<P>PROBLEM TO BE SOLVED: To mainly aim to overcome drawbacks of an aerosol container for spraying a constant quantity employing a first spring for upwardly urging a stem with a valve and in addition, a second spring for pushing up a cover tube for covering an upper external surface of a head that considerable force is needed in pushing down the head and the finger easily gets tired since both springs need to be pushed down approximately at the same time when spraying a liquid in a container body by pushing down the stem with the valve by pushing down the head. <P>SOLUTION: A lower part of an upper surface closing tube 18 is fitted with an upper external surface of a stem 2. Otherwise, the cover tube 21 is fitted by upwardly urging it by a second spring so that it can be pushed down to the external surface of the upper surface closing tube. A gap for accelerating the descending speed of the cover tube is provided between a lower end surface of a sliding tube 23 when lowering the cover tube with the second spring compressed and an upward step 13 of the upper surface closing tube 18 as a push-down surface for the first spring. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
