Figure 2a is a perspective view showing how the cushioning portions 24, 26 are folded to form. Thus, in this state, the base 2 is provided with two buffers 24 , 26 arranged at opposite ends of the base 2 . The panel is schematically depicted in the illustration of FIG. 2 a as a household panel FP, a panel having a cuboid general shape that can be arranged on the base 2 between the two buffers 24 , 26 . As used herein, "slab" refers to a thin plate-shaped object such as a door, trap door, trim panel, shelf, tabletop, floor, etc., having a substantially uniform thickness and wherein the thickness of the slab is less than the length of the slab with width.

FIG. 2b is a cross-sectional view through the first buffer portion 24 viewed along the arrow II-II of FIG. 2a. In the illustrated embodiment, the carton packaging blank is made from a corrugated paperboard material comprising an outer face paperboard layer OCL, an inner face paperboard layer ICL, and a paper board arranged between the outer face paperboard layer OCL and the inner face paperboard layer ICL. Additional middle corrugated cardboard layer CCL.

As shown in FIG. 2 b , a first folding operation is performed at a first outer gable fold line 41 to make the outer gable portion 28 extending substantially vertically upward from the base portion 2 . A second folding operation is performed at the second outer gable fold line 42 to produce the gable connection portion 32 extending in the direction of the second buffer portion 26 and substantially perpendicular to the outer gable portion 28 . Thus, the gable connection 32 extends substantially parallel to the base 2 and is located at a height H1 above the base. The height H1 depends on the thickness of the panels FP to be stored in the package and can generally be in the range of 8 to 100 mm.

A third folding operation is performed at the first inner gable fold line 44 to produce the inner gable portion 30 extending substantially vertically downward from the gable connection portion 32 towards the base portion 2 . Thus, both the outer gable portion 28 and the inner gable portion 30 are substantially perpendicular to the base 2 . Moreover, the outer gable portion 28 and the inner gable portion 30 are parallel to each other, and there is a free inner distance IS between the outer gable portion 28 and the inner gable portion 30 . The size of the free inner space IS depends on how much protection the panel FP requires. Typically, the free inner spacing IS is in the range of 10 to 100 mm.

Since in the preferred embodiment the first angle α1, the second angle α2, the third angle α3 and the fourth angle α4 all have the same value, the first side edge 34 of the outer gable portion 28 will be parallel as shown in FIG. The first side edge 38 of the inner gable portion 30 (hidden in FIG. 2 a ) and the second side edge 36 of the outer gable portion 28 will be parallel to the second side edge 40 of the inner gable portion 30 .

FIG. 3 shows the next step in making a package from the packaging blank of FIG. 1 . In this step, the first long side wall 6 is folded upwards to be supported by the parallel first side edges 34 and 38 of the outer gable portion 28 and inner gable portion 30 of the respective first buffer portion 24 and second buffer portion 26, And the second long side wall 10 is folded upward to be supported by the parallel second side edges 36 and 40 of the outer gable portion 28 and inner gable portion 30 of the respective first and second buffer portions 24 , 26 . Because the angles α1 , α2 , α3 and α4 are different from 0°, the long side walls 6 , 10 will slope slightly inwards towards the base 2 as previously shown and described with reference to FIG. 1 . The gable connection 32, in addition to keeping the outer gable portion 28 and the inner gable portion 30 at a desired distance from each other, also forms a platform on which the cover portions 14, 18 can sit (as will be shown hereinafter).

Figure 4a shows the final step of forming a flat carton package 60 from the packaging blank 1 shown in Figure 1 to cover the flat plate FP. In this final step, the first cover part 14 and the second cover part 18 are folded onto the respective buffer part 24 , 26 and rest on the respective gable connection part 32 . Optionally, a strip of tape 62 may be applied to the cover portions 14 , 18 to secure them to each other and to the respective outer gable portion 28 . Alternatively, the cover portions 14, 18 may be glued to the respective gable connection portions 32, as shown in FIG. 2b. Package 60 is now ready for shipping and sales activities. The package 60 of Figure 4a has the shape of a trapezoidal prism, but may in alternative embodiments have other shapes such as the shape of a gold bar.

Figure 4b is a side view showing the end gable 64 of the package 60 of Figure 4a. As can be seen from Figure 4b, the end gables 64 have the shape of a trapezoid without right angles, and this trapezoidal shape is symmetrical about a vertical midline. Thus, the shape of the end gable 64 is similar to that of a truncated triangle. The first side edges 34 and 38 (the latter being hidden from the perspective of FIG. 4 b ) will have the above-mentioned respective first and third angles α1 and α3 with respect to the plane PV perpendicular to the base 2, wherein An angle α1 and a third angle α3 are equal to each other and both are different from 0° with respect to the plane PV. Thus, the long side walls 6 supported by the side edges 34 , 38 will not be perpendicular to the base 2 but will have a first angle α1 different from 0° with respect to the plane PV perpendicular to the base 2 . Similarly, the second side edges 36 and 40 (the latter being hidden from view in Fig. 4b) will have the above-mentioned respective second and fourth angles α2 and α4 with respect to the plane PV perpendicular to the base 2, Wherein, the second angle α2 and the fourth angle α4 are equal to each other and also equal to the first angle α1 and the third angle α3 , and both are different from 0° with respect to the plane PV. Thus, the long side walls 10 supported by the side edges 36 , 40 will not be perpendicular to the base 2 but will have a second angle α2 different from 0° with respect to the plane PV perpendicular to the base 2 . Because the long side walls 6, 10 are supported by the side edges 34, 36, 38, 40 of the outer gable portion 28 and the inner gable portion 30 (the latter is hidden in FIG. Not perpendicular to the base 2 but inclined inwardly towards the base 2, so a first side deformation zone 66 is formed between the first long side wall 6 and the plate FP and a second side deformation zone 66 is formed between the plate FP and the second long side wall 10. Side deformation zone 68.

In Fig. 4b, the groove FT in the end gable 64 formed by the central corrugated cardboard layer CCL is partially shown. As already indicated above with reference to FIG. 1 , the groove FT preferably extends in the direction of the long axis LA of the packaging blank 1 .

Figure 4c is a cross-sectional view of the first cushioning portion 24 and a portion of the package 60 when viewed from a similar perspective as the cross-sectional view of Figure 2b. In this embodiment, package 60 is held together by adhesive tape 62 . As described above with reference to FIG. 2 b , the outer gable portion 28 and the inner gable portion 30 of the first buffer portion 24 have a free inner spacing IS between them. Thus, a third deformation region as an end deformation region 70 is formed between the gable portions 28 , 30 . The gable connection portion 32 and the inner gable support portion 46 will support the outer gable portion 28 and the inner gable portion 30 and maintain them at the desired free inner spacing IS.

The end deformations 70 will protect the flat panel FP, but also under the action of high impact forces that may occur when eg the package 60 is dropped on the floor with its cushioning portion 24 first. As can be seen, both the outer gable portion 28 and the inner gable portion 30 are perpendicular to the bottom 2 . This enhances the firmness of the cushioning portion 24 and improves the firmness of the cushioning portion 24 against impact. In a preferred embodiment, the package 60 is designed so that the flat panel FP will rest against the inner gable portion 30, thereby providing further support to the flat panel FP. Thus, the beam portion 48 will further support the outer gable portion 28 and the inner gable portion 30 and thus further strengthen the end deformation region 70 .

Figure 5 shows the bumper 124 according to an alternative embodiment and seen in a cross-sectional view similar to that of Figure 2b. The buffer portion 124 includes an outer gable portion 128 , an inner gable portion 130 , a gable connection portion 132 , and an inner gable support portion 146 , all of which are similar to corresponding portions of the buffer portion 24 . However, in the embodiment of FIG. 5 , there is no beam portion. The strength of the bumper 124 is thus slightly less than that of the bumper 24, but would be sufficient for the intended packaging for low weight panels. In another alternative embodiment, the inner gable support portion 146 extends only a portion of the free inner spacing between the inner gable portion 130 and the outer gable portion 128 .

According to an alternative embodiment, the end deformation region 170 formed between the outer gable portion 128 and the inner gable portion 130 may be at least partially filled with a filler 172 to enhance the physical strength of the end deformation region 170 . This padding 172 may be, for example, paper, cardboard, foam, or the like. In the embodiment shown in FIG. 5 , the packing 172 includes strips 174 of corrugated cardboard, wherein the strips 174 have been bonded together to form the packing 172 .

Fig. 6 shows a bumper 224 according to another alternative embodiment and seen in a sectional view similar to that of Fig. 2b. The buffer portion 224 includes an outer gable portion 228 , an inner gable portion 230 , and a gable connection portion 232 , all of which are similar to corresponding portions of the buffer portion 24 . However, in the embodiment of FIG. 6 , the inner gable support 46 is absent.
