Definitions

  • the present invention relates to methods for packaging products formed by pouring into a thermoformed wrapper of a blister-pack, and is concerned particularly with a method of the type in which the wrapper comprises a film of thermoplastics material having cells which are thermoformed and are each intended to receive a metered quantity of a respective product.
  • a method is disclosed, for instance, in FR-A-2 411 132.
  • the product is poured into a mould of a material which can withstand the temperature, for example, a metal mould, and is subsequently put into the cells of the wrapper of the blister-pack after the product has been cooled to a temperature which the thermoplastics material of the wrapper can tolerate.
  • the object of the present invention is to provide a process of the type specified above which does not have the aforementioned drawbacks.
  • the present invention provides a process of the type specified above, characterised in that said thermoplastic material is chosen of a type to which the pouring temperature is harmful and in that the product is poured in the molten state into each cell of the wrapper while simultaneously cooling the wrapper by a flow of liquid coolant in contact with the outer surface of the wrapper.
  • the product is formed by being poured directly into the wrapper of the pack.
  • a further subject of the present invention is constituted by a machine for packaging products formed by pouring into a blister-pack, the pack comprising a film of thermoplastic material with cells which are thermoformed and are each intended to receive a metered quantity of a respective product, comprising:
  • a pack of the type generally known in the art as a blister-pack is generally indicated 1.
  • the pack 1 comprises a wrapper 2 formed by thermoforming a sheet of thermoplastics film, for example, polyvinyl chloride (PVC).
  • PVC polyvinyl chloride
  • the flat surface of the sheet of thermoplastics film is deformed locally to form cells 3 each of which is intended to receive a respective product, for example, a pastel formed by pouring.
  • the cells 3 are intended to receive pastels formed by the pouring of sorbitol.
  • the sorbitol is heated to a temperature of the order of 85-90°C.
  • the polyvinyl chloride (PVC) of the wrapper 2 can normally withstand a temperature of about 70°C but is deformed at higher temperatures.
  • the blister-pack illustrated in Figure 1 further includes a sealing strip 4 which closes the cells 3.
  • both the wrapper 2 and the sealing strip 4 are normally made from sheets of thermoplastics film which are unwound from corresponding supply reels.
  • the product of the packaging operation is also in the form of a sheet which is subsequently cut and punched to form packs of the type illustrated in Figures 1 and 2.
  • the pack 1 includes three parts two of which have cells 3 while the other has two flat faces which may be used, for example, for trade marks and information about the packaged product.
  • thermosetting station for the first sheet 11 of thermoplastics film unwound from the first reel 10 is generally indicated 12.
  • a filling station is interposed between the thermoforming station 12 and a sealing station 14 with which is associated a second reel 15 for supplying a second sheet 16 of thermoplastics film.
  • a collecting station, for the finished product, generally indicated 17, comprises a reel 18 on which the sheets 11, 16 are wound after they have passed through the sealing station 14.
  • the filling station 13 includes a channel 13a which extends in the direction of displacement of the first sheet 11 of thermoplastics film between the forming station 12 and the sealing station 14.
  • the channel 13a has a depth greater than the depth of the cells formed in the first sheet 11.
  • the channel 13a has an inlet end 13b for the first, thermoformed sheet 11.
  • the channel 13a has longitudinal ribs 13c and is overlain, close to the inlet end 13b, by a station 13dfor pouring metered quantities of the product to be packaged.
  • a pump 13f which supplies the channel 13a with a liquid coolant is connected to the channel 13a by a pipe 13e.
  • the intake side of the pump 13f is connected to a cooler, 13g which is supplied with the coolant discharged from the channel 13a through an aperture 13h in the bottom of the channel 13a close to the sealing station 14.
  • the bottom of the channel 13a has a plurality of ventilation apertures 13i to which a suction pump 13/ is connected.
  • the first sheet 11 of thermoplastics film is supplied from the first reel 10 to the thermoforming station 12 where the flat surface of the sheet 11 is deformed locally to form longitudinal rows of cells of the type indicated 3 in Figures 1 and 2.
  • thermoformed first sheet 11 Downstream of the thermoforming station 12, the thermoformed first sheet 11 is passed along the channel 13a so that the side walls of the channel support the longitudinal edges of the sheet 11 during its passage along the channel 13a.
  • the machine according to the invention is intended to package products formed by pouring into a blister-pack which includes four pairs of rows of cells 3 separated by intermediate flat portions of the thermoformed sheet 11.
  • the longitudinal ribs 13c projecting from the bottom of the channel 13a support these intermediate portions of the thermoformed sheet 11.
  • metered quantities of the product to be packaged are poured into each cell 3 of the wrapper 2 formed by thermoforming of the first sheet 11 of thermoplastic film, while the wrapper itself is immersed in the bath of liquid coolant which is present in the channel 13a.
  • each cell 3 is in contact with the coolant which is kept at a temperature below the level which produces harmful phenomena, such as deformation of the wrapper itself.
  • the pump 13f supplies the channel 13a with low temperature coolant from the cooler 13g.
  • the wrapper In its movement towards the sealing station 14 along the channel 13, the wrapper is kept immersed in the bath of coolant so as to keep the outer surfaces of the cells 3 in contact with the coolant until the product therein has set.
  • the coolant is discharged from the channel 13a and is directed to the cooler 13g so as to form a closed circuit for the coolant of which the channel 13a constitutes a part.
  • the circulation of coolant in the channel 13a is facilitated by the movement of the first sheet 11 the cells 3 of which project into the channel and act as blades to push the coolant from the inlet end 13b towards the aperture 13h.
  • thermoformed sheet 11 is kept in sliding contact with the side walls of the channel 13a so as to prevent the coolant leaving the channel itself.
  • thermoformed sheet 11 Downstream of the discharge aperture 13h, the thermoformed sheet 11 is made to continue along the channel 13a towards the sealing station 14, until it reaches the apertures 13i through which drops of coolant adhering to the surface of the thermoformed sheet are removed by the suction pump 13/.
  • the second sheet 16 of thermoplastics film, supplied by the second reel 15, is applied and heat-sealed to the first, thermoformed sheet 11 so as to close the openings of the cells 3 housing the poured products.
  • the packaged product is wound in a strip onto the collecting reel 18, preferably after it has undergone an initial cutting and/or punching operation so as to allow the separation of the pairs of rows of cells present in the product leaving the sealing station 14, and to allow the subsequent longitudinal subdivision of the strips wound on the reel 18 to form packs of the type illustrated in Figures 1 and 2.
