Description

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

A typical cigarette pack is in the form of a rectangular parallelepiped elongated along the longitudinal axis, and contains a containing body and a closing case pivotally attached to the containing body.

The enclosing housing comprises a front wall, a rear wall, two side walls and a lower wall, and the closing housing comprises a front side, a rear side, two sides and an upper side, the hinge being located between the rear wall of the enclosing housing and the rear side of the closing housing.

Users appreciate these packs for their stiffness, which eliminates cigarette damage even when they are hit or stored in a consumer’s pocket or bag.

Packs of this type are obtained from a rigid cardboard blank.

The preform has pre-weakened fold lines along which it is folded to form a bundle.

Recently, there has been a tendency to modernize ordinary packs with a hinged closing case, caused by the desire to persuade users to choose a pack that has a certain appearance, compared to packs of a more ordinary form. Thus, cigarette manufacturers are in need of changing the appearance of the package, making it possible to make the package original and more attractive to the consumer.

For this purpose, a bundle was made in which the length of the front side of the closing body, measured along the longitudinal axis, is greater than or equal to the length of the front wall of the enclosing body.

Therefore, in such a pack, the length of the sides of the closure body, measured along the longitudinal axis, is greater than the length of the sides of the lid of the conventional type.

Packages of this type are described, for example, in patent documents WO 2004/065235, WO 2009/020383, DE-A-2334190 and EP-A-0764594.

In particular, DE-A-2334190 discloses a pack comprising a holding housing for holding smoking articles and a closing housing connected to the containing housing by a hinge located at one end in the upper part of the containing housing. The closure body includes a front side and a pair of sides opposite to each other and extending from opposite edges of the front side. The sides are simple cardboard walls, the front side includes an outer wall and an inner wall that are glued to each other to increase the rigidity of the front side.

EP-A-0764594 discloses a rigid cigarette pack having a hinged lid. This pack contains a cup-shaped housing and a cup-shaped lid, which is pivotally connected to the upper open part of the housing in such a way that it can rotate between open and closed positions, respectively, closing and opening the housing. The case has a front wall, two side walls connected to the front wall by two connecting walls having a rounded cross section with a radius of rounding, which is about one and a half times the radius of a regular cigarette.

The disadvantage of the described packs is that the sides of the closure body tend to bend outward, i.e. do not retain flatness, creating problems when opening and closing the closing case and worsening the appearance of the pack.

This curvature of the side surfaces is a consequence of the reaction of the cardboard to the simple folding to which it is subjected.

In particular, an increase in the size of the sides leads to an increase in the distance between the fold lines along which they are folded, and this distance causes the curvature of the cardboard even with a moderate reaction of the material.

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

Another objective of the present invention is to provide a pack for smoking products, in particular for cigarettes, with a closing case, more rigid than in known packs.

Another objective of the present invention is to obtain a rigid pack for smoking products, containing a closure body with sides that are more rigid than in known packs.

Another object of the present invention is to provide a packet for smoking articles, in particular for cigarettes, having an enlarged surface suitable for posting messages to consumers, advertisements, and the like.

A further object of the present invention is to provide a packet for smoking articles, in particular for cigarettes, having an attractive appearance.

In accordance with a first aspect of the present invention, there is provided a pack for smoking articles, in particular for cigarettes, in accordance with the independent claim 1 of the appended claims.

The present invention allows to obtain a pack for smoking products containing a closing case, more rigid than in known packs.

In fact, the fixing parts attached, in particular glued, to the inner surface of the front side prevent and essentially eliminate the tendency of the sides to bend outward, keeping these sides essentially straight.

In addition, since these sides are formed, at least in part, by the inner and outer walls, they are more rigid, thereby improving both the appearance of the bundle and the ease of handling of the closure body.

The reinforced stiffness of the sides compared to the sides of the known packs also makes it possible to increase, in comparison with the known packs, the size of the front side compared to the front wall of the enclosing body, thereby allowing an increase in the surface suitable for placing messages for the consumer, such as advertisements etc.

In particular, such messages can be pre-printed on the fixing parts, which, in accordance with one embodiment of the invention, can significantly increase the overall width of the inner surface.

According to a second aspect of the present invention, there is provided a cardboard blank in accordance with independent claim 31 of the attached claims.

The cardboard blank proposed in accordance with the second aspect of the invention makes it easy to obtain a bundle in accordance with the first aspect of the invention on conventional machines, since this blank has an outer contour similar to the outer contour of conventional blanks.

In FIG. 1-3, a first pack 101 is provided in accordance with the present invention.

The first pack 101 is configured to accommodate smoking articles, in particular cigarettes (not shown).

The first bundle 101, which is a rigid bundle, has a substantially rectangular parallelepiped shape and is elongated along the first longitudinal axis Z1.

The first pack 101, made of, for example, hard cardboard, is configured to accommodate an ordered group of cigarettes wrapped in an inner wrapper 102, and includes a housing 103 that can hold cigarettes, and a cover body 104, or a lid that can be opened or closed, providing access to cigarettes.

In particular, the closure body 104 is movable between an open position (FIGS. 1 and 3) and a closed position (FIG. 2) by turning around a hinge 105.

The enclosing body 103 comprises a lower wall 107 and an upper wall 190 opposite the lower wall 107 (FIG. 3).

In particular, the size of the upper wall 190, measured in a plane perpendicular to the first axis Z1, is smaller than the size of the lower wall 107.

The lower wall 107 and the upper wall 190 are connected by the rear wall 109. In other words, the lower wall 107 and the upper wall 190 extend from opposite sides of the rear wall 109.

A front wall 108, opposite the rear wall 109, departs from the bottom wall 107, and the size of the rear wall 109, measured in a plane parallel to the first axis Z1, is larger than the size of the front wall 108 (Fig. 3).

Between the front wall 108 and the rear wall 109, there are two side walls 110, each of which is smaller than the size of the front wall 108 and the rear wall 109.

Each of the side walls 110 comprises a smaller portion 111 having a substantially trapezoidal shape and a larger portion 112 also having a substantially trapezoidal shape, the length of the smaller portion 111 measured in a plane parallel to the first axis Z1 being less than most of the length is 112.

In particular, the smaller portion 111 extends from the front wall 108, and the larger portion 112 extends from the rear wall 109, and the smaller portion 111 is attached, in particular glued, over the larger portion 112. In other words, the smaller portion 111 partially covers the larger portion 112.

Smaller portions 111 are connected to the front wall 108 by curved portions 113, in particular rounded portions.

In accordance with one embodiment of the invention (not shown), flat chamfers are provided instead of curved portions 113.

The closure body 104 includes an upper side 114, which in the closed position is opposite the lower wall 107, and a hinge 105 is formed between the upper side 114 and the upper wall 190.

A front side 115 is connected to the upper side 114, the length of which, measured in a plane parallel to the first axis Z1, is greater than the length of the front wall 108.

The front side 115 comprises an end portion 118 having, for example, a substantially triangular shape folded at an angle of 180 ° and attached, in particular glued, to the inner surface 119 of the front side 115, the end portion 118 reinforcing the front side 115.

Two sides 116 extend from the front side 115. The sides 116 respectively comprise expanded parts 153 having, for example, a substantially triangular shape and adjacent to the upper side 114. The sides 116 also comprise, respectively, elongated, for example, rounded, parts 154 located between the front side 115 and the expanded parts 153 and connecting the specified side with the indicated parts. Each of the sides 116 also includes a fixing part 120 connected to a corresponding elongated part 154 on a side opposite to the corresponding expanded part 153, and attached, in particular glued, to the inner surface 119.

The fixing parts 120, having, for example, an irregular pentagon shape, respectively comprise first edges 121 and second edges 122 connected to first edges 121, the first edges 121 and second edges 122 being in the closed position of the first packet 101, respectively, essentially parallel and perpendicular to the first axis Z1.

In particular, the first edges 121 are adjacent to each other, and the second edges 122 forming the “V” configuration are located adjacent to the third edges 123 of the end portion 118. Thus, the locking parts 120 extend substantially across the entire width of the closure body 104.

In addition, the locking parts 120 contain, respectively, other second edges 122 ', opposite the second edges 122. Other second edges 122', which are rectilinear, abut against the inner surface of the upper side 114. Thus, the locking parts 120 extend essentially along the entire length of the front side 115.

In accordance with one embodiment of the present invention (not shown), the other second edges 122 'are curved and, adjacent to each other, form a “gull wing” profile.

In addition, in accordance with this embodiment of the invention, the other second edges 122 'may be located at some distance from the inner surface of the upper side 114.

Each of the sides 116 comprises a stiffener 124 (FIG. 4). The stiffening elements 124 are located between the respective elongated parts 154 and the corresponding locking elements 120. In addition, the length of the stiffening elements 124, measured in a plane parallel to the first axis Z1 with the closed position of the first bundle 101, is less than the length of the elongated parts 154.

In accordance with one embodiment of the invention (not shown), the length of the stiffeners 124, measured in a plane parallel to the first axis Z1 with the closed position of the first bundle 101, is essentially equal to the length of the elongated parts 154.

As already mentioned, the stiffening elements 124 connect the elongated parts 154 with the fixing parts 120, and the elongated parts 154 and the stiffening elements 124, respectively, limit the longitudinal clearances 126 extending when the first pack 101 is closed, essentially parallel to the first axis Z1 (FIG. . four).

This leads to the fact that each of the sides 116 is formed at least partially by one outer elongated portion 154 and one inner stiffener 124.

The end portion 118 and the fixing parts 120 may be provided with printing areas indicated by a dashed line containing labels, images or other information intended for the consumer.

In the first packet 101 in accordance with the embodiment of FIG. 5, the elongated elements 154 are flat and are located at an angle α of approximately 135 ° with respect to the front side 115.

In this embodiment, the gaps 126 are limited by stiffeners 124, elongated parts 154, and an inner surface 119.

In the first packet 101 in accordance with another embodiment of FIG. 6, the elongated members 154 are flat and arranged at an angle α of approximately 90 ° with respect to the front side 115. In this embodiment, the gaps 126 are also limited by stiffeners 124, elongated portions 154, and an inner surface 119.

The first packet 101 also includes a closing wing 191 connected to the front side 115, protruding relative to the lower edge 129 of the front side 115 and located essentially in the Central zone of this lower edge.

The purpose of the closing wing 191 will be explained below. When the first packet 101 is in the closed position shown in FIG. 2, the front side 115 of the closing body 104 abuts against the front wall 108 of the housing body 103 and is essentially in the same plane with this wall. Similarly, the sides 116 are adjacent to the respective side walls 110.

In addition, the first pack 101 comprises an inner shell 106 located inside the enclosing housing 103 and partially shown in FIG. one.

As already mentioned, the inner shell 106 accommodates a group of cigarettes wrapped in the inner wrapper 102, the inner wrapper 102 containing a sheet of staniol or metal foil.

The inner wrapper 102 is a wrapper of a known type and does not have significant differences compared to the inner wrappers used in conventional cigarette packs.

The inner shell 106 includes a main wall 130, which may be provided with print areas indicated by a dashed line, which contain, for example, labels, images or other information intended for the consumer.

The main wall 130 is bounded by a U-shaped upper contour 131. Two smaller walls 132 are connected to the main wall 130, an auxiliary wall (not shown) departing from each of them.

The smaller walls 132 laterally comprise the inner wrapper 102, and the minor walls are folded behind the inner wrapper 102 so that they are adjacent to each other.

The inner shell 106 also contains two flat chamfers 133, located at an angle of, for example, approximately 135 ° with respect to the main wall 130, which connect the main wall 130 with the smaller walls 132.

Between the main wall 130 of the inner shell 106 and the front wall 108 of the housing body 103, an accommodating pocket 192 is formed, adapted to receive and hold the closing wing 191 in the closed position of the first packet 101. In particular, the accommodating pocket 192 is located between the middle part of the front wall 108 and the corresponding the middle part of the main wall 130 facing the front wall 108. In use, the closing wing 191 and the containing pocket 192 interact, holding the first pack 101 in the closed position.

The inner shell 106 also includes a lower valve (not shown) connected to the main wall 130 and bounded by a perimeter complementary to the upper circuit 131. The lower valve is folded under the inner wrapper 102. The inner shell 106 is located inside the enclosing body 103 and is attached to the rear wall 109 of the enclosing body 103.

In particular, one or more glue points may be applied to the inner surface of the back wall 109 to allow the back wall 109 to be glued to both auxiliary walls. This keeps the inner shell 106 in a closed position around the inner wrapper 102.

The first pack 101 can be used as a regular cigarette pack.

Thus, the user can open the first pack 101 by turning the closure body 104 around the hinge 105 and remove the cigarette in the same way as with conventional packs.

It should be noted that when the first packet 101 is open, the print areas on the fixing elements 120, on the end portion 118 and on the main wall 130 are visible to the user, who can thus read the labels and look at the images contained in the print areas. This provides an upgrade to the first packet 101 and an increase in the space available for posting messages to the consumer.

In fact, consumer messages and advertisements can be printed not only on the outer surfaces of the enclosing housing 103 and the closing housing 104, as in conventional bundles, but also in print areas located within the first bundle 101.

To close the first pack 101 after removing the cigarette, the user must rotate the closure housing 104 around the hinge 105 and slightly slide the closure housing 104 parallel to the first axis Z1 from the front wall 108 of the housing 103 to facilitate insertion of the closure wing 191 into the accommodating pocket 192.

The containing body 103 and the closing body 104 are formed by folding a flat blank 135 made, for example, of cardboard, passing along the first longitudinal axis of symmetry X1.

The blank 135 shown in FIG. 7 comprises a first portion 136 for forming the enclosing body 103 and a second portion 137 for forming the closure body 104.

The first part 136 and the second part 137 are connected along a predetermined fold line 138 for creating a hinge 105 in the first bundle 101. The predetermined fold line 138 may comprise a fold or be formed by a plurality of slots separated by connection points.

The blank 135 comprises a first main panel 139 designed to receive the rear wall 109 of the enclosing body 103.

The first transverse panel 140 and the second transverse panel 141 are located at opposite ends of the first main panel 139, so that the first transverse panel 140, the first main panel 139 and the second transverse panel 141 are arranged in series along the first axis of symmetry X1.

The first transverse panel 140 and the second transverse panel 141 are intended to form, respectively, the lower wall 107 and the upper wall 190 of the enclosing body 103.

A third transverse panel 142 is connected to the first transverse panel 140 to form the front wall 108 of the housing body 103, and another second transverse panel 193 is connected to the second transverse panel 141 to form the upper side 114 of the cover body 104.

Between the other second transverse panel 193 and the second transverse panel 141, a predetermined fold line 138 is formed.

A second main panel 143 is connected to another second transverse panel 193 for forming the front side 115 of the closure body 104. With a second main panel 143, in turn, a stiffener 144 is formed that can be folded at an angle of 180 ° to strengthen the front of the closure housing 104 and designed to form the end portion 118 of the closing housing 104.

The third transverse panel 142, the first transverse panel 140, the first main panel 139, the second transverse panel 141, the other second transverse panel 193, the second main panel 143 and the stiffener 144 are connected along respective transverse folds 145 extending transversely, in particular perpendicularly, to the first axis symmetry X1.

The workpiece 135 also contains a C-shaped slot 194, rotated 90 °, designed to form after folding the blanks of the closing wing 191.

In particular, the slot 194 is made adjacent to the middle zone of the transverse fold 145 separating the stiffener 144 from the second main panel 143.

The blank 135 also contains two intermediate panels 180 located on the sides of the second main panel 143 and designed to form curved elongated parts 154 of the closure body 104.

Intermediate panels 180 comprise first cut lines 151.

The first cut lines 151, essentially parallel to the first axis of symmetry X1, are located next to each other and provide folding of the intermediate panels 180.

In accordance with one embodiment of the present invention (not shown), the intermediate panels 180 do not have first cut lines 151, and longitudinal bends are present between the intermediate panels 180 and the second main panel 143.

The blank 135 also contains two first inner panels 146 located on the sides of the intermediate panels 180 and designed to form the stiffening elements 124 of the closure body 104.

Between the intermediate panels 180 and the first inner panels 146, there are first longitudinal folds 150 extending substantially parallel to the first axis of symmetry X1.

The blank 135 also contains two first outer panels 149 located on the sides of the first inner panels 146 and separated from the latter by second longitudinal folds 152 extending essentially parallel to the first axis of symmetry X1, the first outer panels 149 being designed to form the fixing parts 120.

Thus, the first inner panels 146 are bounded by first and second longitudinal folds 150, 152.

The blank 135 also contains two second inner panels 147 located between the intermediate panels 180, the first inner panels 146 and the first outer panels 149 and designed to form the expanded parts 153 of the cover body 104.

Each of the second inner panels 147 is separated from the corresponding first inner panel 146 and the first outer panel 149 by an inclined slot 148.

On the sides of the other second transverse panel 193, the first wings 155 protrude, folding inside another second transverse panel 193 and gluing to the second inner panels 147 to stiffen the expanded parts 153.

In particular, between the first wings 155 and the other second transverse panel 193, there are third longitudinal folds 156 extending substantially parallel to the first axis of symmetry X1.

The blank 135 also contains two second outer panels 157 located on the sides of the first main panel 139 and separated from the latter by longitudinal folds 158 extending substantially parallel to the first axis of symmetry X1.

In particular, the second outer panels 157 are intended to form large portions 112 of the side walls 110 of the housing body 103.

Connected to the ends of the second outer panels 157 are second wings 159 configured to fold inwardly the second outer panels 157 and adhere to the first transverse panel 140 to stiffen the bottom wall 107.

The other second wings 195 are connected to opposite ends of the second outer panels 157 opposite the wings 195. The other second wings 195 are arranged to fold inwardly the second outer panels 157 and adhere to the second transverse panel 141 to stiffen the upper wall 190.

On the sides of the third transverse panel 142 protrude third wings 160, made with the possibility of folding inside the third transverse panel 142 and glued to the second outer panel 157 to form smaller parts 111 of the side walls 110 of the housing body 103.

In particular, between the third wings 160 and the third transverse panel 142, there are connecting panels 181 for forming the curved portions 113.

The connection panels 181 comprise second cut lines 161. The second cut lines 161, essentially parallel to the first axis of symmetry X1, are located next to each other and provide folding of the connecting panels 181.

In accordance with one embodiment of the present invention (not shown), the connecting panels 181 do not contain second cut lines 161 and are limited to two longitudinal folds.

After applying the adhesive, the preform 135 is folded in the usual sequence because the preform 135 does not contain additional panels compared to conventional preforms. Consequently, the preform 135 can be processed on a conventional machine for manufacturing hard cigarette packs.

In FIG. 8 shows an inner frame 163 that can be used to form the inner shell 106.

The inner frame 163 may be made of cardboard, possibly connected to a metal sheet, such as aluminum.

The inner frame 163 may be formed on the packaging machine from rolled material cut with a knife having a U-shaped profile corresponding to the upper transverse profile 164 and the lower transverse profile 165 of the inner frame 163.

Two outer weakening lines 167 and two intermediate weakening lines 168 are also obtained on the inner frame 163 by means of corresponding cutters, the outer weakening lines 167 being formed outside the inner weakening lines 166.

The transverse attenuation line 169, located transversely with respect to the inner, intermediate and outer attenuation lines 166, 168 and 167, is made in the lower part of the inner frame 163.

Between the inner weakening lines 166 and the transverse weakening line 169, a main panel 170 is formed for forming the main wall 130 of the inner shell 106.

On the sides of the main panel 170 there are two side panels 171, each of which is located between the inner weakening line 166 and the intermediate weakening line 168. Each of the side panels 171 is intended to form a chamfer 133 of the inner shell 106.

On the sides of the side panels 171 there are two intermediate panels 172, each of which is located between the intermediate weakening line 168 and the outer weakening line 167.

Each of the intermediate panels 172 is designed to form a smaller wall 132 of the inner shell 106.

On the outer sides of the intermediate panels 172, there are two edge panels 173, each of which is connected to a respective intermediate panel 172 via an outer attenuation line 167. The edge panels 173 are folded inwardly of the inner wrapper 102 to form auxiliary walls.

Thus, the inner frame 163 after folding surrounds the inner shell 106 on four sides.

Between the transverse weakening line 169 and the lower transverse profile 165, an end panel 174 is formed which can be folded under the inner wrap 102 to form a lower valve.

In the packaging process, the inner frame 163 is folded around the inner wrapper 102 and glued to it using glue points located in the same way as on conventional inner frames.

The inner frame 163 can be folded around the inner wrapper 102 using a folding unit, similar to that used for conventional inner frames.

Then, the containing body 103 and the closing body 104 are formed by folding the workpiece 135 around the inner shell 106.

In addition, the fixing parts 120 of the pack 101d contain, respectively, other second edges 122 'opposite to the second edges 122.

The other second edges 122 'are curved, adjacent to each other, form a gull wing profile, and are located at some distance from the inner surface of the upper side 114.

According to one embodiment of the bundle 101d (not shown), the other second edges 122 'are straight and abut against the inner surface of the upper side 114.

According to another embodiment of the bundle 101d (not shown), the first edges are spaced apart, leaving the intermediate parts of the inner surface 119 free. In use, the closing wings 128 and the pockets 134 interact to hold the bundle 101d in the closed position.

In order to close the pack 101d after removing the cigarette, the user must rotate the closure body 104 around the hinge 105 and slightly slide the closure housing 104 parallel to the first axis Z1 from the front wall 108 of the housing body 103 to facilitate insertion of the closing wings 128 into the accommodating pockets 134.

20, reference numeral 101e indicates a fourth embodiment of a first packet 101 of smoking articles in accordance with the present invention.

In particular, the pack 101e belongs to the type of packs with rounded corners. Elements of the packet 101e, similar to the elements of the first packet 101, are denoted by the same reference numerals and are not described here for brevity.

In particular, the pack 101e does not contain an upper wall 190, and a hinge 105 is formed between the rear side 115 'opposite the front side 115, the closure body 104 and the rear wall 109 of the enclosing body 103.

On Fig and 22 presents a second pack 201 for smoking articles, in particular cigarettes, in accordance with the second embodiment of the present invention.

The second pack 201, also of a rigid type, has the shape of a substantially rectangular parallelepiped and extends along the second longitudinal axis Z2.

In particular, the second pack 201 belongs to the type of packs with rounded corners.

A second pack 201, made of, for example, hard paperboard, is configured to accommodate an ordered group of cigarettes wrapped in an inner wrapper 202, and includes a housing 203 that can hold cigarettes and a cover 204 or a lid that can be opened or closed, providing access to cigarettes.

In particular, the closure body 204 is movable between the open position (FIG. 21) and the closed position (FIG. 22) by turning around the hinge 205 of FIG. 21.

The enclosing body 203 comprises a bottom wall (not shown), from which a back wall (not shown) extends. Two side walls 210 extend from opposite sides of the rear wall.

The side walls 210 have a substantially trapezoidal shape, and their size is smaller than the size of the rear wall. In particular, the side walls 210 are connected to the rear wall by curved, in particular rounded, parts 213.

In accordance with one embodiment of the present invention (not shown), flat chamfers are provided instead of curved parts 213.

From the rear wall, from the side opposite the lower wall, the upper wall 299, having, for example, a shaped profile, departs.

In particular, when the second pack 201 is closed, the lower wall is opposite to the upper wall 299.

The closure body 204 comprises an upper side 214, which, in the closed position, is opposite to the lower wall and faces the upper wall 299.

Connected to the upper side 214 is the front side 215, the length of which when the second pack 201 is closed, measured in a plane parallel to the second axis Z2, is substantially equal to the length of the rear wall.

In particular, when the second pack 201 is closed, the front side 215 is opposite the rear wall, and the length of the front side 215, measured in a plane parallel to the second axis Z2, is substantially equal to the length of the rear wall.

A hinge 205 is formed between the front side 215 and the lower wall.

Two sides 216 extend from the front side 215. The sides 216 respectively comprise enlarged portions 253 having a substantially triangular shape and adjacent to the upper side 214.

The sides 216 also contain corresponding elongated parts 254, for example, rounded, located between the front side 215 and the expanded parts 253 and connecting this side with these parts 253.

Each of the sides 216 also includes a fixing part 220 connected to a corresponding elongated part 254 on a side opposite the corresponding expanded part 253, and attached, in particular glued, to the inner surface 219 of the front side 215.

The locking parts 220 extend substantially along the entire length of the front side 215.

In addition, the fixing parts 220, having, for example, a rectangular trapezoidal shape, respectively comprise first edges 221 extending when the second pack 201 is closed, essentially parallel to the second axis Z2.

In particular, the first edges 221 are adjacent to each other, as a result of which the locking parts 220 extend substantially over the entire width of the closure body 204.

In accordance with one embodiment of the invention (not shown), the first edges 221 are at some distance from each other, leaving the middle parts of the inner surface 219 free.

Each of the sides 216 comprises a stiffener 224 (FIG. 23).

The stiffening elements 224 are located between the respective elongated parts 254 and the corresponding locking parts 220.

In addition, the length of the stiffening elements 224, measured in a plane parallel to the second axis Z2, is less than the length of the elongated parts 254.

In accordance with one embodiment of the invention (not shown), the length of the stiffening elements 224, measured in a plane parallel to the second axis Z2, is equal to the length of the elongated parts 254.

As already mentioned, the stiffening elements 224 connect the elongated parts 254 with the fixing parts 220, the elongated parts 254 and the stiffening elements 224 defining the corresponding longitudinal gaps 226 extending when the second pack 201 is closed, essentially parallel to the second axis Z2.

Thus, each of the sides 216 is formed, at least in part, by an outer elongated portion 254 and an inner stiffener 224.

The fixing portions 220 may include print areas indicated by dashed lines that contain, for example, labels, images, or other information for the user.

According to an embodiment of the second stack 201 shown in FIG. 24, the elongated portions 254 are flat and are located at an angle α of approximately 135 ° with respect to the front side 215.

In this embodiment, the gaps 226 are limited by stiffeners 224, elongated portions 254, and an inner surface 219.

In another embodiment of the second pack 201 shown in FIG. 25, the elongated portions 254 are flat and are located at an angle α of approximately 90 ° with respect to the front side 215.

In this embodiment, the gaps 226 are also limited by stiffeners 224, elongated portions 254, and an inner surface 219.

When the second pack 201 is in the closed position of FIG. 22, the upper side 214 of the closure housing 204 is flush with the rear wall of the enclosing housing 203, and the sides 216 are adjacent to the corresponding side walls 210.

The second pack 201 also contains an inner shell 206 located inside the enclosing housing 203 and shown in detail in FIG. 26-28.

As already mentioned, the inner shell 206 accommodates a group of cigarettes wrapped in an inner wrapper 202 containing a sheet of stanoli or metal foil. The inner wrapper 202 is a wrapper of a known type and has no significant differences compared to the inner wrappers used in conventional cigarette packs.

The inner shell 206 comprises a main wall 230, which may be provided with printing areas indicated by a dashed line (Fig. 21), containing, for example, labels, images or other information for the user.

The main wall 230 is bounded by a U-shaped upper contour 231. Two smaller walls 232 are connected to the main wall 230, an auxiliary wall 298 departing from each of them.

The smaller walls 232 laterally comprise the inner wrapper 202, and the auxiliary walls 298 are folded behind the inner wrapper 202.

In addition, the inner shell 206 contains two flat chamfers 233 located at an angle of, for example, approximately 135 ° with respect to the main wall 230, which connect the main wall 230 to the smaller walls 232.

From the chamfers 233 close to the upper contour 231, two closing wings 297 protrude outwardly made to engage the closing body 204 to hold the closing body 204 in the closed position.

The inner shell 206 also includes a lower valve 296 connected to the main wall 230 and bounded by a perimeter that complements the upper circuit 231. The lower valve 296 is folded under the inner wrap 202.

The inner shell 206 also contains two upper valves 295, each of which is connected to a corresponding smaller wall 232.

In particular, the upper flaps 295 are folded above the inner wrap 202 so as to hold the latter from above.

The inner shell 206 is located inside the enclosing body 203 and is attached to the side walls 210 of the enclosing body 203.

In particular, one or more glue points may be applied to the inner surface of the side walls 210 to allow the side walls 210 to be glued to the corresponding smaller walls 232. This ensures that the inner shell 206 is held in a closed position around the inner wrapper 202.

The second pack 201 can also be used as a regular cigarette pack.

Thus, the user can open the second pack 201 by turning the closure body 204 around the hinge 205 and remove the cigarette in the same way as with conventional packs.

It should be noted that when the second pack 201 is open, the print areas on the fixing elements 220 and on the main wall 230 are visible to the user, who can thus read the labels and look at the images contained in the print areas. This provides for the modernization of the second packet 201 and an increase in the space available for posting messages to the consumer.

In fact, consumer messages and advertisements can be printed not only on the outer surface of the containing housing 203 and the closing housing 204, but also in the printing areas located inside the second pack 201.

To close the second pack 201 after removing the cigarette, the user must rotate the closure body 204 around the hinge 205 until the closure body 204 engages with the closing wings 297.

The containing body 203 and the closing body 204 are formed by folding a flat blank 235 made, for example, of cardboard, passing along the second longitudinal axis of symmetry X2.

The blank 235 shown in FIG. 29, comprises a first part 236 for receiving a housing body 203, and a second part 237 for receiving a housing body 204.

The first part 236 and the second part 237 are connected along a predetermined fold line 238 for creating a hinge 205 in the second bundle 201. The predetermined fold line 238 may comprise a fold or be formed by a plurality of slots separated by connection points. The blank 235 comprises a first main panel 239 designed to receive the rear wall of the enclosing body 203.

The first transverse panel 240 is for forming the lower wall, and the second transverse panel 241 is for receiving the upper wall 299 of the housing body 203.

A second main panel 243 is connected to the first transverse panel 240 for forming the front side 215 of the closure body 204, and a predetermined fold line 238 passes between the first transverse panel 240 and the second main panel 243.

A third transverse panel 242 is connected to the second main panel 243 to form the upper side 214 of the closure body 204.

The third transverse panel 242, in turn, is connected with a reinforcing wing 244, configured to fold at an angle of 180 ° to strengthen the part of the closing housing 204, designed to form the upper side 214.

The reinforcing wing 244, the third transverse panel 242, the second main panel 243, the first transverse panel 240, the first main panel 239 and the second transverse panel 241 are connected along respective transverse folds 245 located transversely, in particular perpendicularly, to the second axis of symmetry X2.

In addition, the workpiece 235 contains two intermediate panels 280 located on the sides of the second main panel 243 and designed to form curved elongated parts 254 of the cover body 204.

Intermediate panels 280 comprise first cut lines 251.

The first cut lines 251, essentially parallel to the second axis of symmetry X2, are located next to each other and provide folding of the intermediate panels 280.

In accordance with one embodiment of the present invention (not shown), the intermediate panels 280 do not have first cut lines 251, and there are longitudinal folds between the intermediate panels 280 and the second main panel 243.

The blank 235 also contains two first inner panels 246 located on the sides of the intermediate panels 280 and designed to form the stiffening elements 224 of the closure body 204.

Between the first inner panels 246 and the intermediate panels 280, there are first longitudinal folds 250 extending substantially parallel to the second axis of symmetry X2.

In addition, the workpiece 235 contains two first outer panels 249 located on the sides of the first inner panels 246 and separated from the latter by second longitudinal folds 252, extending essentially parallel to the second axis of symmetry X2, the first outer panels 249 designed to form the fixing parts 220 .

Thus, the first inner panels 246 are bounded by the first and second longitudinal folds 250, 252.

The blank 235 also contains two second inner panels 247 located between the intermediate panels 280, the first inner panels 246 and the first outer panels 249 and designed to form the expanded parts 253 of the closure body 204.

Each of the second inner panels 247 is separated from the corresponding first inner panel 246 and the first outer panel 249 by an inclined slot 248.

On the sides of the third transverse panel 242 protrude the first wings 255, made with the possibility of folding inside the third transverse panel 242 and glued to the second inner panels 247 to give rigidity to the expanded parts 253.

In particular, between the first wings 255 and the third transverse panel 242, there are third longitudinal folds 256 extending substantially parallel to the second axis of symmetry X2.

The blank 235 also contains two second outer panels 257 located on the sides of the first main panel 239.

In particular, between the second outer panels 257 and the first main panel 239, there are connecting panels 281 for forming curved parts 213.

In particular, the connection panels 281 comprise second cut lines 261. The second cut lines 261, essentially parallel to the second axis of symmetry X2, are located next to each other and provide folding of the connecting panels 281.

In accordance with one embodiment of the present invention (not shown), the connecting panels 281 do not contain second cut lines 261 and are limited to two longitudinal folds.

Connected to the ends of the second outer panels 257 are second wings 259 configured to fold inwardly the second outer panels 257 and adhere to the first transverse panel 240 to stiffen the bottom wall.

After applying the adhesive, the preform 235 is folded in the usual sequence, since the preform 235 does not contain additional panels compared to conventional preforms. Therefore, the preform 235 can be processed on a conventional machine for manufacturing hard cigarette packs.

On Fig presents the inner frame 263, which can be used to form the inner shell 206.

The inner frame 263 may be made of cardboard, possibly connected to a metal sheet, such as aluminum.

The inner frame 263 can be formed directly on the packaging machine from rolled material cut with a knife having a U-shaped profile corresponding to the upper transverse profile 264 and the lower transverse profile 265 of the inner frame 263.

Two inner weakening lines 266, two outer weakening lines 267 and two intermediate weakening lines 268 are also formed on the inner frame 263 by appropriate cutters, the outer weakening lines 267 being formed outside the inner weakening lines 266.

Also, in the lower part of the inner frame 263, a transverse attenuation line 269 is formed, extending transversely with respect to the inner, intermediate, and outer attenuation lines 266, 268, and 267.

Another transverse attenuation line 290 extends laterally with respect to the inner, intermediate, and outer attenuation lines 266, 268, and 267 at the top of the inner frame 263.

Between the inner weakening lines 266 and the transverse weakening line 269, a main panel 270 is formed for forming the main wall 230 of the inner shell 206.

On the sides of the main panel 270 there are two side panels 271, each of which is located between the inner weakening line 266 and the intermediate weakening line 268. Each of the side panels 271 is intended to form a chamfer 233 of the inner shell 206.

On the sides of the side panels 271 there are two intermediate panels 272, each of which is located between the intermediate weakening line 268 and the outer weakening line 267.

Each of the intermediate panels 272 is designed to form a smaller wall 232 of the inner shell 206.

In addition, on the outer sides of the intermediate panels 272, there are two external panels 273, each of which is connected to a respective intermediate panel 272 via an outer attenuation line 267. The outer panels 273 are folded inwardly of the inner wrapper 202 to form auxiliary walls 298.

Thus, the inner frame 263 after folding surrounds the inner shell 206 on four sides.

Between the transverse weakening line 269 and the lower transverse profile 265, an end panel 274 is formed which can be folded under the inner wrap 202 to obtain a lower valve 296.

Also, between the other transverse weakening line 290 and the upper transverse profile 264, other end panels 289 are formed which are capable of folding over the inner wrap 202 to obtain upper valves 295.

In addition, two other C-shaped slots 288 are provided on the inner frame 263 for forming the closing wings 297.

In the packaging process, the inner frame 263 is folded around the inner wrapper 202 and glued to it using glue points located in the same way as on conventional inner frames.

The inner frame 263 can be folded around the inner wrapper 202 using a folding unit, similar to that used for conventional inner frames.

Then, the containing body 203 and the closing body 204 are formed by folding the workpiece 235 around the inner shell 206.

From the above description it is clear that the second pack 201 can be made using conventional packaging machines, essentially no different from existing ones.

On Fig-38 presents the third pack 301 for smoking articles, in particular for cigarettes, in accordance with the third embodiment of the present invention.

The third packet 301, also of a rigid type, has the shape of a substantially rectangular parallelepiped and extends along the third longitudinal axis Z3.

A third pack 301, made of, for example, hard cardboard, is configured to accommodate an ordered group of cigarettes wrapped in an inner wrapper 302, and includes a housing 303 that can hold cigarettes and a cover case 304 that can be opened or closed, providing access to cigarettes.

The enclosing body 303 comprises a lower wall 307 having, for example, a shaped profile from which the rear wall 309 extends. Two side walls 310 extend from opposite sides of the rear wall 309.

The side walls 310 have a substantially trapezoidal shape, and their size is smaller than the size of the rear wall 309.

From the rear wall 309, from the side opposite the lower wall 307, the upper wall 399, having, for example, a shaped profile, departs.

In particular, when the third pack 301 is closed, the bottom wall 307 is opposite the top wall 399.

The closure body 304 includes a main body 392 slidingly connected, as will be described in detail below, with the housing body 303, and a cover 396.

In particular, the main body 392, which interacts with the accommodating body 303 for holding smoking articles, is connected to the cover 396 by a hinge 305, and the cover 396 is movable between the open position (Fig. 33) and the closed position (Fig. 31) by turning around hinge 305.

The cover 396 comprises an upper side 314, which, when closed, is opposite the lower wall 307 and faces the upper wall 399.

Connected to the upper side 314 is a front side 315, the length of which when the third pack 301 is closed, measured in a plane parallel to the third axis Z3, is substantially less than the length of the rear wall 309.

In particular, when the third pack 301 is closed, the front side 315 is opposite to the rear wall 309.

Two sides 316 extend from the front side 315. The sides 316 respectively comprise expanded parts 353 having, for example, a substantially trapezoidal shape and adjacent to the upper side 314.

The sides 316 also contain corresponding elongated, for example rounded, parts 354 located between the front side 315 and the expanded parts 353 and connecting the front side 315 with the expanded parts 353.

The main body 392 also includes a front side 387 opposite the rear wall 309.

A hinge 305 is formed between the other front side 387 and the front side 315.

Two other lateral sides 389 extend from opposite sides of the other front side 387, the front side 387 and the other sides 389 forming a lower profile 388, complementing the lower profile of the lower wall 307.

The size of each of the other sides 389 is smaller than the size of the front side 387.

In particular, each of the other sides 389 comprises a corresponding other elongated portion 386.

Each of the other elongated parts 386 comprises a first part 385, for example, rounded, connected to the other front side 387, and a second part 384, for example, essentially flat, connected to the corresponding first part 385.

Each of the other sides 389 also includes a fixing part 320 (FIG. 34) connected to a corresponding other elongated part 386 and attached, in particular glued, to the inner surface 319 of the other front side 387.

The fixing portions 320 extend substantially along the entire length of the other front side 387.

The locking parts 320, for example, having the shape of a rectangle, respectively comprise first edges 321 extending when the third bundle 301 is closed, substantially parallel to the third axis Z3.

In particular, the first edges 321 are adjacent to each other, as a result of which the locking parts 320 extend substantially over the entire width of the closure body 304.

In accordance with one embodiment of the invention (not shown), the first edges 321 are spaced apart, leaving the middle parts of the inner surface 319 free. Each of the other sides 389 includes a stiffener 324 (FIG. 34).

The stiffening elements 324 are located between the respective other elongated parts 386 and the corresponding fixing parts 320.

In particular, the stiffening elements 324 are located between the respective second parts 384 and the corresponding fixing parts 320.

Also, the length of the stiffening elements 324, measured in a plane parallel to the third axis Z3, is essentially equal to the length of the other elongated parts 386.

As already mentioned, the stiffening elements 324 connect the other elongated parts 386 with the fixing parts 320, the other elongated parts 386 and the stiffening elements 324 defining the corresponding longitudinal gaps 326 extending when the third pack 301 is closed, essentially parallel to the third axis Z3.

Thus, each of the other sides 389 is formed, at least in part, by another outer elongated portion 386 and an inner stiffener 324.

The fixing portions 320 may include print areas (not shown) containing, for example, labels, images, or other information for the user.

In one embodiment of the third bundle 301 (not shown), the other elongated portions 386 are flat and positioned at an angle of approximately 135 ° with respect to the other front side 387.

In this embodiment, the gaps 326 are limited by stiffeners 324, other elongated parts 386, and an inner surface 319.

In another embodiment of the third bundle 301 (not shown), the other elongated portions 386 are flat and are located at an angle of approximately 90 ° with respect to the other front side 387.

In this embodiment, the gaps 326 are also limited by stiffeners 324, other elongated portions 386, and an inner surface 319.

When the third pack 301 is in the closed position of FIGS. 31 and 32, the upper side 314 of the lid 396 is flush with the rear wall 309 of the enclosing body 303, and the sides 316 are adjacent to the corresponding side walls 310 and are substantially in the same plane with them.

In particular, the sides 316 and other sides 389 are adjacent.

In addition, when the third pack 301 is closed, the lower profile 388 is adjacent and substantially lies in the same plane with the lower wall 307.

The third pack 301 also contains an inner shell 306 located inside the enclosing housing 303.

As already mentioned, the inner shell 306 accommodates a group of cigarettes wrapped in an inner wrapper 302 containing a sheet of styrene or metal foil. The inner wrapper 302 is a wrapper of a known type and does not have significant differences compared to the inner wrappers used in conventional cigarette packs.

The inner shell 306 includes a main wall 330, which may be provided with printing areas (not shown), containing, for example, labels, images or other information for the user.

The main wall 330 is bounded by a U-shaped upper contour 331. Two smaller walls 332 are connected to the main wall 330, an auxiliary wall (not shown) departing from each of them.

The smaller walls 332 laterally comprise the inner wrapper 302, and the auxiliary walls are folded behind the inner wrapper 302.

The inner shell 306 also contains two flat chamfers 333, inclined with respect to the main wall 330 and connecting the main wall 330 with smaller walls 332.

From the outer corners 380 of the chamfers 333, close to the upper contour 331, two closing wings 397 protrude outwardly made with engagement cutouts 399 'contained in the cover 396 to hold it closed.

The inner shell 306 also contains other wings 382 (FIGS. 35 and 36) located lower than the closing wings 397 and protruding outward from the inner corners 379 of the chamfers 333, the inner corners 379 being closer to the third axis Z3 than the outer corners 380.

In particular, there are two pairs of other wings 382 located at a certain distance one above the other along the third axis Z3.

Other wings 382 are adapted to engage with longitudinal passages 378 (Fig. 36) made between stiffeners 324 and fixing parts 320, with longitudinal passages 378 extending substantially parallel to the third axis Z3.

In other words, when used, other wings 382 are held inside the longitudinal passages 378 and slide longitudinally in these passages.

This provides a sliding connection of the housing 304 to the enclosing housing 303.

The inner shell 306 also includes a bottom valve (not shown) connected to the main wall 330 and bounded by a perimeter complementary to the upper circuit 331. The bottom valve is folded under the inner wrap 302.

The inner shell 306 also contains two upper valves (not shown), each of which is connected to a corresponding smaller wall 332.

In particular, the upper flaps are folded over the inner wrapper 302 so as to hold the latter from above.

The inner shell 306 is located inside the enclosing body 303 and is attached to the rear wall 309 and / or side walls 310 of the enclosing body 303.

In particular, one or more glue points may be applied to the inner surface of the rear wall 309 and / or to the inner surfaces of the side walls 310, allowing the rear wall 309 and / or side walls 310 to be glued to the corresponding auxiliary wall and to the smaller wall 332, respectively. This maintains the closed position of the inner shell 306 around the inner wrapper 302.

The third pack 301 can also be used as a regular cigarette pack.

Thus, the user can open the third pack 301 by turning the lid 396 around the hinge 305 and remove the cigarette in the same way as with conventional packs.

To close the third pack 301 after removing the cigarette, the user must turn the lid 396 around the hinge 305 until the lid 396 engages with the closing wings 397.

Alternatively, as already mentioned, the user can move the closure body 304 relative to the enclosing body 303, holding the enclosing body 303 with one hand and holding the closure body 304 with the other hand, applying a cutting force to the latter, by which the closure body 304 slides relative to the enclosing body 303 Thus, the closing body 304 slides relative to the containing body 303, and the closing body 304 remains attached to the inner shell 306, due to the engagement of other wings to 382 with a respective longitudinal passageways 378.

Thus, the user can slide the closure body 304, to which the cover 396 is attached, relative to the containing body 303. The cover 396 moves away from the rear wall 309 of the containing body 303.

In particular, the closure body 304 may slide relative to the enclosing body 303 until the two lowermost other wings 382 abut against the first end zones of the longitudinal passages 378 located closer to the bottom wall 307 of the enclosing body 303, such first end zones acting as stops, or end stops, for such a pair of other wings 382.

After the at least partial closure of the housing 304 is moved relative to the housing 303, which allows the lid 396 to rotate around the hinge 305, the user can take out cigarettes. After removing one or more cigarettes, the user can again slide the closure body 304 relative to the enclosing body 303 until the topmost pair of other wings 382 abuts against the second end zones of the longitudinal passages 378 opposite the first end zones, these second end zones also acting as stops, or end stops, for this pair of other wings 382.

The user can then close the lid 396, which is held closed by the closing wings 397 interacting with the cutouts contained in the lid 396, so that the third packet 301 again takes the form of a conventional rigid packet.

It should be noted that the containing body 303 and the closing body 304 are separated along the longitudinal plane of the third packet 301 containing the third axis Z3, and can slide in this plane.

It should also be noted that when the third pack 301 is in the open position, the print areas on the fixing parts 320 and on the main wall 303 are visible to the user, who can thus read the labels and look at the images contained in the print areas. This provides for the modernization of the third packet 301 and an increase in the space available for posting messages to the consumer.

In fact, consumer messages and possible advertisements can be printed not only on the outer surface of the containing housing 303 and the closing housing 304, as in conventional bundles, but also in the printing areas located inside the third bundle 301.

The containing body 303 and the closing body 304 are formed by folding a flat blank 335 made, for example, of cardboard, passing along the third longitudinal axis of symmetry X3.

The blank 335 shown in FIG. 39 comprises a first portion 336 for forming the enclosing body 303 and a second part 337 for forming the closure body 304.

The first part 336 and the second part 337 are connected along a predetermined cut line 317, along which the workpiece 335 is sequentially cut to separate the accommodating body 303 from the closure body 304. The blank 335 also includes a first main panel 339 for receiving the rear wall 309 of the containing body 303.

The first transverse panel 340 and the second transverse panel 341 are located at opposite ends of the first main panel 339, so that the first transverse panel 340, the first main panel 339 and the second transverse panel 341 are arranged in series along the third axis of symmetry X3. The first transverse panel 340 is for forming the lower wall 307, and the second transverse panel 341 is for forming the upper wall 399 of the enclosing body 303.

A second main panel 343 is connected to the first transverse panel 340 for forming the other front side 387 of the cover body 304, and a predetermined cut line 317 passes between the first transverse panel 340 and the second main panel 343.

A third transverse panel 342 is connected to the second main panel 343 for forming the upper side 314 of the cover 396, and a fourth transverse panel 377 is located between the second main panel 343 and the third transverse panel 342 for forming the front side 315 of the cover 396.

The third transverse panel 342, in turn, is connected to a reinforcing wing 344, configured to fold 180 ° to strengthen the part of the cover 396, designed to form the upper side 314.

The second main panel 343 and the fourth transverse panel 377 are connected along a predetermined line 338, designed to create a hinge 305 in the third bundle 301.

The predetermined fold line 338 may comprise a fold or be formed by a plurality of slots separated by connection points.

The reinforcing wing 344 and the third transverse panel 342, the third transverse panel 342 and the fourth transverse panel 377, the first transverse panel 340 and the first main panel 339, the first main panel 339 and the second transverse panel 341 are connected at respective transverse folds 345 located transversely, in particular perpendicular to the third axis of symmetry X3.

The blank 335 also includes two intermediate panels 380 located on the sides of the second main panel 343 and designed to form other elongated parts 386 of the main body 392. The intermediate panels 380 contain the first cut lines 351.

The first cut lines 351, essentially parallel to the third axis of symmetry X3, are located next to each other and provide folding of the intermediate panels 380 to form the first parts 385.

According to one embodiment of the present invention (not shown), the intermediate panels 380 do not have first cut lines 351, and longitudinal folds are provided between the intermediate panels 380 and the second main panel 343.

The blank 335 also includes two first inner panels 346 located on the sides of the intermediate panels 380 and designed to form the stiffening elements 324 of the closure body 304.

Between the first inner panels 346 and the intermediate panels 380, there are first longitudinal folds 350 extending substantially parallel to the third axis of symmetry X3.

The blank 335 also contains two first outer panels 349 located on the sides of the first inner panels 346 and separated from the latter by second longitudinal folds 352 extending essentially parallel to the third axis of symmetry X3, the first outer panels 349 being designed to form fixing parts 320.

Thus, the first inner panels 346 are bounded by the first and second longitudinal folds 350, 352.

The blank 335 also contains essentially straight slots 376 made in the second longitudinal folds 352 and designed to form longitudinal passages 378.

On the sides of the fourth transverse panel 377 protrude panels 347, designed to form the expanded parts 353 of the cover 396.

In particular, between the panels 347 and the fourth transverse panel 377, there are other intermediate panels 393.

Other intermediate panels 393 comprise other first cut lines 391.

The other first cut lines 391, substantially parallel to the third axis of symmetry X3, are adjacent to each other and provide folding of the other intermediate panels 393 to form elongated portions 354 of the sides 316.

On the sides of the third transverse panel 342 protrude the first wings 355, made with the possibility of folding inward the third transverse panel 342 and glued to the panels 347 to give rigidity to the expanded parts 353.

In particular, between the first wings 355 and the third transverse panel 342, there are third longitudinal folds 356 extending substantially parallel to the third axis of symmetry X3.

Also, in the first wings 355, cuts 375 are made, having the shape of triangles with rounded peaks, which are intended to form cutouts 399 '.

The blank 335 also comprises two second outer panels 357 located on the sides of the first main panel 339.

Connected to the ends of the second outer panels 357 are second wings 359 configured to fold inwardly the second outer panels 357 and adhere to the first transverse panel 340 to stiffen the bottom wall 307.

After applying the adhesive, the preform 335 is folded in the usual sequence, since this preform does not contain additional panels compared to conventional preforms. Consequently, the preform 335 can be processed on a conventional hard cigarette pack making machine.

On Fig presents the inner frame 363, which can be used to form the inner shell 306.

The inner frame 363 may be made of cardboard, possibly connected to a metal sheet, such as aluminum.

The inner frame 363 can be formed directly on the packaging machine from rolled material cut with a knife having a shaped profile corresponding to the upper transverse profile 364 and the lower transverse profile 365 of the inner frame 363.

Two inner weakening lines 366, two outer weakening lines 367 and two intermediate weakening lines 368 are also formed on the inner frame 363 by appropriate cutters, the outer weakening lines 367 being formed outside the inner weakening lines 366.

Also in the lower part of the inner frame 363, a transverse attenuation line 369 is formed, extending transversely with respect to the inner, intermediate, and outer attenuation lines 366, 368, and 367.

Another transverse attenuation line 390 extends laterally with respect to the inner, intermediate, and outer attenuation lines 366, 368, and 367 at the top of the inner frame 363.

Between the inner weakening lines 366 and the transverse weakening line 369, a main panel 370 is formed for forming the main wall 330 of the inner shell 306.

On the sides of the main panel 370, there are two side panels 371, each of which is located between the inner attenuation line 366 and the intermediate attenuation line 368. Each of the side panels 371 is intended to form a chamfer 333 of the inner shell 306.

On the sides of the side panels 371 there are two intermediate panels 372, each of which is located between the intermediate attenuation line 368 and the outer attenuation line 367.

Each of the intermediate panels 372 is designed to form a smaller wall 332 of the inner shell 306.

In addition, on the outer sides of the intermediate panels 372, there are two external panels 373, each of which is connected to a respective intermediate panel 372 via an external attenuation line 367.

Outer panels 373 are folded behind the inner wrapper 302 to form auxiliary walls.

Thus, the inner frame 363 after folding surrounds the inner shell 306 on four sides.

Between the transverse weakening line 369 and the lower transverse profile 365, an end panel 374 is formed which can be folded under the inner wrap 302 to form a lower valve.

Also between the weakening transverse line 390 and the upper transverse profile 364, other end panels 389 are formed which can be folded over the inner wrap 302 to obtain upper valves.

In addition, on the inner frame 363, in particular along the intermediate attenuation line 368, next to the upper transverse profile 364, two other C-shaped slots 388 are provided for forming the closing wings 397.

In addition, on the inner frame 363, in particular along the inner attenuation line 366, four other C-shaped slots 394 are formed next to the upper transverse profile 364, which are intended to form other wings 382.

During packaging, the inner frame 363 is folded around the inner wrapper 302 and glued to it using glue points located in the same way as on conventional inner frames.

Figures 41-46 show a fourth pack 401 for smoking articles, in particular for cigarettes, in accordance with a fourth embodiment of the present invention.

The fourth packet 401, also of a rigid type, has the shape of a substantially rectangular parallelepiped and extends along the fourth longitudinal axis Z4.

In particular, the fourth pack 401 belongs to the type of packs with beveled edges.

A fourth pack 401, made of, for example, hard cardboard, is configured to accommodate an ordered group of cigarettes wrapped in an inner wrapper 402, and includes a housing 403 that can hold cigarettes and a cover 404 that can be opened or closed, providing access to cigarettes.

The enclosing body 403 comprises a bottom wall 407 from which a rear wall 409 extends, the size of which, measured in a plane parallel to the fourth axis Z4, is larger than the size of the front wall 408 (Fig. 44).

Between the front wall 408 and the rear wall 409 are two side walls 410, each of which is smaller than the size of the front wall 408 and the rear wall 409.

The side walls 410 are essentially irregular hexagons and are connected to the back wall 409 by flat parts 413, or chamfers, which are relative to the rear wall 409 at an angle of, for example, essentially 135 °.

In particular, the side walls 410, the flat parts 413 and the rear wall 409 are bounded above by the upper U-shaped edge 409 '.

In accordance with one embodiment of the present invention (not shown), curved parts are provided instead of flat parts 413.

The closure body 404 includes a main body 492 connected, as will be described in detail below, to the host body 403, and a cover 496.

In particular, the main body 492, which interacts with the containing body 403 for holding smoking articles, is connected to the cover 496 by a hinge 405, and the cover 496 is movable between the open position (Figs. 41-44) and the closed position (Figs. 45 and 46 ) by turning around hinge 405.

In addition, the main body 492 is connected to the front wall 408 by another hinge 405 ', and the main body 492 is movable between the open position (Figs. 41-44) and the closed position (Figs. 45 and 46) by turning around the hinge 405' .

In particular, the hinge 405 and the other hinge 405 'are substantially parallel and are in the same plane.

The cover 496 comprises an upper side 414, which, when closed, is opposite the bottom wall 407.

The rear side 415 'is connected to the upper side 414, and the length of the rear side 415' when the fourth pack 401 is closed, measured in a plane parallel to the fourth axis Z4, is less than the length of the rear wall 409.

In particular, in the closed position of the fourth packet 401, the rear side 415 'is adjacent to the rear wall 409.

Two sides 416 extend from the rear side 415 '.

The sides 416 comprise corresponding expanded parts 453 having, for example, a substantially trapezoidal shape and adjacent to the upper side 414.

The sides 416 also contain corresponding elongated parts 454, or chamfers, for example, flat, located between the rear side 415 'and the expanded parts 453 and connecting the rear side 415' with the expanded parts 453.

The cover 496 also includes a front side 415 opposite the rear side 415 'and connecting the sides 416.

The main body 492 contains another front side 487, when the fourth pack 401 is closed, opposite the back wall 409.

A hinge 405 is formed between the other front side 487 and the front side 415, and a hinge 405 'is formed between the other front side 487 and the front wall 408.

From the opposite sides of the other front side 487, two other lateral sides 489 extend, having, for example, a substantially isosceles trapezoid shape.

In particular, the other sides 489 form a side profile 488 ′ that complements the side profile of the upper portion of the side walls 410.

The size of each of the other sides 489 is smaller than the size of the other front side 487.

In particular, each of the other sides 489 comprises, respectively, another elongated portion 486.

The other elongated portions 486 are flat and angled at approximately 90 ° with respect to the other front side 487.

Each of the other sides 489 also includes a fixing part 420 (FIG. 41) connected to a corresponding other elongated part 486 and attached, in particular glued, to the inner surface 419 of the other front side 487.

In accordance with one embodiment of the invention (not shown), the fixing parts 420 extend substantially along the entire length of the other front side 487.

The locking parts 420, having, for example, a trapezoidal shape, respectively comprise first edges 421 extending when the third pack 301 is closed, substantially parallel to the fourth axis Z4.

In particular, the first edges 421 are at some distance from each other, leaving the middle parts of the inner surface 419 free.

In accordance with one embodiment of the invention (not shown), the first edges 421 are adjacent to each other, as a result of which the locking parts 420 extend over substantially the entire width of the closure body 404.

Each of the other sides 489 comprises a stiffener 424 (FIG. 41), having, for example, a trapezoid shape.

The stiffening elements 424 are located between the respective other elongated portions 486 and the corresponding locking parts 420.

Also, the length of the stiffening elements 424, measured in a plane parallel to the fourth axis Z4, is substantially less than the length of the other elongated parts 486.

As already mentioned, the stiffening elements 424 connect the other elongated parts 486 with the fixing parts 420, the other elongated parts 486, the stiffening elements 424 and the inner surface 419 of the other front side 487 limit the corresponding longitudinal gaps 426, passing when the fourth pack 401 is closed, essentially parallel to the fourth axis Z4.

Thus, each of the other sides 489 is formed, at least in part, by the other outer elongated portion 486 and the inner stiffener 424.

The locking parts 420 may include print zones indicated by a dashed line, containing, for example, labels, images, or other information for the user.

According to one embodiment of the fourth pack 401 (not shown), the other elongated portions 486 are curved.

In this embodiment, gaps 426 are also limited by stiffeners 424, other elongated portions 486, and inner surface 419.

In another embodiment of the fourth bundle 401 (not shown), the other elongated portions 486 are flat and positioned at an angle of approximately 135 ° with respect to the other front side 487.

In this embodiment, the gaps 426 are also limited by stiffeners 424, other elongated portions 486, and an inner surface 419.

When the fourth packet 401 is in the closed position of FIGS. 45 and 46, the rear side 415 ′ of the lid 496 is flush with the rear wall 409 of the housing 403.

In particular, the lower edge 429 of the cover 496 complementary to the upper edge 409 ′ of the housing 403 is flush with the upper edge 409 ′.

When the fourth packet 401 is in the closed position, the sides 416 and other sides 489 are adjacent to the respective side walls 410 and are substantially in the same plane with them, and the side profile 488 ′ is flush with the other side profile 410 ′ of the upper part side walls 410.

In particular, the sides 416 and other sides 489 are adjacent.

The fourth pack 401 also contains an inner shell 406 located inside the enclosing body 403.

As already mentioned, the inner shell 406 accommodates a group of cigarettes wrapped in an inner wrapper 402 containing a sheet of styrene or metal foil. The inner wrapper 402 is a wrapper of a known type and has no significant differences compared to the inner wrappers used in conventional cigarette packs.

The inner shell 406 comprises a main wall 430 delimited by an upper contour 431 having, for example, a pointed U-shape.

In accordance with one embodiment of the invention (not shown), the main wall 430 comprises print areas indicated by a dashed line, containing, for example, labels, images, or other information for the user.

Two smaller walls 432 are connected to the main wall 430, and an auxiliary wall 498 extends from each of which, each of the auxiliary walls 498 contains a print zone indicated by a dashed line containing, for example, labels, images or other information for the user.

The smaller walls 432 laterally comprise an inner wrap 402, and the sub walls 498, opposite the main wall 430, are folded behind the inner wrap 402.

In particular, the auxiliary walls 498 comprise, respectively, other first edges 421 ′ extending with the closed position of the inner shell 406 substantially parallel to the fourth axis Z4, the other first edges 421 ′ being adjacent to each other.

In accordance with one embodiment of the invention (not shown), the other first edges 421 ′ are spaced apart, leaving the middle parts of the inner wrapper 402 free.

In addition, the auxiliary walls 498 form another upper contour 431 'having, for example, a pointed U-shape similar to that of the upper contour 431.

The inner shell 406 also contains two flat chamfers 433, for example, at an angle of approximately 135 ° with respect to the main wall 430, and connecting the main wall 430 with smaller walls 432.

From the chamfers 433 near the upper contour 431, two closing wings 497 protrude outwardly, which are adapted to engage with the cover 496 to hold it in the closed position.

The inner shell 406 also contains two other flat chamfers 433 ', for example, at an angle of approximately 135 ° with respect to the secondary walls 498, with each of the other flat chamfers 433' connecting the smaller wall 432 with the secondary wall 498.

The inner shell 406 also includes a bottom valve (not shown) connected to the main wall 430 and bounded by a perimeter complementing the upper circuit 431. The lower valve is folded under the inner wrap 402.

The inner shell 406 also contains two other lower valves (not shown), each of which is connected to a corresponding secondary wall 498.

In particular, other lower valves, as well as said lower valve, are folded under the inner wrap 402 so as to hold the latter from the bottom.

The inner shell 406 is located inside the enclosing body 403 and is attached to the side walls 410 and / or the rear wall 409 of the enclosing body 403.

In particular, one or more adhesive points may be applied to the inner surface of the back wall 409 and / or to the inner surfaces of the side walls 410, allowing the back wall 409 to be glued to the main wall 430 and / or side walls 410 to the corresponding smaller wall 432. This provides holding the closed position of the inner shell 406 around the inner wrapper 402.

The fourth pack 401 can also be used as a regular cigarette pack.

Thus, the user can open the fourth pack 401 by turning the lid 496 around the hinge 405 and remove the cigarette in the same way as with conventional packs.

After applying the adhesive, the preform 435 is folded inward in the usual sequence, since this preform does not contain additional panels compared to conventional preforms. Consequently, the preform 435 can be processed on a conventional hard cigarette pack making machine.

On Fig presents the inner frame 463, which can be used to form the inner shell 406.

The inner frame 463 may be made of cardboard, possibly connected to a metal sheet, such as aluminum.

The inner frame 463 can be formed directly on the packaging machine from rolled material cut with a knife having a shaped profile corresponding to the upper transverse profile 464 and the lower transverse profile 465 of the inner frame 463.

Two inner weakening lines 466, two outer weakening lines 467, two intermediate weakening lines 468 and two other intermediate weakening lines 468 'are also formed on the inner frame 463 by appropriate cutters.

In particular, intermediate attenuation lines 468 are located between the internal attenuation lines 466 and other intermediate attenuation lines 468 ', and the latter are located between the intermediate attenuation lines 468 and the external attenuation lines 467, and the external attenuation lines 467 are located outside of the internal attenuation lines 466.

Also in the lower part of the inner frame 463, a transverse attenuation line 469 is formed, extending transversely with respect to the inner, intermediate, and outer attenuation lines 466, 468, 468 ', and 467.

Another transverse attenuation line 490 extends laterally with respect to the inner, intermediate and outer attenuation lines 466, 468, 468 'and 467 at the bottom of the inner frame 463.

Between the inner weakening lines 466 and the transverse weakening line 469, a main panel 470 is formed for forming the main wall 430 of the inner shell 406.

On the sides of the main panel 470 there are two side panels 471, each of which is located between the inner attenuation line 466 and the intermediate attenuation line 468. Each of the side panels 471 is intended to form a chamfer 433 of the inner shell 406.

On the sides of the side panels 471 there are two intermediate panels 472, each of which is located between the intermediate attenuation line 468 and the other intermediate attenuation line 468 '.

Each of the intermediate panels 472 is designed to form a smaller wall 432 of the inner shell 406.

In addition, outside of the intermediate panels 472, there are two other side panels 471 ′, each of which is located between the other intermediate weakening line 468 ′ and the outer weakening line 467.

Each of the other side panels 471 ′ is intended to form another chamfer 433 ′ of the inner shell 406.

Also on the sides of the other side panels 471 ′ there are two external panels 473, each of which is connected to a respective other side panel 471 ′ along an external attenuation line 467.

Outer panels 473 are folded behind the inner wrap 402 to form auxiliary walls 498.

Thus, the inner frame 463 after folding surrounds the inner shell 406 on four sides.

Between the transverse weakening line 469 and the lower transverse profile 465, an end panel 474 is formed which can be folded under the inner wrap 402 to form a lower valve.

Also between the other transverse weakening line 490 and the lower transverse profile 465, other end panels 489 are formed which are capable of folding under the inner wrap 402 to obtain other lower valves.

In addition, the inner frame 463 contains two other C-shaped slots 488, designed to form the closing wings 497.

In the packaging process, the inner frame 463 is folded around the inner wrapper 402 and glued to it using glue points located in the same way as on conventional inner frames.

The inner frame 463 can be folded around the inner wrapper 402 using a folding unit, similar to that used for conventional inner frames.

Then, the containing body 403 and the closing body 404 are formed by folding the workpiece 435 around the inner shell 406.

From the foregoing, it is clear that the fourth pack 401 can also be made using conventional packaging machines, essentially no different from existing ones.

It should be noted that the closure body 104, 204, 304 and 404 of the packs 101, 101a-e, 201, 301 and 401 in accordance with the present invention is more durable than the closure body of the known packs.

In fact, the fixing parts 120, 220, 320 and 420, attached, in particular glued, to the inner surface 115, 219, 319 and 419 of the front side 115, 215, 315 and 415, contradict the trends of the side sides 116, 216, 389 and 489 to bend outward and, essentially, exclude such bending, while keeping the sides 116, 216, 389 and 489, essentially straight.

In addition, since the sides 116, 216, 389 and 489 are stiffer, the appearance of the packs 101, 101a-e, 201, 301 and 401 is improved, and the closure body 104, 204, 304 and 404 becomes easier to handle.

Also, since the sides 116, 216, 389 and 489 are stiffer than the sides of the known packs, this makes it possible to increase the size of the front side 115, 215, 315 and 415 compared to the known packs, thereby providing an increase in the surface accessible to posting messages to the consumer, such as advertisements, etc.

In particular, such messages can be pre-printed on the fixing parts 120, 220, 320 and 420, on the end part 118 and on the main walls 130, 230, 330, on the auxiliary walls 498.
