A method for manufacturing a flexible container including a body, a base including an emptying spout and a cover including a filling spout, includes: cutting, from a sheet of flexible material, four main panels of the body and the base and four cover panels, each main panel having a square or rectangular shape having four sides, the bottom side being extended by an approximately trapezoidal extension, whose end towards the bottom is extended by a tab, the extension and tab forming the base and emptying spout, each cover panel having a substantially trapezoidal shape with a base towards the bottom and whose end towards the top is extended by a tongue forming the filling spout; forming a fold in each main panel along the top side; fixing the fold to form at least one loop per main panel; assembling and securing together the four main panels and four cover panels. |

1. A method for manufacturing a large-capacity flexible container including a body with, downwards, a bottom comprising an emptying spout, and upwards, a cover, the cover including a filling spout,
characterized in that it consists in:
cutting out from a sheet of flexible material, on the one hand, four main panels (1), and on the other hand, four cover panels (2), the main panels being intended to form the body and the bottom and the emptying spout of the container, the cover panels being intended to close the top of the container while forming the filling spout (11), each of the main panels having in part a square or rectangular shape (3) with four sides, i.e. two lateral sides (7), one upper side (8) and one lower side, a shape whose lower side is continued by a substantially trapezoidal extension (4) whose downward apex is continued by a tab (5), the extension and the tab being intended to form the bottom and the emptying spout of the container, each of the cover panels having in part a substantially trapezoidal shape (9) with a downward base and whose upward apex is continued by a tongue (10), the tongue being intended to form the filling spout extended upwards,
forming a fold (6) in each of the main panels along the upper side, opposite to the side of the extension,fixing said fold to form at least one loop per main panel,assembling and fastening to each other the four main panels and the four cover panels, the folds being arranged on the outside of the container, the base of each cover panel being assembled to the upper side of the corresponding main panel, the main panels being assembled two-by-two at least along their lateral sides and their corresponding extensions, the lateral sides in correspondence of the cover panels being assembled two-by-two to each other, the upper ends of the tongues being left free so as to form an upper opening of filling spout, substantially square in shape. |
