Definitions

  • the present invention relates to a packaging for a smoking substitute apparatus and, in particular, to packaging that is edible and contains a flavourant.
  • the smoking of tobacco is generally considered to expose a smoker to potentially harmful substances. It is generally thought that a significant amount of the potentially harmful substances are generated through the heat caused by the burning and/or combustion of the tobacco and the constituents of the burnt tobacco in the tobacco smoke itself.
  • Such smoking substitute systems can form part of nicotine replacement therapies aimed at people who wish to stop smoking and overcome a dependence on nicotine.
  • Smoking substitute systems include electronic systems that permit a user to simulate the act of smoking by producing an aerosol (also referred to as a "vapour") that is drawn into the lungs through the mouth (inhaled) and then exhaled.
  • the inhaled aerosol typically bears nicotine and/or a flavourant without, or with fewer of, the odour and health risks associated with traditional smoking.
  • smoking substitute systems 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 with combustible tobacco products.
  • vaping in which a vaporisable liquid, typically referred to (and referred to herein) as “e-liquid”, is heated by a heating device (referred to herein as an electronic cigarette or “e-cigarette” device) to produce an aerosol vapour which is inhaled by a user.
  • e-liquid typically includes a base liquid as well as nicotine and/or a flavourant.
  • the resulting vapour therefore also typically contains nicotine and/or a flavourant.
  • the base liquid may include propylene glycol and/or vegetable glycerine.
  • a typical e-cigarette 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.
  • E-cigarettes can be configured in a variety of ways.
  • there are "closed system" vaping smoking substitute systems which typically have a sealed tank and heating element. The tank is prefilled with e-liquid and is not intended to be refilled by an end user.
  • One subset of closed system vaping smoking substitute systems 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, that consumable is disposed of. The main body can be reused by connecting it to a new, replacement, consumable.
  • Another subset of closed system vaping smoking substitute systems are completely disposable, and intended for one-use only.
  • vaping smoking substitute systems which typically have a tank that is configured to be refilled by a user. In this way the entire device can be used multiple times.
  • An example vaping smoking substitute system is the mybluTM e-cigarette.
  • the mybluTM e-cigarette is a closed system which includes a main body and a consumable.
  • 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 heater, which for this device is a heating filament coiled around a portion of a wick.
  • the wick is partially immersed in the e-liquid, and conveys e-liquid from the tank to the heating filament.
  • 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.
  • HT Heated Tobacco
  • HNB heat not burn
  • the tobacco may be leaf tobacco or reconstituted tobacco.
  • the intention is that the tobacco is heated but not burned, i.e. the tobacco does not undergo combustion.
  • the heating, as opposed to burning, of the tobacco material is believed to cause fewer, or smaller quantities, of the more harmful compounds ordinarily produced during smoking. Consequently, the HT approach may reduce the odour and/or health risks that can arise through the burning, combustion and pyrolytic degradation of tobacco.
  • a typical HT smoking substitute system may include a device and a consumable.
  • the consumable may include the tobacco material.
  • the device and consumable may be configured to be physically coupled together.
  • heat may be imparted to the tobacco material by a heating element of the device, wherein airflow through the tobacco material causes components in the tobacco material to be released as vapour.
  • a vapour may also be formed from a carrier in the tobacco material (this carrier may for example include propylene glycol and/or vegetable glycerine) 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 consumable (entrained in the airflow) from the location of vapourisation to an outlet of the consumable (e.g. a mouthpiece), the vapour cools and condenses to form an aerosol for inhalation by the user.
  • the aerosol may contain nicotine and/or flavour compounds.
  • a smoking substitute device it is desirable to deliver nicotine into the user's lungs, where it can be absorbed into the bloodstream.
  • e-liquid is heated by a heating device to produce an aerosol vapour which is inhaled by a user.
  • Many e-cigarettes also deliver flavour to the user to enhance the experience.
  • flavour compounds are contained in the e-liquid that is heated.
  • toxicology restrictions are placed on the amount of flavour that can be contained in the e-liquid, and this can result in some e-liquid flavours delivering a weak and underwhelming taste sensation to consumers in the pursuit of safety.
  • providing a flavourant as part of the e-liquid such that the flavourant is vaporised with the e-liquid, may be disadvantageous.
  • the present invention relates to packaging for a smoking substitute apparatus that is edible and includes a flavourant.
  • a user may put the packaging in their mouth to receive a flavour from the flavourant while using the smoking substitute apparatus.
  • This may provide a convenient mechanism for delivering flavour to the user.
  • flavour may be delivered to a user via the flavour delivery article, rather than through a flavourant contained in an aerosol-former (e.g. e-liquid or tobacco material) of the of the smoking substitute apparatus.
  • an aerosol-former e.g. e-liquid or tobacco material
  • packaging for a smoking substitute apparatus includes non-biodegradable materials (e.g. plastic), which may result in non-biodegradable waste material.
  • non-biodegradable materials e.g. plastic
  • the packaging of the invention addresses this issue, as the packaging may be consumed by the user when the use the smoking substitute apparatus.
  • waste material produced from packaging of smoking substitute apparatuses may be reduced.
  • packaging for a smoking substitute apparatus wherein the packaging is edible and includes a flavourant.
  • the packaging may be made of any suitable edible material.
  • the packaging may define a compartment for receiving the smoking substitute apparatus.
  • the packaging comprises a flavourant.
  • flavourant is used to describe a compound or combination of compounds that provide flavour and/or aroma.
  • the flavourant may be configured to interact with a sensory receptor of a user (such as an olfactory or taste receptor).
  • the flavourant may include one or more volatile substances.
  • the flavourant may be natural or synthetic.
  • the flavourant may include menthol, liquorice, chocolate, fruit flavour (including e.g. citrus, cherry etc.), vanilla, spice (e.g. ginger, cinnamon) and tobacco flavour.
  • the flavourant may be evenly dispersed or may be provided in isolated locations and/or varying concentrations.
  • the flavourant may comprise the edible material itself, or be a constituent of the edible material. Additionally or alternatively, the flavourant may be a flavouring additive which is added to the edible material.
  • the flavourant may be provided in the form of a flavouring additive which is added to the edible material.
  • the flavouring additive may be integrated into the edible material (e.g. during making of the edible material), and/or provided as a coating on a surface of the edible material. Where the flavouring additive is provided as a coating, it may, for example be sprayed or painted onto a surface of the edible material during manufacture of the packaging.
  • the packaging may be dissolvable.
  • the packaging may be arranged to dissolve in a user's mouth. In this manner, when a user puts the packaging in their mouth, the packaging may dissolve and produce a flavour in the user's mouth. This may facilitate flavour delivery to the user, as it may avoid the user having to chew the packaging.
  • the packaging may be arranged to dissolve over a period of time, so that it releases flavour into the user's mouth for that time.
  • the packaging may be see-through. In this manner, a user may easily see the smoking substitute apparatus contained in the packaging. This may avoid the user inadvertently opening a wrong packaging.
  • the packaging may include edible shrink wrap. This may facilitate manufacture of the packaging, and packaging of a smoking substitute apparatus, as conventional packaging techniques may be used.
  • the packaging may include a seaweed material.
  • seaweed-based packaging materials such as those manufactured by Ooho (http://www.oohowater.com/) or Evoware (http://www.evoware.id/) may be used.

  • the packaging may include sheets of rice paper which are assembled to form a compartment for receiving the smoking substitute apparatus.
  • the packaging may include wheat bran.
  • the flavourant may be encapsulated within a plurality of microcapsules, the microcapsules being arranged to disintegrate in the presence of the aerosol generated by the smoking substitute apparatus.
  • the microcapsules encapsulating the flavourant may be disposed on or in an edible material forming the packaging.
  • the microcapsules When the user puts the packaging in their mouth, the microcapsules may enter the user's mouth. Then, when the user inhales an aerosol from the smoking substitute apparatus, aerosol may come into contact with the microcapsules, causing them to disintegrate and release flavourant into the user's mouth.
  • release of the flavourant may be activated by the aerosol, such that flavourant may only be released when the user uses the smoking substitute.
  • the flavourant may be in solid and/or liquid form inside the microcapsules.
  • the microcapsules may include a membrane made of a hydrogel material containing Chitosan.
  • Chitosan is substantially stable around pH 7.5.
  • the Chitosan, and hence the microcapsule's membrane may be stable and retain its integrity for a period of time.
  • an aerosol having a more alkaline pH e.g. an aerosol produced from an e-liquid having a pH around 7.8
  • the change in pH in the user's mouth may cause the Chitosan, and hence microcapsule's membrane, to rapidly break down and release the flavourant contained within.

In this way, power can be supplied by the main body 102 to the filament 111 in order to heat the filament 111.
  • This heat is transferred from the filament 111 to the porous wick 110 which causes e-liquid 104 conveyed by the porous wick 110 to increase in temperature to a point at which it vaporises.
  • the vaporised e-liquid becomes entrained in the airflow and, between the vaporisation point at the filament 111 and the outlet 108 of the passage 106, condenses to form an aerosol.
  • This aerosol is then inhaled, via the mouthpiece 109, by a user of the system 101.
  • the power source of the main body 102 may be in the form of a battery (e.g. a rechargeable battery).
  • the main body 102 may comprise a connector in the form of e.g. a USB port for recharging this battery.
  • the main body 102 may also comprise a controller that controls the supply of power from the power source to the main body electrical contacts (and thus to the filament 111). That, is the controller may be configured to control a voltage applied across the main body electrical contacts, and thus the voltage applied across the filament 111. In this way, the filament 111 may only be heated under certain conditions (e.g. during a puff and/or only when the system is in an active state).
  • the main body 102 may include a puff sensor (not shown) that is configured to detect a puff (i.e. inhalation).
  • the puff sensor may be operatively connected to the controller so as to be able to provide a signal, to the controller, which is indicative of a puff state (i.e. puffing or not puffing).
  • the puff sensor may, for example, be in the form of a pressure sensor or an acoustic sensor.
  • the main body 102 and consumable 103 may comprise a further interface which may, for example, be in the form of an RFID reader, a barcode or QR code reader.
  • This interface may be able to identify a characteristic (e.g. a type) of a consumable 103 engaged with the main body 102.
  • the consumable 103 may include any one or more of an RFID chip, a barcode or QR code, or memory within which is an identifier and which can be interrogated via the interface.
  • Fig. 2 shows a schematic cross-sectional view of a microcapsule 202 containing a flavourant 204.
  • the microcapsule 202 is arranged to disintegrate in the presence of an aerosol generated by a smoking substitute system (e.g. system 101), to release the flavourant 204 contained therein.
  • a plurality of such microcapsules 202 containing flavourant may disposed in and/or on the edible material forming packaging that is an embodiment of the invention (e.g. packaging 120).
  • the microcapsule 202 includes an outer membrane 206 made of a hydrogel composite which contains Chitosan. Chitosan is substantially stable around pH 7.5. Thus, when the microcapsule 202 is placed in a user's mouth, the Chitosan, and hence the outer membrane 206, may be stable and retain its integrity for a period of time. In this manner, the flavourant 204 contained in the microcapsule 202 is not released and so does not produce a flavour in the user's mouth.
  • a nicotine-containing e-liquid may produce an aerosol which has a pH around 7.8.
  • a pH in the user's mouth may increase above pH 7.5, which may cause rapid breakdown of the Chitosan in the outer membrane 206, resulting in disintegration of the microcapsule's outer membrane 206 and release of the flavourant 204.
  • the flavourant 204 in the microcapsule 202 may be in solid or liquid form.
  • the flavourant 204 may be a freeze-dried flavourant.
  • the flavourant 204 may have been freeze-dried to remove moisture from the flavourant 204. This may reduce the risk of flavourant 204 escaping from the microcapsule 202 prior to use.
  • the flavourant 204 may be activated by moisture in the user's mouth (e.g. the flavourant 204 may dissolve in the user's saliva), to produce a flavour in the user's mouth.
  • the outer membrane 206 may include Chitosan having a Deacetylation (DDT) of 75% - 99%.
  • the hydrogel composite forming the outer membrane may, for example, include 0.1% w/w up to 20% w/w of Chitosan.
  • the hydrogel composite may further include excipients such as Xanthan Gum, water, propylene glycol and/or vegetable glycerine.
  • any of the following compounds may also break down upon contacting the aerosol, and so may be included in the hydrogel composite (instead of, or in addition to, Chitosan): Hyaluronic Acid, Dextran, Poly-Acrylamide, Polyacrylic Acid, Guar Gum Succinate, Kappa-Carrageenan, Poly(vinyl Alcohol).
  • the microcapsule 202 may be manufactured by first freeze-drying a flavourant to remove any moisture from the flavourant and produce a flavourant cake.
  • the flavourant cake may be moulded into a desired shape (e.g. a ball) using a mould.
  • Chitosan, together with excipients forming the hydrogel may be then be mixed together to produce the hydrogel composite.
  • the hydrogel composite may be layered in a mould, into which the flavourant cake is inserted.
  • the hydrogel composite may then be rolled to form an outer membrane around the flavourant cake.
  • Packaging according to the invention may contain a plurality of microcapsules 202. After opening the packaging to retrieve a smoking substitute apparatus inside, a user may place the packaging in their mouth, so that the microcapsules 202 are located in the user's mouth. Then, when the user inhales an aerosol from the smoking substitute apparatus, the outer membrane 206 of the microcapsules 202 may disintegrate due to the change in pH caused by the aerosol. This may cause release the flavourant 204 into the user's mouth.
