Definitions

  • the invention relates to a method for sterilizing containers according to the preamble of the main claim.
  • a method of this type which has become known, for example, from DE-OS 28 39 543
  • a mixture of water vapor and air at a temperature of 250 ° C. is blown into the interior of the container to sterilize it.
  • the heat transferred to the wall of the container can raise 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.
  • DE-PS 23 39 128 has also made it known that the packaging material web is to be sterilized before it is formed into containers.
  • the degree of sterility obtained by this method is very high, but it happens again and again that when the containers are formed, pores which open can cause non-sterility by stretching the packaging material web on its surface. In particular, this occurs with packaging material webs made of mineral-filled or foamed plastics.
  • the sterilization process for packaging containers 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 a device specified in claim 4, which, in an embodiment according to claim 5 or 6, has a simple structure and can advantageously be integrated into a packaging machine. With an arrangement according to claim 7, there are the advantages that the sterile space of a packaging machine can be kept very small, since in such an embodiment the molding device can remain outside the same. This also makes pre-sterilization of the machine easier and easier to control before it is put into operation, because it is precisely the complicated structures of the molding device that require special attention during pre-sterilization.
  • 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 embodiment 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 each 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 is maintained with a little excess pressure.
  • the sterilizer device 14 the other devices of the machine belong to the prior art, which is why it is not necessary to describe them in more detail here.
  • the sterilizing device 14 which is set up to sanitize the already cup-shaped container 3, has a lower part 20 with two cavities 21, the shape of which corresponds to the outer shape of the container 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.
  • 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 2 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 container 3 When treating the container with steam in the overpressure area, the wall of the container 3 is pressed firmly against the wall of the cavities 21, so that the wall of the container 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 the vaporized 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 above-described or similar sterilizing devices.
  • containers that are provided with a label that a label is inserted into the cavity 21 prior to the lifting of the lower part 20 for receiving a container, the label of which is heat-bonded to the outside of the container during the heat treatment .
  • a cooling device can also be used, which directs cooling air or cooling water against the outside of the containers in fine distribution while the inside is being steamed. This configuration also has a simple structure with a good effect.
