  1-3 show the smoking article 10 of the first embodiment. The smoking article may be a smoking article such as a cigarette, cigar or cigarillo. For convenience, these are referred to herein as “smoking articles”. The smoking article 10 includes a first portion that includes a smoking material in the form of a tobacco rod 11 with a first filter section 12 mounted thereon. The tobacco rod 11 is attached to the first filter section 12 by a cover layer, preferably chipping paper.

  The second part of the smoking article includes a cylindrical sleeve 13 extending around the tobacco rod 11 and / or the first filter section 12. The tobacco rod 11 and the first filter section 12 are configured to slide in the longitudinal direction as a unit within the sleeve 13. The tobacco rod 11 and the first filter section 12 may be referred to as a tobacco unit.

  The second portion further includes a second filter section 14 at the mouth end of the sleeve 13 remote from the first filter section 12. The second filter section 14 is firmly attached and fixed in the sleeve 13. The first and / or second filter sections 12, 14 are preferably made of conventionally used cellulose acetate tow.

  A chamber 15 is formed in the sleeve 13 between the first filter section 12 and the second filter section. The chamber 15 changes length and thus volume as the first filter section 12 slides axially within the cylindrical sleeve 13. The length of the chamber 15 varies from zero to a predetermined maximum length. Thus, the end of the sleeve 13 distal to the smoking material is movable relative to the smoking material. The first part is slidable around the second part, i.e. the second part is slidable within the first part.

  The relative movement of the first part and the second part, i.e. the sleeve 13 and the tobacco rod 11, is limited by limiting means, preferably on the abutment surface on or adjacent to the tobacco rod 11 and sleeve 13, so that the maximum length is not exceeded. Is done. In particular, the restricting means includes a first engagement surface extending radially inward from the sleeve 13 that engages a second engagement surface extending radially outward from the tobacco unit. Is possible. The second engagement surface may be formed of a sheet material wound around the tobacco unit, particularly a material (for example, chipping paper) that connects the tobacco rod and the first filter.

  FIG. 2 shows the smoking article 10 in the retracted state with the tobacco rod 11 and the first filter section 12 moved to the second filter section 14. At this time, the length of the chamber 15 is zero. That is, the length of the smoking article 10 is the shortest. The smoking article 10 may be put in a package in this stored state before use. The smoking article 10 may be returned to the stored state after use once the tobacco rod 11 has been partially or completely burned.

  FIG. 3 shows the smoking article 10 in a stretched state in which the tobacco rod 11 and the first filter section 12 have moved as far away from the second filter section 14 as possible. The length of the chamber 15 extends to the maximum. And the length of the smoking article 10 is the longest. The tobacco rod 11 and the first filter section 12 can be continuously located in the sleeve 13 so as to assume an incompletely extended position halfway between the retracted state and the extended state.

  FIG. 4 shows the smoking article 20 of the second embodiment. The smoking article 20 includes a cigarette tube 21 surrounded and attached to a sleeve 23 to form a tobacco rod. The tobacco cylinder 21 does not move relative to the sleeve. The sleeve 23 has a section 23 a extending rearward of the cigarette 21. A filter 24 is slidably disposed in the sleeve section 23a in the longitudinal direction. The chamber 25 is formed by a tubular section 23 a between the cigarette 21 and the filter 24.

  The smoking article 20 functions in the same manner as the smoking article 10. The smoking article 20 is different in that the sleeve forming the chamber 25 is attached to the tobacco rod instead of the mouthpiece filter 24. The smoking article 20 also differs in that the filter 12 is not directly attached to the cigarette 21. Other aspects of the invention may have only one of these features or differences.

  The relative movement of the sleeve 23 and the filter 24 is prevented by the limiting means so as not to exceed the maximum length. Preferably, the limiting means includes first and second engaging surfaces located at or adjacent to the sleeve 23a and filter 24, respectively. The second engagement surface may be provided by one or more sheet materials (for example, chipping paper) wound around the filter 24.

  FIG. 5 shows a smoking article 30 of the third aspect. The smoking article 30 has a structure similar to the embodiment of FIGS. 1 to 3 having a tobacco rod 31 attached to a filter 32. The tobacco rod 31 and the filter 32 are slidable within a sleeve 33 formed as a cylindrical tube. A stain binder 36 is provided at the suction end of the sleeve 33 instead of the second filter. The stain binder 36 removes substances that cause stains. A chamber 35 having a variable length is formed between the filter 32 and the stain binder 36.

  Figures 6a and 6b show a stretchable smoking article 40 of the fourth embodiment. The smoking article 40 includes a tobacco rod (not shown) attached to the first filter section 42. A sleeve 43 is attached to the first filter section 42. Located at the distal end of the sleeve 43 is a second filter section 44 which forms the mouth end. A chamber 45 is formed in the sleeve 43 between the first and second filter sections 42, 44.

  The sleeve 43 can be folded in a bellows fashion to change the length of the sleeve 43 and the chamber 45. The sleeve 43 has a plurality of sections with different diameters such that a fold line is formed with a maximum and minimum diameter line around the sleeve 43.

  In the retracted state shown in FIG. 6a, the first and second filter sections 42, 44 are pressed together so that the sleeve is compressed. The sleeve line of the sleeve 43 increases in angle and the segment of the sleeve 43 between the fold lines is oriented towards a plane perpendicular to the longitudinal axis of the smoking article. The length of the chamber 45 is relatively short.

  In the stretched state shown in FIG. 6b, the first and second filter sections 42, 44 have a reduced fold line angle of the sleeve 43 and the segment of the sleeve 43 between the fold lines is the longitudinal axis of the smoking article. To be oriented in a plane parallel to the. The length of the chamber 45 is relatively long.

  The bellows-type sleeve 43 can change the length of the chamber 45 without the need for sliding portions. Accordingly, the end of the sleeve 43 located distal to the smoking material is movable with respect to the smoking material.

  Further, as shown in FIG. 6 b, the bending state of the smoking article 40 can be adjusted by the bellows type sleeve 43. The sleeve 43 may be angled or perpendicular to the longitudinal axis so that one or more of the fold lines of the sleeve 43 do not extend uniformly along the circumference. The sleeve 43 can be bent by changing the degree of stretching along the circumference of the sleeve 43. The longitudinal axis of the first filter section 42 is not coaxial with the longitudinal axis of the second filter section 44 when the sleeve 43 is bent.

  The tobacco rod and the filter attached to it have been described as being connected by chipping paper. The chipping paper may be standard chipping paper, chipping paper provided with a relatively thick recess, or cardboard type chipping paper. Moreover, you may use the pipe | tube formed with another material in order to mount | wear a smoking material with a filter material. In particular, the tube may be made of a plastic material such as plastic made of corn starch, for example. The tube may be made of a ceramic material. The tube may be foil, metal, or metal-worked paper.

  All of the above embodiments have been described as having a filter section at the mouth end (rear) of the sleeve. Alternatively, the sleeve may not include such a filter section or stain binder. If there is no filter or stain binder at the mouth end of the sleeve, the sleeve is simply a hollow tube and the chamber is formed by the sleeve between the cigarette unit and the mouth end of the sleeve. The above-described embodiment has at least one filter section attached to one or both of the smoking material and the mouth end of the sleeve. Alternatively, the smoking article of the present invention may not include a filter section.

  One or more of these filter sections may be formed of a single segment or multiple segments of filter material. A filter section formed of a plurality of segments may include segments made of different materials or materials having different filtration performance. In particular, the filter section may comprise a standard segment consisting of cellulose acetate tow and another segment consisting of filtration material containing charcoal. Alternatively, the filter section may consist of a single segment incorporating charcoal.

  The second filter is preferably formed to assist in suction or provide other benefits associated with perception and coloring patterns. The filter may be a pressed, molded or extruded acetate.

  In another aspect of the smoking article, the chamber may include loose filter media, which is retained by a second filter or suitable means to prevent exiting the chamber. Such a loose filter medium is preferably a granular carbon that becomes a carbon particle in a broken state in the chamber.

  FIG. 7 to FIG. 21 show four modes of flavor component supply means for providing a fragrance. Any corresponding flavor ingredient delivery means may be used with any embodiment of the smoking article described in FIGS. 1-6 unless otherwise specified.

  7a to 9b show the flavor component supply means of the smoking article 50 of the first aspect. The smoking article 50 includes a chamber 55 that varies in length substantially as described in any of the above aspects. The smoking article 50 includes a tobacco unit 51 that includes only a tobacco rod and a first filter as described in FIGS. 1-3 or 5-6b or a tobacco rod as described in FIG. The tobacco rod 51 is movable at least with respect to the mouth end of the sleeve 53. The chamber 55 is formed between the tobacco unit 51 and the filter or stain binder 54. The filter or stain binder 54 is a filter 54.

  A flexible long support 57 is located in the chamber 55. The support 57 has a first end attached to the tobacco unit 51. Support 57 has a second end attached to sleeve 53 or filter 54 and attached to the mouth end of the smoking article. The support 57 is preferably in the form of a strip made of a flexible material, and particularly preferably a strip made of paper.

  The support 57 is folded when the smoking article is in the retracted state as shown in FIG. 7a or 7b. The support 57 has a plurality of folds 58 so that several sections facing each other are formed. A plurality of flavoring units 59 containing flavor component sources are bonded between opposing sections of the support 57. The flavoring unit 59 is covered by the facing section of the support 57 to prevent the flavoring from being released. The flavor component may be confined in a wrapping-like product in which a paste having a weak adhesive strength is hardened.

  8a or 8b shows the smoking article 50 in an incompletely stretched state. The cigarette unit 51 and the filter 54 are further away than when they are in the retracted state. The support 57 is stretched by reducing the fold angle. The flavoring unit 59 is divided into a first flavoring part bonded to the first surface of the support 57 and a second flavoring part bonded to the second surface of the support 57 facing the first surface. . The first part and the second part may be split and separated from each other. In this case, the first part and the second part are not restored. These detached flavor portions release flavor into the chamber 55. Apart from this, the flavoring unit 59 may release the flavoring by being exposed, that is, by being separated from the adjacent cover section of the support 57 while maintaining the overall shape without breaking.

  Moreover, you may contain a flavor component in a microcapsule. The microcapsules are formed so as to burst when the opposing surfaces of the support are separated.

  9a and 9b show the smoking article 50 in a fully extended state. The tobacco unit 51 and the filter 54 are separated from the incompletely stretched state. The support 57 is further extended by further reducing the angle of the crease 58. Since the support body 57 is not in a completely pulled state, it does not prevent or affect the extension of the smoking article 50. The flavoring unit 59 is installed along the entire length of the support 57 and diffuses and releases the flavor components over the entire length of the chamber 55.

  10a and 10b are perspective views showing the stored state and the extended state of the smoking article 50, respectively. The support 57 is made of a flexible strip-like material that can support the flavoring unit. The support 57 is preferably made of paper, and may be made of board weight. The support 57 may be formed of a metal foil piece. The flavoring unit 59 is formed as a series of points on the support 57.

  FIGS. 11-15c shows the flavor component supply means of the smoking article 60 of the second embodiment. The smoking article 60 includes a chamber 65 that varies in length as described in the above embodiment. The smoking article 60 includes a tobacco unit 61 that includes only a tobacco rod and filter as described in FIGS. 1-3 or 5-6b or a tobacco rod as described in FIG. The chamber 65 is formed between the tobacco unit 61 and the filter or stain binder 64. The filter or stain binder 64 is a filter 64.

  A long support body 67 having flexibility is located in the chamber 65. The support 67 has a first end attached to the tobacco unit 61. The support 67 extends beyond the opening of the filter 64 and has a second end outside the chamber 65 and beyond the filter 64. The support 67 is preferably a flexible thread. An enlarged portion 68 may be provided at the second end of the support 67 so that the second end of the support 67 does not exceed the filter 67. The enlarged portion 68 may be formed as a knot of the support 67.

  FIG. 11 shows the smoking article 60 in the retracted state. The support 67 extends through the filter 64, and most of the length of the support 67 is outside the chamber 65 and behind the filter 64. The support 67 is a flavoring agent, preferably coated with a wax containing a flavoring component. The flavoring agent is preferably menthol.

  FIG. 12 shows the smoking article 60 in an incompletely stretched state. The cigarette unit 61 and the filter 64 are separated from each other in the retracted state. The support 64 is pulled through the filter 64 as the smoking article is extended, and is stretched in the chamber 65. As the support is pulled through the filter 64, some of the flavoring agent coated on the support 67 is absorbed into the filter 64.

  FIG. 13 shows the smoking article 60 in a fully stretched state. The cigarette unit 61 and the filter 64 are separated from each other as compared with the incompletely stretched state. The support 67 is stretched in the chamber 65 and the enlarged portion 68 is adjacent to the filter 64. The enlarged portion 68 may be used to limit the stretching of the smoking article 60. This is because once the enlarged portion 68 abuts against the filter 64, no further stretching is possible. The chamber 65 receives a flavoring agent, particularly menthol, from the support 67.

  FIG. 14 shows a package 70 containing the smoking article 60 described above. This package includes a first compartment 71 for housing a plurality of smoking articles 60. The smoking article 60 is accommodated in the packaging container 70 in a stored state. The smoking article 60 is accommodated in a vertically extending state in the first compartment. A second compartment 72 is formed below the first compartment and is separated from the first compartment by a partition 73. The partition 73 has the opening part row | line | column 74, and each opening part 74 respond | corresponds to the position of each smoking article 60 accommodated in a 1st compartment. The second compartment 72 functions as a container having a liquid flavoring agent 75.

  Each smoking article 60 is disposed in the package 70 such that the support 67 extends downwardly through the opening 74 into the second compartment 72. Support 67 extends into the container of liquid flavorant 75. Therefore, substantially the entire support becomes wet with the liquid flavoring agent 75 in the package 70. The support 67 is preferably not initially coated with a wax having a flavor component. This is because the support 67 is immersed in the flavoring agent from the container.

  As the smoking article 60 is removed from the package 70, the support 67 extends below the filter 64 and is pulled through the opening 74. When lifting the smoking article 60, the excessively attached liquid flavoring agent 75 may flow down from the support 67. Thereafter, the smoking article 60 may be stretched as described above to introduce the flavoring agent 75 into the filter 64 and the chamber 65.

  15a, 15b and 15c show a modification of the smoking article 60. FIG. FIG. 15a shows the smoking article 60 in the stored state. The support 67 is outside the filter 64 and is spirally wound within the diameter range of the smoking article 60. FIG. 15b shows the smoking article 60 in an incompletely stretched state. A portion of the support 67 is pulled into the chamber 65 from within the helix. FIG. 15c shows the smoking article 60 in a fully extended state. The support 67 extends completely within the chamber 65 and the filter 64. The enlarged portion 68 contacts the filter 64.

  16, FIG. 17 and FIG. 18 show the flavor component supply means of the third aspect of the smoking article 80. The smoking article 80 includes a chamber of varying length formed in a sleeve 83 formed as a cylindrical tube as described in the above embodiment. The smoking article 80 includes a tobacco unit 81 that includes only a tobacco rod and filter as described in FIGS. 1-3 or 5-6b or a tobacco rod as described in FIG. The chamber is formed between the tobacco unit 81 and the filter or stain binder 84. The filter or stain binder 84 is the filter 84.

  The sleeve 83 is coaxial with the cigarette unit 81 and surrounds the end of the cigarette unit 81. The cigarette unit 81 can move in the longitudinal direction in the sleeve 83, and thereby the length of the chamber changes. The cigarette unit 81 is rotatable about the longitudinal axis with respect to the sleeve 83. As the cigarette unit 81 and the sleeve 83 rotate relative to each other, the flavoring agent is released into the chamber.

  Preferably, the sleeve is stretched and rotated independently. On the other hand, rotation and stretching may be linked. In particular, the smoking article may be stretched by rotation of the sleeve and / or the sleeve may be stretched by rotation of the smoking article.

  17 and 18 show a capsule 89 containing a flavor source that is installed in an extensible smoking article 80. The capsule is preferably a microcapsule. Capsule 89 preferably contains a menthol component or may contain another flavoring agent or substance. The capsule 89 is attached to the outer surface of the tobacco unit 81, which is the part of the tobacco unit 81 that is covered by the sleeve 83 over the entire extent of the stretched portion of the smoking article 80. A grinding means 88 is on the inner surface of the sleeve 83 in the form of one or more protrusions. The crushing means 88 extends inward from the sleeve 83 and is configured to crush the capsule 89 by rotation, whereby the flavor component is released from the capsule 89.

  The crushing means 88 has a substantially pyramid shape, and its apex is preferably directed radially inward. A plurality of grinding means 88 extend as one or more rows extending in the longitudinal direction. The plurality of rows of crushing means 88 are preferably arranged at equal intervals around the sleeve 83. The number of rows of the pulverizing means 88 is preferably four.

  Alternatively, the capsule 89 may be adhered to the inner surface of the sleeve 83, and the crushing means 88 may be attached to the outer surface of the tobacco unit 81.

  The grinding means has been described as breaking the capsule by rotating with respect to the capsule containing the flavor component. Alternatively, the grinding means may be configured to break the capsule by moving the sleeve in the longitudinal direction relative to the tobacco unit. The crushing means may be configured such that the sleeve is moved longitudinally relative to the cigarette unit and rotated to break the capsule.

  FIGS. 19 to 21 show the flavor component supply means of the fourth aspect in smoking 90. The smoking article 90 includes a chamber of varying length formed in a sleeve 83 formed as a cylindrical tube as described in the above embodiment. The smoking article 90 includes a tobacco unit 91 that includes only a tobacco rod and filter as described in FIGS. 1-3 or 5-6b or only a tobacco rod as described in FIG. The chamber is formed between the tobacco unit 91 and the filter or stain binder 94. The filter or stain binder 94 is the filter 94.

  The smoking article 90 includes one or more compartments containing a flavor component source. A compartment 99 is formed on the outer surface of the sleeve 93. The compartment 99 extends radially beyond the outer surface of the sleeve 93. Compartment 99 is separated from chamber 95 by a fragile membrane. There are preferably two such compartments on the sleeve 93. The compartments 99 are preferably located oppositely in the diametrical direction.

  The sleeve 93 may further have a window 98. The window 98 is formed of a transparent material so that the chamber 95 can be seen. It can be seen that the flavor component is introduced into the chamber 95 by the window 98.

  A radial force is applied to one or more compartments 99 to dispense the flavoring agent. A radial force is applied to the radially outward face of the compartment to break the fragile film. The flavor component can then enter the chamber 95.

  The flavoring agent is released into the chamber 95 when the smoking article 90 is in a sufficiently stretched state. When the smoking article 90 is in the stored state, the cigarette unit 91 covers the fragile membrane, so that the compartment 99 is not located in the chamber 95 space.

  In a further embodiment of the flavor component delivery means, the one or more filter portions have capsules with flavor components. The capsule may be a single-layer capsule or a two-layer capsule, and may contain other substances such as menthol or water.

  In yet another embodiment, the capsule containing the flavor component is in the chamber.

  The smoking article in all embodiments is configured to release a flavor component or to release a flavor component when stretched. On the other hand, the flavoring agent may be released separately from the stretching of the smoking article.

  You may make it change the ventilation rate of a smoking article by extending | stretching. In particular, the ventilation rate of the cigarette unit and / or sleeve may vary depending on whether or not it is covered by the cigarette unit and sleeve that are not provided with the ventilation opening. Ventilation may affect the release of flavor components and the amount of flavoring that emerges from the mouth end of the smoking article. Accordingly, the amount of flavoring agent varies with stretching.

  In any embodiment, the filter may be impregnated with a flavor component such as menthol. In all embodiments, one or both of the first filter and the second filter may be provided with a thread soaked with a flavor component. The yarn may extend substantially in the longitudinal direction, or may be arranged without a uniform orientation.

  As used herein, the terms “flavoring agent” and “flavoring ingredient” refer to a material used to impart a desired taste or scent to a product when permitted in each country. Flavoring agents or flavoring ingredients include extracts approved for use in individual jurisdictions, such as licorice, hydrangea, Japanese white bark magnesium leaf, chamomile, coloha, clove, menthol, mint, fruit, cinnamon, Herbs, wintergreen, cherry, berry, peach, apple, drunk buoy, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey extract, rose oil, vanilla, lemon Oil, orange oil, cassia, caraway, cognac, jasmine, ylang ylang, sage, fennel, pimento, ginger, anise, coriander, coffee, ah Mint oil derived from all kinds of mint genus, flavor masking agent, bitterness receptor site blocker, receptor site enhancer, sweetener (eg sucralose, acesulfame potassium, aspartame, saccharin, cyclamate, lactose, sucrose, glucose , Fructose, sorbitol or mannitol) and other additives such as chlorophyll, minerals, plants or breath deodorants. These may be imitation, synthetic or natural ingredients and may be blends thereof. These may be in any suitable shape, for example oil, liquid or powder.

  In use, all of the above-described smoking articles are preferably packaged in a stored state. In use, the user extends the smoking article by forcing the sleeve and tobacco unit apart at least in the longitudinal direction. And the user ignites the cigarette as usual. The length of the chamber is used to change the characteristics of the smoking article.

  To extinguish a smoking article, the user need only press the fired tobacco end against any suitable fire extinguishing surface. If the user has a sleeve to extinguish the cigarette, the tobacco unit is pushed into the sleeve along the longitudinal axis until the remaining tobacco unit is hidden by the sleeve. The burnt tobacco rod is therefore not visible from the side of the extinguished smoking article.

  The tobacco unit and mouthpiece filter in all embodiments may be provided separately in a packaging container. In particular, in the embodiment of FIG. 4, the mouthpiece filter may initially be separate from the remaining stretchable smoking article. The user may insert the filter longitudinally into the sleeve to complete the formation of the stretchable smoking article. By the above-mentioned suppression means, insertion in the longitudinal direction from the rear end can be performed, and then the filter cannot be pulled out.

  The filter before insertion may be individually packaged, may be packaged as a bundle, or may be particularly packaged with foil. The chipping element may be contained in a package of smoking articles, and preferably in a portion of the package separate from the smoking article.

  All features of all aspects described above can be combined with features of other aspects. In particular, any aspect of the smoking article may or may not include a filter section adjacent to the tobacco tube, and may or may not include a filter section at the mouth end of the sleeve.

The smoking article of the present invention has been described as being extensible. Apart from this, the overall length of the smoking article may be fixed. The first part may be rotatable only with respect to the second part. The flavoring agent may be released or may be released by rotation of the sleeve without changing the length of the smoking article. Further, the smoking article may have a fixed length, and the flavor component may be manually released without moving the first and second parts of the smoking article relative to each other.
