Dispenser

A dispenser for a gaseous, gas borne or droplet substance contained in a source thereof, the dispenser including:

• a body with a mouthpiece;
• a junction member in the body for the substance source;
• and
• a breath actuable valve, for controlling the release of the gas or liquid containing or comprising the substance, the valve comprising:
• a flexible tube for receiving the said gas or liquid, the tube extending from a valve inlet connected to the junction member and having a portion which is kinkable for closure of the valve and movable to an open position in which the tube is un-kinked for opening of the valve;
• and
• a member arranged for movement in the body by inhalation to un-kink the valve;
• the tube being kinked to an obturating extent when the movable member is in a ready position and un-kinked when the movable member is moved on inhalation for release of the gas or liquid;
• wherein the dispenser also includes:
• a spring for assisting the movement to un-kink the tube and
• means to hold the movable member in the ready position to close the tube by kinking prior to inhalation.

• the tube being kinked to an obturating extent when the movable member is in a ready position and un-kinked when the movable member is moved on inhalation for release of the gas or liquid;
• wherein the dispenser also includes:
• means for locating the source in the body with the junction member being slidable towards it and
• means to cock the breath actuable valve to a condition in which the movable member is moved to the ready position, the cocking means including:
• a cocking lever pivotally mounted on the body and operatively connected to the movable member.

• the tube being kinked to an obturating extent when the movable member is in a ready position and un-kinked when the movable member is moved on inhalation for release of the gas or liquid;
• wherein:
• the junction member is slidably mounted in the body for movement in a direction for dispensing a dose of the substance from the source against resilient urging of a spring in the source and
• the dispenser includes:
• means for locating the source in the body with the junction member being slidable towards it,
• means for pivoting the flap to its ready position on or prior to initial movement of the junction member,
• a button arranged on the body opposite the source and movable towards the source with abutment against the junction member and with compression of the spring in the source for displacing the junction member towards the source for dispensing the dose into the kinked tube and
• an actuator having:
• an first abutment movable with the button against the flap for pivotal movement of the flap on initial movement of the button;
• a second abutment movable with the first abutment against a fixed point in the dispenser for limiting the movement of the first abutment member and
• a spring acting between the button and the abutments for causing the limited movement of the latter on-movement of the button and allowing further movement of the button for movement of the junction member for dispensing a dose into the tube kinked on its pivotal movement.

A dispenser for a gaseous, gas borne or droplet substance contained in a source thereof having an outlet movable for release of the substance, the dispenser comprising:

• a body with a mouthpiece;
• a rigid connection between the body and the source;
• a substance junction movably arranged in the body for the substance outlet;
• a breath actuatable mechanism for controlling the dispensing of the gas or liquid containing or comprising the substance from the substance outlet to the mouthpiece;
• and
• a cocking lever for cocking the breath actuatable mechanism.
