In some embodiments, the filter is either naturally or substantially over time (eg, over about 2 years to about 5 years) in the presence of a catalyst that may be present in the filter portion in some embodiments. Can be disassembled. Also included are papers with fibrous tow and active material (attached or impregnated or incorporated). Such active materials include activated carbon (or activated charcoal), ion exchange resins, zeolites, desiccants, catalysts or other materials adapted to act on tobacco smoke. When used, the void chamber can be filled (or partially filled) with the active ingredient or material incorporating the active ingredient. Such active ingredients include activated carbon (or activated charcoal), ion exchange resins, desiccants or other materials adapted to act on tobacco smoke. Further, the filter portion may be a porous material of binder particles (ie, only binder particles that do not contain any active particles). For example, the porous material that does not contain the active particles is made using thermoplastic particles that are bonded or combined into a porous cylindrical shape (eg, a polyolefin powder containing the binder particles described below). can do.

  In another embodiment, the portion can include a space defined as a cavity between two filter portions (one portion containing the porous material of the present invention). The cavities can be filled with, for example, granular carbon or as another example a flavoring agent. The cavity can contain capsules, such as polymer capsules containing flavorings or catalysts. In some embodiments, the cavities react with selected chemical components in the smoke to remove or reduce the concentration of the chemical component without adversely affecting the desired scent component of the smoke. Can also be contained. In one embodiment, the cavity can include tobacco as an additional flavor. If the cavity is not sufficiently filled with the selected material, in some embodiments, this may result in a lack of interaction between the mainstream smoke chemical components and the material in the cavity and in other filter parts. Note that can occur.

  Flavorings that may be suitable for use in the present invention include any flavorant suitable for use in a smoking device, including those that impart a flavor and / or flavor to the smoke stream. Flavoring agents include, but are not limited to, organic materials (or natural flavoring particles), natural flavoring carriers, artificial flavoring carriers and any combination thereof. Organic materials (or natural flavoring particles) include but are not limited to tobacco, cloves (eg, powdered cloves and clove flowers), cocoa, and the like.

Further, in some embodiments, the porous material of the present invention can include a flavoring agent. The amount included depends on the desired concentration of flavor in the smoke, taking into account the entire filter portion, the length of the smoking device, the type of smoking device, the diameter of the smoking device and other factors known to those skilled in the art.

  The filter rod can be formed by wrapping the part containing the filter with paper. As used herein, the term “paper” refers generically to any wrapping paper used in the manufacture of smoking articles, such as chip paper, plug wrap paper, chip base paper, and the like. Papers suitable for use with the present invention include wood base paper, flax-containing paper, flax paper, functional paper (eg, functionalized to reduce tar and / or carbon monoxide), special marking paper, Includes colored paper and any combination thereof. In some embodiments, the papers can be highly porous, wavy and / or have high surface strength. In some embodiments, the papers can include additives, sizing agents, and / or printability improvers. In some embodiments, the filter rod comprising the porous material of the present invention can have a length of about 80 mm to about 150 mm. During processing, the filter rod can be substantially divided into about 4 or about 6 individual pieces about 5 to about 35 mm in length during the smoking tipping operation. In double or triple filters, each filter can be first cut into pieces and combined with paper and / or charcoal pieces prior to chipping. The filter rod can be glued to the tobacco column with paper or other smoking device to make a finished smoking article. By way of example, in conventional cigarette manufacture, at least three types of paper, plug wrap, cigarette paper and chip paper are used. Plug wrap refers to the paper used to cover the filter portion of the cigarette when making the filter and before being joined to the tobacco column. Cigarette paper refers to the paper used to cover the tobacco column portion of the cigarette when making the tobacco column and prior to joining the filter portion. Finally, chip paper refers to the paper that is used to cover the two parts when the filter part and part of the tobacco column join to form a cigarette. The seams of the various papers used to form the cigarette can be joined using at least one adhesive, and two or more adhesives can be used to form the cigarette. For example, when forming a conventional cellulose acetate filter part, the filter can be fixed to paper using a polyvinyl alcohol adhesive, and a hot melt adhesive can be used on the edge of the paper and packaged Can be held. In addition, starch-based adhesives can be used on cigarette paper to join the edges of the paper. Finally, chip paper is more completely covered, i.e. covered with a hot melt adhesive over most of the surface rather than just the seam area to ensure that the filter and tobacco parts are properly joined. Can do. In cigarette products, vents are created through the chip paper or through both the chip paper and the plug wrap to draw air into the smoke stream.

  In some embodiments, the filter can have a diameter in the range of about 5 mm to about 10 mm and a length of about 5 mm to about 35 mm. In some embodiments, for example, in ultra-fine or ultra-cigarettes, the filter has a diameter in the range of less than 5 mm, such as 3 mm or less, including but not limited to a lower diameter limit of 0.5 mm. In cigar embodiments, the filter can have a diameter of 20 mm or more, eg, about 30 mm, if desired. Similarly, the size of the filter of other smoking devices can vary (e.g., pipes) depending on the intended use and consumer demand.

  In FIG. 4, the pipe 40 has a combustion bowl 42, a mouthpiece 44 and a channel 46 that interconnects the combustion bowl 42 and the mouthpiece 44. Channel 46 includes a cavity 47. The cavity 47 is adapted to receive the filter 48. Filter 48 may be a multi-part filter as described above, or may consist solely of a porous material. The size of the filter can vary based on the dimensions of the cavity 47. In some embodiments, the filter 48 may be removable, replaceable, disposable, reusable and / or disassembleable.

  In the above embodiment, the conventional material and the porous material are “joined”. As used herein, the term “joined” means that the porous material is adjacent (in series) to the tobacco column or another filter portion, and thus the cigarette. When smoking, smoke from the tobacco column needs to pass (eg, continuously) through the porous material to reach the intended recipient (eg, smoker). As described above, the porous material can be joined to the tobacco column by packaging techniques using, for example, paper and / or adhesive. Further, in some embodiments, the porous material can be bonded to the tobacco column using an adhesive, but preferably the adhesive is free of chemical components that interfere with the purpose of the present invention upon combustion.

  As shown in FIGS. 1-3, in some embodiments, the filter portion comprising the porous material and the at least one other filter portion are coaxial, side-by-side, adjacent, and have equal cross-sectional area ( Or substantially equal cross-sectional areas). However, it is understood that the porous material and conventional material need not be joined in this manner, and other possible configurations are possible. In addition, as shown in FIGS. 1-3, while the porous material is very often envisioned to be used in a combined or multi-segmented cigarette filter configuration, the present invention Without being so limited, as described in FIG. 4 above, the smoking article may include only the porous material of the present invention. Further, in some embodiments, as shown in FIG. 1, the porous material is juxtaposed to the tobacco column, although the present disclosure is not so limited. For example, the porous material of the invention can be separated from tobacco by a hollow cavity (eg, a pipe or hookah or a cigarette or a tube or channel in a cigar holder), see, eg, FIG. In other embodiments, the porous material of the present invention can be separated from the tobacco column by a bendable element, allowing the consumer to shape the smoking device.

  In some embodiments, the porous materials of the present invention comprise active particles that bind at least partially in combination with binder particles. See, for example, the photograph of an embodiment of a porous material that is active particles (eg, activated carbon particles) 50 and binder particles 52 in FIG. 54 shows an example of a contact point. Note that in this embodiment (FIG. 5), the binder particles and the active particles are joined at the contact points, the contact points are randomly dispersed throughout the porous material, and the binder particles are in their original physical shape. (Or substantially keep the original shape, eg, less than 10% change (eg, shrinkage) from the original shape). (Active particles and binder particles are described in further detail below). Without wishing to be limited by any theory, it is believed that the contact point is formed when the binder particle is heated to a temperature that is at its softening temperature but not hot enough to actually reach melting. . In some embodiments, the porous materials of the present invention will exhibit minimal encapsulation pressure drop (defined below), but will be constructed to maximize the active particle surface area.

  The active particles and binder particles of the porous material may be in any weight ratio. In some embodiments, the ratio may be from about 1 to about 99% by weight active particles and from about 99 to about 1% by weight binder particles. In some embodiments, the ratio may be from about 25 to about 99% by weight active particles and from about 1 to about 75% by weight binder particles. In some embodiments, the ratio may be about 40 to about 99% by weight active particles and about 1 to about 60% by weight binder particles. In one embodiment of the porous material, the active particles comprise from about 50 to about 99% by weight of the porous material, while the binder particles comprise from about 1 to about 50% by weight of the porous material. In another embodiment, the active particles comprise about 60 to about 95% by weight of the porous material, while the binder particles comprise about 5 to about 40% by weight of the porous material. In yet another embodiment, the active particles comprise from about 75 to about 90% by weight of the porous material, while the binder particles comprise from about 10 to about 25% by weight of the porous material.

  In one embodiment of the porous material, the porous material has a void volume in the range of about 40% to about 90%. In another embodiment, it has a void volume of about 60% to about 90%. In yet another embodiment, it has a void volume of about 60% to about 85%. The void volume is the empty space left after the active particles occupy the space.

  We do not want to be limited to any particular theory to determine the void volume, but in the test, the final density of the mixture is almost entirely governed by the active particles, so the space occupied by the binder particles is this calculation. Seems to indicate that it is not considered. Therefore, in this regard, the void volume is calculated based on the space remaining after the active particles have occupied. In order to determine the void volume, the active particles are first averaged of upper and lower diameters based on the size of the mesh and then the volume (assuming a sphere based on the average diameter) the density of the active material Calculated using The void volume fraction was then calculated as follows:

  In one embodiment, the porous material has an encapsulation pressure drop (EPD) in the range of about 0.10 to about 25 mm of water / mm of porous material length. As used herein, the term “enclosure pressure drop” refers to air passing through the package when the specimen is traversed by air flow under steady state when the volumetric flow rate at the output end is 17.5 ml / sec. This refers to the difference in static pressure between the two ends of the specimen when the specimen is completely enclosed in the measuring device. In this specification, EPD is measured in the CORESTA (“Joint Center for Scientific Research on Tobacco”) recommended method No. 41 dated June 2007. In another embodiment, the porous material of the present invention may have an EPD in the range of about 0.10 to about 10 mm of water / mm of porous material length. In other embodiments, the porous material of the present invention may have an EPD of about 2 to about 7 mm water / mm of porous material length (or 7 mm water / mm of porous material length or less). In order to obtain the desired EPD, the active particles need to have a larger particle size than the binder particles. In one embodiment, the binder particle size: active particle size ratio ranges from about 1: 1.5 to about 1: 4.

  In some embodiments, the porous material of the invention has 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 In combination with the active particle loading of 22 mg / mm, 23 mg / mm, 24 mg / mm or 25 mg / mm, EPD is less than about 20 mm water / porous material mm or less, water 19 mm / porous material mm or less, water 18 mm / porous Material material mm or less, water 17 mm / porous material mm or less, water 16 mm / porous material mm or less, water 15 mm / porous material mm or less, water 14 mm / porous material mm or less, water 13 mm / porous material mm or less, water 12 mm / porous material mm or less, water 11 mm / porous material mm or less, water 10 mm / porous material mm or less, water 9 mm / Porous material mm or less, Water 8 mm / Porous material mm or less, Water 7 mm / Porous material mm or less, Water 6 mm / Porous material mm or less, Water 5 mm / Porous material mm or less, Water 4 mm / Porous material mm Hereinafter, it may have water 3 mm / porous material mm or less, water 2 mm / porous material mm or less, or water 1 mm / porous material mm or less. By way of example, in some embodiments, the porous material can have an active particle loading of at least about 1 mg / mm and an EPD of about 20 mm water / mm of porous material or less. In other embodiments, the porous material can have an active particle loading of at least about 1 mg / mm and an EPD of no more than about 20 mm water / mm porous material, where the active particles are not carbon. In other embodiments, the porous material may have an EPD of 10 mm water / mm porous material combined with active particles comprising at least 6 mg / mm loading of carbon.

  Depending on the method of making the porous material, the porous material can have any desired length. In a batch molding method, for example, the length could be matched to the dimensions of the mold (s) used. Further, in a continuous manufacturing process, the porous material may be a continuous long cylindrical shape of any desired length. In any case, the porous material can be subsequently cut into the desired length or portion. The desired length may depend on the particular application in which the porous material can be used. In one embodiment, the porous material can have a length of about 1 mm to about 35 mm. In another embodiment, the porous material can have a length of about 2 mm to about 30 mm. Further, the porous material can have a length of about 7 mm to about 20 mm.

  The porous material can have any physical shape. The porous material may have a spiral, triangular, disc-shaped or square shape in some embodiments. In one embodiment, the porous material has a cylindrical shape. Mixed shapes of these shapes may be suitable as well. In some embodiments, the porous material can be machined to reduce weight by drilling a portion of the porous material, if desired. In one embodiment, the porous material may have a specific shape in the cigarette or pipe that is adapted to fit within the cigarette holder or pipe so that smoke can reach the consumer through the filter. it can. With respect to previous smoking device filters, when describing the shape of the porous material herein, the shape can be referred to in the diameter or circumference of the cylindrical cross section (the circumference is around a circle). . However, in embodiments where the porous material of the present invention has a shape other than an actual cylindrical shape, the term “perimeter” is used to mean the perimeter of any shape cross section, including a circular cross section. Shall be understood.

  The active particles may be any material adapted to improve the overall smoke flow. Adapted to improve overall smoke flow refers to any material that can remove, reduce, or add to the smoke stream chemical components. Removal or reduction (or addition) may be selective. As an example, compounds such as those shown in the following list can be selectively removed or reduced in a smoke stream from a cigarette. This table is available from the US Food and Drug Administration as the first draft of a list of potentially harmful components of tobacco products, including tobacco smoke, and any abbreviations listed below are It is a known chemical substance. In some embodiments, the active particles can reduce or eliminate at least one chemical component selected from the following list of smoke chemical components and any combination thereof.

An example of the active material is activated carbon (or activated charcoal or activated coal). The activated carbon may be low activity (CCl ₄ adsorption about 50% to about 75%) or high activity (CCl ₄ adsorption about 75% to about 95%) or combinations thereof. In some embodiments, the activated carbon comprises nanoscale carbon particles, such as carbon nanotubes of any wall number, carbon nanohorns, bamboo-like carbon nanostructures, fullerenes and fullerene aggregates, and several layers of graphene and graphene oxide It may be graphene. Other examples of such materials include ion exchange resins, desiccants, silicic acid, molecular sieves, metallocenes, silica gel, metallocene, activated alumina, zeolite, perlite, sepiolite, fuller earth, magnesium silicate, metal oxide ( For example, iron oxide and iron oxide nanoparticles such as about 12 nm Fe ₃ O ₄ ), nanoparticles (eg, metal nanoparticles such as gold and silver, metal oxide nanoparticles such as alumina, magnetism such as gadolinium oxide, etc. , paramagnetic and superparamagnetic nanoparticles, hematite and various crystal structures of iron oxide such as magnetite, Gad nanotubes, Gd @ end fullerenes and gold and silver nanoshells, such as C _60, onion reduction (onionated) iron oxide and the material Other nanoparticles with either outer shell or My There are core shells such as black particles and onionated nanoparticles) and any combination of the above (including activated carbon).

For example, activated charcoal has been shown to be successful in removing substances such as formaldehyde and acetone from cigarette smoke, while being less effective at removing carbon monoxide. However, carbon monoxide can be removed from the gas stream by exposure to iodine pentoxide, molecular sieves (such as metallocene), oxygen molecules, metal catalysts (such as palladium), and the like.

  In one suitable method embodiment, the active particles and binder particles are mixed together and placed in a mold. The mold is heated to the melting point or higher of the binder particles, for example, in one embodiment, from about 150 ° C. to 300 ° C., and the temperature is maintained for a time sufficient to heat the mold and its contents to the desired temperature. Hold. The material is then removed from the mold and cooled to room temperature. These methods can be done in small batches or large batches that can be suitable for commercial manufacturing.

  In some embodiments, a suitable method may be a free sintering method, in which the binder particles do not flow (or only slightly flow) at the sintering temperature and are mixed in the mold. This is because no pressure is applied to the material. In this embodiment, point bonds are formed between the active particles and the binder particles.

  In conventional cigarette manufacture, the machine for joining the filter part to the tobacco column and the machine for joining together the parts of the multi-component filter tend to compress the cigarette part as the joining process proceeds. In some embodiments, the porous materials of the present invention may be less compressible than non-compressible or previous cellulose acetate filter portions, although differences may occur in some manufacturing methods. In embodiments using ultra high molecular weight polymers such as ultra high molecular weight polyethylene, the porous materials of the present invention tend to be incompressible. In such a case, it is desirable to wrap or cover the porous material portion with a compressible material. The wrapping or covering material is positioned along the longitudinal axis of the porous material filter portion such that the wrapping or covering material is between the porous material and the plug wrap paper. The packaging or covering material has a relatively high pressure drop while exhibiting the desired compressibility, i.e. the smoke sucked through the part is rather than the packaging or covering material or packaging material being larger than the porous encapsulation pressure drop. It should be chosen to also show a pressure drop that preferentially moves through the porous material. In some embodiments, the packaging material has a 1% higher encapsulation pressure drop compared to the porous material enclosure pressure drop, and in other embodiments the difference is 5% higher, 10% higher, 25% higher, It may be 50% higher, 75% higher, 100% higher, 125% higher, 150% higher, 175% higher, 200% higher, 225% higher, 250% higher, 275% higher or 300% higher. Those skilled in the art will know that the difference in encapsulation pressure drop between the packaging or covering material and the porous material does not negatively affect the consumer, and as long as the packaging or covering material continues to have the desired compressibility. You will recognize that it can be even higher. In some embodiments, the packaging or coating material comprises cellulose acetate, polypropylene, polyethylene, polyolefin tow, polypropylene tow, polyethylene terephthalate, polybutylene terephthalate, randomly oriented acetic acid, paper, corrugated paper, carbon-on-tow, silica, Magnesium silicate, nylon, cellulose, and any combination thereof can be included. In other embodiments, the packaging or covering material is positioned along the longitudinal axis of the porous material filter portion so that it is outside the plug wrap paper. One skilled in the art will recognize that the diameter of the porous material must be selected to compensate for the increasing diameter as paper or packaging or coating material is added. The final filter diameter should match the diameter of the tobacco column in the filter / tobacco column combination step. In other embodiments, the packaging or covering material is positioned along the longitudinal axis of the porous material filter portion such that the packaging or covering material is in direct contact with the porous material. This configuration can eliminate the use of paper in the sintering process. In other embodiments, the smoking device filter can be placed in a container suitable for storage until next use. Suitable storage containers include those commonly used in the field of smoking article filters, including but not limited to frame boxes, drums, bags, cartons and the like. Storage and transport containers used with the porous material filter portion of the present invention may need to be modified to take into account the presence of the porous material. By way of example, cylindrical and other shaped rods or cigarettes incorporating the porous material filter portion of the present invention may be heavier or more fragile than a cellulose acetate filter portion.
