Title: POWDER DISPENSER
Abstract:
The invention relates to a dispenser for delivering powder to the nose, comprising, a body, a powder container, an outlet and an actuator. The body defines a piston chamber including a conduit providing a fluid pathway to a container chamber, which comprises the powder container. The powder container defines an internal volume within which a predetermined dose of powder is located, an inlet aperture sealed by an inlet seal, and an outlet aperture sealed by an outlet seal. The powder container is arranged in a fluid flow path between the conduit and the outlet such that fluid flow from the conduit to the outlet is substantially prevented by the inlet and outlet seals of the powder container. The actuator includes a piston and a piercer and is coupled to the body such that it is movable relative to the body from a first position to a second position.
