Definitions

  • the present invention relates to the vacuum packaging of food or other products in presentation trays on each of which is attached a sealing film welded on the edges thereof.
  • French patent 2,565,552 in the name of the Applicant describes an apparatus comprising a sealed welding enclosure which is constituted by two inverted bells capable of being separated from each other for the establishment of a tray of packaging in the lower bell so that it rests on the edges thereof via an external rim provided on this tray.
  • the sealing film, placed above, is then welded by applying a welding head provided inside the upper bell of the corresponding enclosure. Furthermore, during this operation, a vacuum is created inside the welding enclosure.
  • the subject of the present invention is a method and apparatus which are designed so that products packaged in display trays can protrude very widely above them in order to be presented in an apparent and very attractive manner to prospective buyers.
  • the first object of the invention is a method of vacuum packaging a food or other product in a presentation tray of lesser height on which is attached a thermo-plastic film welded on its edges, characterized in that : - before welding of this film inside a vacuum-tight enclosure, the portion of this film which is inside this enclosure is heated, while the tray to be closed and its contents are placed below this film, - then the raising of this tray is carried out in a position such that its content sinks into the corresponding portion of the film so that it completely envelops the projecting part of this product, - And after having carried out under vacuum the welding of the film on the peripheral rim of the corresponding tray, the vacuum is eliminated, so that the corresponding portion of the film is applied closely to the projecting part of the product.
  • the present invention also relates to an apparatus specially designed for the implementation of this process inside a welding enclosure formed by the union of two movable bells inverted and which contains a sealing head as well as a support plate serving as support for each tray during the sealing operation.
  • This device is characterized in that: the upper bell of the welding enclosure contains a movable heating plate for the portion of the closure film which is situated inside this enclosure, the support plate is vertically movable between a lower position situated at the level of the arrival position of each tray for which the latter and its contents are below the closure film and an upper position corresponding to the operation of solder, and for which the rim of the corresponding tray is at the level of the closure film, while the contained product protrudes above, - the means for controlling and driving the various parts being arranged so as to successively carry out the following operations: . closing the welding enclosure and lowering the heating plate of the closing film, . raising this heating plate, accompanied by raising the support plate in the welding position, . opening of the welding enclosure and evacuation of the closed tray.
  • This device comprises a sealed welding enclosure which is formed by the union of two inverted bells 1 and 2. These are movable along their vertical axis XY and they are actuated by drive means not shown making it possible to bring them together for the closing the welding enclosure and moving them aside for the opening thereof.
  • the closing plane of these two inverted bells corresponds to the plane along which the thermo-plastic closing film 3 is disposed on its portion 4 located inside the present device.
  • This film comes from a feed roller 5 and passes over a deflection roller 6 before it passes through this device.
  • a tray 7 which is intended to serve as a support for each packaging tray 8 when it is in the present device.
  • This plate is carried by a vertical operating rod 9 actuated by drive means not shown so as to be moved between: - A lower position for receiving a packaging tray, this position being at a sliding plate 10 located on the side of the introduction of the trays 8 and on which each of these can slide under the effect of a suitable drive means, for example a pusher 11, - And an upper position corresponding to the welding operation ( Figure 4), this position being at a sliding plate 12 located on the side provided for the evacuation of each tray.
  • This fixed sliding plate 12 for evacuation is located at a distance H1 from the portion 4 of the film closing, this distance being equal to the height of each packaging tray, that is to say the distance between its outer rim 13 and its bottom.
  • the feed plate 10 it is located at a distance H2 from the portion 4 of the closure film, this distance being greater than the overall height of the assembly constituted by a presentation tray 8 and the product P placed in the latter, which protrudes very largely above the corresponding tray, since this is the mode of packaging provided in this case.
  • the lower bell 1 also contains a tank 14 of lesser height and which is movable in the vertical direction.
  • the upper edge of this tank is intended to serve as a support for the rim 13 of the corresponding tray 8 for presentation during the welding operation.
  • This tank is carried by one or more rods 15 actuated by drive means not shown.
  • the upper bell 2 contains a welding head 16 which is hollow and the lower edge 17 of which is capable of ensuring the welding of the film 4 on the rim 13 of a presentation tray 8.
  • This welding head comprises suitable heating means, for example electric resistors 18.
  • a heating plate 19 is provided which is arranged above the portion 4 of the closure film and parallel to it.
  • This plate includes suitable heating means, for example electrical resistances. It is carried by an operating rod 20 actuated by drive means not shown.
  • control and drive means of the various moving parts of the present apparatus are arranged so as to carry out the following successive operations:
  • the two inverted bells 1 and 2 are brought against each other so as to close the welding enclosure.
  • the portion 4 of the closure film is then trapped inside this enclosure by being pinched between the edges of the two bells 1 and 2. This gives the formation of a sealed enclosure subdivided into two parts A and B by the closing film 3.
  • the tank 14 accompanied the lower bell 1 in its raising movement while the support plate 7 remained stationary in its lower position.
  • the upper edge of this tank is then simply placed below the peripheral rim 13 of the corresponding presentation tray 8.
  • the upper part A of this enclosure is placed under vacuum, then it is the same for its lower part B. This has the effect of pressing the portion 4 of the closing film against the heating plate 19, the lower face of which is then substantially in the closing plane.
  • the heating plate 19 having been put into operation, this results in a softening of the corresponding portion 4 of the closure film.
  • the heating plate 19 is then raised in its retracted position against the bottom of the weld head 16. Then the support plate 7 is itself raised in its upper position, while the tank 14 is itself raised so that its upper edge clamps the peripheral rim 13 of the corresponding packaging tray 8 against the closure film.
  • the raising of the support plate 7 has the effect that the product P placed in the presentation tray 8, and which projects widely above the peripheral rim thereof, comes to press in the portion 4 of the closure film which is next to it. As this portion of the film is then in the softened state due to its prior heating, this causes its deformation in the form of a sort of pocket 21 enveloping the projecting part of the product P.
  • the welding head 16 ensures, by its lower edge 17, the welding of the thermoplastic film 3 on the peripheral rim 13 of the packaging tray.
  • the vacuum previously existing in the welding enclosure is first removed in its part A, then in its part B. This has the effect of thermoforming the corresponding portion 21 of the film on the projecting part of the product P. This portion of the film thus closely follows the surface of the product P by forming a fold 22 in the bottom of the presentation tray.
  • the two inverted bells 1 and 2 are then separated from one another to open the welding enclosure.
  • the presentation tray 8 which has just been closed, can be transferred by sliding onto the fixed discharge tray 12. This transfer can be ensured by exerting a pull along arrow F on the front end of the film 3 since the tray 8 remains attached to this film. However, this transfer could also be ensured by any other appropriate means.
  • the support plate 7 is then lowered to its lower waiting position in order to be able to receive a new packaging tray to be closed.
  • the present process therefore makes it possible to package a product P projecting widely above the peripheral rim 13 of the corresponding presentation tray 8. Consequently, the product is presented in a very attractive form for potential buyers because it is perfectly visible through the closure film which wraps it tightly.
  • Such a packaging process can be used advantageously for a large number of food products, for example for delicatessen products such as ham, pâtés, etc.
  • the device designed for Implementation of the present process can be integrated into a more complex packaging machine, for example a machine such as that described in French application 86-09995 of July 9, 1986 in the name of the Applicant.
  • the present device can then replace the welding station provided in the machine which is the subject of this patent application, in which case the fixed sliding plates existing on both sides must undergo a shift in the height direction to adopt the positions provided for the plates 10 and 12 of this device.
