This invention is directed to a food container comprising a lid and a base. The lid and base form three seals, including a locking seal, to prevent the leakage or spoilage of food during transport or temporary storage. Blades on the lid sealing edge and blades on the base sealing edge strengthen said edges, and further reinforce the seals formed between the lid and base. The lid and base, separately or when assembled, are stably stackable requiring a minimal amount of storage space.

1. A container comprising a lid and a base, wherein said lid has: (a) A substantially planar top portion,(b) A perimeter wall extending downward from said top portion,(c) A rim extending substantially horizontally outward from said wall,(d) A sealing edge comprising: (i) An inner edge extending upward from said lid rim,(ii) A middle edge extending substantially horizontally and outward from said inner edge, and having a protrusion running longitudinally along said middle edge and around said lid,(iii) Blades connecting said inner edge and said middle edge, and(iv) An outer edge extending downward from said middle edge, and having a channel running longitudinally along the inner side of said outer edge and around said lid, and a protrusion immediately below said channel and running around said lid; and said base has:(a) A substantially planar bottom portion,(b) A perimeter wall extending upward from said bottom portion,(c) A lower rim extending substantially horizontally outward from said base wall,(d) An upper wall extending upward from said lower rim,(e) An upper rim extending outward from said upper wall,(f) A sealing edge comprising: (i) An inner edge extending upward from said upper rim,(ii) A middle edge extending substantially horizontally and outward from said base inner edge,(iii) Blades connecting said base inner edge and said base middle edge, and(iv) An outer edge extending downward from said base middle edge and ending with a protrusion;wherein said lid sealing edge and said base sealing edge are molded to be mateable to each other and, upon mating, the channel on said lid outer edge forms a locking seal with the protrusion on said base outer edge, the lid outer edge forms a second seal with the base outer edge, and the protrusion on said lid middle edge forms a third seal with said base middle edge, wherein the engagement of said locking seal urges the engagement of said second and third seal. 2. The container of claim 1, wherein said planar top portion has a semicircular channel close to the edges of said planar top portion. 3. The container of claim 1, wherein said planar top portion has an indent in the middle, wherein said indent optionally has a hole in the middle. 4. The container of claim 1, wherein said planar bottom portion has a semicircular channel around the edges of said planar bottom portion. 5. The container of claim 1, further comprising blades connecting the lower part of the lid perimeter wall with the lid inner edge. 6. The container of claim 1, further comprising blades connecting the base inner edge with the base middle edge. 7. The container of claim 1, wherein more than one said lid may be stacked within one another. 8. The container of claim 1, wherein more than one said base may be stacked within one another. 9. The container of claim 1, wherein more than one said container may be stacked on top of one another.
