Definitions

  • Injection moulded container for food products said container comprising a portion of recycled plastic material
  • the current invention relates to an injection moulded container which is suitable for food products and which comprises portions of recycled plastic materials.
  • a second aspect of the current invention is to provide a plastic packaging as mentioned in the opening paragraph which has a simple manufacturing process.
  • a third aspect of the current invention is to provide a plastic packaging as mentioned in the opening paragraph which allows for many different forms.
  • an injection moulded container comprising a bottom, a sidewall extending upwardly from the bottom and an upper rim defining a container opening arranged at the upper edge of the sidewall, said container comprising an inner functional barrier layer and a first injection moulded portion, said inner functional barrier layer comprising a bottom portion and a side wall portion and said first injection moulded portion comprising a side wall portion and an upper rim portion, said first injection moulded portion being injection moulded from a food grade plastic material and being injected in a first injection moulding step to join to the inner functional barrier layer such that the inner functional barrier layer and the first injection moulded portion together provide a sealed inner surface of the injection moulded container
  • the container further comprises a second injection moulded portion, said second injection moulded portion being injection moulded in a second step, being arranged outside the inner functional barrier layer and comprising a recycled plastic material.
  • a large portion of the container can be made from non food grade recycled material.
  • recycled materials which are not food grade certified may be used in food containers if they are kept separated from food contact by a functional barrier layer.
  • the functional barrier layer could be provided by many different types of functional barrier materials as will be known to the person skilled in the art.
  • the term functional barrier material should, in the context of the current invention, be understood as a material which prevents undesired chemicals contained in the recycled plastics material of the second layer from wandering out of the recycled plastics material and through the layer with the functional barrier material in a quantity which is undesirable.
  • the functional barrier material could be different types. In a case where a light contamination is present, a rather simple functional barrier material could be provided. In a case where a more significant contamination is present, a stronger functional barrier material would be needed.
  • One typical functional barrier material would be ethylene vinyl alcohol (EVOH).
  • EVOH ethylene vinyl alcohol
  • PET PolyEster or Polyethylene terephthalate
  • PET polyethylene terephthalate
  • AIOx Aluminium Oxide
  • Other suitable films with or without suitable coatings or layers will also be known to the person skilled in the art. However, in certain cases, it might be enough to just provide a clean layer of plastic, for example Polypropylene (PP), on one or both sides of the recycled plastics material layer.
  • PP Polypropylene
  • the person skilled in the art will be able to test if a potential barrier material is suitable when considering the food product and the degree of contamination of the recycled material of the second layer.

  • the inner functional barrier layer is provided as one or more foil elements which are folded and/or assembled into a container like shape with one or more gaps and/or one or more overlapping areas between adjacent portions of the one or more foil elements and in that the first injection moulded portion is arranged to fill the one or more gaps and/or cover the one or more overlapping areas.
  • the gaps in the barrier material are filled by a clean material.
  • the barrier layer should overlap the clean material a certain amount to ensure that contaminants in a material located adjacent the clean material does not wander through the clean material and onto the exposed surface of the clean material. Hence, it will be typical that the barrier layer overlaps the clean material a certain distance.
  • the certain distance could be at least 1 times the thickness of the container, or at least 2 times the thickness of the container or at least 3 times the thickness of the container.
  • the barrier layer can be arranged such that it overlaps itself to reduce the gap between adjacent portions of the barrier layer. However, even in these cases, in some applications it will be desireable to cover these overlapping areas with clean material to further reduce the risk of contaminants in the recycled material from passing through the overlapping areas of the barrier layer.
  • the foil elements are made from a flexible foil element. In one embodiment, the foil elements are made from a material which bonds to the material of the first injection moulded portion during the injection moulding process.
  • the first injection moulding material could comprise multiple different materials which are co-injected. In this case multiple materials are injected simultaneously via an injection nozzle to form an outer skin and an inner core.

  • first injection moulded portion will be cooled by the time the outer foil layer is added.
  • the outer foil layer will not attach so well to the first injection moulded portion and having it extend across the first injection moulded portion so that it can attach to the second injection moulded portion on both sides of the first injection moulded portion ensures that the outer foil layer is firmly attached to the container without any loose edges.
  • the outer foil layer can also attach to itself if the inner and outer layers of the outer foil layer can join together when heated.
  • a layer of adhesive could be applied to the outer surface of the first injection moulded portion prior to applying the outer foil layer to the first injection moulded portion.
