Definitions

  • the present invention refers in general to the field of vacuum and/or protective atmosphere packaging and in particular to a method and to an apparatus for packaging products, in particular food products, in a vacuum and/or in a protective atmosphere, as well as to a container particularly suitable to be used for vacuum and/or protective atmosphere packaging.
  • Said packaging system according to the prior art has various drawbacks. In fact, once the tray is opened by the end user by removing the covering film, the contents of the tray must be consumed because the tray cannot be closed again.
  • the object of the present invention is to overcome the drawbacks of the prior art by providing a method for vacuum and/or protective atmosphere packaging that is versatile, efficient and able to allow high-speed, continuous production.
  • Another object of the invention is to provide an apparatus for vacuum and/or protective atmosphere packaging that is simple to make.
  • Yet another object of the present invention is to provide a container for vacuum and/or protective atmosphere packaging that is easy to package and that can be closed again after opening by the end user.
  • the peculiar characteristic of the invention is represented by the use of a container comprising a tray with a lid integral with/hinged to the tray. In this manner closing of the container takes place simply by lowering the lid on the tray.
  • the process of packaging must provide a first stage of semi-closing of the lid so as to leave a gap for removal of the air and/or for introduction of gas into the container, and a second stage of complete closing of the lid and of heat-sealing or sealing thereof to avoid tampering with the container and/or the product.
  • Such a package according to the invention offers the end user the possibility of opening and of subsequently closing it by wedging of the lid into the tray.
  • the apparatus 1 comprises a conveying station 2, a filling station 6, a semi-closing station 3, a station 4 for creating the vacuum and/or the protective atmosphere and for heat-sealing and a discharging station 5.
  • a lid 103 able to close the tray 101 hermetically, is connected integrally to a portion 102 of the upper edge of the tray 101.
  • the connecting portion 102 behaves as a hinge and the lid 103, rotating around the hinging axis 102, can pass from an opening position to a closing position of the tray 101.
  • the lid 103 is thermoformed together with the tray 101 and in normal conditions the lid 103 remains in the open position with respect to the tray 101.
  • the upper edge of the tray 101 and the peripheral edge of the lid 103 are able to engage mutually with each other by interference, to maintain the lid 103 in the closing position.
  • the empty containers 100 are conveyed from the conveyor belt 20 toward the filling station 6, disposed in two parallel rows, with the lids 103 completely open and disposed towards the outside. Even if in the Figures the containers 100 are shown disposed on two rows, they can be disposed on one or more rows.
  • the filled containers 100 continue their transfer on the conveyor belt 20 towards the semi-closing station 3. During this transfer the side bars 23 of the conveyor continue with two guide bars 31, convergent and inclined upwards. In this manner the bars 31 cause raising of the lids 103 of the containers bringing them towards the closing position.
  • Semi-closing of the container 100 takes place by means of shaped guides 34 suitably inclined downwards or by means of mechanical or pneumatic actuators 32 which are responsible for lowering the lid 103 onto the tray 101.
  • the filled and semi-closed containers 100 continue on the conveyor belt 20 towards the station 4 for creating a vacuum and/or a protective atmosphere and for heat-sealing.
  • the lids 103 of the containers remain beneath the parallel horizontal bars 33 which serve to keep the lids 103 in their semi-closed position.
  • a press comprising a lower half-mould 41 and an upper half-mould 42.
  • pneumatic means 43 for suction and introduction of gas and thermal means 44 for heat-sealing are provided on the upper half-mould 42.
  • the introduction means 43 introduce suitable gases into the container so as to create a protective atmosphere. According to the characteristics of the product contained in the containers 100, gases such as oxygen O 2 , carbon dioxide CO 2 and nitrogen N 2 can be introduced.
  • the edge of the container 100 is sandwiched between the lower half-mould 41 and the upper half-mould 42, closed hermetically and sealed by means of the thermal heat-sealing means 44, so as to avoid tampering with the container 100 and the product, before it reaches the end user.
  • the container 100 is made of particular plastic materials (easy open) which allow heat-sealing and easy opening of the container 100. In this way, if the consumer intends to use up the product in more than one time, there is the possibility of closing again by wedging the lid 103 of the container.
  • the apparatus 100 can provide a reel 70 of plastic film 71 which can be used in a per se known manner for closing of the trays 101, if said trays are not provided with a reclosable lid.
  • the reel 70 is disposed above and upstream of the station 4 for creating a vacuum and/or a protective atmosphere and for heat-sealing, whilst the waste film 71' is collected by a winder 42 disposed downstream of the station 4.
