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.

A container comprising: a receptacle and a cover each of which includes a unitary member molded from plastic; said receptacle member including a round side wall and a bottom wall; said side wall including an upper end having a round upper edge that defines an open end of the receptacle; the side wall also including a lower end that is closed by the bottom wall to define a closed end of the receptacle; the upper end of the side wall having round inner and outer surfaces one of which includes a helical thread; said cover member including an upper wall and an annular lip that extends downwardly from the upper wall and has a round lower edge; said cover lip having round inner and outer surfaces one of which includes a helical thread for mating with the helical thread of the receptacle to secure the cover on the receptacle; said helical threads being movable into mating engagement with each other by threading upon relative rotation between the cover and the receptacle or by flexing of the receptacle side wall and the cover lip upon downward movement of the cover over the receptacle; a retainer located on one of the members in a spaced and opposed relationship to the round surface thereof on which the helical thread thereof is mounted; and said retainer opening vertically to receive the round edge of the other member upon securement of the cover to prevent lateral movement between the upper end of the receptacle side wall and the cover lip in order to maintain engagement of the helical threads.
