Description

The present invention relates to a one-piece blank for a cuboid folding box with the features of the preamble of claim 1 and a cuboid folding box as well as a method for producing a cuboid folding box.

It is known to use cuboid folding boxes made of cardboard for the secondary packaging of primarily packaged products, such as flexible packaging made of plastic, in particular stand-up pouches or tubular bag packaging, such as flow packs. It is desirable that this secondary packaging is also suitable for presenting the products on the sales shelf.

The cuboid of the cuboid folding box is formed by folding a blank. The blank usually has several surface segments which are separated from one another by fold lines which form the edges of the parallelepiped. A fastening tab, which forms one end of the blank, is usually glued to the edge of an opposite surface segment, resulting in four circumferential side surfaces of the cuboid. Surface segments connected to these side faces of the cuboid by fold lines form the cover and/or the bottom of the cuboid, which can be closed by folding along the fold lines. To present the goods, a top part of the folding box is conventionally removed from a bottom part, with the products remaining in the bottom part, so that the primarily packaged products do not have to be removed from the packaging by the sales staff and the customer can access the products directly. For this it is known that folding boxes Have perforations that make it possible to separate an upper part from a lower part.

However, such secondary packaging is in need of improvement, since the perforation points at which the upper part was separated from the lower part are visible to the customer on the shelf and do not represent an attractive appearance.

It is therefore the object of the present invention to specify an improved one-piece blank for a folding box made of cardboard, which makes it possible for the customer to see only the punched edges of the blank after the upper part has been separated from the lower part.

This object is achieved by a blank for a cuboid folding box having the features of claim 1 and by a cuboid folding box having the features of claim 13 and by a method for producing a folding box having the features of claim 17.

According to this, a one-piece blank for a cuboid folding box has five main surface segments lined up next to one another and separated from one another by main fold lines on the transverse sides, with a first main surface segment forming a first end of the blank and a second main surface segment adjoining the first main surface segment and a third main surface segment adjoining the second main surface segment and a fourth main area segment adjoins the third main area segment and a fifth main area segment adjoins the fourth main area segment, wherein the fifth main area segment forms a second end of the blank, and wherein the main area segments can be folded around the main folding lines, and wherein the second main area segment is attached to the longitudinal sides in each case a second side panel segment, having an edge, adjoins via a second side fold line, with a third side panel adjoining the third main panel segment on the long sides gment is connected via a third secondary fold line, the secondary fold lines being arranged perpendicularly to the main fold lines. The blank also has a first line of perforations extending across the third major panel and at least partially across the third Secondary area segments runs, wherein the third secondary area segments are each divided into two areas by the first perforation line, wherein a first area is an area adjoining the second additional area segment and a second area is an area adjoining the fourth additional area segment, and wherein the shape of the second additional area segments and the course of the first perforation line is selected in such a way that, in the folded state, the second side surface segments completely protrude beyond the first perforation line in the region of the third side surface segments. When the folding box is folded, the first perforation line always lies below the edge of the second side surface segments, so that if the perforation line detaches, the resulting perforation edge is not visible to the customer in a side view of the sides formed by the second side surface segments. The term “overhangs” is understood to mean that a tear-off edge occurring at the separation point defined by the perforation line is covered.

In a preferred embodiment, a second secondary fold line and a second main fold line separating the second main panel segment from the third main panel segment form an intersection. x is the distance from a point on the second minor fold line to the intersection, where the height h of the second minor panel is a function of x and the height h is the distance from the second minor fold line to the edge of the adjacent second minor panel at point x. The width b of the third secondary surface segment, which is on the same side as the second secondary surface segment with respect to the longitudinal axis of the blank, in the first area is in each case a function of y, with the width b being defined as the distance from a straight-line extension of the second main folding line to the perforation line and y is the distance from a point on the straight extension of the second major fold line to the intersection point,
where the following relationship applies: $$\mathrm{if}\mathrm{y}=\mathrm{x},\mathrm{then}\mathrm{b}\left(\mathrm{y}\right)<=0.98*\mathrm{H}\left(\mathrm{x}\right).$$

It can thereby be ensured that the edge of the second secondary surface segments widens the first perforation line in the folded state towered enough.

It is also preferred that b(y)>=0.30 ^* h(x), in particular b(y)>=0.50 ^* h(x).

It is advantageous if the two second secondary surface segments are the same, and in particular if the entire blank is axisymmetric to a longitudinal axis.

The blank is preferably made of cardboard, in particular corrugated cardboard. The cardboard advantageously has a cardboard thickness of <8 mm.

Preferably, the first line of perforations runs parallel to the main fold lines. It is also possible for the first line of perforations to take any form, e.g. B. a curve or a parabola.

In order to simplify detachment when the folded box is in the folded state, a first incision preferably follows the first perforation line in the region of the third main surface segment.

It is also advantageous if the fifth main area segment has an edge, an adhesive area and a second perforation line at least partially surrounding the adhesive area, and the first main area segment has an edge, the course of the second perforation line and the edge of the first main area segment being chosen such that in the folded state, the first main surface segment completely projects beyond the second perforation line. When the folding box is folded, the second perforation line is always below the edge of the first main surface segment, so that if the perforation line detaches, the resulting perforation edge is not visible to the customer in a front view of the front side formed by the first main surface segment.

The second perforation line preferably runs on the sides of the adhesive area that are remote from the edge. The second line of perforations may be straight and parallel to the main fold lines above the glue area. However, the second perforation line can also be configured differently. You only have to run on the side of the adhesive area that is far from the edge, so that it cannot be torn off and an associated detachment of an upper part from a lower part of the folding box formed by the blank is possible.

Fourth secondary surface segments preferably adjoin the longitudinal sides of the fourth main surface segment, which have a shape corresponding to the second secondary surface segments, such that when the cuboid folding box is folded, the second and fourth secondary surface segments do not have an overlapping area. As a result, the upper part can be separated particularly easily from the lower part of the folding box along the first perforation line.

It is preferred if the third secondary surface segments are divided into two separate areas by the first perforation line, with the third secondary surface segments each having an incision at their edges, which adjoins the ends of the first perforation line. The cuts shorten the first line of perforations, making the tear-off process easier.

The distance between the incision and the third secondary fold line is preferably in a range between 20% and 60% of the distance between the third secondary fold line and the part of the edge of the third secondary surface segment running parallel thereto.

The shape of the incision is preferably adapted to the course of the edge of the second secondary surface segment.

The one-piece blank is preferably dimensioned such that the first and third main panel segments have a distance between the adjacent main fold lines of 50 to 700 mm.

The one-piece blank is preferably dimensioned such that the first and third main panel segments have a width along the main fold lines which is in a range between 60 and 400 mm.

The one-piece blank is preferably dimensioned such that the third main panel segment has a distance between the adjacent main fold lines of 40 to 300 mm.

Furthermore, a cuboid folding box is formed from a one-piece blank folded along the main fold lines and secondary fold lines as described above. Preferably, the third ancillary surface segments are bonded with their outsides to the insides of the second and fourth ancillary surface segments. Having the tabs on the inside results in an improved look.

Preferably, the second and fourth secondary surface segments each have tabs on the outer transverse sides, which are glued with their outer sides to the corresponding inner side of the first main surface segment and the fifth main surface segment. However, it can also be provided that the tabs of the fourth secondary surface segment are glued to the outside of the fifth main surface segment, since this is in the tear-off area and therefore does not impair the appearance.

It is advantageous if the fifth main surface segment forms a second tab, the outside of which is glued in the adhesive area to the inside of the first main surface segment or the insides of the third tabs adjoining the second secondary surface segment to secure the cover. The fifth main surface segment can then be separated from the first main surface segment along the second perforation line.

In a preferred embodiment, the two perforation lines enable the upper part of the folding box to be separated from the lower part, with the resulting tear-off edges being covered by the first main surface segment and the second secondary surface segments in the front view and in the side views of the folding box.

The cuboid folding box preferably accommodates primarily packaged products, which are arranged in such a way that they can be removed from the lower part via the front of the folding box, which is formed by the first main surface segment. The first main surface segment preferably has a maximum width (maximum height of the front of the lower part) in a removal area that is smaller than the minimum width of the first area of the third main surface segment (minimum height of the rear of the lower part), so it can be ensured that the primarily packaged products can rest against the back and can be easily removed from the front.

figure 1 shows an exemplary blank 1 of a cuboid folding box with a multiplicity of surface segments 2 . The surface segments 2 are separated from one another by fold lines 3 . Five main surface segments 40,41,42,43,44 are provided, which adjoin one another on the transverse sides and are folded at an angle of 90° to one another at main fold lines 45,46,47,48. The main surface segments 40,41,42,43,44 form a front wall, a rear wall, a lid and a base of the cuboid folding box. The first major panel segment 40 is a first flap 400 which is part of the front wall and forms a front view of the folded carton. A first Major fold lines 45 separate the first major panel segment 40 from the adjoining second major panel segment 41 which forms the bottom. A second main fold line 46 separates the second main surface segment 41 from the adjoining third main surface segment 42, which forms a rear wall of the folding box. In turn, the third main surface segment 42 is followed by a fourth main surface segment 43 which is separated by a third main fold line 47 . The fourth main surface segment 43 forms the cover. The sizes of the second and fourth main surface segment are identical except for one deduction due to the cardboard thickness of the flaps. The fourth major panel segment 43 is connected by a fifth major panel segment 44 via a fourth major fold line 48 . The fourth main surface segment 43 is also part of the front wall and has a second flap 430 which, when the folding box is in the folded state, is located behind the first flap 400 on the inside. The second tab 430 can be glued directly behind the first tab 400, or connected indirectly to the first tab 400 by being glued to the inside of side surfaces, as will be described later. In both variants, the first and second tabs 400, 430 are firmly connected to one another by means of an adhesive. There is no need for adhesive to secure the lid. The second, third and fourth main surface segment 41,42,43 are followed on both sides on the long sides by secondary surface segments 49,50,51 via secondary fold lines 52,53,54, which are perpendicular to the main fold lines 45,46,47,48. The secondary surface segments 49,50,51 form the side walls. The secondary surface segments 49, 50, 51 lying opposite one another in relation to the main surface segments are each of identical design. Second secondary surface segments 49 adjoin the second main surface segment 41 . The two second secondary surface segments 49 each have a linearly beveled edge 490, the height of the second secondary surface segments 49 increasing in the direction of the third main surface segment 42 and having a constant height at the end in an end region 491. The edge 490 can also have a curved shape, for example. The end area 491 extends over approximately 20% of the width of the second main surface segment 41. The second secondary surface segments 49 can but also have other edge shapes. A third flap 492 extends from each of the two second secondary surface segments 49 and is formed by an extension of the first main fold line 45 in each case. The third tabs 492 are thus lateral to the first major sheet segment 40 but have no direct connection thereto. In the folded state of the folding box, the two third flaps 492 lie behind the first flap 400 and are glued to it. Depending on how the second tab 430 is formed, it can be provided that the second tab 430, as mentioned above, is not directly bonded to the first tab 400, but only indirectly via the third tabs 492. The first tab 400 and the third tabs 492 are dimensioned and designed in such a way that the customer only sees the first tab 400 as a front view and the third tabs 492 behind it, out of sight, disappear. Third secondary surface segments 50 adjoin the third main surface segment 42 laterally by means of third secondary fold lines 53 . The third subsidiary surface segments 50 have no direct connection to the second subsidiary surface segments 49. The third subsidiary surface segments 50 each form a fourth flap 500 which is glued to the outside on the inside of the associated side wall. The fourth tabs 500 each have a straight edge that runs parallel to the secondary fold line 53 . They are divided into two areas 501, 502, with a first area 501 being an area adjoining the second secondary area segment 49, which extends over a width of approximately 60% of the total width of the third main area segment 42 and to which a second area 502 is adjoining over a width of about 40% connects. The two areas 501, 502 are each formed by an incision 503 on the edge of the third secondary surface segment 50, which extends in an area parallel to the main fold lines 45,46,47,48, and a first perforation line 504 connecting the incisions 503. The height of the cuts 503 is about 50% of the total height of the third minor surface segment 50 in the area with the parallel edge. The incisions 503 are triangular in shape with the acute angle formed inside. The first perforation line 504 thus runs across the two third secondary surface segments 50 and the third main surface segment 42 and also separates the third main surface segment 42 into a first region 420 and a second area 421 analogous to the third secondary surface segments 50 . However, the incisions 503 corresponding to the design of the second and fourth secondary surfaces can also be dispensed with. A semicircular incision 55 is provided in the middle of the first perforation line 504, in the middle of the third main surface segment 42, and can be pressed into an interior space of the folding box around the first perforation line. This incision 55 points towards the fourth main surface segment and is intended to engage in the rear wall of the folded carton. The first line of perforations 504 defines a top and a bottom of the folding box. The lower part is formed by the first and second main surface segments 40, 41 and the first area of the third main surface segment 420 and the second secondary surface segments 49 and the first area of the third secondary surface segments 501 and the third tabs 492. When the folding box is in the folded state, the upper part can be separated from the lower part by means of the first perforation line 504 in the rear area for product presentation.

Fourth secondary surface segments 51 adjoin the fourth main surface segment laterally via fourth secondary fold lines 54 . The fourth secondary surface segments 51 have no direct connection to the third secondary surface segments 50. The fourth secondary surface segments 51 have a constant height in a first region 510, which makes up about 20% of the width of the fourth main surface segment 43. This is followed by a linearly beveled edge 511 , the height of the fourth secondary surface segments 51 increasing in the direction of the fourth main surface segment 44 . The shape of the fourth secondary surface segments 51 corresponds to the shape of the second secondary surface segments 49 which together form the side walls. It can be provided that the two secondary surface segments 49, 51 overlap or are spaced apart by a gap at the edge. The edges can be adapted to the desired lateral appearance when presenting goods. In the illustrated embodiment, the fourth secondary surface segments 51 have semi-circular incisions 512 arranged approximately centrally in terms of width, which can be bent around a fold line and thereby merge into the areas formed by the folding box Allow the interior to bend and take on a supporting function when loading the folding box. A fifth flap 513 , which is formed by an extension of the fourth main fold line 48 , extends from each of the two fourth secondary surface segments 51 . The fifth tabs 513 are thus lateral to the fifth major sheet segment 44 but have no direct connection thereto. When the folding box is in the folded state, the two fifth flaps 513 lie on the inside behind the second flap 430 and are glued to it. In order to separate the upper part, consisting of the second area of the third main surface segment 421, the second areas of the third secondary surface segments 502, as well as the fourth and fifth main surface segments 43, 44 and the fourth secondary surface segments 51 including the fifth tabs 513, from the lower part, second tab 430, a second line of perforations 56 is formed around the adhesive area 57. To present the goods on the shelf, the second flap 430 is pressed inwards and separated at the second perforation line 56 . The adhesive area 57 and the second perforation line 56 are arranged in such a way that they lie below the edge of the first flap 400, the front view, in this area and are covered by the first main surface segment. The tear-off edge formed by the separation on the second flap 430 is therefore not visible to the viewer of the folding box standing on the shelf in the front view. In the next step, the upper part is separated from the lower part in the area of the back wall by engaging in the central incision 55 and detaching along the first perforation line 504 . Then the upper part can be completely removed from the lower part. In the folded state of the folding box, the first perforation line 504 lies below the edge of the second secondary surface segment 49 in the end area 491, so that the first tear-off edge in the end area 491 formed when the folding box is separated projects upwards from the edge of the side walls and the tear-off edge lies behind the edge of the side walls disappears and is hidden by the side walls.

A preferred embodiment of the second and third secondary surface segments and the first perforation line is described below with reference to FIG figure 1 described.

The second secondary fold line 52 and the second main fold line 46 separating the second main panel segment 41 from the third main panel segment 42 form an intersection. x is the distance from a point on the second side fold line to the intersection. The height h of the second minor panel 49 is a function of x, and the height h is the distance from the second minor fold line 52 to the edge of the second minor panel 49 at point x. The width b of the third secondary panel segment 50 in the first area 501 is a function of y, where the width b is defined as the distance from a straight-line extension of the second main fold line 46 to the perforation line 504 and y is the distance of a point on the straight-line extension of the second major fold line 46 to the point of intersection. The following relationship then preferably applies:
if y=x, then b(y)<=0.98 ^∗ h(x).

It can thus be ensured that the secondary surface segments always cover the perforation line along the edge of the second secondary surface segments.

The folding process of the cuboid folding box is based on the Figures 2 to 4 explained. figure 2 shows an entry of blanks 1 stacked on top of one another into an erector. A blank remover 58 grips the third major panel segment 42 from above and folds the third minor panel segments inward along the third minor fold lines 53 . As in figure 3 shown, adhesive is applied to the inner sides of the fourth secondary surface segments 51 by means of glue heads 59 . The same happens with the insides of the second side surface segments 49. However, the adhesive can also be applied to the opposite side, the third side surface element 50. Thereafter, the blank remover 58 is lowered and by inserting the third main panel segment 42 into a mold shell 59, the second and fourth secondary panel segments 49,51 and the second and fourth main panel segments 41,43 are folded inward about the corresponding fold lines. The adhesive connects the insides of the second and fourth side surface segments 51,49 with the outsides of third side surface segments 50. Then the shell molds 59 are removed and the erected folding box is transported out of the erector. The folding box is open at the top. The front is on top and the front wall is therefore not yet formed. In this state, the folding box is automatically loaded with primarily packaged products, such as flexible plastic packaging, in particular stand-up pouches or flow packs, as in figure 4 shown. The products 60 are stacked in the folding box. The folding box is then closed in the front area and the front wall is formed. For this purpose, the third and fifth tabs 492, 513 are folded in first. In the next step, the fifth main surface segment 44 or the second flap 430 is folded in about the fourth main folding line 48 and in a last step the first flap 400 is folded inwards about the first main folding line 45 . As already described above, the first flap 400 and the second flap 430 are firmly connected to one another.
