ABSTRACT OF THE DISCLOSURE A child's drinking cup has a lid combining positively interengaging latches with a biasing feature which forces the lid upward with respect to the container in order to more firmly effect latching. A series of projections formed along the interior upper periphery of the container register with latching slots formed along the outer surface of a skirt which depends from the lid, which is dimensioned to fit closely within the opening of the container. An annular flange extends from the outermost periphery of the lid to overlap a portion of the skirt. The outer upper periphery of the container is tapered outwardly to force the flange to flex when the lid is placed on the container thus imparting an upward force to the lid and, thereby, to the lug-and-latch combinations when the lid is turned to register the lugs with the latches.
