The invention relates to a device for gas filling of a duct (7) in a container (1) of a collapsible type, said duct (7) being defined by a first and a second side wall (2) of the container (1), the side walls (2) being joined along a common connecting portion (4) , and said duct (7) comprising an inlet (15) arranged in the first side wall (2) . The device comprises an abutment (21) and a gas module (26) with an outlet (28), which is arranged in a surface of the gas module (26) facing the abutment (21) , and a clamping means (29) arranged outside the outlet (28) , which clamping means (29) is applicable to the abutment (21) for clamping the container (1) , and which outlet (28) , in connection with the clamping of the con¬ tainer (1), is applicable to said inlet (15) for supply of gas to the duct (7) of the container. The device is characterised by a groove (30) formed in said surface of the gas module (26) , which groove surrounds the outlet (28) and is positioned radially inside said clamping means (29) , said groove (30) being arranged to prevent, when supplying gas to the duct (7) intended to be filled with gas, build-up of a pressure above atmospheric on the side, facing the gas module, of said first side wall (2) surrounding said inlet (15) . The invention also relates to a method for filling such a duct with gas . |
