[0001] "PACK FOR SMOKING ARTICLES WITH A HINGED LID AND PROVIDED

[0002] WITH A SEALED WRAP"

[0003] CROSS-REFERENCE TO RELATED APPLICATIONS

[0004] This Patent Application claims priority from Italian Patent Application No. 102023000016293 filed on August 1st’, 2023, the entire disclosure of which is incorporated herein by reference.

[0005] TECHNICAL FIELD

[0006] The present invention relates to a pack for smoking articles with a hinged lid and provided with a sealed wrap.

[0007] The present invention is advantageously applied to the manufacturing of a pack for cigarettes, to which the following disclosure will explicitly refer without thereby losing generality.

[0008] PRIOR ART

[0009] Packs for cigarettes with a hinged lid are the most widespread packs for cigarettes currently on the market as they are simple to manufacture, easy and practical to use, and offer good protection to the cigarettes contained on their inside.

[0010] A pack for cigarettes with a hinged lid comprises a wrap consisting of a group of cigarettes wrapped in a wrapping sheet and an outer casing which accommodates the wrap. The outer casing consists of a cup- shaped container, which accommodates the wrap containing the group of cigarettes, and a lid, which is also cup-shaped and is hinged to the container.

[0011] In a traditional pack for cigarettes, the group of cigarettes is wrapped in a rectangular wrapping sheet made of metallic paper without glue. Such type of pack results to be easily recyclable but it does not allow preserving the integrity of the tobacco of the cigarettes. In order to preserve the integrity of the tobacco of the cigarettes, it has been proposed to manufacture a sealed (waterproof) wrap consisting of a wrapping sheet made of paper material rendered waterproof and heat- sealable and which has an extraction opening for extracting the cigarettes closed by a reusable closing label made of a plastic material. Such type of pack allows preserving the tobacco of the cigarettes, but it results to be more difficult to recycle as a separation of the materials is required by the smoker (namely once the smoker has used up the pack for cigarettes, said smoker should separate the closing label from the rest of the sealed wrap).

[0012] Patent applications WO2016001826 Al and WO2023079447A1 describe a pack for cigarettes wherein a wrap which encloses a group of cigarettes has at the top and at the front a lift-up portion which is separated from the rest of the wrap by a pre-weakened separation line and is torn upon the first opening of the lid.

[0013] Patent EP2064134B 1 describes a rigid pack for cigarettes with a hinged lid, wherein the hinge of the lid is arranged in the area of a narrower wall.

[0014] Patent EP0007423B 1 describes a rigid pack for cigarettes with a hinged lid and provided with a sealed inner wrap.

[0015] Patent EP2817232B 1 describes a rigid pack for cigarettes with a hinged lid and having a cross-section which continuously varies from a trapezoidal upper wall to a trapezoidal lower wall.

[0016] Patent application US2020115146A1 describes a rigid pack for cigarettes with a hinged lid and provided with a pair of coupons.

[0017] DESCRIPTION OF THE INVENTION

[0018] The object of the present invention is to provide a pack for smoking articles with a hinged lid and provided with a sealed wrap, said pack allowing preserving the tobacco of the cigarettes, having a greater environmental sustainability and, simultaneously, being simple and intuitive to use.

[0019] In accordance with the present invention, a pack for smoking articles with a hinged lid and provided with a sealed wrap is provided, according to what claimed in the appended claims.

[0020] The claims describe embodiments of the present invention forming integral part of the present description.

[0034] PREFERRED EMBODIMENTS OF THE INVENTION

[0035] In Figures 1, 2 and 3, reference numeral 1 indicates, as a whole, a rigid pack for cigarettes with a hinged lid. The pack 1 for cigarettes comprises a cup- shaped container 2 made of cardboard or rigid paperboard and a sealed wrap 3 (partially illustrated in Figure 3 and completely illustrated in Figure 4) with a parallelepiped shape and accommodated inside the container 2.

[0036] The container 2 has an open upper end and is provided with a lid 4, which is cup-shaped and is hinged to the container 2 along a hinge 5 (illustrated in Figure 2) for rotating, with respect to the container 2, between an open position (illustrated in Figure 3) and a closed position (illustrated in Figures 1 and 2) of the open upper end. The container 2 has a substantially rectangular parallelepiped shape oriented according to a vertical development direction, is cup-shaped, and has the upper end open, a bottom wall 6 opposite the open upper end, a front wall 7 and a rear wall 8 (in which the hinge 5 is made) parallel to and opposite each other, and two side walls 9 parallel to and opposite each other and each of which is smaller than the front wall 7 and the rear wall 8 of the container 2. Namely, each side wall 9 of the container 2 is smaller than the front wall 7 and the rear wall 8 of the container 2; in other words, the two side walls 9 have the same dimension and are smaller than the walls 7 and 8 which have the same dimension.

[0037] The lid 4 has a substantially rectangular parallelepiped shape, is cup-shaped, and has an open lower end (facing the open upper end of the 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 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 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 container 2 when the lid 4 is in the closed position and is hinged to the rear wall 8 of the container 2 along the hinge 5), and two side walls 13 parallel to and opposite each other (which are parallel to and aligned with, in particular coplanar and adjacent to, the side walls 9 of the container 2 when the lid 4 is in the closed position). Each side wall 13 of the lid 4 is smaller than the front wall 11 and the rear wall 12 of the lid 4; namely the two side walls 13 have the same dimension and are smaller than the walls 11 and 12 which have the same dimension.

[0038] According to what is illustrated in Figures 3 and 10, the pack 1 for cigarettes comprises a collar 14, which is fixed (normally by means of gluing) inside the container 2 so as to partially project out of the open upper end and engage a corresponding inner surface of the lid 4 when the lid 4 is arranged in the mentioned closed position.

[0039] The collar 14 comprises a front wall 15 which is superimposed and glued to the front wall 7 of the container 2 and two side walls 16 which are folded at 90° relative to the front wall 15 and are superimposed and glued to the side walls 9 of the container 2. Each side wall 16 of the collar 14 is smaller than the front wall 15 of the collar 14; namely, the two side walls 16 of the collar 14 have the same dimension and are smaller than the front wall 15 of the collar 14.

[0040] The front wall 15 of the collar 14 has a window 17 which is arranged at the top, is “U”- shaped, is delimited by an edge 18 and exposes an upper area of the front wall of the sealed wrap 3. In the embodiment illustrated in Figure 9, the collar 14 comprises only the front wall 15 and the two side walls 16. According to another embodiment illustrated in Figure 10, the collar 14 also comprises two (small) rear walls, each of which is connected to a respective side wall 16, is folded at 90° relative to the respective side wall 16, and is laid against (and possibly glued to) the rear wall 8 of the container 2. In accordance with a variation not illustrated, said rear walls can have a different dimension with respect to what illustrated in Figure 9; furthermore, in accordance with a further variation not illustrated, the collar 14 can also comprise one single rear wall.

[0041] The collar 14 has the function to hold the lid 4 in the closed position with a certain force so as to prevent undesired openings of the lid 4; such “locking” function of the lid 4 in the closed position is carried out thanks to the fact that when the lid 4 is in the closed position, the collar 14 partially projects from the open end of the container 2 and thus engages a corresponding inner surface of the lid 4: in this manner, in order to open the lid 4 it is necessary to elastically and slightly deform the lid 4 and / or the collar 14 and it is thus necessary to apply a certain force to the lid 4 in order to open the lid 4. According to embodiments illustrated in the accompanying figures, the front wall 15 of the collar 14 is provided with a pair of claws which laterally project for engaging with interference the lid 4 when the lid 4 is in the closed position so as to hold with greater force the lid 4 in the closed position. According to a different embodiment not illustrated, the front wall 15 of the collar 14 is without the claws.

[0042] According to what is illustrated in Figure 5, the sealed wrap 3 contains a group 19 of cigarettes composed of twenty filter cigarettes arranged on three layers; according to other embodiments not illustrated, the group 19 of cigarettes could comprise a different number of cigarettes and / or a different arrangement of the cigarettes.

[0043] According to what is illustrated in Figures 6 and 7, the sealed wrap 3 also contains a reinforcing element 20 which is in direct contact with the group 19 of cigarettes and envelopes the group 19 of cigarettes. The reinforcing element 20 is made of cardboard or rigid paperboard (totally similar to the carboard or rigid paperboard of which the container 2 is made), is “U”-shaped and comprises a front wall 21 with a rectangular shape, which is arranged in contact with a front wall of the group 19 of cigarettes and a pair of side walls 22, which are connected to the opposite sides of the front wall 21 and are arranged in contact with the side walls of the group 19 of cigarettes. The front wall 21 has a window 23 which is arranged at the top, is “U”-shaped, and facilitates the extraction of the cigarettes from the group 19 of cigarettes as it exposes an upper area of the front wall of the group 19 of cigarettes.

[0044] According to a different embodiment, the sealed wrap 3 is without the reinforcing element 20.

[0045] According to what is illustrated in Figure 4, the sealed wrap 3 has a parallelepiped shape, encloses the group 19 of cigarettes, and consists of a wrapping sheet 24 (illustrated in Figure 8) wrapping the group 19 of cigarettes and is made of paper material rendered heat-sealable and waterproof; consequently, all the components of the pack 1 for cigarettes are made of paper material and can thus be disposed in the same waste collection container for being recycled together. In particular, the wrapping sheet 24 has a rectangular shape, comprises at least one layer of airproof and heat-sealable plastic (or bioplastic) material, is folded in a known manner around the group 19 of cigarettes, and is (preferably) stabilized by means of heat-sealing (by heat-sealing the superimposed portions of the wrapping sheet 24) in order to make the sealed wrap 3 hermetically sealed (namely airproof). In accordance with an embodiment variation, the sealed wrap 3 could also be made of a different material, for example a plastic material.

[0046] The sealed wrap 3 comprises a removable portion 25 at least partially delimited by an (at least one) incision 26 which is made through the wrapping sheet 24 and defines a tearing line; the incision 26 is a non-through incision, namely does not completely pass through the thickness of the wrapping sheet 24 and which thus preserves the waterproofness of the wrapping sheet 24.

[0047] According to a preferred embodiment illustrated in Figure 4, the sealed wrap 3 which encloses the group 2 of cigarettes is made by folding the rectangular wrapping sheet 24 around the group 19 of cigarettes making a transverse sealing fin (not illustrated) arranged in the area of a rear wall of the sealed wrap 3 and two longitudinal sealing fins 27 (only one of which is illustrated) which are arranged in the area of two side walls of the sealed wrap 3 and are folded against the side walls of the sealed wrap 3; in particular, the rectangular wrapping sheet 24 is initially folded making the transverse fin so as to form a tube having two open ends in the area of the side walls and thus each tubular open end is closed by making a respective longitudinal sealing fin 27.

[0048] According to a preferred embodiment illustrated in Figure 4, the removable portion 25 extends to an upper area of the sealed wrap 3, namely completely affects an upper portion of the sealed wrap 3; consequently, the removable portion 25 extends in part of a front wall, in part of the side walls and in the whole upper wall of the sealed wrap 3. According to other embodiments not illustrated, the removable portion 25 extends in a more limited manner in the upper portion of the sealed wrap 3: for example the removable portion 25 could be arranged only on one side of the sealed wrap 3 and thus the removable portion 25 could extend only in part of the front wall, only in part of one single side wall and only in part of the upper wall of the sealed wrap 3.

[0049] Preferably, both longitudinal sealing fins 27 externally have through cuts 28 (only one of which is illustrated in Figure 4 and both are illustrated in Figure 8) in the area of the incision 26 for favouring the breaking of the wrapping sheet 24 in the area of the two longitudinal sealing fins 27 in which the wrapping sheet 24 is superimposed and heat- sealed and thus is thicker and more resistant; obviously, if the removable portion 25 is asymmetrical and affects only one longitudinal sealing fin 27 then only this longitudinal sealing fin 27 has the through cut 28. It is important to highlight that each through cut 28 affects only an outer part of the longitudinal sealing fin 27 and does not thus affect the entire longitudinal sealing fin 27 for not compromising the hermetic seal of the sealed wrap 3.

[0050] Said one or more through cuts 28 advantageously favour the laceration of the sealed wrap 3 along the incision 26.

[0051] According to what is illustrated in Figures 3 and 9, the side walls 16 of the collar 14 are shaped so as to expose (namely so as not cover) an upper part of the side walls of the sealed wrap 3 (and thus an upper part of the longitudinal sealing fins 27 which project from the side walls of the sealed wrap 3) in the area of the removable portion 25. In this manner a user, after opening the lid 4, can grab with his / her fingers a part of the removable portion 25 in the area of a side wall of the sealed wrap 3 (namely in the area of a longitudinal sealing fin 27) for pulling upwards, and thus tear, the removable portion 25 which by separating from the rest of the sealed wrap 3 determines the opening of the sealed wrap 3. To such regard, it is important to observe that each longitudinal sealing fin 27 is separated from and only laid against the rest of the sealed wrap 3 and thus it is very easy and quick for the user to hold tight with his / her two fingers the part of the longitudinal sealing fin 27 left free (exposed) from the collar 14 for pulling upwards, and thus tear, the removable portion 25; namely each longitudinal sealing fin 27 constitutes an excellent gripping point which enables easily and firmly grabbing a side end of the removable portion 25 for proceeding with a quick and safe tear removal of the removable portion 25.

[0052] Summarizing, upon the first opening of the lid 4, the user grabs and tears the removable portion 25 of the sealed wrap 3 in the area of a part of the longitudinal sealing fin 27 left free (exposed) from the collar 14 (thus determining the opening of the sealed wrap 3); in fact, the removal of the removable portion 25 of the sealed wrap 3 determines the creation in the sealed wrap 3 of an extraction opening for extracting the cigarettes of the group 19 of cigarettes.

[0053] In the embodiment illustrated in the accompanying figures, each side wall 16 of the collar 14 has a window 29 which is delimited by a curved edge 30 (but it could also be linear) and has an approximately triangular shape. It is important to highlight that each window 29 does not affect the whole area of the respective side wall 16 of the collar 14, as it is useful for each side wall 16 of the collar 14 to have, close to the front wall 15, the same longitudinal size as the front wall 15 so as to guarantee the presence and the functionality of the respective claw.

[0054] In the embodiment illustrated in Figure 10, the collar 14 also comprises two (small) rear walls, each of which is connected to a respective side wall 16.

[0055] In the embodiment illustrated in the accompanying figures, the collar 14 leaves uncovered the rear comer (or the rear comers) of the sealed wrap 3. Advantageously, after the tearing of the removable portion 25 of the sealed wrap 3 such shape of the collar 14 makes the extraction of the first cigarette of the group 19 of cigarettes simpler. In other words, for the user it will be simple to grab the cigarette of the group 19 of cigarettes arranged in the rear corner of the sealed wrap 3 as it will be possible to pinch it between two fingers.

[0056] In the embodiment illustrated in the accompanying figures, the collar 14 is symmetrical and thus has two specular windows 29 in the two side walls 16; in this manner the user can freely choose whether to tear the removable portion 25 from the right or from the left and thus the pack 1 for cigarettes is adapted for right-handed and left-handed users. According to a different embodiment not illustrated, the collar 14 is asymmetrical and thus has the window 29 in one single side wall 16. In Figure I l a blank 31 is illustrated which is folded around the sealed wrap 3 (around which the collar 14 has been folded in advance) for forming the container 2 and the lid 4. The embodiments described herein can be combined with one another without departing from the scope of protection of the present invention.

[0057] In the embodiments illustrated in the accompanying figures, the longitudinal and transverse corners are right corners; alternatively, the longitudinal and / or transverse corners could be rounded or bevelled comers.

[0058] In the embodiments illustrated in the accompanying figures, the pack 1 for cigarettes contains a group 19 of cigarettes; alternatively, the pack 1 for cigarettes can contain any other type of smoking articles such as for example cigars, electric or electronic cigarettes (namely cigarettes that generate an aerosol without combustion), cartridges and refills for electronic cigarettes, new generation cigarettes.

[0059] The pack 1 for cigarettes described above has numerous advantages.

[0060] Firstly, the pack 1 for cigarettes described above preserves the tobacco of the cigarettes as, before the first opening, the sealed wrap 3 seals the group 19 of cigarettes (namely completely insulates the group 19 of cigarettes from the external environment). Furthermore, such pack 1 for cigarettes seals the group 19 of cigarettes without the use of a closing label usually made of plastic material (and thus with a high environmental impact).

[0061] In particular, considering that the entire sealed wrap 3 is made with one single wrapping sheet 24 consisting of one single paper wrapping material (thus compatible with the wrapping material of which the container 2, the lid 4 and the collar 14 are made), the pack 1 for cigarettes described above has a greater environmental sustainability; namely, the manufacturing of the sealed wrap 3 requires the use of one single paper wrapping material and thus allows reducing the variety of wrapping materials with respect to a similar known pack 1 for cigarettes provided with a sealed wrap.

[0062] The pack 1 for cigarettes described above has a very simple and intuitive use, as it is totally natural for a user (also without any instructions in advance) to laterally grab the removable portion 25 of the sealed wrap 3 in the area of a part of the longitudinal sealing fin 27 left free (exposed) from the collar 14 for pulling the removable portion 25 and thus determining the opening of the sealed wrap 3. The pack 1 for cigarettes described above allows the user to verify in a sure and unequivocable manner the integrity of the sealed wrap 3 guaranteeing the user that the pack 1 for cigarettes has never been previously opened; in fact, the presence of the removable portion 25 of the sealed wrap 3 guarantees that the sealed wrap 3 is totally whole and has never been previously opened.

[0063] Finally, the pack 1 for cigarettes described above can be manufactured in a standard packing machine for rigid packs for cigarettes with a hinged lid with very few modifications. Therefore, the production of the pack 1 for cigarettes described above does not require the use of an expensive special (i.e. specially designed for this type of packs for cigarettes) packing machine.
