Dose counting mechanisms for aerosol dispensers

摘要

A dose counting mechanism for an aerosol dispenserDose count mechanismFirst body structure andA second body structure (17) rotatably attached to a first body structure; andAn annular dose counter (15) having a plurality of teeth (15a) along the periphery;The dose counterDisposed in coaxial with the first body structure and the second body structureThe first body structure and the second body structureRotatable against the dose counterAn annular dose counter (15) andA rotatable actuator (19) configured to engage with teeth (15a) of the dose counter (15);Actuator (19) isThe second body structure (17) is configured to trace the perimeter of the dose counter (15) when rotated relative to the first body structureA rotatable actuator (19) andA rotating device (13b) configured to rotate simultaneously with one of the first body structure (3) and the second body structure (17);Rotating deviceThe second body structure (17) is configured to engage with actuator (19) when rotation of the first body structure is startedRotate the actuator (19) around its central axisThereby rotating the dose counter (15) in the first direction;Rotating device (13b) andIncludingDose count mechanism.
