Technical Field

The invention relates to a tape core for a tape dispenser.

Background

Conventionally, a tape core is known which is used by winding a tape and attaching the tape to a tape dispenser (for example, see patent document 1).

Recently, a belt with a wide variety of patterns, designs, colors, and the like has appeared, such as a masking belt. In order to enable a plurality of changed tapes to be used quickly, a plurality of tape cores need to be prepared and the tapes need to be individually wound around the tape cores.

However, in this case, the number of cores of the belt is excessively increased, and the cores are easily dispersed, which may cause a very complicated management. In particular, if the belt core is relatively small, it may be lost during carrying.

The tape pushing portion C constitutes a leading end portion separating means for separating the leading end portion st of the tape T from the cutting portion 5.

The tape dispenser D of the present embodiment is a relatively small tape dispenser having a front-rear direction dimension set to about 3 cm.

The respective structures of the tape dispenser D will be described in detail below.

< < tape dispenser body A >)

The tape dispenser body a includes: left and right side walls 1, 2; a replacement support shaft 3 as a belt body support part, which is erected between the left and right side walls 1, 2; a holding section 4 which is provided between the left and right side walls 1, 2, temporarily adheres thereto, and holds the tape T pulled out from the tape body R; and a cutting section 5 which is provided between the left and right side walls 1, 2 and has a blade 51 for cutting the tape T drawn out from the tape body R.

< left and right side walls 1, 2 >

The left and right side walls 1, 2 are paired and have substantially the same shape. The left and right side walls 1 and 2 are formed into a substantially horizontal egg shape having a shape in which the vertical dimension thereof gradually becomes shorter toward the front side.

The left and right side walls 1, 2 include: a rear partial arc edge e1 having a partial arc shape in side view; a straight edge e2 which extends forward continuously from the rear partial arc edge e1 and forms an upper part of the upper edge; a lower straight edge e3 which extends forward continuously from the rear partial arc edge e1 and forms a lower edge portion; and a front partial arc edge e4 which is partially arc-shaped in side view and connects the front end of the upper straight edge e2 and the front end of the lower straight edge e 3. Further, in the left and right side walls 1 and 2, the upper straight edge e2 and the lower straight edge e3 are formed in shapes gradually approaching from the rear side toward the front side.

As shown in fig. 5, the left side wall 1 has a plurality of concave portions 11 as engaging portions on the outer surface thereof, which constitute a coupling portion S that can be coupled to the core M. In this embodiment, the recesses 11 are disposed at six locations. The six recessed portions 11 are provided at substantially equidistant positions from the axial center of the replacement support shaft 3 so as to surround the axial center. The adjacent recesses 11 of the six recesses 11 are arranged at equal intervals from each other.

A plurality of, that is, two, upper and lower, anti-slip projections 12 capable of being caught by the user's fingers are provided at the rear end edge of the left side wall 1.

The dummy support shaft 3, the holding portion 4, and the cutting portion 5 are provided on the inner surface of the left side wall 1 so as to protrude toward the right side wall 2 in this order from the rear. A ring-shaped recessed portion 13 is formed around the dummy support shaft 3 on the inner surface side of the left side wall 1, in which the left side plate M3 of the tape core M is disposed.

In the recessed portion 13, a protruding portion 21 protruding from a side plate M2 on the right side when the tape core M is attached to the tape dispenser body a while being inverted left and right is housed.

As shown in fig. 4, the right side wall 2 has a plurality of projections 21 as engagement portions that constitute a coupling portion S that can be coupled to the belt core M, provided on the outer surface side of the rear portion. In this embodiment, the projections 21 are disposed at two locations. The two projections 21 are provided at substantially equidistant positions from the axial center of the replacement support shaft 3. The two convex portions 21 are symmetrically arranged around the axial center of the dummy support shaft 3.

On the inner surface of the side wall 2 on the right side, there are provided in order from the rear to the front: a cylindrical support shaft support member 22, the support shaft support member 22 being inserted into a hollow portion 31 in a dummy support shaft 3 provided upright on a side wall 1 on the left side; a plate-shaped holding portion support member 23, the holding portion support member 23 being inserted into a hollow portion 41 in the holding portion 4 provided upright on the left side wall 1; and a fitting recess, not shown, into which a fitting projection 52 provided upright at the tip end of the cut portion 5 of the left side wall 1 can be fitted.

When the refill B is mounted to the tape dispenser body a, first, the left side wall 1 and the right side wall 2 are separated, and the refill support shaft 3 provided on the left side wall 1 is inserted into the shaft hole m11 of the refill B. Next, the left and right side walls 1 and 2 are butted against each other, and the support shaft support member 22, the holding portion support member 23, and the not-shown fitting recess provided in the right side wall 2 are engaged with the hollow portion 31 of the replacement support shaft 3, the hollow portion 41 of the holding portion 4, and the fitting projection 52 provided in the left side wall 1. The replacement B is held in a state capable of being used with the tape dispenser main body a. On the other hand, if the left and right side walls 1 and 2 are separated from each other, the replacement B can be removed or replaced with another replacement B.

< replacement support shaft 3 >

The replacement support shaft 3 is formed to extend in the left-right direction. The replacement support shaft 3 is cylindrical, and a support shaft support member 22 provided upright on the right side wall 2 is inserted into an inner hollow portion 31.

The replacement support shaft 3 is capable of rotatably supporting a replacement B that holds a tape body R formed by winding a tape T in a roll shape. That is, the refill support shaft 3 is inserted into the shaft hole m11 formed in the cylindrical portion m1 of the refill B and penetrating in the left-right direction.

< holding part 4 >

The holding portion 4 extends in the left-right direction. The holding portion 4 is disposed at a position forward of the replacement support shaft 3. The holding portion 4 has a square tubular shape, and a holding portion support member 23 provided upright on the right side wall 2 is inserted into an inner hollow portion 41.

The holding portion 4 has a tape adhesion portion 42 on the upper end surface, which can temporarily adhere a part of the tape T drawn out from the tape body R. The tape bonding portion 42 is formed of an inclined surface that gradually decreases from the rear side toward the front side in side view. Further, the tip of the knife 51 in the cutting section 5 is located on an imaginary extension line of the tape bonding section 42.

The front surface of the holding portion 4 is a standing surface. The back surface of the holding portion 4 is a curved surface whose vertical intermediate portion is recessed forward from the vertical end portions so as not to interfere with the replacement B supported by the replacement support shaft 3. The lower surface of the holding portion 4 is an inclined surface gradually descending from the front to the rear.

< cutting part 5 >

The cutting section 5 extends in the left-right direction and has a knife 51 at an upper end portion thereof capable of cutting the tape T drawn out from the tape body R. The cutting portion 5 is disposed at a position forward of the holding portion 4. The cutting portion 5 is in the form of a standing plate. A fitting protrusion 52 fitted into a not-shown fitting recess formed in the right side wall 2 is provided at an extending end of the cut portion 5 extending from the left side wall 1.

Upper and lower engaging recesses 53 and 54 recessed in a mountain shape are formed in two upper and lower portions on the back surface of the cut portion 5. The upper and lower locking recesses 53 and 54 constitute a resistance portion U described later in cooperation with the elastic engagement portion 62 of the belt pushing-out portion C.

< replacement B >)

The replacement B is constituted by a belt core M and a belt body R that winds the belt T in a roll shape with respect to the belt core M.

The belt core M holds the belt body R formed in a roll shape by winding the belt T. The tape core M is attached to the tape dispenser body a for use.

The belt core M includes: a cylindrical portion m1 provided at the center and extending in the left-right direction; a pair of left and right side plates m3, m2 provided at left and right ends of the cylindrical portion m1, respectively, the pair of left and right side plates m3, m2 being provided at left and right ends of the cylindrical portion m 1; and a coupling section S provided on the left and right side plates M3, M2 and capable of coupling to another belt core M having the same shape.

As will be described in detail later, the belt core M of the present embodiment is configured to be connectable to another belt core M having the same shape via the connecting portion S.

< cylindrical part m1 >

The cylindrical portion m1 is cylindrical and penetrates in the left-right direction. That is, the cylindrical portion m1 has a shaft hole m11 into which the dummy support shaft 3 is inserted. The tape core M is rotatably supported with respect to the tape dispenser main body a by inserting the refill support shaft 3 provided to the tape dispenser main body a into the shaft hole M11 of the cylindrical portion M1.

< left and right side plates m3, m2 >

The left and right side plates m3, m2 each have a substantially annular shape in side view, extending in a flange-like manner from the end edge of the cylindrical portion m 1.

< connecting part S >

The coupling portion S provided in the belt core M is used to couple to another belt core M having the same structure. In this embodiment, since the coupling portions S are provided on the left and right side plates M3, M2 of the belt core M, the other belt core M having the same structure can be coupled to the belt core M left and right.

In other words, if a plurality of replacements B each of which is formed by winding the tape T around the core M are prepared, the plurality of replacements B can be connected in series by the connecting portion S in the transverse direction.

The connection portions S are provided on the left and right side plates m3, m2, respectively. More specifically, the coupling portion S is constituted by a convex portion r1 provided on the right side plate m2 as one side plate and an engaging hole r2 as an engaging portion provided on the left side plate m3 as the other side plate and with which the convex portion r1 can be engaged.

The convex portion r1 of the side plate M2 on the right side of the belt core M is fitted into the engaging hole r2 provided in the side plate M3 on the left side of the other belt core M having the same structure, whereby the two belt cores M, M can be coupled to each other.

The engagement hole r2 provided in the left side plate M3 of the belt core M is externally fitted to the projection r1 provided in the right side plate M2 of the other belt core M having the same structure, whereby the two belt cores M, M can be coupled to each other.

First, the convex portion r1 of the side plate m2 provided on the right side will be described.

The protruding portion r1 has a cylindrical shape. The convex portion r1 protrudes outward from the outer surface of the right side plate m 2. The protruding portions r1 are arranged in a plurality of, two, positions. The two convex portions r1 are provided at substantially equidistant positions from the axis of the cylindrical portion m 1. The two convex portions r1 are arranged at substantially symmetrical positions around the axial center of the cylindrical portion m 1.

Next, the engaging hole r2 provided in the left side plate m3 will be described.

The engagement hole r2 is formed in a circular hole shape having a size capable of fitting into the cylindrical projection r 1. The engaging hole r2 is a through hole penetrating in the left-right direction. The engaging holes r2 are disposed in a plurality of, that is, six locations. The six engaging holes r2 are provided at substantially equidistant positions from the axial center of the cylindrical portion m1 so as to surround the axial center. The six engaging holes r2 are arranged at equal intervals.

In this embodiment, the number of the engagement holes r2 provided in the left side plate m3 is set to be larger than the number of the convex portions r1 provided in the right side plate m 2. By setting the convex portion r1 and the engagement hole r2 of the tape core M in this manner, the operation for connecting the convex portion r1 of the tape core M to the engagement hole r2 of another tape core M is facilitated.

That is, since the user can operate the two-part convex portions r1 to be fitted into any one of the six engagement holes r2, the tape core M can be connected to another tape core M by a light butting operation (an operation of butting the convex portions r1 and the engagement holes r2 with a rough feeling) of the convex portions r1 and the engagement holes r 2.

Further, by making the number of the convex portions r1 smaller than the number of the engagement holes r2, the number of the convex portions r1 which are easily conspicuous in shape and easily deteriorate the design can be suppressed, which contributes to ensuring a suitable appearance of the entire belt core M.

Further, since adjustment of the mold for forming the protruding portion r1 requires a relatively large number of steps, the number of steps for adjustment of the mold is reduced by making the number of the protruding portions r1 smaller than the number of the engaging holes r 2.

As shown in fig. 12 to 14, the coupling portion S of the tape core M is configured to be able to couple to the coupling portion S (the concave portion 11 or the convex portion 21) provided on the left and right side walls 1 and 2 of the tape dispenser body a, which is an outer portion of the tape dispenser D.

As shown in fig. 15 to 17, the coupling portion S (the convex portion r1) of the tape core M is configured to be able to be coupled to the coupling portion S (the engaging hole K1) of the rotating plate K directly coupled to the operating handle J provided on the tape rewinder E. Further, a more specific configuration of the tape rewinder E will be described in detail later.

< Belt ejecting section C >

The tape pushing portion C is supported to be able to advance and retreat with respect to the tape dispenser main body a. The tape pushing portion C is configured to be movable relative to the tape dispenser main body a by a user's operation and to push out the tape T in a direction intersecting the extending direction of the tape T.

The tape ejecting section C includes: an upper portion 6, the upper portion 6 having a push-out head 61 formed at an upper end thereof to be in contact with the adhesive surface nm side of the tape T and extending in the vertical direction; and a lower part 7, wherein the lower part 7 extends from the lower end part of the upper part 6 to the lower part obliquely back. The tape ejecting section C is shaped like "く" in side view by the upper section 6 and the lower section 7.

< upper part 6 >

The upper portion 6 is formed in a plate shape extending in the left-right direction and the up-down direction as a whole. The upper portion 6 includes: a push-out head 61, the push-out head 61 being provided at an upper end portion and capable of contacting the tape T; and an elastic engagement portion 62 provided in a cantilever shape on the right side when viewed from the front of the vertical intermediate portion such that the lower end portion thereof becomes a free end, the elastic engagement portion 62 having a locking convex portion 62a capable of locking with the upper and lower locking concave portions 53 and 54 in the cutting portion 5 at a tip end portion which is a lower end portion. The upper portion 6 is located in a gap sk extending in the vertical direction formed between the cutting portion 5 and the holding portion 4, and is movable in the vertical direction while being guided by the gap sk.

The push-out head 61 has a movement restricting portion 61a formed at a position lower than the upper end and protruding forward. The movement restricting portion 61a is engaged with an upper portion of the cutting portion 5 when the tape ejecting portion C is located at the retreat position (Q), and can restrict the movement of the tape ejecting portion C to a position below the retreat position (Q).

The elastic engagement portion 62 constitutes a resistance portion U that prevents the belt pushing portion C from moving to the pushing position (P) or the retracted position (Q) until a predetermined pressing force is applied. That is, the elastic engaging portion 62 selectively engages with either one of the locking recess 53 provided above and the locking recess 54 provided below the cutting portion 5, and can lock the belt ejecting portion C at the ejecting position (P) and the retracted position (Q).

More specifically, when the tape ejecting section C is located at the ejecting position (P), the locking convex portion 62a of the elastic engaging portion 62 is elastically engaged with the upper locking concave portion 53 of the cutting portion 5, whereby the tape ejecting section C can be held at the ejecting position (P). When the tape ejecting section C is located at the retracted position (Q), the locking convex portion 62a of the elastic engaging portion 62 engages with the lower locking concave portion 54 of the cutting portion 5, whereby the tape ejecting section C can be held at the retracted position (Q).

< lower part 7 >

The lower portion 7 is plate-shaped and extends obliquely downward and rearward integrally from the lower end of the upper portion 6.

The lower portion 7 of the tape pushing portion C has a pressed portion 71 which is located below the holding portion 4 in the tape dispenser main body a and can receive a pressing operation in an upward direction by a user. That is, the pressed portion 71 of the belt pushing-out portion C located at the retreat position (Q) is pressed upward by the finger of the user, and the belt pushing-out portion C can move to the pushing-out position (P) against the resistance generated by the resistance portion U.

In this process, the tape pushing section C pushes the tape T pulled out from the tape body R upward from below. When the tape ejecting section C reaches the ejecting position (P), the tip portion st of the tape T is separated from the cutting section 5 to such an extent that the user's finger tip enters, and the user can easily pinch the tip portion st of the tape T with his finger.

The tape ejecting section C is configured to be movable between an ejecting position (P) located on the tape track kd between the tape body R and the cutting section 5 and a retracted position (Q) retracted from the tape track kd.

In this embodiment, the tape pushing portion C is provided between the cutting portion 5 and the holding portion 4. In other words, the tape pushing unit C is held so as to be movable up and down by the cooperation of the cutting unit 5 and the holding unit 4.

While moving from the retreat position (Q) to the push-out position (P), the tape push-out portion C can come into contact with the lower surface of the tape T, i.e., the adhesive surface nm side, and push out the tape T upward.

In this embodiment, the tape ejecting section C located at the ejecting position (P) is configured to be automatically movable in the direction of the retracted position (Q) in response to the cutting operation of the tape T by the user. That is, when the user pulls out the tape T of a certain size to the outside, i.e., to the front while pinching the distal end portion st of the tape T, and then lowers the tape T while tensioning the tape T to perform the cutting operation by the cutter 51, the tape pushing portion C is pushed down by the tape T and can move to the retracted position (Q).

A resistance part U is provided between the tape ejecting part C located at the ejecting position P and the tape dispenser body A. Therefore, when the resistance portion U receives a predetermined downward pressing force in association with the cutting operation (operation of lowering the tape T) by the user, the tape pushing portion C can move in the direction of the retreat position (Q) against the resistance generated by the resistance portion U.

< < tape recoiler E >)

A description will be given of a tape rewinder E having a structure in which a tape core M constituting a refill B can be connected via a connecting portion S.

As shown in fig. 15 to 17, the tape rewinder E can rewound the tape TL drawn out from the prepared tape body L on the tape core M. The tape rewinder E rotatably holds a finished tape body L in which a tape TL is wound in a roll shape. Further, the tape rewinder E is provided with an operation handle J that is rotationally operated by the user. A rotating plate K rotatable integrally with the operation handle J is provided at a base end portion of the operation handle J. The tape rewinder E can mount the tape core M of the tape dispenser D to the rotating plate K.

That is, the tape rewinder E can rewind the tape TL drawn out from the prepared tape body L around the tape core M connected to the rotating plate K by the rotational operation of the operating handle J. The tape rewinder E can subdivide a part of the tape TL from the prepared tape body L toward the tape core M by pulling out the tape TL from the prepared tape body L and then winding the tape TL around the cylindrical portion M1 of the tape core M again.

The tape rewinder E includes: a base body F capable of assuming a holding posture (a) in which the belt core M can be held without being detached and a detachable posture (b) in which the belt core M can be attached to and detached from the rotary plate K; a tape holding portion G capable of supporting a manufactured tape L to be rotatable with respect to a base F; an operating handle J supported to be rotatable with respect to the base body F; a rotating plate K which rotates integrally with the operating handle J and is provided with a connecting part S which can be connected with the belt core M; and a tape core M configured to be attachable to and detachable from the rotating plate K.

The rotating plate K is provided with engaging holes K1 as coupling portions into which the two projections r1 can be fitted at positions corresponding to the projections r1 as two coupling portions provided on the tape core M. The tape core M is attached to the rotary plate K via the coupling portion in a state where the base body F is in the detachable posture (b), and then the second base member F2 in the expanded posture (d) is changed to the use posture (c), whereby the base body F in the holding posture (a) can hold the tape core M so as to be rotatable integrally with the operation handle J.

The base F is provided with: a first base member f1, the first base member f1 having one rising wall f 11; a second base member f2 having the other rising wall f21, the second base member f2 being configured to be capable of assuming a use posture (c) in which the other rising wall f21 is substantially parallel to the first base member f1 and a deployed posture (d) in which the other rising wall f21 is substantially parallel to a mounting surface such as a ceiling plate; and a lock mechanism N capable of locking the second member in the use posture (c).

As described above, the tape core M according to the present embodiment is used by winding the tape T and attaching the tape T to the tape dispenser D. The belt core M can be connected to another belt core M having the same shape via the connection portion S. Therefore, the belt core M configured such that the plurality of belt cores M are hardly dispersed can be provided.

That is, even when a plurality of tape cores M are prepared and the tapes T are wound around the tape cores M independently from each other, the tape cores M can be coupled to each other by the coupling portion S, for the tape T having a large variety of patterns, colors, and the like.

Therefore, even when the number of tape cores M holding the tape T increases, management becomes difficult to be complicated. In other words, the user can quickly select a tape T to be used from the plurality of coupled tape cores M, and can use the tape T by incorporating the tape T in the tape dispenser D.

Further, as in the present embodiment, even a relatively small tape core M is suitably suppressed from being lost during carrying or the like.

Further, by connecting a plurality of belt cores M, the belt T having a large variation in pattern, color, and the like can be collected into a regularly arranged state. Therefore, for example, as shown in the example of fig. 14, even when not in use, the decoration can function as a decoration that is easy to stay on the viewer visually and that is easy to feel beautiful.

The belt core M includes side plates M3 and M2 paired right and left, and the coupling portions S are provided on the side plates M3 and M2, respectively.

Therefore, not only the other belt core M having the same shape can be connected to the left side plate 3M of the belt core M, but also the other belt core M having the same shape can be connected to the right side plate M2.

The connection part S is provided with: a convex portion r1 provided on the right side plate m2 as one side plate r 1; and an engagement hole r2 as an engagement portion, the engagement hole r2 being provided in the left side plate m3 as the other side plate and being capable of engaging with the projection r 1.

Therefore, the protruding portions r1 of the belt core M are fitted into the engagement holes r2 of the other belt core M, or the engagement holes r2 of the belt core M are fitted to the protruding portions r1 of the other belt core M, whereby both belt cores M can be appropriately connected to each other.

The number of engagement holes r2 as engagement portions provided in the left side plate m3 as the other side plate is set to be larger than the number of convex portions r1 provided in the right side plate m2 as the one side plate.

Therefore, the operation for connecting the convex portion r1 of the tape core M to the engagement hole r2 of another tape core M can be performed relatively easily.

In this embodiment, the user can operate the two-part convex portions r1 to fit into any of the six-part engagement holes r 2. Therefore, the user can connect the tape core M to another tape core M by an operation of easily butting the protruding portion r1 and the engaging hole r2 (an operation of butting them with a rough feeling).

Further, by making the number of the convex portions r1 smaller than the number of the engagement holes r2, the number of the convex portions r1 which are easily conspicuous in shape and may impair the appearance can be suppressed, which contributes to ensuring a proper appearance of the entire belt core M.

Further, in the process of manufacturing the belt core M, since the adjustment of the mold for forming the protruding portion r1 requires a large number of man-hours, the number of the protruding portions r1 is smaller than the number of the engaging holes r2, which contributes to reduction of man-hours required for the adjustment of the mold.

The coupling portion S is configured to be able to couple to the outer surfaces of the left and right side walls 1 and 2, which are the outer portions of the tape dispenser D.

Therefore, the tape core M not incorporated in the tape dispenser D can be coupled to one or both of the left and right side walls 1 and 2. Therefore, the user can select the tape core M on which the tape T to be used is wound from the plurality of tape cores M connected to the tape dispenser D, and can quickly attach the tape core M to the tape dispenser D for use.

Further, since the unused tape core M can be coupled to the tape dispenser D directly or indirectly via the tape core M, scattering of the tape core M can be appropriately suppressed, and loss of the tape core M can be appropriately suppressed.

The coupling portion S of the tape core M is also configured to be directly coupled to the rotating plate K coupled to the operating handle J provided in the tape rewinder E. The tape rewinder E can rewind the tape LT drawn out from the already-manufactured tape body L wound in a roll shape from the tape LT around the tape core M coupled to the rotating plate K by the rotating operation of the operating handle J.

Therefore, the tape core M can be stably attached to the tape rewinder E via the connection portion S and used. In other words, the core M is a member that can be used to rewind the tape TL for the purpose of subdividing the tape LT of the already-manufactured tape body L. For example, if a plurality of tape cores M are prepared, and the tape rewinder E is operated by sequentially mounting the tape cores M on the rotating plate K, the tape TL on which the prepared tape body L is formed can be divided into a plurality of tape cores M. Since the tape core M is coupled to the rotary plate K via the coupling portion S, the tape TL subdivided from the already-manufactured tape body L is appropriately wound around the tape core M.

Furthermore, the present invention is not limited to the above-described embodiments.

The kind of the tape may be applied to various types, and is not limited to the masking tape.

The tape dispenser incorporating the tape core is not limited to the tape dispenser shown in the above embodiment.

The specific form of the coupling portion is not limited to the form of the projection and the engagement hole as described above. For example, the coupling portion may be a coupling portion that can couple the tape core and another tape core having the same shape by a magnet, or may be a coupling portion that can couple by a surface fastener (hook and loop fastener).

The left and right side plates are not necessarily formed in an annular shape (ring shape), and may be polygonal side plates, elliptical side plates, or asymmetric side plates.

The engaging portion with which the protruding portion can be engaged may be a recessed portion limited to the engaging hole.

In the above embodiment, the number of the engaging portions provided on the other side plate is set to be larger than the number of the convex portions provided on the one side plate, but the present invention is not limited to such a configuration. For example, the number of the engaging portions and the number of the convex portions may be set to be the same. For example, the number of engaging portions provided on the other side plate may be set smaller than the number of protruding portions provided on the one side plate.

The specific configuration of each portion is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.
