ABSTRACT:
The invention discloses a cap made of plastic material for containers holding liquids, which includes an essentially cylindrical main body and an element for dispensing the liquid. The dispensing element has an essentially round, flat upper part, hinged into the main body and a lower part in the shape of a socle having a partially cylindrical base surface which slides on a corresponding concave surface belonging to a main body. The contact between the cylindrical surface of the base and the concave surface of the main body insures the tightness. Moreover, around the opening of the concave surface of the cylindrical body there is a ring-shaped projection acting as a seal when the dispenser is in its open position. When the dispenser is closed, the ring-shaped projection matches a corresponding round indentation which is found in the base, so as to insure the tightness between the dispenser and the body of the cap, regardless of the position of the container.
