<P>PROBLEM TO BE SOLVED: To provide a middle plug and a cap of a liquid spouting vessel in which no slit in the longitudinal direction or the circumferential direction is formed in a fitting cylindrical part of the middle plug, a fitting projecting bar of an outer cylinder is formed over the entire circumference of the middle plug, a notched part is formed from the outer side of the fitting cylindrical part, a breakable weakened line is formed along an inner circumferential surface of the outer cylinder so as to easily pull out the middle plug, a knob part is formed large to be easily knobbed, and disposed in the circumference of the outer cylinder and covered by the cap. <P>SOLUTION: In the liquid spouting vessel comprising the middle plug which is punch-fitted to a mouth cylindrical part of the vessel and provided with the fitting cylindrical part comprising an outer cylinder, an inner cylinder and a shoulder wall and a spouting cylinder and the cap, the fitting projecting bar is provided on a lower end of the inner circumference of the outer cylinder over the entire circumference, the notched part is formed from the outer side on the outer circumference of the outer cylinder, the weakened line is formed along the inner circumferential surface by the notched part, and a cut groove extending in the circumferential direction is formed on a lower side of the shoulder wall as a starting point corresponding to an end part of the weakened line along the inner circumferential surface of the outer cylinder. <P>COPYRIGHT: (C)2003,JPO |
