WAYS OF CARRYING OUT THE INVENTION

1 shows the cut of a folding box 10 which, when unfolded, has an octagonal peripheral contour. The blank has a total of eight side wall elements 12.1 to 12.8, which in the exemplary embodiment shown are designed as slim rectangular wall elements and are each connected to one another via side wall folding lines 14.1 to 14.7, a side wall adhesive flap 74 being formed on the last side wall folding line 14.8.

The bottom device 16 of the folding box 10 has various folding units and tabs, which will be described below. At the bottom of the first side wall element 12.1, a first corner bottom folding unit 20 is formed via a first bottom folding line 18.1, said corner corner folding unit consisting of two trapezoidal first corner bottom folding elements 22.1, 22.2, which are connected to one another via a first bottom bottom line 24 on the respective trapezoidal side edge. The first corner floor folding element 22.1 is connected to the first side wall elements 12.1 via the floor folding line 18.1. The two corner bottom folding elements 22.1, 22.2 are arranged in the form of a flat V relative to one another. The base 23 of the first corner floor fold elements 22.2 forms an angle 28 of approximately 135 ° with the first bottom fold line 18.1.

At the bottom of the fifth side wall element 12.5 a second corner bottom folding unit 30 is formed via a fifth bottom folding line 18.5, which basically has the same structure as the first corner bottom folding unit 20. Here, too, there are two second trapezoidal corner bottom folding elements 32.1, 32.2, and also the angle 38 between the base side 33 of the second corner floor folding element 32.2 and the fifth floor folding line

18.5 is approximately 135 °.

A triangular first adhesive flap 26 is integrally formed on the second side wall element 12.2 below via a second bottom fold line 18.2. On the sixth side wall element

12.6, a triangular second adhesive flap 36 is formed on a sixth bottom fold line 18.6.

The first corner base folding unit 20 and the second corner base folding unit 30 form in the unfolded state in the opposite corner region of the octagonal floor device 16.

A third, essentially trapezoidal, bottom folding unit 40 is formed on the bottom of the third side wall element 12.3 via a third bottom folding line 18.3 and consists of two first bottom folding elements 42.1, 42.2 with a common first bottom folding line 44. The contour of the first bottom folding unit 40 is designed such that in the unfolded state the first bottom folding unit 40 forms the bottom region of the octagon shape starting from the area covered by the first bottom folding unit up to the middle. The outer end line 45 of the first bottom folding element 42.2 forms an angle 49 of approximately 45 ° with the third bottom folding line 18.3. The first bottom folding unit 40 is present inclined to the left in FIG. 1. A fourth bottom folding unit 50 is formed on the fourth side wall element 12.4 below via a fourth bottom folding line 18.4, which is inclined to the right in FIG. 1 and basically has the same structure as the first bottom folding unit 40, that is to say there are two second bottom folding elements 52.1, 52.2, which are connected to one another via a common second bottom folding line 54. However, the bottom fold line 54 has a greater length than the bottom fold line 44, so that overall there is no trapezoidal circumferential contour. However, the outer end line 55 to the fourth bottom fold line 18.4 is also present at an angle 49 of approximately 45 ° in the unfolded state.

On the seventh side wall element 12.7 there is a third octagonal bottom on a seventh bottom fold line 18.7

Shaped adhesive tab 46, which consists of a first octagonal base element 46.1 or 46.2 formed on a fold line 48. The octagon circumference contour of the octagon base elements 46.1, 46.2 essentially corresponds to the octagon circumference contour of the folding box in the unfolded state.

Finally, on the eighth side wall element 12.8 at the bottom via an eighth floor fold line 18.8 is a substantially trapezoidal fourth which is inclined to the right in FIG. 1

Adhesive flap 56 integrally formed, the trapezoidal circumference on the base side having a slight incision due to the octagon contour of the first octagon base element 46.1.

Symmetrical to the first, third, fifth and seventh side wall folding lines 14.1, 14.3, 14.5, 14.7 is in the lower area an adjacent side wall elements extending recess 60 available, which makes the product inserted into the folding box 10 visible from the outside when the folding box 10 is unfolded.

An octagonal inner cover 66 is formed on the upper side of the second side wall element 12.1 via a lid folding line 72.2. An octagonal lid 62 is formed on the top of the fifth side wall element 12.5 via a lid folding line 72.5, and has an insertion flap 64 connected via a folding line 70 on every second outside. Lid flaps 68.4 and 68.6 are integrally formed on the upper side of the fourth and sixth side wall elements via lid folding lines 72.4 and 72.6, respectively. Finally, a further cover flap 68.8 is formed on the top of the eighth side wall element 12.8 via a cover folding line 72.8.

In the case of folding boxes, it is important that the manufacturer first folds them flat before transporting them to the filler of the folding box in order to keep the transport volume small. In the case of the filler itself, the folding box must then be able to be unfolded and filled in the simplest possible way.

The steps for folding the flat transport state are explained below.

First, the second octagon base element 46.2 is provided with adhesive (puncturing in FIG. 1) and folded around the fold line 48 onto the first octagon base element 46.1. Subsequently, the first and second octagonal floor elements 46.1, 46.2, which are glued to one another, are folded upward about the seventh floor folding line 18.7. Likewise, the fourth adhesive tab 56, the third Adhesive flap 36, the second base unit 50, the first base unit 40 and the first adhesive flap 26 are folded up around the respective bottom fold line 18.8, 18.6, 18.4, 18.3 and 18.4. Likewise, the first corner bottom folding unit 20 is folded upwards around the first bottom folding unit 18.1 and then the first bottom folding element 22.2 is folded onto the first bottom folding element 22.1 around the first bottom folding line 24. Correspondingly, the second bottom folding unit 30 is folded around the fifth bottom folding line 18.5 with subsequent folding of the second one

Corner floor folding element 32.2 around the second corner folding line 34 onto the corner floor folding element 32.1. In the first floor folding unit 40 and the second floor folding unit 50, after folding over the entire unit, the first floor folding element 42.2 or second floor folding element 52.2 is folded around the first floor folding line 44 or second floor folding line 54 onto the first floor folding element 42.1 or second floor folding element 52.1. This state is shown in Fig. 2. Then adhesive is applied to the first bottom folding element 42.2, the second bottom folding element 52.2 and the second corner bottom folding element 32.2 (shown in dotted lines in FIG. 2). Then the blank is folded around the fifth side wall folding line 14.5, so that an adhesive connection of the first base folding unit 40 with the fourth adhesive flap, the second base folding unit 50 with the third adhesive flap 46 (first octagon base element 46.1) and the second corner base folding unit 30 with the second adhesive flap 36 takes place.

This state is shown in Fig. 3.

Adhesive is then applied to the first corner base folding element 22.2 and to the side wall adhesive flap 74 (shown in dotted lines in FIG. 3) and the blank is cut around the first side wall folding line 14.1 folded so that the first corner base folding unit 20 is glued to the first adhesive tab 26 and the inner wall of the first side wall element 12.1 to the side wall adhesive tab 74.

The folding box is then in the flat folded transport state, which is shown in FIG. 4, the upper area of the blank being cut off in FIG. 4 for reasons of illustration. In Fig. 4, the representation is rotated by 180 ° compared to the previous Fig.

5 and 6, the partially unfolded state of the folding box in the bottom area is shown schematically in a top view and a bottom view. By exerting pressure on the first side wall folding line 14.1 and the fifth side wall folding line 14.5 (arrow D), the bottom device 16 of the folding box 10 automatically unfolds. The corner base folding unit 20 or 30 form the corner region of the octagon base and the first base folding unit 40 and the second base folding unit 50 form the central region of the octagon base.

As shown in Fig. 9, a three-layer floor structure is given in the unfolded state.

The fully unfolded bottom area is shown in FIG. 7. The geometry of the first corner base folding unit 20 or second corner base folding unit 30 is designed such that, when unfolded, the first corner base folding unit 20, viewed from below, engages under the second floor folding unit 30 and the second base folding unit 50 in certain areas. The area under the grip is shown in dotted lines in FIG. 7. Because the fold line 54 of the second bottom folding unit 50 is longer than the fold line 44 of the first bottom folding unit 40, the second bottom folding unit 50 engages under the first bottom folding unit 40 in the unfolded state.

After the folding box has been erected, it can easily be filled from above. The folding box is closed by folding the lid flaps 68.4, 68.6 and 68.8 inwards by 90 ° by their fold lines 72.4, 72.6 and 72.8, then folding the inner lid 66 inwards by 90 ° by the fold line 72.2 and then the lid 62 is folded inwards about the folding line 72.5 after the insertion flaps 64 have previously been folded over their folding line 70.
