Description

The present invention is a filter section for a smoking article that includes a cylindrical shape and extends from a distal end to a buccal end, thereby creating a flow path for at least one fluid; The filter section further includes a filter material and a cavity, the cavity being surrounded by the filter material.

Filter sections with cavities are known in the tobacco industry, especially when capsules for flavor enhancement are placed inside the cavity. These capsules often contain flavor compounds such as menthol, fruit flavors or other synthetic flavors. By fracturing the frangible outer shell of the capsules, they release the flavored contents, which results in additional flavor for the user.

Additionally, filter sections that include fluid-absorbing materials and thereby extract harmful components from vapor flowing through the filter section are also known in the tobacco industry. Absorbent materials typically contain hydrophilic properties and thereby absorb moisture containing harmful components from smoke.

Due to the fact that some users prefer the rich and natural flavor of tobacco while smoking, filters that emphasize the natural flavor of tobacco while smoking by including tobacco particles inside the filter are also used in the tobacco industry. It is publicly known. By contacting the smoke flowing through the filter section, such tobacco particles release additional tobacco flavor to the smoke. Thereby, a natural flavor enhancement of the smoke can be achieved.

To provide the consumer with a natural tobacco flavor and a smoking experience that minimizes harmful components, it is contemplated that tobacco particles may be mixed with hydrophilic materials. Due to the fact that the tobacco particles used inside smoking articles, particularly within the filter section, are usually not completely dry, they contain moisture. It is therefore disadvantageous to mix tobacco particles with hydrophilic materials inside the filter section outside the factory. Generally, it is advantageous to store tobacco particles and fluid-absorbing materials in a preserved state until shortly before consumption of the smoking article to avoid possible reactions with oxygen and moisture from the air.

It is therefore an object of the present invention to provide a filter section that prevents reaction with each other during storage and allows the components to be mixed immediately before use of the smoking article to provide natural flavor enhancement and absorption of harmful components. becomes possible. This object is achieved by the filter section of claim 1. Preferred embodiments of the invention are the subject of the dependent claims.

According to the invention, the internal cavity of the filter section includes at least two compartments in fluid communication with the filter section and blocked by a common frangible barrier, each of the compartments draining water from the fluid flow path. the first compartment comprises at least a first component, and the second compartment comprises at least a second component, the first component containing a dispersion a tobacco product, and the second component includes a fluid-absorbing material.

The common frangible barrier is preferably waterproof to prevent moisture exchange from the tobacco particles to the fluid-absorbing material. Preferably, the barrier also includes an edge and/or is connected to the filter material in such a way that no moisture exchange can occur around the frangible barrier.

It is conceivable that by simply arranging a common frangible barrier inside the filter material, no additional material is required for a capsule or similar compartment with a surrounding shell. This makes more space available for placement of components inside the filter section. In addition, manufacturing speed is increased compared to filters with capsules, since only a common frangible barrier needs to be placed inside the filter section and no additional capsules need to be manufactured.

The common frangible barrier is preferably made from a two-dimensional piece of material, while the capsule must be formed as a spherical three-dimensional body.

A common frangible barrier would include a membrane through which only air or gas can pass. Preferably, the membrane thereby filters harmful components and/or moisture from the air flowing therethrough.

In a preferred embodiment, the shell of the capsule and/or the common frangible barrier are made of a membrane capable of filtering harmful components from the smoke passing through the filter element. Preferably, these membranes are dialysis membranes that allow certain components to pass through while blocking other components. Semipermeable membranes specifically allow air to pass through, while other components are filtered out and therefore not inhaled by the consumer. Preferably, the membrane has a filter function.

Preferably, the frangible barrier is breakable by the consumer applying force to the area of the filter section in which the barrier is placed. The components inside the compartment preferably contact each other and preferably mix with each other upon breaking of the barrier. Preferably, the mixing efficiency of the components can also be improved by moving and/or vibrating the filter section after fracturing the frangible barrier.

A consumer can fracture the frangible barrier by applying force to the filter segments perpendicular to the longitudinal direction of the smoking article.

It is contemplated that the barrier will be dissolved by smoke passing by and/or through it, with dissolution preferably occurring when it is heated or when it comes into contact with moisture from smoke.

Preferably, the thickness of the frangible barrier comprises a maximum thickness in the longitudinal direction of the smoking article of 0.5 mm, more preferably 1 mm and most preferably 2 mm. The frangible barrier further comprises a minimum thickness in the longitudinal direction of 0.1 μm, preferably 10 μm and most preferably 0.1 mm.

Preferably, the frangible barrier comprises a two-dimensional shape of a plate having a circular, square and/or polygonal shape. Thereby, the barrier is preferably arranged inside the filter material, with its plane preferably perpendicular to the longitudinal direction of the filter section.

It is possible that by mixing the components they begin to react with each other. Furthermore, it is contemplated that at least one of the components includes additives that enhance the reaction between the components and/or with smoke.

It is contemplated that the frangible barrier will not rupture under force applied by the consumer and is preferably thermally decomposable, thereby at least partially dissolving itself upon heating. Preferably, the frangible barrier is heated from smoke flowing through the filter section and coming into contact with the barrier. Preferably, the dissolution of the barrier occurs completely automatically during smoking, so that the user does not have to manually fracture the barrier.

Preferably, the tobacco particles within the filter section include powder form. Preferably, the tobacco particles can also be mixed with additives to include the form of tobacco paste. It is believed that tobacco placed inside the filter section enriches the inhaled vapor with natural tobacco flavor, thereby particularly enhancing the consumer's smoking experience. The size of the tobacco particles is preferably greater than 10 μm.

It is envisaged that the tobacco within at least one of the compartments will be placed within the capsule, the tobacco preferably comprising powdered form. The capsules with the tobacco particles are also preferably made of membrane material, and the capsules are preferably flushed with smoke, thereby obtaining an enhanced tobacco flavor without the need to destroy the capsules. It is believed that the capsule releases only its flavor particles to the smoke passing through it, and that the solid particles remain within the capsule.

In another embodiment, the capsule includes SAP, and smoke passing through the capsule is cleaned and dried by moisture and/or harmful components that adhere to the SAP inside the capsule.

Also preferably, the tobacco particles are mixed with cellulose and/or different filter materials inside the compartment. It is contemplated that tobacco particles of various sizes may be arranged inside the filter section. Preferably, the tobacco particles include a powdered form, and the tobacco particles therefore include a larger surface so that they can react better and/or release their flavor.

In a preferred embodiment, the fluid-absorbing material within at least one of the compartments comprises at least one superabsorbent polymer (SAP). It is contemplated that the SAP material within one compartment may also be a mixture of different SAPs. It is contemplated that SAPs may include different shapes and/or properties. Preferably, at least two SAPs with different shapes and/or properties can be or are mixed together. This combines the favorable properties of different SAPs.

The SAP arrangement is useful for filtering harmful components from vapors inhaled by cigarette consumers. The SAP preferably absorbs moisture from within the vapor, thereby reducing the amount of harmful components in the vapor that are bound to the moisture and/or dissolved in the moist vapor.

The SAP is preferably a material that can absorb many times its own weight in liquid. Preferably, the SAP increases in volume upon absorbing liquid. Preferably, the SAP also changes its shape and/or properties when it absorbs water.

Preferably, at least one of the SAPs in the filter section comprises a powder shape and/or a three-dimensional shape, preferably a sphere, and/or a cube, and/or any other dimensioned shape.

SAP in powder form preferably becomes a hydrogel by absorbing fluid. The pre-shaped and/or solid body of SAP preferably maintains its shape by absorbing fluid, but increases in volume depending on the amount of fluid absorbed.

Preferably, SAPs suitable for use in the filter section are based on acrylic acid. Preferably, the SAP may be based on polyacrylamide. Mixtures of both are also conceivable in order to combine the favorable properties of the materials.

Preferably, other organic and/or inorganic SAP materials can also be used in the filter section. Preferably, a core crosslinker (CXL) is added to the polymer that makes it insoluble in water.

In preferred embodiments, the SAP within the filter material is environmentally friendly and/or non-toxic and/or includes biodegradable properties. Thereby, the SAP used may be a polysaccharide-based SAP. Preferably, the entire filter material is environmentally friendly and/or non-toxic and/or biodegradable, which reduces the problems associated with disposal of the filter sections.

In a preferred embodiment, SAP comprises starch aldehyde and citric acid. Preferably, starch aldehyde and citric acid are mixed in a ratio that results in SAP.

In a preferred embodiment, the SAP comprises a polysaccharide in which carboxymethyl cellulose is used as a component. Preferably, other cellulosic materials can also be used as components.

Preferably, the polysaccharide-based SAP comprises a maximum weight-related swelling ratio of 80 g/g to 100 g/g, preferably 84 g/g to 90 g/g, most preferably 87 g/g. Thereby, 1 g of SAP preferably absorbs and/or binds 87 g of fluid. It is contemplated that SAPs with different weight-related swelling ratios may be used in the filter section.

Preferably, the weight-related swelling ratio of the SAP is less than the theoretical maximum swelling ratio, which allows components with lower purity to be used, thereby lowering the cost of synthesizing the SAP.

Preferably, the amount of SAP inside the filter section is less than 10%, more preferably less than 7%, most preferably less than 5%. It is contemplated that the SAP inside the compartment of the filter section is mixed with cellulose fibers. Preferably, the SAP thereby comprises powder form. Preferably, the SAP includes different particle sizes and shapes. Preferably, SAP alone can also be placed inside the compartment without any further additives.

In a preferred embodiment, the compartments are separated by at least one frangible barrier, and the compartments and/or the frangible barrier are surrounded by a frangible sleeve. It is conceivable that the frangible sleeve is formed as a hollow cylinder, whereby the frangible barrier divides the hollow cylinder into at least two sections. Preferably, this reduces reactions and/or moisture exchange between components within the individual compartments. Preferably, only one compartment is surrounded by a frangible sleeve. In particular, it is conceivable that the compartment with highly reactive components is surrounded by a frangible sleeve.

Preferably, the frangible sleeve is rupturable when the consumer applies force to rupture the frangible barrier. Preferably, the frangible sleeve is also thermally decomposable, thereby at least partially melting itself upon heating. Preferably, the frangible sleeve is in fluid communication with the smoke inside the filter so that it is heated by the smoke during the smoking process.

It is contemplated that the frangible sleeve is arranged inside the internal compartment of the filter section. Preferably, the sleeve thereby seals the compartment from the filter material surrounding the compartment. Preferably, the sleeve is arranged by coating the inner wall of the filter material facing the compartment. Preferably, the coating is applied by spray painting. The sleeve is preferably made from organic material, most preferably from starch.

The sleeve preferably includes the shape of the compartment so as to preferably surround the interior volume of the compartment. It is contemplated that the sleeve includes a longitudinal shape, the longitudinal axis of which is preferably arranged parallel to the longitudinal axis of the filter material. Preferably, the sleeve comprises a cylinder, square tube or other polygonal shape in its cross-sectional view.

It is contemplated that the sleeve comprises a minimum cross-sectional diameter of 1 mm, more preferably 3 mm and most preferably 5 mm. The sleeve preferably comprises a maximum cross-sectional diameter of 6mm, more preferably 8mm and most preferably 10mm.

In a preferred embodiment, at least one component in one of the compartments comprises pasty and/or fluid properties, and mixing of the components in the compartment by breaking the frangible barrier results in a fluid and/or pasty property. This produces a mixture with a consistency of .

In a preferred embodiment, at least one of the compartments contains at least one capsule, the capsule containing a further component of the mixture. Preferably, the capsule contains a fluid component that would react with other components and/or filter materials if not stored within the capsule. The SAP is also preferably placed within the capsule to prevent the SAP from reacting with moisture prior to use of the filter section and/or smoking article. Preferably, the capsule contains a fluid that wets the components within the compartment. Preferably, the capsule is placed within a compartment with tobacco particles to wet the tobacco article and produce a tobacco paste. Preferably, such fluids are aerosol formers and/or flavor enhancing ingredients.

It is conceivable that the capsule material also includes membrane material. Preferably, the membrane keeps the internal pressure of the capsule low to allow fluid and preferably air to pass through it. It is envisaged that the membrane acts as a filter to filter moisture and/or harmful components from smoke and/or gases passing through it. In a preferred embodiment, the capsule includes at least one frangible barrier, whereby the capsule is divided into at least two compartments. Preferably, each compartment within the capsule contains a different component. Also preferably, the components inside the capsule are mixed upon destruction of the common frangible barrier. It is conceivable that the shell of the capsule also ruptures upon rupture of the frangible barrier, thereby releasing the mixture into the filter material of the filter section.

It is contemplated that the capsules placed in the compartments of the filter section are breakable by the consumer applying force to the filter section. Preferably, the capsule is placed inside the filter section so that it is fractured at the same time as the frangible barrier is placed. Preferably, the capsule is also arranged so that the consumer can separately destroy the barrier and capsule.

Preferably, the capsule is also thermally decomposable, thereby at least partially dissolving itself upon heating. Preferably, the capsule is in fluid communication with the smoke inside the filter so that it is heated by the smoke during the smoking process.

In a preferred embodiment, the compartments are arranged such that they are surrounded by smoke and/or vapor flowing through the filter section along the flow path. Preferably, smoke flows through the compartment even when the frangible barrier is breached. Preferably, the smoke thereby reacts with at least one component inside the compartment.

In a preferred embodiment, the mixture is a gel. It is believed that by combining at least two components, they will react with each other to form a gel. Preferably, the mixture of ingredients becomes a gel by reacting with smoke during the smoking process. It is also conceivable that the mixture breaks up a capsule with a fluid component, which becomes a gel when mixed with the mixture.

In a preferred embodiment, the filter material includes a porous structure that allows the mixture to be distributed inside the filter section. Preferably the filter wicks the mixture. It is believed that by applying force to the filter portion and thereby deforming it, the mixture can be dispersed within the filter material. Dispersion of the mixture during shaking and/or movement of the filter section is also possible.

placing one component within one compartment;
placing different components within the other compartment;
It is also accomplished by a method that includes forming a filter section.

Preferably, the filter section is formed first and then the cavity is formed. Preferably, the first component is then placed inside the cavity, then the frangible barrier is placed, and finally the second component is placed inside the cavity.

In a preferred method, further frangible barriers are arranged to achieve further compartmentation. In this embodiment, two frangible barriers preferably separate three compartments with three different components.

It is contemplated that more frangible barriers may be placed inside the filter section, thereby creating additional compartments. Preferably, at least one compartment contains a capsule, and preferably the capsule is also thermally dissolvable. It is conceivable that the capsule is arranged in at least two compartments. These two capsules preferably contain different wall thicknesses and therefore release their contents with a time delay when exposed to heat.

In a preferred embodiment, the compartment is placed within a cavity within the filter material. Preferably, the frangible barrier constitutes a partition between the compartments.

In a preferred embodiment, the frangible sleeve is created by coating the surface of the cavity with a sealing material. Preferably, the frangible sleeve includes a thinner wall thickness, allowing storage of a larger amount of ingredient compared to what fits inside the capsule. Preferably, the frangible sleeve is liquid tight and preferably also functions as a capsule. The frangible sleeve may be applied by assembling the filter section with the cavity and then spraying it with a suitable sealing material.

In a preferred embodiment, a filter section can be used with a smoking article, wherein the internal cavity of the filter section includes at least two compartments in fluid communication with the filter section and separated by a common frangible barrier; Each of the compartments contains a component for a mixture having hydrophilic properties that absorbs water from the fluid flow path, the first compartment containing at least a first component, and the second compartment containing at least a second component. The first component includes a dispersed tobacco product and the second component includes a fluid-absorbing material.

In a preferred embodiment, the fluid-absorbing material within at least one of the compartments comprises at least one superabsorbent polymer (SAP). Preferably, the fluid-absorbing material includes at least one SAP.

Preferably, the smoking article includes at least one tobacco section that produces smoke and/or vapor when heated. This smoke therefore preferably flows through the filter section and comes into contact with the components inside the filter section. Thereby, the components are likely to react with smoke and/or vapor for the intended purpose.

Further advantages and embodiments according to the invention are illustrated in the accompanying drawings.

1 is a smoking article having a filter section according to the invention. 1 is a filter section according to the invention. 2 is a filter section with a capsule. A filter section with a mixture.

Figure 1 shows a filter section 1 according to the invention attached to a tobacco section 14 of a smoking article 2, the tobacco section 14 being attached to the distal end 3 of the filter section. The filter material 5 within the filter section 1 is thereby in fluid communication with the tobacco section 14. The filter section 1 itself includes a cavity 6, which is divided by a frangible barrier 12 into a first compartment 7a and a second compartment 7b. The first compartment 7a is arranged on the side of the frangible barrier 12 facing the distal end 3 of the filter section. The second compartment 7b is arranged on the side of the frangible barrier 12 facing the mouth end 4 of the filter section.

Preferably, the first component 8a inside the first compartment 7a is a dispersed tobacco product 10 and the second component 8b inside the second compartment 7b is a fluid-absorbing material 11. It is contemplated that the ingredients within the compartments may be varied, the first compartment 7a thus comprising the fluid-absorbing material 11 and the second compartment 7b comprising the dispersed tobacco product 10.

In FIG. 1, fluid flow path f indicates the direction that smoke and/or vapor generated within tobacco section 14 of smoking article 2 takes when smoking article 2 is used by a consumer. Smoke and/or vapor exits the tobacco section 14 along fluid flow path f and enters the distal end 3 of the filter section. This brings the smoke and/or vapor into contact with the filter material 5.

The filter material 5 includes a cavity 6 in which a compartment 7 is placed. The smoke and/or vapor flowing through the filter material 5 thereby also comes into contact with the cavity 6 and thus also with the component 8 arranged inside the compartment 7 inside the cavity 6 . Upon contact with the components 8, smoke and/or vapors react with them and finally exit the smoking article 2 through the mouth end 4 of the filter section.

FIG. 2 shows the same filter section as shown in FIG. 1, this filter section 1 not being attached to the tobacco section 14 to form a smoking article according to FIG. The filter section 1 of FIG. 2 can thereby be used for other products such as self-rolling cigarettes, cigarettes for heating non-combustion devices or other products where it is beneficial to filter smoke and/or add additional flavors. can be attached to a variety of smoking articles.

The filter section 1 of FIG. 2 includes a cavity 6 , a compartment 7 , a component 8 and a frangible barrier 12 . Preferably, the cavity 6 is arranged centrally in the filter section 1 with respect to the distal end 3 and the oral end 4. The frangible barrier 12 is also preferably arranged centrally in the filter section 1 with respect to the distal end 3 and the oral end 4. Thereby, the frangible barrier 12 preferably divides the cavity 6 equally into two compartments 7, the first compartment 7a containing the same volume as the second compartment 7b.

Flow path f in FIG. 2 indicates the direction of flow of steam and/or smoke flowing through the filter section 1. Preferably, the smoke and/or vapor is evenly distributed inside the filter section 1 to better react with the components 8 inside the filter section.

FIG. 3 shows a filter section 1 with a cavity 6 inside the filter material 5, inside of which a capsule 13 is arranged. Thereby, the component 8 is not placed directly inside the cavity 6, but is placed in the capsule 13 before being placed inside the filter section 1. The capsule 13 therefore preferably comprises at least one frangible barrier 12 inside the capsule 13, which frangible barrier thereby separates the components 8 inside the capsule 13.

Preferably, the interior space of the capsule 13 is divided into a first compartment 7a and a second compartment 7b, the first compartment 7a containing the first component 8a and the second compartment 7b containing the second component 8a. Contains component 8b. It is envisaged that the capsule 13 comprises a further frangible barrier 12 and thereby also comprises more compartments 7 and more preferably also more components 8.

It is envisaged that at least two capsules 13 are present inside the filter section 1 , each of the capsules 13 thereby preferably containing a different component 8 .

Preferably, two capsules 13 are arranged inside the filter section 1, the first capsule 13 containing the tobacco product 10 and the second capsule 13 containing the fluid-absorbing material 11.

Preferably, a plurality of capsules 13 can also be arranged within the filter section 1. Preferably, all capsules 13 contain different components 8 that react with each other when the capsules are crushed.

Placing at least one capsule 13 inside the filter section preferably makes the assembly process easier and/or faster. This is believed to result because the filter material 5 can be placed first and then the pre-assembled capsule 13 can be placed inside the filter material 5. This eliminates the need for stepwise filling and/or assembly of the cavity 6 with the component 8 and the frangible barrier 13.

Figure 3 further shows a flow path f for steam and/or smoke. Cavity 5 is placed in the same location as in FIGS. 1 and 2, the only difference from the previous figures being that cavity 6 is not filled directly with component 8, but with capsule 13.

FIG. 4 again shows the filter section 1 with the filter material 5, the fluid flow path f, the cavity 6 and the frangible barrier 12, the frangible barrier of FIG. 4 being fractured, thereby separating the compartments 7 from each other. I won't let you. Thereby, compartment 7a and compartment 7b are in fluid communication with each other, which means that components 8 can mix with each other.

In the embodiment of FIG. 4, the first compartment 7a with the first component 8a and the second compartment 7b with the second component 8b are in fluid communication with each other and the first component 8a and the second component 8b are in fluid communication with each other. are mixed with each other to form mixture 9.

Preferably, the mixture 9 includes a tobacco product 10 and a fluid absorbent material 11. When smoke and/or vapors flow through the filter 1, in particular the filter material 5 having components 8 therein, the smoke and/or vapors come into contact with the mixture 9 and thereby react with it. Thus, the tobacco product 10 enhances the flavor of the smoke and/or vapor, and the fluid absorbent material 11 absorbs moisture and thereby absorbs harmful components from the smoke and/or vapor.

Preferably, the mixture 9 comprises a powdered form, which provides a higher possible absorption rate of the fluid-absorbing material 11 and also provides a greater flavor emphasis from the tobacco product 10 within the mixture 9. Preferably, the mixture 9 can thereby be distributed inside the filter material 5 by vibrating and/or moving the filter section 1.

Preferably, the mixture 9 may comprise a fluid or semi-fluid consistency, the fluid consistency preferably causing the filter material 5 to absorb the mixture 9 and disperse it within the filter section 1.

Preferably, the mixture 9 also has a pasty consistency, and the dispersion of the mixture 9 having a pasty consistency is preferably carried out by the consumer applying force to the filter section 1.

Preferably, the mixture 9 in fluid form is at least partially absorbed by the filter material 5. If the mixture comprises powder form, it is contemplated that the individual particle size is preferably small enough to dissipate into the filter material 5. Preferably, the mixture 9 is uniformly distributed inside the filter material 5 so as to include a larger reactive surface for reacting with smoke and/or vapor.
