Abstract
Abstract A closure assembly for containers wherein a synthetic-resin plug-type cap has a disk portion adapted to overlie the rim of the container and a cylindrical tubular boss formed with an outwardly convex circumferential bulge or bead of arcuate profile. The inner wall of the container mouth is provided with a plurality of spaced-apart inwardly projecting circumferential beads or bulges of arcuate profile and progressively increasing elevation inwardly from the rim, the bead of the cap resting behind the last or innermost bead of the container mouth in a sealing position of the cap.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
161 words
In combination, a closeable container of resiliently yieldable plastic material having a circular edge portion defining a circular opening having an internal wall surface leading to the interior of said container, and a closure means comprising a lid member for covering said opening and having a circular wall projection extending from the peripheral regions thereof with clearance from said opening when positioned in said opening, characterized by the feature that an outwardly extending radiused enlargement is formed on the free end of said projection of slightly larger outside diameter than the internal diameter of said wall surface, and that a plurality of radiused beads are provided around the internal wall surface approximate said opening and are found between the radiused enlargement and said lid member when said lid is inserted as closure over said opening; the inner limiting surfaces of said beads being defined by an imaginary line of rotation the diameter of which diminishes towards the interior of the container.
Claim 2
Dependent Claim
161 words
In combination, a closeable container of resiliently yieldable plastic material having a circular edge portion defining a circular opening having an internal wall surface leading to the interior of said container, and a closure means comprising a lid member for covering said opening and having a circular wall projection extending from the peripheral regions thereof with clearance from said opening when positioned in said opening, characterized by the feature that an outwardly extending radiused enlargement is formed on the free end of said projection of slightly larger outside diameter than the internal diameter of said wall surface, and that a plurality of radiused beads are provided around the internal wall surface approximate said opening and are found between the radiused enlargement and said lid member when said lid is inserted as closure over said opening; the inner limiting surfaces of said beads being defined by an imaginary line of rotation the diameter of which diminishes towards the interior of the container.
Claim 3
Dependent Claim
27 words
A container according to claim 1 wherein the bead farthest from the opening is substantially supported against the enlargement when the lid is inserted in said opening.
