Abstract

A pet drinking aid includes a cap defining an axial passage therewithin. Preferred embodiments of the cap include securing means for detachably securing the cap to a fluid container and an inwardly directed flange. The securing structure may include helical threads, an elastomeric sleeve or the like. The cap further includes a ball positioned within the axial passage of said cap and, in a preferred embodiment a biasing structure mounted relative to the cap within the axial passage. The biasing structure advantageously engages the ball to bias the ball toward the inwardly directed flange. The ball is preferably captured within the axial passage between the inwardly directed flange and the biasing structure, and the ball is capable of rotatable movement and limited axial movement against the bias of the biasing structure. The biasing structure may include a compression spring, a foam member or the like. In an alternative embodiment, the biasing means is omitted and the cap includes an inwardly directed ridge extending from the cap'"'"'s inner surface at an axial location intermediate the first and second ends of the cap.
