Abstract

See full text

A medicament source has a container and a crimped closure. The closure sealingly holds to the container a metered-dose release valve, of which the spout only is visible externally. The container has a neck and a protruding rim at which the crimp locates. The container is of molded polymer and has an outer, perforate sleeve of aluminum, providing mechanical strength for pressure retention. The neck has a relatively thicker wall thickness and the end is domed inwards, both for pressure retention. The polymer is of three layers or laminations. The innermost layer is of polytetrafluoroethylene (PTFE) material to provide an inert layer with which the medicament and its propellant will not react or combine in any way. The middle polymer layer is of nylon material to provide a propellant tight layer, to contain the propellant, whose molecules may be able to pass through the PTFE layer. The outer polymer layer is of polypropylene (PP) to provide both water tightness and mechanical integrity of the container.
