This invention relates to a supple bag made by flat assembly of a system of films, intended to constitute, by extension, a stable recipient, and to a process for obtaining said bag. According to the invention, this bag is obtained by assembling the films along lateral and bottom contours and along a base line previously traced geometrically by developing on the films the lateral surface of the recipient which was previously determined in its form and characteristics, in order that the recipient rests, after being filled and closed, in stable manner on its support base, not presenting any point of fold along its lateral edges. The invention finds particular application in the food industry, for packing beverages.

A bag intended to constitute, by extension, a supple recipient, of the type obtained by flat assembly of a system of films constituted by at least one sheet and comprising at least one inner pleat in the form of a flattened V with substantially parallel and rectilinear edges, intended to constitute, after extension, the bottom of the recipient, and intercalated between two portions of sheet with substantially parallel and rectilinear edges, preferably superposed and merged with said edges of the inner pleat, and intended to form the lateral wall of said recipient, said assembly being made along lateral and bottom contours, wherein said bag is obtained by assembling, in addition, the films along a base line, not merged with said parallel and rectilinear edges of the films, defining the contour of the support base of the recipient, said lateral and bottom contours and said base line having been traced geometrically by developing on the films to be assembled the lateral surface of the recipient which was previously determined in its three-dimensional form and characteristics, in order that said recipient rests, after being filled and closed, in stable manner on its support base, not presenting any point of fold along its lateral edges.
