Abstract
A fluid filter of the disposable automotive spin-on type has a cup-shaped member and a closure member which together form a chamber for receiving a filtering media. The cup-shaped member has a relatively thin side wall and an open end defined by a marginal edge including a bead. The closure member is a one-piece stamping of uniform thickness and substantially thicker than the cup-shaped member. The closure member closes the open end of the cup-shaped member and includes an annular rim which extends perpendicularly to the plane of the closure member and generally parallel to the side wall of the cup-shaped member. A channel defined by the rim receives the bead of the cup-shaped member and the rim is crimped to form a fluid-tight connection between the members.
