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.

Claims

1. A multi-cell container comprising:

a bag of substantially flat shape made of flexible film;

a partition wall as a separable seal, which welds opposite inner surfaces of the bag and which divides 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, medicines only of powder states being respectively stored in the plurality of compartments, a liquid introduced into said one of the compartments from the inlet-outlet port solving the powdered state medicine, a separation of the separable seal causing the solution to be introduced into the rest of the compartment among the plurality of compartments, so as to solve the powdered state medicine stored therein.

2. A multi-cell container according to claim 1, wherein said partition wall is arranged so that it faces, at least partially, a gusseted bottom of the bag.

3. A multi-cell container according to claim 2, wherein said partition wall comprises a first part extending in a direction along the bottom of the bag from its side to a middle location along the width of the bag and a second part extending in a direction opposite to the bottom of the bag from an end of the first part to the top side of the bag and wherein said one of the compartments, to which said inlet-outlet port is opened, is located on one side of the partition wall adjacent the bottom of the bag while the other compartment with no provision of said inlet-outlet port is located on the side of the partition wall remote from the bottom of the bag.

4. A multi-cell container according to claim 3, wherein said partition further comprises a rounded corner portion at a location where the first and second portions are connected with each other.

5. A multi-cell container according to claim 3, wherein the seal strength of said separable seal is the one, which allows the seal to be separated only by the shaking operation of the bag in the state where the water is introduced into one compartment among said plurality of compartments.

6. A multi-cell container according to claim 3, wherein said separable seal as the partition wall has a value of seal strength in a range between 1 to 5 (N/15 mm).
