摘要

The cap (1) has a spout (2) manually covered on a concave upper surface of the cap whose shape takes the shape of a sphere (3). The spout is inclined on an angle of 45 degree around a vertical axis permitting closing of a device. The angle is reduced to regulate the flow of fluid and the liquid flows when the spout is in a vertical position. Chamfers are situated at ends of a common orifice of the spout and the sphere. Toric joints (5) are inserted between the sphere and the cap, where the joints are fixed in a groove fabricated on a conical part of the cap.
