Description

The present disclosure relates generally to aerosol product articles, and more specifically to aerosol product articles for use in an aerosol generating device that heats the aerosol product article to generate an aerosol for inhalation by a user. The present disclosure is particularly applicable to aerosol product articles for use in portable (handheld) aerosol generating devices.

Risk reduction or risk modification devices (also known as aerosol generating devices or vapour generating devices) have grown rapidly in popularity and use 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 for inhalation by the user.

Commonly available risk reduction or risk modification devices are heated substrate aerosol generation devices or so-called heated non-flammable devices. This type of device produces an aerosol or vapor by heating an aerosol-generating substrate to a temperature typically in the range of 150°C to 300°C. The vapor produced by heating the aerosol-generating substrate to a temperature within this range without combusting the aerosol-generating substrate is typically cooled and condensed to form an aerosol for inhalation by the user of the device. form.

Currently available aerosol generation devices are one of many different approaches to providing heat to an aerosol generation substrate, including resistive heating, which utilizes a resistive heating element, and induction heating, which utilizes an induction coil and an inductively heatable susceptor. One can be used.

Regardless of the approach used to heat the aerosol-generating substrate, the properties of the aerosol produced by the aerosol-generating device depend on many factors, including the construction of the aerosol-generating article used in the aerosol-generating device. It is therefore desirable to provide an aerosol-generating article that makes it possible to optimize the properties of the aerosol produced during use of the article, while at the same time being easy to use in combination with an aerosol-generating device.

According to a first aspect of the present disclosure, an aerosol-generating article for use in an aerosol-generating device is provided, the aerosol-generating article comprising:
a substantially flat aerosol-generating substrate;
at least one airflow channel extending along a substantially flat aerosol-generating substrate;
It includes a substantially flat aerosol-generating substrate and a wrapping member surrounding at least one airflow channel.

The aerosol-generating article generates an aerosol for inhalation by a user of the aerosol-generating device by heating the aerosol-generating substrate to volatilize at least one component of the aerosol-generating substrate without burning the aerosol-generating substrate. It is intended for use in aerosol generation devices that produce heated steam that is cooled and condensed to form. The aerosol generation device is a hand-held portable device.

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

By surrounding the at least one air flow channel with a packaging member, the vapor and/or aerosol generated during use of the aerosol product article in the aerosol generating device flows inside the article along the at least one air flow channel before being inhaled by the user. This may provide a number of advantages since the formation of condensation material on the inner surface of the aerosol generating device is substantially eliminated or at least minimized. For example, it may help to reduce the build-up of residues in the aerosol generating device and thus reduce the number of cleaning and maintenance tasks that the user of the device must perform. It may also help to ensure that the maximum amount of vapor and/or aerosol possible is delivered to the user and that the delivered vapor and/or aerosol has optimal properties.

The aerosol product article may include a distal end, a mouth end, and a longitudinal axis that may extend between the mouth end and the distal end. The mouth end is located at an end of the aerosol product article opposite the distal end. More specifically, the mouth end is located downstream of the distal end with respect to an airflow direction through the aerosol product article during use of the aerosol product article, for example, in an aerosol generating device. The at least one airflow channel may extend in a first direction that may be substantially parallel to the longitudinal axis. Because air flows along the at least one airflow channel from the distal end to the mouth end during use of the aerosol product article, it is ensured that a maximum amount of volatile components is released from the heated aerosol generating substrate into the air as the air flows along the airflow channel. This, in turn, ensures that a maximum amount of vapor and/or aerosol possible is generated and delivered to a user during use of the aerosol product article.

The at least one airflow channel may include at least one groove. At least one groove may be formed in the surface of the substantially flat aerosol-generating substrate. The at least one groove can be readily formed during manufacture of the aerosol-generating article, for example, by pressing the surface of a substantially flat aerosol-generating substrate.

The aerosol generating substrate may include a plurality of the grooves. These grooves may, for example, be arranged side by side to form a grooved surface. By providing multiple grooves, increased amounts of vapor and/or aerosol can be generated and delivered to a user during use of the aerosol-generating article in an aerosol-generating device.

The at least one airflow channel may include at least one air flow passage formed internally within the aerosol-generating substrate. The air flow passage may be readily formed during manufacture of the aerosol product article. Because the air flow passage is completely surrounded by the aerosol-generating substrate, a maximum amount of volatile components may also be released into the air from the heated aerosol-generating substrate as air flows along the air flow passage, thereby ensuring that a maximum amount of vapor and/or aerosol possible is generated and delivered to a user during use of the aerosol product article in the aerosol generating device.

In one example, a single air flow passage may be formed internally within the aerosol-generating substrate, for example at a substantially central location within a cross-section of the aerosol-generating substrate. In another example, multiple air flow passages may be formed internally within the aerosol-generating substrate, for example arranged side-by-side in a second direction perpendicular to the first direction (longitudinal direction). By providing multiple air flow passages, increased amounts of vapor and/or aerosol may be generated and delivered to a user during use of the aerosol product article in the aerosol generating device.

The aerosol-generating substrate can include a plurality of aerosol-generating strips. The aerosol-generating strip may, for example, extend in a first direction substantially parallel to the longitudinal axis and may be disposed intermittently in a second direction, which may be substantially perpendicular to the first direction. The aerosol-generating article may include a plurality of the air flow channels, and one of the air flow channels may be formed between each pair of intermittently disposed aerosol-generating strips. Each airflow channel is in fluid communication with a pair of intermittent aerosol generating strips forming a particular airflow channel. The vapor or aerosol generated during the heating of the aerosol generation strip therefore flows into the adjacent airflow channel, and the generated vapor or aerosol is entrained by the air flowing through the airflow channel to form the aerosol in the aerosol generation device. When the product is heated during use, it is ensured that it can be delivered to the user during inhalation. The aerosol generating strip has at least one side extending in a first direction that is directly exposed to and in fluid communication with an adjacent airflow channel. This arrangement allows a large surface area of each aerosol-generating strip to be directly exposed to at least one adjacent airflow channel, thereby increasing the delivery of vapor or aerosol through the airflow channel for inhalation by the user. I can do it. Additionally, with this arrangement, airflow channels can be easily formed during manufacture of the aerosol-generating article, for example, by spacing the aerosol-generating strips apart in the second direction to form the airflow channels. Aerosol-generating articles can therefore be efficiently manufactured and relatively easily mass-produced.

The aerosol-generating strips may all contain the same aerosol-generating material. Alternatively, at least some of the aerosol-generating strips may include different aerosol-generating materials. For example, at least one aerosol-generating strip may include a first aerosol-generating material, and at least another of the aerosol-generating strips may include a second aerosol-generating material different from the first aerosol-generating material. One or more aerosol-generating strips may include fragrance. Accordingly, aerosols with improved properties and/or user appeal can be produced during use of the aerosol-generating article in an aerosol-generating device. The use of aerosol-generating strips can include, for example, heating different aerosol-generating strips to different temperatures and/or at different heating rates to generate a desired aerosol during use of the aerosol-generating article in an aerosol-generating device. A further advantage is that different regions of the aerosol-generating substrate can be heated in different ways. This is particularly advantageous in embodiments where the aerosol-generating strips include materials different from each other and/or where one or more (but not all) aerosol-generating strips include a fragrance, because they have different properties (e.g. This is because vapors or aerosols with different temperatures, densities, compositions, active ingredients, fragrances, etc.) can be released into different airflow channels. When these vapors or aerosols are mixed, for example, in a portion of the aerosol-generating article downstream of the aerosol-generating substrate formed by the aerosol-generating strip, the properties of the resulting vapor or aerosol may be improved. , and an aerosol with improved appeal to users may be generated.

A substantially flat aerosol-generating substrate can have a flat rectangular shape that can have a pair of major surfaces. The packaging member may include a pair of rectangular sheets that may each be attached to a pair of major surfaces. The aerosol-generating article may have a pleasing aesthetic appearance due to the flat rectangular shape of the aerosol-generating substrate. The aerosol-generating substrate can be easily covered by the packaging member, thereby ensuring that the user does not directly touch the aerosol-generating substrate during handling of the aerosol-generating article. The flat rectangular shape can also facilitate packaging and storage of multiple aerosol generating articles.

In some embodiments in which the aerosol-generating substrate comprises a plurality of aerosol-generating strips, the upper and lower surfaces of the aerosol-generating strips may define major surfaces of the aerosol-generating substrate. The packaging member may be adhered (e.g., by a pharma-ceutically acceptable adhesive) in contact with the upper and lower surfaces of the aerosol-generating strips. Thus, the aerosol-generating strips are secured to the packaging member in a relative position to one another to define airflow channels between the intermittently arranged (i.e., spaced) aerosol-generating strips.

The aerosol product may include a support member that may form a mouth end portion of the article. The support member may have a tubular shape, e.g., a rectangular tubular shape, to receive the downstream end of the aerosol-generating substrate and at least one airflow channel. The support member may be self-supporting and may, for example, comprise cardboard or a plastic material. The support member may advantageously deliver vapor and/or aerosol generated during use of the article directly to the mouth of a user. The support member allows heated vapor generated during use of the aerosol product article to cool and condense to form an aerosol with optimal characteristics for inhalation by a user.

The wrapping member may include a substantially electrically non-conductive and non-magnetically permeable material, such as wrapping paper. The use of wrapping paper facilitates the manufacture and handling of aerosol-generating articles and can increase aerosol generation efficiency.

The packaging member can have a porous inner surface that can face the aerosol-generating substrate to absorb condensation. The porous interior surface may help substantially eliminate or at least minimize the formation of condensation material on the interior surface of the aerosol generating device. The packaging member can have an anti-stick outer surface that can face away from the aerosol-generating substrate. For example, the packaging member may include an anti-stick coating on the exterior surface. The anti-stick outer surface can help ensure that the packaging member does not stick to the surface of the aerosol generating device when heated. Both the porous inner surface and the anti-stick outer surface can reduce the build-up of residue within the aerosol generation device, thus reducing the number of cleaning and maintenance tasks that must be performed by the user of the device.

The aerosol-generating substrate may comprise a non-liquid aerosol-generating material, such as any type of solid or semi-solid material. Exemplary types of aerosol-generating solids include powders, granules, pellets, flakes, strands, particles, gels, strips, loose-leaf, cut-leaf, cut-filler, porous materials, foamed materials or sheets. The aerosol-generating substrate may comprise a plant-derived material, and in particular tobacco. It may advantageously comprise, for example, reconstituted tobacco comprising tobacco and 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-producing articles may be referred to as "heated tobacco devices," "heated non-combustible tobacco devices," "devices for vaporizing tobacco products," etc., and are understood to be devices suitable for achieving these effects. The features disclosed herein are equally applicable to devices designed to vaporize any aerosol-generating substrate.

The aerosol-generating substrate can include an aerosol former. Examples of aerosol formers include polyhydric alcohols such as glycerin or propylene glycol and mixtures thereof. Typically, the aerosol-generating substrate may contain an aerosol former content of about 5% to about 50% on a dry weight basis. In some embodiments, the aerosol-generating substrate can include an aerosol former content of about 10% to about 20% on a dry weight basis, optionally about 15% on a dry weight basis.

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

FIG.

Several embodiments of the present disclosure will now be described, by way of example only, with reference to the accompanying drawings, in which:

1 and 2, a first example of an aerosol product article 1 for use in an electrically operated aerosol generating device 102 is shown, an example of which is described later in this specification with reference to FIG. 9. The aerosol product article 1 is substantially flat and has a distal end 10 and an oral end 12 (or proximal end) at an opposite end of the aerosol product article 1. The oral end 12 is downstream of the distal end 10 with respect to the direction of airflow through the aerosol product article 1, as shown by the three arrows in FIG. 1. A longitudinal axis extends between the distal end 10 and the oral end 12 to define the longitudinal direction of the aerosol product article 1.

The aerosol product article 1 includes a substantially flat aerosol-generating substrate 14. The aerosol-generating substrate 14 includes a bulk or mass of aerosol-generating material and has a flat rectangular shape with a pair of oppositely disposed major surfaces 14a, 14b. The aerosol product article 1 is a consumable or disposable item in which the aerosol-generating substrate 14 may include tobacco or tobacco material.

Aerosol-generating article 1 includes a plurality of airflow channels, which in the illustrated example include a plurality of grooves 18 formed in major surface 14 a of aerosol-generating substrate 14 . The grooves 18 are arranged side by side and parallel to each other, with the grooves 18 extending longitudinally between the distal end 10 and the proximal end 12 substantially parallel to the longitudinal axis. The grooves 18 together form a grooved surface 20. The grooves 18 can be formed by any suitable method, for example, by pressing the main surface 14a of the aerosol-generating substrate 14 with an appropriately shaped pressing tool. Although three grooves 18 are shown in the example of FIGS. 1 and 2, it will be appreciated that any suitable number of grooves 18 may be provided depending, for example, on the desired tensile resistance of the aerosol-generating article 1. It is also noted that groove 18 may have any suitable cross-sectional shape, including, but not limited to, square, rectangular, trapezoidal, or semicircular as shown in FIG.

The aerosol product article 1 further comprises a wrapping member 22 that encloses the aerosol-generating substrate 14 and the groove 18. The aerosol-generating substrate 14 and the groove 18 are thus completely surrounded by the wrapping member 22, which may comprise, for example, tobacco paper or a similar material. The wrapping member 22 comprises a pair of rectangular sheets 24, 26 attached to major surfaces 14a, 14b, respectively, of the aerosol-generating substrate 14. The rectangular sheets 24, 26 are typically formed by a single sheet of material that is wrapped around the aerosol-generating substrate 14 and may have overlapping edges that are bonded together to secure the wrapping member 22 in place around the aerosol-generating substrate 14 and the groove 18.

In an illustrative and non-limiting example, the length of the aerosol-generating substrate 14 (in the longitudinal direction of the aerosol-generating article 1) is about 18.0 mm, the width is about 11.8 mm, and the thickness (or depth) may be approximately 1.2 mm. The aerosol-generating substrate 14 may be spaced inwardly from the distal end 10 of the aerosol-generating article 1 by a small distance, such as about 3.0 mm, as shown in FIG. Aerosol-generating article 1 may be about 12.0 mm wide and about 1.4 mm thick (or deep) to accommodate aerosol-generating substrate 14 within packaging member 22. The aerosol-generating article 1 has a structure in which the distance between the distal end 10 and the mouth-side end 12 is increased by changing the length of the portion of the packaging member 22 that extends between the downstream end and the mouth-side end 12 of the aerosol-generating substrate 14. It can be any suitable length. During use of the aerosol-generating article 1 in the aerosol-generating device 102, as the vapor flows through this portion of the packaging member 22, the vapor can cool and condense to form an aerosol for inhalation by the user. Accordingly, the length of the portion of packaging member 22 that extends between the downstream end of aerosol-generating substrate 14 and the mouth end 12 of aerosol-generating article 1 is selected during manufacture to provide an aerosol with desired properties. can be done.

In some embodiments, the packaging member 22 includes a porous inner surface 22a that faces the aerosol-generating substrate 14 and that can absorb condensation that may form during the heating process. Alternatively or additionally, the packaging member 22 may include an anti-stick outer surface 22b that faces away from the aerosol-generating substrate 14 to reduce the risk of the packaging member 22 sticking to a surface of the aerosol-generating device 102 when heated. The anti-stick outer surface 22b may include an anti-stick coating on the outer surface 22b of the packaging member 22.

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

Aerosol generating article 2 includes a plurality of air flow channels 16 in the form of air flow passages 30 internally formed within aerosol generating substrate 14 . Similar to groove 18, air flow path 30 extends longitudinally between distal end 10 and proximal end 12 substantially parallel to the longitudinal axis. The air flow paths 30 are arranged side by side at approximately the midpoint between the main surfaces 14a and 14b of the aerosol generation base material 14, but each air flow path 30 is completely closed by the aerosol generation material forming the aerosol generation base material 14. Different positions may be adopted, provided that they are surrounded. It is also noted that the air flow path 30 can have a variety of cross-sectional shapes, including, but not limited to, square, rectangular, circular, oval, or triangular as shown in FIG.

Referring now to FIG. 4, a third example of an aerosol generating article 3 is shown. The aerosol-generating article 3 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 3 is positioned at the oral end 12 of the aerosol-generating article 3 to form an oral end portion 34 that can be held in the lips of a user during use of the aerosol-generating article 3 within the aerosol-generating device 102. A support member 28 is included. Support member 28 typically comprises a self-supporting material, such as a cardboard or plastic material, and has a tubular configuration of rectangular cross-section to receive groove 18 formed in the downstream end and surface 14a of aerosol-generating substrate 14. have Wrapping member 22 also surrounds support member 28 .

Referring now to Figures 5 and 6, a fourth example of an aerosol product item 4 is shown. Aerosol product item 4 is similar to aerosol product item 2 described above with reference to Figure 3, and corresponding features are identified using the same reference numerals.

The aerosol product article 4 includes an air flow channel 16 in the form of a single air passage 30 formed internally within the aerosol-generating substrate 14. The air passage 30 extends longitudinally between the distal end 10 and the oral end 12 substantially parallel to the longitudinal axis. The air passage 30 is centrally located within and surrounded on all sides by the aerosol-generating substrate 14, ensuring that volatile components can be released from the aerosol-generating substrate 14 and entrained in air flowing through the air passage 30 during use of the aerosol product article 4 in the aerosol generating device 102.

The aerosol product article 4 is shown without a support member 28 at the mouth end 12. However, a support member 28 may also be provided at the mouth end 12 of the aerosol product article 4, as described above in connection with the aerosol product article 3 of FIG. 4.

Referring now to Figures 7 and 8, there is shown a fifth example of an aerosol product item 5. Aerosol product item 5 is similar to aerosol product items 1, 2, 3, and 4 described above with reference to Figures 1-6, and corresponding features are identified using the same reference numerals.

Within the aerosol product article 5, the aerosol-generating substrate 14 includes a plurality of aerosol-generating strips 32 extending between the distal end 10 and the oral end 12 in a first direction substantially parallel to the longitudinal direction of the aerosol product article 5. The aerosol-generating strips 32 are laterally spaced apart, in other words arranged intermittently and spaced apart in a second direction perpendicular to the first direction. This intermittent arrangement (or spacing) of the aerosol-generating strips 32 results in an airflow channel 16 being formed between each adjacent pair of the aerosol-generating strips 32. Each airflow channel 16 is directly exposed to or in fluid communication with the adjacent aerosol-generating strip 32 that forms the airflow channel 16, meaning that when the aerosol product article 5 is used in the aerosol generating device 102 as described below, vapor or aerosol generated during use of the aerosol product article 5 can flow into the airflow channel 16, be entrained in the airflow through the airflow channel 16, and be delivered to the user during inhalation.

Each of the aerosol-generating strips 32 has an upper and lower surface in use, which together define the major surfaces 14a, 14b of each of the aerosol-generating substrates 14. The packaging member 22 may be attached to the upper and lower surfaces of the aerosol-generating strips 32 by, for example, a pharma- ceutically acceptable adhesive. In this manner, the aerosol-generating strips 32 are secured to the packaging member 22 and in positions relative to one another to define airflow channels 16 between the intermittently arranged (i.e., spaced) aerosol-generating strips 32.

In the illustrated example, aerosol-generating strips 32 all include the same aerosol-generating material. However, in other examples, at least some of the aerosol-generating strips 32 may include different aerosol-generating materials. For example, at least one aerosol-generating strip 32 may include a first aerosol-generating material, and at least another aerosol-generating strip 32 may include a second aerosol-generating material that is different than the first aerosol-generating material. In both examples, at least one aerosol-generating strip 32 may include perfume. By providing an aerosol-generating strip 32 containing different aerosol-generating materials and/or an aerosol-generating strip 32 containing a fragrance, an aerosol with improved user appeal may be generated during use of the aerosol-generating article 5.

Aerosol generating article 5 is shown without support member 28 at oral end 12 . However, the support member 28 can also be provided at the oral end 12 of the aerosol-generating article 5, as described above in connection with the aerosol-generating article 3 of FIG.

9, there is shown an aerosol generation system 100 including an aerosol generation device 102 and a first example of the aerosol product item 1 described above with reference to FIGS. 1 and 2. It will be appreciated that the aerosol generation device 102 may be used in combination with alternative aerosol product items according to the present disclosure, such as the second, third, fourth or fifth examples of the aerosol product items 2, 3, 4, 5 described above with reference to FIGS. 3-8.

Aerosol generation device 102 includes a receiving chamber 106 and a heater 104 disposed within device body 108 to provide heat to receiving chamber 106 . Heater 104 may be a resistance heater or an induction heater that includes a susceptor and an electromagnetic field generator that includes an induction coil.

In use, a user inserts the aerosol-generating article 1 into the receiving chamber 106. Aerosol generation device 102 may include a cover 110 and a pivot 112 that allows cover 110 to be moved between a closed position shown in FIG. 9 and an open position (not shown). As will be understood by those skilled in the art, the user pivots the cover 110 to the open position to allow insertion of the aerosol-generating article 1 into the receiving chamber 106 and then inserts the aerosol-generating article 1 into the receiving chamber 106. In order to hold the cover in place, the cover must be pivoted back to the closed position shown in FIG.

The aerosol generating device 102 includes a power source 114, e.g., a rechargeable battery, and a controller 116, both of which are connected to the heater 104. The heater 104 may be activated manually, e.g., via a user interface, such as a button, on the aerosol generating device 102, or automatically in response to a user drawing on the mouthpiece 118 of the aerosol generating device 102. The aerosol generating device 102 includes one or more air inlets 120 that allow air to flow into the aerosol product article 1 and through grooves 18 formed in the surface of the aerosol generating substrate 14. The direction of air flow is indicated by the arrows in FIG. 9.

With the aerosol-generating article 1 placed in the receiving chamber 106, power is supplied to the heater 104 from the power source 114 (either by manual or automatic activation of the heater 104, as described above), thereby causing the aerosol-generating group to be The material 14 is heated without burning to release one or more volatile components. The volatile components are entrained in the air flowing through the grooves 18, thereby forming vapor. As the vapor flows through channel 18 , it cools and condenses to form an aerosol, which is inhaled by a user through mouthpiece 118 of aerosol generator 102 .

When the aerosol-generating substrate 14 is depleted and no longer emits sufficient volatile components to produce an aerosol of acceptable quality, the aerosol-generating article 1 is moved into the receiving chamber after pivoting the cover 110 to the open position. 106 and a replacement aerosol generating article 1 can be inserted in its place.

When the aerosol generating device 102 is used in combination with an aerosol generating article having a support member 28, such as the third example of the aerosol generating article 3 described above with reference to FIG. By protruding from the open end 106a of the support member 28, the mouth end portion 34 of the aerosol-generating article 3 formed by the support member 28 can be grasped by the user's lips.

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

All possible variations and combinations of the features described above are included in this disclosure unless otherwise indicated herein or otherwise contradicted by context.

Unless the context otherwise requires, throughout this specification and the claims, the words "include", "comprises", and the like are to be construed in their inclusive sense, i.e., "including but not limited to", rather than in their exclusive or exhaustive sense.
