Patent ID: 8721617

Claim:
A liquid component collecting device comprising: a flexible cylindrical liquid component storage container having a first opening and a second opening at one end; a rigid cylindrical first housing container for housing the liquid component storage container therein and having an opening at one end; a pressure regulating space formed between an outer side of the flexible liquid component storage container and an inner side of the rigid first housing container, the pressure regulating space being hermetically sealed from an internal space of the liquid component storage container and from an external environment of the liquid component collecting device; and a first cap configured to hermetically seal the internal space of the liquid component storage container and the pressure regulating space from each other and from the external environment, the first cap comprising: a liquid component inlet channel engaged with the first opening of the liquid component storage container and configured to allow passage of a liquid component therethrough, a first communication channel engaged with the second opening of the liquid component storage container and configured to communicate with the internal space of the liquid component storage container, and a second communication channel engaged with the opening of the rigid first housing container and configured to communicate with the pressure regulating space so as to regulate an internal pressure of the pressure regulating space between a high pressure state, wherein the flexible liquid component storage container is deformed as if being crushed, and a low pressure state, wherein the pressure regulating space is configured for restoring of the deformed liquid component storage container into its original condition, thereby drawing the liquid component through the liquid component inlet channel.
