Dispensing apparatus with metering chamber and aerosol type dispenser therewith

摘要

A dispensing apparatus and an aerosol type dispenser therewith for discharging contents stored in a metering chamber effectively. The dispensing apparatus is comprised of a cylindrical portion (11a) for providing a circular recess portion (11f) which keeps a part of the contents in the metering chamber and a cylindrical skirt (21c) for providing a detour in the circular recess portion. The cylindrical portion and/or the cylindrical skirt form grooves (11g) so as to make a sectional area for flowing contents smaller. In mode in use, the upstream contents positioned inside the cylindrical skirt take a long way around the circular recess portion at high speed and high pressure, therewith contents settled in the circular recess portion are forced to the passage of the valve stem. <IMAGE>
