Description

"ARTICLE OF THE INDUSTRY OF PRODUCTS ADAPTED TO EMIT A SUBSTANCE TO BE INHALED"
PRIORITY CLAIM
This application claims priority from Italian Patent Application No. 102017000073500 filed on June 30, 2017, the disclosure of which is incorporated by reference.
TECHNICAL FIELD
The present invention relates to an article of the industry of products adapted to emit a substance to be inhaled, in particular to an article of the tobacco processing industry (more particularly, to a smoking article) . PRIOR ART
In recent years, multi-component articles (i.e. comprising segments of different types) for the formation of aerosol have been proposed. Said articles, precisely due to the fact that they comprise a plurality of components (segments) to be managed and assembled, are complex and expensive to produce. In this regard, it is important to note that each component needs its own storage space, its own supply and an assembly device dedicated to the same. These articles have the additional drawback of needing a wide use of material and/or not always being particularly solid, since it is often difficult to guarantee an adequate and stable connection between the different components (segments) . The patent application EP3015007A1 describes a filter cigarette comprising a piece of tobacco wrapped in a first wrapping sheet and filter wrapped in a second wrapping sheet which also partially embraces the piece of tobacco so as to form a stable connection between the piece of tobacco itself and the filter. The filter internally contains several different filter pieces and, inside the filter, an empty space is also obtained which axially separates different filter pieces from one another.
The patent application US2005172976A1 describes a new generation cigarette which, in use, is electrically heated and comprises a pressed tobacco piece and a filter joined together by a wrapping sheet .
DESCRIPTION OF THE INVENTION
The object of the present invention is to provide an article of industry of products adapted to emit a substance to be inhaled, which article allows to overcome, at least partially, the drawbacks of the prior art and, at the same time, is easy and inexpensive to implement.
In accordance with the present invention, an article is provided according to what is defined in the independent claim detailed below and, preferably, in any one of the claims directly or indirectly dependent on the aforementioned independent claim.

PREFERRED EMBODIMENTS OF THE INVENTION
In the accompanying figures, 1 denotes as a whole an article for the formation of a substance to be inhaled (in particular, an aerosol) comprising a group 2 (more precisely, a row) of segments (components distinct from one another) . In particular, the article 1 is a smoking article, for example a cigarette.
The group 2 has an oblong shape (in particular, with a longitudinal axis A) and comprises a (first) segment 3 and at least a (second) segment 5 arranged in succession along a longitudinal extension (in particular, along the axis A) of the group 2.
According to some non-limiting embodiments the group 2 also comprises, at least one (third) segment 4, which is arranged in contact with the segment 3 and is interposed between the segments 3 and 5. In particular, the segments 3, 4 and 5 are arranged in succession along a longitudinal extension (in particular, along the axis A) of the group 2. The segments 3 and 5 (in particular, the segments 4 and 5) are spaced from one another so that the group 2 comprises an empty space 6 (free - that is, no segment or other structural element is arranged therein) located between the segments 3 and 5.
The article 1 furthermore comprises, a wrapping sheet 7 which is wound (rolled) around a stretch 8 and a stretch 9 of the group 2 of segments; and a wrapping sheet 10, which does not extend (is not present - is absent) to the stretch 8 and is wound (rolled) around a stretch 11 of the group 2 of segments and around the wrapping sheet 7 at the stretch 9. The wrapping sheet 7 does not extend (is not present - is absent) to the stretch 11. The stretches 8, 9 and 11 are arranged (in succession) along said longitudinal extension (more precisely, along the longitudinal axis A) .
The particular arrangement of the sheets 7 and 10 allows the article 1 to be stable from a mechanical point of view, using at the same time a reduced quantity of material and/or a reduced number of components.
More precisely, the wrapping sheet 7 is wound (rolled) around (and in contact with) the stretches 8 and 9 at least once (at least one complete revolution - at least by 360°), in particular so that the stretches 8 and 9 are laterally completely covered. In other words, the lateral surface of the stretches 8 and 9 (that is, the surfaces delimiting the stretches 8 and 9 radially to the axis A towards the outside - typically, said surfaces extend parallel to the axis A) are (completely) covered (wrapped) by the sheet 7.
More precisely (similarly to what has been said for the sheet 7), the sheet 10 is wound (rolled) around the stretch 11 of the group 2 of segments and around the wrapping sheet 7 at the stretch 9 at least once (at least one complete revolution - at least by 360°), in particular so that the stretch 11 and the sheet 7 at the stretch 9 are laterally completely covered. In other words, the lateral surface of the stretch 11 and of the sheet 7 at the stretch 9 (that is, the surfaces that delimit the stretch 11 and the sheet 7 radially to the axis A towards the outside - typically said surfaces extend parallel to the axis A) are covered (wrapped) by sheet 10. More generally, advantageously but not necessarily, when in the present text it is stated that a sheet is wound around something (a segment, a stretch and/or a part of a segment) means that the sheet is wound at least once (360°) around said thing .
In particular (therefore), the sheets 7 and 10 are wound around the group 2 (at least once) so as to define, for each, a respective tubular shape.
Advantageously but not necessarily, the article 1 has, furthermore, at least two wrapping layers 12 and 13, which are at least partially defined by the wrapping sheet 7 and/or 10 and are wound around the empty space 6 (around the entire space 6) so as laterally (completely) delimit it (peripherally - radially relative to the longitudinal extension of the group 2, more precisely relative to the axis A) . According to some non-limiting embodiments (see Figures from 5 to 7), the article 1 has (at least) three wrapping layers 12, 13 and 14, which are at least partially defined by the wrapping sheet 7 and/or 10 and are wound around the empty space (around the entire space 6) so as to laterally (completely) delimit it (peripherally - radially relative to the longitudinal extension of the group 2, more precisely relative to the axis A) .
In particular, the layers 12 and 13 (and possibly 14) extend from a first end (delimited by the segment 4) to a second end (delimited by the segment 5 or 15) of the space 6.
The layers 12 and 13 (and possibly 14) are meant to be wound (at least) once (at least by 360°) around the space 6 (as they are laterally delimiting the space 6 itself) . The presence of a plurality of external layers at the empty space 6 allows to give the article 1 a sufficient mechanical strength even in the absence of segments (or other elements which have - also - a structural function) at the space 6. The absence of further segments (or other elements that have - also - a structural function) between the segments 4 and 5 leads to a simplification of the production of the article 1, being, inter alia, necessary to manage (store, feed and/or or assemble) an element less than would otherwise be necessary.
Advantageously but not necessarily, the stretch 8 comprises (at least part of) the segment 3. In addition or alternatively, the stretch 11 comprises (at least part of) the segment 5. Alternatively or additionally, the stretch 9 comprises (at least part of) the segment 3 (and/or 5) . Alternatively or additionally, the stretch 9 comprises (at least part of) the segment 4. Alternatively or additionally, the stretch 9 comprises (at least part of) the empty space 6. According to some non-limiting embodiments, the group 2 comprises at least one further segment 15, which is arranged between the segments 3 and 5 (in particular, between the segments 4 and 5) in contact with the segment 5. In these cases, the empty space 6 is arranged between the segments 4 and 15. The wrapping sheet 10 is wound (at least once) (also) around the (at least part of) the segment 15 (in this way the segments 15 and 5 are kept integral one with the other) .
The empty space 6 is (therefore) delimited at the ends by the segments 3 (or possibly 4) and 5 (or possibly 15) .
According to some non-limiting and not illustrated embodiments, the segment 4 has its own through cavity, which extends in the direction of the longitudinal extension of the group of segments (in particular, in the direction of the axis A) . In addition or alternatively, the segment 15 is provided with its own through cavity which extends in the direction of the longitudinal extension of the group of segments (in particular, in the direction of the axis A) . According to specific and non-limiting embodiments, the segment 4 (and possibly the segment 15) is made of cellulose acetate, more precisely it is paperless (NWA - non-wrapped acetate) . Advantageously but not necessarily, at least one of the segments 3 and 5 and possibly 4 (in particular, the segment 3) is adapted to release the substance to be inhaled. According to some non-limiting embodiments, the segment adapted to release the substance to be inhaled comprises the tobacco. In particular, the segment 3 is adapted to release the substance to be inhaled.
Advantageously but not necessarily, at least one of the segments 3 and 5 and possibly 4 comprises (is made of) filtering material. In particular, the segment 5 comprises (is made of) a filtering material.
According to some non-limiting embodiments (see for example Figure 4), the article 1 comprises a further wrapping sheet 18, which is wound (at least once) around the empty space 6, in particular so as to define at least one among the wrapping layers 12 and 13 (and possibly 14) laterally delimiting the empty space. In particular, the wrapping sheet 18, which is wound (at least once) around at least part of the segment 4.
Advantageously but not necessarily, the sheet 18 is also rolled around at least part of the segment 15 (where present) .
More precisely (similarly to what has been said for the sheet 7 and for the sheet 10) , the sheet 18 is wound (rolled) around the empty space 6 (and possibly around at least part of the segment 4, in some cases, the sheet 18 is wound - rolled - around at least part of the segment 15) at least once (at least one complete revolution - at least by 360°), in particular the space 6 (and possibly at least part of the segment 4 - and/or the segment 15) is laterally completely covered .
According to some non-limiting embodiments (Figures 1-8), the sheet 10 is wound around (at least part of) the segments 4 and 5 (at least once) . In this way the segments 4 and 5 are integral one with the other. In addition or alternatively (Figures 5, 6, 8 and 9) , the sheet 10 is wound around (at least part of) the segments 3 and 5 (at least once) . In this way the segments 3 and 5 are integral one with the other. In addition or alternatively (Figures 1-7), the sheet 7 is wound (at least once) around (at least part of) the segments 3 and 4. In this way the segments 3 and 4 are integral one with the other . According to some non-limiting embodiments, the sheets 7 and 10 (and possibly 18) are made of paper or cardboard or similar material (in particular, a non-rigid material which allows the sheets to be rolled up but, at the same time, allows a sufficient structural strength) . In addition or alternatively, the layers 12 and 13 (and possibly 14) are made of paper or cardboard or similar material (in particular, a non-rigid material which can be rolled up but, at the same time, allows sufficient structural solidity) . Advantageously but not necessarily, the stretch 9 comprises (at least part of) the empty space 6. In this way a particularly resistant connection between the segments 3 and 4 on one side and the segment 5 (and possibly 15) on the other is obtained and a good mechanical seal in the area of the space 6. Advantageously but not necessarily (Figures 1 and 8) the sheet 10 is wound at least twice (at least 720° - see, in particular, Figures 2 and 3) around the empty space 6, in particular so as to define the two wrapping layers 12 and 13. Advantageously but not necessarily, the sheet 10 is wound at least twice (at least 720° - see, in particular, Figures 2 and 3) around the segment 5 (and possibly around the segment 15) .
In addition or alternatively, according to specific embodiments, such as that illustrated in Figures 1-3, the sheet 7 is wound (at least once) around the segment 3 (and around the segment 4) (and does not extend to the space 6 and to the segments 5 and 6) and the sheet 10 is wound (at least once, more precisely, at least twice) around the segment 5 (around the segment 15) (and around at least part of the segment 4) .

Advantageously but not necessarily (Figures 5-7), the sheet 10 is wound at least once (at least by 360°) around the sheet 7 at the empty space 6, in particular so as to define at least one wrapping layer 11 or 12 (or 13) laterally delimiting the empty space. In these cases, the mechanical stability of the article 1 is particularly relevant.
According to some non-limiting (and not illustrated) embodiments, the sheet 10 is wound at least twice (at least by 720°) around the sheet 7 at the empty space 6, in particular so as to define at least two of the wrapping layers 11, 12 and 13 laterally delimiting the empty space.
Advantageously but not necessarily (Figures 5-7), the wrapping sheet 7 is wound at least twice (at least by 720°) around the empty space 6, in particular so as to define at least two of the wrapping layers 12, 13 and 14.
According to specific embodiments, such as that illustrated in Figure 5, the sheet 7 is wound (at least twice) around the segment 3, the segment 4, the space 6 and the segment 15 (and is absent at the segment 5) and the sheet 10 is wound around the segment 5, the segment 15, the segment 4, the space 6 and part of the segment 3. In particular, the sheet 7 extends up to an end of the segment 5 facing the segment 4 (and in contact with the segment 15) .
According to specific embodiments, such as that illustrated in Figure 6, the sheet 7 is wound (at least twice) around the segment 3, the space 6 and the segment 4 (and is absent at the segment 5) and the sheet 10 is wound around the segment 5, the space 6, the segment 4 and part of the segment 3. In particular, the sheet 7 extends up to an end of the segment 5 facing the segment 4. According to specific embodiments, such as that illustrated in Figure 7, the sheet 7 is wound (at least twice) around the segment 3, the space 6 and the segment 4 (and is absent at the segments 5 and 15) and the sheet 10 is wound around the segment 5, the segment 15, the space 6 and part of the segment 4 (and is absent at the segment 3) . In particular, the sheet 7 extends up to an end of the segment 15 opposite to the segment 5.
Advantageously but not necessarily, the wrapping layers 12 and 13 (and possibly 14) have a plurality of through holes (of a known type and not illustrated) , which establish a connection between the empty space 6 and the outside. In particular, the holes are distributed along the peripheral extension of the wrapping layers 12 and 13 (and possibly 14) . In particular, the holes are distributed in rows (and are radially orientated relative to the axis A) .
The holes can eventually be made by means of a laser.
The article 1 of the present invention has a remarkable mechanical stability and can be produced in a simple and inexpensive way.
