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. Embodiments of the present disclosure also relate to methods of making the aerosol product article. The present disclosure is particularly applicable to aerosol product articles for use in portable (handheld) aerosol generating devices.

In recent years, the popularity and use of risk reduction or risk modification devices (also known as aerosol generating devices or vapour generating devices) has grown rapidly 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 produce an aerosol that is inhaled by the user.

A commonly available risk reduction or modification device is the substrate heated aerosol generator, or so-called non-combustion heated device. This type of device generates an aerosol or vapour by heating an aerosol-generating substrate, typically to a temperature in the range of 150°C to 300°C. Heating the aerosol-generating substrate to a temperature within this range, without burning or combusting the aerosol-generating substrate, produces a vapour which typically cools and condenses to form an aerosol for inhalation by the user of the device.

Currently available aerosol generating devices can provide heat to the aerosol generating substrate using one of a number of different techniques, including resistive heating, which utilizes resistive heating elements, and induction heating, which utilizes induction coils and heating elements in the form of inductively heatable susceptors.

Regardless of which technique is used to heat the aerosol generating substrate, the characteristics of the aerosol generated by the aerosol generating device will depend on several factors, including the structure of the aerosol product article used in the aerosol generating device. It is therefore desirable to provide an aerosol product article that allows for optimization of the characteristics of the aerosol generated during use of the article, while at the same time being easy to use in combination with the aerosol generating device.

According to a first aspect of the present disclosure there is provided an aerosol product article for use in an aerosol generating device, the aerosol product article comprising:
an aerosol-generating substrate comprising a plurality of aerosol-generating strips extending in a first direction and intermittently arranged in a second direction perpendicular to the first direction;
a plurality of elongated support elements extending in a first direction along the plurality of aerosol-generating strips and interleaved with the plurality of aerosol-generating strips in a second direction;
A packaging member encircling the plurality of aerosol-generating strips and the plurality of elongated support elements to form a substantially planar aerosol product article.

According to a second aspect of the present disclosure, there is provided a method of producing an aerosol product for use in an aerosol generating device, the method comprising:
providing a plurality of aerosol-generating strips extending in a first direction and disposing the plurality of aerosol-generating strips intermittently in a second direction perpendicular to the first direction;
providing a plurality of elongated support elements extending in a first direction along the plurality of aerosol-generating strips and interleaving the plurality of elongated support elements with the plurality of aerosol-generating strips in a second direction;
and wrapping the plurality of aerosol-generating strips and the plurality of elongated support elements with a packaging member to form a substantially flat aerosol product article.

The aerosol product is for use in an aerosol generating device that heats an aerosol generating substrate, without burning the aerosol generating substrate, to volatilize at least one component of the aerosol generating substrate, thereby producing a heated vapor that is cooled and condensed to form an aerosol for inhalation by a user of the aerosol generating device. The aerosol generating device is a handheld, portable device.

Generally speaking, a vapor is a substance that is in the gas phase below its critical temperature, meaning that it can be condensed into a liquid by increasing the pressure without decreasing the temperature, while an aerosol is fine solid particles or liquid droplets suspended 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.

The elongated support elements help to maintain the structural rigidity and cross-sectional shape of the aerosol product article, in particular by resisting or preventing deformation of the aerosol generating strip. By providing a plurality of elongated support elements extending in a first direction, the risk of deformation of the aerosol product article, e.g. due to crushing or compression of the aerosol product article, during processing and/or storage and/or handling of the aerosol product article is minimized. Thus, the risk of blocking the air flow route, e.g. provided by the air flow channel, during processing and/or storage and/or handling of the aerosol product article is also minimized. By providing a packaging member surrounding the aerosol generating strip and the support elements, the vapour and/or aerosol generated during use of the aerosol product article in the aerosol generating device flows inside the article along the air flow route, e.g. the air flow channel, before being inhaled by the user. This can help to ensure that the maximum possible amount of vapour and/or aerosol is delivered to the user and that the delivered vapour and/or aerosol has optimal properties.

The elongated support element may comprise a material having a higher strength or stiffness or rigidity than the aerosol-generating strip. Deformation of the aerosol-generating strip is thereby inhibited or prevented by the elongated support element. The elongated support element may comprise any one of paper, molded pulp, metal, woven (e.g., cloth), nonwoven or flame-retardant wood. Each of these materials may offer several advantages. For example, paper offers advantages including light weight, low cost, workability, temperature resistance and low risk of emitting unwanted volatile components (i.e., controllable generation), molded pulp offers advantages including light weight, workability, temperature resistance and strength (compared to ordinary paper), metal offers advantages including temperature resistance, high thermal conductivity and low risk of emitting unwanted volatile components (i.e., controllable generation), woven or nonwoven fabric offers advantages including low cost, temperature resistance and low risk of emitting unwanted volatile components (i.e., controllable generation), and flame-retardant wood offers advantages including workability, temperature resistance and strength (compared to ordinary paper).

The aerosol product may include a distal end, a mouth end (or mouth end), and a longitudinal axis that may extend between the mouth end and the distal end. The mouth end (or mouth end) is located at an end of the aerosol product product opposite the distal end. More specifically, during use of the aerosol product product, for example in an aerosol generating device, i.e. when a user inhales through the mouth end (or mouth end) during use, the mouth end (or mouth end) is located downstream of the distal end with respect to the direction of airflow through the aerosol product product. Thus, the mouth end (or mouth end) constitutes a downstream portion of the aerosol product product. The first direction may be substantially parallel to the longitudinal axis. Thus, the support member may extend in a direction substantially parallel to the longitudinal axis between the distal end and the mouth end. Air flows through the aerosol product product from the distal end to the mouth end during use of the aerosol product product, thereby ensuring that a maximum amount of volatile components are released into the air from the heated aerosol generating strip. This therefore ensures that the maximum possible amount of vapor and/or aerosol is generated and delivered to the user during use of the aerosol product.

The elongated support element may be longer than the aerosol generating strip in the first direction. The elongated support element may extend beyond the end of the aerosol generating strip to form the mouth end (or mouth end) of the aerosol product article. This may help to improve the rigidity and structural integrity of the aerosol product article at the mouth end (or mouth end) where the aerosol product article is engaged by the lips of a user.

The packaging member may form a pair of major surfaces that may have a substantially flat shape, and at least one of the major surfaces may be spaced from the aerosol generating strip to form a gap between the major surface and the aerosol generating strip, and the gap may extend in a first direction along the aerosol generating strip to form an airflow channel. The airflow channel provides a route for aerosol and/or vapor to flow within the aerosol product article, thereby substantially eliminating or at least minimizing the formation of condensed matter on the interior surface of the aerosol generating device.

One of the major surfaces of the packaging member may be in contact with the plurality of elongated support elements so as to be spaced from the aerosol generating strip, thereby forming said gaps. Thus, the gaps, and therefore the air flow channels, are readily formed during the manufacture of the aerosol product by contact between the major surface of the packaging member and the elongated support elements.

One of the major surfaces of the packaging member may contact the plurality of aerosol generating strips and the plurality of elongate support elements. This may help to facilitate correct positioning of the packaging member relative to the aerosol generating strips and the support elements.

The plurality of aerosol generating strips and the plurality of elongated support elements may form a flat rectangular shape that may have a pair of major surfaces. The packaging member may include a pair of rectangular sheets that may be attached to the pair of major surfaces, respectively. The aerosol product article may have a pleasing aesthetic appearance due to the flat rectangular shape of the aerosol generating substrate formed by the plurality of aerosol generating strips. The aerosol generating strips that form the aerosol generating substrate may be easily covered by the packaging member, thereby preventing a user from directly touching the aerosol generating strips during handling of the aerosol product article. The flat rectangular shape may also facilitate packaging and storage of the plurality of aerosol product articles.

The aerosol product article may include a support member that may form the mouth end of the article. The support member may have a tubular form, for example a rectangular tubular form, to receive the aerosol generating strip and the downstream end of the elongated support element. The support member may be self-supporting and may for example comprise cardboard or a plastic material. The support member may advantageously deliver the vapour and/or aerosol generated during use of the article directly to the mouth of the user. The support member may allow heated vapour generated during use of the aerosol product article to cool and condense to form an aerosol with optimal properties for inhalation by the user.

The packaging member may comprise a substantially electrically non-conductive and non-magnetically permeable material, for example a paper wrapper. The use of a paper wrapper may facilitate manufacturing and handling of the aerosol product and may enhance aerosol generation.

The packaging member may have a porous inner surface that may face towards the aerosol generating strip for absorbing condensation. The porous inner surface may help to ensure that the formation of condensation on the inner surface of the aerosol generating device is substantially eliminated or at least minimized. The packaging member may have an anti-stick outer surface that may face away from the aerosol generating substrate, more specifically away from the aerosol generating strip. For example, the packaging member may include an anti-stick coating on the outer surface. The anti-stick outer surface may help to prevent the packaging member from sticking to the surface of the aerosol generating device when the aerosol generating device is heated. Both the porous inner surface and the anti-stick outer surface may help to reduce the build-up of residue within the aerosol generating device, thus reducing the number of cleaning and maintenance tasks that may have to be performed by users of the device.

The aerosol-generating substrate, and more particularly the aerosol-generating strip, 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, shreds, strands, particles, gels, loose-leaf, cut-leaf, cut-filler, porous materials, foamed materials or sheets. The aerosol-generating strips may comprise plant-derived materials, and in particular tobacco. These may advantageously comprise reconstituted tobacco, for example comprising tobacco and any one or more of cellulose fibres, tobacco stem fibres and inorganic fillers such as CaCO3.

Accordingly, an aerosol-generating device intended for use with an aerosol product article may be referred to as a "heated tobacco device," "heated non-combustion tobacco device," "device for vaporizing a tobacco product," or the like, and the device is to be interpreted as a device 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 may include an aerosol-forming agent. Examples of aerosol-forming agents include polyhydric alcohols, such as glycerin or propylene glycol, and mixtures thereof. Typically, the aerosol-generating substrate may include an aerosol-forming agent content of about 5% to about 50% on a dry weight basis. In some embodiments, the aerosol-generating substrate may include an aerosol-forming agent content of about 10% to about 20% on a dry weight basis, and sometimes about 15% on a dry weight basis.

The aerosol product article may be configured for use with an electrically powered aerosol generating device that includes a heater. The heater may be a resistive heater or an inductive heater. Upon heating, the aerosol generating strip that forms the aerosol generating substrate may release volatile compounds. The volatile compounds may include flavor compounds such as nicotine or tobacco flavorings.

FIG. 13 is a schematic longitudinal cross-sectional view of a third example of an aerosol product. 1 is a schematic cross-sectional view of an aerosol generation system including an aerosol generating device and an aerosol product according to the present disclosure. FIG.

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 powered aerosol generating device 102 is shown. This example is described later in this specification with reference to FIG. 5. The aerosol product article 1 is substantially flat and has a distal end 10 and an oral end 12 (or proximal end) at the 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 represented 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 plurality of aerosol-generating strips 32 extending between the distal end 10 and the mouth end 12 in a first direction substantially parallel to the longitudinal direction of the aerosol product article 1. The aerosol-generating strips 32 are spaced apart laterally. In other words, the aerosol-generating strips 32 are intermittently and spaced apart in a second direction perpendicular to the first direction. The aerosol-generating substrate 14 formed by the aerosol-generating strips 32 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 strips 32 may include tobacco or tobacco material.

The aerosol product article 1 includes a plurality of air flow channels 16, which in the illustrated example include a plurality of grooves 18 formed in the major surface 14a of the aerosol-generating substrate 14. The grooves 18 are arranged next to each other in parallel, and the grooves 18 extend longitudinally between the distal end 10 and the oral end 12 substantially parallel to the longitudinal axis. The grooves 18 may be formed in any suitable manner, for example by providing a reduced amount of aerosol-generating strip 32 in the area in which the grooves 18 are formed. Although three grooves 18 are shown in the example of Figures 1 and 2, it will be understood that any suitable number of grooves 18 may be provided, for example depending on the desired resistance to draw of the aerosol product article 1. It should also be noted that the grooves 18 may have any suitable cross-sectional shape, including but not limited to a rectangular, square, trapezoidal, or semicircular shape as shown in Figure 2.

The aerosol product 1 includes a plurality of elongated support elements 20, which also extend in a first direction between the distal end 10 and the oral end 12, substantially parallel to the aerosol generating strips 32 and substantially parallel to the longitudinal direction of the aerosol product 1. The support elements 20 are laterally spaced apart and, more specifically, interleaved with the aerosol generating strips 32 in a second direction. In a first example of the aerosol product 1 shown in Figures 1 and 2, the support elements 20 have a substantially circular cross-sectional shape. In a second example of the aerosol product 2 shown in Figure 3, the support elements 20 have a rectangular cross-sectional shape. Other cross-sectional shapes, including, for example, square and elliptical, are within the scope of the present disclosure. The support elements 20 include a material having a higher stiffness or rigidity than the aerosol generating strips 32 and thus help maintain the structural rigidity and shape of the aerosol product 1, 2.

As can be seen in FIG. 1, the support element 20 is longer than the aerosol-generating strip 32 and extends beyond the downstream end of the aerosol-generating strip 32 toward the mouth end 12. The support element 20 thus forms the mouth end 34 of the aerosol product article 1.

The aerosol product article 1 further includes a packaging member 22 that encloses the aerosol-generating strip 32 and the support element 20. The aerosol-generating strip 32 and the support element 20 are completely enclosed by the packaging member 22, which forms a flat rectangular shape having a pair of major surfaces 44, 46 and may include, for example, cigarette paper or a similar material. The packaging member 22 includes a pair of rectangular sheets 24, 26 attached to the major surfaces 44, 46, respectively. The packaging member 22 is typically formed by a single piece of material that is wrapped around the aerosol-generating strip 32 and the support element 20 and may have overlapping edges that are bonded together to secure the packaging member 22 in place.

The packaging member 22 forms a pair of major surfaces 40, 42 having a substantially flat shape. The major surface 40 contacts the aerosol-generating strip 32 and the support element 20 at the major surface 44. The major surface 42 contacts the support element 20 but is spaced from the aerosol-generating strip 32 to form a series of gaps 36 between the major surface 42 and the aerosol-generating strip 32. Each gap 36 extends in a first direction between the distal end 10 and the mouth end 12 that is substantially parallel to the aerosol-generating strip 32 and substantially parallel to the longitudinal direction of the aerosol product 1. Each gap 36 forms an airflow channel 16 (or groove 18) as described above.

In an illustrative and non-limiting example, the aerosol-generating substrate 14 formed by the aerosol-generating strip 32 may have a length (in the longitudinal direction of the aerosol product article 1) of about 18.0 mm, a width of about 11.8 mm, and a thickness (or depth) of about 1.2 mm. The aerosol-generating strip 32 may be spaced inwardly from the distal end 10 of the aerosol product article 1 by a small distance, for example about 3.0 mm, as shown in FIG. 1. The aerosol product 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 strip 32 inside the packaging member 22. The aerosol product article 1 may have any suitable length between the distal end 10 and the mouth end 12 by varying the length of the portion of the packaging member 22 that extends between the downstream end of the aerosol-generating strip 32 and the mouth end 12, and by similarly varying the length of the support element 20. During use of the aerosol product 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. Thus, the length of the portion of the packaging member 22 and support element 20 that extends between the downstream end of the aerosol generating strip 32 and the mouth end 12 of the aerosol product article 1 can be selected at the time of manufacture to provide an aerosol having desired characteristics.

In some embodiments, the packaging member 22 includes a porous inner surface 22a facing towards the aerosol-generating substrate 14 that can absorb condensation that may form during the heating process. Alternatively or in addition, the packaging member 22 may include an anti-stick outer surface 22b facing 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.

The above aerosol product items 1, 2 can be manufactured by (i) providing a plurality of aerosol generating strips 32 extending in a first direction and disposing the aerosol generating strips 32 intermittently in a second direction, and (ii) providing a plurality of elongated support elements 20 extending in the first direction and disposing the elongated support elements 20 alternating with the plurality of aerosol generating strips 32 in the second direction. It should be noted that steps (i) and (ii) can be performed in any order or simultaneously. The final step of the manufacturing method includes (iii) wrapping the aerosol generating strips 32 and the elongated support elements 20 with a packaging member 22 to form a substantially flat aerosol product item 1, 2.

Referring now to FIG. 4, a third example of an aerosol product item 3 is shown. Aerosol product item 3 is similar to aerosol product items 1 and 2 described above with reference to FIGS. 1-3, and corresponding features are identified using the same reference numbers.

The aerosol product article 3 includes a support member 28 disposed at the mouth end 12 of the aerosol product article 3 to further define a mouth end 34 that can be engaged by the lips of a user during use of the aerosol product article 3 in the aerosol generating device 102. The support member 28 typically includes a self-supporting material, such as cardboard or a plastic material, and has a rectangular tubular configuration in cross section to receive the aerosol generating strip 32 and the downstream end of the support element 20. The packaging member 22 also surrounds the support member 28.

5, there is shown an aerosol generation system 100 including an aerosol generation device 102 and a first example of the aerosol product 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 products according to the present disclosure, such as the second or third examples of the aerosol product 2, 3 described above with reference to FIGS. 3 and 4.

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

In use, a user inserts the aerosol product item 1 into the storage chamber 106. The aerosol generating device 102 may include a cover 110 and a pivot mount 112 that allows the cover 110 to be moved between a closed position shown in FIG. 5 and an open position (not shown). As will be appreciated by those skilled in the art, the user must pivot the cover 110 to the open position to allow insertion of the aerosol product item 1 into the storage chamber 106, and then pivot the cover back to the closed position shown in FIG. 5 to hold the aerosol product item 1 in place within the storage chamber 106.

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 may be activated automatically in response to a user inhaling on the mouthpiece 118 of the aerosol generating device 102. The aerosol generating device 102 includes one or more air inlets 120 for allowing air to flow into the aerosol product article 1 and through the airflow channel 16. The direction of the airflow is indicated by the arrows in FIG. 5.

With the aerosol product article 1 disposed within the containment chamber 106, power is applied from the power source 114 to the heater 104 (either by manual or automatic actuation of the heater 104 as described above), thereby heating the aerosol generating strip 32 without combustion and releasing one or more volatile components. The volatile components are entrained in the air flowing through the airflow channel 16, thereby forming a vapor. As the vapor flows through the airflow channel 16, it cools and condenses to form an aerosol that is inhaled by the user through the mouthpiece 118 of the aerosol generating device 102.

When the aerosol generating strip 32 is used and no longer emits sufficient volatile components to generate an aerosol of satisfactory quality, the aerosol product item 1 can be removed from the receiving chamber 106 after the cover 110 is pivoted to an open position and a replacement aerosol product item 1 can be inserted in its place.

When the aerosol generating device 102 is used in combination with an aerosol product having a support member 28, such as the third example of aerosol product 3 described above with reference to FIG. 4, the support member 28 may protrude from the open end 106a of the containing chamber 106, thereby allowing the user's lips to engage the mouth end 34 of the aerosol product 3 formed by the support member 28.

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

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

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