Abstract

A container includes a dry concentrate designed such that the dry concentrate forms an acid liquid concentrate, or a part of an acid liquid concentrate, which is suitable for manufacturing a dialysis solution, on the dissolution of the dry concentrate in a liquid, preferably in water.

First claim

What is claimed is:

1. A container comprising:
at least one dry concentrate, the dry concentrate being provided so that the dry concentrate forms at least one acid liquid concentrate or a part of an acid liquid concentrate which is suitable for manufacturing at least one dialysis solution on a dissolving thereof in a liquid;
at least one connector with which the container is coupleable to a dialyzer or to a preparation unit for the acid liquid concentrate;
a first film and a second film which form walls of the container, with one of the first film and the second film having a folded section in an empty state of the container which forms one of the walls of the container in a filled state of the container, with the folded section being formed by two limbs which are arranged acutely to one another, and which have a different length from one another, and with the folded section connecting the first film and the second film which form the walls of the container; and
wall regions which face toward one another in at least one region and between which a trough-shaped region or a recess is formed, with the dry concentrate being at least also present in the trough-shaped region or in the recess in an operating position of the container,
with the two opposite walls of the container being the first film and the second film, and the base being the folded section, so that an asymmetrical triangle results when the container is filled or unfolded.

2. The container in accordance with claim 1 , wherein the folded section is configured as a separate part or is connected in one piece to one of the first film and the second film.

3. The container in accordance with claim 1 , wherein the container is configured as a stand-up container.

4. The container in accordance with claim 3 , wherein the stand-up container has a stand-up section arranged at a top thereof during use of the container.

5. The container in accordance with claim 1 , wherein the first film and the second film and the folded section, or a corner region thereof, have a same material of construction.

6. The container in accordance with claim 1 , wherein a thickness of the first film and the second film is 200 micrometres and a dimensioning of the first film and the second film is such that the filled container occupies a volume of 5 liters.

7. The container according to claim 1 , wherein the acid liquid concentrate is associated with a dialysis solution for hemodialysis.

8. The container according to claim 1 , wherein the liquid is water.
