DESCRIPTION OF THE EMBODIMENTS

[0059] Shown and described is a device 1 for discharging a substance 2, for example as a kind of deodorant stick.

[0060] In particular, the device 1 further has a device housing 3 and a rotary handle 4.

[0061] The overall preferably solid and stable substance 2 rests on a movable support 7 in the device housing 3, directly surrounded by a housing wall 6 of the device housing 3. In the unused state, the substance 2 located on the support 7 can be covered by a cover cap 5.

[0062] The support 7 can be moved by way of a movement unit 8 along a longitudinal axis x, which preferably forms a central longitudinal body axis of the device 1 at the same time, between a lowermost starting position, for example as shown on FIGS. 2 and 3, but beyond that, for example, also on FIGS. 8 and 9 as well as 12 and 13, and an upper extended position. In the illustration according to FIG. 2 (first embodiment of device 1), this extended position is denoted by dot-dashed lines.

[0063] The upper extended position can involve a maximum upper extended position. The support 7 can here come to abut against a stop 55 preferably designed as a radially protruding circular disk, allocated to an upper end of the spindle 14.

[0064] As a whole, the device housing 3 essentially determines the shape of the device 1, wherein, with reference to a layout in which the longitudinal axis x appears as a point in said layout, the device 1 and in particular the device housing 3 can have an oval outer contour, with a longitudinal extension direction L and a narrow extension direction S viewed transversely thereto.

[0065] In the covering position (e.g., see FIG. 2), the cover cap 5 overlaps a housing opening 9 that is centrally passed through by the longitudinal axis x, and through which the substance 2 can be moved into a usable protruding position via the movement unit 8 after removing the cover cap 5.

[0066] The support 7 preferably has a contour that is peripherally adjusted to the progression of the interior side of the circumferential housing wall 6. The support 7 that can be moved like a piston in a traveling direction r along the longitudinal axis x can here in particular have a closed central area 10. In addition, the surface 11 that faces the substance 2 and against which the substance 2 is supported in the device 1 can be completely closed in design. A circumferential wall 12 of the support 7 can abut against the facing interior surface of the housing wall 6 as a kind of lip.

[0067] With the possible exception of the central area 10, an at least partially open support 7 can be provided in an alternative configuration, for example which can be used to fill the device 1 with substance 2. For example, this type of filling can take place in an overhead position of the device 1 provided with a cover cap 5.

[0068] In particular, the substance 2 can also be spanned in the form of a dome prior to an initial use, for example by a film-like seal 13 (e.g., see the embodiments according to FIGS. 2 and 12). Such a seal 13 can serve as tamper evidence, but beyond that also as a base for filling the device housing 3 with substance 2 in an overhead position while introducing substance 2 into the device housing 3. In addition, such a seal 13 provides an in particular gastight seal to the outside for the space surrounding the substance 2 prior to an initial use.

[0069] As an alternative to a seal 13, the cover cap 5 itself can be used for sealing purposes. The cover cap 5 here has a sealing lip 54 that interacts with the interior surface of the housing wall 6 in the area of the housing opening 9 (compare FIGS. 8 and 9).

[0070] In particular, the movement unit 8 has a spindle 14 with a spindle axis, which coincides with the longitudinal axis x in the use position of the device 1. The spindle 14 is connected in a rotationally fixed manner with the rotary handle 4 at least in the use position of the device 1, and together with the latter comprises a spindle part 15.

[0071] According to the depicted embodiments, the rotary handle 4 can have an adjusted oval layout given a preferably oval layout of the device 1, and is further preferably positioned on the lower face of a housing base 16 aligned transverse to the longitudinal axis x.

[0072] According to the embodiments 1 and 2 shown on FIGS. 1 to 11, the rotary handle 4 can form a sleeve 17 concentric to the longitudinal axis x, which passes through the housing base 16 in the area of a central base opening 18 in the direction toward the device interior.

[0073] As also preferred, the sleeve 17 can here be designed in an integral and materially uniform manner with a handle cover 19, which surrounds the sleeve 17 and extends radially outward from the latter, transitioning into a handle wall 20 that runs essentially parallel to the longitudinal axis x in a cross section according to FIG. 2 or 8. This correspondingly results in an overall pot-shaped configuration of the rotary handle 4 with a downwardly facing pot opening.

[0074] As evident in particular from the sectional views on FIGS. 2 and 3 (first embodiment of the device 1), the sleeve 17 can also extend downwardly beyond the handle cover 19 and into the space surrounded by the handle wall 20, for example over a length viewed in the direction of the longitudinal axis x that can correspond to about one fifth to one third of the height of the handle wall 20 viewed in the same direction.

[0075] The sleeve opening can have a design that is downwardly closed in the direction toward the space surrounded by the handle wall 20, for example directly by the handle cover 19, e.g., according to the embodiment on FIG. 10, or as the result of inserting a separate, for example snap-locked or friction-locked, insertion cap 21.

[0076] In the depicted first embodiment (FIGS. 1 to 7), the sleeve 17 transitions in preferably an integral or materially uniform manner into the spindle 14, spaced axially apart from the handle cover 19. The sleeve 17 here forms a spindle base 22 with in particular an enlarged diameter relative to the spindle 14, wherein the foot-side connection of the spindle 14 is further established in particular in the area of a sleeve cover 23 that partially covers the sleeve 17.

[0077] In the second embodiment shown on FIGS. 8 to 11, the spindle 14 and the rotary handle 4 have a two-part design. During the assembly of the device 1, these parts are connected with each other in a torsionally rigid manner, in particular by inserting the spindle 12 from above along the longitudinal axis x into a plug-in receptacle 24 of the rotary handle 4 formed concentrically to the longitudinal axis x. The plug-in receptacle 24 is here preferably surrounded at a distance by the sleeve 17.

[0078] The related end area 25 of the spindle 13 is preferably given an unround shape by flat sections in a cross section transverse to the longitudinal axis x (see also FIGS. 16 and 17), so that a torsionally rigid connection can be achieved between the spindle 14 and rotary handle 4 given a corresponding inner geometry of the plug-in receptacle 24.

[0079] Independently of the configuration of the spindle part described above, the male thread of the spindle 14 interacts with a female thread of a sleeve part 26. This sleeve part 26 is tightly bound to the support 7, preferably by being formed in an integral and materially uniform manner with the support 7. The spindle 14 and sleeve part 26 form the movement unit 8.

[0080] The sleeve part 26 here further preferably extends on the lower face of the surface 11, wherein an end 27 of the sleeve part 26 that faces downward in the use state can define a stop for the lower starting position.

[0081] Given a device 1 according to the first exemplary embodiment, this sleeve part end 27 interacts as a limiting stop with the sleeve cover 23 of the integrally designed spindle part 15 (see FIG. 2).

[0082] Due to the torsionally rigid guidance of the support 7 along the housing wall 6, rotating the rotary handle 4 around the longitudinal axis x thereby produces a linear movement of the support 7 in the movement direction r.

[0083] The spindle part 15 can here be rotationally guided on the device housing 3 by having a locking protrusion 28 formed in the area of the housing base 16 engage into a locking recess 29 of the spindle part 15 (see in particular magnified view on FIG. 5).

[0084] The locking protrusion 28 can here face radially inward and be formed essentially directly on the level of the housing base 16, possibly defining the base opening 18 at the same time. The radially inwardly directed closing surface 30 of the locking protrusion 28 can here form the opening edge, and possibly come to abut against a facing rear surface 31 of the locking recess 29, doing so on a radius a in relation to the longitudinal axis x.

[0085] The locking protrusion 28 can be overlapped in an axial direction by a counter-locking protrusion 32 that is circumferentially formed on the outside of the sleeve 17 of the spindle part 15, and conically expands from axially above to axially below, forming a control slant 33. The control slant 33 is used in particular for assembling the spindle part 15 acting together with a counter-control slant 34 on the lower face of the housing-side locking protrusion 28.

[0086] The radially outward facing front surface 35 of the counter-locking protrusion 32, e.g., that runs concentrically to the longitudinal axis x, is formed on a radius c, wherein the selected radius c is larger than the radius a of the closing surface 30, for example by the factor of 1.05 to 1.1.

[0087] The control slant 33 of the counter-locking protrusion 32 transitions axially upward into a circumferential surface of the spindle part 15 or the sleeve 17 that runs concentrically to the longitudinal axis x. A housing-side seal protrusion 37 abuts against this circumferential surface 36, and in the first exemplary embodiment shown can be designed like a lip in cross section.

[0088] The seal protrusion 37 is preferably shaped like a sleeve overall, with a tapering section 38 that results at least partially axially upward in cross section according to FIG. 5, and at least partially runs according to a cone.

[0089] As also preferred, the sleeve-shaped seal protrusion 37 can here be molded onto the upper face of the housing base 16, here surrounding the counter-locking protrusion 32 of the spindle part 15 at a distance with a foot section 39 that possibly runs concentrically to the longitudinal axis x. The tapering section 38 extends from this foot section axially upward and bent radially inward, wherein the front surface of the seal protrusion 37 comes to tightly abut with a radially inner seal surface 40 against the circumferential surface 36 of the spindle part 15.

[0090] The seal surface 40 is here arranged on a radius b selected to be smaller than the radius a of the closing surface 30 of the locking protrusion 28, and also selected to be smaller than the radius c of the front surface 35 of the counter-locking protrusion 32. For example, the radius b can correspond to about 0.8 to 0.98 times, further for example to about 0.85 to 0.95 times, the radius dimension a.

[0091] In addition, the sealing area between the seal protrusion 37 and the circumferential surface 36 of the spindle part 15—viewed from the rotary handle 4—is positioned axially above the lock between the locking protrusion 28 and the locking recess 29, while a possible counter-locking protrusion 32 of the spindle part 15 can be arranged between the seal area and the locking area described above.

[0092] In the embodiments on FIGS. 8 to 17, the device housing 3, in particular the device base 16, surrounding its base opening 18, forms a sleeve section 41 in the housing interior that is directed axially upward and concentrically to the longitudinal axis x, as viewed correspondingly from the rotary handle 4. As also preferred, the latter can be designed in an integral and materially uniform manner with the housing base 16, and beyond that with the housing wall 6.

[0093] In the second embodiment of the device 1 shown on FIGS. 8 to 11, this sleeve section 41 overlaps the housing base-side sleeve 17 in an axial direction, and forms a guide 42 for the spindle 14 designed concentric to the longitudinal axis x on the lower face spaced axially apart from the plug-in receptacle 24 for the end area 25 of the spindle 14. In the area of the downwardly facing end, the guide 42 engages with radially inwardly directed locking protrusions 43 into a circumferential groove of the spindle 14 forming a locking recess 44.

[0094] The lock and seal between the rotary handle 4 and the device housing 3, in particular the housing base 16, is achieved in this second embodiment in particular between the housing-side sleeve section 41 and the handle-side sleeve 17 (see in particular magnified view on FIG. 11).

[0095] As in the first exemplary embodiment described above, the housing base 16 here as well at the same time essentially forms the base opening 18 circumferentially bordering a locking protrusion 28, which enters into a locking recess 29 of the sleeve 17 allocated on the outside of the wall in an axial direction and in a locking manner.

[0096] Viewed from the rotary handle 4, a sealing arrangement is here as well provided axially above this lock, wherein a seal protrusion 37 formed on the wall interior of the sleeve section 41 comes into contact with the circumferential surface 36 with its seal surface 40 in the area of a facing, grooved, circumferential depression of the handle-side sleeve 17.

[0097] In this design, the radially inner seal surface 40 of the seal protrusion 37 and the radially inner closing surface 30 of the locking protrusion 28 can lie on a circular line that is concentrically circumferential to the longitudinal axis x and has about the same radius a or b (see FIG. 11).

[0098] In the third embodiment shown on FIGS. 12 to 17, the handle cover 19 is centrally lowered like a pot. This yields a circumferential, vertically downwardly directed pot wall 45, which passes over into a pot base 46 directed transverse to the longitudinal axis x. In this embodiment, the plug-in receptacle 24 is formed on the pot base 46 facing into the interior of the sleeve section 41.

[0099] The wall of the sleeve section 41 is here formed axially downward further beyond the housing base 16, and here extends inside of the pot-shaped formation of the handle cover 19, essentially radially inwardly flanking the pot wall 45.

[0100] The end of the sleeve section 41 that faces downward in the cross section according to the illustration on FIG. 15 forms the seal protrusion 37, wherein the downwardly free seal edge 47 of the seal protrusion 37 that here results is in this cross section preferably tightly surrounded by the spindle part 16 in a U-shaped manner, here in particular the pot-shaped configuration of the rotary handle 4.

[0101] As evident in particular from the magnified view on FIG. 15, the seal protrusion 37 is both radially inwardly and radially outwardly flanked by a respective U-leg 48, 49, as well as underpinned on the lower face by the pot base 46 that connects the U-legs in a web-like manner. The radially outer U-leg 49 is preferably formed by the pot wall 45. As with the pot wall 45, the radially inner U-leg 48 extends concentrically to the longitudinal axis x, but does so over a height viewed in the axial direction that can correspond to about 0.4 to 0.6 times the height of the pot wall 45. In particular this radially inner U-leg 48 interacts in a sealing manner with the sleeve section 41, in particular with the end-side seal protrusion 37 and the seal edge 47. Furthermore, there can additionally or even alternatively thereto be a seal between the seal edge 47 and the radially outer U-leg 49 and/or the U-web formed by the pot base 46.

[0102] The seal edge 47 that interacts in particular with the U-leg 48 here preferably runs on a radius d, which can correspond to about one eighth to one fifth of the largest inner diameter e of the device housing 3 in the longitudinal extension direction L.

[0103] The radially outer U-leg 49 or the pot wall 45 can here at the same time form an inwardly facing locking recess 29 for engaging a radial expansion of the seal protrusion 37. This radial expansion acts as a locking protrusion 28.

[0104] Viewed proceeding from the rotary handle 4, a radially inwardly protruding counter-locking protrusion 32 can be formed axially above the inner U-leg 48 on the spindle part 16, in particular on the pot wall 45 of the rotary handle 4, and engage into a corresponding counter-locking recess 50 of the sleeve section 41. Viewed in an axial direction, this counter-locking formation 50 is correspondingly positioned between the foot-side sealing zone of the sleeve section 41 and the lock preferably likewise provided in this area and the housing base 16 or the handle cover 19.

[0105] Given a preferably unround layout of the device 1 and corresponding unround layout of the rotary handle 4, rotational base positions of the rotary handle 4 can be preferred, in which the rotary handle 4 essentially overlaps the allocated device housing 3 in the direction of the longitudinal axis x. In the case of an oval layout configuration of the kind also shown, two rotational base positions of the rotary handle 4 can thus arise. As further preferred, the latter can be defined by an overrunable lock. For this purpose, sections of an undersurface 51 of the housing base 16 facing the handle cover 19 of the rotary handle 4 can have a locking formation 52 in the form of an elevation, which in one of the rotational base positions of the rotary handle 4 can fall into a preferably form-fitting counter-locking formation 53 in the form of a cup-shaped depression in the area of the handle cover 19.

[0106] In the exemplary embodiments shown, circularly circumferential areas relative to the longitudinal axis x preferably arise both radially inward and radially outward from the locking formations 52 or the counter-locking formations 53, wherein the housing base 16 or the undersurface 51 of the housing base 16 can supportively abut directly against the rotary handle 4 or its cover 19 in these areas.
