DETAILED DESCRIPTION OF FORMS OF EMBODIMENT

[0062] We shall now refer in detail to the various forms of embodiment of the present invention, of which one or more examples are shown in the attached drawing. Each example is supplied by way of illustration of the invention and shall not be understood as a limitation thereof. For example, the characteristics shown or described insomuch as they are part of one form of embodiment can be adopted on, or in association with, other forms of embodiment to produce another form of embodiment. It is understood that the present invention shall include all such modifications and variants.

[0063] FIGS. 1-11, 15a-15d, 16a-16c, 17a-17c are used to describe forms of embodiment of a packet 10 for smoking articles, for example cigarettes, cigars or similar or equivalent, of the type with a hinged lid and sliding aperture (hinged-lid, slide-open packet).

[0064] In possible implementations, the packet 10 can have a rectangular parallelepiped shape, that extends along a longitudinal axis X. The edges of the packet 10 can be squared, or rounded or beveled.

[0065] In accordance with the present description, the packet 10 is a rigid packet which includes an internal shell 16 (see FIGS. 7 and 8 for example) and an external shell 11 (see FIG. 9 for example).

[0066] Typically the internal shell 16 can contain a group of organized smoking articles, generally wrapped in a wrapper 13 (see FIGS. 3, 18a, 18b for example). The wrapper 13 is able to house the group of organized smoking articles and is conformed to be inserted inside the external shell 11.

[0067] The external shell 11 is provided with an access aperture, which is typically delimited by a peripheral edge, or aperture edge. It is possible to access the smoking articles contained in the internal shell 16 through this aperture.

[0068] The internal shell 16 can be a collar, in particular a rigid collar. The collar can surround the wrapper 13. In particular, as is clear, the collar can surround the wrapper 13, wrapping it closely, so as to render the collar integral with the wrapper 13. Typically the wrapper 13 can be integrated with the internal shell 16, using adhesive or glue for example. For example, the union between the collar and the wrapper 13 can be obtained using a common adhesive located between the contact walls respectively of the collar and the internal wrapper. In possible implementations, the collar can be open at the top and bottom and can enclose on three sides or on four sides the group of organized smoking articles, wrapped in the wrapper 13. Furthermore, the collar can be open at the top and closed at the bottom and can therefore enclose on five sides the group of organized smoking articles, wrapped in the wrapper 13.

[0069] In accordance with the present description, the external shell 11 includes an external containing body 14. The external containing body 14 has said access aperture delimited by a peripheral edge. Moreover, in accordance with the present description, the external shell 11 includes a closing lid 12 and a connection tongue 20, configured to connect the closing lid 12 to the external containing body 14. In particular, the connection tongue 20 can be provided with a proximal connection end 20a connected to the closing lid 12. For example, the proximal connection end 20a can be connected to an edge of the closing lid 12. Moreover, the connection tongue 20 can be provided with a distal connection end 20b connected to the external connection body 14, in particular to said peripheral edge that delimits the access aperture of the external shell 11 (see FIGS. 2, 6, 9, 10, 11, 13, 15c, 15d, 16c, 17b, 17c for example).

[0070] In possible implementations, the closing lid 12 is connected to the external closing body 14 by means of the connection tongue 20, that can be configured to define a double-jointed articulated connection of the closing lid 12 to the external connection body 14, see FIGS. 6, 9 and 11 for example.

[0071] The closing lid 12 is hinged to the internal shell 16, and is thus able to rotate around a hinge or hinging line 15 (see FIGS. 2, 7, 8, 10, 11, 12, 13, 15a, 15c, 15d, 16c for example). The hinge or hinging line 15 can be provided on the internal shell 16.

[0072] In particular, the hinge 15 by means of which the closing lid 12 is hinged to the internal shell 16 defines a lid hinging axis Y around which the closing lid 12 can rotate.

[0073] This rotatable configuration around the hinge 15 allows to rotate the closing lid 12 between a closed condition (see FIGS. 1 and 2 for example) and an open condition (see FIGS. 3, 4, 15a-15d, 17b for example), in order to respectively close the access aperture and prevent access to the smoking articles contained in the internal shell 16 or to allow access to the smoking articles. In the closed condition, the closing lid 12 can typically abut against the peripheral edge that delimits the access aperture of the external shell 11, in particular of the external containing body 14. Moreover, in the closed condition of the closing lid 12, the internal shell 16 together with the wrapper 13 are housed completely inside the external shell 11.

[0074] In accordance with possible forms of embodiment described here, the external containing body 14, the closing lid 12 and the connection tongue 20 that form the external shell 11 can constitute a single body in continuous material from which they are made, and are therefore obtained from a single blank 80, suitably shaped and folded, as explained in detail hereafter (see FIGS. 14 and 20 for example).

[0075] Moreover, in accordance with the present description, the internal shell 16 is configured to slide, with respect to the external containing body 14, between a closed configuration (see FIGS. 1 and 2 for example), in which the internal shell 16 is completely inserted inside the external shell 11, and an open and extracted configuration (see FIGS. 5, 6, 15a-15d, 17a-17c for example), in which the internal shell 16 is partly extracted from the external shell 11, in particular from the external containing body 14. In other words, the packet 10 that includes the internal shell 16 that slides with respect to the external shell 11 is the slide-open type.

[0076] Moreover, the fact that the closing lid 12 is connected to the internal shell 16 by the hinge 15, as described above, prevents the internal shell 16 from being accidentally extracted completely from the external shell 11, in particular from the external containing body 14. Consequently, in possible implementations, the hinge 15 acts as a stopping or holding element to prevent the internal shell 16 from exiting completely from the external shell 11. In this way, it is not necessary to provide additional stopping and holding elements, thus avoiding further work that would increase times, complexity and costs of production.

[0077] In some forms of embodiment, the hinge or hinging line 15 can be in correspondence to the distal connection end 20b of the connection tongue 20 when the closing lid 12 is in its closed condition (see FIG. 2 for example).

[0078] Moreover, in some forms of embodiment, the hinge or hinging line 15 can surpass the proximal connection end 20a of the connection tongue 20, thus distancing itself from the distal connection end 20b of the connection tongue 20, when the closing lid 12 is in its open condition (see FIGS. 15c, 15d for example). Advantageously, therefore, the wrapper 13 together with the internal shell 16 can be driven slidingly inside the external containing body 14 operating directly on the closing lid 12. Functional apertures are thus not needed on the external shell 11, in particular on the external containing body 14, or on the closing lid 12 or on the connection tongue 20, in order to actuate this sliding extraction movement.

[0079] In practice, when the user opens the closing lid 12 in order to access the group of smoking articles, with a simple pulling operation he/she can also lift the internal shell 16, to which the closing lid 12 is hinged, together with the wrapper 13, so as to make visible the external walls of the internal shell 16 that protrude with respect to the peripheral edge that defines the access aperture of the external shell 11. The presence of the connection tongue 20 is functional to prevent the wrapper 13, wrapped by the internal shell 16, from exiting completely from the external containing body 14. In other words, the connection tongue 20 has an end-of-travel function for the sliding of the wrapper 13 wrapped by the internal shell 16 with respect to the external containing body 14. In this way the separation of the wrapper 13 wrapped by the internal shell 16 and the external containing body 14 is prevented.

[0080] Therefore, in accordance with the present description, the external shell 11, and in particular the external containing body 14, the closing lid 12 and the connection tongue 20 that form the external shell 11, has no other functional apertures, fissures, windows or other similar passages which can be used by a consumer to push the internal shell 16 to extract it from the external shell 11; that is, they have no other functional apertures able to put the internal shell 16 in the open and extracted configuration. Indeed, to this purpose, as we said, it is enough to operate a traction on the closing lid 12, that is always located outside the packet 10 and therefore easily accessible, rotating it around the hinge 15, which closing lid 12 therefore pulls with it, to the outside, the internal shell 16 to which it is connected, extracting it as desired.

[0081] In this way, in particular in the closed configuration (FIGS. 1 and 2) or in the configuration where the closing lid 12 is open but the internal shell 16 is not extracted (FIGS. 3 and 4), the external shell 11 has an aesthetic conformation which is totally traditional and acceptable even to conservative smokers, but at the same time it can be converted into a more modern and original packet, and therefore used with satisfaction even by innovative smokers, thanks to its slide-open configuration.

[0082] In accordance with forms of embodiment described here using FIGS. 18a and 18b, and combinable with all the forms of embodiment described here, the wrapper 13 that wraps the group of smoking articles can comprise a base wall 131, from which a front wall 132 and a rear wall 133, opposite the front wall 132, develop. Between the front wall 132 and the rear wall 133 two lateral walls 134 are interposed, which join the front wall 132 and the rear wall 133.

[0083] In accordance with possible forms of embodiment, described using FIGS. 7, 8, 17a, 17b, 18a, 18b for example, and combinable with all the forms of embodiment described here, the internal shell 16 can be a parallelepiped shape with a rectangular cross section, shaped as a cup for example, and can include a front wall 32, a rear wall 34, two parallel lateral walls 38 and can have at the upper part an opening upper end 40. The internal shell 16 can be open at the lower part, or be closed and therefore have a base wall 36. If the internal shell 16 has a base wall 36, this can therefore be conformed as a cup.

[0084] Therefore, with regard to with the internal shell 16, four longitudinal edges can be defined between the front wall 32, rear wall 34, and lateral walls 38, and four lower transverse edges between front wall 32, rear wall 34, lateral walls 38 and the base wall 36.

[0085] In possible implementations, the internal shell 16 can also have a removal window 39 (see FIGS. 3 and 5 for example) through which the smoking articles are removed. The removal window 39 can facilitate, for example, at least initially, the removal of the smoking articles by the consumer. The removal window 39 can be provided as a shaped aperture, of an essentially concave shape, typically with an open profile, in the upper part of the front wall 32. The removal window 39 can be defined, for example, by an upper cut on the internal shell 16, to facilitate access to the smoking articles contained in the wrapper 13. The upper cut can be U-shaped and protrude from the peripheral edge of the access aperture of the external containing body 14 even when the internal shell 16 together with the wrapper 13 are entirely housed in the external containing body 14. By the expression entirely housed we mean when the closing lid 12 is in the closed condition and generally the base wall 131 of the wrapper 13, enclosed by the internal shell 16, contacts a base wall 46 of the external containing body 14, or the base wall 36 of the internal shell 16, if provided, contacts the base wall 46 of the external containing body 14.

[0086] In accordance with possible forms of embodiment described using FIG. 9 for example, and combinable with all the forms of embodiment described here, the external containing body 14 can be essentially of a parallelepiped shape with rectangular cross section, shaped like a cup for example, and can include a front wall 42, a rear wall 44, said base wall 46, two parallel lateral walls 48. The front wall 42 can have a smaller extension than the rear wall 44. The distal connection end 20b of the connection tongue 20 can be attached to the rear wall 44 of the external containing body 14. Moreover the connection tongue 20 can be positioned essentially centrally between the lateral walls 48 of the external containing body 14. The external containing body 14 can also have an opening upper end 50, in this case delimited by a peripheral edge 49 (see FIGS. 3 and 5 for example). The opening upper end 50 delimited by the peripheral edge 49 defines the access aperture of the external shell 11. In the closed condition, the closing lid 12 can therefore abut against the peripheral edge 49 of the external containing body 14. Moreover, the base wall 46 of the external containing body 14 defines a base wall of the external shell 11.

[0087] Therefore, with regard to the external containing body 14, four longitudinal edges can be defined between front wall 42, rear wall 44 and lateral walls 48, and four lower transverse edges between front wall 42, rear wall 44, lateral walls 48 and base wall 46.

[0088] In accordance with possible forms of embodiment, with reference to FIG. 9 for example, the closing lid 12 can be cup shaped, and can include an upper wall 51, that in the closed condition is parallel to the base wall 46 of the external containing body 14, a front wall 52, a rear wall 54, connected to the rear wall 34 of the internal shell 16, two parallel lateral walls 58, and an opening lower end 60, that can be delimited by a peripheral edge 61. The upper wall 51 of the closing lid 12 defines an upper wall of the external shell 11. The front wall 52 of the closing lid 12 can have a longer extension than the rear wall 54 of the closing lid 12. The longer extension can be equal to the difference between the extension of the rear wall 44 of the external containing body 14 and the front wall 42 of the external containing body 14. Moreover, it can be provided that the proximal connection end 20a of the connection tongue 20 is attached to an edge that divides the upper wall 51 of the closing lid 12 from the rear wall 54 of the closing lid 12.

[0089] In particular the closing lid 12 can be a box-like lid, that is, it can include walls 52, 58, 54 that are perpendicular one consecutively to the other, that is, wall 52 is orthogonal to wall 58, which in its turn is orthogonal to wall 54, consequently parallel to wall 52, so as to give a box-like shape to the closing lid 12.

[0090] According to forms of embodiment described here, the front wall 42 of the external containing body 14 and the front wall 52 of the closing lid 12 form overall a front wall 62 of the external shell 11 (see FIG. 1 for example).

[0091] In accordance with the present description, and with reference to the front wall 42 and the front wall 62, by the term front we mean the side from which normally the smoking articles are extracted by the consumer, for example through the removal window 39, and therefore opposite the side toward which the closing lid 12 rotates when it is opened.

[0092] According to forms of embodiment described here, the rear wall 44 of the external containing body 14 and the rear wall 54 of the closing lid 12 form overall a rear wall 64 of the external shell 11 (see FIG. 2 for example).

[0093] According to other forms of embodiment described here, the lateral walls 48 of the external containing body 14 and the lateral walls 58 of the closing lid 12 can be at least double, that is, each comprising an external portion and an internal portion, as also described hereafter.

[0094] According to other forms of embodiment described here, the lateral walls 48 of the external containing body 14 and the lateral walls 58 of the closing lid 12 form overall lateral walls 68 of the external shell 11 (see FIGS. 1 and 2 for example).

[0095] In particular, the lateral walls 48 of the external containing body 14 can each have an upper edge 43, that can be part of said peripheral edge 49 that delimits the opening upper end 50. Similarly, the lateral walls 58 of the closing lid 12 can each have a lower edge 53, that can be part of said peripheral edge 61 that delimits the opening lower end 60 (see for example FIGS. 3, 4, 5, 6 and 9). In the closed condition of the closing lid 12, in which the lateral walls 68 are defined overall, the upper 43 and lower 53 edges meet, that is, they are essentially parallel and adjacent with respect to each other (see FIGS. 1 and 2 for example).

[0096] In possible forms of embodiment, see FIGS. 1-6, 9 and 11 for example, combinable with all the forms of embodiment described here, the upper edge 43, like the lower edge 53, can be transverse and inclined with respect to the base wall 46 of the external containing body 14.

[0097] The inclinations of the upper edge 43 and the lower edge 53 can be coordinated with each other, for example they can both be inclined downward toward the respective front walls 42 and 52, so as to meet in the closed condition of the closing lid 12 (see FIGS. 1 and 2 for example).

[0098] The inclination of the upper edge 43 and the lower edge 53 can be chosen for example in an interval between 15 and 60, in particular between 20 and 45, more in particular between 25 and 35. Possible inclination values of the upper edge 43 and the lower edge 53 can be for example 29, 30, 31, 32, 33, 34.

[0099] In other possible implementations, the upper edge 43, like the lower edge 53, can instead be parallel to the base wall 46 of the external containing body 14.

[0100] In accordance with the present description, the closing lid 12 can be configured so that, in its open condition (FIGS. 3 and 4), it allows the passage of the internal shell 16 from the closed configuration to the open configuration, since it can be rotated into a position where it does not interfere with the sliding of the internal shell 16.

[0101] The closing lid 12 can rotate to close and open the opening upper end 40 of the internal shell 16, from which the smoking articles are removed, and also the opening upper end 50 of the external containing body 14, through which the internal shell 16 is slidingly extracted and inserted.

[0102] According to the present description, the closing lid 12 is configured to be completely outside the internal shell 16, both in the closed and the open condition (see respectively FIGS. 1, 2 and FIGS. 3, 4).

[0103] In particular the closing lid 12 has the front wall 52 and the rear wall 54 external to the corresponding front wall 32 and rear wall 34 of the internal shell 16, just as the lateral walls 58 are disposed externally with respect to corresponding lateral walls 38 of the internal shell 16. To this end, the width and length of the closing lid 12 are greater than the width and length of the internal shell 16.

[0104] Furthermore, the closing lid 12 is configured to be completely outside the external containing body 14 as well, both in the closed configuration (FIGS. 1 and 2), and in the open configuration (FIGS. 3 and 4), just as in the open and extracted configuration (FIGS. 5, 6, 15a-15d, 17a-17c) of the internal shell 16 and in the intermediate passage configurations between one or the other of said configurations (see FIG. 11 for example).

[0105] To this end, the width and length of the closing lid 12 are essentially equal to the width and length of the external shell 11.

[0106] Consequently, in the closed condition of the closing lid 12, which also defines the closed configuration of the packet 10, (FIGS. 1 and 2), the front wall 52, the rear wall 54 and the lateral walls 58 of the closing lid 12 are coplanar to the corresponding front wall 42, rear wall 44 and lateral walls 48 of the external containing body 14 of the external shell 11. In this way, when it is closed, the closing lid 12 goes into abutment, for example with its peripheral edge 61, against the external containing body 14, in particular against the peripheral edge 49 that delimits the opening upper end 50, and is not therefore inserted into the external containing body 14.

[0107] The passage from the closed configuration to the open and extracted configuration is possible by positioning the closing lid 12 preliminarily in its open condition, so that the opening upper end 50 of the external containing body 14 is opened to allow the extraction of the internal shell 16. The sliding of the latter automatically causes the rotation of the closing lid 12 as well, thanks to the provision of the connection tongue 20, as described above. Indeed, after the closing lid 12 has been opened, it is possible to rotate it automatically, making the internal shell 16 slide with respect to the external containing body 14, since the closing lid 12 is also connected to the external containing body 14 by means of the connection tongue 20.

[0108] In accordance with possible forms of embodiment, the connection tongue 20 can be connected both to an external upper edge 45 of the rear wall 44 of the external containing body 14, and also to a closing upper edge 55 of the rear wall 54 of the closing lid 12. In particular the connection tongue 20 can be connected to the upper edge 45 and to the upper edge 55 by means of respective transverse folding lines 84, described in detail hereafter, so as to essentially make said double-jointed articulated connection between closing lid 12 and external containing body 14.

[0109] Moreover, in accordance with possible forms of embodiment, the connection tongue 20 can be part of the rear wall 54 of the closing lid 12, from which it can be made and separated by two parallel notches, or incisions 57, made in an intermediate position, which thus define two smaller lateral panels 59 of the rear wall 54 of the closing lid 12, on one side and the other of the connection tongue 20 that is thus created (see FIGS. 2 and 11). Therefore, the connection tongue 20 can be made through these two parallel notches 57, made on the rear wall 54 of the closing lid 12. The portion of rear wall 54 between the two notches 57 that forms the connection tongue 20 is not glued to the internal shell 16, while the portions of the rear wall 54 of the closing lid 12 located at the sides of the notches 57, that is, at the sides of the connection tongue 20, are instead glued to the internal shell 16.

[0110] In accordance with some forms of embodiment of the present description, the connection tongue 20 can therefore have a transverse width smaller than the transverse width of the rear wall 54 of the closing lid 12, and therefore also smaller than the length of the hinge 15. For example, the connection tongue 20 can be provided in a central position with respect to the rear wall 54 of the closing lid 12, and so the smaller lateral panels 59 of the rear wall 54 are positioned symmetrically with respect to the connection tongue 20.

[0111] In accordance with forms of embodiment described here, the connection tongue 20 can have a length or height equal to the height of the rear wall 54 of the closing lid 12.

[0112] More specifically, the proximal connection end 20a of the connection tongue 20 is attached to the closing lid 12 in a portion of the edge of the upper wall 51, more precisely along the edge that divides the upper wall 51 of the closing lid 12 from the rear wall 54 of the closing lid 12. The distal connection end 20b of the connection tongue 20 is attached to the peripheral edge that defines the access aperture of the external containing body 14. In practice, the connection tongue 20 is attached to the closing lid 12 and to the external containing body 14, while the closing lid 12 is hinged to the internal shell 16. The sliding travel that the internal shell 16 and the wrapper 13 are able to make is therefore equal to the length of the connection tongue 20 plus the height of the rear wall 54 of the closing lid 12, that is, equal to twice the height of the rear wall 54 of the closing lid 12. This limited sliding is sufficient to remove the internal shell 16, together with the wrapper 13, from the external containing body 14, so as to make visible the information possibly printed thereon.

[0113] In accordance with possible forms of embodiment, the rear wall 34 of the internal shell 16 can be provided with at least an upper folding flap or tab 34, rotatable around a folding line 34 (see FIGS. 7, 8, 10 and 18a for example) and obtained, for example, by means of lateral longitudinal notches or incisions 34.

[0114] The upper folding flap or tab 34 can be attached to said rear wall 54 of the closing lid 12.

[0115] The upper folding flap 34 can therefore be moved away from and toward a lying plane of the rear wall 34 of the internal shell 16.

[0116] The upper folding flap 34 can, for example, be rotated toward the outside of the internal shell 16.

[0117] In accordance with the present description, the upper folding flap 34 can therefore define the hinge 15 that connects the closing lid 12 rotatably to the internal shell 16 (see FIGS. 7, 8 and 10 for example), in this way allowing both the rotation of the closing lid 12 and also preventing the internal shell 16 from completely exiting from the external containing body 14. Therefore the one or more upper folding flaps 34, and the hinge 15 thus defined, can act as a stopping or holding element to prevent a complete and excessive sliding of the internal shell 16, beyond a partly extracted condition.

[0118] Moreover, by also providing a central notch 34 essentially parallel to the lateral longitudinal notches or incisions 34, it is possible to make two adjacent upper folding flaps 34, each rotatable as described above, autonomously one from the other (see FIG. 13 for example), which can therefore carry out the same functions as a single upper folding flap 34. Therefore, the upper folding flap 34 can be in a single piece, or it can be formed by two parts, attached to the closing lid 12, glued for example.

[0119] Consequently, the closing lid 12 can be rotatably connected to the rear wall 34 of the internal shell 16 by connection to one or more upper folding flaps 34, for example by gluing an internal surface of the rear wall 54 of the closing lid 12 to the upper folding flap 34 of the rear wall 34, thus obtaining, as we said, the hinge 15. Alternatively, it can be glued to the two upper folding flaps 34, if provided, of the internal shell 16 (see FIG. 13). In particular, it is possible to insert the upper folding flap/flaps 34 through the opening lower end 60 of the closing lid 12 and glue it/them to the internal surface of the rear wall 54.

[0120] The width of the upper folding flap/flaps 34, and possibly of the hinge 15 defined thereby, can therefore correspond to the width of the rear wall 54 of the closing lid 12.

[0121] In particular, the folding line 34 along which the upper folding flap/flaps 34 can be folded can define said hinge 15, and the corresponding lid hinging axis Y, around which the closing lid 12 can rotate. The folding line 34 can be in correspondence with the hinge 15 and located perpendicularly to the lateral longitudinal notches or incisions 34, thus forming said upper folding flap 34. Therefore, the lateral longitudinal notches or incisions 34 and the folding line 34 provided on the rear wall 34 allow the closing lid 12 to rotate around the hinge 15.

[0122] Moreover, the overall width of the upper folding flap/flaps 34, equal to the width of the rear wall 54, can also correspond, as we said, to the length of the hinge 15.

[0123] The closing lid 12 can be attached to the internal shell 16 by gluing the internal face of the rear wall 54 of the closing lid 12 to the upper folding flap 34 of the internal shell 16.

[0124] In this way the upper folding flap 34 of the rear wall 34 of the internal shell 16, where the closing lid 12 is glued, can bend along the folding line 34, when the closing lid 12 is rotated around the hinge 15. In practice, the folding line 34 coincides with the hinge 15.

[0125] When the closing lid 12 is in the closed condition, it forms a rectangular parallelepiped with the external containing body 14. In particular the front wall 52, the rear wall 54 and the two lateral walls 58 of the closing lid 12 are contiguous with the front wall 62, the rear wall 64 and the two lateral walls 68 of the external containing body 14 respectively.

[0126] In accordance with possible forms of embodiment, the internal shell 16 can be provided with protruding holding fins, or claws 17, configured to interfere with the closing lid 12, so as to interfere with the internal surface of the lateral walls 58 of the closing lid 12, and thus stably hold the closing lid 12 in its closed condition. The consumer, applying an upward traction force or a downward thrust force on the closing lid 12, can on each occasion easily overcome the resistance of the holding wings 17, to open and close the closing lid 12.

[0127] The holding fins 17 can be provided in a lateral position for example. For example, a pair of holding fins 17 can be provided which can be put at the sides of the removal window 39 and positioned so as to interfere with the closing lid 12 when the latter is in the closed condition, in abutment with the peripheral edge, so as to guarantee a more stable closure. For example, the holding fins 17 can be provided along longitudinal edges defined between the lateral walls 38 and the front wall 32, typically in an upper position, in substantial correspondence to the opening upper end 40 of the internal shell 16, for example near the removal window 39. The holding fins 17 can be made, for example, by means of incisions or notches, 18 which, when the lateral walls 38 and the front wall 32 of the internal shell 16 are folded to form the internal shell 16, determine the exit of a flap, or tongue, of material of the internal shell 16, that defines the holding fins 17. Generally, to obtain the protruding effect of the holding fins 17, the incisions or notches 18 can be made slightly curvilinear, or in any case not completely parallel to the longitudinal edges between the lateral walls 38 and the front wall 32.

[0128] FIGS. 14 and 20 are used to describe forms of embodiment of a single blank 80 from which it is possible to produce an external shell 11 in accordance with the present description.

[0129] In accordance with some forms of embodiment, the single blank 80 can include a first portion 80a, intended to form the external containing body 14, and a second portion 80b, intended to form the closing lid 12. The second portion 80b can include a transverse panel 54 intended to form the rear wall 54 of the closing lid 12. The transverse panel 54 can have two longitudinal notches or incisions 57, corresponding to the notches or incisions 57, that create a central panel 20 intended to form the connection tongue 20. The first portion 80a and the second portion 80b of the blank 80 are joined together by means of the central panel 20 alone.

[0130] The single blank 80 can include a plurality of elements that are described using, where possible, the same reference numbers, with apostrophe(s), of the corresponding walls of the external shell 11.

[0131] With reference, for example, to FIGS. 14 and 20, the blank 80 can be provided with two longitudinal folding lines 82 and with a plurality of transverse folding lines 84, which define, between the longitudinal folding lines 82, a panel 42 that forms the front wall 42 of the external containing body 14; a panel 44 that forms the rear wall 44 of the external containing body 14; a panel 46 that forms the base wall 46 of the external containing body 14; a panel 51 that forms the upper wall 51 of the closing lid 12; a panel 52 that forms the front wall 52 of the closing lid 12; a transverse panel 54 that forms the rear wall 54 of the closing lid 12; a reinforcement panel 52 that is folded at 180 and glued to the panel 52; reinforcement panels 51 that are folded at 180 , rotated toward the inside and glued to the panel 51.

[0132] The panel 42 can be provided with two lateral wings 48, that form respective external portions 48a of the lateral walls 48 of the external containing body 14 (FIG. 12), disposed on opposite sides of the panel 42, connected to the panel 42 by the longitudinal folding lines 82.

[0133] The panel 44 can be provided with two lateral wings 48, that form respective internal portions 48b of the lateral walls 48 of the external containing body 14 (FIG. 12), disposed on opposite sides of the panel 44, connected to the panel 44 by the longitudinal folding lines 82.

[0134] The panel 46 is disposed between the panel 44 and the panel 42. The panel 46 can be provided with two lateral reinforcement wings 46, that are folded at 180 , rotated toward the inside and glued to the panel 46, disposed on opposite sides of the panel 46, connected to the lateral wings 48 by transverse folding lines 84 and separated from the panel 46 and from the lateral wings 48 by means of respective incisions or notches 46 and 46.

[0135] The panel 52 can be provided with two lateral wings 58, that form respective external portions 58a of the lateral walls 58 of the closing lid 12 (FIG. 13), disposed on opposite sides of the panel 52, connected to the panel 52 by the longitudinal folding lines 82. The lateral wings 58 can have a trapezoidal shape for example.

[0136] The transverse panel 54 can have two pairs of notches or incisions, including said two longitudinal notches or incisions 57 and two transverse notches or incisions 57 that form both the central panel 20, that defines the connection tongue 20, and two lateral panels 59, that define the smaller lateral panels 59. Each pair of notches or incisions 57, 57 provide a longitudinal notch 57 and a transverse notch 57, respectively parallel or aligned to the longitudinal folding lines 82 and to the transverse folding lines 84. Typically, the longitudinal notch 57 and the transverse notch 57 are reciprocally disposed essentially at 90, with an L conformation, and each pair of notches 57, 57 can be symmetrical to the other with respect to the central panel 20. The central panel 20 is connected to the panel 51 and to the panel 44 by means of transverse folding lines 84 and is separated from the lateral panels 59 by means of the longitudinal notches 57. Moreover, the lateral panels 59 are connected to the panel 51 by means of transverse folding lines 84 and are separated from the panel 44 by means of the transverse notches 57.

[0137] The transverse panel 54 can also be provided with two lateral wings 58, that form respective internal portions 58b of the lateral walls 58 of the closing lid 12 (FIG. 13), disposed on opposite sides of the transverse panel 54. The lateral wings 58 and the reinforcement panels 51, glued, after suitable folding, respectively to the two lateral wings 58 and the panel 51, allow to reinforce the lateral walls 58 and the upper wall 52 of the closing lid 12.

[0138] The lateral wings 58 are connected to the transverse panel 54 by the longitudinal folding lines 82 and are separated, or able to be separated, from the lateral wings 48 by incisions, or notches, or breaking lines 48. The incisions, or notches or breaking lines 48 can define said upper edges 43 of the lateral walls 48 of the external containing body 14, and can possibly be made inclined, to provide an inclination to said upper edges 43. Consequently, the incisions, or notches, or breaking lines 48, together with the longitudinal notches or incisions 57 and transverse notches or incisions 57 can be provided to separate the first portion 80a of the blank 80 from the second portion 80b of the blank 80 which, as we said, can remain joined only by means of the central panel 20 that creates said connection tongue 20.

[0139] The reinforcement panels 51 can be connected to the lateral wings 58 by transverse folding lines 84 and separated from the lateral wings 58 and the panel 51 by respective incisions or notches 51 and 51.

[0140] The transverse panel 54 intended to form the rear wall 54 of the closing lid 12 has the two longitudinal notches 57 that create the connection tongue 20. Therefore, the second portion 80b intended to become the closing lid 12 and the first portion 80a intended to become the external containing body 14 are separated along incisions or notches or breaking lines 48 until arriving at the longitudinal notches 57. In practice, the portion central to the longitudinal notches 57 made on the transverse panel 54, intended to form the rear wall 54 of the closing lid 12, is not detached, leaving in that zone, where the connection tongue 20 is created, the link between the first portion 80a and the second portion 80b. The portion of rear wall 54 of the closing lid 12 that forms the connection tongue 20, as we said before, will not be glued, while the portions of the transverse panel 54 at the sides of the connection tongue 20 will be glued to the two portions that form the upper folding flap 34 of the internal shell 16.

[0141] In possible implementations, the folding lines 34, 82, 84 according to the present description can be made for example by pre-creasing the relatively rigid material that makes up the external shell 11 and the internal shell 16. For example, blind or continuous pre-creasing operations can be provided, or through pre-creasing or in segments. According to the present description, by blind pre-creasing we mean a shaping made with a deformation by crushing the thickness of the material, and by through pre-creasing we mean a shaping in which at least one cut segment is provided passing through the thickness of the material.

[0142] In possible implementations, the notches or incisions 18, 34, 34, 46, 46, 48, 51, 51, 57, 57 can be made for example by dinking or cutting the relatively rigid material that makes up the external shell 11 and the internal shell 16.

[0143] It is therefore clear from the above that, from a single blank 80 the external shell 11 can be made, including the closing lid 12, the external containing body 14 and the connection tongue 20.

[0144] It is also obvious that the single blank 80 from which, in a single body, the closing lid 12, the external containing body 14 and the connection tongue 20 are made, is a blank that can be processed without difficulty to produce rigid packets of the hinged-lid, slide-open type in conventional packaging machines, without requiring substantial modifications or adaptations thereof, with the additional provision of making the longitudinal notches 57 and the transverse notches 57 as above, to define the central panel 20 and hence the corresponding connection tongue 20 of the final external shell 11.

[0145] For example, the blank 80 according to the present description and described using FIGS. 14 and 20 can be made of a relatively rigid sheet material, such as cardboard, paper or suchlike.

[0146] FIG. 19 is used to describe forms of embodiment of a single blank 90 usable to make the internal shell 16 that is folded around the wrapper 13. The blank 90 comprises: a main panel 32 that constitutes the front wall 32 of the internal shell 16; two panels 38 that constitute the lateral walls 38 of the internal shell 16, are disposed on opposite sides of the main panel 32, and are divided from the main panel 32 by two longitudinal lines of weakening 301; and two panels 234 that together constitute the rear wall 34 of the internal shell 16, are disposed at the sides of the two panels 38 and are divided from the panels 38 by a respective longitudinal line of weakening 302. The lateral longitudinal notches or incisions 34 are made along the longitudinal lines of weakening 302 that divide the panels 234, that form the rear wall 34 of the internal shell 16, from the adjacent panels 38 that form the lateral walls 38 of the internal shell 16. In the same way, the folding line 34 is made on the panels 234 so as to form the upper folding flap 34 divided into two portions, one for each panel 234, which will then be glued to the rear wall 54 of the closing lid 12. The main panel 32 has the removal window 39, for example defined by a U-shaped cut. The blank 90 is folded around the wrapper 13 and attached to it.

[0147] Furthermore, it is obvious that the packet 10 according to the present description can be attractive both for conservative smokers, in that it can be used as a traditional packet when put in the open configuration (FIGS. 3 and 4), and also for innovative smokers, when put in the open and extracted configuration (FIGS. 5 and 6).

[0148] Furthermore, the internal 11 and external shells 16 used are easily processed by traditional packaging machines.

[0149] Moreover, since the internal shell 16 is essentially comparable to that of traditional packets, except for the possible inclusion of the upper folding flap 34 as above, it is quite evident that the same internal shell 16 maintains its characteristics of resistance and rigidity that make traditional packets appreciated by many smokers.

[0150] It is clear that modifications and/or additions of parts may be made to the packet 10 as described heretofore, without departing from the field and scope of the present invention.

[0151] It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of packet 10, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.

[0152] Although the above refers to forms of embodiment of the invention, other forms of embodiment can be provided without departing from the main field of protection, which is defined by the following claims.
