US Classification:

229 25R

Abstract:

A dual compartment sandwich package fabricated of foamed polystyrene or the like and adapted to retain therein in appealing and acceptable form a sandwich including a hot meat portion, such as a hamburger, and a cool trimmings portion, such as lettuce and tomato. The package includes a base and cover having central rib means for rigidifying the package and preventing bending about the longitudinal and transverse axes thereof. There are four cooperating slots and tabs for temporary or secure locking of the cover to the base, which latter condition also forms an external seal to prevent heat exchange with the ambient atmosphere, while the central rib means form an internal barrier to prevent transfer of air and heat between the two compartments. A method of packaging a hot meat portion-cool trimmings portion sandwich, such as a lettuce and tomato hamburger sandwich for dispensing and final assembly by a customer in such a dual compartment package is also disclosed.

US Classification:

206557

Abstract:

A disposable food container comprises a lid and a base optionally connected to each other along a resilient hinge. The lid includes a top wall, a continuous lid side wall, and a plurality of lid corners. The lid side wall encompasses the top wall and extends downwardly and outwardly from the top wall. The plurality of lid corners are at least partially formed by the lid side wall and include a pair of front lid corners. The base includes a bottom wall, a continuous base side wall, and a plurality of base corners. The base side wall encompasses the bottom wall and extends upwardly and outwardly from the bottom wall. The plurality of base corners are at least partially formed by the base side wall and include a pair of front base corners. If the container is provided with a resilient hinge, the pair of front lid corners and the pair of front base corners are spaced away from the hinge. The container includes a corner latch closure for releasably engaging the lid and the base in a closed position.

Inventors:

Glenn C. Castner - Victor NY

Donald E. Rowe - Newark NY

Assignee:

Tenneco Packaging - Evanston IL

International Classification:

B29C 5132

US Classification:

425183

Abstract:

The invention relates to a mold apparatus and a process for forming a lid latching mechanism in a thermoplastic container. The lid latching mechanism features a large, trapezoidally-shaped opening hole. The trapezoidal shape has been found to reduce the amount of tearing that can occur along the edges of an opening formed during the thermoforming process. The opening is created by the engagement between a fixed shear key mounted in a first mold member and a movable shear key which has a trapezoidally-shaped cutting surface and is mounted in a second mold member. The movable key travels along an inclined path as the mold members close on a preheated thermoplastic sheet to form a container.
