Fluid Safety Device

Abstract

Devices for labeling and discharging a contaminated fluid, and discharging a contaminant to prevent a contaminated fluid from being used. In an embodiment, a discharging device includes a wax sealing an aperture at the bottom of a water bottle. The wax melts at a high temperature which may cause the water in the bottle contaminated, releasing the water from the water bottle. In another embodiment, a discharging device including an aperture in a DEF tank and a seal material sealing the aperture is used to discharge mistakenly filled contaminant, which dissolves the seal material. In another embodiment, a labeling device including an ink sealed in a wax wrapper is disclosed. The wax wrapper melts at high temperature, releasing the ink and labeling a fluid as problematic. By using a conductive ink with a non-conductive fluid, the labeling device can also be used for detecting and recording high temperature events.

1 . A fluid container for storing a fluid, comprising:
 a container body for holding said fluid; and   an marking device for making changes in said fluid when an event happens including a solute material that is soluble in said fluid sealed in a wrapping material which is insoluble in said fluid, wherein said marking device is fluidly connected to said container body and said wrapping material in said marking device melts when a temperature, in which said fluid container is exposed, is above a melting temperature of said wrapping material, releasing said solute material into said fluid.   
     
     
         2 . The fluid container of  claim 1 , wherein said solute material includes an ink with a color different from said fluid. 
     
     
         3 . The fluid container of  claim 1 , wherein said marking device is positioned in said fluid. 
     
     
         4 . The fluid container of  claim 1 , further comprising a cap through which said fluid is filled into said fluid container, wherein said marking device is positioned on an inner surface of said cap. 
     
     
         5 . The fluid container of  claim 1 , wherein said wrapping material includes a wax. 
     
     
         6 . The fluid container of  claim 1 , wherein said solute material has a conductivity different from said fluid. 
     
     
         7 . The fluid container of  claim 6 , further includes a conductivity measurement device generating a sensing signal indicative of said conductivity in said fluid. 
     
     
         8 . The fluid container of  claim 7 , wherein said conductivity measurement device further includes a controller configured to generate an alarm signal when said sensing signal indicates that said conductivity in said fluid is out of a predetermined range. 
     
     
         9 . 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.   
     
     
         10 . The fluid container of  claim 9 , wherein said first sealing piece has polystyrene incorporated. 
     
     
         11 . The fluid container of  claim 10 , wherein said working fluid is a urea solution and said contaminant includes gasoline. 
     
     
         12 . The fluid container of  claim 9 , wherein said working fluid is a urea solution and said dissolvent is diesel. 
     
     
         13 . The fluid container of  claim 9 , further comprising a refill passage through which said working fluid is refilled into said container body and a bore in said fluid safety device with a float positioned inside, wherein said first sealing piece is fluidly connected to said bore. 
     
     
         14 . The fluid container of  claim 13 , wherein said float includes an upper part which has a density lower than said contaminant, a lower part which has a density higher than said contaminant and lower than said working fluid, and said dissolvent hold in between said upper part and said lower part. 
     
     
         15 . The fluid container of  claim 14 , wherein said dissolvent is gasoline. 
     
     
         16 . The fluid container of  claim 14 , wherein said bore is separated from said refill passage by a second sealing piece, which loses its sealing function in said dissolvent. 
     
     
         17 . The fluid container of  claim 14 , wherein said bore is separated from said container body by a third sealing piece, which loses its sealing function in said dissolvent. 
     
     
         18 . The fluid container of  claim 14 , wherein said bore is shorter in length than said refill passage. 
     
     
         19 . 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.   
     
     
         20 . The fluid container of  claim 19 , wherein said working fluid is a drinking water and said sealing piece includes a wax.
