Abstract

A molded plastic overwrap tray is disclosed having a base and sidewalls. The upper edges of the sidewalls define an upper surface of the tray. The base and sidewalls define a food retaining chamber. Adjacent sidewalls of the tray are connected to one another through a corner reinforcing rib extending from the base to the upper edges of the associated sidewalls. The reinforcing rib defines a channel in communication with the food retaining chamber to provide finger access to food positioned in the food retaining chamber to facilitate removal thereof. Each of the corner ribs provides reinforcement to resist deflection of the upper edges of the sidewalls, whereby an overwrap on the tray is supported by the upper surface of the tray to minimize sagging of the overwrap and prevent the overwrap from coming into contact with food in the food retaining chamber. In another embodiment, a center post is provided having its upper end substantially level with the upper surface of the tray. The post contacts the under surface of the overwrap and assists in preventing contact between the food and the overwrap upon stacking one tray on top of another.

Claims

1. A molded plastic overwrap tray comprising:

a base and sidewalls, each of said sidewalls having end edges and an upper edge, the upper edges of said sidewalls defining an upper surface of said tray;

said base and sidewalls defining a food retaining chamber;

adjacent end edges of adjacent sidewalls of said tray being connected to one another through a corner reinforcing rib;

each of said corner reinforcing ribs extending from said base to the upper edges of the associated sidewalls of said tray and being formed having a wall providing a corner channel in communication with said food retaining chamber;

the corner channel of each of said corner reinforcing ribs being of a size sufficient to permit finger access to food positioned in said food retaining chamber of said tray to facilitate removal thereof; and

the wall of each of said corner reinforcing ribs further providing reinforcement to resist deflection of the upper edges of said sidewalls of said tray;

whereby an overwrap on said tray is supported by the upper surface of said tray to minimize sagging of the overwrap and prevent the overwrap from coming into contact with food in said food retaining chamber.

2. The plastic overwrap tray of claim 1 wherein:

the upper surface of said tray adjacent to the corner channels of said corner reinforcing ribs has a width sufficient to provide enhanced support surfaces at the corners of said tray.

3. The plastic overwrap tray of claim 1 wherein:

said sidewalls have an outer surface, and the upper surface of said tray extends outward beyond the outer surface of said sidewalls.

4. A molded plastic overwrap tray comprising:

a base and sidewalls, each of said sidewalls having end edges and an upper edge, the upper edges of said sidewalls defining the upper surface of said tray;

said base and sidewalls defining a plurality of food retaining chambers, said chambers being free of partitions between one another;

adjacent end edges of adjacent sidewalls of said tray being connected to one another through a corner reinforcing rib;

each of said corner reinforcing ribs extending from said base to the upper edges of the associated sidewalls of said tray and being formed having a wall providing a corner channel in communication with at least one of said food retaining chambers;

the corner channel of each of said corner reinforcing ribs being of a size sufficient to permit finger access to food positioned in the associated food retaining chamber of said tray to facilitate removal thereof; and

the wall of each of said corner reinforcing ribs further providing reinforcement to resist deflection of the upper edges of said sidewalls of said tray;

whereby an overwrap on said tray is supported by the upper surface of said tray to minimize sagging of the overwrap and prevent the overwrap from coming into contact with food in said food retaining chambers.

5. The plastic overwrap tray of claim 4 further comprising:

a center post positioned between said food retaining chambers, said post extending from said base to a point substantially level with the upper surface of said tray; and

said center post contacting the under surface of any overwrap on said tray to prevent contact between the food and the overwrap.

6. The plastic overwrap tray of claim 5 wherein:

each of said sidewalls has an inner surface that slopes outwardly from said base to the upper surface of said tray; and

said center post slopes from said base to the upper surface of said tray, said post having a surface which faces an associated one of said chambers and slopes upwardly at approximately the same angle as does the inner surface of the sidewalls of the associated chamber.

7. The plastic overwrap tray of claim 5 wherein:

the upper surface of said tray adjacent to the corner channels of said corner reinforcing ribs has a width sufficient to provide enhanced support surfaces at the corners of said tray.

8. The plastic overwrap tray of claim 5 wherein:

said sidewalls have an outer surface, and the upper surface of said tray extends outward beyond the outer surface of said sidewalls.

9. The plastic overwrap tray of claim 4 wherein:

the upper surface of said tray adjacent to the corner channels of said corner reinforcing ribs has a width sufficient to provide enhanced support surfaces at the corners of said tray.

10. The plastic overwrap tray of claim 4 wherein:

said sidewalls have an outer surface, and the upper surface of said tray extends outward beyond the outer surface of said sidewalls.
