Abstract: A degassing device takes the form of lid or cap-like structure which is formed with notches/flexible members that engage the container being de-gassed and facilitate its application to various size containers. A through-hole into which a nozzle of the aerosol container is disposed, is provided with one or more shaped ribs which project out into the opening and engage the tip of the nozzle after it has passed a given distance through the through-hole. As the device continues to be pressed down into place on the container, the nozzle is depressed, the valve mechanism associated therewith is opened, and the remaining gas/fluid, which remains in the container is allowed to vent. A deflecting member is provided at the downstream end of the through-hole and arranged in the path of the venting gas/fluid to deflect fluid flow.

Abstract: A valve assembling and checking method includes the steps of: using air pressure from a nozzle 50 to press a spring 4 against the inner wall of a valve hole 2 to hold the same in a vertical position; moving the spool 3 immediately above the valve hole and allowing the spool to fall from a spool holding means 30, and repeating clamping and unclamping actions to adjust the location of the spool so that the spool is correctly received in the valve hole 2.
