Description

The present invention relates to a folding box. Such folding boxes are usually made of solid or corrugated cardboard. These folding boxes are used for the transport of goods and for the presentation of these goods on the shelves of the trade. Usually, these folding boxes are delivered to the user in the unfolded state, where they are unfolded to form a cardboard box, a tray or the like. There is a need here for the folding process to be as efficient as possible.

From the EP 3 194 281 B1 a stackable folding box is known. The load is transferred there through reinforced longitudinal edge sections over the side walls.

The object of the invention is therefore to create a folding box which meets all the requirements of the packaging industry, logistics and trade.

This object is achieved by the combination of features of claims 1 and 2. The claims referring back contain partly advantageous and partly inventive developments of this invention.

The inventive folding box according to independent claim 1 consists of a one-piece blank. This blank consists of side walls that are adjacent to one another and are fixed to one another and are separated from one another by folding lines. Bottom flaps or locking tabs are formed on the lower edges of the side walls. These bottom flaps and closure flaps are pivotably mounted on the side walls with fold lines running in the longitudinal direction.

Folding flaps or stacking corners are also formed on the upper edges of the side walls. These folding flaps and stacking corners are pivotably mounted on the side walls with fold lines running in the longitudinal direction.

The folding lines each run parallel and in pairs offset by one material thickness each such that the folding lines of the closure flaps are offset outward and the folding lines of the folding flaps that lie on the side walls are offset inward. In this context, material thickness means the wall thickness of a side wall of the folding box.

The advantage of the invention is the fact that, due to glued folding flaps on the top of the folding box, no open waves are visible and the folding box has a high torsional strength. The folding box thus meets essential retail requirements.

The fact that the side walls are connected to the blank is also advantageous. By connecting the two side walls at the edge, for example by gluing using an adhesive flap, a closed box body is created. Since the bottom flaps and the locking tabs do not have to be pivoted for this purpose, it is possible to load the folding box from the bottom and to close the bottom only after loading. A lid can also be inserted into the folding box from the bottom. The bottom flaps preferably form a closed bottom.

The blank of the folding box consists of side walls that are adjacent to one another and are fixed to one another and are separated from one another by fold lines, for example grooves. On the lower edges of the side walls, bottom flaps and locking tabs are formed alternately. At least one contact edge is formed on each closure flap. This contact edge runs parallel to the fold line between a closure flap or a bottom flap and its associated side wall.

Furthermore, folding flaps and stacking corners are formed on the upper edges of the side walls. The stacking corners of adjacent side walls are folded onto one another and glued together to form support corners. The carrying corners ensure that the load is transferred via the outer edges of the folding box formed between two side walls when the folding boxes are stacked on top of one another. The load transfer via the outer edges formed by vertical fold lines causes a high inherent stability of the folding boxes according to the invention on the one hand and a high stacking stability of a folding box stack formed from stacked folding boxes on the other hand. The vertical fold lines are directly connected to the bottom flaps. Furthermore, the bottom flaps are not trimmed. Both measures increase the inherent stability of the folding boxes according to the invention and thus also their stacking stability.

The ends of the contact edges of the closure flaps for the bottom flaps run in such a way that they leave open spaces on the underside of the folding box. These open spaces are sub-areas of the bottom flaps. With these open spaces, a folding box rests on the carrying corners of a folding box underneath and thus prevents the folding boxes from slipping during transport. The free areas can be adapted to the geometry of the support corners and then form a fit with the support corners. However, geometrically different open spaces and support corners can also be combined with one another.

In order to design the folding box as shelf packaging, a discharge opening is formed in a side wall in a preferred embodiment. A side wall with a molded-on bottom flap is preferably selected for this.

This side wall with the discharge opening can be embedded between side walls with front edges running obliquely to the rear. It is also conceivable to present goods in a folding box in such a way that they protrude beyond the top edge of the box. In order to be able to stack such crates or folding boxes and be able to transport them in a stack, the folding box is in a base part, the actual one Rise, and a hood split in two. The hood can either be inserted into the base part so that the side surfaces of the hood are placed with their end faces on the inner surfaces of the bottom flaps, or the hood can be placed with its side surfaces in a suitable manner on the side walls of the base part. The stacking corners that are then missing on the base part and act as carrying corners are arranged on the top surface of the hood so that the folding box composed of the base part and hood can rest with its free areas in the area of the bottom flaps on the carrying corners of a folding box according to the invention arranged below. In this way, both folding box versions can be stacked on top of one another as required.

The version with the base part and hood differs from the basic version according to claim 1 only in that the stacking corners that act as carrying corners are at least partially arranged on the hood. The structure of the base part otherwise corresponds to the structure of the folding box according to claim 1 with all its advantages. In this embodiment, the carrying corners ensure that the load is transferred via the outer edges of the hood formed between two side surfaces or between one side surface and a pivoting wing mounted on it when folding boxes are stacked on top of one another. The load transfer via the outer edges formed by vertical fold lines causes a high inherent stability of the folding boxes according to the invention on the one hand and a high stacking stability of a folding box stack formed from stacked folding boxes on the other hand.

In both versions of the folding box, the stacking corners, which act as carrying corners, only have the material thickness of one wall thickness and therefore only protrude slightly upwards. This makes it possible, during order picking, to stack even folding boxes without open spaces on the bottom, that is to say folding boxes with a smooth bottom, on the folding boxes according to the invention. The smooth bottom then rests on the top of the folding box according to the invention due to the dead weight of the folding box.

To form a recess, the front contact edges of the closure flaps for the bottom flaps run in a preferred embodiment at a certain distance from the fold line. As a result of this configuration, when two folding boxes are stacked on top of one another, the contact edges of the upper folding box abut against the inner sides of the upper edges of the side walls of the folding box below. In this way, both folding boxes form an additional form fit or fit with one another and can no longer slip against one another. The elimination of openings or recesses in the floor itself is advantageous, which increases the stability of the floor.

The distance between the contact edge and the associated fold line preferably forms a recess which corresponds to the wall thickness of the side wall of the folding box, that is to say to its material thickness. Since the folding boxes have pivotable folding flaps on the upper edges of their side walls to stabilize the upper edges and to cover the open wave of the corrugated cardboard material on the inside of the side walls, the recess then preferably corresponds to twice the wall thickness of the folding box or the side walls. In this way, the underside of a folding box engages with two opposing contact edges according to the lock-key principle in the upper opening of the folding box below. In addition, it is advantageous to design a flap fold line as a double counter-grooving

Finally, it is possible to form or pivot tabs on one or more side walls, which are pivoted into the interior of the folding box when the folding box is set up in order to create a presentation area for the goods to be offered above the bottom flaps. This presentation area can rise towards a side wall of the folding box in the manner of a theater stage, for example from the unloading opening to the rear wall. One or more contact surfaces can also be created for goods to be specially placed. Finally, it is also possible to form recesses that are adapted to the external geometry of the goods to be presented in these tabs, for example circular recesses for glasses or yogurt cups. These flaps make it possible to optimally adapt the presentation surface of the folding box to any different goods.

To form a floor step, for example, a narrow spacer flap is adapted to the edge of a floor flap and a wider base flap is in turn adapted to the spacer flap. The spacer flap and the bottom flap are pivotably mounted on the bottom flap or on one another via fold lines. The bottom flap is itself fixed to the associated side wall by means of an adhesive flap. When erecting the floor step, there is a risk that the spacer bracket and the floor bracket tilt against each other. One or more openings are formed in the bottom flap in order to be able to reach through the bottom flap to the bottom flap and to erect the floor step without tension. The floor step can be designed as a continuous surface or as a compartment adapted to the transported goods.

To form a presentation surface sloping down from the rear side wall towards the discharge opening, it is proposed to link a spacer tab to each of the two bottom flaps and a wide bottom tab to the spacer tab. The spacer tabs have different widths in the transverse direction of the blank. The wide bottom flaps bridge the bottom flaps and interlock with their front sides so that a sloping presentation surface is created.

To form a contact surface, a bottom flap is extended so that the contact surface can be folded out and, when the folded box is unfolded, protrudes into the interior of the folded box and is preferably fixed on the inside of a side wall.

Any other configurations of the presentation area are conceivable.

All identical parts are provided with identical reference numbers. In order to avoid unnecessary repetition, only their deviations from the original exemplary embodiment are described in the case of modified exemplary embodiments.

Fig. 1 shows a one-piece blank for a folding box designed as a tray. In the longitudinal direction 1 - based on the unfolded blank - a short side wall 2, a long side wall 3 with a loading and unloading opening 4, a further short side wall 2 and a long side wall 3 are arranged side by side. The side walls 2, 3 are each pivotably mounted on one another and delimited from one another by fold lines 6 running in the transverse direction 5 - based on the unfolded blank. At the in Fig 1 An adhesive flap 7 is adapted to the right side wall 3. To set up the blank, the side walls 2, 3 are each pivoted by 90 ° around the fold lines 6 against each other and the adhesive flap 7 on the viewer of the Fig. 1 facing away from the left side wall 2 glued. The result is a folding box with an open top and bottom. This body can be loaded from its underside.

To complete the crate, the bottom flaps 8, which are pivotably mounted on the lower edges of the long side walls 3, are folded inwards along the fold lines 9 running in the longitudinal direction 1. To fix the bottom flaps 8, the locking tabs 10, which are pivotably mounted on the lower edges of the short side walls 2, are pivoted inward about their fold lines 9, which also run in the longitudinal direction 1, and are glued to the outer sides of the bottom flaps 8 with their central areas 11. This creates a closed floor area.

On the closure tabs 10, for their part, tab fold lines 12 running in the longitudinal direction 1 are formed. Along these tab fold lines 12, edge supports 13 mounted on the closure tab 10 can be pivoted back onto the outer sides of the closure tabs 10 facing away from the bottom flaps 8 be glued. After the pivoting back, a contact edge 14 formed on the edge carrier 13 then runs parallel to the fold line 9 at a distance.

At their upper edges, the side walls 2, 3 carry folding flaps 15 to cover the open wave of the corrugated cardboard material and to stabilize their upper edges and the crate as a whole. Furthermore, stacking corners 16 are formed in the corner regions. The stacking corners 16 of two adjacent side walls 2, 3 are placed one on top of the other in the final assembly state and either glued directly to one another ( Fig. 2 ) or a fastening leg 17, which is pivotably mounted on the stacking corners, is pivoted around the stacking corners 16 lying one above the other in order to be glued to their underside ( Fig. 1 ). The difference between the exemplary embodiments in Fig. 1 and Fig. 2 is therefore that according to Fig. 1 the stacking corners 16 are indirectly connected to one another by the fastening legs 17 which encompass them, while Fig. 2 shows a direct connection of the stacking corners 16, namely an adhesive bond.

In Fig. 3 the crate is shown in the fully erected and glued state. At the upper edge of the crate, all of the folding tabs 15 are pivoted about their associated folding lines 9 by 180 ° and glued to the inside of the side walls 2, 3 and so stiffen the top edge of the crate. The stacking corners 16 are also glued together.

The bottom of the crate is in Fig. 3 Shown transparently, so that not only the bottom flaps 8 but also the closure tabs 10 glued to their outer sides are visible with their details. The bottom flaps 8, which are pivoted towards one another, completely close the tray floor. The central areas 11 of the locking tabs 10 protruding far into the tray bottom in the crate longitudinal direction 25 are glued to the outer sides of the bottom flaps 8 and keep the bottom flaps 8 and thus the tray bottom closed. The edge supports 13 are pivoted through 180 ° along their tab fold lines 12 and thus form a second material layer. They are glued to the areas of the closure tab 10 that touch them. Around To form further material layers, that is to say a third or fourth etc. material layers, several edge supports 13 delimited from one another by flap drop lines 12 can be provided. These edge supports 13 are mounted on one another and are pivoted on one another and glued to one another.

In the left area of the Fig. 3 The crate shown is particularly easy to see that the contact edge 14 of the edge support 13 runs parallel to the fold line 9 and thus to the lower edge of the side wall 2. Furthermore, a distance between the lower edge of the side wall 2 and the contact edge 14 is left free. If the upper riser is in Fig. 3 When placed on the lower crate, the upper edge of this lower crate reinforced by the folding flap 15 engages in this distance between the lower edge of the side wall 2 and the contact edge 14 of the upper crate. The contact edge 14 of the closure flap 10 of the upper tray then rests on the folding flap 15 and thus on the upper edge of the lower tray. Since abutment edges 14 are present on both sides of the crates, the abutment edges 14 resting on the upper edges of the lower crates prevent the crates from slipping against one another.

In the FIGS. 1 to 3 it can be seen that the contact edges 14 are provided at their ends with bevels 18 which continuously move away from the contact edge 14. These bevels 18 are limited in their ends facing away from the contact edge 14 by stop edges 19 running at right angles to the contact edge 14. These stop edges 19 have the same function as the contact edge 14. If the upper crate in Fig. 3 placed on the lower crate, the upper edge of this lower crate reinforced by a folding flap 15 engages at a distance between the lower edge of the side wall 3 and the stop edge 19. The stop edge 19 of the closure flap 10 of the upper tray then rests against the folding flap 15 of the side wall 3 and thus again on the upper edge of the lower tray. Since stop edges 19 are formed on both sides of the edge support 13, the stop edges 19 resting on the upper edges of the lower crate prevent the crates from slipping against one another. The two contact edges 14 extending in the transverse direction of the crate 20 in the exemplary embodiment of FIG FIGS. 1 to 3 slipping of the two crates placed one on top of the other in the longitudinal direction of the crate 25 and the four stop edges 19 each running in the longitudinal direction of the crate 25, the two crates placed one on top of the other slipping in the transverse direction of the crate 20.

In addition, the bevels 18 leave between their front edges and the lower edge of the opposite side wall 2 one in the embodiment of FIG FIGS. 1 to 3 trapezoidal open area 21 free. With this open area 21, the upper tray stands on the stacking corners 16 of the lower tray. The stacking corners 16 connected to one another form support corners of the respective crates, via which the loads of the crates lying above are carried into the outer edges of the crates formed by the folding lines 6 running in the transverse direction 5. The free areas 21 can also have a different shape than the stacking corners 16.

In an advantageous embodiment, the lower edge of the side wall 2 associated with the incline 18 protrudes downward beyond the bottom flaps 8 and, together with the incline 18, forms an edge for the free area 21.

Fig. 4 shows how Fig. 2 a blank with stacking corners 16 glued directly to one another. In this exemplary embodiment, the discharge opening is made in a short side wall 2. The bottom flaps 8 are also pivotably mounted on the lower ends of the short side walls 2. The locking tabs 10 are correspondingly pivoted on the long side walls 3. Compared to the execution according to Fig. 2 are omitted in the exemplary embodiment in Fig. 4 the flap fold lines 12 and the edge carrier 13. Starting from the stop edges 19, the closure flaps 10 continue to have the bevels running in the direction of the lower edges of the long side walls 3 in order to keep the free areas 21 at the bottom of the folding box free in the finished folding box.

Fig. 5 essentially shows the cut Fig. 2 , but with a molded floor step 32. For this purpose, the in Fig. 4 The bottom flap 8 shown on the right shows the bottom flap 8 in the transverse direction 5 lengthening narrow spacer tab 33 is formed. A wide bottom flap 34 with an adhesive flap 35 at its end adjoins this spacer flap 33 in the transverse direction 5. The spacer flap 33, bottom flap 34 and adhesive flap 35 are pivotably mounted on one another via fold lines 9. The bottom flap 8 is penetrated by two expansion openings 36.

How out Fig. 6 As can be seen, the spacer tab 33 is pivoted through 90 ° with respect to the bottom flap 8 when the floor step 32 is set up. The bottom flap 34 again runs at a 90 ° angle to the spacer flap 33 and extends plane-parallel to the bottom flap 8 underneath. The bottom flap 34 is glued to the long rear side wall 3 with the adhesive flap 35. In addition, two angled support tabs 37 are bent out of the bottom flap 34 and additionally glued to the bottom flap 8 to stabilize the floor step 32. The expansion openings 36 form a passage to the bottom flap 34 in order to erect the floor step 32 without tension.

the Fig. 7 and Fig. 8 show a first variant of a folding box composed of a base part and a hood. With regard to the design and function of the bottom flaps 8 and the closure tabs 10 with their details, the embodiment in FIG Fig. 7 the statements in FIGS. 1 to 3 .

In this special design, the side wall 3 with the discharge opening 4 is only about half the height of the remaining side walls 2, 3. In addition, the adjacent side walls 2 are beveled in the area of the common fold lines 6. The resulting inclined front edges 26 are stabilized by foldable flaps 15. When the crate is set up, a crate is created with an almost completely open front and front edges 26 that run obliquely to the rear. This crate forms the base part of the folding box made up of the base part and hood.

While the other crates described above always have a cuboid outline, the crate is missing Fig. 7 the leading edge as it were. One further crates cannot be stacked up because of the lack of front set-up areas or open areas 22.

This problem is solved by the in Fig. 7 shown hood. The hood has a cover surface 27 and a side surface 28 pivotably mounted on the cover surface 27 by means of a fold line 9. Furthermore, two pivoting wings 29 are mounted on the side surface 28 via fold lines 6. These swivel vanes 29 are swiveled through 90 ° with respect to the side surface 28. The cover surface 27 is also pivoted through 90 ° with respect to the side surface 28. Adhesive wings 30 can in turn be pivoted away from the pivot wings 29 along a fold line 9 by 90 °. They are pivoted to the underside of the cover surface 27 in such a way that the penetration holes 31 in the adhesive wings 30 come to rest on the corresponding penetration holes 31 in the cover surface 27. The adhesive wings 30 are then glued to the underside of the cover surface 27. Finally, the stacking corners 16 cut free from the pivoting wings 29 are glued to the cover surface 27 in the area of the fold line 9. In the finished hood, the penetration holes 31 serve as handle parts for placing the hood on and lifting it off the folding box.

If the hood is on the crate according to Fig. 7 placed on, the side surface 28 closes the loading and unloading opening 4 of the crate. The cover surface 27 closes the top of the crate. The hood stands with the lower edges of the side surface 28 and the swivel wing 29 on the floor of the crate and complements the crate again to form a cuboidal means of transport. The stacking corners 16 on the hood replace the missing stacking corners 16 on the front edge of the tray. This means that several trays can be stacked on top of each other again. The advantage is that the hood can be inserted into the crate when the bottom is still open. The crate is then filled from the ground before the bottom flaps 8 are closed.

While in the embodiment described above, only the two front carrying corners are arranged on the hood, while the rear carrying corners are still part of the base part Fig. 11 a cut of a base part without stacking corners 16. In Fig. 11 the bottom flaps 8 are assigned to the long side walls 3 and the locking tabs 10 are assigned to the short side walls 2. The design of the closure tabs 10 corresponds to that from Fig. 4 .

As in the example according to Fig. 7 and Fig. 8 the side wall 3 with the discharge opening 4 has a significantly lower height than the three remaining side walls 2, 3 of the crate. The resulting inclined front edges 26 are stabilized by foldable flaps 15. When the crate is set up, a crate is created with an almost completely open front and front edges 26 that run obliquely to the rear. This crate forms the base part of the folding box made up of the base part and hood.

The in Fig. 12 shown cut of the base part according to. Fig 11 The associated hood has a cover surface 27 and, on three sides of the cover surface 27, a side surface 28 which is pivotably mounted by means of a fold line 6, 9. On each of the two opposite side surfaces 28 mounted on the narrow sides of the cover surface 27, an adhesive wing 30 is mounted pivotably along a fold line 9. If the two side surfaces 28 on the narrow sides with respect to the cover surface 27 are pivoted by 90 ° by means of the fold lines 6 and the adhesive wings 30 are in turn pivoted by 90 ° with respect to the side surfaces 28, the side surface 28 can be pivoted against the adhesive wings 30 without adhesive wings 30 in such a way that the adhesive wings 30 are glued to the side surface 28 without adhesive wings 30 to form a hood with three side walls 28 protruding at right angles from the cover surface 27. At the same time 30 stacking corners 16 are pivotably mounted on the adhesive wings 30 and are glued to the cover surface 27.

Pivoting vanes 29 are pivotably mounted on the edges of the side surfaces 28 opposite the adhesive vanes 30. The pivoting wings 29 in turn have pivotable stacking corners 16 which are also glued to the cover surface 27. Finally, through holes 31 are formed in the cover surface 27. These penetration holes 31 are used in the finished Cover as handle parts to put on and lift off the cover from the in Fig. 11 shown base part of the folding box. With the cut out Fig. 12 is a hood analogous to that in Fig. 9 The hood shown can be realized, but with stacking corners 16 in all four corners of the cover surface 27.

Fig. 13 and Fig. 14 show a further example of a folding box composed of a base part and a hood. The base part is designed as a so-called tray. The side walls 2, 3 of the in Fig. 13 The base part shown have side walls 2, 3 of essentially the same height. A discharge opening 4 is provided in a long side wall 3. The other side walls 2, 3 have folding tabs 15 on their upper edges. The assignment of side walls 2, 3, bottom flaps 8 and locking tabs 10 corresponds to that in FIG Fig. 11 .

In the base part goods can be set that protrude beyond the side walls 2, 3 in height. The in Fig. 14 The hood shown is therefore designed in such a way that it has side surfaces 28 that are so high that the hood placed on the base part clearly exceeds the height of the side walls 2, 3 of the base part. The hood in turn consists of a central cover surface 27 with two penetration holes 31 as a handle. On two opposite fold lines 9, two side surfaces 28 are pivotably mounted with their long sides on the cover surface 27. On the opposite short sides of each side surface 28, a pivoting wing 29 is pivotably mounted on a fold line 6. On the opposite short sides of the cover surface 27, two adhesive wings 30 are mounted on fold lines 6. Finally, stacking corners 16 are cut free from each adhesive wing 29 and are hinged to folding lines 9 on the pivoting wings 29.

To complete the hood, the side surfaces 28 opposite the cover surface 27, the pivoting wings 29 opposite the side surfaces 28 and the adhesive wings 30 opposite the cover surface 27 are each pivoted 90 ° towards each other and the pivoting wings 29 are glued to the adhesive wings 30. The stacking corners 16 are pivoted onto the cover surface 27 and fixed in the corner regions of the cover surface 27.

In this way, the complements on the base part according to Fig. 13 attached hood turns the base part into a stackable folding box. It is advantageous here that different materials can also be used for the base part and the hood.

Fig. 15 shows the base part Fig. 11 for the folding box with modified bottom flaps 8. A spacer flap 33 and a wide bottom flap 34 each adjoin both bottom flaps 8 in the transverse direction 5. The two wide bottom flaps 34 are pivoted into the interior of the base part with closed bottom flaps 8 in the finished base part and are connected to one another at their free ends. This results in a presentation area for the goods that slopes down from the rear side wall 2 of the base part to the unloading opening 4. This presentation area acts like the floor of a theater stage and slopes down in the direction of the discharge opening 4.

Fig. 16 shows the base part Fig. 11 for the folding box with a modified bottom flap 8. The right bottom flap 8 is extended in the transverse direction 5. A contact surface 38 can be pivoted from the bottom flap 8 about a fold line 9 into the interior of the base part. With an adhesive flap 35 extending the contact surface 38 in the transverse direction 5, the contact surface 38 is fixed on the inside of the associated long side wall 3 in such a way that it is inclined to the bottom of the base part. The contact surface 38 thus forms a rear wall inclined to the rear in the base part, on which products are leaned and do not tilt forward.

Fig. 17 shows a substantially the base part Fig. 11 corresponding base part. In the case of this base part, however, the discharge opening is made in a short side wall 2. The bottom flaps 8 are also pivotably mounted on the lower ends of the short side walls 2. The locking tabs 10 are correspondingly pivoted on the long side walls 3. A spacer tab 33 and a wide bottom tab 34 each adjoin both bottom flaps 8 in the transverse direction 5. The two wide bottom flaps 34 are in the finished base part with closed bottom flaps 8 in the interior of the Base part pivoted and connected to one another at their free ends. Since the spacer tabs 33 have identical dimensions, there is a continuous, flat presentation surface for the goods. Four circular circular openings 39 are cut out of each of the square bottom flaps, so that the presentation area has a total of eight circular openings 39. A cylindrical object, for example a juice glass or a yogurt cup, can be placed in each opening 39 and is thus secured in a form-fitting manner in the presentation area. Two expansion openings 36 finally form a passage to the associated bottom flap 34 in order to be able to align it.
