Dispenser

A dispenser for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source, the dispenser comprising:

• a body for receiving a substance source, the body having a mouthpiece;
• a junction member slideably arranged in the body for movement in a longitudinal axis of the body to release a dose of a substance from a substance source, the junction member comprising a socket for receiving a spout of a substance source;
• a dispenser driver for moving the junction member in the longitudinal axis of the body to release a dose of a substance from a substance source, the dispenser driver comprising a pivot shaft and a cam arranged on the shaft, the dispenser driver being arranged within the body such that rotation of the pivot shaft causes the cam to rotate and apply a force to the junction member so as to move the junction member in the longitudinal axis;
• a cam follower slideably arranged within the body, the cam follower comprising a base and a substantially rigid protrusion extending from the base, the protrusion being arranged between the dispenser driver and the junction member such that a force applied by the cam of the dispenser driver to the protrusion causes the cam follower to slideably move in the longitudinal axis of the body and apply a force to the junction member so as to release a dose of a substance from a substance source;
• a dispenser cap comprising a hollow body having a lower open end engageable with the body, and an upper open end for receiving a cap closure device for closing the upper open end, the upper open end comprising an engageable portion;
• and
• a cap closure device, comprising:
• an upper cap closure portion for engaging with the upper open end of the dispenser cap to close the upper open end of the dispenser cap;
• a lower cap closure portion for engaging with the engageable portion to secure the cap closure device to the dispenser cap;
• and
• a bistable portion connecting the upper cap closure portion and the lower cap closure portion, the bistable portion being switchable between a first stable form in which the bistable portion is extended, and a second stable form in which the bistable portion is collapsed,
• wherein, when the bistable portion is in the second stable form, the upper cap closure portion engages with the upper open end of the dispenser cap to close the dispenser cap.

A dispenser according to any preceding claim, further comprising:

• a breath actuatable valve incorporated with the junction member, for controlling the release of a gas and/or liquid comprising a substance, the valve comprising:
• a flexible tube for receiving a dose of a substance, the tube extending from an inlet end connected to the junction member socket, having a location which is kinkable for closure of the valve in a ready position and moveable to a release position in which the tube is un-kinked for opening of the valve, and having an outlet end moveable for kinking/un-kinking of the tube;
• and
• an outlet member carrying the outlet end of the flexible tube and pivotally connected to the junction member for control of kinking/un-kinking movement of the flexible tube;
• the tube being kinked to an obturating extent when the pivotal outlet member is in a ready position and un-kinked when the pivotal outlet member is moved to a release position.

A dispenser according to any preceding claim, wherein the bistable portion of the cap closure device comprises:

• a substantially rigid separator connected to the upper cap closure portion;
• and
• a resiliently deformable separator having first and second ends, the first end being connected to the substantially rigid separator via a resiliently deformable joint, and the second end being connected to the lower cap closure portion via a resiliently deformable joint,
• wherein the resiliently deformable separator is configured to resiliently deform upon application of a force to the upper cap closure portion and lower cap closure portion so as to permit a change of form of the dispenser cap closure device between the first stable form and second stable form.

A dispenser for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source, the dispenser comprising:

• a body for receiving a substance source, the body having a mouthpiece;
• a junction member slideably arranged in the body for movement in a longitudinal axis of the body to release a dose of a substance from a substance source, the junction member comprising a socket for receiving a spout of a substance source;
• a dispenser driver for moving the junction member in the longitudinal axis of the body to release a dose of a substance from a substance source, the dispenser driver comprising a pivot shaft and a cam arranged on the shaft, the dispenser driver being arranged within the body such that rotation of the pivot shaft causes the cam to rotate and apply a force to the junction member so as to move the junction member in the longitudinal axis;
• a cam follower slideably arranged within the body, the cam follower comprising a base and a substantially rigid protrusion extending from the base, the protrusion being arranged between the dispenser driver and the junction member such that a force applied by the cam of the dispenser driver to the protrusion causes the cam follower to slideably move in the longitudinal axis of the body and apply a force to the junction member so as to release a dose of a substance from a substance source;
• a dose counter for indicating a number of actuations of the dispenser corresponding to a number of doses dispensed from a substance source, or a number of doses remaining in a substance source, the dose counter comprising:
• a first ring member having a first indicia and being rotatable in increments about an axis, the first indicia indicating a count;
• and
• a limiting member comprising a limiting mechanism,
• wherein the limiting mechanism comprises an engaging portion arranged to act radially with respect to the first ring member to contact the first ring member to limit free rotation of the first ring member relative to the limiting member about the axis.

A dispenser for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source, the dispenser comprising:

• a body for receiving a substance source, the body having a mouthpiece;
• a dispenser cap comprising a hollow body having a lower open end engageable with the body, and an upper open end for receiving a cap closure device for closing the upper open end, the upper open end comprising an engageable portion;
• and
• a cap closure device, comprising:
• an upper cap closure portion for engaging with the upper open end of the dispenser cap to close the upper open end of the dispenser cap;
• a lower cap closure portion for engaging with the engageable portion to secure the cap closure device to the dispenser cap;
• and
• a bistable portion connecting the upper cap closure portion and the lower cap closure portion, the bistable portion being switchable between a first stable form in which the bistable portion is extended, and a second stable form in which the bistable portion is collapsed,
• wherein, when the bistable portion is in the second stable form, the upper cap closure portion engages with the upper open end of the dispenser cap to close the dispenser cap;
• a dose counter for indicating a number of actuations of the dispenser corresponding to a number of doses dispensed from a substance source, or a number of doses remaining in a substance source, the dose counter comprising:
• a first ring member having a first indicia and being rotatable in increments about an axis, the first indicia indicating a count;
• and
• a limiting member comprising a limiting mechanism,
• wherein the limiting mechanism comprises an engaging portion arranged to act radially with respect to the first ring member to contact the first ring member to limit free rotation of the first ring member relative to the limiting member about the axis.
