Description

Hinged box and method and device for producing the same

Describe bunq:

The invention relates to a hinged box (Hi nge-Li d pack) made of (thin) cardboard, consisting of a box part 1 and a lid which is pivotally connected to a box back wall in the area of a lid rear wall via a linear joint, wherein In the box part 1 a collar is arranged, which is attached with lower fixing surfaces in the area of the collar front wall and collar side flaps to the inside of a box front wall or box side walls and whose area protruding from the box part 1 forms free visible surfaces . Furthermore, the invention relates to methods and apparatus for producing such hinged boxes.

Hinged boxes are designed as standard so that a collar is arranged in the box part 1, which protrudes with a partial area from the box part 1. This upper part of the collar is enclosed by the lid in the closed position of the hinged box. The collar consists of a separate blank, also made of (thin) cardboard, but can also be made in one piece with the (main) blank for box part 1 and lid be connected. In this case, the entire hinged box consists of a single blank.

In the case of the folding boxes which have been customary up to now, the collar is always continuously in white color or natural colors - corresponding to the color of the material for the collar. The folding box itself, on the other hand, is provided with colored printing on all sides in the area of the box part 1 s and the lid on the outside.

The invention has for its object to develop and improve hinged boxes with regard to the design white.

To achieve this object, the hinged manhole according to the invention is characterized by the following features:

a) the free, protruding from the box part 1 visible surfaces of the collar front wall and / or collar side flaps are provided with printing, namely with an ink layer applied to the visible surfaces,

b) the printing in the area of the collar front wall and / or collar side flaps is covered by a protective layer, in particular a lacquer or fi nis layer,

c) the protective layer or varnish or varnish layer extends over the entire area in the area of the visible surfaces of the collar front wall and / or the collar side flaps and ends in the area of an upper front closing edge formed by the box front wall or in the area of upper side closing edges formed by the box side walls, such that the fixing surfaces of the collar front wall and / or collar side flaps are free of protective layer or lacquer or varnish layer.

The invention enables printing of the collar that is flawless in terms of packaging technology. Preferably, only the areas of the collar protruding from the box part 1 are provided with such printing since the remaining areas are covered. An outer protective layer of lacquer or varnish that is customary in the case of such a depression is drafted version also provided only in the area of the collar protruding from the box part. According to the further findings of the invention, this makes it possible for the collar to be adequately or technically flawlessly fixed within the box by gluing. The surfaces to be provided with glue, namely fixing surfaces of the collar, are therefore, according to the invention, free of printing and also free of protective layers.

The invention can also be used particularly advantageously in the case of one-piece (total) blanks for hinged boxes. In this type of pack, the collar is expediently connected to the box part 1, in particular the front wall of the box, by Z-shaped rags or webs.

In conventional folding boxes with a collar made of a separate blank, the different surfaces of the collar, namely the printed and / or protective surfaces provided on the one hand and the fixing surfaces free of printing and / or protective layer on the one hand, are expediently in the area of a continuous web for the production of blanks for Collar applied. The cuts or punchings corresponding to the shape of the collar for separating the collars are then carried out - controlled by printing marks - in the area between successive visible surfaces and fixing surfaces of adjacent collars.

Another special feature is a device designed according to the invention for producing individual blanks for collars. In this case, a web of material, in particular made of thin cardboard, which is prefabricated with regard to the printing, is passed through a cutting device with at least one cutting roller, on the circumference of which a number of (cutting) knives is arranged in accordance with the contour of the collar. The distance between the knives is slightly larger than the corresponding dimension of a collar in order to compensate for movement differences between the material web and the cutting or knife roller.

The exemplary embodiments shown in the drawings relate to folding boxes or hinge-lid packs for cigarettes, cigarillos or other consumer goods. Such packaging consists of thin cardboard.

The basic structure results in particular from FIG. 2 and FIG. 5. The folding box then consists of a (lower) chess tei tei 1 10 and a lid 11. The box tei 1 10 of the overall cuboid packaging consists of a box front wall 12, an opposite box back wall 13, narrow, upright box side walls 14 and 15 and a bottom 16. Analog For this purpose, the lid 11 consists of lid front wall 17, lid rear wall 18 and lid side walls 19, 20 and an upper end wall 21. The box side walls 14, 15 and also the lid side walls 19, 20 are in this Embodiment of a hinged box formed in two layers, namely each consist of boxes -Sei tenl appen 22, 23 and lid -Sei tenlappen 24, 25. These side tabs extend approximately over the full width of the side walls 14, 15 and 19, 20 and cover each other. The side tabs 22..25 are connected to each other by gluing to form the side walls.

Box tei 1 10 and lid 11 are connected to each other, namely via a line hinge 26 in the region of lid-rear wall 18 on the one hand and box-rear wall 13 on the other hand. The line joint 26 allows the cover 11 to be moved between the open position (FIGS. 2, 5) and the closed position (not shown).

In the closed position, the cover front wall 17 bears against an upper front closing edge 27 of the box part 1 s 10. The front closing edge 27 is the upper transverse boundary of the box front wall 12. In the area of the box side walls 14, 15 oblique side closing edges 28, 29 are formed. These are the corresponding (trapezoidal) designed lid side walls 19, 20 in the closed position.

A collar 30, 31 belongs to the hinged box. This consists of a collar front wall 32 and collar side flaps 33, 34. The collar 30, 31 has a special geometric shape, namely with a recess 35 open at the top in the region of the collar front. wall 32.

The collar 30, 31 is fixed within the box part 1 s 10. The lower region of the collar 30, 31 dips into the box part 1 10. The collar front wall 32 lies against the inside of the box front wall 12. The collar side tabs 33, 34 are on the inside of the box side walls 14, 15. These surfaces of the collar 30, 31 form fixing surfaces with which the collar 30, 31 is attached to the inside of the box part 1 s by gluing. The surfaces of the collar 30, 31 protruding from the box part 10 form visible surfaces on the outside.

In an advantageous embodiment of a hinged box according to FIGS. 1 and 4, a one-piece blank is provided for the hinged box. The collar 30 is integrally connected to a main blank 36 for box part 1 10 and lid 11. The unity of the (total) cut is effected in the present case by webs 37, which act as residual connections. Outside these webs 37, the collar 30 is separated from the main blank 36 by punch cuts 38, 39. The die cuts 38, 39 also define the front closing edge 27 and the side closing edges 28, 29. The webs 37 are laterally delimited by separating cuts 60, 61. The webs 37 are therefore connected to the collar 30 on the one hand and the box front wall 12 on the other hand via transverse joints which ensure a Z-shaped fold.

1, the collar 30 is displaced relative to the main blank 36 with a Z-shaped fold of the webs 37. According to FIGS. 2 and 3, these are located on the inside of the front wall 12 of the box on while maintaining the connection to the collar 30. Outside the webs 37, the collar 30 lies in the usual way on the inside of the collar front wall 12 and can be connected to it by gluing. Likewise, lower areas of the collar side tabs 33, 34 lie against the inside of the box side walls 14, 15 (FIG. 2).

An important special feature is that the collar 30 is provided with a print on the outside, namely with an ink layer 40. This is identified by dots in the drawings. These surface areas of the collar 30, 31 are referred to below as visible surfaces 41. These visible surfaces 41, essentially the outer surface areas of the collar 30, 31 protruding from the box part 10, can be provided over their entire surface with an ink layer 40, but also with decorative printing or with content. borrowed information such as advertising, information, etc. It is also possible (additionally) to attach a legally required warning in the area of the visible surfaces 41.

The ink layer 40 in the area of the visible surfaces 41 is covered by an outer protective layer 42. This consists of a lacquer layer or a varnish layer of known composition. The protective layer 42 is usually glossy or high-gloss and protects the ink layer 40.

A special feature of the present collapsible boxes is the division of the front surfaces of the collar 30, 31. The areas of the collar 30, 31 lying within the box, that is to say hidden, of the collar 30, 31 have no printing, and accordingly are free of ink layers 40 and also free of Protective layers 42. The fixing surfaces of the collar to be described in detail are formed in a conventional manner in the area of the surfaces. These fixing surfaces are attached to the assigned surfaces of the hinged box with glue.

1, a strip-shaped fixing surface 43, 44 is formed in the region of the collar front wall 32 and the collar side tabs 33, 34, specifically adjacent to the box front wall 12 and to the (outer) box rows tenl appen 22. In the region of the collar front wall 32, a rectangular, strip-shaped fixing surface 43 is formed, including the webs 37. In the region of the collar side tabs 33, 34, the fixing surface 44 is designed in parallel with an elogram in accordance with the contour of the Collar 30 in this area. The width of the Fixierungsfl chen 43, 44 corresponds approximately to the immersion depth of the collar 30 in the box te 1 10. As can be seen from Fig. 2, the printed visible surface 41 is dimensioned so that it is slightly from the box front wall 12 or the box series tenwallen 14, 15 is overlapped.

A blank for a hinged box according to FIG. 2 can be produced rationally with regard to the design of the visible surfaces 41 and fixing surfaces 43, 44. In the flat state, the surfaces of the main blank 36 are printed in the usual way. At the same time or in the course of this work process, the visible surfaces 41 of the collar 30 are also printed and with the protective layer 42 provided delimiting the free fixing surfaces 43, 44. In the present exemplary embodiment, surfaces of the main blank 36 are also free of printing and protective layer, namely inside box side flaps 23 and inside lid side panels 24 and one in the finished folding box in Area of the end wall 21 of corner flaps 45.

A special feature is that the fixing surfaces 43, 44 have an edge strip 46 on the side facing the main blank 36. This is formed in the region of the collar 30 in continuation of a possible printing on the box front wall 12 and / or the box side walls 14, 15 or the outer box side flaps 22, that is to say with printing and optionally with a protective layer corresponds to the part of the hinged box. The edge strip 46 forms a tolerance range for technically given inaccuracies when making the die cuts 38, 39. It is to be ensured that in each case the box front wall 12 and the box side walls 14, 15 exactly up to the front closing edge 27th and have continuous printing on the side closing edges 28, 29.

FIG. 4 shows a blank for a hinged box, which largely corresponds to that according to FIGS. 1 to 3. In the area of the collar 30, an additional blank is integrally connected to the collar 30, namely a coupon 47. The coupon 47 is therefore made of the same material as the blank 30. The coupon is connected to the collar 30 via easily separable residual connections 48, specifically in the area the recess 35 of the collar front wall 32. The coupon 47 is formed in this area as a tongue 49 which projects into the recess 35 to fit. A foldable leg 50 connects to the tongue 49. When the hinged box is finished, the leg 50 extends in the plane of the end wall 21 or parallel thereto on the inside of the end wall 21.

When using this hinged box, the Coupon 47 can be easily removed. The hinged box is then given the conventional or described shape in the region of the collar. Coupon 47 can be provided with printing, lettering, information or advertising.

Fig. 5 shows in the open position a conventional folding box in which the collar 31 is formed from a separate blank (Fig. 6, Fig. 7). With regard to the printing of the collar 31, the procedure in this exemplary embodiment is analogous to the examples described.

As can be seen in particular from FIG. 6, the collar is provided with fixing surfaces 51, 52 in a lower region of both the collar front wall 32 and the collar side tabs 33, 34. These are designed in the manner described, that is to say free of printing (layers of color) and protective layer or lacquer. The untreated fixing surfaces 51, 52 are shown by hatching. In the area of the collar front wall 32, the fixing surface 51 extends approximately over half the height of the collar front wall 32. Above a dividing line 53, a visible surface 54 is formed which has printing, that is to say an ink layer 40, and an outer protective layer 42 or a layer of paint. In the region of the collar side tabs 33, 34, an oblique dividing line 55 is formed between the lower fixing surface 52 and the upper, trapezoidal visible surface 56.

Within the hinged box or the box part 1 s 10 (Fig. 5), the collar 31 with the fixing surfaces 51, 52 on the box front wall 12 and the box side walls 14, 15 is fastened by gluing. The rel ati vstellung of the collar 31 is selected so that the visible surfaces 54, 56 extend to an upper edge region of the box part 1 s 10, that is to say slightly below the front closing edge 27 and the side closing edges 28, 29.

A collar 31 designed in the sense of FIG. 6 can be manufactured in terms of process engineering in such a way that the blanks designed with a known, conventional contour are successively separated from a material web 57. The material web 57 consists of thin cardboard. Before the individual collars 31 are cut off, the outer surfaces of the collars 31 are prepared. In the area of the continuous material web 57, printing, ie Ink layers 40, applied to the collar front wall 32 and collar side tabs 33. Furthermore, the outer protective layer 42 or coating is applied in these areas. The hatched areas, that is to say the fixing surfaces 51, 52, remain free of printing inks and protective layers. For exact positioning of the dividing lines 53 and 55, the material web 57 is controlled by printing marks 58 in the area of a printing unit (not shown).

As can be seen from FIG. 7, the blanks of the collars 31 are separated with an edge strip 59 formed at the bottom, free edge. This is provided with a continuation of the printing on the next collar 31, including the outer protective layer. The edge strip 59 serves as a tolerance range for making a stamped cut 73 for separating the blanks for the collar 31. This ensures that an upper edge of the collar 31 always has the printing, in any case no pressure-free edge.

Of particular importance is a device for producing individual blanks for collars 31. FIG. 8 shows, as the most important part of the device, a cutting roller 62 or a section of a lateral surface thereof. The cutting roller 62 is provided along the circumference with knives 63 arranged at equal distances from one another. These are cutting edges which are shaped in the contour of the collar 31 and protrude beyond the outer surface of the cutting roller 62.

The knives 63 are arranged on the cutting roller 62 with (circumferential) distances 64 from one another, which are slightly larger than the corresponding lengths 65 of the collars 31. For example, the distance 64 of the knives 63 is 52.9 mm, while the corresponding length 65 of the Collar 31 is 52 mm. The reason for this is that the cutting roller 62 is driven at a slightly higher peripheral speed than the conveying speed of the material web 57. The difference in speed can be about 2%. To compensate, the larger distance between the knives 63 is provided in order to produce collars 31 of exact size. The cutting roller 62 is - depending on the diameter - equipped with seven or eight knives 63 along the circumference. The cutting roller 62 is part of a device as shown in an advantageous embodiment in FIG. 10. The material web 57, which is preferably drawn off from a bobbin (not shown), is conveyed by feed rollers 66, 67 at an exact speed. The material web 57, following the feed rollers 66, 67, comes into the region of a cutting unit 68. This consists of the cutting roller 62 described and a counter-roller 69 running along with it.

The cuts of the collar 31 separated in the area of the cutting unit 68 are grasped by subsequent conveyors, namely conveyor rollers 70, 71, and transported on at a higher speed. This gives the separated collar 31 a (larger) distance from the material web 57. Another conveying element, namely a driving lever 72, transfers the collar 31 to a preferably transversely directed removal conveyor (not shown), which feeds the collar 31 for further processing. This area can advantageously be designed in accordance with EP 0 324 160.

For the exact positioning of punch cuts 73 transverse to the material web 57 to separate the collars 31 (FIG. 7), the mode of operation of the device, in particular of the cutting unit 68, is controlled by the printing marks 58 on the material web 57. In the present example, a print mark reader 74 of a known type is attached above the movement path of the material web 57, here in the region of a deflection thereof by the feed rollers 66, 67. This controls the movement of the material web 57 in such a way that the punch cut. 73 is carried out at the exact position. For this purpose, the feed rollers 66, 67 are driven by a servo motor 75, which is connected to a central control unit of the packaging machine in terms of control.

The production of the blanks for the collar 31 in the area of the cutting unit 68 is matched to the machine cycle of the packaging machine. For this purpose, an organ is arranged in the area of one of the conveyor rollers 70, 71, which recognizes the respective position of a collar 31 after the separation. It is a so-called resolver 76, i.e. an organ, that recognizes the position of the blank based on the respective angle settings. The resolver 76 cooperates with the print mark reader 74 in terms of control. Overall, the control bodies 74 and 76 lead to a coordination of the (exact) production of the blanks with the machine cycle. Any deviations are compensated for by the servo motor 75 with the aid of the feed rollers 66, 67.
