  • Patent number: 5961021
    Abstract: An ampule separator which can efficiently cut off ampules from a strip of series-connected plastic ampules. A strip of series-connected plastic ampule is put in a stocker having an outlet at its bottom, with the individual ampules arranged horizontally. A pair of horizontally arranged rotors are provided under the outlet of the stocker. Each rotor is formed, in its outer peripheral surface, with a groove in which the body of a plastic ampule can be partially received. As the rotors are rotated, the lowermost one of the plastic ampules is received in the grooves. As the rotors are rotated further, the ampule in the grooves is pushed down and cut off along a cutoff line formed between this and the immediately upper ampules by the rear edges of the grooves, with the upper ampules supported on cylindrical outer surfaces of the rotors.

  • Patent number: 5947360
    Abstract: A cutting blade for cutting sheet materials such as plastic film or metal foil is provided. The cutting blade incorporates a row of cutting teeth (50) projecting from a flat surface between the surface's folded edges. The depth of cut of the cutting blade is limited by the height that the cutting teeth project from the flat surface. In addition, by spacing the cutting teeth sufficiently closely together, the cutting teeth provide a bearing surface sufficient to support human skin so that the cutting blade cuts plastic film and metal foil but does not easily puncture human skin.
