This patent application is a U.S. national phase of International Patent Application No. PCT/IB2021/050720 filed Jan. 29, 2021, which claims the benefit of priority from Italian patent application no. 102020000001873 filed on Jan. 31, 2020, the respective disclosures of which are each incorporated herein by reference in their entireties.
The present invention relates to a rigid pack of smoking articles provided with a hinged and sliding lid.
The present invention finds advantageous application to a pack of cigarettes, to which the following description will make explicit reference without thereby losing generality.
The rigid packs of cigarettes with hinged lids are currently the most widespread packs of cigarettes on the market as they are simple to manufacture, are easy and practical to use, and offer effective protection to the cigarettes contained within.
A rigid pack of cigarettes with a hinged lid comprises a group of cigarettes wrapped in a wrapping sheet of metallized paper to define an inner wrap and a rigid container that houses the inner wrap; the container is cup-shaped, has an open top 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 the container, between an open position and a closed position of the open end. A collar is normally provided, which is folded and connected to the inside of 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.
A new type of rigid pack of cigarettes has recently been proposed, described for example in the patent application EP1466844A1 and wherein the lid performs a roto-translation (i.e., both a translation and a rotation) to pass from the closed position to the open position and vice versa. The opening of this rigid pack of cigarettes is simple and intuitive even for a child and therefore said rigid pack of cigarettes cannot be classified as “child-proof” or “child resistant”, namely, able to prevent children from opening the same. Normally, a pack of cigarettes is classified as “child-proof” if its opening, i.e., the possibility of accessing the content, is precluded by mechanisms that an uninformed user would not be able to unlock. In other words, a pack of cigarettes is defined as “child-proof” when its opening (and therefore access to the content) is not immediate and requires the application of particular force or torque in predetermined points, or sequences of non-intuitive movements for the effective unlocking of the opening of the pack of cigarettes.
The patent application DE102007009251A1 describes a rigid pack of cigarettes comprising: a container, a hinged lid that performs a roto-translation (i.e., both a translation and a rotation) to pass from the closed position to the open position and vice versa, a collar glued on the inside of the container, and a slider which is firmly connected to the lid and is slidingly coupled to the container.
The purpose of the present invention is to provide a rigid pack of smoking articles provided with a hinged and sliding lid that can be classified as “child-proof”, namely, able to prevent children from opening the same, and at the same time, easy and inexpensive to implement.
According to the present invention, a rigid pack of smoking articles provided with a hinged and sliding lid, according to what is claimed in the attached claims is provided.
The claims describe preferred embodiments of the present invention forming an integral part of the present description.
The present invention will now be described with reference to the attached drawings, which illustrate some non-limiting embodiments thereof, wherein:
In
The pack 1 of cigarettes comprises a container 2 made of cardboard or rigid paperboard and is cup-shaped. The container 2 has an open top end 3 (illustrated in
The container 2 has a substantially rectangular parallelepiped shape oriented according to a prevalently vertical development direction, is cup-shaped, and has an open top end 3, a bottom wall 5 opposite the open top end 3, a front wall 6 and a rear wall 7 which are parallel to and opposite one another, and two side walls 8, which are parallel to and opposite one another. Four longitudinal edges are defined between the front 6, rear 7 and side 8 walls of the container 2, while four transverse edges are defined between the walls 6, 7 and 8 and the bottom wall 5 of the container 2.
The lid 4 has a substantially rectangular parallelepiped shape, is cup-shaped, and has an open bottom end (facing the open top end 3 of the container 2 when the lid 4 is in the closed position), a top wall 9 (which is parallel to and opposite the bottom wall 5 of the container 2 when the lid 4 is in the closed position), a front wall 10 (which is parallel to and aligned with the front wall 6 of the container 2 when the lid 4 is in the closed position), a rear wall 11 (which is parallel to and aligned with the rear wall 7 of the container 2 when the lid 4 is in the closed position), and two side walls 12 which are parallel to and opposite one another (which are parallel to and aligned with, in particular coplanar and adjacent to, the side walls 8 of the container 2 when the lid 4 is in the closed position). Four longitudinal edges are defined between the front 10, rear 11 and side 12 walls of the lid 4, while four transverse edges are defined between the walls 10, 11 and 12 and the top wall 9 of the lid 4. The longitudinal edges and the transverse edges of the lid 4 are parallel to and aligned with the corresponding longitudinal and transverse edges of the container 2 when the lid 4 is in the closed position.

According to an embodiment not illustrated, the collar 14 can also comprise a bottom wall which is arranged in contact with the bottom wall 5 of the container (in other words, it is arranged between the bottom wall 5 of the container 2 and the inner wrap 13).
Furthermore, the pack 1 comprises a slider 19 which is firmly connected to the lid 4 and is slidingly coupled with the container 2 to slide relative to the container 2 along a sliding direction D1.
The slider 19 comprises a front wall 42 which is arranged facing (and at least partially rests against) the front wall 6 of the container 2 and is free to slide with respect to the front wall 6 of the container 2 along the sliding direction D1.
Preferably, the flap 15a of the front wall 15 of the collar 14 is arranged between the front wall 42 of the slider 19 and the front wall 6 of the container 2.
Therefore, the front wall 42 of the slider 19 slides freely relative to the container 2, relative to the inner wrap 13 and relative to the collar 14.
The slider 19 comprises, furthermore, a pair of side walls 23 which extend from the front wall 42, in particular from opposite sides of the front wall 42, and are squarely folded (i.e., by 90°) relative to the front wall 42 and against the side walls 16 of the collar 14 (i.e., the side walls 16 of the collar 14 are arranged between the side walls 23 of the slider and the side walls 8 of the container 2).
Preferably, the slider 19 comprises a pair of tabs 23a which extend from the lower side of the side walls 23 of the slider 19, are connected to the side walls 23 of the slider 19 by means of hinge lines and are folded around said hinge lines to be each arranged in contact with the respective side wall 23. In other words, each tab 23a is rotated by 180° around its hinge line and is arranged in contact with (i.e., in abutment against) the side wall 23.
The function of the tabs 23a is to limit the upper sliding of the slider 19; in particular, the sliding of the slider 19 upwards is blocked when the tabs 23a arrive at the side walls 16 of the collar 14.
Furthermore, the slider 19 has a rear wall 20 which is arranged in contact with the rear wall 7 of the container 2 and a rear wall 21 (i.e., a connection panel) which is connected to the rear wall 20 by means of a hinge 22 and is arranged in contact with the rear wall 11 of the lid 4.
In particular, the rear wall 20 of the slider 19 rests only against the rear wall 7 of the container 2 and therefore can slide freely with respect to the rear wall 7 along a sliding direction Dl while the rear wall 21 of the slider 19 is glued (by means of permanent glue) to the rear wall 11 of the lid 4 and therefore is rigidly and firmly fixed to the rear wall 11. The hinge 22 which connects the two rear walls 20 and 21 of the slider 19 allows the lid 4 (glued to the rear wall 21 of the slider 19) to rotate between the closed position (illustrated in
With reference to
In detail, according to the illustrated embodiment, the rear wall 20 of the slider 19 is formed by the two panels 20′ arranged side by side and coplanar. Similarly, the rear wall 21 of the slider 19 is also formed by the two panels 21′ arranged side by side and coplanar.
It is understood that, according to embodiments not illustrated, the rear wall 20 of the slider 19 and/or the rear wall 21 of the slider 19 could also be made by means of a single panel.

In the embodiment illustrated in
Preferably, the stop tab 25 is arranged laterally in the front wall 6, in a position proximal to the bottom wall 5 of the container 2.
Furthermore, the stop tab 26 can be glued to the front wall 42 of the slider 19.
In the closed position of the lid 4 (illustrated in
As illustrated in
By pressing on the front wall 6 of the container 2 at the stop tab 26, part of the front wall 6 of the container 2 is deformed, which pushes on the stop tab 26 so as so as to push the stop tab 26 inwards and therefore move the stop tab 26 farther away from the stop tab 25 (as illustrated in
As illustrated in
As illustrated in
The blank 32 has two longitudinal folding lines 33 (pre-weakened) and a plurality of transversal folding lines 34 (pre-weakened), which define, between the two longitudinal folding lines 33, a panel 6′ forming the wall 6 front of the container 2, a panel 5′ forming the bottom wall 5 of the container 2, a panel 7′ forming the rear wall 7 of the container 2, a panel 11′ forming the rear wall 11 of the lid 4, a panel 9′ forming the top wall 9 of the lid 4, a panel 10′ forming the front wall 10 of the lid 4, and a reinforcing flap 10″ which is folded by 180° towards the inside of the container 2 and glued against the panel 10′.
Each panel 6′ or 7′ has two lateral tabs 8′ or 8″, which are arranged on opposite sides of the respective panel 6′ or 7′, are divided from the respective panel 6′ or 7′ by the longitudinal folding lines 33, and are overlapping and glued to one another so as to form the side walls 8 of the container 2. Each flap 8″ of the panel 7′ has a tab 35 which is folded by 90° with respect to the flap 8″ and rests against the panel 5′.
Each panel 10′ or 11′ has two lateral flaps 12′ or 12″, which are arranged on opposite sides of the respective panel 10′ or 11′, are divided from the respective panel 10′ or 11′ by the longitudinal folding lines 33, and are overlapping and glued to one another to form the side walls 12 of the lid 4. Each flap 12″ of the panel 11′ has a tab 36 which is folded by 90° with respect to the flap 12″ and rests against the panel 9′.
It is important to underline that in the blank 32 the panel 11′ (i.e., the rear wall 11 of the lid 4) is permanently and firmly connected to the panel 7′ (i.e., the rear wall 7 of the container 2); consequently, during the production of the pack 1 of cigarettes it is necessary to make an incision or a clean cut on the blank 32 along a separation line in order to separate the rear wall 11 of the lid 4 from the rear wall 7 of the container 2. In other words, the blank 32 is cut along the separation line so as to completely separate the rear wall 11 of the lid 4 from the rear wall 7 of the container 2.
According to a preferred (but not binding) embodiment illustrated in
Furthermore, according to a preferred (but not binding) embodiment illustrated in
To produce the pack 1 of cigarettes described above, the packing machine described in the patent application EP1884467A1, in the Italian patent application BO2007A000039 or in the Italian patent application BO2007A000490 could be used. In these known packing machines, the slider 19 is coupled to the inner wrap 13 (and therefore folded around the inner wrap 13) before coupling the blank 32 to the inner wrap 13; according to alternative embodiments, the slider 19 can be coupled to the inner wrap 13 (and therefore folded around the inner wrap 13) before or after having coupled the collar 14 to the inner wrap 13. According to a possible alternative of known packing machines, the slider 19 is previously coupled and glued (by means of the permanent glue 41 between the stop tab 25 and the front wall 6 of the container 2) to the blank 32 and then the blank 32 together with the slider 19 (with which, at this point, forms a no longer divisible unit) is folded around the inner wrap 13 already provided with the collar 19.
According to a preferred embodiment, the fibres of the material (paper) that makes up the slider 19 must be oriented according to a direction D2 perpendicular to the sliding direction Dl (and therefore parallel to the folding line 38, parallel to the transverse edges of the container 2 and of the lid 4, and perpendicular to the longitudinal edges of the container 2 and of the lid 4). In fact, when the fibres of the material (paper) that makes up the slider 19 are parallel to the direction D2, the slider 19 flexes longitudinally less and therefore allows for a better functioning of the locking system 24 (i.e. it is more difficult that the locking system 24 does not work properly, as desired). In other words, when the fibres of the material (paper) that makes up the slider 19 are parallel to the direction D2, the slider 19 has a greater flexural stiffness in the longitudinal direction (i.e. along the sliding direction D1) and has a lower flexural stiffness in the longitudinal direction transversal direction (i.e. along the direction D2), therefore having the same stress the slider 19 deforms less longitudinally and deforms more transversely (to the advantage of the better functionality of the locking system 24).
In the embodiment illustrated in
According to an alternative embodiment, however, the button 30 is arranged in the centre of the front wall 6 of the container 2 (i.e., it is centred between the two lateral edges of the front wall 6 of the container 2).
In the embodiments illustrated in the accompanying figures, the longitudinal and transverse edges are straight; alternatively, the longitudinal and/or transverse edges could be rounded or bevelled.
In the embodiments illustrated in the attached figures, the pack 1 of cigarettes contains a group of cigarettes; alternatively, the pack 1 of cigarettes may contain any other type of smoking articles such as for example cigars, electric or electronic cigarettes (i.e., cigarettes that generate an aerosol without combustion), cartridges and refills for electronic cigarettes, new generation cigarettes.
The embodiments described herein can be combined with each other without departing from the scope of the present invention.
The above-described pack 1 of cigarettes has numerous advantages.
Firstly, the pack 1 of cigarettes described above can be classified as “child-proof”, that is, able to prevent children from opening the same. In fact, to open the pack 1 of cigarettes described above it is not enough to pull the lid 4 upwards (before rotating the lid 4) but it is necessary to exert, at the same time, a pressure on the button 30 (on the buttons 30); that is, to open the pack 1 of cigarettes described above it is necessary to carry out a particular sequence of movements which are not intuitive for a child.
Furthermore, the pack 1 of cigarettes described above, although classifiable as “child-proof”, nevertheless has relatively simple and predictable opening methods for an adult.
The pack 1 of cigarettes described above requires a not excessive amount of wrapping material as a whole, since compared to a similar rigid pack of cigarettes with a standard hinged lid it has a slightly wider collar 14 and the presence of the slider 19, which it is relatively small; consequently, compared to a similar rigid pack of cigarettes with hinged lid of the standard type, the pack 1 of cigarettes described above has an overall increase in weight of wrapping material ranging from 10 to 20%.
Finally, the pack 1 of cigarettes described above can be made in a packing machine not too different from a standard packing machine for rigid packs of cigarettes with hinged lid; consequently, the preparation of a packing machine for the production of the pack 1 of cigarettes described above does not have particularly high costs.
