Abstract
A container for deli food has a base and a removable lid with male and female locking members extending around the periphery thereof. Stiff tabs extend from the periphery of the base and the lid. The tabs are displaced one from the other for easy opening of the container. The tabs are embossed with visual instructions for unlocking, The base of the container is formed of opaque plastic and the lid is clear plastic. The plastic materials are suitable for placing the container in a warming oven and for reheating the food in a microwave oven.
Claims20
A container for food or the like comprising:
- a relatively thin plastic base having a horizontal flange extending around the periphery thereof;
- a relatively thin clear plastic lid having a horizontal flange extending around the periphery thereof and adapted for engagement with the horizontal flange of said base when said container is in a closed condition, said lid being coated with an anti-fog agent to maintain visibility therethrough even when hot food is contained within the container;
- a male locking member extending around the periphery of one of said flanges, said male locking member comprising, in cross section, a horizontal linear top surface, a first substantially vertical linear member, and a second substantially vertical linear member, said first and second linear members extending upwardly to intersect said top surface and extending outwardly with respect to each other;
- a mating female locking member extending around the periphery of the other flange, said female locking member comprising, in cross section, a horizontal linear top member, a first substantially vertical surface, and a second substantially vertical linear surface, said first and second linear surfaces extending upwardly to intersect said top member and extending outwardly with respect to each other;
- a first stiff tab extending from the periphery of said base;
- and
- a second stiff tab extending from the flange of said lid, said tabs being in proximity to one another and slightly displaced from one another whereby said second substantially vertical linear surface of said female locking member will be separated from said second substantially vertical linear member of said male locking member when said first and second tabs are relatively displaced.
