<p>The bottom of the container is formed from a pair of square flaps (4, 5) which extend the two walls (19, 20) of the container downwards over half of the lower edge of these walls, these flaps, which were initially opposite, being joined, each by means of its free lower edge (D, B), to the half (A, C) which has no extension of the lower edge of the opposite wall of the container, this container thus being provided with a flat and square double bottom formed by the two crossed over flaps, and the two lines joining the flaps to the walls of the bag being located on the sides of the resulting double bottom, one on an edge of the inner bottom and the other on an edge of the outer bottom, these two joining lines having an end located at the same angle from the square bottom. Application to containers intended for 100 kg to several tons of bulk materials, the bottom of the container being robust and strong and, in particular, to containers with lifting loops and a filling slot (3). <IMAGE></p> |
