A triple sealed container, comprising a base portion and a lid portion. The base consisting of a unitary component including a bottom portion attached to an upwardly extending perimeter wall, which is flurther connected to a peripherally extending rim having an inner and outer edge. The lid also consists of a unitary component, with a downwardly extending wall, which is connected to a peripherally extending rim also having an inner and outer edge. The base edge and the lid edge are correspondingly shaped to be mateable. The lid rim is also correspondingly shaped to engage the base rim. The contact of the edges and the rims form three main seals. The first seal is a result of the contact between the exterior edges of the base edge and the lid edge. The second seal is a result of contact between the interior edges of the base edge and the lid edge. The first and second seals are shaped to provide a self-reinforcing seal configuration wherein the initial engagement of the first or second seals initiates the third seal. The third seal is a result of the peripherally extending base and lid rims contacting each other leaving a seal surface area greater than the areas of said first or second seals. This third seal provides substantially more protection against spoilage and spilling, by dramatically decreasing the odds of foreign substances contacting food products, or food products leaking into contact with surfaces exterior to the container. In addition, the assembly is stackable and same size nestable.
