Description

The invention relates to a folding box consisting of a cover and a preferably cuboid inner body.

Such a folding box can be unfolded from a folded, flat state into a 3-dimensional, overall cuboid shape. Both the cover and the cube-shaped inner body in the unfolded state consist of corresponding folding blanks, i.e. of a corresponding plurality of suitable folding elements or sections that can be pivoted or folded relative to one another, so that a change between the folded and the unfolded form is possible.

A folding box of the type described at the outset ultimately consists of two central box parts, namely the cover on the one hand and the cuboid inner body on the other. In folding boxes of this type, which are used in particular for packaging high-quality, expensive products, the cover runs around four sides of the box. In the interior of this quasi-hollow, four-sided folding cover, the inner body is arranged, in which the packaged goods are received. In order to fix the cover in the unfolded position so that it is prevented from unfolding unintentionally, a known folding box, such as for example in FIG EP 3 257 769 A1 described, a magnetic clasp is provided on the cover. In the unfolded position, two folding elements of the cover lie flat on top of each other, with magnetically interacting magnetic elements being provided in both folding elements, which magnetically adhere to each other in the unfolded position, so that the two folding elements can only be detached from one another with a slight effort, but do not open automatically. These magnetic elements are to be concealed for optical reasons in particular, for which purpose they are arranged under a paper support covering the relatively stiff binding material, mostly cardboard or the like. On the one hand, the integration of these magnetic elements in the production process of the cover or the case box is complex, on the other hand, a suitable number of folding elements on the part of the cover is a corresponding one To ensure element coverage. Come as in EP 3 257 769 A1 alternatively provided that snap fasteners or Velcro fasteners are used as fastening elements, the same applies because these fastening elements are also correspondingly complex to integrate, as is a correspondingly large-area cover design.

The invention is therefore based on the problem of specifying a folding box which is improved over this.

1. a) der faltbare Einband aus vier in Reihe angeordneten und schwenkbar verbundenen Faltelementen, nämlich einem Bodenelement, einem Seitenelement, einem Deckelelement und einem weiteren Seitenelement, besteht,
2. b) und der aus einer zusammengefalteten flachen Form in eine aufgefaltete Quaderform bringbare, faltbare Innenkorpus mindestens aus vier Seitenwänden besteht,
3. c) wobei der Innenkorpus auf dem Bodenelement des Einbands befestigt ist und in der Schließstellung des Einbands dessen Seitenelemente benachbart zu Seitenwänden des Innenkorpus verlaufen und das Deckelement die offene Seite des Innenkorpus schließt,
4. d) und wobei eine an der freien Seite des endständigen Seitenelements angeordnete Einstecklasche in einen Einsteckschlitz zwischen dem Bodenelement und dem Innenkorpus zum Fixieren des Einbands in der Schließstellung einsteckbar ist.

To solve this problem, a folding box is provided according to the invention, consisting of a cover and a cuboid inner body, wherein

1. a) the foldable cover consists of four folding elements arranged in a row and pivotably connected, namely a base element, a side element, a cover element and a further side element,
2. b) and the foldable inner body, which can be brought from a folded flat shape into an unfolded cuboid shape, consists of at least four side walls,
3. c) wherein the inner body is fastened to the bottom element of the cover and, in the closed position of the cover, the side elements of the cover run adjacent to the side walls of the inner body and the cover element closes the open side of the inner body,
4. d) and wherein an insertion tab arranged on the free side of the terminal side element can be inserted into an insertion slot between the base element and the inner body for fixing the cover in the closed position.

As described, the folding box consists of a foldable cover and a foldable inner body, which is cuboid in the unfolded state, which makes it possible to fold the folding box in a small format and thus save space when not in use. According to the invention, the foldable cover consists of only four pivotable ones arranged in a row connected folding elements, namely a bottom element, a side element, a cover element and a further side element. On or in the area of the free edge of the terminal further side element, a tuck-in flap is provided which, unlike in folding boxes of this type, can be inserted into a tuck-in slot, via which the cover is fixed in its unfolded position.

This insertion slot is formed between the surface of the base element and the inner body which is arranged on the base element. The foldable inner body, which in turn consists of at least four side walls and which, in a further development of the invention, for example, can consist of at least five pivotably connected folding elements, namely a base and side walls arranged on its four sides, is placed on the cover-side base element as part of the production of the folding box placed on and fixed to it, usually glued. Since the base area of the inner body, e.g. defined via the area of its possibly provided floor, almost corresponds to the area of the floor element, a suitable slot can now be formed according to the invention between the inner body and the floor element surface, e.g. between the floor and the floor element, that is for example an area in which the two opposite floor surfaces are not glued together. This slot, which is of course formed in the area of a box edge, is used to receive the push-in flap. To unfold it is therefore only necessary to unfold the inner body together with the cover and place the cover with its cover element on the open inner body and bring the end further side element into the closed position in which it runs adjacent to a side wall of the inner body and thereby to push the tuck-in flap into the tuck-in slot.

The folding box according to the invention is characterized by its simplicity. On the one hand, the binding consists of only four folding elements, since, unlike in the prior art, no element overlap is required due to the closure device provided according to the invention with the tuck-in flap. This means that the binding can be produced in a fundamentally simpler and therefore more cost-effective manner can, especially since no two interacting closure elements such as magnetic strips, snap fasteners or the like are to be provided, but only a tuck-in flap, which can be formed in a suitable manner as an integral folding section at the edge of the binding, or as a folding element attached to it, i.e. preferably glued on.

The construction of the insertion slot is also very simple, since this is done simply by gluing the inner body or, if provided, its base to the base element not circumferentially on all connecting sides, but only locally on the insertion side, so that at the position at which the insertion tab is to be inserted, a corresponding insertion slot is realized due to the lack of an adhesive connection. Of course, there is also the possibility of forming two or more tuck-in flaps on the edge of the cover, in a corresponding manner several tuck-in slots or a large tuck-in slot resulting over a corresponding length in the edge area are then to be realized.

Thus, the case according to the invention offers the possibility of a simple, less material with regard to the binding production in particular and therefore cost-effective production with the possibility of being able to unfold it as desired between a small, space-saving form and the erected form.

It is conceivable that the inner body consists of at least five pivotably connected folding elements, namely a base and side walls arranged on its four sides. A complete inner body component is provided here, which can be prefabricated as such and is glued with its base onto the base element. Alternatively, it can be provided that the inner body consists of four separate side walls and a separate base, all of which are fastened separately to the base element, that is to say are glued on. So here several separate elements are used to form the inner body.

If an inner body is provided with a base and side walls hinged to it, the base is expediently glued to the base element, by which the entire inner body is fixed. If separate side walls and a separate base are used, both the four separate side walls are glued to the base element via adhesive tabs provided thereon, and the base is also glued to the side tabs and the base element. The side walls, as simple punched blanks, therefore have adhesive flaps by means of which they are glued to the floor element. The separate floor is then glued onto the floor element, thereby covering the adhesive flaps.

It is useful if the two opposite side edges of the base or the two separate side walls are spaced apart from the adjacent side edge of the base element by at least the thickness of an adjacent side wall element of the cover. This means that the base or the separate side walls is somewhat narrower than the base element in at least one direction, namely in total at least by twice the thickness of a side wall element. This enables the two bottom side edges of the inner carcass to slide slightly inward with respect to the adjacent side edges of the side elements of the cover, so that in the unfolded state the cover-side side elements run parallel and flat, or at a minimal distance from the carcass-side side walls. Overall, the result is a very compact structure without larger or noticeable side slits. In addition, this ensures that the cover can be placed around the inner body virtually without tension, since their sizes are precisely matched to one another. This makes it possible to insert the tuck-in flap without tension, since all of the folding elements of the cover and the body lie on top of one another without tension.

If the cover is closed, the result is a cuboid shape which is closed on four sides, namely the base, cover and the two mutually opposite side walls, while the other two sides, which run orthogonally thereto, are open. This binding therefore shows a visually appealing, symmetrical appearance in which all the folding elements of the Covers merge into one another virtually seamlessly and, in particular, the adjacent side edges of the side elements are almost flush or are adjacent to one another without any gaps. This sometimes means that it is not immediately apparent to the user on which side the cover is to be opened, since all pages are more or less closed and present themselves as closed areas. In order to simplify opening, an advantageous further development of the invention provides that at least one grippable opening means for manually releasing the side element from the closed position fixed via the insertion tab is provided on the side element having the insertion tab. This means that the side element, which is to be swiveled open for opening, is more or less visually identified via a suitable opening means, and the manually grippable opening means enables the side element to be easily detached and thus the cover to be opened.

The opening means can preferably be designed in the form of a grip tab protruding from the side element. On the one hand, a grip tab of this type can be visually grasped immediately, and on the other hand, it is easy to grip so that the side element can be swiveled open without any problems. The grip tab can be part of a tab blank which also includes the push-in tab and which is attached to the side element. This means that both the tuck-in tab and the grip tab are formed over this tab blank. This tab blank is expediently formed from two blanks glued to one another, which tab blank is glued to the side element, possibly laminated with a paper layer. If the tuck-in flap is a one-piece element of the cover case blank, the grip tab is of course formed via a separate, separate flap blank that is glued to the cover side element.

As an alternative to designing the opening means in the form of a grip tab, it is also conceivable to design the opening means as an engagement opening, i.e. as a simple punched opening, for example in the form of a circular hole in the side element, which engagement opening is formed near the side element edge having the tuck-in flap. The user can easily On the one hand, recognize the page to be opened and, on the other hand, reach into the opening with your finger and swing open the cover page.

As an alternative or in addition, it is also conceivable that the two free corners of the side wall element having the plug-in tab are chamfered or rounded. This also makes it possible both to recognize the cover page to be opened and to enable it to be opened in a simple manner. Because the two beveled or rounded corners are easily recognizable. In addition, these recessed areas can easily be attacked manually in order to swing open the side element. The formation of a grip tab or the like is then not absolutely necessary, but can also be provided in addition.

As already described, the bottom or the separate side walls are fixed to the bottom element via the adhesive flaps and the separate bottom is expediently fixed via an adhesive connection, which adhesive connection extends only in sections along the edge-near area to be glued to form the insertion slot on the insertion side. This means that the adhesive is only applied locally on this insertion side; if there is only one insertion tab provided in the middle of the cover side edge, the adhesive connection is cut out in the central area so that the slot is formed. Of course, the gluing takes place on all other circumferential edges or otherwise also over a large area over the entire floor area. Alternatively, it is also conceivable that a recess is formed on the base element, which is overlapped by the base, whether with hinged side walls or separately, or the adhesive flap of the separate side wall to form the insertion slot. Here, the base element is either embossed with the recess, or it has a cutout which is overlapped and closed on the outside by a cover layer. The slot results on the inside after the recess there is overlapped by the bottom or the adhesive flap.

As described, the inner body consists of at least five folding elements, namely a base and four pivotably articulated on the four base edges Sidewalls. To stiffen the inner body in the unfolded position, it is useful in a further development of the invention if a stiffening wall is pivotably arranged on two opposite side walls of the inner body, which can be pivoted on the inside of the respective side wall when the inner body is set up. In this case, the folding blank of the inner body consists of seven folding elements, namely the five folding elements mentioned at the beginning and the two additional stiffening walls. If the folding box is consequently unfolded, after the inner body has been erected, the respective side wall needs to be pivoted inward and pivoted onto the respective side wall, so that the stiffening results. In order to permanently fix this pivoted position, it is advantageous if at least one fixing element, in particular a locking projection, is provided on the free longitudinal edge of each stiffening wall, which engages in a fixing recess, in particular a locking recess, on the floor to fix the pivoted stiffening wall. Such a fixing element, in particular in the form of a latching projection, can be designed as a folding section in a simple manner, just as the fixing recess, ie in particular the latching recess, can easily be punched out when punching the folding blank. In any case, the respective stiffening wall is correspondingly fixed or latched in the restricted stiffening position, so that permanent stabilization is provided.

The four side walls of the inner body are expediently connected to one another via corresponding kinked corners, which are preferably formed on the two side walls not overlapped by a side element in the closed position, in particular glued of the inner body, the side walls are all automatically moved and unfolded and, when folded, are converted back into the flat shape.

The inner body can consist of a one-piece folding blank, that is to say that all at least five folding elements, possibly all of them, on the inner body seven folding elements, as well as the corresponding kinked corners are formed, which still have to be glued to the adjacent side walls as part of the production of the folding box. Alternatively, it is also conceivable that the inner body comprises a first folding blank, which comprises the bottom and the side walls that are pivotably connected to opposite sides and possibly the stiffening walls that are pivotably connected to them, and two second case blanks, which form the two further side walls along with hinged corners and with the bottom and the adjacent side walls are connected by hinged corners. Here the inner body would be formed from three folding blanks that are glued together.

The cover and / or the inner body itself is preferably made of cardboard or cardboard, the use of corrugated cardboard also being conceivable, in particular with regard to the inner body. It is therefore possible to cover the cover and / or the inner body, if necessary at least in sections, with a decorative paper or a decorative film, which decorative paper or which decorative film defines the external appearance and can be of virtually any design. However, not only the outside is expediently covered with a decorative paper or a decorative film, but also the inside, which can be seen when the cover or inner body is unfolded, so that there is also an appealing appearance.

Since the cover forms the exterior of the folding box, as it were, with the exception of the two open sides and can consequently be exposed to mechanical loads, it is useful if the cover has a higher rigidity than the inner body. This means that the cardboard or cardboard of the cover is correspondingly thicker, i.e. has a higher weight per unit area than the inner body.

The folding box as a whole can, as seen in the side view, have a rectangular shape, that is to say that the two side elements on one cover side are of the same size, as are the base element and the cover element. If the bottom element and the cover element have the same size as the side elements, this results a square shape, otherwise a rectangular shape. If the edge lengths of the respective elements are the same, a cube shape then results, and if the edge lengths of the respective side and longitudinal edges of the individual elements are unequal, then naturally a rectangular parallelepiped shape. The geometry of the inner body naturally corresponds to that of the binding, so that a corresponding cuboid shape that is closed on all sides results. Alternatively, there is also the possibility of deviating from the square or rectangular shape as seen in the side view. For this it is necessary that the two side elements of the cover (and of course also the side walls of the inner carcass) are of different heights, which means that the side elements are at right angles to the base element, as are the side walls on the carcass side at right angles to the floor. On the cover side, however, the cover element then runs at a corresponding angle to the base element or the side elements, that is, it is no longer parallel to the base or perpendicular to the side elements. Seen from the side, the result is a trapezoidal shape. In a corresponding manner, of course, the side walls of the inner body, which close the two open cover pages, are designed to be trapezoidal.

the Figs. 1 and 2 show a folding box 1 according to the invention, consisting of a cover 2 and a cuboid here in the unfolded form Inner body 3, with the Figs. 1 and 2 show the folding box 1 in the unfolded state. Fig. 1 shows the folding box 1 from the inside with a view of the inner body 3, Fig. 2 the outside facing the outside of the cover.

The foldable cover consists of, see Fig. 2 , of four folding elements arranged in a row and pivotally connected, namely a base element 4, a first side element 5, a cover element 6 and a second side element 7. On this, a push-in flap 9 is provided on its free longitudinal edge 8, as well as a grip tab 10. The cover 2 consists of a sufficiently rigid cardboard or cardboard, that is to say having a corresponding basis weight, and is provided with a decorative paper 11 on the inside and a decorative paper 12 is applied on the outside. The tuck-in flap 9 can be an integral part of the folding blank of the binding 2, that is to say an integral part of the cardboard or cardboard body. However, it can also be glued on as a separate folding blank and covered by the decorative paper 11. The grip bottle 10 is also a suitable folding blank, that is to say made of paper, but it can also be made of fabric or the like and is likewise glued on in a suitable manner and, if necessary, covered with the decorative paper 11.

The inner body 3, which is already minimally raised here, ie not lying completely flat, is preferably a one-piece folding blank, here consisting of a total of seven folding elements. It has a floor 13, two first side walls 14 pivotably articulated to the floor 13 and two articulated reinforcing walls 15 connected to these. Furthermore, two further side walls 16 are pivotably articulated to the two further, mutually opposite bottom side edges, which are coupled in terms of movement to the side walls 14 via corresponding kink corners 17, the kink corners 17 being glued to the side walls 14.

On the free edges of the stiffening walls 15, fixing elements 18 are formed in the form of two latching projections in each case, which are formed on the base 13 Fixing receptacles 19, that is to say corresponding snap-in receptacles, engage in the unfolded position, which will be discussed below.

The inner body 3 also consists of a corresponding folding blank made of cardboard or cardboard, but made of a somewhat thinner or a lower weight per unit area, since it does not necessarily have to be as stable as the cover 2, which is the outer cover. The body folding blank is also on both Pages with a decorative paper 23 (inside) or 24 (outside) covered in order to design its appearance accordingly.

Both the cover 2 and the inner body 3 are corresponding folding components consisting of the corresponding folding blanks, on which, without going into detail, corresponding folding edges are formed by suitable line embossing, which form pivot axes about which the individual folding elements can be pivoted.

the Figures 3-8 show the continuous erection process of the wrong box 1, starting from the flat shape according to FIG Fig. 1 .

Fig. 3 shows that the inner body 3 has already been partially set up. It can be seen that the two side walls 16 are already slightly folded up, and the two side walls 14 are coupled with them in terms of movement, since the movement coupling is provided via the kinked corners 17 as described. The stiffening walls 15 have not yet been driven in.

Fig. 4 shows the inner body 3 in a further unfolded position shortly before the moment at which the side walls 14, 16 are completely unfolded and run vertically to the floor 13. The two stiffening walls 15 are now also guided upwards and are pivoted inwards when the side walls 14, 16 are all folded up vertically on the floor 13, as Fig. 5 indicates. There the right stiffening wall 15 is already turned inwards, the left stiffening form 15 not yet. This is done in the next folding step. During this folding in, the fixing elements 18, that is to say the locking projections, snap into the corresponding ones Fixing receptacles 19, that is to say the punched-out latching receptacles, via which the stiffening walls 15 and thus this side wall construction, but also the entire inner body 3, are fixed in the unfolded shape.

In the next folding process, like the Figures 6 - 8 show the cover 2 folded around the inner body 3. It should first be noted that the floor 13, which is glued to the floor element 4, is somewhat smaller than the floor element 4, as in FIG Fig. 2 is shown where the bottom 13 is shown in phantom. This means that in the example shown there is a slight overhang of the single-volume base element 4 on all four edges. This makes it possible at the two longitudinal edges that the respective side element 5, 7 can be placed flat against the adjacent side wall 14 of the inner body 3 without tension, which means that the cover 2 can be easily folded over and closed. The distance between the two other, shorter edges of the base 13 and the base element 4, that is to say on the open cover pages, is provided here, but does not have to be implemented; a flush design would also be conceivable here.

Fig. 6 Now shows a perspective side view of the folding box 1 with the unfolded inner body 3 and the not yet unfolded cover 2. Shown there is the bottom element 4 on which the inner body 3 rests, followed by the first side element 5, the lid element 6 and the terminal second side element 7 with the tuck-in flap 9 and the grip tab 10, not shown in detail.

In the next step, the side element 5, the cover element 6 and the second side element 7 are then folded over so that the side element 5 lies parallel to the side wall 14 of the inner body 2 and the cover element 4 is placed on the inner body 3, which is open at the top. The end side element 7 is then in the last folding step, see Fig. 8 , folded down so that it comes to lie parallel to the side wall 14 on the body side, during which folding movement the tuck-in flap 9 is simultaneously inserted into an insertion slot 20. This is also in Fig. 9 shown in more detail. If the side element 7 is completely folded against the side wall 14, the push-in flap 9 becomes complete inserted into the insertion slot 20, via which the cover 2 is fixed in its closed position.

the Figures 10 and 11 show the structure in the area of the box bottom of the folding box 1, formed by the bottom element 4 and the bottom 13 of the inner body fixed by an adhesive layer 21. Fig. 10 shows the view as in Fig. 9 , but with the tuck-in flap 9 not inserted. The adhesive layer 21 shown here exaggeratedly thick does not extend over the entire width of the connection, but is recessed in the middle, so that the insertion slot 20 is formed due to the lack of a material connection. Of course, the adhesive layer 21 extends along the three other connecting edges, or full-surface gluing takes place; the adhesive layer 21 is only locally cut out in the front edge-side area in order to form the insertion slot 20. The push-in flap 9 is then pushed into this as described.

Fig. 11 shows the end position, the side element 7 being shown here only in dashed lines. It can be seen that the insertion tab 9 engages in the insertion slot 20, while the grip tab 10 protrudes slightly on the outside and can be gripped in order to pull the insertion tab 9 out of the insertion slot 20 and pivot the side element 7 open.

Also indicated by dashed lines is the possibility of providing the two corners 22 of the side element 7 with a rounding in order to mark the side of the box to be opened on the one hand, in addition to or as an alternative to the design of the grip tab 10, and on the other hand to mark the opening there make possible. This rounding is also in Fig. 2 already indicated by dashed lines.

The folding box 1 is folded in the opposite way, that is, first the cover 2 is opened and unfolded by pulling out the tuck-in flap 9, whereupon by folding out the reinforcing walls 15, which are provided with gripping tabs 25, over which they can be easily can be pivoted open, the inner body 3 is released again and collapsed.

Because the respective folding blanks of cover 2 and folding blank 3 are provided with decorative paper on the inside and outside, any design options arise, whereby a laminated decorative film can also be used instead of a decorative paper.

Finally, it should be noted that instead of a grip tab 10, a corresponding engagement opening can also be provided in the area of the side element 7, into which the finger can easily be inserted in order to pivot open the side element 7, such an engagement opening possibly also in addition to the rounded corners 22 can be provided.

the Figures 12-14 show a folding box 1 according to the invention in a second embodiment, the same reference numerals being used as far as possible for the same parts.

This folding box 1 also consists of a cover 2 and an inner body 3 which is cuboid in the unfolded form, with Fig. 12 the folding box in the unfolded state and Fig. 13 shows the folding box in a partially unfolded state with the inner body 3 unfolded.

The cover 2 here also consists of four folding elements arranged in a row and pivotably connected, namely a bottom element 4, a first side element 5, a cover element 6 and a second side element 7, on which a tuck-in flap 9 and a grip tab are also located on the free longitudinal edge 8 10 (see Fig. 14 ) is provided. Here, too, the cover consists of a sufficiently rigid cardboard or cardboard and is preferably provided with a decorative paper 11 on the inside and a decorative paper 12 on the outside, with a decorative film instead of a decorative paper can be used. In this respect, the cover 2 corresponds to the cover 2 as in the first embodiment according to FIG Figures 1 - 11 described.

The inner body 3 here also comprises four side walls, namely the respective opposite side walls 14, on which two stiffening walls 15 are pivotably articulated. Furthermore, two further opposing side walls 16 are provided so that the inner body is closed to form a cuboid shape, see Fig. 13 . The side walls 14 and 16 are glued to one another via corresponding kink corners 17, similar to the folding box from the Figures 1 - 11 . A floor 13 is also provided.

Unlike the embodiment according to FIG Figures 1 - 11 Here the inner body 3 is formed from five separate parts which are fastened separately to the base element 4 of the cover 2. Thus, the two side walls 14 with their articulated stiffening walls 15 are two separate parts, as are the two side walls 16 with the kink corners 17 formed on them, as well as the base 13. To fix the side walls 14, 16, the side walls each have adhesive flaps 26 which in Fig. 13 are indicated by dashed lines, and via which they are glued to the floor element 4 via an adhesive layer. The base 13 is also glued to the base element 4 and covers the adhesive tabs 26, so these are not visible in the finished state. The side walls 14, 16 and the stiffening walls 15 are made of sufficiently rigid cardboard or cardboard. The bottom 13 can also be made of a correspondingly stiff cardboard or cardboard, but it can also be just a stiffer paper. In the present case, its task is ultimately to conceal the adhesive tabs 26.

For unfolding, the inner body 3 is first unfolded here too, in that the side walls 14, 16 are erected, which is easily possible since these are coupled in terms of movement via the kinked corners 17. The two stiffening walls 15 are then folded inwards into contact with the inner sides of the side walls 14; they can there, as in the embodiment according to FIG Figures 1 - 11 , again in their position via corresponding locking connections be fixed, albeit in Fig. 12 not shown in detail. The cover 2 is then folded over and the tuck-in flap 9 is inserted into the tuck-in slot 20.

This insertion slot 20 is formed in this embodiment in a different way than in the embodiment according to FIG Figures 1 - 11 . In this variant of the invention, a cut-out 27 is provided on the base element 4, the base element 4 being covered on the outside by the decorative paper 12, which also overlaps the cut-out 27. The side wall 14 adjoins the opposite side, or its adhesive flap 26, which runs over the recess 27. The glue flap 26 is in Fig. 14 indicated, although it is not visible as such in this view. Here, the insertion slot 20 is not formed between the base 13 and the base element 4, as in the embodiment according to FIG Figures 1 - 11 , but via a cut-out 27 covered on both sides, which is open at the lower edge of the box, so that the tuck-in flap 9 can be pushed in. If the folding process is continued according to Fig. 14 So the second side element 7 would now be pivoted onto the side wall 14 and applied, with the insertion tab 9 being pushed into the insertion slot 20.

Corresponding additional elements, as in the case of the folding box 1 according to FIG Figures 1 - 11 are provided, can also with the folding box 1 according to Figures 12-14 be provided. It is thus conceivable to attach corresponding tabs to the reinforcement walls 15, which make it possible to pull them out of their folded-in position again after they have been folded in. Alternatively, there can also be punched-out edges on the edge, which can be gripped from behind with the finger. Instead of the decorative papers, decorative foils can also be used. Furthermore, of course, the design of the insertion slot 20 can also be as in the embodiment according to FIG Figures 1 - 11 respectively.
