Definitions

  • the present invention relates to an apparatus and a method for closing a filled container.
  • the invention relates to an apparatus and method for closing thin walled containers made by container molding by means of blowing pressure.
  • preforms made of a thermoplastic material for example, preforms made of PET (polyethylene terephthalate), fed to different processing stations within a blow molding machine.
  • a blow molding machine has a heating device and a blowing device, in the region of which the previously tempered preform is expanded by biaxial orientation to form a container. The expansion takes place with the aid of compressed air, which is introduced into the preform to be expanded.
  • the procedural sequence in such an expansion of the preform is explained in DE-OS 43 40 291.
  • the basic structure of a blowing station for container molding is described in DE-OS 42 12 583. Possibilities for temperature control of the preforms are described in DE-OS 23 52 926.
  • the containers are filled and then closed by means of a closing device, for example screwed on a lid or applied a sealing cap.
  • a closing device for example screwed on a lid or applied a sealing cap.
  • fruit juices or iced teas are filled into the thin-walled containers in a so-called "hot-fill” method, in which the contents are heated to kill any germs present in the contents before they are filled in. After heating, the hot contents are filled into containers
  • a disadvantage of this known method is that the volume of the filling material on cooling is reduced (so-called volume shrinkage), however, since the container is closed, it forms a trap Vacuum, which causes the thin-walled container to deform in.
  • a drop of liquid nitrogen is added to the container via a nitrogen blanket before it is closed leads to a nitrogen gas with a larger amount as the drop volume and thus generates an excess pressure, which compensates for the resulting negative pressure by the cooling medium.
  • the disadvantage of this known method is that the pressure generated by the nitrogen is difficult to regulate. As a rule, the nitrogen drop is therefore over-dimensioned to ensure that the negative pressure is compensated by volume shrinkage due to the overpressure, as a rule the drop is therefore oversized. Owing to the oversizing of the nitrogen droplet, an overpressure is created in the container. This has the consequence that the walls of the container must be made larger, so that the container reliably withstands the additional load due to the overpressure. Correspondingly, more material must be used for the container walls than without overpressure in the container, as a result of which the material weight to be used and the associated material costs rise.
  • the object of the present invention is to provide a device improved in this respect and an improved method for closing a filled container.
  • the device according to the invention for closing a filled container comprises a gripping device which grips the container and thereby holds it on support means which are formed on the container, for example a circumferential neck ring, a Pilver proof ring or circumferential grooves.
  • a gripping device may be, for example, a pliers known in the art.
  • the gripping area is arranged on the bottom side of the mouth area, which is thus freely accessible for closing.
  • the wear takes place by a closing device.
  • the device further comprises a pressure chamber, wherein the closing device is disposed within the pressure chamber.
  • the device has a pressure device, for example a connection line to a compressed air supply, with which a defined internal pressure can be built up in the pressure chamber.
  • the pressure chamber is formed and limited by movably arranged pressure chamber means, which can be arranged, for example, in a rest position so that the bottle can be supplied or removed. If a build-up of pressure is required, the pressure chamber means can be moved in order to come into contact with a container area below the mouth area. You can for example be arranged to be vertically movable.
  • a drive may be provided for the height drive or the height movement may be derived in known manner from other movements, for example from a rotary movement, if it is a device of rotating design.
  • the arrangement of a pressure chamber around the mouth region of the container gives the possibility of producing an internal pressure deviating from the ambient pressure, namely an overpressure, in the mouth region and thus also in the free lumen of the filled container.
  • the arrangement of the closing device in this pressure chamber the container can be closed under the pressure.
  • the pressure remaining in the container after the beverage has cooled can advantageously be set relatively accurately, the pressure preferably being set so that no overpressure remains in the container, but substantially the ambient pressure.
  • a pressure reduction means a relief of the container, the walls of which can be dimensioned correspondingly thinner, which advantageously material savings and thus cost savings can be achieved.
  • a bell is sealingly lowered onto a neck ring provided on the container, and the mouth region is thus encapsulated by the ambient pressure.
  • the support ring serves to transport the preform / container through the blow molding machine and the filling machine, where it can be attacked.
  • the pressure chamber means can also come to rest on or at this neck ring in the present invention. The problem is that for reasons of material savings and thus the cost reduction of the support ring is dimensioned smaller and thus provides an ever smaller area for sealing.

  • the pressure chamber is formed in each case by a bell-shaped chamber member and an annular chamber member.
  • the annular element, the ring device is arranged below the mouth region and surrounds the container.
  • the bell-shaped element can then be lowered and come to rest on or on the ring element to form the pressure chamber.
  • An additional ring device can be dispensed with in that the gripping device at least partially forms the ring device. It is particularly preferred that the gripping device completely forms the ring device, and the gripping area is formed encompassing 360 °.
  • the bell could have a lower edge area that complements the gripping device to 360 °.
  • a typical gripping device are the pliers known in the art, which are typically used e.g. encompass a circumferential region of about 180 °. The still required 180 ° could make the bell with a lower projection. This would e.g. make a redesign of known gripping devices dispensable
  • a further advantageous embodiment of the invention provides that the pressure chamber hermetically seals the mouth region, so that the internal pressure generated in the pressure chamber can be maintained in a simple manner. Alternatively, pressure would have to be built up against leaks of higher power.
