Abstract

A food-retaining device adapted for removable mounting to an ordinary food plate. The device comprises a split ring shaped singular piece of flexible material having a substantially Vshaped cross section, adapted to receive and be mounted upon a food plate which is equal to or slightly larger in diameter than the diameter of the device itself. Mounting of the retainer device upon a plate is accomplished via a twisting and/or prying action exerted upon the ends of the split ring and thereupon inserting of the plate therein. When mounted circumferentially around a plate, the upper section of the retainer is disposed such that it slants upwardly and inwardly toward the center of the plate so that the inner surface thereof acts as a barrier to food which is urged against it, and thus prevents spilling of the food over the edge of the plate or the retainer device itself.

FOOD-RETAINING DEVICE BACKGROUND or TI-IE INVENTION 1. Field of the Invention This invention relates in general to a means for retaining food upon a plate and more particularly, to an attachment which, when in place, will provide a barrier against which food on the plate may be urged to facilitate placing the food upon an eating utensil preparatory to eating.

2. Description of the Prior Art Hcretofore, the problem of retaining food upon a plate preparatory to the eating thereof by a child or invalid has always presented a problem Many attempts have been made to overcome this problem but with little success. One such attempt was the compartmentalized plate whereby the plate was segregated into various compartments each one of which was for a specific food. This, however, proved of little success, in that the amount of any particular type of food was necessarily limited by the size of the compartment, and also should the person using the same wish to mix two or more of the various foods, he had to urge the food over the wall into an adjoining compartment.

Another such attempt to overcome the aforementioned problems was to use certain rigid attachments adapted to coincide with the upper edge of the compartmentalized plate and being horizontal thereto, which were either permanently or removably connected to the plate. One such disadvantage of these rigid-type attachments was that there was no manner in which they could be adapted for small or slight differences in the diameter or shape of the various sized plates; Also, when they were attached to the plate by means of screws or bolts, food particles tended to accumulate within the threaded apertures in the plate, thereby preventing or inhibiting the cleaning and sterilization thereof which is so vital to the welfare of a child or invalid. Still another distinct disadvantage of such a device was to significantly reduce the size of the compartment aperture into which a spoon or fork could be inserted, thus tending to make its use rather clumsy or awkward. In addition, because of the horizontal attitude of such an attachment with respect to the plate, food tended to rest upon the upper surface thereof after spilling off the fork or spoon and might thereafter easily fall off the dish.

Still another device which was used with little success was the removably mounted vertical barrier. While this barrier or baffle did, to some extent, prevent food from overflowing the plate it had the inherent disadvantage of covering only a very small arcuate section of tee circumference of the plate. Thus, the overwhelming portion of the plate was neither protected nor usable as a barrier against which food could be urged.

SUMMARY OF THE INVENTION These disadvantages of the prior art have been overcome by the present invention which comprises a split ring-shaped device having a substantially V-shaped cross section adapted to receive and surround the peripheral edge of a food plate or dish. The upper section of the device when mounted to the plate is upwardly and inwardly disposed towards the center of the plate, and is slanted at such an angle that the food urged against the inner surface thereof is easily forced upon the for or spoon of the person using it. v,

While the device may, of course, be fabricated from any suitable material which can be bent or twisted, the preferred material would seem to be light, soft plastic which would not tend to corrode. The terminating ends of the split ring are rounded at their upper and lower corners such that they may more easily facilitate the insertion of the plate within the inner surface thereof with a minimal amount of effort.

It is therefore an object of the present invention to provide a new and improved food-retaining device for use on a plate, platter, saucer, or similar vessel which may be readily applied and removed and which is thoroughly sanitary in all respects.

Another object of the present invention is to provide a foodretaining device which may accommodate various size plates or dishes.

Another object of the present invention is to provide a barrier or baffle of a child's or invalids dish which will aid the former in learning to eat and both to keep the food on the dish.

Another object of the present invention is to provide an easy feeding device adapted to be fabricated entirely of plastic or other light weight flexible material and which is further adapted for mass production techniques thereby making it accessible to the consumer at low cost.

BRIEF DESCRIPTION OF THE DRAWINGS The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings, in which:

FIG. 1 is a perspective view showing the foodretaining means mounted to a food plate;

FIG. 2 is a plan view of the assembly of FIG. I; and

FIG. 3 is a fragmentary vertical section taken on the line 33 of FIG. 2 and showing the food-retaining means mounted on the plate.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the Figures in detail, a food-retaining device in accordance with the present invention is diagrammatically illustrated in the general direction of the arrow [0 and is shown mounted to a standard food plate 12. The food plate 12 comprises a substantially central flat section 14 and an outwardly and upwardly extending toroidally shaped outer section 16 circumferentially disposed around the central section l4 which terminates at a rounded peripheral edge 18.

The food-retaining device 10 is of a generally split ring configuration having a substantially V-shaped cross section formed by an upper section 22 and a lower section 24 which terminate at

ends

26 and 28.

The upper section 22 has a generally truncated right angle conical shape with a central aperture therethrough and defines an outer surface 29 and an inner surface 30. The lower section 24 likewise has a generally truncated right angle conical shape with a base diameter equal to the base diameter of the section 22 and has a central aperture therethrough and defines an outer surface 31 and an inner surface 32.

The

sections

22 and 24 join at their bases of maximum diameter to form a circumferential edge 33 at or near the midpoint of the device 10 and thereafter diverge from one another inwardly toward the center of the device 10.

The upper section 22 when mounted on or carried by the plate 12 is inwardly and upwardly disposed toward tee central portion 14 of the plate 12 while the lower section 24 is downwardly and inwardly disposed thereto.

The

ends

26 and 28 each include a pair of

rounded corners

34 and 36 respectively opposite the circumferential edge 33 to give greater facility for the insertion and removal of the plate 12 from the device 10.

Upon insertion of the plate 12 into the retaining device 10, the plate edge 18 will bear against the

inner surfaces

30 and 32 of the

sections

22 and 24 respectively and are retained in abutting relation thereto by the biasing effect resulting from the slightly larger diameter of the plate 12 as compared with the device 10.

In operation then, the plate 12 is inserted into the foodretaining device 10 by bending or twisting the device 10 until the plate edge I8 bears against the

inner surfaces

30 and 32. The diameter of the plate 12 being equal to or slightly larger than the diameter of the device 10 causes the device 10 to expand slightly and consequently a biasing effect is produced whereby the plate edge 18 is firmly fixed relative to the edge 33. When mounted to the plate 12, the inner surface 30 of the upper section 22 is inwardly and upwardly disposed relative to the central section 14 so as to act as a baffle or barrier to food urged against it.

The lower section 24 is disposed inwardly and downwardly with respect to the central section 14 and terminates at the edge 38 which is of a lesser diameter than the diameter of the plate 12 so that the device will be retained on the plate 12.

It is to be noted that while the material for the device 10 must be resilient enough so that it can be bent or twisted to accept the plate 12, it must also possess sufficient strength to withstand the pressure of food and of the eating utensil bearing against it without having its

ends

26 and 28 separate so far that it will disengage from the plate 12.

While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects, and, therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of this invention.
