A container for liquid or pulverulent contents has flexible walls (12, 14) which are interconnected to form a closed compartment, the volume of which is dependent on the position of the walls (12, 14). Two opposing side walls (12) are joined along a common connecting portion and the container has a duct means (16), which has a uniform composition of materials along its entire length, between the two side walls (12). The duct means (16) extends from the compartment to the outside of the container (10) and is sealed when the container is in an empty state before filling. The invention also concerns a method and a device for making the container as well as a method and a device for filling the container. |
