The rectangular reclosable container assembly includes a rectangular open ended container and a closure member for closing the container. The closure member is depressed to engage the inner surface of the container walls, and the container walls and the depressed wall engaging portions of the closure member are provided with cooperating projecting beads and slots which terminate in spaced relationship to the corners of the container and closure member to vent air at the corners of the assembly. The closure member has a tear away skirt which extends from a bridging section which spaces the skirt from the depressed wall engaging portions of the closure member. An upwardly projecting stacking ridge is formed on the closure member to engage the skirt of like closure members and to receive and retain the sidewalls of the container at the bottom thereof to facilitate stacking.

[ I claim:] [1.] A rectangular, reclosable container assembly comprising:a container having two spaced, opposed container sidewalls having an inner and an outer surface, and two spaced, opposed, container endwall having an inner and outer surface,each container endwall being interconnected with said two spaced container sidewalls by arcuately curved container corner sections to form four rounded container corners having an inner and an outer surface, each curved container corner section being joined at a first end to a container sidewall and at a second end to a container endwalls, the container sidewalls, endwalls and rounded container corner sections defining a container open end,said container sidewalls, endwalls and curved corner sections including a laterally projecting locking lip extending outwardly beyond the outer surfaces of said container sidewalls, endwalls and curved container corner sections adjacent to the open end of the container, the container sidewalls, endwalls and curved container corner sections terminating at the open end of the container in end surfaces which extend across said laterally projecting locking lip and around said container open end, elongate projecting beads formed on the inner surfaces of said container sidewalls and endwalls and extending substantially across the extent thereof but terminating at bead ends before said curved container corner sections, said beads being spaced substantially an equal distance inwardly from the open end of said container, anda container bottom wall connected between said container sidewalls, endwalls and curved container corner sections in spaced relation to said container open end, anda closure member mountable on said container for closing the open end of said container, said closure member including a cover section formed to extend across said container below said projecting bead, when the closure member is applied to said container said cover section having a periphery which is adjacent to said container sidewalls, endwalls and curved container corner sections when said closure member is mounted on said container, a container engaging section extending from the periphery of said cover section, said container engaging section having a container engaging wall formed to engage the inner surfaces of said container sidewalls, endwalls and curved container end sections between said cover section and the end surfaces of said container endwalls, sidewalls and curved container corner sections, said container engaging wall having spaced grooves formed therein for receiving the elongate, projecting beads formed on said container sidewalls and endwalls when said closure member is mounted on said container, and a top wall section extending laterally from said container engaging wall in spaced relationship to said cover section and spaced grooves, said top wall section being formed to overlie the laterally projecting locking lip and to engage and overlie the end surfaces of said container sidewalls, endwalls and curved container corner sections when said closure member is mounted on said container, anda tear off strip attached to said topwall section to extend from said top wall section to a tear off strip lower edge in spaced relationship to said container engaging wall and in engagement with said laterally projecting locking lip and the outer surface of said container sidewalls, endwalls and curved container corner sections when said closure member is mounted on said container, said tear off strip including a locking groove at the juncture of said tear off strip with said top wall section to receive said locking flange lip, said locking groove being formed to provide a thin connecting membrane attaching said tear off strip to said top wall section whereby said connecting membrane can be torn to remove said tear off strip from the top wall section, said tear off strip including indicator grooves formed therein with two spaced indicator grooves positioned at each curved corner section of the container when the closure member is mounted on said container, one of said two spaced indicator grooves being formed to extend adjacent to the first end of a curved container corner section and a second of the indicator grooves being formed to extend adjacent to the second end of the curved container corner section with each such indicator groove extending from said tear off strip lower edge to said joinder membrane and inwardly into said tear off strip to a thin, rupturable membrane which bridges said indicator groove.
