Described herein are an interactive apparatus and methods for sensing and measuring real-time characteristic patterns of a subject's use of a dry powder inhalation system. The inhaler device can be used in a wireless communication mode to communicate with a display to assess the subject's usage of the inhalation system concurrently as the inhalation is performed and thus the subject's inhalation can be evaluated as well as the performance of the inhalation system. The system can also detect the identity of the medicament, its dosage, lot, expiration, etc. and the characteristics profile of a dry powder formulation emitted from the inhalation system in use.

An aerosol-generating system including a liquid storage portion is provided, the portion including a rigid housing holding a liquid aerosol-forming substrate, the housing having an opening and a fluid permeable heater assembly including a plurality of electrically conductive filaments, wherein the fluid permeable heater assembly is fixed to the housing and extends across the opening of the housing. The provided heater assembly that extends across an opening of a liquid storage portion allows for a robust construction that is relatively simple to manufacture and allows for a large contact area between the heater assembly and liquid aerosol-forming substrate. The heater assembly may be substantially flat, allowing for simple manufacture.

An inhaler article includes a body extending along a longitudinal axis from a mouthpiece end to a distal end, a mouthpiece air outlet and a distal air inlet, and a capsule cavity within the body and bounded downstream by a mouthpiece. A separator is between the capsule cavity and the mouthpiece including at least one aperture to form an air flow path from the distal air inlet through the capsule cavity, through the mouthpiece to the mouthpiece air outlet. A coating layer of flavour is disposed on an interior surface of the mouthpiece and a protective layer disposed on the coating layer of flavour.

An inhaler article includes a body extending along a longitudinal axis from a mouthpiece end to a distal end and a capsule cavity defined within the body. A mouthpiece air channel extends from the capsule cavity to the mouthpiece end. An end cap is disposed within the distal end and extends to the capsule cavity. The end cap extends from an end cap distal end to an end cap inner end. The end cap includes an air channel extending from the end cap distal end to the end cap inner end. The air channel is non-parallel with the longitudinal axis.

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.

Features relating to a vaporizer body are provided. The vaporizer body may include an outer shell that includes an inner region defined by an outer shell sidewall. A support structure is configured to fit within the inner region of the outer shell. The support structure includes a storage region defined by a top support structure, a bottom support structure, a bottom cap, and a gasket. An integrated board assembly is configured to fit within the storage region of the support structure. The integrated board assembly may include a printed circuit board assembly formed of multiple layers that form a rigid structure and that include an inner, flexible layer. A first antenna is integrated at a proximal end of the flexible layer, and a second antenna is integrated at a distal end of the flexible layer.

A heating device is provided that creates inhalable aerosol that includes one or more heating elements and a temporary or permanently established cavity formed by a barrier between the heating elements and the external environment that envelops the heating elements to allow the insertion and removal of consumables from the cavity and allows for the replacement of the heating elements in the device.

Methods and apparatus are described for delivering API to a smokable structures and tea bags that contain a fill material. The fill material can include cannabis plant matter, such as cannabis flowers. In one example, an injection tube can be inserted into a smokable structure, and the API can be emitted as a spray. Other methods examples of delivering API to smokable structures are disclosed.

There is provided a device for an electronic aerosol provision system, wherein the device includes a housing, the housing being formed of a chassis section and a hatch section. The hatch section is connected to the chassis section and moveable between a first position wherein the chassis section and hatch section together define an enclosed space for an aerosol forming component to be located for aerosol generation, and a second position wherein the chassis section and hatch section are spaced so as to provide access to the space.

In the field of medical dosing device filling, a propellant conditioning assembly (10) comprises an input conduit (12) to receive a propellant at a constant pressure from a propellant reservoir (102). The conditioning assembly (10) also includes a bifurcation (18) to divide the input conduit (12) into first and second conditioning conduits (20, 22). The first conditioning conduit (20) includes a cooler device (24) to selectively cool a diverted first propellant stream (26) that flows through the first conditioning conduit (20), and the second conditioning conduit (22) includes a heater device (32) to selectively heat a diverted second propellant stream (34) that flows through the second conditioning conduit (22). The conditioning assembly (10) still further includes an output conduit (44) to receive the first and second propellant streams (26, 34). The relative proportion of the first and second propellant streams (26, 34) merging in the output conduit (44) is controlled to regulate the temperature of a merged constant pressure propellant feed (46) exiting from the output conduit (44).
