engaging projection 242g engaged with the engaging slit 232d moves toward the adjacent engaging slit 232d, the rotation resistance of the movable unit 240 changes in strength (knocking feeling).

The user can recognize the change in the amount of air due to the rotation of the movable unit 140 by the click feeling. Further, it is possible to suppress the problem that the movable unit 140 is rotated against the user's will.

As shown in fig. 16, in the sperm collecting device 1B according to the third embodiment, the base end inner peripheral surface of the movable unit 240 is also arranged to overlap the distal end outer peripheral surface of the base unit 230 in a state facing thereto, and an air flow path AP through which air flows inside and outside the container 20 and an adjustment mechanism AD2 for adjusting the air flow rate of the air flow path AP are provided at the overlapping portion of the peripheral surfaces.

The adjustment mechanism AD2 is constituted by the distal end of the base unit 230 (the distal end 232b of the second cylindrical member 232, the rubber ring side opening 234c) and the proximal end of the movable unit 240 (the movable ring 242, the movable cylindrical side opening 242 d).

An air flow path AP is formed between the base end inner peripheral surface of the cup member 41 and the distal end outer peripheral surface of the base unit 230 by the base side marks 32d (see fig. 4), and the inside and the outside of the container 20B are communicated via the air flow path AP and the adjustment mechanism AD 2. In addition, in the sperm collecting device 1B of the third embodiment, since there is one rubber ring side opening 234c, one base side mark 32d is provided. On the other hand, the movable side marks 41a (see fig. 4) are provided at intervals in the circumferential direction in number corresponding to the number of the movable cylinder side openings 242 d.

Further, the adjustment mechanism AD2 adjusts the air flow rate (air flowability) flowing inside and outside the container 20B according to the area of the one movable cylinder side opening 242d disposed inside the rubber ring side opening 234 c.

Fig. 17(a) is a diagram illustrating a state in which any one of the plurality of movable cylinder side openings 242d is not selected, fig. 17(b) is a diagram illustrating a state in which one of the plurality of movable cylinder side openings 242d is selected, and fig. 17(c) is a diagram illustrating a state in which the other movable cylinder side opening 242d is selected.

In the example shown in fig. 17(a), none of the plurality of movable cylinder side openings 242d is disposed in the rubber ring side opening 234 c. In this state, air flows only through the gap between the movable unit 240 and the base unit 230, the gap between the insertion space ES and the penis P, and the like, and the stimulation to the penis P is the strongest.

In the example shown in fig. 17(b), since the 5 th movable cylinder side opening 242d (5) from the left end is positioned at the rubber ring side opening 234c, the air flows with a flow path resistance corresponding to the area of the 5 th movable cylinder side opening 242d (5). In this state, the stimulation to the penis P becomes weaker than the example shown in fig. 17 (a).

In the example shown in fig. 17(c), the right movable tube side opening 242d (9) having the largest area is positioned at the rubber ring side opening 234c, and therefore, the stimulation to the penis P is further weakened as compared with the example shown in fig. 17 (b).

Thus, in the sperm collecting device 1B of the third embodiment, the flow rate of air flowing inside and outside the container 20B is also adjusted in accordance with the rotation angle of the movable unit 240 (cup member 41) with respect to the base unit 230. Therefore, the intensity of the stimulation to the penis P can be adjusted according to the rotation angle.

< modification example >

In each of the above embodiments, the base end inner peripheral surface of the movable unit 40, 140, 240 is opposed to the tip end outer peripheral surface of the base unit 30, 130, 230, and the second rubber ring 34, 134, 234 having the rubber ring side opening 34c, 134c, 234c is interposed between the two peripheral surfaces, but the present invention is not limited to this configuration.

For example, in the above-described embodiments, the adjustment mechanisms AD, AD1, AD2, and AD 2' are provided at the axial intermediate positions in the container 20, but may be provided at the axial upper ends (upper end side surfaces, upper end surfaces).

Further, the distal end of the base unit 30 and the like may be configured as a double structure of the outer peripheral wall and the inner peripheral wall, and the proximal end of the movable unit 40 and the like may be fitted in the groove between the outer peripheral wall and the inner peripheral wall of the distal end of the base unit, and the second rubber ring 34 and the like may be sandwiched between the proximal end of the movable unit and the inner peripheral wall of the base unit. In this configuration, the proximal end side surface of the movable unit 40 and the like and the inner peripheral wall of the base unit 30 and the like are opposed to each other with the second rubber ring 34 and the like interposed therebetween. Therefore, the same operational effects as those of the above-described embodiments can be obtained by providing the openings in the base end side surface of the movable unit 40 and the like, the inner peripheral wall of the base unit 30 and the like, and the second rubber ring 34 and the like.

In each of the embodiments described above, the insertion space ES of the core 10 and the inner space IS of the container 20 are not communicated with each other, but as shown in fig. 1 and the like, a valve 11f for communicating the inner space IS of the container 20 and the insertion space ES of the core 10 may be provided in the vicinity of the front end of the core 10.

The valve 11f is provided in a part (for example, a distal end portion) of the core member 10, and is a linear cut that penetrates the cylindrical portion 11c in the thickness direction. The valve 11f IS constantly closed by the elasticity of the elastic material itself at ordinary times, and on the other hand, IS opened when the air pressure in the insertion space ES rises above a prescribed level and communicates the insertion space ES with the inside space IS to allow the discharge of air.

Thus, the valve 11f allows air to be discharged from the insertion space ES to the inner space IS of the container 20, and restricts air from flowing into the insertion space ES from the inner space IS of the container 20.

In the adjusting mechanisms AD, AD1, AD2, the flexible piece side opening 42e or the movable tube side opening 142g, 242d is provided in the movable rings 42, 142, 242, and the rubber ring side opening 34c, 134c, 234c or the base side opening 132c is provided in the base units 30, 130, 230 in the above embodiments, but the invention is not limited to these configurations.

The adjustment mechanisms AD, AD1, AD2 may be configured to adjust the air flow rate flowing in and out of the containers 20, 20A, 20B according to the rotation angle of the movable unit 40 with respect to the base unit 30.

Fig. 18 is a diagram illustrating a movable ring 242 'included in a sperm collecting apparatus 1B' according to a modification of the third embodiment, fig. 19(a) is a diagram illustrating a state in which a movable cylinder side opening portion 242j and a rubber ring side opening portion 234c do not overlap, fig. 19(B) is a diagram illustrating a state in which an air flow rate is adjusted to an intermediate level, and fig. 19(c) is a diagram illustrating a state in which the air flow rate is adjusted to a maximum.

As shown in FIG. 18, the sperm collecting apparatus 1B 'is provided with a movable ring 242'. The movable ring 242' includes a movable cylindrical side opening 242j (first opening). The movable cylindrical side opening 242j is elongated in the circumferential direction, and has a shape in which the opening height (the interval in the axial direction) differs depending on the position in the circumferential direction. The movable cylinder side opening 242j illustrated in fig. 18 has a substantially triangular shape elongated in the circumferential direction. Specifically, the movable cylinder side opening 242j has the smallest opening height (axial interval) at one circumferential end (left end) and the largest opening height at the other circumferential end (right end). Therefore, the movable tube side opening 242j has an opening height that increases (continuously increases) from one end in the circumferential direction toward the other end, and an opening height that decreases (continuously decreases) from the other end in the circumferential direction toward the one end. The shape of the movable cylinder side opening 242j is not limited to the example of fig. 18.

As shown in fig. 19, the rubber ring side opening 234c (second opening) provided in the second rubber ring 234 has a circumferential length shorter than the circumferential length of the movable cylinder side opening 242j, and an opening height greater than or equal to the opening height (maximum interval in the axial direction) in the other circumferential end of the movable cylinder side opening 242 j.

In addition, in the sperm collecting device 1B' according to the modification of the third embodiment, the other configurations are the same as those of the sperm collecting device 1B according to the third embodiment, and therefore, the description thereof will be omitted.

In the adjustment mechanism AD 2' shown in fig. 19, the area of the movable cylinder side opening 242j (first opening) located in the rubber ring side opening 234c (second opening) is changed in accordance with the rotation angle of the movable unit 130 with respect to the base unit 230. In the adjusting mechanism AD 2', the flow rate of air (air flowability) flowing through the inside and outside of the container is adjusted according to the area of the movable tube side opening 242j located in the rubber ring side opening 234 c.

In the example shown in fig. 19(a), the movable cylinder side opening 242j is not located in the rubber ring side opening 234 c. In this state, air flows only through the gap between the movable unit 240 and the base unit 230, the gap between the insertion space ES and the penis P, and the like, and the stimulation to the penis P is the strongest.

In the example shown in fig. 19(b), since the circumferential center portion of the movable cylinder side opening portion 242j is located inside the rubber ring side opening portion 234c, air flows through the flow path resistance corresponding to the area of the overlapping portion of the opening portions 234c, 242 j. In this state, the stimulation to the penis P becomes weaker than the example shown in fig. 19 (a).

In the example shown in fig. 19(c), the right end in the circumferential direction of the movable cylinder side opening 242j is positioned inside the rubber ring side opening 234c, and therefore, the stimulation to the penis P is further weakened as compared with the example shown in fig. 19 (b).

The core member 10 is not limited to the structure of fig. 3. For example, the number of the ring members 12 may be 1 or 2, or may be omitted.

The outer shape of the cup member 41 is not limited to a cup shape as long as it can rotate around the axial center with respect to the base unit 30. For example, the outer shape of the cup member 41 may be a rectangular parallelepiped shape.

In the above embodiments, the base side marks 32d are formed by grooves and used as the air flow paths AP, but the present invention is not limited to this structure. A groove may be formed on the inner surface side of the cup member 41, or a gap may be provided between the base end inner surface of the cup member 41 and the distal end outer surface of the second cylindrical member 32.
