Definitions

  • the present invention concerns a tobacco article comprising a special plug wrap.
  • the tobacco article according to the invention is configured to operate with an aerosol generating device, also known as a heat-not-burn device or HNB device.
  • an aerosol generating device also known as a heat-not-burn device or HNB device.
  • Such type of aerosol generating devices is adapted to heat, rather than burn, an aerosol generating substrate comprised in the article.
  • the tobacco article according to the invention is a ready-made cigarette (RMC) comprising an aerosol generating substrate configured to release aerosol when being burnt.
  • RMC ready-made cigarette
  • a plug wrap is used to wrap one or more filter segments and has certain porosity or perforated ventilation and coefficient friction.
  • This porosity or perforated ventilation in combination with a pre-perforated tipping paper is usually needed to allow good ventilation of a stream flow passing through the filter.
  • the tipping paper is also used to ensure a filter connection to a tobacco portion of the article.
  • the tipping paper is designed to be in contact with the user's lips and defines for this purpose an appropriate roughness and design.
  • a conventional tobacco article usually defines at least a double wrap layer where each layer has its specific role. Additionally, if two or more segments are used in a filter, an individual plug wrap is necessary for each segment.
  • a combined plug wrap for combining the segments together and a tipping paper (or outermost layer of wrapper) for combining the multi-segment filter with the tobacco plug are necessary. In total, this makes three layers of wrapper. This constrains the tobacco article manufacturing process without adding substantial benefits.
  • the outermost layer of wrapper is usually designed to be in contact with the user's lips.
  • hygiene becomes more and more important for the users and additional precautionary measures to ensure hygiene may be required.
  • One of the aims of the invention is to provide a tobacco article taking an additional advantageous from at least double wrap layer structure without modifying the manufacturing process.
  • This additional advantage can be used for improving hygienic properties of the tobacco article without altering other properties of the article as the quality of the flow and aerosol released (taste, temperature, pressure drop, etc.).
  • the invention relates to a tobacco article comprising:
  • the peelable part of the tipping paper can be peeled before using the article and uncover a part of the plug wrap.
  • the plug wrap before being put in the user's mouth, does not interact with external objects or for example user's fingers.
  • a particular arrangement of the ventilation holes in respect with the peelable and fixed parts keeps unchanged the quality of the flow delivered to the user in comparison with conventional tobacco articles. Particularly, using this arrangement, it is possible to ensure a ventilation stream flow inside the filter portion as it is the case of conventional tobacco articles.
  • the plug wrap nor the tipping paper according to the invention need to be porous.
  • the plug wrap can for example be made from a material similar to the material of the tipping paper. This doesn't change the user perception of the mouth end of the article on the lips of the user.
  • the fixed part is delimited from the peelable part by a weakening line.
  • the weakening line may, for example be formed by a prescored line of the tipping paper.
  • the prescored line can be arranged fully around the circumference of the tobacco article.
  • the distance between the holes of the line can be comprised between 1 and 2 mm.
  • the width of the holes can be substantially equal to 0,5 mm. Their length can be comprised between 0,5 and 1 mm.
  • the line may be prescored by laser on the flat paper blank before it is formed into the tipping paper.
  • the prescoring can be done online or offline. According to an alternative embodiment, the line may be done using a rotating circular knife.
  • the holes of the weakening line can take various shapes. Such a shape can for example be circular, square, rectangular or a water drop shape. For example, when a laser perforation is used, a water drop shape can be formed for each hole. When a circular knife is used, a square or rectangular shape can be formed for each hole.
  • the weakening line extends circumferentially.
  • the peeling of the peelable part can be performed by the user in a simple way. Additionally, this avoids tearing of the fixed part of the tipping paper and improves the appearance of the tobacco article after removing the peelable part.
  • the ventilation holes are spaced from the weakening line.
  • the ventilation holes can extend fully through the fixed part of the tipping paper even after peeling of the peelable part.
  • the geometry and structure of the ventilation holes can be the same as in the case of a conventional cigarette. Additionally, this arrangement reduces the risk of breaking their geometry or structure when the user tears for example accidently a part of the fixed part, while peeling the peelable part.
  • the ventilation holes may be produced by laser perforation with a diameter between 100 ⁇ m and 500 ⁇ m or by electrostatic perforation for ventilation holes or smaller diameter (e.g., between 30 ⁇ m and 100 ⁇ m or smaller).
  • the ventilation holes can be advantageously smaller than the holes of the weakening line.
  • the ventilation holes are adapted to allow air entering whereas the weakening line is adapted to allow easier detaching of the peelable part.
  • the ventilation holes can have a shape which is different from the shape of the holes of the weakening line. For example, a circular shape can be used for the ventilation holes and an elongated shape (rectangular or water drop shape) can be used for the holes of the weakening line.
  • the peelable part further comprises a flap configured to be actuated to peel the peelable part.
  • the flap is preferably formed as a circumferential extension of the peelable part having a width smaller than the total width of the peelable part.
  • the flap is preferably closer to the mouth end of the filter portion than to the fixed part to facilitate handling.
  • the peelable part is adapted to be detached from the fixed part by twisting.
  • the peelable part can be detached from the fixed part by a simple and intuitive movement by the user.
  • the weakening line separating the peelable and fixed parts can be adapted to be teared upon twisting.
  • the fixed part is fixed to said surface by an adhesive layer.
  • the fixed part of the tipping paper can be firmly fixed to the plug wrap. Additionally, it is advantageous that this layer extends through the zone of this fixed part comprising the ventilation holes.
  • the adhesive layer extends from the ventilation holes to the peelable part according to a minimum distance of at least 1 mm, preferably at least 2 mm for delivering enough holding properties during tearing the weakening line. This avoids flow leakage between the tipping paper and the plug wrap so as the whole amount of the airflow passes inside the filter portion. Flow leakage can not only alter the quality of the flow inside the article but also deteriorate user experience when it is directed toward the user.
  • a preferred adhesive layer is polyvinyl alcohol (PVA) starch or copolymer based material. Its application amount to the whole surface may be around 4 mg. The viscosity of this material can be comprised between 6 500 and 8 000 cps.
  • the adhesive layer extends according to substantially the whole area of the fixed part.
  • the ventilation holes extend through the adhesive layer.
  • the peelable part is fixed to the downstream part of the plug wrap surface by at least one fixing point detachable upon peeling.
  • the peelable part can comprise a unique fixing point or a finite number of fixing points, for example two, three or four fixing points.
  • the fixing point or points are configured to break or detach during peeling of the peelable part.
  • the or each fixing point presents a low bonding strength.
  • the peelable part can be attached to the plug wrap when the article is not used and can be easily detached by the user before peeling the peelable part.
  • One or several fixing points can be arranged on an internal surface of the peelable part so as to facilitate its detachment.
  • at least one fixing point can be arranged under the flap.
  • At least one fixing point can be arranged close to the flap, for example at a distance less than 1 mm.
  • At least one fixing point can be arranged close to an edge or in the middle of the peelable part.
  • the or each fixing point can present a small dot in shape of circle not more than 1 mm of diameter.
  • the ventilation holes are formed by online laser perforation.
  • the online laser perforation device can be mounted on the cigarette making machine used to manufacture the tobacco articles according to the invention.

  • the plug wrap has at least one of the following characteristics substantially equal to the corresponding characteristic of the tipping paper:
  • the plug wrap can be similar to the tipping paper so that it can be used to interact with the user's lips and saliva after the peeling.
  • the plug wrap can comprise one or several of the above-cited characteristics of the tipping paper of the tobacco article according to the invention. In a case of a plurality of characteristics, these characteristics can be combined in any suitable manner. In a particular embodiment, the plug wrap has all of the above-cited characteristics. In this case, the plug wrap is done from the same material as the tipping paper used to form tobacco article.
  • the plug wrap has a water resistant and/or a flavour releasing coating.
  • the water resistant coating of the plug wrap can allow to the plug wrap direct interaction with the user's saliva without deteriorating its other properties.
  • the user's lips can interact directly with the plug wrap instead of the tipping paper.
  • the flavour releasing coating can allow releasing of a particular substance upon interaction with the user's lips or saliva. This substance can for example be a flavoring substance.

  • the flap 37 can for example be arranged opposite to the weakening line 35.
  • the tobacco article 10 further comprises a plurality of ventilation holes 40 arranged circumferentially and extending from the filter portion 14 through the plug wrap 22 and the fixed part 31A of the tipping paper 21.
  • the adhesive layer 32 extends through the zone of the fixed part 31A comprising the ventilation holes 40.
  • the ventilation holes 40 are preferably formed by online laser perforation extending through the plug wrap 22 and the tipping paper 21.
  • the diameter of each ventilation hole 40 can be comprised between 4 and 10 ⁇ m.
  • the online laser perforation can be performed by a device mounted on the cigarette making machine used to manufacture the tobacco article 10. In some embodiments, this device can also form the weakening line 35.
  • the ventilation holes 40 are spaced from the weakening line 35.
  • the weakening line 35 can extend parallel to the ventilation holes 40 and can be spaced from the ventilation holes 40 by a distance comprised between 5% and 70%, advantageously between 10% and 50%, of the longitudinal extension of the fixed part 31A.
  • the adhesive layer 32 comprises a part extending between the weakening line 35 and the ventilation holes 40 so as to avoid flow leakage between the plug wrap 22 and the fixed part 31A.
  • the ventilation holes 40 can be advantageously smaller than the holes of the weakening line 35.
  • the ventilation holes 40 can have a shape which is different from the shape of the holes of the weakening line 35. For example, a circular shape can be used for the ventilation holes 40 and an elongated shape (rectangular or water drop shape) can be used for the holes of the weakening line 35.
  • the user Before using the tobacco article 10 for smoking or vaping, the user can pull the flap 37 and detach the peelable part 31B from the fixed par 31A. This action will thus uncover a part of the plug wrap 22. This part can be then in contact with the user's lips during the smoking or vaping session. Since the plug wrap 22 is made from a material similar to a conventional tipping paper, the user's experience of smoking or vaping will be similar to one of a conventional cigarette or HNB article. Additionally, due to the ventilation holes 40 extending through both plug wrap 22 and tipping paper 21, the flow inside the filter portion 14 keeps the same properties as those of the flow inside a conventional cigarette.
  • the manufacturing of the tobacco article 10 according to the invention can be performed similarly to the manufacturing of a conventional tobacco article.
  • the only difference can be the material used to form the plug wrap 22.
  • the same material can be used to form the plug wrap 22 and the tipping paper 21.
