  • Patent number: 9056757
    Abstract: A combination bottle opener by which to remove a cap from the top of a bottle and can opener by which to remove a lid from the top of a can. The opener includes a body having a curved head located at one end thereof to surround the bottle cap to be removed and a pair of tapered legs located at the opposite end to fit below the lid to be removed from the can. A force-transmitting plate is affixed to the top of the body so as to extend between the pair of legs. A force applied to the force-transmitting plate of the opener in a first direction causes an edge of the plate to rotate into engagement with the bottle cap to lift the cap off the bottle. A force applied to the force-transmitting plate in an opposite direction causes the tapered legs to rotate into engagement with the lid to pry the lid off the can.

  • Patent number: 5361502
    Abstract: A drum deheader device comprising a pair of mounting bars for respectively supporting a shearing blade and an opposing anvil adapted to be positioned at opposite sides of a can cover portion of a chime and a linkage interconnecting said bars to advance and retract the bars for cutting and releasing the device, the linkage being formed and arranged to cut the chime twice as the operating levers are moved back and forth toward and away from each other, the blade being positioned to cut through an upper section of an outer layer only of the chime and to expose an inner layer of the chime beneath the shear blade which has a wedge face which slides on the exposed portions of the inner layer of the chime to separate the layers apart, thereby loosening a cover from the container and forming a continuous strip of scrap material whereby sliver forming is inhibited.
