Fluid Safety Device

A fluid container for storing a working fluid used in an application system, comprising:

• a container body for holding said working fluid;
• and
• a fluid safety device for preventing a contaminant in said working fluid from damaging said application system including an aperture through which a fluid can be released from said container body, and a first sealing piece, which loses its sealing function in a dissolvent, positioned on said aperture sealing it to prevent said working fluid in said container body from leaking therethrough, wherein said fluid safety device is positioned in said container body with said first sealing piece contacting said contaminant in said working fluid and losing its sealing function for releasing said contaminant from said container body.

A fluid container for storing a working fluid, comprising:

• a container body for holding said working fluid;
• and
• a fluid safety device fluidly connected to said container body including an aperture through which all fluid can be released from said container body, and a sealing piece, which loses its sealing function when a temperature of said working fluid is higher than a damage temperature, positioned on said aperture sealing it to prevent said working fluid in said container body from leaking therethrough, wherein said damage temperature is lower than a contamination temperature above which said working fluid is significantly contaminated by contaminants released from said container body.
