Abstract

A SYSTEM FOR CLOSING AND OPENING SACKS AND BAGS, which is characterized in that it comprises a sheet of appropriate material, rectangular in shape, which through the slits arranged in the longitudinal direction is folded at its ends towards its interior, forming even accommodations for strips of equal length to that of the sheets, so that said strips are located between the folded previously made in the mouth of the bag as well as the longitudinal end planes of the sheet, and these two elements are scrambled by the zigzag of the folding of the sheet. mouth of the bag, press the longitudinal edges of the strips and the sheets inside the angles formed by the different folds of the bag and sheet, constituting the fixing means for retaining the mouth of the bag, preventing its deployment or looseness by sliding, being ensured the permanence of this assembly by rivets, eyelets or staples that join the ends of the planes of the folded sheet and the ends of the interleaved strips and in such form its closure or closure is achieved that for its opening and emptying of the contents it has to be torn at least one of these ends through the climbs located on the sides of the sheet and those of the strips that facilitate the total segregation of its extremity so that, when said end is released, it can be displaced by dragging towards the opposite end the sheet and strips assembly until its total separation from the mouth of the bag, or by the tearing the two ends, so that once the remaining parts of the sheet and the strips are removed, it can be traced to its emptying, since the simple pressure of the contents when leaving is sufficient to unfold the parts that could have been folded in the mouth of the sack.
