Definitions
- the present invention relates to a deodorant dispenser, a refill pack for such a deodorant dispenser, a deodorant dispenser system consisting of at least one such deodorant dispenser and at least one such refill pack, a method for filling such a deodorant dispenser with a deodorant -Mass and a method for refilling such a deodorant dispenser with a refill pack.
- deodorant dispensers considered here which are filled with a firm but soft deodorant mass to be applied to the skin, are also referred to as deodorant sticks or deodorant sticks.
- deodorant dispensers Due to their mechanical function, the deodorant dispensers currently on the market are complex mechanical systems that usually have between four and eight components. Due to this large number of different components, the relaunch of a deodorant dispenser poses major costs and logistical problems for companies in the cosmetics industry. Accordingly, deodorant dispensers are revised less often than is the case, for example, with packaging that only consists of a container and a closure. Deodorant dispensers therefore often remain geometrically unchanged on the market for ten or more years.
- deodorant dispensers are mostly made of plastic.
- plastic packaging is currently being questioned for ecological reasons. There is therefore a great need for multiple use of deodorant dispensers by means of a refill (so-called “refill options”).
- US 2020/0054110 A1 describes a deodorant delivery system which comprises a reusable housing with a body and a rotary knob which is rotatably connected to the body.
- the body is structured in such a way that it contains an exchangeable deodorant cartridge with a sleeve and a rod made of a deodorant mass inserted therein.
- the object of the present invention is to provide an improved refillable deodorant dispenser and an associated refill pack.
- a deodorant dispenser according to claim 1
- a refill pack for such a deodorant dispenser according to claim 14 Deodorant dispenser system according to claim 26, a method for filling such a deodorant dispenser with a deodorant mass according to claim 28, a method for filling such a refill pack with a deodorant mass according to claim 29, a use of a filling device for deodorant Composition according to claim 30 and a method for refilling such a deodorant dispenser achieved by a refill pack according to claim 31 or 32.
- Advantageous embodiments and developments of the invention are the subject of the subclaims.
- bottom and top always refer to a position of the deodorant dispenser or the refill pack in which the deodorant mass can be removed from the upper end of the deodorant dispenser or the refill pack. This position usually also corresponds to the storage and use position of the deodorant dispenser.
- a first aspect of the invention relates to a deodorant dispenser with a container which has a wall enclosing an interior of the container, and a rotating body which is rotatably connected to the container and which has a first coupling for the rotationally fixed, form-fitting, releasable connection in the interior of the Has container with a second coupling, wherein in the deodorant dispenser at least one continuous, closable opening is formed from a lower outside of the deodorant dispenser to an upper end of the interior of the container.
- the deodorant mass preferably has a firm but soft consistency which can be transferred to the skin by rubbing it.
- the deodorant dispenser can be filled with the deodorant mass through the continuous, closable opening.
- the deodorant mass is usually heated before filling, thereby liquefying it and pouring it into the deodorant dispenser as a liquid. After cooling down, the deodorant mass is then given its firm consistency.
- This filling is preferably carried out as an initial filling during the manufacturing process of the deodorant dispenser in a filling system.
- the production can also be divided between different companies, in particular the production of the deodorant dispenser itself at a plastics processing company and the filling at a cosmetics manufacturer or in each case with a subcontractor of one of these companies.
- the continuous, closable opening preferably runs through the first coupling of the rotating body.
- the deodorant dispenser can be coupled to an elevator and a spindle, which can transport a deodorant mass upwards.
- the container of the deodorant dispenser is preferably open at the top.
- the container further preferably has a removable closure, in particular a cap, which closes the upper, open end of the container and which can be removed by the user in order to open the container at its upper end. In this way, the deodorant mass can be removed from the upper end of the container and further deodorant mass can be transported upwards.
- the spindle and the elevator can be removed after the deodorant mass has been completely used up and replaced by a refill pack after it has been ejected. This means that the deodorant dispenser can be used several times, which saves material.
- the possibility of both an initial filling and a refill of the deodorant dispenser enables the manufacturer to offer the deodorant dispenser either as a first filling and not intended for refilling, as a first filled and refillable or as an empty and refillable deodorant dispenser without different Having to develop deodorant dispensers. In this way, the manufacturer can react flexibly to customer requests.
- the ability to fill it for the first time also enables the user to use the deodorant dispenser immediately after purchase, without having to deal with the refill technique. Only after the first filling has been used up, when the user is already familiar with its function from having used the deodorant dispenser for a long time, does he have to purchase a refill pack and deal with the steps required to insert the refill pack. This makes the deodorant dispenser easier and more convenient for the user to use.
- the container has at least one first sealing element, in particular a cylindrical seal or an elastomer seal, in particular a rubber seal, which seals an area between the container and the rotating body. This ensures that the durability of the deodorant mass is increased in that it does not dry out and / or no substances evaporate from it, but the rotating body nevertheless remains rotatable relative to the container.
- the first coupling has at least one first latching element for latching with a second latching element of the second coupling and thus for producing a non-rotatable, form-fitting connection between the first coupling and the second coupling.
- the first coupling also has at least one first separating element for interacting with a second separating element of the second coupling and thus for releasing the first latching element and the second latching element and for releasing the non-rotatable, form-fitting connection of the first coupling with the second coupling.
- an empty deodorant dispenser can preferably be implemented using the embodiments described so far, the embodiments described below correspond to a deodorant dispenser that has been filled for the first time.
- the deodorant dispenser also has a spindle with a second coupling, which is non-rotatably and positively connected to the first coupling.
- the spindle has an external thread and is arranged inside the container and essentially parallel to its longitudinal axis.
- the deodorant dispenser also has an elevator which extends inside the container essentially in at least one direction orthogonal to the spindle and which cannot be rotated relative to the wall of the container. This has an internal thread in which the external thread of the spindle runs.
- the above-mentioned at least one through opening in the deodorant dispenser extends from the lower outside of the deodorant dispenser through the elevator or past the elevator to the upper end of the interior of the container.
- the deodorant dispenser can be filled with the, preferably liquefied, deodorant mass from below through this opening.
- the deodorant mass then preferably hardens and adheres to the elevator. This is also preferably done by a combination of form fit and material fit, in that the deodorant mass penetrates into recesses in the elevator and adheres there.
- the continuous, closable opening preferably runs through the first coupling of the rotating body and through the second coupling of the spindle.
- the container, the rotating body, the spindle and the elevator are connected to one another in such a way that rotating the rotating body leads to a common rotation of the first and second coupling and thus also of the spindle in an ascent direction or in a descent direction through which the elevator - and thus the entire deodorant mass - is moved upwards or downwards, and that a rotation of the rotating body, preferably in the descent direction, more preferably in the ascent direction, when the elevator is in an end position at an upper end of the spindle , leads to the disconnection of the connection between the first clutch and the second clutch.
- the deodorant dispenser can be filled with the deodorant mass on the one hand in the assembled state through the opening which extends from the lower outside of the deodorant dispenser through the elevator and on the other hand it can be filled with the deodorant after the deodorant has been used up -Mass allows to eject the spindle, the second clutch and the elevator, which prepares the deodorant dispenser to be refilled with a refill pack.
- the spindle preferably at its lower end, has a first latching means and the elevator, preferably at its lower end, has a second latching means, the elevator being set up to allow the rotating body to rotate in the descent direction, until the elevator is in an end position at a lower end of the spindle, leads to the locking of the first locking element with the second locking element.
- the first locking means is preferably a recess in an upper surface of a flange-like widening at the lower end of the spindle.
- the second locking means is preferably a corresponding projection on the lower end of the elevator. In a specific rotational position of the elevator with respect to the spindle, when the elevator is at the lower end of the spindle, the projection on the elevator can snap into the recess in the spindle.
- the spindle has a blocking area at its upper end, in which the elevator can be blocked in the end position at the upper end of the spindle. “Blockable” is intended to mean that the elevator cannot be rotated with respect to the spindle.
- the elevator is preferably blocked by striking a stop in the blocking area of the spindle.
- the elevator can also be locked in the blocking area. If, however, the elevator only runs against a stop, it can be turned back again without any effort when this stop is reached, without having to overcome a latching resistance.
- the second coupling has at least one second latching element, which is latched with the first latching element of the first coupling, so that the first coupling is non-rotatably and positively connected to the second coupling. Furthermore, the second coupling has at least one second separating element for interacting with the first separating element of the first coupling and, when the elevator is in the end position at the upper end of the spindle, for unlocking the first latching element and the second latching element and for releasing the non-rotatable ones , positive connection of the first clutch with the second clutch.
- the at least one first separating element and the at least one second separating element together form a wedge gear.
- the first and the second separating element preferably each have an inclined surface, which bear against one another and can be displaced against one another, in particular by a rotary movement.
- a wedge gear has the advantage that it converts a rotary movement into a rotary and a linear movement of the second separating element away from the first separating element can be converted. As a result, the form fit is canceled and the second clutch is separated from the first clutch.
- the at least one first separating element and the at least one second separating element each have at least six, preferably at least eight, more preferably at least twelve inclined surfaces. This has the advantage that the first and the second separating element do not have to be aligned with one another as precisely when they are assembled.
- the at least one first separating element and the at least one second separating element together form a bayonet lock.
- a bayonet lock is usually understood to mean a lock which is closed by a straight movement and a subsequent rotary movement, with a latching preferably occurring at the end of the rotary movement and which can be opened again by movements in the reverse order.
- a bayonet lock can also be designed in such a way that the lowering plate can easily determine whether the connection can be released by rotating the rotating body in the ascent direction and / or in the descent direction.
- the elevator and the spindle are designed so that the elevator at least partially emerges from the container after reaching the upper end of the container and a further rotation of the spindle leads to a rotation of the elevator relative to the container.
- the elevator when it has at least partially emerged from the container, is set up so that after a further rotation of the elevator relative to the container by a certain angle, the elevator is blocked relative to the container.
- the blocking is preferably done by a corresponding shaping of the elevator and / or the container, which enter into a form fit after further rotation through a certain angle.
- the deodorant dispenser also has a deodorant mass which at least partially fills the interior of the container. This corresponds to a deodorant dispenser with an initial filling. In this state, the deodorant dispenser can be sold as a product that can be used immediately, regardless of whether it is intended for a refill or not.
- a second aspect of the invention relates to a refill pack for a deodorant dispenser according to one of the mentioned embodiments with a refill container which has a wall enclosing an interior of the refill container, a refill spindle with a second coupling which rotatably and positively interlocks with the first coupling of the container Deodorant dispenser can be connected, wherein the refill spindle has an external thread and wherein the refill spindle is arranged inside the refill container and essentially parallel to its longitudinal axis, and a refill elevator which extends inside the refill container essentially in at least one direction orthogonal to the refill spindle and is not rotatable with respect to the wall of the refill container and which has an internal thread in which the external thread of the refill spindle runs.
- At least one continuous, closable opening is formed from a lower outer side of the refill pack to an upper end of the interior of the refill container.
- the continuous, closable opening preferably runs through the second coupling of the refill spindle.
- the refill container can be inserted into the container of the deodorant dispenser by a straight movement in such a way that the first coupling of the rotating body of the deodorant dispenser is rotatably and positively connected to the second coupling of the refill spindle and that then the container of the deodorant dispenser, the refill container, the rotary body, the refill spindle and the refill elevator are connected to one another in such a way that a rotation of the rotary body leads to a common rotation of the first coupling of the rotary body of the deodorant dispenser and the second coupling of the refill spindle and thus also the refill spindle in an ascent direction or in a descent direction, through which the refill elevator is moved upwards or downwards, and that a turning of the rotating body, preferably in the descent direction, continues preferably in the ascent direction, when the refill elevator is in an end position at an upper end of the refill spindle, leads to the disconnection of the first coupling of the rotary body of the deodorant dispenser with the second coupling of the refill spindle.
- the refill pack After the refill pack has been introduced into the deodorant dispenser, from the user's point of view it behaves like an already filled deodorant dispenser according to one of the above-mentioned embodiments.
- Such a refill pack makes it possible to use a deodorant dispenser for several fillings of the deodorant mass, which saves material and costs and meets the increasing need for environmentally friendly packaging concepts.
- the second coupling has at least one second sealing element, in particular a lamellar seal or an elastomer seal, in particular a rubber seal, which seals an area between the second coupling and the refill container.
- the second sealing element is preferably designed in one piece with the second coupling, in particular as a single injection-molded part made of plastic.
- the second sealing element particularly preferably forms a component that is separate from the second coupling. In the latter case, a mono-material solution is preferred for recycling reasons; H. the second coupling and the second sealing element separate from it are made of the same material; however, a combination of different materials can also be used.
- the second sealing element ensures that the durability of the deodorant mass is increased in that it does not dry out and / or no substances evaporate from it as long as the refill pack has not yet been inserted into the container.
- the second coupling is designed such that the first coupling of the rotating body of the deodorant dispenser can be connected to the second coupling in a rotationally fixed and form-fitting manner in every rotational position of the second coupling.
- the refill spindle has a first latching means, preferably at its lower end, and the refill elevator, preferably at its lower end, a second latching means, the refill elevator being set up so that the rotating body of the deodorant dispenser can rotate in the descent direction, until the refill elevator is in an end position at a lower end of the refill spindle, leads to the locking of the first locking element with the second locking element.
- the first locking means is preferably a recess in an upper surface of a flange-like widening at the lower end of the refill spindle.
- the second locking means is preferably a corresponding projection at the lower end of the refill elevator. In a certain rotational position of the refill elevator with respect to the refill spindle, when the refill elevator is at the lower end of the refill spindle, the projection on the refill elevator can snap into the recess in the refill spindle.
- the refill spindle has a blocking area at its upper end, in which the refill elevator can be blocked in the end position at the upper end of the spindle.
- the second coupling has at least one second latching element which can be latched to a first latching element of the first coupling of the rotating body of the deodorant dispenser, so that the first coupling rotates with the second coupling and is positively connected.
- the second coupling has at least one second separating element for interacting with a first separating element of the first coupling of the deodorant dispenser and, when the refill elevator is in the end position at the upper end of the refill spindle, for unlocking the first latching element and the second latching element and for releasing the non-rotatable, form-fitting connection between the first coupling and the second coupling.
- the at least one second separating element is designed to form a wedge gear together with the at least one first separating element of the first coupling of the deodorant dispenser.
- the at least one second separating element has at least six, preferably at least eight, more preferably at least twelve inclined surfaces.
- the at least one second separating element is designed to form a bayonet lock together with the at least one first separating element of the first coupling of the deodorant dispenser.
- the refill elevator and the refill spindle are designed so that the refill elevator at least partially exits the refill container after reaching the upper end of the refill container and a further rotation of the refill spindle leads to a rotation of the refill elevator relative to the refill container.
- the refill elevator when it has at least partially emerged from the refill container, is set up so that after a further rotation of the refill elevator relative to the refill container by a certain angle, the refill elevator is blocked relative to the refill container.
- the blocking preferably takes place through a corresponding shape of the refill elevator and / or the refill container, which form a form fit after further rotation through a certain angle.
- the refill pack also has a deodorant mass which at least partially fills the interior of the refill container. This corresponds to a refill pack with one filling.
- the refill pack can be sold as a product which can be used in connection with a deodorant dispenser according to the invention, specifically individually or in combination with such a deodorant dispenser.
- a third aspect of the invention relates to a deodorant dispenser system consisting of at least one deodorant dispenser according to the first aspect of the invention and at least one refill pack according to the second aspect of the invention.
- the deodorant dispenser is a deodorant dispenser that has a spindle and an elevator, wherein the spindle of the deodorant dispenser and the refill spindle of the at least one refill pack are identical and / or the elevator of the deodorant dispenser and the refill elevator of the at least one refill pack are identical or identical apart from slightly different external dimensions.
- the partly identical components mean that the costs for multiple development and multiple production of injection molds for different spindles or elevators can be saved.
- a slight change in the external dimensions of the refill elevator compared to the elevator may be necessary, since the internal dimensions of the refill container of the refill pack are somewhat smaller than the internal dimensions of the container of the deodorant dispenser, because the former must be able to be used in the latter.
- the elevator and the refill elevator are constructed identically, in particular with the slightly smaller external dimensions for the refill elevator, there is a gap between the outside of the elevator and the inside of the container of the deodorant dispenser, whereby the deodorant mass adheres to the inside of the container could, especially in the case of deodorant compositions with low viscosity. This can be prevented by the slightly different outer dimensions of the elevator and the refill elevator.
- a fourth aspect of the invention relates to a method for filling a deodorant dispenser according to the first aspect of the invention, which already has a spindle and an elevator, but not yet has a deodorant mass, with a deodorant mass with the steps:
- a fifth aspect of the invention relates to a method for filling a refill pack according to the second aspect of the invention, which does not yet have a deodorant mass, with a deodorant mass with the steps:
- the method for filling the refill pack according to the invention thus runs entirely analogously to the method according to the fourth aspect of the invention for filling a deodorant dispenser according to the invention (i.e. for the first filling of the deodorant dispenser).
- the filling device can be a conventional filling device for deodorant mass.
- a sixth aspect of the invention therefore relates to the use of a filling device for deodorant mass, with at least one deodorant dispenser according to the first aspect of the invention and at least one refill pack according to the second aspect of the invention on the filling device in any order, both of which are not yet included Deodorant mass are filled, are filled in a method according to the fourth or fifth aspect of the invention.
- the Filling device can be used without significant changes both for filling a deodorant dispenser according to the invention and for filling a refill pack according to the invention, in any order.
- a seventh aspect of the invention relates to a method for refilling a deodorant dispenser according to the first aspect of the invention, which does not yet have a spindle, no elevator and no deodorant mass, by a refill pack according to the second aspect of the invention with the step:
- Refilling is particularly user-friendly thanks to a straight insertion movement. This reduces the risk of incorrect insertion and damage to the material.
- An eighth aspect of the invention relates to a method for refilling a deodorant dispenser according to the first aspect of the invention, which already has a spindle and an elevator, by a refill pack according to the second aspect of the invention with the steps:
- Rotating the rotating body of the deodorant dispenser preferably in the descent direction, more preferably in the ascent direction, and thereby disengaging the connection of the first coupling of the rotating body to the second coupling of the spindle;
- the described aspects of the invention lead to the manufacturer's desired flexibility in being able to offer the deodorant dispenser according to the invention either as a first-filled and not intended for refilling, as a first-filled and refillable or as an empty and refillable deodorant dispenser.
- the latter could, for example, take the form of a “starter kit” consisting of an empty deodorant dispenser and a refill pack.
- starter kit consisting of an empty deodorant dispenser and a refill pack.

- FIG. 1a and 1b show schematically a deodorant dispenser according to the invention, FIG. 1a showing a deodorant dispenser filled with deodorant mass 50 and FIG. 1b showing a schematic view of an empty deodorant dispenser obliquely from below.
- a container 10 with a closure 11 on the underside of which a rotating body 20 is rotatably attached, the connection area being sealed by a first sealing element 12, a cylinder seal. This prevents the deodorant mass 50 in the container 10 from drying out.
- the first coupling 21 Located on the rotating body 20 is the first coupling 21, which is integrally connected to the rotating body 20 and which is connected to the second coupling 31 in a rotationally fixed and form-fitting manner.
- a spindle 32 with an external thread 33 is attached in one piece to the second coupling 31.
- An elevator 40 is located orthogonally to the spindle 32, in the internal thread 43 of which the external thread 33 of the spindle 32 engages.
- the deodorant mass 50 which is carried by the elevator 40, is located above the elevator 40. Rotation of the rotating body 20 is transmitted to the spindle 32 via the first coupling 21 and the second coupling 31. This results in an upward or downward movement of the elevator 40 and thus of the deodorant mass 50.
- a multi-piece design of the rotating body 20 and the first coupling 21 or the spindle 32 and the second coupling 31 is of course also conceivable.
- the deodorant dispenser in the figures has a container 10 and an elevator 40, each of which has a non-round, but for example oval or lens-shaped cross-section (see in particular FIG Container 10 is not rotatable relative to this. However, this is not a limitation of the invention.
- the deodorant dispenser can also have a container 10 and an elevator 40 with a round cross-section. Additional elements must then be provided in order to prevent the elevator 40 from rotating within the container 10, for example radial projections on the outside of the elevator 40 which run in corresponding axial grooves in the inside of the container 10.
- the container 10 For the first filling, the container 10 is turned over and a liquefied deodorant mass 50 flows through the coupling opening 22 in the first coupling 21 and the elevator opening 42 in the elevator 40 into the container 10 onto the deodorant cover, which is located at the upper end of the container 10 (ie below in the position shown in FIG. 1b).
- the container 10 is filled with the deodorant mass 50 until it reaches the elevator 40 and also passes through the elevator opening 42.
- the coupling opening 22 is then closed by a plug 23.
- the plug 23 can in particular consist of a rigid plastic element or also of a film.
- FIG. 2a and 2b schematically show a refill pack according to the invention, FIG. 2a showing a refill pack filled with deodorant mass 50 and FIG. 2b showing a schematic view of an empty deodorant dispenser obliquely from below.
- a refill container 10 'with a deodorant cover 51 and a closure 11 is shown.
- the refill container 10' is preferably thin-walled (for example with the wall thickness of a yogurt cup) and thus light and saves material.
- the deodorant cover 51 can in particular consist of a rigid plastic element or also of a film.
- the second coupling 31, which is rotatably connected to the refill container 10 ', is located at the lower end, the connection area between the second coupling 31 and the refill container 10' being sealed by a second sealing element 13, a lamellar seal. This prevents the deodorant mass 50 in the refill container 10 'from drying out.
- a refill spindle 32 with an external thread 33 is attached in one piece to the second coupling 31, and a refill elevator 40 is located orthogonally to the refill spindle 32, which via an internal thread 43 with the external thread 33 of the Refill spindle 32 is connected.
- the refill elevator 40 Due to the thin walls of the refill container 10 ', it is possible to design the refill elevator 40 with the same outside diameter as an elevator 40 for a first-filled deodorant dispenser, in particular even structurally identical to this, since the inside diameter of the container 10 of the deodorant dispenser and the The inner diameter of the refill container 10 'differ only slightly.
- the deodorant mass 50 which is carried by the refill elevator 40, is located above the refill elevator 40 in FIG. 2a. Rotation of the second coupling 31 is transmitted to the refill spindle 32. This results in an upward or downward movement of the refill elevator 40 and thus of the deodorant mass 50.
- a multi-piece design of the refill spindle 32 and the second coupling 31 is conceivable.
- the refill container 10 ' For filling, the refill container 10 'is turned over, and a liquefied deodorant mass 50 flows through the coupling opening 22 and the elevator opening 42 into the refill container 10' onto the deodorant cover, which is located at the upper end of the refill container 10 '(in the in Fig. 2b is the position shown below).
- the refill container 10 ' is filled with the deodorant mass 50 until it reaches the elevator 40 and also passes through the elevator opening 42.
- the coupling opening 22 is closed by a plug 23 ‘.
- the plug 23 ‘ can in particular consist of a rigid plastic element or also of a film.
- 3a-d schematically show a cross section of a filled deodorant dispenser according to the invention through a plane which contains the vertical container axis, in different states.
- FIG. 3a shows the deodorant dispenser in the state of use partially filled with a deodorant mass 50.
- the rotating body 20 is rotated in the ascending direction, as a result of which the elevator 40 transports the deodorant mass 50 upwards.
- 3b shows the deodorant dispenser after the deodorant mass 50 has been used up and the elevator 40 has been blocked at the upper end of the spindle 32 at the blocking area 34. Because the elevator 40 is blocked, a further rotation of the rotating body 20 does not result in an upward or downward movement of the elevator 40, but rather exerts a force between the first coupling 21 and the second clutch 31, which is used to release the form fit of the first clutch 21 with the second clutch 31.
- the spindle 32 and the elevator 40 should be designed in such a way that they withstand the force mentioned, which in particular represents a torsional force, without any appreciable deformation, since such deformation leads to a malfunction when the form fit between the first coupling 21 and the second is released Coupling 31 could lead.
- 3c shows the deodorant dispenser after the form fit between the first coupling 21 and the second coupling 31 has been released.
- the second coupling 31, the spindle 32 and the elevator 34 connected to it can be removed together from the container 10 and can be recycled.
- FIG. 3d shows the deodorant dispenser after the second coupling 31, the spindle 32 and the elevator 34 connected to it have been removed from the container 10 and while a refill pack is then inserted.
- the refill container 10 ‘is inserted in a straight line into the container 10 until the second coupling 31 of the refill pack engages positively in the first coupling 21 of the deodorant dispenser.
- the deodorant cover 51 is then removed and the deodorant dispenser can continue to be used in the same way as after the initial filling.
- a removal flange 14 which has a slightly larger diameter than the refill container 10' and which protrudes upwards for the user to grasp when the form fit between the first coupling 21 and the second coupling 31 is released Removal of the refill container 10 'from the container 10 is facilitated.
- FIG. 4a-c show a cross section of the lower part of the deodorant dispenser, the rotating body 20 and the two couplings 21, 31 through a plane which contains the vertical container axis when the form fit of the two couplings 21, 31 is released.
- FIG. 4a shows the first coupling 21 with an existing form fit with the second coupling 31.
- the first coupling 21 has a first latching element 25 which is implemented by a window in the side wall of the first coupling.
- the second latching element 35 which is integrally connected to the second coupling 31, sits in this window. Since the second latching element 35 nearly closes the window fills, there is a non-rotatable and form-fitting connection. To release this form fit, a force is required that the material of the first clutch
- first coupling 21 deformed in the area of the first latching element 25 in such a way that the form fit is released. Furthermore, the first coupling 21 has a first separating element 26 in the form of an inclined surface, which engages with a second separating element 36 of the second coupling, which is also an inclined surface. Together, the first separating element 26 and the second separating element 36 form a wedge gear.
- Such a wedge gear is shown in Fig. 5a and Fig. 5b, which shows a cross section of the lower part of a further embodiment of the deodorant dispenser according to the invention with a wedge gear, which has ten inclined surfaces, the rotating body 20 and the two couplings 21, 22 through a Plane containing the vertical container axis when the form fit of the two couplings 21 is released,
- 5a shows the deodorant dispenser with an existing form fit, in which the second latching element 35 is in engagement with the first latching element 25. As long as the second coupling 31 or the spindle 32 can rotate with the first coupling 21 and the rotating body 20, the form fit is maintained.
- Fig. 5b shows the deodorant dispenser with a released form fit.
- the wedge gear shown in Fig. 5a and Fig. 5b has symmetrical wedges (separating elements 26, 36), which is why, after the rotation blockage of the second coupling 31, a rotation of the rotating body 20 in the ascent direction as well as in the descent direction to release the form fit of the first latching element 25 with the second latching element 35 leads.
- FIG. 6a shows the first coupling 21 and a second coupling 31 aligned thereon before they enter into a form fit due to a rectilinear movement.
- the second latching element 35 engages when pushed together in a straight line in a first latching element 25, in which it is positively connected and non-rotatably connected with little rotational resistance, which is shown in FIG. 6b.
- connection of the first clutch 21 to the second clutch 31 can also be released in that part of the first clutch 21 and / or the second clutch 31 breaks, tears or is irreversibly separated in some other way when the torque exceeds a certain value (also not shown).
- FIG. 7a shows an oblique view of a deodorant dispenser with a refill pack with a refill elevator 40 that has partially emerged from the container 10 and rotated towards the container 10.
- FIG. 7b shows a cross section of the deodorant dispenser from FIG. 7a.
- a further rotation of the rotating body 20 therefore results in a rotation of the refill elevator 40 with respect to the container 10.
- a further rotation by a certain angle of rotation which is shown in FIG the inner wall of the refill container 10 ', which prevents further rotational movement of the refill elevator 40 with respect to the refill container 10' and the container 10.
- the refill elevator 40 can be more easily grasped by the user and removed together with the refill container 10 '.
- the elevator blocking area 44, 44 ' consists of a rib arranged on the lower edge of the refill elevator 40, the angular position of which is offset from the outer wall of the refill elevator 40 by the above-mentioned angle (here about 30 degrees).
- the elevator blocking area 44, 44 'can have individual sections arranged in the manner described, which sections can be connected and thereby stabilized by further sections.
- the elevator blocking area 44, 44 'can also have one or more wedge-shaped ribs which taper inwardly downwards (not shown).
- the mechanism for the refill elevator 40 shown in FIGS. 7a and 7b can also be transferred to the elevator 40 shown in FIGS. 1a and 1b, in which case only the elevator 40 together with the spindle 32 and the second coupling 31 are removed.
- the refill spindle 32 shown in FIG. 7b has, at its lower end, a spindle base 37 in the form of a flange-like widening, which has a recess (recognizable in cross section as a vertical surface) on its upper side.
- a corresponding projection is provided (not shown) which can snap into the recess when the refill elevator 40 is located at the lower end of the refill spindle 32.
- 8a shows an oblique view of a deodorant dispenser from above with an elevator 40 that has partially emerged from the container 10.
- the rotary body rotates again 20 to a rotation of the elevator 40.
- the elevator blocking area 44 strikes against the inner wall of the container, whereby a further rotation is blocked (FIG. 8b).
- a further rotation of the rotating body 20 in the ascent direction releases the connection between the first coupling 21 and the second coupling 31, since the elevator 40 and thus the spindle 32 can no longer rotate in this direction.
- 8c shows the spindle 32 and the elevator 40 in the container 10 after the connection between the first coupling 21 and the second coupling 31 has been released .
- the deodorant dispenser can then be refilled with a refill pack, for example.
