Abstract
Ant-free dishes for use by pets comprising, a lower dish positionable in a horizontal plane and defining a lower liquid reservoir therein; an upper food containing section comprising one or more upper dishes disposed vertically and in parallel relationship above the lower dish; and a support member extending vertically between the lower dish and the upper food containing section wherein the support member allows for the lower dish and the upper food containing section to be maintained in fixed vertical alignment thereto.
Claims3
An ant-free dish for use by pets comprising:
- a lower dish positionable in a horizontal plane and defining a lower liquid reservoir therein, the lower dish having an upwardly extending projection about the center of the dish with an axial bore therethrough;
- an upper food containing section comprising a horizontally disposed upper base member having an undulant periphery with a plurality of protrusions disposed thereon and extending outwardly in a spaced, equidistant, generally circumferential and symmetrical relationship relative to the center of the base member and between each undulation, a downwardly extending projection with an axial bore therein being disposed about the center of the upper base member, each protrusion containing a circular aperture of a diameter adapted to encompass a circular food dish therein, the food dish having a circular plate, an upwardly extending peripheral wall, and an outwardly extending annular flange at the upper terminus of the wall adapted to hold the food dish in proximate relationship to the base member upon the placement of the food dish with an aperture thereof;
- a support member comprising a cylindrical tube having an unthreaded upper extent of a diameter to receive the projection of the upper base member, an unthreaded lower end of a diameter to receive the projection of the lower dish, and a threaded central extent therebetween;
- and
- a lower bolt extending through the axial bore of the lower dish and into the threaded central extent of the tube and an upper bolt extending through the axial bore of the upper base member and into the threaded central extent of the tube such that the upper base member and lower dish are maintained in fixed vertical alignment thereto.

An ant-free dish for use by pets comprising:
- a lower dish positionable in a horizontal plane and defining a lower liquid reservoir therein, the lower dish having an upwardly extending projection about the center of the dish with an axial bore therethrough;
- a horizontally disposed rotatable upper circular dish disposed vertically and in parallel relationship above the lower dish, the upper circular dish having upstanding walls across the diameter and about the periphery thereof, thus defining a plurality of wedge-shaped upper partitions therein, a downwardly extending projection with an axial bore therein being disposed about the center thereof, and a demountable cover member disposed thereover having a cutout which selectively exposes a single partition, the upper disk fixedly held about a stationary axial shaft extending downwardly through the center thereof such that it is rotatable about the vertical axis of the shaft;
- a support member extending vertically between the lower dish and the upper dish wherein the support member contains an upper extent which receivingly engages the projection of the upper dish and a lower extent which receivingly engages the projection of the lower dish such that the support member allows for the lower dish and the upper dish to be maintained in fixed vertical alignment thereto.

- and the stationary axial shaft connecting the motor assembly with the upper circular dish in parallel linkage;
- the upper dish further comprising along the bottom periphery thereof, a toothed ring gear in cooperating mesh with the idler gear of the motor assembly.
