Container, in particular in the form of a cuboid box with at least two cuts made of foldable and collapsible material

The invention relates to a container, in particular in the form of a cuboid box, which comprises base, side wall and lid elements for safely enclosing individual goods stored therein during transport and which can be folded from a first load-bearing, inherently stable spatial form intended for the transport of goods into a second spatial form intended for its empty transport, whereby the container comprises at least two cut-outs made of foldable and foldable material such as corrugated cardboard or cardboard, provided with desired folding lines such as folding lines or the like for unfolding or folding into the spatial forms and whose dimensions are coordinated with one another to form the spatial forms and which can be easily assembled or disassembled, of which a first cut-out forms a base part with an edge that can be folded up around folding lines and a second cut-out forms an insert part that can be inserted into the base part with a base surface and container side wall elements that can be folded up and in and are hinged to it via folding lines.

A container of the type mentioned is known from DE 84 22 07 6 Ul. It is used today as packaging for e.g. medicines, books, records and much more in an environmentally friendly reusable system in order to effectively avoid packaging waste through repeated use and recycling disposal. The packaging manufacturer delivers the reusable packaging or box to a sender for filling with individual goods, who then delivers the filled boxes, assembled into the first spatial form, to the recipient via a transport company. These bring

the emptied boxes into the second space-saving spatial form in order to return them to the packaging manufacturer or sender. There, the packaging boxes are sorted, material qualified and cleaned. The individual parts of the packaging, such as the base part and insert part, are separated from one another and - if necessary - partially reassembled with exchanged parts made from cut pieces, so that they are then available again in the first spatial form for the transport of goods or in the second spatial form for the transport of empty items. For optimal and efficient use of the reusable container, it is essential that the parts of the container can be easily assembled and disassembled and that the parts are or remain firmly fixed to one another in both spatial forms, especially when transferring the container from the first spatial form to the second spatial form. These objectives are not satisfactorily achieved in the container made from foldable and foldable material cuts with a relatively low specific weight in accordance with DE 84 22 076 Ul. In this case, the insert part is fixed in the base part either by the insert part being able to be inserted into the base part by fitting snugly against opposite wall element surfaces or by the insert part having foldable base flaps on its base surface underneath these, which can be inserted into the base part by clamping them along their edges. In the goods transport spatial form, the fixation should be significantly supported by clamping forces caused by stored goods. It has been found that in all cases the desired cohesion between the insert part and the base part and, if necessary, an additional lid part is insufficient and is lost, particularly in the case of transport vibrations and/or containers tipping on their side, whereby these disadvantages occur particularly in the intended reusable use of the container as a result of deformation of the foldable and collapsible material. In addition, the foldable base flaps of the insert

part of the known container can only be handled with difficulty when dismantling it, by grasping sharp edges that can cause injuries and by excessive deformation of the side edges of the base part. The design of the foldable insert part base flaps also results in a significant increase in the weight of the insert part cut. In order to counteract the inadequate cohesion between the insert part and the base part, in practice it has even been possible to glue the lower surface of the insert part to the base part base surface. However, this negates the use of the container as reusable packaging with regard to the exchange, cleaning, reconditioning and/or recycling disposal of container parts.

In contrast, the invention is based on the object of creating an improved container for reusable use, the parts of which should remain firmly and immovably joined together in the spatial shapes formed during the transport of goods and/or empty, but the parts should be easy to join together or separate from one another in the empty transport spatial shape without causing any damage through quick and convenient handling.

This task is solved in conjunction with the features of the container mentioned at the beginning in that plug-in tabs are formed on the base surface of the insert part and recesses are provided on the base part for locking the plug-in tabs, whereby the insert part can be connected to the base part in a captive manner. Due to the tab/recess locking connection according to the invention between the insert part and the base part, it is achieved that the fixation on opposite sections of the base part edge is only formed by the insert part plug-in tabs that can be locked or snapped into the base part recesses, so that a clamping system over relatively large wall element surfaces or along inadequate clamping edges of the insert part base surface is avoided. The

-A-

The insert part remains firmly locked to the base part during empty and goods transport. A relative movement and displacement between the base part and the insert part in a perpendicular direction to the base surfaces, which is unavoidable with conventional containers under transport conditions, is reliably avoided. In particular, it is also achieved that a container lid element does not undesirably come loose from its locking seat. On the other hand, it is ensured that the insert part can be conveniently and easily inserted into the base part or can be removed from the base part by disengaging the plug-in tabs from the locking recesses, while avoiding fitting surfaces or edges that hinder easy handling.

A preferred embodiment of the invention consists in that a pair of plug-in tabs is formed on opposite side edges, and preferably exclusively on two opposite side edges of the insert part base surface, whereby these extend out of the surface area in the plane of the insert part base surface, and that the associated locking recesses are formed as slots on the base part edge adjacent to the folding line that guides the latter for folding up. In this case, it is completely sufficient for the insert part to be reliably fixed to the base part that the insertion length of the tab plug-in edge that can be snapped into the respective recess corresponds to the material thickness of the first base part cut. On the other hand, this ensures that the tabs snap into the recesses easily and, conversely, that they snap out of the recesses easily in order to permanently join the insert part to the base part or to detach it from the base part for the desired disassembly. It is also important that the tab insertion edges remain undamaged. This means that the tab insertion edges are not obstructed or even damaged by the edge of the base when inserting the insert into or removing it from the base.

be bent. This is normally ensured by the elasticity of the material of the upper area of the base part edge. It may also be advisable for the upper part of the base part edge to be slightly wider than the lower part in order to reliably prevent any damage to the tabs. Due to the minimal insertion length of the tabs, they sit in the base wall locking recesses without protruding through the base part edge. It is particularly advantageous to design the base part edge as a folded edge. The slot locking recesses are designed in a particularly simple manufacturing process by appropriate material separations on the edges of the same that are free in the cut.

According to the invention, a particularly advantageous design of the insert part consists in the insert part blank being designed with a pair of longitudinal side wall elements which are hinged to the longitudinal sides of the insert part base surface which have the plug-in tabs. The plug-in tabs, which in this or any other embodiment are preferably designed to narrow towards the plug-in edge, are cut into the insert part blank by corresponding U- or trapezoid-shaped punch lines, namely from a fold line which hinges the longitudinal side wall element to the insert part base surface, up to the longitudinal side wall, so that each plug-in tab remains in the plane of the insert part base surface when the side wall element is folded up or in.

In the described embodiment according to the invention with a pair of insert part longitudinal side wall elements, it is particularly expedient that the longitudinal dimension of the insert part base surface is dimensioned such that it lies snugly against the base part edge along its broad side material edges. This makes it easy to position and adjust the insertion

■i ■» t

tabs in relation to the corresponding locking recesses in the base part edge and a fixing of the insert part to the base part via its longitudinal dimension, without the slot width of the recesses for the tabs having to be adapted to their width. The slot width of the recess only has to be sufficiently larger than the tab width.

It is particularly advantageous that the plug-in tabs protruding from the base surface of the insert part are so long that in the second container space a gap or space is created between the base edge of the insert part in the folded state and the edge of the base part, into which a user can easily reach with his hand in order to release the insert part from the base part by unlocking the plug-in tabs from the locking recesses. The dimension of the base surface of the insert part is therefore smaller than the corresponding container internal dimension of the base part base surface by the dimensions bridged by the plug-in tabs.

In a special embodiment of the invention, it is provided that each insert part side wall element is hinged to the side edges of the insert part base surface, which have the plug-in tabs, via two parallel grooves, which form an outer folding groove line and an inner folding groove line in the insert part cut. It is particularly expedient that the parallel distance of the outer folding groove line from the associated inner folding groove line corresponds to the dimension bridged by the plug-in tab between the folded insert part and the base part edge. According to a further special feature of the invention, all pairs of parallel inner and outer folding groove lines have the same common parallel distance. This uniform dimensioning of the groove spacing is in itself a significant improvement over the container known from DE 84 22 07 6 Ul. There, in order to improve the

ratio, it is considered necessary to provide the groove spacing on one long side of the floor surface equal to twice the material thickness and the groove spacing on the other long side of the floor surface equal to four times the material thickness of the insert part cut. In practice, this leads to considerable difficulties, since the insert part wall elements have to be unfolded or folded together in a predetermined order. Numbers are therefore printed on the wall elements of the known reusable box in order to enable handling in the correct order according to instructions also printed on the box. These user instructions are no longer required due to the solution according to the invention with uniformly equal groove spacing, since this means that the insert part wall elements can be unfolded or folded together in any order to produce the first and second spatial form. An additional particularly advantageous measure of the invention is that the uniform common groove spacing is smaller than the sum of the material thicknesses of all foldable insert part side wall elements, whereby it is preferably about 15 - 20% smaller than the sum of the material thicknesses. In addition, it is particularly expedient to provide the edge length of the side wall elements hinged to the sides of the tabs, which determines the height of the erected insert part, to be essentially the same as the distance between the parallel inner folding groove lines of the insert part base surface. Both the uniform groove spacing and, to a greater extent, the dimensioning of the side wall elements in relation to the insert part base surface result in the side wall element lying at the top of the empty transport container springing up slightly in the state of the second container spatial shape, which is therefore particularly easy to grasp for erecting the insert part. Also, at least in the area of a pair of grooves (inner and outer fold line) in the state of the second container spatial form, a rounding occurs, which allows particularly easy access under the

The insert part can be grasped by the base surface of the spare part, so that this grip option makes it particularly easy to disengage the insertion tabs from the corresponding locking recesses and to remove the insert part from the base part effortlessly, eliminating the risk of hand injuries from sharp corrugated cardboard edges.

Still other particular embodiments of the invention emerge from the subclaims.

Further advantages and embodiments or possibilities of the invention are described in the following description of the embodiments shown in the schematic drawing. They show

Fig. 3 shows a third blank for producing a lid element for a container according to the invention,

Fig. 4 shows an insert part erected from the blank in Figure 2 in the state for filling with individual goods and

Fig. 5 shows an exploded view of the elements folded from the blanks in Figures 1 to 3 during assembly or disassembly of a container according to the invention.

The blanks 1, 2 and 3 shown in Fig. 1 to 3 are used to produce a base part 10, a

Set part 20 and a lid part 30. A container according to the invention is assembled from these parts, which are shown in Fig. 4 and 5. The blanks are made from corrugated cardboard by cutting a running corrugated cardboard web on a conventional machine and punching it into the desired shape.

A rectangular base area of the first blank 1 (Fig. 1) forms a base area 11, which is surrounded by two broad side edges 123 and two long side edges 124 to form a base part edge 12. These edges are separated from the base area 11 by folding lines 4 and can therefore be folded open. A folding edge 125 is arranged on the long side edges 124, which can be folded using corresponding double folding lines 43, and which is folded inwards when the base part 10 is erected into the shape shown in Fig. 5. In this case, corner tabs 16 engage between the long side edge 124 and the folding edge 125, which are provided in the blank 1 as an extension of the broad side edges 123 and are separated from the long side edges 124 by cutting lines 160. The rolled-up edge 125, which is rolled up downwards around the folded-up corner flaps 16, is anchored by means of lugs 126 provided on its free edges in slotted recesses 127 provided in the corresponding edge area of the base surface 11, so that extremely stable long sides of the surrounding base part edge 12 are formed. Furthermore, side wall flaps 13 are provided on the outer edge of the wide side edges 123, delimited by folding lines 46, which have gripping aids in the form of a cutout 5.

An essential feature of the invention is that locking recesses 15 are provided on the base part edge 12 in Fig. 5, which serve to fix the insert part 20 to the base part 10 by snapping or locking in the plug-in tabs 25 (Fig. 5) arranged on the insert part 20. Each

The locking recess 15 is formed in the base part blank 1 by a rectangular material separation or punching 150 on the free edges of the rolled edges 125, namely between the pair of lugs 126 and immediately adjacent to each lug 126. The slot height h of each locking recess 15 provided thereby corresponds approximately to the material thickness of the blank 2. In the erected base part 10, a depth of insertion is created on the rolled edge 125 that is essentially equal to the material thickness of the blank 1. It can be seen that the locking recess 15 in the erected base part 10 lies directly on the base surface 11 (Fig. 5) and that the recess 15 is only created on the inside of the edge 12, while on the outside this is smooth and recess-free due to the long side edges 124.

The wave pattern of the first cut 1 can be seen at A. This results in a standing wave in the area of the long side edges 124 or the rolled edges 125, i.e. an increased resistance to absorbing compressive forces in this area.

In Fig. 2, the second blank 2 for forming the insert part 20 (see Fig. 4 and 5) is shown. It comprises a substantially rectangular base surface 21, on which, separated by folding lines 41, longitudinal side wall elements

22 are arranged to form the long side walls of the container in the first spatial form (goods transport) (see Fig. 4). In extension of the long side wall elements 22, wide side wall elements are delimited by slightly conical outward-running groove lines 44.

23 are provided. These are each provided with a handle element in the form of a cut-out 5. In the finished container, these cut-outs are congruent with the gripping aid cut-outs 5 of the first blank 1 or the base part 10. The broad side wall elements 23 extend as rectangular surface parts from the slightly conical groove line 44, so that in the opened

- 11 -

In the upright state of the insert part 20, a slight conicity of the side walls 22, 23, i.e. an extension of the upright insert part 20 upwards, results.

In order to be able to fold the insert part 20 into the second container spatial form intended for empty transport and thus to only a small volume, as can be seen from Fig. 5, an inner folding line 42 is provided in the blank interior or the base surface 21 parallel to the longitudinal limiting folding line 41 (outer folding line). Both pairs of parallel inner and outer folding folding lines, which are provided with the reference number 40 and are referred to as creases, have the same common parallel distance M. This is smaller than the sum of the material thicknesses of all foldable insert part side wall elements 22, 23 determined by the blank thickness. The edge length H determining the height of the erected insert part 20
the longitudinal side wall elements 22 each have substantially the same or a slightly smaller dimension as or than the distance B between the inner folding lines 42 parallel on the insert part base surface 21.

On the insert part base surface 21, a pair of insertion tabs 25 is formed on each long side, which
are dimensioned and arranged so that they correspond in the container with the locking recesses 15 on the bottom part edge 12, as can be seen from Fig. 4 and 5
The tabs 25 are therefore intended to be inserted with their free insertion edge, the insertion length of which is s
approximately equal to the material thickness of cut 1 or
slightly larger than this material thickness, to engage or snap into the locking recesses 15, so that the insert part 20 is firmly and captively fixed to the base part 10 in the two spatial forms of the container.

- 12 -

- 12 -

As can be seen from Fig. 2, in the blank 2 each insertion tab 25 extends over the distance M of the double grooves 40, protruding into the flat longitudinal side wall element 22 by the dimension s. The trapezoidal punch line cut 250 cutting out the tab 25 starts from the inner folding groove line 42, so that this inner groove line 42 as well as the outer groove line 41 are interrupted by the tabs 25. In the state of the second container spatial form (empty transport), the tabs 25 bridge a distance or gap that then arises between the folded insert part 20 and the folded edge 125 of the base part 10. The insert part base surface 21 is determined by the inner groove lines 42. In the state of the first container spatial form (transport of goods), the long side wall elements 22 of the insert part 20, which is then erected and inserted into the base part 10, come to rest on the inner surfaces of the folding edges 125 in the container, since the inner width dimension D of the base part 10 is essentially equal to the dimension B+2M. The longitudinal dimension L of the insert part base surface 21 is dimensioned such that it lies snugly against the base part edge along its broad side material edges.

When the insert part 20 is made of corrugated cardboard, the waves in the blank 2 have the course shown at C, which results in a standing wave in all side wall elements 22, 23 for the optimal absorption of compressive forces. The insert part is advantageously made of a two-layer corrugated cardboard blank, while blanks made of single-layer corrugated cardboard are provided for the base part 10 and the cover element 30 described below.

The third blank 3 (Fig. 3) has a basic structure that is in principle similar to that of the first blank 1. However, there are no side wall flaps hinged to the outer edge of the broad side edges, but instead there is also a hinged side wall flap on the broad side edge 323 as well as on every long side.

A folded edge 328 is hinged to the long edge 324 via a double fold line 43. This creates a peripheral edge 32 for the cover element 30 erected from the blank 3 (see Fig. 5), which is formed with the folded edges 325 and 328 folded inwards. In this case, corner tabs 37 engage between the wide edge 323 and the folded edge 328, which are provided in the blank 3 as an extension of the long side edges 324 and are separated from the wide side edges 323 and from second corner tabs 36 by cutting lines 360. The second corner tabs 36 are provided for engagement between the long side edge 324 and the folded edge 325. These corner tabs 36 are provided in the blank 3 as an extension of the folded edges 328. Overall, this results in an extraordinarily stable cover element 30, the corrugation of which preferably lies parallel to the longitudinal side edges, as indicated at E.

The inner dimensions of the cover surface of the erected cover element 30 are slightly smaller than the corresponding outer dimensions of the base part 10.

To assemble the container according to the invention, the folded insert part 20 (middle part in Fig. 5) is first inserted into the base part 10 (lower part in Fig. 5) which is erected with edges 12 and side wall flaps 13, by first placing the tabs of one pair of tabs 251 in the associated locking recesses 15 by slightly slanting the folded insert part 20, whereby then by pressing down the folded insert part, the tabs on the opposite side edge also snap into the associated locking recesses. To produce the empty transport container space shape, the base part side wall flaps 13 are folded in and the lid element 30 is placed over the base part edge 12 in a clamping and form-fitting manner. In the embodiment according to the invention with upwardly springing insert side wall elements 22, which is not shown in Fig. 5

- 14 -

is, the side wall elements 22 or the wide side wall elements 23 located between them are pressed down by the lid element 30 against a slight curvature over the flaps 13. The snug fit of the lid element 30 on the base part 10 is completely sufficient to keep the empty transport container reliably closed. The main advantage of the embodiment is that after the lid element 30 is removed from the empty transport container, the base part side wall flaps 13 are automatically placed in the vertical position according to the lower illustration of the figure due to the insert part side wall elements 22, 23 then springing up. Then, to form the first box container spatial form (goods transport), the insert part side wall elements 22, 23 are raised, i.e. brought into a position according to Fig. 4, with the insert part 20 then being inserted into the base part 10. The side wall flaps 13 overlap the broad side wall elements 23, whereby the gripping cutouts 5 lie flush against one another. After filling the erected insert part 20 with individual items, the container is closed with its lid element 30, whereby this is placed on the insert part or with its edge 32 over the upper areas of the flaps 13 and side wall elements 22, 23. Since the insert part 20 is slightly conical in the erected state, the form-fitting and clamping fit of the lid element 30 is ensured. However, it should be noted that it is not necessary to provide fold lines that cause conicity for such a firm fit. The lid element 30 is already held in a firm fit by the side wall flaps 13 resting on the broad side wall elements 23 (erected state). In addition, by storing goods in the insert part 20 and the forces exerted thereby, the insert part 20 is expanded somewhat upwards due to the elastic corrugated cardboard material, so that the upper areas of the longitudinal side wall elements 22 also become

S ·( &idgr;

clamping system on the longitudinal edge 32 of the cover element 3 O.

After removing the goods from the container in the goods transport spatial form, they can be quickly and easily brought back into the empty transport spatial form by folding the broad side wall elements 23 against the long side wall elements 22 and then folding all the elements down together, whereby according to the described embodiment with a uniform groove spacing M, it makes no difference which long side element 22 is folded down first. By putting on the cover element 30, the completely closed empty transport container is then obtained again.

A significant advantage of the invention is that the insert part 20 is fixed to the base part in a way that cannot be lost both in the first container spatial form and in the second container spatial form by the tab/recess connection, without the need for clamping forces to be exerted by the stored goods in the first spatial form for fixing. The fixing of the insert part to the base part according to the invention significantly improves the overall cohesion of the package in both spatial forms. In particular, it is also reliably achieved that the lid element 30 cannot intentionally move upwards out of its positive seat due to the offset of the insert part prevented by the fixing. On the other hand, it is ensured that the container can be quickly and easily separated into its individual parts 10, 20 and 30 after the lid element has been removed from the first container in the empty state in order to clean, replace and/or recondition parts.
