Description

Technical Field

[0001] The invention relates to a dispenser for powdered substances contained in individual packages, in particular a dispenser for substances contained in transparent plastic packages, wherein the package has a container part with a pull-out container cover device, wherein, further, after the container cover device is removed from the container part, the inhaled air flow is mostly sucked into the container part in such a way that two air flows flowing in through the gap of a cover part pivotable about a pivot axis empty the container part from its two ends and, after converging, arrive in a vortex chamber upstream of the suction nozzle, wherein, in addition, an external air inlet for a third air flow is constructed in the housing part covered by the cover in a radial extension relative to the pivot axis. Background Art

[0002] A dispenser of said type is known, for example, from WO 2009 / 138344 Al.

[0003] In addition, reference is made to DE 10 2008 023376 A1 for the prior art.

[0004] In the dispenser known from the last-mentioned document, the external air inlet opening is interrupted by rib-like webs in the cover itself. The user can grip it during use. The cover is designed to be almost identical in contour to the housing located below. Summary of the invention

[0005] Starting from this prior art, the object of the present invention is to improve a dispenser of the type in question in an advantageous manner with regard to operating technology.

[0006] This technical problem is solved in the subject matter of claim 1, based on the fact that the cover is designed with a radial extension relative to the pivot axis over a width corresponding to half the width of the cover or less in a partial area provided with an external air inlet for a third air flow, wherein the extension simultaneously forms a lower gripping projection for opening the cover and protrudes freely beyond the adjacent non-extended cover section, and the size of the extension relative to the non-extended cover section corresponds to one fifth of the width of the cover or more.

[0007] By means of this design, a dispenser of the type in question is further improved in a manner that is advantageous in terms of use. The provided, exposed extension of the cover provides a convenient grip for operating the cover, in particular for pivoting the cover about its pivot axis. Manual operation of the dispenser, in particular opening of the cover, is intuitive due to the exposed design of the extension.

[0008] Furthermore, the cover-side extension covers the external air inlet for the third air flow arranged in the housing part in a canopy-like manner from above in the closed position of the cover. Seen from the side view, the extension projects beyond the cover section facing the entire width from the root region of the extension relative to the distributor, in which the geometric pivot axis is represented as a point, in which root region the extension enters the cover section extending over the entire width.

[0009] The dimension of the extension here corresponds, for example, starting from the aforementioned root area and therefore relative to the adjacent non-extended area, to the cover width, in particular to a quarter or more of the maximum width of the cover preferably measured in an orientation parallel to the pivot axis, further preferably to one fifth to, for example, three quarters of the maximum cover width.

[0010] It is also preferred that the maximum width of the extension, for example formed in the root area of ​​the extension according to a possible embodiment, as viewed in an orientation parallel to the pivot axis, can further correspond to approximately half or less, for example up to one quarter, of the width of the cover, and in particular to approximately half or less, for example up to one quarter, of the maximum width of the cover as viewed in an orientation parallel to the pivot axis.

[0011] The extension is preferably also designed integrally with the cover and / or of uniform material. Therefore, in a further preferred embodiment of the cover, the extension is formed as a plastic injection-molded part simultaneously in the injection molding process for producing the cover, optionally in a two-component injection molding process, in which process, in particular, a second plastic component is provided relative to the extension. The extension can be provided with the second plastic component completely or only partially, for example on the edge side or on the upper surface side or on the lower surface side, or formed by this second plastic component.

[0012] The above and following ranges or numerical ranges or multiple ranges also include all intermediate values ​​in terms of disclosure, especially in the step length of 1 / 10 of the corresponding size, that is, it is also possible to be dimensionless. For example, half (0.5 times) or less representation also includes 0.49 or less disclosure. A quarter (0.25) or more disclosure also includes 0.26 or more disclosure. On the one hand, the present disclosure can be used to define the range limits from above and / or below. However, as an alternative or supplement, it is used to disclose one or more single values ​​in the corresponding given range. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] First refer to Figure 1 and 2 A dispenser 1 in the form of an inhaler is shown and described, which is implemented as a pocket-sized device that is easy to carry. It can have a substantially elongated rectangular housing 2, which has an aspect ratio of about 2:1 to 2.5:1 and a height, viewed perpendicularly to the longitudinal extension, which corresponds to about one quarter of the longitudinal extension. The components of the dispenser 1 are preferably implemented as injection-molded components.

[0037] In the extension of the longitudinal extension L of the housing 2 , a suction nozzle 3 projects therefrom. In the case of an integral one-piece design, the transition from the housing 2 to the suction nozzle 3 can be narrowed in a waist-like manner relative to the width extension of the housing 2 .

[0038] The suction nozzle 3 is penetrated in the longitudinal extension L by a suction channel 4 which ends at a suction nozzle 5 on the outlet side.

[0039] When the dispenser 1 is not in use, according to Figure 1 and 2 The suction nozzle 3 shown in the figure can preferably be covered by a closure cover 6. It can be inserted and held in the region where the suction nozzle 3 transitions into the housing 2 in a waist-shaped manner in a manner that substantially accommodates the width of the housing 2.

[0040] The transition area of ​​the housing 2 to the suction nozzle 3 is provided in the housing 2 with a circular swirl chamber 7 having a swirl chamber axis y extending essentially perpendicularly to the suction channel 4 (see Figure 1 5). The vortex chamber 7 extends substantially over the entire height of the housing 2 on a two-layer structure, wherein the chamber top 8 and the chamber bottom 9 are formed by a disc-shaped cover plate, which is preferably inserted and fixed on the housing 2 (see Fig.12and 1 3). The chamber top 8 and the chamber bottom 9 can be designed to be transparent. An opaque design is also feasible.

[0041] Furthermore, according to a possible embodiment, the chamber top 8 and the chamber top 9, for example, are Figure 3 As can be seen, there is a slot-shaped, for example substantially concentrically extending recess 58 with the vortex chamber axis y. They can be designed to be axially open outwards. However, this recess 58 is closed in the direction of the covered vortex chamber 7.

[0042] The recess 58 can be used, for example, as an assembly aid. In addition, this design enables a relatively thin chamber wall in the vortex chamber 7 and thus reduces the risk of depressions.

[0043] The housing part 10 adjacent to the vortex chamber 7 facing away from the suction nozzle 3 can be designed in a stepped manner in height. The remaining surface plane of the housing part 10, which is vertically offset relative to the vortex chamber top 8, extends approximately in the center plane relative to the height extension of the housing 2 (see, for example, Fig.10 , 1 5 and 16). On the end side, i.e. facing the offset plane of the housing part 10, an air channel 12 oriented essentially in the longitudinal extension of the housing 2 opens into a step 11 adjacent to the vortex chamber 7 opposite the suction nozzle 3. It has a diameter corresponding to preferably about 0.7 to 0.8 times the free step height. At the other end, the air channel 12 opens into the vortex chamber 7, in particular the superstructure of the vortex chamber 7.

[0044] The stepped region of the housing part 10 is initially designed to be open upwards, facing away from the housing part bottom, and is essentially divided in the longitudinal extension by a vertical bar 47 arranged centrally with respect to the width viewed transversely to the longitudinal extension, thereby obtaining two regions of at least approximately equal size on both sides of the vertical bar 47. The two regions are covered by a central bottom plate 46, which in turn forms an offset surface plane of the housing part 10. The central bottom plate 46 is essentially closed around the edge with a step lower edge, further below the opening of the air channel 12 and with the edge delimitation of the stepped region of the housing part 10, and is further preferably locked to the housing part 10 in an undetachable manner during operation.

[0045] A receiving portion 13 open to the flat surface is formed in the middle bottom plate 46. It has a long hole-like contour and is formed in the axial extension of the air channel 12 at a distance from the air channel opening in the step 11. The contour and depth of the groove-like receiving portion 13 are adapted to the contour and height of the container part 14 to be received, and accordingly, the end sides are rounded in the longitudinal extension to receive the capsule-shaped container part.

[0046] As from especially Figures 14 to 21 As can be seen from the further representation of FIG, the container part 14 is designed in the manner of a transparent plastic package, wherein the container part 14 stores a powdery substance M. For this purpose, the container part 14 is made of a plastic material in a trough shape, wherein a planar support section 15 is further adjoined on the surrounding opening edge of the container part 14. Overall, the container part 14 is formed as a recess by the support section 15.

[0047] The substance M stored in the container part 14 is sealed in the non-use position by an aluminum foil covering the entire surface of the support section 15 and the container part 14, which is a container cover device 16. The container cover device 16 can be pulled out from the support section 15 to release the container part 14 or the substance M stored therein, for which the aluminum foil or the container cover device 16 extends freely in the opposite direction from the narrow area of ​​the support section 15 oriented transversely to the longitudinal extension of the container part 14 and covers the area of ​​the container cover device 16 that seals the container part 14 and the support section in a freely flat manner. The free end of the container cover device 16 freely protrudes from the end edge of the support section 15 facing away from the pivoting area of ​​the container cover device 16 to form a flag-shaped pull-out handle 17.

[0048] The receptacle 13 for the container part 14 formed in the middle bottom plate 46 is positioned in a region that is vertically offset lower relative to the middle bottom plate surface. The vertical offset corresponds essentially to the material thickness of the transparent plastic packaging 18 composed of the container part 14, the container cover device 16 and the support section 15 outside the container part 14. In addition, in particular, the length of the recess as viewed in the longitudinal extension of the housing 2 is adapted to the length of the support section 15 as viewed in the longitudinal extension of the container part 14. The recess surface surrounding the receptacle 13 serves as a support for the support section 15 when the transparent plastic packaging 18 is inserted.

[0049] The housing part 10 is provided with a cover 19. It is foldably articulated on the housing part 10 in the region of the step 11 about a pivot axis x directed transversely to the longitudinal extension of the housing 2. The cover 19 has a top 20. Side walls 21 extending on both sides in the longitudinal extension of the housing 2 are designed integrally with the cover top 20 and are located laterally of the relevant side surfaces of the fixed housing part 10 in the closed position of the cover.

[0050] For example, Figures 3 to 8 It can also be seen in the illustration of that the cover 19 is provided with an extension 60 oriented in the longitudinal extension L of the dispenser 1. It can be used primarily and essentially as a lower gripping projection U for pivoting the cover 19.

[0051] The extension portion 60 can refer to Figure 5The top view of the dispenser 1 extends beyond the edge surface 61 of the cover 19 facing away from the suction nozzle 3 on the side of the longitudinal center axis z of the dispenser 1. The extension 60 preferably does not exceed or significantly exceed the longitudinal center axis z in the width extension, that is, in a direction transverse to the longitudinal extension L, and contacts it if necessary.

[0052] exist Figure 5 , the width e of the cover 19 is plotted, which is measured at the widest part of the cover 19 transversely to the longitudinal extension L or parallel to the pivot axis x. This width e of the cover 19 can correspond approximately to the length q from the pivot axis x to the free front edge face 62 of the extension 60, which is measured in the longitudinal extension L, and further corresponds approximately to 1.1 to 2 times this length q.

[0053] According to the reference Figure 5 An auxiliary line k extending through the extension 60 transversely to the longitudinal extension L in the top view obtains a width f of the extension 60 which is preferably less than half the cover width e and therefore corresponds to approximately 0.35 to 0.4 times the cover width e according to the illustrated embodiment.

[0054] The auxiliary line k here extends with an offset g relative to the outermost region of the front edge surface 62 when viewed in the longitudinal extension L, which corresponds to approximately 0.1 times the cover width e.

[0055] A second length d of the extension 60 observed in the longitudinal extension L is obtained relative to the rear wall 26 of the housing part 10, into which the external air inlet 57 opens, which, as described in more detail below, can correspond to approximately 0.25 to 0.4 times, further, for example, approximately one third, of the width e and / or the cover length q. The second length d is measured here along a further auxiliary line h, which in the longitudinal extension L is oriented centrally through the aforementioned auxiliary line k.

[0056] The cover section 63 with the edge surface 61 designed adjacent to the aforementioned extension 60 in a preferred embodiment protrudes beyond the rear wall 26 similarly to the extension 60, but only has a relatively small first length d', which can correspond, for example, to 0.25 to 0.5 times, or even about one third, of the second length d of the extension 60. The first length d' is hereby measured along a further auxiliary line j (see Figure 5 ) is drawn, which extends in the longitudinal extension L in the middle of the width extension of the cover section 63 starting from the longitudinal center axis z in the area of ​​the rear wall 26.

[0057] from Figure 5It can be further seen from the top view in that the inner edge surface 64 of the extension 60 extends substantially parallel to the longitudinal center axis z, wherein further preferably a radius can be formed in the transition to the edge surface 61 of the extension 60 and in the transition to the leading edge surface 62, respectively.

[0058] The outer edge surface 65 preferably extends without stepping into the facing outer wall surface of the cover 19, wherein the edge produced in a top view preferably extends along an arc of a circle with a radius m. The radius M can correspond to approximately 1.1 to 1.5 times the width e of the cover 19. This results in a tapering of the extension 60 towards its free end, as described in accordance with Figure 5 Top view of the .

[0059] Especially from Figure 6 and 7 In the sectional view in FIG. , the different free lengths d and d′ of the cover section 63 and the extension 60 can be seen. In particular, these sections (cover section 63 and extension 60) preferably extend along a circumference with a radius n in the sectional view, wherein the radius n can preferably correspond to a multiple of the cover width e, for example 4 to 6 times, more preferably about 5 times. The respective free ends of the extension 60 and the cover section 63 tend to point in the direction of the bottom plane of the dispenser 1 or the housing 2 in a beak-like manner.

[0060] The cover section 63 and the extension 60 preferably extend in a common plane without stepping, in particular on the surface side, into the remaining cover surface.

[0061] In addition, especially with reference to Figure 5 In the top view in FIG. 1 , the extension 60 protrudes freely beyond the adjacent non-extended cover section 63 by a dimension p. The dimension p is obtained by a difference, which is measured in the longitudinal extension L between the intersection 66 between the auxiliary line j extending in the middle of the cover section 63 and the edge surface 61 and the intersection 67 between the auxiliary line h of the extension 60 and its front edge surface 62. The dimension p can correspond to one fifth or more of the width e of the cover 1 9, further, for example, about 0.25 to 0.3 times the width e.

[0062] The extension 60 of the cover 19 designed as described above provides the user with an easy-to-operate, tab-shaped lower gripping projection U, which allows the cover 19 to be easily opened and closed.

[0063] The gripping area for opening the cover 19 which is further preferably provided thereby is also sufficiently spaced apart from the external air inlet opening 57 in the rear wall 26 .

[0064] The cover 19 is locked and retained in the cover closed position, for which a locking projection 23 is provided on the side wall 21 of the cover 19, which is inserted into a locking recess 22 on the housing part side. The locking retention formed in this way can be easily eliminated by the user to open the cover 19.

[0065] In order to facilitate the handling of the dispenser 1, in particular during the operation of the cover, a rib-like protrusion 59 can be provided on the wall outer side of the side wall on the housing part side, on which the above-mentioned locking recess 22 can also be constructed, which allows easy and safe gripping.

[0066] In the closed position of the lid, the top lower side 24 is supported by the vertical strips 49 formed on the top lower side on the upper side of the facing middle bottom 46, and thus preferably on the flat surface of the recess surrounding the receiving receptacle 13. When the transparent plastic packaging 18 is inserted into the receptacle 13 on the middle bottom side and thus compensates for the vertical offset in the middle bottom 46, the top lower side 24 or the vertical strips 49 arranged on the top lower side preferably support the transparent plastic packaging 18, in particular the container lid device 16 forming the pull-out handle 17 in the free end region. Accordingly, the inserted transparent plastic packaging 18 in the closed position of the lid is fixed on the one hand by the almost form-fitting insertion of the container part 14 into the receptacle 13, and on the other hand by the relevant surfaces of the lid top 20 and the recess on the middle bottom side, wherein further, the lateral support of the transparent plastic packaging 18 by the support section 15 is provided on the one hand by the step 11 and on the other hand by the boundary of the recess.

[0067] In addition, the cover 19 is also supported with a vertical strip 49 arranged on the underside of the cover on a flat surface of the adjacent, intermediate base plate 46 which is raised relative to the recess for accommodating the transparent plastic packaging 18, wherein, further, the vertical strip 49 of the cover 19 at least partially restricts the flow path at the same time.

[0068] In the longitudinal extension of the recess for accommodating the transparent plastic packaging 18 in the middle bottom plate 46, locking lugs 50 are formed on both sides of the edge of the recess, which overlap the support section 15 in the container part-attachment position and also overlap the container cover device 16 in the non-use position, so that the inserted transparent plastic packaging 18 is fixed in the attachment position due to the overlap of the locking lugs 50 when the cover 19 is opened. The locking lugs 50 are overcome during the insertion and removal of the transparent plastic packaging 18 by the thin-walled and optionally elastic design of the support section 15 on the transparent plastic part side.

[0069] In addition, a marking 43 is applied to the surface side of the recess on the middle bottom side on the pull-out side of the receiving portion 13, which is in particular a marking in the form of a color marking. In the attached position of the transparent plastic packaging 18, the marking 43 vertically overlaps with the window-like cutout 51 in the supporting section 15, which is exposed during the pulling-out process of the container cover device 16 to prepare for inhalation.

[0070] The transparent plastic packaging 18 is inserted into the dispenser 1 in such a way that the folded edge of the container cover device 16 faces the air duct 12 when oriented parallel to the pivot axis x and further the cantilevered pull-out handle 17 protrudes from the housing 2 in the opposite direction beyond the edge of the recess, which is achieved by a slit-like pull-out opening 25 that passes through the correspondingly remaining intermediate bottom plate 46 and the cover 19 that is pivoted into the closed position. The latter is adapted to the width of the container cover device 16 in its width as viewed transversely to the longitudinal extension of the housing 2. The vertical height of the pull-out opening 25 corresponds essentially to the material thickness of the container cover device 16.

[0071] The correct orientation of the transparent plastic package 18 to be inserted in the dispenser 1 is ensured by the eccentric arrangement of the receiving portion 13 arranged in the middle bottom plate 46 in the longitudinal extension of the dispenser 1 or the recess. The transparent plastic package 18 has a different side length of the supporting section 15 in the longitudinal extension that is adapted to the eccentric arrangement of the receiving portion 13, so that the insertion of the transparent plastic package 18 can only be realized in a predetermined orientation.

[0072] The vertical strip 49 protruding from the underside of the cover forms, in the closed position of the cover, together with the facing surface of the intermediate base 46, an air flow channel 27 which is guided in an arc-shaped path with reference to the vertical projection onto the intermediate base 46. The air flow channel 27 is first guided as a container channel section 30 to the end of the intermediate base-side receptacle 13 or the container part 14 accommodated in the receptacle 13 which is further away from the housing-side air channel 12. Starting from this end, the air flow channel 27 extends, forming a 180° bend region 52, to a channel section which runs at least approximately parallel to the longitudinal orientation of the receptacle 13 and which further transitions into a direct channel section 31, surrounding the receptacle 13 on one side.

[0073] At the other end of the receptacle 13, an air flow channel 27 is further formed in a substantially axial extension of the housing-side air channel 12, so that in the closed position of the cover, the air flow is directly connected to the housing-side air channel 12. The direct channel section 31 and the section of the air flow channel 27 corresponding to the air channel 12 jointly open into a collection section 32, which is formed in the region of the opening of the housing-side air channel 12 facing the air flow channel 27 in the illustrated embodiment.

[0074] In particular, the arcuate path channel 53 formed by the container channel section 30 and the direct channel section 31 tapers in its free flow cross section relative to the average cross section of the air flow channel 27 in the direction of the collecting section 32, and preferably tapers at about 40% of the average cross section. This tapering nozzle-like end section of the direct channel section 31 is provided with the reference numeral 54.

[0075] Ribs 55 are further formed on the underside of the cover, overlapping the receptacle 13 or the container part 14 inserted in the receptacle 13. They extend transversely between two vertical bars 49 that delimit the section of the air flow channel 27 that overlaps the receptacle 13 and have a height, as viewed in the closed position of the cover, that is selected so that in the inhalation ready position the downwardly projecting free front edges of the ribs 55 extend into the gap above the open container part 14 that is exposed after the container cover device 16 has been pulled out.

[0076] The ribs 55 deflect the air flow channel 27 in the direction of the container part 13 or in the direction of the container part 14 located in the container part 13 and outward from the container part 14. For at least low-loss deflection, the ribs 55 are preferably provided according to Fig.11 The vertical cross section of the rib 55 is provided with concavely curved side surfaces 56 on both sides. The side surfaces are provided with a radius preferably adapted to the cross-sectional radius of the air flow channel 27, wherein, further, the rib 55 has a width observed in the flow direction in its free end region pointing downward in the direction of the receptacle 13, which corresponds to approximately 0.1 to 0.3 times, preferably approximately 0.2 times, the length of the receptacle 13 observed in the same direction.

[0077] Furthermore, the rib 55 is arranged centrally with respect to the longitudinal extension of the receptacle 13 or of the container part 14 and is oriented transversely to the longitudinal extension.

[0078] The air flow channel 27 is accordingly arranged in accordance with Fig.14 After the container lid device 16 has been pulled out, it is essentially guided in a double S-shape due to the above-described arrangement and design of the ribs 55 , which takes place while penetrating the container part 14 .

[0079] Furthermore, air inlet slits 29 are provided in the lid top 20, overlapping the arc-shaped path channel 53 and more particularly overlapping the curved region 52, which preferably open upwards in the closed position of the lid and more preferably also open laterally through the associated side wall 21. In this way, a grid-like covering of the inlet, in particular the curved region 52, is achieved.

[0080] The housing-side air duct 12 which is open toward the housing part 10 opens at the other end into the deflection section 28 of the swirl chamber 7 and further into the superstructure 33 of the swirl chamber 7 which extends substantially above the partition plane between the intermediate base 46 and the cover 19 .

[0081] The superstructure 33 of the vortex chamber 7 is basically designed in an annular shape, for which an annular wall 34 extending over the entire height of the superstructure 33 is provided in the center. Starting from the air channel inlet, the annular channel 35 of the superstructure 33 extends at an angle of about 270° (refer to Figure 4 ), the annular space 35 then transitions into an annular channel 39 also formed in the layer structure 38 arranged below, by means of a perforation 37 that penetrates the open layer structure bottom 36. It is also bounded radially inwardly by an annular wall 34 that passes through substantially the entire vertical height of the vortex chamber 7.

[0082] Immediately downstream of the bottom-side perforations 37 in the direction of flow, a partition wall 40 is drawn in the region of the superstructure 33 , which closes off the inlet annular space in the direction of the peripheral flow to the air channel 12 and extends radially from the associated annular wall section.

[0083] The annular channel 39 of the substructure 38 extends from the 90° bend region of the upper annular channel 35 over approximately 270° to the connection with the suction channel 4 of the suction nozzle 3 .

[0084] The perforations 37 of the connecting layer structure or annular channels 35 and 39 extend over an angular range of approximately 180°, which, viewed in the flow direction, covers an angular range of 90° to 270° for the upper annular channel 35 and an angular range of 270° to 90° for the lower annular channel 39. Accordingly, there is a transition between the two annular channels over a range of approximately 180°.

[0085] There is therefore a substantially spiral air guidance in the swirl chamber 7 , which takes place by causing the air sucked in through the swirl chamber to rotate through a total of 360°, which in turn takes place through two planes lying one above the other.

[0086] The external air opening 41 opens into the annular space 39 of the lower structure 38 of the vortex chamber 7 in a vertically overlapping manner with the opening of the air channel 12 into the upper structure 33, and the external air channel 42 of the external air opening 41 passes through the housing 2 in such a way that the external air opening 41 opens tangentially to the annular space 39. On the other hand, the external air channel 42 opens into the gap 44 remaining between the intermediate bottom plate 46 and the housing bottom at the lower side of the opening on the step side of the air channel 12 when it extends in the longitudinal extension direction of the housing 2. The latter forms an auxiliary air channel 45, which is configured alternately with the vertical strips 47 on the intermediate bottom plate side. The area of ​​the gap 44 formed below the receiving portion 13 is closed to the rear of the housing by the vertically extending rear wall 26 of the intermediate bottom plate 46. In the end section assigned to the rear wall 26, the height of the vertical strip 47 which essentially divides the gap 44 in the longitudinal extension is reduced in order to fluidically connect the intermediate floor areas configured side by side, wherein an external air inlet 57 is provided in the rear wall 26 in association with the gap area formed on the lower side of the arc-shaped path channel 53. Accordingly, the external air inlet 57 is adjacent to the container cover device 16 protruding from the rear wall side of the housing 2 in the suction operating position.

[0087] In order to inhale the substance M, the cover 19 has been pivoted open to the position according to Fig. 9 After the transparent plastic packaging 18 is brought into the open position, the container part 14 is first inserted in such a way that the container part 14 is accommodated in the receiving part 13, which is achieved by supporting the supporting section 15 on the transparent plastic side on the corresponding concave surface of the middle bottom plate 46. The additionally provided locking lugs 50 here catch the supporting section 15 and the container cover device 16, which is preferably located in the closed position, and the container cover device 16 is further double-layered by the guidance of the folded sides in the end area of ​​the transparent plastic packaging 18, especially in the area of ​​the locking lugs 50. The freely protruding pull-out handle 17 freely protrudes beyond the housing end for operation.

[0088] After closing the cover 19, the transparent plastic packaging 18 is fixed in the housing 2. In this case, the transparent plastic packaging 18, in particular the pull-out handle 17, extends laterally on the extension 60 and is therefore in particular associated with the non-extended cover section 63. The extension 60 and the pull-out handle 17 extend accordingly in a side-by-side arrangement. The pull-out handle 17 is freely located in the free area of ​​the cover 19 on the side of the extension 60 for operation (see Figure 1 7).

[0089] Then, the container part 14 is opened by rolling and pulling out the container cover device 16, for which the pull-out handle 17 protruding through the pull-out opening 25 is pulled in the pull-out direction r. Due to the transparent design of the cover 19, especially the transparent design of the section of the cover 19 covering the displacement area of ​​the container cover device 16, the pull-out process is visible. The marking 43 arranged on the surface of the middle bottom plate 46 helps the user to determine the position to which the container cover device 16 must be pulled to ensure that the substance M stored in the container part 14 is fully exposed. The window-like cutout 51 of the support section 15, which was initially covered by the container cover device 60, is exposed during the rolling and pulling out process of the container cover device 16, and the marking 43 can then be seen through the cutout 51. The user is accordingly guided on how to correctly use the dispenser 1.

[0090] After the container cover device is pulled out of the container part 14, the substance M is exposed in the flow path. Due to the lack of the cover device, the container part 14 is now part of the flow path and is connected to the section of the air flow channel 27 leading to the collection section 32 and further to the air channel 12 at one end and to the arc-shaped path channel-like section of the air flow channel 27 at the other end, which in turn opens into the collection section 32 at the end side.

[0091] The dispenser 1 is preferably held between the thumb and the index finger like a flute for inhalation. By suctioning through the suction nozzle 3, air enters the arcuate path channel 53 of the air flow channel 27 through the air inlet slit 29, after which the air entering is divided so as to pass through the direct channel section 31 which leads directly to the collection section 32 and through the container channel section 30 which leads directly to the container part 14. The powdered substance M stored in the container part 14 is discharged through the container channel section 30, after which the air portion b of the doped substance is combined with the air portion a in the collection section 32 through the direct channel section 31. By the cross-sectional design of the direct channel section 31 which tapers toward the collection section 32, a suction effect is achieved on the section of the air flow channel 27 which also opens into the collection section 32, which suction effect helps to empty the container part 14 by the blowing air introduced through the container channel section 30. By passing through the spiral double-layer vortex chamber 7, a uniform distribution of the substance M in the air flow is achieved. Before leaving the vortex chamber 7 and entering the suction channel 4 of the suction nozzle 3, other external air c is added via the external air opening 41. The external air c sucked in like secondary air enters the vortex chamber 7 through the external air channel 42, wherein the external air opening 41 leading to the lower structure 38 points in the direction of the opening opposite to the suction channel 4. The external air flow c merges with the air flows a and b carrying the substance in the lower structure 33 of the vortex chamber 7 just before the transition to the suction channel 4.

[0092] Due to the roof-like extension of the cover 19 (see Figure 6), the external air inlet openings 57 for inhaling external air c are in a protected position so that they are not accidentally covered, for example by fingers, during normal inhalation.

[0093] During the inhalation process, the free container cover device-flag-like structure at least largely closes the pull-out opening 25, thereby preferably counteracting the inhalation of auxiliary air.

[0094] By the described design, the suction or air guidance inside the housing 2 is achieved by the bypass device of the container cover device 16 moved into the extended position for suction. The suction air flow that removes the substance M from the container part 14 is guided without interference. The air guidance of the air flow channel 27, especially the nozzle-shaped taper of the direct channel section 31 in the direction of the collection section 32, is optimized. The dispenser 1 is suitable for sucking in a variety of different substances M, especially substances that differ in particle size and / or mixture.
