A heating system for an inhaler device, such as an e-cigarette or a personal vaporizer, for generating an aerosol and/or a vapor from a substance to be heated, especially a liquid or gel, the heating system including: a first heating zone configured to receive the substance to be heated from a supply reservoir, wherein at least one first heating element is provided to pre-heat the substance in the first heating zone; and a second heating zone configured to receive the preheated substance from the first heating zone, wherein at least one second heating element is provided to heat the substance in the second heating zone.

Heating system and method of heating for an inhaler device

A delivery device is provided having a container containing a dose of greater than 40 mg of a powder and having at least one exit orifice for dispensing the dose from the container, a chamber adapted to receive the container in an operative configuration, at least one gas inlet by which gas may enter the chamber and at least one gas outlet by which gas and entrained powder may exit the chamber. The delivery device is operable to generate a gas flow through the chamber between the at least one gas inlet and the at least one gas outlet, which brings about orbital motion of the container within the chamber in that at least a central region of the container orbits a central axis of the chamber.

Delivery devices

A heating system for an inhaler device, such as an e-cigarette or a personal vaporizer, for generating an aerosol and/or a vapor from a substance to be heated includes at least one supply channel for conveying a substance to be heated, especially a liquid solution or a gel, from a supply reservoir by or under capillary action or surface tension forces, and a heater configured to heat the substance as it is conveyed through the at least one channel.

A heating system () for an inhaler device (), such as an e-cigarette or a personal vaporizer, for generating an aerosol and/or a vapor (V) from a substance to be heated, especially a liquid or gel, the heating system () including: a first heating zone () configured to receive the substance to be heated from a supply reservoir (), wherein at least one first heating element () is provided to pre-heat the substance in the first heating zone (); and a second heating zone () configured to receive the preheated substance from the first heating zone (), wherein at least one second heating element () is provided to heat the substance in the second heating zone ().

A delivery device is provided which has a container containing a dose of a powder, a chamber adapted to receive the container, at least one gas inlet by which gas may enter the chamber, and at least one gas outlet by which gas and entrained powder may exit the chamber for inhalation. The delivery device has a pre-use configuration in which the container is accommodated, at least partially, within a storage enclosure in a wall of the chamber. The delivery device has a deployment member adapted to put the delivery device in an operative configuration by displacing the container from the storage enclosure into the chamber, such that the container is movable within the chamber, in use, the deployment member being adapted to at least partially occupy the storage enclosure in the operative configuration.

A delivery device is provided which comprises a container containing a dose of a powder and having at least one exit orifice for dispensing the dose from the container and a chamber adapted to receive the container in an operative configuration. The device further comprises at least one gas inlet by which gas may enter the chamber and at least one gas outlet by which gas and entrained powder may exit the chamber. The delivery device is operable to generate a gas flow through the chamber between the at least one gas inlet and the at least one gas outlet, which brings about orbital motion of the container within the chamber in that at least a central region of the container orbits a central axis of the chamber. The volume occupied by the container is at least 25% of the volume of the chamber.
