ABSTRACT:
A container (20) disclosed includes a receptacle (22) and a cover (24) each of which includes a unitary member (26,28) molded from plastic. A helical thread (44) on the upper end of the receptacle side wall (30) and a helical thread (58) on a downwardly projecting lip (50) of the cover are engaged with each other in mating relationship by either threading of the cover onto the receptacle or by downward movement as the receptacle side wall and the cover lip flex to permit such engagement by a snap action. A retainer (46) on the receptacle side wall receives the lower edge (52) of the cover lip and a retainer (60) on the cover receives the upper edge (36) of the receptacle side wall so as to maintain the mating relationship of the threads with the cover in its closed position. The container has particular utility for use as a paint container especially when utilized with specific constructional features disclosed.
