Abstract: A dose indicator device for a pressurized metered dose inhaler comprises an inner wheel, annular outer wheel, actuator and housing; the inner wheel comprising primary indexing teeth and a flexible drive arm; the outer wheel comprising secondary indexing teeth on an outer face of the outer wheel; the inner wheel and outer wheel located at least partially within the housing such that the inner wheel and outer wheel are rotatable about a common longitudinal axis of rotation; the actuator movable in a plane perpendicular to the axis of rotation to engage the primary indexing teeth to rotate the inner wheel; the housing being fixed relative to the axis of rotation and comprising a deflector; the deflector configured such that, on rotation of the inner wheel, the drive arm is intermittently deflected and brought into contact with the secondary indexing teeth to rotate the outer wheel about the axis of rotation.

Abstract: A fluid delivery device for discharging a fluid having a housing, a piston pump, a biasing mechanism, and a trigger mechanism. The housing has a fluid discharge outlet. The pump has a pump chamber casing for fluid storage, a piston sliding in the pump chamber, a piston plunger, and a delivery channel leading to the housing outlet. The biasing mechanism biases the piston pump casing towards the housing outlet. The trigger mechanism has a catch member and a restraining member movable by a manually actuatable trigger from a cocked to a triggered configuration. The cocked restraining member engages the catch member to prevent movement and fluid discharge. A triggered restraining member disengages from the catch member for movement of the casing towards the housing outlet to discharge fluid from housing outlet.

Abstract: The present invention provides a dispensing apparatus for delivering metered doses of product from a pressurised dispensing container comprising: a housing comprising a body portion and a removable mouthpiece, the body portion containing a dose counting mechanism and a sleeve; the body portion comprising an aperture through which said pressurised dispensing container can pass to be received in the sleeve but through which the sleeve is unable to pass such that the sleeve is retained within the body portion; the sleeve being located in the body portion such that an upper end of said pressurised dispensing container when received in the sleeve is accessible to allow actuation of said pressurised dispensing container; the apparatus comprising means for retaining said pressurised dispensing container in the body portion.
