Container assembly with flexible seal
A storage container assembly comprises, a storage receptacle, a removable lid, and a seal. The storage receptacle has a base and a continuous sidewall connected to the base. The sidewall has an interior surface and an exterior surface. The lid has a main body that covers at least a portion of the storage receptacle. The lid has a first and a second receiving channel. The seal has a securing member and a blade portion. The securing member goes into the first receiving channel of the lid to connect the seal to the lid. The blade portion of the seal contacts the interior surface of the sidewall. The exterior surface of the sidewall contacts the second receiving channel. The sidewall of the storage receptacle is within the second receiving channel. The blade portion forms a generally fluid tight seal with the sidewall while the sidewall contacts the second receiving channel.
1. A storage container 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, the sidewall having an interior surface and an exterior surface;
a removable lid having a main body configured to cover the peripheral edge of the storage receptacle, an annular first receiving channel defined by first and second channel walls, the first and second channel walls extending downward from a bottom surface of the removable lid, and a second receiving channel;
a seal having an annular securing member and an annular blade portion, the annular securing member being at least partially disposed in the first annular receiving channel of the lid for connecting the seal to the lid, the annular blade portion of the seal extending from the annular securing member and into the second receiving channel for contacting the interior surface of an upwardly projecting extent of the sidewall when the lid is connected to the storage receptacle; and
wherein when the lid is connected to the storage receptacle, an upwardly projecting extent of the sidewall of the storage receptacle projects upwardly into the second receiving channel and the exterior surface of the upwardly projecting extent of the sidewall of the storage receptacle contacts an interior surface of the second receiving channel of the lid such that the upwardly projecting extent of the sidewall is located within the second receiving channel, and the blade portion of the seal forms a seal with the interior surface of the upwardly projecting extent of the sidewall when the sidewall is in contact with the second receiving channel.
2. The storage container assembly of claim 1 , wherein the blade portion of the seal additionally comprises at least one rib, the rib adapted to contact the interior surface of the sidewall.
3. The storage container of claim 1 , wherein the blade portion of the seal forms an angle of less than forty-five degrees (45°) from vertical while the blade portion contacts the interior surface of the sidewall.
4. The storage container assembly of claim 3 , wherein the blade portion of the seal forms an angle of from ten degrees (10°) to forty-five degrees (45°) from vertical while the blade portion contacts the interior surface of the sidewall.
5. The storage container assembly of claim 1 , wherein the securing member of the seal comprises a plurality of ribs configured to create a press fit within the first receiving channel of the lid.
6. The storage container assembly of claim 1 , further comprising a vent disposed in the removable lid.
7. The storage container assembly of claim 1 , further comprising a viewing window disposed in the removable lid and configured to provide visual confirmation that a seal has been formed between the lid and the storage receptacle.
8. A method of forming a container assembly, the method comprising:
providing a storage receptacle having a base and a sidewall, the sidewall projecting upward from the base and terminating at a peripheral edge, the sidewall having an interior surface and an exterior surface;
providing a removable lid having a flexible seal, the removable lid having an annular first receiving channel defined by first and second channel walls, the first and second channel walls extending downward from a bottom surface of the removable lid, and a second receiving channel, the flexible seal having an annular securing member and an annular blade portion, the annular securing member of the flexible seal being at least partially disposed in the annular first receiving channel of the lid for connecting the seal to the lid, the annular blade portion of the seal extending from the securing member toward an exterior wall of the second receiving channel;
aligning the removable lid with the storage receptacle, such that the second receiving channel is proximate to the peripheral edge of the sidewall of the storage receptacle; and
securing the lid to the storage receptacle and causing an upwardly projecting extent of the sidewall of the storage receptacle to project upwardly into the second receiving channel and for the sidewall of the storage receptacle to deflect the blade portion of the seal into the second receiving channel, and further causing an interior surface of an upwardly projecting extent of the sidewall of the storage receptacle to contact the blade portion of the seal and an exterior surface of an upwardly projecting extent of the sidewall of the storage receptacle to contact an interior surface of the exterior wall of the second receiving channel.
9. The method of claim 8 , wherein when the sidewall deflects the blade portion of the seal, the blade portion is deflected vertically.
10. The storage container assembly of claim 1 , wherein the annual first receiving channel, annular securing member and the annular blade are each configured as one of a circular shape, a rectangular shape and an oval shape.
11. The method of claim 8 , wherein the annual first receiving channel, annular securing member and the annular blade are each configured as one of a circular shape, a rectangular shape and an oval shape.
