Definitions

  • the subject of the invention is a packaging sheet by laminating consisting of a support made of porous or perforated cardboard for small objects and intended to receive a film glued by suction, conforming to the shape of these objects.
  • plates of this kind are used in the packaging technique by laminating, which consists of depositing on the plate resting on a loading table the objects to be packaged, then transferring the plate onto the lower plate of a packaging machine.
  • laminating which has an upper plate supporting a transparent film.
  • the film adheres to the plate by enveloping the objects thanks to a suction practiced under the lower plate, suction which is exerted on the film since the support constituting the plate is permeable to the air.
  • a last operation consists in separating these elementary plates by cutting.
  • the plates lack rigidity. Whether they are breathable by their very nature or through perforations, they are necessarily thin and therefore warp easily, which can cause problems for their storage, seizure and transport. Moreover, such warping is particularly harmful at the loading stage, since objects, even if they are relatively stable, tend to move by sliding, as well as at the final stage of packaging itself, because, if the plate n 'does not adhere properly to the lower plate of the machine, the vacuum created below it will suck air laterally and no longer through it.
  • the finished product loses its aesthetics and regularity. If they move a little more, the finished product should be discarded.
  • the object can be in the path of the cutting blade during separation into elementary plates; the object itself and the blade can then be damaged.
  • Another solution consists in housing the objects beforehand in a container, but in this way a double packaging is finally practiced, first in the container, then on the plate, and the cost price of the container is increased.
  • the object of the present invention is to make available to packers a plate free from the above-mentioned drawbacks without any noticeable increase in its cost price and for this purpose it relates to a packaging plate which is characterized in that the cardboard support is provided with a sheet of a material also permeable to air, on which the above-mentioned objects are arranged, said sheet being shaped to have non-aligned asperities and glued to the cardboard support by those of these asperities which are in contact with him.
  • the material constituting the sheet is paper.
  • the plate has thus acquired a completely satisfactory rigidity. Much more the unstable objects which one deposits there are wedged by the asperities of the sheet in all directions, since these asperities are not aligned. The objects therefore remain in place, even if the plate is transported without great care from the loading table to the machine table. This also overcomes the major drawback arising from this mobility of objects when the plate is made up of several elementary plates that have to be cut.
  • the sheet is bi-wavy.
  • the sheet leaves certain parts of the support free. This arrangement makes it possible to print the parts of the support left free, which do not participate directly in the conditioning of the object, and which in general are drilled for hanging.
  • the conditioning plate constitutes a set of elementary plates arranged in rows and in columns
  • the sheet can advantageously be in the form of strips, each of which covers the same area of the elementary plates of a line.
  • This economical and rational arrangement makes it possible to have elementary packaging plates, part of which, generally the upper part, is reserved for hanging and printing.
  • the plate rests on a counter-plate of larger dimensions, itself permeable to air.
  • the use of the plate according to the invention is limited to the areas directly interested in the packaging, the others remaining free for printing, decoration or attachment perforations.
  • the conditioning plate 1, represented in FIG. 1, is essentially constituted, as best seen in FIG. 2, by a rectangular cardboard support 2 which is breathable, on which a sheet of paper 3 has been pasted. biondulate.
  • biondulé designates a sheet of paper which has received parallel corrugations, which are here the corrugations which we see in section in FIG. 2, the generatrices of these corrugations not being rectilinear, but in turn corrugated as shown in Figure 1.
  • the bonding of this biondulate sheet of paper 3 on the cardboard support 2 is done according to its lower generatrices by lines of glue such as 4, deposited on the paper by perfectly conventional gluing machines .
  • biondulated paper is only one example of structures with non-aligned asperities usable in the context of the invention.
  • Another example is constituted by so-called "seasoned” structures which are distinguished essentially by sharp angles and no longer rounded.
  • the plate 1 which can be provided with a light 5 intended for hanging the display, is placed on a loading table, then there is, if necessary, a label 6, and then the objects in this example consisting of a large central ball 7 and a series of small peripheral balls 8.
  • the plate is then transferred to the lower plate of a laminating machine, the upper heated plate of which supports a transparent film which can be a polyethylene film coextruded with its adhesive. In other cases, it may be a polyvinyl chloride film but then it is necessary to provide, on the plate, a heat-adhesive varnish which can be an acetate-based varnish, the plate in front then be punctured to achieve permeability.
  • the film adheres to the plate by enveloping the objects to be conditioned, by means of a suction carried out under the plate.
  • the display is thus obtained in its final form, as illustrated in FIG. 3, where we see the ball 7 wrapped in film 9 which adheres along the corrugations to the sheet of paper 3.
  • the plate 1 has acquired, thanks to the biondulated paper 3, a perfect rigidity and flatness, while the porous or perforated cardboard plates used until now had no rigidity or flatness and could therefore lay any a series of problems, for their storage, seizure and transport, as well as for their loading on the loading table and their handling on the machine platform.
  • the balls 7, 8 placed on the paper 3, thanks to the undulations of this paper, are held in position, which is essential during the transfer of the loaded plate from the loading table to the laminating tray.
  • the display is of a very improved aesthetic, poorly visible on the drawings, on the one hand thanks to the very appearance of the biondulated paper, and on the other hand thanks to the rigorous positioning that can be done objects that can, for example, be arranged, as is the case here, to form a very precise geometric figure.
  • aesthetics, for a display of this kind is essential commercially.
  • FIG. 4 shows another embodiment according to which the plate 10 is divided into 16 elementary plates, one of which 11 is shown in FIG. 5.
  • the 16 elementary plates include a zone 12 in which the cardboard can be printed and another zone 13 in which the cardboard is covered with biondulated paper in the same manner as above.
  • the biondulé paper is arranged in 4 continuous bands 14 each ensuring the overlap of 4 zones 13 of the same line of elementary plates.
  • the packaging operations are carried out as for the plate of FIG. 1.
  • the objects to be conditioned shown in FIG. 5 are three small cylindrical objects such as electric cells.
  • the laminating operation must be followed by a cutting operation to separate the 16 elementary plates.
  • FIG. 6 represents a third embodiment which is generally used to obtain larger packages.
  • the plate 16 consists essentially of a porous or perforated cardboard 17 provided with impressions at its upper part, cardboard on which the sheet of paper has been glued only on the lower zone 18 intended to receive the products.
  • the plate 19 is placed on a larger counter plate 20 which is itself breathable, for example by means of perforations, and which can naturally receive impressions.
  • FIG. 8 shows how, after conditioning, the film 22 successively covers the counter plate 20, the plate 19 with its biondulated paper and one of the pencils 21.
