PURPOSE:To make it possible to use a pressure non-resistant inexpensive container in the pressure feed of chemicals, by feeding chemicals under pressure by using a pressure resistant outer container receiving a container storing liquid chemicals, a gas introducing pipe, a chemicals transfer pipe and a siphon tube. CONSTITUTION:A pressure resistant outer container 6 having a lid 22 is supported on the bottom part support of a stand 12 and a chemicals container 18 and the weighing stand 26 weighing the wt. of said container 18 are arranged in the outer container 16. A gas introducing pipe 30 introducing compressed gas and a chemicals transfer pipe 32A are connected to the outside of the lid 22 in a sealed state. The gas introducing pipe 30 is communicated with a gas supply source 34 while the chemicals transfer pipe 32A is communicated with a chemicals use area 36 and further communicated with the transfer pipe 32B in the pressure resistant outer container 16 and the leading end thereof is connected to the siphon tube 38 inserted in the chemicals container 18. In this constitution, when compressed gas is introduced into the pressure resistant outer container, the chemicals of the chemicals container are fed to the outside through the chemicals transfer pipe under pressure. At this time, the inner and outer gas pressures of the chemicals container are identical. |
