Description

The invention relates to a packaging container according to the preamble of claim 1, as known from EP 2 256 051 is known.

A packaging container is for example from the DE 20 2008 003 442 U1 known. The casing part of the packaging container is folded in a storage position, so that the packaging container can be stored space-saving. The shell part can be transferred by unfolding under increase in volume in the position of use, in which it is placed on the bottom wall and together with this encloses a packaging space that can be filled with packaged goods.

The US 6,050,410 describes a foldable pallet top container with a flat base mounted on a pallet and a skirt portion secured within the base on a bottom wall. The shell part can be transferred from a folded storage position by folding relative to the ground in a unfolded position of use and vice versa. The container further comprises a lid part, which can be placed in the storage position and in the position of use on the bottom part.

Object of the present invention is to provide a packaging container of the type mentioned, which can be handled in a simpler manner.

This object is achieved by a packaging container with the features of claim 1.

As a side wall in the present case, a wall of the shell part is considered, which forms a side wall of the packaging container in its position of use. In the packaging container according to the invention, a side wall of the casing part, which is referred to below as the first side wall, is fixed movably on the bottom wall by means of at least one fastening member. The first side wall and thus the jacket part are thereby held captive on the bottom part. This makes it easier for a user to handle the packaging container, since the casing part and the bottom part are in a defined relative relationship to one another even when unfolding the casing part from the storage position to the use position. The shell part can be pivoted to transfer from the storage position to the use position relative to the bottom part, wherein the first side wall is transferred, for example, from a position parallel to the storage position in the stocking position to the bottom wall in a direction of use in the use position perpendicular to the bottom wall level.

At least one of the remaining, in particular all other, different from the first side wall side walls of the shell part in its position of use is or can be fixed in each case by means of at least one locking member on the bottom part. By fixing the shell part on the bottom part in the position of use, the shell part is protected against unwanted folding back into the storage position. This ensures the dimensional stability of the packaging container and facilitates its handling.

A structurally simple as well as effective fixation of the shell part on the bottom part is achieved in that the respective at least one locking member is a foldable on the respective side wall about a fold line held locking tab which included in the position of use of the shell part in a respective from the bottom part or fixed to this Recording engages. If the casing part is transferred into the position of use, the respective locking tab can be folded around the folding line relative to the respective side wall and inserted into the respective receptacle of the bottom part. For this purpose, the receptacle is conveniently designed slot-shaped to prevent relative movement of the respective side wall to the bottom part.

The respective locking tab can be held directly or indirectly on the respective side wall.

It is advantageous if the at least one attachment member is a holding lug connected to a lower edge of the first side wall and foldable about a fold line relative thereto. This allows a structurally simple embodiment of the packaging container, in particular when manufactured from a paper material such as corrugated cardboard. The retaining tab is held approximately by gluing or stapling on one of the bottom wall facing the lower edge of the first side wall, based on a use position of the shell part, in particular on a bottom wall facing the lower edge of the first side wall. The fold line defines a pivot axis about which the first side wall can be pivoted relative to the bottom wall when unfolding the shell part.

In a structurally particularly simple embodiment of the packaging container, the retaining tab is formed integrally with the first side wall. For example, the retaining tab and the first side wall adjoin one another at a common edge defining the fold line. This is particularly advantageous in a production of the shell part of a paper material such as corrugated cardboard, when the retaining tab and the first side wall are formed from a one-piece material blank.

Preferably, the retaining tab extends along the entire lower edge of the first side wall, especially along the entire lower edge of the first side wall. The first side wall and the retaining tab thereby enter the largest possible connection area with each other. As a result, the first side wall is reliably fixed to the bottom wall and can be folded relative to the bottom wall in the most well-defined manner possible.

It is advantageous if the retaining tab has a fastening section facing away from the lower edge of the first side wall and fixed on the bottom wall, and a connecting section connecting the fastening section to the lower edge, which can be folded relative to the fastening section by a further fold line. In the storage position of the casing part, the connecting section can assume, for example, an angled position relative to the fastening section fastened to the bottom wall and thereby be aligned approximately transversely to the bottom wall. In addition, the first side wall may be angled relative to the connecting portion and extend approximately parallel or substantially parallel and spaced from the bottom wall. As a result, an intermediate space is formed between the bottom wall and the first side wall, in which further side walls of the shell part can be stored folded in its storage position. For unfolding the jacket part of the connecting portion can be folded about the other fold line relative to the mounting portion until it reaches, for example, for surface contact on the bottom wall. As a result, the first side wall can be converted into a desired position aligned at right angles to the bottom wall, which position assumes it in the position of use of the casing part.

The structural design of the packaging container and its handling are simplified when the former folding line and the other folding line are aligned parallel to each other.

Preferably, the attachment portion relative to a side edge of the bottom wall, along which the first side wall in the position of use of Jacket part extends, a distance equal to or substantially equal to the distance between the fold lines from each other. In the use position of the skirt portion, the space between the side edge and the attachment portion is occupied by the connecting portion of the retaining tab, and the first side wall is aligned or substantially flush with the side edge of the bottom wall. Preferably, the distance is about one wall thickness or two wall thicknesses of the first side wall greater than the distance of the fold lines from each other. This ensures that the first side wall or that the subsequently mentioned cover part, which in the position of use can be placed on the jacket part, does not project beyond the bottom wall in the position of use of the jacket part on the outside.

It is advantageous if at least one opening is formed in the connecting section, that is, it has at least one opening. In an advantageous embodiment of the packaging container, the at least one opening allows the storage of one of the below-mentioned locking tabs of the shell part in its storage position to fold this space saving and to secure the shell part in the storage position.

Preferably, the at least one opening is arranged symmetrically with respect to a plane oriented perpendicular to the bottom wall and the first side wall centrally dividing plane at the connecting portion. This allows the inclusion of locking tabs in the at least one opening when the shell portion occupies the storage position and the locking tabs are arranged symmetrically with respect to the plane.

Conveniently, the casing part is laid flat in the storage position in order to save the packaging container as space-saving as possible. The jacket part is particularly preferably laid flat on the bottom wall, wherein the first side wall can be aligned parallel thereto.

It is advantageous if the casing part is a self-contained strip of material, for example, a plurality of annularly interconnected side walls, one of which is the first side wall. The formation of the shell portion as a strip of material facilitates a user handling the packaging container when unfolded from the storage position into the position of use.

The packaging container can be further stored in a space-saving manner in that the casing part in the storage position does not protrude laterally beyond a bottom surface defined by the bottom wall.

A possibly flattened and space-saving storage position of the shell part is achieved, for example, that in the storage position, the first side wall is spaced from a second side wall of the shell part opposite the first side wall and the further side walls connecting the first side wall to the second side wall Jacket part between the first side wall and the second side wall are arranged folded. In the storage position, the casing part can thus as it were assume a "sandwich" configuration, wherein the first side wall and the opposite second side wall of the casing part receive the remaining side walls between them. In this embodiment, the first side wall is preferably fixed with the above-mentioned, the fastening portion and the connecting portion having retaining tab on the bottom wall and arranged in the storage position of the shell part at a distance from the bottom wall. The second side wall can lie flat against the bottom wall, and in the space between the first and the second side wall, the remaining side walls are stored space-saving.

It is favorable if the casing part comprises two further side walls which connect the first side wall to the second side wall and which are arranged folded in each case in the storage position of the casing part between the first side wall and the second side wall. The jacket part can thus have four side walls, namely the first and the second side wall and two further, these interconnecting side walls. These are folded in the storage position of the casing part in itself, in each case at least one Seitenwandfaltlinie. This allows a particularly space-saving storage of the shell part.

The first side wall is preferably a longitudinal side wall of the shell part.

It is advantageous if at least one of the remaining, in particular all other, different from the first side wall side walls of the shell part at least one relative to this foldable fold line folding flap is fixed at a lower edge, in the position of use of the shell part on the bottom wall rests. At least one and in particular all of the first side wall different side walls of the shell part in each case at least one folding tab is set. In the use position of the shell part, the folding tab can rest flat on the bottom wall. The at least one folding tab is preferably arranged in the interior of the packaging space. By means of the respective folding tabs, the jacket part reliably rests on the bottom wall in the position of use. If the casing part assumes the storage position, the respective folding flap expediently rests flat against that side wall to which it is fixed, so that the casing part can be stored in a space-saving manner. When unfolding the jacket part, the respective folding tab can be folded around the folding line and brought to bear against the bottom wall.

The respective folding tab is preferably fixed to a lower edge of the respective side wall, which faces the bottom wall in the position of use of the shell part, wherein the lower edge defines the fold line. At least one of the below-mentioned locking tabs is favorably connected to the respective folding tab, which is arranged on one side of the folding line opposite the folding tab and can be folded together with the folding tab relative to the respective side wall.

A structurally simple embodiment of the packaging container is advantageously achieved in that the respective at least one folding tab is formed integrally with the respective other side walls. This is particularly advantageous when producing the casing part from a paper material such as corrugated cardboard, wherein the respective side wall and the respective folding tab are made of a one-piece material blank.

Preferably, the respective locking tab engages in a vertical and / or in a direction parallel to the bottom wall direction without play or substantially free of play in the respective recording. The respective side wall can then no longer be raised from the bottom wall and / or be moved in a plane parallel to the bottom wall level. The shell part is thus particularly reliable fixed to the bottom part when it occupies the position of use.

In a structurally simple embodiment of the packaging container, the respective locking tab is formed integrally with the respective side wall. This is particularly advantageous when producing the casing part from a paper material such as corrugated cardboard, wherein the respective side wall and the respective side flap are formed from a one-piece material blank.

Further, the respective locking tab is preferably directly or indirectly connected to a lower edge of the respective side wall in a structurally simple embodiment. In particular, the locking tab is connected to a lower edge of the side wall which faces the bottom wall in the use position of the shell part, the lower edge defining the fold line about which the locking tab is foldable relative to the side wall.

It is particularly advantageous if the respective locking tab is formed in extension of one of the respective side wall folding flap for resting on the bottom wall in the position of use of the shell part and if the folding tab and the locking tab on opposite sides of a common fold line to which the folding tab and the Locking tab with respect to the respective side wall are foldable, are arranged. If the respective folding flap is folded around the fold line relative to the side wall, this also causes a folding of the respective locking tab relative to the respective side wall. The respective folding tab and the respective locking tab are folded in mutually different directions away from the respective side wall, as they are arranged on opposite sides of the common, coincident fold line. This embodiment makes it much easier for a user to transfer the casing part into the position of use and fix it on the bottom part, whereby at the same time the respective folding flap is brought into contact with the bottom wall can be. The respective folding tab can connect the respective locking tab indirectly with the respective side wall.

In the above-described advantageous embodiment of the packaging container, the respective folding tab and the respective locking tab are particularly preferably formed integrally with the respective side wall and held foldable on the, in the use position of the shell part of the bottom wall facing lower edge.

It is advantageous if at least one of the respective locking tabs of a side wall folded in the stocking position of the jacket part, folded around a side wall fold line, extends across the side wall fold line. If the shell part is transferred to the position of use, the folded-in side wall is folded along the Seitenwandfaltlinie until it defines a plane. The locking tab extends across the side wall fold line and can be folded about its associated fold line relative to the side wall to fix it to the bottom part. As a result, the dimensional stability of the casing part in the position of use can be ensured. Undesirable folding back of the respective side wall is largely avoided by the locking tab extending over the side wall fold line.

It is favorable when the bottom part of the respective side wall has an outer wall projecting upwards from the bottom wall and comprising a respective receptacle. In the outer wall, the preferably slot-shaped receptacle is formed, in which the respective locking tab can engage in order to fix the respective side wall to the outer wall and thus to the bottom part.

The respective side wall is located on the associated outer wall in the position of use of the shell part conveniently flat. This will be discussed below.

Preferably, the packaging container comprises a pallet on which the bottom part is fixed. This allows a robust construction of the packaging container and facilitates its transport, especially if it is a wooden pallet and especially a standardized "Euro pallet".

Advantageously, the shell part is fixed together with the bottom part on the pallet in order to simplify the structural design of the packaging container. For example, the shell part is stitched by means of the above-mentioned retaining tab through the bottom wall with the pallet.

It is advantageous if the packaging container comprises a cover wall forming a cover part, which, a storage state of the packaging container, releasably placed in the storage position of the shell part on the bottom part, wherein between the bottom wall and the top wall, a receiving part receiving the shell part is formed. After loosening the cover part from the bottom part, the jacket part can be transferred from the storage position by unfolding into the position of use. In this embodiment, the lid part serves, for example, to protect the casing part in the storage state of the packaging container.

It is preferred if, in the position of use of the casing part, the cover part is detachably mounted on the casing part so as to define a use state of the packaging container. This gives the lid part an additional function. The cover part can be placed on the position of use engaging shell part to complete the packaging space on top and thereby protect it received packaged.

In the receiving space can be stored in addition to the shell part further packaging material, such as corrugated cardboard receptacles, packaging container, even flattened, foils, foam, etc. This packaging material can be used for packaging, aligning, picking and padding of packaged when the shell part occupies the position of use, especially the packaging container use state.

It is advantageous if at the bottom part projecting from the bottom wall and protruding on the cover part of the ceiling wall each have a group of first outer walls, at least a second outer wall and the cover part a second outer walls are set at the bottom part and if the at least one second outer wall of the bottom part a the first outer walls of the lid part and each of the second outer walls of the lid part externally overlap one of the first outer walls of the bottom part in the storage state of the packaging container. In such a packaging container, the outer walls of the bottom part and the ceiling part are divided into first outer walls and second outer walls. The outer walls of the bottom part and of the lid part can overlap mutually at least in the storage state of the packaging container, so that at least one end region of a first outer wall overlaps with a region of a second outer wall. The first outer walls of the bottom part are assigned to them overlapping second outer walls of the lid part, and at least one outer wall of the lid part is assigned to them at least a second outer wall of the bottom part. It has been found that a packaging container formed in this way is easy to close and to handle. At the same time, a secure fit of the lid part on the bottom part in the storage state can be ensured.

Preferably, no outer wall of the bottom part is arranged on a side edge of the bottom part, along which the first side wall of the shell part extends in its position of use. This facilitates a user access to the skirt portion to transfer it from the stocking position to the use position.

It is favorable when between at least two outer walls of the bottom part in the circumferential direction of the bottom wall, the at least one outer wall of the bottom part is arranged and if between each two first outer walls of the cover part in the circumferential direction of the ceiling wall, a second outer wall of the lid part is arranged. In this way, both on the bottom part and on the Lid each alternately arranged first outer walls and second outer walls. This allows outer walls of the bottom part alternately overlap outer walls of the lid part or be overlapped by these. It has been found that such a packaging container can be closed in a still more reliable manner.

It is advantageous if, in the storage state of the packaging container, each of the first outer walls of the bottom part abuts flat on one of the second outer walls of the lid part and / or at least one of the first outer walls of the lid part bears against the at least one second outer wall of the bottom part. This makes it possible to reliably seal the receiving space defined by the cover part and the bottom part. The risk is reduced that undesirable dirt penetrates into the receiving space between the abutting outer walls of the bottom part and the lid part. As a result, the jacket part is stored particularly reliable.

Preferably, the first outer walls of the bottom part are each formed higher than the at least one second outer wall of the bottom part and / or the first outer walls of the lid part are each formed higher than the second outer walls of the lid part. This makes it possible to put the lid part in a simpler manner on the bottom part.

Advantageously, in the storage state of the packaging container, each of the first outer walls of the bottom part with a free edge facing away from the bottom wall on the ceiling wall and each of the first outer walls of the lid part with a free edge facing away from the ceiling wall on the bottom wall. The first outer walls of the bottom part and the lid part can form in this way a frame which surrounds the receiving space, which is bounded above by the top wall and bottom side by the bottom wall and in which the storage position engaging shell portion is arranged. In addition, the lid part may be supported with the first side walls on the bottom wall, and the bottom part may support the lid part with the first side walls. The packaging container This results in a robust and durable design. Even a plurality of packaging containers, each occupying the storage state, may be stacked one on top of the other.

In a structurally simple manner, the aforementioned embodiment can be implemented when the first outer walls of the bottom part are each formed the same height as the first outer walls of the lid part.

It can be provided that the at least one second outer wall of the bottom part are formed the same height as the second outer walls of the lid part, in which case preferably, as mentioned above, the first outer walls of the bottom part and the first outer walls of the lid part are each formed the same height. Thereby, there is the possibility that a first outer wall of the lid part is overlapped by the at least one second outer wall of the bottom part to the same extent as the first outer walls of the bottom part of the second outer walls of the lid part. Bottom part and lid part of the packaging container are thus to a certain extent "equivalent" designed.

Preferably, at least one of the first outer walls of the bottom part is connected to the at least one second outer wall of the bottom part and / or each of the first outer walls of the lid part is connected to at least one of the second outer walls of the lid part. This gives the bottom part and / or the lid part a more robust construction.

It is advantageous if at least one outside or inside on at least one, preferably both, the first outer walls of the bottom part fixed tab is held on the at least one second outer wall of the bottom part and / or if at each of the second outer walls of the lid part at least one outside or on the inside at one, preferably both, the first outer walls of the lid part fixed tab is held. The respective outer walls of the bottom part or the cover part can be connected to each other by means of the tabs in a structurally simple manner. The Connection can be done, for example, by gluing, but it is also possible to interlock.

It is advantageous if the at least one second outer wall of the bottom part has a free edge facing away from the bottom wall, which rests in the storage state of the packaging container on a tab at least a second outer wall of the lid part and / or if at least one of the second outer walls of the lid part facing away from the ceiling wall has free edge, which rests in the storage state of the packaging container on a tab of the at least one second outer wall of the bottom part. In this way, the lid part and the bottom part can be effectively supported against each other. This mutual support is preferably used in addition to the support already described above on the respective first outer walls of the cover part and the bottom part for use. Such a packaging container is designed to be particularly robust and load-bearing, and it is particularly possible to stack a plurality of such packaging container without damage to each other. The at least one second outer wall of the bottom part can abut, for example, two tabs, one tab each of the second side walls of the lid part and vice versa.

It is of advantage if a free edge facing away from the bottom wall of each of the first outer walls of the bottom part drops in the direction of the at least one second outer wall of the bottom part and / or if a free edge facing away from the top wall of each of the first outer walls of the lid part in the direction of the second outer walls of the Cover part drops. The free edges of the first outer walls of the bottom part and / or the cover part may have, for example, a chamfer in the direction of the respective second outer walls. This proves advantageous when placing the cover part on the bottom part, so that the packaging container can be handled in a simpler manner.

Preferably, the length of the shell part in the use position along a first spatial direction is equal to the distance of the first outer walls of the bottom part one another and / or the width of the casing part in the use position along a second spatial direction aligned perpendicular to the first spatial direction is equal to the distance of the first outer walls of the lid part from each other. The shell part can be used in the use position in this way without play between the first outer walls of the bottom part and / or the cover part, along the first spatial direction and the second spatial direction. The packaging container is reliably closed on the bottom side and / or top side in this way.

Preferably, the bottom part and / or the cover part and / or the shell part are made of a one-piece material blank. The packaging container can be manufactured inexpensively in this way. It can be provided in particular that the bottom part and / or the cover part and / or the shell part can be erected for use from the material blank and flat again after use as a material blank.

Advantageously, the bottom part and / or the lid part and / or the casing part are made of a paper material, in particular of corrugated cardboard. The packaging container can be produced in this way inexpensively and with low weight.

In a production of the bottom part and / or the cover part and / or the casing part of corrugated cardboard, it is advantageous if the wave crests of the paper wave for the first outer walls of the bottom part and / or for the first outer walls of the lid part and / or for the side walls of the Shell part in the position of use coming to use corrugated board are aligned perpendicular to a plane defined by the bottom wall or the ceiling wall. Transverse to the direction of the wave crests, ie present parallel to the bottom wall and / or the ceiling wall, the respective first outer walls and the side walls are thus formed particularly rigid. As a result, they can absorb high forces in the vertical direction, so that the packaging container has a very robust construction.

It can be provided that the casing part can be transferred again from the position of use into the storage position. This makes it possible to save the packaging container after transporting packaged goods again to save space.

The drawing shows a packaging container according to the invention, shown generally by the reference numeral 10, which comprises a bottom part 12, a cover part 14, a casing part 16 and a pallet 18. The bottom part 12, the cover part 14 and the shell part 16 are each made of a one-piece material blank made of a paper material, in particular corrugated cardboard. In contrast, the pallet 18 is made of wood. Deviating from the presently specially designed pallet 18, however, a so-called standardized "Euro pallet" with sliding boards can also be used.

The bottom part 12 comprises a rectangular bottom wall 20 with two opposite longitudinal sides and two opposite transverse sides. On one of the longitudinal sides and on both transverse sides, a total of three outer walls of the bottom part 12 are fixed, namely two outer walls designated as first outer walls 22 and 24 on the transverse sides and a second outer wall 26 designated outer wall on the longitudinal side. At the designated with a separate reference numeral 28 longitudinal side of the bottom wall 20, however, lacks a second outer wall ( Figures 2 and 3 ).

The outer walls 22, 24 and 26 are upstanding from the bottom wall 20, being folded from the original material blank relative thereto. Folding tabs on the outer wall 26 at the end sides of one of the bottom wall 20 defined bottom surface protrude laterally, are folded relative to the outer wall 26 and are outside on the outer walls 22 and 24 at. Of these, only one folding tab 30 is shown, which bears against the outer wall 22. A folding tab, not shown, abuts the outer wall 24 in a corresponding manner. With the outer walls 22 and 24, the folding tab 30 and the other folding tab are connected, for example by gluing or stapling.

The outer walls 22 and 24 have each emerged from an originally rectangular section of material whose bottom wall 20 facing away from the corner regions were separated triangular. The bottom wall 20 facing away from free edges 32 and 34 of the outer walls 22 and 24 fall in this way each in the direction of the outer wall 26 obliquely from until they are on a bottom wall 20 facing away from the free edge 36 thereof. The free edge 36 extends from the folding tab 30 to the other folding flap, not shown. In the direction of the longitudinal side 28, the free edges 32 and 34 fall obliquely down to the bottom wall 20.

The heights of the outer walls 22 and 24 and the outer wall 26 are dimensioned so that the free edges 32 and 34 are spaced from the bottom wall 20 in their central portions twice as far as the free edge 36th

The cover part 14 comprises a rectangular ceiling wall 38 whose dimensions are identical to those of the bottom wall 20 and which comprises two opposite longitudinal sides and two opposite transverse sides. On the longitudinal sides and the transverse sides, a total of four outer walls of the cover part 12 are fixed, namely at the longitudinal sides two outer walls 40 and 42 designated outer walls and at the transverse sides two outer walls 44 and 46 designated outer walls defined.

The outer walls 40, 42, 44 and 46 are folded from the plane of the material blank with respect to the top wall 38, from which they protrude vertically. Folding tabs 48 and 50, which protrude at the end sides of the second outer wall 44 over the ceiling surface defined by the ceiling wall 38, are folded over with respect to the second outer wall 44 and externally connected to the outer walls 40 and 42, respectively. The connection is made for example by gluing or stapling. In a corresponding manner, folding tabs 52 and 54 at the end sides of the second outer wall 46, which project beyond the ceiling surface, folded over with respect to the second outer wall 46 and externally connected to the outer walls 40 and 42, respectively. The folding tabs 50 and 54 are in FIG. 1 to see.

The first outer walls 40 and 42 have each emerged from an originally rectangular shaped material section, whose corners facing away from the top wall 38 have each been separated triangularly. As a result, the free walls 56 and 58 of the outer walls 40 and 42 facing away from the ceiling wall 38 each slope obliquely in the direction of the outer walls 44 and 46. The outer walls 44 and 46 facing away from the top wall 38 free edges 60 and 62, which extend from the folding tabs 48 to 50 and 52 to 54, respectively.

The heights of the first outer walls 40 and 42 in the region of their central portions are dimensioned so that the free edges 56 and 58 are spaced twice as far from the ceiling wall 38 as the free edges 60 and 62 of the outer walls 44 and 46th

Further, the distance of the free edges 56 and 58 from the ceiling wall 38 is identical to the distance of the free edges 32 and 34 of the bottom wall 20. Thus, the second outer walls 44 and 46 are formed the same height as the second outer wall 26th

The packaging container 10 may have a in FIG. 1 assume stored state in which the lid part 14 is detachably mounted on the bottom part 12. In the storage state, the first outer walls 22 and 24 of the bottom part 12 in their free end regions on the outside of the second Outer walls 44 and 46 of the cover part 14 overlapped, ie partially overlapped. Furthermore, the first outer wall 40 of the cover part 14 is overlapped on the outside by the second outer wall 26 of the base part 12 in its free end region, ie it overlaps in regions. The outer walls 22 and 44, 24 and 46 and 26 and 40 lie flat against each other in the overlapping areas. The cover part can also be rotated by 180 ° placed on the bottom part 12, wherein the outer walls 26 and 42, 22 and 46 and 24 and 44 abut each other.

Due to the dimensions of the outer walls 22, 24, 40 and 42, the free edges 32 and 34 abut the ceiling wall 38, and the free edges 56 and 58 abut against the bottom wall 20. Further, the free edge 36 of the outer wall 26 is located on the free edge 60 of the outer wall 44, in the region of the folding tabs 30 and 48. In a similar manner, the free edge 36 is located on the free edge 62 of the outer wall 46, in the region of Folding tab 52 and the folding tab, not shown.

In this way, the bottom part 12 and the lid part 14 effectively against each other, and it is particularly possible to stack a plurality of packaging containers 10 without damage to each other. Due to the flat concerns of each associated outer walls in the overlapping areas defined between the bottom wall 20 and the top wall 38 in the storage state of the packaging container 10 receiving space 64 is effectively protected against ingress of dirt.

In the storage state 10, the foldable casing part 16 is received in the receiving space 64, wherein it occupies a storage position explained below. Starting from the storage position, the shell part 16 as also explained below by unfolding in a in the FIGS. 8 and 9 shown used position to transfer the packaging container 10 in a state of use.

As in particular from the FIGS. 4 and 5 becomes clear, the casing part 16 is a self-contained material strip 66 with in the unfolded position of use cuboid outer contour. The shell part 16 comprises a first rectangular longitudinal side wall 68 and a second longitudinal side wall 70 opposite thereto. The longitudinal side walls 68 and 70 are connected to one another by means of a first transverse side wall 72 and a second transverse side wall 74 arranged opposite thereto. The transverse side wall 72 is foldable relative to the longitudinal side walls 68 and 70 about common edges 76 and 77, respectively. The transverse side wall 74 is foldable relative to the longitudinal side walls 68 and 70 about common edges 78 and 79, respectively.

The transverse side wall 72 is additionally foldable along a side wall fold line 80 extending centrally between the edges 76 and 77 and parallel thereto. Similarly, the transverse side wall 74 is additionally foldable in itself about a center between the edges 78 and 79 and parallel thereto Sidewall fold line 81.

At their lower, the bottom wall 20 in the use position of the shell portion 16 facing edges, the side walls 68, 70, 72 and 74 edges 82, 84, 86 and 88, respectively. Edges 82, 84, 86, and 88 define fold lines 83, 85, 87, and 89, respectively, in the planes defined by sidewalls 68, 70, 72, and 74, respectively.

The casing part 16 comprises a fastening member in the form of a retaining tab 90, by means of which it is fixed on the bottom wall 20. The retaining tab 90 is integrally connected along the edge 82 with the longitudinal side wall 68 and foldable relative to this around the fold line 83.

The retaining tab 90 comprises a connecting portion 92 adjacent to the longitudinal side wall 68 along the edge 82 and a fastening portion 94. The fastening portion 94 is foldably connected to the connecting portion 92 along a fold line 96 parallel to the fold line 83 and forms the portion of the retaining tab facing away from the longitudinal side wall 68 90th By means of the attachment portion 94, the shell portion 16 is fixed to the bottom wall 20, for example by gluing or stapling. But it can also be provided that the attachment portion 94 is stitched through the bottom wall 20 through with the pallet 18, so that a separate attachment of the bottom wall 20 on the pallet 18 can be omitted.

The attachment portion 94 is fixed on the bottom wall 20 parallel to the longitudinal side 28 and close thereto. Of the longitudinal side 28, the attachment portion 94 at a distance which is substantially equal to the width of the connecting portion 92 and thus the distance of the fold lines 83 and 96 from each other. More precisely, the distance of the attachment portion 94 from the side edge of the bottom wall 20 at the longitudinal side 28 of the width of the connecting portion 92 plus the wall thicknesses of the longitudinal side wall 68 and the outer wall 42nd

The connecting portion 92 is divided along the edge 82 into three segments, so that in the connecting portion 92, two openings 98 and 100 are present. The openings 98 and 100 are arranged symmetrically relative to each other with respect to a plane of symmetry oriented perpendicular to the bottom wall 20 and dividing the longitudinal side wall 68 centrally at the connecting section 92. They serve to receive the locking tabs of the casing part 16, which are mentioned below, in their storage position.

At the edge 84 of the second longitudinal side wall 70, a foldable foldable flap 102 foldable around the edge 84 defined by the edge 84 is fixed integrally to the longitudinal side wall 70. The folding tab 102 extends along the entire edge 84.

In extension of the folding tab 102 on the fold line 85 addition, two locking tabs 104 and 106 are indirectly held on the longitudinal side wall 70 on the longitudinal side wall 70, via the folding tab 102 from which they protrude. If the folding tab 102 relative to the longitudinal side wall 70 around the fold line 85, this also leads to the folding of the locking tabs 104 and 106 relative to the longitudinal side wall 70, but in the opposite direction, because they are arranged on the fold line 85 opposite side of the folding tab 102.

Along the edge 84, the locking tabs 104 and 106 are arranged so that they are exactly opposite the openings 98 and 100, respectively. Here, the locking tab 104 of the opening 98 is assigned and the locking tab 106 of the opening 100th

The locking tabs 104 and 106 are also assigned to a lower edge of the outer wall 26 arranged slot-shaped receptacles 108 and 110, respectively. In the receptacles 108 and 110, the locking tabs 104 and 106 engage in the position of use of the shell portion 16.

Along the edge 86, on the transverse side wall 72, a folding flap 87 foldable around the edge 86 defined by the edge 86 is likewise connected in one piece with the transverse side wall 72. In extension of the folding tab 112 beyond the edge 86, a locking tab 114 is indirectly held on the transverse side wall 72 on the transverse side wall 72, via the folding tab 112, from which it protrudes. The locking tab 114 is disposed on the folding tab 112 opposite side of the fold line 87. If the folding tab 112 is folded about the fold line 87 relative to the transverse side wall 72, this also leads to folding of the locking tab 114 about the folding line 87, but in the opposite direction.

The locking tab 114 is located centrally on the edge 86, extending transversely across the sidewall fold line 80 of the transverse sidewall 72. With respect to the Seitenwandfaltlinie 80, it is formed symmetrically in itself. In the storage state of the casing part 16, the locking tab 114 is associated with the opening 98 in the connection section 92.

In the use position of the casing part 16 of the locking tab 114 is associated with a centrally disposed on a lower edge of the outer wall 22 slot-shaped receptacle 116, into which the locking tab 114 can engage.

A folding tab 118 is integrally connected along the edge 88 with the transverse side wall 74 and foldable relative to this fold line 89 defined by the edge 88. In extension of the folding tab 118, a locking tab 120 is held indirectly on the transverse side wall 74, via the folding tab 118, from which it protrudes. The locking tab 120 is disposed on the folding line 89 opposite side of the folding tab 118. If the folding tab 118 is folded about the fold line 89 with respect to the transverse side wall 74, the locking tab 120 is folded with respect to this, but in the opposite direction.

The locking tab 120 is located centrally on the edge 88 and extends transversely across the sidewall fold line 81 relative to which the locking tab 120 is symmetrically disposed.

In the storage position of the casing part 16, the locking tab 120 is associated with the opening 100. In the use position of the casing part 16 of the locking tab 120 is associated with a receptacle 122 which is disposed on a lower, the bottom wall 20 facing edge of the outer wall 26.

As mentioned, the shell part 16 is fixed by means of the attachment portion 94 on the bottom wall 20. Takes the shell part 16 as in the Figures 2 and 3 For example, when the supply position is shown, the connection portion 92 is folded relative to the attachment portion 94 and oriented approximately at right angles thereto. The longitudinal side wall 68 is folded relative to the connecting portion 92 and extends parallel and spaced from the bottom wall 20, the distance corresponding to the width of the connecting portion 92.

The shell part 16 is folded in the storage position and essentially flattened, wherein the longitudinal side wall 70 is arranged opposite the longitudinal side wall 68 and rests flat on the bottom wall 20. The folding tab 102 is folded relative to the longitudinal side wall 70 about the folding line 85 in such a way that it rests flat against the longitudinal side wall 70 on the inside facing away from the bottom wall 20. As a result, the locking tabs 104 and 106 protrude in an extension from the side wall 70 and engage in a fixed manner in the openings 98 and 100, respectively, of the connecting section 92.

The lateral side wall 72 is folded relative to the longitudinal side walls 68 and 70 at fold lines defined by the edges 76 and 77, respectively. In addition, the lateral sidewall 72 is folded inwardly along the sidewall fold line 80.

The folding tab 112 is folded with respect to the transverse side wall 72 about the fold line 87 and lies flat against the inner wall facing away from the outer wall 22. The locking tab 114 is in extension of the transverse side wall 72 from. The folding tab 112 and the locking tab 114 are also folded inwardly about the sidewall fold line 80. The locking tab 114 can engage in this manner folded into the opening 98 of the connecting portion 92, wherein it is disposed above the locking tab 104.

In a corresponding manner, the transverse side wall 74 is folded relative to the longitudinal side walls 68 and 70 by fold lines defined by the edges 78 and 79. In addition, the transverse side wall 74 is folded in itself about the Seitenwandfaltlinie 81, as well as the folding tab 118 and the locking tab 120. The folding tab 118 lies flat on an outer wall 24 facing away from the inner side of the transverse side wall 74, from which the locking tab 120 protrudes in extension. The locking tab 120 engages in the opening 100 of the connecting portion 92 and is arranged above the locking tab 106.

In the storage position, the casing part 16 is stored in a space-saving manner in the receiving space 64 and is protected against external influences and in particular dirt in the packaging container 10 occupying the storage state.

The packaging container 10 can be transferred under unfolding of the shell part 16 in a position of use in a state of use. For this purpose, first the cover part 16 is to be detached from the bottom part 12 ( FIG. 2 ).

Subsequently, the casing part 16 is pivoted about the folding line 96 relative to the fixed to the bottom wall 20 mounting portion 94 and thereby unfolded by increasing the distance from the bottom wall 20 ( FIG. 6 ). The shell portion 16 can be pivoted so far until the longitudinal side wall 68 is oriented relative to the bottom wall 20 at right angles or substantially at right angles. If the connecting portion 92 is still slightly inclined with respect to the bottom wall and is not yet at this, snap the locking tabs 104, 106, 114 and 120 independently from the openings 98 and 100 of the connecting portion 92 out. Under the weight of the shell portion 16, the connecting portion 92 then contacts the bottom wall 20.

Subsequently, the jacket part 16 can to a certain extent be pulled apart "like an accordion", with the longitudinal side wall 70 being moved in the direction of the outer wall 26 ( FIG. 7 ). This results in that also the transverse side walls 72 and 74 are unfolded, both in itself and with respect to the side walls 68 and 70. The shell portion 16 can be unfolded until the longitudinal side wall 70, the outer wall 26, the transverse side wall 72, the outer wall 22 and the transverse side wall 74, the outer wall 24 contact surface.

For the final transfer of the shell part 16 in the position of use, the folding tabs 102, 112 and 118 are folded around the fold lines 85, 87 and 89, respectively, until they rest flat on the bottom wall 20. This leads to, that the locking tabs 104 and 106 are also folded about the fold line 85 and can engage in the receptacles 108 and 110 on the second outer wall 26. In a corresponding manner, the locking tab 114 is folded around the fold line 87 and can engage in the receptacle 116 on the outer wall 22. In a further corresponding manner, the locking tab 120 is folded about the fold line 89 and can engage in the receptacle 122 on the outer wall 24.

The casing part 16 then takes in the FIGS. 8 and 9 shown use position in which it rests dimensionally stable on the bottom wall 20 and a shell 124 of the packaging container 10 is formed. The locking tabs 104, 106, 114 and 120 form for this purpose locking members for fixing the jacket 124 on the bottom part 12 from.

The jacket 124 and the bottom wall 20 grasp a packaging space 126 laterally and at the bottom, which can then be filled with packaged goods. In order to make it easier for a user to fill the packaging space 126 with packaged goods, a flap 128 is integrated into the longitudinal side wall 70 ( FIG. 8 ). The flap 128 may be folded outwardly about a fold line 130 to facilitate engagement of the user in the packaging space 126.

The locking tabs 104, 106, 114 and 120 each engage both perpendicular to the bottom wall 20 and parallel to the bottom wall 20 without play in the receptacles 108, 110, 116 and 122 a. In the use position, the jacket part 16 is therefore secured against slipping relative to the bottom part and also against loosening in the vertical direction.

Next, the locking tabs 114 and 120 are aligned in the position of use of the shell portion 16 perpendicular to the transverse side walls 72 and 74, respectively. Further, as they extend beyond the sidewall fold lines 80 and 81, they stabilize the transverse sidewalls 72 and 74. This results in undesirable folding back of the sidewalls 72 and 74 about them Side wall fold lines 80 and 81 can be prevented, the shell part 16 in the position of use is therefore very dimensionally stable.

The length of the unfolded casing part 16 is dimensioned so that the transverse side walls 72 and 74, as mentioned, can lie flat against the outer walls 22 and 24, which further increases the stability of the casing part 16 in the position of use. In the transverse direction, the jacket part 16 is dimensioned such that its width corresponds to the distance of the outer walls 44 and 46 of the cover part 14 from each other. For this reason, the cover part 14 can be placed without clearance on the casing part 16 occupying the position of use in order to cover the packaging space 126 at the top ( FIG. 9 ). The packaging container 10 then assumes a use state in which packaged goods received in the packaging space 126 are protected. It may be provided that in the storage state, packaging materials, such as packaging containers, also laid flat, corrugated cardboard receptacles, foils, foams or the like, are accommodated in addition to the casing part 16 in the receiving space 64, with which packaged goods can be packed, upholstered, aligned etc. in use.

It is possible to transfer the packaging container 10 from the use state to the storage state. Conversely, the procedure is as described above.

The packaging container 10 according to the invention can be handled in a simple and user-friendly manner. Even with relatively large dimensions, for example, a bottom surface of the bottom part 12 of about 180 cm x about 120 cm is a one-man operation for transferring the storage state in the use state and vice versa possible.
