RECYCLABLE BAG

Abstract

A recyclable bag especially large and for large weights with a variable number of handles preferably four at the top, instant discharge by its bottom of all loading material, with a closure that is composed of three layers, the outermost of which has a quadrangular hole with loops that are tied to each other and that supports the other layers of the bottom.

Claims

1. A bag, comprising: a plurality of handles at a top of the bag; an outer closure composed of four flaps formed by a cutting the bag from corner to corner to form an “X” in a bottom of the bag, and forming four triangles in the bottom of the bag and creating a square or quadrangular hole in a center of the bottom of the bag, and edges of the four triangles being sewn together in a direction extending outwardly from a bottom of the bag; a loop or buckle sewn to a central part of an inner edge of each flap, the loops or buckles configured to receive a string that joins the four loops of the four flaps to close the bag; and two or more additional flaps sewn to adjacent or opposite sides of the bag, which unfold to cover the square or quadrangular hole.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The specialized reusable bag for total and instantaneous discharge that is the subject of this request is essentially composed of a composite bottom closure bag, consisting of three flaps or “ears” and an external or lower closure with a strong enclosure system consisting of a tie that goes through a series of reinforced grips.

[0020] The bag can be tubular or formed by a sheet of flexible material (textile or not) with a longitudinal seam.

[0021] A “normal” bag is reinforced the bottom by sticking or sewing a flexible reinforcement, whether textile or not. Then this background is cut in a diagonal cross (from corner to corner), as shown in FIG. 1 extending outward to the three resulting triangles, and then folding inward, and sewn tightly, to an extension of about half of these triangles, depending on the size of the quadrangular hole to be obtained, as shown in FIG. 2.

[0022] FIG. 3 illustrates the reinforced and sewn hole from the inside side.

[0023] In the triangles turned inwards and reinforced, grips are sewn for the enclosure, equally reinforced as the bag, forming loops so that through them the rope that will close the bag passes. The minimum is one loop per side, and there may be more. Also, the cuts that go from the corners of the hole to the outer corners of the bag may or may not be sewn, this being irrelevant to the weight of the bag.

[0024] Subsequently, the loops are tied together, and the bag is thus closed in its external closure, as illustrated in FIG. 4.

[0025] Three of the sides of the bag have sewn from the inside, three ears or flaps, each the size of the bottom of the bag, and that once tied the lower closure, fold on it and one on the other, until forming a closure composed of these three flaps and the lower closure with the loops pierced and joined with a rope of the thickness to the load. This composite closure is not inferior in resistance, being able to be much superior, to a bag without modifications.

[0026] The unloading operation, once the bag hangs over the indicated place, consists simply of cutting the rope of the lower tie, with which everything opens instantly, thus discharging the contents, whatever it is and in any degree of aggregation and/or humidity.

[0027] It should be noted that the lower opening is not a part of the base of the bag, but is the entire base, so it is the maximum to which you can aspire. The flaps instantly unfold down and out once the tie was cut off, and the load, whether sliding or not, whether fluid or not, falls in a fraction of a second.

[0028] The handles of the bag, usually four but which can be more, are sewn to the upper sides of the bag with the corresponding reinforcements.

[0029] The entire bag can be used indefinitely times, occupying when empty and folded a minimum space, which is very useful for storage. It is noteworthy that the only “spare” that must be replaced for re-use is the piece of rope, about 50 cm, of the tie of the lower/outer closure. The opening is performed by an operator with a sharp instrument placed at the end of a long control, proceeding simply to cut the string of the outer/lower closure.

[0030] FIG. 5 illustrates the bag from below and closed, that is, tied the loops of the outer closure and folded the two inner flaps, in order to cover entirely (and in triplicate, including the closure with the tie) the bottom.

[0031] In FIG. 6, left, the piece at the bottom of the bag is shown. FIG. 6 illustrates the four “ears” sewn together from the bottom piece, the “buckles” through which the closing string passes, and the closing string itself. Above this piece folds the Flap 1 and Flap 2, as shown in the figure on the right. The cutting of the string causes a tear of the seams that go to the corners and everything comes out (down) allowing the load to fall.

[0032] To the left of FIG. 7, view of the bags full of cargo and ready to be lifted. On the right, seen from below the loaded bag, with the string joining the four “buckles”, and then the discharge by cutting that string.
