PACK FOR SMOKING ARTICLES

Description

TECHNICAL FIELD

[0001] The present invention relates to a cigarette pack containing a group of small-sized smoking articles.

[0002] The present invention is advantageously implemented in a pack of cigarettes to which explicit reference will be made in the following description without any consequent loss of generality.

[0003] In the present text, indeed, reference will be made in general to the specific example of "cigarettes" rather than to the more generic expression "smoking articles" without, however, relinquishing any generality with respect to other types of articles (such as cigars, cigarillos, cigarettes of an electronic type or e-cigarettes, auxiliary products such as filters, refills for e-cigarettes and other tobacco-based products or products based on alternative or substitute components for tobacco).

PRIOR ART

[0004] Rigid cigarette packs with a hinged lid are currently the most common packs for cigarettes on the market, since they are simple to produce, easy and practical to use and provide good mechanical protection for the cigarettes contained within. A rigid pack of cigarettes with a hinged lid comprises a group of cigarettes wrapped in a wrapper of metallized paper in order to form an inner wrap and a rigid outer container that houses the inner wrap; the outer container is cup-shaped, has an open upper end and is provided with a lid, which is also cup-shaped and is hinged to the container along a hinge so as to rotate, relative to said container, between an open position and a closed position of the open end. A collar is normally provided, which is folded and attached inside the container so as to partially project out of the open end and engage a corresponding inner surface of the lid when the lid is arranged in the closed position.

[0005] Typically, in packets that accommodate a group of cigarettes that is smaller relative to the internal volume of the outer container in terms of width and height, a filling element is inserted to make up for the difference in size between the group of cigarettes and said outer container. For instance, such a filling element is described, respectively, in the patent applications WO2016005949A1 and WO2018203287A1. In these disclosures, the filling element is inserted in the outer container and has a front wall which is arranged in contact with the inner wrap, a rear wall which is parallel to and opposite the front wall, an upper wall which is perpendicular to the front wall, and two side walls which are opposite one another, are perpendicular to the front wall and to the upper wall and rest against the side walls of the outer container. However, the filling element described in WO2016005949A1 and WO2018203287A1 has a plurality of disadvantages. The main disadvantage of both is that the filling element is not rigid enough to maintain the correct position throughout the use of the cigarette pack. In WO2016005949A1, the lower portion of the front wall of the filling element is accordingly not able to adequately support the group of cigarettes accommodated within, inasmuch as it tends to bend toward the rear wall of said filling element, as it does not provide an adequate resistance to the pressure exerted by the group of cigarettes on the same. In WO2018203287A1, on the other hand, the rear wall of the filling element simply rests against two pairs of supporting wings which are obtained in the side walls and in the front wall and folded toward the rear wall. However, the two pairs of supporting wings tend to not maintain the correct position throughout the use of the cigarette pack. Consequently, without the proper support of the supporting wings, the rear wall does not maintain its position in contact with the rear wall of the cup-shaped body. Moreover, in both patent applications, the filling element tends to collapse onto itself so that the group of cigarettes ends up moving around inside the outer container.

DESCRIPTION OF THE INVENTION

[0006] The object of the present invention is to provide a cigarette pack containing a group of small-sized smoking articles which does not possess the drawbacks of the state of the art and which is easy and economical to produce.

[0007] In accordance with the present invention, a pack is provided as claimed in the attached claims.

PREFERRED EMBODIMENTS OF THE INVENTION

[0009] In Figures 1-5, the number 1 indicates a rigid cigarette pack as a whole. The cigarette pack 1 comprises a rigid outer container 2 (namely made of cardboard or rigid paperboard), which is cup-shaped, has an open upper end 3 (visible in Figures 3 and 4) and is provided with a lid 4. The lid 4 is cup-shaped and is hinged to the outer container 2 along a hinge 5 (illustrated in Figure 2) so as to rotate, relative to said outer container 2, between an open position (illustrated in Figures 3 and 4) and a closed position (illustrated in Figures 1 and 2).

[0010] The outer container 2 has a substantially rectangular parallelepipedal shape oriented in a predominantly vertical direction of development, is cup-shaped and has the open upper end 3, a lower wall 6 opposite the open upper end 3, a front wall 7 and a rear wall 8 (in which the hinge 5 is arranged) which are parallel to and opposite one another, and two side walls 9 which are parallel to and opposite one another. Four longitudinal corners are defined between the front wall 7, the rear wall 8 and the side walls 9 of the outer container 2, while four transverse corners are defined between the walls 7, 8 and 9 and the lower wall 6 of the outer container 2.

[0011] The lid 4 has a substantially rectangular parallelepipedal shape, is cup-shaped and has an open lower end (facing the open upper end 3 of the outer container 2 when the lid 4 is in the closed position), an upper wall 10 (which is parallel to and opposite the lower wall 6 of the outer container 2 when the lid 4 is in the closed position), a front wall 11 (which is parallel to and aligned with the front wall 7 of the outer container 2 when the lid 4 is in the closed position), a rear wall 12 (which is parallel to and aligned with the rear wall 8 of the outer container 2 when the lid 4 is in the closed position and is hinged to the rear wall 8 of the outer container 2 along the hinge 5) and two side walls 13 parallel to and opposite one another (which are parallel to and aligned with, in particular co-planar with and adjacent to, the side walls 9 of the outer container 2 when the lid 4 is in the closed position). Four longitudinal corners are defined between the front wall 11, the rear wall 12 and the side walls 13 of the lid 4, while four transverse corners are defined between the walls 11, 12 and 13 and the upper wall 10 of the lid 4. The longitudinal corners and the transverse corners of the lid 4 are parallel to and aligned with the corresponding longitudinal and transverse corners of the outer container 2 when the lid 4 is in the closed position.

[0012] As illustrated in Figures 3 and 4, the cigarette pack 1 further comprises a rigid collar 14, which is folded into a "U" shape and attached (by gluing) inside the outer container 2 so as to partially project out of the open upper end 3 of the outer container 2 and engage a corresponding inner surface of the lid 4 when said lid 4 is arranged in the closed position. The collar 14 comprises a front wall 15, which is attached to the front wall 7 of the outer container 2 and is arranged in contact with the front wall 11 of the lid 4 when the lid 4 is in the closed position, and two side walls 16, which are attached to the side walls 9 of the outer container 2 and are arranged in contact with the side walls 13 of the lid 4 when the lid 4 is in the closed position.

[0013] The front wall 15 of the collar 14 is provided with an extraction opening 20 (illustrated in Figures 3 and 4) through which access to the contents of the pack 1 of cigarettes is facilitated.

[0014] According to the embodiment illustrated in the attached Figures 3 and 4, the front wall 15 of the collar 14 is provided with a pair 17 of flaps which protrude laterally so as to engage the side walls 13 of the lid 4 by interference when the latter is in the closed position so as to keep the lid 4 in the closed position.

[0015] According to a different embodiment, not illustrated, the front wall 15 of the collar 14 has no pair of flaps 17.

[0016] As illustrated in Figures 7 and 8, the pack 1 of cigarettes comprises an inner wrap 18 which is arranged (accommodated) in the outer container 2 so as to partially project out of the open upper end 3 and encloses a group 19 of cigarettes. In the embodiment illustrated in the attached figures, the inner wrap 18 is of a traditional type (i.e. not sealed) and has a removable pull-out upper portion which must be removed when the pack 1 of cigarettes is first opened in order to gain access to the cigarettes. According to an alternative embodiment, the inner wrap 18 is of the sealed type and has an extraction opening engaged by a reusable closing label (i.e. provided with a repositionable glue).

[0017] In particular, as illustrated in Figures 3-8, the inner wrap 18 housed in the outer container 2 has a smaller width than a width of the outer container 2 (Figure 5). In other words, the term width indicates a dimension measured transversely relative to the direction of longitudinal extension of the pack 1 of cigarettes and parallel to the side walls 9 of the outer container 2. Consequently, in order to make up for the difference in width between the outer container 2 and the inner wrap 18, a filling element 21 is arranged in said outer container 2. The filling element 21 is completely independent of the collar 14. In other words, the collar 14 and the filling element 21 are not formed from a single element.

[0018] The filling element 21 has a front wall 22, which is arranged in contact with the inner wrap 18, an upper wall 23, which is perpendicular to the front wall 22, and two side walls 24, which are opposite one another, are perpendicular to the front wall 22 and to the upper wall 23 and rest against the side walls 9 of the outer container 2. Figure 6 illustrates the arrangement of the collar 14 relative to the filling element 21. In particular, parts of the filling element 21 which are not in view in the figure are indicated by the dashed line. As illustrated in Figure 6, the side walls 24 of the filling element 21 rest against the side walls 16 of the collar 14 which, in turn, are in contact with the respective side walls 9 of the outer container 2. In particular, the side walls 16 of the collar 14 are glued to the side walls 24 of the filling element 21. Advantageously, the filling element 21 also comprises a rear wall 25 parallel to and opposite the front wall 22 and which has a smaller longitudinal dimension (i.e. the dimension measured parallel to the longitudinal extension of the filling element 21) relative to the front wall 22 of the filling element 21.

[0019] As illustrated in Figures 9 and 11-13, the side walls 24 of the filling element 21 have a greater longitudinal extension relative to the front wall 22. In other words, the side walls 24 continue (i.e. project out) beyond the front wall 22 at the bottom. According to an alternative embodiment, illustrated, for instance, in Figure 10, at least one end portion 26 of the protruding side walls 24 is folded by 90° so that that portion is arranged parallel to the lower wall 6 of the outer container 2. In other words, according to this embodiment, the end portion 26 of each side wall 24 of the filling element 21 is folded substantially by 90° relative to said side wall 24 and is placed in contact with the lower wall 6. According to a possible embodiment, the folded end portion 26 is glued to the lower wall 6 of the outer container 2; alternatively, the folded end portion 26 rests (i.e. without gluing) against the lower wall 6 of the outer container 2.

[0020] As illustrated in the attached figures, the filling element 21 comprises two support members 27, each arranged in contact with the rear wall 8 of the outer container 2 and consisting of a panel 28 and of a panel 29 which are hinged to one another along a (preferably pre-weakened) central folding line 30 defining a, in particular longitudinal, corner 31 of the support member 27. Each panel 28 is hinged at one end to the corresponding panel 29 along the central folding line 30 and hinged at the opposite end to the front wall 22 (in particular along a, preferably pre-weakened, side folding line 32). Each panel 29, on the other hand, is hinged at one end to the corresponding panel 28 along the central folding line 30 and hinged at the opposite end to a corresponding side wall 24 (in particular along a further, preferably pre-weakened, side folding line 32). In other words, the support member 27 is substantially formed in the shape of a "V" and comprises the two panels 28 and 29 which are separated by the central folding line 30 and which are respectively hinged to the front wall 22 or to the corresponding side wall 24 along the respective side folding line 32. In particular, as illustrated in the figures, the folding lines 30 and 32 preferably extend parallel to the direction of longitudinal extension of the filling element 21. According to an alternative embodiment, not illustrated, at least one of the folding lines 30 and/or 32 extends transversely (i.e. at an incline) relative to the direction of longitudinal extension of the filling element 21.

[0021] As illustrated in Figures 15-19, each support member 27 is delimited longitudinally by two cutting lines 33 which are made partly in the front wall 22 of the filling element 21 and partly in the corresponding side wall 24 of the filling element 21. In other words, each support member 27 is delimited along a longitudinal direction, which is substantially parallel to the side walls 9, by the cutting lines 33 which are made partly in the front wall 22 of the filling element 21 and partly in the corresponding side wall 24 of the filling element 21. Further, each support member 27 is delimited transversely by the two side folding lines 32 which are arranged longitudinally, are parallel to the central folding line 30, are arranged on opposite sides of said central folding line 30 and extend between the two cutting lines 33. In other words, each support member 27 is delimited along a transverse direction, which is substantially parallel to the lower wall 6, by the two side folding lines 32 which are arranged longitudinally, are parallel to the central folding line 30, are arranged on opposite sides of said central folding line 30 and extend between the two cutting lines 33.

[0022] According to a possible embodiment, not illustrated, both the cutting line 33A closer to the upper wall 23 of the filling element 21 and the cutting line 33B farther from the upper wall 23 of the filling element 21 are straight.

[0023] According to the possible embodiment illustrated in Figure 15, the cutting line 33A which is closer to the upper wall 23 of the filling element 21 is straight, while the cutting line 33B which is farther from the upper wall 23 of the filling element 21 is a broken line.

[0024] According to a further possible embodiment, illustrated, for instance, in Figures 16-19, both the cutting line 33A closer to the upper wall 23 of the filling element 21 and the cutting line 33B farther from the upper wall 23 of the filling element 21 are broken lines.

[0025] In particular, as illustrated in the attached figures, the support members 27 are separated from one another by at least one partition 34 which is part of the front wall 22 of the filling element 21. In other words, in order to guarantee the required stability and rigidity of the support members 27, at least one partition 34 is arranged between the latter.

[0026] According to the illustration shown in Figures 9, 10 and 13, the support members 27 are respectively separated by a single partition 34. According to the illustration shown in Figures 11 and 12, the support members 27 are respectively separated by two partitions 34 which are aligned longitudinally.

[0027] The partition 34 is delimited laterally by the two side folding lines 32 of the support members 27.

[0028] According to the embodiment illustrated in Figures 9-13, each support member 27 has the panel 28 which forms an acute angle α with the front wall 22 of the filling element 21. In particular, the acute angle α ranges from 30 to 50°. The panel 29, on the other hand, forms an obtuse angle β with the corresponding side wall 24 of the filling element 21. In particular, the obtuse angle β ranges from 95 to 120°.

[0029] As illustrated in Figure 9, each support member 27 forms a quadrilateral, in particular a convex quadrilateral, at the cutting lines 33. In other words, at the cutting lines 33, the transverse end of the panel 28, the transverse end of the panel 29, a portion of the side wall 24 of the filling element 21 and a portion of the front wall 22 of the filling element 21 define the quadrilateral. Due to its shape, the thus delimited convex quadrilateral renders possible the realization of an improved support of the group 19 of cigarettes, as the corner 31 is able to rest against the rear wall 8 of the outer container 2. Moreover, the corner 31 also supports the rear wall 25 of the filling element 21 and is arranged against the same.

[0030] According to the illustration shown in particular in Figures 9-13, at least one support member 27 comprises at least one supporting wing 35, which prolongs the panel 29 beyond the central folding line 30, is arranged in contact with the rear wall 8 of the outer container 2 and is obtained by making, on the panel 28, a cutting line 36, which is "U"-shaped and extends from the central folding line 30. When the supporting wing 35 is in contact with the rear wall 8 of the outer container 2, it bends so as to adopt a co-planar position relative to the rear wall 8. In other words, the thus shaped supporting wing 35 is deformable in a manner such that it adopts a position in contact with or without a connection to the rear wall 8.

[0031] According to a possible embodiment, the supporting wing 35 is arranged in contact, without a connection, to the rear wall 8 of the outer container 2. Alternatively, the supporting wing 35 is attached, preferably glued, to the rear wall 8 of the outer container 2, further increasing the stability of the filling element 21. The supporting wing 35 can have different dimensions and geometries (as, for instance, illustrated in the embodiments shown in Figures 9-13) to increase the contact surface between the supporting wing 35 of each support member 27 and the rear wall 8 so as to increase its deformation and thus its flexion.

[0032] According to a possible embodiment, not illustrated, at least one support member 27 comprises at least one supporting wing 35, which prolongs the panel 28 beyond the central folding line 30, is arranged in contact with the rear wall 8 of the outer container 2 and is obtained by making, on the panel 29, a cutting line 36, which is "U"-shaped and extends from the central folding line 30. In other words, the supporting wing 35 is formed as an extension of the panel 28 or of the panel 29. Accordingly, according to this embodiment, the supporting wing 35 has an opposite orientation relative to the one illustrated in Figures 9-13.

[0033] According to the illustration shown in Figures 9, 10 and 12, each support member 27 has at least one supporting wing 35 of its own and the supporting wings 35 of the two support members 27 are transversely aligned with one another. In other words, the two supporting wings 35 are arranged at the same distance from the upper wall 23. Moreover, in this case, the two supporting wings 35 can overlap one another or not.

[0034] Alternatively, according to the illustration shown in Figure 13, each support member 27 has at least one supporting wing 35 of its own and the supporting wings 35 of the two support members 27 are not transversely aligned with one another. In other words, the two supporting wings 35 are arranged at two different distances from the upper wall 23.

[0035] As indicated in Figures 9, 10 and 12, the support members 27 have an identical number of supporting wings 35. Alternatively, as illustrated in Figures 11 and 13, the support members 27 have a different number of supporting wings 35. In particular, as illustrated in Figure 11, a support member 27 has a single supporting wing 35, while the other support member 27 has no supporting wing 35. In this case, the single supporting wing can extend between the two central folding lines 30 of the two support members 27. Alternatively, as illustrated in Figure 13, one support member 27 has a single supporting wing 35, while the other support member 27 has two supporting wings 35. In other words, one support member 27 has two supporting wings 35 and the other support member 27 has a single supporting wing 35 arranged between the two supporting wings 35 of the other support member 27.

[0036] According to the embodiment illustrated in Figures 11 and 12, the supporting wing 35 of one support member 27 extends up to the other support member 27. According to the embodiment illustrated in Figures 9-12, the front wall 22 of the filling element 21 has a straight lower edge 37.

[0037] Alternatively, as illustrated in Figure 13, the front wall 22 of the filling element 21 has a lower edge 37 formed in the shape of a circumferential arc.

[0038] As illustrated in Figure 15, the outer container 2 and the lid 4 are formed by folding a rigid blank 38 of a conventional type provided with a plurality of (pre-weakened) folding lines 39 and 40. The blank 38 comprises two (pre-weakened) longitudinal folding lines 39 and a plurality of (pre-weakened) transverse folding lines 40 which define, between the two longitudinal folding lines 39, a panel 7' which constitutes the front wall 7 of the outer container 2, a panel 6' which constitutes the lower wall 6 of the outer container 2, a panel 8' which constitutes the rear wall 8 of the outer container 2, a panel 12' which constitutes the rear wall 12 of the lid 4, a panel 10' which constitutes the upper wall 10 of the lid 4, a panel 11' which constitutes the front wall 11 of the lid 4, and a reinforcement flap 11". The reinforcement flap 11" is attached to the front wall 11 of the lid 4 along a transverse folding line 40, is folded by 180° (into the cigarette pack 1) relative to the front wall 11 of the lid 4 (i.e. relative to the panel 11') and is placed and glued against an inner surface of the front wall 11 of the lid 4 (i.e. against the panel 11'). The blank 38 comprises a pair of wings 9', which are arranged on opposite sides of the panel 7', are attached to the panel 7' along the two longitudinal folding lines 39 and constitute a part of the side walls 9 of the outer container 2. The blank 38 comprises a pair of wings 9", which are arranged on opposite sides of the panel 8', are attached to the panel 8' along the two longitudinal folding lines 39, constitute a part of the side walls 9 of the outer container 2 and are placed in an overlapping arrangement and glued to the corresponding wings 9' so as to constitute the side walls 9 of the outer container 2.

[0039] The blank 38 comprises a pair of wings 13', which are arranged on opposite sides of the panel 11', are attached to the panel 11' along the two longitudinal folding lines 39 and constitute a part of the side walls 13 of the lid 4. The blank 38 comprises a pair of wings 13", which are arranged on opposite sides of the panel 12', are attached to the panel 12' along the two longitudinal folding lines 39, constitute a part of the side walls 13 of the lid 4 and are placed in an overlapping arrangement and glued to the corresponding wings 13' so as to constitute the side walls 13 of the lid 4.

[0040] The blank 38 comprises two tabs 41, which are attached to the wings 9" along a transverse folding line 40, folded by 90° and placed against an inner surface of the panel 6'.

[0041] The blank 38 comprises two tabs 42, which are attached to the wings 13" along a transverse folding line 40, folded by 90° and placed against an inner surface of the panel 10'.

[0042] According to the illustration shown in Figure 14, the collar 14 is formed by folding a rigid blank 43 of a conventional type provided with two (pre-weakened) longitudinal folding lines 44. The blank 43 comprises a panel 15', which constitutes the front wall 15 of the collar 14, and two panels 16', which respectively constitute the side walls 16 of the collar 14 and which are adjacent to the panel 15'. The panel 15' and the adjacent panels 16' are separated by the longitudinal folding lines 44.

[0043] According to the illustration shown in Figures 16-21, the filling element 21 is formed by folding a rigid blank 45 provided with a plurality of (pre-weakened) folding lines 46 and 47 defining a substantially hollow internal volume 48. The blank 45 comprises two (pre-weakened) longitudinal folding lines 46 and a plurality of (pre-weakened) transverse folding lines 47 which define, between the two longitudinal folding lines 46, a panel 22' which constitutes the front wall 22 of the filling element 21, a panel 23' which constitutes the upper wall 23 of the filling element 21, and a panel 25' which constitutes the rear wall 25 of the filling element 21. The blank 45 also comprises two panels 24', which respectively constitute the side wall 24 of the filling element 21 and are arranged on opposite sides of the panels 22' and 23'. The blank 45 comprises two tabs 49, which are attached to the respective panel 24' along a transverse folding line 47, folded by 90° and placed against an inner surface of the panel 23'.

[0044] The blank 45 further comprises the panels 28 and 29, which constitute the support member 27. The panels 28 and 29 are separated from one another by the respective central folding lines 30. The panels 28 and 29 are further separated from the panels 22' or 24' by means of the respective side folding lines 32. Moreover, the supporting wings 35 are separated from the panel 28 by the cutting line 36, which exhibits a substantially "C" shape, so that they project out of the support member 27.

[0045] The blank 45 illustrated in Figure 18 further comprises the two panels 26', which constitute the end portion 26 of the side walls 24, which are adjacent to the respective panels 24', are separated from the same by a (pre-weakened) transverse folding line 47 and which are folded by 90° relative to the side wall 24. Advantageously, the end portion 26 is folded into the filling elements 21 which have support members 27 that are larger in size.

[0046] In the embodiments illustrated in the attached figures, the longitudinal and transverse corners are straight; alternatively, the longitudinal and/or transverse corners may be rounded or bevelled.

[0047] Moreover, in the embodiments illustrated in the attached figures, the cigarette pack 1 is of the type with a hinged lid 4 and, consequently, the filling element 21 is positioned between the rear wall 8 of the outer container 2 and the inner wrap 18. According to alternative embodiments, the cigarette pack 1 is of a different type, for instance comprising a sliding opening. In packs of a different type, the filling element 21 may be placed between the front wall 7 of the outer container 2 and the inner wrap 18.

[0048] The cigarette pack 1 described in the foregoing has numerous advantages.

[0049] First of all, the cigarette pack 1 exhibits greater stability inasmuch as said filling element 21 is stabler and renders possible an improved support of the inner wrap 18. In particular, the support members 27 increase the rigidity and thus the stability of the filling element 21, facilitating a support for the inner wrap 18 along the entire front wall 22 of the filling element 21 and avoiding, consequently, the undesired flexion of the front wall 22 of the filling element 21.

[0050] The internal volume 48 is substantially closed off from the outside (i.e. the inside of the filling element is not visible when the lid 4 is in the open position - Figure 3 - and the group 19 of cigarettes is inserted in the outer container 2), inasmuch as the rear wall 25 rests against the rear wall 8 of the outer container 2, thus preventing the upper wall 23 from rising, and consequently prevents access to the internal volume 48.

[0051] Moreover, the filling element 21 is more reliable compared with filling elements 21 of known types, as it can be glued to the inside of the outer container 2, thus preventing the filling element 21 from slipping out of the outer container 2.

[0052] The blank 45 allows a realization of the filling element 21 without the production of any scrap material. Indeed, the panel 25', which constitutes the rear wall 25 of the filling element 21, has a shape that is complementary to the shape of the lower edge 37 of the front wall 2 and of the lower end of the side walls 24.

[0053] Finally, the cigarette pack 1 described above can be produced in a packaging machine not too dissimilar from a standard packaging machine for rigid cigarette packs with a hinged lid; consequently, the costs involved in setting up a packaging machine for producing the cigarette pack 1 described above are not particularly high.
