<P>PROBLEM TO BE SOLVED: To prevent a content liquid from being accidentally discharged during transport, or from being fraudulently unsealed in a liquid pouring-out container equipped with a piston vertically movable type liquid pouring-out device. <P>SOLUTION: A cylinder 3 is vertically provided and fixed in a manner to penetrate a lid body 2 which is screwed with a container main body mouth part 1a. At the same time, a suction valve 4 is provided on the bottom section of the cylinder to form a pouring out pump main body. A cylindrical body 7 on the outer peripheral section of the lower end of which, a piston 5 is peripherally provided, and at the same time, on the inner peripheral section of which, a discharging valve 6 is provided is slidably fitted in the cylinder. The upper end part of the cylindrical body is projected upward from the cylinder upper end opening part to form a stem 8. A jetting head 9 is fitted on the upper end part of the stem to form this liquid pouring out device which can reciprocate by a pressing operation. On the outer peripheral surface of the stem upper end, a cylindrical stopper 11 which prevents the jetting head from descending is formed in a manner to be excisable. In addition, a discharging valve is formed in such a manner that a ball valve is detachably joined closely to a valve seat cylindrical section. At the same time, the suction valve 4 is formed of a rod-shape valve member 4a which can push up the discharging valve 6 to constitute the liquid pouring-out device. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
