Patent ID: 7163013

Claim:
An apparatus for the nasal or oral delivery of a medicament to a patient, comprising: (a) a sealed flexible container including the medicament and a gaseous propellant for the medicament; and (b) a delivery device, including: (i) a main body part which, at least in use, holds the sealed flexible container, the main body part including a nozzle by which the medicament is delivered to the patient; and (ii) a compressive part which, when actuated in use, compresses the sealed flexible container, thereby pressurizing the gaseous propellant within the container, which pressurization of the gaseous propellant causes to sealed flexible container to be ruptured and the propellant to expel the medicament from the apparatus, thereby delivering the medicament to the patient; wherein the main body part includes a protrusion adjacent to the nozzle, to assist the rupturing of the sealed flexible container, the protrusion being arranged such that the compression of the sealed flexible container by the compressive part causes the sealed flexible container to be driven against the protrusion and thereby to be ruptured where it meets the protrusion.
