发明名称 Piercing filter oil containment boot
摘要 Spillable oil from an oil filter and adjacent engine cavities of trapped engine oil is transferred outwardly through filter housing sidewalls at designated low points to a temporary boot container by gravity following a piercing operation through the filter housing. Oil transfer to the container is performed prior to breaking the seal between the engine block and the filter. All of the spillable oil is caught in the boot containment device which incorporates internal tack like hollow piercing elements. The required piercing force to drive the tacks into the filter wall may be applied to the exterior of the filter boot using common filter strap wrenches, or by light taps from a hammer, wrench or similar tool.
