Definitions

  • the invention is based on a method for sterilizing a packaging material formed from a thermoplastic plastic sheet by stretching according to the preamble of claim 1.
  • a sterilization method known, for example, from FR-A-1192697
  • a packaging material in the form of a tube is sterilized, from which only after the sterilization treatment, the container is completely formed.
  • the packaging material used to form the packaging tube has a paper web on which a plastic layer adheres. Due to the carrier function of the paper layer, this packaging material or packaging tube remains stable during the thermal sterilization treatment. Even if the packaging tube is only formed from a plastic film, there is no risk of deformation as long as the treatment temperature is below the softening point of the plastic in question.
  • DE-A-2839543 discloses a method for sterilizing cup-like packaging containers formed by stretching a thermoplastic plastic sheet with a mixture of water vapor and air at a temperature of 250 ° C.
  • the heat transferred to the wall of the container can increase the temperature of the wall so that damage occurs in plastic containers.
  • An attempt is therefore made to get by with the shortest possible heat treatment time, but this entails the risk of an insufficient degree of sterility.
  • With a sufficiently long heat treatment however, in the case of packaging materials shaped like cups by thermoforming of a plastic film, reshaping occurs due to the release of the restoring tension in the walls, which render the containers unusable because of the reduction in volume and the irregular appearance.
  • the invention has for its object to make from a thermoplastic sheet by stretching packaging, as specified in the preamble of claim 1 and known from FR-A-1 192697, in the walls of which reset voltages are present with a high degree of sterility to make them sterile.
  • This object is achieved according to the invention in that, in the case of a finished, shaped packaging material designed as a cup-shaped container, the outside of the container is held in a form-fitting manner during the heat treatment of the inside of the container with a cooled, solid body which is adapted to the shape of the container.
  • the sterilization process for shaped packaging with the characterizing features of the main claim avoids the disadvantages stated in the prior art. It can be carried out in a simple manner by means of a device specified in claim 3, which in a configuration according to claim 4 or 5 has a simple structure and can advantageously be integrated into a packaging machine.
  • FIG. 1 shows a machine for shaping, sterilizing, filling and closing cup-like containers in simplified longitudinal section
  • FIG. 2 shows a device for sterilizing containers in a further configuration compared to FIG. 1 in longitudinal section.
  • thermoplastic material for example polypropylene, polyvinyl chloride
  • containers 3 are drawn by stretching by thermoforming.
  • the containers 3, which have a frustoconical shape, are then sterilized on the inside, filled thereon, sealed with a cover film 4 and finally punched out of the web 1.
  • a packaging machine for performing these processing operations at successive stations to which the web 1 is fed step by step with a conveyor device (not shown) has a heating device 11 for plasticizing a section of the web 1, a molding device 12 with a die 13 for two containers 3, one Sterilizing device 14, a filling device 15 and a sealing device 16.
  • the sterilizing device 14, the filling device 15, the sealing device 16 and a cover film sterilizing device 17 are accommodated in a chamber 18, in which a sterile atmosphere with a little overpressure is maintained.
  • the sterilizing device 14 the other devices belong to the machine ne to the state of the art, which is why it is unnecessary to describe them here in more detail.
  • the sterilizing device 14 which is set up to sanitize the already cup-shaped containers 3, has a lower part 20 with two cavities 21, the shape of which corresponds to the outer shape of the containers 3, so that a container inserted therein lies with its outer wall against the wall of the cavities 21 .
  • the lower part 20 preferably has the same shape as the die 13 of the shaping device 12. It is attached to a rod 22 so that it can be raised and lowered for loading and unloading.
  • the lower part 20 is crossed by a plurality of channels 35 (only one shown) which are connected to a coolant inlet 36 and a coolant outlet 37.
  • a plurality of suction bores 33 open in the cavities 21 of the lower part 20 and are connected to a suction line via collecting bores 34.
  • the head piece 23 With the interposition of the film web 1 with the molded-in containers 3, it lies in the working position from below against a stationary head piece 23, which forms a closure for the containers 3 used in the cavities 21 of the lower part 20.
  • the head piece 23 has on its underside a recess 24 leaving a head space and two openings 25 directed into the cavities 21, to which a line 27 leading to a valve 26 is connected.
  • Connection lines 28, 29, 30 also lead to the valve 26, which lead to a steam generator 28, a sterile air source 29 and a suction pump 30.
  • projections for example cones, projecting into the cavities 21 can be arranged on the top plate 23.
  • the wall of the containers 3 When the containers are treated with steam in the overpressure region, the wall of the containers 3 is pressed firmly against the wall of the cavities 21, so that the wall of the containers 3 is cooled well.
  • the wall of the container 3 When using superheated steam at atmospheric pressure, the wall of the container 3 is drawn to the cavity wall by negative pressure, which is generated by suction of the air through the suction bores 33 and the collecting bores 34.
  • valve 26 switches off the steam supply line and opens the supply line 29 for sterile air at a pressure which is slightly above the pressure prevails in chamber 18.
  • the sterile air creates the necessary pressure compensation for lowering the lower part and rinses out the steamed container 3.
  • the containers 3 are briefly evacuated before venting.
  • the valve 26 connects the line 27 to the suction line 30 after the vaporization and before the ventilation. Both the evacuation and the flushing with sterile air dry the condensate water from the container wall.
  • the containers can be subjected to the treatment described above several times in succession in order to achieve a very high degree of sterility, for which purpose several stations in the machine in the direction of travel of web 1 are equipped with the sterilization devices described or similar.
  • a cooling device can also be used which directs cooling air or cooling water against the outside of the containers in a fine distribution by means of nozzles, while the inside is steamed. This configuration also has a simple structure with a good effect.
