Abstract
Abstract A closure for a wide mouth glass container having a circumferential bead or enlargement at the finish of the container. A circumferential gasket of resilient material is adapted to contact the inner surface of the container finish and extend outwardly around the circumferential bead. A cap member has a central web portion positioned within the gasket and a peripheral portion which extends upwardly and outwardly around the gasket and the circumferential bead. The surface area of the central portion is greater than the area of a surface defined by a plane passing through the juncture of the central and peripheral portions so that upward pressure on the web tends to increase its diameter and urge it against the interior portion of the gasket.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A closure for a container of the type having a circumferential bead or enlargement at the open end thereof, said closure comprising: a. an annular gasket of resilient material disposed against a portion of the inner surface of the container sidewall and extending upwardly and around the circumferential bead; and b. a cap member having a central portion and a peripheral portion, said cap member central portion being positioned within the container opening so that the juncture of the central and peripheral portions contacts said gasket and said peripheral portion extends upwardly around said gasket and the circumferential bead, said central portion formed inwardly relative to the plane of said juncture and being of greater area than the area of a plan passing through said juncture whereby pressure of the contents of said container tending to flatten the central portion of said cap member applies radially outward sealing force by said juncture against said gasket and container wall.
Claim 2
Dependent Claim
158 words
A closure for a container of the type having a circumferential bead or enlargement at the open end thereof, said closure comprising: a. an annular gasket of resilient material disposed against a portion of the inner surface of the container sidewall and extending upwardly and around the circumferential bead; and b. a cap member having a central portion and a peripheral portion, said cap member central portion being positioned within the container opening so that the juncture of the central and peripheral portions contacts said gasket and said peripheral portion extends upwardly around said gasket and the circumferential bead, said central portion formed inwardly relative to the plane of said juncture and being of greater area than the area of a plan passing through said juncture whereby pressure of the contents of said container tending to flatten the central portion of said cap member applies radially outward sealing force by said juncture against said gasket and container wall.
Claim 3
Dependent Claim
37 words
The closure defined in claim 1 wherein said cap central portion comprises an outer marginal portion extending angularly inwardly from said juncture whereby internal pressure flattens said angular marginal portion to exert said radially outward sealing force.
Claim 4
Dependent Claim
37 words
The closure defined in claim 1 wherein said cap central portion is bowed inwardly and wherein said cap peripheral portion has formed therein an annular inwardly extending return-bent recess adapted to receive a portion of said gasket.
Claim 5
Dependent Claim
162 words
In combination, a container having a circumferential bead or enlargement at the open end thereof, and a closure for said container comprising: a. an annular gasket of resilient material disposed against a portion of the inner surface of the sidewall of said container and extending upwardly and around the circumferential bead; and b. a cap member having a central portion and a peripheral portion, said cap member central portion being positioned within the opening of said container so that the juncture of the central and peripheral portions contacts said gasket and said peripheral portion extends upwardly around said gasket and the circumferential bead, said central portion formed inwardly relative to the plane of said juncture and being of greater area than the area of a plane passing through said juncture whereby pressure of the contents of said container tending to flatten the central portion of said cap member applies radially outward sealing force by said juncture against said gasket and container wall.
Claim 6
Dependent Claim
162 words
In combination, a container having a circumferential bead or enlargement at the open end thereof, and a closure for said container comprising: a. an annular gasket of resilient material disposed against a portion of the inner surface of the sidewall of said container and extending upwardly and around the circumferential bead; and b. a cap member having a central portion and a peripheral portion, said cap member central portion being positioned within the opening of said container so that the juncture of the central and peripheral portions contacts said gasket and said peripheral portion extends upwardly around said gasket and the circumferential bead, said central portion formed inwardly relative to the plane of said juncture and being of greater area than the area of a plane passing through said juncture whereby pressure of the contents of said container tending to flatten the central portion of said cap member applies radially outward sealing force by said juncture against said gasket and container wall.
Claim 7
Dependent Claim
37 words
The combination defined in claim 4 wherein said cap central portion comprises an outer marginal portion extending angularly inwardly from said juncture whereby internal pressure flattens said angular marginal portion to exert said radially outward sealing force.
Claim 8
Dependent Claim
37 words
The combination defined in claim 4 wherein said cap central portion is bowed inwardly and wherein said cap peripheral portion has formed therein an annular inwardly extending return-bent recess adapted to receive a portion of said gasket.
