An eating plate (2) for use by the manually impaired has an inclined section (9) leading from the inner bottom (4) of the plate to a curved inner wall (8). The curved inner wall terminates in an inner lip (10) and the inner lip terminates in an outwardly extending inclined section (12) forming the ledge of the plate. The inclined sections, the curved inner wall and the inner lip are optimally formed to cooperate in assisting a user in bringing the food to the edge of the plate with an eating utensil while preventing spills, and thus making eating a more enjoyable and satisfying experience for those who have need for such plates.

BACKGROUND OF THE INVENTION
Eating plates having contoured inner walls are designed for use by the manually impaired as an aid in self-feeding. The inner walls of such plates are designed to act as an extra implement against which the user can trap particles of food. The inner wall acts to hold the food particles on the plate while the user brings an eating utensil such as a fork, spoon or the like, toward the plate edge, and thereby prevents spills and makes eating a much more enjoy­able experience for those who have need for such plates.
It has been found that the inner wall must be contoured so as to assist the user in depositing food directly onto the eating utensil without the user having fine motor control of the hand as would otherwise be necessary. Further, the inner wall contour must obviate the necessity for complex muscle control patterns for accomplishing the eating function. That is to say, the contour must be such that food can be pushed sideways in one plane of movement and be deposited on the spoon or other eating utensil. Otherwise complex secondary sideways and twisting motions would be necessary to accomplish the eating task, with said complex motions, while being within the capabilities of those with normal manual dex­terity, not being within the capabilities of those having need for the plate herein described.
Prior to the present invention attempts have been made to provide plates having curved inner walls to satisfy the above requirements. One such plate is described in U.S. Design Patent 226,674 issued to Nicholas J. Bruno on April 10, 1973, and assigned to Maddak, Inc., assignee of the present invention. However, the plate of the aforenoted design only generally addresses the problem to be solved and does not teach or suggest the particular structural arrangement disclosed herein.
Accordingly, it is the object of the present invention to provide an eating plate for use by the manually impaired, having an inner wall of a particular contoured configuration so as to render said plate use­ful to those with less than fine manual motor control and who are incapable of performing normal motion patterns necessary to accomplish an eating task.

SUMMARY OF THE INVENTION
This invention contemplates an eating plate for use by the manually impaired, having a concavely curved inner wall extending around the circumference of the plate. The inner bottom of the plate has an angularly extending section which meets the bottom of the curved inner wall. The top of the curved inner wall terminates in an inwardly extending lip. The inwardly extending lip terminates in an angularly extending section which forms a plate ledge. The arrangement is such that the angularly extending sections extend at predetermined optimal angles to provide maximum assistance to the user of the plate in depositing food on an eating uten­sil. The radii of the curved inner wall and inwardly extending lip are optimally predetermined to effectively accomplish the eating task.

BRIEF DESCRIPTION OF THE DRAWING
- Figure 1 is a top plan view of a plate according to the invention.
- Figure 2 is a sectional view taken along line 2-2 in Figure 1.

DETAILED DESCRIPTION OF THE INVENTION
With reference to the drawing, an eating plate which may be of a molded plastic such as polypropylene is designated generally by the numeral 2. Plate 2 has an inner bottom 4 and an inner wall designated generally by the numeral 6. Inner wall 6 has a concavely curved portion 8 extending around the circumference thereof and terminating at its bottom in a section 9 which extends angularly upward from inner bottom 4. The top of concavely curved portion 8 terminates in an inner lip 10. Inner lip 10 terminates in a ledge section 12 extending angularly upward therefrom.
It will be understood that when using the dis­closed plate as intended, as an aid for the manually impaired in self-feeding, curved portion 8 of inner wall 6, angularly extending section 9, inner lip 10 and ledge section 12 help to keep the food on the plate when the user brings food toward the edge 14 of the plate via an eating utensil. Spilling of food from the utensil is thereby avoided and easier access thereto is provided. In effect, curved portion 8, sections 9 and 12 and lip 10 function as an extra utensil to accomplish the purposes intended.
Angularly extending section 9 extends upward from plate bottom 4 by an angle A which is optimally ten degrees. It has been found that this configuration assists the user in pushing food up inner wall 6 of the plate. A larger angle would result in sliding of the food toward bottom 4 of the plate to avoid the purpose of the invention as will now be understood.
It has also been found that the radius R₁ of curved inner portion 8 is optimally between one-­quarter and nine thirty-seconds of an inch. A smaller radius would not impart the necessary lift to the food to deposit it in or on the eating utensil, as the case may be, while a larger radius would create, in effect, a wall for blocking food and trapping it in one location, and thereby avoiding the purpose of the invention.
Ledge section 12 extends upwardly by an angle B which is optimally at least five degrees. It has been found that a smaller angle would result in food being deposited on the ledge to likewise avoide the purpose of the invention.
Inner lip 10 extends inwardly from the top of concavely curved portion 8 by an angle C which is optimally forty-five degrees. The inner lip has a radius R₂ which is optimally nine sixty-fourths of an inch. It has been found that this configuration effectively assists the user in bringing food up inner wall 6 of plate 2 to edge 14 of the plate to facilitate the eating process as aforenoted.
In summary, the plate herein disclosed is configured so as to be of assistance for use by the manually impaired as a aid in self-feeding. Section 9 is optimally inclined to assist the user in pushing food up from the bottom of the plate and radius R₁ is optimally formed to provide the lift to deposit food on an eating utensil without acting as a blocking wall and trapping food in one lo­cation on the plate. Radius R₂ helps to facilitate the eating process as aforenoted. Section 12 is optimally inclined to prevent food from being deposited on the plate ledge as is undesirable.
