Abstract: To solve problems in a conventional electric can opening apparatus wherein it is impractical to drain the unwanted liquid from the inside of the can after opening the container and disposing of the top lid or top without touching it. The composite can opener includes a body with a gripping member gripping a can while an opening member cuts the top of the can open and a piston that selectively pushes the top into and out of the can after it has been cut.

Abstract: A relatively flat and entirely portable can lid removing device comprising can end retaining structure which permits relative rotation of the can and the lid removing device, a can lid cutter which cuts the lid from the remainder of the can during the mentioned relative rotation and creates no sharp edges or burrs in the process, so that the remainder of the can may be used as a container, e.g. a drinking can.

Abstract: An opener for removing an end panel portion of a container end unit. The opener includes a simple housing which may be molded of plastics material and which carries a blade for penetrating and severing the end panel along a preformed weakening line in the form of a score. There is also a magnet for retaining the severed end panel portion relative to the opener. Further, the housing has a separate skirt portion which is radially movable and which carries a ridge for underlying a double seam securing an end unit to a container body so as to lock the opener on the end unit once the blade has penetrated the end panel.
