Abstract
Abstract A disposable oil can having displacable tab portions on the top and bottom lids, with a connecting rod lodged between the tabs. According to this arrangement, the oil can can be opened manually by pressing downwardly on the upper tab portion to cause the lower tab portion to open for drainage directly into the crankcase of an automobile without utilizing a pour spout. In an alternate embodiment, the upper pre-scored tab portion opens upwardly, and the lower pre-scored tab portion opens downwardly. A pivot bar is attached to the lower tab portion and is coupled to the upper tab portion so that upward movement of the upper tab causes downward rotation of the lower tab portion.
