  • Patent number: 10226400
    Abstract: A multi-cell container includes a bag of substantially flat shape made of flexible film, a partition wall as a separable seal welding opposite inner surfaces of the bag and dividing an inner space of the bag into a plurality of compartments and an inlet-outlet port located at a periphery of the bag so as to be opened to one of the plurality of compartments for introduction and/or discharge of liquid. The partition wall has a horizontal section extending in a direction along the bottom of the bag and a vertical section bent therefrom and extending to the topside of the bag. A first larger volume compartment is formed on one side of the partition wall adjacent the bag bottom and a second smaller volume compartment is formed on the other side of the partition wall. The inlet-outlet port is opened to the first chamber.
