Abstract

A self-cleaning cat waste disposal device having a portable suitcase style container structure with two substantially identical compartments pivotally connected together along one edge thereof and latchable together by a three-way handle along an opposite edge thereof. A pivotally mounted screen unit is included between the container compartments and latchable to one or the other by the handle structure. The handle structure functions in a three-way manner and permits the screen unit and the two container units to be all three firmly latched together, or the screen unit to be positively latched to one container unit or the other. One embodiment of the device provides for a single removable trap unit associated with the pivotal connection for both the container compartments and with a guide funnel arrangement for catching waste from one of the compartments or the other when the device is being operated. Another embodiment provides for a removable trap unit associated with each of the respective container compartments. Appropriate detent retention features for the trap units are also provided, as well as guide channel structure between the edges of the screen unit and the inside lip of the container units for retaining kitty litter as used with this device therewithin.

Dependent claims

An animal waste collection and disposal device which contains a litter material into which animal waste matter is deposited, the device comprising:

a pair of opposed housing members, each housing member having wall portions defining a litter-receiving chamber which is open over at least portions of one major planar face of said housing member;
means for joining the housing members together for angular movement relative to each other, the open portions of the litter-receiving chambers facing each other on movement of said housing members together to form a substantially closed housing;
a screen carried by the housing and adapted to be displaced with and relative to each of the housing members, the screen surmounting the open portion of each litter-receiving chamber when displaced into adjacent relation to each one of said housing members;
and,
waste receiving means carried by the housing for receiving waste matter contained within either of the litter-receiving chambers, whereby waste matter deposited in litter in one of the litter-receiving chambers in one housing member is trapped against the facing side of the screen on closure of the housing members together and inversion of the housing, the litter in said one chamber passing through the screen into the other chamber in the other housing member, the waste matter being displaced from the screen into a receptive proximity to the waste receiving means on angular displacement of the screen and said one housing member into a substantially tilted or vertical orientation.
