A resealable, cylindrical plastic container assembly formed from high density thermoplastic includes a novel rim and lid interlock construction which provides an improved rim-to-lid seal. The container includes a plurality of circumferential and longitudinal reinforcement ribs adjacent the rim which are inset into the container sidewalls so as to avoid protuberances therefrom. A connecting flange above the reinforcement ribs supports the rim and provides a firm surface for supporting a pry tool used to remove the lid from the container. The rim comprises an exterior sealing bead and an interior locking lip connected by a substantially flat, inclined sealing surface. The lid is provided with interior and exterior locking portions defining a channel which grips and conformingly engages the rim to provide a fluid tight seal between the bead and locking lip of the container. Circumferentially spaced notches in the connecting flange provide access to a pry opening between the flange and the lid to facilitate removal of the lid.

A resealable plastic container assembly, comprising: a generally cylindrical container having a bottom, a sidewall extending upwardly from said bottom and an open top, said container including: (1) a plurality of circumferential reinforcement ribs adjacent said top thereof, said ribs being defined within a radially inset area in said sidewall, the outside diameter of each of said ribs being substantially equal to or less than the outside diameter of said side wall below said inset area, (2) a connecting flange above said circumferential ribs extending upwardly toward said open top, and (3) a rim connected to and disposed above said connecting flange, said rim having an arcuately shaped bead on the upper extremity thereof extending radially outward and defining said open top, a locking lip on the opposite end of said rim and interior of said container, and a substantially flat sealing surface essentially interior of said container and extending between said container and extending said bead and said locking lip to provide a continuous seal between said bead and said locking lip; and, a lid for removable attachment to said container comprising a substantially flat disc having a channel in the periphery thereof adapted to receive said rim therewithin, said channel being defined by－ (1) a substantially flat wall surface adapted to sealingly engage said flat sealing surface and being essentially coextensive with the latter, (2)an interior locking portion on the lower extremity of said flat wall surface and including an arcuately shaped interior locking edge adapted to conformingly grip said locking lip, and (3) an exterior locking portion on the upper extremity of said flat wall surface and including an arcuately shaped exterior locking edge adapted to conformingly engage and grip said bead, said exterior locking edge being spaced from said connecting flange to define a pry opening between said lid and said container rim into which a tool may be inserted for removing said lid, said rim and said channel providing a tight, continuous lid-to-container seal between said exterior and interior locking portions of said lid.
