Definitions

  • the present invention relates to a method and a device for filling a container with a liquid product, said container being of a collapsible type and having a compartment which is defined by flexible walls and whose volume is dependent on the relative position of the walls, said walls comprising two opposite side walls which, in the state of the container before filling, flatly abut against each other.
  • composition of the protective atmosphere is such as to inhibit growth of bacteria, which results in the shelf life of the packaged foods being extended.
  • the protective atmosphere can act to prevent growth of aerobic or anaerobic microorganisms.
  • the protective atmosphere is not allowed to contain oxygen (O 2 ).
  • Nitrogen (N 2 ) has been found to be a suitable gas for preventing growth of aerobic microorganisms in foods.
  • the protective atmosphere may also contain carbon dioxide (CO 2 ).
  • CO 2 has, like N 2 , the property of inhibiting aerobic growth. It has further been found that CO 2 can inhibit anaerobic growth. The reason for this is not fully elucidated, but in one explanatory model this is caused by carbon dioxide reducing the pH, thus providing an environment which inhibits the growth of the anaerobic microorganisms.
  • liquid products have up to now only to a limited extent been packaged in containers with a modified atmosphere.
  • the reason is that it has been found difficult to be rationally and economically capable of providing the containers with said modified atmosphere.
  • WO2006/021839 discloses a process for aseptic packaging of a sterile liquid. According to the process described therein, containers are formed from a strip of material around a filling tube which is arranged, not only for supply of the sterile liquid, but also for supply of an inert gas. The inert gas is used to form a barrier that prevents penetration of air.
  • a method for filling a container of a collapsible type with a liquid product having the features as defined in claim 1 or 3 .
  • Embodiments of the methods are stated in the dependent claims 2 and 4 - 11 .
  • the invention concerns a device for filling a container of a collapsible type with a liquid product having the features as defined in claim 12 .
  • Embodiments of the device are stated in the dependent claims 13 - 15 .
  • a method for filling a container of a collapsible type with a liquid product has a compartment which is defined by flexible walls and whose volume is dependent on the relative position of the walls, said walls comprising two opposite side walls which, in the state of the container before filling, flatly abut against each other.
  • the method comprises the steps of opening an inlet by separating opposite inlet portions of said side walls, supplying a protective atmosphere to a volume defined by the open inlet, relative to the container inserting a filling nozzle in the inlet, supplying said product to the compartment of the container through said filling nozzle, relative to the container withdrawing said filling nozzle from the inlet, and sealing said inlet.
  • a method which in a rational way allows the provision of an extended shelf life of the product contained in the container.
  • This is achieved by producing a modified atmosphere in the container of a collapsible type.
  • a protective atmosphere in one step being supplied to a volume which is formed by opening the inlet of the container, it is ensured that no air enters the container in the subsequent step when the filling nozzle is being inserted in the inlet. Instead, an amount of protective atmosphere is pressed into the container, which protective atmosphere is mixed with the product during the subsequent filling operation.
  • the protective atmosphere contains carbon dioxide
  • a long-term admixture to the product which acts to reduce the pH so as to counteract the growth of anaerobic microorganisms.
  • the protective atmosphere contains, for instance, nitrogen
  • the nitrogen is supplied in a pressurised and compressed state and will thus expand in the container. This expansion can be made to continue after completion of the filling process, whereby the nitrogen released from the product thus acts to expel any air that has entered the container.
  • the subsequent sealing of the container it will consequently be possible to ensure that the headspace of the container does not contain any air, which has a positive effect on the shelf life of the product. It will thus be possible to ensure that a protective atmosphere forms a modified atmosphere in the later sealed container.
  • the step of, relative to the container, withdrawing the filling nozzle from the inlet can be followed by the step of supplying a protective atmosphere to a volume which is defined by the inlet above the surface level of the product. This ensures that there is no air left in the current volume after withdrawal of the filling nozzle.
  • the invention also suggests a method of filling a container of a collapsible type with a liquid product.
  • the container has a compartment which is defined by flexible walls and whose volume is dependent on the relative position of the walls, said walls comprising two opposite side walls which, in the state of the container before filling, flatly abut against each other.
  • the method comprises the steps of opening an inlet by separating opposite inlet portions of said side walls, relative to the container inserting a filling nozzle in the inlet, supplying said product to the compartment of the container through said filling nozzle, relative to the container withdrawing said filling nozzle from the inlet, supplying a protective atmosphere to a volume which is defined by the inlet above the surface level of the product, and sealing said inlet.
  • the step of, relative to the container, inserting a filling nozzle in the inlet can be followed by the step of supplying a protective atmosphere to the container.
  • the protective atmosphere can be supplied through the filling nozzle or alternatively through a nozzle arranged separately from the filling nozzle.
  • the protective atmosphere may contain carbon dioxide or nitrogen. By letting the protective atmosphere contain carbon dioxide, optionally in combination with some other gas such as nitrogen, a protective atmosphere is produced, which inhibits growth of anaerobic microorganisms.
  • the protective atmosphere may have a density that is higher than the density of air. This means that it will be easier to ensure that the protective atmosphere remains in the volume defined by the inlet.
  • a container which is made of a laminated container material containing a core layer of mineral-filled polyolefin. Containers made of such a container material have been found to have a high permeability to gas.
  • the container can also be made of a laminated container material containing a gas barrier layer.
  • the protective atmosphere contains a gas component which is supplied in a compressed and pressurised state, said gas component, after completion of the filling of the container, being allowed to expand in the container, the step of sealing the inlet of the container being performed before said gas component has finished expanding.
  • a device for filling a container of a collapsible type with a liquid product is suggested.
  • the container has two opposite side walls, which flatly abut against each other in the state of the container before filling and which comprise opposite inlet portions, which are to be separated to open an inlet.
  • the device comprises an opening means for opening said inlet by separating said opposite inlet portions, and a filling nozzle, which is to be inserted into said inlet to supply said product to the container.
  • the device further comprises a nozzle for supplying a protective atmosphere to a volume defined by the open inlet.
  • a device for filling a container of a collapsible type with a liquid product which device makes it possible to achieve an extended shelf life of the packaged product by producing a modified atmosphere in the filled container.
  • the device comprising a nozzle for supplying a protective atmosphere to the volume defined by the open inlet, it will be possible to ensure that no air is pressed into the container when inserting the filling nozzle in the open inlet.
  • protective atmosphere push away air contained in the volume defined by the inlet above the surface level of the product after withdrawal of the filling nozzle.
  • the container can then be sealed, whereby the protective atmosphere forms a confined modified atmosphere which extends the shelf life of the product.
  • the nozzle is integrated in said filling nozzle.
  • the nozzle can be separately arranged to said filling nozzle.
  • the opening means comprises a pair of suction cups for engaging said inlet portions by suction. This results in simple separation of said inlet portions to open the inlet of the container.

  • the protective atmosphere that is used according to the present invention can have various compositions and consist of, for example, nitrogen, carbon dioxide or a combination thereof.
  • the protective atmosphere can have a density that is higher than the density of air. This facilitates in particular the supply of protective atmosphere to said volumes V 1 and V 2 , and it is ensured that the protective atmosphere is retained in them.
  • the container 2 has a required impermeability to gas to ensure that the modified atmosphere produced by the protective atmosphere is retained in the container 2 . It has been found that a container material containing chalk-filled polyolefin has a good permeability to gas and therefore the inventive container 2 can be made of such a container material.
  • the impermeability to gas can be further improved by the chalk-filled polyolefin material, or some other mineral-filled polyolefin material, being included as a core layer in a container laminate which also contains a gas barrier layer of, for example, EVOH, EVA or PET. Also other container laminates are conceivable, for instance containing a core layer of pure polyolefin and a gas barrier layer.
