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 use. This could lead to undesirable effects such as malfunctioning of the aerosol generating device.
  • a cap assembly for an aerosol generating device, the cap assembly comprising: a housing including an aperture, the aperture forming the entrance to a consumable-receiving 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, when at the intermediate position, at least a part of the closure is located within the consumable-receiving cavity.
  • 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 has a planar upper surface. In this way, when the closure is in the open position and a consumable is withdrawn from the consumable-receiving cavity by a user, the consumable may move past the closure without catching on the closure which could cause damage to the consumable.
  • the closure includes a first projection and a second projection that are at least partially located respectively within a first projection-receiving cavity of the housing and a second projection-receiving cavity of the housing such that the closure can pivot about the first projection and the second projection.
  • the first projection and the second projection may allow the closure to rotate about the pivot axis relative to the body.
  • the first projection and the second projection may be aligned with the pivot axis. In this way, ease of assembly of the cap assembly may be improved by potentially reducing the number of parts required.
  • the cap assembly further comprises a closure control mechanism configured to control the position of the closure to be bistable such that: 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: 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.
  • ease of operation of the closure may be improved.
  • 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.
  • the closure control mechanism may prevent the consumable-receiving cavity from being accidently exposed which may reduce the likelihood of debris entering the consumable receiving cavity.
  • bistable may be understood to mean a dynamic system that has two stable states. In this case, the open position may be understood to be a first stable state and the closed position may be understood to be a second stable state.
  • 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.
  • different portions of the closure may perform different functions.
  • 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 at least part of the closure that moves through the consumable-receiving cavity is at least part of the first portion of the closure.
  • the first portion of the consumable may move through the consumable-receiving cavity whilst a second portion of the consumable may not move through the consumable-receiving cavity.
  • 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.
  • the consumable-receiving cavity may be substantially cylindrical in shape. Therefore an insertion direction of a consumable into the consumable-receiving cavity may be taken to be a longitudinal or central axis of the cylinder.
  • 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.
  • the cap may automatically move into and be held in the open position. This may be useful, for example, when cleaning the consumable-receiving cavity.
  • the closure control mechanism urges the closure into the closed position.
  • the functionality of the cap assembly may be improved.
  • the cap may automatically move into and be held in the closed position. This may be useful, for example, in preventing unwanted debris from entering the consumable-receiving cavity.
  • the term adopt may be understood to mean reside stably in the referenced position.
  • the term adopt may be understood to mean to move into and then reside stably in the referenced position. For example, if the closure was moved by a user from the intermediate position between the open position and the closed position towards the open position, then there may be a point where the closure would experience a force and/or a torque encouraging it to move towards and then stably reside in the open position. For example, if the closure was moved by a user from the intermediate position between the open position and the closed position towards the closed position, then there may be a point where the closure would experience a force and/or a torque encouraging it to move towards and then stably reside in the closed position.
  • the closure control mechanism includes a lower sub-mechanism positioned to urge the closure into the open position.
  • the functionality of the cap assembly may be improved, for example, by preventing accidental transitioning between the open position and the closed position. This may be useful when cleaning the consumable-receiving cavity.
  • the term lower in this context is used for identification purposes only and should not be interpreted to convey any functional purpose.
  • the closure control mechanism includes an upper sub-mechanism positioned to urge the closure into the closed position.
  • the functionality of the cap assembly may be improved, for example, by preventing accidental transitioning between the closed position and the open position. This may be useful in order to prevent unwanted debris from entering the consumablereceiving cavity.
  • the term upper in this context is used for identification purposes only and should not be interpreted to convey any functional purpose.
  • each sub-mechanism includes a first magnetic element and a second magnetic element wherein the first magnetic element and the second magnetic element are either respectively: a first magnet and a second magnet; or a magnet and a ferromagnetic element; or a ferromagnetic element and a magnet.
  • each sub-mechanism may urge the closure via magnetic attraction between the first magnetic element in a first location and the second magnetic element in a second location.
  • the use of magnetic elements may result in improved durability of the cap assembly.
  • the first portion of the closure contains the first magnetic element of the lower submechanism and the housing contains the second magnetic element of the lower sub-mechanism such that the closure is urged into the open position.
  • a magnetic attraction between the first magnetic element of the lower sub-mechanism and the second magnetic element of the lower sub-mechanism may be the dominant force/torque acting on the closure such that the closure is urged into the open position.
  • the location of the second magnetic element of the lower sub-mechanism in the housing may be chosen such that, when the closure is in the open position, the first magnetic element of the lower sub-mechanism and the second magnetic element of the lower sub-mechanism are in close proximity to one another such that the magnetic attraction between these two magnetic elements dominates any other forces/torques acting on the closure originating from the closure control mechanism.
  • the second magnetic element is positioned adjacent to the consumable-receiving cavity.
  • the orientation of the first magnet relative to the second magnet may be aligned to achieve the designed magnetic attraction. For example, a north pole of the first magnet may need to be orientated to face a south pole of the second magnet in order for there to be magnetic attraction between the first magnet and the second magnet.
  • the orientation of the magnet may be less important because the magnet may be attracted to the ferromagnetic element regardless of which type of pole faces the ferromagnetic element.
  • the second portion of the closure contains the first magnetic element of the upper sub-mechanism and the housing contains the second magnetic element of the upper sub-mechanism such that the closure is biased to adopt the closed position.
  • a magnetic attraction between the first magnetic element of the upper sub-mechanism and the second magnetic element of the upper submechanism may be the dominant force/torque acting on the closure such that the closure is urged into the closed position.
  • the location of the second magnetic element of the upper sub-mechanism in the housing may be chosen such that, when the closure is in the closed position, the first magnetic element of the upper sub-mechanism and the second magnetic element of the upper sub-mechanism are in close proximity to one another such that the magnetic attraction between these two magnetic elements dominates any other forces/torques acting on the closure originating from the closure control mechanism.
  • the first magnetic element of the lower sub-mechanism is a first magnet located in the first portion of the closure and the first magnetic element of the upper sub-mechanism is a second magnet located in the second portion of the closure.
  • the first magnet and the second magnet may be respectively located within a first recess of the closure and a second recess of the closure.
  • the first magnet and the second magnet may be respectively orientated within the first recess of the closure and the second recess of the closure such that the poles of the first magnet are aligned in the same orientation as the poles of the second magnet.
  • aligned may be understood to mean that the poles of the first magnet are configured to point in the same direction as the poles of the second magnet.
  • the first magnetic element of the lower sub-mechanism and the first magnetic element of the upper sub-mechanism form a single magnetic element.
  • the single magnetic element could be a single elongate magnet or a piece of ferromagnetic material that extends through the housing.
  • the piece of ferromagnetic material is a ferromagnetic plate.

  • the ferromagnetic plate is curved away from the consumablereceiving cavity. In some examples, the ferromagnetic plate is angled away from the consumablereceiving cavity.
  • the closure includes a depression positioned such that the depression aligns with the aperture when the closure is in the closed position. In this way, it may be easier for a user to transition the closure from the closed position to the open position using a consumable because an end of the consumable may be guided by the depression. For example, when a user applies pressure to the depression with the end of the consumable. For example, in order to transition the closure from the closed position to the open position.
  • the depression may be included on the first portion of the closure.

  • the part of the closure the recess is shaped to receive is a part of the first portion of the closure.
  • the second magnetic element of the lower sub-mechanism is positioned adjacent to the recess.

  • the closure when in the open position, the closure is offset from a path a consumable takes when the consumable is inserted into the consumable-receiving cavity.
  • a consumable may be inserted into the consumable-receiving cavity more easily, for example, because the movement of the consumable may not be impinged and/or restricted by the closure.
