    • PROBLEM TO BE SOLVED: To provide, for compressed gas packaging, valve equipment which is so structured that gas does not leak and a cleaning process takes place after a product fetching process. SOLUTION: This equipment includes a valve body 3, valve housing 6, a spring 7 and a valve head 8; and the valve body includes a hollow shaft 4 and a shaft body 5 combined to the shaft 4. In the inside of the valve housing whose compressed gas packaging side is open stores the shaft body having the shaft protruding from the valve housing, and the shaft body is positioned on the spring and is supported by the spring in the valve housing. The valve head has an opening 9, closes the compressed gas package 1 and the shaft extends through the opening. The valve housing is sealed off from the valve head by a packing surrounding the shaft. The shaft has a side face opening 11, and the opening 11 is closed by another packing in a condition where the spring is not pressed. Between the two packings, an essentially gas tight space 12 is formed, and this space communicates with an area with a propellant through a passing step and two gas channels 19, 20 on the valve housing.

    • PROBLEM TO BE SOLVED: To provide a compressed gas container from which a foam product in predetermined distribution quantities can be taken out repeatedly. SOLUTION: A cap 2 is provided to take out a foam product in distribution quantities by means of a valve 3, and a mixing device 4 is provided to turn at least one kind of liquid product into at least one foam cord-like form. The device 4 has at least one hollow cylindrical chamber 6, wherein a pressure piston 7 made movable upward from a lower position by a propelling agent so that the product 5 is mixed through at least one mixing passage 8 provided in a foam passage 9 is provided. The valve 3 is a two-passage valve and a first passage 10 is provided to prepare an expandable liquid mixture (work substance/propelling gas) 12, and a second passage 11 is provided to guide a liquid gas 13 from a propelling gas container 13.1, which passage 11 is serviceable to move the piston 7, and a pressure regulating device 14 is provided to cause the gaseous propelling gas to flow out and the device 14 acts when the valve 3 is out of operation.
