A packaging box, cutouts, method and device for producing corrugated cardboard boxes comprising walls, a base () and a cover (), the inner face of the base being provided with at least two recesses () and the cover comprising at least two tabs () adhered to the upper face thereof, directly above the recesses of complementary shape. The recesses and/or the tabs are situated fully inside the corresponding face or faces ().

Packaging boxes with centring tab, cutouts and set of cutouts, method and device for producing such boxes

A method for the production of a packing case from a one-piece blank, comprising a band of at least four main panels connected together by parallel fold lines, and furnished with two series of flaps situated on either side, for respectively forming at least partly the bottom and the top of the case. The band comprises a precut transverse line over the main panels to divide the blank into a first and a second half-blank. The half-blanks are separated, the first is placed in a transfer channel, the second is held in a plane higher than that of the transfer channel, the first is transferred to a mandrel while applying adhesive, and the first is wrapped around the mandrel. The transfer channel allows the second to be lowered to the channel, transferred to the mandrel, and wrapped around the first half-blank before folding the flaps.

Packaging boxes with centering tab, cutouts and set of cutouts, method and device for producing such boxes

The present invention relates to a box () and a blank () made of corrugated cardboard sheet material having a polygonal cross section, including side walls (), an upper wall forming the top of the box and a lower wall forming the bottom of the box. The top of the box comprises at least one cut-out convex portion () in the upper wall, and the bottom comprises portions () which have a perforated surface having a complementary shape to the said convex portions, situated directly above the latter and arranged so as to be fitted into the convex portions of the box below.

Box having convex centring elements, and blank for manufacturing such a box

The present invention relates to a one-piece blank () made of corrugated cardboard for the production of a display case (), the case, the method and the machine for producing said case. The blank comprises a band () of panels () connected together in pairs by parallel fold lines (). The band () comprises a precut transverse line () making it possible to divide the blank into two half-blanks (), said transverse line determining on either side and for each parallel fold line () two separate portions of fold line () offset relative to one another in order to make it possible to at least partly compensate for the thicknesses of cardboard when the second half-blank is wrapped over the first half-blank around a mandrel.
