Definitions

  • 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.
  • 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.
  • vaping 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.
  • 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.
  • a fluid vaporization device is known from US 2014/123989.
  • HNB heat-not-burn tobacco products
  • 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.
  • the tobacco product does not burn, the levels of harmful smoke constituents seem to be significantly reduced compared to cigarette smoke.
  • IQOS trademark
  • Glo trademark
  • TEEPS TEEPS
  • 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.
  • 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.
  • 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.
  • 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.
  • electrical smoking systems are significantly reduce side stream smoke, while permitting a user to selectively suspend and reinitiate smoking.
  • EP 1 059 854 relates to an article for delivering an aerosol to a user
  • WO 201 1/101164 relates to smoking articles in which tobacco is heated rather than combusted.
  • 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.
  • 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.
  • 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.
  • vaping 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.
