    Descriptive Report of the Invention Patent for "SMOKING ITEM WITH HEAT RESISTANT MATERIAL". The present invention relates to a smokable item with a heat resistant sheet material. In particular, the heat resistant sheet material can be supplied as an outer packaging for an unburned smokable item or as a filler for any type of smokable item.
    A variety of smokable items in which tobacco is heated instead of being burned has been proposed in the art. The purpose of such heated smokable items is to reduce the known harmful constituents of smoke, produced by the combustion and pyrolytic degradation of tobacco in conventional cigarettes. In heated smokable items, an aerosol is generated by heating an aroma that generates substrate, such as tobacco. Known heated smokeable items include, for example, electrically heated smokeable items and smokeable items, in which an aerosol is generated by transferring heat from a combustible element or from the heat source to a physically separate aerosol forming material. The aerosol forming material can be located inside, around or downstream of the fuel element. During smoking, volatile compounds are released from the aerosol-forming material by transferring heat from the fuel element and they are entrained in the air removed through the smokable item. As the released compounds cool, they condense to form an aerosol that is inhaled by the consumer.
    For example, US-A-4,714,082 describes smokable items that comprise a high density fuel element, a physically separate aerosol generating means and a heat conducting member. The heat conducting member contacts the fuel element and the aerosol generating means around at least a portion of its peripheral surfaces and conducts the heat from the burning fuel element to the aerosol generating means. The heat-conducting member preferably has a recess from the tip of the fuel element which is lit. US-A-5,303,720 describes smokable items that comprise a fuel element, a physically separate aerosol generating means and an insulating member that surrounds at least a portion of the fuel element. The insulating member is formed by a mixture of a fibrous and inorganic material with a fiber pulp based on fibrillated cellulose. US-A-6,095,152 describes smokable items that comprise a source of fuel and an aerosol generator, both extending along the length of a rod of smokable material. The rod of the smokable material is not packed in a non-combustible packaging.
    A particular category of heated smoking items is the distillation-based smoking item. For example, WO-A-2009/022232 describes a smoke-based distillation item comprising a combustible heat source, an aerosol generating substrate downstream of the combustible heat source and a heat conducting element around and in contact with a rear portion of the combustible heat source and an adjacent front portion of the aerosol generating substrate.
    In most known heated smokable items, the aerosol generating substrate is surrounded by an outer packaging. In these heated smokeable items, which comprise a source of combustible heat, the outer packaging may also extend so that it surrounds at least part of the heat source. Typically, the outer packaging is formed by conventional cigarette paper, the type used to surround tobacco and a filter in a conventional fuel cigarette.
    When using a smoking and heated item, the heat source can reach high temperatures. For example, the heat source can reach an average temperature around 500 ° C and in certain cases, the temperature of the heat source can reach up to 800 ° C for a short period of time during the heating cycle.
    It would be desirable to provide a smokable item that comprises an improved sheet material. In particular, it would be desirable to provide a smokable and heated item with an outer packaging made of an improved sheet material, which is resistant to the heat generated by a fuel or a non-combustible heat source, for example, an electrical heat source , while using the smokable item. In addition, it would be desirable to provide a smokable item that includes a sheet material that preserves physical integrity and exhibits minimal discoloration when subjected to the heat from the heat source used in a smoky and heated item. It would be particularly desirable if such a material could have suitable properties to be applied to heated smokable items using an existing apparatus and methods.
    It would also be desirable to provide a smoking, heated or combustible item with a filling paper formed of a sheet material that has the properties described above.
    According to the invention, a smokable item is provided which includes a heat resistant sheet material, the sheet material comprising a fibrous layer formed of cellulose fibers and at least 50 weight percent of an inorganic filler material having a particle size in the range from 0.1 microns to 50 microns, in which the sheet material has a tensile strength of at least 900 N / m. Preferably, the sheet material according to the invention comprises a fibrous layer formed of cellulose fibers and at least 60 weight percent inorganic filler material. Preferably, the sheet material according to the invention has a tensile strength of at least 1300 N / m. The "tensile strength" of a sheet material is a measure of the force required to stretch the material until it breaks. More specifically, tensile strength is the maximum tensile strength per unit width that the sheet material will resist before breaking and is measured in the machine direction of the sheet material. It is expressed in Newtons units per meter of material (N / m). Tests to measure the tensile strength of a sheet material are well known. An appropriate test is described in the International Standard ISO 1924/2 entitled "Paper and cardboard - Determination of tensile properties - Part 2: Method of constant rate of elongation". The test uses a device for tensile testing which is designed to extend a test piece with given dimensions at an appropriate constant rate of elongation and to measure the tensile force and, if necessary, the elongation produced. Each sheet material test piece is attached to two clamps, the separation of which is adjusted at a specified rate. For example, for a test length of 180 mm, the rate is 20 mm per minute. The tensile force is measured as a function of elongation, and the test continues until the test piece breaks. The maximum tensile force is measured, as well as the elongation at break. The tensile strength of the material can be calculated from the following equation, in which S is the tensile strength in N / m, Faith the average tensile strength in Newton and w is the width of the test piece in meters: For the material in heat-resistant foil used in the smokable items of the present invention, it is important that the tensile strength is such that the foil material can be wrapped in conventional paper spools and that it can withstand the stresses and stresses to which it will be subjected during an automated assembly process to form smokable items. For example, it is important that the material has sufficient rolling capacity, so that it can withstand the process by which the sheet material will pass through a series of rollers. A sheet material that has a tensile strength of less than 900 N / m is too fragile to be used in conventional manufacturing processes for the production of smokable items and is therefore unsuitable for use as an outer packaging or wrapping paper. filling in a smokable item.
    Preferably, the tensile strength of the sheet material is not more than 8000 N / m. More preferably, the tensile strength of the sheet material is less than 6000 N / m. This helps to ensure that the sheet material can be efficiently wrapped around a smokable item during manufacture. For example, the tensile strength of the sheet material is preferably between 900 N / m and 8000 N / m, more preferably between 1300 N / m and 6000 N / m. The heat resistant sheet material used in the smokable items of the present invention contains a significantly higher weight percentage of the inorganic filler or pigment material than conventional paper materials. This results in the material being more resistant to heat than conventional cigarette paper, so that it can withstand the high temperatures to which the paper can be subjected during the use of a smokable item, without significant loss of physical integrity. The sheet material used in the smokable items according to the present invention exhibits significantly reduced levels of cracking and carbonization during heating, when compared to conventional cigarette papers and, in addition, it has a lower degree of discoloration. And the inorganic filler material advantageously does not release any unwanted products or by-products during heating and has a negligible effect on the heat transfer in the smokable item, or on the aroma of the volatile compounds distributed to the user. Most importantly, the sheet material used in the smokable items of the present invention also provides surfaces that can be readily printed with good resolution and which can be glued together or to other components of a smokable item. These properties are essential in providing a sheet material that is suitable for use as an outer packaging or filling paper for a smokable item. The heat-resistant sheet material used in these fumes of the present invention is based on a fibrous layer of a material that resembles a type of paper material, however, it has a higher level of inorganic filler than the materials conventional paper. The fibrous layer for use in the smokable item sheet material of the present invention is formed by up to 50% of a suitable cellulose pulp derived from wood, plant or certain grams. Preferably, the fibrous layer is formed by up to 40% of such a suitable pulp material. It is typically advantageous to maximize the average fiber length of the fibers in the cellulose pulp to improve the degree of refining or pulping of the pulp used. i The inorganic filler material constitutes at least 50% by weight of the fibrous layer, more preferably at least 60% by weight, most preferably at least 70% by weight, even more preferably at least 80% by weight . The inorganic filler material is a non-fibrous particle material that comprises substantially spherical shaped particles. The inorganic filler material may comprise a single compound, or a mixture of compounds. Suitable filler compounds for the formation of i-Norwegian filler material include, but are not limited to: calcium carbonate (CaCO3), calcium sulfate (CaSO4), an inorganic material with phase change, for example, aluminum trihydroxide without crystallized water (AI (OH) 3.3H2O), aluminum (III) oxide (AI2O3) and mixtures thereof. The inorganic filler material has a particle size in the range from about 0.1 microns to about 50 microns, preferably in the range from about 0.1 microns to about 30 microns, in a manner most preferred in the range from about 0.3 microns to about 3 microns.
    It has been found that although an increase in the concentration of inorganic filler material above 60% by weight results in a desirable improvement in the heat resistance of the sheet material, this may in some circumstances reduce the tensile strength of the sheet material . Therefore, in most cases it is preferable to include no more than 85 to 90% by weight of inorganic filler material, in order to improve both the heat resistance properties and the tensile strength properties of the inventive sheet material. Preferably, the fibrous layer further comprises a binder material suitable for improving the agglutination of the layer components. Advantageously, a suitable binder does not release a pungent odor or toxic substances due to decomposition when exposed to heat. Preferably, the binder material is an organic binder and can comprise a single organic binder compound, or a mixture of organic binder compounds. The presence of an organic binder material in the sheet material provides advantageous visco-elastic behavior and improved material machinability.
    Suitable organic binder compounds include, but are not limited to: anionic starch, cationic starch, guar gum, xanthan gum, casein, polyvinyl alcohol and mixtures thereof. Preferably, the binder material comprises a naturally occurring organic binder, more preferably a cellulose binder. In a particularly preferred embodiment, the binder material comprises a mixture of anionic starch and guar gum. The amount of binder material can be selected depending on the desired properties of the sheet material used in the smokable items of the invention. Preferably, the binder material constitutes between about 0.1% and about 10% by weight of the fibrous layer, more preferably between about 0.5% and about 5% by weight. If desired, the fibrous layer can further comprise a small percentage of the amounts of additional components. For example, certain constituents such as flocculants, coagulants or other processing aids can be advantageously incorporated, in order to improve the processing of the raw materials for the formation of the fibrous sheet material. An example of a suitable flocculant is polyacrylamide, which is preferably incorporated at levels of less than 0.5% by weight and more preferably less than 0.1% by weight. The fibrous layer preferably weighs between 70 and 130 grams per square meter (gsm) with a preferred weight of 80 grams per square meter (gsm).
    Preferably, the sheet material used in the smokable items according to the present invention still comprises a coating layer on at least one side of the fibrous layer. More specifically, the sheet material can include an inner coating layer, an outer coating layer or both, an inner coating layer and an outer coating layer. The coating layer or layers may partially or completely cover the fibrous layer. The term "inner coating layer" is used to refer to the coating layer that is on the inner surface of the sheet material when the sheet material is packaged around a smokable item. The inner coating layer will therefore typically be in contact with the components of the smokable item that are surrounded by the sheet material.
    On the other hand, the term "outer coating layer" is used to refer to the coating layer that provides the outer surface of the sheet material when the sheet material is wrapped around a smokable item. Therefore, it is more important that the appearance of the outer coating layer is affected as little as possible by heating.
    Preferably, the coating layer or layers comprise an inorganic filler material and a binder material. Preferably, the inorganic filler material constitutes at least 60% by weight of the coating layer, more preferably at least 70% by weight. The inorganic filler material may comprise a single compound inorganic filler material, or a mixture of compounds. Compounds suitable for the formation of inorganic fillers include, but are not limited to, calcium carbonate (CaCO3), aluminum trihydride (AI (OH) 3.3H2O), aluminum (III) oxide (AI2O3), titanium dioxide (TiO2) and clays. Alternatively, the inner coating layer may comprise less or no inorganic filler material and instead be substantially composed of a binder. For example, the inner coating layer can be substantially composed of an impermeable polymer, such as polyvinyl alcohol (PVOH) in order to prevent staining.
    Suitable and preferred binder materials are those identified above. These are organic binders that can comprise a single natural binder compound or a mixture of natural binder compounds. Suitable organic binder compounds include, but are not limited to: anionic starch, cationic starch, anionic starch, guar gum, xanthan gum, casein, polyvinyl alcohol and mixtures thereof.
    Where both an inner coating layer and an outer coating layer are provided, the coating layers may have the same or different compositions, weights and thicknesses.
    Advantageously, it has been found that the provision of an inner coating layer insulates the rest of the sheet material from the heat generated by the heat source. This improves the resistance of the sheet material to the heat it is subjected to when using a smokable item according to the invention, which comprises the sheet material such as the outer packaging or the filling paper. Providing an outer coating layer has been found to reduce discoloration and other visible changes of the outer sheet material during heating.
    Preferably, where a single layer of coating is provided, the weight of the coating layer will be between 5 and 75 grams per square meter (gsm) and where both the inner and outer layers of coatings are provided, the weight of each layer of coating will be at least 10 grams per square meter (gsm), preferably at least 20 grams per square meter (gsm). Preferably, the thickness of each coating layer is between 10 microns and 50 microns, more preferably between 20 and 30 microns. The inner cladding layer or the outer cladding layer, or both the inner cladding layer and the outer cladding layer can be formed of multiple layers, which includes, for example, one or more layers of pre-cladding and a layer top coat over the pre-coat layer or layers. The top coating layer preferably includes a mixture of inorganic filler and binder material, as described above. One or more layers of pre-coating can be added to provide desirable properties for the outer coating layer, the inner coating layer or both. For example, a layer of impermeable polymer, such as polyvinyl alcohol (PVOH) can be provided to prevent oxygen from entering the fibrous sheet material and reduce the likelihood of combustion of the sheet material during heating.
    In addition to the provision of coating layers, or as an alternative, the fibrous layer can be sprayed with a starch solution, which advantageously increases the tensile strength of the resulting sheet material. Where one or more coating layers are provided, the starch is sprayed onto the fibrous layer prior to application of the coating layer or layers.
    Preferably, the total thickness of the heat-resistant sheet material is between 50 microns and 500 microns, more preferably between 70 microns and 200 microns, more preferably between 100 microns and 200 microns. Preferably, the weight of the sheet material is between 70 and 200 grams per square meter (gsm), more preferably between 100 and 200 gsm, more preferably between 120 and 160 gsm. Preferably, the sheet material is white in color and remains white during heating. This can be achieved through an appropriate selection of an inorganic filler material or white-colored binder material in the coating layer or layers. The heat-resistant sheet material used in the smokable items according to the invention is formed primarily by mixing the fibrous cellulose material, the inorganic filler material, the binder and the additive materials, if present, and by mixing with a sheet material using conventional papermaking techniques. Optionally, the resulting sheet material can be sprinkled with starch and then the inner coating layer and the outer coating layer, when present, are deposited on the fibrous sheet material using any suitable deposition technique, such as spraying, dipping or curtain coating. The layers are dried under atmospheric conditions, with no need for additional processing steps, such as pyrolysis or sintering. The sheet material described above finds particular application as an outer packaging for a smokable and heated item according to the invention, which comprises a heat source and an aerosol-generating substrate, since the packages are heat resistant enough to resist the heat generated by the heat source of such smokable items during use. In particular, the outer packaging, formed by the sheet material described, can be advantageously incorporated into the distillation-based smokable items of the construction described in WO-A-2009/022232 which has a heat conducting element in contact with the source of heat and the aerosol generating substrate which, during use, transfers heat from the heat source to the substrate.
    A preferred embodiment of the present invention provides a smoking, heated i-tem comprising a source of combustible heat; an aerosol generating substrate downstream of the combustible heat source; and an outer packaging that surrounds at least a portion of the heat source and the aerosol generating substrate, in which the outer packaging is formed by the heat resistant sheet material described above.
    A variety of heated smokable items, which comprise a source of combustible heat are well known in the art and it would be apparent to a person skilled in the art how to incorporate the outer packaging described above into such smokable items. A particularly suitable smokable and heated item within which an outer packaging of the heat resistant sheet material can be incorporated is the smokable and heated distillation item described in WO-A-2009/022232.
    Suitable fuel sources of heat for use in the heated smokable items according to the invention, and methods for producing such heat sources are well known in the art and described, for example, in US-A-5,040,552, US-A -5,060,676, US-A-5,146,934, US-A-5,188,130, US-A-5,240,014, US-A-5,246,018, US-A-5,247,949, US-A-5,443 .560, US-A-5,468,266 or US-A-5,595,577.
    Other preferred embodiments of the present invention provide an electrically heated aerosol generating system that includes an electric heating element and an aerosol forming substrate, in particular, such electrically heated smoke systems using a continuous heating system. For example, such aerosol generating systems are described in European Patent Application Number 09252687.0 and in European Patent Application Number 09252501.3. The heat-resistant sheet material described above can be used as an external packaging for the aerosol-forming substrate and optionally, other suitable components of the invention, or as a thermally stable carrier, for example, a tubular carrier, for a solid substrate aerosol former. The heat-resistant sheet material described above also finds particular application as a filling paper for a smokable and heated item or a smokable combustible item according to the invention. The term "filler paper" is a well-known term, which is typically used to refer to the paper that covers the filter and connects the filter to the rod of tobacco material, in particular, in a conventional smokable fuel item. In the context of a smoking and heated item, the filling paper connects the nozzle to the contact component upstream of the smoking item. Advantageously, the use of heat-resistant sheet material decreases the likelihood of ignition of the smokable item and, in particular, the portion of the smokable item that is discarded after being smoked. The invention will be described further, by way of example only, with reference to the attached figures, in which: Figure 1 shows a schematic cross-sectional view of a heat-resistant sheet material suitable for use in a smokable item according to the present invention; and figure 2 shows a schematic view of the longitudinal cross section of a smokable and heated item according to the invention, which includes an outer packaging formed by the sheet material of figure 1. The sheet material 10 shown in figure 1 comprises a fibrous base layer 12, inner layer 14 and outer layer 16. The fibrous base layer is formed by the materials shown below in Table 1. TABLE 1 Each inner layer 14 and each outer layer 16 they are formed by the materials shown below in Table 2: TABLE 2 The thickness of each coating layer is 20 microns and each layer is 20 grams per square meter (gsm) in weight. The total thickness of the outer packaging is 140 microns and the total weight is 140 grams per square meter (gsm). The cigarette-type smokable item 20 according to the invention and shown in figure 2 comprises a combustible heat source 22, an aerosol generating substrate 24, an elongated expansion chamber 26 and a nozzle 28 in coaxial contact alignment. All components enclosed in an outer package 30 formed by the sheet material 10 shown in figure 1. The combustible heat source 22 is a carbon-based heat source with a pyrolyzed pore. The combustible heat source 22 is cylindrical and comprises a central airflow channel 32 that extends longitudinally through the combustible heat source 22. A substantially air-resistant heat-resistant coating 34 of iron oxide is provided on the internal surface of the central airflow channel 22. The aerosol generating substrate 24 is located immediately downstream of the combustible heat source 22 and comprises a cylindrical plug of homogenized tobacco material 36 which comprises glycerin as the aerosol former and which is surrounded by the filter plug housing 38. The homogenized tobacco material 36 consists of longitudinally aligned filaments of extruded tobacco material.
    A heat conducting element 40 consisting of an aluminum foil tube surrounds and is in contact with a rear portion 22b of the combustible heat source 22 and a front contact portion 24a of the aerosol generating substrate 24. As shown in figure 2 , a rear portion of the aerosol generating substrate 24 is not surrounded by the heat conducting element 40. The elongated expansion chamber 26 is located downstream of the aerosol generating substrate 24 and comprises a cylindrical tube with an open end of the cardboard 42. The nozzle 28 of smokable item 20 is located downstream of expansion chamber 26 and comprises a cylindrical cellulose acetate hemp fiber plug 44 with very low filtering efficiency, surrounded by the filter plug housing 46. The nozzle 28 can be surrounded by the filler paper (not shown).
    A smokable item that has a similar construction is described in WO-A-2009/022232, which also describes how the components of the smokable item are produced and assembled. The sheet material can be applied to a smokable item using known machinery and processes.
    It will be understood that while in the smokable item described above, a variety of components are provided in addition to the heat source and the aerosol-generating substrate, the sheet material would also be suitable for any type of smoky and heated item that comprises a heat source and an aerosol generating substrate.
