Abstract (en)
[origin: FR2776990A1] The invention concerns a bag (1) comprising an envelope (2) closed on one side by a base (3), and defining a hole (4) on the other side, containing a load (5) capable of passing, for example by gravity, through said hole, when said bag is turned upside down, said envelope (2) being so shaped on itself at said hole to close said bag. The invention is characterised in that, on the side opposite to the base (3), the envelope (2) has a shape, in particular a folding line, successively obtainable by: folding outwards, then folding inwards, the bag opening (4) edges (2a), to form a tucked up flap (2b) extended by an outer envelope (2c); folding the flap (2b) parallel edges (2d) brought closer, to form at least one fold (7) closing the bag internally; folding the outer envelope (2c) parallel edges (2e) brought closer, to form at least one fold (9) for closing the bag internally. The invention also concerns a bag (1) as per claim 1, characterised in that the bag (1) internal closure fold (7) and/or the bag (1) external closure fold (9) are welded, bonded or pressed.
