The invention relates to a method for manufacturing a large-capacity flexible container comprising a body, a base comprising an emptying spout and a cover comprising a filling spout, said method consisting in cutting, from a sheet of flexible material, four main panels (1) of the body and the base and four cover panels (2), each of the main panels having in part a square or rectangular shape (3) having four sides, the bottom side being extended by an approximately trapezoidal extension (4), the end of which towards the bottom is extended by a tab (5), the extension and the tab being intended to form the base and the emptying spout of the container, each of the cover panels having in part a substantially trapezoidal shape (9) with a base towards the bottom and the end of which towards the top is extended by a tongue (10), the tongue being intended to form the filling spout, in forming a fold (6) in each of the main panels along the top side, in fixing said fold in order to form at least one loop per main panel, in assembling and securing together the four main panels and the four cover panels, the folds being disposed on the outside of the container, the base of each cover panel being joined to the top side of the corresponding main panel, the main panels being joined together along their lateral sides and their corresponding extensions, the corresponding lateral sides of the cover panels being joined together, the top ends of the tongues being left free in order to form an upper opening of the filling spout which is substantially square. |
