## Title
Pet feeding system and method of use

## Abstract

A pet feeding system includes a dish having an upwardly projecting elongated handle. A liner is shaped and dimensioned to fit over the dish. An anti-rotation mechanism prevents the liner from rotating with respect to the dish.

## Background
TECHNICAL FIELD
The present invention pertains generally to the feeding of pets, and more particularly to a pet feeding system which has a dish with a handle, and single use liners which fit over the dish.
BACKGROUND OF THE INVENTION
Pet food is typically put in dishes which are placed on the floor thereby allowing the pet to eat or drink. The dish must be cleaned after each use to maintain sanitary conditions. Also, the elderly or physically disabled can experience difficulty in both lowering the dish to the floor and raising the dish from the floor.
BRIEF SUMMARY OF THE INVENTION
The present invention is directed to a pet feeding system which enhances the clean up process, and also has a long handle which eases the process of placing and picking up the dish. The pet feeding system of the present invention includes a feeding dish to which is attached an elongated upwardly projecting handle. The handle allows a person to conveniently lower the dish to the floor and raise the dish from the floor. Additionally, the pet feeding system includes a disposable single use liner which is placed over the dish. The liner is shaped and dimensioned to fit closely over the dish. An anti-rotation mechanism prevents the liner from rotating as the pet consumes food from the lined dish. In one embodiment of the invention, the anti-rotation mechanism consists of the liner having a notch or cutout for receiving the handle. With the handle disposed in the notch, the liner cannot rotate with respect to the dish. When the pet has finished eating, the liner is removed and discarded. The liner is constructed of paper or a polymer similar to a disposable plate.
In accordance with a preferred embodiment of the invention, a pet feeding system includes a dish. An upwardly projecting handle is connected to the dish. A liner is shaped and dimensioned to fit over the dish, and an anti-rotation mechanism prevents the liner from rotating with respect to the dish.
In accordance with an aspect of the invention, the anti-rotation mechanism includes a notch in the liner engaging the handle so that the liner cannot rotate in the dish.
In accordance with another aspect of the invention, the anti-rotation mechanism includes the liner having a plurality of spaced apart cavities which can engage a portion of the handle which is disposed on the side of the dish.
In accordance with another aspect of the invention, the anti-rotation mechanism includes the liner having an aperture which is engaged by a protuberance on the dish.
In accordance with another aspect of the invention, the anti-rotation mechanism includes the dish having an aperture which is engaged by a protuberance on the liner.
In accordance with another aspect of the invention, the liner has a saddle-shaped lip which is disposed above the notch and surrounds the base of the handle.
In accordance with another aspect of the invention, the handle is oriented at an angle of about 25° with the vertical.
Other aspects of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION
Referring initially to FIG. 1, there is illustrated an exploded perspective view of a pet feeding system in accordance with the present invention, generally designated as 20. Pet feeding system 20 includes a dish 22 which is of a standard size and shape. An elongated handle 24 is connected to dish 22 and upwardly projects therefrom. In an embodiment of the invention, dish 24 has a side 26 and handle 24 is connected to side 26. In the shown embodiment, handle 24 is integrally connected to dish 24, however it may also be appreciated that handle 24 could be attached by mechanical means such as screws. Dish 22 also has a bottom flange 27.
Pet feeding system 20 further includes a liner 28 which shaped and dimensioned to fit over dish 22 (refer also to FIG. 2). Liner 28 is the same shape as dish 22 and slightly larger so that it fits closely over dish 22. Liner 28 has an upwardly curved outside rim 32 which is useful in catching spilled food.
Pet feeding system 20 further includes an anti-rotation mechanism for preventing rotation of liner 28 with respect to dish 22. In the shown embodiment, the anti-rotation mechanism includes dish 22 having a side 26 with handle 24 connected to side 26. Liner 28 has a side 34 on which a notch 30 for receiving handle 24 is disposed. It is noted that as used herein the term “anti-rotation mechanism” means that liner 28 cannot freely rotate with respect to dish 22. A slight amount of rotation due to component tolerances is always possible.
FIG. 2 is a perspective view of pet feeding system 20 with dish 22 residing upon a support surface 500 such as a floor. Before being placed on support surface 500, liner 28 has been downwardly placed over dish 22 with liner outside rim 32 covering bottom flange 27 (refer to FIG. 1). When liner 28 is placed over dish 22, notch 30 engages (receives) handle 24, and thereby prevents liner 28 from rotating with respect to dish 22 about dish central axis 25.
FIGS. 3 and 4 are top plan and side elevation views respectively of dish 22 and handle 24 showing side 26, bottom flange 27, and central axis 25. In an embodiment of the invention, handle 24 is oriented at an angle A of about 25° with the vertical. In another embodiment of the invention, handle 24 has a length L of about 20 to 30 inches. The inside surface of dish 22 is shown by dashed line 34.
FIGS. 5 and 6 are top plan and side elevation views respectively of liner 28, showing notch 30 and outside rim 32. The inside surface of liner 28 is shown by dashed line 36.
FIG. 7 is a side elevation view showing a plurality of liners 28 stacked in nested relationship (similar to the stacking of paper plates).
FIGS. 8, 9, and 10 are top plan, side elevation, and rotated fragmented side elevation views respectively of a second embodiment of liner 28. In this embodiment, liner 28 has a saddle-shaped lip 40 disposed above notch 30. Lip 40 is shaped and dimensioned to surround the base portion of handle 24 (refer to FIG. 4). As such, lip 40 protects handle 24 from spilled food and thereby keeps it clean.
FIG. 11 is an enlarged perspective view of liner 28 showing saddle-shaped lip 40 residing above notch 30
FIG. 12 is an exploded perspective view of another embodiment of pet feeding system 20. In this embodiment the anti-rotation mechanism includes dish 22 having side 26 and handle 24 connected to side 26 and forming a protuberance 42 thereon. Liner 28 has side 34 which has a plurality of circumferentially spaced apart cavities 44, each cavity 44 being shaped and dimensioned to receive protuberance 42 on side 26 of dish 22 and thereby prevent rotation of liner 28 with respect to dish 22.
FIG. 13 is an exploded perspective view of another embodiment of the pet feeding system 20. In this embodiment the anti-rotation mechanism includes dish 22 having side 26 with a protuberance 46 disposed on side 26. Liner 28 has side 34 upon which an aperture 48 is disposed. Aperture 48 is shaped and dimensioned to receive protuberance 46 on side 26 of dish 22 and thereby prevent rotation of liner 28 with respect to dish 22.
FIG. 14 is an exploded perspective view of another embodiment of pet feeding system 20. In this embodiment the anti-rotation mechanism includes dish 22 having side 26 with an aperture 50 disposed on side 26. Liner 28 has side 34 upon which an inwardly projecting protuberance 52 is disposed. Protuberance 52 is shaped and dimensioned to be received by aperture 50 on side 26 of dish 22 and thereby prevent rotation of liner 28 with respect to dish 22.
