The Antser ant-proof barrier is the pesticide-free way to prevent ants from infesting pet-food dishes, garbage cans, recycle bins, sweets and pastries, etc.
To attain this, representative embodiments of the concepts of the present invention are illustrated in the drawings and make use of an ant proof pet dish including a base receptacle, and an intermediate receptacle overlying and completely covering an open top surface of said base receptacle and spaced slightly thereabove. An upper receptacle is supported slightly above the intermediate receptacle. In use, the base receptacle is filled with a fluid such as water or a non toxic insect inhibiting fluid. The intermediate receptacle is filled with water for a pet to drink and the other receptacle is filled with pet food. The animal is prevented from accessing the base receptacle, which forms a fluid filled moat to prevent ants and other crawling insects from accessing the water and food receptacles. An outwardly extending projection may be formed on the base receptacle and provided with a removable cover to enable filling of the base receptacle with a fluid. A plurality of cooperating posts and sockets are utilized to removably secure the receptacles in a parallel slightly spaced relation. An overflow conduit may be provided along with a fluid coupling extending through a side wall of the intermediate receptacle to enable remote and simultaneous filling of both the base and intermediate receptacles.
Various types of pet dishes are known in the prior art. A typical example of an insect inhibiting pet dish is to be found in U.S. Pat. No. 4,007,711, which issued to J. Michael on Feb. 15, 1977. This patent discloses a telescoping variable height pet dish having a central food bowl with a pet operable lid and a annular moat type water trough secured around the central bowl. This construction allows access by the pet to the fluid within the insect inhibiting moat. The animal may thus drain the moat, destroying the insect barrier. U.S. Pat. No. 4,128,080, which issued to C. Haney on Dec. 5, 1978, discloses an insect proof animal dish which includes a food dish supported on a pillar which rises out of the water in the water dish. This patent utilizes the animal's water supply to form the insect inhibiting moat and thus does not prevent insects from contaminating the water dish. U.S. Pat. No. 4,357,905, which issued to R. Carpenter on Nov. 9, 1982, discloses a moated pet feeder which combines a food bowl and a water bowl in side by side relation. The food bowl is surrounded by a moat cavity which fills with water flowing through a substantially horizontal passage connecting the moat cavity with the water bowl to form a moat which inhibits ants and other crawling insects. This construction likewise does not separate the potentially contaminated insect inhibiting moat from the animal's water supply. U.S. Pat. No. 4,399,772, which issued to R. Salinas on Aug. 23, 1983, discloses an animal feeder which includes a bowl which is filled with water in use. An arm extends upwardly from the bowl and has a support for an animal's food dish. This construction likewise does not protect the water supply from crawling insects. U.S. Pat. No. 4,505,228, which issued to J. Scott on Mar. 19, 1985, discloses a dog feeder for protecting and preserving food or fresh water to be made available upon self-initiated action of the dog. An open tray surrounds a vessel in the form of a moat. The moat is not protected from access by the pet.
