Abstract
The present invention consists of an inexpensive tight sealing plastic container suited for microwave cooking, top-shelf dishwashing and freezer use. In accordance with a preferred embodiment, the container is provided with two compartments, one large and one small. The container utilizes a dual cut-back closure device of which the retaining bead of the container bottom maintains the container top in a secure position. The inside dimensions of the container top are slightly larger than the container bottom in both compartments. The difference in sizes provides an interference fit and forms a substantially leak proof seal along the inside perimeter of both compartments of the container. The container top provides at least one gripping tab, which facilitates the separation of the container top from the container bottom and permit container venting. In accordance with one embodiment of the invention, the container top is provided with two gripping tabs with one gripping tab allocated to each of the two compartments. In accordance with another embodiment, the closure devices on the container top and bottom are widened at the comer regions.
