Abstract: A container assembly as a lid for closing and sealing the open end of the container. The container includes an outwardly curled sealing lip at its upper most periphery. The lid includes a rim having inner and out legs, and a bridge or web connecting the legs. The legs and the bridge define a downwardly opening channel proportioned to fit over the lip of the container. The legs, bridge and the lip cooperatively define therebetween a sealant cavity or the cavity may be formed only in the bridge. The sealant cavity includes a sealing material received therein. The lid further includes contact surface means. The contact surface means selectively contact the container lip to limit the minimum size of the cavity when the lid is pressed onto the container. By limiting the minimum size of the cavity, over compression of the sealing material is avoided during application of an excessive load on the container lid.

Abstract: A container assembly comprising a container open at one end and closed at the other end by a bottom wall, and a closure or lid for closing the open end of the container. The container includes a lip which allows the lid to be utilized either with or without a gasket or sealing material. The closure is bounded by a rim having a protruding hook for engaging the lip of the container and securing the lid on the container. In a preferred embodiment the lip includes an upper detent or horizontally extending arm for engaging the hook of the closure at a first position relative to the sidewall when sealing material is employed with the closure. The lip also includes a lower detent or downwardly extending arm spaced beneath the upper detent for engaging the closure at a second position relative to the sidewall when sealing material is not employed with the closure.
