Definitions

  • the invention relates to packaging made of cardboard or the like. for packaging one or more objects, with a blank that has a top surface, two side walls articulated thereon and a bottom wall consisting of two sections, the bottom wall sections having tabs on the one hand and slot-shaped recesses provided for receiving them on the other hand.
  • the invention has for its object to provide a packaging of the type mentioned, in which there is a secure locking of the two bottom wall sections together.
  • the tab is inserted into the first recess from below, with an opening remaining from the punched-out area of the tab.
  • the flap is then folded in and its free part is inserted through the opening and the second recess where it hooks.
  • An advantageous further embodiment of the invention also lies in the fact that the two fold lines of the flap run parallel to the free outer edge of the bottom wall section.
  • the part of the flap lying between the two fold lines is trapezoidal and tapers from the outer fold line to the inner fold line.
  • An advantageous embodiment of the invention is also that the length of the first fold line is less than or equal to the length of a substantially straight edge of the recess in the other bottom wall section.
  • the outer shape of the second part of the flap is formed by two straight sections and a convex circular section, the two straight sections running apart from the ends of the second fold line and being connected by the convex circular section .
  • an opening is formed according to the invention, from which two incisions extend laterally, two incisions also originating from the second recess of the other bottom wall section. These four incisions are intended to allow passage of the second part of the flap.
  • the incisions enclose an angle with the second fold line dividing the flap.
  • the second recess has a length that corresponds approximately to the length of the second fold line.
  • An advantageous embodiment of the invention is also that the distance between the substantially straight outer edge of the first recess and the portion of the second recess with the greatest longitudinal extent is approximately equal to the distance between the two fold lines of the flap.
  • Another advantageous embodiment of the invention is also that the second recess narrows towards its two ends.
  • At least one tongue is formed on the outer edge of the bottom wall section facing away from the rag, which in the erected state of the packaging engages behind an edge of this opening formed when the rag is punched out.
  • a further advantageous embodiment of the invention is characterized in that the distance of the outer edge from the edge of the first recess facing it corresponds approximately to the total length of the flap.
  • two outwardly directed hook-shaped projections are formed on the tab, the distance from the fold line dividing the tab corresponds to approximately twice the material thickness of the blank.
  • a cardboard blank 100 which has a top wall 110 with side walls 120 and 130 articulated thereon via two folding lines 112 and 113.
  • a bottom wall section 140a is articulated on the side wall 120 via a further folding line 124 and a second bottom wall section 140b is hinged on the side wall 130 via a folding line 134.
  • the two folding lines 124 and 134 are interrupted by U-shaped cutting lines 150, through which openings are created when the blank is erected, into which the objects to be packaged, not shown, engage with their lower edge section and thus experience a hold.
  • Two tabs 200 are punched out of the bottom wall section 140b and consist of two sections 200a and 200b, are hinged to the bottom wall section via a folding line 202 and are divided via a folding line 206.
  • the part 200a of the flap which is directly hinged to the bottom wall section has a trapezoidal configuration and tapers from the articulation folding line 202 to the dividing folding line 206.
  • Two straight sections 204c and 204d adjoin this part, which run outwards and in pass over a convex portion 204e.
  • two incisions 208a and 208b extend from the cutting line 204 forming the flap 200 and extend away from the flap.
  • two larger recesses 220 and two smaller recesses 240 are arranged one behind the other, which are used for inserting and locking the tabs.
  • the recess 220 is delimited by a cutting line 222 which has a substantially straight edge 222a and a curved edge 222b.
  • the recess 24o or its cutting edge 242 has two straight sections 242a and 242b, which are delimited by two inclined sections 242c, 242d and 242e, 242f and thus taper. Two incisions 244a and 244b adjoin these tips, which allow the flap 200 to pass through.
  • the length of the recess 240 denoted by L4 corresponds approximately to the length L3 of the second fold line 206 of the flap 200. Only through the length L6 resulting from the incisions 244a and 244b, which is somewhat larger than the width L5 of the upper flap part 200b, it is possible to thread it.
  • the recess 220 has a length L2 which is at least equal to the length L1 of the flap on its articulation folding line 202, as a result of which this flap section can easily be inserted into the recess.
  • the distance L8 from the central plane A of the recess 240, which has the greatest longitudinal extent, to the straight edge 222a of the recess 220 corresponds to the distance L7 of the two fold lines 202 and 206, so that a perfect threading of the flap is made possible, as is shown in FIG. b, c will be explained.
  • the tabs 200 are first pressed outwards when the blank is erected into a package.
  • the blank is then folded over its fold lines and placed around the objects (not shown), the bottom wall section 140b coming inwards and the bottom wall section 140a coming outwards.
  • the tab 200 is then pushed through the recess 220 from the inside and the two bottom wall sections 140 a and b are placed flat on one another. Then, as shown in FIG. 4b, the flap is folded in around the fold line 206 and the free section 200b of the flap is inserted inwards through the recesses 240 and 210 and then, as can be seen in FIG. 4c, stands vertically inwards.
  • the tabs and the recesses for inserting the tabs differ only slightly from those of the exemplary embodiment described above.
  • the edge 204f of the flap facing away from the articulation fold line 202 is flattened in order to be able to receive a tongue 260 which is formed on the opposite edge 142a of the blank.
  • This tongue has two oblique boundary edges 262a and 262b, which form their pointed shape.
  • it is divided into two sections by an incision 262c, which makes it easier to push it in. It is important in this embodiment that the distance L10 of the outer edge 222a of the recess 220 to the outer edge 142a of the blank corresponds to the total length L9 of the flap.
  • the push-through and threading process of the flap does not differ in the first steps from those of the previous example, as can be seen from FIGS. 8a, b, c. Then, as shown in FIG. 8d, the tongue 260 is pressed inward through the opening 210 and then comes to lie on the inside of the bottom wall section 140b. This is clearly illustrated in FIG. 9.
