    Abstract: A device for recovering oil from a plurality of open mouthed containers comprising a funnel having a plurality of openings at its upper end and an outlet port at its lower end. The outlet port is threaded to receive a collection container, such as a plastic oil container. The upper end of the funnel has a plurality of spaced openings, each opening has associated with it a ring having a plurality of vertical ribs spaced around the interior circumference for releasably retaining the neck of a container by a pressure fit. Each ring has a removable cap removably attachable to it for covering an opening not in use, thereby preventing dirt from entering the funnel. A set of braces having a mounting plate extends from the funnel for securing the device to a wall. An optional valve permits closure of the outlet port when a recovery container is removed, thereby preventing fluid from leaking out of the device.
