Abstract
Abstract A cap for closing said container includes a cover section comprised of a central flat portion and a sloping edge portion sloping downwardly and radially outwardly from said central flat portion. A generally inverted U-shaped seating section receives an upper lip section of the sidewall portion of said container. The seating section includes a generally upright wall portion which is integral at its lower end with, and somewhat rigidified by, the sloping edge portion of the cover section, and which has a length sufficient to project into the container on the inner side of the sidewall portion to a location adjacent an external interlock projection on the container. An outer, circumferentially extending, depending skirt portion embraces the outer side of the container sidewall. A tear strip portion of the skirt is contiguous with and depends from a main body of the skirt for a substantial circumferential extent of the main body, which extent terminates at a section of the main body thicker than, integral with and forming a circumferential continuation of the tear strip. An inwardly facing circumferentially extending sealing groove, defining the juncture of the main body and the tear strip depending therefrom, interlocks with an interlock projection of said container.

Claim 2
Dependent Claim
348 words
Apparatus comprising: a container including: a bottom wall portion, a circumferentially extending sidewall portion terminating at an open upper end defining an upper container edge, and a circumferentially extending, interlock projection on said sidewall portion adjacent said open upper end of said container, said interlock projection facing outwardly of said sidewall portion and dividing said sidewall portion into: an upper, lip section terminating in said upper container edge, and a lower section extending to said bottom wall portion of said container; a cap for closing said container, said cap including: a cover section comprising: a central flat portion, and a sloping edge portion sloping downwardly and radially outwardly from said central flat portion, and a generally inverted U-shaped seating section for receiving said upper lip section of said sidewall portion of said container, said seating section comprising: a generally upright wall portion integral at its lower end with said sloping edge portion of said cover section and rigidified thereby at its juncture with said sloping edge portion, said generally upright wall portion being of a length sufficient to project into said container on the inner side of said sidewall portion by substantially the depth of said lip section, and an outer, circumferentially extending, depending skirt portion for embracing the outer side of said container sidewall portion, said skirt portion including: a main body, a tear strip contiguous with and depending from said main body for a substantial circumferential extent of said main body, which extent terminates at a section of said main body thicker than, integral with and forming a circumferential continuation of said tear strip, and an inwardly facing circumferentially extending groove, defining the juncture of said main body and the tear strip depending therefrom, for interlocking with said interlock projection of said container; said rigidified juncture of said generally upright wall portion of said seating section and said sloping edge portion of said cover section being disposed adjacent said circumferentially extending interlock groove to enhance maintenance of a positive seal at the location of said interlock projection of said container and said groove of said cap.
Claim 3
Dependent Claim
268 words
A cap for closing a container having a circumferentially extending interlock projection, said cap including: a cover section comprising: a central flat portion, and a sloping edge portion sloping downwardly and radially outwardly from said central flat portion, and a generally inverted U-shaped seating section for receiving an upper sidewall portion of said container, said seating section comprising: a generally upright wall portion integral at its lower end with said sloping edge portion of said cover section and rigidified thereby at its juncture with said sloping edge portion, said generally upright wall portion being of a length sufficient to project into said container on the inner side of said sidewall portion to the depth of said interlock projection, and an outer, circumferentially extending, depending skirt portion for embracing the outer side of the container sidewall portion, said skirt portion including: a main body, a tear strip contiguous with and depending from said main body for a substantial circumferential extent of said main body, which extent terminates at a section of said main body thicker than, integral with and forming a circumferential continuation of said tear strip, and an inwardly facing circumferentially extending groove, defining the juncture of said main body and the tear strip depending therefrom, foR interlocking with said interlock projection of said container; said rigidified juncture of said generally upright wall portion of said seating section and said sloping edge portion of said cover section being disposed adjacent said circumferentially extending interlock groove to enhance maintenance of a positive seal at the location of said interlock projection of said container and said groove of said cap.
