Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir housing, an airflow tube that extends through the reservoir housing, and a folded mesh that is disposed within the airflow tube and includes a plurality of folds. The airflow tube defines a passageway extending therethrough and at least a portion of the airflow tube is permeable to the vaporizable material, in which the permeable portion of the airflow tube is configured to draw vaporizable material from the reservoir housing into the airflow tube for vaporization. The folded mesh is configured to change from a deactivated state to an activated state in response to receiving an electric current, and when in the activated state, the folded mesh is configured to generate an amount of heat that is sufficient to vaporize at least a portion of the vaporizable material drawn from the reservoir housing. Vaporizer devices are also provided.

A stable-foam inhalation-device cartridge for a stable-foam inhalation device which dispenses a stable foam to be consumed by a user. The cartridge is devoid of an electrical energisation component. The cartridge includes a flexible mixing chamber, first and second foam-generation elements, an expansion chamber, a partitioning element having one or more mixing members for agitating a consumable foam and a discharge element. The discharge element has an outlet opening an inlet opening and a discharge conduit which interconnects the inlet opening with the outlet opening. The discharge conduit has a longitudinal extent which locates the inlet opening at a position closer to the partitioning element than to the outlet opening.

A method of treating disorders in a human or animal subject may include heating a material containing a compound to a first temperature to form a heated volume of the material. The method may additionally include heating the heated volume to a higher second temperature to form a dose of vapor including the compound. The method may also include administering the dose of vapor to the subject to treat disorders such as pain. The method may further include pre-heating the material to a preliminary temperature prior to the heating to the first temperature. The heating and pre-heating may be performed with a capsule including two covering layers, each including an electrically conductive material, configured to hold the material therebetween and to generate heat by resistive heating.

Apparatus and methods are described for use with a portion of plant material that includes at least one active ingredient. A vaporizing unit includes a heating element configured to heat the plant material, and a sensor configured to detect an indication of airflow rate through the vaporizing unit. Control circuitry is configured to receive an indication of the airflow rate through the vaporizing unit, and, in response thereto, to determine a smoking profile that is desired by the user. The control circuitry drives the heating element to vaporize the active ingredient of the plant material by heating the plant material according to the determined smoking profile. The control circuitry dynamically updates the smoking profile in response to changes in airflow rate over the course of a smoking session. Other applications are also described.

Phyto material tablets, tablet vaporizers, methods and apparatus for forming phyto material tablets. The tablets are formed to increase vaporization efficiency. Tablets can include break regions to facilitate fracturing into multiple pieces for vaporization. The tablets can also include multiple layers of different phyto material mixtures. Compression molds are used to shape the tablets. The compression molds can be provided on a rotational assembly to facilitate rapid manufacturing of multiple tablets. The vaporizers include heating chambers that are configured to increase the surface area of the tablets exposed for vaporization. The heating chambers include compression or fracture members that compress and/or encourage fracturing of the tablets to assist vaporization.

An inhaler comprising a housing defining a chamber to receive a strip having a plurality of blisters each containing a dose of medicament for inhalation by a user is disclosed. It comprises an inhaler comprising a housing to receive a strip having a plurality of blisters, each blister having a puncturable lid and containing a dose of medicament for inhalation by a user, a mouthpiece mounted to the housing and through which a dose of medicament is inhaled by a user, a blister piercing member mounted for rotation about a first axis and an actuating mechanism including an actuating lever mounted for rotation about a second axis to sequentially move each blister into alignment with the blister piercing member, wherein the actuating lever co-operates with the blister piercing member so that the blister piercing member pivots about said first axis in response to rotation of the actuating member from an initial position about the second axis to puncture the lid of an aligned blister so an airflow through the blister is generated to en-train the dose contained therein and carry it, via the mouth-piece, into the users airway when a user inhales through the mouthpiece. The inhaler comprises an actuating lever load control member to control the force that must be applied to the actuating lever to cause it to rotate from its initial position such that a biasing force is applied to the actuating lever throughout all, or at least a substantial portion of, the stroke of the actuating lever.
