Definitions

  • the invention relates to a cardboard folding box consisting of one the four Main sides of a cuboid blank with two over tabs with the Main sides connected end face covers, the cut over four Main fold lines in five fields of the same length forming the main sides of the box is divided, of which the two outer fields when closed Cover the box and the field that covers the outside as well as the field Adjacent field to form a shorter than the folding box itself trained cover with the cardboard only partially penetrating punching lines are provided in an adjoining an elongated pull tab Converge the locking tab.
  • packaging for food and especially for tea infusion bags of great importance that after filling the packaging a solid
  • the packaging is closed so that the goods inside are aroma-tight are packed. Nevertheless, the consumer must open the first time Packaging have the opportunity to close them again so that the Goods against the influence of moisture and atmosphere as well as against Aroma losses are protected. Further requirements for such packaging arise in the context of their manufacture. This should be done with the least Effort for packaging material should be possible, furthermore that for packaging used cardboard blank folded and folded into a folded box be glued, and have a high strength.
  • the German Utility model G 94 07 036 proposed a folding box, the Cardboard on the inside of the box with one aroma-proof and coated as a water vapor barrier lacquer surface is. Such a paint treatment increases the cost of manufacturing Blanks, furthermore there can be problems in the disposal of such two-layer cardboard packaging.
  • the folding box according to the German utility model G 94 07 036 consists of three parts formed with a rectangular, connected over a total of four fold lines Blank, through which the long sides of the folding box are formed, and two separate cuts for the front covers. Through the The use of three blanks results in this folding box relatively many columns.
  • the prior art also includes US Pat. No. 4,436,206, from which one Folding box is known, which can be manufactured from a single blank.
  • the end covers are already an integral part of the Cut, with tabs are also formed, so the individual fields to be able to glue together.
  • the invention has for its object to provide a suitable for the aroma-tight packaging of food in particular folding box that is inexpensive to produce in one operation and can be opened easily.
  • the box consists of a single blank, that both end covers and at least four of the tabs are integrally formed on the narrow edges of the main pages via fold lines, and that one end of the tear tab ends flush with the side edge of the cover formed by one of the punched lines.
  • one end of the pull tab is flush with the one of the stamped lines formed on the side edge of the lid, this can be done first opening the lid along the one in the locking flap run converging punching lines cleanly, without it becoming one Tear diagonally or across the punch lines and thus loss of aroma when The packaging may come back on.
  • the folding box can be fold from a relatively simple cardboard blank into a cuboid, the front sides of which are initially open, in one piece with the blank connected end covers are closed flush, as is the case for considered to be known from US 4,436,206. As for the production of the Folding box only a single cut is required, processing is on the usual packaging machines possible.
  • a further simplification of the cut shape contributes if, according to a Design of the folding box a total of four tabs directly on the narrow margins on the main pages, and a total of two additional tabs on the Outer edges of the front covers are formed. Furthermore, the Face covers preferably molded onto the field that the Bottom of the box forms.
  • a slot is preferably provided for inserting the locking tab. This is punched through according to an advantageous embodiment, so that the Locking tab as soon as you use the lid for the first time can slide the slot in.
  • the Locking tab in the field covering the outside, with the pull tab extends parallel to the main fold lines and on at least three sides partially penetrating punch lines is limited.
  • the pull tab improves the Aroma tightness of the folding box before opening. It also prevents the locking tab unintentionally releases too early, and thus an early one Air exchange occurs between the inside of the pack and the environment.
  • the Tear-off tab while maintaining all-round edge areas within the surface of the overlapping field.
  • Another advantage of this measure is that that the closure flap is not near the edges of the folding box, and therefore does not accidentally come off prematurely.
  • the first time solving the Lid can be run along the converging in the closure flap Carry out cardboard only partially penetrating punching lines safely without it unintentional tearing outside of these punching lines can occur.
  • the invention proposes that the pull tab be shorter is as the width of the lid and that one end of the pull tab is flush ends with one side edge of the lid. This also ensures that the first tearing of the lid along that in the closure flap converging punching lines is executed cleanly without that tearing can occur diagonally or transversely to the punching lines.
  • the folded box shown in Fig. 1 serves in the folded state preferably the packaging of food e.g. Tea infusion bags.
  • the cuboid folding box is provided with a lid 1, which is a Stamping line 2 acting in the manner of a hinge is pivotable.
  • the cover 1 itself is through a further punch line 3 into a top 4 and a side surface 5 divided.
  • the lower edge of the side surface 5 is through a closure tab 6 formed, which is in a slot 7 of another side surface 8 can be inserted.
  • the cover 1 is closed, the side surface is therefore covered 5 of the lid 1 part of the fixed side surface 8 of the folding box.
  • the lid 1 does not extend over the entire length of the folding box, which is why edge regions 9 remain which contribute to strengthening the folding box.
  • the folding box consists of a single blank 10. Its cardboard weight should be between 200 and 250 g / m 2 .
  • the cardboard used is a recyclable packaging cardboard with a water vapor barrier, made of fresh fiber cardboard with a chlorine-free coating. The main areas of application for these cardboard materials are the packaging of greasy, not wet filling goods and aroma-tight packaging of dry, hygroscopic goods.
  • the individual surfaces of the folding box are glued with felt starch glue.
  • This consists of five equally long fields 11, 12, 13, 14, 15 for the main sides of the box, two end covers 16, 17 and six tabs 18 - 23 together.
  • the five fields 11, 12, 13, 14, 15 are separated from one another by four main fold lines 2, 3, 24, 25.
  • the individual fields are each angled at 90 ° to each other, which is because more fields 11 -15 than main pages are provided, leads to the fact that the outer one when the box is closed Field 15 completely overlaps the other outer field 11.
  • the end face covers 16, 17 are in one piece in the exemplary embodiment arranged over further fold lines on the narrow edges of the field 12, and are also bent inwards by 90 ° so that they face the end faces of the cuboid.
  • the tabs 18 and 19 are with the inner surface of the field 14, which forms the top of the folding box, glued, whereas the tabs 20-23 with the inner surfaces of the end covers 16, 17 are glued.
  • the outer field 15, which overlaps the other outer field 11, and further the field 14 adjacent to it are for the formation of the cover 1 with two converging in the closure flap 6, the cardboard only partially penetrating punch lines 26, 27 provided. Separate these punch lines 26, 27 hence the material of the lid 1 from the edge areas 9.
  • Another Punching line 28 extends the punching lines 26, 27 up to the sealing tab, which is why it extends at right angles to the two punching lines 26, 27.
  • the Punching line 28 also defines one edge of one in the middle of field 15 trained tear tab 29, the other edge by another Punching line 30 is defined. While the punching line 30 is made straight throughout is, the punched line 28 has an indentation 31, the shape of the Locking tab 6 defined.
  • the tear tab 29 is shorter than the width B. of the lid 1.
  • the punch lines 26, 27, 28 and 30 are formed with a step in the cardboard material and are only pre-formed so far in the cardboard material that an effortless Tearing open along these punch lines is possible. At the same time, provided the punch lines are still intact, an airtight seal and thus the complete aroma tightness of the folding box guaranteed.
  • the tear tab 29 is on the Gripped end 33 and torn open towards the other end 32, until the tear tab 29 is completely separated. Then there is the locking tab 6 free and can be gripped to cover 1 still along the punch lines 26, 27 to solve until it can be swung open completely, such as this is shown in Fig. 1.
  • the lid 1 is pivoted down again and the locking tab 6 inserted into the slot 7. To facilitate this, the slot 7 is from the beginning completely punched through.
