A container of a collapsible type for liquid or pulverulent contents, comprising a compartment (3) which is defined by flexible walls and whose volume depends on the relative position of the walls, said walls comprising two opposite side walls (2) with edge portions (4) which engage each other and along which the side walls (2) are joined in a common connecting portion (5). The compartment (3) is sealed in the empty state of the container before filling. The container is characterised by a duct-defining portion (6), which is arranged inside said connecting portion and along which said side walls (2) are joined with each other. The duct-defining portion (6) comprises two mutually separated weld joints (11) which define a duct (7) extended between the side walls (2), which at a first end communicates with said compartment (3) and at a second end connects to and is sealed by a duct-sealing part (10) of said connecting portion (5). The present invention also concerns a method for manufacturing such a container. |
