Cardboard foldable box.

p0001The invention relates to a folding box made of cardboard according to the preamble of claim 1.

p0002Such cartons are used for packaging, inter alia for wet wipes, etc., and must be designed so that they can also serve as donors. That is, they have besides a pleasing appearance have sufficient stability that is necessary so that also can be easily removed from the pack the last towel. Furthermore, such cartons to ensure adequate protection against drying of the wipes.

p0003In the European patent application 89 117205.8 a Faltschachtelverpackung of the aforementioned type is described, corresponding to the requirements just mentioned quite well. This known carton is either provided internally with a plastic or aluminum coating or it is made of an aluminum multilayer composite, which preferably has a sequence of layers of polyethylene, cardboard, polyethylene, aluminum, adhesive and polyethylene from the outside inwards. The removal opening is located directly in the box top and is sealed by an adhesive closure. A disadvantage of this embodiment, however, is the one the problematic disposal, the results from the different composite materials. On the other hand tends to pack again open for undesirable rapid desiccation of the cloth, as a separation or isolation between the box interior and the outside world only serving the torn perforation defining the removal opening, abdekkende adhesive sheet of the closure flap.

p0004In a second embodiment of the known folded box an inner body is provided in the form of a tubular bag made of a plastic. The folding box itself is made of cardboard. Since in this embodiment the access to the remaining towels is more difficult in an advanced emptying of the tubular bag, the tubular bag is adhesively bonded in the region around the discharge opening around fixedly connected to the folding carton. This means, however, that here there is almost a direct access from the interior of the tubular bag to the surroundings. It is thus to be expected also in this embodiment with a faster drying of the wipes.

p0005Another disadvantage of this embodiment is that also again Entsorungsprobleme occur due to the bonding of plastic bags and cardboard. In addition, the manufacture of such packaging is complicated and technically complex, since the same time, the cloths must be packaged in the same in the production of the tubular pouch, immediately followed tubular bag and carton have to be bonded.

p0006Finally, a good handling of such packaging is not necessarily guaranteed to the end, because the fact that the user has to reach into deeper into the tubular pouch at any cloth, it is not excluded that, due to mechanical overloading, so the fact that during the removal with the carton glued tubular bag top is continually pushed, the tubular bag separates from the outer carton, allowing access to the wipes is further complicated.

p0007The invention is therefore based on the object, a folding box of the type mentioned in such a way that both their preparation and their handling and disposal easier.

p0008The invention solves this problem by means of the features of claim 1.

p0009Further advantageous embodiments of the invention are subject of the dependent claims.

p0010Characterized in that the inner body of the folding box is a soft hollow insert that is made for example by deep drawing from an environmentally compatible plastic sheet, but the folding box consists of a simple box, the disposal of the emptied package is much less problematic than that of the known folding cartons. Even the consumer can separate waste according to cardboard and plastic content easily, so that the plastic part can be re-used while the Pappa part is thrown in the waste paper container and is thus also supplied for reuse. The soft insert tray rests in the outer carton. Alone by the relative rigidity of the soft hollow insert is ensured that the opening in the cover of the soft tray insert also is easily accessible even if only a few towels are provided in the package.

p0011Moreover, the production of the article according to the invention is simpler than that of the known from the prior art cartons. The folding box made of cardboard and the soft hollow insert can be prepared separately from each other, wherein the soft hollow insert together with the cover and filling can be completely manufactured. He then only needs in the pre-folding box to be inserted, which is then closed.

p0012The fact that not only the actual removal opening is closed in the cover of the soft hollow insert with the tongue-shaped flap, but also the carton itself by the folding area in the upper side, the resulting flap with its front end, for example, in a slot-shaped opening at the front of folding box can be inserted and thus be locked, the speed of drying of the wipes is already reduced.

p0013According to the feature of claim 2 of the inner body is stabilized due to the flange-forming, which in particular accommodates an easy removal.

p0014In conjunction with the feature of claim 3, this particular configuration of the inner body edge has the further advantage that the inner body can rest safely and practically immovably on the bearing edge formed by the Faltschachtelränder. But even if the flange-like rim is bonded to the support surface to prevent slippage of the inner body in the carton even safer, an unproblematic disposal is still ensured that the adhesive surface is relatively small, whereby the separation of the inner body and carton easily feasible is.

p0015As a result of the above, the actual dump body does not need to consist of a thick, stiff plastic, but may be made of a relatively thin-walled, problem to be disposed of film.

p0016To further enhance the operability of the folding box according to the invention, in particular to avoid an occurring during the storage period of the carton premature drying of the wipes, suggests the claim 4 provides that between the filling and the bottom of the inner body cover, an insert sheet is provided which overlaps the removal opening , This additional page may be located in the inner body loose. It is removed from the package after the first opening of the packing before the removal of the first wet wipe.

p0017However, it is also possible to leave the insert sheet either fixed or loose permanently in the inner body. However, this presupposes according to claim 6, that is provided in comparison with these smaller punched in the sheet inserted in the region of the removal opening. Given the above, it is of course advantageous if this insert sheet is attached to the lid of the inner body, so that the remaining wipes are still easily accessible.

p0018According to a further advantageous embodiment of the invention, the edge of the smaller punched is provided with radially facing away from the edge cut lines that end before the edge of the removal opening.

p0019These punch lines bring the advantage of using the folding box with that the deposit with the engagement in the package yields, since the edge is now much more flexible. In this way, the towels can be found much easier. In addition, the thus notched edge in the removal of the cloths forms a guide for the same, so that the contact of the wet wipes is avoided with splices on label and foil.

p0020According to the feature of claim 8, the punching is formed by a perforation. In this way it is possible to keep up to the first use of the carton not only the box itself, but also the soft trough use virtually leakproof. After first opening the carton, the punched-out along the perforation is cut out of the loose-leaf.

p0021according to claim 9 the insert sheet is advantageously a plastic film, for example, a PE film.

p0022The insert sheet has the additional advantage that during the storage time of the folding box no moisture, for example water, but also oil into the area of ​​the dispensing opening can pass defining perforation. Thus, premature drying of the contents or softening and Unansehnlichwerden the carton is virtually impossible.

p0023Advantageously, the inventive folding box with the features of claim 10 is combined, which are known for already known from European Patent Application 89 117205.8. The advantages of such a closure for the removal opening resulting from this application.

p0024In the following the invention is illustrated with reference to several embodiments and described in more detail.

p0026In the figures, the folded box according to the invention is generally designated by the reference numeral first It consists of a parallelepiped container 2 made of cardboard. The container consists of a bottom surface 3, ascending side walls 4, 5, 6 and 7 and a cap surface 8, which is folded and glued on the front side surface 7th In the top surface 8 of a rectangular perforation 9 is provided, which continues trapezoidal on the front side surface 7th The trapezoidal portion 10 is not adhered to the side surface 7, so that this part along the perforation, and then can be further torn along the perforation lines 11 and parallel 12th This results in a flap whose front tapered section 13 forms a flap in the front side wall 7 can be inserted into a corresponding slot 14th

p0027. As can be seen from Figure 2, the side surfaces 4 and 6 are designed as follows: Along the edge 15 of the carton is folded by an angle of 90 ° inwards and furthermore along the edge 16 to the bottom 3 of the container 2, so that below the lid surface 8 each have a bearing surface gives 17, which is supported by the folding legs 4 and 18 at the bottom of the third On the bearing surfaces 17 rest inside the folding box 1 an inner body 19, which consists of a one-piece trough-shaped part 20 and a lid 21st The upper edge of the trough-shaped part 20 is bent horizontally, so that a flange-like edge 22 results, on which the cover 21 is fixed (adhered, verschlweißt) is.

p0028Fig. 3 shows in addition to Figures 1 and 2, the dispensing opening 23 which is defined by the perforation line 24 in the lid 21. The perforation line 24 is not closed in itself, but executed in the form of a U, the free legs extend 25 and 26 curved inward. this removal opening is overlapped 23 by a strap 27 which is fixedly connected to the U-shaped discharge opening shutter and self-adhesive but removably the removal opening 23 adheres to the surrounding area lid. The flap 27 is fixedly connected in the region of the arcuate U-leg ends 25 and 25 with the lid 21 of the inner body 19, for example by gluing, welding etc ..

p0029The FIG. 4 shows the folding box according to FIG. 3, but which is torn in this embodiment along the perforation 11 and 12, so that a hinged lid gives 28th After lifting the lid 28 of the closure of the removal opening 23 is accessible. Once the tab 27 is lifted off the lid 21, tearing the perforations 24 to the arcuate ends 25 and 26th After a cloth has been removed, the flap 27 is again glued to the lid 21, wherein the along the perforation line 24 torn part of Decksl 21 inserted into the removal opening 23 accurately. Thereafter, the flap 28 is folded down and put the trapezoidal tapered end 13 of the flap into the slot 14, so as to provide a reliable closure of the folding box.

p0030In Figs. 5, 6 and 7, the same parts as in the preceding figures are provided with the same reference numerals. The embodiment of FIG. 5 differs from the embodiments discussed so far in that an insert sheet 29 is provided in the inner body 19 between the filler material and the cover 21 in the region of the removal opening 23. This insert sheet is preferably a plastic film which is entommen after first opening of the pack and has the only task is to protect the carton during prolonged storage prior to drying.

p0031Another embodiment of the invention, FIG. 6, in which an insert sheet is also 29 'are provided. Unlike the embodiment shown in FIG. 5 of this insert sheet has concentric with the discharge opening 23 on an oval punched 30, so that this insert sheet 29 'can also remain in use the carton in the pack. Thus it becomes more empty the inner body, the level of punching and thus the actual removal opening 30 does not decrease and a removal of the last towels not practicable, it may be provided that the insert sheet 29 'is adhered to the underside of the lid 21st

p0032In FIG. 7, the embodiment of FIG. 6 is shown with open flap 28.

p0033In Figs. 8 to 10 respectively is shown in the section of the removal opening area of ​​the alternative embodiments of the invention. Thus, FIG. 8, the embodiment shown in Figures 1 to 4, wherein below particular carton flap 28 the adhesive flap 27 is shown, which is releasably adhered at their edges on the lid 21 of the inner body. The removal opening 23 itself is closed in the representation by a punch cut 31, which remains when pulling the tab 27 at this stick and is separated from the lid 21st

p0034The Fig. 9 differs from Fig. 8, characterized in that an existing plastic insert sheet 29 is provided between the stack of wet wipes 32 and the lid 21.

p0035A similar structure resulting from the FIG. 10, in which the insert sheet by reference numeral 29 'is provided, since it is of the insert sheet 29 differs in that concentrically one cut 30 is provided for the removal opening 23.

p0036Another embodiment of the invention is shown in FIG. 11. Again, the carton is shown with the flip open 28th The punching section 31 is also open, so that the removal opening 23 is free. As shown in Fig. 6, an insert sheet is also here 29 'is inserted, which has an oval punched-thirtieth Unlike the embodiment of FIG. 6 to go with this punch-30 from the rim 40 radially outwards punch serving lines 41. These punch lines indicate when using the package, ie the engagement in the pack after, so that the cloths can be much more easily removed. When extracting the towels of notched, more compliant rim 40 forms a guide and a protection, so that the contact of the wet wipes is avoided with splices on label and foil.

p0037In FIG. 12, the folding box 1 in FIG. 11 is shown in closed condition. In this state, the punching 30 is still closed. The edge 40 of the punching 30 is still formed by a perforation. Only after the first opening of the folding box 1, the punching is removed along the perforation 40th This configuration is the loss of its contents, in particular oil, avoided before the first opening. This leakage is particularly feared improper storage.
