Description

The present disclosure relates to a shisha device and a cartridge comprising an aerosol-forming substrate used in the shisha device, and more specifically, to an absorbent carrier impregnated with an aerosol-forming body used in such a cartridge.

Traditional shisha devices are used to smoke cigarettes and are configured to allow vapors and smoke to pass through the basin before being inhaled by the consumer. The shisha device may include one outlet, or may include two or more outlets so that the device may be used simultaneously by two or more consumers. The use of shisha devices is considered by many to be an entertaining and social experience.

Tobacco used in shisha devices may be mixed with other ingredients, for example to increase the amount of vapor produced and smoke, and / or to change the flavor. In conventional shisha equipment, charcoal pellets are typically used to heat tobacco, which may burn tobacco or other components completely or partially. In addition, charcoal pellets can generate harmful or potentially harmful products such as carbon monoxide, which can mix with shisha vapor and pass through the basin. May be done.

Some shisha devices have been proposed to consume tobacco using an electric heating source, for example to avoid by-products of charcoal burning or to improve the consistency of tobacco heating. Other shisha devices that employ e-liquid instead of tobacco have been proposed. Shisha equipment that employs e-liquid removes by-products from combustion, but deprives shisha consumers of the traditional tobacco-derived experience.

Other shisha devices have been proposed that employ electric heaters that heat but do not burn tobacco. Such a heated non-combustible shisha device reduces or eliminates by-products associated with tobacco combustion. However, such devices may suffer from reduced aerosol production compared to conventional charcoal-derived shisha devices. Aerosol formation may refer to any of the visible aerosols, aerosol masses, aerosol volumes, or any combination thereof. Therefore, such devices may not meet the user's expectations for a traditional shisha experience. The reduction in aerosol formation may be more pronounced during the initial smoke absorption. The reduced aerosol production may be due to inefficient thermal conductivity between the heater and the tobacco-derived substrate.

Some heated non-combustible shisha devices are used in combination with a substrate that substantially deviates from conventional tobacco-derived molasses. For example, the substrate for electronic shisha may contain dried stone or e-liquid. These substrates usually have a more homogeneous form than molasses and a higher thermal conductivity than molasses. Molasses tends to be relatively more inhomogeneous and is therefore difficult to heat uniformly. However, users may perceive that non-molasses substrates exacerbate typical practices and experiences.

The inefficient thermal conductivity between the electric heater and the substrate may result in an overall low amount of total aerosol material (TAM), especially during the first to 20 smoke absorptions.

It would be desirable to provide an aerosol generation system for electroheated shisha devices that improves aerosolization. It would also be desirable to provide an aerosol generation system for an electrically heated shisha device that increases TAM. It would be even more desirable to provide an aerosol generation system for electrically heated shisha devices that reduces the time it takes for the user to absorb the first smoke (the time to the first smoke absorption, also referred to as TT1P). It is also more desirable to provide an aerosol generation system that allows the use of conventional substrates (eg, molasses) while improving aerosolization, increasing TAM, and reducing TT1P. It will be.

Various aspects of the invention relate to a shisha cartridge comprising a body defining a cavity and an internal cavity surface. The cartridge comprises an aerosol-forming substrate placed in the cavity. The cartridge comprises an absorbent carrier placed in a cavity. The absorbent carrier may form a sheet. The absorbent carrier is impregnated with a volatile aerosol-forming body. The absorbent carrier is adjacent to the internal cavity surface, or adjacent to the aerosol-forming substrate, or adjacent to both the internal cavity surface and the aerosol-forming substrate (eg, between the internal cavity surface and the aerosol-forming substrate). It may be stationary. When the cartridge and the volatile aerosol-forming body in the absorbent carrier are heated during use, the aerosol-forming body evaporates to form an aerosol.

According to one aspect of the present disclosure, an absorbent carrier impregnated with an aerosol-forming body is immobilized inside the cartridge in order to improve aerosolization and release of the sensory active compound from the aerosol-forming substrate. The absorbent carrier may be impregnated with one or more aerosol-forming bodies. Optionally, the absorbent carrier may also be impregnated with one or more sensory active compounds or precursors thereof. Aerosol-forming bodies are compounds that facilitate the formation of aerosols during use. Such compounds include, but are not limited to, glycerin and propylene glycol. Sensory-active compounds are compounds that make it possible to elicit a sensory response, such as flavoring agents.

According to some embodiments, the absorbent carrier may be placed adjacent to the inner surface of the cavity. For example, the absorbent carrier may be in direct contact with the heated surface when the cartridge is in use, along the walls of the cartridge (such as the side walls), at the bottom of the cartridge, or along the top of the cartridge. Or any combination of these may be stationary. In a preferred embodiment, the absorbent carrier comes into direct contact with the surface to be heated when the cartridge is in use.

As used herein, the term "sheet" is used to refer to a material that is generally flat and has a width and height greater than the thickness of the material (eg, orders of magnitude larger). An example of a sheet is a piece of paper. Of course, the term "sheet" may also include materials that are thicker than paper. The sheet of material may be bent, folded, crimped, crumpled, or otherwise.

The absorbent carrier may take any form or shape. The absorbent carrier may be flat, curved, rolled, bent, pleated, crimped, crumpled, bent, etc., or in multiple forms. It may include a combination of shapes (eg, a flat portion and a pleated or bent portion).

When the cartridge and the absorbent carrier inside the cartridge are heated during use, the aerosol-forming body impregnated (eg, absorbed) in the absorbent carrier vaporizes partially or entirely. The vaporized compound contributes to the formation of the aerosol. Aerosol-forming bodies may improve aerosolization by increasing the total aerosol material generated by the Shisha device, especially during the first few smoke absorptions. Therefore, when aerosol production similar to that of a charcoal-derived shisha device is obtained using a heated non-combustible shisha device that uses a conventional substrate (moraces) and employs an absorbent carrier impregnated with an aerosol-forming body. There is. This helps to preserve as much flavor, aroma, and convention as possible associated with conventional shisha devices and substrates. In the absence of an absorbent carrier impregnated with a volatile aerosol-forming body, conventional moraces substrates are compared to conventional charcoal-heated shisha equipment in heated non-combustible shisha equipment, especially during the first few smoke absorptions. May result in a relatively low amount of total aerosol mass.

For example, TT1P can be approximately 17 minutes (including a preheating time of 4 minutes) when using a cartridge that employs molasses without an absorbent carrier impregnated with an aerosol-forming body. However, by using an aerosol-forming body impregnated in an absorbent carrier to increase the amount of aerosol available during the first few smoke absorptions, TT1P is reduced by about 1 minute to about 15 minutes. May be done. In some embodiments, the (reduced) TT1P is about 5 minutes or longer, about 8 minutes or longer, or about 10 minutes or longer. The (reduced) TT1P may be about 15 minutes, up to about 12 minutes, or up to about 10 minutes.

Example Example 1:
The effect of the absorbent carrier impregnated with the aerosol-forming body on aerosol formation was evaluated. An absorbent carrier was placed inside the cartridge to form a sheet (cellulose paper) with a surface area of ^{40 cm 2} impregnated with about 1.5 g of a 1: 1 mixture of plant glycerin and propylene glycol. The absorbent carrier had a cylindrical shape positioned adjacent to the inner wall of the cartridge. The cartridge was then filled with 10 g of commercially available molasses (Al-Fakher) inside a cylinder of porous material. Control samples were prepared without an absorbent carrier impregnated with aerosol-forming material.

The cartridge was inserted into a test shisha device, where the cartridge was heated to a set point temperature of 200 ° C. using a ceramic resistance heating element. The set point temperature of the heater was chosen so that the molasses (between smoke and smoke absorption) would be similar to the shisha operated on charcoal.

To improve the aerosolization process, a finned nozzle made of aluminum with an outlet orifice of about 3 mm in diameter was placed about 55 mm from the heating engine.

The generated aerosol was collected using a total of 5 Cambridge pads and the weight of the pads was recorded before and after the test. At any given time point during the test, only one of the pads collects the generated aerosol.

The total duration of the smoking test corresponds to 105 smoke inhalations. To achieve the desired smoke-absorbing experience, four programmable dual syringe pumps (available from PDSP, Pomac B.V. (Tourbat, The Netherlands)) were used simultaneously to create a smoke-absorbing regime. The smoke absorption regime was as follows, and samples and controls were tested for 105 smoke absorptions. The number of smoke inhalations is divided into five contiguous portions of each of the 21 smoke inhalations, and the aerosol from each portion is collected in a separate Cambridge pad. After every 21 smoke absorptions, the valve ensures that the aerosol is distributed to the correct Cambridge pad. As a result, aerosol formation can be monitored over time.

The results of the total aerosol mass (TAM) collected over the first 21 smoke absorptions and a total of 105 smoke absorptions of the control and sample are shown in Tables 1 and 5 below. Results for the first 21 smoke aspirations are calculated as mg per smoke aspiration, and results for the total duration of the test (15 smoke aspirations) are given as cumulative total mass in mg.

It was observed that a significant increase in aerosol generation due to the use of the absorbent carrier impregnated with the aerosol-forming body was achieved not only during the first 21 smoke absorptions, but throughout the experiment. The total TAM accumulated during the test was also higher on the absorbent carrier impregnated with the aerosol-forming material.

Therefore, a cartridge for a shisha device is described. Various modifications and variations of the invention will be apparent to those skilled in the art without departing from the scope and gist of the invention. Although the invention has been described in the context of certain preferred embodiments, of course, the invention as claimed should not be unreasonably limited to these particular embodiments. In fact, various modifications of the described method for carrying out the present invention, which are apparent to those skilled in the art of mechanical technology, chemical technology, and aerosol-generating articles manufacturing or related fields, are claimed below.
