Definitions

  • the present invention relates to smoking substitute devices, and particularly, although not exclusively, to providing smoking substitute devices with flexible seals located at a connection between a main body of the smoking substitute device and a consumable.
  • Such smoking substitute devices can form part of nicotine replacement therapies aimed at people who wish to stop smoking and overcome a dependence on nicotine.
  • Smoking substitute devices which may also be known as electronic nicotine delivery systems, may comprise electronic systems that permit a user to simulate the act of smoking by producing an aerosol, also referred to as a“vapour”, which is drawn into the lungs through the mouth (inhaled) and then exhaled.
  • a“vapour” which is drawn into the lungs through the mouth (inhaled) and then exhaled.
  • the inhaled aerosol typically bears nicotine and/or flavourings without, or with fewer of, the odour and health risks associated with traditional smoking.
  • smoking substitute devices are intended to provide a substitute for the rituals of smoking, whilst providing the user with a similar experience and satisfaction to those experienced with traditional smoking and tobacco products.
  • smoking substitute devices are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end. Other smoking substitute devices do not generally resemble a cigarette (for example, the smoking substitute device may have a generally box-like form).
  • vapourisable liquid typically referred to (and referred to herein) as“e-liquid”
  • e-liquid a vapourisable liquid
  • An e- liquid typically includes a base liquid as well as nicotine and/or flavourings.
  • the resulting vapour therefore typically contains nicotine and/or flavourings.
  • the base liquid may include propylene glycol and/or vegetable glycerin.
  • a typical vaping smoking substitute device includes a mouthpiece, a power source (typically a battery), a tank for containing e-liquid, as well as a heating device.
  • a power source typically a battery
  • a tank for containing e-liquid as well as a heating device.
  • electrical energy is supplied from the power source to the heating device, which heats the e- liquid to produce an aerosol (or“vapour”) which is inhaled by a user through the mouthpiece.
  • Vaping smoking substitute devices can be configured in a variety of ways.
  • there are“closed system” vaping smoking substitute devices which typically have a sealed tank and heating element which is pre-filled with e-liquid and is not intended to be refilled by an end user.
  • One subset of closed system vaping smoking substitute devices include a main body which includes the power source, wherein the main body is configured to be physically and electrically coupled to a consumable including the tank and the heating element. In this way, when the tank of a consumable has been emptied, the main body can be reused by connecting it to a new consumable.
  • Another subset of closed system vaping smoking substitute devices are completely disposable, and intended for one-use only.
  • vaping smoking substitute devices typically have a tank that is configured to be refilled by a user, so the device can be used multiple times.
  • An example vaping smoking substitute device is the mybluTM e-cigarette.
  • the mybluTM e-cigarette is a closed system device which includes a main body and a
  • the main body and consumable are physically and electrically coupled together by pushing the consumable into the main body.
  • the main body includes a rechargeable battery.
  • the consumable includes a mouthpiece, a sealed tank which contains e-liquid, as well as a heating device, which for this device is a heating filament coiled around a portion of a wick which is partially immersed in the e-liquid.
  • the device is activated when a microprocessor on board the main body detects a user inhaling through the mouthpiece. When the device is activated, electrical energy is supplied from the power source to the heating device, which heats e-liquid from the tank to produce a vapour which is inhaled by a user through the mouthpiece.
  • the blu PROTM e-cigarette is an open system device which includes a main body, a (refillable) tank, and a mouthpiece.
  • the main body and tank are physically and electrically coupled together by screwing one to the other.
  • the mouthpiece and refillable tank are physically coupled together by screwing one into the other, and detaching the mouthpiece from the refillable tank allows the tank to be refilled with e-liquid.
  • the device is activated by a button on the main body. When the device is activated, electrical energy is supplied from the power source to a heating device, which heats e-liquid from the tank to produce a vapour which is inhaled by a user through the mouthpiece.

  • a typical HNB smoking substitute device may include a main body and a
  • the consumable may include the tobacco material.
  • the main body and consumable may be configured to be physically coupled together.
  • heat may be imparted to the tobacco material by a heating device that is typically located in the main body, wherein airflow through the tobacco material causes moisture in the tobacco material to be released as vapour.
  • a vapour may be formed from a carrier in the tobacco material (this carrier may for example include propylene glycol and/or vegetable glycerin) and additionally volatile compounds released from the tobacco.
  • the released vapour may be entrained in the airflow drawn through the tobacco.
  • the vapour passes through the smoking substitute device (entrained in the airflow) from an inlet to a mouthpiece (outlet), the vapour cools and condenses to form an aerosol (also referred to as a vapour) for inhalation by the user.
  • the aerosol will normally contain the volatile compounds.
  • HNB smoking substitute devices heating as opposed to burning the tobacco material is believed to cause fewer, or smaller quantities, of the more harmful compounds ordinarily produced during smoking. Consequently, the HNB approach may reduce the odour and/or health risks that can arise through the burning, combustion and pyrolytic degradation of tobacco.
  • the IQOS® smoking substitute device uses a consumable, including reconstituted tobacco located in a wrapper.
  • the consumable includes a holder incorporating a mouthpiece.
  • the consumable may be inserted into a main body that includes a heating device.
  • the heating device has a thermally conductive heating knife which penetrates the reconstituted tobacco of the consumable, when the consumable is inserted into the heating device. Activation of the heating device heats the heating element (in this case a heating knife), which, in turn, heats the tobacco in the consumable.
  • the heating of the tobacco causes it to release nicotine vapour and flavourings which may be drawn through the mouthpiece by the user through inhalation.
  • a second example of the HNB approach is the device known as "Glo"® from British American Tobacco p.l.c. Glo® comprises a relatively thin consumable.
  • the consumable includes leaf tobacco which is heated by a heating device located in a main body. When the consumable is placed in the main body, the tobacco is surrounded by a heating element of the heating device. Activation of the heating device heats the heating element, which, in turn, heats the tobacco in the consumable. The heating of the tobacco causes it to release nicotine vapour and flavourings which may be drawn through the consumable by the user through inhalation.
  • the tobacco when heated by the heating device, is configured to produce vapour when heated rather than when burned (as in a smoking apparatus, e.g. a cigarette).

  • the protruding portion may have a width which is narrower than the generally planar base portion. This can be seen most clearly in Figure 3, where the generally planar base portion extends further than the protruding portion.
  • such a flexible seal can help ensure that the effect of any minor variations in the manufacture of either the consumable 150 or the main body 120 are negated.
  • the air flow rate through the device which is defined at least in part by the spatial separation of the consumable and main body when installed, may be rendered more constant through implementation of the flexible seal.
