Technical Field

The invention relates to a device for applying a rod-shaped abradable material, having a material carrier and a protective housing for the material carrier, wherein the material carrier can be moved relative to the protective housing in order to move a free end region of the material into a freely protruding position, wherein a movement element having a longitudinal slot is provided in which the material carrier is guided by means of a pin engaging in the longitudinal slot and can be moved between a retracted position and an extended position, wherein the longitudinal slot has a retaining section in correspondence with the extended position, the central longitudinal axis of which extends at an angle to the central longitudinal axis of the movement section of the longitudinal slot.

Background

Devices of the type mentioned are, for example, in the form of a bar, which has a removable mass, which is removable, for example, as a result of friction. Such sticks are also known, for example, as lipsticks, but also as sticks for applying care products, in particular skin care products, or for applying medical products.

For example, reference DE 102016116134 a 1. From this disclosure, it is known to guide a piston-like material carrier in a moving element designed as a slotted sleeve in such a way that a direction of movement of the material carrier in the direction of the longitudinal axis of the device can be achieved thereby. The movement section of the longitudinal slot, which runs essentially in the longitudinal extension direction of the device, is transferred in accordance with the extended position of the material carrier into a holding section running essentially at right angles to the movement section. The pins of the material carrier are guided into the holding section in the extended position, wherein in this position the material carrier can encounter a movement obstacle in the direction of extension of the longitudinal axis.

Disclosure of Invention

With regard to the above-mentioned prior art, the technical problem underlying the present invention is to further improve a device of the type in question, in particular with regard to operating technology.

A possible solution to this problem is provided on the device side according to the first inventive concept, wherein in accordance therewith: the central longitudinal axis of the holding section and the central longitudinal axis of the moving section enclose an obtuse angle, which is preferably between 100 and 170 degrees.

Due to this design, the device is improved, in particular with regard to operating technology. The displacement of the material carrier, in particular from the retracted position in the direction of the extended position, which is carried out as a result of user intervention, is further simplified, in particular with regard to the transition of the guidance of the pin from the linearly axially extending movement section to the holding section.

The holding section preferably also provides an end stop for the material carrier to protrude, so that the material carrier is further preferably held in the movement without being lost.

It is further preferred that a movement obstacle can be created in the material carrier when the pin on the material carrier side engages into the holding section. In the direction of the extended position, such a movement obstacle is preferably constituted by a stop. In the direction of the retracted position, with the pin engaging in the retaining section, the movement obstacle can, if necessary, be formed only by an obtuse angle which is preferably provided between the central axis of the movement section and the central axis of the retaining section.

The transition of the pin displacement from the moving section to the holding section is simplified and made easier by the arrangement of the obtuse angle, and furthermore, preferably with less effort than in the solutions known from the prior art.

The obtuse angle may range between 100 and 170 degrees, further about 110 to 130 degrees, further for example about 115 to 120 degrees.

On the apparatus side, another possible solution to the technical problem is given according to another inventive idea, wherein accordingly: a friction cam is formed on the material carrier and is in frictional contact with an inner surface of the moving member as the material carrier moves.

The arrangement of the friction cam on the material carrier can lead to a self-locking of the material carrier, in particular in an intermediate position between the retracted position and the extended position, further in particular in the following intermediate position: in this intermediate position, the pins of the material carrier engage into a movement section which extends essentially in the longitudinal axis of the device.

The friction cam can be designed such that a self-locking of the material carrier can be achieved up to a load of 6g or more, further for example up to a load of 8g or 10 g.

The friction cam can be formed integrally with the material carrier and/or in material-matched fashion in the form of a projection which projects outwardly in comparison with the other circumferential, preferably cylindrical, material carrier wall.

A plurality of such friction cams may be arranged relative to the axis of movement of the material carrier, which further preferably may correspond to the orientation of the longitudinal axis of the device, on the basis of the circumference of the material carrier. Furthermore, the friction cams may be arranged uniformly distributed over the circumference, but may also be arranged non-uniformly distributed.

The friction cam may also be used to improve the tactile feel of the device when in use. The guidance of the material carrier in the movement member as a whole can also be improved by the arrangement of the friction cams, and further in particular by preventing the material carrier from tilting in the movement member due to the friction cams bearing on the inner surface of the movement member.

The features of the independent claims mentioned above may be used individually or in any combination with one another, where other features of an independent claim can be combined with features of another independent claim or with only a single feature of another independent claim.

Further features of the invention are set forth below and in the description of the figures, in general in their preferred correspondence with the content of claim 1 and/or other independent claims or with the features of other claims. However, other features may also be of significance in correspondence with only a single feature of claim 1 and/or of the further independent claim or of the respective further claim, or of significance independently of each other.

The material carrier can thus be (further) accommodated in a mating holding cylinder in which a control recess for the pin is formed on the inner wall side and wherein the control recess has an inclined surface corresponding to the projecting position, which inclined surface leads to a transition into the cylindrical inner surface of the mating holding cylinder, wherein the pin in the projecting position does not overlap or only partially overlaps the inclined surface.

Due to the above-described formation of the inclined surface of the control groove on the end portion side, a transition of the control groove into the cylindrical inner surface of the fitting retaining cylinder, which is continuous as necessary, preferably not stepped in any case, is constituted. This may prove to be advantageous for assembly, in particular in connection with the assembly of the piston. Furthermore, such a design may prove to be advantageous in the production of a mating holder cartridge, for example in the possible demolding of a mating holder cartridge in a plastic injection molding process.

Even if the pin only partially overlaps the inclined surface in the protruding position, there is an advantageous interaction between the pin and the control groove. In particular in the extended position, the formation of debris can therefore be suppressed, in particular in the region of the pin on the material carrier side. It can prove particularly advantageous if, as provided in one possible embodiment, the entire device or at least the material carrier and the fitting retaining cylinder are made of the same material, respectively preferably of the same material.

In this case, at least the material carrier and the mating holder cylinder can be provided, but preferably also the moving part and, if appropriate, the additional closure cap provided, in particular in a plastic injection molding process, are made of only one plastic material. In this regard, polypropylene (PP) may be used as the plastic.

According to a further embodiment, the retaining section of the longitudinal slot in the movement element can have a locking projection which can be passed over by a pin of the material carrier for retaining the material carrier in particular in the extended position.

Furthermore, it is preferred that the locking projection is not only overridable when the pin enters the holding section, but also during the displacement of the pin back from the holding section in the direction of the movement section. Thus, when entering into the holding section, the user gets a tactile feedback, accompanied by the locking protrusion being crossed. The passing-over locking projection is accompanied by an increased expenditure of force compared to the usual displacement of the pin along the preferably linearly axially extending movement section, as is the passing-over locking projection for displacing the material carrier from the extended position outwards in the direction of the retracted position. However, the increased effort for overcoming the locking projection is within the usual effort for operating devices of the type in question.

As a result of the formation of the latching projection, in particular in the region of the retaining section corresponding to the extended position, it is advantageously possible to produce an extended end position which can only be cancelled by overcoming the retaining force. This may result in advantageous operation of the device. The normal pressure on the material which in the extended position projects freely beyond the co-operating retaining cylinder and preferably also beyond the movement element can be supported by an overrideable locking holder in the region of the retaining section.

In addition, this can lead to advantages in terms of filling the material carrier with material. This filling may take place in the uppermost position, in the above-mentioned extended position, in which the material carrier must, if necessary, be subjected to a pressure in the direction of displacement of the material carrier from the extended position in the direction of the retracted position, for example up to 20 newtons.

According to another possible embodiment, two opposing longitudinal slots can also be formed in the movement element. In the case of a possible cylindrical design of the movement element, the longitudinal slots can be arranged diametrically opposite or diagonally opposite one another relative to a plane oriented transversely to the longitudinal axis of the movement element.

In this case, each longitudinal slot can also be used for receiving a pin of the material carrier. Accordingly, two opposing pins can be provided on the material carrier in the case of two opposing longitudinal slots.

In the case of a movement designed with two longitudinal slots, the two longitudinal slots can have an overridable locking projection in the respective retaining section. The locking projections of the two retaining sections can be designed identically here.

A further holding section can also be provided in relation to the retracted position of the material carrier, wherein the central axis of the holding section and the central axis of the movement section of the longitudinal slot can also enclose an obtuse angle of, for example, 100 degrees to 170 degrees, further, for example, 110 degrees to 130 degrees.

In this case, it is also possible to provide, with respect to a possible retaining section corresponding to the retracted position of the material carrier, a locking projection which can be passed over in both directions, which is similar or identical to the locking projection in the retaining section corresponding to the extended position, so that the reaching of the retracted position is actually recognizable to the user. The crossing of the locking projection is accompanied by an increased force expenditure compared to the usual linear displacement of the material carrier in the movement section.

The maximum retracted position is preferably reached when a locking projection, which is provided if necessary in the retaining section corresponding to the retracted position, is passed over. This may lead to damage of the device parts, in particular the pins of the material carrier, due to the further performed rotational displacement of the moving part relative to the mating holding cylinder. In this case, it has proven to be correspondingly advantageous to design the maximum possible retracted position of the material carrier to be overridden, as also proposed. For this purpose, according to a preferred embodiment, the control recess in the mating retaining cylinder can end gradually in an edge-open manner on the foot side, i.e. in correspondence with the retaining section of the movement element corresponding to the retracted position. With a further applied rotational displacement of the movement element relative to the mating holding cylinder, the pins of the material carrier can thus be adjusted radially inward, so that with a further passage of the corresponding longitudinal slot, in particular of the holding section associated therewith, the pins are pushed out of the control groove or grooves of the mating holding cylinder, in order then to sweep the pins along the preferably cylindrical inner wall of the mating holding cylinder as a result of the further rotational displacement until the pins sink again into the next control groove in the circumferential direction.

Here, the user is also informed in a tactile manner of the end position that can be passed over in the retracted position. Thereby suppressing damage to the device components.

As is also preferred, the maximum extension of the material carrier can conversely be designed so as not to be exceeded or to be passed over. The respective pin of the material carrier can be held captive in this maximum extended position between the stepped edge region of the holding section of the movement element and the control recess of the mating holding cylinder.

A control groove may be formed in the mating retention cylinder for each pin. In a preferred embodiment of the material carrier with two diagonally opposite pins, the counter-holding cylinder can be provided with two, if appropriate, thread-like staggered control recesses on the inside of the wall.

The control recess in the mating holder cylinder can be designed in such a way that a rotation of the movement element between the maximum retracted position and the maximum extended position of the movement element relative to the mating holder cylinder of two to three turns, further for example 2.5 turns, but can also be smaller than two turns, for example 0.5 to 1 turn, further in particular 0.75 turn.

The two control recesses can have an inclined surface of the type described in correspondence with the projecting position.

In a further embodiment, the friction cam can be designed as a non-circular shape with a longer dimension and a shorter dimension, wherein the longer dimension is essentially given in the direction of the movement section. The shorter dimension can be given here in the circumferential direction of the material carrier. Furthermore, the longer dimension of the friction cam can extend in the general displacement direction of the material carrier.

In a further embodiment, the maximum dimension in the transverse direction, i.e. the maximum dimension of the above-mentioned transversely oriented shorter dimension, can be given off-centre from the maximum dimension in the longitudinal direction, when the edge of the friction cam is viewed from the radial outside. Thus, in an upright position of the device, in which the longitudinal axis of the device is preferably oriented substantially vertically and the opening, through which said material can be slidingly displaced outwards, is arranged lower than the center of the maximum dimension of the locking projection in the longitudinal direction.

In a further embodiment, the edge of the friction cam can therefore have a generally approximately drop-shaped contour, with reference to a view from the outside in the radial direction. Furthermore, in this case, the gradually narrowing and tapering end region may be directed upward as described above with reference to the upright state, while the comparatively blunt and widely shaped water droplet arch may be directed downward.

In particular, by means of the above-described design of such a friction cam, a reduced tendency to wear can be determined in the case of a desired increase in the friction of the material carrier relative to the moving part and a guidance reliability against tilting.

The ranges or value ranges or ranges specified above and below in connection with the disclosure also include all intermediate values, in particular 1/10 steps in the respective dimension, possibly also dimensionless. For example, the description of 100 degrees to 170 degrees also includes disclosure of 100.1 degrees to 170 degrees, 100 degrees to 169.9 degrees, 100.1 degrees to 169.9 degrees, and the like. Such disclosure may be used on the one hand to limit the mentioned range limits from below and/or from above, but also alternatively or additionally to disclose one or more individual values from the respective stated range.

Detailed Description

Shown and described first with reference to the illustrations in fig. 1 and 2 is a device 1 for removable material M in the form of an applicator stick.

The device 1, as shown in particular in fig. 2, is essentially composed of a material carrier 2, a protective cap 4 which shapes the mating holding cylinder 3, and a movement element 5.

The movement element 5 has a longitudinal slot 6 in which a pin 7 of the material carrier 2 is guided, wherein the longitudinal slot 6 is formed by a movement section 8 which extends in the same direction as the longitudinal axis x of the device 1 and a holding section 9 which extends at an angle or at an angle to the longitudinal axis.

Furthermore, the components of the device 1, which according to the figures may be designed as a lipstick, may be a cap-shaped outer cover 10 for the protective covering of the material M in the non-use state retracted into the retracted position according to fig. 1.

As also shown, the device 1 may be generally shaped as a rotationally symmetric cylinder, having a longitudinal axis x forming the axis of rotation. The longitudinal extent in the axial direction can correspond to approximately 3 to 5 times, in particular approximately 4 times, the outer diameter dimension viewed transversely to the longitudinal axis x.

All components of the device 1 are preferably made of plastic, in particular of the same plastic, in particular hard plastic, which are further produced, for example, in a plastic injection molding process in each case. Thus, all components of the device 1 may be made of polypropylene, for example.

The movement element 5, which is also shown in a separate illustration in fig. 3 to 6, is essentially composed of segments arranged one behind the other in the axial direction, which preferably can also be designed in one piece and are joined together in a material-consistent manner. In the exemplary embodiment shown, therefore, a cylindrically shaped actuating section 11 is first obtained. The actuating section may have an outer diameter matching the outer diameter of the outer jacket element 10 and extend in the axial direction over approximately a quarter of the entire length of the device 1.

The actuating section 11 can be stepped into a neck ring section 12 of smaller diameter than the actuating section 11. It is also preferred that the outer diameter of the neck ring section can be matched to the inner diameter of the outer shell part 10, so that the outer shell part placed can bear on the end side on the step created between the handling section 11 and the neck ring section 12 in a preferred design.

In the device-closing position, the friction protrusions 13 provided on the outside of the wall of the neck ring section 12 interact with the inner surface of the wall of the outer cover piece 10. Thus, in the device-closed position, a frictional contact is produced, which must be overcome before the cover element 10 can be removed.

Furthermore, a tubular guide section 14, the outer diameter of which is preferably selected to be smaller than the outer diameter of the neck ring section 12, axially abuts on the neck ring section 12.

The outer diameter of the guiding section 14 is substantially matched in size to the inner diameter of the mover 5, wherein the outer diameter of the mover 5 is further yet preferably matched to the outer diameter of the neck ring section 12. A step arranged between the neck ring section 12 and the guide section 14 can thus be produced, on the circumferential and free end face of which the generally sleeve-shaped movement part 5 can be supported.

In the region of the free end facing away from the actuating section 11, the guide section 14 can carry a radially outwardly projecting circumferential retaining collar 15, which preferably has an outer diameter matching the outer diameter of the mating retaining sleeve 3.

Thus, the cooperative holding cartridge 3 can be held between the holding neck ring 15 and the neck ring section 12 in a substantially non-displaceable manner in the axial direction, wherein the cooperative holding cartridge 3 is preferably freely rotatable relative to the mover 5 about the longitudinal axis x.

Two longitudinal slots 6, 6' are provided in the guide section 14, which are diagonally or diametrically opposite with respect to the longitudinal axis x. The two longitudinal slots extend substantially at least with the movement section 8 oriented with the longitudinal axis x.

The moving portion 8 is respectively transferred into the holding portions 9 and 16 at the end, wherein, according to the enlarged detail illustrations in fig. 3 and 6, the central longitudinal axis y of such a holding portion 9 or 16 can enclose an obtuse angle α of approximately 110 to 115 degrees with respect to the central longitudinal axis z of the moving portion 8.

Referring to the top view of the device 1, in which the longitudinal axis x is shown as a point, the retaining sections 9 of the longitudinal slots 6 and 6', which correspond to the free ends of the guide sections 14, can be arranged to point in a clockwise direction, while the retaining sections 16, which correspond to the ends of the guide sections 14 facing the neck ring section 12, can be arranged to point in a counterclockwise direction.

Furthermore, in the illustrated side views according to fig. 3 and 6, the free end of the guide section 14 is bent upwardly in the direction of the free end, while the lower holding section 16 extends bent downwardly in the direction of the neck ring section 12.

The upper holding section 9, which defines the maximum projecting position of the material carrier 2, can end at an axial distance from the free end of the movement 5 or the holding collar 15, while the lower holding section 16, which defines the retracted position, can end essentially in the transition to the collar section 12, if necessary into the step plane.

The covering wall of the guide section 14 can have hole-like perforations 17 offset in the circumferential direction relative to the respective end regions of the holding sections 9 and 16. These perforations may be provided for improving the release of the moving part 5 during the manufacturing process, preferably in a plastic injection molding process.

As can be seen in particular from the illustration in fig. 3, the longitudinal slot 6' extends beyond the region into the upper retaining section 9, preferably up to the retaining collar 15, while the moving section 8 of the longitudinal slot 6 transitions into the retaining section 9 according to the illustration in fig. 6.

In the region of the elongated longitudinal slot 6', the retaining collars 15 can be separated by radial separating portions 18 to facilitate assembly of the material carrier 2.

In fig. 7 to 13, the piston-like active material carrier 2 is shown in a separate illustration.

The material carrier 2 has first and essentially a circumferential carrier wall 19 and a carrier bottom 20 which is set back transversely to the carrier wall. In the usual operating position, for example according to fig. 17, the material carrier 2 has an upwardly open pot opening 21 delimited by a carrier wall 19 and a carrier bottom 20. The material M, for example in the form of a lip balm, is accommodated in this pot-shaped section of the material carrier 2 on the foot side.

For the positive connection of the material M to the material carrier 2, a plurality of ribs 22 which are uniformly distributed over the circumference and point radially inward can be formed on the tank interior, in particular on the wall interior of the carrier wall 19. On the basis of the cross section transverse to the longitudinal axis x according to fig. 13, the bead is formed in a blade-like manner, tapering radially inward from the inner wall surface, as is also shown according to the enlarged detail in fig. 13.

According to the embodiment shown, eight such ribs 22 may be provided distributed over the circumference.

The bead 22 extends axially from the carrier base 20 and, according to the illustration in fig. 12, terminates at a distance from the free edge of the can mouth 21.

The carrier wall 19 extends further on the underside of the carrier bottom 20, for example with an axial length which may correspond to about half or one third of the axial length of the carrier wall 19, to form a tank containing the material M.

As can be seen in particular from the illustrations in fig. 7 to 10, the carrier wall 19 can be provided in the section extending on the underside of the carrier base 20 not necessarily completely encircling. Thus, according to the embodiment shown, two wall sections 23 can be provided which have different circumferential extensions when viewed circumferentially.

As also shown, a friction cam 24 protruding in the radial direction may be formed on the wall outside of the wall section 23. In general, three such friction cams 24 can be arranged distributed over the circumference.

According to the illustration in fig. 8 or 10, each friction cam 24 can have, with reference to the radially outer view, a substantially drop-shaped edge, i.e. a drop-shaped contour 25, which has a longer dimension a and a shorter dimension b, wherein the longer dimension a extends substantially in the direction of the longitudinal axis x and thus in the direction of the movement section 8 of the longitudinal slot 6 and 6'. The shorter dimension b may extend perpendicularly to the longer dimension, further preferably substantially in the circumferential direction.

Furthermore, the maximum dimension of the friction cam 24 along the line u extending in the circumferential direction can extend here eccentrically to the center line w, further preferably illustrated below with reference, i.e. extending correspondingly away from the material M to be contained, which is based on the maximum dimension of the line v in the longitudinal direction (see in particular the enlarged illustration in fig. 8).

As can be seen in particular from the enlarged illustration in fig. 12, the drop-shaped friction cam 24 is also formed in the case of the outward radial projection. With reference to the vertical sectional illustration according to fig. 12, the friction cam 24 is essentially bellied with a radially outer inflection point approximately in the region of the line u representing the maximum dimension in the transverse direction.

The maximum radial extent c of such a friction cam 24 may correspond to approximately one third to one quarter of the maximum extent of the friction cam 24 in the circumferential direction along the line u.

Furthermore, two pins 7 arranged diagonally or diametrically opposite one another are provided on the wall outer side of the carrier wall 19 approximately at the axial height of the carrier base 20. As shown, this may involve a pin 7 made of a substantially cylindrical solid material.

It is also preferred that the diameter of the pin 7 can be adapted to the clear distance, viewed in the circumferential direction, of the edges of the movement sections 8 of the longitudinal slots 6 and 6' pointing towards one another.

Furthermore, the holding sections 9 and 16 are also adapted to this distance, so that the pin 7 is also reliably guided in the region of the holding sections 9 and 16 when the material carrier 2 is displaced accordingly.

The co-operating retaining cylinder 3 is provided with two control grooves 26 on the inside of the wall, which are designed to be offset from each other by 180 degrees with respect to the cylinder axis x and to rise threadlike along the coated inner wall. According to the embodiment shown, these two-channel extending control grooves 26 can extend with a preferably constant slope about 2.5 turns starting from the end of the mating holding cylinder 3 facing the neck ring section 12 in the direction of the end covered by the holding neck ring 15.

The control recess 26 can here open freely into the end face of the mating holding cylinder 3, which is optionally supported on the neck-ring section 12, while the end facing away from this preferably ends at a distance from the end of the mating holding cylinder 3 on the holding neck-ring side.

As can be seen in particular from the illustrations in fig. 15 and 16, the control groove ends, which are designed at a distance from the end region of the mating holding cylinder 3, can also preferably merge into an inclined surface 27 on the end side, which, if necessary, reduces the groove depth uniformly, ultimately transforms into the inner surface 28 of the mating holding cylinder 3.

The material carrier 2 is arranged in the device 1 in such a way that it is surrounded not only by the guide section 14 of the movement element 5 but also by the mating holding cylinder 3, which at the same time surrounds the guide section 14.

The pins 7 of the material carrier 2 pass through the longitudinal slots 6 and 6' of the movement element 5 and are sunk with their radially outer end sections into the control recesses 26 of the mating retaining cylinder 3.

The friction cam 24 is in frictional contact with an inner surface 29 of the movement element 5 or of the guide section 14.

Due to this arrangement, by holding the device 1 on the co-operating holding cylinder 3 and by rotating the movement section 8 in the region of the handling section 11 by gripping, a relative rotational displacement between the co-operating holding cylinder 3 and the movement element 5 can be achieved, so that the material carrier 2 can be moved by the pin 7 in the direction of extension of the longitudinal axis x via the control groove 26 of the co-operating holding cylinder 3 along the longitudinal slits 6 and 6'.

Fig. 17 to 24 show the lowermost, respectively maximum retracted position of the material carrier 2, and also the material M carried by the material carrier 2.

As can be seen in particular from the sectional illustration in fig. 24, the material carrier 2 is supported here by its pins 7 on the base of the lower holding section 16, which defines the retracted position, if appropriate directly on the step formed between the neck ring section 12 and the guide section 14, into which the base of the holding section 16 can merge.

The maximum retracted position may be designed such that it can be passed over against the usual direction of rotation for displacing the material carrier 2 in the direction of the extended position. This effect can be supported by a control groove 26 which terminates edgeless freely to said end of the mating holder cartridge 3.

Furthermore, the position of the pin 7 in the lower holding section 16 is also shown by way of example in fig. 18 and 21. It can also be seen that at least one retaining section 16 of the longitudinal slot (here the longitudinal slot 6') has a locking projection 30, over which the pin 7 can pass. The locking projection 30 may form a narrowing of the free passage dimension of the retaining section 16.

The passage dimension d of the retaining section 16 reduced by the locking projection 30 may correspond to approximately 0.9 to 0.95 times the diameter dimension e of the pin 7 (see fig. 18).

Fig. 19 shows an intermediate position during the passage of the locking projection 30 over the pin 7. It is only possible to intentionally roll over the locking projection 30 by a relative rotational displacement caused by the user accordingly. Since the parts are formed of a resilient plastics material, overriding of the locking projections 30 is achieved.

In the embodiment shown, the retaining section 16 of the further longitudinal slot 6 does not have such a locking projection 30. However, it is also conceivable in this respect to form the locking projections 30 in the region of both lower retaining sections 16.

In the event of a turning over of the locking projection 30, the material carrier 2 leaves the retracted position and is gradually moved axially forward via the movement sections 8 of the longitudinal slits 6 and 6' as a result of the relative rotational displacement between the mobile element 5 and the mating holding cylinder 3, in order to displace the material M outwardly through the free end of the mating holding cylinder 3 and the mobile element 5 which is designed to be open.

The maximum possible extended position is shown in fig. 26 to 32. After passing through the movement section 8 of the two longitudinal slots 6 and 6', the pin 7 is brought into the holding section 9, which is arranged at an obtuse angle to the movement section. In this case, the material carrier 2 performs a rotational movement of a few degrees, for example about 10 degrees, about the longitudinal axis x together with the contained material M, also when leaving the retracted position.

The maximum extended position is defined by a stop limit in the holding section 9. The maximum extended position can also be designed as preferably not to be overridden. The respective pin 7 can thus be clamped between the control recess 26 and the edges of the retaining section 9 which point toward one another.

As can be seen in particular from the illustration in fig. 29, the maximum projecting position can also be ensured by a further locking projection 31. According to the embodiment shown, such a locking projection 31 can be provided in the retaining section 9, here preferably in the retaining section 9 of the longitudinal slit 6. In the illustrated embodiment, the retaining section 9 of the further longitudinal slot 6' is not provided with such a latching projection 31, although this is possible in a further embodiment.

The locking projection 31 can be designed essentially identically to the locking projection 30 in the region of the lower retaining section 16. In this connection, therefore, the same ratio between the waisted channel dimension d in the region of the retaining section 9 due to the locking projection 31 and the diameter e of the pin 7 can be achieved.

Fig. 30 shows a state where the locking projection 31 is passed over by the pin 7. Accordingly, the cancellation of the maximum extended position can only be intentionally cancelled by a relative rotation with intervention on the part of the user.
