Abstract: The present invention relates to material packaging made of corrugated cardboard sheet having a polygonal cross section, comprising lateral walls, a lower plane forming the bottom of the packaging, and an opposite upper plane. It comprises at least one portion (25, 26) projecting with respect to the upper plane. The bottom (30) comprises at least one surface portion (15, 16) that is cut out over a portion of the thickness of the cardboard sheet, is compressed and in the form of a non-through hollow, referred to as a hollow portion, the shape of which matches the projecting portion, in line with the latter and arranged to fit together with the projecting portion of the packaging below.

Abstract: The invention relates to a cardboard tray made of three parts, to an assembly of blanks, and to a device and method for producing such a tray. The tray comprises a first part defining a bottom connected by first fold lines to two first opposite sidewalls and two second parts defining second opposite sidewalls, each comprising at least one longitudinal first flap connected to said second wall by a second fold line and glued on the bottom, and two sets of transverse flaps, each comprising at least one transverse flap glued to a first corresponding opposite side wall, respectively.

Abstract: This is a packing case (40), a set of cutouts and a method of obtaining a case comprising a bottom that forms a half-case (41) obtained from a first cutout and a lid formed from a second cutout, the underside of the bottom being equipped with recesses (19, 85, 108, 109, 110, 111) and the lid comprising at least two tabs (33, 43, 54, 55, 56, 57, 73, 74, 75, 88) bonded onto its top face, in vertical alignment with the recesses of complementary shape. The lid comprises a central panel (20, 37) equipped on its sides with four lateral panels (21, 22, 23, 24, 77, 79, 81) of which two (21, 23) are equipped with end flaps (27, 28, 29, 30) said tabs each being connected to one of said end flaps.
