Definitions

the present invention relates to a packaging shim. It also relates to packaging using such a shim and a packaging process which exploits all the possibilities of such material. It finds application in any field of packaging in cases or in packaging in heat-shrinkable plastic film.
Another conventional function of such shims is to absorb, within a certain range of energy values, the shocks that the package can undergo at the risk of the packaged product.
the present invention relates to a packing block, intended to come between a package and a product to be packaged, produced by cutting an elongated strip of a thick sheet material with damping characteristics. data, which is then shaped so as to surround at least partially in a cutting plane the product to be conditioned, constituting first portions remote from the product which come into contact with the interior of the packaging and second portions which connect the first portions therebetween, said wedge being remarkable in that at least one of the first portions is produced in the form of a box composed of a bottom and two sides, the box being completed in the direction of the width of the strip constituting the wedge, by two forms intended to come to bear on the side walls of the packaging.
the present invention also relates to a packaging using such a wedge.
the present invention also relates to a method of packaging at least one product in a container such as packaging on a packaging station, characterized in that it consists: - to extract from a reserve, a desired length of shim according to the invention, - to form hinges intended to perfectly adapt the wedge around the product to be packaged, - to arrange the hold relative to the product and the packaging, - then deposit the hold and product assembly through an opening in the packaging, - close the packaging.
Figure 1 there is shown a sectional view of a packaged package using a wedge according to the invention.
the product to be packaged 2 is seen in section. It is here in parallelepiped shape, but can have more complex shapes.
the product 2 is removed from the packaging 1 by the wedge 3.
a polyurethane is chosen.
a plastic material is chosen having characteristics of elastic flexibility.
Such a material can be shaped so as to form folding hinges and hollows by stamping with a heating press.
these various treatments are carried out on the packaging site, on request by an automated device which is controlled by the characteristics of the product which arrives at the packaging station.
the four corners of the product are housed in recesses 4, 5, 6, 7 connected to each other others by flat parts 8, 9, 10, 11.
the recesses constitute in the wedge first portions which make it possible to separate the product from its packaging and the flat faces, second connecting portions. They are box-shaped, each consisting of a bottom and two sides, each side serving to connect the bottom to the rest of the hold.
connection portions play a preponderant role in the distribution of the forces transmitted from an angle of the packaging to one of the recesses 4 to 7.
FIG 2 there is shown in two views one of the boxes of the wedge intended to separate the product from its packaging.
the material intended to constitute the wedge is in the form of an elongated strip from which a determined length can be extracted.
the only area is shown which allows a recess like 4 to be made.
a hollow zone made up of a first parallelepipedic part 12 is made by hot stamping, to which two other parallelepipedic hollows of smaller surface 13, 14 are connected.
the recess 12 is intended to separate the product from its packaging on the faces visible in the plane of FIG. 1 and the two recesses 13 and 14 make it possible to separate the product from the two other faces of the packaging which are parallel to the plane of Figure 1 and therefore not shown in this figure.
the two recesses 13, 14 are extended by shapes of triangular section 15, 16.
grooves 19, 20 are stamped on each side of the first portion 12-18 which allow the second portions 21, 22 to rise 45 ° above the plane of FIG. 2 to press on the product walls as shown in Figure 1.
the shim is initially stored in a continuous form, for example on sheets wound on reels.
the reel is placed near the packaging station.
a quantity of shim corresponding to the need for wedging is extracted from the reel. Then the hold is formed by stamping the desired number of hinges and boxes and possibly lateral shapes. Their relative positions are also configurable depending on the product and its packaging or container.
the wedge is interposed between the product to be packaged and the opening of the container or packaging.
the product is then directed by gravity or by an automatic transfer machine into the container, the wedge being driven naturally inside the container which comes to interpose and place itself properly between the internal walls of the container and the external walls of the product.
this arrangement is not specific to the invention. In other applications, it is possible to use an automaton and an introduction of the hold / product assembly into its container in another plane, the opening of the container being suitably arranged.
FIG 3 there are shown two views -a- and -b- of a solution to the problem of drilling the cardboard box by the sharp angles of the wedge.
Each corner consists of two boxes 23 and 24 connected to each other by a bottom 25 which has two grooves 26 and 27 which allow it to be folded.
a single groove is made on the connection bottom between the two boxes. It suffices to fold the wedge at the point of the sharp corner of the product.
the shims of the invention can be stored before packaging in a reserve where they hold a minimal volume.
the conventional distance between a fragile product and its packaging is on average 5 cm.
the wedge is, before its forming, in the form of a sheet typically 5 millimeters thick, we see the gain in volume that the invention generates.
FIG 4 there is shown another variant of a shim according to the invention which has the double advantage of distributing the wedging forces over the entire container on the one hand, and of being adaptable to a large extent to all dimensions of products to be packaged.
the wedge 30 is constituted by a succession of boxes 31, 32, 33 like that shown in Figure 2, optionally separated from each other by grooves or not.
a box is constituted by a bottom 34 which comes to bear on the container and a portion 35 which comes to bear on a part of product to be packaged.
the boxes are of trapezoidal section so as to allow their stacking.
a reserve of shims according to the invention may comprise, in a reduced volume, a large length of shim.
FIG. 6 shows two bands 40 and 41 during stacking.
Each strip is made up as we have seen by a succession of boxes connected to each other by flat sections. It is noted that this arrangement of the boxes in trapezoidal section has the advantage of stacking several strips of shims.
a reserve of shims according to the invention it is known to extract a strip in the standby position, and take by extraction from reel a useful length of shim.
FIG. 5 there is shown a product 37 installed in a container constituted by a cardboard box 38.
the wedge 39 is constituted by a succession of boxes of identical sizes.
the width to length ratio of the product is 4/5.
the corners of the product receive the place of the hold where there is a hinge.
the hinges are three in number: 40, 41 and 42. They are produced as above by stamping grooves over the entire width of the wedge in the dimension perpendicular to the plane of the section of FIG. 5. They can be executed with the request on the packing station.
the packaging operation is reduced. It suffices to extract a sufficient length of hold from a reserve. Then, depending on the product to be packaged, three hinges are placed. The product is brought above the opening of the box, the wedge being interposed between the two. Then, the hold and product assembly is arranged by gravity or any other means of transfer in the box.
the wedge must be positioned relative to the body and the product so as to surround the product in the desired manner.
This method finds application in packaging chains on which only products whose length to width ratio is an integer multiple of the pitch p of the pattern of the block.
a certain adaptation is possible by shifting by a quantity x the position of the hinge from the standard position shown in the drawing.
FIG 7 there is shown a product assembly 50 / wedge 51 and packaging 52 in a step of the packaging method according to the invention.
a suitable shim length was extracted from the reserve not shown in the drawing. Then, on a forming station, we have, as a function of the parameters defining the geometry and the fragility of the product 50, stamped boxes 53 at positions compatible with these parameters as well as three hinges 54.
the product 50, the shim 51 and a plastic film 52 were brought successively above the opening 66 of a shaper 55. It is noted that the walls 65 and 68 of the shaper 55 are arranged so as to allow correct insertion of the product 50 / shim 51 / packaging 52 assembly.
the assembly is then lowered according to the vertical arrows in the drawing.
the plastic film is applied to the undersides of the boxes 53.
the parts 56 and 61 of the shim 51 come into contact with the frustoconical parts of the shaper, which has the effect to bring them closer to the corresponding faces 57 and 62 of the product 50.
the plastic film is applied to the block.
the parts 56 and 61 are applied to the product 50, the face 60 of which rests on the central part 59 of the wedge.
the product assembly 50 / block 51 / packaging 52 rests on the bottom 67 of the chamber 69 of the shaper 55.
the free straight part of the plastic film 52 is folded over the chamber 66, which also has the effect of folding the right-most part 63 of the shim 51 onto the upper face 64 of the product 50.
the free ends 58a and 58b of the wedge 51 are connected together by means known to those skilled in the art.
the plastic film 52 is welded and shrunk by heating the assembly. Then the packaged product is extracted from the conformator.
