A multi-purpose device is disclosed for opening a variety of containers, such as plastic milk jugs, soda cans and soda bottles. A cup-like guide member is received over the tamper-resistance cap of a plastic milk jug and has cleaving lugs projecting downward into the spaces between rupturable connector elements, which join the threaded cap to a fixed locking collar. By twisting the guide member, the cleaving lugs are caused to rupture the connector elements and free the cap for easy removal. A handle provides leverage to facilitate application of the necessary twisting torque. A smaller cup-like section, co-axial with the cup-like guide member but of smaller diameter, is provided with ribbed side walls for engagement with the flutes of a standard twist-off bottle cap to facilitate its removal by twisting. Preferably, the outer end of the handle is provided with a thinned-down portion adapted to be slipped under the lift tab opener of a standard soda can enabling the lift tab to be raised easily by a lifting/prying action of the handle.
