PURPOSE: To safely contain a harmful liquid and use it by closing one end of a cylinder whose both ends are opened, with an end cap and providing a piston, a valve unit closing the other end, a closing element of the valve, and a device preventing approach to the valve element. CONSTITUTION: In the package 10, a piston 24 is pushed into the opening end 26 of a cylinder 16 through a ring 22 and a block 36 is arranged toward the rear face of the piston 24, and the end cap 28 is pushed in from the end of the cylinder 16. A liquid is charged from the neck 14 and an assembled unit 38 is firmly fixed to the neck 14, and the cap 28 is tightly fitted thereto. A spike 94 os a disposable container 70 is exposed and fitted to the body. Pressure water is connected to the inlet 74, the valve 76 is opened and water flows in the body 72 and strikes the head 98 of the valve 96. The contents is squeezed out into the water stream by the hydraulic pressure acting on the exposed face of the piston 24 through the center hole 92. The closing element 96 of the valve and the block 36 prevent water leakage and absorb it. In this way, harmful liquid can be safely contained and easily taken out and used. |
