- the hole 37 is arranged so that smoke can pass through the hole 37 from the first part 2 to the second part 3 , even when the capsules 4 , 5 have not been ruptured. In each of the positions shown in FIGS. 3 , 4 , and 5 , smoke may pass from the hole 40 into the hole 37 .
- the first part 2 has a substantially kidney-shaped hole 40 having two lobes. As shown in FIG. 3-5 , the two lobes are arranged to allow smoke to flow through the hole 40 , through recesses 25 , 26 and through the holes 29 , 30 (via openings 27 , 28 ) and out of the outlet openings 31 , 32 in any of the positions shown in FIG. 3 , 4 or 5 , provided that the respective capsule 4 , 5 (or both capsules) has been ruptured. This ensures that smoke will pass through the region in which flavourant is released so as to become flavoured.

Abstract
A fluid release mechanism for a smoking article comprises two longitudinally arranged parts (2,3), rotatable relative to one another from a first to a second position, a space to receive a fluid- containing member (4,5) and a contacting member (6,7) for contacting the fluid containing member in the second position, wherein the contacting member is arranged so that rotating from the first position to the second position causes relative angular movement between the contacting member and said space which causes the contacting member to enter the space for contacting and rupturing the fluid- containing member, thereby to release fluid.
Description
- This invention relates to a fluid release mechanism for a smoking article such as a cigarette.
- It is known to provide a breakable gelatin capsule containing a fluid flavourant, for example menthol, inside the plug material of a cigarette filter. When pressure is applied to the outside of the filter, the plug material surrounding the capsule presses against the capsule, thereby rupturing the capsule and releasing the flavourant. Smoke drawn from the cigarette is then flavoured by the flavourant as it passes through the filter. In this way flavour can be selectively added to the smoke drawn from the cigarette by squeezing the outside of the filter.
- The present invention provides an alternative approach for selectively modifying the characteristics of smoke.
- The present invention provides a fluid release mechanism for a smoking article, comprising first and second longitudinally arranged parts rotatable relative to one another from a first to a second position, the second part having a space to receive a fluid-containing member and the first part having a contacting member for contacting the fluid-containing member in the second position, wherein the contacting member is arranged so that rotating from the first position to the second position causes relative angular movement between the contacting member and said space which causes the contacting member to enter the space for contacting the fluid-containing member, thereby to release fluid.
- As used herein, the term “smoking article” includes smokeable products such as cigarettes, cigars and cigarillos whether based on tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes and also heat-not-burn products.
- Preferably, the fluid release mechanism is comprised in a smoking article filter, which in turn may be comprised in a smoking article. The fluid release mechanism may be arranged inside the smoking article filter so that when the fluid is released, smoke passing through the filter comes into contact with the fluid, which acts to modify the characteristics of the smoke, for example, by flavouring the smoke.
- As used herein the term fluid includes any substance which flows and therefore includes liquids, gases and solids (e.g. in powder or granule or grain form, or plastic solids) which are able to flow.
- Preferably, the fluid is a fluid flavourant. As used herein, the terms “flavour” and “flavourant” refer to materials which may be used to create a desired taste or aroma in a product. They may include extracts e.g., licorice, hydrangea, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, menthol, Japanese mint, aniseed, cinnamon, herb, wintergreen, cherry, berry, peach, apple, Dramboui, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamon, 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, coriander, coffee, or a mint oil from any species of the genus Menth a), flavour masking agents, bitterness receptor site blockers, receptor site enhancers, sweeteners e.g., sucralose, acesulfame potassium, aspartame, saccharine, cyclamates, lactose, sucrose, glucose, fructose, sorbitol, or mannitol, and other additives such aschlorophyll, minerals, botanicals, or breath freshening agents. They may be imitation, synthetic or natural ingredients or blends thereof. They may be in any suitable form, for example, oil, liquid, or powder.
- Optionally, the fluid-containing member may contain a smoke-modifying fluid other than a flavourant. For example, the fluid-containing member may contain a humectant, or liquids such as water or Vitamin A solution for filtering certain elements from the cigarette smoke
- The fluid-containing members are preferably breakable fluid-containing capsules and are further preferably formed from gelatin.
- Preferably, the fluid release mechanism comprises a restriction mechanism configured to prevent further angular movement away from the first position when the first and second parts are positioned in the second position.
- Preferably, the fluid release mechanism comprises a locating mechanism configured to locate the parts in the first position and the second position. The locating mechanism ensures that the parts are located securely in the desired position so that capsules are not accidentally ruptured by unwanted rotation of the parts caused for example by movement of the eventual cigarettes during transport or in a consumer's pocket.
- The locating mechanism may be adapted to generate an audible sound upon rotation from the first position to the second position. The audible sound provides an audible indication to the user that a capsule has been broken.
- Preferably, the fluid release mechanism is adapted to house two capsules and comprises two spaces, one for each capsule. The two parts are preferably further rotatable relative to another from the first position to a third position and the first part preferably comprises a further (second) contacting member for contacting a capsule in the third position. While rotating from the first position to the second position causes relative angular movement between the first contacting member and a first of said spaces which causes the first contacting member to enter the first space for contacting and rupturing a first of the capsules, rotating from the first position to the third position causes relative angular movement between the second contacting member and a second of said spaces which causes the contacting member to enter a second of the spaces for contacting and rupturing a second of the capsules. Preferably rotation from the first position to the second position is in the opposite direction to the rotation from the first position to the third position. For example, the direction of rotation from the first position to the second position may be clockwise and the direction of rotation from the first position to the third position may be anticlockwise. In this way, the user may selectively rupture either the first or the second capsule by twisting the filter either clockwise or anticlockwise.
- The first and second capsules may contain different flavourants for example menthol and orange essence respectively. Thus, the user may release either a menthol flavourant, an orange essence flavourant, or both flavourants.
- Optionally, the first and second capsules contain the same flavourant. In this case, the user may select the intensity of flavour by either breaking none, one or both capsules.
- Preferably, the first part is formed from moulded plastic and the second part is formed from moulded plastic.
- In order that the invention may be more fully understood, an embodiment thereof will now be described by way of illustrative example with reference to the accompanying drawings, in which:

smoking article 8 has a paper wrappedtobacco rod 13 axially aligned with filter 9. A tippingpaper 14 is wrapped around an end portion of therod 13 and the filter 9 to join them together. - The
wrappers parts wrappers - In this way, the
first part 2 of fluid release mechanism 1, thefirst rod 10, a first portion of theplugwrap 12 and a first portion of thetipping paper 14 form afirst filter segment 15 of filter 9. Similarly, thesecond part 3 offluid release mechanism 2, thesecond rod 11, a second portion of theplugwrap 12 and a second portion of thetipping paper 13 form asecond segment 16 of filter 9. - A
capsule filter parts wrappers second filter segment 16 in one direction causes thesecond part 3 of the fluid release mechanism to twist relative to thefirst part 2 so that thefirst capsule 4 is ruptured and the menthol flavourant is released. Thus, smoke drawn from the cigarette will be flavoured by the menthol flavourant as it passes through the filter. Similarly, twisting thesecond filter segment 16 in the opposite direction causes thesecond capsule 5 to be ruptured so that the orange essence flavourant is released. Thus, the menthol flavourant or the orange essence flavourant may be selectively released by either twisting the filter clockwise or anti-clockwise. Alternatively, the user may release both flavourants by first twisting in one direction, then twisting back to the original position and then twisting in the opposite direction. - As shown in
FIG. 1( a), thesecond part 3 has acylindrical body 19 and acylindrical collar 20 and thefirst part 2 has acylindrical body 21 which defines acylindrical sleeve 22 which receives thecollar 20. Referring toFIG. 2 , thesleeve 22 has an annularouter lip 23 which fits intogroove 24 which runs circumferentially around the periphery of the outer wall of thecollar 20, adjacent to thebody 19. In this way, the first and second parts can be rotated relative to one another while being held in longitudinal position by thelip 23. - As shown in
FIG. 1( a), alongitudinally extending groove 17 is formed in thebody 21 offirst part 2 and alongitudinally extending groove 18 is formed in thebody 19 ofsecond part 3. Thegrooves wrappers parts filter parts - As shown in
FIG. 1( b), thesecond part 3 has two capsule-receivingrecesses capsules recesses inner openings cylindrical holes second part 3 and defineoutlet openings FIG. 3 . - Referring to
FIG. 1( b), the second part has threerecesses bosses first part 2 in the positions illustrated inFIGS. 3 , 4 and 5. In the position illustrated inFIG. 3 , thefirst boss 6 is aligned with and received in therecess 33 and thesecond boss 7 is aligned with and received in therecess 35 and neither of thecapsules - The bosses are made from a resilient plastic so that when the
second part 3 is rotated by a user relative to thefirst part 2, thebosses recesses bosses central recess 34. Once aligned, theboss recess 34, causing a “click” sound. - As shown in
FIG. 4 , when theboss 7 is in alignment with therecess 34, theboss 6 is positioned in the capsule-receivingrecess 26. Similarly, as shown inFIG. 5 , when theboss 6 is in alignment with therecess 34, theboss 7 is positioned in the capsule-receivingrecess 25. Twisting the fluid release mechanism from the position shown inFIG. 3 to the position shown inFIG. 4 thus causes theboss 6 to be brought along an angular displacement path, into the capsule-receivingrecess 26 where it contacts, presses against and bursts thecapsule 5. Thecapsule 5 is held in position by the sidewall of therecess 26 as theboss 6 presses transversely against it. In this way, thecapsule 5 is laterally pinched between theboss 6 and the sidewall of therecess 26 until it bursts. - In a similar way, twisting the fluid release mechanism from the position shown in
FIG. 3 into the position shown inFIG. 5 brings theboss 7 along an angular displacement path into the capsule-receivingrecess 25, where it ruptures thecapsule 4. In this way, one of thecapsules FIG. 3 to either the position ofFIG. 4 orFIG. 5 . - As described above, when the
boss 6 is brought into the position ofFIG. 4 so as to rupture thecapsule 5, theboss 7 snaps into position in therecess 34, causing a “click” sound. The “click” sound provides an audible indication to the user that a capsule has been broken. Furthermore, theboss 7 is securely located in therecess 34 and thus the first and second parts will not move out of position until the user decides to twist the filter again. - Similarly, when the
boss 7 is brought into the position ofFIG. 5 so as to rupture thecapsule 4, theboss 6 snaps into position in therecess 34, thereby causing an audible indication that a capsule has been broken and securely locating theparts - The capsules may also make an audible sound when ruptured by the
bosses recess 34 and thus provides a louder audible indication for the user that a capsule has been broken. - As shown in
FIG. 1 , in addition to theholes further holes second part 3 defining twofurther outlet openings FIG. 3 , thehole 37 is arranged so that smoke can pass through thehole 37 from thefirst part 2 to thesecond part 3, even when thecapsules FIGS. 3 , 4, and 5, smoke may pass from thehole 40 into thehole 37. - As shown, the
first part 2 has a substantially kidney-shapedhole 40 having two lobes. As shown inFIG. 3-5 , the two lobes are arranged to allow smoke to flow through thehole 40, throughrecesses holes 29, 30 (viaopenings 27, 28) and out of theoutlet openings FIG. 3 , 4 or 5, provided that therespective capsule 4, 5 (or both capsules) has been ruptured. This ensures that smoke will pass through the region in which flavourant is released so as to become flavoured. - Many modifications and variations will be evident to those skilled in the art that fall within the scope of the following claims.

10. A fluid release mechanism for a smoking article as claimed in claim 9 , comprising a locating mechanism configured to locate the two parts in the first, second and third positions.
11. A fluid release mechanism as claimed in claim 10 , wherein the locating mechanism is adapted to generate audible sound upon rotation from the first position to the second position and upon rotation from the first position to the third position
12. A fluid release mechanism as claimed in any of claims 9 to 11 , wherein the first and second contacting members are resilient and the second part comprises first, second and third recesses, wherein:
the first and third recesses are adapted to receive the first and second contacting members in the first position;
the second recess is adapted to receive the second contacting member in the second position and the first contacting member in the third position;
wherein rotating from the first position towards the second position causes the second contacting member to move out of the first recess and compress against the second part, and wherein further rotation causes the compressed second contacting member to rotate until it becomes aligned with the second recess, into which it resiles so as to snap into place in the second recess, thereby causing an audible sound;
wherein rotating from the first position towards the third position causes the first contacting member to move out of the third recess and compress against the second part, and wherein further rotation causes the compressed first contacting member to rotate until it becomes aligned with the second recess, into which it resiles so as to snap into place in the second recess, thereby causing an audible sound.
13. A fluid release mechanism according to any of claims 9 to 12 , wherein rotation from the first position to the second position is oppositely directed to rotation from the first position to the third position.
14. A fluid release mechanism according to any of claims 9 to 13 , including the fluid-containing member and the further fluid-containing member.
15. A fluid release mechanism according to claim 14 , wherein the fluid contained in the fluid-containing member is a flavourant and the fluid contained in the further fluid-containing member is a flavourant.
16. A fluid release mechanism according to claims 14 or claim 15 , wherein the fluid contained in the fluid-containing member and the fluid contained in the further fluid-containing member are different fluids.
17. A fluid release mechanism according to any of claims 14 to 16 , wherein the fluid-containing member and the further fluid-containing member are fluid- containing capsules.
18. A fluid release mechanism according to any preceding claim wherein the first part is formed from moulded plastic and the second part is formed from moulded plastic.
