Container assembly with flexible lid seal and releasing arrangement
A storage container assembly comprises a storage receptacle and a removable lid. The storage receptacle has a base and a continuous sidewall connected to the base. The sidewall projects upward from the base to a peripheral edge. The removable lid has a rigid central cover portion and a flexible seal portion that traverses a perimeter of the rigid central portion. The flexible seal portion has a release tab disposed along its periphery, and a pocket disposed inward of the release tab. The flexible seal portion further has a ledge disposed generally at the periphery of the flexible seal portion. The ledge contacts the peripheral edge of the storage receptacle. The flexible seal portion further has and a blade portion disposed below the ledge. The blade portion contacts the side wall of the storage receptacle and forms a generally fluid-tight seal with the sidewall.

securing the removable lid to the storage receptacle such that the ledge of the flexible seal portion contacts a top of the sidewall of the storage receptacle, the pocket is located inward of the sidewall, and the blade portion of the flexible seal contacting and being displaced by the sidewall of the storage receptacle to affix the lid to the storage receptacle.
11. The method of claim 10 , wherein when the sidewall displaces the blade portion of the seal the blade portion is moved to a generally vertical orientation.
12. The method of claim 10 further comprising deflecting the release tab to allow air to escape from the storage receptacle to move the ledge of the flexible seal into contact with the top of the sidewall.
13. A removable lid with a generally fluid tight seal for use with a storage receptacle, the lid comprising:
a rigid cover portion having an outer edge defining a perimeter; and
a flexible seal portion traversing the perimeter of the rigid central cover portion, the flexible seal portion having a release tab disposed along a periphery of the flexible seal portion and a pocket disposed inward of the release tab, the flexible seal portion further having a ledge disposed generally at the periphery of the flexible seal portion, the flexible seal portion further having a blade portion disposed below the ledge and extending away from the rigid cover portion, the blade portion being moveable from a first generally horizontal orientation to a second generally vertical orientation when the lid is engaged with the storage receptacle.
14. The removable lid of claim 13 , wherein the flexible seal portion has a top portion and a lower portion, the top portion having a first generally vertical sidewall and the ledge, the lower portion having a second generally vertical sidewall and the blade portion.
15. The removable lid of claim 14 , wherein the second generally vertical sidewall is recessed a distance from the first generally vertical sidewall.
16. The removable lid of claim 15 , wherein the distance the second generally vertical sidewall is recessed from the first generally vertical sidewall is approximately the same as a thickness of the blade portion.
17. The removable lid of claim 13 , wherein the top portion additionally has a score line formed in a top surface of the flexible seal portion and disposed above the pocket.
18. The removable lid of claim 13 , wherein the flexible seal portion has a groove, the groove traversing a perimeter of the rigid cover portion.
19. The removable lid of claim 13 , wherein the rigid cover portion is transparent glass.
20. The removable lid of claim 13 , wherein the flexible seal portion comprises silicone.
21. A storage container assembly having a generally fluid tight seal, the assembly comprising:
a storage receptacle having a base and a sidewall connected to the base, the sidewall projecting upward from the base and terminating at a peripheral edge; and
a removable lid having a rigid central cover portion having an outer edge defining a perimeter of the rigid central cover portion and a flexible seal portion extending along the perimeter of the rigid central cover portion, the flexible seal portion having a release tab disposed along at least a portion of a periphery of the flexible seal portion and a pocket disposed inward of the release tab, the flexible seal portion further having a ledge disposed generally at the periphery of the flexible seal portion, the ledge contacting the peripheral edge of the storage receptacle, the flexible seal portion further having a blade portion disposed below the ledge, the blade portion contacting the sidewall of the storage receptacle and forming a generally fluid-tight seal with the sidewall, wherein the flexible seal portion has a top portion and a lower portion, wherein the top portion includes a first generally vertical sidewall, the ledge, and a score line, the score line disposed on a top surface of the flexible seal portion and disposed above the pocket, and wherein the lower portion includes a second generally vertical sidewall and the blade portion.
