DETAILED DESCRIPTION OF THE INVENTION The porous mass described below can be used with a smoking device, for example a tobacco smoking device. The porous mass includes active particles and non-fibrous binding particles and can form a part of a filter section of a smoking device. The term "porous mass", as used herein, refers to a mass comprising active particles and non-fibrous binder particles which form a structure bonded by the binding particles and which includes hollow spaces therein, by which the smoke can be transport through the porous mass and interact with the active particles. In some embodiments, the structure can be formed through the application of heat so that the binding particles soften to join the active particles at various points of contact. Although reference is made here to "tobacco", it will be understood that the porous mass described herein is also suitable for use with other substances that produce smoke when burned or heated (ie, substances that can be smoked).

It should be noted that when "approximately" is given below with reference to a number, the term "approximately" modifies each number in the numerical list. It should be noted that in some numerical lists of intervals, some lower limits listed may be greater than some upper limits listed. Those skilled in the art will recognize that the selected subset will require the selection of an upper limit greater than the selected lower limit.

With reference to figures 1-4, various embodiments of a smoking device (these are representative, but not limitative, of the smoking devices contemplated below). The term "smoking device", as used herein, usually refers to a cigarette, but is not so limited and could be used with other smoking devices, eg nozzles, cigars, cigar holders, pipes, pipes of water, hookahs, electronic smoking devices, cigarettes or rolling cigarettes, etc. Hereinafter, a cigarette is referred to as a generic term covering all these smoking devices (unless otherwise specified).

In some embodiments, a smoking device may comprise a housing that can hold a substance that can be smoked in fluid contact with the filter. Suitable accommodations may include, among others, a cigarette, a mouthpiece, a cigarette, a cigar holder, a pipe, a water pipe, a narghile, an electronic smoking device, a rolling cigarette, a rolling cigarette and a paper.

In Figure 1, the cigarette 10 includes a tobacco column 12 and a filter 14. The filter 14 can comprise at least dps sections, a first section 16 and a second section 18. For example, the first section 16 can comprise conventional filter (discussed in more detail below) and second section 18 comprises a porous mass (discussed in more detail below).

As used herein, the term "tobacco column" refers to the mixture of tobacco and, optionally, other ingredients and flavorings that they can be combined to produce a smoking article based on tobacco, for example a cigarette or cigar. In some embodiments, the tobacco column may comprise ingredients selected from the group consisting of: tobacco, sugar (for example sucrose, brown sugar, invert sugar or high fructose corn syrup), propylene glycol, glycerol, cocoa, cocoa products, cocoa, a locust bean gum, carob extracts and any combination of these. In other embodiments, the tobacco column may further comprise flavorings, menthol, licorice extract, diammonium phosphate, ammonium hydroxide and any combination thereof. Examples of suitable types of tobacco that can be used in tobacco columns may include, among others, bright leaf tobacco, Burley tobacco, oriental tobacco (also known as Turkish tobacco), Cavendish tobacco, Corojo tobacco, Creole tobacco, Periquot tobacco, , shade tobacco, white Burley tobacco and any combination of these. Tobacco can be grown in the United States or cultivated in a jurisdiction outside the United States.

In Figure 2, the cigarette 20 has a tobacco column 12 and a filter 22. The filter 22 is multi-segmented with three sections. In this embodiment, conventional filter materials 24 (or other alternative filter sections) may flank porous mass 26.

In Figure 3, the cigarette 30 has a tobacco column 12 and a filter 32. The filter 32 is multi-segmented with four sections. In this embodiment, the final section 34 is a conventional material, but the sections 36, 37 and 38 can be any combination of the other filter materials and the porous mass (as long as at least one of those sections is a porous mass of the present invention).

The above embodiments are representative and not limiting. The novel filters can have any number of sections, for example, 2, 3, 4, 5, 6 or more sections and the sections can be placed in any suitable configuration. It is preferred that at least one of the filter sections comprise a porous mass of the present invention. In addition, the sections may be the same or different from each other.

Examples of sections that may be incorporated with the porous masses of the present invention to form filters may include, but are not limited to, sections comprising at least one element selected from the following: cellulose acetate, polypropylene, polyethylene, polyolefin trailer, polypropylene trailer , polyethylene terephthalate, polybutylene terephthalate, randomly oriented acetate, papers, corrugated papers, concentric filters (eg, a peripheral fibrous tow filter and a core of a sheet material), carbon trailer (sometimes nominated) Dalmatian filter "), silica, magnesium silicate, zeolites, molecular sieves, metallocenes, salts, catalysts, sodium chloride, nylon, flavorings, tobacco, capsules, cellulose, cellulose derivatives, catalytic converters, iodine pentoxide, coarse powders, particles carbon, carbon fibers, fibers, glass beads, nanoparticles, vacuum chambers (eg, formed by eleme rigid objects, for example paper or plastic), inclined vacuum chambers and any combination of these. If a zeolite is used, examples of suitable zeolites include, among others, BETA, SBA-15, MCM-41, MCM-48 modified by 3-aminopropylsilyl groups and any combination thereof. In some embodiments, the filter may be substantially degradable over time (eg, for about 2 to about 5 years), either naturally or in the presence of a catalyst, which in some embodiments, may be present in a section of filter itself. Also included are fibrous trailers and papers with active materials (bonded, impregnated or otherwise incorporated). Such active materials include activated carbon (or carbon), ion exchange resins, zeolites, desiccants, catalysts or other materials adapted to affect tobacco smoke. If used, the vacuum chambers can be filled (or partially filled) with ingredients or active materials that incorporate the active ingredients. Said active ingredients include activated carbon (or carbon), ion exchange resins, desiccants or other materials adapted to affect tobacco smoke. In addition, the section can be a porous mass of binding particles (ie, binding particles alone without any active particles). For example, this porous mass without active particles can be made with thermoplastic particles (for example polyolefin powders, even the binder particles set out below) which are bonded or molded together in a porous cylindrical shape.

In another embodiment, a section may comprise a space defining a cavity between two filter sections (a section including a porous mass of the present invention). The cavity can be filled with granulated carbon, for example, or a flavoring, as another example. The cavity may contain a capsule, e.g. eg, a polymeric capsule, which contains a flavor or catalyst. The cavity, in some embodiments, may also contain a molecular sieve that reacts with selected components in the smoke to eliminate or reduce the concentration of the components without adversely affecting the desirable flavor components of the smoke. In one embodiment, the cavity may include tobacco as an additional flavoring. It should be noted that if the cavity is not sufficiently filled with a chosen substance, in some embodiments, this may result in a lack of interaction between the components of the mainstream smoke and the substance in the cavity and in the other filter sections.

Flavors that may be suitable for use in the present invention include any flavor suitable for use in smoking devices that include those that give a taste or flavor to the smoke stream. Flavors may include, among others, organic material (or particles with natural flavors), carriers of natural flavors, carriers of artificial flavors and any combination thereof. Organic materials (or particles with natural flavors) include, among others, tobacco, cloves (e.g., ground cloves and clove flowers), cocoa and the like. The natural and artificial flavors may include, among others, menthol, cloves, cherry, chocolate, orange, mint, mango, vanilla, cinnamon, tobacco and the like. Said flavors can be provided by menthol, anethole (licorice), limonene (citrus), eugenol (clove) and the like. In some embodiments, more than one flavor can be used, including any combination of the flavors provided herein. These flavors can be placed in the tobacco column or in a section of a filter. In addition, in some embodiments, the porous masses of the present invention may comprise a flavor. The amount to be included will depend on the desired level of taste in the smoke taking into account all the filter sections, the length of the smoking device, the type of smoking device, the diameter of the smoking device, as well as other known factors for smoking. understood in the art.

The sections comprising a filter can be wrapped with paper to form filter rods. The term "paper", as used herein, refers collectively to any wrapping paper that is used in the production of smoking devices, including nozzle paper, wrapping paper, base paper and the like. Suitable papers for use in conjunction with the present invention include wood papers, pads containing flax, flax papers, functionalized papers (eg, those that are functionalized to reduce tar or carbon monoxide), special papers of marking, colored papers and any combination of these. In some embodiments, the papers may be of high porosity, corrugated or have high surface resistance. In some embodiments, the papers may comprise additives, sizing or printing agents. In In some embodiments, filter bars comprising a porous mass of the present invention can have lengths ranging from about 80 mm to about 150 mm. During processing, the filter rods can subsequently be divided into about 4 or about 6 individual segments of between about 5 and about 35 mm in length during a grinding operation of a smoking device. For double or triple filters, filters can first be cut into segments and combined with paper or carbon segments before grouting. The filter rods can be attached to the tobacco column with paper or other smoking apparatus to produce a finished smoking device. As an example, in the traditional manufacture of cigarettes, at least three papers are used: of wrapping, cigarette paper and nozzle paper. Wrapping refers to the paper that is used to cover the filter section of the cigarette while that filter is being produced and before it is attached to a column of tobacco. Cigarette paper refers to the paper that is used to cover the section of the tobacco column of the cigarette while that column of tobacco is produced and before it is attached to a filter section. Finally, nozzle paper refers to the paper used to cover the filter section and a part of the tobacco column while the two sections are joined to form a cigarette. The bonds of the various papers used to form a cigarette are joined using at least one adhesive and more than one type of adhesive can be used in the formation of the cigarette. As an example, while forming A traditional cellulose acetate filter section, you can use a polyvinyl alcohol adhesive to secure the filter to the paper and you can use a hot melt glue on the edge of the paper to keep the filter wrapped. Also, the cigarette paper can use a starch adhesive to join the edges of the paper. Finally, the nozzle paper can be more completely coated, it is coated on most of the surface instead of just in the sewing area, with a hot melt adhesive to ensure that the filter section and the tobacco section remain properly united. In some cigarette products, ventilation holes are made through the nozzle paper, or through the nozzle and wrapping paper to allow air to be drawn into the smoke stream.

In some embodiments, the filters may have a diameter in the range of between about 5 mm and about 10 mm and a length between about 5 mm and about 35 mm. In some embodiments, for example for ultra-thin or super-thin, the filters may have a diameter in the range of less than 5mm, for example, 3mm or less, including, but not limited to, a diameter limit of less than 0.5mm. For cigarette embodiments, the filters may have a diameter greater than 20 mm, for example about 30 mm, as desired. Similarly, the filter size for other smoking devices may vary based on the intended use and consumer demand (eg, in a pipe).

In Figure 4, a pipe 40 has a lit container 42, a nozzle 44 and a channel 46 which interconnects with the lit container 42 and the nozzle 44. The channel 46 includes a cavity 47. The cavity 47 is adapted for reception of a filter 48. The filter 48 can be a multi-segmented filter as presented above or it can consist solely of the porous mass. The size of the filter may vary based on the dimensions of the cavity 47. In some embodiments, the filter 48 may be removable, replaceable, disposable, recyclable or degradable.

In the above embodiments, the conventional materials and the porous mass are "bonded". The term "attached", as used herein, means that the porous mass is neighboring in line (or in series) of a tobacco column or other filter section, so that when the cigarette is smoked, the smoke of the column of tobacco must pass through (eg, in series) the porous mass to reach its intended recipient (eg, a smoker). As indicated above, the porous mass can be attached to the tobacco column through paper wrapping techniques, e.g. eg, using paper or an adhesive. Furthermore, in some embodiments, the porous mass can be attached to the tobacco column using an adhesive, which is preferably free of components which, upon ignition, could interfere with the purposes of the invention.

As shown in Figures 1-3, in some embodiments, a filter section comprising a porous mass and at least one other distinct filter section may be coaxial, juxtaposed, contiguous, and have equivalent transverse areas (or substantially equivalent transverse areas) . However, it is understood that the porous mass and conventional materials do not need to be bonded in such a manner and that other possible configurations may exist. In addition, while, it is anticipated that the porous mass, more often, will be used in a combined or multi-segmented cigarette filter configuration, as shown in Figures 1-3; the invention is not so limited and a smoking device may comprise only a porous mass of the present invention, as presented above with respect to figure 4. Further, although in some embodiments, the porous mass will be juxtaposed to the tobacco column , as shown in figure 1, the present disclosure is not so limited. For example, a porous mass of the present invention can be separated from the tobacco by a hollow cavity (eg, a tube or channel, for example in a pipe or hookah or cigarette holder or cigar holder), for example, see Figure 4. In other embodiments, a porous mass of the present invention can be separated from a tobacco column by a folding element, which allows a consumer to shape the smoking device.

In some embodiments, the porous masses of the present invention comprise active particles that bind at least partially with the binding particles. For example, see FIG. 5, a photomicrograph of an embodiment of the porous mass wherein there are active particles (eg, activated carbon particles) 50 and binding particles 52.

In 54 an example of a point of contact is shown. Note: in this embodiment (Figure 5), the binding particles and the active particles are joined at contact points, which points of contact are randomly distributed through the porous mass and the binding particles have retained their original physical form (or substantially retained its original form, eg, no more than 10% variation (eg, reduction) in the form of the original). (The active particles and the binder particles as discussed in more detail below). Without intending to be limited to any theory, it is believed that the contact points are formed when the binding particles are heated to their softening temperature, but not hot enough to reach a true melting. In some embodiments, it is believed that the porous masses of the present invention are constructed so that they exhibit a minimum encapsulated pressure drop (defined below) while maximizing the surface area of the active particles.

There may be any weight ratio of active particles to the binding particles in the porous mass. In some embodiments, the ratio can be between about 1 and about 99% by weight of active particles and between about 99 and about 1% by weight of binder particles. In some embodiments, the ratio can be between about 25 and about 99% by weight of active particles and between about 1 and about 75% by weight of particles binders In some embodiments, the ratio can be between about 40 and about 99% by weight of active particles and between about 1 and about 60% by weight of binder particles. In one embodiment of the porous mass, the active particles comprise between about 50 and about 99% by weight of the mass while the binding particles comprise between about 1 and about 50% by weight of the mass. In another embodiment, the active particles comprise between about 60 and about 95% by weight of the mass; while the binder particles comprise between about 5 and about 40% by weight of the dough. In addition, in another embodiment, the active particles comprise between about 75 and about 90% by weight of the dough while the binder particles comprise between about 10 and about 25% by weight of the dough.

In one embodiment of the porous mass, the porous mass has an empty volume in the range of between about 40% and about 90%. In another embodiment, it has an empty volume of between about 60% and about 90%. In another embodiment, it has an empty volume of between about 60% and about 85%. The empty volume is the remaining free space after counting the space occupied by the active particles.

To determine the empty volume, although you do not want to be limited to no particular theory, it is believed that the evidence indicates that the final density of the mixture was driven almost completely by the particle active; therefore, the space occupied by the binding particles is not considered for this calculation. Therefore, the empty volume, in this context, is calculated based on the remaining space after counting the particles active In order to determine the empty volume, we first averaged the upper and lower diameters based on the mesh size of the active particles and then the volume was calculated (assuming a spherical based on that averaged diameter) and using the density of the active material Then, the percentage of empty volume of the following is calculated mode: [(volume of the porous mass, cm3) - (weight of the Volume active particles, gm) / (density of the particles empty (%) = "active, gm / cm3)] * 100 Volume of the porous mass, cm3 In one embodiment, the porous mass has a pressure drop encapsulated (EPD) in the range of between about 0.10 and approximately 25 mm of water per mm of porous mass length.

As used herein, the term "encapsulated pressure drop" refers to the difference in static pressure between the two ends of a sample when it is traversed by an air flow in stable conditions when the Volume flow is 17.5 ml / sec at the exit end when the sample is completely encapsulated in a measuring device so that air can pass through the envelope. EPD has been measured in the present with the method recommended by CORESTA ("Cooperation Center for Tobacco-Related Scientific Research") No. 41, dated June 2007. In another embodiment, a porous mass of the present invention may have an EPD in the range of between about 0.10 and about 10 mm of water per mm of porous mass length. In other embodiments, a porous mass of the present invention may have an EPD of between about 2 and about 7 mm water per mm porous mass length (or not greater than 7 mm water per mm porous mass length). To obtain the desired EPD, the active particles must have a particle size greater than that of the binder particles. In one embodiment, the ratio of the size of the binder particles to achieve the particle size is in the range of between about 1: 1.5 and about 1: 4.

In some embodiments, the porous mass of the present invention may have an active particle charge of at least about 1 mg / mm, 2 mg / mm, 3 mg / mm, 4 mg / mm, 5 mg / mm, 6 mg / mm, 7 mg / mm, 8 mg / mm, 9 mg / mm, 10 mg / mm, 11 mg / mm, 12 mg / mm, 13 mg / mm, 14 mg / mm, 15 mg / mm, 16 mg / mm, 17 mg / mm, 18 mg / mm, 19 mg / mm, 20 mg / mm, 21 mg / mm, 22 mg / mm, 23 mg / mm, 24 mg / mm or 25 mg / mm in combination with an EPD of less than about 20 mm of water or less per mm of porous mass, 19 mm of water or less per mm of porous mass, 18 mm of water or less per mm of porous mass, 17 mm of water or less per mm of porous mass, 16 mm of water or less per mm of porous mass, 15 mm of water or less per mm of porous mass, 14 mm of water or less per mm of porous mass, 13 mm of water or less per mm of porous mass, 12 mm of water or less per mm of porous mass, 11 mm of water or less per mm of porous mass, 10 mm of water or less per mm of porous mass, 9 mm of water or less per mm of porous mass, 8 mm of water or less per mm of porous mass, 7 mm of water or less per mm of porous mass, 6 mm of water or less per mm of porous mass, 5 mm of water or less per mm of porous mass, 4 mm of water or less per mm of porous mass, 3 mm of water or less per mm of porous mass, 2 mm of water or less per mm of porous mass or 1 mm of water or less per mm of porous mass. By way of example, in some embodiments, the porous mass can have an active particle charge of at least about 1 mg / mm and an EPD of about 20 mm of water or less per mm of porous mass. In other embodiments, the porous mass may have an active particle charge of at least about 1 mg / mm and an EPD of about 20 mm of water or less per mm of porous mass, wherein the active particle is not carbon. In other embodiments, the porous mass may have an active particle comprising carbon with a charge of at least 6 mg / mm in combination with an EPD of 10 mm of water or less per mm of porous mass.

Depending on how the porous mass is made, the porous mass can have any desired length. In a batch molding process, for example, it is likely that the length coincides with the size of the molds used. In addition, it is a continuous production process, the porous mass can be a continuous long cylinder of any desired length. In both cases, the porous mass could subsequently be cut into smaller sections or desired lengths. The desired length may depend on the particular application in which the porous mass can be used. In one embodiment, the porous mass may have a length of between about 1 mm and about 35 mm. In another embodiment, the porous mass can have a length of between about 2 mm and about 30 mm. In another, the porous mass can have a length between about 7 mm and about 20 mm.

The porous mass can have any physical form. The porous mass may have a helical shape, a triangular shape, a disk shape or a square shape, in some embodiments. In one embodiment, it is in the form of a cylinder. A hybrid form of these forms may also be adequate. In some embodiments, the porous mass can be machined to be lighter in weight, if desired, for example, by piercing a portion of the porous mass. In one embodiment, the porous mass may have a specific shape for a nozzle or pipe that is adapted to enter the nozzle or pipe to allow passage of smoke through the filter to the consumer. When speaking of the shape of a porous mass in the present, with respect to the filter for a traditional smoking device, the shape can be termed in terms of diameter or circumference (where the circumference is the perimeter of a circle) of the cross section of the cylinder. But in embodiments where a porous mass of the present invention is in another form than a true cylinder, it will be understood that the term "perimeter" is used to refer to the perimeter of any shaped cross section, including a circular cross section.

The active particles can be any material adapted to improve the smoke that flows through it. Adapted to improve the smoke that flows through it refers to any material that can remove, reduce or add components to the smoke stream. The elimination or reduction (or addition) can be selective. By way of example, in the smoke stream of a cigarette, compounds such as those shown below in the following listing can be selectively reduced or eliminated. This table is provided by the United States FDA as an initial established list of harmful and potentially harmful components in tobacco products, including tobacco smoke; the abbreviations in the listing below are chemicals known in the art. In some embodiments, the active particle can reduce or eliminate at least one component selected from the list of components in the smoke below, including any combination thereof.

Activated carbon can be low activity (between about 50% and about 75% CCI4 adsorption) or high activity (between about 75% and about 95% CCI4 adsorption) or a combination of both. In some embodiments, the active carbon may be a nanoscale carbon particle, for example carbon nanotubes of any number of walls, carbon nanohorns, bamboo-like carbon nanostructures, fullerenes and fullerene aggregates and graphene, including graphene with few layers and oxidized graphene. Other examples of such materials include ion exchange resins, desiccants, silicates, molecular sieves, metallocenes, silica gels, metallocene, activated alumina, zeolites, perlite, sepiolite, fuller's earth, magnesium silicate, metal oxides (e.g. , iron oxide and iron oxide nanoparticles such as about 12 nm of Fe3O4), nanoparticles (eg, metal nanoparticles such as gold and silver, metal oxide nanoparticles such as alumina, magnetic, paramagnetic and superparamagnetic nanoparticles such as gadolinium oxide , various iron oxide crystal structures such as hematite and magnetite, gado-nanotubes and endofullerenes such as Gd @ C6o, and core-shell nanoparticles and tunicades such as gold and silver nanolayers, iron oxide nanoparticles and other nanoparticles or microparticles with an outer layer of any of said materials) and any combination of the above (including activated carbon). It should be noted that nanoparticles include nanobars, nanospheres, nano rice, nanowires, nanostars (such as nanotrippodes and nanotetrapods), hollow nanostructures, hybrid nanostructures that are two or more nanoparticles connected as one and not nano particles with ñaño-coatings or thick nano-walls. It should also be noted that nanoparticles include functionalized derivatives of nanoparticles including, but not limited to, nanoparticles that have been functionalized by covalent bond or non-covalent bond, e.g. eg, pile ordering, physisorption, ionic association, van der Waals association and the like. Suitable functional groups may include, among others, fractions comprising amines (1st, 2nd or 3rd), amides, carboxylic acids, aldehydes, ketones, ethers, esters, peroxides, silyles, organosilanes, hydrocarbons, aromatic hydrocarbons and any combination thereof.; polymers; chelating agents such as ethylenediaminetetraacetate, diethylenetriaminepentaacetic acid, triglycolamic acid and a structure comprising a pyrrolo ring and any combination thereof. The functional groups can improve the removal of the smoke components or improve the incorporation of nanoparticles in a porous mass. The ion exchange resins include, for example, a polymer with a main structure, for example styrene-divinylbenzene copolymer (DVB), acrylates, methacrylates, phenol formaldehyde condensates and epichlorhydrin amine condensates; and various electrically charged functional groups attached to the polymer structure. In some embodiments, the active particles are a combination of several active particles. In some embodiments, the porous mass may comprise multiple active particles. In some embodiments, an active particle may comprise at least one element selected from the group of active particles disclosed herein. It should be noted that "element" is used as a general term to describe elements of a list. In some embodiments, the active particles are combined with at least one flavor.

In some embodiments, a mixture of active particles can be used to remove multiple harmful substances from the smoke stream. For example, while it has been shown that activated carbon is successful in removing substances such as formaldehyde and acetone from cigarette smoke, it is ineffective in removing carbon monoxide. However, carbon monoxide can be removed from a gas stream by exposure to iodine pentoxide, a molecular sieve (for example a metallocene), a molecular oxide, a metal catalyst (for example palladium) and the like.

The porous mass is effective when removing the smoke components, for example, those listed above. A porous mass can be used to reduce the supply of certain components of tobacco smoke targets of WHO. For example, a porous mass in which activated carbon is used as active particles can be used to reduce the supply of certain components of tobacco smoke to levels lower than the WHO recommendations. (See table 13, below). In one embodiment, the porous mass, wherein activated carbon is used, has a length in the range of about 4 mm to about 1 1 mm. Components include: acetaldehyde, acrolein, benzene, benzo [a] pyrene, 1,3-butadiene and formaldehyde. The porous mass with activated carbon can reduce acetaldehyde in a smoke stream between about 3.0% and about 6.5% / mm porous mass length; acrolein in a smoke stream between about 7.5% and about 12% / mm porous mass length; benzene in a smoke stream between about 5.5% and about 8.0% / mm porous mass length; benzo [a] pyrene in a smoke stream between about 9.0% and about 21.0% / mm porous mass length; 1, 3-butadiene in a smoke stream between about 1.5% and about 3.5% / mm porous mass length and formaldehyde in a smoke stream between about 9.0% and about 1.0% / mm in length of porous mass. In another example, a porous mass in which the ion exchange resin is used as active particles can be used to reduce the supply of certain components of tobacco smoke to less than WHO recommendations. See table 14, below. In one embodiment, the porous mass, where ion exchange resins are used, has a length in the range of about 7 mm to about 1 mm. Components include: acetaldehyde, acrolein and formaldehyde. In some embodiments, a porous mass of the present invention having an ion exchange resin can reduce: acetaldehydes in a smoke stream between about 5.0% and about 7.0% / mm porous mass length; acrolein in a smoke stream between about 4.0% and about 6.5% / mm porous mass length; and formaldehyde in a smoke stream between about 9.0% and about 11.0% / mm porous mass length.

The porous mass can be made by any suitable means. In some embodiments, this may be a batch process. In others, this can be a continuous process.

In one embodiment of a suitable method, the active particles and the binder particles are mixed together and introduced into a mold. The mold is heated to a temperature at or above the melting point of the binding particles, e.g. eg, in an embodiment between approximately 150 ° C and 300 ° C and is kept at the temperature for a sufficient period to heat the mold and its contents to the desired temperature. Subsequently, the dough is removed from the mold and cooled to room temperature. These methods can be performed in small batches or large batches that may be suitable for commercial production.

In some embodiments, a suitable process may be a free sintering process, since the binder particles do not flow (or flow very little) at the sintering temperature and no pressure is applied to the mixed materials in the mold. In this embodiment, bond points are formed between the active particles and the binder particles. It is believed that this allows the formation of a superior bond and maximizes the interstitial space, while minimizing the blinding of the surface of the active particles by means of the freely flowing molten binder. See also, U.S. Patents 6,770,736, 7,049,382 and 7,160,453, which are incorporated herein by reference.

Alternatively, a porous mass of the present invention can be made by a process comprising sintering under pressure. While the mixture of the active particles and the binder particles is heated (or at a temperature that may be lower, equal to or higher than the melting temperature of the binder particles) a pressure is forced into the mixture to facilitate coalescence of the porous mass .

In addition, in some embodiments, the porous mass can be made through an extrusion sintering process wherein the mixture is heated in a cylinder of the extruder and extruded into the porous mass.

Any suitable method for forming a filter for a smoking device comprising a porous mass of the present invention can be used together with the porous masses. For example, in one embodiment, an apparatus for producing a filter for a smoking device having at least various areas comprising: an area of the container comprising at least several parts of the first filter section; and a second container area comprising at least several pieces of the second filter section, which pieces of the second filter section comprise a porous mass having an active particle and a binder particle, which porous mass has: a charge of active particle of at least about 1 mg / mm, an EPD of about 20 mm of water or less per mm of porous mass; a joining area wherein a piece of the first filter section and a piece of the second filter section are joined; a wrapping area wherein the piece of the first filter section and the piece of the second filter section are wrapped with paper to form a filter for a smoking device and a conveyor for transporting the filter for a smoking device a subsequent area for storage or use. In some embodiments, in this process a filter rod can be formed comprising various filters that when cut can be used to form multiple smoking devices (eg, 4 cigarettes per 1 filter rod).

In some embodiments, filters for smoking devices can be transported directly to a manufacturing line where they will be combined with tobacco columns to form smoking devices. An example of such a method includes a process for producing a smoking device comprising: providing a filter rod comprising at least one filter section comprising a porous mass comprising an active particle and a binder particle; provide a column of tobacco; cutting the filter bar transverse to its longitudinal axis through the center of the bar to form at least two filters having at least one filter section, each filter section comprising a porous mass comprising an active particle and a binder particle and joining at least one of the filters to the tobacco column along the longitudinal axis of the filter and the longitudinal axis of the tobacco column to form at least one smoking device.

In the traditional manufacture of cigarettes, the machines that attach the filter section to the tobacco column, as well as the machines that join the multi-component filter section, tend to compress the sections of the cigarette as they go through the process of Union. In some embodiments, the porous mass of the present invention may be non-compressible or less compressible than a traditional cellulose ace filter section, which can lead to difficulties in some manufacturing processes. In embodiments where ultra high molecular weight polymers are used, for example ultra high molecular weight polyethylene, the porous mass of the present invention tends to be incompressible. In such cases, it may be desirable to wrap or coat the porous mass section with a material that is compressible. The wrapping or coating material is placed along the longitudinal axis of the filter section of the porous mass so that the wrapping material or coating is between the porous mass and the wrapping paper. The wrapping or coating material will be selected to provide the desired compressibility while also exhibiting a relatively high pressure drop so that the smoke entrained through the section is preferably transported through the porous mass instead of the wrapping material or coating or the coating material is greater than the encapsulated pressure drop of the porous mass. In some embodiments, the wrapping material may have an encapsulated pressure drop that is 1% higher than the encapsulated pressure drop of the porous mass, in other embodiments the difference may be 5% higher, 10% more high, 25% higher, 50% higher, 75% higher, 100% higher, 125% higher, 150% higher, 175% higher, 200% higher, 225% higher, 250% higher, 275% higher or 300% higher. One skilled in the art will recognize that the difference in the encapsulated pressure drop between the wrapping material or coating and the porous mass can rise even further as long as the negative user is not affected and as long as the wrapping material or the wrapping material is not affected. Siding continues to provide the desired compressibility. In some embodiments, the wrapping material or coating may comprise cellulose ace, polypropylene, polyethylene, polyolefin tow, polypropylene tow, polyethylene terephthalate, polybutylene terephthalate, randomly oriented ace, paper, corrugated paper, carbon tow, silica , magnesium silicate, nylon, cellulose and any combination of these. In other embodiments, the wrapping or coating material is positioned along the longitudinal axis of the filter section of the porous mass so that the wrapping material or coating is outside the wrapping paper. Those skilled in the art will recognize that the diameter of the porous mass should be selected to compensate for the increase in diameter while adding layers of paper or wrapping or coating materials. The final diameter of the filter must match the diameter of the tobacco column for the step of combining the tobacco filter / column. In other embodiments, the wrapping material or coating is placed along the longitudinal axis of the filter section of the porous mass so that the wrapping material or coating is in direct contact with the porous mass. This configuration can eliminate the use of paper in the sintering process. In other embodiments, filters for smoking devices can be placed in a suitable container for storage until later use. Suitable storage containers include those commonly used in the art of filters for smoking devices that include, among others, boxes, crates, drums, bags, cardboard boxes and the like. It may be necessary to modify the storage and transport containers used with the filter sections of the porous mass of the present invention to account for the presence of the porous mass. As an example, the bars cylindrical and other shaped bars or cigarettes that incorporate the filter sections of the porous mass of the present invention may be larger in weight or more brittle than a cellulose acetate filter section. In addition, due to the active nature of the porous mass, it may be desirable to transport the sections of the porous mass or the cigarettes that incorporate section of the porous mass so that the porous mass is not exposed to environmental contamination.

EXAMPLES In the following example, the effectiveness of a porous mass to remove certain components of cigarette smoke is illustrated. The porous mass was made from 25% by weight of GUR 2105 from Ticona, Dallas, TX and 75% by weight of PICA RC 259 (95% active carbon) from PICA USA, Inc. of Columbus, OH. The porous mass has an empty volume percentage of 72% and an encapsulated pressure drop (EPD) of 2.2 mm water / mm porous mass length. The porous mass has a circumference of approximately 24.5 mm. The carbon RC 259 PICA had an average particle size of 569 microns (μ). The porous mass was made by mixing the resin (GUR 2105) and the carbon (PICA RC 259) and then filling a mold with the mixture without pressure on the hot mixture (free sintering). Then, the mold was heated at 200 ° C for 40 minutes. Subsequently, the porous mass was removed from the mold and allowed to cool. A section of defined length of the porous mass was combined with a sufficient amount of cellulose acetate tow to produce a filter with a total encapsulated pressure drop of 70 mm of water. All smoking trials were conducted in accordance with the standards of the tobacco industry. All cigarettes were smoked using the intense Canadian protocol (ie, T-1 5, "Determination of" Jar, "Nicotine and Carbon Monoxide in Mainstream Tobacco Smoke", Health Canada, 1999) and a Cerulean 450 smoking machine.

TABLE 1 TABLE 2 TABLE 3 In the following example, the effectiveness of a porous mass to remove certain components of cigarette smoke is illustrated. The porous mass was made from 30% by weight of GUR X192 from Ticona, Dallas, TX and 70% by weight of PICA 30x70 (60% active carbon) from PICA USA, Inc. of Columbus, OH. The porous mass has an empty volume percentage of 75% and an encapsulated pressure drop (EPD) of 3.3 mm water / mm porous mass length. The porous mass has a circumference of approximately 24.5 mm. The PICA 30x70 carbon had an average particle size of 405 microns (μ). The porous mass was made by mixing the resin (GUR X192) and the carbon (PICA 30x70) and then filling a mold with the mixture without pressure on the hot mixture (free sintering). Then, the mold was heated at 220 ° C for 60 minutes. Subsequently, the porous mass was removed from the mold and allowed to cool. A section of defined length of the porous mass was combined with a Sufficient amount of cellulose acetate tow to produce a filter with a total encapsulated pressure drop of 70 mm of water. All smoking trials were conducted in accordance with the standards of the tobacco industry. All cigarettes were smoked using the intense Canadian protocol (ie, T-1 5, "Determination of" Tar, "Nicotine and Carbon Monoxide in Mainstream Tobacco Smoke", Health Canada, 1999) and a Cerulean 450 smoking machine.

TABLE 4 TABLE 5 TABLE 6 In the following example, the efficacy of a porous mass of ion exchange resin for removing certain components of cigarette smoke is illustrated. The porous mass was made from 20% by weight of GUR 2105 from Ticona, Dallas, TX and 80% by weight of an amine-based resin (AMBERLITE IRA96RF from Rohm &; Haas of Philadelphia, PA). A 10 mm section of the porous mass was combined with a sufficient amount of cellulose acetate tow (12 mm) to produce a filter with a total encapsulated pressure drop of 70 mm water. All smoking trials were conducted in accordance with the standards of the tobacco industry. All cigarettes were smoked using the intense Canadian protocol (ie, T-115, "Determination of" Jar, "Nicotine and Carbon Monoxide in Mainstream Tobacco Smoke", Health Canada, 1999) and a Cerulean 450 smoking machine.

TABLE 7 In the following example, the effectiveness of a desiccant porous mass for removing water from cigarette smoke is illustrated. The porous mass was made from 20% by weight of GUR 2105 from Ticona, Dallas, TX and 80% by weight of desiccant (calcium sulfate, DRIERITE from W. A. Hammond DRIERITE Co. Ltd. of Xenia, OH). A 10 mm section of the porous mass was combined with a sufficient amount of cellulose acetate tow (15 mm) to produce a filter with a total pressure drop of 70 mm of water. All smoking trials were conducted in accordance with the standards of the tobacco industry. All cigarettes were smoked using the intense Canadian protocol (ie, T-1 15, "Determination of" Jar "Nicotine and Carbon Monoxide in Mainstream Tobacco Smoke", Health Canada, 1999) and a Cerulean 450 smoking machine.

TABLE 8 In the following example, a carbon tow filter element is compared with the novel porous mass. In this comparison, equal total carbon loads are compared. In other words, the amount of carbon in each element is the same; it is allowed to vary the length of the element to obtain equal amounts of carbon. The change in the smoke component is recorded in relation to the conventional cellulose acetate filter (the percent change is relative to a conventional cellulose acetate filter). All the filters consisted of the carbon element and a cellulose acetate trailer. All filters were sucked out with a sufficient length of cellulose acetate filter trailer to obtain a pressure drop of the objective filter of 70 mm of water. The total length of the filter was 20 mm (carbon element and towing element). The carbon was 30x70, 60% active PICA carbon. All cigarettes were smoked using the intense Canadian protocol (ie, T-15, "'Determined from" Jar "Nicotine and Carbon Monoxide in Mainstream Tobacco Smoke", Health Canada, 1999).

TABLE 9 In the following example, we compared a porous mass made with a highly active carbon (95% absorption of CCI4) with a porous mass made with a lower active carbon (60% absorption of CCI4). The combined filters were made using a 10 mm section of i the porous mass plus a sufficient length of cellulose acetate to achieve an objective combined encapsulated pressure drop of 69-70 mm of water. These filters were attached to a commercial tobacco column and smoked in a Cerulean SM 450 smoking machine using the Canadian heavy smoking protocol (ie, T-1 15, "Determination of" Jar, "Nicotine and Carbon Monoxide in Mainstream Tobacco Smoke ", Health Canada, 1999). The high active carbon was PICA RC 259, particle size 20x50, 95% activity (adsorption of CCI4). The low active carbon was PICA PCA, particle size 30x70, 60% activity (adsorption of CCI4). The carbon load of each porous mass element was 18.2 mg / mm, low active carbon and 16.7 mg / mm, high active carbon. The data is recorded compared to a conventional cellulose acetate filter.
