Definitions

  • the invention relates to a folding box made of cardboard, which consists of a blank folded into a cuboid, in which a hinged lid is formed with a locking tab provided for locking insertion into the box, in particular for accommodating tea infusion bags.
  • Such folding boxes made of cardboard or cardboard are known and are used for packaging a wide variety of goods, including tea infusion bags.
  • the cardboard blank should be folded and glued to the folded box with the least amount of packaging material, and high strength should be achieved.
  • a closure which is firm for sale is expected, in which the consumer immediately recognizes that the packaging has not yet been opened.
  • the packaging should be aroma-tight.
  • the consumer must be able to close a opened package in such a way that the goods are still protected against the influence of moisture and atmosphere and against loss of aroma.
  • the invention is based on the object of proposing a folding box of the simplest cut, which can be produced inexpensively in a simple manner with savings advantages in packaging material and nevertheless ensures high stability and aroma tightness, even after opening.
  • a folding box of the type mentioned at the outset is characterized according to the invention by a rectangular cardboard blank with four transverse folding lines for producing a cuboid with open end faces, which are flush-fitted by means of fitted separate end-face covers, each of which has a rectangular cardboard blank with connecting flaps that can be bent at right angles to the four free sides are produced, the lid in the cardboard blank for the manufacture of the cuboid being formed by two spaced-apart punching lines which only partially penetrate the cardboard and which are brought together in the closure flap which is arranged in the free edge of the cardboard blank and with one pre-formed slot corresponds, the punching line of which only partially penetrates the carton.
  • a box longitudinal part is folded from an extremely simply constructed rectangular cardboard blank, the open end faces of which are closed flush again by cardboard blanks of very simple construction, which form end face covers. Any complicated shape of cut is avoided.
  • the design of the tear-open lid in the cardboard blank is also structurally simple, in that the pre-formed punching lines are brought together in the closure flap arranged on the outer edge, which can be inserted into a corresponding slot for reclosing the box. The aroma tightness is guaranteed by the pre-formed punching lines Only partially penetrate the cardboard so that the folding box is completely closed until it is opened by the consumer.
  • the end face covers are preferably made of a material of higher cardboard weight than that of the cut for the cuboid, so that a very high stability is achieved, which in turn makes it possible to use a cardboard material of substantially lower cardboard weight for the longitudinal box part. This results in considerable savings in packaging material, which are not only noticeably noticeable in the course of manufacture, but also in disposal after the contents of the pack have been used up.
  • the cardboard weight of the end covers is preferably 230-280 g / m2, in particular 275 g / m2, and that of the cuboid is 200-250 g / m2, in particular 225 g / m2. In this way, considerable material savings are achieved with good stability.
  • the end face cover can be glued to the cuboid over the entire contact surface in order to increase the stability. This is much more advantageous than folding and gluing the end covers in place, which would also be conceivable. In addition, the full adhesion also improves the aroma tightness.
  • the end covers have overlapped corners for the same purpose, which have the advantage that when the connecting brackets are angled, the corner regions are compressed and thus there is also a seamless, tight connection in these problem areas when gluing.
  • a special cardboard material with a higher barrier property can be used, in particular a recyclable packaging cardboard with a water vapor barrier, built up from fresh fiber cardboard with a chlorine-free coating.
  • a material is commercially available under the name Biocoat-FA.
  • the main area of application for this carton is the packaging of greasy, non-wet goods, aroma-tight packaging of dry, hygroscopic goods.
  • the fat density was classified in class 2 according to DIN 53116.
  • Biocoat-FA is rated as very good in terms of its recyclability.
  • the Biocoat-FA can be glued using starch glue.
  • the cardboard folding box that can be produced from the two blanks according to FIGS. 1 and 2 has three individual parts, namely the cuboid blank 1 and two End face cover blanks 2 for closing the open end faces of the cuboid.
  • the cuboid blank 1 is provided with four transverse fold lines 3, 4, 5, 6, which represent crease edges during the manufacture of the cuboid. After its manufacture, the latter has a front side 7 and an upper side 8, in which a lid 9, which can be opened and closed again after the folding box has been opened, is formed.
  • two spaced-apart punching lines 10, 11, which only partially penetrate the carton are formed on the front 7 and top 8, which are brought together in a closure flap 12, which is arranged in the free edge 13 of the carton blank and corresponds to a pre-punched slot 14 whose punching line only partially penetrates the box.
  • a closure flap 12 which is arranged in the free edge 13 of the carton blank and corresponds to a pre-punched slot 14 whose punching line only partially penetrates the box.
  • the open sides of the cuboid are closed flush by two end covers, which consist of a blank according to FIG. 2 of the drawing.
  • This is of simple rectangular shape and has four connecting straps 15, 16, 17, 18 on its edges, which can be bent at right angles. Overcut corners 19 are formed between adjacent connecting straps and are pressed together when the connecting straps 15 to 17 are angled.
  • the end face covers are glued in by gluing over the entire contact surface of the Connection tabs carried out with the corresponding surfaces of the cuboid, so that a completely sealed folding box is created.
  • the front covers are made from a blank 2 according to FIG. 2 of the drawing, which has a higher cardboard weight than the rectangular blank 1.
  • the cardboard weight of the front cover blank is 275 g / m2
  • the box weight of the square blank is 225 g / sqm. This enables a significant reduction in the total weight of the packaging and thus the amount of material used.
  • a recyclable packaging board with a water vapor barrier constructed from fresh fiber board with a chlorine-free coating, is used as the board material with high barrier properties and gas-tightness against loss of aroma.
  • Such a material is commercially available under the name Biocoat-FA.
  • the main areas of application for this carton are the packaging of greasy, not wet filling goods and aroma-tight packaging of dry, hygroscopic goods.
  • the fat density was classified in class 2 according to DIN 53116.
  • Biocoat-FA is rated as very good in terms of its recyclability.
  • the Biocoat-FA is glued using starch glue.
