Patent ID: 6921089

Claim:
A gasket sealing system to provide a moisture barrier seal between a lid and a receiving module sized to contain a battery power source therein, the lid having a perimeter surface defined by a perimeter side wall disposed adjacent to a circumferential ledge of the lid perimeter surface sized to be removably positionable relative to an interior surface and an interior wall bounded by a rim of the receiving module, said gasket sealing system comprising: a gasket composed of a resilient material and having a plurality of circumferential surfaces, said gasket being disposed on the circumferential ledge of the lid perimeter surface, said gasket including: a first bonding surface deformable to conform against the circumferential ledge of the lid perimeter surface; a contacting surface disposed in opposed relationship to said first bonding surface, said contacting surface is deformable axially upon engagement with the interior surface bounded by the rim of the receiving module, said contacting surface includes a groove defined therein, whereby said groove provides for deformation of said contacting surface upon engagement against the interior surface bounded by the rim of the receiving module; and an outer lateral surface in opposed relationship with an inner lateral surface of said gasket, said outer and inner lateral surfaces extend between said first bonding surface and contacting surface of said gasket, said inner lateral surface is disposed in adjacent relationship with the lid perimeter side wall, said outer lateral surface being unrestrained in lateral movement by the circumferential ledge of the lid perimeter surface; whereby upon initial engagement of said contacting surface against the interior surface of the receiving module, said outer lateral surface is laterally moved for frictionally engagement against the interior wall of the receiving module thereby providing said moisture barrier seal of the gasket between the lid and the receiving module; whereby upon removal of the lid perimeter surface from engagement with the interior surface bounded by the rim of the receiving module, said contacting surface of said gasket is disengaged from the receiving module without disruption of said gasket.
