## Abstract

A watering device for pet animals is disclosed, wherein a sucking pipe is attached to a hermetically sealed water-container, through a suction port of which a pet animal can water any time it likes. Loaded into the sucking pipe is a leak-preventing plug which is provided with a through hole communicating with the water container. With such an arrangement, the pet animals can draw the water in the water container through the through hole of the leak-preventing plug. The leak-preventing plug has on its outer circumferential surface a plurality of collars with the object of hermetically sealing the gap between itself and the sucking pipe.

## Claims

### Claim 1

A watering device for pet animals, which comprises; an elongated sucking pipe extending downwardly from a hermetically sealed water container, and being so configured that pet animals can water from a suction port at the lower end of said sucking pipe; said sucking pipe comprising an elongated hollow cylinder of predetermined internal diameter open at both ends and made of a hard material which is not damaged by biting and chewing and an elongated cylindrical leakage-preventing plug disposed entirely within said hollow cylinder and container and having a longitudinal base of lesser diameter than said predetermined internal diameter, said plug being made of a material susceptible to damage by biting and chewing and being located protectively within said sucking pipe such that it cannot be contacted directly by said animals, said plug having engagement means on its outer surface for retaining it within said cylinder.

### Claim 2 (depends on 1)

A watering device for pet animals as set forth in claim 1, wherein said leakage-preventing plug, has its exit end disposed within said sucking pipe.

### Claim 3 (depends on 1, 2)

A watering device for pet animals as set forth in claim 1 or 2, wherein said leakage-preventing plug is molded of plastic, said engagement means comprise integral collars which engage closely the inner circumferential surface of said sucking pipe.
