Abstract:
Packaging box made of cardboard for the transport of a load, said box comprisinga lateral enclosure formed from at least four vertical walls and from a horizontal bottom integrally fixed to said enclosure via joining lines,a heat-shrinkable plastic material intended for packaging the load and for keeping the load in place,at least one attached board inserted between at least two first opposite vertical walls, in such a way that the transverse edges are in contact, via the heat-shrinkable plastic material, with at least part of the joining lines of said first walls,and means for blocking the at least one board against the bottom,wherein the at least one board presses the heat-shrinkable plastic material onto the inner face of the bottom of the box, at the same time allowing curtain portions of free material to escape on either side of two mutually confronting transverse opposite edges of the at least one board, said curtain portions extending from said transverse edges over a length sufficient to cover one another with the heat shrinkage of the plastic material, and in that, in order at least partially to form blocking means, the lower face of the at least one board is at least partially directly adhesively bonded to the upper face of the bottom of the box, through at least one recess of the film or on a surface devoid of heat-shrinkable plastic material.
