  • Patent number: 6402798
    Abstract: An air filter housing (12) includes twist and lock structure (42) having a first position (FIGS. 5, 7, 10) permitting axial movement (66) of a cover (34) and base (36) relative to each other, and being rotatable in a first rotational direction (44) from the first position to a second position (FIGS. 4, 6, 9, 12), and in the second position preventing axial movement of the base and cover relative to each other, and being rotatable in a second opposite rotational direction (64) from the second position to the first position. Anti-rotation lock structure (70, 110, 140) provides a rotational retention force holding the twist and lock structure in the second position. The anti-rotation lock structure includes an arm (74, 112, 142) flexibly bendable about a bend line extending parallel to the axis (14) of the housing.
