Polyurethane aerosol can emptier

摘要

The cap nut (5) on the threaded connection (3) positively grasps a collar (7) of the valve plate (8), the nut being recessed (9,10) in its sidewalls to match the height and breadth of the collar and valve (12), and with recess open to the endface of the nut. At the end associated with the cap nut, the connection rests via its shoulder (13) on a step provided on the inside (14) of the nut and the free end of the interior is ring-grooved (15) to positively accept the collar. Once the cap nut has been slid in from the side via recesses onto the collar, the entire emptying device (1) is thus placed on the valve plate and so on the can lid. At this stage, the nut is drawn down the connection until this places the valve in its open setting and thus into the connection bore (11).
