Claims
- 1. A container having three seals, comprising:
- a base having
- a substantially planar bottom,
- a base perimeter wall extending substantially vertically upward from said bottom,
- a base rim extending substantially horizontally outward from said base perimeter wall, and
- a base sealing edge attached to said base rim; and
- a lid having
- a substantially planar top,
- a lid perimeter wall extending substantially vertically downward from said top,
- a lid rim extending substantially horizontally outward from said lid perimeter wall,
- a lid sealing edge an ached to said lid rim, and
- a locking lip protruding from said sealing edge;
- wherein said base sealing edge and said lid scaling edge are molded to be correspondingly mateable to each other and upon mating said base scaling edge and said lid sealing edge form a middle seal and an exterior seal and said base rim and said lid rim form an interior seal, wherein said interior seal has a surface area greater than said middle seal and said exterior seal, said base sealing edge further comprising an inner base edge extending generally vertically upward from said base rim; a middle base sealing edge extending substantially horizontally outward from said inner base edge; and an exterior base sealing edge extending substantially vertically downward from said middle base sealing edge; and said lid sealing edge further comprising an inner lid edge extending generally vertically upward from said lid rim; a middle lid sealing edge extending substantially horizontally outward from said inner lid edge; and an exterior lid sealing edge extending substantially vertically downward from said middle lid sealing edge, said locking lip protruding from said downward exterior lid sealing edge; wherein upon mating of said base and said lid, said base rim and said lid rim form said interior seal and said middle base sealing edge and said middle lid sealing edge form said middle seal and said exterior base sealing edge and said exterior lid sealing edge form said exterior seal.
- 2. A container according to claim 1, wherein at least a second base is stackable within said base.
- 3. A container according to claim 1, wherein at least a second lid is stackable within said lid.
- 4. A container according to claim 1, wherein the engagement of one of said exterior seal, said middle seal or said interior seal urges the engagement of the other two remaining seals.
- 5. A container having three seals, comprising:
- a base having
- a substantially planar bottom,
- a base perimeter wall extending substantially vertically upward from said bottom,
- a base rim extending substantially horizontally from said base perimeter wall, and
- a base sealing edge having
- an inner base edge extending generally vertically from said base rim,
- a middle base sealing edge extending substantially horizontally from said inner base edge, and
- an exterior base scaling edge extending substantially vertically from said middle base sealing edge;
- a lid having
- a substantially planar top,
- a lid perimeter wall extending substantially vertically downward from said top,
- a lid rim extending substantially horizontally from said lid perimeter wall, and
- a lid sealing edge having
- an inner lid edge extending generally vertically from said lid rim,
- a middle lid sealing edge extending substantially horizontally from said inner lid edge, and
- an exterior lid scaling edge extending substantially vertically from said middle lid sealing edge, and
- a locking lip protruding from said exterior lid scaling edge;
- wherein, said base sealing edge and said lid sealing edge are molded to be correspondingly mateable to each other and upon mating of said bottom and said lid, said base rim and said lid rim form an interior seal, said middle base sealing edge and said middle lid sealing edge form a middle seal and said exterior base sealing edge and said exterior lip sealing edge form an exterior seal, and
- wherein, the engagement of one of said exterior seal, said middle seal or said interior seal urges the engagement of the other two remaining seals, and said interior seal has a surface area greater than said middle seal and said exterior seal.
