Description

Aerosol-generating article and method of producing the same

The present disclosure relates generally to aerosol-generating articles, and more specifically to aerosol-generating articles for use with an aerosol-generating device for heating the aerosol-generating article to generate an aerosol to be inhaled by a user. Embodiments of the present disclosure also relate to methods for making aerosol-generating articles. The present disclosure may particularly apply to aerosol generating articles for use with hand-held aerosol generating devices.

The popularity and use of reduced or improved risk devices (also known as aerosol-generating devices or vapor-generating devices) have grown rapidly in recent years as an alternative to the use of traditional tobacco products. A variety of devices and systems are available that heat or warm an aerosol-generating material to generate an aerosol that can be inhaled by a user.

Commonly available reduced or improved risk devices are substrate-heated aerosol generating devices or so-called heat-not-burn devices. Devices of this type produce aerosols or vapors by heating an aerosol-generating substrate to a temperature typically in the range of 150°C to 300°C. Heating the aerosol-generating substrate to a temperature within this range, with or without burning, typically generates a vapor that cools and condenses to form an aerosol that can be inhaled by the user of the device.

Currently available aerosol generating devices utilize one of several different approaches, including resistive heating using resistive heating elements, and induction heating using heating elements in the form of induction coils and inductively heated susceptors. may provide heat to the aerosol-generating substrate.

Regardless of the approach used to heat the aerosol-generating substrate, the properties of the aerosol produced by the aerosol-generating device depend on several factors, including the composition of the aerosol-generating article used with the aerosol-generating device. Accordingly, it is desired to provide an aerosol-generating article that is capable of optimizing the properties of the aerosol generated during use of the aerosol-generating article and, at the same time, is easy to use in combination with an aerosol-generating device.

According to a first aspect of the present disclosure, there is provided an aerosol-generating article for use with an aerosol-generating device, the aerosol-generating article comprising:

a substantially planar aerosol-generating substrate;

A wrapping member surrounding a substantially planar aerosol-generating substrate to form a substantially planar aerosol-generating article.

Including,

The wrapping member includes a window that is aligned with a portion of the aerosol generating substrate.

According to a second aspect of the present disclosure, a method of making an aerosol-generating article for use with an aerosol-generating device is provided, the method comprising:

providing a substantially planar aerosol-generating substrate;

providing a wrapping member containing a window;

wrapping the substantially planar aerosol-generating substrate with a wrapping member to form a substantially planar aerosol-generating article; and

Aligning the window within the wrapping member with a portion of the aerosol generating substrate.

Includes.

The wrapping and aligning steps can be performed in any order. For example, the method may include first aligning a window in the wrapping member with a portion of the aerosol-generating substrate, and second aligning the substantially planar aerosol-generating substrate with the wrapping member to form a substantially planar aerosol-generating article. It may include a wrapping step, or vice versa.

The aerosol-generating article is provided without combusting the aerosol-generating substrate to volatilize at least one component of the aerosol-generating substrate and thereby produce a heated vapor that cools and condenses to form an aerosol for inhalation by a user of the aerosol-generating device. , used in conjunction with an aerosol-generating device to heat an aerosol-generating substrate. The aerosol generating device is a handheld, portable device.

In general terms, a vapor is a substance in the gaseous phase at a temperature below its critical temperature, meaning that the vapor can be condensed into a liquid by increasing its pressure without decreasing its temperature, while an aerosol is an air or It is a suspension of fine solid particles or liquid droplets in another gas. However, it should be noted that the terms 'aerosol' and 'vapour' may be used interchangeably herein, particularly with regard to the form of inhalable medium that is produced for inhalation by a user.

By providing a window in the wrapping member that is aligned with a portion of the aerosol-generating substrate, heat transfer from the heater of the aerosol-generating device to the aerosol-generating substrate can be improved, thereby allowing the aerosol-generating substrate to heat more efficiently and more quickly. there is. For example, a window may allow the aerosol-generating substrate to be in direct contact with the heater of the aerosol-generating device. This ensures that vapors can be generated more easily and can help improve the energy efficiency of aerosol generating devices.

The wrapping member may include a sheet material, and the window may include a die-cut portion formed in the sheet material. The windows can be easily formed in the sheet material, for example by a die-cutting operation, and can be easily aligned with portions of the aerosol-generating substrate during manufacture of the aerosol-generating article.

The aerosol-generating substrate may include a major surface. The window may be disposed adjacent to the major surface, may lie over a portion of the major surface (i.e., may lie flat relative to it), and may have an area that is less than the area of the major surface. This ensures that the aerosol-generating substrate cannot pass through the window and that the aerosol-generating substrate is securely held in place within the wrapping member.

The wrapping member may extend beyond the end of the aerosol-generating substrate to form a rostral end portion of the article. The extended portion of the wrapping member allows heated vapors generated during use of the aerosol-generating article to cool and condense to form an aerosol with optimal properties for inhalation by a user.

The wrapping member may include a removable portion that can cover the window. The wrapping member may include one or more lines of weakness forming a perimeter of the removable portion. The detachable portion may be detached by the user prior to use of the aerosol-generating article within the aerosol-generating device. The removable portion helps protect the aerosol-generating substrate prior to use of the aerosol-generating article and can help secure the aerosol-generating substrate in place within the wrapping member. The detachable portion can be easily removed by the user prior to use of the aerosol-generating article, thereby allowing direct contact between, for example, the aerosol-generating substrate and the heater of the aerosol-generating device.

One or more lines of weakness may include one or more perforations. Accordingly, the detachable part can be easily detached and discarded, for example by rupturing.

A substantially planar aerosol-generating substrate may be of a flat rectangular shape, which may have a pair of major surfaces. The wrapping member may include a pair of rectangular sheets that can each be attached to a pair of major surfaces. The aerosol-generating article can have a pleasing aesthetic appearance due to the flat, rectangular shape of the aerosol-generating substrate. A significant portion of the aerosol-generating substrate can easily be covered by the wrapping member, thereby ensuring that the user does not come into direct contact with the aerosol-generating substrate during handling of the aerosol-generating article. The flat, rectangular shape can also aid in packaging and storage of many aerosol-generating items.

The aerosol-generating article may include a support member that may form a rostral end portion of the article. The support member may have a tube shape, for example a rectangular tube shape, to receive the downstream end of the aerosol generating substrate. The support member may be self-supporting and may be made of cardboard or plastic material, for example. The support member can advantageously deliver vapors and/or aerosols generated during use of the article directly to the user's mouth. The support member allows heated vapors generated during use of the aerosol-generating article to cool and condense to form an aerosol with optimal properties for inhalation by a user.

The wrapping member may comprise a substantially non-electrically conductive and non-magnetic permeable material and may include, for example, a paper wrapper. The use of paper wrappers can facilitate the manufacture and handling of aerosol-generating articles and can enhance aerosol generation.

The wrapping member can have a porous interior surface that can face toward the aerosol-generating substrate to absorb condensate. The porous interior surface can help ensure that condensation is substantially prevented or at least minimized from forming on the interior surface of the aerosol generating device. The wrapping member can have an anti-stick outer surface that can face away from the aerosol generating substrate. For example, the wrapping member may include an anti-stick coating on the exterior surface. The anti-stick outer surface can help ensure that the wrapping member does not stick to the surface of the aerosol generating device when heated. Both a porous internal surface and an anti-stick external surface can help reduce residue build-up within the aerosol generating device, thereby reducing the number of cleaning and maintenance tasks that must be performed by users of the device.

The aerosol generating substrate may be made of non-liquid aerosol generating material, for example any type of solid or semi-solid material. Exemplary types of aerosol-generating solids include powders, granules, pellets, flakes, strands, particles, gels, strips, loose leaves, cut leaves, cut fillers, porous materials, foam materials or sheets. Aerosol-generating substrates may include plant-derived materials, particularly tobacco. Advantageously, it may comprise, for example, tobacco and reconstituted tobacco comprising any one or more of cellulose fibers, tobacco stem fibers, and inorganic fillers such as CaCO3.

As a result, aerosol-generating devices intended for use with aerosol-generating articles may be referred to as “heated tobacco devices,” “non-combustible heated tobacco devices,” “devices for vaporizing tobacco products,” etc., which achieve this effect. It is interpreted as a device suitable for the following. The features disclosed herein are equally applicable to devices designed to vaporize any aerosol-generating substrate.

The aerosol-generating substrate may include an aerosol former. Examples of aerosol formers include polyhydric alcohols and mixtures thereof such as glycerin or propylene glycol. Generally, the aerosol-generating substrate may include an aerosol former in an amount of about 5% to about 50% by dry weight. In some embodiments, the aerosol-generating substrate may include an aerosol former in an amount of about 10% to about 20%, and possibly about 15%, based on dry weight.

The aerosol generating article may be configured for use with an electrically-operated aerosol generating device that includes a heater. The heater may be a resistance heater or an induction heater. Upon heating, aerosol-generating substrates can release volatile compounds. Volatile compounds may include flavor compounds such as nicotine or tobacco flavoring.

DETAILED DESCRIPTION Embodiments of the present disclosure will now be described by way of example only with reference to the accompanying drawings.

Referring first to FIGS. 1 and 2 , a first embodiment of an aerosol generating article 1 for use with an electrically-operated aerosol generating device 102 is shown, an example of which is shown with reference to FIG. 6 . This will be described later in the specification. The aerosol-generating article 1 is substantially planar and has a distal end 10 and a rostral end 12 (or proximal ends) at opposing ends of the aerosol-generating article 1 . The rostral end 12 is located downstream of the distal end 10 with respect to the direction of air flow through the aerosol-generating article 1, as indicated by the three arrows in Figure 1. A longitudinal axis extends between the distal end 10 and the rostral end 12 to define the longitudinal direction of the aerosol-generating article 1.

The aerosol-generating article (1) includes a substantially planar aerosol-generating substrate (14). The aerosol-generating substrate 14 may include a bulk or mass of aerosol-generating material or a plurality of aerosol-generating strips, and may be a flat shape having a pair of opposedly disposed major surfaces 14a, 14b. It has a rectangular shape. The aerosol-generating article 1 is a consumable or disposable article, and the aerosol-generating substrate 14 may include tobacco or tobacco material.

The aerosol-generating article 1 includes a wrapping member 22 surrounding a substantially planar aerosol-generating substrate 14 to form the substantially planar aerosol-generating article 1 . Wrapping member 22 may comprise, for example, cigarette paper or similar material. Wrapping member 22 includes a pair of rectangular sheets 24, 26 attached to major surfaces 14a, 14b, respectively, of aerosol-generating substrate 14. The rectangular sheets 24, 26 are generally wrapped around the aerosol-generating substrate 14 and attached to each other within the sealing area 20 (see (c) of FIG. 4) to form the wrapping member 22 into the aerosol-generating substrate ( 14) Formed by a single sheet of material, which may have overlapping edges that secure it in place around it.

In an exemplary, non-limiting embodiment, the aerosol-generating substrate 14 can have a length (in the longitudinal direction of the aerosol-generating article 1) of about 18.0 mm, a width of about 11.8 mm, and a width of about 1.2 mm. It may have a thickness (or depth) of mm. The aerosol-generating substrate 14 may be spaced inwardly from the distal end 10 of the aerosol-generating article 1 by a short distance, for example about 3.0 mm, as shown in FIG. 1 . The aerosol-generating article 1 may have a width of about 12.0 mm and a thickness (or depth) of about 1.4 mm to accommodate the aerosol-generating substrate 14 within the wrapping member 22. An aerosol-generating article (1) can be formed between a distal end (10) and a rostral end (12) by varying the length of the portion of the wrapping member (22) that extends between the downstream end and the rostral end (12) of the aerosol-generating substrate (14). It can have any suitable length in between. The portion of wrapping member 22 that extends beyond the downstream end of aerosol-generating substrate 14 may form a rostral end portion 34 of aerosol-generating article 1 . As the vapor flows through this extended portion of the wrapping member 22 during use of the aerosol generating article 1 within the aerosol generating device 102, the vapor cools and condenses to form an aerosol for inhalation by the user. can do. Accordingly, the length of the portion of wrapping member 22 that extends beyond the downstream end of aerosol-generating substrate 14 can be selected at the time of manufacture to provide an aerosol with desired properties.

In some embodiments, wrapping member 22 includes a porous interior surface 22a that faces toward aerosol-generating substrate 14 and is capable of absorbing condensation that may form during heat treatment. Alternatively or additionally, the wrapping member 22 may face away from the aerosol generating substrate 14 to reduce the risk that the wrapping member 22 may stick to the surface of the aerosol generating device 102 when heated. It may include an anti-stick outer surface 22b. The anti-stick outer surface 22b may include an anti-stick coating on the outer surface 22b of the wrapping member 22.

Wrapping member 22 includes a window 16 that is aligned with a portion of aerosol generating substrate 14. In the first embodiment of the aerosol generating article 1 shown in FIGS. 1 and 2, the window 16 is a die-cut portion 18 formed within the wrapping member 22, for example within a rectangular sheet 24. Includes. The die-cut portion 18 provides a window 16 that opens during manufacturing. Window 16 is disposed adjacent to (i.e., over) major surface 14a of aerosol-generating substrate 14 and exposes major surface 14a. The area of the window 16 is smaller than the area of the major surface 14a of the aerosol-generating substrate 14 and thus overlies a portion of the major surface 14a. Accordingly, the aerosol-generating substrate 14 cannot pass through the window 16 and is securely held in place by the wrapping member 22.

Referring now to Figure 3, a second embodiment of an aerosol-generating article 2 is shown. The aerosol-generating article 2 is similar to the aerosol-generating article 1 described above with reference to FIGS. 1 and 2 and corresponding features are identified using the same reference numerals.

The aerosol-generating article 2 is positioned at the rostral end of the aerosol-generating article 3 to form a rostral end portion 34 that may be in contact with a user's lips during use of the aerosol-generating article 2 within the aerosol-generating device 102. It includes a support member (28) disposed at the end (12). The support member 28 generally comprises a self-supporting material, such as a cardboard or plastic material, and has the shape of a rectangular tube in cross-section to accommodate the downstream end of the aerosol-generating substrate 14. Wrapping member 22 also surrounds support member 28.

Referring now to Figures 4(a) to 4(d), an example of a method for manufacturing the first embodiment of the aerosol-generating article 1 described above with reference to Figures 1 and 2 is shown. . In the first step, shown in Figure 4(a), the method includes providing a substantially planar aerosol generating substrate 14 and forming windows 16 in the form of die-cut portions 18 as described above. and providing a wrapping member (22) comprising: The aerosol-generating substrate 14 and wrapping member 22 are then positioned relative to each other such that the window 16 is aligned with a portion of the aerosol-generating substrate 14, as shown in Figure 4(b). As mentioned above, the area of the window 16 is less than the area of the major surfaces 14a, 14b of the aerosol-generating substrate 14, thereby preventing the aerosol-generating substrate 14 from passing through the window 16. . The wrapping member 22 then ensures that the window 16 is continuously aligned with the aerosol-generating substrate 14 to form a substantially planar aerosol-generating article 1, as shown in Figure 4(c). It is wrapped around the aerosol generating substrate 14 as shown. The overlapping edges of the wrapping members 22 are attached to each other within the sealing area 20 as shown in Figure 4(c), thereby securing the wrapping members 22 in place about the aerosol generating substrate 14. It can be done as much as possible. Figure 4(d) is a schematic view (similar to Figure 1) of the final aerosol-generating article 1 from the side opposite to the side shown in Figure 4(c).

Referring now to Figures 5(a)-5(d), an example of a method for making a third embodiment of the aerosol-generating article 3, best shown in Figure 5(d), is shown. there is. In the first step shown in Figure 5(a), the method includes providing a substantially planar aerosol generating substrate 14, and providing a wrapping member 22 comprising windows 16. do. In this embodiment, wrapping member 22 includes a removable portion 30 that covers window 16. The periphery of the detachable part 30 is defined by a line of weakness 32 in the form of a perforation 36 . The aerosol generating substrate 14 and the wrapping member 22 (having a detachable portion 30) are then connected to a window 16 (more specifically the detachable portion 30) as shown in Figure 5(b). ) are positioned relative to each other so that they are aligned with a portion of the aerosol generating substrate 14. As mentioned above, the area of window 16 (more specifically, removable portion 30) is less than the area of major surfaces 14a, 14b of aerosol-generating substrate 14, and thus window 16 It is positioned over a portion of the major surfaces 14a, 14b to prevent the aerosol generating substrate 14 from passing through the window 16 after removal of the removable portion 30. The wrapping member 22 then allows the window 16 (more specifically the detachable portion 30) to be continuously aligned with the aerosol-generating substrate 14 to form a substantially planar aerosol-generating article 3. while ensuring that it is wrapped around the aerosol generating substrate 14 as shown in Figure 5(c). The overlapping edges of the wrapping members 22 are attached to each other within the sealing area 20 as shown in Figure 5(c), thereby securing the wrapping members 22 in place about the aerosol generating substrate 14. It can be done as much as possible. Figure 5(d) shows the final aerosol-generating article 3 from the side opposite the side shown in Figure 5(c), with the detachable portion 30 intact. Prior to using the aerosol generating article 3 within the aerosol generating device 102, the removable portion 30 is removed by the user to form a window 16 thereby forming the aerosol generating substrate underneath the window 16 ( Part of 14) is exposed. Perforations 36 or similar lines of weakness 32 allow a user to easily remove the removable portion 30 while leaving the remainder of the wrapping member 22 intact.

Referring now to Figure 6, an aerosol generating system 100 is shown comprising a first embodiment of an aerosol generating device 102 and an aerosol generating article 1 as described above with reference to Figures 1 and 2. . The present disclosure, wherein the aerosol generating device 102 is the same as the second and third embodiments of the aerosol generating articles 2 and 3 described above with reference to FIGS. 3 and 5 (a) to 5 (d). It will be appreciated that it may be used in combination with alternative aerosol generating articles depending on the context.

The aerosol generating device 102 includes a receiving chamber 106 and a heater 104 disposed within the device body 108 to provide heat to the receiving chamber 106. Heater 104 may be a resistive heater, or alternatively may be an inductive heater comprising an electromagnetic field generator comprising a susceptor and an induction coil.

In use, the user inserts the aerosol-generating article 1 into the receiving chamber 106 with the window 16 facing toward the heater 104. Aerosol generating device 102 may include a cover 110 and a pivot mount 112 that allows cover 110 to be moved between a closed position shown in FIG. 6 and an open position (not shown). As will be appreciated by those skilled in the art, the user must pivot the cover 110 to an open position allowing insertion of the aerosol generating article 1 into the receiving chamber 106 and then place the cover back into the closed position shown in FIG. 6 . The aerosol-generating article 1 must be pivoted into position to maintain it in place within the receiving chamber 106.

The aerosol generating device 102 includes a power source 114, such as a rechargeable battery, and a controller 116, all of which are connected to a heater 104. Heater 104 may be activated manually, for example via a user interface, such as a button on aerosol generating device 102, or in response to a user sucking on mouthpiece 118 of aerosol generating device 102. It can operate automatically. The aerosol generating device 102 includes one or more air inlets 120 that allow air to flow into the aerosol generating article 1 and through the aerosol generating substrate 14. The air flow direction is shown by arrows in Figure 6.

Once the aerosol-generating article 1 is placed within the receiving chamber 106, power is supplied from the power source 114 to the heater 104 (by manual or automatic operation of the heater 104 as described above), and thus Non-combustible heating of the aerosol-generating substrate 14 releases one or more volatile components. The windows 16 within the wrapping member 22 allow heat to be transferred directly from the heater 104 to the aerosol-generating substrate 14 and, although not apparent in Figure 6, the surface of the aerosol-generating substrate 14 is exposed to the heater ( 104) can be contacted directly. Volatile components released by the heated aerosol-generating substrate 14 become entrained in the air flowing through the aerosol-generating substrate 14, thereby forming vapor. As the vapor flows through the aerosol-generating article 1, it cools and condenses, thereby forming an aerosol that is inhaled by the user through the mouthpiece 118 of the aerosol-generating device 102.

When the aerosol-generating substrate 14 is exhausted and no longer releases sufficient volatile components to generate an aerosol of acceptable quality, the cover 110 is pivoted to an open position and the aerosol-generating article 1 is placed in the receiving chamber ( 106) and a replacement aerosol-generating article 1 can be inserted in its place.

When the aerosol-generating device 102 is used with an aerosol-generating article having a support member 28, for example the second embodiment of the aerosol-generating article 2 described above with reference to FIG. 3, the support member 28 ) may protrude from the open end 106a of the receiving chamber 106, such that the user's lips may contact the rostral end portion 34 of the aerosol-generating article 2 defined by the support member 28. there is.

The aerosol generating device 102 is configured such that the wrapping member 22 is detachable, for example, as in the third embodiment of the aerosol generating article 3 described above with reference to FIGS. 5 (a) to 5 (d). When used with an aerosol-generating article having a detachable portion 30, prior to placing the aerosol-generating article 3 within the receiving chamber 106, the user must detach, e.g., tear off, the detachable portion 30. do.

Although example embodiments have been described in the preceding paragraphs, it should be understood that various modifications may be made to these embodiments without departing from the scope of the appended claims. Accordingly, the scope and scope of the claims should not be limited by the exemplary embodiments described above.

Any combination of the above-described features in all possible variations is encompassed by the present disclosure unless otherwise indicated herein or otherwise clearly contradicted by context.

Unless the context clearly requires otherwise, throughout the description and claims of the present invention, the terms "comprise", "comprising", etc. are used in an inclusive rather than exclusive or limiting sense, i.e., "including but limited to" It should be interpreted as meaning “it doesn’t work.”
