Definitions

  • the invention relates to a method for producing a cardboard container from a flat blank with a central container base, on which side walls with end flaps or corner adhesive parts and side wall flaps adjoin along the bending lines, an edge strip consisting of two parallel strips forming a flanged edge on each side wall after a bending line connects, as well as a device for this.
  • US-A-2 065 804 also shows a container in which a multiple flange edge is provided, but which has no binding to the side walls.
  • the cardboard box depending on the size of the box or the volume of the box, a certain cardboard material thickness must be used so that the box with the filled goods retains sufficient dimensional stability. If cardboard containers filled with goods lose their original shape, it is difficult to place them in a larger container for transport. In the worst case, the cardboard container bursts or tears at the edges.
  • the object of the invention was to achieve significant material savings in the production of cardboard containers by using a thin cardboard material thickness without the cardboard containers losing their dimensional stability when they are filled with goods.
  • a reduction in the weight of the material per cardboard container to 2/3 the weight of a comparable cardboard container in the previously known embodiment represents a considerable economic advantage in view of the very high number of pieces in the manufacture and consumption of the containers used especially for fruit and vegetable packaging as one-way packaging in the final price and lower environmental impact. Furthermore, the adhesive bonds are to be substantially improved and, in particular, moisture-resistant connections are to be achieved.
  • the solution to the problem is that during its manufacture the edge section first is folded over along the bending line for pre-breaking and then on the other hand an adhesive strip is applied to each side wall inwards of the bending line, and then the outer strip around an outer bending line on the inner strip and both around the inner bending line so that the outer strip lies on the adhesive strip, and then, after a subsequent conversion of the blanks into the spatial container shape, the respectively shaped containers are guided in a channel, one container being inserted into the previous container, so that a stack comprising a plurality of containers is formed in the channel and is pushed on for a period of time sufficient for the adhesive bonds to solidify.
  • the double flanged rim also stiffens the cardboard containers and is therefore more dimensionally stable.
  • the production is relatively simple, but the cut with a double folded edge strip is bulky, so that the cardboard container is longer must be kept in a shape until the adhesive connections are sufficiently firm. This applies both to the outside and to the inside of flared edges.
  • the invention further relates to an apparatus for performing the method.
  • the device 1 according to FIGS. 1 and 2 has at the right end a known device 2 for inserting the blanks, which are arranged lying upright on an inclined surface 3.
  • the blanks 6 according to FIG. 3 for the production of cardboard containers 7 according to FIG. 4 are processed on the device 1, which is shown in plan view in FIG. 2.
  • the blanks arranged upright on the inclined surface 3 of the station 2 are mechanically guided away individually from the front end of the stack and are gripped by a transport device, not shown and designed in the usual way, which has two revolving chains with carriers, and moved along a horizontal contact surface.
  • a double flanged edge 25 is formed on the outside.
  • the blank 6 according to FIG. 6 has a container base 8, on which two side walls 10 with end flaps 11 border along bending lines 9. Furthermore, two side wall flaps 13 adjoin the bottom surface 8 along two further bending lines 12.
  • the edge section 15 adjoining the two side walls 10 along an additional bending line 14 is further subdivided and consists of an inner strip 15a adjoining the bending line 14 and an outer strip 15b adjoining a further outer bending line 26.
  • the outer strip 15b is the same length as the side wall 10, while the longer inner strip 15a still extends over part of the two end flaps 11 attached to the side wall 10.
  • the flanged edge 25 is not only present on the two long sides 10, but in some cases also on the two narrow sides.
  • the entire edge section 15 is first folded around the bending line 14 in a processing station 30 for pre-breaking and is held down during further transport of the blank.
  • Adhesive is then applied in a processing station 31 to the side walls 10 of the blank inwards from the bending line 14, from above to the outside, because the flanged edge is to be folded outwards.
  • the outer edge strip 15b is then folded around the outer bending line 26 onto the inner edge strip 15a and both together are then folded around the inner bending line 14 onto the zone of the side wall provided with an adhesive application / and the flanged edge thus created is pressed down during the further transport of the blank along the remaining conveyor line 33 until the blank is transferred to the subsequent processing station 19, in which the blank is brought into the spatial container shape in a clocked manner.
  • This is known to be carried out by means of a stamp lifting the inside of the container bottom 8, the side walls 10 and the side wall flaps 13, of which some of which were previously provided with an adhesive application at the points to be connected, being folded around and brought together with the aid of guide elements so that the container according to FIG. 4 is formed.
  • the containers with the open side facing downward are each pushed into the previously produced container, so that a stack of cardboard containers is pushed upward with each production cycle.
  • a very long channel 20 adjoining the processing station 19 is provided, which according to FIG. 1 is in a large arc first up to a height of over 3 meters and then down again to the one at working height Table surface of a packing table 21 is brought down.
  • this channel 20 formed from bent rods the cardboard containers are held and guided on the outside in such a way that their shape cannot change. No means of transport is provided in the channel, rather the cardboard containers are moved further in the channel by the containers pushed by the processing station 19 and are removed in batches at the packing table 21.
  • the canal holds several hundred cardboard containers so that there is a firm connection at the glued points at the end of the canal.
  • the clear cross section of the channel is of course adapted to the shape of the cardboard container.
  • a cardboard container according to FIG. 6 is produced from a blank 30 according to FIG. 5, which also has a double flanged edge 25.
  • This also arises, as in the previously described exemplary embodiment, by folding an edge strip 15 consisting of the two strips 15a and 15b twice on the blank 30.
  • the cut differs from the previously described only in that it does not have any flaps formed by incisions starting from the edge has, but at all four corners with the respectively adjacent two side walls 10 and 13 integrally connected corner adhesive parts 11a, which are folded due to existing bending lines and folded over in two layers, in order to then be glued to one of the side walls.
  • the flanged edge extends into these corner adhesive areas.
