Abstract
Description
Field of invention
[0001] The invention relates to a packaging for objects. Background of the invention
[0002] Various types of packaging are known. The present invention relates primarily to packaging that has one or more compartments of varying sizes and shapes for holding objects. For example, GB 2 589 146 A discloses packaging according to the preamble of claim 1.
[0003] Such packaging was traditionally made of plastic. Efforts have already been made to avoid plastics in this type of packaging by simply substituting materials, for example, using thermoformed cardboard packaging or packaging made of fibrous, malleable material. The latter is often used, for example, as egg packaging.
[0004] However, these efforts were not satisfactory, as the usability of such packaging left much to be desired, especially for high-quality items.
[0005] The object of the invention is therefore to propose a cardboard packaging which does not have these disadvantages. Summary of the invention
[0006] This problem is solved according to the invention by designing the packaging as a tray which has one or more recesses for objects.
[0007] The items are stored safely in these recordings.
[0008] In this process, a flap is formed from a layer of cardboard, which together with another flap of a second, corresponding layer of cardboard forms a trough-shaped recess.
[0009] This creates a stable, trough-shaped recess for the safe storage of objects.
[0010] This arrangement of two corresponding layers of cardboard makes it possible to create stable and dimensionally stable recordings that retain their shape even without additional fastening means.
[0011] In this context, it is extremely advantageous if the flaps are bordered by grooves, scoring or cutting lines.
[0012] This precisely defines the flaps and also specifies fold lines around which the flaps can be folded or bent.
[0013] According to the invention, corresponding flaps each have a corresponding locking device.
[0014] This allows the flaps to be locked together and maintain the formed indentation even without adhesive.
[0015] It has proven particularly advantageous if the locking device is designed to have a single or multiple locking mechanism.
[0016] Depending on the size and desired stability, the locking mechanism can be designed accordingly. Additional bonding is also possible.
[0017] According to a further development of the invention, it is also extremely advantageous if one or more additional flaps are provided to define the recesses. These additional boundary flaps work together with the first flaps of the two cardboard layers and complete the trough-shaped recess.
[0018] It has also proven to be very advantageous if the first lobes and the subsequent lobes together form at least an approximately closed trough.
[0019] These additional flaps transform the recess into a complete recess. This prevents objects from sliding out sideways. Furthermore, the visual appearance is significantly improved.
[0020] The combination of the flaps of the first cardboard layer, the corresponding flaps of the second cardboard layer and the additional limiting flaps creates a comprehensive receiving system that offers both structural stability and optimal protection for the packaged items.
[0021] Furthermore, it has proven to be very advantageous if the two cardboard layers are formed from a cardboard blank that is folded by a fold line in such a way that the two cardboard layers are formed.
[0022] This allows for the use of a uniform cardboard blank, where the defined folding ensures that the individual flaps within the cardboard layers correspond to each other. Gluing these cardboard layers together is just as feasible as using independent cardboard layers that are then joined together.
[0023] Another very advantageous embodiment of the invention is provided when a third cardboard layer is arranged on top of the first two cardboard layers and completely or partially covers and / or closes the recesses.
[0024] A third layer of cardboard can be used to seal the individual recesses. It is also conceivable that individual cardboard sections could be placed on top of the recesses. Partial coverings are also possible.
[0025] It has proven to be very advantageous to provide flaps formed by cutting and / or scoring lines and / or scoring in the third cardboard layer.
[0026] These flaps allow for very simple and effective access to the objects in the recordings.
[0027] According to a further development of the invention, it is also extremely advantageous if it has a back-side cardboard layer.
[0028] This backing board layer forms a uniform and closed base. The openings are therefore inaccessible from the back. The backing board layer can also have side walls, thus connecting it to the other cardboard layers of the packaging.
[0029] Another very advantageous embodiment of the invention exists when an outer packaging is provided to hold the packaging.
[0030] In this process, the packaging is inserted into an outer packaging, thus replacing plastic inlays or trays.
[0031] According to a further embodiment of the invention, it is also very advantageous if the flaps and the further flaps are designed in such a way that they can be raised by simply pressing down and thus form the troughs.
[0032] This makes it very easy to produce the troughs.
[0033] It has proven to be very advantageous if the lobes and the further lobes are designed in such a way that several or all of them can be erected simultaneously.
[0034] This allows several or all troughs to be formed in a single step by pressing down the flaps and subsequent flaps. This process is very easy to automate.
[0035] A particularly advantageous use of the packaging according to the invention is when the packaging is intended as a chocolate box, advent calendar or the like.
[0036] These types of packaging are designed as single-use packaging and contain a high proportion of plastic. This plastic will be replaced. Drawings
[0037] Fig. 1 a cardboard blank for a packaging according to the invention, Fig. 2 the cutting in the first processing stage, in which an initial fold was made, Fig. 3 the erected packaging, formed from the cut-out seen from below, Fig. 4 the same packaging seen from above Fig. 5 a top view of the infested packaging, and Fig. 6 A diagram of a package that can be closed with flaps, where part of the flaps are open. Detailed description of the embodiments
[0038] The invention is illustrated below by means of several exemplary embodiments.
[0039] With 1 is in Fig. 1 A cardboard blank for packaging.
[0040] A fold line 2 divides the cardboard blank into two equal halves 3 and 4. Deviations in the size distribution are conceivable.
[0041] In the first half 3 of the blank, flaps 5 are formed by cutting lines 6 and a fold line 7. At the end of the flaps 5 pointing away from the fold line 7, a locking device 8 is provided, which essentially consists of a locking lug 9 and a locking device 10, which is arranged on the flap 5 via a fold line 11.
[0042] The five cloths can be of different sizes. The sizes depend on the items to be packaged.
[0043] In the second half 4 of the blank 1, counter flaps 12 are provided, which are also bounded by cutting lines 13 and a fold line 14. In this embodiment, limiting flaps 15 are provided along the cutting lines 13. In addition, a corresponding locking device 16 is provided at the end of the counter flaps 12 pointing away from the fold line 14, which is capable of engaging in the locking lugs 9.
[0044] If the two halves 3 and 4 are folded together along fold line 2, the flaps 5 and 12 are unfolded and the locking devices 8 and 16 are engaged. Additionally, the limiting flaps 15 are folded in the opposite direction to flaps 5 and 12. The limiting flaps 15 are hinged to flaps 12. However, it is also conceivable that the limiting flaps, like flaps 5 and 12, are folded into the recess and thus in the same direction as flaps 5 and 12. In this case, the limiting flaps 15 are hinged to the cardboard layer 4.
[0045] The flaps 5, 12, and 15 together form a recess into which items to be packaged can be placed. The limiting flaps 15 prevent the items from sliding out laterally. The interconnected flaps 5 and 12 hold the items in place.
[0046] The flaps 5 and 12 are interlocked. However, it is also conceivable that they may additionally be glued or otherwise connected to each other.
[0047] To erect flaps 5, 12, and 15, it is usually sufficient to simply press them down. They will lock into place automatically.
[0048] This allows not only the formation of a single indentation, but also the formation of several or all indentations of a package in a single step.
[0049] For certain items to be packaged, it may be possible to dispense with the limiting flaps 15 entirely or partially.
[0050] In Fig. 6 This shows a variant where the top side, i.e., the
[0051] Folding of flaps 5 and 12, on the cardboard side of the packaging facing away from the outside, a further cardboard layer 61 is provided, which can cover the surface completely or partially.
[0052] In this cardboard layer 61, flaps 64 formed by scoring lines 62 and folding lines 63 are provided, which are arranged corresponding to the recesses formed by the flaps 5 and 12.
[0053] These flaps 64 can be folded forward, for example, by tearing open the scored lines 62 around the fold lines 63, thus opening the recess. The packaged item can then be removed.
[0054] It is conceivable that an opening aid 65 is arranged on the flaps 64, which may be designed, for example, as a recess, protrusion, pressable area or the like, and which facilitates the opening of the flaps 64.
[0055] Furthermore, it is also conceivable that the reverse side of the packaging formed from the cutout 1, i.e. the side towards which flaps 5 and 12 are folded, is provided with a cover, which may also be made of cardboard.
[0056] The resulting side edges can also be made from cardboard.
[0057] It is conceivable that the individual layers are formed separately or wholly or partially from a single cut.
[0058] Printing may be provided on the outside of the layers.
[0059] It is conceivable that the packaging could be used, for example, as an advent calendar or as an inlay for chocolate packaging, thus replacing plastic inlays.
[0060] The packaging according to the invention is therefore sustainable and environmentally friendly. Further applications are conceivable.
