Definitions

  • the invention relates to a container with a bottom, side walls and lid a folded and glued cardboard blank, with one made of a plastic film formed inner bag.
  • Packaging from a cardboard container with a plastic inner bag have become known under the name bag-in-box and are, for example used for packaging liquid goods such as milk.
  • the cardboard packaging serves on the one hand to protect the inner bag from mechanical Injuries and is better stored and due to their outer shape transportable.
  • the inner bag is used for this packaging fixed to the bottom of the cardboard wrapping.
  • the invention is therefore based on the object of a container at the beginning to create mentioned type that can be manufactured inexpensively and itself especially for packaging free-flowing bulk goods in powder, grain and Flake shape is suitable.
  • the cardboard blank leads to the solution to the object according to the invention in the area of the side walls coated with the plastic film and at least is separated from the plastic film in the area of the cover, so that the Inner bag can be closed independently of the lid by the plastic film.
  • the cardboard blank is also preferred in the area of the bottom of the plastic film Cut.
  • the container according to the invention enables the combination of the properties a plastic bag with those of a cardboard packaging in optimal Wise.
  • a suitable choice of plastic film results packaging with excellent barrier properties against gases and water vapor.
  • the film thickness can be significantly reduced without the risk of tearing or other mechanical damage.
  • the result of this resulting material savings lead on the one hand to a cost reduction, on the other hand, there is a uniform material with a cardboard content of 95% and more, so that disposal without prior material separation is possible.
  • the lid of the container can be opened and closed again easily Closure, for example by arranging a tear strip, be designed in the form of a hinged lid.
  • Closure for example by arranging a tear strip, be designed in the form of a hinged lid.
  • Another possibility an easy to open and reclosable closure offers a push-through opening on the container side in the area of the lid.
  • the plastic film can improve the barrier properties and / or the mechanical strength in a known manner by vacuum deposition of ceramic materials, metals and others, the barrier properties be coated by plastic film improving materials.
  • the plastic film can consist of any suitable plastic.
  • Preferred plastics are polyester or a polyolefin, in particular polypropylene.
  • the possibly coated plastic film expediently has a thickness of approximately 5 to 40 ⁇ m, the weight of the cardboard blank is preferably between approximately 120 and 600 g / m 2 .
  • a material suitable for producing the cardboard blank can, for example made of cardboard, with the arrangement of an - especially adhesive - intermediate layer made of plastic, e.g. from polyolefins of the series of polyethylenes, is covered with printed paper.
  • the container according to the invention is particularly suitable as packaging for free-flowing bulk goods, especially food in powder, grain and Flake shape.
  • the preferably sealable plastic film results in an airtight seal Packaging with good storage properties for food.
  • a container shown in FIG. 3 in the form of a cuboid is made of a only cardboard blank 10 shown in Fig. 1 by folding along accordingly fold lines 18 embossed on the container edges.
  • the cardboard blank 10 has bottom flaps 12, side wall parts 14 in a known manner as well as cover flaps 16, which in a manner known per se to form Bottom 22, side walls 24 and cover 26 are glued together.
  • a the side wall parts 14 is additionally equipped with a side wall bracket 20, those in the finished container with the adjacent side wall part 14 is glued.
  • Both side wall parts 14 can also each have a side wall tab Have 20, which are directed outwards in the finished container and the inside of which are sealed or glued to each other.
  • a plastic film 28 - for example a polyester film - laminated.
  • the coating of the cardboard blank 10 with the plastic film 28 extends to the side wall parts 14.
  • the plastic film 28 from the cardboard blank 10 separated and extends over to form an excess the bottom flaps 12 and the top flaps 16 also.
  • the container which is still open in FIG. 2 with an open inner bag 30 is placed on a Filling station loaded with contents. After filling, the plastic film 28 to form a sealed seam 32 for the closed inner bag 30 shaped. The container is then finished by gluing the cover flaps 16 to the cover 26.
  • This cover 26 can be designed in various ways, for example as a reclosable cover with a tear strip like it is known in the art, or as a push-through opening on the container side in the area of the cover 26.
  • the production of the laminate from the cardboard blank 10 and the plastic film 28 can, for example, continuously by merging one the preformed cardboard blanks 10 containing cardboard tape with a Plastic film tape take place, whereby in the tape running direction x on the cardboard blank 10 desired laminated and non-laminated zones A, B are formed become.
  • the laminated zones A and the unlaminated Zones B of the cardboard blank separated by a border line s.
  • This Border line s is on the side wall parts 14 at a short distance b Fold line 18 of the bottom flaps 12 and the top flaps 16.
