Definitions

  • the present invention relates to a smoking substitute apparatus and, in particular, a smoking substitute apparatus that is able to deliver flavour to a user.
  • 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 pre-filled 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.
  • 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 application is directed towards apparatuses for supplying flavour to a user during the vaping process without needing to resort to flavoured e-liquid, as well as method for manufacturing such apparatuses.
  • the present invention achieves this by encapsulating or otherwise storing flavourant in a component or part of a smoking substitute apparatus which comes into contact with a user's lips during the vaping process.
  • a flavourless e-liquid composition the user is still able to enjoy a pleasant gustatory experience when vaping, for example by licking or sucking on the mouthpiece of the smoking substitute apparatus.
  • a first aspect of the present invention provides a cap for a smoking substitute apparatus, wherein the cap is shaped to conform to an outer surface of the smoking substitute apparatus, and the cap comprises a flavourant.
  • the cap is able to place the cap on the end of the smoking substitute apparatus during use, so that they are able to taste the flavourant while using the smoking substitute apparatus.
  • the cap is removably attachable to a mouthpiece of the smoking substitute apparatus, so that the user can change at will which flavour they taste while using the smoking substitute apparatus.
  • the cap may include a recess for receiving the mouthpiece end of the smoking substitute apparatus, such that an inner surface of the recess conforms to the outer surface of the mouthpiece of the smoking substitute apparatus.
  • the cap also preferably includes a hole at an opposite end to an edge or opening of the recess, such that in use, the hole is aligned with an inlet at the mouthpiece of the smoking substitute apparatus. In this way, when the cap is in placed on the mouthpiece of the smoking substitute apparatus, the inlet through which the user inhales is exposed, so that inhalation is not impeded.
  • the thickness of the cap is uniform or substantially uniform.
  • the thickness of the cap may be such that in use, the whole of an outer surface of the cap is a uniform or substantially uniform distance from the outer surface of the mouthpiece of the smoking substitute apparatus. In this way, the cap forms a neat cover, which varies very little from the shape of the smoking substitute apparatus itself. This effect may also be achieved by the provision of a cap which is shaped such that in use the outer surface of the cap is flush or substantially flush with the outer surface of the mouthpiece of the smoking substitute apparatus.
  • the cap may be formed or partially formed from a flavourant-containing material.
  • the flavourant may be encapsulated in the flavourant-containing material.
  • the flavourant may be encapsulated in microcapsules which form part of the flavourant-containing material.
  • the flavourant-containing material may be a plastic, or a polymer such as low-density polyethylene, high-density polyethylene, polypropylene, polyvinyl chloride, polystyrene, nylon, polytetrafluoroethylene (PTFE, Teflon), polyurethane, polyethylene terephthalate, or silicone.
  • the flavourant-containing material may comprise borosilicate.
  • the flavourant-containing material itself may be edible.
  • the cap may be in the form of a moulded hard sweet, such as a boiled sweet.
  • the cap may be fully edible. In this way, the user can then either suck on, or lick the cap during inhalation, in order to experience the flavour.
  • users may choose to eat the whole cap before inhalation, so that the sweet flavour remains in their mouth during the inhalation process.
  • Caps in such embodiments may include one or more of the following ingredients: sugar syrup (e.g. sucrose, glucose, fructose), citric acid, flavourant, citric acid, gelatin, food colouring, gum.
  • a fully edible cap may be in the form of a softer sweet such as a gummy sweet or a chewy sweet like a Gummi Bear, a Fruit Pastille or a Wine Gum.
  • the cap may be in the form of a moulded piece of chewing gum, which may optionally be swallowable.
  • the user may retain the edible cap in their mouth during inhalation, in order to experience the flavour.
  • the first aspect of the invention relates to an external removable cap which can be placed onto the end of a smoking substitute apparatus.
  • the flavour may be provided in the mouthpiece of the smoking substitute apparatus itself.
  • a second aspect of the invention provides a smoking substitute apparatus having a mouthpiece, wherein the mouthpiece includes a flavourant. This provides similar advantages to the first aspect of the invention, except the flavourant is present in the smoking substitute apparatus itself, rather than being in the form of an external cap. This is advantageous because it means that fewer individual parts are required to achieve the same effect.
  • Many of the optional features set out above with respect to the first aspect of the invention apply equally well to the second aspect of the invention.
  • the mouthpiece of the smoking substitute apparatus may be formed or partially formed from a flavourant-containing material, in which the flavourant may be encapsulated.
  • the flavourant-containing material may be in the form of a polymer such as silicone.
  • the mouthpiece of the smoking substitute apparatus may include a flavourant-containing material which is edible, or the mouthpiece of the smoking substitute apparatus may be fully edible.
  • the third and fourth aspects of the invention relate to methods of manufacturing, respectively, the cap and smoking substitute apparatus of the first and second aspects of the invention, and in particular the means by which the flavourant is added to the material.
  • a third aspect of the invention provides a method of manufacturing the cap of the first aspect of the invention, the method including the steps of: providing a precursor composition, adding a flavourant to the precursor composition to form a flavour-enhanced precursor composition; and forming the cap from the flavour-enhanced precursor composition.
  • the flavourant is able to permeate through the precursor composition before the cap is formed, ensuring an even distribution of the flavourant throughout the precursor composition, and thus in the finished product.
  • the cap is formed using an injection moulding process, and accordingly the precursor composition may be in the form of an injection moulding precursor composition, and the step of forming the cap includes a step of injection moulding of the flavour-enhanced precursor composition.
  • the suitability and advantages of injection moulding for such a process are well known to the skilled person.
  • the fourth aspect of the present invention provides a method of manufacturing the smoking substitute apparatus of the second aspect of the invention, the method including the steps of: providing a precursor composition, adding a flavourant to the precursor composition to form a flavour-enhanced precursor composition; and forming the mouthpiece of the smoking substitute apparatus from the flavour-enhanced precursor composition.
  • the advantages of the fourth aspect of the invention are analogous to the advantages of the third aspect of the invention.
  • the cap is formed using an injection moulding process, and accordingly the precursor composition may be in the form of an injection moulding precursor composition, and the step of forming the mouthpiece includes a step of injection moulding of the flavour-enhanced precursor composition.
  • the precursor composition is generally liquid.
  • the step of adding a flavourant to the precursor composition may include adding a liquid flavourant to the precursor composition, the liquid optionally being in the form of an oil such as an organic oil.
  • the adding step may include a step of adding a solid flavourant, e.g. in the form of a powder or a microencapsulated flavourant, to the precursor composition.
