Abstract: An extraction capsule which contains a substance for preparing a liquid food, includes an extraction-side base with an outlet opening and a lateral wall which adjoins the base and has a terminal flange that is aligned radially outwards, and an injection-side filling opening which is closed by a sealing film. The extraction-side base has a peripheral edge region and a circumferential joint point which adjoins a base that lies in a first position on a plane prior to being used. The base can be brought from the first position into a second position which lies closer to the film sealing the filling opening. The extraction capsule has a console which is molded on the lateral wall and directly and/or indirectly on which an extraction-side sealing film to be perforated lies, with a perforator passing through the sealing film in the second position.

Abstract: A plastics-material capsule casing which, by virtue of its shaping, undergoes hardly any deformation during the extraction operation and provides for improved penetration of the injection needles of the extraction machine. The capsule casing has a corresponding conical lateral-surface wall which, at the upper periphery, has an outwardly projecting flange and, at the opposite end, is fully closed by a casing floor. The casing floor has a peripheral annular wall which merges from the conical lateral-surface wall via two opposing curvatures in an annular wall. The lower periphery of the annular wall merges into a panel via a thinned region which runs in an inclined manner in relation to the interior. The central panel has a wall thickness corresponding to the wall thickness of the lateral-surface wall. The thinned annular surface here forms an injection membrane.

Abstract: A simple, cost-effective dispensing device is proposed which can be independent of a container. The dispensing device has a peripheral outer wall which defines a dispensing space. The dispensing space is closed by a tear-resistant film on the push-open side, whereas the cover side is closed by a cover plate which can be formed in one part with the peripheral outer wall. The dispensing space can be subdivided into chambers by connecting walls. The plunger can be used to successively push open the tear-resistant film and the active ingredients in the chambers are thus dispensed.

Abstract: In order to prevent or minimize littering, the invention proposes a plastic closure (1) having a tamper-proof element. The plastic closure has a tamper-proof element that is as small as possible, and the plastic closure is largely secured against loss. The tamper-proof element consists of a plate (50), which is formed as part of the jacket wall (30) of the cover (3) by means of designed breaking point bridges (51, 52) and lies behind a first apron (25) in the closed state before the first opening and engages in a window (26) of the first apron by means of a locking hook. After the first opening, the plate (50) is separated from the cover and is held captive between the first apron (25) and a second, inner apron (27).
