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

[0003] However, plastic is problematic when it comes to disposal and recycling. One need only point to the plastic waste in the world's oceans.

[0004] 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.

[0005] 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.

[0006] This object is achieved according to the invention in that the folding box is designed in two parts, namely comprising a slipcase and an insert, wherein a locking device is provided which locks the insert in the slipcase, as defined in claim 1.

[0007] This prevents the slipcase from being pulled out without authorization and the contents are protected.

[0008] According to the invention, a bottom wall, a first side wall, a second side wall and a top wall are provided, which form a sleeve, wherein the sleeve is closed by a rear wall at one end thereof, and wherein the rear wall is formed from two or more rear wall tabs which are hinged to the bottom wall, side wall and / or top wall.

[0009] This creates a slipcase.

[0010] US 2017 / 0036808 A1 describes a child-resistant package with locking tabs and slots. The locking tab has memory properties that allow it to connect to and detach from the locking slot. The tab is made of corrugated material, and its memory properties allow it to return to the locked position after being bent against the direction of the corrugations. The locking tabs are positioned on the side of the slipcase.

[0011] US Patent 2020 / 0180808 A1 describes a sealable package comprising a tray insert, at least one locking tab of a folded portion of a panel or wall of the container, and an outer sleeve with a double panel or wall, wherein an inner panel or wall has at least one locking notch and an outer panel or wall has at least one locking tab. When the container is fully inserted into the sleeve, at least one locking tab, at least one locking notch, and at least one unlocking tab are positioned to lock and unlock the package.DE 10 2007 053 977 A1 describes a packaging made of a flat material, with a box-like packaging body, and at least one slipcase which partially encloses 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.

[0012] According to the invention, a locking tab is arranged on the side of the sleeve opposite the rear wall and is folded into the sleeve.

[0013] With the help of this locking tab, an insert can be locked and thus fixed in the slipcase.

[0014] According to the invention, the locking tab extends over the entire length of the sleeve and is provided with a projection which lies on the rear wall and has a grip hole.

[0015] This ensures that a locking mechanism is in place and that it can also be released easily.

[0016] According to the invention, it is 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.

[0017] This stabilizes the sleeve and gives it increased rigidity.

[0018] 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.

[0019] This also stabilizes the sleeve and gives it increased rigidity.

[0020] 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.

[0021] This allows the extension of the insert to be limited by a corresponding tab of the insert engaging in the recess.

[0022] Furthermore, it has proven to be very advantageous if the back wall has a handle hole.

[0023] This hole allows access to the locking tab. The hole can be designed as an elongated hole.

[0024] 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.

[0025] This locking tab is bent so that it rests on the side wall of the insert and engages with the recess in the side wall tabs of the drawer, thus limiting the insertion of the insert from the drawer. According to a further development of the invention, it is extremely advantageous to provide adhesive tabs on the side edges of the rear wall, the long side walls, and / or the front wall, which can be closed. These adhesive tabs also connect the individual walls of the insert to one another in a liquid-tight manner.

[0026] A further very advantageous embodiment of the invention is provided when a reinforcing flap is hinged to the front wall.

[0027] 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.

[0028] 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.

[0029] This also makes it possible to package goods that are greasy or release moisture.

[0030] 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.

[0031] This also allows for liquid, free-flowing, moistening or greasy filling materials.

[0032] Furthermore, it has proven very advantageous if the slipcase and / or insert are printed.

[0033] This can be used to add usage instructions, advertising, content information or the like.

[0034] In the following, the invention is illustrated using an embodiment.

[0035] Showing: Fig. 1 a cut-out of a slipcase, Fig. 2 a cut-out of an insert, Fig. 3 a diagram of the slipcase, Fig. 4 a diagram of the insert, and Fig. 5 a schematic representation of the locking of the insert in the slipcase

[0036] 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.

[0037] At one end of the sleeve, a bottom wall flap 8 is arranged on the bottom wall 2, a side wall flap 9 on the side wall 3, a side wall flap 11 on the side wall 5, and a locking flap 10 on the top wall. These flaps are folded onto the respective walls so that they rest inside the sleeve. The bottom wall flap 8 and the side wall flaps 9 and 11 are fully bonded to the respective wall, thus reinforcing the respective wall to ensure stability and durability.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] The elongated hole 26 is distributed accordingly over the rear wall tabs 22, 23, 24 and 25.

[0043] 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.

[0044] The second blank 31 is intended to form the insert 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Thanks to the reinforcing tabs, the walls are so stable that they cannot be bent to gain access to the contents of the packaging.

[0055] 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.

[0056] 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.

[0057] The contents or part of the contents can be removed.

[0058] 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.

[0059] This locking mechanism is extremely stable and also prevents the packaging from opening accidentally when held upside down.

[0060] In order to increase the opening security, the front wall 33 of the insert 51 can be arranged minimally recessed in the drawer 52.

[0061] Insert 51 and slipcase 52 are made of cardboard, although corrugated cardboard can also be used.

[0062] 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.

[0063] The slipcase and / or insert may be printed and contain usage instructions, advertising, content information, or the like.
