STOPPER DEVICE COMPRISING A SUPPORTING CAP, AND CONTAINER PROVIDED WITH SUCH A DEVICE
First Claim
1. A stopper device for stopping a container having a neck of axis Δ
- , said device comprising;
an elastomer stopper;
a cover made of a plastics material that is suitable for covering both the neck and the stopper in place in the neck, and that is provided with locking means for locking it to the neck; and
a cap that fits over the top of the cover by means of a central stud and that is provided with a peripheral press rim connected to the central stud via at least one connecting web, wherein firstly the connecting web is elastically deformable in a manner such that, under the effect of an axial force, it enables the press rim to be moved axially from a raised position towards a lowered position via an intermediate position, and secondly, over a first deformation range, corresponding to the press rim being moved from the raised position to the intermediate position, said connecting web has a stiffness K1 greater than the stiffness K2 of the web over a second deformation range corresponding to the press rim being moved from the intermediate position to the lowered position.

Abstract
The invention relates to a stopper device for a container having a neck with a Δ axis. Said device comprises an elastomer stopper, a plastic cover that can cover both the neck and the stopper in place in the neck and comprises means for locking on the neck, and a cap adapted to the top of the cover by means of a central segment and provided with a peripheral supporting edge connected to the central segment by at least one connecting runout. According to the invention, the connecting runout is elastically deformable such that, under the effect of an axial effort, it enables an axial movement of the supporting edge from a raised position (R) to a lowered position, via an intermediate position (I), and, in a first deformation range corresponding to a movement of the supporting edge between the raised position (R) and the intermediate position, has a rigidity K1 which is higher than the rigidity K2 of the runout in a second deformation range corresponding to a displacement of the supporting edge between the intermediate position and the lowered position.
