CA 2159583
A bag or pouch made from a pair of flat walls formed by flexible sheet material, such as plastic films. The walls are sealingly interconnected so as todefine between the opposite walls a storage chamber (20) for containing a fluid. A fluid discharge passage (17) communicates with the storage chamber (2) at a junction position (21 ) and is arranged outside the storage chamber, and the bag or pouch is such that the opposite wall parts defining the discharge passage are moved into mutual sealing contact at at least one sealing position when fluid has been filled into the storage chamber. In order to improve the self-sealing effect of the bag, the storage chamber (20) extends beyond the junction position (21 ) in a direction towards an outlet end (22) of the discharge passage (17). This means that the angle a is an acute angle. Alternatively or additionally, at least one restriction may be defined in the discharge passage (17), preferably at or closely adjacent to the sealing position.
