Abstract: The present invention is a container assembly for food and liquids. The container assembly has a lid and a base each of which has a series of prongs. The prongs of the base and lid interlock to form a continuous seal with high surface area and passages with many bends that together prevent air and bacteria from entering the container assembly and prevent food and liquids from leaking out of the container assembly. One or more of the lid prongs has a protrusion that fit into corresponding depressions between the base prongs to urge the rims together and create and maintain the seal. In a second embodiment, the outermost prong of the lid also has a protrusion attached to it which locks around the outermost base prong further urging the rims together and further creating and maintaining the seal.
