Definitions
- the present invention relates to a smoking article constructed by wrapping a filter main body with a sheet and a filter used for the smoking article.
- Filters for cigarettes are usually produced by wrapping a filtering material such as cellulose acetate tow with wrapping paper.
- filters containing adsorbent particles, such as activated carbon, or containing flavor enhancer particles for supplementing tobacco flavor are generally known.
- Known methods of adding the particles are roughly classified into two types of a Dalmatian type in which particles are dispersed in a filter material such as cellulose acetate tow, and a cavity type in which a cavity part is formed between filters and particles are added to the cavity part.
- spherical activated carbon as an adsorbent is added to a cavity part as a measure for an improvement in the packing ratio of activated carbon and as a countermeasure against contamination of machines.
- adding a flavor enhancer include the following: In Jpn. PCT National Publication No. 2010-521962 , cellulose particles containing flavor are added to a cavity portion, and in Jpn. PCT National Publication No. 2007-520204 , a breakable capsule is added to a cavity portion.
- U.S. Patent No. 6,537,186 discloses a method for manufacturing a cavity filter.
- Jpn. Pat. Appln. KOKAI Publication No. 2008-48734 discloses a gluing method at the time of production of a continuous body of articles in the tobacco processing industry.
- Japanese Patent No. 4955866 discloses a method of applying an adhesive to a covering paper tape.
- a smoking article is desired that not only is adhered correctly at the time of manufacture but also maintains sufficient adhesive strength even after a predetermined time has elapsed.
- a smoking article comprising: a filter main body that is cylindrical; a sheet that forms a cylindrical body having one end portion and another end portion opposite to and overlapping the one end portion to wrap the filter main body; a first hot melt type adhesive and a first aqueous adhesive provided at a position between the filter main body and the sheet; and a second hot melt type adhesive and a second aqueous adhesive provided at a position between the one end portion and the other end portion.
- the smoking articles include a cigarette, a smoking tool to inhale flavor of tobacco by electronic device heating, a carbon heat source, or the like, and a non-heating type smoking tool to inhale flavor of tobacco.
- a cigarette 11 has a cylindrical tobacco portion 12, a cylindrical filter portion 13 provided adjacent to the tobacco portion 12, and a tipping paper 14 covering the tobacco portion 12 and the filter portion 13.
- An end portion of the filter portion 13 constitutes a suction opening 13A, and the suction opening 13A is positioned in the oral cavity of a smoker when it is put in lips of the smoker.
- the tobacco portion 12 is formed by wrapping the periphery of the shredded leaves 15 (tobacco) with a wrapping paper 16.
- the filter portion 13 includes a first filter main body 21 (filter main body) located on the side of the suction opening 13A, a second filter main body 22 provided separately from the first filter main body 21 in the central axis C direction and located on the tobacco portion 12 side, a cylindrical outer wrapper 23 (sheet) covering the first filter main body 21 and the second filter main body 22, a cavity 24 (cavity) provided between the first filter main body 21 and the second filter main body 22, granules 25 contained in the cavity 24, the tipping paper 14, and a plurality of openings (ventilation holes) 36 for taking in outside air.
- the outer wrapper 23 (sheet) has a rectangular shape in a state not bonded with an adhesive. As shown in FIG. 2 , the outer wrapper 23 has one end portion 26 and the other end portion 27 opposite thereto. The outer wrapper 23 is adhered so that the one end portion 26 overlaps the other end portion 27 so as to form a cylindrical shape and to wrap the first filter main body 21 and the second filter main body 22 inside thereof. When the outer wrapper 23 becomes cylindrical, the one end portion 26 is arranged inside the other end portion 27.
- an overlap portion 29 a position at which the other end portion 27 overlaps the one end portion 26 is referred to as an overlap portion 29.
- the outer wrapper 23 is formed as a transparent paper sheet and a transparent film. More specifically, the outer wrapper 23 is made of a paper having high transparency such as glassine paper or paraffin paper, a cellophane film made from wood pulp as a raw material, or a plastic-based transparent film such as polypropylene (PP), polyethylene (PE) polymethyl methacrylate (PMMA), polystyrene (PS), or polyethylene terephthalate (PET). Furthermore, the outer wrapper 23 may be formed of opaque general paper. The outer wrapper 23 may have air permeability or may not have air permeability.
- FIG. 2 shows a sectional view taken along the line F2-F2 of FIG. 1 (in FIG. 2 , the tipping paper is omitted).
- the filter portion 13 further includes a first hot melt type adhesive 31 provided at a position between the first filter main body 21 and the outer wrapper 23 (and between the second filter main body 22 and the outer wrapper 23), a second hot melt type adhesive 32 provided at a position (overlap portion 29) between the one end portion 26 and the other end portion 27 of the outer wrapper 23, a first aqueous adhesive 33 provided at a position between the first filter main body 21 and the outer wrapper 23 (and between the second filter main body 22 and the outer wrapper 23), and a second aqueous adhesive 34 provided at a position (overlap portion 29) between the one end portion 26 and the other end portion 27.
- the first aqueous adhesive 33 and the second aqueous adhesive 34 are continuous and integrally formed.
- the aqueous adhesive is provided across the position between the first filter main body 21 (the second filter main body 22) and the outer wrapper 23, and the position between the one end portion 26 and the other end portion 27 (overlap portion 29).
- adsorbent particles activated carbon or the like which partially adsorb and remove the tobacco smoke component and flavor enhancer particles can be used. Both adsorbent particles and flavor enhancer particles can be mixed and filled in the cavity 24.
- the first filter main body 21 and the second filter main body 22 each have a columnar shape formed by wrapping fibrous filler material 37 with a wrapper 35.
- the first filter main body 21 and the second filter main body 22 can be formed by various kinds of filler material 37.
- these are constituted of the filler material 37 of a cellulose-based semisynthetic fiber such as cellulose acetate, for example, but the filler material 37 is not limited thereto.
- the filler material 37 include plant fibers such as cotton, hemp, Manila hemp, palm, rush and the like, animal fibers such as wool and cashmere, cellulose-based regenerated fibers such as rayon, synthetic fibers such as nylon, polyester, acrylic, polyethylene, polypropylene, or a combination thereof.
- the constituent elements of the first filter main body 21 and the second filter main body 22 may include granular substances of adsorbent particles and flavor enhancer particles in addition to the filler material made of the above cellulose acetate fibers.
- the first filter main body 21 and the second filter main body 22 may have a multi-segment structure in which two or more different types of segments are connected in the axial direction. In that case, each segment is wrapped with the wrapper 35 so that its position in the first filter main body 21 and the second filter main body 22 is fixed.
- the filler material 37 may be wrapped with a segment wrapper, or a non-wrap filter as shown in FIG. 15 of Japanese Patent No. 4262247 may be used.
- a plasticizer and a binder may be added to the first filter main body 21 and the second filter main body 22 in order to obtain a desired hardness of the filter.
- Any type of plasticizer may be used.
- the plasticizer include triethyl citrate, acetyl triethyl citrate, acetyl tributyl citrate, dibutyl tartrate, ethyl phthalyl ethyl glycolate, methyl phthalyl ethyl glycolate, triacetin, triethyl phosphate, triphenyl phosphate, tripropionine, or a combination thereof.
- Any type of binder may be used.
- HMC, HPMC, PVA, PVAc, PEG, or a combination thereof may be used.
- plasticizers and binders may not be used.
- first filter main body 21 and the second filter main body 22 may contain flavor such as menthol.
