Patent ID: 6851569

Claim:
A lid/container combination comprising: a molded lid having a central crown portion, a circularly shaped rim portion surrounding said crown portion, mutually spaced locking tabs formed integral with and depending from said rim portion, each locking tab comprising a body portion that depends from said rim and has a bottom end and an enlarged locking portion on said bottom end of said body portion characterized by a shoulder that faces upward and extends both circumferentially and radially of said rim, and latch means projecting from said rim; and a container having an open end, a closed end, a first circumferentially continuous side wall extending from said open end to said closed end, a radially-extending annular wall attached to and surrounding said side wall at said open end, said annular wall having an upper surface, a second side wall attached to and depending from said annular wall, said second side wall being spaced from said first side wall, a plurality of openings in said annular wall, each of said openings comprising a first portion that is wide enough to accept said body portion and said enlarged locking portions of said tabs and a second portion that is wide enough to accommodate said body portion but too narrow to accept said enlarged locking portion, and a plurality of mutually spaced catch members projecting upward from said upper surface in position so that said latch means can releasably engage one of said catch members when said lid is secured to said container; whereby said lid (a) may be coupled to said container by inserting said tabs into said first portions of said holes and (b) may be secured to said container by rotating said lid relative to said container in a direction to shift said tabs so that said shoulders underlie said annular wall and thereby prevent said tabs from being pulled out of said openings, and engagement of said latch means with one of said catch members prevents relative rotation of said lid and container in a direction that would permit removal of said locking tabs from said openings.
