Description

Field of Invention

The invention relates to the packaging of tobacco products, a blank for packaging of tobacco products and to a method of folding the blank to form a packaging of tobacco products.

State of the art

A package of cigarettes is known, the so-called “box with shoulders”, which is a flat box that can be opened on top, containing a group of cigarettes, usually arranged in two layers, stacked on top of each other, and a lid hinged to the box using a sticker glued to the box and to the lid. The cuff located inside the box protrudes from the side walls of the box to the lid to guide and maintain the lid when it is in the open and closed positions, and to keep the lid in the closed position in contact with the box, which creates little resistance to the free movement of the lid.

Cigarette packages of the "box with a shoulder" type are currently manufactured using: a first blank which is glued and bent to form a box; a second blank, separate from the first, which is glued and bent to form a lid; a third blank, separate from the first and second, which is bent to form a cuff that is inserted inside and glued to the side walls of the box; and a sticker affixed around the box and lid to swivel the lid to the box.

The use of three separate blanks makes “box with shoulder” cigarette packaging difficult to manufacture due to the need to process three separate, independent packaging materials and three independent packaging devices, each of which is used to bend the respective blank. Also, due to the use of three independent packaging devices, the production site for the manufacture of “boxes with shoulders” turns out to be excessively cumbersome and, in general, ineffective, since it has to be completely stopped in case of problems (for example, wrinkling) on any of the packaging devices.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a package of tobacco products, a blank for packaging tobacco products, and a method of folding the blank to form a package of tobacco products designed to eliminate the above disadvantages in which the packaging of tobacco products is cheap and easy to manufacture. Tobacco products are preferably cigarettes.

According to the present invention, the following are created: packaging of tobacco products, a blank for packaging tobacco products and a method of folding the blank to form a packaging of tobacco products, as described in the attached claims.

Preferred Embodiments

Reference numeral 1 to FIGS. 1-4 indicates a whole pack of cigarettes, called a “shoulder box”.

The cigarette package 1 contains: a flat top-open box 2 containing a wrapped tobacco product group 3, i.e. a group of cigarettes (not shown) wrapped in a sheet of wrapping material - foil; and a lid 4 pivotally attached to the box 2 to <enable> the lid from the closed position (see FIG. 1), in which the open top end 5 of the box 2 is closed by the lid 4 to the open position (see FIGS. 2-4 ), in which the lid 4 is lifted from box 2 to allow access to a group of 3 cigarettes through the open upper end 5 of box 2.

Box 2 (see Figure 3) has a parallelepiped shape and contains: a lower wall 6, opposite the open upper edge 5; front wall 7 and rear wall 8, opposite and parallel to each other; and two parallel side walls 9, located between the walls 7 and 8. The cover 4 has a cup-shaped parallelepipedal shape and contains: an upper wall 10, opposite and parallel to the lower wall 6 of the box 2, when the lid 4 is closed; the front wall 11 and the rear wall 12, opposite and parallel to each other, which are parallel to and superimposed on the front and rear walls 7 and 8 of the box 2, when the lid 4 is closed; and two parallel side walls 13 that are parallel to and superimposed on the corresponding side walls 9 of the box 2 when the lid 4 is closed.

The lid 4 (see Figure 4) is pivotally attached to the box 2 by means of a hinge 14, which connects the rear wall 12 of the lid 4 with the external connecting wall 15, made in one piece with the rear wall 8 of the box 2. External (i.e. visible from the outside ) the connecting wall 15 (see Figure 5) is connected at the upper edge with the rear wall 12 of the cover 4 along the hinge 14 of the cover 4; and the inner connecting wall 16 (i.e., invisible, since it is located between the rear wall 8 of the box 2, on the one hand, and the rear wall 12 of the lid 4, and the outer connecting wall 15, on the other hand) is connected to the lower edge the edge of the outer connecting wall 15 along the transverse fold line 17a and connected at the upper edge to the upper edge of the back wall 8 of the box 2 along the transverse fold line 17b, and glued with adhesive 18 and 19 to the outer connecting wall 15 (but not to the rear wall 12 of the cover 4) , on the one hand, and to the back wall of 8 boxes and 2, on the other hand.

The upper wall 10 of the lid 4 (see FIG. 1) is larger (i.e., longer and wider) than the lower wall 6 of the box 2, so that when the lid 4 is closed, the front wall 11 of the lid 4 is superimposed on the front wall 7 of the box 2 and completely covers it, and the side walls 13 of the lid 4 are superimposed on the side walls 9 of the box 2 and completely cover them. It is important to note that the upper wall 10 of the lid 4 is only slightly larger than the lower wall 6 of the box 2, so that when the lid 4 is closed, the front wall 11 of the lid 4 fit tightly over the front wall 7 of the box 2, and the side walls 13 of the lid 4 fit tightly over the side the walls 9 of the box 2. Due to this feature, the box 2 thus guides and supports the lid when it is in the open and closed positions, and the contact between the box and the closed lid is maintained, slightly preventing the free movement of the lid 4. In other words, to timid 2 performs the function normally performed by the cuff in conventional containers of this type, thus allowing to exclude from the packaging sleeve structure 1.

Box 2 and lid 4 shown in FIGS. 1-5 are formed from a single blank 20 shown in FIG. 6 and containing several panels designated using the same position numbers corresponding to the position numbers of the walls of the box 2 and lid 4, with superscripts .

The workpiece 20 (see FIG. 6) has two internal longitudinal fold lines 21a and several transverse fold lines 17, which are limited (between two internal longitudinal fold lines 21a): a panel 11 'defining a front wall 11 of the cover 4; a panel 10 'forming the upper wall 10 of the cover 4; panel 12 '+ 15', forming the rear wall 12 of the cover 4 and the outer connecting wall 15, separated by a hinge 14 of the cover 4; panel 16 'forming the inner connecting wall 16; panel 8 'forming the rear wall 8 of the box 2; panel 6 'forming the bottom wall 6 of the box 2; and a panel 7 'forming the front wall 7 of the box 2.

The blank 20 comprises: two panels 13 ′ located on opposite sides of the panel 10 ′ connected to the panel 10 ′ along two internal longitudinal fold lines 21a and forming two side walls 13 of the cover 4; and two reinforcing panels 13 "located on opposite sides of the panels 13 ', connected to the panels 13' along two outer longitudinal fold lines 21b and superimposed on the respective panels 13 'and glued to them to reinforce the inside of the side walls 13 of the cover 4.

The blank 20 comprises a reinforcing valve 11 ″ connected to the panel 11 ′ along the transverse fold line 17, superimposed on the panel 11 ′ and glued thereto for reinforcement from the inside of the front wall 11 of the lid 4. The blank 20 preferably comprises a through hole 22 ′ made symmetrically between the panel 11 'and the reinforcing valve 11 ", restricting the window 22 in the front wall 11 of the cover 4 (see Figure 1), using which, capture and open the cover 4. As an alternative to the window 22 in the front wall 11 of the cover 4 can be performed two symmetrical x windows in the side walls 13 of the lid, similar to the window 22 in the front wall 11 of lid 4, and may be limited to corresponding through hole formed symmetrically between panels 13 'and reinforcing panels 13 ".

The panel 11 'comprises two tabs 23 located on opposite sides of the panel 11', connected to the panel 11 'along two internal longitudinal fold lines 2la, which are glued to the panels 13'. The panel 12 '+ 15' contains two tabs 24 located on opposite sides of the panel 12 '+ 15', connected to the panel 12 '+ 15' along two internal longitudinal lines of the fold 21a and glued to the panel 13 '. The outer edges of the two reinforcing panels 13 ″ are preferably made in a shape that negatively reproduces the shape of the tongues 23 and 24 so as not to overlap the tongues 23 and 24 in any way, but at the same time substantially completely cover the inner surface of the panels 13 ′ ( as clearly shown in FIG. 11).

In one embodiment, each tongue 24 is connected to the rear wall 12 of the lid 4 along the indissoluble part of the inner longitudinal line of the bend 21a and connected to the outer connecting wall 15 along the torn part of the inner longitudinal line of the bend 21a so that each side wall 13 of the lid 4 is initially connected with the back wall 8 of the box 2 along the tear line torn when the lid 4 is opened for the first time. This feature is particularly suitable in the manufacture of a cigarette package 1 by holding the lid 4 in the closed position the transfer of the package 1 with the packaging machine where it is manufactured on a machine for packaging in plastic, for the imposition of a transparent overwrap packaging 1.

The blank 20 has two panels 9 ', located on opposite sides of the panel 6' and connected to the panel 6 'along two internal longitudinal fold lines 21a, and forming two side walls 9 of the box 2. Each panel 9' contains a tongue 25 connected to the panel 9 'along the transverse line of the fold 17, and it is glued to the panel 8'; and the tongue 26, connected to the panel 9 'along the transverse line of the fold 17 from the opposite edge from the tongue 25, is glued to the panel 7'.

One possible sizing configuration of the preform 20 is shown in FIGS. 7 and 8, which show the front surface areas of the preform 20 that are coated with adhesive 18 (see FIG. 7) and the rear areas of the surface of the preform 20 that have adhesive 19 applied (see Fig. 8). The sizing configuration of the preform 20 shown in FIGS. 7 and 8 can, of course, be varied, for example, by increasing the rear areas of the surface of the preform 20 to which the adhesive 19 is applied, and, accordingly, reducing the front areas of the surface of the preform 20 that are applied to the adhesive eighteen.

The following is a description of preferred (but not only) methods of bending the preform 20 to form a package of 1 cigarette (see Fig.9-17).

The preform 20 (see FIG. 9) is first bent one (i.e., before the group of 3 cigarettes is placed on the panel 6 ') by folding the panel 12' + 15 '180 ° around the transverse fold line 17a relative to and on the panel 16' and by folding the panel 16 '180 ° about the transverse fold line 17b relative to the panel 8' and on it. Panels 12 '+ 15' and 16 'are preferably folded 180 ° at the same time relative to panels 16' and 8 'to form a Z-shaped bend and, of course, after applying glue 18 and 19 on the panels 15', 16 'and 8' as shown, for example, in FIGS. 7 and 8.

The preform 20 is preferably folded one (i.e., prior to placing the cigarette group 3 on the panel 6 ′) by folding the reinforcement valve 11 ″ 180 ° around the transverse line of the fold 17 relative to and on the panel 11 ′ and by folding each reinforcement panel 13 ″ onto 180 ° around the corresponding outer longitudinal line of the fold 21b relative to and on the corresponding panel 13 ' . Of course, prior to bending the reinforcing valve 11 "and the reinforcing panels 13" through 180 ° with respect to the panels 11 'and 13', an adhesive 18 is applied to the reinforcing valve 11 ", the reinforcing panel 13" and the panels 11 'and 13', as shown, for example, in Fig.7.

After bending the preform 20 according to the above description, it looks like that shown in Figures 10 and 11. At this time, a group of 3 cigarettes are placed on the preform 20, specifically on the panel 6 'of the preform 20; and the preform 20 is folded around a group of 3 cigarettes to form a box 2 and a lid 4.

After the group 3 of cigarettes is placed on the panel 6 '(i.e., after the panels 12' + 15 'and 16', the reinforcement valve 11 "and the reinforcement panels 13" are bent) (see Fig. 12), each panel 9 ', forming the side wall 9 of the box 2, is bent 90 ° around the inner longitudinal line of the fold 21a relative to the panel 6' and a group of 3 cigarettes. Then, each tongue 25 (see FIG. 13) is bent 90 ° around the transverse fold line 17 with respect to the corresponding panel 9 'and a group of 3 cigarettes; and each tongue is 26 bend 90 ° around the transverse line of the fold 17 relative to the corresponding panel 9 'and a group of cigarettes.

After two panels 9 ', two tabs 25 and two tabs 26 are bent 90 °, see panel 12' + 15 ', panel 16' and panel 8 'are bent together 90 ° around a transverse line fold 17 relative to the panel 6 'and to group 3 of cigarettes; after that, the panel 10 'is bent 90 ° (see Fig. 15) around the transverse line of the fold 17 relative to the panel 12' + 15 'and a group of 3 cigarettes.

At this time (see Fig. 16), the panel 11 '(together with the reinforcing valve 11 "superimposed on the panel 11' and glued thereto) is bent around the transverse fold line 17 relative to the panel 10 'and on the cigarette group 3 (see 17). After the panel 11 ', the panel 10', the panel 12 '+ 15', the panel 16 'and the panel 8' are bent 90 °, each tongue 23 is bent 90 ° (see Fig. 17) around the inner longitudinal bend line 21a relative to the panel 11 'and to the cigarette group 3; and each tongue 24 is bent 90 ° around the inner longitudinal bend line 21a relative to the panel 12' + 15 'and to the cigarette group 3.

Finally, each panel 13 '(together with a corresponding reinforcing panel 13 "superimposed on the panel 13' and glued thereto) is folded 90 ° around the inner longitudinal fold line 21a relative to the panel 10 'and on the cigarette group 3 to complete the packaging process 1 cigarette.

In a preferred embodiment of the invention (of course, not limiting the scope of the invention), the panels 12 ′ + 15 ′ and 16 ′, the reinforcing valve 11 ″ and the reinforcing panels 13 ″, which are bent to accommodate a group of 3 cigarettes on the workpiece 20, are bent on a packaging machine ( for example, in the factory where the billets 20 are made, or in the intended folding machine located upstream of the packaging machine), and the subsequent bending of the billet 20 around group 3 of cigarettes is performed on a packaging machine (for example, on a company model “X6” company Gd Societa per Azioni).

In an alternative embodiment illustrated in FIG. 18, a window 27 is provided in the rear wall 12 and in the inner connecting wall 16 of the box for easy removal of cigarettes from cigarette group 3, i.e. to also provide consumer access to a portion of the rear wall, as opposed to access only to the upper wall bounding the cigarette group 3. In Fig.19 shows the workpiece 20 for forming a package of 1 cigarette shown in Fig.18. As shown in the drawing, the through hole 27 'defined by the window 27 is formed through the panels 8' and 16 'and is mirror symmetrical on both sides of the transverse fold line 17b.

In one embodiment, a holding device may be provided for holding the closed lid 4 in contact with the box 2 with a predetermined force that must be overcome to open the lid 4. For example, the holding device may comprise an elastically deformable device protruding from the front wall 11 of the lid 4, which flexes elastically when mated with a corresponding socket made in the front wall 7 of the box 2 (or may contain two devices protruding from the side walls 13 of the cover 4, which are mating tsya with corresponding slots made in the lateral walls 9 of the box 2).

In one embodiment, the cigarette package 1 may comprise an outer sticker adhered to the outer sides of the box 2 and lid 4 to cover the outer surfaces of the box 2 and lid 4, essentially to give an aesthetically pleasing appearance, but which may also have design features in the formation of an additional hinge between the box 2 and the lid 4, but located outside and used in parallel with the hinge 14.

In another embodiment (not shown) reinforcing valve 11 "and / or reinforcing panels 13" are excluded. Reinforcing valve 11 "and reinforcing panels 13" are used to hide the cardboard edges and to strengthen the front wall 11 and side walls 13 of the cover 4, respectively. Although these functions are useful, they are not required to pack 1 cigarettes, therefore, reinforcing valve 11 "and / or reinforcing panels 13" can be omitted to save packaging material and simplify the process of bending the workpiece 20.

In the embodiments shown in the drawings, all edges of the box 2 and the lid 4 are rectangular. In embodiments (not shown), at least some of the longitudinal and / or transverse edges are beveled or rounded.

The described packaging of 1 cigarette has several advantages.

In particular, it is cheap and can be manufactured very quickly because the box 2 and the lid 4 are formed from a single blank 20, which, thanks to its construction, can be easily manufactured using a standard packaging machine.

In addition, in the described cigarette package 1, the connection between the box 2 and the lid 4 is very strong and accurate due to the fact that it is mainly determined by the hinge 14 made directly in the workpiece 20 (as opposed to just the outer sticker, as is the case in conventional packages such as "boxes with shoulders"). The exact location of the hinge between the box 2 and the lid 4 is especially important, since even with the slightest inaccuracy in manufacturing, the lid 4 is difficult to properly close the box 2 (i.e., the lid 4 excessively rubs against the box 2, which thus complicates it opening and closing).

Due to the triple thickness of the package 1 of cigarettes in the hinge region 14 (due to the overlapping of the rear wall 12 of the cover 4, the outer connecting wall 15, the inner connecting wall 16 and the rear wall 8 of the box 2, as shown clearly in FIG. 5), the hinge area is obtained especially strong and rigid, and thus ensures accurate and accurate rotation of the cover 4 relative to the box 2, i.e. the hinge does not wear out during the period of use.

Finally, the cigarette package 1 described does not necessarily require the use of an external sticker glued around the box 2 and the lid 4. Since the use of the external sticker is an expensive process and its accurate gluing is a difficult operation, eliminating the external sticker can significantly reduce the manufacturing cost. And even if the outer sticker adhered around the box 2 and the lid 4 is selected, no matter what, it can be small, and thus, material consumption can be reduced and corresponding folding operations can be simplified. The reason for this is that when connecting the box 2 and the lid 4 using a hinge 14 made directly in the workpiece 20, the outer sticker has a purely aesthetic function, not a constructive one.

Owing to several advantages of the design of the package 1, cigarettes can also be used in the manufacture of packages for other tobacco products (for example, cigars) or for the manufacture of a box substantially similar to the described package 1 of cigarettes, but containing a group of cigarette packs instead of a group of 3 cigarettes.
