Description

ARTICLE FOR SMOKING DESCRIPTION The present invention relates to a smoking article. In particular, the invention relates to an expanded smoking article whose length can be varied to vary the length of an internal chamber.

An expandable cigar is known from US 2,820,462.

The cigar is telescopic, with a tobacco rod slidable inside a tube that has a filter at the end of the nozzle. The tobacco rod can be slid inside the tube to vary the size of an internal chamber.

US 3,062,218 discloses a telescopic cigarette in which a tobacco rod is slidable within a tube. The tube may be coated with a flavoring material, such as menthol, to provide flavor.

The present invention provides a smoking article comprising: a first part comprising a source of smoking material; a second part having at least one end configured to be movable relative to the first part and the smoking article comprising, in addition, a smoke modifying agent that can be released in the smoking article.

Therefore, the smoking article contains a smoke modifying agent, which is administered when required.

Figures 1 to 3 show a first embodiment of a smoking article (10). The article for smoking can be an article such as a cigar, cigar or cigarette. For convenience, these will be referred to as "smoking items" in this description. The article for smoking (10) comprises a first part comprising a source of smoking material in the form of a tobacco rod (11), with a first filter section fixed thereto (12). The tobacco rod (11) and the first section of the filter (12) are fixed with a covering layer, preferably formed of nozzle paper.

A second part of the article for smoking comprises a handle (13) in the form of a cylindrical tube that extends around the circumference of the tobacco rod (11) and / or the first section of the filter (12). The tobacco rod (11) and the first section of the filter (12) are sized to slide as a unit longitudinally inside the handle (13). The tobacco rod (11) and first section of the filter (12) can be referred to as a tobacco unit.

The second part may further comprise a second filter section (14) at one end of the nozzle of the handle (13) distal of the first section of the filter (12). The second section of the filter (14) is connected and fixed inside the handle (13). The first and / or second filter sections (12, 14) are preferably made of a conventional cellulose acetate tow.

A chamber (15) is defined in the handle (13) between the first filter section (12) and the second filter section (14). The chamber (15) has a variable length, and therefore volume, as the first section of the filter (12) slides axially within the cylindrical handle (13). The camera (15) has a length that varies from zero to a predetermined maximum length. Therefore, one end of the handle (13) distal to the source of smoking material is movable relative to the source of smoking material. The first part is slidable around the second part, eg. , the second part is slidable within the first part.

The relative movement of the first and second parts, eg. , handle (13) and tobacco rod (11), beyond the maximum length, is avoided with a restrictive means, preferably by abutting the surfaces in or adjacent to the tobacco rod (11) and handle (13). In particular, the restrictive means may comprise a first engaging surface extending radially inwardly from the handle (13), which meshes with a second gear surface extending radially outwardly of the tobacco unit. The second gear surface can be provided by sheet material wrapped around the tobacco unit, and in particular, by material (eg, filter paper) connecting the tobacco rod and the first filter.

Figure 2 shows the article for smoking (10) in a retracted state, with the tobacco rod (11) and the first filter section (12) moved towards the second section of the filter (13). The length of the chamber (15) has been reduced to zero. The article for smoking (10) is in its shortest overall length. The smoking article (10) can be packaged in the retracted state before use. The smoking article (10) can be returned to the retracted state after use, once the tobacco rod (11) has been partially or completely burned.

Figure 3 shows the smoking article (10) in an extended state, with the tobacco rod (11) and the first filter section (12) moved as far as possible from the second filter section (14). The length of the chamber (15) has been increased to the maximum. The article for smoking (10) is at its longest length. The smoking article (10) may be in the extended state during use. The tobacco rod (11) and the first filter section (12) are continuously positionable within the handle (13) to be in any partially extended position between the retracted and extended states.

Figure 4 shows a second embodiment of the smoking article (20). The smoking article (20) comprises a tobacco cylinder (21) surrounded by, and fixed to, a handle (13) to form a tobacco rod. The tobacco cylinder (21) does not move in relation to the handle (23). The handle (23) has a section (23a) extending rearwardly of the tobacco (21).

A filter (24) is longitudinally slidable within the section of the handle (23a). A chamber (25) is formed by the tubular section (23a) between the tobacco (21) and the filter (24).

The article for smoking (20) works in a similar manner to the article for smoking (10). The article for smoking (20) differs in that the handle forming the chamber (25) is rigidly fixed to the tobacco rod, not to the filter of the nozzle (24). The article for smoking (20) also differs by not having a filter fixed directly to tobacco (21). Yet another embodiment of the present invention may have only one of these characteristics or differences.

The relative movement of the handle (23) and the filter (24) beyond the maximum length is avoided with restrictive means. Preferably, the restrictive means comprise the first and second engaging surface at or adjacent to the handle (23a) and the filter (24), respectively. A second engagement surface may be provided by one or more layers of sheet material (eg, filter paper) wrapped around the filter (24). Figure 5 shows a third embodiment of the smoking article (30). The smoking article (30) has a construction similar to the embodiment of Figures 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 handle (33) formed as a cylindrical tube. In the handle nozzle (33) there is a stain binder (36), instead of a second filter. The stain binder (36) can remove substances that can cause stains. A variable length chamber (35) is formed between the filter (32) and the stain binder (36).

Figures 6a and 6b show a fourth embodiment of an expandable smoking article (40). The smoking article (40) comprises a tobacco rod (not shown) attached to a first filter section (42). A handle (43) is fixed to the first filter section (42). At a distal end of the handle (43) is a second filter section (44), defining a nozzle end. A chamber (45) is defined in the handle (43), between the first and second sections of the filter (42, 44).

The handle (43) can be bent into a spiral to vary the length of the handle (43) and chamber (45). The handle (43) has a plurality of sections of varying diameter, such that the bending lines are formed around the circumference of the handle (43) in the lines of maximum and minimum diameter.

In a retracted state shown in Figure 6a, the first and second sections of the filter (42, 44) are urged together, such that the handle is compressed. The lines of the handle of the handle (43) increase in angle, and segments of the handle (43) between the lines of doubling are oriented towards a plane perpendicular to the longitudinal axis of the article for smoking. The chamber 45 has a relatively short length.

In an extended state shown in Figure 6b, the first and second sections of the filter (42, 44) are urged to separate, such that the bending lines of the handle (43) reduce in angle, and the segments of the handle (43) between the doubling lines are oriented towards a plane parallel to the longitudinal axis of the smoking article. The camera (45) has a relatively long length.

The spiral handle (43), therefore, allows the chamber (45) to vary in length without requiring the parts to slide together. Therefore, one end of the handle (43) distal to the source of the smoking material is movable relative to the source of the smoking material.

As shown in Figure 6b, the spiral handle (43) also allows controlled flexing of the smoking article (40). The handle (43) may be urged at an angle or perpendicular to the longitudinal axis, such that one or more fold lines of the handle (43) are not uniformly extended around the circumference. The extension variation around the circumference of the handle (43) provides the flexure of the handle (43). The longitudinal axis of the first filter section (42) is not co-axial with the longitudinal axis of the second filter section (44) when the handle (43) is bent.

The attached tobacco rod and filter are described as connected by the filter paper. The filter paper can be standard filter paper, or a relatively thick recessed filter paper, or a cardboard filter paper. Alternatively, a tube formed of any material can fix the filter material to the source of smoking material. In particular, said tube can be made of plastic material, for example, a plastic made of corn starch. Alternatively, the tube can be made of a ceramic material. Alternatively, the tube may be formed of aluminum, metallic or metallized paper.

The above embodiments have been described as having a filter section at the end of the nozzle (rear) of the handle. Alternatively, the handle may not contain said filter section or stain binder. In the absence of a filter or stain binder at the end of the handle nozzle, the handle is only a hollow tube and the chamber is defined by the handle between the tobacco unit and the end of the handle nozzle. The above-described embodiments may have at least one filter section, fixed to one or more of the source of smoking material, and the end of the handle nozzle. Alternatively, the smoking article may not include any filter section.

One or more of the filter sections may be formed from a single segment of filter material or a plurality of segments. A filter section formed of a plurality of segments may comprise segments made of different materials or having different filtration properties. In particular, a filter section may comprise a standard segment of cellulose acetate tow and another segment of filtration material, including charcoal. Alternatively, the filter section may be a single segment incorporating charcoal.

The second filter can be shaped, preferably to help to receive strength or provide other benefits in relation to the sensation and pattern of spots. The filter can be made of compressed, formed or extruded acetate.

In yet another embodiment of the smoking article, the chamber contains loose filtration material, retained by the second filter or suitable means preventing leakage of the loose material. The loose filtration material is preferably granulated carbon, providing particles of loose carbon in the chamber.

Figures 7 to 21 show four embodiments of flavor administration systems, to provide flavorings. Any of the embodiments of the flavor administration systems may be used with any of the embodiments of the smoking article described in Figures 1 through 6, unless otherwise stated.

Figures 7a to 9b show a first embodiment of a flavor administration system in a smoking article (50). The smoking article (50) comprises a variable length chamber (55), as substantially described in any of the foregoing embodiments. The smoking article (50) comprises a tobacco unit (51), which may comprise a tobacco rod and a first filter as described with respect to Figures 1 to 3 or 5 to 6b, or only one tobacco rod as it is described with respect to Figure 4. The chamber (55) is defined between the tobacco unit (51) and a filter or stain binder (54) '. The filter or stain binder (54) will be referred to as a filter (54).

A flexible elongated substrate (57) is located in the chamber (55). The substrate has a first end attached to the tobacco unit (51). The substrate (57) has a second end attached adjacent the end of the nozzle of the smoking article, attached to the handle (53) or the filter (54). The substrate (57) is preferably a strip of flexible material, in particular, a strip of paper.

When the smoking article is in the retracted state, as shown in Figures 7a and 7b, the substrate (57) bends against itself. Preferably, the substrate (57) has a plurality of folds (58) such that the various sections of the substrate (57) face an adjacent section of substrate (57), and are in close proximity to said opposite section. Flavor units (59) containing a flavor source are fixed between the front sections of the substrate (57). Flavoring units (59) are inhibited from releasing the flavor by being covered by the front sections of the substrate (57). The flavoring source can be secured in a package joined by weak glue.

Figures 8a and 8b show the smoking article (50) in a partially extended state. The separation of the tobacco unit (51) and the filter (54) increases from the retracted state. The substrate (57) is extended by a reduction in the angle of times. Flavoring units (59) are divided into a first flavor portion fixed to a first front surface of the substrate (57), and a second flavor portion attached to a second, opposite, front surface of the substrate (57). The first and second portions can be "broken" in a non-reversible separation. The separate flavor portions release the flavors in the chamber (55). Alternatively, the flavoring units (59) can remain complete, and release the flavor upon discovery, e.g. , separated from, an adjacent coating section of the substrate (57).

Alternatively, the flavor source may be contained within microcapsules. The microcapsules are configured to be broken by the separation of the front surfaces of the substrate.

Figures 9a and 9b show the smoking article (50) in a fully extended state. The separation of the tobacco unit (51) and the filter (54) increases from the partially extended state. The substrate (57) is further extended by a further reduction in the bend angle (58). The substrate (57) is not taut, and does not inhibit or affect the spread of the smoking article (50). The flavoring units (59) are located at intervals along the entire length of the substrate (57), providing a diffuse release of flavorings over the length of the chamber (55).

Figures 10a and 10b show a perspective view of the smoking article (50) in a retracted state and an extended state, respectively. The substrate (57) can be formed of a suitable strip of flexible material, which can support the flavoring units (59). The substrate 57 is preferably paper, and may be of cardboard weight. Alternatively, the substrate (57) may be formed from a strip of metallic aluminum. The flavoring units (59) are formed as a series of spots on the substrate (59).

Figures 11 to 15c show a second embodiment of a flavor administration system in a smoking article (60). The smoking article (60) comprises a variable length chamber (65), substantially as described in any of the foregoing embodiments. The smoking article (60) comprises a tobacco unit (61), which may comprise a tobacco rod and filter as described with respect to Figures 1 to 3 or 5 to 6b, or only a tobacco rod as shown in FIG. describes with respect to Figure 4. The chamber (65) is defined between the tobacco unit (61) and a filter or stain binder (64). The filter or stain binder (64) will be referred to as a filter (64).

A flexible elongated 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 an opening in the filter (64), and has a second end outside the chamber (65) and beyond the filter (64). The substrate (67) is preferably a flexible cord. The second end of the substrate (67) can be provided with an elongated section (68) to prevent the second end of the substrate (67) from passing through the filter (64). The elongated section (68) may be formed by a knot in the substrate (67).

Figure 11 shows the 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 the chamber (65), behind the filter (64). The substrate (67) is coated with a flavoring, preferably in the form of a wax incorporating the flavor source. The flavor is preferably menthol.

Figure 12 shows the smoking article (60) in a partially extended state. The separation of the tobacco unit (61) and the filter (64) increases from the retracted state. The substrate (64) is pulled through the filter (64) as the smoking article extends, and is drawn into the chamber (65). As the substrate is pulled through the filter (64), part of the flavor coated on the substrate (67) is absorbed into the filter (64).

Figure 13 shows the smoking article (60) in a fully extended state. The separation of the tobacco unit (61) and the filter (64) increases from the partially extended state. The substrate (67) is stretched within the chamber (65) and the elongated section (68) is adjacent to the filter (64). The elongated section (68) can be used to limit the extension of the smoking article (60), because a longer extension is not possible once the elongated section (68) abuts the filter (64). The chamber (65) receives the flavor, in particular menthol, from the substrate (67).

Figure 14 shows a package (70) containing articles for smoking (60) substantially as described above. The package comprises a first compartment (71) for receiving a plurality of smoking articles (60). The smoking articles (60) are stored in the package (70) in the retracted state. The smoking articles (60) extend vertically in the first compartment. A second compartment (72) is formed vertically below the first compartment, and is separated from the first compartment by a divider (73). The divider (73) has a series of openings (74), an opening (74) aligned with the intended position of a smoking article (60) in the first compartment. The second compartment (72) acts as a reservoir containing a flavor (75) in liquid form.

Each of the smoking articles (60) are configured in the package (70) with the substrate (67) extending downwards, through an opening (74) and into the second compartment (72). The substrate (67) extends into the liquid flavor tank (75). Therefore, substantially all of the substrate is wetted by the liquid flavor (75) in the package (70). The substrates (67) are preferably not initially covered with a wax containing the flavor, because the flavor of the deposit is soaked in the substrate (67).

As a smoking article (60) is removed from the package (70), the substrate (67) extends below the filter (64) and is pulled through the opening (74). Excess liquid flavor (75) can wash the substrate (67) as the smoking article (60) is lifted. The smoking article (60) can then be extended as described, introducing the flavoring (75) in the filter (64) and the chamber (65).

Figures 15a, 15b and 15c show a variant of the smoking article (60). Figure 15a shows the smoking article (60) in a retracted state. The substrate (67) is outside the filter (64), and is coiled in a spiral, within the diameter of the smoking article (60). Figure 15b shows the smoking article (60) in a partially extended state. A portion of the substrate (67) has been pulled towards the chamber (65), from inside the spiral. Figure 15c shows the smoking article (60) in a fully extended state. The substrate (67) extends completely into the chamber (65) and the filter (64). The elongated section (68) abuts the filter (64).

Figures 16, 17 and 18 show a third embodiment of the flavor administration system in a smoking article (80). The smoking article (80) comprises a variable length chamber defined in a handle (83) formed as a cylindrical tube, substantially as described in any of the above embodiments. The smoking article (80) comprises a tobacco unit (81), which comprises a tobacco rod and a filter as described with respect to Figures 1 to 3 or 5 to 6b, or just one tobacco rod as shown in FIG. describes with respect to Figure 4. The chamber is defined between the tobacco unit (81) and a filter or stain binder (84). The filter or stain binder (84) will be referred to as a filter (84).

The handle (83) is co-axial with the tobacco unit (81), and surrounds one end of the tobacco unit (81). The tobacco unit (81) is movable in a longitudinal direction within the handle (83), to vary the length of the chamber. The tobacco unit (81) is also rotatable in relation to the handle (83) about a longitudinal axis. The relative rotation of the tobacco unit (81) and handle (83) releases the flavor in the chamber.

The extension and rotation of the handle are preferably independent. Alternatively, the rotation and extension can be linked. In particular, the rotation of the handle relative to the tobacco unit can activate the extension of the smoking article, and / or the rotation of the parts of the smoking article can activate the extension of the handle. Alternatively, the first part may be rotatable relative to the second part in a fixed longitudinal position, such that the first part is not longitudinally movable relative to the second part. The smoking article may not have any camera, such that the filter (84) abuts the tobacco unit, or the smoking article may have a camera of a fixed length.

Figures 17 and 18 show capsules (89) containing a flavor source located within the expandable cigar (80). The capsules are preferably microcapsules. Preferably, the capsules (89) contain menthol flavoring, or may contain another flavor or substance. The capsules (89) are fixed to an exterior surface of the tobacco unit (81), and preferably at a periphery of a filter fixed to a source of smoking material, or at a periphery of the source of smoking material. The capsules (89) are fixed to an outer surface of the tobacco unit (81), and preferably at a periphery of a filter attached to the source of the smoking material, or at a periphery of the source of the smoking material. The capsules (89) are in a portion of the tobacco unit (81) which is covered by the handle (83) over the entire range of extensions of the smoking article (80). The gear elements, preferably in the form of grinding elements (88), are provided on an inner surface of the handle (83), preferably in the form of one or more protrusions. The gear elements are configured to mesh with the capsules to release the flavor source. The grinding elements (88) extend inward from the handle (83) and are preferably configured to crush the capsules (89) in rotation, to release the flavor from the capsules (89).

The grinding elements (88) preferably have a substantially pyramidal shape, with an apex pointing radially inwardly. A plurality of grinding elements (88) extend in one or more rows of longitudinal extension. Preferably, a plurality of rows of grinding elements (88) are evenly spaced around the circumference of the handle (83). Preferably, there are four rows of grinding elements (88). Preferably, the grinding elements comprise a first gear surface extending at a first angle to a radial direction, and preferably, the grinding elements comprise a second gear surface extending at a second angle in a radial direction, and which encounters the first gear surface at the apex pointing radially inward. The grinding elements may comprise one or two assemblies of the first and second gear surfaces, configured to break capsules in rotation when facing them circumferentially, and / or configured to break capsules in longitudinal movement when facing them axially.

Alternatively, the capsules (89) can be fixed to the inner surface of the handle (83), and to the grinding elements (88) fixed to the outer surface of the tobacco unit (81).

The grinding elements have been described as breaking the capsules containing flavor when rotated in relation to the capsules. Alternatively, the grinding elements can be configured to break the capsules when there is relative longitudinal movement between the handle and the tobacco unit. The grinding elements may be configured to break the capsules when there is relative longitudinal movement and rotation between the handle and the tobacco unit.

Figures 19 to 21 show a fourth embodiment of the flavor administration system in a smoking article (90). The smoking article (90) comprises a variable length chamber (95) defined in a handle 8) 3) formed as a cylindrical tube, substantially as described in any of the foregoing embodiments. The article for smoking (90) comprises a tobacco unit (91), which may comprise a tobacco rod and a filter as described with respect to Figures 1 to 3 or 5 to 6b, or just one tobacco rod as it was described with respect to Figure 4. The chamber is defined between the tobacco unit (91) and a filter or stain binder (94). The filter or stain binder (94) will be referred to as a filter (94).

The smoking article (90) comprises one or more compartments containing a flavor source. The compartments (99) are formed on an exterior surface of the handle (93). The compartments (99) are formed on an exterior surface of the handle (93). The compartments (99) extend radially beyond the surface of the handle (99). A frangible membrane separates a compartment (99) from the chamber (95).

Preferably, there are two such compartments in the handle (93). Preferably, the compartments (99) are located diametrically opposite each other.

The handle (93) may further comprise a window (98). The window (98) is formed of a transparent material, allowing the view of the camera (95). The window (98) allows the flavorant to be seen when it is introduced into the chamber (95).

To dispense the flavor, a radial force is applied to one or more of the compartments (99). Radial force applied to a surface with the face radially outward of the compartment, causes the frangible membrane to break. The source of the flavor can enter the chamber (95).

The flavoring can only be released in the chamber (95) when the smoking article (90) is in a sufficiently extended state. When the smoking article (90) is in a retracted state, the tobacco unit (91) covers the frangible membranes, whereby the compartments (99) do not cover the chamber space (95).

In yet another embodiment of a flavor delivery system, one or more filter sections comprise capsules containing a flavor source. The capsules can be single capsules or double capsules, containing menthol or other substances such as water.

In yet another embodiment, the capsules containing a flavor source are in the chamber.

The smoking article of any embodiment is configured to release the flavor source, or to allow the flavor source to be released, as the smoking article extends. Alternatively, the release of the flavor may be independent of the extent of the smoking article.

Ventilation of the smoking article may depend on the extension. In particular, ventilation can be varied as the ventilation is opened in the tobacco unit and / or the handle is covered or discovered by the other tobacco and handle unit. Ventilation can affect the release of flavor, or amount of flavor that leaves the mouth end of the smoking article. Therefore, the amount of flavoring can be variable, depending on the extent.

The filter of any mode may be impregnated with a flavoring, e.g. , menthol. One or more of the first or second filters of any mode may be provided with strands impregnated with a source of flavor. The strands may extend substantially longitudinally, or may not have a uniform orientation.

As used herein, the terms "flavor" and "flavoring" refer to materials that, where allowed by local regulations, can be used to create a desired flavor or aroma in a product.

In use, an article for smoking according to any of the described embodiments is preferably packaged in a retracted state. To use it, the user extends the smoking article by separating the handle and the tobacco units in at least one longitudinal direction. The user can light tobacco in a conventional manner. The length of the chamber can be used to vary the properties of the smoking article.

To extinguish the smoking article, the user can press the end to light the tobacco against any suitable extinguishing surface. When the user holds the handle to extinguish the cigar, the tobacco unit will be moved towards the handle along the longitudinal axis until what remains of the tobacco unit is covered by the handle. The burnt tobacco rod, therefore, is not visible in a side view of the smoking article off.

The tobacco unit and the filter of the nozzle of any mode can be provided separately in a package. In particular, for the embodiments of Figure 4, the nozzle filter may initially be separated from the remnant of the expandable smoking article. The user can insert the filter longitudinally into the handle to complete the formation of the expandable smoking article. The restriction means described allow longitudinal insertion from the rear end, and prevent the filter from being pulled subsequently.

The filter can be individually wrapped or wrapped in a package before insertion, and in particular, it can be wrapped in aluminum. The tip element can be contained in the pack of smoking articles, preferably in a separate part of the package of smoking articles.

The smoking article of at least one embodiment has been described as comprising capsules. Alternatively, the flavor source can be placed in any type of encapsulation or additive release component, of which a capsule is an example. The substance in the capsules that has been selectively released has been described as a source of flavoring. The substance can be generally referred to as a smoke-modifying or additive people, of which a flavoring source is an example.

Any of the characteristics of any modality can be combined with any of the characteristics of any other modality. In particular, any of the embodiments of the smoking article may or may not have a filter section adjacent to the tobacco cylinder.

The article for smoking has been described as expandable. Alternatively, the smoking article can have a fixed length. The first part can only be rotatable in relation to the second part. The flavor may be released, or may be capable of being released, by rotating the handle 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 activated without relative movement of the first and second part of the smoking article.
