Description

Technical Field

[0001] This disclosure relates to methods, tools, and components for removing a sensor heating element from an aerosol-generated article. Background Technology

[0002] Some aerosol generation systems include an aerosol generation apparatus having an induction heating element and a cavity configured to receive an aerosol-generated article. The aerosol-generated article includes an aerosol-forming matrix and a sensor heating element. The sensor heating element is positioned such that when the aerosol-generated article is received in the cavity, the induction heating element of the aerosol generation apparatus can heat the sensor heating element. Heating of the sensor heating element causes heating of the aerosol-forming matrix to generate an aerosol.

[0003] Removing the sensor heating element from an aerosol-generating article can be challenging. Since the sensor heating element is typically located within the aerosol-generating article, access to its interior may be required. In some cases, the sensor heating element may be embedded within the aerosol-forming matrix. Summary of the Invention

[0004] According to various aspects of the invention, an assembly is provided that facilitates the removal of a receptor heating element from an aerosol-generating article. The assembly includes a cutting tool. The cutting tool includes a body defining a passage through which the aerosol-generating article can pass, and the cutting tool includes a cutting element extending into the passage. The cutting element includes a cutting blade arranged to cut the aerosol-generating article as it passes through the passage. The assembly also includes a heating element removal tool including a tip configured to magnetically attract the receptor heating element and remove the heating element from the aerosol-generating article that has been cut by the cutting tool when the tip is placed near the receptor heating element.

[0005] The use of components allows for the recovery and reuse of receptor heating elements. In some aerosol-generating articles that include receptor heating elements, the receptor heating element may be the sole non-biodegradable element or one of a limited number of non-biodegradable elements. Therefore, the removal and reuse of receptor heating elements may be environmentally beneficial.

[0006] Furthermore, recycling the sensor heating element may be advantageous, as the sensor material can be a valuable resource. Recycled sensor heating elements can be used in any suitable manner. For example, recycled sensor heating elements can be reused, recycled, or the components can be recovered.

[0007] The components of this invention can be advantageously arranged to allow safe cutting of aerosol-generating articles. For example, the cutting edge of the cutting element can be positioned within a passageway. This positioning prevents accidental contact with the cutting edge of the cutting element by the user.

[0008] The heating element removal tool can be held relative to the passageway of the cutting tool. This arrangement may be convenient for consumers. For example, when the heating element removal tool is held relative to the passageway of the cutting tool, the space occupied by the component can be reduced compared to storing each tool separately. Holding the heating element removal tool relative to the cutting tool also allows the tools to be stored together so that both tools are available when the consumer needs them.

[0009] According to various aspects of the present invention, a tool is provided to facilitate the removal of a receptor heating element from an aerosol-generating article. The tool includes a body defining a passage through which the aerosol-generating article can pass. The tool also includes a cutting element extending into the passage. The cutting element includes a cutting blade arranged to cut the aerosol-generating article as it passes through the passage. The cutting element includes a magnet and is configured to magnetically attract the receptor heating element.

[0010] The cutting element can be configured to be inserted into and removed from the passage. The sensor heating element can be removed from the passage when the cutting element is removed and the sensor heating element is magnetically attracted to the cutting element. The removed sensor heating element can be recycled.

[0011] The tool of the present invention can be advantageously arranged to allow safe cutting of aerosol-generating articles. For example, the cutting edge of the cutting element can be positioned within a passageway to cut the aerosol-generating article. This positioning prevents accidental contact with the cutting edge of the cutting element by the user when the tool is in use.

[0012] According to various aspects of the present invention, a method for removing a receptor heating element from an aerosol-generating article is provided. The method includes passing the aerosol-generating article through a passage of a cutting tool. The cutting tool includes a body defining the passage and includes a cutting element extending into the passage. The cutting element includes a cutting blade arranged to cut the aerosol-generating article as it passes through the passage. The method includes removing the receptor heating element from the cut aerosol-generating article. The removed receptor heating element can be recovered.

[0013] The tools and components of this invention can be used to perform the methods of this invention.

[0014] The methods, tools, and components of this invention can be used to remove a sensor heating element from any suitable aerosol generating article. The aerosol generating article can have any suitable size and shape. For example, the aerosol generating article can be formed into an elongated cylindrical strip. The aerosol generating article may include an oral end and a distal end upstream of the oral end. In use, a user can aspirate through the oral end to inhale the aerosol generated by the aerosol generating article. The aerosol generating article may include an aerosol forming matrix positioned at or toward the distal end.

[0015] The aerosol forming matrix can be solid, liquid, or may include both solid and liquid components. Preferably, the aerosol forming matrix includes nicotine. In some preferred embodiments, the aerosol forming matrix includes tobacco. For example, the aerosol forming matrix may include homogeneous tobacco sheets. The aerosol forming matrix may also include tobacco-free aerosol forming materials. For example, the aerosol forming material may include sheets comprising nicotine salts and aerosol forming agents.

[0016] The aerosol forming matrix can be in the form of a rod, the rod comprising an aerosol forming material surrounded by paper or other packaging.

[0017] The aerosol generating article includes a sensor heating element arranged to sufficiently heat the aerosol forming matrix to generate an aerosol when heated by a sensor of an aerosol generating device. Preferably, the sensor heating element, the aerosol generating device, or the sensor heating element and the aerosol generating device are configured such that the sensor heating element sufficiently heats the aerosol forming matrix to generate an aerosol without burning the aerosol forming matrix.

[0018] The sensor heating element is in thermal contact with the aerosol forming matrix. The sensor element can be in direct physical contact with the aerosol forming matrix. The sensor heating element can be embedded in the aerosol forming matrix or external to it. Preferably, the sensor heating element is embedded in the aerosol forming matrix. When embedded in the aerosol forming matrix, the sensor heating element can be positioned along the longitudinal axis of the aerosol forming matrix, or offset from the longitudinal axis of the aerosol forming matrix.

[0019] The sensor heating element can be in the form of a substantially rectangular, thin, elongated component. The sensor heating element can be sheet-like. The sensor heating element can extend within the article of manufacture along any suitable portion of the length of the aerosol-forming matrix. For example, the sensor heating element can extend within the article of 60% or more of the length of the aerosol-forming matrix.

[0020] The sensor heating element can comprise any material that can be inductively heated to a temperature sufficient to generate aerosols from the aerosol forming matrix. For example, the sensor heating element can comprise a metal or carbon. The sensor heating element can comprise a ferromagnetic material. Ferromagnetic materials can comprise ferritic iron, ferromagnetic steel, or stainless steel. The sensor heating element can comprise aluminum.

[0021] The sensor heating element may include a non-metallic core having a metallic layer disposed thereon. For example, the sensor heating element may include metal tracks formed on the surface of a ceramic core.

[0022] The sensor heating element may include a protective outer layer. For example, the sensor heating element may include a protective ceramic layer or a protective glass layer encapsulating the sensor material. The sensor heating element may include a protective coating formed of glass, ceramic, or inert metal on the core of the sensor material.

[0023] At least a portion or component of the sensor heating element is magnetically attractive.

[0024] Aerosol-generating articles may include a single receptor heating element or more than one receptor heating element. If an aerosol-generating article includes more than one receptor heating element, the methods, tools, and components described herein can be used to recover more than one receptor heating element from the aerosol-generating article.

[0025] Aerosol-generating articles may include support elements. The support elements may be located downstream of the aerosol-forming matrix. The support elements may be adjacent to the aerosol-forming matrix. The support elements may include hollow tubular elements. In a preferred embodiment, the support element includes a hollow cellulose acetate tube or a cardboard tube.

[0026] The aerosol generating article may include an aerosol cooling element. The aerosol cooling element may be located downstream of the aerosol forming matrix. The aerosol cooling element may be located downstream of a support element. The aerosol cooling element may be adjacent to the support element. The aerosol cooling element may function as a heat exchanger. Preferably, the aerosol cooling element has sufficient surface area and thermal conductivity to cool the heated aerosol generated from the aerosol forming matrix. Preferably, the aerosol cooling element substantially does not affect the suction resistance of the aerosol generating article. The aerosol cooling element may include a plurality of longitudinally extending channels. The aerosol cooling element may include polylactic acid.

[0027] The aerosol generating article may include a mouthpiece. The mouthpiece may be located at the opening of the aerosol generating article. In some preferred embodiments, an aerosol cooling element is located between a support element and the mouthpiece. The mouthpiece may include a filter. The filter may include cellulose acetate.

[0028] Aerosol-generating articles may include a housing in which components, such as an aerosol-forming matrix and sensor heating element, a support element, an aerosol cooling element, and a mouthpiece, are disposed. The housing may include packaging that surrounds the components of the aerosol-generating article. The packaging may be formed of any suitable material. For example, the packaging may include cigarette paper.

[0029] Aerosol-generated articles can have any suitable total length. For example, the length of an aerosol-generated article can range from 30 mm to 100 mm, preferably between 30 mm and 60 mm.

[0030] The aerosol generating article can have any suitable outer diameter. Preferably, the outer diameter of the aerosol generating article is suitable for the distal end of the aerosol generating article to be received in the cavity of an electrically operated aerosol generating device. In some embodiments, the outer diameter of the aerosol generating article is from 5 mm to 12 mm, preferably between 6 mm and 8 mm.

[0031] The cutting tool of the present invention includes a body defining a passage through which an aerosol-generating article can pass. For example, the inner diameter of the cutting tool defined by the passage may be larger than the outer diameter of the aerosol-generating article. Preferably, the inner diameter of the cutting tool is not significantly larger than the outer diameter of the aerosol-generating article. For example, the inner diameter of the cutting tool may be less than 5 mm larger than the outer diameter of the aerosol-generating article, or less than 2 mm larger than the outer diameter of the aerosol-generating article, or less than 1 mm larger than the outer diameter of the aerosol-generating article, or less than 0.5 mm larger than the outer diameter of the aerosol-generating article. In some preferred embodiments, the inner diameter defined by the passage of the cutting tool is from 5 mm to 15 mm, for example from 7 mm to 10 mm.

[0032] The inner diameter defined by the passage of the cutting tool can be uniform or can vary along its length. Preferably, the inner diameter defined by the passage of the cutting tool is uniform or substantially uniform over 50% or more of the length of the passage, for example, over 80% or more of the length of the passage. For example, the inner diameter defined by the passage of the cutting tool can be considered substantially uniform if it varies by 10% or less along its length, or by 5% or less along its length. By having a substantially uniform inner diameter, particularly if the inner diameter of the passage is similar to the outer diameter of the aerosol-generating article, the passage can provide stability for cutting the aerosol-generating article through the passage.

[0033] The cutting tool may include an inlet funnel having an opening communicating with a passage. For example, the inlet funnel may form a chamfered inlet into the passage. The chamfered inlet helps guide the aerosol-generating article into the passage. The cutting tool may include more than one inlet funnel. For example, the cutting tool may include inlet funnels communicating with each end of the passage.

[0034] The passage of the cutting tool can have any suitable length. Preferably, the passage has a length shorter than the length of the aerosol-generating article. Preferably, the length of the passage allows the aerosol-generating article to be pushed into the passage from one end and pulled out from the passage from the opposite end. For example, the passage may have a length less than 80% of the length of the aerosol-generating article (e.g., less than 50% or less than 20% of the length of the aerosol-generating article).

[0035] The length of the aerosol-generating article used in conjunction with the cutting tool may be 1 cm or more greater than the passage of the cutting tool. For example, the length of the aerosol-generating article may be 2 cm or more greater than the passage, 3 cm or more greater than the passage, 10 cm or more greater than the passage, or 20 cm or more greater than the passage.

[0036] The length of the passage in the cutting tool can be greater than the length of the sensor heating element. Alternatively, the length of the passage can be less than the length of the sensor heating element.

[0037] In some preferred embodiments, the cutting tool has a length ranging from 20 mm to 50 mm.

[0038] The body of the cutting tool can have any suitable thickness. In some preferred embodiments, the body of the cutting tool has a thickness ranging from 2 mm to 20 mm, for example from 4 mm to 10 mm.

[0039] The body of the cutting tool can be made of any suitable material or combination of materials. For example, the body of the cutting tool can be made of one or more metals and plastic materials (e.g., hard plastic materials). For example, the body of the cutting tool can be made of polycarbonate, polyetheretherketone, high-density polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, stainless steel, aluminum or aluminum alloys, iron or iron alloys, and combinations thereof. In some embodiments, the body of the cutting tool includes a magnetic material. For example, the body may include a ferromagnetic material, a rare-earth magnetic material, or a combination of ferromagnetic and rare-earth magnetic materials. The entire body may be ferromagnetic, or one or more portions of the body may be ferromagnetic.

[0040] The cutting tool includes a cutting element extending into the passage. The cutting element includes a cutting blade arranged to cut the aerosol-generating article as it passes through the passage. The cutting tool may include any suitable cutting element.

[0041] The cutting element may include a blade, wire, or any other structure having an edge adapted to cut the aerosol-generated article as it passes through the passage. The blade may have a sharpened cutting edge to cut the aerosol-generated article. The blade may be made of any suitable material. For example, the blade may be made of one or more metal and plastic materials (e.g., hard plastic materials). For example, the blade may include one or more of the following: polycarbonate, polyetheretherketone, high-density polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, stainless steel, aluminum or aluminum alloy, iron or iron alloy, titanium or titanium alloy, obsidian, ceramic, etc.

[0042] The blade can extend into the passage a distance sufficient to cut the aerosol-generated article as it passes through the passage. The blade can extend completely across the passage or partially across it. For example, the blade can extend into the passage a distance equal to 20% to 100% of the passage's diameter. In some preferred embodiments, the cutting edge of the blade extends into the passage a distance equal to 30% to 50% of the passage's diameter.

[0043] The wire can be thin enough to cut the aerosol-generating article. Preferably, the wire extends across the passage and is fixed at two locations relative to the passage. The locations where the wire is fixed to the passage can be opposite to the passage or non-opposite to the passage. Fixing the wire at a non-opposite location relative to the passage allows the wire to cut the aerosol-generating article off-center. Off-center cutting of the aerosol-generating article helps ensure that the wire does not cut off or contact the sensor heating element when the aerosol-generating article passes through the passage of the cutting tool.

[0044] Cutting tools may include wires formed from any suitable material. For example, the wire may be made of one or more metals and plastic materials (e.g., hard plastic materials). For instance, the blade may be made of polycarbonate, polyetheretherketone, high-density polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, stainless steel, aluminum or aluminum alloys, iron or iron alloys, titanium or titanium alloys, carbon, ceramics, and combinations thereof. The wire may be in the form of filaments, braided wire, stranded wire, braided stranded wire, etc.

[0045] The cutting element can extend through, towards, or offset from the geometric center of the passage. For example, the cutting edge can be offset from the geometric center of the passage by a distance ranging from 10% to 20% of the passage diameter. Off-center cutting of the aerosol-generating article helps ensure that the cutting element does not cut off or contact the sensor heating element or other parts or components of the aerosol-generating article as it passes through the passage of the cutting tool.

[0046] The cutting element may include one or more cutting blades. For example, the cutting element may include a first cutting blade positioned and arranged to cut the aerosol-generating article as it passes through the passage from a first end to a second end, and the cutting element may include a second cutting blade positioned and arranged to cut the aerosol-generating article as it passes through the passage from a second end to a first end. The first blade may face the first opening. The second end may face the second opening. With this arrangement, the cutting tool can be used to cut the aerosol-generating article regardless of the direction in which the aerosol-generating article passes through the passage.

[0047] The cutting tool may include more than one cutting element. Each cutting element may extend into the passage. Each cutting element may include a cutting blade arranged to cut the aerosol-generating article as it passes through the passage. The cutting elements may be circumferentially spaced around the passage. The cutting elements may be evenly spaced from each other or unevenly spaced from each other.

[0048] The cutting element can be offset longitudinally in the path.

[0049] The cutting element can be offset longitudinally and circumferentially within the passage. This arrangement allows for a second cut to be initiated at a later stage in the aerosol-generated article at a different angle to the article as it passes through the passage.

[0050] The cutting tool may include more than one cutting element, wherein each cutting element includes a blade. The blades may be circumferentially spaced around the passage, wherein each blade extends into the passage. The blades may be evenly spaced from each other or unevenly spaced from each other.

[0051] The blade can be offset longitudinally within the path. The blade can also be offset circumferentially within the path.

[0052] A cutting tool may include more than one cutting element, wherein each cutting element includes wire. A cutting tool may include more than one cutting element, wherein at least one cutting element includes a blade and at least one cutting element includes wire.

[0053] The cutting tool may include a cutting element comprising a magnet configured to magnetically attract a sensor heating element. As the aerosol-generating article passes through the path of the cutting tool, the cutting edge of the cutting element cuts the aerosol-generating article. When the sensor heating element passes near the magnet of the cutting element, the magnet can attract and hold the sensor heating element.

[0054] The cutting element, or a portion thereof, may be insertable into and removable from the passage. When inserted into the passage, the cutting element is arranged to cut the aerosol-generating article as it passes through the passage. When removed from the passage, the cutting element is configured to cause the removal of a magnetically attracted sensor heating element.

[0055] In some preferred embodiments, the cutting element includes a blade and a magnet. For example, the magnet may be positioned on the side of the blade. As the aerosol-generating article passes through the blade, the cutting edge of the blade cuts the aerosol-generating article. As the sensor heating element passes through the cutting edge of the blade, the sensor heating element is magnetically attracted to the magnet positioned on the side of the blade. The blade may include a magnetic material. The blade may include a magnetizable material.

[0056] The body of the cutting tool may include a slot configured to receive a cutting element such that, when the cutting element is received in the slot, a cutting edge is arranged to cut the aerosol-generating article as it passes through the passage. The cutting element may be removable from the slot. If the sensor heating element is magnetically attracted and held by the cutting element after the aerosol-generating article has passed through the passage of the cutting tool, removing the cutting element from the slot may result in the removal of the sensor heating element.

[0057] The cutting tool can be configured such that, prior to removal of the cutting element and multiple magnetically attracted sensor heating elements, the cutting element can magnetically attract sensor heating elements from more than one aerosol-generating article. For example, the cutting tool can be configured such that the cutting element can hold a first sensor heating element from a first aerosol-generating article that has already passed through the passage of the cutting tool, while cutting a second aerosol-generating article and holding a second sensor heating element as a second aerosol-generating article passes through the passage.

[0058] The cutting tool may include more than one cutting element, the cutting element comprising a magnet or a magnetizable material, wherein the cutting element is circumferentially offset. The cutting tool may be oriented such that a first aerosol-generating article passes through the passage such that a sensor heating element from the first aerosol-generating article is attracted to the first cutting element. The cutting tool may then be oriented such that a second aerosol-generating article passes through the passage such that a sensor heating element from the second aerosol-generating article is attracted to the second cutting element.

[0059] When the cutting element comprises a magnetic or magnetizable material and is removable from the cutting tool to induce the removal of a magnetically attracted sensor heating element, the length of the passage may be greater than the length of the sensor heating element that the cutting tool is configured to remove. A passage having a length greater than the sensor heating element can be used to hold the sensor heating element within the passage to prevent accidental contact by a user. Alternatively, the passage may be shorter than the length of the sensor heating element. A passage shorter than the sensor heating element can facilitate the removal of the sensor heating element from the cutting tool without having to remove the cutting element from the cutting tool.

[0060] The cutting element may comprise any suitable magnet or magnetizable material. For example, the cutting element may comprise a ferromagnetic or rare-earth magnet. Preferably, the cutting element comprises a rare-earth magnet. Examples of suitable rare-earth magnets include neodymium magnets and samarium magnets.

[0061] The cutting tool may include an alignment indicator that can be aligned with an indicator on the aerosol-generating article. The indicator on the aerosol-generating article may be positioned relative to the sensor heating element. Alignment of the indicator on the aerosol-generating article with the alignment indicator on the cutting tool orients the aerosol-generating article relative to the cutting element, such that the cutting element avoids the sensor heating element as the aerosol-generating article passes through the path of the cutting tool. Depending on the type of sensor heating element, the cutting element may not be able to cut through it. Therefore, orienting the aerosol-generating article relative to the cutting tool in a manner that avoids contact between the sensor heating element and the cutting element allows the aerosol-generating article to pass freely through the path of the cutting tool. This arrangement can also reduce blade degradation.

[0062] If the cutting element includes a magnet or a magnetizable material, the alignment of the indicator on the aerosol generating article with the alignment indicator of the cutting tool as the aerosol generating article passes through the passage can orient the aerosol generating article relative to the cutting element, such that the magnet or magnetizable material of the cutting element is placed close enough to the sensor heating element that the magnet or magnetizable material attracts and holds the sensor heating element.

[0063] Cutting tools may include any suitable alignment indicator. Indicators may include raised marks, recessed marks, color marks, etc.

[0064] The present invention includes components comprising a cutting tool and a heating element removal tool. The heating element removal tool includes a magnet to attract a receptor heating element. For example, the heating element removal tool may include a tip configured to magnetically attract the receptor heating element. After the aerosol-generating article has been cut and optionally separated, the tip of the heating element removal tool may be placed near the receptor heating element. The magnetic attraction between the tip of the heating element removal tool and the receptor heating element may engage the tip with the receptor heating element to facilitate removal of the receptor heating element from the cut aerosol-generating article.

[0065] The tip of the heating element may comprise any suitable magnetic material. For example, the tip may comprise a ferromagnetic material, a rare-earth magnetic material, or a combination of both. Preferably, the tip comprises a rare-earth magnetic material. Examples of suitable rare-earth magnetic materials include neodymium magnets and samarium magnets.

[0066] The tip of the heating element removal tool can be of any suitable shape. Preferably, the tip is conical. A conical magnet can provide an enhanced magnetic field gradient focused on the tip of the conical portion.

[0067] The tip of the heating element removal tool can be inserted into and removed from the passage of the cutting tool. Therefore, the tip can have a diameter smaller than the diameter of the passage.

[0068] The heating element removal tool can be retainable in a passage. For example, the tip of the heating element removal tool can be inserted into the passage and at least a portion of the heating element removal tool can be retained in the passage. The heating element removal tool can be retained in the passage in any suitable manner. For example, the tip of the heating element removal tool can be magnetically attracted to a cutting element or a portion of the body of the cutting tool. Magnetic attraction can retain the heating element removal tool in the passage until a force sufficient to overcome the magnetic attraction is applied to remove the heating element removal tool or a portion of the heating element removal tool from the passage. Alternatively or additionally, the cutting tool may include a magnet that magnetically attracts a portion of the heating element removal tool. For example, a portion of the body of the cutting tool defining the passage may include a magnet. Alternatively or additionally, the heating element removal tool can be retained in the passage via interference fit, threaded engagement, snap-fit, etc.

[0069] Keeping at least a portion of the heating element removal tool within the passageway of the cutting tool provides more compact storage for both the cutting tool and the heating element removal tool, and prevents separation of the tools, making both tools available to the user when needed.

[0070] A heating element removal tool may be included at one end distal to the magnetic tip. The distal end, or a portion of the heating element removal tool between the distal end and the magnetic tip, preferably has an outer diameter larger than the diameter of the passage of the cutting tool. This portion of the heating element removal tool with a diameter larger than the diameter of the passage preferably abuts the body of the cutting tool near the opening of the passage. Preferably, the external shape and dimensions of the portion of the heating element removal tool abutting the body of the cutting tool near the opening of the passage are the same as or substantially the same as the external shape and dimensions of the body of the cutting tool. This matching shape and dimensions, due to the substantially continuous outer surfaces formed between the two tools, can reduce the likelihood of accidental separation of the heating element removal tool and the cutting tool.

[0071] The assembly, including the heating element removal tool and the cutting tool, may also include a separator tool. The separator tool can be configured to assist in separating a portion of the cut aerosol-generating article from the opposite portion of the cut aerosol-generating article along the cut. Separation of the opposite portion of the aerosol-generating article provides better access to the sensor heating element, which facilitates the removal of the sensor heating element using the heating element removal tool.

[0072] A separator tool may include an expander. A separator tool may include a first arm having a free end and a second arm having a free end. The tool may be configured such that an inward force, such as a compressive force, applied to the middle section of the first and second arms causes the free ends of the first and second arms to separate. For example, a separator tool may include a splitter.

[0073] The separator tool, or a portion thereof, is preferably insertable into and removable from the passage of the cutting tool. The separator tool may be retainable within the passage. For example, an end of the separator tool may be inserted into the passage, and at least a portion of the separator tool may be retained within the passage. The separator tool may be retained in the passage in any suitable manner. For example, an end of the separator tool configured to be inserted into the passage of the cutting tool may be magnetically attracted to the cutting element or a portion of the body of the cutting tool. Magnetic attraction may retain the separator tool in the passage until a force sufficient to overcome the magnetic attraction is applied to remove the separator tool or a portion thereof from the passage. Alternatively or additionally, the cutting tool may include a magnet that magnetically attracts a portion of the separator tool. For example, a portion of the body of the cutting tool defining the passage may include a magnet. Alternatively or additionally, the separator tool may be retained in the passage via an interference fit, threaded engagement, snap-fit, or the like.

[0074] Keeping at least a portion of the separator tool within the path of the cutting tool provides compact storage for both the cutting and separator tools and prevents tool separation, ensuring that both tools are available to the user when needed.

[0075] A separator tool may include an end portion distal to the end configured to be inserted into a passage. The distal end, or a portion of the separator tool between the distal end and the end configured for insertion into the passage, preferably has an outer diameter larger than the diameter of the passage of the cutting tool. The portion of the separator tool having a diameter larger than the diameter of the passage preferably abuts the body of the cutting tool near the opening of the passage. Preferably, the external shape and dimensions of the portion of the separator tool abutting the body of the cutting tool near the opening of the passage are the same as or substantially the same as the external shape and dimensions of the body of the cutting tool. This matching shape and dimensions provide a smooth appearance and reduce the likelihood of accidental separation of the separator tool and the cutting tool due to the substantially continuous outer surfaces formed between the two tools.

[0076] In some preferred embodiments, the separator tool is configured to be inserted into the passage through a first opening defined by the body of the cutting tool, and the heating element removal tool is configured to be inserted into the passage through a second opening defined by the body of the cutting tool. Preferably, the separator tool and the heating element removal tool can be retained within the passage.

[0150] Figure 10 This is a flowchart illustrating an embodiment of the method according to the present invention. Detailed Implementation

[0151] Figure 1 An example of an aerosol generating article 10 is shown, which can be used in conjunction with the tools, components, uses, and methods of the present invention. The shown aerosol generating article 10 includes four elements arranged coaxially: an aerosol forming matrix 20, a support element 30, an aerosol cooling element 40, and a mouthpiece 50. Each of these four elements is a substantially cylindrical element, each having substantially the same diameter. These four elements are arranged sequentially and surrounded by an outer casing 60 to form a cylindrical strip. A blade-shaped sensor heating element 25 is located within the aerosol forming matrix 20 and is in direct physical contact with the aerosol forming matrix. The sensor heating element 25 has a length substantially the same as the length of the aerosol forming matrix 20 and is positioned along the longitudinal axis of the aerosol generating article 10.

[0152] The sensor heating element 25 is made of ferritic iron material, with a length of 12 mm, a width of 4 mm, and a thickness of 1 mm. The end of the sensor heating element 25 is pointed to facilitate insertion into the aerosol forming matrix 20.

[0153] The aerosol generating article 10 has a proximal or oral end 70 that the user inserts into his or her mouth during use, and a distal end 80 located at the end of the aerosol generating article 10 opposite to the oral end 70. Once assembled, the aerosol generating article 10 has a total length of approximately 45 mm and a diameter of approximately 7.2 mm.

[0154] exist Figure 2 A schematic cross-sectional view of an electrically operated aerosol generating apparatus 200 is shown. The aerosol generating apparatus 200 includes a sensor 210 located near the distal portion 231 of a matrix receiving cavity 230. In use, the user inserts the aerosol generating article 10 into the matrix receiving cavity 230 of the aerosol generating apparatus 200, such that the aerosol forming matrix 20 of the aerosol generating article 10 and the sensor heating element 25 are located near the sensor 210.

[0155] The aerosol generating device 200 includes a battery 250 and electronics 260 that allow the sensor 210 to be actuated. This actuation can be manual or can be automatic in response to a user drawing aerosol-generating article 10 inserted into the matrix receiving chamber 230 of the aerosol generating device 200.

[0156] When actuated, high-frequency alternating current passes through a coil of wire forming part of the sensor 210, causing the sensor 210 to generate a undulating electromagnetic field within the distal portion 231 of the matrix receiving cavity 230. When the aerosol-generating article 10 is correctly positioned within the matrix receiving cavity 230, the sensor heating element 25 of the article 10 is located within this undulating electromagnetic field. The undulating field generates eddy currents within the sensor material of the sensor heating element 25, thus heating the sensor heating element. The heated sensor heating element heats the aerosol-forming matrix 20 of the aerosol-generating article 10 to a temperature sufficient for aerosol formation. The aerosol is drawn downstream through the aerosol-generating article 10 and inhaled by the user. Figure 3 An aerosol-generated article 10 is shown being received in cavity 230 of aerosol-generating apparatus 200.

[0157] Figure 4 An aerosol-generating article 10 and a cutting tool 400 are shown. The cutting tool 400 has a body 410 that defines a passage 420 extending the length of the cutting tool 400. The cutting tool 400 includes a blade 430 that extends from the body 410 into the passage 420. The depicted cutting tool 400 includes two cutting edges. One cutting edge faces... Figure 4 The opening on the right side is defined by the main body 410, and another cutting edge faces the... Figure 4 The opening on the left side is defined by the main body 410.

[0158] The aerosol-generating article 10 can pass through the passage 420 of the cutting tool 400 from right to left. However, because the blade 430 has opposing cutting edges, the aerosol-generating article 10 can also pass through the passage 420 from left to right. The diameter of the passage 420 is larger than the outer diameter of the aerosol-generating article 10 to allow the aerosol-generating article 10 to pass through the passage 420. The diameter of the passage 420 can be 8 mm, and the diameter of the aerosol-generating article 10 can be 7.2 mm.

[0159] After passing through the cutting tool 400, the aerosol-generated article 10 is cut.

[0160] Figure 5 A cut aerosol generating article 10 is shown, the cut having been made along line 15 to expose internal components including a receptor heating element 25. The receptor heating element 25 can be removed from the aerosol generating article 10 using a heating element removal tool 700 with a magnetic tip 710. When the magnetic tip 710 is placed near the receptor heating element 25, the receptor heating element 25 is attracted to the tip 710 and can be removed from the aerosol generating article 10, as shown. Figure 6 As shown in the image.

[0161] Alternatively, cut the element (e.g., as...) Figure 4 The blade 430 shown may include a magnet that attracts a sensor heating element as the aerosol-generating article passes through the passage of the cutting tool, and the cutting element and the attracted sensor heating element can be removed from the cutting tool to retrieve the sensor heating element (not shown).

[0162] Figure 7 A heating element removal tool 700 is shown, which is inserted into the passage 420 of a cutting tool 400 for storage. The tip 710 of the heating element removal tool 700 is magnetic and attracted to the blade 430, whose magnetic attraction holds the heating element removal tool 700 within the passage of the cutting tool 400. The heating element removal tool 700 includes a shaft 720 extending from a distal handle portion 730 to the magnetic tip 710. The diameter of the distal handle portion 730 is larger than the diameter of the passage 420 but substantially the same as the outer diameter of the body 410 of the cutting tool 400, thereby providing a smooth transition between the outer surfaces of the cutting tool 400 and the heating element removal tool 700 when the heating element removal tool 700 is stored in the passage 420 of the cutting tool 400.

[0163] like Figure 8 As shown, the separator tool 900 can also be inserted into and held within the passage 420 of the cutting tool 400. The tip of the separator tool 900 can be magnetic and attracted to the blade 430, or it can be magnetically attracted to the tip 710 of the heating element removal tool 700. Magnetic attraction holds the separator tool 900 within the passage of the cutting tool 400. The separator tool 900 includes a shaft 920 extending from a distal handle portion 930 to the tip. The diameter of the distal handle portion 930 is larger than the diameter of the passage 420 but substantially the same as the outer diameter of the body 410 of the cutting tool 400, thereby providing a smooth transition between the outer surfaces of the cutting tool 400 and the separator tool 900 when the separator removal tool 900 is stored in the passage 420 of the cutting tool 400.

[0164] A schematic diagram of an example of the separator tool 900 is shown in Figure 9 The separator tool 900 is shown in the diagram. It includes a handle 930 and a first arm 941 and a second arm 942 extending from the handle 930. An inward pressing force on the middle sections of arms 941 and 942 causes the free ends of arms 941 and 942 to separate. The free ends of arms 941 and 942 act as expanders. The free ends of arms 941 and 942 of the separator tool 900 are inserted into a cut in the aerosol-generating article (e.g., ...). Figure 5The cut 15 depicted in the figure and the middle section of the extrusion arms 941, 942 separate the free end of the separator tool 900, which causes the opposing surfaces of the aerosol-generated article to separate along the cut. Separating the opposing surfaces of the aerosol-generated article along the cut provides access to the sensor heating element, which can be removed from the aerosol-generated article using a heating element removal tool.

[0165] Figure 10 This is a flowchart illustrating an example of a method according to the invention. The method includes passing an aerosol-generating article through a passage of a cutting tool to cut the aerosol-generating article (121). The method also includes removing a sensor heating element (123) from the cut aerosol-generating article.
