Definitions

  • the invention is directed to a folding box with two alternately articulated broad side walls and narrow side walls and top flaps hinged to the top and bottom of each broad side wall and dust flaps articulated top and bottom to each narrow side wall, the lid flaps having a width of at least approximately 2/3 of the width of the Narrow side walls and the dust flaps have a width smaller than half the width of the wide side walls, according to the upper handles of claims 1 and 2.
  • Document EP-A-0 079 847 discloses such a folding box.
  • lid flaps and the dust flaps are such that they no longer completely cover the cross-section of the folding box.
  • cover flaps and / or the dust flaps with embossings into which the flaps fit with their edge regions when they are folded open to form a powder-tight seal.
  • the punching machines In the manufacture of the blanks used for such folding boxes, the punching machines must be provided with special stamping tools in addition to the punch knives that are usually present. In addition to the resulting increased technical outlay on machinery and the wear and tear of additional tools, there is also time-consuming and additional set-up time and work involved in the production of the blanks, which is not necessary with only punched blanks.
  • the object of the invention is to provide a folding box to be closed in a powder-tight manner with shortened lid and dust flaps from an embossed punched cardboard blank.
  • this object is achieved according to the invention in that at least the dust flaps on the head side each have a die cut starting from the respective longitudinal flap edge, which is either inclined at an angle to approximately half the width of the dust flaps, with the two die cuts in the folding box blank being inclined in opposite directions to each other and the inclination and distance to the broad side edges of the respective dust flap are dimensioned such that when the folding box is closed, the longitudinal side edge of the cover flap first folded onto the dust flaps cuts both die cuts and each in covers the area facing away from the longitudinal edge of the dust flap, or which extends up to half the width of the dust flaps parallel to their broad side edges at a distance which is slightly greater than the width of the top flap that was first folded onto both dust flaps.
  • the invention makes it possible to produce folding box blanks with shortened lid and dust flaps in conventional punches, without special setup work for embossing tools being necessary, which allow the formation of powder tightness of the embossing boxes to be produced from the blank. Without additional embossing, the required powder-tightness of the folding box is achieved with one punch cut in each of the dust flaps.
  • a similar effect which also leads to a powder-tight folding box, also occurs in the embodiment in which the die cuts are parallel to the broad side edges the dust flaps are designed with a distance that is slightly larger than the width of the cover flaps.
  • the die cuts are then parallel to and at a slight distance from the longitudinal side edge of the cover flap that was first folded onto the dust flaps. They are not covered by this cover flap, so that when the two cover flaps are glued, there are distortions within the dust flaps due to the usual pressure applied, which causes the edges of the die cuts to be placed against the longitudinal edge of the cover flap that was unfolded first.
  • the punch cuts are inclined at an angle of 55 ° to 85 ° with respect to the longitudinal edge of the dust flaps, as the invention provides in one embodiment.
  • the punch cuts are rectilinear.
  • the folding box labeled 1 overall in FIG. 2 is erected from the folding box blank partially shown in FIG. Of the Folding box blank 2 consists of cardboard and is punched on conventional punching machines and then erected and used on conventional folding box gluing machines.
  • the folding box blank 2 and the folding box 1 consist of two alternately articulated wide side walls 3, 4 and narrow side walls 5, 6.
  • an adhesive flap (not shown) on a narrow side or wide side wall, as is known from conventional folding boxes , be provided.
  • cover flaps 7, 8 are articulated via a crease.
  • Dust flaps 9, 10 are articulated on the narrow side walls 5, 6 above and below via a crease line.
  • top hinged top flaps 7, 8 and dust flaps 9, 10 are shown.
  • the respective articulation crease lines are shown as a continuous line 11.
  • the cover flaps 7, 8 have a width B 1 which is at least approximately 2/3 of the width B of the narrow side walls 5, 6.
  • the width B 2 of the dust flaps 9, 10 is smaller than half the width B 3 of the wide side walls 3, 4.
  • the wide side walls 3, 4, the narrow side walls 5, 6, the cover flaps 7, 8 and the dust flaps 9, 10 are each of the same size , so that the erected and hose-shaped blank represents a cuboid folding box 1. This is shown in a top view in FIG.
  • FIG. 2 thus shows a top view of a folding box 1 that is only partially closed, that is, except for the cover flap 8 that is still to be folded.
  • the folding box blank 2 is erected and hosed as is known from conventional folding box cuts. Subsequently, the dust flaps 9 and 10 and then the first cover flap 7 are folded inwards for closing. The outer cover flap 8 is then folded over. The dust and lid flaps are glued to one another like standard folding box packaging with adhesive strips or adhesive dots.
  • FIGS. 3 and 4 differs from those according to FIGS. 1 and 2 only in that the punch cuts 21, 22 parallel to the broad side edges 16, 17; 18, 19 of the dust flaps 9, 10 are executed.
  • the distance A of the punch cuts 21, 22 to a broad side edge 17 or 18 is dimensioned such that the distance A is slightly larger than the width B 1 of the cover flap 7, which is first folded onto both dust flaps 9, 10, and that the other Punch cuts 21 and 22, when the folding box 1 is erected and tubed, run parallel to the longitudinal side edge 20 of the cover flap 7 first folded onto the dust flaps 9, 10.
  • the elements shown in FIGS. 3 and 4 are identical to those shown in FIGS. 1 and 2 and therefore provided with the same reference numerals.
  • the production, ie the erection, tubing and gluing, is carried out as in the exemplary embodiment according to FIGS. 1 and 2.
