Abstract
Abstract A liquid container, particularly containing carbonized drinks, comprising a conical thin-walled plastic container with a bottom formed substantially as part of a sphere having its central portion selectively deformable, and a plane metal sheet lid secured by a folded edge or seal to the edge of the container and provided with a tear-away tongue to provide a pouring opening when tearing off the tongue.

Claim 1
Independent Claim
259 words
A container assembly for carbonated beverages comprising: A thin walled plastic cup-like portion having a conically tapered side wall open at its upper wide end and integrally joined to a hemispherical shaped thin walled closure portion to define a convex outer surface at its bottom narrow end; the upper end of said side wall having a continuous edge extending outwardly and downwardly from the upper end thereof to form a sealing lip; a flat circular shaped metallic cover positioned upon said upper end and having its marginal portion folded over and around said sealing lip to provide an air-tightly sealed container assembly; said cover having a tear-away tongue portion for forming an outlet for the container assembly when the tongue is removed; a gripping ring secured to the tongue portion of said cover to facilitate removal of said tongue portion; said hemispherical closure portion having a circular shaped deformation surrounding a center portion of said closure portion; said center portion being collapsible either prior to closure of the container assembly or subsequent to the opening of said container assembly to form a concave outer surface enabling said circular shaped deformation to serve as a surface for supporting said container assembly; said center portion being further deformable upon closure of said container assembly to bulge outwardly and collectively define said convex outer surface with the remainder of the hemispherical closure portion surrounding said circular shaped deformation to provide increased volume for the carbonated contents when the container assembly is filled and sealed to reduce the gas pressure in said assembly.

Dependent Claim

A container assembly for carbonated beverages comprising: A thin walled plastic cup-like portion having a conically tapered side wall open at its upper wide end and integrally joined to a hemispherical shaped thin walled closure portion to define a convex outer surface at its bottom narrow end; the upper end of said side wall having a continuous edge extending outwardly and downwardly from the upper end thereof to form a sealing lip; a flat circular shaped metallic cover positioned upon said upper end and having its marginal portion folded over and around said sealing lip to provide an air-tightly sealed container assembly; said cover having a tear-away tongue portion for forming an outlet for the container assembly when the tongue is removed; a gripping ring secured to the tongue portion of said cover to facilitate removal of said tongue portion; said hemispherical closure portion having a circular shaped deformation surrounding a center portion of said closure portion; said center portion being collapsible either prior to closure of the container assembly or subsequent to the opening of said container assembly to form a concave outer surface enabling said circular shaped deformation to serve as a surface for supporting said container assembly; said center portion being further deformable upon closure of said container assembly to bulge outwardly and collectively define said convex outer surface with the remainder of the hemispherical closure portion surrounding said circular shaped deformation to provide increased volume for the carbonated contents when the container assembly is filled and sealed to reduce the gas pressure in said assembly.
