Abstract A container and a method as well as an assembly for its manufacture In a container (1) of flexible material and in- cluding a tube-shaped blank divided into two opposite side walls (5) and two intermediate pairs of gusset walls (6) by means of gussets (2, 3), and having at least one block bottom (8, 9), a tightly sealed, outwardly folding discharge valve (11) is provided in the block bottom (8), said discharge valve being resealable and provided with a gripping means (16). The opening of the valve is formed by shortening a part of the folded end area to predominantly the same length as the depth (19) of the gusset (2). When manufacturing the container (1) from tubing, it is gusseted and divided into blanks corresponding to the container. Then a part of the end area of the blank is cut along a first intersection para- llel and adjacent to the middle fold (7) in one of the gussets (2) when the blank is folded up, and along a second, transverse intersection (23) one gusset depth (19) apart from the fold lines (25) around which the final folding of the side walls is performed, whereupon the block bottom (8) is folded, while optionally mutually glueing or welding the folded side walls. Only the parts of the block bottom (8) not in touch with the gusset walls (6) with the cutout are optionally glued or welded. The resulting container with block bottom has a well functioning resealable discharge valve and is suitable for manufacture in a continuous process from an endless material without use of extra material.
