The present invention relates to a rigid box for smoking articles and to a corresponding production method.
The present invention is advantageously applied to a rigid box for a cigar to which the following description will make explicit reference without thereby losing generality.
Generally the finest cigars are individually packaged in metal tubes provided with a screw-threaded cap. Recently, a need has been felt to market fine cigars individually packaged in rigid boxes of cardboard (i.e. entirely with no metal parts). In particular, a rigid box of cardboard for a cigar must be able to provide adequate mechanical protection to the cigar itself without using an excessive quantity of packing material and must be produced with relative simplicity in a conventional automatic packing machine.
For the packaging of single cigars the use of standard type rigid boxes of cardboard has been proposed, i.e. parallelepiped shaped having four lateral walls and two end walls. Said rigid boxes of cardboard of standard type use a reduced amount of packing material and can be easily produced in a conventional automatic packing machine, but on the other hand offer a modest mechanical protection to the cigar contained inside; moreover, said rigid boxes of cardboard of standard type do not allow to house, if required, also an accessory (such as a lighter) or a gadget.
In the utility model patent ES1056319U a rigid box of cardboard for a single cigar which offers good mechanical protection to the cigar contained inside is provided; however, this rigid box requires the use of a large amount of packing material and is difficult and complex to produce in a conventional automatic packing machine (also for the fact of requiring the use of two independent blanks).
Documents DE9114788U1, DE202010009256U1, JPH02141323U, U.S. Pat. No. 306,668A, WO0146031A1 and US201130898A1 describe a rigid box comprising a panel that divides the inner volume of the rigid box in two adjacent chambers.
Documents JPH02141323U and WO0146031A1 describe that a top wall of the box has through-holes which are formed corresponding to respective chambers, leading inside the chambers, and provide access to the chambers themselves from outside the box; the presence of said through-holes facilitates viewing the articles contained inside the chambers, but on the other hand also increases the possibility that the articles could accidentally come out (and even only partially) from the chambers (for example when the box is transported for a long time in a garment pocket or in a purse or even when the box is produced in the packing machine). To limit the risk of an undesired exiting of the articles from the through-holes of the upper wall, it has been proposed to limit the size of the through-holes themselves; however, this solution greatly penalizes the functionality of the through-holes, as it much restricts the view of the articles contained in the chambers.
The object of the present invention is to provide a rigid box for smoking articles that is free from the drawbacks described above and is, at the same time, easy and inexpensive to manufacture; further object of the present invention is to provide a method for producing said rigid box for smoking articles.
According to the present invention, a rigid box for smoking articles and a respective production method are provided, as claimed in the attached claims.
The present invention will now be described with reference to the accompanying drawings, which illustrate a non-limitative embodiment, wherein:

Furthermore, the box 1 comprises a rigid panel 13, which is hinged to the panel 4 from the opposite side to the panel 5 and constitutes a pivoting lid which may cover the panel 4 itself. In other words, the pivoting lid made by the panel 13 is hinged to the panel 4 defining the upper wall to rotate with respect to the panel 4 itself between a closed position (illustrated in
According to a preferred (but not binding) embodiment, the panel 4 has (at least) one through-hole 14 which is formed at the chamber 10 so as to leading inside the chamber 10 itself, and the panel 8 has (at least) one through-hole 15 which is formed at the chamber 10 and is aligned with and superimposed on the through-hole 14. Preferably, the through-hole 15 is (slightly) larger than the through-hole 14 so that an edge of the through-hole 14 is completely contained (with a certain tolerance) within an edge of the through-hole 15; in this way the edge of the through-hole 15 is never visible through the through-hole 14 also taking into account the inevitable production and positioning tolerances of the through-holes 14 and 15 to benefit the aesthetic aspect. In other words, if the two through-holes 14 and 15 were identical in size, it would require a very high precision both in their production, and in the positioning thereof to ensure a perfect alignment between the through-holes 14 and 15; however, said high precision is difficult to achieve in a packing machine, and then (minor) misalignments would frequently occur that would expose the edge of the underlying through-hole 15 through the through-hole 14 with an extremely unpleasant effect. Said problem is completely resolved in a very simply way by making the through-hole 15 (slightly) larger than the through-hole 14.
According to a preferred (but not binding) embodiment, the panel 4 has (at least) another through-hole 16 which is formed at the chamber 11 so as to lead inside the chamber 11 itself.
The function of the holes 14, 15 and 16 is to offer from above (i.e. through the upper wall formed by the panel 4) a view (partial) of the contents of the chambers 10 and 11 (i.e. of the smoking article 2 and of the accessory 3 if present). Obviously, if one of the two chambers 10 and 11 is empty (i.e. if the accessory 3 is not present) then usually neither the corresponding hole 14 (and the respective hole 15) nor 16 is present.
The panel 4 comprises two tabs 17 (better illustrated in
According to a possible embodiment, the tabs 17 have a transverse dimension (slightly) greater than the tabs 18, so that the transverse edges of the tabs 18 are completely covered by the tabs 17; in this way the transverse edges of the tabs 18 are never visible even taking into account the inevitable production and positioning tolerances of the tabs 17 and 18 to benefit the aesthetic aspect. In other words, if the tabs 17 and 18 had identical transverse dimensions, a very high precision both in production, and in the positioning thereof would be required to ensure a perfect alignment between the corresponding transverse edges; however, said high precision is difficult to achieve in a packing machine and then (minor) misalignments would frequently occur having a particularly unpleasant aesthetic effect. Said problem is completely resolved very simply by producing the tabs 17 (slightly) larger crosswise than the tabs 18.
As illustrated in the attached figures, the edges of the panels 5 and 7 (i.e. of the lateral walls) coincide with the edges of the tabs 17 and 18 (i.e. of the front and rear walls) and therefore there is no through-opening between the edges of the panels 5 and 7 (i.e. of the lateral walls) and the edges of the tabs 17 and 18 (i.e. of the front and rear walls). According to an alternative embodiment not illustrated, the edges of the panels 5 and 7 (i.e. of the lateral walls) are spaced apart from the edges of the tabs 17 and 18 (i.e. of the front and rear walls) to define corresponding through openings between the edges of the panels 5 and 7 (i.e. of the lateral walls) and the edges of the tabs 17 and 18 (i.e. of the front and rear walls). Said result may be obtained by producing the panels 5 and 7 (i.e. the lateral walls) narrower and/or by producing the tabs 17 and 18 (i.e. the front and rear walls) narrower; in other words, to define the through openings between the edges of the tabs 17 and 18 (i.e. of the front and rear walls) and the edges of the panels 5 and 7 (i.e. of the lateral walls), the panels 5 and 7 (i.e. the lateral walls) may have a lesser longitudinal extension with respect to the panel 4 (i.e. to the top wall) and to the panel 6 (i.e. to the bottom wall) and/or the tabs 17 and 18 (i.e. the front and rear walls) may have a lesser longitudinal extension with respect to the panel 4 (i.e. to the top wall) and to the panel (i.e. to the bottom wall). The function of said through openings between the edges of the tabs 17 and 18 (i.e. of the front and rear walls) and the edges of the panels 5 and 7 (i.e. of the lateral walls) is to provide a vision (partial) of the contents of the chamber 10 and 11 (i.e. of the smoking article 2 and of the accessory 3 if present). A further function of said through openings between the edges of the tabs 17 and 18 (i.e. of the front and rear walls) and the edges of the panels 5 and 7 (i.e. of the lateral walls) is to facilitate the tear-off removal of the front and rear walls for the axial extraction of the smoking article 2 and, if present, of the accessory 3 (as will be better described hereinafter).

As illustrated in
In use, the user can examine the content of the rigid box 1 by opening the panel 13 (i.e. the lid), and then observing from above the chambers 10 and 11 through the corresponding through-holes 14, 15 and 16 (i.e. through the through-holes 14, 15 and 16 the user can see from above the smoking article 2, and if present, the accessory 3). To extract the article 2 and, if present, the accessory 3 from the corresponding chambers 10 and 11, the user generally breaks the front wall (consisting of two tabs 17 and 18 superimposed and glued one to the other) and/or the rear wall (consisting of two tabs 17 and 18 superimposed and glued one to the other) and then axially pulls out the article 2 and, if present, the accessory 3. To facilitate the breaking of the front and rear walls, the fold lines that separate said walls (i.e. the tabs 17 and 18) from the corresponding panels 4 and 6 may be pre-weakened to be easily torn-off (for example may be constituted by a succession of small, spaced apart through cuts). The tearing-off of the front and rear walls (i.e. of the tabs 17 and 18) can be facilitated by the fact that the edges of the tabs 17 and 18 (i.e. the edges of the front and rear walls) can be found at a certain distance from the edges of the panels 5 and 7 (i.e. of the lateral walls) and therefore it is simple and intuitive to put a finger between the edge of a lateral wall and the edge of the front or rear wall to pull outwards and then tear-off the front or rear one.

The methods for folding the blank 22 to produce the rigid box 1 described below, with particular reference to the blank 22 illustrated in
Initially and preliminarily, the panel 13 is superimposed and glued (by means of the glue 21) to the panel 4; this operation may be performed upstream of a packing machine which produces the rigid box 1 (i.e. before the blank 22 is fed to the packing machine), or even inside the same packing machine.
Once superimposed and glued (by means of glue 21), the panel 13 to the panel 4, the panel 6 is placed on a folding spindle 24 of a tubular and parallelepiped shape (generally hollow inside) having the same dimensions of the chamber 10 (as illustrated in
At this point, the folding spindle 24 is withdrawn axially from the chamber 10 of the rigid box 1 (i.e. the chamber 10 of the rigid box 1 is pulled axially from the folding spindle 24), and then the smoking article 2 and, if present, the accessory 3 are inserted axially into the corresponding chambers 10 and 11. Once the smoking article 2, and if present, the accessory 3 have been inserted axially in the corresponding chambers 10 and 11, the tabs 18 are folded 90° with respect to the panel 6 and, subsequently, the tabs 17 are folded 90° with respect to the panel 4 to be superimposed on the previously folded tabs 18; before this operation, between the tabs 17 and 18 glue is interposed (which may be deposited either on the tabs 17 or the tabs 18) which determines the gluing between the tabs 17 and 18 themselves. Obviously, it is possible to complete the production of the front wall or of the rear wall before inserting axially the smoking article 2, and if present, the accessory 3 in the corresponding chambers 10 and 11 and then complete the construction of the rear wall or front wall after inserting axially the smoking article 2, and if present, the accessory 3 in the corresponding chambers 10 and 11.
The rigid box 1 described above has numerous advantages.
First, the rigid box 1 described above offers very good mechanical protection to the contents (i.e. to the smoking article 2, and if present, to the accessory 3); in fact, the rigid box 1 is particularly robust due to the presence of the panel 9 which constitutes an inner reinforcement rib and thanks to the fact that the areas on which glue 19 and 20 is applied are particularly extensive (and thus guarantee a very tenacious adhesion both between the panel 4 and the panel 8, and between the panel 6 and the panel 12).
In addition, the rigid box 1 described above requires the use of a relatively modest amount of packing material. In this regard it is important to observe that the blank 22 used to produce the rigid box 1 described above and illustrated in
Finally, the rigid box 1 described above is also easy to manufacture as it can be produced in a conventional automatic packing machine; or changes to be made to a conventional automatic packing machine to produce the rigid box 1 described above are contained and substantially trivial.
