PURPOSE: To prevent fluid contents in an aerosol valve from leaking by providing a stem packing from between a valve housing and a mountain cap to between a valve stem and an ejecting head.
CONSTITUTION: A stem packing is provided from between a valve housing 3 and a mountain cap 1 and to between a valve stem 4 and a spraying head 15, while the stem packing comprises a horizontal disk and a vertical cylinder. Both inner and outer sides of the vertical cylinder of the stem packing are tightly held between a lower end opening 17 of the spraying head 15 and an outer peripheral face of the valve stem 4 to hold liquid tightness and air tightness at the held part to prevent contents from leaking. The stem packing is made of relatively flexible synthetic resin which us resistant to both acids and alkalis, thereby preventing fluid contents in an aerosol valve from leaking.
