An inhaler is provided, comprising a housing which contains a blister strip having a plurality of blisters which contain powdered medicament for inhalation; a mouthpiece mounted on the housing through which the medicament is inhaled by a user; an actuator; a blister piercing member; an indexing wheel for sequentially moving each blister into alignment with the blister piercing member when the user operates the actuator; an actuator gear, mounted for rotation about a first axis, which is driven by the actuator and which comprises an actuator gear element; and a drive gear for driving the indexing wheel, mounted for rotation about a second axis, which engages with the actuator gear element. The inhaler is characterized in that the gear ratio between the actuator gear element and the drive gear varies as they rotate during operation of the actuator.

A rupturing system for an aerosol-generating system is provided, the rupturing system including a first tube and a second tube being movable relative to each other along a first motion path from a first position to a second position, such that the defined volume is larger in the first position than in the second position; a rupturing member connected to one of the first tube and the second tube, the rupturing member being arranged such that in the first position the rupturing member is contained completely in the defined volume of the first tube and the second tube, and in the second position the rupturing member at least partially protrudes from the defined volume and is configured to rupture a container; and a first wrapper overlying at least a portion of the first tube and being attached to the first tube.

An aerosol-generating system (50) has an optical sensor (23) disposed on a portion of an exterior surface of the aerosol-generating system. The optical sensor is configured to output sensor data. A controller (29) is operably coupled to the optical sensor. The controller is configured to manipulate one or more operating parameters of an aerosolizer element of the aerosol-generating system based on the optical sensor data.

A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

There is provided a dose counter assembly for use with a medicament dispenser, the dose counter assembly comprising: a) a units dose display means comprising a first count indicia and one or more driver teeth; b) a tens dose display means comprising a second count indicia; and c) a driver, wherein the first count indicia and second count indicia align at a common viewing area to collectively display a count sequence.

A nicotine powder delivery system includes an inhaler article and a nicotine powder capsule disposed within the inhaler article. The nicotine powder capsule rotates about a longitudinal axis when air flows through the inhaler article.

There is provided an inhaler article (10) having an upstream end (1) and a downstream end (2). The inhaler article comprises an upstream section (3) which comprises an end plug (5). The inhaler article comprises a downstream section (4) located downstream of the upstream section and spaced apart from the upstream section. The downstream section comprises a filter segment (6). The resistance to draw per unit length of the filter segment is greater than 0 millimetres of water per millimetre and less than about 3 millimetres of water per millimetre. The inhaler article comprises a cavity (7) defined between the upstream and downstream sections, and configured to be in fluid communication with the exterior of the article. The inhaler article comprises a capsule (9) containing an inhalable material, and located in the cavity. There is also provided an inhaler system (100) comprising such an inhaler article and a holder (120).

An inhaler for inhalation of an inhalable dry powder is provided. The inhaler has (a) an outer shell having a first shell part and a second shell part; (b) a capsule holder having a chamber for holding a capsule, a capsule breaker for breaking open a capsule held within the chamber and a trigger for causing the capsule breaker to break open a capsule; (c) a support for supporting the capsule holder; and (d) an outlet for passage of dry powder from the capsule into a user. The capsule holder is positioned in the first shell part which has an aperture through which the trigger protrudes. The aperture has a cut-out in the rim of the first shell part and through which the trigger may pass when the capsule holder is removed from the first shell part. The support has one or more first mating parts for mating with one or more second mating parts on the first shell part, the first and second mating parts preventing outward movement of the walls of the first shell part when the first and second mating parts are mutually engaged.

A method for producing a cartridge is proposed, where a fluid is filled into an opening of a container and a closure part is inserted into the container, thereby moving a movable piston arranged within the container.

A piercing device (150) contains a recessed piercing element (160) and is configured to receive a distal end (118) of an inhaler article (110). The piercing element pierces or punctures a single hole into a capsule contained within the inhaler article when the inhaler article is seated into an inhaler article cavity (157) of the piercing device. The piercing device includes a marking element (170) extending into the inhaler article cavity from the housing inner surface (152). The marking element is configured to mark an outer surface of an inhaler device when the inhaler device is received within the inhaler article cavity. The marking element extends orthogonally to the piercing element longitudinal axis.
