1-3 show a first embodiment of a smoking article 10. Smoking articles may be articles such as cigarettes, cigars, or cigarillos. For convenience, they will be referred to herein as "smoking articles". The smoking article 10 includes a first portion comprising a source of smoking material in the form of a tobacco rod 11, with a first filter portion 12 attached thereto. The tobacco rod 11 and the first filter part 12 are attached with a covering layer, preferably formed of tipping paper.

The second portion of the smoking article comprises a sleeve 13 in the form of a cylindrical tube extending around the circumference of the tobacco rod 11 and / or the first filter portion 12. The tobacco rod 11 and the first filter part 12 are sized to slide longitudinally within the sleeve 13 as a unit. The tobacco rod 11 and the first filter part 12 may be referred to as a tobacco unit.

The second portion may further comprise a second filter portion at the distal end of the mouthpiece of the sleeve 13, away from the first filter portion 12. The second filter part 14 is firmly attached and fixed in the sleeve 13. The first and / or second filter portions 12, 14 are preferably made of conventional cellulose acetate tow.

The chamber 15 is defined in the sleeve 13 between the first filter part 12 and the second filter part 14. The chamber 15 has a variable length and thus a variable volume as the first filter part 12 slides in the axial direction in the cylindrical sleeve 13. The chamber 15 has a length that varies from zero to a predetermined maximum length. Thus, the distal end of the sleeve 13 away from the source of smoking material may move relative to the source of smoking material. The first portion can slide around the second portion. In other words, the second portion can slide in the first portion.

Beyond the maximum length, the relative movement of the first and second parts, namely the sleeve 13 and the tobacco rod 11, is characterized by the adjacent surfaces on or adjacent to the suppression means, preferably the tobacco rod 11 and the sleeve 13 ( prevented by abutting surfaces. In particular, the containment means may comprise a first engagement surface radially inwardly extending from the sleeve 13, which may engage a second engagement surface radially outwardly from the tobacco unit. The second engagement surface may be provided by sheet material wrapped around the tobacco unit, and in particular by the material connecting the tobacco rod and the first filter (eg tipping paper).

2 shows a smoking article 10 in a retracted state with a tobacco rod 11 and a first filter portion 12 moved up to a second filter portion 13. The length of the chamber 15 is reduced to zero. Smoking article 10 is at its shortest overall length. Smoking article 10 may be packaged in a retracted state prior to use. The smoking article 10 may return to a contracted state after use, when the tobacco rod 11 is partially or fully burned.

3 shows the smoking article 10 in an extended state with the tobacco rod 11 and the first filter portion 12 moved as far as possible from the second filter portion 14. The length of the chamber 15 is increased to its maximum. Smoking articles are at their longest length. Smoking article 10 may be in an extended state during use. The tobacco rod 11 and the first filter portion 12 may be positioned continuously in the sleeve 13 to be in any partially extended position between the retracted and extended states.

4 shows a second embodiment of a smoking article 20. The smoking article 20 comprises a cylinder of tobacco 21 surrounded by and attached to the sleeve 23 to form a tobacco rod. The cylinder of cigarette 21 does not move relative to the sleeve 23. The sleeve 23 has a portion 23a extending to the rear of the cigarette 21. The filter 24 can slide longitudinally within the sleeve portion 23a. The chamber 25 is formed by a tubular portion 23a, between the cigarette 21 and the filter 24.

The smoking article 20 functions in a manner similar to the smoking article 10. The smoking article 20 differs in that the sleeve forming the chamber 25 is firmly attached to the tobacco rod rather than the mouthpiece filter 24. The smoking article 20 is also different in that it does not have a filter attached directly to the cigarette 21. Additional embodiments of the invention may have only one of these features or differences.

The relative movement of the sleeve 23 and the filter 24 beyond the maximum length is prevented by the suppressing means. Preferably, the containment means comprises first and second engagement surfaces above or adjacent each of the sleeve 23a and the filter 24. The second engagement surface may be provided by one or more layers of sheet material (eg tipping paper) wrapped around the filter 24.

5 shows a third embodiment of a smoking article 30. Smoking article 30 has a structure similar to the embodiment of FIGS. 1-3 with a tobacco rod 31 attached to filter 32. The tobacco rod 31 and the filter 32 can slide in a sleeve 33 formed of a cylindrical tube. Instead of the second filter, a stain binder 36 is at the mouthpiece end of the sleeve 33. The colored binder 36 may remove materials that may cause coloring. A variable length chamber 35 is formed between the filter 32 and the colored binder 36.

6A and 6B show a fourth embodiment of an extensible smoking article 40. Smoking article 40 includes a tobacco rod (not shown) attached to first filter portion 42. The sleeve 43 is attached to the first filter part 42. At the distal end of the sleeve 43 is a second filter portion 44, which defines the mouthpiece end. The chamber 45 is defined into a sleeve 43, between the first and second filter portions 42, 44.

The sleeve 43 can be folded like a concertina to vary the length of the sleeve 43 and the chamber 45. The sleeve 43 has a number of varying diameter portions, such that fold lines are formed around the circumference of the sleeve 43 at the maximum and minimum diameter lines.

In the retracted state shown in FIG. 6A, the first and second filter portions 42, 44 are urged to gather together, causing the sleeve to compress. The angle of the sleeve lines of the sleeve 43 is increased, and segments of the sleeve 43 between the folded lines are oriented toward a plane perpendicular to the longitudinal axis of the smoking article. Chamber 45 has a relatively short length.

In the extended state shown in FIG. 6B, the first and second filter portions 42, 44 are urged to fall, reducing the angle of the folded lines of the sleeve 43 and reducing the sleeve 43 between the folded lines. The segments of are oriented toward a plane parallel to the longitudinal axis of the smoking article. Chamber 45 has a relatively long length.

This allows the concertina sleeve 43 to vary the length of the chamber 45 without the need for components that slide against each other. Thus, the end of the sleeve 43 remote from the source of smoking material can move relative to the source of smoking material.

As shown in FIG. 6B, the concertina sleeve 43 also allows for controlled bending of the smoking article 40. Sleeve 43 may be urged at an angle perpendicular to the longitudinal axis such that one or more folded lines of sleeve 43 do not extend uniformly around the circumference. The change in extension around the circumference of the sleeve 43 provides bending of the sleeve 43. When the sleeve 43 is bent, the longitudinal axis of the first filter part 42 does not have the same axis as the longitudinal axis of the second filter part 44.

The tobacco rod and attached filter are described as being connected by tipping paper. The tipping paper may be a standard tipping paper, a relatively thick recessed tipping paper, or a board-like tipping paper. Alternatively, a tube formed of any material may attach the filter material to a source of smoking material. In particular, such a tube may be made of a plastic material, for example a plastic made from corn starch. Alternatively, the tube can be made from a ceramic material. Alternatively, the tube may be formed from foil, metal or metallized paper.

The above embodiments have been described as having a filter portion at the mouthpiece (back) end of the sleeve. Alternatively, the sleeve may not include such a filter portion or a colored binder. In the absence of a filter or colored binder at the mouthpiece end of the sleeve, the sleeve is only a hollow tube and the chamber is defined by the sleeve between the tobacco unit and the mouthpiece end of the sleeve. The embodiments may have one or more filter portions attached to one or both of the source of smoking material and the mouthpiece end of the sleeve. Alternatively, the smoking article may not include any filter portion.

One or more filter portions may be formed of a single segment or a plurality of segments of filter material. The filter part formed of a plurality of segments may include segments made of different materials or having different filtering characteristics. In particular, the filter portion may comprise a standard segment of cellulose acetate tow and an additional segment of filtration material comprising char. Alternatively, the filter portion may be a single segment comprising char.

The second filter may preferably be formed to help gain force or to provide other advantages associated with the sensory and coloring pattern. The filter can be made from compressed, molded or extruded acetate.

In a further embodiment of the smoking article, the chamber contains the unfiltered filtration material, which is maintained by a second filter or a suitable means to prevent leakage of the loose material. The loose filtration material is preferably granular carbon, which provides loose carbon particles in the chamber.

7-21 illustrate four embodiments of a flavor delivery system for providing a flavourant. Any embodiment of the flavor delivery system can be used with any embodiment of the smoking article shown in FIGS. 1-6, unless otherwise noted.

7A-9B illustrate a first embodiment of an anti-microbial delivery system in a smoking article 50. Smoking article 50 includes a chamber 55 of variable length, substantially the same as described in any of the above embodiments. Smoking article 50 includes a tobacco unit 51, which may include only a tobacco rod and a first filter as described with respect to FIGS. 1-3 or 5-6b, or a tobacco rod as described with respect to FIG. 4. Include. The chamber 55 is defined between the tobacco unit 51 and the filter or coloring binder 54. Filter or colored binder 54 will be referred to as filter 54.

A flexible stretchable substrate 57 is located in the chamber 55. The substrate 57 has a first end attached to the tobacco unit 51. The substrate 57 has a second end attached close to the mouthpiece end of the smoking article, attached to the sleeve 53 or to the filter 54. The substrate 57 is preferably a strip of flexible material, in particular a strip of paper.

As shown in FIGS. 7A and 7B, when the smoking article is in a retracted state, the substrate 57 is folded about itself. Preferably, the substrate 57 has a number of folds 58 so that some portions of the substrate 57 face adjacent portions of the substrate 57 and are in close proximity to this opposing portion. The spice unit 59 containing the source of spice is attached between facing portions of the substrate 57. The spice unit 59 is covered by the opposing portions of the substrate 57 to suppress releasing the spice. The source of flavor may be fixed in a weak glue bound parcel.

8A and 8B show smoking article 50 in a partially extended state. Separation of the cigarette unit 51 and the filter 54 increases from the retracted state. The substrate 57 is extended by the reduction of the folding angle. The spice unit 59 is separated into a first spice portion attached to the first opposing surface of the substrate 57 and a second spice portion attached to a second, opposite, opposing surface of the substrate 57. . The first and second portions may be "cracked" separately in irreversible separation. The separated spice portion releases the spice into the chamber 55. Alternatively, the flavor unit 59 may all remain and be uncovered, ie separated from the adjacent covering of the substrate 57, thereby releasing the flavor.

Alternatively, the source of flavor may be contained in the microcapsules. The microcapsules are configured to burst by separation of opposing surfaces of the substrate.

9A and 9B show smoking article 50 in a fully extended state. Separation of the cigarette unit 51 and the filter 54 increases from the partially extended state. The substrate 57 is further extended by further reduction in the angle of the folds 58. The substrate 57 is not taut and does not inhibit or affect the extension of the smoking article 50. The spice unit 59 is located at intervals along the entire length of the substrate 57 to provide a distributed release of the spice over the length of the chamber 55.

10A and 10B show perspective views of smoking articles 50 in the retracted and extended states, respectively. Substrate 57 may be formed from a suitable strip of flexible material, which may support flavor unit 59. The substrate 57 is preferably made of paper and may be made of board weights. Alternatively, substrate 57 may be formed of a metallic foil strip. The spice unit 59 is formed of a series of dots on the substrate 59.

11-15C illustrate a second embodiment of a flavor delivery system of smoking article 60. Smoking article 60 includes a chamber 65 of variable length, substantially the same as described in any of the above embodiments. Smoking article 60 includes a tobacco unit 61, which may include only tobacco rods and filters as described with respect to FIGS. 1-3 or 5-6b, or tobacco rods as described with respect to FIG. 4. . The chamber 65 is defined between the tobacco unit 61 and the filter or coloring binder 64. The filter or colored binder 64 will be referred to as filter 64.

A flexible stretchable substrate 67 is located in the chamber 65. The substrate 67 has a first end attached to the tobacco unit 61. The substrate 67 extends through the aperture of the filter 64 and has a second end outside the chamber 65 and beyond the filter 64. Substrate 67 is preferably a flexible string. An enlarged portion 68 is provided at the second end of the substrate 67 to prevent the second end of the substrate 67 from passing through the filter 64. The enlarged portion 68 may be formed by the knot of the substrate 67.

11 shows smoking article 60 in a retracted state. The substrate 67 extends through the filter 64 and most of the length of the substrate 67 is outside of the chamber 65, behind the filter 64. Substrate 67 is coated with a flavour, preferably in the form of a wax comprising a source of flavour. The flavor is preferably menthol.

12 shows smoking article 60 in a partially extended state. Separation of the cigarette unit 61 and the filter 64 increases from the retracted state. The substrate 67 is pulled through the filter 64 as it is extended, and is taut within the chamber 65. As the substrate is pulled through the filter 64, a portion of the flavor coated on the substrate 67 is absorbed into the filter 64.

13 shows smoking article 60 in a fully extended state. Separation of the cigarette unit 61 and the filter 64 increases from the partially extended state. The substrate 67 is taut in the chamber 65 and the enlarged portion 68 is adjacent to the filter 64. Since further extension is not possible if enlargement 68 is adjacent to filter 64, enlargement 68 may be used to limit the extension of smoking article 60. The chamber 65 receives a spice, especially menthol, from the substrate 67.

14 shows a package 70 that includes a smoking article 60 substantially as described above. The package includes a first compartment 71 for receiving a plurality of smoking articles 60. Smoking article 60 is stored in package 70 in a retracted state. Smoking article 60 extends vertically in the first compartment. The second compartment 72 is formed vertically below the first compartment and is separated from the first compartment by the divider 73. The divider 73 has a matrix of apertures 74, one aperture 74 in parallel with the intended position of one smoking article 60 in the first compartment. The second compartment 72 serves as a reservoir containing the liquid flavourant 75.

Each smoking article 60 is arranged in a package 70 with a substrate 67 extending downward, through the aperture 74 and into the second compartment 72. Substrate 67 extends into a reservoir of liquid flavourant 75. Thus, substantially all the substrates are moistened by the liquid flavours 75 in the package 70. Since the flavor from the reservoir wets the substrate 67, the substrate 67 is preferably not initially coated with a wax containing the flavor.

When the smoking article 60 is taken out of the package 70, the substrate 67 extends under the filter 64 and is pulled through the aperture 74. Excess liquid flavour 75 may flow from the substrate 67 when the smoking article 60 is lifted. The smoking article 60 may then be extended as described, introducing the flavor 75 into the filter 64 and the chamber 65.

15A, 15B, and 15C show a variant of smoking article 60. 15A shows smoking article 60 in a retracted state. The substrate 67 is on the outside of the filter 64 and spirally wound within the diameter of the smoking article 60. 15B shows smoking article 60 in a partially extended state. A portion of the substrate 67 is pulled into the chamber 65 from the inside of the spiral. 15C shows smoking article 60 in a fully extended state. Substrate 67 extends completely within chamber 65 and filter 64. The enlarged portion 68 is adjacent to the filter 64.

The sleeve 83 has the same axis as the tobacco unit 81 and surrounds the end of the tobacco unit 81. The cigarette unit 81 can move in the longitudinal direction in the sleeve 83 to change the length of the chamber. The tobacco unit 81 can also rotate about the sleeve 83 about the longitudinal axis. The relative rotation of the tobacco unit 81 and the sleeve 83 releases the spice into the chamber.

Extension and rotation of the sleeve is preferably independent. Alternatively, rotations and extensions can be connected. In particular, rotation of the sleeve relative to the tobacco unit may activate extension of the smoking article and / or rotation of the component of the smoking article may activate extension of the sleeve. Alternatively, the first portion may rotate relative to the second portion at a fixed longitudinal position, such as the first portion may not move longitudinally relative to the second portion. The smoking article may not have a chamber as the filter 84 is adjacent to the tobacco unit, or the smoking article may have a chamber of fixed length.

17 and 18 show capsules 89 containing a source of spices located within extensible tobacco 80. The capsule is preferably a microcapsule. Preferably, the capsule 89 may contain menthol spice, or may contain another spice or substance.

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

The grinding element has been described as breaking a capsule containing spices when rotating relative to the capsule. Alternatively, the grinding element can be configured to break the capsule in the case of relative longitudinal movement between the sleeve and the tobacco unit. The grinding element can be configured to break the capsule in the case of relative longitudinal movement and rotation between the sleeve and the tobacco unit.

19-21 show a fourth embodiment of the flavor delivery system of smoking article 90. Smoking article 90 includes a chamber 95 of variable length defined in a sleeve 93 formed of a cylindrical tube, substantially the same as described in any of the above embodiments. Smoking article 90 includes a tobacco unit 91, which may include only tobacco rods and filters as described with respect to FIGS. 1-3 or 5-6b, or tobacco rods as described with respect to FIG. 4. . The chamber is defined between the tobacco unit 91 and the filter or coloring binder 94. The filter or colored binder 94 will be referred to as filter 94.

Smoking article 90 includes one or more compartments containing a source of spices. The compartment 99 is formed on the outer surface of the sleeve 93. The compartment 99 extends radially beyond the outer surface of the sleeve 99. The fragile membrane separates the compartment 99 from the chamber 95. Preferably, there are two said compartments above the sleeve 93. Preferably, the compartments 99 are opposite to each other on opposite sides.

Sleeve 93 may further include window 98. The window 98 is formed of a transparent material that allows for viewing of the chamber 95. The window 98 is visible when the spice is introduced into the chamber 95.

In order to dispense the spice, a radial force is applied to one or more compartments 99. Radial forces exerted on the radially outward surface of the compartment break the fragile membrane. The source of spice can then enter the chamber 95.

The flavourant may be released into the chamber 95 only if the smoking article 90 is in a fully extended state. When the smoking article 90 is in a retracted state, the cigarette unit 91 covers a fragile membrane, so that the compartment 99 does not rest on the space of the chamber 95.

In a further embodiment of the flavor delivery system, the at least one filter portion comprises a capsule containing a source of flavor. The capsule may be a single capsule or a double capsule, containing other substances such as menthol or water.

In further embodiments, the capsule containing the source of flavor is in the chamber.

The smoking article of any embodiment is configured to release the source of flavour, or cause the source of spice to be released as the smoking article is extended. Alternatively, the release of the spice can be independent of the extension of the smoking article.

Ventilation of smoking articles may depend on extension. In particular, the ventilation may vary as the ventilation apertures in the tobacco unit and / or sleeve are covered or not covered by the tobacco unit and the sleeve. Gout can affect the release of the flavour, or the amount of flavourant exiting the mouth end of the smoking article. Therefore, the amount of spice can vary, depending on the extension.

Spices, such as menthol, may be injected into the filters of any embodiment. One or both of the first or second filters of any embodiment may be provided with a thread infused with a source of flavour. The thread may extend substantially in the longitudinal direction or may not have a uniform direction.

As used herein, the terms "flavour" and "flavourant" refer to substances that can be used to produce the desired taste or aroma in a product where local regulations permit. If they are acceptable by each jurisdiction, extracts such as licorice, hydrangea, Japanese white bark magnolia leaves, chamomile, fenugreek, cloves, menthol, Japanese mint, anise seed, cinnamon, herbs, presser foot grass, cherry , Berry, peach, apple, Dramboui, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon Oil, orange oil, cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, piment, ginger, anise, cilantro, coffee, or any species of the genus of genus a) Mint oils, flavor masks, bitter receptor site blockers, receptor site enhancers, sweeteners such as sucralose, acesulfame potassium, aspartame, saccharin, cyclamate, lactose, sucrose, glucose , Fructose, sorbitol, or mannitol, and other additives such as chlorophyll, minerals, botanicals, or respiratory freshening agents. These may be replicas, synthetic or natural ingredients or mixtures thereof. These may be in any suitable form, for example oils, liquids, or powders.

In use, the smoking article according to any described embodiment is preferably packaged in a retracted state. For use, the user extends the smoking article by urging the sleeve and the cigarette unit to drop at least longitudinally. The user can light the cigarette in a conventional manner. The length of the chamber can be used to change the properties of the smoking article.

To turn off the smoking article, the user can press the lit cigarette end against any suitable fire extinguishing surface. When the user grabs the sleeve to turn off the cigarette, the tobacco unit will be urged into the sleeve along the longitudinal axis until the remaining tobacco unit is covered by the sleeve. The burnt tobacco rod is therefore invisible in terms of smoking articles that have been extinguished.

The tobacco unit and mouthpiece filter of any embodiment may be provided separately within the package. In particular, for the embodiment of FIG. 4, the mouthpiece filter may be initially separated from the rest of the extensible smoking article. The user can insert the filter longitudinally into the sleeve to complete the formation of an extensible smoking article. The suppression means described allow for longitudinal insertion from the rear end and prevent the filter from later exiting.

The filters can be packaged individually or in bundles prior to insertion, in particular in foils. The tipping element may be received in the package of the smoking article, preferably in a separate part of the package for the smoking article.

Smoking articles of one or more embodiments have been described as including capsules. Alternatively, the source of flavor may be located in any form of encapsulation or additive release component, capsules of which are one example. The substances in the capsules that are selectively released have been described as sources of flavor. The material is generally referred to as a smoking control agent or additive, and the source of the flavor thereof is one example.

Any feature of any embodiment can be combined with any feature of any other embodiment. In particular, any embodiment of a smoking article may or may not have a filter portion adjacent to the cylinder of tobacco.

Smoking articles have been described as extensible. Alternatively, the smoking article may have a fixed length. The first portion may only be rotatable relative to the second portion. The flavourant may be released or may be released by rotation of the sleeve without changing the length of the smoking article.

Alternatively, the smoking article can have a fixed length and the release of the flavor can be manually operated without the relative movement of the first and second portions of the smoking article.
