Description

The present invention relates to a pack for smoking articles, in particular cigarettes, and a workpiece for making such a pack.

Hard packs for cigarettes are widely known, i.e. packs obtained by folding blanks from cardboard, especially appreciated by users, since they prevent damage to cigarettes even when they are hit or stored in a consumer’s pocket or bag.

Recently, there has been a tendency to modernize traditional hard packs, caused by the desire to persuade users to choose a pack that has a certain appearance compared to other packs of a more traditional look.

For this purpose, a bundle was developed comprising a containing body having a substantially parallelepiped shape and a base from which two large side surfaces protruding opposite each other. The enclosing body also contains two smaller side surfaces, each of which is located between the large side surfaces. The enclosing body includes an upper opening through which cigarettes can be removed.

The outer shell is located partially around the enclosing housing. The outer shell contains a bottom wall that rotates on the base of the enclosing body about the axis of rotation. The rotation axis, having the form of a straight line, is formed by a softening line made on the basis of the pack.

The outer shell also comprises two large side walls protruding from the lower wall, the smaller side wall being located between the large side walls. In addition, the outer shell contains an upper wall connected to the corresponding upper edge zones of the smaller side wall and large side walls. Between the corresponding free edges of the large side walls and the upper wall, a side hole is defined to provide access to the enclosing body.

The outer shell can rotate around a pivot axis formed on the base of the pack, thereby moving between a closed position in which the outer shell closes the upper opening of the enclosing body and an open position in which the user can remove the cigarette.

Packages of this type are described, for example, in European patent applications EP 1923329 and EP 1829799 and in international patent application WO 2006/021581.

The disadvantage of the described packs is that the rotation axis is easily damaged and affects the appearance of the pack. Indeed, due to the multiple folding required to open and close the pack, the printed outer layer covering the pack may crack along the pivot axis.

In addition, the free edges of the large side walls of the outer shell defining the lateral hole tend to take a curved configuration and fold outside the pack. Thus, an unaesthetic empty space is defined between the large side walls of the outer shell and the large side surfaces of the enclosing body.

The objective of the present invention is to improve the package for smoking articles, in particular for cigarettes, and the workpiece that can be used to obtain such a package.

Another objective of the present invention is to provide a pack for smoking articles containing an outer shell that rotates on a housing located inside the outer shell, which reduces the likelihood of damage to the connection between the outer shell and the housing.

Another objective of the present invention is the creation of a pack for smoking articles containing an outer shell and a containing body located inside the outer shell, in which the free edges of the outer shell are not too distant from the containing body.

Another objective of the present invention is to provide a pack for smoking articles having an original appearance compared to a traditional rigid pack.

In accordance with a first aspect of the present invention, there is provided a pack for smoking articles, comprising: a housing for housing smoking articles and an outer shell, the containing housing being located inside the outer shell; a connecting device for connecting the enclosing body to the outer shell on the wall, characterized in that the connecting device contains a pivoting element passing through the layer of the specified wall, allowing rotation of the outer shell and the enclosing body relative to each other.

In accordance with a second aspect of the present invention, there is provided a blank for producing a shell of a pack for smoking articles, comprising a main panel for producing a longitudinal wall of the shell and an auxiliary panel for producing a transverse wall of the shell, characterized in that a tear line is provided on the main panel for receiving a rotary element a connecting device, and the line of rupture is closed in the form of a loop.

The first aspect of the present invention allows to obtain a pack for smoking products, in which the enclosing body and the outer shell can be repeatedly rotated relative to each other without damaging the possible printed coating of the pack. Indeed, the rotary element passing through the layer of the bundle wall allows eliminating softening lines that act as rotation axes and are easily cracked from repeated bending.

The preform in accordance with the second aspect of the present invention makes it particularly easy to manufacture the bundle in accordance with the first aspect of the present invention on a slightly modified conventional packaging machine.

The enclosing body and the outer shell also allow the pack to be upgraded compared to a traditional rigid pack and to produce a very wide accessible surface on which messages for the consumer can be printed.

In accordance with one embodiment of the present invention, the outer shell comprises a pair of large side walls facing each other and located along the axis of the packet.

The enclosing body may comprise a pair of large sides and a pair of smaller sides, each of the smaller sides being located between two large sides.

A connecting device may connect the large side wall of the outer shell to the corresponding large side of the enclosing body.

Another connecting device may be provided for connecting the other large side wall of the outer shell to the corresponding other large side side of the enclosing body.

This prevents deformation of the large side walls of the outer shell and their distance from the large sides of the enclosing body, leading to the formation of an undesirable and unaesthetic empty space.

The accompanying drawings will allow a better understanding of the present invention, in which, as non-limiting examples, some embodiments of the invention are presented.

On Fig presents the outer side of the workpiece of Fig.11.

Figure 1-4 presents a pack 1 of a rigid type, which can accommodate smoking products, in particular cigarettes. The pack 1 has a Z axis, which is shown in Fig.3. Cigarettes or other smoking articles contained in packet 1 are oriented substantially parallel to the Z axis.

The pack 1 contains an outer shell 2, which can be obtained by folding a workpiece made, for example, of cardboard. The outer shell 2 comprises a first large side wall 3 and a second large side wall 4, which are located opposite each other. The first large side wall 3 and the second large side wall 4 are oriented along the Z axis.

The outer shell 2 also contains a first smaller side wall 5 and a second smaller side wall 6, which are located opposite each other. The first smaller side wall 5 is located between the first and second large side walls (3, 4), the same applies to the second smaller side wall 6. The first smaller side wall 5 and the second smaller side wall 6 are also oriented along the Z axis.

The first and second large side walls 3, 4 and the first and second smaller side walls 5, 6 may be flat. In accordance with the presented example, these walls are connected to each other by rounded edge zones 7, which are oriented along (parallel to) the Z axis. Thus, packet 1 has the form of a packet with rounded edges. According to an embodiment of the invention not shown in the figures, the edge zones connecting two adjacent side walls can be chamfered so as to form an octagonal bundle 1. Two adjacent side walls can also be connected at right angles, as a result of which the resulting bundle 1 will have the shape of a parallelepiped, like a traditional rigid bundle. In general, the edge zones connecting the two adjacent side walls may have any desired shape.

The outer shell 2 also contains a lower wall 8 and an upper wall 9, which are located opposite each other. The lower wall 8 and the upper wall 9 may be substantially flat. The lower wall 8 and the upper wall 9 can extend transversely to the Z axis, in particular perpendicular to this axis.

The first large side wall 3 and the second large side wall 4 are adjacent to the lower wall 8 and the upper wall 9. The length of the first smaller side wall 5 and the second smaller side wall 6 is less than the length of the first large side wall 3 and the second large side wall 4. In particular , the first smaller side wall 5 is adjacent to the lower wall 8, but is located at a distance from the upper wall 9. Between the first large side wall 3, the second large side wall 4, the first smaller side wall 5 and the upper wall 9, a first side opening is provided s 10, the purpose of which will be described in detail below.

On the other hand, the second smaller side wall 6 borders on the upper wall 9, but is located at a distance from the lower wall 8. Thus, between the first large side wall 3, the second large side wall 4, the second smaller side wall 6 and the lower wall 8 is provided the second side hole 11. The second side hole 11 is located opposite the first side hole 10 diagonally. Essentially, the second side hole 11 is located at the bottom of the pack 1, and the first side hole 10 is located at the top of the pack 1.

As shown in FIG. 2, the outer shell 2 also has two openings 12 in the form of through slots provided between the second smaller side wall 6 and, accordingly, the first large side wall 3, and the second large side wall 4. Thus, the holes 12 are located above the second side hole 11. The first large side wall 3 and the second large side wall 4 may contain print areas, drawings or messages, in particular a frame 13, inside which contains messages intended for the user.

The pack 1 also contains a housing 14 located inside the outer shell 2. The housing 14 can accommodate smoking articles, for example, cigarettes, wrapped in a metal sheet or foil, forming an inner wrapper 15, which can be seen in Fig.6.

The enclosing body 14 may be cup-shaped.

As shown in FIGS. 3 and 4, the enclosing body 14 comprises a lower side 16, which may be flat and transverse, in particular perpendicular to the smoking articles. The enclosing body 14 also includes a first large side 17 and a second large side 18. The first large side 17 and the second large side 18 are located opposite each other. These sides are oriented in the same direction as the smoking articles enclosed in the inner wrapper 15.

The enclosing body 14 also has a first smaller side 19 and a second smaller side 20. A first smaller side 19 and a second smaller side 20 are located between the first large side 17 and the second large side 18. The first smaller side 19 and the second smaller side 20 is located opposite each other. The first smaller side 19 and the second smaller side 20 are oriented in the same direction as the smoking articles.

The first smaller lateral side 19 and the second smaller lateral side 20 are connected to the first large lateral side 17 and the second large lateral side 18 by respective edge regions 21. In accordance with the presented example, the edge regions 21 have a rounded edge. However, the edge regions 21 may also have other shapes, in particular corresponding to the shapes of the edge zones 7 of the outer shell 2.

The enclosing body 14 has an upper opening 22 through which the user can remove smoking articles.

The pack 1 also contains connecting means for connecting the outer shell 2 with the enclosing body 14 with the possibility of rotation. In particular, the connecting means may include a connecting device 23 connecting the first large side wall 3 of the outer shell 2 with the first large side 17 of the housing body 14. The connecting means may include another connecting device 24, shown in figure 4, for connecting the second large side the walls 4 of the outer shell 2 with the second large side 18 of the enclosing body 14.

As shown in FIG. 4, the connecting device 23 and the other connecting device 24 may be facing each other, so as to have a common rotation axis X. Thus, the enclosing body 14 and the outer shell 2 can rotate relative to each other around a common axis X of rotation, moving from the closed position shown in Fig.1-4, to the open position shown in Fig.6.

In the closed position, the enclosing body 14 is located inside the outer shell 2. In this position, the Z axis along which the outer shell 2 extends substantially coincides with the direction of the smoking articles inside the enclosing body 14. The upper opening 22 of the enclosing body 14 is closed by the upper wall 9 of the outer shell 2, which prevents smoking articles from falling out of the packet 1.

In the open position, the housing 14 is rotated with respect to the outer shell 2. In this position, the upper part of the housing 14 extends beyond the outer shell 2 through the first side hole 10. This provides access to the upper hole 22 for extracting smoking articles contained in the housing 14. In addition, in the open position, the lower part of the enclosing body 14 projects beyond the outer shell 2 through the second side hole 11.

To move from a closed state to an open one and vice versa, the enclosing body 14 and the outer shell 2 are rotated relative to each other by a predetermined angle, for example, approximately 45 °.

Figure 5 shows on an enlarged scale a connecting device 23. The connecting device 23 comprises a pivoting member 25 extending through the thickness of the first large side wall 3. The pivoting member 25 may be in the form of a circular disk made from the material of the outer shell 2. The cut line defined by the slots 26, separates the pivoting member 25 from the surrounding areas of the first large side wall 3.

The pivoting member 25 has a first surface 27 attached to the first large side 17 of the enclosing body 14, for example, by means of an adhesive 28.

The locking element 29 is attached to the pivoting element 25 to prevent the pivoting element 25 from separating from the first large side wall 3. The size of the fixing element 29, measured transversely to the axis X of rotation, is larger than the transverse dimension of the pivoting element 25. Thus, the fixing element 29 has a surface 30 which is suitable for adhering to the first large side wall 3. The adjoining surface 30 prevents the pivoting member 25 from separating from the first large side wall 3 even if element of 25 is pushed inwards the packet 1.

In accordance with the presented example, the locking element 29 has the shape of a circular plate, the diameter of which is larger than the diameter of the rotary element 25. However, the locking element 29 may have any desired shape, not necessarily round.

The locking element 29 is attached to the rotary element 25 by means of an adhesive distributed, for example, in the form of a plurality of adhesive points 31. The adhesive points 31 are applied between the fixing element 29 and the second surface 32 of the rotary element 25, the second surface 32 being located opposite the first surface 27.

The locking element 29 can be made, for example, of the same material as the enclosing body 14 and / or the outer shell 2, for example, of cardboard.

The thickness of the pivoting member 25, measured along the pivot axis X, is substantially equal to the thickness of the large side wall 3 of the outer shell 2.

In particular, as will be described in detail below, the pivot element 25 can be obtained by cutting the material from which the first large side wall 3 is formed along the cut line defined by the slots 26. The pivot element 25 can be connected to the surrounding areas of the first large side wall 3 by connecting parts , which can be, for example, torn by the user the first time you open the package 1.

Through the openings 12, the user can press on the enclosing casing 14 so that the enclosing casing 14 exits the outer shell 2 through the first side opening 10 and the second side opening 11. Thus, it is possible to open the stack 1. To close the stack 1, it is enough for the user to act on the upper part of the enclosing body 14 extending from the first side opening 10 and / or the lower part of the enclosing body 14 extending from the second side opening 11, so as to rotate the enclosing body 14 from the open position to the closed.

The pivoting member 25 allows the pivoting connection to be established between the outer shell 2 and the housing 14, in particular between the first large side wall 3 and the first large side 17. The pivoting member 25 acts as an axis passing through the thickness of the first large side wall 3. Thus , rotary joints obtained using a softening line made on the outer surface of the bundle, which easily damages the printed outer surface of the bundle, are not required. On the contrary, the rotary element 25 allows you to repeatedly open and close the pack 1 without the risk of damage to the visible surface of the pack 1 and possible inscriptions or drawings printed on it.

The pivoting member 25 and the locking member 29 define a connection between the first large side wall 3 and the first large side 17 in the respective central zones of this wall and this side. This allows you to maintain contact of the first large side wall 3 with the first large side 17 and prevents excessive deformation of the first large side wall 3 from bending outward. Thus, the formation of undesirable free space between the free edge of the first large side wall 3, partially restricting the first side opening 10, and the enclosing body 14 is eliminated. This positive effect becomes even more noticeable with the other connecting device 24 connecting the second large side wall 4 and the second large side 18.

If there is another connecting device 24, its design and operation are similar to the design and operation of the connecting device 23.

One or more printed characters arranged in such a manner as to cooperate with one or more other printed characters printed on the outer surface of the first large side wall 3 to print a message to the user may be printed on the fixing member 29. These may be different messages, depending on whether the pack 1 is in the open or closed position. For example, the first position indicating means 33 may be printed on the locking element 29, for example, containing a double arrow. On the outer surface of the first large side wall 3, second position indicating means 34 may be printed, containing, for example, two letters “C” in diametrically opposite positions and two letters “O” in diametrically opposite positions and rotated at an angle of approximately 45 ° with respect to the pair of letters “C”. When the pack 1 is in the closed position, the double arrow printed on the locking element 29 is in the vertical position, so that each end of the arrow is directed to the letter “C” (closed) printed on the first large side wall 3. If the enclosing body 14 rotate so as to give it an open position, the locking element 29 rotates together with the enclosing body 14, and the double arrow tilts at an angle of approximately 45 °. Thus, the double arrow points toward the two letters “O” (open) printed on the first large side wall 3.

It is clear that instead of the double arrow and the pairs of letters “O” and “C”, any other printed sign printed on the fixing element 29 and the first large side wall 3 can be used.

This allows you to get a pack 1 having a characteristic appearance, easily distinguishable from the appearance of traditional packs available on the market, which is an element attractive to the user.

As shown in FIGS. 3 and 4, a gap G1 can be provided in the closed position between the inner wrapper 15 and the upper wall 9 of the outer shell 2. In the same position, a different gap G2 can be provided between the enclosing body 14 and the lower wall 8 of the outer shell 2. The gap G1 and the other gap G2 may be the same or different from each other. Due to the gap G1 and the other gap G2, when the enclosing body 14 is moved from the closed position to the open or vice versa, the inner wrapper 15 and the enclosing body 14 do not hit the lower wall 8 or the upper wall 9 of the outer shell 2.

In order to avoid interaction between the inner wrapper 15 and the upper wall 9 of the outer shell 2, an adhesive can also be used to attach the upper valve 35 of the inner wrapper 15 to the underlying valve 36, as shown in FIG. 6. This prevents the upper valve 35 from separating from the underlying valve 36 and touching the upper wall 9 when the enclosing body 14 is rotated. A similar solution can also be applied at the lower end of the inner wrap 15.

The top valve 35 is opened by the user upon first opening the packet 1 to gain access to smoking articles.

So that the gap G1 does not lead to the creation of an unaesthetic empty space, visible when the pack 1 is closed, the enclosing body 14 has an upper side end 37 protruding to the upper wall 9 relative to the inner wrapper 15. The upper side end 37 is located on the side of the enclosing body 14, in a closed the position facing the first side hole 10. The size of the upper side end 37 is determined so that it is in contact or almost in contact with the upper wall 9 with the closed position of the pack 1, so that the gap G1 was hidden in this position. The other upper lateral end 38 of the housing 14, opposite the upper lateral end 37 and also facing the upper wall 9, on the other hand, is located essentially flush with the inner wrap 15 to avoid collision with the upper wall 9 during rotation.

The first smaller lateral side 19, as well as the adjacent edge regions 21, protrude toward the upper wall 9 more than the second smaller lateral side 20, so that the upper lateral end 37 is at a different level relative to the other upper lateral end 38.

In the same way, so that the other gap G2 is hidden when the pack 1 is closed, the enclosing body 14 has a lower side end 39 protruding from the inner wrapper 15 to the lower wall 8. The lower side end 39 is located on the side of the enclosing body 14, in the closed facing the second side hole 11. In other words, the lower side end 39 is located diagonally with respect to the upper side end 37. The size of the lower side end 39 is determined so that it is substantially in contact with the bottom wall 8 with the closed position of the pack 1.

The other lower side end 40 of the housing 14 opposite the lower side end 39, on the other hand, is substantially flush with the inner wrap 15 to avoid collision with the bottom wall 8 when the housing 14 is rotated between the open and closed positions.

The lower lateral end 39 is bounded by a second smaller lateral side 20, which, like the adjacent edge regions 21, protrudes toward the lower wall 8 more than the first smaller lateral side 19.

In accordance with one embodiment of the present invention, not shown, the connecting device 23 and / or other connecting device 24 may comprise a pivot element that extends not through the thickness of the large side wall of the outer shell 2, but through the large side of the enclosing body 14 In this case, the locking element is located inside the enclosing body 14. In addition, the pivoting element is attached to the corresponding large side wall of the outer shell 2.

In general, the large side wall (first large side wall 3 or the second large side wall 4) of the outer shell 2 and the corresponding large side of the enclosing body 14 constitute the wall of the stack 1. This wall has a two-layer structure, and one layer is a large side wall of the outer shell 2, and the other side is the large side of the enclosing body 14. The pivoting member 25 may extend through either of these two layers. The pivoting member 25 is attached to that of said two layers through which it does not pass. The locking member 29 is located on the side of the pivoting member 25 opposite to the layer to which the pivoting member 25 is attached.

Figure 7 presents the workpiece 41, made, for example, of cardboard, which can be used to receive the enclosing body 14 of the pack 1.

The blank 41 comprises a base portion 42 for receiving the lower side 16 of the housing body 14. The base portion 42 has a substantially rectangular shape corresponding to the cross section of the housing body 14. The portion 42 has four rounded corner zones 43. The base portion 42 is connected by two folds 44 with the first large part 45 and the second large part 46, intended to receive the large lateral sides 17, 18 of the enclosing body 14. On the two sides of the first large part 45 are located the first smaller part 47 and the other first the smallest part 48. On the two sides of the second major part 46 are the second smaller part 49 and the other second smaller part 50. When folding the workpiece 41, the first smaller part 47 and the second smaller part 49, as well as the other first smaller part 48 and the other second smaller part 50 impose on each other. In this way, a first smaller side 19 and a second smaller side 20 of the housing 14 are obtained.

Parallel fold groups 51 are located between the first large part 45 and the first smaller part 47, between the first large part 45 and the other first smaller part 48, between the second large part 46 and the second smaller part 49, between the second large part 46 and the other second smaller part 50 Groups of 51 folds are intended to produce rounded edge regions 21 of the housing body 14.

In addition, a plate 52 is connected to another first smaller portion 48, which, after folding, is located between the inner wrapper 15 and the base portion 42.

The shaded areas on the workpiece 41 indicate the attachment areas 53 onto which adhesive can be applied. The attachment zones 53 provided on the second smaller portion 49 and on the other second smaller portion 50 allow these parts to be attached to the first smaller portion 47 and the other first smaller portion 48, respectively. The attachment zone 53, provided on the plate 52, allows the inner wrapper 15 to be attached to the enclosing body 14.

The first major part 45 and the second major part 46 are bounded on the side opposite the base part 42 by respective U-shaped profiles 54, which gives the first large side 17 and the second large side 18 of the housing 14 a characteristic U-shape of the internal frames used in traditional bundles.

The first smaller portion 47 and the second smaller portion 49 are bounded by respective transverse edges 55, the distance to which from the corresponding fold 44 is less than the distance from this fold to other transverse edges 56 defining another first smaller portion 48 and another second smaller portion 50. As a result, In the housing 14, the upper lateral end 37 protrudes toward the upper wall 9 more than the other upper lateral end 38.

The first smaller part 47 and the second smaller part 49 are also bounded next to the base part 42 by respective edge lines 57. The edge lines 57 are at a different level of the folds relative to the folds 44, as a result of which in the enclosing body 14 the lower side end 39 projects from the lower surface 16.

The preform 41 may be folded, for example, around the inner wrapper 15 to form a housing 14.

On Fig presents the inner side of the workpiece 59, made, for example, of cardboard, which can be folded to obtain the outer shell 2 of the pack 1.

The blank 59 comprises a first large panel, or a first main panel 60 connected to the first smaller panel, or the first auxiliary panel 61. The first auxiliary panel 61 is designed to receive the upper wall 9 of the outer shell 2.

The second main panel 62 is connected to the first auxiliary panel 61 on the side opposite to the connection side of the first auxiliary panel 61 with the first main panel 60. The first main panel 60 and the second main panel 62 are designed to receive respectively the first large side wall 3 and the second large side wall 4 outer shell 2.

The first main panel 60, the first auxiliary panel 61 and the second main panel 62 are arranged sequentially along the longitudinal axis Y. As a result, the design of the preform 59 is not too different from the design of the preform to form a conventional cigarette pack.

The second auxiliary panel 63 is connected to the first main panel 60 on the side opposite the connection side to the first auxiliary panel 61. In the same way, the other second auxiliary panel 64 is connected to the second main panel 62 on the side opposite to the connection side to the first auxiliary panel 61. The second the auxiliary panel 63 and the other second auxiliary panel 64 are arranged to overlap to obtain a lower wall 8 of the outer shell 2.

The first sub-panel 61, the second sub-panel 63 and the other second sub-panel 64 have a substantially rectangular shape corresponding to the cross section of the outer shell 2, with rounded corners 65. The corners 65 can also be straightened or sharp, or have a different shape as desired the cross section of the outer shell 2.

Transverse folds 66 are located between the second auxiliary panel 63 and the first main panel 60, between the first main panel 60 and the first auxiliary panel 61, between the first auxiliary panel 61 and the second main panel 62 and between the second main panel 62 and the other second auxiliary panel 64. Transverse folds 66 are laterally, in particular perpendicular to the longitudinal axis Y.

The first side panel 67 is connected to the edge zone of the first main panel 60 parallel to the longitudinal axis Y. The length of the first side panel 67, measured parallel to the longitudinal axis Y, is less than the length of the first main panel 60. The edge zone of the first main panel 60 to which the first the side panel 67 is located next to the second auxiliary panel 63 and at a distance from the first auxiliary panel 61.

The other first side panel 68 is connected to the edge zone of the second main panel 62, having approximately the same length measured along the longitudinal axis Y as the first side panel 67. The edge zone of the second main panel 62, to which the other first side panel 68 is connected, extends parallel to the longitudinal axis Y, is adjacent to the other second auxiliary panel 64 and is located at a distance from the first auxiliary panel 61.

The other first side panel 68 is designed to be folded onto the first side panel 67, so as to define a first smaller side wall 5 of the outer shell 2. The first side panel 67 and the other first side panel 68, the length of which is less than the length of the respective main panels located at a distance from the first auxiliary panel 61, you can determine the first side hole 10 in the outer shell 2.

The first plate 69 is also connected to another first side panel 68, wherein the first plate 69 is foldable at an angle of 90 ° so as to be in position between the bottom wall 8 and the housing body 14. The first plate 69 allows you to hide an unaesthetic empty space in the finished pack 1 between the bottom wall 8 and the first smaller side wall 5 of the outer shell 2.

In a position diametrically opposed to the first side panel 67, the second side panel 70 is also connected to the first main panel 60, the length of the second side panel 70 being less than the length of the first main panel 60 along the longitudinal axis Y. The second side panel 70, essentially parallel to the longitudinal axis Y, but located at a distance from this axis, is located close to the first auxiliary panel 61 and at a distance from the second auxiliary panel 63.

Another second side panel 71, whose length is approximately equal to the length of the second side panel 70, is connected to the second main panel 62 in a position diametrically opposed to the other first side panel 68. The second side panel 70 and the other second side panel 71 are symmetrical with respect to the first auxiliary panels 61. Thus, when folding the workpiece 59, another second side panel 71 can be superimposed on the second side panel 70 to obtain a second smaller side wall 6 of the outer shell 2. Second plate 72 connected to another second side panel 71, relative to which the second plate 72 can be folded at an angle of 90 °, so as to be between the enclosing body 14 and the upper wall 9 of the outer shell 2. The second plate 72 allows you to hide an unaesthetic empty space between the upper wall 9 and the second smaller side wall 6 of the outer shell 2 in the finished pack 1.

The first side panel 67, the other first side panel 68, the second side panel 70 and the other second side panel 71 are connected to the respective main panels 60, 62 by a plurality of folds 73 parallel to the longitudinal axis Y. The plurality of folds 73 allows folding the blank 59 to produce rounded edge zone 7 of the outer shell 2.

Between the second side panel 70 and the first main panel 60, as well as between the other second side panel 71 and the second main panel 62, through holes 74 are provided for receiving holes 12 in the outer shell 2.

The stiffening plate 75 and another stiffening plate 76 are connected respectively to the first auxiliary panel 61 and the other second auxiliary panel 64.

The shaded areas in Fig. 8 indicate gluing zones 77 for applying an adhesive to bond the desired parts of the preform 59. The two gluing zones 77 on the second sub-panel 63 allow the second sub-panel 63 to be attached to another second sub-panel 64.

Gluing zones 77 are also provided on the first side panel 67 and on the second side panel 70, allowing these panels to be attached to another first side panel 68 and another second side panel 71, respectively.

Gluing zones 77 may also be provided on another stiffening plate 76.

On the first main panel 60, a closed-line break line 78 is made, which, in accordance with the presented example, is circular. The rupture line 78 is defined by a plurality of slots 26 separated by connecting parts 79. The established rupture line 78 defines on the blank 59 an inner zone 80 located inside the rupture line 78, surrounded by an outer zone 81. The inner zone 80 allows to receive a rotary element 25 made on the finished pack 1 with the possibility of movement relative to the outer zone 81 when the connecting parts 79 are broken. In this case, the outer zone 81 acts as a support relative to which the rotary element 25 can be rotated.

The tear line 78 can be made on the first main panel 60 by the manufacturer of the workpiece 59. The tear line 78 can also be performed on the workpiece 59 during the preparatory operation carried out on a packaging machine that packs the packet 1.

On the second main panel 62, another tear line 82 can be formed, similar to the tear line 78. The break line 78 allows you to get a rotary element 25 of the connecting device 23, and the other break line 82 allows you to get a rotary element 25 of the other connecting device 24.

The distance between the tear line 78 and the first auxiliary panel 61 is substantially equal to the distance between the other tear line 82 and the first auxiliary panel 61. Thus, in the finished bundle 1, the connecting device 23 and the other connecting device 24 can have a common rotation axis X.

As shown in FIGS. 9 and 10, a fixing plate 83 is attached to the outer surface of the workpiece 59 to receive the fixing element 29 of the connecting device 23. The fixing plate 83 is attached to the area of the workpiece 59 in which the tear line 78 is made and extends beyond the line 78 breaks. In accordance with the presented example, the fixing plate 83 has a circular shape, and its diameter is larger than the diameter of the circle defined by the tear line 78. The locking plate 83 may be arranged concentrically with respect to the tear line 78.

The fixing plate 83 can be attached to the inner zone 80 by means of adhesive points 31, as already described in connection with FIG. The glue points 31 are shown in FIGS. 8-10 as shaded areas.

The fixing plate 83 can be attached to the workpiece 59 by the manufacturer of the workpiece 59, or can be glued to the workpiece 59 on a machine packing the bundle 1. In the latter case, the fixing plate 83 can be cut from a sheet of cardboard and enter the packaging machine as a pre-cut element.

Another locking plate 84, similar to the locking plate 83, can be glued to the outer surface of the large second side panel 62, forming a locking element 29 of another connecting device 24, if any.

When packing 1, the blank 41 is folded in such a way as to obtain an enclosing body 14 in which the inner wrapper 15 is placed. If necessary, an installed rupture line 78 and possibly another installed rupture line 82 are made on the blank 59.

Then, glue is applied to the bonding zones 77. At this stage, if necessary, glue points 31 are also applied. Now you can glue the fixing plate 83 and a possible other fixing plate 84 to the workpiece 59. Then, the workpiece 59 is folded around the enclosing body 14 to obtain the outer shell 2 and the finished bundle 1.

When the user first opens the package 1, the connecting parts 79 are broken, after which the rotary element 25 can freely rotate around the axis of rotation X, allowing the user to open and close the package.

11-13, a blank 159 is shown that can be folded to form an outer shell 2 in accordance with an alternative embodiment of the present invention.

The components of the workpiece 159 corresponding to the components of the workpiece 59 are denoted by the same reference numbers, but with the number “1” in front, and are not described in detail.

As such, preform 59 is a preform of the so-called longitudinally elongated type, since the main panels and auxiliary panels are arranged in series along the longitudinal axis of the main panels. On the other hand, preform 159 is a transverse-type preform in which the main panels and auxiliary panels are adjacent along the transverse axis of the main panels.

In the blank 159, the first main panel 160 and the second main panel 162 are connected by a central panel 85 for receiving a second smaller side wall 6 of the outer shell 2. The length of the central panel 85 is less than the length of the first main panel 160 and the second main panel 162.

The central panel 85 is connected to the first main panel 160 by an edge zone extending parallel to the main axis P of the first main panel 160.

The first main panel 160 and the second main panel 162 are also connected by a removable panel 86 located at the ends of the first main panel 160 and the second main panel 162 opposite the central panel 85. The removable panel 86 is connected to the first main panel 160 and the second main panel 162 along lines 87 rupture and is used to limit the deformation of the workpiece 159 when processing on a packaging machine. The user then removes the access panel 86, so that a second side opening 11 is determined.

The first stiffening panel 88 and the second stiffening panel 89 are connected to the first main panel 160 and the second main panel 162, respectively, next to the first side panel 167 and the second side panel 168. The first stiffening panel 88 and the second stiffening panel 89 are angularly folding 180 ° inward to the workpiece 159 and thus gluing respectively to the first main panel 160 and the second main panel 162. The first stiffening panel 88 and the second stiffening panel 89 provide rigidity to the free edges of the first side hole 10, preventing these edges from bending outward, impairing the appearance of packet 1.

It should also be noted that the blank 159 also contains a first auxiliary panel 90 connected to the second main panel 162 and made with the possibility of folding to bring into contact with the first auxiliary panel 161 to obtain the upper wall 9 of the outer shell 2.

The workpiece 41 and the workpiece 59 or 159 make it easy to manufacture the connecting device 23 and a possible other connecting device 24 on a slightly modified conventional packaging machine without the use of external materials other than cardboard for making a rotary connection between the outer shell 2 and the enclosing body 14.
