Abstract:
1. A container/cover assembly for containing a liquid substance and which provides protection against a toddler drowning as a result of falling into the container when its cover has been removed, said assembly comprising: a container having an open top end and a closed bottom end defined by a side wall and a bottom wall formed integral with the side wall, said side wall being circular in cross-section and having a maximum diameter at said top end and said container having a height that substantially exceeds the magnitude of said maximum diameter, said bottom wall being characterized by an annular protuberance concentric with said side wall and surrounding a recessed section of said bottom wall, said annular protuberance being an integral extension of said side wall and having a curved convex shape in cross-section that extends from said recessed section to said side wall, the diameter of said recessed section and the radius of curvature of said convex shape in cross-section being sized so that when the container is placed top end up on a floor or other supporting surface a circumferentially-extending portion of said annular protuberance located between said side wall and said recessed section will make a circular line contact with said floor or other supporting surface, with said circular line contact having a diameter that does not exceed said maximum diameter so that in the event that a toddler should fall head first into the open container while the container contains a liquid, the weight of the toddler exerted on the top end of the container will cause the container to tip over so as to spill the liquid and prevent the toddler from drowning; and a cover for closing off said open top end of said container, said cover being characterized by a rim section and a crown section surrounded by said rim section, said rim section being adapted to make a locking connection with said side wall of said container, and said crown section being characterized by an annular portion in the form of a concave depression having a curved cross-sectional configuration such that said annular protuberance of another like container will make a close fit in said depression.
