Definitions

  • the present invention relates to gas-tight containers, in particular for food products or other products intended to undergo heat treatment, of the "tub" type.
  • Dishes prepared in the food industry are generally packaged in packages formed by trays made of aluminum foil, synthetic resin or various complexes, such as cartons with film coating.
  • Cooking of culinary preparations takes place before their introduction into the trays. The latter are closed after cooking, which causes, due to transfers, the risk of soiling and contamination.
  • an automatic closure device for packaging for food preparations with deferred consumption by using on the one hand the expansion and exhaust effects of hot air or steam during the operations. cooking, and on the other hand the contraction during cooling to ensure by non-return valve the hermetic sealing of the packaging by eliminating pollution and loss of aromas occurring during the closing operation, characterized by the combination on the one hand of a capacity formed by a double partitioning at the preferentially axial part of a package with upper and lower perforations and on the other hand by the positioning of a non-return valve or sealing washer in the intermediate space, it being specified that said washer has peripheral orifices and the like, and is placed freely to carry out a vertical displacement from top to bottom and bottom up, either to free the orifices, or to close them with guidance to prevent any lateral movement which could disturb the evacuations and obturations.
  • French patent No 89 17 528 describes a tray provided with a tongue hinged on the edge, folded inwards after filling with food and before sealing the sealing film, said hinged tongue having on its horizontal face a perforated seat in which a drop of composite resin is deposited which becomes porous at a determined temperature.
  • this packaging requires, in addition to a resin becoming porous, a complex sealing tool capable, simultaneously, of sealing the sealing film all around the tray and all around the seat, and of perforating the film at the precise location where it is located.
  • the drop of fusible composite resin thanks to a point provided for this purpose.
  • the complexity of the tray itself makes the production of molds delicate and expensive, and the hinged tongue requires additional manipulation for its positioning.
  • the object of the present application is a tray allowing the elimination of these drawbacks. Indeed, it does not require an articulated tongue and is therefore simpler and less expensive.
  • the manufacturing mold is also cheaper to manufacture and the sealing tool does not require a point to perforate the film at the location of the drop of fusible resin, the sealing taking place automatically by the sole effects of the heat treatment usually applied. to a tray and cooling.
  • the container according to the invention comprises a rim body hermetically sealed with a film and having a hole in the rim, characterized by a layer of a substance, having a melting point between 65 ° C and 150 ° C, interposed between the film and the edge part around the hole.
  • the tray, Figures 1 to 3 consists of a body 2 and a hot-melt valve formed by a single orifice 10 with a diameter of 0.7 to 2 mm formed on the rim 3 of the body 2, preferably as close as possible to the internal edge 11, a thin layer of hot-melt resin 12 being deposited all around the orifice, on said rim.
  • the tray After filling with food products, the tray is sealed with a film 7 welded around its periphery.
  • the film 7 lifts under the effect of the overpressure which is created inside, which frees the orifice 10 and allows degassing (arrow 13, FIGS. 2 and 4) products and the evacuation of the internal pressure of the tray which takes place through this orifice while the hot-melt resin 12 is in the liquid state.
  • the air, the water vapor and the gases 5 may escape through the fuse valve, the orifice bringing the inside of the tray 2 into communication with the outside.
  • the thin layer of hot-melt resin can, in another example of application, be coated on the internal face of the film 7, either in marked locations corresponding to the location of the orifice (s) 10 of the tray ( Figures 4 and 5) , or in a uniform layer over the entire surface of the film.
  • the vacuum created in tray 2 by temperature difference adds to the preservation qualities of food products, which are immune to the risk of oxidation. It is also for example that the colors of green vegetables are perfectly preserved.
