Patent ID: 8534492

Claim:
A sealed storage system, comprising: a container defining a storage volume and having an open top, the open top circumscribed by a peripheral edge region defining a peripheral top surface and a downwardly extending skirt wall region spaced from an upper container wall portion, the skirt wall region having a distal edge; an elastomeric seal member; a lid member configured for attachment to the container to cover the open top in a sealing arrangement, the lid member fabricated as a unitary one-piece structure from a plastic material, the lid member comprising a cover portion and a lid peripheral portion including an annular web portion, and wherein an underside of the lid peripheral portion defines an inner peripheral channel in which the seal member is received, and an outer peripheral channel, the inner peripheral channel and the outer peripheral channel circumscribing the cover portion, and wherein the lid peripheral portion includes an intermediate wall portion separating the inner channel and the outer channel, and an outer wall portion defining an outer wall of the outer channel, the outer wall portion having a bottom edge distal from the annular web portion; the lid member further comprising a plurality of latch portions each coupled to the bottom edge of the outer wall portion of the annular web portion with a connection portion comprising a living hinge portion, each latch portion having a hook portion extending inwardly to latch under the distal edge of said skirt wall region of the container; and wherein the plurality of latch portions are each rotatable about the living hinge portion between an open position and a latching position, the lid member and seal member configured such that, with the lid member disposed on the container and the plurality of latches brought into the latching position, the seal member is brought into compression against the peripheral top surface of the container in a sealed arrangement; wherein the container has a bowl shape, the skirt wall region has a generally cylindrical shape, and the living hinge portion is a linear living hinge portion; wherein the lid peripheral portion includes a protruding transition web region for each latch portion, connecting the living hinge portion to an edge of the lid peripheral region; and wherein each transition web region extends angularly from a living hinge end to the bottom edge of the outer wall portion of the lid peripheral region to allow wider latch portions and enhanced latching force, while supporting the living hinge portions.
