In a container (1) of flexible material and including 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 provi
In a container (1) of flexible material and including 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 floded end area to predominatly the same length as the depth (19) of the guesset (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 parallel 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 botton (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 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.

A container, especially a bag, of flexible material, such as paper, plastic film, foil or similar materials comprising a tube-shaped blank of said material divided by means of gussets into two opposite side walls and two intermediate pairs of gusset walls, and having at least one bottom of the block bottom type including a folded end area of said side walls and said pairs of gusset walls, wherein said container (1) including a tightly sealed, outwardly folding discharge valve (11) in one of the said block bottoms (8, 9), said valve being resealable and provided with a gripping means (16), and its opening being provided by means of shortening at least a part of the folded end areas of one pair of gusset walls (6) and adjacent side walls (5) to substantially the same length as the depth (19) of the gusset (2, 3).
