Abstract

A clam shell plastic container includes a rectangular container body with a floor and tapered sides and an integral lid. The container body and lid are thermoformed in one piece and in an open configuration. A first hinge along the side of the container body between the container body and the lid allows the lid to rotate into a closed position on the container body. A tear strip adjacent the first hinge allows a user to separate the lid from the container body to open the container body. After separation the lid is relocked to the container body along the side opposite the first hinge and a second hinge along this opposite side is used thereafter to open the container.
