Abstract

The present invention relates to a container arrangement having a first container wherein the first container is either a container in which a concentrate is located that is configured to form a ready-to-use dialysis solution or a component thereof on a dilution with a solvent, preferably with pure water (water for injection), or an empty container, wherein the container arrangement has a second container in which the first container is received, with the first container having a greater elasticity than the second container and with the first container being configured to expand up to the second container.

First claim

The invention claimed is:

1. A container arrangement having a first container, wherein the first container is either a container in which a concentrate is located that is configured to form a ready-to-use dialysis solution or a component thereof on a dilution with a solvent, or an empty container, and the container arrangement has a second container in which the first container is received, with the first container having a greater elasticity than the second container and with the first container being configured to expand up to the second container, wherein there is a vacuum between the first and second containers.

2. The container arrangement in accordance with claim 1 , wherein the second container is flexible, but not elastic; and/or in that the first bag is flexible and elastic.

3. The container arrangement in accordance with claim 1 , wherein the second container represents a boundary by volume on the expansion of the first container and gives the container arrangement structural strength.

4. The container arrangement in accordance with claim 1 , wherein the first and/or second containers is/are a bag/bags.

5. The container arrangement in accordance with claim 1 , wherein the first and second containers are directly or indirectly connected to one another at one or more points.

6. The container arrangement in accordance with claim 5 , wherein the connection takes place by welding.

7. The container arrangement in accordance with claim 1 , wherein the first and second containers have an upper end and a lower end; and in that the containers are welded to one another at these two ends or at one of these ends.

8. The container arrangement in accordance with claim 1 , wherein the first container is provided with a connector that leads from the interior of the first container to the exterior.

9. The container arrangement in accordance with claim 1 , wherein the second container represents the outer packaging of the first container.

10. The container arrangement in accordance with claim 1 , wherein the first container is a container in which a concentrate is located that is configured to form a ready-to-use dialysis solution or a component thereof on a dilution with a solvent, and the concentrate is present in liquid form.

11. The container arrangement in accordance with claim 1 , wherein the second container is partly or fully folded or rolled around the first container.

12. A container arrangement having a first container, wherein the first container is either a container in which a concentrate is located that is configured to form a ready-to-use dialysis solution or a component thereof on a dilution with a solvent, or an empty container, and the container arrangement has a second container in which the first container is received, with the first container having a greater elasticity than the second container and with the first container being configured to expand up to the second container, wherein the first container is a drainage bag of a peritoneal dialysis system.

13. A container arrangement having a first container, wherein the first container is either a container in which a concentrate is located that is configured to form a ready-to-use dialysis solution or a component thereof on a dilution with a solvent, or an empty container, and the container arrangement has a second container in which the first container is received, with the first container having a greater elasticity than the second container and with the first container being configured to expand up to the second container, wherein the second container has a perforated and/or net-like structure.

14. A method of filling a container arrangement in accordance with claim 1 with liquid or solvent, wherein the liquid or solvent is filled into the first container that expands in this process.

15. The method in accordance with claim 14 , wherein the filling is carried out such that the first container expands up to the second container that represents a structural boundary of the expansion of the first container.

16. A method of utilizing a solution comprising: filling the container arrangement in accordance with claim 1 with liquid or solvent to prepare the solution, wherein the liquid or solvent is filled into the first container that expands in this process; and using the solution as a ready-to-use dialysis solution or as a component thereof.

17. The container arrangement in accordance with claim 1 , wherein the solvent is pure water.
