Abstract: A device configured to be disposed within a granular medium to raise a layer thereof, the device having: a flexible envelope forming an internal volume; an inflatable element in the internal volume, interposed between the envelope's upper and lower surfaces, the element's inflation and deflation varying the internal volume; an injection device for filling the inflatable element with a fluid; the device being switchable from a first configuration having the inflated inflatable element occupy a first volume to a second configuration having the inflated inflatable element occupy a second volume greater than the first to deform the upper surface vertically to raise the granular medium's layer, and vice versa; the device further being switchable from the first or second configuration to a third configuration having the envelope's lower surface deform vertically to allow the device to ascend through the granular medium. Also, a method of deforming a granular medium layer.

Abstract: A box and a blank or a set of blanks made from corrugated cardboard sheet comprising side walls, a top wall linked to at least two of said opposing side walls by a junction line or a folded edge, and a bottom wall forming the bottom of the box. The top wall comprises at least two convex portions comprising a projecting part, and the bottom comprises at least two perforated surface portions of complementary shape arranged to engage with the projecting parts of the box below. Each convex portion comprises an oblique triangular or substantially triangular panel belonging partly to a side wall or a folded edge.

Abstract: The present invention relates to a box, a blank, a set of blanks made from corrugated cardboard sheet and a method for forming a box having a polygonal section. The box has at least one centring tab (7) straddling at least one folding line (4) on its upper wall (2), cut out on its lateral sides (8), connected on one side to the upper wall (2) by a first joining line (10) and on the other side to the adjacent side wall (5) by a second joining line (6), a parallel and offset intermediate folding line (14) being provided such that the tab (7) forms a projecting portion (16) on account of the folding. The bottom comprises at least one perforated surface portion (18) which has a shape complementary to that of the tab such that the lateral edges of the recess are designed to cooperate in contact with the lateral edges of said tab, and is designed to fit into the projecting portion of a box from below.

Abstract: A tray made from cardboard sheet material comprising a rectangular base and a ring of side walls, including two opposed first side walls symmetric with respect to a transverse axes of the tray and two second walls, including a second rear wall and a second front wall of lesser height than the other walls.

Abstract: The invention concerns a generally parallelepiped corrugated box for packaging and transporting objects, the box comprising a lid formed by a lateral can-band carton including a front wall, a rear wall, and side walls and a top, and a tray forming a base including a central panel comprising four main sides each respectively provided with a first flap. The front and rear flaps are U-shaped and define each with the top a central recess enabling an object in the box to be gripped manually by a user from the side and/or from above. One or several partly precut portions and/or one or several bonding points enable the walls of the lid to be detached from the first flaps of the tray by manual separation resulting from a force applied perpendicularly to the walls.
