Abstract
Abstract A stopper made of molded synthetic material comprises a domeshaped head and a hollow cylindrical body depending therefrom, the said body being closed at its lower end. The periphery of the body is provided with annular protruding ribs which coact with the inside of the bottle neck to insure fluid-tightness and these ribs are of substantially sinusoidal shape, each comprising an even number of undulations or wave lengths. With such an arrangement, if the neck has a zone of somewhat restricted diameter and/or of somewhat non-circular cross-section, as such is often the case with bottles for sparkling beverages, the stopper may nevertheless be easily extracted from the bottle by rotating it within the neck while it is submitted to a pulling force.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
77 words
A stopper of molded synthetic material, more particularly for bottles of sparkling beverages, comprising a head and a substantially cylindrical body depending therefrom, said body having a periphery formed with at least one undulated annular peripheral sealing bead of substantially sinusoidal shape, said sinusoidally shaped bead extending entirely around said periphery and having a wave length, said periphery of said body having a peripheral length and said wave length being an even sub-multiple of said peripheral length.
Claim 2
Dependent Claim
77 words
A stopper of molded synthetic material, more particularly for bottles of sparkling beverages, comprising a head and a substantially cylindrical body depending therefrom, said body having a periphery formed with at least one undulated annular peripheral sealing bead of substantially sinusoidal shape, said sinusoidally shaped bead extending entirely around said periphery and having a wave length, said periphery of said body having a peripheral length and said wave length being an even sub-multiple of said peripheral length.
Claim 3
Dependent Claim
77 words
A stopper of molded synthetic material, more particularly for bottles of sparkling beverages, comprising a head and a substantially cylindrical body depending therefrom, said body having a periphery formed with at least one undulated annular peripheral sealing bead of substantially sinusoidal shape, said sinusoidally shaped bead extending entirely around said periphery and having a wave length, said periphery of said body having a peripheral length and said wave length being an even sub-multiple of said peripheral length.
Claim 4
Dependent Claim
77 words
A stopper of molded synthetic material, more particularly for bottles of sparkling beverages, comprising a head and a substantially cylindrical body depending therefrom, said body having a periphery formed with at least one undulated annular peripheral sealing bead of substantially sinusoidal shape, said sinusoidally shaped bead extending entirely around said periphery and having a wave length, said periphery of said body having a peripheral length and said wave length being an even sub-multiple of said peripheral length.
Claim 5
Dependent Claim
18 words
In a stopper as claimed in claim 1, said wave length being equal to half said peripheral length.
Claim 6
Dependent Claim
32 words
In a stopper as claimed in claim 1, said body having more than one annular peripheral sealing bead and said beads being parallel to each other around the periphery of said body.
Claim 7
Dependent Claim
15 words
In a stopper as claimed in claim 3, said beads being equidistant from each other.
