PLASTIC CAP FOR SPRAYING BY AEROSOL CAN

摘要

PURPOSE:To enable easy absorption of the variance in the height of a valve stem by constructing specifically a lever provided across the upper central part of a cap. CONSTITUTION:When a user exerts pressure on the top of the valve of an aerosol can be depressing a lever 2, the point of application of a cylindrical curved surface 3 on the bottom surface of the lever 2 that contacts with the valve top moves upward on the curved circumference as the force point at which the lever 2 is depressed descends. Namely, the lowermost end of the curved surface 3 is nearer the fulcrum 7 side than the central point of the valve top in the position where the level 2 is not depressed. The lowermost end of the surface 3 is on the side of an elephant nose-shaped sagging body 9 in the lowermost position of the lever 2 and the fluctuation in the height of a valve stem is absorbed during this time.
