ABSTRACT:
The specification describes a valve assembly for and a method of manufacturing a pressurized spraying container. The body of the valve is provided with an external tubular extension or sleeve in which is temporarily located the valve member. The sleeve is used to guide fluid under pressure into the container and may also be used during the blow molding of the container. When the container is filled, the valve member is forced through the sleeve into engagement with its valve seat, where it is retained by an already positioned spring, and the sleeve is detached.
