Abstract

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.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 288 words
In combination with a food plate or dish, a food-retaining device for retaining food on said plate or dish and against which food may be urged to force it onto an eating utensil comprising: a radially flexible or radially expansible ring-shaped element having a substantially V-shaped cross section formed by an upper and a lower ring-shaped section of right angular truncated conical configuration with a central aperture therethrough for accommodating the peripheral edge of said plate, said upper section and said lower section being joined at their base to form a peripheral edge whereby said upper section extends inwardly and upwardly relative to the center of said plate and said lower section extends inwardly and downwardly relative to the center of said plate and in divergent relationship to said upper section and terminates in a peripheral edge of lesser diameter than the diameter of said plate or dish; said expansible ring-shaped element being resiliently tensioned so as to normally draw inwardly in diameter to forcibly urge against the plate edge; said ring-shaped element having a transverse split defined between opposing opposite ends of said element that terminate in spaced apart relationship whereby said element is radially expandable against the self-bias of said element normally urged against said plate; said ring-shaped element having a yieldable diameter normally smaller than the diameter of said plate; said lower section having an inner exposed surface in space opposing relationship to the external exposed surface of the plate; and sAid ring-shaped element including said upper and lower sections is composed of a semirigid, plastic material adapted to bend or flex so as to distort said central aperture or opening to accommodate assembly and disassembly of said element on and from said plate respectively.
Claim 2
Dependent Claim 288 words
In combination with a food plate or dish, a food-retaining device for retaining food on said plate or dish and against which food may be urged to force it onto an eating utensil comprising: a radially flexible or radially expansible ring-shaped element having a substantially V-shaped cross section formed by an upper and a lower ring-shaped section of right angular truncated conical configuration with a central aperture therethrough for accommodating the peripheral edge of said plate, said upper section and said lower section being joined at their base to form a peripheral edge whereby said upper section extends inwardly and upwardly relative to the center of said plate and said lower section extends inwardly and downwardly relative to the center of said plate and in divergent relationship to said upper section and terminates in a peripheral edge of lesser diameter than the diameter of said plate or dish; said expansible ring-shaped element being resiliently tensioned so as to normally draw inwardly in diameter to forcibly urge against the plate edge; said ring-shaped element having a transverse split defined between opposing opposite ends of said element that terminate in spaced apart relationship whereby said element is radially expandable against the self-bias of said element normally urged against said plate; said ring-shaped element having a yieldable diameter normally smaller than the diameter of said plate; said lower section having an inner exposed surface in space opposing relationship to the external exposed surface of the plate; and sAid ring-shaped element including said upper and lower sections is composed of a semirigid, plastic material adapted to bend or flex so as to distort said central aperture or opening to accommodate assembly and disassembly of said element on and from said plate respectively.
Claim 3
Dependent Claim 26 words
The invention as defined in claim 1 wherein said ring-shaped element is split such that its ends may be twisted or moved relative to one another.
Claim 4
Dependent Claim 53 words
The invention as defined in claim 2 wherein each of said ends includes a pair of rounded corners spaced apart from said peripheral edge and from one another and adapted to facilitate the insertion and removal of said plate from the inner surface of said upper and said lower sections of said element.
Claim 5
Dependent Claim 18 words
The invention as defined in claim 1 wherein said sectional peripheral edges lie along the same vertical plane.
Claim 6
Dependent Claim 25 words
The invention as defined in claim 1 including said split formed through said upper and lower sections to define opposing and spaced apart terminating ends.
Claim 7
Dependent Claim 27 words
The invention as defined in claim 5 wherein the configuration of said element in plan view substantially corresponds to the configuration in plan view of said plate.
Claim 8
Dependent Claim 47 words
The invention as defined in claim 6 wherein said element composition is characterized by developing a springback force when said opposing terminating ends are moved away from each other, said springback force being sufficient to bias said element into gripping relationship with said plate when assembled thereon.
Claim 9
Dependent Claim 19 words
The invention as defined in claim 7 wherein said device is a single piece construction forming a unitary structure.
Claim 10
Dependent Claim 21 words
The invention as defined in claim 8 wherein the dimensional length of said upper and lower sections are substantially the same.
