ABSTRACT:
A closure assembly for a container having a snap ring connected to the top of the container and a lid that may be easily attached to and later removed from the ring. The snap ring has a plurality of elongated engaging members with elongated grooves therein integrally formed at an annular inside surface thereof, and equally spaced circumferentially around the ring. The lid has an annular bead at an outer circumferential surface that engages the elongated grooves of the elongated engaging members when the lid is attached to the snap ring. Annular portions of the lid and ring also engage corresponding annular grooves of the lid and ring when the lid is attached to the top of the container, providing a secure seal. The lid may be easily removed from the snap ring by placing the end of a tool under the annular bead of the lid and prying the lid free of the container. Preferably the lid, snap ring and container are injection molded from plastic.
