Abstract:
1. A stopper which engages with a ring-shaped neck in a press fit into a container, comprising a circular bottom section which seals the container opening, and a head section which rises above the container and encompasses a slide that extends through the center of the head section, the rim of the head section having a maximum diameter that does not exceed the external diameter of the container on the container opening, wherein the slide can be pushed against the force of a spring device in one direction over the rim of the container and, when released, returns to its retracted initial position as a result of the spring force, the spring device being formed by at least one elastically deformable web which is mounted or formed on the slide or on the stopper, wherein opposing sides of the slide each end in circumferential sections, a first one of said circumferential sections forming an outer surface for receiving a first applied force for advancing the slide and causing said second one of said circumferential sections to protrude from the stopper, said second one of said circumferential sections receiving a second different applied force to remove the stopper from the container, the slide comprising two laterally free-cut, freely ending spring tabs which when the slide is pushed forwards are bent inwards by obliquely inwardly directed wall sections of the side sections, wherein a restoring force directed towards the initial position is created, and wherein the spring tabs have curved outer contours tapering inwards towards the free end.
