Housing for a flexible container

1. An arrangement comprising:

a housing; and

a flexible container,

wherein:

the flexible container is arranged in the housing and filled with a liquid which occurs in a pharmaceutical production process;

the housing is at least partially lined with an elastic foam configured to completely compensate for an increase in volume of the flexible container that occurs upon freezing; and

the housing comprises cover layers made of metal.

2. The arrangement of claim 1 , wherein the elastic foam has decreasing elasticity with decreasing temperature below a freezing point.

3. The arrangement of claim 1 , wherein a hardening of the elastic foam occurs at a temperature between 0 degrees Celsius to −30 degrees Celsius.

4. The arrangement of claim 3 , wherein the hardening is reversible.

5. The arrangement of claim 1 , wherein a hardening of the elastic foam occurs at a temperature between −5 degrees Celsius and −25 degrees Celsius.

6. The arrangement of claim 5 , wherein the hardening is reversible.

7. The arrangement of claim 1 , wherein a hardening of the elastic foam occurs at a temperature between −10 degrees Celsius and −20 degrees Celsius.

8. The arrangement of claim 7 , wherein the hardening is reversible.

9. The arrangement of claim 1 , wherein the flexible container is completely surrounded by the elastic foam.

10. The arrangement of claim 1 , further comprising:

at least one attachment for the flexible container,

wherein the flexible container and the at least one attachment are completely surrounded by the elastic foam.

11. The arrangement of claim 1 , further comprising:

at least one attachment for the flexible container; and

a foam block in the housing for receiving the at least one attachment.

12. The arrangement of claim 1 , wherein the housing is cuboidal.
