Abstract
Abstract This disclosure is directed to a cover and sealing member primarily for use on cans adapted to contain carbonated beverages or drinks which will go flat once the can has been opened. The cover and sealer comprises a member having spaced apart depending skirt portions to define a circumferentially extending channel with means for frictionally receiving therein the projecting lip portion of the can in sealing relationship therebetween. The cover member is specifically formed to prohibit loss of gas when placed over an opened can wherein the pressure of the gas is utilized to enhance the sealing characteristics of the cover.

Claim 6
Dependent Claim
191 words
In combination with a can having an upright circumscribing end wall and a connected can top extending therebetween wherein said upright end walls extend beyond said can top to define a circumscribing lip about said can top, and said can being adapted to contain gassy fluid, the improvement of a sealing cover to seal an opening formed in said can top comprising a cover member having an imperforated top portion conforming substantially to the shape of said can top, a pair of spaced-apart defining skirt means connected to said imperforated top portion, said skirt means defining an outer skirt and a spaced inner skirt forming a channel therebetween circumscribing the periphery of said imperforated top portion, said channel being adapted to receive the circumscribing lip of said can when the cover member is fitted thereto, means defining a sealing bead formed on one of said skirt means, said sealing bead extending inwardly of and circumscribing said channel to bear against the lip of said can received within said channel to define therewith a gastight seal, and said inner skirt means being disposed contiguous to the inner surface of said circumscribing lip.
Claim 7
Dependent Claim
81 words
