Definitions

  • the cap may be engageable with the body by a sliding mechanism or a threading mechanism. This provides convenient and secure means to move the cap.
  • the device comprises a retainer mechanism to retain the cap in one or more of the first position and the second position. In this way the cap is held more securely in a given position for ease of use, for example to facilitate cleaning of the heating element through the aperture when the cap is in the second position.
  • the device comprises a retainer mechanism to retain the cap in the second position.
  • the retainer mechanism is at least one of a detent mechanism and a magnetic lock mechanism.
  • the retainer mechanism may comprise a catch which holds the cap in one or more of the first and second position when the cap is in that position. The catch may be released when desired by action of the user.
  • the retainer mechanism comprises a magnetic catch, for example comprising magnets in the body and cap respectively between which a magnetic force of attraction exists which holds the cap in position. To move the cap out of the position the user must overcome this force.
  • the retainer mechanism comprises one or more resilient members within the body of the device.
  • the one or more resilient members comprise a catch or detent which engages with a feature of the cap to prevent travel of the cap further from the body than the second position.
  • the resilient members are deformable to disengage the catch or detent, allowing movement of the cap away from the body beyond the second position.
  • deformation of the resilient members is achieved by action of the user.
  • movement of the cap towards the body beyond the first position is prevented by the abutment of a surface of the cap with a surface of the body.
  • an external rim of the cap may abut an external rim of the body.
  • the cap comprises an internal abutment surface which abuts a corresponding internal abutment surface of the body of the device in the first position.
  • the cap is configured with a tactile finish to facilitate gripping of the cap for movement of the cap between the first position and the second position.
  • the tactile finish comprises a high-friction surface covering at least a portion of the cap.
  • the tactile finish comprises one or more raised protrusions, facilitating the engagement of a user's finger or thumb with the cap and the movement of the cap. In this way the user may more easily grip the cap to move it to inspect and/or clean the heating element through the aperture.
  • the cap is biased into the second position. This facilitates movement of the cap into the second position for inspection/cleaning of the heating element.
  • the cap and/or body of the device may comprise biasing means to bias the cap into the second position. For example, when the cap is biased into the second position the user need only disengage a retainer mechanism when the cap is in the first position and the cap will then naturally travel into the second position due to the biasing means.
  • the biasing means comprises a spring.
  • the cap defines plurality of apertures when it is moved away from the body along the longitudinal axis.
  • two apertures are defined, wherein the apertures are defined on opposing sides of the device. This permits the user to access the heating element from either side of the device and further facilitates cleaning by allowing the user to access the heating element through a first aperture, and during cleaning push debris from the heating element out of the second aperture.
  • the device may comprise a body. An end of the body may be configured for engagement with an aerosol-forming article.
  • the body may be configured for engagement with a heated tobacco (HT) consumable (or heat-not-burn (HNB) consumable).
  • HT heated tobacco
  • HNB heat-not-burn
  • the terms "heated tobacco” and “heat-not-burn” are used interchangeably herein to describe a consumable that is of the type that is heated rather than combusted (or are used interchangeably to describe a device for use with such a consumable).
  • the device may comprise a cavity that is configured for receipt of at least a portion of the consumable (i.e. for engagement with the consumable).
  • the aerosol-forming article may be of the type that comprises an aerosol former (e.g. carried by an aerosol-forming substrate).
  • the device may comprise a heater for heating the aerosol-forming article.
  • the heater may comprise a heating element, which may be in the form of a rod that extends from the body of the device.
  • the heating element may extend from the end of the body that is configured for engagement with the aerosol-forming article.
  • the heater (and thus the heating element) may be rigidly mounted to the body.
  • the heating element may be elongate so as to define a longitudinal axis and may, for example, have a transverse profile (i.e. transverse to a longitudinal axis of the heating element) that is substantially circular (i.e. the heating element may be generally cylindrical).
  • the heating element may have a transverse profile that is rectangular (i.e. the heater may be a "blade heater”).
  • the heating element may alternatively be in the shape of a tube (i.e. the heater may be a "tube heater”).
  • the heating element may take other forms (e.g. the heating element may have an elliptical transverse profile).
  • the shape and/or size (e.g. diameter) of the transverse profile of the heating element may be generally consistent for the entire length (or substantially the entire length) of the heating element.
  • the heating element may be between 15 mm and 25 mm long, e.g. between 18 mm and 20 mm long, e.g. around 19 mm long.

  • the thickness of the outer layer may be between 160 ⁇ m and 220 ⁇ m, e.g. between 170 ⁇ m and 190 ⁇ m, e.g. around 180 ⁇ m.
  • the heating element may comprise a heating track, which may extend longitudinally along the heating element.
  • the heating track may be sandwiched between the outer layer and the core of the heating element.
  • the heating track may comprise tungsten and/or rhenium.
  • the heating track may have a thickness of around 20 ⁇ m.
  • the heating element may be located in the cavity (of the device), and may extend (e.g. along a longitudinal axis) from an internal base of the cavity towards an opening of the cavity.
  • the length of the heating element i.e. along the longitudinal axis of the heater
  • the heating element may be less than the depth of the cavity.
  • the heating element may extend for only a portion of the length of the cavity. That is, the heating element may not extend through (or beyond) the opening of the cavity.
  • the heating element may be configured for insertion into an aerosol-forming article (e.g. a HT consumable) when an aerosol-forming article is received in the cavity.

  • an aerosol-forming substrate forming part of an aerosol-forming article (e.g. a HT consumable).
  • the heating element may only penetrate the aerosol-forming substrate, rather than other components of the aerosol-forming article.
  • the heating element may penetrate the aerosol-forming substrate for substantially the entire axial length of the aerosol forming-substrate of the aerosol-forming article.
  • heat may be transferred from (e.g. an outer circumferential surface of) the heating element to the surrounding aerosol-forming substrate, when penetrated by the heating element. That is, heat may be transferred radially outwardly (in the case of a cylindrical heating element) or e.g. radially inwardly (in the case of a tube heater).
  • the heating element of the tube heater may surround at least a portion of the cavity.
  • the heating element may surround a portion of the aerosol-forming article (i.e. so as to heat that portion of the aerosol-forming article).
  • the heating element may surround an aerosol forming substrate of the aerosol-forming article. That is, when an aerosol-forming article is engaged with the device, the aerosol forming substrate of the aerosol-forming article may be located adjacent an inner surface of the (tubular) heating element. When the heating element is activated, heat may be transferred radially inwardly from the inner surface of the heating element to heat the aerosol forming substrate.
