DEVICE FOR APPLYING A MASS

Description

field of technology

[0001] The invention relates to a device for dispensing a mass according to the features of the preamble of claim 1. State of the art

[0002] Devices of the type in question are known, for example, from the cosmetics sector. For example, such a device can be designed in the manner of a deodorant stick, with a preferably solid mass which, supported on the device carrier in the device housing, can be moved via the spindle formation using the rotary handle into a protruding position relative to an opening in the device housing. Use of the device is preferably possible, particularly in this protruding position. Following a spindle retraction, the mass can be moved into a non-use position retracted into the device housing in the direction of the carrier's lower starting position.

[0003] Regarding the prior art, reference is made in this context to, for example, US 7 270 495 B1 or EP 2 052 640 B1. US 8,961,053 B1 discloses a device for dispensing a mass in which the spindle nut extends only upwards from the support. FR 968384 A discloses a device for dispensing a mass in which the support is cylindrical, with a cylindrical wall extending downwards from its edge region, which has an internal thread and interacts with the spindle. The central region is dedicated solely to the mass.

[0004] Document FR3025408A1 discloses the subject matter of the preamble of claim 1. Summary of the invention

[0005] Based on the prior art according to US 8,961,053 B1, the object of the invention is to provide a device for dispensing a mass, in which in particular an advantageous design of the spindle nut is provided.

[0006] This object is achieved in the subject matter of claim 1, wherein the spindle nut is closed at the front and projects upwards beyond the central region of the carrier in the direction of travel of the carrier.

[0007] Accordingly, such an end section of the spindle nut, which may extend beyond the surface of the support supporting the mass, can be encompassed or covered by the mass on its circumference, preferably also in a cap-like manner. The mass, for example, the mass in the form of a refill pack, can have a preferably central recess facing the mass support surface for receiving this end of the spindle nut.

[0008] This also creates the possibility of designing and arranging the spindle and spindle nut substantially in an area beneath the support (relative to a normal storage position of the device on a flat surface, in which the opening in the device housing points upwards to expose the mass). The spindle and spindle nut act telescopically as the support is displaced along the longitudinal axis, with maximum overlap of spindle and spindle nut in the direction of the longitudinal axis preferably being achieved in the lower starting position of the support, which is preferably limited by a stop. This ensures that the mass resting on the support has no direct contact with the spindle rotating about the longitudinal axis as the rotating handle is actuated.

[0009] The length of the spindle nut preferably refers only to a section of the spindle nut that, in the lower starting position, is in threaded engagement with the spindle or at least encompasses the threaded portions of the spindle. In the lower starting position, the spindle can extend up to the support or, if necessary, even beyond it by a comparatively smaller portion of its length.

[0010] The spindle nut is formed as an elongated sleeve which projects downwards beyond the support by a length corresponding to a multiple of the spindle's outer diameter, counter to the direction of travel. The sleeve can be provided with an internal thread over its entire length, which interacts with the external thread of the spindle. In the lower starting position of the support, the sleeve can, as is preferred, encompass the spindle over its entire length viewed in the direction of the longitudinal axis. The relevant length of the sleeve, by which the sleeve projects beyond the support in a direction averse to the mass carried by the support, can correspond, for example, to 5 to 20 times or more, furthermore, for example, to approximately 10 times the spindle's outer diameter.This characterization is also important as an alternative to the characterization that the spindle nut has a length in the direction of the longitudinal axis that is equal to or greater than the distance in the direction of travel of the carrier between the lower starting position and the maximum upper extended position.

[0011] In a further embodiment, the lower starting position of the carrier can be predetermined by a stop of an upper end of the spindle nut on the spindle. In this case, the upper end of the sleeve-like spindle nut can, for example, cover the spindle in a cap-like manner. Accordingly, the spindle nut is closed at the end. This end-side cap section of the spindle nut can, in the lower starting position of the carrier, engage the facing spindle end in a stop-limited manner. In this regard, a radially inwardly projecting section, for example in the form of a projection, can also be provided at the end of the spindle nut for stop-limiting interaction with the spindle end.

[0012] The lower starting position can also be defined by a stop of the lower end of the spindle nut on the spindle, possibly on a spindle base. This can be, in particular, the lower sleeve-like end of the spindle nut, which presses against the spindle base to limit the stop. Adjacent to the resulting stop area, the spindle can be rooted in the spindle base or extend out of the spindle base, for example, as is also preferred, in one piece with the spindle base.

[0013] The spindle base is preferably larger in diameter than the spindle having the external thread, for example by 2 to 10 times, further for example by about 5 times.

[0014] The piston-like, displaceable support can have a central region associated with the spindle nut and / or the spindle. In a further embodiment not according to the invention, this central region of the support can optionally be completely or partially penetrated by an upper end portion of the spindle.

[0015] This central region of the support is designed to be closed, so that, particularly in this region, a preferably completely closed surface can be created both in the direction toward the mass and in the opposite direction. This central region of the support can also be designed to be partially closed, for example by arranging webs or the like that may extend radially or concentrically with respect to the longitudinal axis.

[0016] According to a further preferred embodiment, the support can be designed to be completely closed in its area associated with the mass. Accordingly, according to this design, the mass carried by the support is preferably supported over its entire surface.

[0017] With respect to the direction of travel of the carrier or the orientation of the longitudinal axis, the spindle nut projects upward beyond the central region of the carrier in the direction of the mass. Accordingly, such an end section of the spindle nut, possibly extending beyond the surface of the carrier supporting the mass, can be encompassed or covered by the mass on its circumference, preferably also in a cap-like manner. The mass, for example the mass in the form of a refill pack, can have a preferably central recess facing the mass-supporting surface for receiving this end of the spindle nut.

[0018] In a preferred embodiment, the end section of the spindle nut may extend beyond the mass-supporting surface of the carrier by a dimension, viewed in the direction of the longitudinal axis, which may correspond to approximately 0.1 to 2 times, furthermore approximately 0.8 to 1.5 times, the spindle outer diameter.

Description of the embodiments

[0020] Shown and described is, firstly, with reference to the Figures 1 to 3, a device 1 according to the invention for dispensing a mass 2, for example in the form of a deodorant stick.

[0021] The device 1 is further designed for re-equipment with mass 2. This results in a refill device in which in particular a device housing 3, a rotary handle 4 and more preferably a cover cap 5 are reusable.

[0022] The overall preferably solid and stable mass 3 sits in the device housing 3, directly or indirectly surrounded by the wall 6 of the device housing 3, on a movable carrier 7. This carrier 7 is movable via a displacement arrangement 8 along a longitudinal axis x, which preferably also forms a central longitudinal body axis of the device 1, between a lowest starting position, as shown for example in Figure 3 , but also further, for example, in the Figures 4 and 5shown, and a maximum uppermost extended position. The uppermost extended position is shown in the illustration according to Figure 3 (first embodiment of the device 1) is indicated in dash-dotted lines. In addition, the illustration in Figure 7 using a fourth embodiment, this extended position.

[0023] The device housing 3 is, as a whole, essentially the shape-determining element for the device 1, wherein, with reference to a plan view in which the longitudinal axis x is represented as a point, the device 1 and in particular the device housing 3 are designed according to the Figures 1 to 11 and 16 to 26 may have an oval outer contour, with a longitudinal extension direction and a narrow extension direction viewed transversely thereto. Alternatively, according to the embodiment in the Figures 12 to 15 a circular floor plan shape considered in relation to the longitudinal axis x should be chosen.

[0024] The cover cap 5 in the covering position overlaps a housing opening 9 through which the longitudinal axis x passes centrally, through which the mass 2 can be moved into a usable protruding position via the displacement arrangement 8 after removal of the cover cap 5.

[0025] The carrier 7 is preferably circumferentially contoured to the inside of the directly facing and circumferential wall. The carrier 7, which can be moved like a piston in a direction r along the longitudinal axis x, can in particular have a closed central region 10. Furthermore, the surface 11 facing the mass 2, on which the mass 2 is supported in the device 1, can be completely closed.

[0026] In an alternative embodiment, an at least partially open support 7 may also be provided, possibly with the exception of the central region 10, through which, for example, an initial filling of the device 1 with mass 2 can be carried out. Such an initial filling can, for example, take place in an overhead position of the device 1 provided with a cover cap 5.

[0027] The displacement arrangement 8 comprises, in particular, a spindle 12 with a spindle axis that coincides with the longitudinal axis x in the use position of the device 1. The spindle 12 is rotationally fixedly connected to the rotary handle 4 in the use position of the device 1.

[0028] The rotary handle 4 can be adjusted according to the Figures 1 to 5and 22 to 26, with a preferred oval layout of the device 1, have a circular layout, with a diameter d that is selected to be larger, for example by 1.1 to 1.3 times, than the extension dimension e of the device housing 3 in the narrow extension direction, so that the rotary handle 4 protrudes in the shape of a segment of a circle on both sides in the region of the longitudinal edge sides of the device housing 3. For this purpose, the device housing 3 has opposing recesses 52 through which the rotary handle 4 partially protrudes. Furthermore, the diameter d of the rotary handle 4 can correspond approximately to 0.5 to 0.75 times the extension dimension f of the device housing 3 or of the device 1 as a whole in the longitudinal extension direction.

[0029] The rotary handle 4, preferably dimensioned as described above, can furthermore preferably be accommodated concentrically to the longitudinal axis x in an approximately pot-shaped receptacle 13 of the device housing 3, which receptacle 13 is provided facing away from the housing opening 9 in the region of a housing base 14 (compare, for example, illustrations in the Figures 3 to 5 and 25 and 26).

[0030] According to the Figures 1 to 5In the embodiments 1 to 3 shown, the rotary handle 4 can centrally form a thickened portion pointing into the housing interior and penetrating the receptacle 13 in the region of a central opening 15 to form a spindle base 16. This spindle base 16 can, as is also preferred in the aforementioned embodiments, be formed integrally and from the same material as the rotary handle 4, and moreover, it can also be formed integrally and from the same material, in particular with the spindle 12 formed directly on the spindle base 16. Furthermore, the spindle base 16 can have a diameter that can correspond to approximately 3 to 6 times, furthermore, for example, 5 times a spindle diameter g and / or approximately 0.5 to 0.9 times, furthermore, for example, approximately 0.7 times the rotary handle diameter d.

[0031] Furthermore, in addition to the spindle 12, the travel arrangement 8 includes a spindle nut 17 which interacts with the external thread of the spindle 12 via an internal thread.

[0032] The spindle nut 17 is connected to the carrier 7 in a rotationally fixed manner, more preferably formed integrally therewith and made of the same material.

[0033] The rotary movement of the spindle 12 via the externally graspable rotary handle 4, in cooperation with the spindle nut 17 and a rotation restriction of the carrier 7 in the directly associated housing acting in the circumferential direction with respect to the longitudinal axis x, causes the carrier 7 with the mass 2 to be displaced in the direction of travel r. The rotation restriction can be achieved simply by a non-circular, for example oval, layout of the housing and carrier 7. With a circular layout of the device 1 and thus preferably also of the carrier 7 and the housing wall immediately surrounding this carrier 7, the rotation restriction can be achieved, for example, by the interaction of a web oriented on the inside of the wall in the direction of travel r and a correspondingly positioned guide recess on the carrier 7, or vice versa.

[0034] The spindle nut 17 of the Figures 1 to 5illustrated embodiments is formed in the manner of a sleeve 18 which is elongated when viewed in the axial direction, with a length b viewed in the direction of the longitudinal axis x, which is preferably greater, more preferably approximately by a factor of 1.1 to 1.3 greater, than the distance a of the carrier 7 resulting in the direction of travel r between its initial position, as shown in the Figures 3 to 5 is shown and which is in Figure 3in dash-dotted line style, the maximum upper extension position. Due to this preferred length ratio, a spindle engagement in the spindle nut 17 can be ensured even in the maximum upper extension position of the carrier 7. Furthermore, as is also preferred, the spindle 12 can extend solely below the carrier 7, in particular below the surface 11 carrying the mass 2, as can the section of the spindle nut 17 or the sleeve 18 that is effective with the spindle 12. Accordingly, the spindle 12 advantageously does not penetrate into the area of the mass 2. The length b can also be selected (only) such that it only encompasses a length section of the spindle that is provided with a thread. In the illustrated embodiment, the length b' ends approximately where (above) the length c ends.

[0035] The position, for example, according to Figure 3is preferably limited by a stop. For this purpose, for example, a lower end 19 of the spindle nut 17 or the sleeve 18 can strike the spindle 12 or the spindle base 16 in this lower starting position. Alternatively, this stop limitation can also be provided by striking an upper end 20 of the spindle nut 17 or sleeve 18 against the facing spindle end 21 of the spindle 12 (cf. Figure 4 ). For this purpose, the spindle nut 17 or sleeve 18 can be designed, for example, to be cap-like and closed in the region of the upper end 20. A cap-like, closed design of the sleeve 18 can, however, also be important independently of a stop function, for example, with regard to ensuring the most compact possible design of the carrier 7.

[0036] In a further embodiment, the sleeve 18 can project downwards beyond the carrier 7 in the direction of the housing base 14 by a length c, counter to the direction of travel r, which length c can correspond to approximately one fifth to one tenth, furthermore approximately one eighth of the spindle outer diameter g. The length c is hereby removed continuously from a lower edge of the carrier 7 which is continuous in the cross-section, optionally, as in the exemplary embodiment, with the exception of an inner recess in the area of the spindle nut 17, of the carrier 7, in any case independently of a lip 63 of the carrier which projects further downwards on the edge and which may optionally be formed circumferentially, which is preferably provided additionally.

[0037] The spindle nut 17 or sleeve 18 is preferably connected to the carrier 7 in the central region 10, wherein according to one possible embodiment, the spindle nut 17 or sleeve 18 can protrude with its upper end 20 in the direction of travel r of the carrier 7 upwards beyond the central region 10 and beyond the surface 11. This can result in a height h of the spindle nut 17 above the carrier 7, measured over the surface 11 in the direction of the longitudinal axis x, which can correspond to approximately 0.8 to 2 times, furthermore approximately 1 to 1.2 times the spindle outer diameter g.

[0038] After the mass 2 has been used up, any remaining piece of the mass 2 can be easily removed via the housing opening 9 and replaced from above through the housing opening 9.

[0039] The procedure can be as follows: after the first mass, if any, has been used up, with the carrier preferably in its maximum extended position, the carrier is first lowered, and then only the mass is inserted from above. This can have a removable covering, for example made of paper, through which it can then be pressed down by hand. The mass can be pressed down until the carrier prevents further movement. The covering can then be removed.

[0040] The representations in the Figures 6 to 26show various further embodiments not according to the invention, in which a combination K is provided for exchanging a used mass 2, which combination K initially and essentially consists of the carrier 7 and the mass 2 arranged thereon, as well as the spindle 12. The combination K can also be referred to as a replacement or filling cartridge. Here, too, the spindle nut 17 is preferably formed directly and rotationally fixedly on the carrier 7, wherein the spindle 12 passes through the carrier 7 and its surface 11 in its longitudinal direction and dips into the area of the mass 2. This results in a lower starting position of the carrier 7, for example according to the illustrations in the Figures 8 , 12 , 19 and 22, in which starting position the carrier 7 is arranged at a slight distance in the axial direction from the spindle base 16. Here, too, a stop-limited lower starting position can result, for example, by the lower end 19 of the spindle nut 17 striking the spindle base 16.

[0041] A combination K consisting solely of spindle 12, carrier 7 and mass 2 is shown in the embodiments in the Figures 16 to 26 . In the use position, both the support 7 and the mass 2 supported by this support 7 are directly surrounded by the wall 6 of the device housing 3.

[0042] An alternative combination K is shown in the embodiments in the Figures 6 to 15, in which an inner housing 22 is additionally a component of the combination K. The wall 23 of the inner housing 22 directly surrounds the carrier 7 with the mass 2 supported thereon, wherein the inner housing 22 is furthermore preferably contour-adapted to the inner contour of the wall 6 of the device housing 3 with regard to the wall 23. In addition, as is also preferred, the inner housing 22 can be provided with an inner housing base 24 which is in particular and substantially penetrated by the spindle base 16.

[0043] The combination K inserted from above into the device housing 3 can, in particular in a configuration of the combination K with an inner housing 22, experience a stop limitation in the inserted position. Thus, the inner housing 22 can come into contact with a section of the housing base 14 of the device housing 3 or against a stop step 25 formed in the base area of the device housing 3 (see in particular Figure 11 and 15 ).

[0044] In the in the Figures 6 to 15In the embodiments shown with a combination K having an inner housing 22, in the inserted position the spindle 12 is guided via its spindle base 16 in the region of a central opening 26 in the inner housing base 24, optionally as also preferably, to rotate about the longitudinal axis x, forming a locking device in the direction of the longitudinal axis x. As also shown, the spindle base 16 can extend in the direction of extension of the longitudinal axis x, starting from the opening 26, both upwards in the direction of the carrier 7 and downwards beyond the inner housing base 24, wherein the spindle base 16 can furthermore have a downward-facing circular pot shape, in particular below the inner housing base 24.

[0045] The opening 26 can furthermore be formed in the region of a collar 28 which is conically circumferential with respect to the longitudinal axis x and is directed essentially in the direction of the carrier 7 and which can optionally act in a sealing manner against the circumferential wall of the spindle base 16.

[0046] In a preferred embodiment, the wall 23 of the inner housing 22 extends downwards beyond the inner housing base 24, so that the above-described cup-shaped section of the spindle base 16 is preferably accommodated within the space 29 enclosed by the wall 23 below the inner housing base 24. The downwardly facing circumferential end edge of the inner housing wall 23 can define a storage plane oriented transversely to the longitudinal axis x for storing the combination K on a preferably flat surface.

[0047] The downwardly cup-shaped design of the spindle base 16 can be achieved by a plug 27 that can be locked to the spindle base 16 or by a snap-on cap 60 (compare for example Figures 3 and 4 ) be covered.

[0048] In the above-described space 29 beneath the inner housing base 24, a holding base 30 can also be arranged, as is also preferred, which extends at least partially in the circumferential direction with respect to the longitudinal axis x. This holding base is preferably connected to the device housing 3, more preferably permanently connected, for example due to a one-piece design. For this purpose, the holding base 30 can be fastened in the circumferential direction, for example in sections, to the inside of the wall 6 of the device housing 3. In the sections of the holding base 30 resulting in the circumferential direction between the fastening areas, this holding base, in particular a locking web 31 running approximately in the direction of the longitudinal axis x, extends at a radial distance from the wall 6 of the device housing 3, for the passage of the foot section of the inner housing wall 23, which extends further below the inner housing base 24, in the inserted position of the combination K.

[0049] The locking web 31 of the device-side holding base 30 preferably has an outwardly directed locking lug 32 for locking cooperation with a counter-lock 33 directed inwardly on the inner housing wall 23 in the stop-limited insertion position of the combination K in the device housing 3. The combination K is thus locked in the device housing 3 via the inner housing 22.

[0050] The holding base 30 is further preferably provided centrally with an opening 34, which is preferably formed concentrically to the longitudinal axis x. This is further preferably penetrated from below in the direction of the receiving space for receiving the combination K by a holding wall 35, which preferably runs concentrically to the longitudinal axis x, of the rotary handle 4 arranged below the housing base 14. A radially outwardly projecting locking projection 36 engages behind the circumferential edge of the opening 34 to lock the rotary handle 4 to the device housing 3, allowing relative rotation of the rotary handle 4 with respect to the device housing 3 about the longitudinal axis x. According to one possible embodiment, the rotary handle 4 can thus be held captively on the device housing 3 even during an exchange of the combination K.

[0051] In a further embodiment, the spindle base 16 can be supported on an upwardly facing edge surface of the support wall 35 via a radially directed shoulder 37 when the combination K is inserted.

[0052] In the correctly inserted position of the combination K in the device housing 3, a coupling is created between the spindle 12 or its spindle base 16 and the rotary handle 4, for the rotationally fixed connection of the spindle 12 and the rotary handle 4 in the circumferential direction.

[0053] For this purpose, the rotary handle 4 can form a radially inwardly directed outer coupling part 38, particularly in the region of its support wall 35, which cooperates with an inner coupling part 39 of the spindle 12. The inner coupling part 39 is preferably formed on the outer wall side, correspondingly directed radially outward, of the circumferential, pot-shaped wall of the spindle base 16 extending below the inner housing base 24.

[0054] As can be seen particularly from the enlarged illustrations in the Figures 20 and 25 or 26, according to the further embodiments shown there, the coupling inner part 39 can alternatively be formed on the rotary handle 4 and the coupling outer part 38 on the spindle 12 or the spindle base 16.

[0055] The outer coupling part 38 and the inner coupling part 39 preferably cooperate in a form-fitting manner exclusively in the circumferential direction. For this purpose, one of the two coupling parts can, for example, have ribs 40 evenly distributed over the circumference, oriented substantially in the direction of the longitudinal axis x and projecting in the radial direction, which can engage in a form-fitting manner in correspondingly positioned slot-shaped receptacles 41 of the other coupling part.

[0056] A rotation of the rotary handle 4 about the longitudinal axis x is thus positively transmitted to the spindle 12. This in turn leads to a linear displacement of the carrier 7 with the mass 2 in the travel direction r.

[0057] As further shown in the representations according to the Figures 6 to 15 As can be seen, according to the embodiments shown there, the rotary handle 4 can have a plan contour that essentially corresponds to the device housing 3. In the embodiment according to the Figures 6 to 11 a substantially oval outline contour of the rotary handle 4, while in the embodiment according to the Figures 12 to 15 For example, a circular rotary handle 4 is provided.

[0058] In the case of a non-circular floor plan of the device 1 and a correspondingly non-circular floor plan of the rotary handle 4, basic rotary positions of the rotary handle 4 may be preferred in which the rotary handle 4 lies essentially in overlap with the associated device housing 3 in the direction of the longitudinal axis x. Thus, in the case of an oval floor plan design, as also shown, two basic rotary positions of the rotary handle 4 can result. These can, as is further preferred, be defined by an overridable detent. For this purpose, a lower surface 43 of the holding base 30, which essentially forms the housing base 14 and faces a cover 42 of the rotary handle 4, can in sections have a detent formation 44 in the form of a cup-like depression, into which a preferably shaped counter-detent formation 45 in the form of a raised area in the region of the rotary handle cover 42 falls.

[0059] In the illustrated embodiment, both radially inside and radially outside of the locking formations 44 or the counter-locking formations 45 with respect to the longitudinal axis x, there are circular ring-shaped regions 63 and 64, in which regions 63 and / or 64 the housing base 14 or the lower surface 43 of the holding base 30 can bear directly against the rotary handle 4 or its cover 42 in a supporting manner.

[0060] As can be seen particularly from the sectional view in Figure 9 As can be seen, two such depressions 44 and elevations 45 can be provided essentially diametrically opposite each other.

[0061] The stop resulting from the engagement of the elevation 45 in the recess 44 can be easily overridden by intentionally rotating the rotary handle 4.

[0062] To remove a combination K, possibly emptied of mass 2, from the device housing 3, only a pressure application to the spindle 12 along the longitudinal axis x in the travel direction r is necessary, made possible by the open-bottom design of the rotary handle 4, in order to overcome, in particular, the locking between the inner housing 22 and the device housing 3 and to convey the combination K along the longitudinal axis x out of the device housing 3. At the same time, the coupling between the outer coupling part 38 and the inner coupling part 39 is released.

[0063] By arranging an inner housing 22, the combination K can be designed to be substantially closed all around, particularly in the form of an unused replacement part. Thus, in particular in the unused state and in the area of the housing opening 9 created by the inner housing 22, a foil-like seal 46 of the mass 2, for example in the form of a dome, can span (compare, for example, Figures 8 and 12 ). Such a seal 46 can serve as an authenticity seal, but also, during the manufacture of the combination K, as a base for filling the inner housing 22 with mass 2 in an overhead position.

[0064] In the Figures 16 to 20 In the sixth embodiment of the device 1 shown, the rotary handle 4 also takes up the oval outline contour of the device housing 3.

[0065] The housing base 14 forms a downwardly facing, concentrically circumferential fastening wall 47 surrounding the central opening 15. When the combination K is inserted into the device housing 3, its downwardly facing peripheral edge surface is engaged by one or more locking lugs 48 arranged circumferentially distributed on the spindle base 16 and directed radially outward, for locking the combination K in the device housing 3 (see in particular Figure 20). In this locking position, the spindle base 16 is further preferably supported on the top side of the housing base 14 by a radial collar 49.

[0066] The cup-shaped section of the spindle base 16 carrying the radially outward-pointing locking lug 48 forms the coupling outer part 38 on the inside of the wall, facing radially inward.

[0067] After inserting the combination K into the device housing 3 and locking it as described above, the rotary handle 4 is attached from the underside. A centrally circumferential wall 50 of the rotary handle 4 forms, directed radially outward, the inner coupling part 39 for the rotationally fixed coupling with the spindle 12.

[0068] Concentric to the aforementioned wall 50, offset radially outwards, the rotary handle 4 can have a sealing wall 51 directed axially in the same direction as the wall 50, which in the arrangement position of the rotary handle 4 on the device housing 3 or on the spindle 12 can act from the radial outside in a sealing manner against the fastening wall 47 of the device housing 3 (compare Figure 20 ). This creates a seal between the device housing 3 and the rotary handle 4.

[0069] In the Figures 21 to 26In the seventh embodiment of the device 1 shown, as shown, a substantially oval outline contour of the device 1 as a whole can be given, with a rotary handle 4 which is preferably substantially circular in outline, the peripheral surface of which according to the first embodiments ( Figures 1 to 5 ) is partially exposed in the area of the long side of the device housing 3 in the area of window-like recesses 52 provided on the bottom for rotary operation.

[0070] The locking fixing of the combination K in the device housing 3, which allows the rotation of the spindle 12, is preferably achieved in this embodiment by locking engagement of the edge surrounding the opening 15 in the housing base 14 in a groove 53 formed concentrically to the longitudinal axis x on the spindle base 16 and open radially outwards.

[0071] The opening 15 is formed in a section of the housing base 14 that is preferably inwardly recessed relative to the device housing 3. The recessed section can be formed in a pot-like or dome-like manner, with a pot-like configuration having part of the pot base removed to form the opening 15. On the other hand, the opening 15 is preferably formed as a central opening in the dome-like configuration, relative to a dome-like opening.

[0072] Below the groove 53, the base 16 is pot-shaped, as is generally preferred, with a circumferential retaining wall 54 that extends into the central, downwardly open space created by the pot-shaped recessed design of the housing base 14. This retaining wall 54 forms a radially inward-facing locking recess 55 for engaging behind a locking lug 56 of the rotary handle 4.

[0073] In the inserted position of the combination K, a plug-in wall 57 of the device housing 3 runs at a radial distance from the holding wall 54 on the underside of the pot-shaped recessed section of the housing base 14, said plug-in wall 57 running concentrically to the longitudinal axis x.

[0074] Furthermore, the support wall 54 of the spindle base 16 forms the radially inwardly directed coupling outer part 58 according to the previously described embodiments.

[0075] The overall pot-shaped rotary handle 4 can have a handle base 58 which, in the assigned position, extends essentially in the installation plane of the device 1 defined by the housing base 14. Starting from this handle base 58, a radially inner handle wall 59 can extend in a preferably concentric arrangement, and a sealing wall 51 can extend outwardly from this handle wall at a radial distance therefrom.

[0076] In the arrangement position of the rotary handle 4 on the spindle 12, the sealing wall 51 can come into sealing contact with the plug-in wall 57 of the device housing 3, whereby a radially inner seal between the rotary handle 4 and the device housing 3 is achieved (compare Figures 25 and 26 ).

[0077] The radially inner handle wall 59 can carry one or more locking lugs 56 at the end, which can enter into a locking interaction with the locking rear grip 55 of the spindle 12 or spindle base 16.

[0078] In addition, the handle wall 59 can form the coupling inner part 39 pointing radially outwards for the rotationally fixed coupling of the rotary handle 4 and spindle 12.
