Abstract: The present invention relates to a tray made of corrugated cardboard sheet material, and to blanks for preparing such a tray having a polygonal cross-section. Said blank comprises sidewalls, raised edges or portions of raised edges on two opposite sides of an upper portion, and a lower wall forming the bottom (36) of the case. Each raised edge or portion of raised edge includes at least one rounded portion (34), and the bottom includes perforated surface portions (35) which have a shape complementary to that of the rounded portions, which are arranged opposite the latter, and are arranged so as to fit into the rounded portions of the tray from below.

Abstract: The present invention relates to a box (30, 31) and a blank (1) made of corrugated cardboard sheet material having a polygonal cross section, including side walls (3, 4, 5, 6), 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 (26) in the upper wall, and the bottom comprises portions (18) 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.

Abstract: The invention relates to a set of blanks for making a packaging box (1), to such a box and to a method for making such a box. The set includes a first blank comprising at least four main flaps connected together by first folding lines for forming the walls of the base (3) of the box, and a second blank including three panels connected together by third folding lines and including flips connected to the panels by a fourth folding line for forming the lid (2) of said box. A tearable flap (30) is connected to a flap by a perforated junction line (31), two flaps and two non-adjacent trapezoidal panels for forming the side walls and the base of the lid, wherein the two blanks are arranged so as to enable a sufficient covering in order to glue the same onto each other at the opposite inner and outer edges of the flaps and trapezoidal panels when the perforated folding line and the fourth folding lines are aligned or substantially aligned.

Abstract: The invention pertains to a carton, a blank and a process for manufacturing a carton of sheet material. The carton includes a cover formed by inner and outer flaps, and two sinkable corner regions situated respectively on either side of the carton or of the cover, straddling the fold lines corresponding to two walls and two opposing flaps. It includes an elongate handle comprising a lower band made of a sheet material formed at least in part by a detachable part belonging to at least one outer flap and a reinforcing upper band secured to the lower band having ends fixed on each side to opposing lateral walls, underneath the sinkable corner regions with respect to the upper face of the cover. The handle encompasses or extends opposite the sinkable corner regions so that, when the handle is pulled substantially perpendicularly to the upper face of the cover, handle portions situated opposite the sinkable corner regions sink into the regions.

Abstract: An automatic page turning device of the type comprising a movable element controlled by a motor of which the operation is controlled by a control member to be actuated by the user. It is characterized in that it comprises a suction tube to lift a page as well as a movable element comprised of a double acting pusher. The double acting pusher is situated directly above a document and is movably mounted in linear translation in the two opposite directions transverse to the side of the pages of a document and along which they are bound together. The suction tube and the double acting pusher are also movably mounted perpendicularly to the plane of a support structure.
