Definitions

  • the subject of the present invention is a packaging for packaging products under a transparent film, a process for producing this packaging, and a device for carrying out this process.
  • a first package known as SKINPACK comprises a cardboard plate whose face intended to receive the product is coated with a layer of synthetic material, such as polyvinyl chloride. After depositing the product on the plate, a sheet of synthetic material, brought to a temperature at which the material is malleable, is applied to the face of the plate on which the product is deposited, while carrying out a suction through the plate. Due to the malleable nature of the sheet, it follows the shape of the product and presses it against the plate, while adhering to it, taking into account the temperature at which it is located.
  • a package of this type is described in the preamble of document FR-A-1,531,066.
  • Document US-A-3 083 106 describes a package, in particular for food products, produced from two plastic films between which the products are placed, and which are made integral with one another by a peripheral weld .
  • Another package known as a blister comprises a cardboard plate coated with a film of synthetic material, such as polyvinyl chloride and a shell of synthetic material, such as rigid polyvinyl chloride, molded in the shape of product.
  • a film of synthetic material such as polyvinyl chloride
  • a shell of synthetic material such as rigid polyvinyl chloride
  • Another package comprises a lower shell in which a product is placed, a plate being placed without being attached to it, between two shells or between a shell and a plate made of synthetic material, for example rigid polyvinyl chloride. , joined to each other at their periphery by a high frequency welding operation.
  • this packaging has the advantage of having an inviolability much higher than that of the previous packaging, it has the disadvantage of being very expensive to use since it is necessary to have molds specific to each product to thermoform the hulls, and it requires a sophisticated welding installation.
  • Other disadvantages of the packaging reside in the fact that it is bulky, that the plate does not adhere to the shells and that the packaged product does not adhere to the plate.
  • the present invention aims to remedy these drawbacks by providing a packaging of simple design, with a reduced implementation price, ensuring excellent inviolability of the packaged products, while allowing excellent viewing of these products.
  • the packaging it relates to, of the type comprising a cardboard plate or the like intended to serve as a support for one or more products to be packaged, the face of which receives the product or products receives a coating of a layer of synthetic material, and a first sheet of synthetic material which, intended to cover the upper face of the plate and the product or products resting thereon, with fixing thereon, under the action of heat and with application of a depression through the plate, this first sheet serving to retain the product or products on the plate, is characterized in that the first sheet projects beyond the peripheral edge of the plate and in that it comprises a second sheet of synthetic material which, intended to cover the underside of the plate, is fixed to the first upper cover sheet by a peripheral weld on it beyond the edge of the plate, this second sheet protecting the connection zone between the edge of the plate and the first sheet by preventing access to this zoned.
  • the packaging according to the invention has all the advantages of packaging of the SKINPACK type, since the plate adheres to the upper covering sheet, which intimately follows the product or products deposited on the plate, while having excellent inviolability, due to the peripheral weld formed between the upper and lower covering sheets, which prevents access to the connection zone between the edge of the plate and the upper sheet, and avoids the risks of delamination of these two elements.
  • the packaging has an opening for hanging from a hook of a display
  • an opening is made in the plate, before fixing the covering sheets, and a weld is made between the upper and lower covering sheets in below the edge of the opening in the plate. This last weld prevents any risk of delamination of the upper sheet and the plate from the opening.
  • the upper and lower covering sheets are made of the same material.
  • the material constituting the upper and lower coating sheets is chosen to make a connection of these by heat sealing or by pulse welding.
  • the facing faces of the upper and lower coating sheets may be based on polyethylene, ionomer resin known for example under the brand SURLYN, or a butadiene-styrene copolymer, such as those known under the K-RESIN and STYROLUX brands.
  • polyethylene ionomer resin known for example under the brand SURLYN
  • a butadiene-styrene copolymer such as those known under the K-RESIN and STYROLUX brands.
  • the plate on which the product to be conditioned is deposited is flat.
  • the plate on which the product to be packaged is deposited has a peripheral edge obtained by cutting and creasing the side from which the plate is cut, and folding the edges at 90 °, this rim being covered by the covering sheet. upper, which keeps it in good shape.
  • One method for producing this packaging consists in depositing one or more products on a plate, the upper face of which is coated with a layer of synthetic material, in covering the plate with an upper sheet of coating of synthetic material, with an area greater than that of the plate, the contacting between the sheet and the plate being carried out after the sheet has been brought to its softening temperature and by exerting a vacuum through the plate.
  • this method consists in covering the plate with a lower covering sheet, and finally in welding the upper and lower covering sheets beyond the peripheral edge of the plate.
  • the plate In the case where the plate has a peripheral rim, it is first positioned inside a frame ensuring the shaping of the rims, from which it is removed before welding of the lower covering sheet.
  • the packaging represented in FIGS. 1 to 3, and designated by the general reference 2, is intended for the packaging of a tool constituted in this case by a screwdriver 3.
  • This packaging comprises a cardboard plate 4 the upper face of which receives, by printing, decorative patterns and / or indications concerning the description and use of the tool.
  • This plate 4 which has an opening 5 intended for hanging the packaging from a hook, is coated on its upper face with a layer 6 of synthetic material.
  • a sheet 7 of upper covering and a sheet 8 of lower covering each of surface greater than that of the plate. Firstly, the upper covering sheet 7 is brought by elevation of temperature to its softened state, and is applied to the plate 4 with gentle depression through it. The sheet 7 then marries the tool and adheres to the plate 4.
  • the sheet 8 is then fixed to the sheet 7 by a peripheral weld 9 produced by temperature rise or by pulses, this weld 9 being formed outside the edge peripheral of the plate 4.
  • a weld 10 between the two sheets is produced below the opening 5 of the plate 4.
  • Such packaging has the advantage that the tool adheres to the plate 4, that the sheet 7 also adheres to the plate 4 and follows the shape of the tool, and that the weld between the two sheets 7 and 8 ensures excellent tamper-evident packaging.
  • Figure 4 shows an alternative embodiment of the packaging of Figures 1 to 3 in which the same elements are designated by the same references as above.
  • This packaging differs from the previous one in that the plate 4 has a peripheral rim 12 forming an angle with the plane of the plate, this rim 12 being held in place by the upper covering sheet 7.
  • a plate intended for the positioning of several plates comprises, at the level of each plate a peripheral frame 13 ensuring the shaping of the flanges 12 and their holding before positioning of the upper covering sheet 7.
  • the bearing plate the reference 14 includes perforations 15 making it possible to create a depression through the plates 4 during the operation of placing the upper covering sheet on the plates.
  • Figures 6 and 7 show a device for producing these packages, respectively seen in perspective and seen in longitudinal section.
  • This device comprises a first station 16 where trays 14 intended to receive several plates 4 positioned by pins not shown in the drawing or by frames 13, are loaded with products 3.
  • Each tray 14 is then moved to be brought to a support 17 associated with a lifting cylinder 18.
  • the support 17 brings a plate 14 into contact with an upper covering sheet 7 unwound from a roller 19.
  • Contact between a plate 14 and the sheet 7 is carried out at the level of a heating block 20 bringing the material of the sheet to a malleable state and with care of a vacuum through the support 17.
  • the invention brings a great improvement to the existing technique by providing a packaging of simple design, ensuring excellent protection of the packaged products, and having a very good inviolability, while being obtained using a very economical process and device.
