Abstract
A packaging box, cutouts, method and device for producing corrugated cardboard boxes comprising walls, a base (6) and a cover (7), the inner face of the base being provided with at least two recesses (33) and the cover comprising at least two tabs (38) adhered to the upper face thereof, directly above the recesses of complementary shape.

Claims10
A method for producing a packaging box from at least one cutout of corrugated sheet board material or corrugated board, characterized in that the at least one cutout comprises a series of main flaps and adjacent tabs capable of forming a rectangular bottom and a top, the lower face of the bottom being provided with at least two recesses, and the top comprising at least two tongues capable of being adhesively bonded onto its upper face, in line with the recesses of complementary shape, and in that the recesses and/or the tongues are entirely located inside the corresponding face or faces;
- and
- characterized in that after unstacking the cutout or cutouts from a vertical magazine, the cutouts are moved horizontally in order to bring them finally into the position for shaping the box, and during the travel the tongues with adhesive previously applied are automatically turned over and pressed against the corresponding upper face of the main flap in question in order to adhesively bond them thereon.
A device for producing a box of corrugated sheet board material from a cutout or a set of cutouts, the cutout or the set of cutouts comprising a series of main flaps and adjacent tabs capable of forming a rectangular bottom and a top, the lower face of the bottom being provided with at least two recesses, and the top comprising at least two tongues capable of being adhesively bonded onto its upper face, in line with the recesses of complementary shape, said box being arranged in order to be mounted automatically on a shaping station, characterized in that, the recesses and/or the tongues being entirely located inside the corresponding face or faces, the device comprises means for advancing the cutouts flat, one by one, from a stack of cutouts,
- means for applying adhesive onto the tongues and/or the opposing surface on the upper face of the box,
- and means for folding the tongues through 180° in order to apply them onto said surface of the upper face during the transfer to the shaping station.
