Definitions

  • the invention relates to a folding box with a bottom, with side walls and with a lid.
  • Folding boxes of this type are used for the storage and transport of goods of all kinds, in particular also of fruit, for example bananas.
  • the folding boxes used for this purpose today consist of a lower part with a bottom and side walls, over which an upper part with a lid and side walls can be placed (so-called slip box). So that the known folding boxes can carry the necessary weights, the flaps of the folding box must be clamped together. They are therefore not to be laid flat in the empty state without considerable effort. There is also a risk of injury from the brackets.
  • a folding box with the features of the preamble of claim 1 is described in US-A-4,406,380.
  • This folding box has no bottom.
  • There the inner, upper ring has double fold lines. With such double fold lines, however, it can only be achieved insufficiently that the upper ring has a smaller diameter than the lower ring.
  • the upper ring must have a smaller diameter than the lower ring, because otherwise it cannot be moved like a telescope to the lower ring. It should also be taken into account here that the fold lines must be parallel to each other due to the cut.
  • the invention is therefore based on the object of a folding box with the features of the preamble of Main claim to design so that the two part-folding boxes (upper and lower ring) can be easily moved to each other.
  • the invention is characterized in that folding lines are created in the side walls of the inner ring, each including acute angles with the folding line by means of which the side walls are articulated to one another, and which open towards the cover panels.
  • handle holes are provided in the side walls. These also make it easier to handle or move the folding boxes telescopically to each other.
  • the free cuts mentioned there can also be provided, which also make it easier for the side walls in the area of the free cuts to be bent inwards and thus can be easily folded into the outer ring.
  • corresponding free cuts can also be formed on the lower sides of the outer ring, as is the subject of the new patent claim 4.
  • the invention is characterized in that the folding box has excellent stability even without the use of clips.
  • the unfolded box can be laid flat with a handle when it is not filled, so that it then takes up little space for transport and can also be easily disposed of.
  • the folding box according to the invention is characterized overall by simple handling and low material consumption.
  • the lid is formed automatically in that the lid panels are folded down, the lid being formed by the fact that the upper and lower partial lid panels, which are connected to one another by the horizontal fold line, practically lie on top of one another and fold horizontally.
  • outer side wall panels are articulated to the free edges of the cover panels, which are articulated to one another, which extend parallel to the associated side panels and which are offset to the outside by a small amount with respect to these side panels, the side wall panels assume the function of connecting the cover panels to one another.
  • the ring of the side wall panels is formed, which can be pushed telescopically over the lower side walls of the folding box and during this movement the lid automatically folds up in the manner described above.
  • the cover panels rest against the side wall panels and the - empty - folding box can then be folded flat.
  • the bottom of the folding box is suitable for laying flat, as is known per se. This is explained in more detail below using the exemplary embodiment.
  • the pairs of grip holes on the side walls and on the side wall panels serve to carry the box (folding box).
  • the ventilation holes in the side walls or in the side wall fields are particularly important if tropical fruits are to be transported in the folding box, which is a preferred area of use for the folding box according to the invention.
  • the folding box is preferably cuboid, although folding boxes with any polygonal plan can be produced according to the principle described, in particular if the plan is symmetrical.
  • the telescopic movement is facilitated if the side walls have free cuts in their upper areas so that they can be bent slightly inwards, so that the side wall panels located above can carry out the telescopic movement particularly easily.
  • FIG. 4 shows that the folding box has a bottom 1 and side walls 2.
  • a lower partial cover panel 4 is articulated to the upper edges of the side walls via a fold line 3 and an upper partial cover panel 6 to this via a fold line 5.
  • 7 additional side lines 8 are attached to the upper edges of the upper partial cover panels 6 articulated.
  • the lower edges of the side wall panels 8 are indicated at item 9.
  • FIG. 1 to 4 show an intermediate layer of the design of the cover, from which it is clear that the partial cover fields 4, 6 are folded onto one another in a horizontal position when the ring of the outer side wall panels 8 is pushed down in the direction of arrow 10. In this fully unfolded position, grip holes 11 in side walls 2 and in outer side wall panels 8 are also aligned.
  • the V-profile of the partial cover panels 4 + 6 does not interfere with one another when the cover is formed, they each have triangular cutouts 12 on one side, which can be seen in FIG. 5.
  • the bottom can also be folded flat and for this purpose folding lines 14 are provided in the bottom flaps 13, as is known per se.
  • the fold lines 14 separate a partial flap 15 and this is glued to the respectively adjacent bottom flap 16.
  • ventilation holes 18 can be formed in the side walls 2 and in the outer side wall panels 8.
  • Fig. 5 shows only half the benefit of the blank, must these are supplemented by an identical blank and the two blanks are glued to one another via adhesive tabs 19 which are hinged to the side wall 2 or to the side wall panel 8 via fold lines 20. Additional folding lines 21, 22, 23 can also be created in the side wall 2, which include an acute angle with the folding line 20.
  • the outer side wall panels 8 are articulated to one another via folding lines 24 and thus form a ring.
  • the floor 1 does not fill the entire floor area.
  • the bottom flaps 13, 16 this can be done if desired.
  • the cover for which purpose the cover fields 4 and 6 must be enlarged accordingly.
