Definitions

  • the subject of the present invention is packaging, in particular for vegetables.
  • the object of the invention is to provide packaging, in particular for fruits and vegetables, which has good mechanical strength, allowing its presentation in a well-defined geometric form, which allows ventilation of the product, and which optionally allows protect it from light.
  • the packaging it relates to has a bottom in tray shape obtained by thermoforming or stretching an element perforated top made of synthetic material, and a cover itself made made of heat-sealable synthetic material.
  • the bottom of the packaging in the form tray is made from a grid, a mesh or a net synthetic material.
  • the bottom of the packaging in tray shape is made from a perforated film.
  • the tray shape is achieved by an increase dimension of the grid, the mesh, the net or the film by an operation longitudinal or bi-axial stretching, cold or hot, which allows to obtain an at least localized elongation of the synthetic material, favoring the resistance of stretched areas.
  • the stretching operation is carried out using one or more molds, positive or negative, cold or hot. This operation allows to obtain a tray whose dimensions in width, length, and depth, correspond to the mold used and the volume required to house the products to be packaged. Other stretching or molding processes can be used.
  • the trays advantageously having a shape rectangular can also be stored in cases rectangular, for transport to the point of sale.
  • the boxes can be stacked, which improves the conditions of presentation for sale.
  • the cover is made of a heat-sealable plastic film having openings.
  • the plastic film which is fixed by thermo-welding on the tray, receives the identification elements of the product supplier, and also provides protection for products contained in the tray with respect to light rays.
  • the cover is made by a grid, a mesh or a net made in one heat-sealable synthetic material.
  • the different constituent strands of a grid, a mesh or a net, intended to make a tray are identical.
  • some of the strands making up a grid, mesh or net have a section larger than that of the other strands and / or the grid, the mesh or the net constituting a tray has solid parts of material in place of certain mesh openings.
  • the diameter of the strands grid, mesh or net constituting a tray is between 0.1 and 3mm, while the mesh size is between 1.5 and 30mm.
  • the tray-shaped bottom has a peripheral rim used to support and fixing of the cover.
  • the cover is secured to the bottom, made in the same flat element as the tray, and connected to the tray along one of its edges by a fold line allowing its folding back to the closed position.
  • the tray according to the invention can be unitary, or include several juxtaposed cells closed by the same cover.
  • a method of manufacturing a package according to the invention consists, from a reel of grid, mesh, net or film, to unwind this reel by printing an advance in steps, to be trained at a post at minus one tray, to be filled at the post following the tray (s) with the products to be packaged, to be produced at the post following the fitting of the cover which is unwound from a coil, to be thermally welded at the station following the lid on the tray and to cut the trays and the covers in relation to the strips in which they were made and to evacuate the full and individualized trays to a storage area or grouping.
  • the filling of the packaging is made during the manufacturing process itself.
  • the filling of the packaging can take place in a different location from the place of manufacture of the tray.
  • the method according to the invention consists, from of a reel of grid, mesh, net or film, to unwind a plug from this reel by printing an advance in steps, to be trained at a post at minus a tray, to cut the trays relative to the strip in which they were formed, and to stack the trays before placing them transfer to a place where they are successively filled with the products to be packaged and closed by a cover fixed by welding thermal.
  • Figure 1 shows a package with a bottom 2 in form of tray, obtained by thermoforming a blank consisting of a grid comprising oblique wires 3 and 4 respectively. thermoforming is carried out with care of a flange 5 oriented towards outside.
  • the tray 2 is closed by a film 6 made of material melt.
  • Figure 2 shows a variant of this packaging in which the tray 2 comprises a plurality of cells 7.
  • These cells 7 can either be closed individually and held together, after filling, or cut to provide individual trays.
  • Figures 3 to 6 show several embodiments of plastic grid or mesh formed by crossing wires 3 and 4.
  • Figure 3 shows a square mesh grid
  • Figure 4 represents a rectangular mesh grid
  • Figure 5 shows a diamond mesh grid
  • FIG. 6 represents a grid constituted by crossing of three sons 3, 4, 10 from three sectors;
  • FIG. 7 represents a blank consisting of a film 8 in which are provided with perforations 9.
  • FIG. 8 represents a grid in which are provided, in the zones forming the edges of a tray, wires 13 and 14 in diameter larger than the wires 3 and 4 provided on the rest of the grid surface.
  • a tray obtained from a blank of Figure 8 is shown in the figure 10.
  • Figure 9 shows a grid blank in which some of the openings are closed by material 15.
  • a tray obtained at from a blank in Figure 8 is shown in Figure 11.
  • FIG. 12 represents an installation for the manufacture of a packaging according to the invention.
  • a grid such as one of the one defined above is wound on a reel 16, which is unwound according to a step advance.
  • the grid 17 passes successively to a thermoforming station 18 equipped of a punch 19, at a filling station 20 of product 22 at condition, then at a sealing station 23 using a film 24 unwound from a coil 25, the fixing being carried out by heat sealing the film 24 on a tray 2.
  • the trays then pass to a post cutout 26 which separates the sealed trays from one another.
  • the completed packages are then removed to a station 27.
  • Figure 13 shows an installation in which the same elements are designated by the same references as above.
  • several trays are simultaneously produced by thermoforming, these trays being just after training, separated from each other at a position 26. These trays are then stored, for example by stacking, at a extension 28.
  • the trays 2 are then transported to a place of filling where they successively undergo filling 20 using of items at a post 20, then a closing operation by sealing at a post 23, before evacuation to a place of storage and grouping at item level 27.
  • the invention provides a great improvement to the existing technique by providing packaging of simple structure, which can be easily carried out, including on the place for packaging products, with good performance mechanical, and able to protect products from light.
