Abstract: A container lid assembly is a lid unit for covering an upper-end opening of a container. The lid unit includes a lower connecting member peripherally mounted with a ring, an intermediate covering member, and an upper connecting member stacked in order. When the lid unit covers the container's opening and the upper connecting member is rotated manually, the lower connecting member is driven to move upward so that the ring at the periphery is pushed outward by the lower end of the intermediate covering member and closes the container's opening even more tightly, thereby providing desired sealing for the container.

Abstract: The present invention provides a water container structure, which is a container combination for an animal to drink water and comprises a containing unit, for water to be added, at an upper end and a receiving unit for the animal to drink the water with its mouth at a lower end. A plurality of grooves, spaced up and down, are concaved at two corresponding sides at a predetermined height of the containing unit at the upper end for two projecting portions extending inward at an upside of the receiving unit at the lower end to insert in. A water dispensing amount of the container combination is controlled by installing and screwing the water dispensing device of the containing unit and the upper end on the receiving unit at the lower end by hand to allow to predetermined control of the water dispensing amount.

Abstract: A water-stopping structure for a container is disclosed. A float is provided in an internal space of a guiding element. A rod extending from one end of the float is movably received in a tube which penetrates an upper surface of the guiding element. A limiting element in which a water-stopping ball is movably received is mounted around the tube such that the water-stopping ball can be supported by the rod. A lower section of the guiding element is peripherally provided with grooves for guiding water out. A lower cover is mounted around an annular section concavely provided at a lower end of the guiding element. The water-stopping unit thus formed is connected to the bottom of a bucket and placed on a bottom plate so as to stop water from flowing from the bucket to the bottom plate when a predetermined water level is achieved in the bottom plate.
