To measure an objective value of Ga by accurately taking out a desired amount of Ga when Ga being housed in a container is taken out from the container, and at the same time, recover Ga sticking to the internal wall of the container by completely taking out.

This housing container 10 is equipped with an outlet 21 in order to take out liquefied Ga 5 from the bottom of a container main body 1, and an air inlet 31 in order to take in air from the top of the container main body 1. For such a housing container 10, a screw type cap 32 or a cock is provided at the air inlet 31. When Ga 5 is taken out, by taking out Ga 5 while taking in air from the air inlet 31, air pressures for the outside and the inside of the container become the same, and also, the flowing out amount of the liquefied Ga can be adjusted by the taking-in amount of air.
