A container (10) disclosed includes a unitary receptacle (12) and a unitary cover (14) which are each molded from resilient plastic with segmented buttress retainers (24, 32) that cooperate to secure the cover upon a snap action closing movement while permitting opening cover movement by manual rotation. The container has particular utility as a paint pail for holding paint, stain, or the like but is also useful for holding food or other contents. An upper open end on a side wall (16) of the receptacle has a round surface (22) on which circumferentially spaced sets of the buttress retainers (24) are located with horizontal retaining flanks thereof facing downwardly and inclined flanks thereof extending downwardly and radially to the associated retaining flanks. An annular lip (28) of the cover extends downwardly from an upper wall (26) thereof and has a round surface (30) on which circumferentially spaced sets of buttress retainers (32) are located with horizontal retaining flanks thereof facing upwardly and inclined flanks thereof extending radially and upwardly to the associated retaining flanks. Downward cover movement slidably engages the inclined flanks on the retainers of the cover with the inclined flanks on the retainers of the receptacle to provide the snap action that engages the retaining flanks to secure the cover while permitting subsequent opening movement by cover rotation. A groove (42) in the cover adjacent the juncture of its upper wall (26) and lip (28) receives a seal (44) that is engaged by the upper end of the receptacle to seal the container when the cover is secured. A reinforcing rib (46) and handle lug (48) construction on the upper end of the receptacle side wall is also provided as is a receptacle rib (58) and cover recess (59) stacking construction. |
