Abstract

A perfected cardboard box with automatic closure, characterized by the fact that whether its cover is attached, forms part or results from a single piece with one of the side faces of the box, turning by a fold, as a hinge, around one of the sides of its mouth, as if it is loose or is separable from it, present its flat upper face, equal to the straight section of the box, that is, equal to the mouth of this, to which they will remain rigidly joined by the corresponding dihedrals, the skirts or front faces and the lateral ones that are necessary, which overlap, when closing the box, on the upper parts of the lateral faces of the box. And essentially at the bottom of one or more of the flaps of the lid, one or more strips of cardboard will be glued together. The box, on the other hand, has attached to the upper edge of one or more of its corresponding walls, several tabs, depending on the case, capable of rotating around these edges whose natural and elastic tendency will be upwards, thereby closing the lid and overlapping on these flanges the walls of this, will be occluded, between the upper edges of the strips and the top face of the lid, retaining it and preventing the opening of the box at all, as long as this lid does not tear or tear .
