難点があった。As shown in FIG. 2, the conventional liquid raw material vaporization container uses a liquid raw material 2 having a low specific heat due to poor heat conduction because the outer wall 1 is made of an integral metal. When the gas is blown from the blow-in pipe 3 and the vaporized liquid raw material is taken out from the gas take-out pipe 4, a temperature difference occurs between the liquid raw material liquid portion 2a and the portion 2b above the liquid surface inside. As a result, there is a problem that the vaporized liquid condenses again or the concentration of the vaporized gas is not constant.

ものである。SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has two or more ports provided in a closed container, and a pipe that reaches from one of them to the vicinity of the bottom of the closed container. Then, a gas is introduced from the pipe into the liquid raw material filled in the closed container to vaporize the liquid, and in a liquid raw material vaporizing container to be taken out from another port, the wall of the container is formed to have a hollow structure. It is an object of the present invention to provide a liquid material vaporizing container characterized by having a heat pipe structure containing a working liquid.

止できる。According to the present invention, since the heat conduction efficiency of the vessel wall is improved, even if a liquid material having a large specific heat is used, the inside of the container is kept at a uniform temperature regardless of the liquid level in the closed container. Thus, reliquefaction of the vaporized gas and fluctuation of the concentration can be prevented.

A working liquid 14 is sealed in the hollow portion 13a. The liquid used is a substance having a boiling point at the environmental temperature in which the container 10 is installed. The gas introduced from the pipe 11 passes through the width of the liquid material in the container, vaporizes the liquid, and is taken out of the pipe 15 to the outside.

The difference can be reduced. Therefore, reliquefaction of the vaporized gas and fluctuation of the gas concentration can be prevented.
