  • Patent number: 5107620
    Abstract: An electrified table cloth for preventing crawling insects from gaining access to the consumer's food or drink comprises a cloth formed of electrically insulated material which has at least one pair of parallel electrically conductive strips secured to the edge or border of the cloth to completely encircle the cloth and which are connected to a low voltage DC battery also secured to the cloth. The strips of electrical conductive material are spaced apart sufficiently to normally prevent completion of a circuit across the strips and for completion of a circuit across said strips through an insert's body as the insect attempts to traverse the strips when crawling acorss the edge of the cloth. The current passing through the insect's body is sufficient to produce a sensation which will discourage further travel across the edge of the cloth.

  • Patent number: 4827874
    Abstract: An electrified pet feeding dish for preventing crawling insects from gaining access to the pet's food or water comprises a dish formed of electrically insulated material which has at least one pair of parallel electrically conductive strips secured to the side wall of the dish to completely encircle the dish and which are connected to a low voltage DC battery also secured to the dish. The strips of electrical conductive material are spaced apart sufficient to normally prevent completion of a circuit across the strips and for completion of a circuit across said strips through an insect's body as the insect attempts to traverse the strips when crawling up the side wall. The current passing through the insects body is sufficient to produce a sensation which will discourage further travel up the side wall. A pet or human who may come into contact with the strips will usually not feel the current, and even if the pet or human is wet, the current will produce only a slight tingling sensation.
