One-way valve device
First Claim
1. A one-way device for discharging a flowable material from a container of a reducible volume comprising an outer cap which includes an exit opening for the material, said one-way device comprising:
- a valve seat arranged in a neck of the container and comprising a base body which extends transversely across the opening of the container neck and rests on the inner wall of the container neck and includes at least one passage opening, and a projection which extends in axial direction of the container neck towards the exit opening;
an elastic seal which comprises an annular section resting on the base body, and a sleeve-like section which surrounds the projection at a radial distance where in the closed state, the one-way valve device rests on the projection; and
an annular inner cap secured to the container neck and grips over said neck with an outer annular wall and an inner annular wall,the outer cap being arranged to be movable between a rearward closing position and an advanced opening position, and comprising an inner annular attachment which in the closing position presses the sleeve-like section of the seal into abutment with the projection.

Abstract
A one-way valve device comprises a valve seat arranged in the neck of a container that extends transversely across the interior of the neck and defines a plurality of passage openings. A pin-like projection is formed on the valve seat and extends axially to the exit opening. An elastic seal is held on the valve seat and comprises a sleeve-like section which surrounds the projection of the valve seat with the exception of its end section which rests on the end section of the projection. Applying pressure to the contents of the container axially displaces the sleeve-like part of the seal relative to the pin-like projection, so that the contents of the container can exit. In the closed position, an annular projection of an outer cap firmly presses the sleeve-like section of the seal against the projection of the valve seat, so that no container contents can exit.
