Dispensing device

A device for dispensing individual doses of powder from respective pockets of a carrier, the device including:

• a support for a carrier having a plurality of pockets containing respective doses of powder;
• and a mouthpiece through which to inhale an airstream carrying a dose of powder;
• the device further including:
• walls for defining individual respective first flow paths downstream of each pocket of a supported carrier wherein each individual respective first flow path is defined entirely by respective walls unique to that individual respective first flow path, is for connecting the corresponding respective pocket to the mouthpiece and is for deaggregating powder in the airstream.

A device for dispensing individual doses of powder from respective pockets of a carrier, the device including:

• a support for a carrier having a plurality of pockets containing respective doses of powder;
• and a mouthpiece through which to inhale an airstream carrying a dose of powder;
• the device further including:
• walls for defining individual respective first flow paths downstream of each pocket of a supported carrier for connecting the pockets to the mouthpiece and deaggregating powder to the airstream;
• and an arrangement for moving individually each pocket from a respective storage position to a respective discharge position, wherein each pocket, in the respective discharge position, forms an integral part of the individual respective first flow path.

A device for dispensing a dose of powder from a pocket of a carrier, the device including:

• a support for a carrier having a pocket containing a dose of powder;
• and a mouthpiece through which to inhale an airstream carrying a dose of powder;
• the device further including:
• walls defining first and second flow paths communicating with the mouthpiece, the first flow path communicating with the pocket of the supported carrier and the second flow path bypassing the pocket;
• wherein, the walls defining the first flow path include, upstream of the pocket, a portion of relatively reduced cross-sectional areas oriented so as to be directed towards the pocket and direct a relatively high velocity airstream into the pocket.

A device for dispensing individual doses of powder from respective pockets of a pair of carriers, the device including:

• first and second disc shaped carriers, each disc shaped carrier having an annular array of cavities in which respective pockets are formed,
• a first support for the first disc shaped carrier and a second support for the second disc shaped carrier wherein said first and second supports are for rotatably supporting the carriers about a substantially common axis;
• and a dispensing mechanism for releasing into an airstream the powder of a respective pocket of a supported carrier, said dispensing mechanism comprising an arrangement for axially moving, individually, each pocket from a respective storage position to a respective discharge position;
• wherein, in said discharge position, said pocket extends outwardly of said cavity.

A device for dispensing individual doses of powder from respective pockets of a carrier, the device including:

• an indexing mechanism for indexing the carrier between respective pockets, from an opened pocket to an unopened pocket;
• a first counter ring having a first display surface displaying numbers on the first display surface, the first counter ring being rotatable about a counter axis;
• a second counter ring having a second display surface indicating tens counts, the second counter ring being rotatable about the counter axis;
• the first counter ring being driven with the indexing mechanism, wherein the first display surface and the second display surface are planar and perpendicular to the counter axis.
