Definitions
- the invention relates to a carton for dust and insect-proof packaging of a one-piece, foldable blank from which a cuboid box can be produced by folding, which has internal Faltecken at all box corners, the box on two sides in each case by two opposite sides of the Box hinged flaps can be closed.
- the invention also relates to a method for tightly closing such a folding box.
- Folding cartons are used on a large scale for automated, fully automatic packaging of all kinds of products. These have some outstanding advantages over competing plastic packaging, especially pouches. Folding cartons are made from a cost-effective, versatile and environmentally friendly material. The boxes can be provided in the most diverse designs and very well machined, for example by coating, painting or printing. The possibility of palletizing, the mechanical protection against external influences as well as the problem-free recycling and recycling in the applicable recycling system are advantages of folding cartons. State of the art
- a folding box is known from a one-piece, foldable blank, from which a cuboid box can be produced by folding is that has at each box corners inside Falt ⁇ corners.
- the box can be closed on two sides by two closing flaps hinged on opposite side parts of the box.
- the two flaps are identically dimensioned so that they close each half of the page.
- the inner corners make it possible to achieve a high level of tightness at the box corners.
- the two flaps form a joint line and thus a gap that can be reasonably sealed only with an adhesive strip.
- the object of the present invention is to provide a carton for an insect and dustproof packaging, which has a high
- Claim 7 indicates the associated method for insect and dust-tight sealing of this carton.
- Advantageous embodiments of the carton and the method are the subject of the dependent claims or can be taken from the following description and the persons ⁇ examples.
- the present carton for dust and insect-proof packaging consists in a known manner of a one-piece, foldable blank, from which a cuboid box can be produced by folding, which has inside corners at all carton corners.
- the box can be closed on two sides by two closing flaps articulated on opposite side parts.
- An example of the basic structure of such a box is a carton according to FEFCO code 0226.
- the present carton is distinguished by the fact that of the two closing flaps, a first closing flap completely covers the side and the second closing flap only partially covers the side, and that the folding corners and the second Closing flaps along the so ⁇ parts to which they are hinged, each provide a continuous adhesive surface for applying adhesive, which allows a closed bonding of the entire edge of the first flap when closing the box.
- the folding corners are in the case of the present FaIt- box on the fully covering flaps not in the full length Ll executed, as this would lead to a Materialauf ⁇ coating when folding the flaps by folding the Faltecken over the length L2 of the narrow flaps.
- This material stratification can produce errors in the fully covering gluing of the folding corners, since then the fully covering flaps with the length L1 do not lie perfectly flat on the narrow closure flaps with the length L2. As a result, unwanted channels can be formed into the interior of the box.
- the folding corners on the fully covering closure flaps are therefore shortened or cut by at least the longitudinal length L2 of the narrow closure flap.
- the fold corners on the narrow closing flaps thus each only extend to a distance from the side part which is smaller than or equal to the length difference L1-L2 between the fully covering and narrow ones Shutters is. This allows a completely flat edge bonding of the closing flaps and folding corners.
- the small width of the second flaps which is preferably less than half the width of the first flaps, allows for the synchronous closing of the two opposed flaps, which is required due to the rigid connection of the flaps over the folding corners.
- the optimum width of the narrow closure flap is determined essentially by the band or packaging speed with which the cartoning plant operates.
- the closing of the carton is advantageously made possible by a simple adhesive application, which requires no complex, specially controllable nozzle strips.
- Adhesive surfaces can be applied to the hot melt adhesive by applying a disk or using a few nozzles. In this case, any desired slot, spray or bead application nozzles can be used as nozzles.
- Essential in this adhesive application is only that the hot melt adhesive when closing continuously covers the entire edge of the fully covering flap. In this way, an all-round closure of the entire gap between the fully covering flap and the side panels is achieved. An additional inner bag is no longer necessary. Due to the simple adhesive application by means of a disc or with only a few, preferably a maximum of three, adhesive nozzles, a significantly lower adhesive consumption is achieved than with the Sift Proof technique described above.
- the present carton thus enables cost-effective, dust and insect-proof packaging. Furthermore, the use of the present folding box for packaging does not require any elaborate conversion measures of existing cartoning machines at the glue station.
- Cartoning machines equipped with conventional gluing units vertical technology
- the format-related output of existing cartoning machines can be kept constant.
- An optional in-line quality control of the folding carton production process focuses on the exact timing and placement of the pasting on the intended adhesive surfaces in the present folding carton. This eliminates an additional, metrologically complex quality control, as required for example in the Sift proofing technique.
- the present carton is preferably as a standard carton (in contrast to special or Special forms of cartons) trained and corresponds to a basic type of carton.
- Standard cartons are all box shapes described in the ECMA (ECM: European Carton Makers Association) Code.
- the joints of adjacent folding corners do not extend to the edge of the side part or the so-called creasing edge, but have a minimum distance therefrom in order to ensure a reliably tight cardboard connection.
- This minimum distance preferably corresponds to the width of the adhesive surfaces provided.
- the folding corners are provided with scoring edges, which in one embodiment do not extend to the side part or the scoring edge, for example, have a minimum distance of at least 4 mm from the inner corner, to cardboard breakthroughs during folding avoid.
- the scoring edges may extend directly to the inner corners, in which case, however, a first section which extends to a minimum distance from the inner corner has a greater scoring depth than the remaining section, which extends as far as the inner corner extends. Due to the smaller depth of the scribe edge in the remaining section, a cardboard puncture at the corners can likewise be avoided.
- Fig. 1 shows an example of the one-piece blank of the present carton
- Fig. 2 shows an example of the embodiment of the scoring edges of the folding corners of the present folding box
- Fig. 3 shows schematically the adhesive steps for the closure of the carton (horizontal
- Fig. 4 is a perspective view of the erected carton during the closing of the flaps.
- FIG. 1 shows an example of a punching die for producing the present folding box.
- the one-piece blank shown in the figure is composed of the interconnected side parts 10, where the eight folding corners 1 and the closing flaps 2, 3 are articulated via creasing edges 8.
- a side panel of the carton is replaced by the two
- the side flap 4 is in present example as adhesive flap already provided with an adhesive layer. This can be done by Vorklebung the blank.
- the respective unequal closure flaps 2, 3 can be seen very well.
- the large flaps 2 are dimensioned to just completely cover the side of the carton they are closing.
- the narrow closing flaps 3, which are opposite this in the erected folding box, are dimensioned so that the mechanical closing operation after pasting can run synchronously and smoothly.
- By covering the two flaps 2, 3, a joint line is avoided when closing the carton.
- the full coverage of one of the flaps allows a simplified application of adhesive when closing the carton, which can be done for all adhesive zones of a page at the same height or in the same plane.
- the adhesive surfaces 6 are formed both on the narrow closure flaps 3 and on the folding corners 1 continuously along the side parts 10, on which the closure flaps 3 and the folding corners 1 are articulated.
- the joints of the folding corners lie in a minimum distance a above the creasing edges 8 of the side parts 10. This distance corresponds to the width of the adhesive surfaces 6 provided.
- the folding corners 1 are provided with scoring edges 7, which are formed in the present example as shown in FIG.
- the scribe edge is divided into two sections. In a first section 7a spaced from the inner corner, this scoring edge has a normal scratching depth. In the remaining section 7b only a minimal scratch depth is used to avoid cardboard breakthroughs during folding.
- the second section 7b can no longer have any scribe edge.
- the distance of the first portion 7a from the inner corner is at least 4 mm.
- the sealed closure is carried out by the indicated in Figure 3 with the arrows adhesive steps.
- the figure shows the folding box 12 after Auf ⁇ judge and before the folding of the corners and closure flaps from above. For gluing on the in the
- Figure 1 illustrated adhesive zones 6 with the three nozzles 11 applied a hot melt adhesive, which are arranged for this purpose at the same height.
- a two-stroke bonding is shown, in which the individual cycles of each order of the
- Adhere to adhesive Adhere to adhesive.
- the distance between the hotmelt adhesive and the creasing edge is defined by the compression of the hotmelt adhesive, in particular its viscosity, the contact pressure and the suction behavior of the folded box, when the closure flaps are pressed.
- Closure bonding of the upper side and the lower side of the folding box 12 may be intermittent or clocked to "gap".
- nozzles can Contact nozzles or spray nozzles are used. It is also possible to apply the hotmelt adhesive to a pane.
- the flaps and the fold corners located on this side are inserted synchronously and pressed until the adhesive has cured.
- the concept of the present carton allows with appropriate positioning of the glue station both a vertical and a horizontal filling of the cartons.
- FIG. 4 again shows a perspective view of the erected folding box 12 during the insertion of the closing flaps 2, 3 and folding corners 1.
- the fully covering closing flap 2 opposite the narrow closing flap 3 and its connection via the folding corners 1 with the scoring edges 7 are very good in this illustration to recognize.
