Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
158 words
In a stopper for closing the neck of a container, said stopper having a part adapted to be situated outside the container and provided with a prehensile device on which the user may pull to rupture an inviolability device associated with the stopper, said stopper further comprising a skirt which is connected near its lower edge to a peripheral frangible wall forming said inviolability device and by said frangible wall to a retaining sleeve adapted to be located inside the container, the improvement according to which said skirt is provided with a peripheral protective rib positioned adjacent the edge by which the retaining sleeve is connected to said skirt, so that during the insertion of the stopper into the neck of the container the protective rib bears on the retaining sleeve and in which peripheral protective rib is discontinuous and comprises a plurality of pins generally regularly positioned about the periphery of the skirt adjacent the retaining sleeve.
Claim 2
Dependent Claim
158 words
In a stopper for closing the neck of a container, said stopper having a part adapted to be situated outside the container and provided with a prehensile device on which the user may pull to rupture an inviolability device associated with the stopper, said stopper further comprising a skirt which is connected near its lower edge to a peripheral frangible wall forming said inviolability device and by said frangible wall to a retaining sleeve adapted to be located inside the container, the improvement according to which said skirt is provided with a peripheral protective rib positioned adjacent the edge by which the retaining sleeve is connected to said skirt, so that during the insertion of the stopper into the neck of the container the protective rib bears on the retaining sleeve and in which peripheral protective rib is discontinuous and comprises a plurality of pins generally regularly positioned about the periphery of the skirt adjacent the retaining sleeve.
Claim 3
Dependent Claim
157 words
In a stopper for closing the neck of a container, said stopper having a part adapted to be situated outside the container and provided with a prehensile device on which the user may pull to rupture an inviolability device associated with the stopper, said stopper further comprising a skirt which is connected near its lower edge to a peripheral frangible wall forming said inviolability device and by said frangible wall to a retaining sleeve adapted to be located inside the container, the improvement according to which said skirt is provided with a peripheral protective rib positioned adjacent the edge by which the retaining sleeve is connected to said skirt, said rib comprising means for directly transmitting to the sleeve, pressure exerted on said skirt during insertion of the stopper into the neck of the container, without subjecting the frangible wall to said pressure, so that damage to said frangible wall is avoided during insertion of the stopper.
Claim 4
Dependent Claim
157 words
In a stopper for closing the neck of a container, said stopper having a part adapted to be situated outside the container and provided with a prehensile device on which the user may pull to rupture an inviolability device associated with the stopper, said stopper further comprising a skirt which is connected near its lower edge to a peripheral frangible wall forming said inviolability device and by said frangible wall to a retaining sleeve adapted to be located inside the container, the improvement according to which said skirt is provided with a peripheral protective rib positioned adjacent the edge by which the retaining sleeve is connected to said skirt, said rib comprising means for directly transmitting to the sleeve, pressure exerted on said skirt during insertion of the stopper into the neck of the container, without subjecting the frangible wall to said pressure, so that damage to said frangible wall is avoided during insertion of the stopper.
Claim 5
Dependent Claim
43 words
Device as claimed in claim 2 in which the skirt is generally cylindrical in shape and has an axis which coincides with that of the retaining sleeve, the external diameter of said skirt being less than the internal diameter of the retaining sleeve.
