ABSTRACT:
A fluid filter (10) of the spin-on automotive type has a housing with a unitary closure member (18). The unitary, or one-piece, closure member (18) includes provision for mounting of the filter and for fluid flow therethrough. Two opposed annular flanges (78, 80) of the closure member receive between them the marginal edge (72) of the filter shell in a fluid-tight crimped engagement. This arrangement facilitates manufacture of the filter by providing support to the shell wall (68) during the crimping operation and also provides an exceptionally strong joint between the shell (12) and closure member (18). Another embodiment of the filter has a closure member (18) with a marginal edge (76) having a portion of reduced thickness which facilitates its crimped engagement with the filter shell (12). Methods of making such closure members attain a unitary closure member without welding operations.
