Claim:
1. A spuit-type container cap for automatic filling and fixed-amount dispensing, comprising a container cap ( 50 ) which is compressed by being screw-coupled to a container ( 1 ) in which cosmetics are accommodated and an opening ( 1 a ) is formed in the upper side thereof, and then is filled with the content of the container ( 1 ) when the container cap ( 50 ) is decoupled from the container ( 1 ) wherein the container cap ( a first cylindrical member ( 51 ) which is a cylindrical member having opened upper and lower parts and is screw-coupled to the container ( 1 ) through the lower side thereof; a second cylindrical member ( 53 ) which is a cylindrical member having an opened upper surface and has, in the center of the lower surface thereof, a support ( 53 a ) that is protruded to the lower part such that a spuit pipe ( 52 ) accommodated in the container ( 1 ) can be inserted from the lower side, wherein the second cylindrical member ( 53 ) is provided with a pair of guide protrusions ( 53 b ) which are vertically formed on both sides of an outer surface thereof so as to vertically move by being inserted into a pair of guide grooves ( 51 a ) vertically formed on an inner surface of the first cylindrical member ( 51 ) when the container ( 1 ) is screw-coupled to the first cylindrical member ( 51 ); a cylindrical accordion member ( 54 ) having a lower inner surface in which a cylindrical protrusion ( 53 c ) protruded in a cylindrical form from the upper side of the lower surface of the second cylindrical member ( 53 ) is mounted; a circular plate-shaped member ( 55 ) which has a lower side protrusion ( 55 a ) mounted on an upper inner surface of the cylindrical accordion member ( 54 ), and of which a lower end of an outer surface thereof is placed on the upper side of the first cylindrical member ( 51 ); a rubber valve ( 56 ) which is inserted into a central hole ( 55 b ) of the circular plate-shaped member ( 55 ), and which is operated in order to introduce upper air through a plurality of slits ( 55 c ) radially formed on the outer side of the central hole ( 55 b ) and to prevent lower air from being discharged; a dome-shaped rubber button ( 57 ) which has a convex upper surface and has an air inlet hole ( 57 a ) in a central part thereof that is inserted into the outer side of the upper surface of the circular plate-shaped member ( 55 ); and a cylindrical cover member ( 58 ) which has a locking end ( 58 a ) on an inner surface of the upper part thereof such that a stopping end ( 58 a ) is locked in a step ( 57 b ) formed on the outer surface of the rubber button ( 57 ), and which simultaneously covers the outer surfaces of the circular plate-shaped member ( 55 ) and the first cylindrical member ( 51 ).
