DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0052] FIG. 1 and FIG. 2 show a sectional representation of an apparatus 1 for output of an output medium 4 or fluid or spray medium, with a first embodiment of a capsule holder 9 according to the invention. The apparatus 1 comprises a container 2, which forms an interior 3 for holding the output medium 4, a head 5 for closing the container 2, the capsule holder 9 for holding a gas capsule 10, an operating element 6, which is preferably configured in the form of a lever or of a pushbutton, as well as an output nozzle 7.

[0053] Furthermore, such apparatuses comprise or the apparatus 1 comprises a piercing unit 29 for the gas capsule 10 for proper functioning, so as to pierce a membrane of the gas capsule 10 open when the gas capsule 10 is arranged in the capsule holder 9 and the capsule holder 9 is screwed into the head 5, more precisely into a gas capsule connector 8 arranged on the head 5, so as to produce and guarantee a fluidic connection between the gas capsule 10 and the apparatus 1. Furthermore, such apparatuses comprise or the apparatus 1 comprises a removal system (removal valve 30) for proper functioning, for controlled output.

[0054] In this regard, the capsule holder 9 has a threaded ring 12 with which the capsule holder 9 can be screwed onto the gas capsule connector 8, wherein the threaded ring 12 has an inside thread 13 for this purpose, in the exemplary embodiment shown, the (clear) thread diameter 14 of which is greater than a gas capsule outside diameter 11, and thereby the gas capsule 10 can be inserted into the capsule holder 9 through the threaded ring 12. In detail, the gas capsule 10 can be inserted into a gas capsule holder element 15 of the capsule holder 9, wherein for easier and better handling, the gas capsule holder element 15 is surrounded by a cover 17, at least in part. In this regard, the gas capsule holder element 15 contacts an inner surface 18 of the cover 17.

[0055] FIG. 3A and FIG. 3B each show a detailed sectional representation of the first embodiment of the capsule holder 9 according to the invention, wherein the cover 17 surrounds the gas capsule holder element 15 and also the threaded ring 12 completely from the outside. In this regard, FIG. 3B does not show a cover 17, for a better understanding. In detail, the gas capsule holder element 15 is inserted into the cover 17 and has an opening 16 for holding or introducing the gas capsule 10. The threaded ring 12 is arranged in the region of the opening 16 of the gas capsule holder element 15, wherein the ring is firmly connected with the gas capsule holder element 15 in a connection region 20, by means of shape fit and/or material fit. For example, the connection can be implemented by means of gluing, welding or the like.

[0056] FIG. 4A and FIG. 4B (without cover 17) show a sectional representation of a second embodiment of the capsule holder 9 according to the invention, wherein the cover 17 surrounds the gas capsule holder element 15 completely and the threaded ring 12 only partially. In this regard, the cover 17 has a projection 19, which engages into a groove 23 of the threaded ring 12, wherein the groove 23 is arranged opposite the opening 16, on the side of the capsule holder end, so that at least a partial region of the threaded ring 12 is not enclosed by the cover 17.

[0057] FIG. 4C shows, in a side view, the gas capsule holder element 15, wherein an anti-rotation securing means 21 in the form of a knurling is provided on an outer surface of the gas capsule holder element 15. In this regard, the anti-rotation securing means 21 of the gas capsule holder element 15 can stand in engagement with the inner surface 18 of the cover 17, which is configured in the manner of a sleeve, in particular when using the capsule holder 9.

[0058] FIG. 5A and FIG. 5B (without cover 17) show a sectional representation of a third embodiment of the capsule holder 9 according to the invention, wherein the threaded ring 12 likewise has the groove 23, which, however, is arranged approximately in the center of the threaded ring 12, and into which groove 23 a projection 25 of the gas capsule holder element 15 that faces inward engages. In this regard, the projection 25 that faces inward is formed by a bead 22 of the gas capsule holder element 15 that lies on the outside. In this regard, it is additionally provided that the gas capsule holder element 15 is connected with the threaded ring 12 in the connection region 20, wherein the connection according to the above explanations can be implemented by means of gluing, welding or the like.

[0059] In addition, it is possible, according to FIG. 5A, that the threaded ring 12 comprises a formed edge 24 that is arranged in the region of a second end 28 of the threaded ring 12, wherein the threaded ring has a first end 27, viewed along a longitudinal axis 26 of the capsule holder, which end faces the gas capsule holder element 15, as well as the opposite second end 28. The cover 17 is in engagement with the formed edge 24 of the threaded ring 12 and encloses the formed edge 24 at least in certain sections.

[0060] FIG. 6A and FIG. 6B (without cover 17) show a sectional representation of a fourth embodiment of the capsule holder 9 according to the invention, wherein the inner surface 18 completely encloses the cover 17 of the gas capsule holder element 15 from the outside, and the gas capsule holder element 15 in turn completely encloses the threaded ring 12 from the outside.

[0061] Although only a few embodiments of the present invention have been shown and described, it is to be understood that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
