Abstract
A fuel vapor storage canister having a leak-proof screen assembly between a mass of carbon granules in the storage canister and a purge port of the storage canister. The fuel vapor storage canister includes a cup-shaped plastic body, an integral partition which divides the canister body into a pair of relatively deep carbon bed chambers, and a plenum in the canister body at an end of one of the carbon bed chambers which is connected to the purge port and which is covered by the leak-proof screen assembly. The leak-proof screen assembly includes a plastic frame ultrasonically welded to the canister body and a flat fabric screen having a peripheral edge insert molded to the plastic frame.
