  • Patent number: 4599758
    Abstract: In a first embodiment, a pair of cylindrical rods are held in closely spaced parallel relationship by support members mounted in the ends of the rods. The rods have confronting surfaces throughout their length. Pairs of overlapping cutting blades are mounted in the rods and between the confronting surfaces. A container is opened by being inserted between the confronting surfaces and drawn against the blades. When opened, the end of the container opposite the opening is then inserted between the rods and drawn between the confronting surfaces to empty the contents by pressing the opposite sides of the container together. In a second embodiment a flanged slot formed in a flat holder provides the confronting surfaces for emptying the container. Cutting blades mounted in the handle in way of the slot are used to cut the container open.
