Abstract
A disposable oil filter containment sheath is provided for use during oil changes for combustion engines. The sheath has a closed bottom, a cylindrical sidewall, and an open top. The resilient sheath is rolled to an initial collapsed position for placement on the bottom of an oil filter mounted on the engine, and it is partially unrolled along the filter. The filter can then be loosened to allow oil to drain into the sheath for capturing a reservoir. After the filter is removed from the engine, the sheath is completely unrolled and tied at the top so as to fully enclose and contain the oil filter and oil. The sheath and its contents are then ready for disposal.
Claims4
A system for removing a used oil filter without spilling oil comprising in combination:
- a cylindrical oil filter;
- and
- a stretchable rolled containment sheath having a sidewall including generally longitudinally extending internal channels which allow used oil to drain towards a reservoir in a bottom of the sheath;
- wherein the containment sheath is enclosingly unrolled about the cylindrical oil filter beyond a length of the cylindrical oil filter such that the containment sheath will capture any oil leaking or dripping from the oil filter as the oil filter is removed from an engine, said internal channels permitting flow of any leaking or dripping oil along the length of the cylindrical oil filter to said reservoir when said containment sheath is unrolled about said cylindrical oil filter.
