Definitions

• the present invention relates to a corrugated carton for transporting a load, comprising an open box having four vertical walls and a horizontal bottom, a cover comprising flaps glued to the upper periphery of the box and a wedging plate in cardboard for maintaining the load.
• It also relates to an apparatus for manufacturing such a box.
• Packaging crates are already known for the transport of objects of different shape and random including the frame of the mail order.
• the present invention aims to overcome these disadvantages and finds a particularly important application although not exclusive in the field of mail order and more particularly of devices and / or objects for medical use.
• the present invention therefore proposes a crate and a packaging device that responds better than those previously known to the requirements of the practice, in particular by enabling the load to be locked effectively by means of a shim which is not glued but which adapts to all forms of products to stall in the box ensuring a perfect fit.
• the wedge which is used being made of corrugated cardboard is a clean, non-polluting, recyclable, non-messy material which, depending on the type of product, may be heavy, light, strong, of different constitution or shape, in terms of both its thickness and its number of flutes (double flute, thin flute, etc).
• the calibration operation can be performed automatically, which allows to minimize costs considerably, the material of the wedge (corrugated cardboard) being more cheaper than that used in most other technologies such as those mentioned above (addition of blocking material or shimming by shrink film for example) .
• the present invention essentially proposes a corrugated cardboard box for transporting a load of a height corresponding to a first determined dimension h, said box comprising an open box having four vertical walls of height equal to a second one. determined dimension h c > h and a horizontal bottom and a cover comprising flaps arranged to be glued to the upper periphery of the box, characterized in that it comprises a cardboard wedge plate for holding said load in place, the wedging plate comprising a central panel of dimension slightly smaller than the horizontal section of the box, in that said central panel comprises two opposite first flaps respectively connected to two corresponding peripheral edges by marking grooves, said first flaps being of height H greater than a third dimension determined h c -h (H> h c - h) and at least two opposite second tab flaps respectively connected to the two other peripheral edges of said panel by marking grooves, so that when said wedging plate is pressed into the box, for to be in contact with said load, the first and second flaps cooperate frictionally with the
• the invention makes it possible to obtain a packaging package with a load in a box as described above, in which the first flaps are arranged to have a height greater than the height of the walls when the panel of the plate is plated on the load previously introduced into the box, and in that said clamping plate is pressed into the box, to be in contact on one side with said load, and on the other side blocked in force by the face internal lid.
• Each first flap is constituted by a rectangular flap of height greater than 2/3 of the height of the box; each first flap is greater than or equal to 1/3 of the width of the box;
• the box comprises two second tab-shaped flaps per side;
• the marking grooves are only folding initiation lines, retaining a high resilience elasticity.
• the marking grooves are simply pre-folds, making it possible to help the carton to bend in this place in case of force exerted on the latter, contrary to the fold lines themselves, deeper;
• the thickness of the corrugated cardboard is of the order of 3mm.
• the invention also proposes an apparatus for the manufacture of a box as described above, characterized in that it comprises means for feeding the plate to a box previously formed and loaded, means for introducing the force of the plate in the box and internal plating of the first flaps on the inner face of the wall of the corresponding box at the upper periphery of the box, means for folding the ends of the first flaps inwards by force of the box horizontally at said upper periphery, sizing means and plating means for bonding the lid to the opening of the box thus blocking the load between the plate and the bottom of the box.
• the plate is forcefully inserted into the box, the first flaps are pressed onto the inner face of the wall of the box at the upper periphery of the box,
• the ends of the first flaps are folded towards the inside of the box horizontally at the level of the said upper periphery, -
• the edges of the lid are glued and the latter is pressed against the upper edges of the box by crushing the end of the flaps, which causes the blocking of the load between the plate and the bottom of the box.
• Figure 1 is a plan view of a wedging plate used according to a first embodiment of the invention.
• Figure 2 is a plan view of a second embodiment of a wedging plate usable according to the invention.
• Figure 3 shows a partially exploded view, a box according to the embodiment of the invention more particularly described.
• Figure 4 is a sectional view of a box according to one embodiment of the invention.
• FIG. 1 shows a wedging plate 1 according to a first embodiment of the invention, made of corrugated cardboard, of thickness for example 3 mm.
• the central panel 2 which comprises two first rectangular flaps 3, connected to the respective peripheral edges 4 and 5 opposite of the central panel 2 by marking grooves 6.
• the first flaps 3 have a height H arranged to be greater than a predetermined height
• Ho being for example equal to 1/3, 1/2 or
• the central panel 2 further comprises on each of its other two opposite edges 7 and 8, two second flaps 9 identical, rectangular, small dimensions forming tab.

• the first flaps are of the order of 160 mm high and 150 mm wide, the small flaps being for their part regularly distributed on both sides on the peripheral edge 7 and 8, opposite, being away from the edge by 50 mm while having a width of 20 mm and a height of 80 mm.
• Figure 2 shows another embodiment of a wedging plate 10 according to the invention.
• the plate 10 comprises a central panel 2, first flaps 3 as described with reference to the However, it comprises only two lateral tongues 11 on these two opposite sides 7 and 8, said tabs extending over most of the periphery, for example eight-tenths or six-tenths of the length of the corresponding peripheral edges 7 and 8.
• FIG. 4 shows in particular in section a packaging box 12 made of corrugated cardboard for transporting a load 13, said box comprising an open box 14 comprising four vertical walls (see FIG. 3) 15, 16, 17 and 18 and a horizontal background 19.
• the box 12 further comprises a cover 20 known per se comprising a rectangular cover panel 21 and four side flaps 22 connected to said cover panels 21 by fold lines 23.
• the box 12 further comprises the plate 1 for wedging as described with reference to Figure 1 and whose panel is of a size slightly smaller than the horizontal section of the box, for example 1 to 2 mm on each side.
• the wedge plate 1 is depressed in force
• the plate 1 may and / or will otherwise twist increasing said friction forces in some places allowing improved blocking.
• the free end edges 25 and 26 of the first flaps 3 are also folded in force between two points of support represented by the arrows 27 inside the box and 28 outside the box to be placed substantially horizontally in the right upper peripheral edges 29.

• This plate is fed by means known per se (for example flip-flop) 36 from a magazine 37 and is disposed substantially above the opening 38 of the box 14.
• the wedging plate is lowered with force introduction means 39 comprising a jack chuck 40 and control means (not shown) of the position of the upper part of the load 13 so as to avoid crushing the products.
• the mandrel comprises for example four independently controlled cylinders with adjustable pressure, knowing that the distance between strokes cylinders can be several centimeters, to allow the plate to marry the load. Given the marking grooves of the first flaps and second flaps they will pre-bend to come scrub along the inner walls of the box.
