Description

This invention relates to an aerosol-generating article designed to operate in conjunction with an aerosol-generating device. The invention also relates to a method for manufacturing such an aerosol-generating article. In particular, aerosol-generating articles include aerosol-generating substrates that can form aerosols when heated by an aerosol-generating device. Therefore, such types of aerosol-generating devices, also known as heated non-combustible devices, are adapted to generate aerosols for inhalation by heating rather than burning. The popularity and use of risk reduction or risk modification devices (also known as vaporizers) have rapidly increased in recent years as an aid to help habitual smokers who wish to quit smoking conventional tobacco products such as cigarettes, cigars, cigarillos, and hand-rolled tobacco. In contrast to burning tobacco in conventional tobacco products, a variety of devices and systems are available that heat or warm vaporizable material. Commonly available risk reduction or risk modification devices are substrate heating aerosol generating devices or heating non-combustible devices. This type of device generates an aerosol or vapor by heating an aerosol substrate, usually contained in a separate consumable item. Typically, such aerosol generating substrates include moist tobacco leaves or other suitable vaporizable materials at temperatures ranging from 150°C to 350°C. By heating the aerosol generating substrate rather than burning or incinerating it, an aerosol is released that contains the components desired by the user but does not contain by-products from combustion and incineration. Furthermore, aerosols generated by heating tobacco or other vaporizable materials typically do not contain the burnt or bitter taste resulting from combustion and incineration, which can be unpleasant to the user, nor do they contain smoke that can irritate and contaminate the surrounding environment. Aerosol-generating articles usable in such types of aerosol-generating devices can take various forms. Some may be elongated sticks, or other suitable shapes, such as flat shapes. Generally, such aerosol-generating articles are at least partially contained within a heating chamber of a device that includes one or more heaters for heating the aerosol-generating articles. Aerosol-generating articles generally comprise a packaging that encloses an aerosol-generating substrate and a downstream section, also called a cooling section, for cooling the aerosol. The downstream section may include a filter and/or cooling element for cooling the aerosol before it is delivered to the user. Such a filter or cooling element also functions as a support structure, thus ensuring the shape of the downstream section during use of the article. For example, if this shape deforms at least slightly to create a gap between the article and the mouthpiece, air may be drawn along this path instead of passing through the article. This results in a small amount of vapor and hot puff, which is undesirable for the user. Therefore, filters or cooling elements constitute additional components of the article, and their insertion into the downstream portion requires an additional step during manufacturing. As a result, these additional components can give aerosol-generating articles a complex structure, making their manufacture complex and costly. This is a schematic diagram of an aerosol generating assembly comprising an aerosol generating device and an aerosol generating article according to the present invention.Figure 1 is a perspective view of an aerosol-generating article.Figure 1 is a partially disassembled perspective view of an aerosol-generating article.This is a schematic diagram of the manufacturing method according to the present invention. Before describing the present invention, it should be understood that the invention is not limited to the structural details disclosed below. Those skilled in the art who benefit from this disclosure will see that other embodiments of the invention are possible and can be implemented or performed in various ways. As used herein, the terms “aerosol generating device” or “device” may include a vaping device that delivers an aerosol to a user, including an aerosol for vaping, using a heating element described in more detail below. The device may be portable. “Portable” may mean a device used while held by a user. The device may be adapted to generate a variable amount of aerosol by operating a heating element over a variable time period (as opposed to a metered dose of aerosol) and may be controlled by a trigger. The trigger may be user-activated, such as a smoking button and/or an inhalation sensor. The inhalation sensor may also be sensitive to inhalation intensity and duration, enabling the delivery of a variable amount of vapor (to mimic the smoking effect of conventional combustion-type smoking articles such as cigarettes, cigars, or pipes). The device may include a temper
