US Patent 7434697 Disposable, spin-on filter

A disposable, spin-on fluid filter is constructed and arranged to mount onto a base that is configured with a threaded mounting shaft. The base provides a fluid inlet flow to the filter and a fluid exit path from the filter. The filter construction includes a housing canister having a closed end and an opposite, open end and a fluid filtering media positioned within the housing canister. A mounting post is formed as part of the closed first end of the housing canister. The mounting post is constructed and arranged for assembly to the threaded mounting shaft of the base. The design focuses on the elimination of any nutplate and on repositioning the location where the fluid filter is connected to the head to the closed end of the canister.
