A downward-facing resilient material that extends in a radial direction to surface 32 on the bowl-shaped extension 26 55 can be pressed together so that the snap bulge 58 comes to rest on the upper edge of the closure via the neck bead 56 on the housing 24, so that the cap and neck of the container can be pushed over at this point, the container itself is carried by the housing 24 to provide such radial compression will. to favor the neck of the container, so that the beads

In the present example, liquid from 60, 56 and 58 should be able to jump over one another, when it is placed on the container 10 by means of a closure known per se, one of the snap-action pumps, which bulges one, is conveyed out, in the example shown, the one with the Has pump cylinder 34, the preferably cap, a conical inclined surface 58 ", which below in one piece η ^; t the lid 18 of the container half of the apex 58 'is deformed downwards. The pump cylinder 34 is a conical surface that widens towards the top 65. If the cap is opened through the container lid and can be screwed onto the container neck, it presses a pump piston 36, the conical inclined surface 58 «the I incisbulst 56 radially speaking passage channels (not shown), which presses inward the present example

In order to establish an axial distance between the (icwindcgangcn, which prevents the cap from being unscrewed from the container again later), one of the beads, in the present example the snap bead 58 on the cap, has a conical slope surface 58 /), which , seen in the axial direction upwards, widens from the apex 58 'and on which the neck bead 56 slides after crossing the ridge 58' during the subsequent expansion, so that the cap is pulled further up on the container neck after the thread is already out Are hingrilf. Preferably, the inclination of this Bösehungsfläche 58 b is sufficiently steep, so that thereby the cap is held with sufficient security on your container.

It should also be mentioned that the inner diameter of the cap 2 "is somewhat above the snap bead 58 is kept smaller than the outer diameter of the neck bead 56, so that even after the superimposing the bulges 56 and 58 at the point of the neck bulge 56 there is a radial force. on this way it is achieved that the container neck slightly is stretched lengthways and thereby mim four l'nterscite presses sealingly against the lid of the cap, while at the same time through the vertical component of the Force on the Böschunusiläne the cap is pressed onto the neck of the container and a tight seal evokes.

On the underside of the cover, an annular, rigid stopper 66 projects therefrom, which closes fits into the container opening 14. Because the upper linden tree of the container neck is shaped as a truncated cone is. is due to an axial pressure force between Lid 18 and the upper F-nd of the container neck generates a radially inwardly acting force that the Tries to narrow container oil Tnung 14 so that it rests firmly against the plug radially. The stopper in turn presses against the radially inwardly curved container neck due to the reaction force and generates thus an axial force of the container neck against the lid 18. The stopper prevents that the flexible plastic neck deforms fluently due to the continuously acting force or with the Zeil the elastic resilience weakens.
