Abstract
In a rigid hemodialysis salt container of plastic material including a venting valve formed in a container wall with a venting opening extending through the container wall, a seal member covers the venting opening at the inside of the container wall and is connected to the container wall by cementing or welding such that, with the occurrence of a predetermined pressure difference between ambient air pressure and a vacuum generated in the container, the seal member is at least locally ripped off.
