  • Patent number: 5983960
    Abstract: The invention is directed to an oil container repository designed to separately collect used motor oil containers and the residual oil left over within each container so that each can be recycled. The invention, in one embodiment, comprises an upper and a lower compartment. The upper compartment has an opening on the top to receive discarded oil containers. A divider separates the upper compartment with the lower compartment. The divider may have a tilted V shape surface and an opening at the bottom. The opening connects the upper compartment to the lower compartment such that the collected containers remain in the upper compartment as they can not fit through the opening. However, opening is sufficiently large to allow the residual motor oil flow through and into the second compartment. The second compartment in turn has an opening for drainage which will permit the drainage of collected motor oil from said second compartment.
