  • Patent number: 4869398
    Abstract: A liquid container is packaged in a box having a removable handle which also acts as a closure device for the opening and closing of the box. The liquid may be bulk sterile fluids, chromatography buffers, industrial enzymes packaged in glycerol, liquid nutrient solutions, and similar liquids. The container comprises an inner bladder made of polyvinyl chloride. The inner bladder is wrapped in a carbon dioxide/oxygen gas barrier. This gas barrier may be in the form of a plastic bag. The gas barrier reduces or prevents the deterioration of the liquid in the inner bladder. The inner bladder has three ports for accessing the liquid. These ports are of a septum-type which can indicate tapering, The inner bladder also has a fill tube for use in filling, and a metal hook for hanging if the inner bladder, is removed from the box. The box is designed to support weight sufficient to allow stacking of several boxes with associated filled inner bladders.
