Description

[0001] The invention relates to a folding box for packaging, storing or protecting goods, with an outer shell, wherein the outer shell has at least three, preferably four, side walls, a top and a bottom, wherein uprights are at least partially arranged at the corner edges of the side walls and wherein the side walls have connecting elements on the bottom and / or on the top for connecting to the uprights.

[0002] Folding crates are used for transporting and storing a wide variety of goods. These crates not only protect the goods but also allow them to be stacked. Mechanical stability and load-bearing capacity are essential, especially for heavy items stacked on top of each other, to ensure that multiple items are at least partially enclosed by the crates. These folding crates can be used as single-use or reusable packaging, meaning they can be used repeatedly.

[0003] A folding crate can be folded into a largely flat position, making it easy to stack and transport. In this flat position, the side walls lie at least partially on top of each other. When the crate is needed, it is unfolded, creating space between the side walls. It is very advantageous if the uprights can be stored separately from the outer shell while the crate is folded, to ensure good stackability in this position.

[0004] Goods or stored goods refer to products or materials of all kinds, for example machines or their parts, food, etc.

[0005] CN 205707739 U shows a folding box with recesses on the top or bottom walls into which uprights can be inserted. These uprights increase the box's load-bearing capacity and distribute the weight of any object placed on top of it. However, this has a disadvantage because it creates openings in the box, allowing the uprights to slip through. Furthermore, the uprights can fall over if they are not engaged with the walls on both sides.

[0006] KR 20 0468026 Y1 describes a folding box in which the side walls have tabs that form recesses into which the uprights are glued. This allows for a more stable connection between the uprights and the side walls. However, this design necessitates the use of adhesives, which is disadvantageous for sensitive goods such as food. Furthermore, the assembly is relatively complicated, as the upright and the tab must be held in position until the adhesive has cured.

[0007] In the KR 100 976 392 B2 another folding box with stand is shown.

[0008] When using uprights in a folding box, it is essential that they restrict the interior space as little as possible. Furthermore, quick and easy assembly is crucial. If the uprights are attached to the outer shell, preferably on the inside, they can easily tip over or slip into an unfavorable position during assembly. This complicates the process. Additionally, the uprights typically have a specific cross-section that, in a particular position, can bear a particularly high load. For example, such uprights may have multiple legs that can be at least partially movable relative to each other. If these legs are in an unfavorable position, the uprights' load-bearing capacity can be reduced. Therefore, it is necessary to check that the uprights are in their optimal position immediately before or during assembly, which is time-consuming.

[0009] The object of the invention is therefore to provide a folding box of the described type which has a high load-bearing capacity, but is also easy and quick to assemble.

[0010] This problem is solved according to the invention by providing that the connecting elements are designed to compensate for positional tolerances and / or form tolerances of the uprights by providing that Tabs are arranged on the underside of the lower edges of the side walls, and that the connecting elements at least partially comprise receptacles in which the uprights are arranged, and that the receptacles are at least partially formed by the tabs of the side walls, which are connected to the tabs of the adjacent side walls via plug-in or folding connections, and the uprights are inserted into the receptacles; and / or by providing that at least one side wall has at least one cover flap with at least one connecting element on the top and / or bottom, and that this connecting element comprises a recess that accommodates at least one upright.

[0011] Compensating for positional and / or form tolerances allows for simpler assembly, as the connecting elements then bring the uprights into their intended position or orientation during assembly.

[0012] Position tolerances refer to minor deviations in the position of the uprights from their intended position, which arise due to natural manufacturing and material tolerances as well as material elasticities.

[0013] Form tolerances refer to deviations in the shape or position of the uprights from their intended form, caused by internal stresses or external forces acting upon them. For example, with L-shaped uprights made of solid cardboard, the legs may not be at the ideal 90° angle, but rather at a smaller angle. This makes them less load-bearing.

[0014] It can preferably be provided that at least one upright has at least two legs and the connecting elements are designed to push at least two of the legs into a defined position, preferably pushing them apart.

[0015] It may be stipulated that at least the side walls are made of cardboard and preferably the outer shell is designed as a folding box. The cardboard may be coated, for example with PP. The coating can be on one or both sides and, for example, be waterproof.

[0016] It can also be provided that at least the side walls, preferably the outer shell, are made of plastic, preferably of multi-wall polycarbonate sheets. Multi-wall polycarbonate sheets are plastic sheets with elongated hollow chambers that extend along a longitudinal direction of the plastic sheet.

[0017] According to the invention, the connecting elements at least partially comprise receptacles in which the uprights are arranged, and the receptacles are at least partially formed by tabs of the side walls which are connected to the tabs of the adjacent side walls via plug or folding connections, and the uprights are inserted into the receptacles.

[0018] The term "receiver" refers to an arrangement that limits the movement of the upright in at least one direction, thereby holding it in place and imposing a specific position and configuration. Preferably, the receiver limits the movement of the upright along a vertical axis in at least one direction and along a horizontal axis perpendicular to the vertical axis in both directions. The receivers are located in the region of the corner edges of the side walls and at least on the underside, and are formed at least partially by the tabs of the adjoining side walls.

[0019] The side walls of the folding box abut each other and serve both to protect the goods placed inside and to at least partially absorb weight. For this purpose, the side walls are preferably flat, although they may also have cutouts, for example, for gripping the box. The top and bottom are located on the sides of the side walls that are free of other side walls. If three side walls are provided, a prismatic folding box with a triangular top and bottom is formed. With four side walls, a cuboid can be formed. Folding boxes with more side walls, for example, with eight side walls, are also possible. This can result in octabins.

[0020] Additional upper or lower walls may be arranged on the top and / or bottom, which further close the folding box and better protect the stored goods. However, it is also possible for the top and / or bottom to remain open or partially open.

[0021] It may be designed so that each tab is integrally connected to at least one side wall. Alternatively, the tabs may also be glued or attached using connecting elements, folding or plug-in connections.

[0022] Preferably, at least on the top side, an upper wall is arranged, which is formed at least partially from tabs of the side walls. This creates a cardboard cover that is very easy to assemble and can be placed over a product.

[0023] This refers to directional or positional specifications such as top, bottom, sideways, horizontal, or vertical in relation to the intended use of the folding box, where the top is on top and the bottom is on the bottom. Of course, the folding box can also have other uses, for example, when the bottom is on top and the top is on the bottom, or when one side wall is on top and the top and bottom are on the side.

[0024] Corner edges refer to the edges formed where two side walls meet. Uprights can be positioned inside the folding box along these, usually elongated, edge areas. Alternatively, the uprights can also be positioned outside the folding box.

[0025] Uprights are reinforcing elements that can absorb forces in at least one direction, preferably along their longitudinal axis, and thus serve to support the folding box. The uprights preferably rest against the side walls in the area of ​​the corner edges.

[0026] The uprights can be positioned on the inside of the side walls in the area of ​​the corner edges. They can also be positioned on the outside of the side walls in the area of ​​the corner edges.

[0027] The side walls are preferably at least partially made in one piece.

[0028] Plug-in or folding connections refer to connections between side walls that are created by sliding parts of the tabs into one another, underneath, over or next to each other, or by interlocking them.

[0029] This type of connection allows for the simple creation of a stable receptacle that remains dimensionally stable even without the use of adhesives or other additional fasteners such as screws or clamps. The receptacle can be formed first, and then the upright inserted. This eliminates the need for adhesives or fasteners to hold the upright in place. Preferably, the connection to the upright is adhesive-free. This speeds up and simplifies assembly. Furthermore, the upright can be easily removed if necessary.

[0030] Furthermore, the brackets automatically hold themselves in the assembled position, allowing the box to be assembled before the stand is inserted. Additionally, the bracket can hold the stand's position while the folding box is not yet fully assembled, greatly simplifying handling.

[0031] It is particularly advantageous if the tabs used to form the plug-in or folding connections have at least partially slotted, recessed, and / or tongue-shaped fastening elements. This enables a stable connection that defines the shape and arrangement of the tabs. At the same time, this connection is easily and repeatedly detachable, allowing for repeated disassembly and reassembly. Tongues can be inserted into slots or recesses. Combinations of both can also be advantageous. Furthermore, combining this with other connection types such as gluing, screwing, riveting, and the like can result in an even stronger connection.

[0032] Furthermore, it can be provided that, in at least one assembly, a first tab of a first side wall has a tongue pointing towards a second tab of a second side wall, and the second tab has a recess pointing towards the first tab, the shape of the recess preferably corresponding to the shape of the tongue. This allows the tabs to be bent and raised towards their respective side walls, and the tongue to be inserted into the recess, thus preventing the tabs from moving back due to restoring forces. The tabs thus mutually inhibit their return movement and remain in the intended position. Alternatively, a slot can be provided instead of a recess. It is important that the tongue or the recess is oriented towards the second or first side wall, respectively, in the intended assembled position.

[0033] It is advantageous if the tongues, slots and / or recesses, at least partially, point towards the adjacent side wall with which they form a recess when assembled. This allows for optimal force transmission between the fastening elements.

[0034] The tongue preferably has a rectangular or trapezoidal shape.

[0035] It can be provided that at least one tongue has a length that preferably lies between the thickness of the tab and twice the thickness of the tab to which it connects in the assembled state. The tongue can have an average width that is a multiple of its length. The depth of the recess or slot preferably corresponds to the length of the tongue. The width of the recess or slot preferably corresponds to the width of the tongue. This achieves a stable connection between the tabs, while at the same time ensuring that parts of the tabs do not obstruct the arrangement of the upright or stand.

[0036] It is particularly advantageous if, in at least one connection, the first tab has at least one tongue and at least one recess, and the second tab has at least one recess corresponding to the shape of the first tongue and at least one second tongue corresponding to the shape of the first recess. The recesses and tongues of the first tab can be arranged along a connecting wall of the first tab, with the connecting wall pointing towards the second tab. This allows for a particularly stable connection.

[0037] To reduce the number of parts that need to be joined and to achieve faster assembly, it can be provided that at least some of the tabs, preferably all tabs, are made in one piece with the side walls.

[0038] At least some of the tabs are used to form the recesses. At least one side wall can have at least one tab in the area of ​​each recess. However, to achieve a more stable embodiment, it is advantageous if at least some of the tabs, preferably all of them, extend along the side walls essentially from one corner edge to the other. This allows a central section to form between the tab sections that create the recesses. This means that only one tab is needed on the underside of each side wall, which can be used to form the recesses at both corner edges. It can be provided that the central section is at least partially separated from the tab sections that form the recesses before or after assembly, for example, by cutting it off. It can also be provided that the central section of the folding box is completely removed.

[0039] It is also advantageous if at least one receptacle, preferably each receptacle, has at least one retaining section, and the retaining section runs substantially parallel to at least one side wall, and if at least one receptacle, preferably each receptacle, has at least one bottom section, which is arranged between the side wall and the retaining section on the underside and is substantially parallel to the underside. The bottom section can prevent movement of the upright along its longitudinal axis, while the retaining section can prevent movement of the upright transversely to its longitudinal axis. Thus, in cross-section transverse to a side wall, the receptacle preferably forms a U-shaped space into which a part of the upright can be arranged.

[0040] If the receptacle is arranged on a top surface, it can accordingly be provided that at least one receptacle, preferably each receptacle, has at least one retaining section, and that the retaining section runs substantially parallel to at least one side wall, and that at least one receptacle, preferably each receptacle, has at least one bottom section, which is arranged between the side wall and the retaining section on the top surface and is substantially parallel to the top surface.

[0041] To achieve a particularly stable and secure connection, it can be provided that, in at least one mounting, a distance D between at least one side wall and a holding section parallel to it corresponds to the thickness of the profile of the upright or uprights arranged within it. This fixes the upright or uprights between the side wall and the holding section, preventing them from moving along a vertical axis perpendicular to the upright's longitudinal extent.

[0042] Preferably, the support section has a length that is at least one-tenth the length of the upright. This allows the upright to be held stably in an upright position. Preferably, the length is at least one-quarter, and particularly preferably at least one-third, of the length of the upright. Furthermore, it can be advantageous if the length is between one-quarter and one-third of the length of the upright.

[0043] The simplicity and speed of assembly can be further improved if the tabs are connected to each other exclusively via plug-in or folding connections.

[0044] According to the invention, at least one side wall has a cover flap with at least one connecting element on its upper and / or lower surface, and this connecting element includes a recess that accommodates at least one upright. The cover flap is a tab or flap located on the upper or lower surface of the side wall and designed to at least partially cover the opening of the upper or lower surface when assembled. This facilitates the construction of an upper or lower wall using parts of the side wall. A separate recess can be provided for each upright, or recesses can be provided for several common uprights.

[0045] The cutout can be L-shaped, with at least one of the two legs of the cut being thicker at its end furthest from the other leg than at at least one point between that end and its junction with the other leg. This allows the upright to be easily inserted, and a force can then be applied to move the upright into a specific position. When the lid flap is moved towards a right angle to the side wall, the upright(s) are automatically moved into their intended position. Even if the uprights are not ideally positioned beforehand and protrude into the interior of the folding box, the desired position is achieved immediately with just a few simple steps. Simultaneously, the upright is pressed into a defined configuration in the assembled position. This increases the maximum force-bearing capacity.

[0046] In this sense, it can be particularly advantageous if the inner edges of the legs, or a common inner edge of the legs, are curved, for example, composed of several radii, or designed as a polygonal line or lines. A polygonal line is defined as a line with at least three sections separated by vertices. In other words, the inner edge or edges are concave relative to the outer edges. This allows parts of the upright, such as legs of the upright, to be quickly inserted into the fixture during assembly and simultaneously pressed into a defined position. Minor indentations of the inner edge or edges are less problematic.

[0047] In the simplest case, both legs have an outer and an inner edge. The outer edge is the one located on the outside of the L-shape, and the inner edge is the one located on the inside. However, the inner edges can be curved—that is, they can describe a circular segment or a curve, or be composed of a multitude of curves or a multitude of short straight lines—in such a way that they essentially form a common inner edge. This inner edge can also have corners or projections.

[0048] Furthermore, it can also be advantageous if at least one edge of the cut, at least partially pointing towards a side wall, is curved or designed as a polygonal line.

[0049] For easier manufacturing, the folding crate, preferably with the exception of the uprights, can be made from a single material. By eliminating the need for adhesives or similar materials to connect the folding crate and reinforcing elements, it is ensured that the folding crate has no negative impact on the stored goods. Furthermore, this type of design is particularly easy to dispose of and recycle, as it can be easily disassembled.

[0050] In other words, the connection is free of adhesives, clamps, screws, or other parts not integrally connected to at least one of the tabs.

[0051] It is particularly advantageous if the side walls are made primarily of corrugated cardboard. The corrugated cardboard must have at least one flat and at least one corrugated layer, which are bonded together.

[0052] It can also be advantageous if the uprights are made primarily of solid cardboard. Solid cardboard refers to cardboard that is single-layered, multi-layered, or multi-ply and robust. Alternatively, the uprights can also be made primarily of plastic, which can be solid or have hollow chambers.

[0053] The uprights can have different shapes. It is advantageous if the uprights have an L-shaped profile. This allows the legs of the upright to lie flat against the side wall, thus further stabilizing the folding box.

[0054] To achieve improved stability and increased weight capacity, two uprights can be arranged along each corner edge. These uprights can be positioned, for example, one inside the other or one behind the other.

[0055] It may be planned that recordings are provided on the top and bottom surfaces. These recordings may have different designs.

[0056] Advantageously, it can also be a kit for assembling a folding box of the type described, wherein the kit includes at least one outer part for forming an outer shell encompassing the side walls and at least three uprights. The outer shell can first be assembled from the outer part(s), and then the uprights can be positioned in the corresponding recesses of the outer shell.

[0057] The present invention will now be explained in more detail with reference to the embodiments shown in the figures. These show: Fig. 1a a die-cut pattern of a folding box according to the invention in a first embodiment; Fig. 1 a detail from Fig. 1a ; Fig. 1 shows part of a folding box according to a die-cut pattern made of Fig. 1a and Fig. 1b in a cross-sectional view along line II in the assembled state; Fig. 2a a part of a partially assembled folding box according to a second embodiment in an interior view; Fig. 2b the folding box made of Fig. 2a in a top view with assembly further advanced; Fig. 3 a part of a partially assembled folding box according to a third embodiment in an interior view; Fig. 4 a part of a partially assembled folding box according to a fourth embodiment in an interior view. In Fig. 1a and Fig. 1b A die-cut pattern for an outer part 17, used to form the outer shell of a folding box, is shown. This pattern comprises four rectangular side walls 1, which are formed in one piece. Such a die-cut pattern can be assembled into a folding box together with four or more uprights without any additional tools or parts. In the assembled state, the outermost side walls 1 are joined at their free edges, thus forming a rectangular folding box. These side walls 1 can be glued together at their free edges, for example, or connected by screws, clamps, or plug-in or folding joints. Each side wall has large, rectangular flaps 2a on its upper surface 2, which extend over the entire length of the side walls. By folding the flaps 2a over each other, an upper wall is formed on the upper surface 2, thus closing off the folding box.

[0058] On the underside 3, a tab 4 is arranged at the lower edges of each side wall 1. The tabs 4 extend over the entire length of the lower edges of the side walls 1. Each tab 4 has a retaining part 4a and a base part 4b, with the base part 4b positioned between the retaining part 4a and the side wall 1. The tabs 4 can be folded inwards, in particular towards the interior of the folding box, such that the base part 4b is perpendicular to the side walls 1 and each retaining part 4a is parallel to the side wall 1 to which it is connected via the base part 4b. This allows recesses 15 to be formed in the areas of the corner edges 5 between the side walls 1, with part of the base parts 4b acting as base sections and part of the retaining parts 4a acting as retaining sections.

[0059] The base sections 4b have a trapezoidal shape, the support sections 4a a rectangular shape. The trapezoidal shape serves to form a substantially continuous base section, at least in the area of ​​the exceptions.

[0060] Each tab 4 extends over the entire side edge of its side wall 1, i.e., the side wall 1 on which the tab 4 is located. The portions of the tabs 4 located in the region of the corner edges 5 can therefore be used to form the receptacles 15. Thus, each tab 4 is used for two adjacent receptacles 15. Therefore, the tabs 4 have central sections 10 between the adjacent receptacles 15, which can be separated (dashed lines 9) or completely removed from the parts forming the receptacles 15 before or after assembly.

[0061] On the connecting sides 4c facing the adjacent tabs 4, each tab 4 has a tongue 7 and two recesses 8 on a first connecting side 4c1 and a recess 8 and two tongues 7 on a second connecting side 4c2. These fastening elements are arranged one behind the other along the connecting sides 4c1 and 4c2 and extend in total over the entire length of the connecting sides 4c.

[0062] Starting from the base section 4b, the first connecting side 4c1 has a recess 8 where the first connecting side 4c1 is set back (see center line 11). This recess 8 is followed by a tongue 7, which projects from the first connecting side 4c1. This is followed by another recess 8 extending to the end of the first connecting side 4c1. The tongue 7 and the recesses 8 have trapezoidal shapes.

[0063] The second connecting side 4c2 has a structure corresponding to the shape of the first connecting side 4c1, consisting of a tongue 7 followed by a recess 8, followed by another tongue 7. The recess 8 of the second connecting side 4c2 is slightly longer than the tongue 7 of the first connecting side 4c1. Preferably, this difference is chosen according to the thickness of the tabs 4 to ensure smooth interlocking of the fastening elements.

[0064] Two opposing cover flaps 2a, when assembled, have cutouts 12a with continuously straight edges. This creates an L-shape with straight legs that are at a 90° angle to each other. In the intended installed position, each leg rests against a side wall 1. Alternatively, these two cover flaps 2a can also be without cutouts 12a, in which case they form a continuous surface on the top and prevent the uprights from slipping out.

[0065] The other cover flaps 2b have incisions 12b with partially curved edges. These incisions 12b have outer edges 13a, 13b, with one outer edge 13a positioned directly against the side wall 1 on which the cover flap 2b is located and thus pointing away from it. The other outer edge 13b is arranged such that, in the assembled state, it rests against an adjacent side wall 1 and points away from it. This configuration is found in all incisions 12a, 12b.

[0066] Furthermore, these incisions 12b have inner edges 14 that point towards the side walls 1. These inner edges 14 are curved in a circular segment towards the side walls 1, resulting not in two inner edges 14 per incision 12b, but only one common edge. This results in a concave shape for both legs.

[0067] Thus, the legs of these incisions 12b have a first width B at their outer end regions, which is greater than the thickness of the upright 15 or uprights 15 to be arranged therein, and have a second width b in a middle region of the legs, which corresponds to the thickness of the upright 15 or uprights 15 to be arranged therein.

[0068] All incisions 12a, 12b are located in the corners of the cover flaps 2a, 2b, i.e., in the area of ​​the corner edges 5. The cover flaps 2a, 2b are arranged such that two cover flaps 2a, 2b always lie one above the other in a corner, with each corner always containing one cover flap 2b with a curved second edge 14 and one cover flap 2a with two straight inner edges 14.

[0069] Fig. 1c Figure 1 shows a folding box that has been manufactured according to the die-cutting pattern shown and has already been at least partially assembled. A section is shown in the area of ​​a receptacle 15, perpendicular to a side wall 1. The flap 4 is already folded over, and the tongues 7 and recesses 8 are folded into each other with those of the adjacent flaps 4, thus creating a U-shaped slot in which one leg of a support 15 is positioned. Since the adjacent flap 4 has the same structure, it also forms a corresponding slot in the area of ​​the receptacle 15, which can accommodate another leg of the support 14. The base section 4b is arranged essentially parallel to the underside 3 and lies parallel to a horizontal plane H. The retaining section 4a is essentially parallel to the side wall 1 and to a vertical plane V.Thus, the receptacle 15 has a distance D between the side wall 1 and the retaining part 4a, which preferably corresponds to the thickness of the upright 15 or the thicknesses of the uprights 15 to be arranged therein.

[0070] Thus, the parts of the bottom sections 4b of the adjacent tabs 4, which are arranged in the area of ​​the receptacle 15, together form the bottom section. Similarly, the parts of the retaining sections 4a of the adjacent tabs 4, which are arranged in the area of ​​the receptacle 15, together form the retaining section.

[0071] In Fig. 2a A second embodiment is shown in an assembled state. The tabs 4 are designed as in the first embodiment and, in the shown state, are folded inwards. The tongues 7 of the first and second connecting sides 4c1, 4c2 engage with the respective recesses 8, thus stabilizing the folded form. This results in openings along the side walls 1 with a thickness D, which is defined by the width of the bottom parts 4b. In the areas of the corner edges 5, this creates L-shaped recesses 15.

[0072] Uprights 16 are inserted into these receptacles 15, which have an L-shaped profile corresponding to the receptacles 15 and extend from the receptacles 15 on the inside of the corner edges 5 to the top 2.

[0073] The lid flaps 2a and 2b are shown unfolded for better viewing. They are arranged as shown in Fig. 1a executed, however, only two opposing lid flaps have incisions 13 with curved inner edges 14. In the assembled state, these lid flaps 2b are first folded onto the side walls 1, with the uprights 15 penetrating the incisions 13 at their upper side and being held by them. In Fig. 2b Such a configuration is shown. The curved shape of the inner edges 14 pushes the legs of the stand 15 apart and stabilizes them in this position. The remaining cover flaps 2a are subsequently folded over, thus completely closing the top surface except for a possible gap in the middle.

[0074] The folding box, except for the 15 uprights, is made of corrugated cardboard and is manufactured in one piece; the uprights are made of solid cardboard. Alternatively, the folding box can also have an outer shell made of two pieces.

[0075] In Fig. 3 An alternative embodiment is shown in which the same die-cutting pattern from the second embodiment was used. However, before folding the tabs 4, the central parts 10 were separated from the parts of the retaining part 4a that form the receptacles 15.

[0076] In Fig. 4 Another embodiment is shown, which largely corresponds to the second. However, the messenger section 4b has been made longer, so that two uprights 16 can be inserted into each receptacle 15. For this purpose, the uprights are arranged one behind the other. Accordingly, the notches 13 should also be made larger.
