Abstract

1. A multiply gusset valved bag of paper with an inner layer of plastic film or of paper coated with plastic or the like, consisting of a blank, which is closed by folding in of the side parts and by longitudinal center seams to form a tubular member, with lateral gussets and with end plies arranged in relation to each other by overlapping folding or arranged in stages, on one respective side wall and by bonding these plies to head and bottom seams formed with the side walls, with an upper side gusset fold part which is folded inwards together with the adjacent triangular side wall parts at a right angle, such fold part being connected by a triangular side gusset fold member with the side gusset, and a valve flap placed in the inwardly folded side gusset and bonded to the latter, characterized in that the inner edge parts of the valve flap (7), which is coated on at least one side with plastic, are folded over twice and in that the latter are so bonded to the side gusset parts (17 and 18) of the tubular member that the cut edges (26) of the valve flap are tucked inwards and are covered in the interior of the tubular member.
