• the present invention relates to a package of smoking articles of rigid type with hinged lid and to the corresponding wrapping method and packing machine.
• a rigid package of cigarettes with a hinged lid comprises a soft inner envelope enclosed within a rigid outer container.
• the access to the inner envelope is obtained by means of a lid, also of rigid type, provided for the outer container and hinged to the same.
• the soft inner envelope is made by wrapping a group of cigarettes around a suitably shaped wrapping sheet.
• the wrapping sheet is made of metallic material or of multilayer paper or metalized paper, typically with aluminum.
• the soft inner envelope is made by wrapping the wrapping sheet on the group of smoking articles without sealing the same. In this way, the group of cigarettes is protected by contact with external agents even without the need for gluing and sealing which are costly in terms of time and cost.
• the wrapping sheet is made of a separable portion, which is detachable by the user at the first opening. This is normally achieved by means of a separable portion of metalized paper. Said separable portion is pre-engraved along a separation line for allowing the user to simply tear the separable portion without excessive effort and in a well defined area. Therefore, to access the group of smoking articles, a user can easily grab a folded flap of the wrapping sheet by lifting and pulling part of the separable portion that can be easily torn by continuing the lifting and pulling action .
• the detached portion When removed, the detached portion becomes an independent element with respect to the package of cigarettes and, therefore, bothersome to the user.
• the user is forced to immediately place the detached portion in the trash after opening.
• the detached portion is often dispersed by the user thus becoming a polluting element.
• the patent EP 1591027 Bl describes a package of cigarettes wherein the separable portion at the extraction opening is glued to the lid of the outer container.
• the separable portion is detached automatically when the user lifts the lid for the first time.
• Said separable portion becomes, therefore, an integral part of the outer container while remaining glued to the inner surface of the face and upper wall of the lid.
• the first opening moreover, requires the application of a sufficient force, such as to allow the closure element to break the peripheral pre-engravings , made on the portion of the underlying inner container, adapt to define the cigarette extraction opening. It would therefore be desirable to have a package of smoking articles, in particular of cigarettes, able to minimize the above drawbacks. In particular, it would be desirable to have a package of smoking articles having an improved usability for the user, simplifying the opening and closing operations of the same.
• Object of the present invention is to provide a package of smoking articles, in particular of cigarettes, of rigid type with a hinged lid having an improved usability and, at the same time, easy and inexpensive to manufacture.

• the collar 53 comprises a first wall, not removable and adapted to wholly cover the front portion of the inner envelope, and a second wall, which is also not removable and adapted to partially cover the upper portion of the inner envelope.
• the abovementioned walls are separated by a hinge line which extends along the connection edge between the front portion and the upper portion of the inner envelope.
• the particular conformation of the collar 53 allows to define the movable portion 113 so that this extends between the connection hinge 443 and an upper portion of the inner envelope at the upper wall 343 or with the peripheral edge 153 of the collar 53 superimposed with the upper portion.
• connection hinge 443 or, vice versa, to the connection edge between the front and upper portions of the inner envelope.
• the movable portion 113 is arranged below the collar portion 53 formed on the upper portion of the inner envelope 13 until the user performs the first opening.
• the engraving which defines the movable portion 113 at the upper portion may be carried out at the perimeter edge 153 of the collar superimposed to the upper portion thereof.
• the collar 53 is obtained in line starting from the respective reel of wrapping material, in particular of cardboard type material.
• the second cutting unit separates cut pieces of cardboard from the continuous tape from the respective reel of wrapping material prior to the application on the inner envelope itself.
• the knife, or blade, provided on the second cutting unit shapes the cut piece forming the collar 53 in inverted "U" shape, i.e. with a recess at the area in contact with the face wall 133 of the outer container 33.
• a third wrapping unit interposed between the first and the second wrapping unit allows, in fact, to couple the collar 53 to the inner envelope before folding the blank, as previously described, carrying out the fold on the sides and at the same time on the top portion of the same.
• the third wrapping unit allows to apply the collar 53 wholly covering the front portion and to partly cover the upper portion of the inner envelope visible when the latter is inserted within the outer container 33.
• the engraving device also carries out the movable portions 113 to extend between the connection hinge 443 and an upper portion of the inner envelope 13 at the upper wall 343 or with the peripheral edge 153 of the collar 53 superimposed on the upper portion.
• a further embodiment (not shown) of the package of smoking articles, in particular of cigarettes, according to the present invention differs from the embodiments previously described and shown in Figures 1-3 for the presence of a collar integrated to the outer container.
• the collar can be shaped as described previously in one of the embodiments described and illustrated and by carrying out on the rigid outer container an embossed portion at the lid. Said embossed portion reproduces the shape of a traditional collar, or of one of the collars described above for the second or third embodiment, carrying out a collar integrated with the front wall and with the lateral walls of the outer container.
• the coupling of the lid with the remaining part of the outer container is guaranteed even if the same is made by folding a single blank.
• the shaping device before carrying out the folding of the blank around the inner envelope on the fifth wheel, the shaping device generates an embossed portion carrying out a collar integrated to the front wall of the outer container at the extraction opening. The lid is, therefore, superimposed with the embossed portion when arranged in the second closing position.
• the collar allows the joining of the lid with the remaining part of the outer container while maintaining a sufficiently rigid conformation which avoids the common defect of the "smiling" package, that is, one that leaves a gap between the lid and the front wall.
• the collar may be provided with inscriptions and/or logos and/or images on the outer surface visible to a user.
• the package of smoking articles described above has numerous advantages .
• the package of smoking articles allows the opening of the outer container and the access to the extraction opening with a single gesture, acting by means of the simple rotation and arrangement of the lid in the first opening position.
• the access to the group of cigarettes is immediate and simultaneous with the lid rotation.
• the ability to maintain unchanged the face and, at least partially, upper appearance of the inner envelope allows to improve the usability and ergonomics of the package of smoking articles, previously described in an exemplifying plurality of alternative embodiments, with respect to similar packages of smoking articles of the type known.
• by obtaining the extraction opening starting from the connection hinge it is possible to carry out the opening of the package without detaching and dispersing wrapping material leaving the aesthetic appearance of the package itself nearly unchanged. This leads to the pleasant user experience of having a like- new package available at each cigarette extraction.
• the particular shape of the movable portion and/or of the collar creates a barrier adapted to maintain aroma and is simply and economically implemented.
• the same shape helps to prevent the dispersion of tobacco particles when the package is open.
• the extension of the collar to entirely cover the front portion and/or part of the upper portion also allows to obtain a large surface of the same on which inscriptions and/or logos and/or images can be carried out so as to be visible to the user when the package is open.
• the package of smoking articles described above can be produced in a simple and economic way by using a standard packing machine (which only requires minor modifications) .
• the production of the package does not require, therefore, the use of special packing machines of considerable design and production cost.
• said package can also be used to contain articles other than cigarettes, such as food products (candies, chocolates or other sweets) .
