Description

The present invention relates to a stackable blank, as well as boxes made from it, which, in particular, are used as packages for cigarettes.

Cigarettes are usually delivered to the market either in soft box containers or in rigid box containers, for example, in boxes with a hinged lid or boxes with a hinged lid, but also in a hard-soft container without a hinged lid. In the case of rigid boxed containers, rounding corners and edges are also known, thereby protecting the pockets of consumers. For example, in ΌΕ 2940797 A1, for this purpose, a cigarette box is described, including a hinged lid, in which all corners and edges are rounded. However, this German application has not disclosed how this box can be made.

EP 0764565 A1 describes a cigarette box with a hinged lid, with four orthogonal main edges chamfered or rounded. For the manufacture of such edges are also shown corresponding folding blanks. This European publication also contains reference to patent I82523251 (lines 51-54 in column 4 of document EP 0764595 A1) and thus to a combination of rounded or beveled horizontal edges according to EP 0764595 A1 with bevelled longitudinal edges according to I82523251. However, in this case there is no indication of how this embodiment can be made.

In fact, making a box, especially a box with a hinged lid for cigarettes, in which all corners, as well as the longitudinal edges and horizontal main edges are rounded or beveled, from a single foldable blank, causes problems.

Therefore, it is an object of the present invention to provide a foldable blank produced in a simple manner for producing a box, in particular a box with a hinged lid for cigarettes, in which all longitudinal edges and horizontal main edges, as well as corners, are as much as possible substantially rounded or chamfered.

The solution of this problem is provided by the folding blank made of the folded material to form a box in the form of a rectangular parallelepiped, which is closed on at least five sides, with two diametrically opposite platforms of the main faces of the formed box in the shape of a rectangular parallelepiped and the bottom platform connecting them in the folding blank is arranged straightforwardly one after another, and the sides, which in the manufactured box in the shape of a rectangular parallelepiped fit to both diametrically opposite The underlying areas of the main faces and the bottom connecting area are formed by side edges that extend to both sides of the main faces, and the edges of both lying diametrically opposite to the areas of the main faces that are made in the box in the form of a rectangular parallelepiped are different that two bend areas meet with each other in (preferably the bottom) corners of both lying diametrically opposite in the box to be made in the shape of a rectangular arallepiped areas of main faces, and from two (preferably, essentially orthogonally) meeting each other bend areas, one is limited by a circular arc segment of about 45 to 90 °, preferably 65 to 80 °, and the other is limited to an 8-shaped curve, with 8 a shaped curve in the corner of the areas of the main faces is adjacent to a segment of the arc of a circle, and the fold areas are preferably provided with two or more adjacent, essentially parallel fold lines, respectively.

Preferred is a certain, above folding workpiece with the first platform of the main face with the left and right first platform of the side face, with the bottom edge of the first edge of the main face adjoining the bottom platform, and the second edge of the main face of the left and right second pad adjoining the top edge of the bottom platform the lateral face, the folding blank has horizontal and vertical fold areas, namely the first and second horizontal fold areas between the first main edge area and the bottom area, and the same bottom area and the second platform of the main face, and the first to fourth vertical fold areas between the left first side face area and the first main face area, the first main face area and the right first side side area, the left second side face area and the second main face area as well as the second pad of the main face and the right second pad of the side face, the first horizontal bend area in the upper corners of the first pad of the main face meets the first and second horizontal faces Strongly crease, the second horizontal fold area of the bottom corners of the second pad main faces meets the third and fourth horizontal fold area.

The above-described folding blank can be made in a simple way by a corresponding change in the existing machines for the production of folding blanks. By means of usual bending and gluing, rigid box packaging is obtained from it, which consists only of a box-shaped part into which a packet of cigarettes is put, packed in an inner wrapper. Usually the size of the box is such that a pack of cigarettes is tightly placed in the box and protrudes at the upper open end to allow the consumer to open the box and take out the cigarettes.

As a rule, the box has, however, along with the box-shaped part, also a lid part, so that the result is a regular box with a hinged lid.

To obtain such a conventional box with a hinged lid, the above-described folding blank has additional platforms, namely, the third platform of the main edge adjoins the second pad of the main face with the left and right third pad of the lateral face, and the pad of the upper side adjoins the upper edge of the third pad , and the fourth edge of the main face with the left and right pad of the side face adjoins the upper edge of the upper side platform, and the folded billet has additional mountains horizontal and vertical fold areas, namely the third and fourth horizontal fold areas between the third main edge area and the upper side area, as well as the upper side area and the fourth main edge area, and from fifth to eighth horizontal bending areas between the left third side edge area and the third pad of the main face, the third pad of the main face and the right third pad of the side face, the left fourth pad of the side face and the fourth pad of the main face, and also the fourth the side of the main face and the right fourth pad of the side face; the third horizontal fold area in the upper corners of the third pad of the main face meets the fifth and sixth vertical fold areas, and the fourth horizontal fold area at the bottom corners of the fourth pad of the main face meets the seventh and eighth vertical fold areas .

Preferably, the folding blank, in addition to the described areas, additionally has on the lower edges of the left and right second areas of the side faces the left and right second end inlet of the side edge area and also on the upper edges of the left and right third sides of the side faces side faces. These end inlets of the sides of the side edges serve to reinforce the bottom and the cover of the finished box.

In a preferred way, on the upper edge of the fourth pad of the main face there is a reinforcing pad, which, when making the box, is glued on the inner side of the fourth pad of the main face and also serves to reinforce.

Conventional materials used for making boxes with hinged lids, such as paper or cardboard, as well as plastic, plastic film or laminated plastic, preferably paper with a wide web or cardboard with a wide web, can be used as a folding material.

Fold lines can be corrugations or, preferably, notches, preferably extending along the entire length and width of the box.

For the manufacture of grooves on the folding billet in the appropriate places presses the device for grooves. On the opposite side there is a groove in the grooves into which the material of the folded billet can be pressed. With parallel grooves in accordance with the described method, a wave-shaped cross-section occurs. This method is described, for example, in US Pat. No. 2,523,251, and the result is shown in FIG. 2 of this patent. When folded blanks processed in this way are folded along the grooves, round (or in the case of several grooves) round or (in the case of two grooves) bevelled edges of the folded blanks are automatically formed.

The disadvantage, however, here is that, in view of the intrinsic stiffness and restoring efforts of the packaging material, bonding for the manufacture of packaging is not without problems. It is usually implemented in overlapping areas of the folding blank, which are formed by the side walls of the box. Due to the rounded or beveled edges, these overlapping areas are markedly reduced compared to a conventional box, for example, with a hinged lid, so that only a limited amount of adhesive can be applied. The consequence is a slowdown in automated production, since it is necessary to wait a longer time until a relatively small amount of adhesive material dries out properly.

This is especially noticeable when, for the manufacture of, for example, boxes with a hinged lid, cardboard or paper with a wide web is used. When making paper or paperboard, the product-forming material is laid on a fast-moving conveyor belt. This leads to the fact that the long fibers in the material are preferably oriented in the longitudinal direction. Depending on whether the folded blanks are then cut along or across the finished material web, the long fibers in the material of the folded blank are oriented transversely to the longitudinal axis of the folded blank (wide web) or along the longitudinal axis of the folded blank (narrow web). The orientation of the fibers across the longitudinal direction of the folding billet of a wide web results in good flexibility relative to the transverse axis, but poor flexibility relative to the longitudinal axis. Therefore, the regenerative forces for side bonding will be significantly greater than in the case of folding blanks from a narrow web, in which, due to the changed position of the long fibers in the material, exactly the opposite ratios will take place. On the other hand, for making boxes with a hinged lid, foldable blanks from a wide web are preferably used, since they significantly improve the lid stability (skewed during closing, eliminating the possibility of easy lid tear), packing rigidity due to increased stability in the transverse direction and a flat position packaging, i.e., the smallest possible deflection of the packaging, compared with the use of materials with a narrow web.

Due to the use of notches as opposed to corrugations, the reducing efforts are noticeably reduced, so that materials with a wide web can be used for making boxes without any problems, and reducing existing surfaces does not create problems when gluing the box.

For the manufacture of notches under the influence of the undercutter decreases the thickness of the material forming the package. To this end, the folding preform is laid on a smooth substrate and is processed by an undercutter, so that, along with compression, material can also be removed. Depending on the shape of the undercutter, a ν-shaped or u-shaped cross section, for example, occurs. Since the substrate does not have channels at opposite points of the undercutter, as in the manufacture of corrugations, but instead has a flat surface, there is a reduction in thickness, not deformation, without a decrease in thickness, as in corrugation.

The degree of thickness reduction depends on the material used and on the corresponding bend area. Notches of vertical bending areas are formed by reducing the thickness of paper or cardboard by 10 to 80%, preferably from 30 to 70% and particularly preferably from 4 0 to 60% or about 50%, and notches of horizontal bending areas - by reducing the thickness paper or cardboard 10-50%, preferably 20-40% or about 30%.

Notches are preferred for the foldable blanks according to the invention and for a second reason. They have the advantage that, since they are on the inside of the manufactured packaging, its outer side looks completely intact and untouched and provides the consumer with an improved appearance that is not achievable when using corrugations.

Due to the number of fold lines and their mutual distance from each other, the degree and type of rounding can be set. It is preferable to use on the fold area from 6 to 8, preferably 7 fold lines, which are about 1 mm apart from each other. When folded, it turns out a box with round edges; in this case, the rounding radius corresponds approximately to the radius of a regular cigarette sold on the market. It is also preferable to use two bend lines, which are at a distance of 6 to 8 mm, preferably 7 mm from each other, on the bend area. When folded, it turns out a box with beveled edges.

Due to the uniform appearance of the box, it is preferable that all of the fold areas have the same number of fold lines.

To pair the vertical and horizontal bend areas, it is preferable that the end of the circular arc segment and the end of the 8-shaped curve extend at a right angle to each other and lie parallel to the edges of the main face areas, as this way you can ensure a transition without any problems between different fold areas.

The preferred way, the segment of the arc of a circle and the 8-shaped curve are not connected to each other or are connected only at the corner point of the areas of the main faces. In principle, it is also possible that there is, at least partially, a connection between a circular arc segment and an 8-curve, then when folded to form a box this results in relative transitions and irregularities in the transition region between both different fold areas.

In addition, it is preferable that at least one bend area at both ends is bounded by either a segment of an arc of a circle, or an 8-shaped curve, and it is also preferable that in all bending areas that are at their both ends are substantially at right angles found with other areas of the fold, both ends of this area of the fold were bounded either by a segment of an arc of a circle, or by an 8-shaped curve. Finally, it is also preferable that all the bending areas lying parallel to each other are completed, respectively, with either a segment of an arc of a circle or an 8-shaped curve. In all three cases, this leads to a better appearance.

The manufacture of sheets with box blanks is carried out in a known manner. That is, the folding blanks are unwound from the cloths of the material of the folding blank,

Ί which are stored in rolls, and stuffed (sealed), preferably as folding blanks from a wide canvas. Usually, one working stage is implemented, at which the folded blanks are processed in the described way with the help of an undercutter or a device for corrugation and are simultaneously cut and / or cut, and, if necessary, pressed. By simply folding and gluing the folded blanks to the side surfaces, an automatically made cigarette box is then produced, which in the usual manner contains a pack of cigarettes packed in an inner wrapper. In a flip-lid box according to the invention, a portion of the rim is usually used, which in the open box protrudes slightly from the inside of the front wall of the box and has a cut-out that allows the cigarettes in the box to be caught.

The invention is illustrated below on the example of implementation. The drawings show:

FIG. 1 shows a folding blank according to the invention for producing a hinged-lid cigarette box; and FIG. 2 shows a detail детали in FIG. one.

You can see the first pad 20 of the main face, which in the manufactured box corresponds to the front wall of the part of the box with its adjacent platforms 22, 24 of the side faces. Between the left first side edge pad 22 and the first main face pad 20, as well as between the first main face pad 20 and the first right side pad 24, there are first and second vertical fold regions 90 and 91, which here are formed by 7 notches 100 and which in their the top end form a quarter of a circle.

The first platform 20 of the main face adjoins the top 30 bottom bottom, followed by the second platform 40 of the main face. Between the first main face area 20 and the bottom floor 30, there is a first horizontal fold area 80, and a second horizontal fold area 82 between the bottom floor 30 and the second main face area 40. These two horizontal areas 80 and 82 fold are also formed by 7 notches 100, which at their ends respectively illustrate the 8-shaped line. The second side of the main platform 40, which in the finished box corresponds to the back side of the box-like part, adjoins the second second side face pad 42 with the left second end overflow 46 of the side face and the second right side pad 44 with the right side on it. the second end inlet 48 side face. Between them are the third and fourth vertical areas 92 and 93 fold.

The third pad of the main face adjoins the third pad of the main face 50, to which the back wall of the cover corresponds to the finished box. Sites 40 and 50 of the main faces are separated by a 12-fold line so that the lid can be opened in the finished box. Between the third platform 50 of the main face and the left third pad 52 of the side face with the left third end overlap 56 of the side face on it, on the one hand, and the right third side face 54 of the side with the third third end overlap on it, on the other hand sides are the fifth vertical fold area 94 and the sixth vertical fold area 95. Vertical fold areas 92 and 93, as well as vertical fold areas 94 and 95, are separated from each other by cuts, which can extend to fold line 12 or even further.

At the upper side of the third pad 50 of the main face there is a cover pad 60, above which the fourth pad 10 of the lead face is located on its side. Between the third main face pad 50 and the lid pad 60, a third horizontal fold area 84 is located, and between the cover pad 60 and the third main ground pad 70 is the fourth horizontal fold area 86, which again, like all other fold areas, is formed by seven notches 100.

Around the fourth platform 70 of the main face, the left fourth pad 72 of the side face is grouped, the right fourth pad 7 4 side faces with the seventh and eighth vertical areas 96 and 97 of the fold between them, and the reinforcing pad 72. This reinforcing pad 72, due to its smaller sizes, has only four notches 100.

Vertical and horizontal bend areas are found in the corners of the main face areas, for example, the vertical bend areas 90 and 91 are with the horizontal bend area 80 in the upper corners 21 and 23 of the main face area. The vertical fold areas end in the embodiment of FIG. 1 on the arc of a quarter of a circle, which smoothly passes from one side to the upper edge of the corresponding adjacent side face area, and from the other side smoothly passes to the outer edge of the corresponding area of the main face. Horizontal bend areas end on 8-shaped curves, which smoothly transfer to the outer edges from one side of the corresponding adjacent base of the main face, and on the other side - to the adjacent bottom or top side of the platform.

Along with notches of 100 different bend areas, you can see other bend lines, for example, the bend line 12 between the second 40 and the third 50 plots of the main faces, the bend line 77 in the reinforcing pad 72 and the bend lines 55 and 45 relative to which the end can rotate overlaps of side edges.

For the manufacture of a cigarette box, you can first unscrew the platforms 42 and 44 of the lateral faces 90 ° upwards, and then the end slots 46 and 4 8 of the lateral faces located on them are also bent 90 ° inwards. Then the lower part of the folded billet 10 is bent over by the bottom 30 and the first platform 20 of the main face upwards by 90 °, so that the end overlaps 46 and 48 of the sides of the side edges come into contact with the platform 30 of the bottom and stick together. If the first pad 20 of the main face bends further (by 90 °), then the pad 22, 42 and 24, 44 of the side faces are superimposed on each other and can be glued together, resulting in the lower part of the box, i.e. the box part. Similarly, the upper part of the box, i.e., the lid part, is made, while the end inlets 56 and 58 of the side face pad are glued to the upper side pad 60. The reinforcement pad 72 is glued down to the fourth pad 70 of the main face, and thereafter, the pad 52, 72 and 54, 74 of the side faces are glued together. The notches 100 are therefore on the inside of the finished box and are not visible from the outside to the consumer.

The box with a hinged lid as described by folding has rounded longitudinal edges. In this case, the four horizontal main edges are also rounded. Due to the fact that the segment of the arc of a circle and an 8-shaped curve meet at the ends of the bend areas, a smooth transition between the bend areas is provided, and all 8 corners of the box are rounded in this way.

The conjugation of a circular arc segment and an 8-shaped curve is shown in more detail in FIG. 2 on an enlarged scale.

The vertical areas 91 and 93 of the fold end, respectively, on a segment of an arc of a circle from about 60 to 70 °, the horizontal areas 80 and 82 of the fold - on an 8-shaped curve. Segments of an arc of a circle and 8-shaped curves adjoin without connection to each other and meet at corner points 23 and 43.
