Description

Technical field

The present invention relates to a component of a tobacco industry product and to a tobacco industry product containing this component. The present invention also relates to a method for manufacturing a tobacco product component.

State of the art

Flavored cigarettes are known in the art. During use, the user may break the capsule to release the flavor into the smoke passing through the cigarette. Therefore, the user can selectively add flavor to the smoke.

The essence of the invention

SUBSTANCE: proposed is a component of a product of the tobacco industry, containing: a wall bounding a cavity; capsules with an additive placed in the cavity; and particles located in the cavity, when using the product, contribute to the destruction of capsules with the additive when an external force is applied to the wall of the component of the tobacco industry product by the user, and the particles contain a material with a particle density of at least 1 g/cm ³ .

The particles may contain a plasticizer. In one embodiment, the plasticizer contains triacetin.

In one embodiment, the particles comprise a polymeric material and preferably a plastic.

In one embodiment, the particles contain cellulose acetate. In one embodiment, the particles comprise cellulose acetate flakes.

In one embodiment, the particles contain one or more surface formations that promote the destruction of capsules with the additive.

In some embodiments, the particles are optionally formed from a material with a Rockwell hardness of at least 25 Rockwell when measured in accordance with ASTM D ₇₈₅ .

Preferably the particles are formed from a material with a Rockwell hardness of at least 30 or at least 40 or at least 50 or at least 60 or at least 70 or at least 80 or at least 90 or at least 100 on the Rockwell scale when measured in accordance with ASTM D ₇₈₅ .

In one embodiment, the particles have an average surface area of less than 50 m ² /g and preferably less than 30, 20, 10, 5 or 3 m ² /g. The surface area can be measured according to standard ASTM D ₁₉₉₃ -18 (Standard Test Method for Precipitated Silica -Surface Area by Multipoint BET Nitrogen Adsorption, ASTM International, West Conshohocken, PA, 2018) (Standard test method for surface area of the precipitated silica by BET analysis of nitrogen uptake at several points). Particle density can refer to the material density of particles containing pores in the material, but excluding voids between particles (otherwise it would be "bulk density").

It has been found that the smaller the surface area of the particles, the stronger the particles are, which may be due to the lower porosity of the particles. Stronger particles tend to break the additive capsules when an external force is applied to the wall of the tobacco product component. The stronger particles also help prevent capsule breakage during transit. In addition, it has been found that less surface area means that the particles absorb less additive from the additive capsules as they break, and this results in more additive that can be delivered to the user.

The particles contain a material with a particle density of at least 1 g/cm ³ , which makes the particles stronger and contributes to the destruction of the additive capsules during use of the product and prevents the particles from breaking during transportation. In some embodiments, the implementation of the particles contain material with a particle density of at least 1.1 g/cm ³ or at least 1.2 g/cm ³ and increasing the density of the particles increases their strength.

In one embodiment, the particles contain material with a particle density of less than 5 g/cm ³ and preferably less than 2 g/cm ³ or less than 1.5 g/cm ³ . The lower particle density results in a lighter tobacco product component that is easier to transport.

In some embodiments, the particle density is 1 to 2 g/cm ³ , or 1.1 to 2 g/cm ³ , or 1.1 to 1.5 g/cm ³ .

In one embodiment, the supplement capsules are 0.6 to 1.4 mm in diameter, and preferably about 1 mm in diameter.

In one embodiment, the particles are 1 to 2.4 mm in size, and preferably 1.4 to 2 mm.

In some embodiments, the particles are substantially cylindrical in shape. The particles can be obtained from the material made by extrusion of the rod and cut into individual essentially cylindrical particles.

In some embodiments, the particles have a drop hardness greater than 95%, and preferably greater than 96 or 97 or 98 or 99%. In some embodiments, the impact hardness of the particles may be greater than 99.5, 99.6, 99.7, 99.8, or 99.9%. Particle drop hardness can be measured using the hardness tests described in ASTM D ₃ 802-16 (Standard Test Method for Ball-Pan Hardness of Activated Carbon, ASTM International, West Conshohocken, PA, 2016) (Standard Method hardness testing of activated carbon by the falling head method). These tests are described for testing the hardness of activated carbon. However, they are also suitable for measuring the hardness of other particulate materials. Increasing the hardness of the particles has been found to make them stronger and therefore more effective in promoting breakage of additive capsules during use of the article, and also results in less chance of breakage of the particles during transport.

The tobacco product component may contain 20 to 100 additive capsules, and preferably 40 to 80 additive capsules.

In some embodiments, the additive capsules have an average tensile strength of 3 to 5 N, and preferably 3.5 to 4.5 N. In some embodiments, the additive capsules have an average tensile strength of about 4 N. crush strength) is the force required to break a single additive capsule.

In one embodiment, the cavity has a length of 4 to 12 mm, and preferably 6 to 10 mm.

In one embodiment, the tobacco product component component includes a filter material body that includes a cavity, and preferably the body comprises first and second sections of filter material, with the cavity located between the first and second sections.

The tobacco product component may further comprise a ficell that surrounds the cavity. Ficella may contain an impervious coating, for example a coating that is impermeable to the additive from the additive capsule. In some embodiments, the ficell has a basis weight of at least 60 g/m ² . In some embodiments, the ficell is at least 35 microns thick.

In one embodiment, one or more supplement capsules comprise an outer shell and an inner content. The internal content may be a fluid. The internal contents may be liquid. The outer shell may be a hard outer shell. The outer shell may contain alginate.

In one embodiment, the tobacco product component further has an outer surface containing an indicator configured to indicate to the user where an external force should be applied to the smoking article component.

In some embodiments, the tobacco product component includes a smoking product component, such as a filter.

Also provided is a tobacco industry product comprising a tobacco industry product component of the present invention.

In some embodiments, the tobacco industry article includes a smoking article.

Also proposed is a component of the tobacco industry product, containing: a wall that defines the cavity; capsules with an additive placed in the cavity; and particles located in the cavity, when used, contribute to the destruction of the capsules with the additive when the user applies an external force to the wall of the product component. In some embodiments, the particles are cellulose acetate particles. The tobacco product component may have any of the features described above, including optionally that the particles contain material with a particle density of at least 1 g/cm ³ , although this feature is not essential.

Detailed description

In FIG. 1-6 show an embodiment of tobacco product 1. In the present embodiment, tobacco product 1 is smoking product 1. However, in alternative embodiments (not shown), tobacco product is understood to mean a product other than smoking product 1.

The smoking article 1 comprises a tobacco rod 2 and a tobacco product component 3.

The outer wrapper 4 surrounds the smoking article component 3 and the portion of the tobacco rod 2. The outer wrapper 4 includes rim paper 4 which attaches the tobacco rod 2 to the smoking article component 3. The tobacco rod 2 comprises a column of smoking material 5 surrounded by a rod wrap 6.

In the present embodiment, the tobacco product component 3 comprises a smoking product component 3 in the form of a smoking product filter 3. The smoking article component 3 comprises a filter material body 7 and a cavity 8. The body 7 comprises first and second filter material sections 9, 10. In the present embodiment, the first and second sections 9, 10 comprise first and second rods 9, 10 of filter material such as cellulose acetate. The first and second rods 9, 10 may be substantially cylindrical in shape, although it will be obvious to those skilled in the art that other shapes of the rod 9, 10 are also possible.

The first and second rods 9, 10 are spaced in the axial direction of the smoking article 1 so that the cavity 8 is located between the first and second rods 9, 10. The second rod 10 is located downstream of the tobacco rod 2. The first rod 9 is located below smoke flow from the second rod 10, on the other side of the cavity 8 relative to the second rod 10.

The cavity 8 has a length (indicated by the arrow ʼX' in Fig. 3) from 4 to 12 mm and preferably from 6 to 10 mm. However, in other embodiments, the implementation of the cavity 8 has a different length.

The cavity 8 of the smoking article component 3 contains additive capsules 11 and particles 12. In the present embodiment, the particles 12 are cellulose acetate (CA) particles 12. Thus, the gas passing through the body 7 passes through the cavity 8 and contacts the additive capsules 11. The additive capsules 11 are configured to selectively entrain the additive in the gas stream, as detailed below.

A sectional view of one of the additive capsules 11 is shown in FIG. 4. Each additive capsule 11 has an outer shell 13 and an inner content 14.

The shell 13 of each additive capsule 11 may be solid at room temperature. The shell 13 may contain, consist of, or essentially consist of alginate. However, it should be understood that in alternative embodiments, the implementation of the shell 13 may be formed from a different material. For example, shell 13 may alternatively contain, consist of, or essentially consist of gelatin, carrageenans, or pectins. The shell 13 may contain, consist of or essentially consist of one or more substances selected from alganate, gelatin, carrageenans or pectins.

The interior 14 of each additive capsule 11 contains, consists of, or essentially consists of an additive, such as a flavoring agent, designed to flavor the gas passing through the cavity 8 when the additive is in contact with the gas. However, it should be understood that in other embodiments, the additive may alternatively or additionally be another type of additive, such as a humectant. In the present embodiment, the inner content 14 is a liquid. However, in other embodiments (not shown), the interior 14 may include a solid, such as a powder.

The shell 13 of each of the additive capsules 11 may be impermeable or substantially impermeable to the additive from the inner contents 14. Therefore, the shell 13 initially prevents the additive from the inner contents 14 from leaking out of the additive capsule 11 and being trapped by the gas passing through the cavity 8. When the user it is necessary to entrain the additive with gas, for example, to flavor the gas, in embodiments where the additive is a flavor, the shells 13 of the additive capsules 11 are ruptured so that the additive can be entrained in the gas.

In some embodiments (not shown), the additive capsule 11 further comprises a carrier material. The carrier material may include, for example, gelatin.

The cellulose acetate particles 12 contain cellulose acetate which has been cured with a plasticizer such as triacetin. The plasticizer helps prevent the cellulose acetate particles 12 from breaking apart when the user applies force to the smoking article component 3 to break the additive capsules 11. In addition, the increased hardness of the additive capsules 11 due to the plasticizer contributes to the destruction of the additive capsules 11. It should be understood that cellulose acetate may alternatively or additionally be cured with another plasticizer such as diacetin, triethyl citrate or polyethylene glycol (PEG).

The cellulose acetate particles 12 may contain a plasticizer in the range of 15 to 40% by weight of the cellulose acetate particles 12, and preferably in the range of 20 to 35% by weight of the cellulose acetate particles 12. The cellulose acetate particles 12 may contain a plasticizer in an amount of at least 15% by weight of the cellulose acetate particles 12, and preferably at least 20% by weight of the cellulose acetate particles 12. The cellulose acetate particles 12 may contain a plasticizer in an amount of less than 40% by weight of the cellulose acetate particles 12, and preferably less than 35% by weight of the cellulose acetate particles 12.

In some embodiments, the cellulose acetate particles 12 may be made from a material with a Rockwell hardness of at least 25 HRC in accordance with ASTM D _{785 Procedure A.} Preferably, the particles 12 may be made from a material with a Rockwell hardness greater than 30, or greater than 40, or greater than 50, or greater than 60, or greater than 70, or greater than 80, or greater than 90, or greater than 100 Rockwell. It has been found that the high Rockwell hardness of the particles 12 prevents them from breaking when the user applies force to the smoking article component 3 to break the additive capsules 11, and also contributes to the destruction of the additive capsules 11.

In one embodiment, the particles have an average surface area of less than 50 m ² /g, and preferably less than 30, 20, 10, 5, or 3 m ² /g. The surface area can be measured according to standard ASTM D ₁₉₉₃ -18 (Standard Test Method for Precipitated Silica -Surface Area by Multipoint BET Nitrogen Adsorption, ASTM International, West Conshohocken, PA, 2018) (Standard test method for surface area of the precipitated silica by BET analysis of nitrogen uptake at several points). Particle density can refer to the density of the material of the particles, including the pores in the material, but excluding the voids between the particles (otherwise it would be "bulk density").

It has been found that the smaller the surface area of the particles, the stronger the particles are, which may be due to the fact that the particles are less porous. The higher particle strength promotes breakage of the additive capsules when an external force is applied to the wall of the tobacco product component. The higher particle strength also helps prevent the capsules from breaking during transit. In addition, it has been found that less surface area means that the particles take up less additive from the additive capsules when they burst, which means that more additive can be delivered to the user.

The particles contain a material with a particle density of at least 1 g/cm ³ , which makes it possible to make the particles stronger to ensure the breakage of the additive capsules during use and to prevent the breakage of the particles during transport. In some embodiments, the particles comprise a material with a particle density of at least 1.1 g/cm ³ or at least 1.2 g/cm ³ , whereby increasing the particle density increases the strength of the particles.

In one embodiment, the particles contain material with a particle density of less than 5 g/cm ³ , and preferably less than 2 g/cm ³ , or less than 1.5 g/cm ³ . The lower particle density results in a lighter weight of the smoking article component, which is therefore easier to transport.

In some embodiments, the particle density is 1 to 2 g/cm ³ , or 1.1 to 2 g/cm ³ , or 1.1 to 1.5 g/cm ³ .

In some embodiments, the particles are substantially cylindrical in shape. The particles can be obtained from the material made by extrusion of the rod and cut into individual essentially cylindrical particles.

In some embodiments, the particles have a drop hardness greater than 95%, and preferably greater than 96%, 97%, 98%, or 99%. In some embodiments, the impact hardness of the particles is greater than 99.5%, 99.6%, 99.7%, 99.8%, or 99.9%. Particle drop hardness can be measured using the hardness tests described in ASTM D ₃ 802-16 (Standard Test Method for Ball-Pan Hardness of Activated Carbon, ASTM International, West Conshohocken, PA, 2016) (Standard Method hardness testing of activated carbon by the falling head method). These tests are described for testing the hardness of activated carbon. However, this method is also suitable for measuring the hardness of other particulate materials. It has been found that increasing the drop hardness of the particles makes them stronger and therefore more effective at breaking additive capsules during use, and the particles are less likely to break during transport.

The cellulose acetate particles 12 may contain one or more surface formations designed to assist in breaking the additive capsules 11 when the user applies force to the smoking article component 3. For example, the surface formations may assist in cutting or piercing the shells 13 of the additive capsules 11 or crushing the additive capsules 11. In the present embodiment, each of the cellulose acetate particles 12 has one or more edges 15A and/or one or more corners 15B. Edges 15A and corners 15B may be formed, for example, by cutting or grinding portions of cellulose acetate to form cellulose acetate particles 12. Edges 15A and corners 15B facilitate cutting or tearing of the shell 13 of the additive capsules 11. Edges 15A may be corner edges. In an alternative embodiment (not shown), the cellulose acetate particles 12 do not have edges 15A and/or corners 15B and may be, for example, spherical. In the present embodiment, the cellulose acetate particles 12 include cellulose acetate flakes 12.

The smoking article component 3 allows the user to control the amount of additive that is added to the gas passing through the smoking article component 3. Initially, the shell 13 of each additive capsule 11 is intact and therefore the additive from the internal contents 14 is not introduced into the gas stream. When the user needs to add an additive, he applies an external force to the smoking article component 3 to break the shells 13 of the additive capsules 11 . In one example, the user securely holds the smoking article component 3 and rolls the smoking article component 3 between the fingers. This causes the cellulose acetate particles 12 to rupture the shells 13 of the additive capsules 11 so that the additive from the interior 14 is released through the shells 13 and into the gas stream. Preferably, the more the user rolls the smoking article component 3 between his fingers, the more additive capsules 11 are broken, and thus more additive is released into the gas stream. Therefore, the user can control the amount of additive that is added to the gas stream by controlling the time during which the component 3 of the smoking article is rolled between the fingers. Cellulose acetate is a readily available material that is already used in components made in the tobacco industry, for example as a filter material in cigarette filters. Thus, the abrasive material of the smoking article component 3 containing the cellulose acetate particles 12 simplifies the manufacture of the smoking article component 3.

In some embodiments, the cellulose acetate particles 12 may be made from a material with a melt viscosity in the range of 0.2 to 6 g/10 min in accordance with ASTM D ₁₂₃ 8. In some embodiments, the cellulose acetate particles 12 may be made from a material with a melt viscosity in the range of 0.25 to 5.5 g/10 min, or in the range of 0.5 to 4 g/10 min. In some embodiments, the melt viscosity is less than 5.5 g/10 min.

In one exemplary embodiment, the cellulose acetate particles 12 contain 28% triacetin and 72% cellulose acetate and the material has a melt viscosity of 414 mg/3 min (1.38 g/10 min). In another exemplary embodiment, the cellulose acetate particles 12 contain 25% triacetin and 75% cellulose acetate and the material has a melt viscosity of 266 mg/3 min (0.89 g/10 min).

The tip paper 4 contains one or more indicators 19 which provide a visual indication to the user indicating where an external force should be applied to the component 3 of the smoking article in order to release the additive. For example, the indicators 19 may indicate where to hold and roll the smoking article component 3 between your fingers in order to release the additive. The indicators 19 may, for example, be printed on the tip paper 4 or may have a label attached to the tip paper 4. The indicators 19 may be positioned above the cavity 8.

Component 3 of the smoking article additionally contains a ficell 16, which limits the cavity 8 and at least part of the first and/or second rods 9, 10. In the present embodiment, the ficell 16 covers the entire length of both the first and second rods 9, 10.

Part of the ficelle 16 and the rim paper 4 that covers the cavity 8 form the wall of the component 3 of the smoking article. The wall defines the cavity 8. The wall retains the additive capsules 11 and the cellulose acetate particles 12 within the cavity 8. The wall is deformable such that, in use, an external force is applied by the user to deform the wall radially inward to break the additive capsules 11. In the example shown above, the user grasps the wall and twists the smoking article component 3 between his fingers so that the cellulose acetate particles 12 break the shells 13 of the additive capsules 11 to release the additive. In embodiments where ficell 16 is absent, the wall may comprise tip paper 4. In embodiments where tip paper 4 is absent, the wall may comprise ficell 16. In some embodiments, the wall comprises an additional sheet of material (not shown) in addition to tip paper. paper 4 and/or ficells 16.

Fitella 16 contains a layer 17 of paper and an insulating layer 18. The insulating layer 18 is impermeable or substantially impermeable to the capsules 11 with the additive. Therefore, when the additive capsules 11 are broken so that the additive is entrained in the gas flow, the sealing layer 18 prevents the additive from seeping through the ficelle 16. This is advantageous because the smoking article 1 is usually held between the fingers in the area of the component 3 of the smoking article and thus the sealing layer 18 helps prevent the additive from coming into contact with the user's fingers.

In the present embodiment, the insulating layer 18 is provided as a cover 18 on the paper layer 17 . For example, coating 18 may contain ethylcellulose. In an alternative embodiment (not shown), the insulating layer 18 comprises a layer of material, such as a sheet of plastic or foil, which is bonded to the paper layer 17 with an adhesive. In some embodiments, sealing layer 18 is an oil repellant.

In one embodiment, an insulating layer 18 is provided on the inner surface of the paper layer 17 so that the paper layer 17 is located between the insulating layer 18 and the tipping paper 4. Alternatively, the insulating layer 18 can be located on the outer surface of the paper layer 17 so that the insulating layer 18 is between layer 17 of paper and rim paper 4.

In one embodiment, the insulating layer 18 is located on the entire inner and/or outer surface of the paper layer 17. However, in an alternative embodiment, the insulating layer 18 is provided only on a part of the inner and/or outer surface of the paper layer 17, for example, only on the portion of the paper layer 17 that defines the cavity 8.

As the smoking article component 3 is rolled between the user's fingers, the wall is deformed radially inward so that the additive capsules 11 and the cellulose acetate particles 12 are ground together. Fitella 16 is configured to provide structural support for the smoking article component 3 to help maintain the structural integrity of the smoking article component 3 while the smoking article component 3 is rotated to release the additive. In some embodiments, ficell 16 has a basis weight of at least 60 g/m ² , and preferably at least 80 g/m ² . This basis weight provides increased rigidity to the ficelle 16 to help maintain the structural integrity of the smoking article component 3 as the smoking article component 3 is rotated. In some embodiments, the basis weight of ficella 16 is in the range of 60 to 110 g/m ² , and preferably in the range of 80 to 110 g/m ² . The basis weight of the ficell 16 may be in the range of 60 to 100 g/m ² , or in the range of 80 to 100 g/m ² .

In one embodiment, the rigidity of ficell 16 is achieved by making paper layer 17 at least 35 micrometers thick, and preferably at least 50, 60, 70, 80, 90, or 100 micrometers thick. In some embodiments, the paper layer 17 has a thickness in the range of 35 to 137 micrometers. The stiffness of the ficell 16 helps the wall return to its original shape when the user stops rolling the component 3 of the smoking article to release the additive.

In some embodiments, the additive capsules 11 have a diameter of at least 0.6 mm. In some embodiments, the additive capsules 11 have a diameter of at least 0.8 mm, and preferably a diameter of about 1 mm.

In some embodiments, the additive capsules 11 are less than 1.4 mm in diameter. Preferably, the additive capsules 11 have a diameter of less than 1.2 mm, and preferably a diameter of about 1 mm.

It has been found that the smaller diameter of the additive capsules 11 results in less additive being introduced into the gas stream upon bursting of each additive capsule 11, thereby the user more precisely controls the amount of additive that is added to the gas stream by the duration of the smoking article component 3 being rolled between fingers.

In some embodiments, the additive capsules 11 have a diameter in the range of 0.6 to 1.4 mm, and preferably in the range of 0.8 to 1.2 mm.

In some embodiments, the additive capsules 11 have a particle size of at least 0.6 mm. The term "particle size" refers to the particle size measured by sieving through a sieve. Preferably, the additive capsules 11 have a particle size of at least 0.8 mm. In some embodiments, the supplement capsules have a particle size of less than 1.4 mm, and preferably a particle size of less than 1.2 mm. In one embodiment, the additive capsules 11 have a particle size in the range of 0.6 to 1.4 mm, and preferably in the range of 0.8 to 1.2 mm. Preferably, the additive capsules 11 have a particle size of about 1 mm.

In some embodiments, the cellulose acetate particles 12 have a size of at least 1 mm, and preferably at least 1.4 mm. The term "particle size" refers to the size measured when sieved through a sieve. Cellulose acetate particles 12 with a size of at least 1 mm, and preferably 1.4 mm, have been found to be particularly effective in rupturing additive capsules 11. In some embodiments, the cellulose acetate particles 12 are less than 2.4 mm in size, and preferably less than 2 mm. Cellulose acetate particles 12 with a size of less than 2.4 mm, and preferably less than 2 mm, have been found to be particularly effective in rupturing additive capsules 11.

In some embodiments, the cellulose acetate particles 12 have a size in the range of 1 to 2.4 mm, and preferably in the range of 1.4 to 2 mm. In one embodiment, the additive capsules 11 have a diameter/particle size in the range of 0.6 to 1.4 mm, and preferably in the range of 0.8 to 1.2 mm. This combination of the size of the additive capsules 11 and the size of the cellulose acetate particles 12 has been found to be advantageous for increasing the efficiency of the cellulose acetate particles 12 in bursting the additive capsules 11. In one embodiment, the component 3 of the smoking article contains from 20 to 100, and preferably from 40 to 80 particles 12 of cellulose acetate, or from 50 to 70 particles 12 of cellulose acetate.

The smoking article component 3 may include a blank space 20 at the mouth end of the smoking article component 3. In the embodiment of FIG. 1-6, the smoking article component 3 is a tubular filter 3, and at the mouth end of the smoking article component 3, an annular section 21 is provided so that the blank space 20 is located in the hollow center of the annular section 21. The annular section 21 may contain a filter material, for example, acetate cellulose.

The annular section 21 is located downstream of the first rod 9 and is attached to it with rim paper 4 and/or ficell 16. In another embodiment, the first rod 9 includes an annular section such that there is an unfilled space 20 in the first rod 9. In another embodiment, implementation (not shown), the component 3 of the smoking article is a filter 3 with a cavity. A tip paper 4, a ficell 16 or an additional wrap (not shown) may extend beyond the mouth end of the first filter material rod 9 to form a space in which there is an unfilled space 20, with no annular portion 21 present.

In one embodiment, each of the first and second rams 9, 10 contains a section of filter material, such as cellulose acetate or activated carbon, and each section is wrapped in its own ficelle (not shown). The first and second studs 9, 10 are then wrapped in a ficell 16 which also wraps the cavity 8. However, in alternative embodiments (not shown), separate ficells of the first and/or second studs 9, 10 are omitted. In some embodiments (not shown), the ficell 16 does not surround the first and/or second rods 9, 10 and optionally surrounds only the cavity 8.

In some alternative embodiments (not shown), the first and/or second rods 9, 10 are missing. For example, the second rod 10 may be omitted so that the cavity 8 is located between the first rod 9 and the tobacco rod 2.

In the embodiment described above, each supplement capsule 11 comprises an outer shell 13 and an inner contents 14. However, in alternative embodiments (not shown), outer shell 13 is omitted. In one embodiment (not shown), each additive capsule 11 comprises a body of a material that contains the additive, and there is no shell surrounding the body. In one embodiment (not shown), each additive capsule 11 contains a solid material that is ground, for example, to form a powder, when an external force is applied to the component 3 of the smoking article so that the additive can be entrained by the gas passing through the cavity 8. Cellulose acetate particles 12 help to break up the capsules 11 with additive to form a powder.
