ABSTRACT:
A device which may be conveniently utilized to collect oil drained from an engine crankcase includes a fluid impermeable plastic bag and a rigid drain stand. The drain stand is designed to hold the bag below the oil drain in a manner facilitating flow of oil into the bag while simultaneously preventing larger objects, such as the drain plug, from also falling into the bag. This drain stand is further preferably constructed of a single sheet of corrugated fiberboard material which may be shipped or sold in a flattened or collapsed configuration, and then unfolded and assembled with the bag by the end user. A unique locking mechanism is provided for joining portions of the corrugated fiberboard sheet without adhesives to form a strong, rigid structure. After the oil has been completely drained into the bag, the bag can be removed from the drain stand, sealed, and then disposed of in an ecologically sound and safe manner.
