Being the residual life indicator for the residual life indicator null

摘要

Being the residual life indicator for the non permanence consumer product, following to specified function, as with fluctuation of temperature shown the aforementioned quality to the material and this material which show fluctuation possible quality, we possess with the operation expedient which operates this material and the indicator expedient which is connected to the combination of the aforementioned material/operation expedient, we indicate the residual life this indicator expedient for end day of the aforementioned product, the indicator. According to this invention, as for the aforementioned material having possessed the viscosity which fluctuates as a function of temperature, the pipe of specified section (2,212; 4,134) inside the fluid which flows (102; 114) the device which as for the aforementioned operation expedient the aforementioned fluid (102,114) can be, impress fixed pressure essentially (311,601,411,701; 313,203,113,204) we possess, the fluid flow aforementioned is connected the aforementioned indicator expedient (701,413).
