Definitions

  • the present invention relates to a packing for a smoking substitute device and particularly, although not exclusively, to a smoking substitute system comprising a smoking substitute device and a packaging for the device.
  • 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.
  • Conventional combustible smoking articles such as cigarettes, typically comprise a cylindrical rod of tobacco comprising shreds of tobacco which is surrounded by a wrapper, and usually also a cylindrical filter axially aligned in an abutting relationship with the wrapped tobacco rod.
  • the filter typically comprises a filtration material which is circumscribed by a plug wrap.
  • the wrapped tobacco rod and the filter are joined together by a wrapped band of tipping paper that circumscribes the entire length of the filter and an adjacent portion of the wrapped tobacco rod.
  • a conventional cigarette of this type is used by lighting the end opposite to the filter, and burning the tobacco rod. The smoker receives mainstream smoke into their mouth by drawing on the mouth end or filter end of the cigarette.
  • 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.
  • aerosol also referred to as a "vapour”
  • 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 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.
  • Some smoking substitute systems use smoking substitute articles (also referred to as a "consumables”) that are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end.
  • HT Heated Tobacco
  • HNB Heat not burn
  • the tobacco may be leaf tobacco or reconstituted tobacco.
  • the vapour may contain nicotine and/or flavourings.
  • the intention is that the tobacco is heated but not burned, i.e. the tobacco does not undergo combustion.
  • a typical HT smoking substitute system may include a device and 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 vaporisation 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 will normally contain the volatile compounds.
  • HT smoking substitute systems 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 HT approach may reduce the odour and/or health risks that can arise through the burning, combustion and pyrolytic degradation of tobacco.
  • an HT device is packaged in a standard rigid box such as a cardboard box.
  • the box as known commonly in the art, is usually rectangular in shape and includes a bottom or tray.
  • the tray has a cavity to accommodate the device and/or any other components.
  • the tray is receivable in a lid or cover to secure the top side of the tray.
  • the cover has a construction similar to an inverted tray so as to correspond with the shape of the tray.
  • the tray may be partially or completely receivable in the cover.
  • a major shortcoming associated with these conventional packaging is that a negative pressure may build up between the tray and the cover during the removal of the tray. Furthermore, there is usually no provision to aid a user gripping onto of the tray. As a result, a user may have to hold and shake the cover of the box to detach the tray under its own weight. Consequently, there is a risk that the tray may accidentally or unexpectedly drop out of the cover during such shaking and thereby damaging the device and content stored therein. Further, during an assembling process, the cavity may be pressurised as the tray is inserted into the cover. As a result, the cover may not be able to securely fit onto the tray.
  • the present invention relates to packaging for a smoking substitute system.
  • the packaging comprises an air flow channel to provide fluid communication between the cavity and the external environment, and thereby it may equalise the pressure in the cavity with atmospheric pressure. As a result, such arrangement may allow the tray to be removed from the cover with better efficiency.
  • a packaging for a smoking substitute system comprising a cover and a tray.
  • the tray comprises a cavity for receiving the smoking substitute system.
  • the tray is configured to be peripherally received in the cover such that an air flow channel is defined therebetween.

  • the smoking substitute system may comprise a smoking substitute device, and optionally an aerosol-forming article for use the smoking substitute device.
  • the smoking substitute system may comprises other accessories for the device, such as a cleaning tool, a power source and a user manual.
  • the air flow channel may allow an airflow to enter into the cavity when the tray is being removed the cover by a user, or to purge from the cavity when the tray is being received into the cover during an assembly process.
  • the air flow channel may equalise the pressure in the cavity with atmospheric pressure.
  • the tray may be peripherally received in the cover.
  • the tray may engage with the cover with an interference fit. Such arrangement may allow the cover to be securely mounted on the tray.
  • the packaging may advantageously allow the tray from the cover in an efficient and convenient manner because the tray and the cover may no longer be hold back from each other by a negative pressure or partial vacuum.
  • At least a portion of a sidewall of the tray is configured to space from an adjacent portion of a sidewall of the cover when said tray is received in the cover, so as to define the air flow channel.
  • a gap may be present in between a portion of corresponding sidewalls of the cover and the tray.
  • such arrangement may allow an airflow to flow between the gap and thereby enter or exit the cavity.
  • the sidewalls of the cover and the tray are configured to space from each other by one or more protrusions extending from respective sidewalls of the cover and/or the tray, wherein said air flow channel is defined around the one or more protrusions.
  • one or more protrusions may extend from a sidewall of the cover and abut the corresponding sidewall of the tray, or one or more protrusions may extend from a sidewall of the tray and abut the corresponding sidewall of the cover, or one or more protrusions may extend from the sidewalls of each of the cover and the tray and abut the corresponding sidewalls of the other one of the tray and cover.
  • such arrangement may allow a continuous airflow into the cavity as the user removes the tray from the cover.
  • the sidewalls of the cover and the tray are configured to space from each other by one or more grooves formed on respective sidewalls of the cover and/or the tray, wherein said air flow channel is defined along the one or more grooves.
  • one or more grooves may form on a sidewall of the cover facing a corresponding sidewall of the tray, or one or more grooves may form on a sidewall of the tray and facing a corresponding sidewall of the cover, or one or grooves may form on the sidewalls of each of the cover and the tray and facing the corresponding sidewalls of the other one of the tray and cover.
  • the one or grooves may form along the depth of the respective sidewalls.
  • such arrangement may allow a continuous airflow into the cavity as the user removes the tray from the cover.
  • one or more sidewalls of the cover and/or the tray comprises a corrugated surface having the grooves defined thereon.
  • a corrugated surface may form from a corrugated cardboard having its top liner removed.
  • such arrangement may result in a simplified manufacturing process.
  • one or more corners of the tray is truncated to define the air flow channel.
  • one or more of edges that adjoins adjacent sidewalls of the tray are truncated so as to define the airflow channels, along the truncated edges, towards the corners of the tray.
  • such arrangement may result in a simplified manufacturing process.
  • the airflow channel may comprise one or more vents opened on respective sidewalls of the cover and/or the tray.
  • the one or more vents comprises apertures opened on respective sidewalls of the cover and/or the tray.
  • the one or more vents may open to other airflow channels as described, e.g. as defined around protrusions, along the grooves or along the truncated corners.
  • such arrangement may provide additional air passage and therefore the tray may be removed from the cover more efficiently.
  • the one or more vents opened on a sidewall of the cover aligns with corresponding one or more vents opened on the tray when the tray is received in the cover.
  • the cavity of the tray may be exposed through one or more vents when the tray and the cover are mutually engaged.
  • the one or more vents may allow an airflow to enter the cavity so as to equalise a negative pressure therein. This allows the tray to be separated from the cover in a more efficient manner.
  • the one or more vent each comprises an air permeable valve or membrane for preventing liquid ingress to the cavity.

  • the device 301 comprises a power source in the form of a rechargeable battery (not shown) and a connector in the form of a USB port (not shown).
  • the device 301 further comprises controller (also not shown).
  • the rechargeable battery, connector and controller are similar (and operate in a similar manner) to the corresponding components of the embodiment described above with respect to Figure 2A to 2E .
  • the consumable 302 includes a pair of heater electrical contacts 328 disposed on a device-facing end surface of the consumable 302.
  • the heater electrical contacts 328 are electrically connected to the heater 304 in the consumable 302, such that a voltage applied across the heater electrical contacts 328 generally corresponds to a voltage applied across the resistive heating element of the heater 304.
  • the heater electrical contacts 328 are brought into electrical contact with corresponding device electrical contacts (not shown) on the device 301.
  • the device electrical contacts are electrically connected (directly or indirectly) to the rechargeable battery.
  • the controller may thus be configured to control the voltage applied across the device electrical contacts from the rechargeable battery. By controlling the voltage applied across the device electrical contacts, the voltage applied to the heater 304 is correspondingly controlled.
  • the device 301 includes an output means (forming part of the UI of the system 300) in the form of a single light-emitting diode ("LED") 311.
  • the LED 311 is operatively connected to the controller, such that controller can control the illumination of the LED 311.
  • the controller is configured to illuminate the LED when then the heater 304 is active.
  • the device 301 also includes an input means in the form of a puff sensor (not shown).
  • the puff sensor is the same as that described above with respect to the embodiment shown in Figure 3A to 3E .
