  • Patent number: 5065758
    Abstract: A cold pack for treating an injury of a subject person. A cooling media, e.g. of BLUE ICE is encased in elongate plastic closed end cylinders. The cylinders are inserted in parallel pockets formed in a wrapper, e.g. made of cloth with the interconnecting cloth material forming flexible hinges between the cylinders. Straps provided on the wrap enable the application of the pre-chilled cold pack to be applied to the injured area of the subject person. The container and plastic partially insulate the cooling media which has the doubly beneficial effect of reducing the cooling effect and extending the life of the cold pack.
