Definitions

  • the present disclosure relates to a cap assembly for an aerosol generating device.
  • a typical aerosol generating apparatus may comprise a power supply, an aerosol generating unit that is driven by the power supply, an aerosol precursor, which in use is aerosolised by the aerosol generating unit to generate an aerosol, and a delivery system for delivery of the aerosol to a user.
  • a drawback with known aerosol generating devices is that debris may enter a consumable-receiving cavity of the aerosol generating device between uses. Such debris could lead to undesirable effects such as malfunction of the aerosol generating device.
  • the present disclosure provides a cap assembly for an aerosol generating device, the cap assembly comprises an actuator and a cap, the cap being moveable relative to the actuator, wherein the cap comprises: a housing including an aperture, the aperture forming the entrance to a consumablereceiving cavity; and a closure pivotably mounted adjacent to the aperture and selectably pivotable relative to the housing about a pivot axis to adopt an open position where the aperture is exposed and a closed position where the aperture is occluded; wherein the closure moves through an intermediate position when transitioning between the open position and the closed position; and the closure transitions from the open position to the closed position when the cap is moved from a first position relative to the actuator to a second position relative to the actuator.
  • the closure may be transitioned from the open position to the closed position by moving the actuator relative to the cap which may be more convenient for a user, for example, because they do not have to physically interact with the closure itself in order to transition it which may be more difficult than simply moving the actuator relative to the cap.
  • the orientation of the closure in the open position is perpendicular to the orientation of the closure in the closed position. In this way, the cap assembly may be made more compact.
  • the closure includes a first projection and a second projection that are each respectively located within a first projection-receiving cavity of the housing and a second projectionreceiving cavity of the housing such that the closure can pivot about the first projection and the second projection. In this way, ease of assembly of the cap assembly may be improved, for example, by reducing the number of parts required.
  • At the intermediate position when at the intermediate position, at least a part of the closure is located within the consumable-receiving cavity. In this way, a consumable may be inserted into the consumablereceiving cavity without first needing to set the closure to the open position. As such, for example, a consumable may be used to transition the closure from the closed position to the open position.
  • Transitioning between the open position and the closed position should be understood to include moving from the open position to the closed position and also moving from the closed position to the open position.
  • the cap assembly further comprises a closure control mechanism configured to control the position of the closure to be bistable such that, when the cap is in the first position: the open position is a stable equilibrium position; the closed position is a stable equilibrium position; and the intermediate position is an unstable equilibrium position.
  • a closure control mechanism configured to control the position of the closure to be bistable such that, when the cap is in the first position: the open position is a stable equilibrium position; the closed position is a stable equilibrium position; and the intermediate position is an unstable equilibrium position.

  • the closure may only naturally reside in either the open position or the closed position so a user may only have to move the closure past the unstable equilibrium position in order to transition the closure from one position to another.

For example, when the cap is in the second position, the closure may only naturally reside in the closed position allowing the user to transition the closure from the open position to the closed position simply by moving the cap.
  • the closure control mechanism may include, for example, one or more magnetic elements, one or more springs and/or one or more flexible membranes. One or more of these elements may be combined in order to control the position of the closure to be bistable.
  • the closure includes a first portion and a second portion located on opposing sides of the pivot axis.
  • a first portion of the closure may selectively occlude or expose the entrance to the consumable-receiving cavity.
  • a second portion of the closure may function as a handle allowing a user to transition the closure between the open position and the closed position.
  • the pivot axis is perpendicular to an insertion direction of a consumable into the consumable-receiving cavity.
  • the closure may pivot along the insertion direction of the consumable.
  • the insertion direction of a consumable may be understood to mean the direction traced by an end of the consumable as it moves from the entrance of the consumable-receiving cavity to a base of the consumable-receiving cavity.

  • a consumable may be used to transition the closure from the closed position to the open position.
  • the closure control mechanism urges the closure into the open position.
  • the functionality of the cap assembly may be improved.
