A container and cap assembly for holding cosmetic material and the like has a container molded from a plastic material with a generally noncircular configuration defined by a main body member with an upwardly extending neck member thereon. The neck member is provided with a pair of integrally formed exterior double lead threads emanating from an enlarged base portion of the neck member and forming abutment end walls therewith. The cap assembly has an outer shroud member with a noncircular configuration identical to the noncircular configuration of main body member mounted on a head member having integrally formed interior double lead threads with leading abutment end surfaces thereon. The double lead threads of the neck member and head member are designed for mating engagement whereby the abutment end walls and the abutment end surfaces thereof engage when the cap assembly is in its closed or sealing condition on the container to circumferentially align the parts. The mating threads are provided with pitch down regions while the container and cap assembly are provided with abutting projections to restrain reverse rotation or removal of the cap assembly from the container.
