A container for liquid contents, comprising a compartment 4 which is defined by flexible walls 2, 3 and whose volume is dependent on the relative position of the walls 2, 3. The walls 2, 3 have rim portions which engage each other and along which the walls 2, 3 are joined with each other in a common connecting portion 6. The container is characterised in that the walls 2, 3 are made in one piece, which is folded to form said walls 2, 3, and that the walls 2, 3 along said rim portions are sealed to form said connecting portion 6. The present invention also concerns a method and a device for producing such a container. |
