Description

[0001] The invention relates to a folding box made of paper or cardboard with a closure that cannot be easily opened, in particular a closure that cannot be opened by children, and a reclosure.

[0002] US 2017 / 0036808 A1 describes a package with a locking tab and a locking slot, wherein the at least one locking slot engages with the at least one locking tab when the child-resistant package is in a locked position.

[0003] US 2020 / 0180808 A1 describes a child-resistant package comprising a tray insert and an outer sleeve, each having a locking notch and a locking tab that can be locked or unlocked.

[0004] DE 102007053977 A1 describes a packaging made of a flat material, with a box-like packaging body, and at least one slipcase partially enveloping the packaging body when the packaging is closed, wherein the packaging body can be pulled out of the slipcase at an open side of the slipcase.

[0005] Various types of such packaging are known, which are usually made of plastic.

[0006] However, plastic is problematic in terms of its disposal and recycling. One need only point to the plastic waste in the world's oceans.

[0007] Efforts have already been made in the past to propose appropriate cardboard packaging. While these work as intended, some are difficult to open even for adults or lack the child-resistant features required, for example, for packaging detergents or similar products.

[0008] The object of the invention is to create a cardboard packaging that is also suitable for packaging goods that should not be accessible to children. Furthermore, the object of the invention is to ensure that the packaging is resealable while maintaining the same level of security.

[0009] This object is achieved by a folding box according to claim 1.

[0010] This ensures that a locking mechanism is in place and that it can also be released easily.

[0011] According to the invention, it is also very advantageous if a bottom wall flap is provided which is folded onto the bottom wall in the sleeve and can take up the entire length of the sleeve.

[0012] This stabilizes the sleeve and gives it increased rigidity.

[0013] According to a further development of the invention, it is very advantageous if at least one side wall flap is hinged to the free end of the sleeve and folded into the sleeve and can take up the entire length of the sleeve.

[0014] This also stabilizes the sleeve and gives it increased rigidity.

[0015] It has proven to be very advantageous if at least one side wall tab has a recess which occupies at least part of the length of the sleeve.

[0016] This allows the extension of the insert to be limited by a corresponding tab of the insert engaging in the recess.

[0017] Furthermore, it has proven to be very advantageous if the back wall has a handle hole.

[0018] This hole allows access to the locking tab. The hole can be designed as an elongated hole.

[0019] Furthermore, it has proven to be very advantageous if the rear wall, a side wall, the bottom wall and / or the top wall has an additional handle hole.

[0020] A second lock can be operated through this additional handle hole.

[0021] According to a further embodiment of the invention, it is also extremely advantageous if an additional locking tab is provided in the sleeve.

[0022] This additional locking tab forms an additional lock that must be operated separately to open the packaging.

[0023] According to a further development of the invention, it is extremely advantageous if the insert has a bottom wall, two longitudinal side walls hinged thereto and two narrow side walls hinged to the bottom wall, wherein one narrow side wall serves as the rear wall and the other narrow side wall serves as the front wall.

[0024] This creates a stable, bowl-shaped insert that can hold contents.

[0025] It has proven to be very advantageous if a rear wall flap is hinged to the rear wall and folded onto the rear wall.

[0026] This creates a stable back wall.

[0027] It is also extremely advantageous according to the invention if a recess is arranged in the rear wall at the end facing away from the base wall, which recess can extend into the rear wall flap or if a recess corresponding to the recess in the rear wall is arranged there.

[0028] The locking tab of the slipcase can engage in this recess and thus interact with the insert and lock it in the slipcase.

[0029] It is extremely advantageous according to the invention if at least one locking tab is provided on the edges of the longitudinal side walls directed towards the rear wall and / or on the lateral edges of the rear wall.

[0030] This locking tab is bent so that it rests on the side wall of the insert and engages in the recess of the side wall tabs of the slipcase, thus limiting the removal of the insert from the slipcase.

[0031] A further very advantageous embodiment of the invention is provided if a locking tab is provided on at least one longitudinal side wall, on the bottom wall and / or on the rear wall, which can be arranged corresponding to the additional handle hole of the slipcase.

[0032] This means the packaging can only be opened by simultaneously pressing two locking devices. By arranging the packaging accordingly, two-handed operation can be enforced. This is generally impossible for small children, resulting in child-resistant packaging.

[0033] According to a further development of the invention, it is also extremely advantageous if an additional locking device is provided.

[0034] This additional locking mechanism ensures secure locking not only upon initial opening, but also upon resealing. Even then, it ensures that the packaging cannot be opened by unauthorized children. Opening the packaging requires several steps simultaneously. Depending on the design, this may require two-handed operation.

[0035] According to a further development of the invention, it is extremely advantageous if adhesive tabs are provided on the side edges of the rear wall, the longitudinal side walls and / or the front wall, which can be designed to be closed.

[0036] With the help of these adhesive tabs, the individual walls of the insert are connected to each other in a liquid-tight manner.

[0037] A further very advantageous embodiment of the invention is provided when a reinforcing flap is hinged to the front wall.

[0038] This reinforcing flap makes the front wall so rigid that it cannot be bent and the contents can be removed without unlocking the locking flap.

[0039] Furthermore, it has proven to be very advantageous if the material of the insert is provided or coated in a liquid-tight, liquid-repellent, grease-tight, grease-repellent or the like manner, in particular if the insert is provided on its inside with a resistance layer, in particular against liquids, wherein the resistance layer can be designed as a lacquer application, coating, impregnation or lamination.

[0040] This also makes it possible to package goods that are greasy or release moisture.

[0041] It is also extremely advantageous according to the invention if the insert is designed to be liquid-tight at least with regard to the walls and base.

[0042] This also allows for liquid, free-flowing, moistening or greasy filling materials.

[0043] A further very advantageous development of the invention also exists if a reinforcing strip is arranged between two side walls, preferably adjacent to the front wall or the rear wall, preferably on the free edge of the side walls.

[0044] This stiffening strip can, for example, be designed as the "lid" of the packaging. The arrangement of the reinforcing strip not only stabilizes the free ends of the side walls, but also, if the reinforcing strip is connected to the front wall of the insert, prevents anyone from reaching behind the front wall during opening, which could potentially force the packaging open against the locking mechanisms. Additional reinforcing strips are conceivable.

[0045] Another very advantageous development of the invention is that the folding box is rectangular, trapezoidal, partially trapezoidal or the like in cross section and / or rectangular, trapezoidal, partially trapezoidal or the like in longitudinal section.

[0046] This makes it easier to remove the contents and / or prevents the contents from getting stuck in an edge.

[0047] Furthermore, it has proven very advantageous if the slipcase and / or insert are printed.

[0048] This can be used to add usage instructions, advertising, content information or the like.

[0049] In the following, the invention is illustrated using an embodiment.

[0050] Showing: Fig. 1 shows a blank of a slipcase, Fig. 2 shows a blank of an insert, Fig. 3 shows a diagram of the slipcase, Fig. 4 shows a diagram of the insert, Fig. 5 shows a schematic representation of the locking of the insert in the slipcase, Fig. 6 shows a blank of a slipcase with two locks, both locks being arranged in the rear area, Fig. 7 shows a blank of a slipcase with two locks, one lock being arranged in the rear area and the other in the front area, Fig. 8 shows a diagram of this slipcase and insert, Fig. 9 shows a blank of a package in which the rear wall runs at an angle, and Fig. 10 shows another blank of a package in which the rear wall runs at an angle and in which a cover is provided on the front wall.

[0051] With 1 is in Fig. 1 a blank for a slipcase with a base wall 2, a first longitudinal side wall 3, a top wall 4, and a second longitudinal side wall 5. The aforementioned sections are hinged to one another via fold lines 6. A closure flap 7 is also hinged to the free side edge of the base wall 2 via a fold line. With the help of this closure flap 7, the walls 2, 3, 4, and 5 are connected to form a sleeve.

[0052] At one end of the sleeve there is a bottom wall flap 8 on the bottom wall 2, a side wall flap 9 on the side wall 3, and a side wall flap 5 11 and a locking tab 10 is arranged on the top wall, which is folded onto the respective walls so that they lie inside the sleeve. The bottom wall tab 8 and the side wall tabs 9 and 11 are fully glued to the respective wall, thus reinforcing the respective wall so that it is stable and durable.

[0053] The side panel flaps 9 and 11 have a recess 12 at their edge facing the top panel 4, into which a corresponding projection of an insert that is pushed into the slipcase can engage. Because the recess does not extend to the fold line of the respective side panel 3 or 5, the maximum possible extension of the insert is limited, so that it cannot be pulled out of the slipcase or fall out of it.

[0054] In addition, a second recess 13 is provided on the side wall flap 11, which corresponds to the closure flap 7 and thus ensures that the wall of the slipcase is essentially flat on the inside.

[0055] The locking tab 10 is divided into two sections 15 and 16 by a fold line 14 arranged approximately halfway along the length of the top wall 4. The first section 15 is hinged to the top wall 4 by a fold line 17 and glued to the top wall 4. The second section 16, however, is not glued to the top wall. At the end facing away from the fold line 14, a taper 18 is provided. Within this taper 18, a fold line 19 is arranged parallel to the fold line 14. The position of the fold line 19 corresponds to the length of the top wall 4. Adjacent to the fold line 19 is an actuating tab 20, which is oriented toward the base wall 2 and has a grip hole 21.

[0056] At the rear end of walls 2, 3, 4, and 5, hinged rear panel flaps 22, 23, 24, and 25 are glued together when upright, forming the rear panel of the drawer. This rear panel features an elongated hole 26 corresponding to the handle hole 21, allowing access to the handle hole 21.

[0057] The elongated hole 26 is distributed accordingly over the rear wall tabs 22, 23, 24 and 25.

[0058] The second partial area 16 of the locking flap 10 hangs slightly down from the cover wall 4 with the fold line 19 when the slipcase is in the upright position. The tapering 18 thus forms shoulders 27 of the locking flap 10 which can engage in the insert.

[0059] The second blank 31 is intended to form the slipcase and consists of a base surface 32, a front wall 33 hinged via a fold line 37, a first side wall 34 hinged via a fold line 38, a second side wall 35 hinged via a fold line 39 and a rear wall 36 hinged via a fold line 40.

[0060] Gusset corners 41 and 42 are provided between the front wall 33 and the side walls 34 and 35, which seal the transitions between the front wall 33 and the side walls 34 and 35. For this purpose, the gusset corners are folded inward in this embodiment.

[0061] Between the side walls 34 and 35 and the rear wall 36, further gusset corners 43 and 44 are provided, which are also folded inwards so that a substantially flat surface is produced along the side walls.

[0062] The gusset corners 43 and 44 are shortened on the side walls 34 and 35, so that a locking tab 45 is hinged to each edge facing away from the base 32. When the insert is in the upright position, this locking tab 45 rests flat on the outside of the respective side wall 34 or 35. This locking tab 45 engages the recesses 12 of the drawer, which together limit the extension of the insert.

[0063] On the free edge of the front wall 33, a front wall flap 46 is provided, which in this embodiment is folded inwards onto the front wall 32 and glued to it.

[0064] At the free end of the rear wall 36, a recess 47 is provided into which the tapered portion 18 of the drawer can engage. The width of the recess 47 must therefore be identical to or slightly larger than the width of the tapered portion 18.

[0065] To reinforce the rear wall 36, a rear wall flap 48 is provided, which is folded inward and glued to the rear wall 36. The height of the rear wall flap corresponds almost to the height of the rear wall 36.

[0066] The recess 47 extends into the rear wall flap 48 and, when folded over, corresponds to the part of the recess 47 which is arranged in the rear wall 36.

[0067] When inserting the insert 51 formed from the blank 31 into the drawer 52 formed from the blank 1, the shoulders 27 hook onto the rear wall 32 of the insert 51. The insert 51 is thus held in a defined, fully inserted position.

[0068] The front wall 33 is flush with the front edges of the drawer 52 and does not offer any means of attack to pull out the insert 51.

[0069] Thanks to the reinforcing tabs, the walls are so stable that they cannot be bent to gain access to the contents of the packaging.

[0070] To open, the grip hole 21 is reached through the elongated hole 26 and the actuating tab 20 is moved toward the top wall 4. This also moves the shoulders 27 upwards and no longer hooks behind the rear wall 36. By applying slight pressure through the grip hole 21, the insert 51 is pushed at least slightly out of the drawer 52.

[0071] The grip hole 21 can now be released and the insert 51 can be pulled out of the drawer 52 as far as the locking tabs 45 allow.

[0072] The contents or part of the contents can be removed.

[0073] The insert 51 is then pushed back into the drawer. The shoulders 27 engage behind the rear wall 36, thus locking the insert 51 in the drawer 52.

[0074] This locking mechanism is extremely stable and also prevents the packaging from opening accidentally when held upside down.

[0075] In order to increase the opening security, the front wall 33 of the insert 51 can be arranged minimally recessed in the drawer 52.

[0076] Insert 51 and slipcase 52 are made of cardboard, although corrugated cardboard can also be used.

[0077] In Fig. 6 Another variant of a slipcase blank 61 is shown. This, in turn, has a bottom wall 62, a first longitudinal side wall 63, a top wall 64, and a second longitudinal side wall 65. The aforementioned sections are hinged to one another via fold lines 66. A closure flap 67 is also hinged to the free side edge of the bottom wall 62 via a fold line. With the help of this closure flap 67, the walls 62, 63, 64, and 65 are connected to form a sleeve.

[0078] At one end of the sleeve, a bottom wall flap 68 is arranged on the bottom wall 62, a side wall flap 69 on the side wall 63, a side wall flap 71 on the side wall 65, and a locking flap 70 on the top wall 64. These flaps are folded onto the respective walls so that they lie inside the sleeve. The bottom wall flap 68 and the side wall flaps 69 and 71 are fully bonded to the respective wall, thus reinforcing the respective wall in the area of ​​the open end of the sleeve, making it stable and resilient.

[0079] Because the side panel flaps don't extend the full length of the respective wall, the maximum possible extension of the insert is limited by the provision of corresponding abutment flaps on the interior. This prevents the insert from being pulled out of the drawer or falling out.

[0080] In addition, a recess 73 is provided on the side wall flap 71, which corresponds to the closure flap 67 and thus ensures that the wall of the slipcase is essentially flat on the inside.

[0081] The locking tab 70 is hinged to the top wall 64 by a fold line 77. A tapered portion 78 is provided at the end facing away from the fold line 77. Within this tapered portion 78, a fold line 79 is arranged parallel to the fold line 77. The position of the fold line 79 corresponds to the length of the top wall 64. Adjoining the fold line 79 is an actuating tab 80, which is oriented toward the bottom wall 62 and has two grip holes 81 and 81a.

[0082] At the rear end of walls 62, 63, 64, and 65, rear panel flaps 82, 83, 84, and 85 are hinged, which are glued together when erected and form the rear panel of the slipcase. This rear panel features an elongated hole 86 and a round opening 86a corresponding to the grip holes 81 and 81a. The elongated hole 86 allows access to the grip hole 81, which can be moved within the boundaries of the elongated hole 86. Thus, the second grip hole 81a aligns with the opening 86a, allowing the insert to be pushed slightly out of the slipcase with a finger through these corresponding openings.

[0083] When the slipcase is in the upright position, the locking flap 70 hangs slightly down from the cover wall 64 with the fold line 79. The tapering 78 thus forms shoulders 88 of the locking flap 70 which can engage with the insert.

[0084] A locking element 87 can be provided on the free edge of the closure tab 67, which is located laterally.

[0085] In variation of this, as in Fig. 7 shown, the second grip hole 86a must be moved to the side wall 62, so that a locking element of the insert must be unlocked here and additionally the locking tab 70 must be actuated via the elongated hole 86 in order to open the packaging.

[0086] The erected packaging is in Fig. 8 shown.

[0087] In Fig. 9 A variant of an insert is shown. Compared to blank 31, blank 91 has a shortened bottom wall 92. The rear edge of side walls 94 and 95 is therefore slanted. Sealing flaps 93 and 94 are adapted to this and designed as gusset corners. An additional fastening tab 98 is provided on the vertically extending part 97 of rear wall 96.

[0088] The angled back panel makes it easier to remove contents. The drawer can be adapted to this shape.

[0089] In Fig. 10 Another variant is shown. There, a flap 110 is additionally hinged to the front wall 33, which is folded onto the free edges of the side walls 94 and 95. Attached to the gusset corners 41 and 42 are fastening flaps 111 and 112, which are folded inward. The flap 110 is folded onto the fastening flaps 111 and 112 and connected to them. Depending on the width of the flap 110, the insert is thus covered by a "cover wall." This prevents the front wall 33 from being accidentally grasped or even forcibly opened.

[0090] It is conceivable that the material of the insert, but also of the slipcase, is equipped or coated in a liquid-tight, liquid-repellent, grease-proof, grease-repellent or similar manner, in particular that the insert is equipped on its inside with a resistance layer, in particular against liquids, wherein the resistance layer can be designed as a lacquer application, coating, impregnation or lamination.

[0091] The slipcase and / or insert may be printed and contain usage instructions, advertising, content information, or the like.
