PROBLEM TO BE SOLVED: To avoid separation of a valve body from a jetting valve seat when it is opened, and to prevent the valve body from being lost by a constitution wherein a plurality of elastic reverse thorns are projected to oblique upper outward from the lower end of a small rod-like part hung from the underside of a sphere to make a first valve body and gap for opening a jetting valve hole is formed between the upper end of a reverse thorns and the underside of the sphere. SOLUTION: In a liq. pouring container 51 which pours liq. from a nozzle 59 through a suction valve 61 and a jetting valve 62, a first valve body 1 being a valve body for a jetting valve is formed by hanging down a small rod-like 3 from the central part of the underside of a sphere 2 and projecting a plurality of elastic reverse thorns 4 to oblique upper outward from the lower end of the small rid-like part 3. In addition, the small rod-like part 3 is formed in such a way that it has a smaller outer diameter than the jetting valve hole 64 of the liq. pouring container 51 and an imaginary circle formed by the upper ends of the reverse thorns 4 is formed to be larger outer diameter than the jetting valve hole 64 and, between the upper ends of the reverse thorns 4 and the underside of the spherical body 2, a gap for releasing the jetting valve hole is provided. To mount this first valve body 1 on the upper part of a stem 57 of the liq. pouring container 51, it is performed by inserting the small rod-like part 3 with the reverse thorns 4 into the jetting valve hole 64. |
