Container for high purity liquid chemicals

摘要

A container does not cause any quality deterioration of high purity chemicals (4) included therein during the storage and transportation thereof and is not easily broken. The container also permits easy and safe discharge of the high purity chemical. The container for a high purity chemical comprises a flexible internal container (2) formed from a polyolefinic high purity resin and a gas-tight, self-supporting external container (3), which accommodates the internal container, wherein these internal and external containers are joined together in such a manner that the space formed between these two containers are arbitrary closed and opened so as to ensure the communication with the outside, a liquid-discharge pipe (16) provided with a check valve (19) connected to the pipe midway therein is gas-tightly inserted into the internal container down to the bottom thereof and a connector (12) connected to a pressure source (11) is fitted to the external container. <IMAGE>
