Description
Title: Apparatus to be used for heating an aerosol generating material to generate an inhalable aerosol and/or gas Description The present invention relates to an apparatus to be used for heating an aerosol generating material to generate an inhalable aerosol and/or gas. The present invention also relates to a method for heating an aerosol generating material to generate an inhalable aerosol and/or gas.
An electronic cigarette, or e-cigarette, is a device that simulates the act of tobacco smoking by producing an inhaled vapor which can bear the appearance, flavor, and feel of inhaled tobacco smoke. Compared to tobacco smoking, e-cigarettes provide a “smoking” experience by reducing the combustion process that occurs when tobacco is burned, resulting in fewer toxins and carcinogens. This is accomplished through the use of heat to vaporize a liquid solution into an inhalable mist. A typical e- cigarette includes a wad of fibers which are soaked with a vaporizable fluid. When the user inhales through the e-cigarette, a heating element is used to heat the fluid soaked fibers, vaporize the fluid, and deliver the vapor.
Many devices for vaping contain a relatively large container to hold the supply of vaping liquid. This means that the consumption can continue for a long time before the container needs to be replaced. By example, vaping devices currently are available with tank sizes of around 4 ml, which may even be modified to contain 6 ml. the so-called e-liquids are available in a wide range of nicotine contents, up to 36 mg/ml, but the use of 16 mg/ml is considered “normal”. Since a regular cigarette contains around 0.8 mg of nicotine (reference Marlboro Red), a 4 ml vaping tank with a 16 mg/ml liquid, delivers a nicotine amount of around 70 cigarettes. For example, a fluid vaporization device is known from US 2014/123989.
Nowadays heat-not-burn tobacco products (HNB) are also in the market. Such a HNB is heated to a lower temperature than when a conventional cigarette is burned. The resulting aerosol contains nicotine and other constituents. These HNB products may match some of the behavioral aspects of smoking. Such products, also known as heated tobacco products, are on consumption only heated rather than burned as with conventional tobacco products The heating process generates a flavorful nicotine-containing vapor. And since the tobacco product does not burn, the levels of harmful smoke constituents seem to be significantly reduced compared to cigarette smoke.
At this moment several heated tobacco products and devices are available in the market, for example IQOS (trademark), Glo (trademark) and TEEPS (trademark). In these systems called the tobacco product is heated just enough to release a flavorful nicotine-containing vapor but without burning the tobacco. The tobacco in a cigarette burns at temperatures in excess of 600°C, generating smoke that contains harmful chemical components. But HNB devices heat tobacco products to much lower temperatures, up to 350°C, without combustion, fire, ash, or smoke.
Because the tobacco is heated and not burned, the levels of harmful chemicals are significantly reduced compared to cigarette smoke. The systems IQOS and Glo are a tobacco heating system with two main components a heated tobacco product and a heating device. To use such a system, a consumer inserts the tobacco product into the heating device, which contains an electronically controlled heater. The consumer pushes a button to turn on the heater, and then draws on the heated tobacco unit to product to inhale the aerosol which is released by the heating device.
In the currently available devices for consuming heat-not-burn tobacco products (HNB), or aerosol generating material, an article with a shape similar to a cigarette, is inserted in the device. Through this action the aerosol generating material present in the article is brought in contact with or close proximity to a heating element. After a number of puffs, the aerosol in the material has been spent, which is mostly indicated by the device. This is either based on time, or number of puffs. Once the article has been spent, it must be removed from the device, and discarded. In the currently available devices for consuming heat-not-burn tobacco products the temperature of the heating element itself is measured and controlled. However, the temperature of the smoke generating material determines the release of nicotine, and potential release of harmful constituents. Controlling the temperature of the heating element therefore is an indirect means of controlling the smoke quality.
There are a number of prior art documents disclosing aerosol- generating devices for consuming or smoking heated smoking articles. Such devices include, for example, electrically heated aerosol- generating devices in which an aerosol is generated by the transfer of heat from one or more electrical heating elements of the aerosol-generating device to the aerosol-forming substrate of a heated smoking article. One advantage of such electrical smoking systems is that they significantly reduce side stream smoke, while permitting a user to selectively suspend and reinitiate smoking. For example, EP 1 059 854 relates to an article for delivering an aerosol to a user, WO 2011/101164 relates to smoking articles in which tobacco is heated rather than combusted.
WO 2016/120344 relates to an apparatus for heating an aerosol generating material to generate an inhalable aerosol and/or gas, the apparatus comprising: a housing; a receptacle within the housing, the receptacle comprising one or more cavities, each cavity for containing an aerosol generating material, and a heating arrangement comprising one or more heater elements for heating aerosol generating material contained in the one or more cavities to generate an inhalable aerosol and/or gas, wherein the one or more heater elements are located externally of the one or more cavities. Such a receptacle comprises a plurality of recesses formed therein, each recess for containing aerosol generating material, the recesses may be arranged in a regular matrix or array.
German Patentschrift DE 43 28 243 relates to a device for inhaling an inhalable substance comprising: a reservoir defining a substantially closed chamber for containing a particulate including a smoking product; a hot carrier gas generator including a heating appliance for heating a carrier gas thereby generating hot carrier gas; means for heating the particulate by convection to a temperature below a glow temperature thereof utilizing the stream of hot carrier gas such that the inhalable substance is released from the particulate; means for at least one of arranging and guiding particles of the particulate such that surfaces of the particles are directly affected by the stream of hot carrier gas; and means for warming volumes of particles of the particulates up to a temperature close to and lower than the glow temperature.
The air outlet nozzle of the hot air generator is directed into the smoking chamber of the smoking device, the outlet being positioned closely to the smoking product in the reservoir. At this point, the heated air reaches a temperature at which the smoking product becomes pyrolytically converted to release aerosols. The quantity of smoking product in the reservoir of the smoking chamber is divided into several discrete quantities and distributed amongst the individual chambers of the reservoir. The drive unit rotates the reservoir so that the discrete quantities of smoking product are sequentially exposed to the hot air jet emerging from the outlet nozzle.
EP 3 453 270 relates to a device for generating an inhalable aerosol and/or gas, the device comprising an aerosol generating material having an integrated electrical resistance heating element, wherein the electrical resistance heating element is at least partially embedded in, or coated by, the aerosol generating material, so that the aerosol generating material may be heated in direct contact with the electrical resistance heating element, wherein the aerosol generating material is provided as a unitary structure and/or coating which may be heated to generate multiple deliveries of an inhalable aerosol and/or gas; wherein the aerosol generating material is a cast or extruded material. The electrical resistance heating element is in the form of a metal mesh, such as copper, aluminum, platinum, tungsten, gold, silver, and titanium, or in the form of a metal alloy, such as nichrome and stainless steel.
US 5,613,505 relates to a heating system for an electrical smoking article for smoking tobacco flavor medium comprising: a generator for producing an alternating magnetic field, a susceptor material which is inductively heatable by the alternating magnetic field and positioned relative to the generator so as to be heatable by the alternating magnetic field, and a tobacco flavor medium in thermal proximity to the susceptor material.
A disadvantage of vaping is that the taste of e-liquids is created by using chemical flavors and aromas. These e-liquids therefore do not convey the taste of aerosol generating articles produced based on organic, plant based, materials.
One such example may be the replacement of tobacco. Heat not burn tobacco consumptions deliver both nicotine as well as a taste very close to the consumption of a traditional cigarette. E-liquids on the other hand may contain nicotine, but the taste deviates much more from traditional smoking.
An object of the present invention is to provide an apparatus to be used for heating an aerosol generating material to generate an inhalable aerosol and/or gas, wherein the aerosol generating material is in the form of a heat-not-burn tobacco product (HNB).
Another object of the present invention is to provide an apparatus to be used for heating an aerosol generating material to generate an inhalable aerosol and/or gas, wherein in the apparatus the heat-not-burn tobacco product (HNB) is provided as a stock of heat-not-burn tobacco products.
The present invention relates to an apparatus to be used for heating an aerosol generating material to generate an inhalable aerosol and/or gas, the apparatus comprising:
a) one or more air inlets for drawing air into a heating chamber, the one or more air inlets are in fluid flow communication with the heating chamber; b) an inlet arrangement comprising an inlet for an aerosol generating material; 5 c) a heating chamber comprising one or more heating elements for heating aerosol generating material, the heating chamber is in fluid flow communication with a mouth piece; d} a mouthpiece through which a user can draw material that has been volatized in the device in the heating chamber; e) power circuitry for powering the one or more heating elements.
The present inventor found that such an apparatus to be used for heating an aerosol generating material to generate an inhalable aerosol and/or gas is capable to deliver an amount of smoke and nicotine equivalent to more than one regular cigarette or current heat not burn article. The inlet arrangement comprises an inlet for an aerosol generating material as a sheet, wherein the sheet is an example of a heat-not-burn tobacco product (HNB}).
In an embodiment the present apparatus further comprises a transporting arrangement, comprising one or more elements for facilitating the transport of the sheet of aerosol generating material from the inlet for an aerosol generating material to the heating chamber.
In an embodiment the present apparatus further comprises a discard arrangement, comprising at least one opening for discarding the spent sheet of aerosol generating material after volatizing the sheet of aerosol generating material in the heating chamber.
In an embodiment the present apparatus further comprises a manual actuator for a user to actuate the power circuitry.
In an embodiment the present apparatus further comprises a sensor for causing actuation of the power circuitry in response to sensing that a user is taking a draw on the apparatus.
In an embodiment the present apparatus further comprises an electrical control circuitry including a controller, such as a microprocessor arrangement, configured and arranged to control the heating elements, wherein the heating elements are chosen from the group of resistive heating elements, infra-red heating elements and inductive heating elements.
In an embodiment the present apparatus further comprises attaching arrangements for attaching a cartridge to the apparatus, wherein the inlet arrangement is in connection with cartridge, the cartridge comprising an aerosol generating material as a sheet.
The cartridge preferably comprises a supply holder provided with the aerosol generating material as a sheet and thus the cartridge can be used for a number of consuming actions. In other words, the cartridge as such is to be seen as a storage for a sheet of aerosol generating material. Such a sheet of aerosol generating material is an example of a heat-not-burn tobacco product (HNB). Thus, the present apparatus uses an aerosol generating material in the form of a sheet. Such a sheet can be divided into discrete parts or can be supplied as a strip or band of aerosol generating material.
The present apparatus is to be seen as a device for consuming a heat-not-burn product. As discussed above, the present apparatus comprises a mouthpiece through which a user can draw material that has been volatized in the device, a heating chamber comprising one or more heating elements for heating aerosol generating material wherein the heating chamber is in fluid flow communication with the mouth piece, and air inlets. Such a heat not burn device may further comprises attaching arrangements for attaching a cartridge comprising an aerosol generating material as a sheet to apparatus. The present apparatus may further comprise transporting arrangements for transporting the sheet of aerosol generating material from the inlet for an aerosol generating material to the heating chamber. By properly attaching the cartridge to the present apparatus the sheet of aerosol generating material is brought into the heating chamber and by heating the sheet of aerosol generating material a step of volatization of the aerosol generating material takes place in the heating chamber. The user can now draw material that has been volatized through the mouthpiece. After a certain time of “smoking” the cartridge can be easily disconnected from the apparatus. In such a case it is possible to use different types of cartridges, for example a cartridge with a menthol flavor, a cartridge with an herbs flavor etc. When the completed amount of sheet of aerosol generating material is spent, the cartridge can be discarded, or re-used or recycled.
A present apparatus to be used for heating an aerosol generating material to generate an inhalable aerosol and/or gas is provided with one or more heating elements. In such an apparatus for consuming a heat-not-burn product, or aerosol generating material, the aerosol generating material is brought into contact or close proximity with the heating elements present in the apparatus. After a number of puffs, the aerosol in the material has been spent, which is mostly indicated by the apparatus. This is either based on time, or number of puffs. The nowadays heat-not- burn products have a shape similar to a cigarette and are inserted into the device for consuming a heat-not-burn product. In contrast with the present invention the heat- not-burn product is a sheet material, i.e. a flat or folded material but not in the form of a cigarette, i.e. a cylindrical tube.
In an embodiment of the present invention the supply holder comprises a rotatably mounted spool around which part of said sheet of aerosol generating material is wound. In such an embodiment the spool comprises a certain “length” of the sheet of aerosol generating material. The transporting arrangement of the present apparatus enables the transportation of the sheet of aerosol generating material through the present apparatus via unwounding the sheet from the rotatably mounted spool.
In another embodiment of the present invention the supply holder comprises a folded strip of the sheet of aerosol generating material. Such a folded strip of the sheet of aerosol generating material may take the form of a zig zag construction, wherein the strip thus folded is a kind of stack of the sheet of aerosol generating material. The transporting arrangement of the present apparatus enables the transportation of the sheet of aerosol generating material through the present apparatus via taking up an end of the sheet from the stack of the sheet of aerosol generating material.
In another embodiment of the present invention the supply holder comprises a stack of individual sheets of aerosol generating material. In such a construction the stack is based on individual sheets of aerosol generating material, which is different from the zig zag construction wherein the sheet of material is a kind of a continuous strip of a sheet of aerosol generating material. The transporting arrangement of the present apparatus enables the transportation of the individual sheets of aerosol generating material through the present apparatus via taking up sheet by sheet from the stack of the sheet of aerosol generating material.
In an embodiment of the present invention the apparatus further comprises a collecting arrangement, comprising a compartment for collecting the spent sheet of aerosol generating material after transportation of the sheet of aerosol generating material through the present apparatus. In such a construction the spent sheet of aerosol generating material may be collected in a cartridge of spent sheet of aerosol generating material and that cartridge can be discarded once all the sheets of aerosol generating material have been used by the consumer.
In an embodiment of the present invention the compartment for collecting the spent sheet of aerosol generating material further comprises a rotatably mounted spool on which the spent sheet of aerosol generating material is collected.
In such a construction the spool enables the collection of the spent sheet of aerosol generating material in a space efficient way.
In another embodiment of the present invention the apparatus further comprises a discard arrangement, comprising at least one opening for discarding the spent sheet of aerosol generating material after transportation of the sheet of aerosol generating material through the present apparatus. In such a construction the spent sheet of aerosol generating material is removed from the apparatus.
According to an embodiment of the present apparatus the transport arrangement provides a batch type of transport of the sheet of aerosol generating material through present apparatus. Such a construction includes the situation that each time the consumer wants to “smoke” a new sheet of aerosol generating material is transported through present apparatus. Such a new sheet of aerosol generating material is subsequently exposed to one or more heating elements. In fact, the new sheet of aerosol generating material equals to one single “smoking action”. After that, the spent sheet of aerosol generating material is transported through present apparatus to the discard arrangement, for example a compartment for collecting the spent sheet of aerosol generating material. In such a batch type of transport of the sheet of aerosol generating material through present apparatus a new sheet is transported for the next “smoking action”.
According to another embodiment of the present apparatus the transport arrangement provides a continuous type of transport of the sheet of aerosol generating material through present apparatus. Such a construction includes the situation that when the consumer wants to “smoke” a well-defined part of the sheet of aerosol generating material is continuously transported through present apparatus and exposed to one or more heating elements. Thus, the transport of the sheet of aerosol generating material enables the continuous exposure of a “fresh” part of the sheet of aerosol generating material to the heating elements. After a complete “smoking action” the spent sheet of aerosol generating material is transported through present apparatus to the discard arrangement, for example a compartment for collecting the spent sheet of aerosol generating material.
In an embodiment of the present apparatus the exposure of the sheet of aerosol generating material to one or more heating elements is in a plane parallel to the one or more heating elements. Such a plane may be flat, but may be curved as well to assure a good contact between sheet and heating element.
In an embodiment of the present apparatus the exposure of the sheet of aerosol generating material is such that the sheet of aerosol generating material is exposed between two arrays of heating elements. Such a passage of the sheet of aerosol generating material enables a uniform heating on both sides of the sheet of aerosol generating material.
In an embodiment of the present apparatus the apparatus further comprises a temperature sensor for measuring the temperature of the aerosol generating material. This may be accomplished via a contactless temperature sensor, for instance Infrared Temperature measurement, or a temperature sensor in contact with the aerosol generating material. The apparatus may further comprise a sensor for measuring the air flow through the apparatus. In an embodiment the power of the one or more heating elements is controlled via a microprocessor for controlling the temperature of the aerosol generating material. Such a control mechanism enables the provision of a certain profile of temperature versus consumption time, which influences the consumption experience. The temperature may also be used to determine the optimal moment and speed for transportation of the sheet of aerosol generating material through present apparatus. The power source for the power circuitry may be a battery, which may be a rechargeable battery or a non-rechargeable battery. Examples include nickel cadmium batteries although any suitable batteries may be used. The battery is electrically coupled to the heater elements of the heating chamber to supply electrical power when required and under control of an electrical control circuitry to heat the aerosol generating material as a sheet.
The present invention also relates to a method for heating an aerosol generating material to generate an inhalable aerosol and/or gas, said method comprising: a) providing an apparatus as discussed above, b) transporting the sheet of aerosol generating material from the inlet arrangement to the heating chamber,
c) exposing the sheet of aerosol generating material to the heating chamber to generate aerosol and/or gas in the heating chamber, d) drawing air into the heating chamber via the air inlets and passing aerosol and/or gas to the mouth piece of a user.
Upon start of consumption, an amount of the sheet of aerosol generating material is released and transported to cover the heating element. The heating is started, and the material is consumed according to certain regime. This regime may be based for example on time, number of puffs taken. Once the consumption has finished, the heating stops. The spent sheet of aerosol generating material may either be replaced by a fresh sheet of aerosol generating material either directly after finishing the consumption, or upon start of the next consumption. The spent sheet of aerosol generating material may be taken out by the consumer, or may be collected.
As discussed above, in an embodiment of the present invention step ¢) is carried out as a batch process. In such an embodiment the size of the heating element of the aerosol generating device may equate to the equivalent surface of one puff. Typically, a traditional cigarette is smoked in on average a number of about 12 puffs. This means that in such an embodiment, the size of the heating element may be approximately 1/12!" of the size of a heating element that covers the complete length of the sheet of aerosol generating material. Each time the consumer takes a puff, a portion of the sheet of aerosol generating material equivalent to one puff is heated. After the puff has ended, that part of the aerosol generating sheet is transported further to replace again the spent the sheet of aerosol generating material by a fresh part of the sheet of aerosol generating material.
As discussed above, in another embodiment of the present invention step c) is carried out as a continuous process. In such an embodiment the sheet of aerosol generating material is transported with a constant speed over the heating element for as long as the consumer draws. The transport speed and the size of the heating element may vary, but this will be designed in such a way that a constant flow of aerosol is generated.
As discussed above, after step d) the spent sheet of aerosol generating material may be collected in the compartment for collecting the spent sheet of aerosol generating material.
As discussed above, after step e) the spent sheet of aerosol generating material may be discarded from the present apparatus.

The sheet of aerosol generating material to be used in the present invention may further contain tobacco and/or another vegetable material included but not limited to Cannabis, cloves, Tendu or various herbs. The sheet of aerosol generating material may contain for example a combination of one or more of glycerol, tobacco extract, nicotine, tobacco extract flavour, binders, thickeners such as alginate, gums and chalk. The heated tobacco product contains a processed tobacco material designed for heating, not for smoking. The tobacco material is made from tobacco plant material, e.g. leaves, which may be processed in the form of reconstituted tobacco. Upon heating, the aerosol generating material releases the aerosol, plus other desired volatile components such as nicotine, tobacco taste components, Tetrahydrocannabinol or THC being the most important psychoactive substance in cannabis, CBD or cannabidiol, specific aroma’s cetera.
