Abstract (en)
Starting with a rectangular flat piece that is folded by a transversal fold I-I', making points AA', OO', BB', MM' and NN' coincide and effecting the side sealing seams from AA' to MM' and from BB' to NN', and then according to the method of the invention, vertexes B'' are made to coincide with O, O''' with AA', A'' with B''O and O'' with BB', the portions or flaps O'B'B''O''' and O'A''O'' remaining overlying. Then the seam of the edges O''BB' to OB''A'' and OB''A'' to A'AO''' is made, forming a bottom with a square shape in which those two portions or flaps remain overlying. That bottom can incorporate a relief valve housed in holes provided in the two flaps that form the former. <IMAGE>
