Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 205 words
A stopper for closing the neck of a receptacle containing a beverage and for seating against its rim, comprising: a hollow plastic stopper body comprising a head including an annular transverse base having a lower face shaped to overlie said rim and having an annular wall extending upwardly from an upper face of said base, and the body having at least one tubular skirt extending below the base and closed by a bottom wall at its free end, thE diameter of the said skirt being smaller than that of said head and sized to enter the neck of the receptacle; a liner of gas-impervious material comprising a transverse head of diameter larger than said skirt and snugly fitting within said annular wall above said base, and the liner having a tubular sleeve extending downwardly within and lining said skirt nearly to its bottom wall, and the skirt being displaced inwardly against the sleeve when the skirt is in the receptacle neck; a cap engaging said annular wall and closing the head of said body; and resilient packing surrounding the skirt at said lower face of the body for compression between the annular base and the rim of the receptacle when the stopper is closing it.
Claim 2
Dependent Claim 205 words
A stopper for closing the neck of a receptacle containing a beverage and for seating against its rim, comprising: a hollow plastic stopper body comprising a head including an annular transverse base having a lower face shaped to overlie said rim and having an annular wall extending upwardly from an upper face of said base, and the body having at least one tubular skirt extending below the base and closed by a bottom wall at its free end, thE diameter of the said skirt being smaller than that of said head and sized to enter the neck of the receptacle; a liner of gas-impervious material comprising a transverse head of diameter larger than said skirt and snugly fitting within said annular wall above said base, and the liner having a tubular sleeve extending downwardly within and lining said skirt nearly to its bottom wall, and the skirt being displaced inwardly against the sleeve when the skirt is in the receptacle neck; a cap engaging said annular wall and closing the head of said body; and resilient packing surrounding the skirt at said lower face of the body for compression between the annular base and the rim of the receptacle when the stopper is closing it.
Claim 3
Dependent Claim 38 words

The stopper of claim 3, the cap being provided with a central shank in contact with the base of the cup in the liner.
Claim 6
Dependent Claim 37 words
The stopper as in claim 4, the thickness of the bottom of the body below said junction being at least equal to the sum of the thicknesses of the two skirts of the body above said junction.
Claim 7
Dependent Claim 48 words
The stopper as in claim 5, the outer wall of the first skirt being provided with at least one sinusoidal rib, and with a bead located at the level of the lower face of the base of the head of the body and extending outwardly of the skirt.
Claim 8
Dependent Claim 23 words
The stopper as in claim 6, the outer diameter of the first skirt being reduced below the junction thereof with the second skirt.
Claim 9
Dependent Claim 39 words
The stopper as in claim 7, the upper face of the base of the head of the body being provided with a circular rib and the transverse head of the liner having a groove therein mating with said rib.

Claim 11
Dependent Claim 40 words
The stopper as in claim 9, in which the face of the base of the liner cup oriented opposite the sleeve comprises a central extension provided with an axial recess on whose bottom the end of the cap shank rests.
Claim 12
Dependent Claim 26 words
The stopper as in claim 10, in which the cap comprises an outer peripheral wall interlocking elastically with the interior of the head of the body.
Claim 13
Dependent Claim 37 words
