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.
