Abstract:

An annular drip collector is shaped and dimensioned to slidably sleeve onto the cylindrical wall of an oil filled filter cartridge, in need of replacement, while the cartridge is projecting from an engine and attached by its threaded open end. The large diameter wall of the collector forms a truncated conical trough with the adjacent cylindrical portion of the cartridge wall proximate its open end to collect oil spillage. The integral, smaller diameter cylindrical wall, or skirt, of the collector toward the closed end of the cartridge is substantially equal in inside diameter to the outside diameter of the cartridge. At least one integral, inward projecting, annular rib, tooth or flange in the lower cylindrical wall, seals the collector against the cartridge by reason of the flexible, resilient, polyethylene plastic of the collector. The outwardly flared, truncated conical, collector will nest with other collectors for shipment. An annular cap snap fits over the large diameter opening of the collector to retain oil spillage when the cartridge is horizontal, the caps also nesting for shipment.
