Abstract
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. The box also has perforated cutouts to allow viewing of the liquid and its color and to provide access to the ports of the inner bladder stored in the box. A color indicator may be added to the liquid for indicating its usability.

Claim 1
Independent Claim
443 words
A system adapted to store and deliver a liquid, which comprises: (1) a first unit comprising: (a) a first box having a lid and a bottom section, said first box being closed when said lid is mated with said bottom section; (b) first handle means for keeping said lid mated with said bottom section; (c) a first inner bladder disposed in said first box and having an enclosed volume for storing the liquid; (d) first dispensing means comprising at least first and second dispensing ports, connected to said first inner bladder for dispensing the liquid in said enclosed volume; and (e) first gas barrier means for enclosing said first inner bladder and said first dispensing means for substantially reducing the flow of CO 2 or O 2 from the environment to the liquid in said enclosed volume; (2) a second unit comprising: (a) a second box having a lid and a bottom section, said second box being closed when said lid is mated with said bottom section; (b) second handle means for keeping said lid mated with said bottom section; (c) a second inner bladder disposed in said second box and having an enclosed volume for storing the liquid; (d) second dispensing means comprising at least first and second dispensing ports, connected to said second inner bladder for dispensing the liquid in said enclosed volume; and (e) second gas barrier means for enclosing said second inner bladder and said second dispensing means for substantially reducing the flow of CO 2 or O 2 from the environment to the liquid in said enclosed volume; (3) a third unit comprising: (a) a third box having a lid and a bottom section, said third box being closed when said lid is mated with said bottom section; (b) third handle means for keeping said lid mated with said bottom section; (c) a third inner bladder disposed in said third box and having an enclosed volume for storing the liquid; (d) third dispensing means comprising at least first and second dispensing ports, connected to said third inner bladder for dispensing the liquid in said enclosed volume; and (e) third gas barrier means for enclosing said third inner bladder and said third dispensing means for substantially reducing the flow of CO 2 or O 2 from the environment to the liquid in said enclosed volume; and (4) interconnection means for fluid interconnection of said first, second, and third dispensing means, in which said second port of said first unit is connected to said first port of said second unit, and in which said second port of said second unit is connected to said first port of said third unit.
