    [001] The present invention relates to a paper wrapper for an electrically heated aerosol generating article, an electrically heated aerosol generating article comprising the paper wrapper, and the use of the paper wrapper in the manufacture of an aerosol generating article. electrically heated.
    [002] One type of aerosol generating system is an electrically operated smoking system. Known electrically operated portable smoking systems typically comprise an aerosol generating device comprising a battery, control electronics and an electrical heater for heating an aerosol generating article specifically designed for use with the aerosol generating device. In some examples, the aerosol generating article comprises a plug of an aerosol generating substrate, such as a tobacco plug, and the heater contained within the aerosol generating device is inserted into the aerosol generating substrate when the aerosol generating article is inserted into the aerosol generating device.
    [003] However, in some cases, the consumer may have difficulty removing the aerosol generating article from the aerosol generating device after use. For example, in some cases an outer shell of the aerosol generating article may tear upon removal of the aerosol generating article from the aerosol generating device, which may contaminate the interior of the aerosol generating device with portions of the shell and portions of the aerosol generating substrate. .
    [004] Accordingly, it would be desirable to provide a wrapper for an electrically heated aerosol generating article that facilitates the removal of the aerosol generating article from an aerosol generating device. It would be particularly desirable to provide such a wrapper that minimizes the risk that the wrapper will tear when removing the aerosol generating article from the aerosol generating device.
    [005] In accordance with a first aspect of the present invention, there is provided a heated aerosol generating article comprising an aerosol generating substrate, a mouthpiece, and a paper wrapper that surrounds at least a portion of the aerosol generating substrate. The aerosol generating substrate comprises at least a first aerosol former in an amount of from about 5 percent to about 30 percent by weight of the aerosol generating substrate. The paper wrapper has a wet tensile strength of at least about 5 Newtons per 15 millimeters when measured according to the wet tensile strength test.
    [006] In accordance with a second aspect of the present invention there is provided a paper wrapper for an electrically heated aerosol generating article, the paper wrapper having a wet tensile strength of at least about 5 Newtons per 15 millimeters when measured from according to wet tensile strength test.
    [007] The wet tensile strength test measures the tensile strength of a wet sheet material and is described in this document in the test methods section.
    [008] As used herein, the term "aerosol generating article" refers to an article comprising an aerosol forming substrate which, when heated, releases volatile compounds that can form an aerosol. Aerosols generated from the aerosol generating substrates of smoking articles according to the invention may be visible or invisible and may include vapors (e.g. fine particles of substances which are in a gaseous state and which are normally liquid or solid at room temperature), as well as gases and liquid droplets from condensed vapors.
    [009] The present inventors have recognized that electrically heated aerosol generating articles typically comprise an aerosol generating substrate, having a higher moisture content when compared to the tobacco column of a conventional cigarette, for example. The inventors have further recognized that the higher moisture content can significantly wet conventional paper wrappers of known electrically heated aerosol generating articles when heated in an aerosol generating device, which can significantly weaken the paper wrapper and cause it to tear. when the aerosol generating article is removed from the aerosol generating device. However, the present invention addresses this problem by providing a paper wrapper having a wet tensile strength of at least about 5 Newtons per 15 millimeters when measured in accordance with the wet tensile strength test.
    [0010] In preferred embodiments, the paper wrapper also has a dry tensile strength of at least about 10 Newtons per 15 millimeters when measured in accordance with the dry tensile strength test set forth in the Test Methods section. Advantageously, providing the inventive wrapper with a tensile strength of at least about 10 Newtons per 15 millimeters can minimize or eliminate the need to modify the manufacture of machines for assembling electrically heated aerosol generating articles by providing of the wrapper with a dry tensile strength that is substantially the same as the dry tensile strength of existing conventional paper wrappers.
    [0011] The aerosol generating substrate preferably comprises liquid and solid components. The aerosol forming substrate may comprise an aerosol forming material not containing tobacco. Alternatively, the aerosol-forming substrate may comprise a tobacco-free aerosol-generating material.
    [0012] The aerosol generating substrate comprises at least one aerosol former in an amount of between about 5 percent and about 30 percent by weight of the aerosol generating substrate, preferably between about 10 percent and 30 weight percent of the aerosol generating substrate, more preferably between about 10 percent and about 20 weight percent of the aerosol generating substrate. An aerosol former is a substance that generates an aerosol upon heating.
    [0013] The aerosol former may include at least one of a polyol aerosol former and a non-polyol aerosol former. It can be a solid or liquid at room temperature, but is preferably a liquid at room temperature. Suitable polyols include sorbitol, glycerol and glycols such as propylene glycol or triethylene glycol. Suitable non-polyols include monohydric alcohols such as menthol, high boiling hydrocarbons, acids such as lactic acid, and esters such as diacetin, triacetin, triethyl citrate or isopropyl myristate. Aliphatic carboxylic acid esters such as methyl stearate, dimethyl dodecanedioate and dimethyl tetradecanedioate can also be used as aerosol forming agents. A combination of aerosol formers, in equal or different proportions, may be used. Polyethylene glycol and glycerol may be particularly preferred, while triacetin is more difficult to stabilize and may also need to be encapsulated to prevent its migration into the aerosol generating article. Examples of suitable aerosol formers are glycerin and propylene glycol.
    [0014] In any of the embodiments described above, the aerosol generating substrate may include water in an amount of between about 10 percent and about 20 percent by weight of the aerosol generating substrate.
    [0015] The at least one aerosol forming substrate may include one or more flavoring agents, such as cocoa, licorice, organic acids or menthol. The at least one aerosol forming substrate may comprise a solid substrate. The solid substrate may comprise, for example, one or more of: powder, granules, pellets, fragments, pieces, strips or leaves containing one or more of: herb leaf, tobacco leaf, tobacco twig fragments, tobacco reconstituted tobacco, homogenized tobacco, extruded tobacco and expanded tobacco. Optionally, the solid substrate may contain additional tobacco-flavored or non-tobacco volatile compounds to be released upon heating the substrate. Optionally, the solid substrate may also contain capsules which, for example, include additional tobacco flavored or tobacco-free volatile compounds. Such capsules may melt during heating of the solid aerosol generating substrate. Alternatively or additionally, such capsules may be crushed before, during or after heating the solid aerosol generating substrate.
    [0016] When the at least one aerosol generating substrate comprises a solid substrate comprising homogenized tobacco material, the homogenized tobacco material may be formed by agglomeration of particulate tobacco. The homogenized tobacco material may be in the form of a sheet. As used herein, the term "sheet" means a laminar element having a length and width substantially greater than the thickness thereof. Sheets of homogenized tobacco material may be formed by agglomerating particulate tobacco obtained by grinding or otherwise comminuting the tobacco leaf blade and/or tobacco leaf stems; alternatively or additionally, the sheets of homogenized tobacco material may comprise one or more of tobacco powder, fine tobacco particles and other particulate tobacco by-products formed during, for example, the treatment, handling and transport of tobacco. Sheets of the homogenized tobacco material may comprise one or more intrinsic binders, i.e., endogenous tobacco binders, one or more extrinsic binders, i.e., exogenous tobacco binders, or a combination thereof to help agglomerate the particulate tobacco. . Alternatively or in addition, the sheets of homogenized tobacco material may comprise other additives, including, but not limited to, tobacco and non-tobacco fibers, aerosol formers, wetting agents, plasticizers, flavoring agents, fillers, aqueous solvents and non-aqueous and combinations thereof. Sheets of homogenized tobacco material are preferably formed by a casting process of the type which generally comprises casting a slurry comprising particulate tobacco and one or more binders on a mat or other support surface, drying the slurry for forming a sheet of homogenized tobacco material and removing the sheet of homogenized tobacco material from the backing surface. The aerosol forming substrate may comprise a bundled sheet of homogenized tobacco material. As used herein, the term "bundled" is used to describe a sheet that is twisted, folded, compressed or constrained substantially transversely to the longitudinal axis of the aerosol generating article. Additionally or alternatively, the sheet of homogenized tobacco material may be crimped. As used herein, the term "crimped sheet" denotes a sheet having a plurality of substantially parallel edges or corrugations. Preferably, when the aerosol generating article has been assembled, the substantially parallel edges or corrugations will extend along or parallel to the longitudinal axis of the aerosol generating article.
    [0017] Optionally, the solid substrate can be supplied or incorporated into a thermally stable carrier. The carrier may be in the form of powder, granules, pellets, filaments, pieces, strips or sheets. Alternatively, the carrier may be a tubular carrier with a thin layer of the solid substrate deposited on its inner surface, such as that disclosed in US-A-5 505 214, US-A-5 591 368 and US-A-5 388 594 , or on its outer surface, or on both its inner and outer surfaces. Such a tubular carrier may be formed, for example, of a paper or paper-like material, a non-woven carbon fiber mat, a low mass open mesh wire mesh, a perforated metal sheet or any other thermally stable polymeric matrix. . The solid substrate may be deposited on the surface of the carrier in the form of, for example, a sheet, foam, gel or slurry. The solid substrate may be deposited over the entire surface of the carrier, or alternatively, it may be deposited in a pattern to provide a predetermined or non-uniform aroma distribution during use. Alternatively, the carrier may be a bundle of non-woven fabric or fibers into which tobacco components have been incorporated, as described in EP-A-0 857 431. The non-woven fabric or bundle of fibers may comprise, for example, fibers carbon, natural cellulose fibers or cellulose-derived fibers.
    [0018] In any of the embodiments described above, the paper wrapper may enclose only the aerosol generating substrate. Alternatively, the paper wrapper may encircle the aerosol generating substrate and the mouthpiece to secure the mouthpiece to the aerosol generating substrate.
    [0019] The aerosol generating substrate may comprise one or more additional components positioned between the aerosol generating substrate and the mouthpiece, such as a hollow tube, for example a hollow tube acetate, to allow the aerosol generated by the aerosol generating substrate aerosol cool before reaching the mouthpiece for delivery to the consumer. In such embodiments, comprising one or more additional components positioned between the aerosol generating substrate and the mouthpiece, the paper wrapper preferably encloses the one or more additional components.
    [0020] In any of the embodiments described above, the mouthpiece may include a filter. The filter may be formed from one or more suitable filter materials. Many of these filter materials are known in the art. In one embodiment, the mouthpiece comprises a filter formed from cellulose acetate fibers.
    [0021] The mouthpiece can be between about 5 millimeters and about 14 millimeters in length. In one embodiment, the nozzle may have a length of approximately 7 millimeters.
    [0022] The aerosol generating article may be substantially elongated. The aerosol generating article may be substantially cylindrical in shape.
    [0023] The aerosol generating substrate can be substantially elongated. The aerosol generating substrate may be substantially cylindrical in shape.
    [0024] The aerosol generating article may have an overall length of between approximately 30 millimeters and approximately 100 millimeters. In one embodiment, the aerosol generating article has an overall length of approximately 45 millimeters.
    [0025] The aerosol generating article may have an outside diameter of between approximately 5 millimeters and approximately 12 millimeters. In one embodiment, the aerosol generating article may have an outside diameter of approximately 7.2 millimeters.
    [0026] The aerosol generating substrate may have a length of between approximately 7 millimeters and approximately 15 mm. In one embodiment, the aerosol generating substrate may have a length of approximately 10 millimeters. In an alternative embodiment, the aerosol generating substrate may have a length of approximately 12 millimeters.

    [0028] The aerosol generating substrate may have an outside diameter of between approximately 5 millimeters and approximately 12 millimeters. In one embodiment, the aerosol generating substrate may have a length of approximately 7.2 millimeters.
    [0029] The present invention also extends to the use of the paper wrapper in the manufacture of an electrically heated aerosol generating article in accordance with any of the embodiments described above. Therefore, in accordance with a third aspect, the present invention provides the use of a paper wrapper in the manufacture of an electrically heated aerosol generating article, the paper wrapper having a wet tensile strength of at least about 5 Newtons. by 15 millimeters when measured according to the wet tensile strength test. Preferably, the paper wrapper further comprises a dry tensile strength of at least about 10 Newtons per 15 millimeters when measured in accordance with the dry tensile strength test. Test Methods Dry Tensile Strength Test
    [0030] The dry tensile strength test (ISO 1924-2) measures the tensile strength of a paper sample conditioned under dry conditions. Material and Equipment: • Tensile/Compression Testing Machine, Instron 5566 or universal equivalent • 100 Newtons tension load cell, Instron or equivalent • Two pneumatically actuated grippers • One 180 ± 0.25 gauge steel block mm long (width: ~10 mm, thickness: ~3 mm) • Double-blade strip cutter, size 15 ± 0.05 x ~ 250 mm, available from Adamel Lhomargy or equivalent • Scalpel • Computer running acquisition software , Merlin or equivalent • Compressed air Sample preparation: • Condition the paper material for at least 24 hours at 22 ± 2 degrees Celsius and 60 ± 5% relative humidity before testing. • Cut the steering sample to the following dimensions: ~ 250 x 15 ± 0.1 millimeters with the double-blade strip cutter. The edges of the test pieces must be cut cleanly - do not cut more than three specimens for analysis at the same time Instrument Setup: • Install the 100 Newtons Tensile Load Cell • Power on the Universal Tensile/Testing Machine Compression and the computer • Select the measurement method preset in the software (test speed set to 8 millimeters per minute) • Calibrate the tension load cell • Install the pneumatically operated jaws • Adjust the test distance between the jaws pneumatic action to 180 ± 0.5mm through steel gauge block • Set distance and force to zero Test Procedure: • Place test specimen straight and center between grips, avoid touching area to be be tested with your fingers. • Close the upper jaw and leave the paper strip hanging from the open lower jaw. • Set force to zero. • Pull the paper strip slightly and then close the lower grip, keeping the force on the test specimen - the starting force should be between 0.05 and 0.20 Newtons. • Start measurement. While the gripper is moving upward, a gradually increasing force is applied until the test specimen breaks. • Repeat the same procedure with the remaining test specimens. Note: The result is valid when the specimen breaks at a distance of more than 10 millimeters from the jaws. If not, reject this result and carry out an additional measurement.
    [0031] Figure 1 illustrates the measurement principle and the relevant dimensions of the specimen before testing and when stretched during testing.
    [0032] Figure 2 illustrates a typical force/elongation curve obtained for a single test specimen and the relevant formulas for calculating the tensile strength and elasticity at rest. Wet tensile strength test
    [0033] The wet tensile strength test measures the tensile strength of a paper sample conditioned under wet conditions. The test is identical to the dry tensile strength test, except for the addition of 2 microliters of liquid to the sample after conditioning for at least 24 hours at 22 ± 2 degrees Celsius and 60 ± 5% relative humidity and after cutting. the size sample. The 2 microliters of liquid are applied with a syringe to the center of the test sample, just before the draw step of the test procedure. Burst Test
    [0034] The burst test tests an aerosol generating article comprising an outer paper wrapper to a complete heating cycle in the appropriate aerosol generating device, without gulps, followed by extraction of an aerosol generating article from the aerosol generating device . The test is repeated for a number of identical aerosol generating articles and the percentage of aerosol generating articles exhibiting a break in the outer paper wrapper is determined by a visual inspection. Smoking Test
    [0035] To determine the composition of the aerosol generated by an aerosol generating article, the aerosol generating article is subjected to a heating cycle in the appropriate aerosol generating device under the Health Canada smoking regimen (12 puffs with a puff volume 55 ml, 2 second drag duration and 30 second drag interval). Example
    [0036] A number of reference aerosol generating articles were constructed using an outer casing formed from a conventional paper casing and a number of test aerosol generating articles were constructed. The test aerosol generating articles were constructed identically to the reference aerosol generating articles, except for the outer wrapper, which was formed from a paper in accordance with the first aspect of the present invention. The paper used for test aerosol generating articles is available from Delfortgroup AG under product code CP. A646.
    [0037] The conventional paper (standard paper) used to construct the reference articles and the test paper (RD paper) used to construct the test articles were both subjected to the Dry Tensile Strength Test and the results are recorded in Figure 3. The results show that the conventional paper and the test paper have substantially the same dry tensile strength, which advantageously allows the use of the test paper in the construction of aerosol generating articles without the need to substantially modify the fabrication. of existing machines and processes.
    [0038] Test and conventional papers were also subjected to three separate Wet Tensile Strength Tests: addition of 2 microliters of water (results recorded in Figure 4); addition of 2 microliters of glycerin (results recorded in Figure 5); and adding 2 microliters of a 1:1 mixture of water and glycerin (results recorded in Figure 6). The results of the Wet Tensile Test show that the test paper exhibited significantly higher wet tensile strength when compared to conventional paper. In the test in which a mixture of water and glycerin was added to the papers, which most closely resembles the moisture of a typical aerosol generating substrate in an electrically heated article, the test paper exhibited a wet tensile strength nearly 8 times greater than the wet tensile strength of conventional paper.
    [0039] The increased wet tensile strength of the test paper is also evident in the burst test results, where a number of each of the reference articles and the test articles were subjected to the burst test. Specifically, reference articles constructed with the conventional paper exhibited breakage in approximately 59 percent of the articles tested, whereas none of the test articles constructed with the test paper exhibited any breakage of the paper wrapper.
    [0040] Finally, the reference articles constructed with the conventional paper and the test articles constructed with the test paper were both smoked according to the Smoking Test and the results recorded in Figure 7. The results show that the replacement of the conventional paper with the test paper did not create any significant change in the composition of the aerosol delivered from the aerosol generating article.
