Description

[0001] The invention relates to a sorting insert for outer packaging, in particular a folding box or an outer packaging tubular film, which is formed from a flat cardboard blank (I, II, III), wherein a base and two longitudinal side walls are delimited by folding folds which are preferably arranged parallel and spaced from one another, wherein the longitudinal side walls (2) have a second end section (4) at both ends, on either side of a first base-side end section (3), wherein the first and second end sections (3, 4) complement one another at an angle to form two oppositely arranged transverse side walls and are connected to one another in a form-fitting manner.

[0002] In the packaging sector, for example, in the confectionery sector, sorting inserts are used to protect the products and, if necessary, position them at a distance from each other to prevent mutual damage. Such sorting inserts are usually made of plastic. Although various cardboard solutions have been found in the past (see, for example, DE 9316616 U1, E 9200107 U, DE 20 2020 103 119 U1, DE 197 47 420 A1, JP 2021 95 183 A), these have not been widely adopted. One reason for this is the higher production costs compared to plastic.

[0003] This is where the present invention comes in. The invention is based on the object of providing a cardboard sorting insert that is formed from a flat cardboard blank and can be manufactured more cost-effectively.

[0004] The invention provides a cardboard sorting insert which is formed from a flat cardboard blank and is inexpensive to produce. Because the longitudinal side walls have a second end section on either side of a first bottom end section at each end, wherein the first and second end sections complement each other at an angle to form two oppositely arranged transverse side walls and are positively connected to each other, production is possible solely through a folding process. Advantageously, the longitudinal side walls are attached to the bottom at an angle of greater than 90°. The sorting insert is preferably folded from the flat cardboard blank without the use of adhesive.

[0005] Here, the inner surfaces of the two transverse side walls are essentially formed by the first end sections, with the second end sections abutting on the outside of one of the first end sections. The second end sections have a tab on their side facing the base, which each engages in an inwardly folded recess arranged between a first end section and the base. This achieves a stable, form-fitting connection by simply folding the tab into the recess. The stability of the form-fitting connection can be significantly increased by providing the tab with at least one undercut that engages behind the first end section in the region of the recess.

[0006] The bottom-side displays serve two purposes: Firstly, they secure the tabs of the second end sections by simply folding them in, thus securely connecting them to the first end section. Secondly, they serve as stacking lugs, on which a stacked sorting insert rests, making it easy to remove.

[0007] In another embodiment of the invention, the inner surfaces of the two transverse side walls are essentially formed by the second end sections, with the first end sections abutting the outside of the second end sections. At least one first end section has two tabs at its end, each of which engages at an inward angle into a second end section. The stability of the positive connection can be significantly increased by providing the tab with at least one undercut that engages behind the respective engagement.

[0008] In a further embodiment of the invention, at least one first end section has only one tab at its end, which engages around the two second end sections adjacent to it. Because both second end sections adjacent to the first end section are encompassed by the one tab of the first end section, an additional connection of the two second end sections is achieved.

[0009] Alternatively, the second end sections can each have a tab on their side facing away from the floor, which engages at an outward angle into a recess in the first end section. Here, too, a stable, positive connection is achieved by simply folding the tab into the respective recess.

[0010] In a further embodiment of the invention, at least one first end section has a tab at its end, which engages around the two adjacent second end sections. This creates a connection that engages around the second end sections, thereby increasing the stability of the side wall formed by the two second end sections.

[0011] In a further development of the invention, two inwardly folded projections are arranged between the base and the first end section, each of which engages a recess in a second end section. This further increases the stability of the fold. Furthermore, the projections form stacking lugs that improve stackability.

[0012] In one embodiment of the invention, at least one dividing web is arranged on at least one longitudinal side wall to divide the chamber into several filling chambers. Preferably, several dividing webs are arranged, positioned in pairs opposite one another or offset from one another.

[0013] In a further embodiment of the invention, the dividers are formed by L-shaped folds from a side wall and the base. This creates a delicate yet stable separation. Preferably, two oppositely arranged dividers are designed to flare conically in the direction opposite the base.

[0014] In a further embodiment of the invention, each divider is arranged in front of a recess formed in the base, merging into the respective longitudinal side wall. The recess is wider than the divider and extends beyond it on both transverse sides. This allows for unhindered engagement of a divider of one sorting insert into the recess of another sorting insert stacked within this sorting insert, preventing the dividers from interlocking with one another.

[0015] In a further development of the invention, the longitudinal side walls are tapered from the base to the base, widening conically. This further improves stackability. The dividers of two stacked sorting trays can thus rest against each other.

[0016] In one embodiment of the invention, two inwardly folded projections are provided on both transverse side walls, spaced apart from each other between these and the floor. These create steps, further increasing the stackability of the sorting insert. Multiple sorting inserts in a stack are spaced apart from each other by the steps, making them easy to remove.

[0017] In a further embodiment of the invention, the distance between the two projections of a transverse side wall is different from the distance between the two projections of the opposite transverse side wall. By stacking sorting inserts rotated 180 degrees relative to each other, the tiers can be prevented from interlocking. This prevents a tier from interfering with the tier formed by another tier.

[0018] Further developments and refinements of the invention are specified in the remaining subclaims. An embodiment of the invention is illustrated in the drawings and described in detail below. They show: Fig. 1: the schematic representation of a sorting insert; Fig. 2: the representation of the cardboard cut-out of the sorting insert from Fig. 1; Fig. 3: the schematic representation of a sorting insert in a second embodiment; Fig. 4: the representation of the cardboard cut-out of the sorting insert from Fig. 3; Fig. 5: the schematic representation of a sorting insert in a third embodiment; Fig. 6: the representation of the cardboard cut-out of the sorting insert from Fig. 5.

[0019] The sorting insert chosen as an example according to Fig. 1 is formed from a flat cardboard blank I, such as the one in Fig. 2. It comprises a base 1, on whose long sides a long side wall 2 is positioned at an angle of 110° via a first fold 11. On its two transverse sides, a first end section 3 is delimited by a second fold 12. The first end sections 3 are folded upwards in the direction of the two side walls 2 via the second folds 12. In the exemplary embodiment, the first end sections 3 are essentially rectangular.

[0020] Second end sections 4 are provided at both ends of the longitudinal side walls 2, each defined by a third fold 21, over which they are folded toward the respective opposite side wall 2 and each abut against a first end section 3 on the outside. In the exemplary embodiment, the second end sections 4 are essentially trapezoidal in shape. The first end sections form the inner surfaces of the side walls of the sorting insert.

[0021] Connecting the base 1 to a respective first end section 3, there are two inwardly folded projections 5 spaced apart from one another. The two second end sections 4, each adjacent to a first end section 3, each have a tab 41 on the base side with an undercut, which is folded into a projection 5, engaging behind the corresponding first end section 3, whereby the second end sections 4 are connected in a form-fitting manner and each to a first end section 3. The projections 5 are formed in the cardboard blank in Fig. 2 are each delimited by two cuts 51 arranged parallel to one another and are folded inwards at right angles via a second fold 12 during the folding process for producing the sorting insert.

[0022] Rectangular recesses 22 are arranged opposite each other and spaced apart from each other in the longitudinal side walls 2, extending into the base 1. Connecting the narrow sides of each recess 22 is a dividing web 6 in the form of an inwardly folded, L-shaped projection. Two oppositely arranged dividing webs 6 are designed to extend conically upwards.

[0023] The recesses 22 are in the cardboard blank I in Fig. 2 are each formed by two narrow rectangular slots 221 arranged parallel to one another, between which the separating webs 6 are delimited, which are flared inwards in an L-shape via fourth folds 61 during the folding process for producing the sorting insert.

[0024] When sorting according to the Fig. In the embodiment shown in Figure 3, the first end sections 3 are folded behind the second end sections 4, which form the inner surfaces of the side walls of the sorting insert. On the upper side facing away from the base 1, two tabs 31 are arranged at a distance from one another on the first end section 3.

[0025] In this exemplary embodiment, the second end sections 4 are essentially rectangular and almost abut one another. On their upper side facing away from the base 1, the second end sections 4 each have an undercut engagement 42, into which a tab 32 of the first end section 3, also having an undercut, engages.

[0026] Between the base and the two first end sections, two inwardly folded projections 5 are arranged, each of which engages in a recess 43 in the base provided in a second end section. In the exemplary embodiment, the distances between the two projections 5 on the opposite transverse sides of the base 1 are selected to be different. The carton blank II for this sorting insert is shown in Fig. 4 shown.

[0027] When sorting according to the Fig. In the further embodiment shown in Figure 5, a wide, undercut flap 32 is arranged on each of the first end sections 3 positioned behind each of the two second end sections 4 arranged on a transverse side, said flap being folded over both second end sections 4. For this purpose, the two second end sections 4 of each of a transverse side have a common engagement 44 extending over both end sections 4, which is provided with an undercut on both sides and in which the wide flap 32 of the first end section 3 engages. The carton blank III for this sorting insert is shown in Fig. 6 shown.
