Abstract: A container having a bottom, a sidewall attached to the bottom and the sidewall terminates in an open end. A closure member can be removably affixed to close the open end. There is a downwardly extending lip on the closure member that has an inner wall surface opposed to an outer wall surface. One of the inner and outer wall surfaces of the lip slidably adjoins one of the inner and outer wall surfaces of the container wall. A groove is formed in each of the adjoining wall surfaces such that when the closure is mated to the container, the grooves are brought into registry with one another and jointly form a locking passageway within which there is received an elongated locking member of a size to be received within the locking passageway to thereby prevent axial movement between the container and the closure member. The closure member further includes a port that communicates the locking passageway with the exterior of the closure member.
