<p>A canister (10) including an elongated hollow plastic body (11) having a wall with inner (13) and outer (12) surfaces, an edge portion (15) on the wall defining an open end, an end (17) on the edge portion (15) extending transversely to the inner (13) and outer (12) surfaces, a porous plastic member (14) having an outer edge portion (19) extending across the open end and fused to the end, an inner portion (20) on the porous plastic member (14) located radially inwardly of the outer edge portion (19) and extending into the body (11) and fused to the inner surface (13) (22) of the wall adjacent the end (17) thereof, and a gas-treating material (23) in the body (11). A method of fabricating the above canister including the steps of applying pressure (33) and vibratory welding energy (34) to the porous member (31) (14) to thereby cause the member (31) (14) which was originally planar in shape to have its outer edge (19) compressed against the end (17) of the body (11) and fused thereto and the central portion (20) inwardly of the outer edge (19) forced into the body (11) and its outer edge (21) fused to the inner surface (13) (22) of the body (11) adjacent the end (17).</p> |
