Embodiment Construction

[0023] The screw cap described below is characterized in that, when it is opened for the first time, it is removed from the mouth of the container, that is to say it performs a lateral movement in addition to a rotational movement. There is a hook device on the inner wall of the protective band, which works together with a step on the container when sealing. In this way, a force is exerted on the protective strip which, on the one hand, is directed parallel to the transverse movement and, on the other hand, causes a radial expansion of the protective strip.

[0024] In a first embodiment of this screw cap, the screw cap 1 has a top seat 3 which covers the mouth of the container and from which extends an outer cover 5 which surrounds the container, thus forming a joint also called A cup-shaped screw cap 1 for a sealing cap. As shown in the figure, there are several vertical ribs on the outer surface of the outer cover 5, that is, ribs parallel to the central axis or the rotati...

Abstract

The present invention relates to a screw cap for a container, in particular a bottle, having a top base from which an outer cover extends and surrounds the circumference, the screw cap has a The fixing mechanism for fixing the screw cap on the container, and a protective strip located on a bottom edge of the outer cover away from the top seat, the protective strip is connected with the screw cap through a stress breaking line, and there is at least one elongation on the protective strip. The zone of elongation makes the protective strip extensible in a direction perpendicular to its circumferential direction. The screw cap is characterized in that the protective strip possesses at least one elastic zone formed by the lower part of the protective strip (11) between the fixing piece and the elastic support strip.

Description

technical field [0001] The invention relates to a screw cap for a container, especially a screw cap for a bottle. Background technique [0002] Screw caps of the type described above are already known. It either has an internal thread that engages an external thread on the container, or it has a bayonet connection. Importantly, in both cases, when the screw cap is opened, it performs a rotational movement and, above all, it also performs an axial and transverse movement. With these two movements, the mouth of the screw cap container can be removed. Such screw caps are known to have a protective band known as a "seal". When the container is opened for the first time, that is to say, when the screw cap is removed from the container for the first time, this band is partially deformed or damaged, so that its shape changes. Consumers can tell from its altered appearance that the container is no longer original and may have been tampered with. A considerable opening force is ...
