Description

  • The invention relates to an all-round closed, openable and reclosable folding box in the form of a three-sided straight prism, which consists of an erected, one-piece blank made of a flat material and has three square longitudinal walls and two triangular side walls, one of the three longitudinal walls being hinged on one of the longitudinal edges. The invention further relates to corresponding blanks from which folding boxes of this type can be produced by erecting and, if necessary, gluing.
  • Folding boxes in the basic form of a three-sided straight prism and corresponding blanks are already known.
  • For example, US-A-42 53 601 relates to such a folding box, which has four longitudinally interconnected longitudinal walls, two of which are folded over one another, and a special arrangement of double triangular side walls with which the folding box holds together in a self-locking manner. This folding box can be sent to the triangular side surfaces are opened and have a perforation for this purpose.
  • In this known folding box, a perforation can also be provided along a longitudinal edge of the side walls, which can be torn open to open it; however, this opening leads to the destruction of the folding box, which accordingly cannot be closed again.
  • From DE-A-37 02 673 a triangular pack of similar construction with beads on the triangular side faces is known, which is open on one long side and has two double longitudinal walls. Since this previously known folding box is not closed on all sides, but is open on one long side, the inside of the box is always accessible, so that an additional cover is required in order to keep objects packed therein in the box.
  • From DE-A-29 01 616 a folding box with a polygonal cross section, which can also be triangular, can be opened on one side and consists of an inner housing and an outer housing pushed over the inner housing and telescopically displaceable thereon, as well as cover parts which are designed in this way that the folded cover parts can be opened or closed by moving the outer housing relative to the inner housing.
  • A folding box in the form of a three-sided prism is also known, which is used as packaging for triangular chocolate bars. This folding box has three square longitudinal walls and two triangular side walls, the third longitudinal wall in the sequence having an adhesive flap which is glued to the first longitudinal wall, so that the prism shape is independent is predetermined by the side walls, which in turn are arranged on the second longitudinal wall in the sequence and are glued to the first longitudinal wall with an adhesive flap. Triangles provided on the third longitudinal wall, which lie below the side surfaces, stabilize the prism structure. This box is opened at one end by folding down a prism part with a side wall after tearing off a perforated tear-off strip running over two of the three longitudinal walls. It is therefore not possible to reclose this box.
  • The invention has for its object a folding box in the form of a three-sided straight prism, which is easy to open and close on one long side, has high dimensional stability and can be produced by simply opening a one-piece blank, preferably without gluing, as well as to indicate corresponding cuts.
  • The task is solved according to the requirements.
  • The dependent claims relate to advantageous embodiments of the inventive concept.
  • The folding box according to the invention has the shape of a three-sided straight prism, is closed on all sides and is easy to open by folding down a longitudinal wall and to be closed again by folding back the longitudinal wall. Correspondingly, it has three square longitudinal walls and two triangular side walls, the side walls each being connected to a longitudinal wall at one of the side edges and being fixed to one of the other two longitudinal walls with an insertion tab provided on the side walls; it is characterized in that one of the Longitudinal walls can be folded down around one of the long edges and can be fixed in the unfolded state with a locking tab provided on their free long edge, which can be inserted into a corresponding slot provided in the long wall which is adjacent to the free long edge or in a long edge of this long wall .
  • The folding box concept according to the invention can be realized in particular in two basic types: in the first folding box type, a bottom wall of the same size and shape is provided under the hinged side wall, which is glued to the adjacent longitudinal wall by means of an adhesive flap, so that even when the side wall is folded down and before the first opening Box closed on all sides is present, which can be opened by pressing in a wall part of the lower wall predetermined by perforation and closed again by folding back the folded side wall and inserting the closing flap. As a result of the edge region of the lower wall remaining after the perforated wall part has been pressed in, the folding box remains stabilized even after the first opening by pressing in the perforation, in addition to the stabilization by the side walls.
  • In the second basic type of the box according to the invention, the box on the relevant long side is opened completely by folding down a longitudinal wall and can be closed again by folding back this side wall and inserting the closure flap. This type of folding box has the advantage that the maximum possible opening is achieved, which facilitates both the filling of the box and the removal of objects from it. In simple variants of this type of box, the prism structure can be glued to the side walls with a longitudinal wall Insert or adhesive tabs and, in the case of particularly preferred variants, be stabilized without gluing solely on account of the folding and with the aid of insert tabs.

  • In the drawings explained below, identical or comparable parts of the folding boxes or blanks according to the invention are designated by the same reference numbers. Those reference numbers which denote the walls of the folding boxes are identified below and in the drawings by underlining.
  • The folding box of the first basic type according to the invention shown in FIG. 1 has the blank shown in FIG. 2. The prismatic base body of this folding box comprises, as can be seen from FIGS. 1 and 2, three longitudinal walls 1 , 2 and 3 , the longitudinal wall 1 being shown folded down in FIG. 1, and the triangular side walls 4 and 5 . A lower wall 17 is provided under the foldable longitudinal wall 1 .
  • As can be seen from the cut of FIG. 2, the longitudinal wall 1 , the longitudinal wall 2 , the longitudinal wall 3 and the lower wall 17 are arranged correspondingly one behind the other; between the said walls there are folding lines 38, 39 and 43; on a fold line 44 provided at the end of the lower wall 17 there is an adhesive flap 23 which is glued in alignment with the longitudinal wall 2 on the longitudinal edge 11 (FIG. 1). On the side edges 6 (FIG. 1) of the bottom wall 17 , the triangular side walls 4 and 5 are formed on fold lines 40, on the side edge of which lies towards the adhesive flap 23, insert tabs 10 are provided on fold lines 41. For better illustration, the side wall 5 with the insertion tab 10 is shown in a somewhat pulled-out state in FIG. 1. The insertion tabs 10 can be glued to the longitudinal wall 2 .
  • On the two side edges of the longitudinal wall 3 42 folding tabs 45, 46 are formed on the folding lines, with which one higher stability and better side sealing of the folding box can be achieved. The insertion tabs 45, 46 can be glued to the side walls 4 and 5 if necessary.
  • The lower wall 17 has a perforation 18 which runs in a U-shape approximately parallel to the side edges and the fold line 43, which separates the longitudinal wall 3 from the lower wall 17 . By means of this perforation 18 and a fold line 20 connecting the ends of the U-shaped perforation 18, a wall part 19 that can be pressed in is predetermined, which allows the closed folding box to be opened for the first time after the longitudinal wall 1 has been folded down. To make it easier to press in the wall part 19 , additional fold lines 21 can be provided, which advantageously each start from one end of the fold line 20 and end in the middle of the part of the perforation 18 parallel to the longitudinal edge 12 or the fold line 43.
  • In the embodiment shown, the longitudinal wall 1 can be folded around the longitudinal edge 11 (FIG. 1) of the folding box, which is predetermined by the corresponding folding line 38 of the blank.
  • On the free longitudinal edge 14 of the foldable longitudinal wall 1 , a closure flap 15 is provided in the center, which can be inserted into a slot 16, which in the present exemplary embodiment is provided in the longitudinal edge 12 of the folding box, ie on or in the fold line 43 of the blank. Depending on the length of the locking tab 15, the slot 16 can also be arranged in the region of the longitudinal wall 3 .
  • FIG. 3 shows a schematic sectional illustration of the folding box from FIG. 1 with the longitudinal wall 1 folded down, on which the closure flap 15 is provided. By folding down the longitudinal wall 1 , the lower wall 17 is accessible and can be opened accordingly by pressing in the perforation (cf. FIG. 2). Fig. 3 also shows that the bottom wall 17 is glued to the longitudinal wall 2 via the adhesive tab 23, which preferably represents the bottom surface. The prism structure from the lower wall 17 of the longitudinal wall 2 and the longitudinal wall 3 with the longitudinal edges 11, 12 and 13 is already stabilized by the gluing, so that in this embodiment of the folding box according to the invention a gluing of the insertion flaps 10 provided on the side walls 4 , 5 with the longitudinal wall 2 is not absolutely necessary.
  • Fig. 4 shows the same folding box in a schematic sectional view with closed longitudinal wall 1 , the closure tab 15 is inserted into a slot which is arranged in the longitudinal edge 12. In this state, the lower wall 17 is covered by the longitudinal wall 1 . The longitudinal wall 1 can be folded around the longitudinal edge 11. In the closed state, the prism structure formed from the longitudinal walls 1 , 2 , and 3 is further stabilized.
  • According to an advantageous embodiment of the above-described folding box of the first basic type, as shown in FIGS. 1 and 2, a continuous folding line 22 is provided in the longitudinal wall 3 exactly in the middle and parallel to the longitudinal edges 12 and 13, which is also provided by the Insert tabs 45, 46 passes and along which the longitudinal wall 3 with the insert tabs 45, 46 can be bent such that their halves come to lie one above the other.
  • This ability to bend has two advantages: on the one hand, after the blank has been folded along the folding line 22 and the adhesive flap 23 has been folded inwards at the folding line 44, the adhesive flap 23 can be glued to the longitudinal wall 2 . This pre-gluing results in a flat structure that can be stored, transported and handled easily and in a space-saving manner in this state and allows easy erection, the resulting prism structure, despite the previous kinking of the longitudinal wall 3 , through the side walls 4 , 5 and Insert tabs 45, 46 is stabilized. On the other hand, the erected folding box can be flattened out again by pushing the longitudinal edges 12, 13 or pushing the longitudinal wall 3 outwards from the inside of the box after pulling out the side walls 4 , 5 and the insertion flaps 45, 46. This state, which corresponds to the pre-glued state of the blank before erection, is shown in FIGS. 5, 6 and 7 when the longitudinal wall 1 is folded down. The folding box glued over the adhesive flap 23 is flattened to a certain extent, the lower wall 17 coming to lie over the longitudinal wall 2 (FIGS. 5 and 6) and the two halves of the longitudinal wall 3 lying one on top of the other. The fold line 22 correspondingly forms the outer edge of the resulting flat structure, whose fold lines 39 and 43, which specify the longitudinal edges 13 and 12, lie in the plane of the flat structure, while the fold lines 38 and 44 correspond to the longitudinal edge 11 (FIG. 1 , 3, 4). The longitudinal wall 1 with the closure flap 15, which is provided on the longitudinal edge 14 of the longitudinal wall 1 , is folded down on the folded edge 38.
  • The representation of FIG. 6 shows a top view of the pre-glued blank of FIG. 2, wherein, as also indicated in FIG. 5, the lower wall 17 is at the top and the Longitudinal wall 2 covered accordingly. One can also see the side walls 4 and 5 provided on the bottom wall 17 on the fold lines 40 with the insertion tabs 10 located on the fold lines 41, and the longitudinal wall 1 underneath, with the closure tab 15 provided on the longitudinal edge 14. The longitudinal wall 3 is accordingly only half closed see since their two halves are on top of each other. Since the fold line 22 also passes through the insertion flaps 45, 46, these insertion flaps can also only be seen with their part lying on top, which in the case shown covers the part underneath, as indicated by dashed lines. In the lower wall 17 , the wall part 19 that can be pressed in is shown, which is predetermined by the perforation 18 and the corresponding fold lines 20 and 21, as explained above with reference to FIGS. 1 and 2. The - not visible - adhesive flap 23, which is provided on the fold line 44, lies on the longitudinal wall 2. On the fold line 43, the slot 16 for the closure flap 15 of the longitudinal wall 1 is indicated, which comes to lie at the top in this illustration.
  • FIG. 7 corresponds to the glued flat blank from FIG. 2, the longitudinal wall 2 , which advantageously represents the bottom surface, now lying at the top, in contrast to the representation from FIG. 6. The remaining details of this glued blank correspond to those of Fig. 6 with the difference that now the other half of the longitudinal wall 3 is on top and is visible, so that the two halves of the insertion tabs 45, 46 are visible in the contour, since they are not congruent are. Since the longitudinal wall 1 is attached to the fold line 38 on the longitudinal wall 2 , the fold line 38 which separates the longitudinal walls 1 and 2 from one another is consequently visible in this illustration. Furthermore, the fold line 39 is also visible, which lies between the longitudinal walls 2 and 3 .
  • 8 and 9 a folding box according to the invention of the second basic type is shown, with FIG. 8 showing a perspective view and FIG. 9 showing the corresponding cut of this folding box, in which the structure is basically the same as that of the folding box from FIG. 1 with the The difference is that no bottom wall is provided, so that a side wall of the prism can be fully opened by folding down the longitudinal wall 1 . In order to stabilize the prismatic structure in this case, the side walls 4 , 5 are provided on the longitudinal wall 3 on the side edges 6. The triangular side walls 4 , 5 , which are attached to the side edges 6 of the longitudinal wall 3 , have on the side edge 9, which corresponds to the fold line 41 of FIG. 9, which lies towards the longitudinal wall 2 , an insertion tab 10, which after erection the folding box is glued to the longitudinal wall 2 to stabilize the prism shape. The longitudinal walls 1 and 2 are separated from one another by a fold line 38, the longitudinal walls 2 and 3 by a fold line 39. The slot 16 for the closure flap 15, which is provided on the free longitudinal edge 14 of the longitudinal wall 1 , is provided within the longitudinal wall 3 ; Accordingly, the closure flap 15 is somewhat longer than the folding box of FIGS. 1 to 7 and has an additional fold line 37, the distance from the free longitudinal edge 14 corresponds approximately to the distance of the slot 16 from the fold line 39.
  • 10, 11 and 12 show a further, particularly advantageous embodiment of the folding box of the second basic type according to the invention with a foldable longitudinal wall which has a peripheral edge. Fig. 10 is a perspective view, while Fig. 11 shows the corresponding blank and Fig. 12 shows a schematic side view of this folding box.
  • The folding box shown in FIG. 10 has a longitudinal wall 1 , on the free edges 14, 24, 25 of which a continuous edge runs, which consists of two lateral edge parts 26, 27 and a central edge part 28. The planes of the lateral edge parts 26, 27 are perpendicular to the plane of the longitudinal wall 1 , while the plane of the central edge part 28 is oriented at an angle α to the plane of the longitudinal wall 1, which is approximately the same size or slightly smaller than the angle β forms the plane of the longitudinal wall 3 with the longitudinal wall 1 closed, with its plane, as can be seen from FIG. 12.
  • 11 in turn includes the three longitudinal walls 1 , 2 and 3 , which are separated from one another by fold lines 38 and 39, respectively. The triangular side walls 4 , 5 are provided on the central longitudinal wall 2 on fold lines 40 and carry insert tabs 10 provided on a fold line 41 on their edge lying towards the longitudinal wall 3 .
  • On the first longitudinal wall 1 in the order, the lateral edge parts 26, 27, which have a trapezoidal shape, are arranged on fold lines 49. Since the edges of the trapezoidal edge parts 26 and 27 lying towards the side walls 4 , 5 come to lie on the folding lines 40 when the folding box is erected, the trapezoidal angle α 1 corresponds to the angle β 1 that the free edge of the side walls 4 and 5 has with the folding line 40 forms. In the case of the folding box preferred according to the invention, the angle β is 60 ° in the form of a three-sided prism with the side walls 4 , 5 in the form of equilateral triangles. In this preferred case, the angles α₁, β₁ and β are each equal to 60 °. The other trapezoidal angle α corresponds approximately to the angle β when the box is erect; this angle α is also in preferred case equal to 60 °. Depending on the thickness of the flat material used for the folding box and the real dimensioning of the blank, the angles .alpha.1 and .alpha. Can also be somewhat smaller than the angles .beta.1 and .beta., Respectively, in order to enable the box to be erected correctly. On the trapezoidal edge parts 26, 27, adhesive flaps 47, 48 are provided on the edges pointing away from the cut on fold lines 50, which may have adhesive flaps 52 formed on fold lines 51. When the folding box is erected, the adhesive tabs 47, 48 are either glued one above the other and / or are attached to the longitudinal edge 14 of the longitudinal wall 1 with the adhesive tabs 52. Instead of the two adhesive tabs 47, 48, a single adhesive tab can also be provided on one of the trapezoidal edge parts 26, 27, the length of which advantageously corresponds to the length of the longitudinal wall 1 . The two adhesive tabs 51 thus form the central edge part 28, while the trapezoidal edge parts 26, 27 form the lateral edge.
  • 11 also shows that the closure flap 15 provided on the free longitudinal edge 14 of the longitudinal wall 1 has an end part 34 which can be folded over along a centrally interrupted folding edge 35 and which in the region of the interruption of the folding edge 35 has a punched-out nose 36 which projects towards the folding box wearing. To lock the closed position of the foldable longitudinal wall 1 , the closure flap 15 can be folded over the longitudinal edge 12 (cf. FIG. 12) onto the side wall 3 , whereupon the nose 36 can then be inserted into the slot 16 which is in the longitudinal wall 3 is provided, as can also be seen in FIGS. 10 and 11. In order to make it easier to fold the closure flap 15 over the longitudinal edge 12, a fold line 62 (FIGS. 10, 11) coming to lie over the longitudinal edge 12 is advantageously provided. By pressing the End part 34 to the flat contact on the longitudinal wall 3 , the end part 34 of the locking tab 15 is locked. The distance of the slot 16 from the longitudinal edge of the longitudinal wall 3 lying at the end of the cut substantially corresponds to the distance of the folded edge 35 of the closure flap 15 from the longitudinal edge 14 of the longitudinal wall 1 ; the width of the slot 16 is adapted to the width of the nose 36 of the end part 34 of the locking tab 15.
  • In this embodiment of the folding box according to the invention, the insertion tabs 10 are provided or designed as adhesive tabs and glued to the longitudinal wall 3 in order to stabilize the prism structure. The two insertion tabs 10, which are provided on the side walls 4 , 5 , have corresponding recesses 58 in the area that comes to lie under the slot 16, so that the slot 16 is not covered by the insertion tabs 10. The adhesive bonding of the two adhesive tabs 10 can also be such that there is no bonding under the longitudinal wall 3 in the region of the slot 16, so that the nose 36 of the sealing tab 15 can then be inserted between the longitudinal wall 3 and one of the adhesive tabs 15, which means that one more more secure determination is achieved. In this case, the recesses 58 are not provided accordingly.
  • 12 shows a schematic side view of this folding box in the open state with the longitudinal wall 1 folded down. The side view shows the side edge part 27, which is provided on the free side edge 24 of the longitudinal wall 1 , and the middle edge part 28, which is formed by the two adhesive tabs 47, 48. The folded-down longitudinal wall 1 carries the closure flap 15. The fold line 38 between the longitudinal walls 1 and 2 forms the longitudinal edge 11, while the prism structure from the longitudinal wall 2 , the longitudinal wall 3 and the side wall 5 defines the longitudinal edges 12 and 13. Fig. 12 also shows that the angles α and ß or α ₁ and β₁ must correspond at least approximately in order to enable the folding box to be erected or closed.
  • 13 to 17 a particularly preferred embodiment of the folding box according to the invention is shown, which is basically constructed in the same way as the folding box of FIGS. 10 to 12, but with the difference that between the lateral edge parts 26, 27 of the longitudinal wall 1 and the Side walls 4 and 5 triangular gussets 29 (FIGS. 14, 15) with a central gusset fold 30 are provided, as a result of which the peripheral edge of the foldable longitudinal wall 1 consisting of the lateral edge parts 26, 27 and the central edge part 28 extends as far as the side walls 4 , 5 continues and is integrated with them. Due to the circumferential edge integrated with the side walls 4 , 5 , the contents of the folding box can be poured out onto the folded-down longitudinal wall 1 after the longitudinal wall 1 has been folded down, and even small parts are reliably retained on the longitudinal wall 1 due to the completely continuous edge.
  • However, a further, particularly advantageous effect is achieved by the two gussets 29: when the longitudinal wall 1 is completely folded down, as shown in FIG. 15, the gussets 29 are flat, that is to say they have no kink around the gusset fold 30 and lie in the gusset same plane as the lateral edge parts 26 and 27. When the longitudinal wall 1 is folded up, the gussets 29 are subject to a corresponding compression, which leads to the gussets 29 being bent around the gusset fold 30, whereby it is basically irrelevant whether the gusset fold 30 is bent towards the inside of the box or outwards. By embossing the fold lines during box production, a preferred direction for the buckling can be specified. Regardless of whether the gusset folds 30 are bent outwards or inwards, i.e. the gussets initially protrude outwards or inwards, when the longitudinal wall 1 is folded up, a state is reached in which one of the triangular gusset halves 29a, 29b contacts the gusset 29 an adjacent wall is approximately flat and approximately parallel to the system. 13 shows both possibilities. If the gusset 29 projects outwards when the longitudinal wall 1 is folded up with the kinked gusset fold 30 (FIG. 13, bottom left), a state is accordingly reached in which the gusset half 29a comes to bear against the lateral edge part 27 from the outside; when the gusset 29 folds inwards (FIG. 13, top right), the gusset half 29b lying towards the associated side wall 4 comes to rest against it. This state is reached when, in the preferred prism shape with side walls 4 , 5 made of equilateral triangles, the longitudinal wall 1 is folded up by an angle γ (see FIG. 13) of approximately 60 °, that is also an angle of 60 ° between the The upper edge of the edge parts 26, 27 and the adjacent side edge 6 of the relevant side wall is present. 13 shows this intermediate state when the longitudinal wall 1 is folded up. When the longitudinal wall 1 is folded up further beyond the position described, that is to say by increasing the angle γ (see FIG. 13), there is a more or less abrupt inhibition, since a considerably higher force is required suddenly to further close the folding box, because for further folding up the longitudinal wall 1, the gusset half not lying against a wall between the lateral ones Edge parts 26, 27 and the associated side wall 4 and 5 is transversely and spreads these two parts apart. 13, the gusset half 29b correspondingly spreads the side edge part 27 inwards and the side wall 5 outwards for the gusset located at the bottom left, while in the gusset located on the top right, the gusset half 29a spreads the side edge part 26 and the associated side wall 4 apart . Due to this spreading apart adjacent edge parts and side walls when the longitudinal wall 1 is folded up, a type of spring action is achieved which only stops when the longitudinal wall 1 is practically completely folded up, so that a more or less pronounced locking effect results depending on the material.
  • Analogous effects are achieved in reverse when this folding box is opened: the longitudinal wall 1 is first folded down against the spring action due to the spreading of one half of the gusset until a corresponding opening angle of the folding box is reached, which is approximately 60 ° in the preferred embodiment explained above. From then on, the further folding down of the longitudinal wall 1 can be carried out with less effort.
  • Otherwise, the two gussets 29 lie completely in the same direction, for example both outwards, when the folding box is completely closed by folding up the longitudinal wall 1 when it is reopened, particularly when this is predetermined by appropriate embossing of the gusset folds 30 and the adjacent fold lines. However, the direction of folding of the gusset 29 does not affect the spring effect achieved. This spring and locking effect caused by the gusset represents a particular advantage of this embodiment of the folding box according to the invention, since in this way both the closed state and the state of the partial folding down of the longitudinal wall 1 are preferably fixed to a certain extent by latching by approximately 60 °. In particular, the reclosing and keeping the folding box closed is facilitated because this embodiment of the folding box already remains in a somewhat resilient manner in the closed state even without being fixed by the closing flap 15.
  • FIG. 14 shows a blank of a folding box according to the invention which corresponds to the folding box from FIG. 13. This blank comprises the square longitudinal walls 1 , 2 and 3 with fold lines 38, 39 lying between them, the side walls 4 and 5 with the insertion tabs 10 arranged on the fold lines 41, the trapezoidal lateral edge parts 26, 27 provided on fold lines 49 with the fold lines 50 arranged insertion tabs 55, 56 and the slot 16 for the closure tab 15, which is constructed in the same way as the closure tab of the blank of FIG. 13. The insertion tabs 10 can also have recesses 58 in the area below the slot 16 comes to rest. With regard to the elements of the blank mentioned, there is consequently agreement with the blank of FIG. 13, so that what has been said about this also applies to the blank of FIG. 14.
  • In contrast to the blank of FIG. 11, the gussets 29 with the gusset fold 30 are provided between the lateral edge parts 26, 27 and the associated side walls 4 , 5 . For the angles .alpha. And .beta. Which correspond to one another, what has already been said above with regard to FIGS. 10 to 12 also applies accordingly.
  • Another difference from the folding box according to FIGS. 10 to 12 is that, according to an advantageous embodiment, the middle edge part 28 and the longitudinal wall 3 are doubled:
  • At the outer end of the longitudinal wall 1 , the middle edge part 28 is arranged on a fold line 53, which continues, via a fold line 54, into a double edge part 32, on which only the closure flap 15 is provided, which in turn provides the end part 34 that can be bent off via a fold edge 35 has, in which the nose 36 is punched out. A slot 33 is provided in the fold line 53, which corresponds to the width of the closure flap 15. When this folding box is erected, the closure flap 15 is inserted through the slot 33 after the corresponding insertion of the insertion flaps 55, 56, the double edge part 32 being bent around the fold line 54 and engaging from the inside against the middle edge part 28 with insertion flaps 55, 56 therebetween . The insertion tabs 55, 56 have a corresponding small recess in the area of the slot 33, so that the slot 33 is not covered in the erected state. When the edge parts of the longitudinal wall 1 are erected, the closure tab 15 protrudes completely from the slot 33 as if it were attached to the free longitudinal edge 14 of the longitudinal wall 1 . The closure flap 15 advantageously has a fold line 62 along this edge in order to make it easier to bend. This duplication of the central edge part 28, which is considerably facilitated by pulling through the closure flap when erecting, considerably stiffens the foldable longitudinal wall 1 , in particular in the edge region, which is very advantageous both in the open and in the closed state of the folding box is.
  • The schematic side view of FIG. 15 shows how the double edge part 32, with the closure flap 15 provided at its end, bears against the middle edge part 28 in the erected state, the closure flap 15 projecting outwards on the longitudinal edge 14. FIG. 15 also shows the position of the gusset 29 with the gusset halves 29a, 29b, which lies between the lateral edge part 26 and the associated side wall 5 .
  • Fig. 16 shows an enlarged perspective view of the duplication of the central edge part 28 by the double edge part 32 with the locking tab 15 inserted through the slot 33 with the above-described construction of the end part 34 and nose 36, which has a kink edge 35 on which the nose 36 is punched out and has a fold line 62 which facilitates guiding the closure flap 15 around the longitudinal edge 12.
  • 14 also shows a further advantageous variant of this folding box, in which the longitudinal wall 3 is also doubled. Correspondingly, it has a double wall 31 at its end on a fold line 57, which, as can be seen in FIG. 15, is folded around the fold line 57 when it is erected into the interior of the box and then bears against the longitudinal wall 3 from the inside. In order to facilitate this inversion, a fold line 59 can advantageously be provided in the end region of the double wall 31, which is indicated by dashed lines in the blank in FIG. 14. By doubling the longitudinal wall 3 , a considerable reinforcement of the prismatic box structure is achieved, which is thereby particularly dimensionally stable, in particular if the central edge part 28 is also doubled. On one of the side edges 60 of the longitudinal wall 3 , a hanging flap 61 arranged on a corresponding fold line can also be provided, which advantageously has the shape of a segment of a circle; the adjacent insert tab 10 has a corresponding recess in the blank. The hanger can have a hole, so that the folding box can be hung on appropriate pins, etc.
  • The closing of this folding box with the specially designed closing flap 15 takes place in the same way as described above with reference to the folding box of FIGS. 10 to 12. 17 illustrates this process in detail. After the longitudinal wall 1 has been completely folded up, the locking tab protruding from the slot 33 is bent toward the longitudinal wall 3 and the nose 36 is inserted into the slot 16, the end part 34, which can be bent at the folding edge 35, being used as a lever, as it were, which is indicated by the arrow in FIG. 17 in order to fix the nose 36 in the slot 33. This embodiment of the closure flap is particularly advantageous in the case of a double longitudinal wall 3 , since in this case the nose 36 is inserted into the flat space between the longitudinal wall 3 and the double wall 31, that is to say it lies practically parallel to these walls. This results in a particularly good fixation of the closure flap, which on the other hand is also easy to release.
  • The folding box of FIGS. 11 to 17 leads to very special advantages. The one-piece cut is, just as with the other folding boxes described above, easy to erect and without erecting machines. The resulting folding box does not have to be glued, but instead is stabilized by simply inserting the insertion tabs 10, 55 and 56. The folding box also has a particularly high stability, in particular when the middle edge part 28 and the longitudinal wall 3 are doubled, so that even sensitive goods can be stored and transported in these boxes. Due to the integrated, continuous edge, the longitudinal wall 1 can take over the function of a kind of chute when folded down, which is very cheap, especially for small parts. Because of the gusset with gusset fold, an extraordinarily advantageous spring and latching effect is achieved, which facilitates the opening and reclosing of this folding box and in particular also contributes to securing the closed state. By doubling the longitudinal wall 3 , the closure tab 15 is also particularly securely fixed with the nose 36.
  • Because of their prismatic shape, the folding boxes according to the invention also do not roll away on inclined documents and are easy to stack, since only minimal empty spaces are created when stacked. Furthermore, numerous shape variants are possible, since both the dimensions and angles of the side walls and the dimensions of the longitudinal walls can be varied.
  • Due to their design, the folding boxes according to the invention can also be easily dismantled into flat blanks, which facilitates storage and recycling as waste paper.
  • The folding boxes or blanks according to the invention can in principle be produced from any flat materials, cardboard, paper, cardboard or similar materials based on cellulose being very cheap.
  • The flat material can generally consist of a single material or of mixtures or can be a laminate or composite material.
  • The flat material of the folding boxes according to the invention can also consist of a plastic or a material coated with plastic. Such coatings are particularly suitable for the cellulose-based materials, which thereby obtain a protective coating, on the basis of which the folding boxes can also be suitable, for example, for the packaging of foods. The folding boxes can alternatively also consist of metal sheets or metal foils or of flat materials coated with sheets or foils.
  • Folding boxes according to the invention, in particular geometrically similar boxes, can also be stored and stored one inside the other, in particular if the box type of FIGS. 10 to 17 is involved.
  • Another particularly advantageous embodiment of the folding boxes or blanks according to the invention consists predominantly or exclusively of a biological or biodegradable material, advantageously based on starch, casein and / or chitin.
