A precise critical temperature indicator is applied to small products requiring refrigeration or freezing to control the operation of a temperature sensor built into an integrated structure of a single body. A method for manufacturing said precise critical temperature indicator, wherein a plurality of development medium members and a plurality of development material members are opposed to each other, and blocking members are interposed therebetween to support the development medium members and the development material members separately from each other, the development medium members are provided with paths for moving development materials, or paths for movement of development materials can be shortened to adjust speed, and an indication unit is arranged to indicate the state of the development materials at an end or central portion of the development medium when the development materials are exposed to a critical temperature for a predetermined time period.

This is a 35 U.S.C. §371 application of, and claims priority to, International Application No. PCT/KR2009/006088, which was filed on Oct. 21, 2009, and which claims priority to Korean Patent Application No. 10-2008-0104758, which was filed on Oct. 24, 2008, and No. 10-2009-0065770, which was filed on Jul. 20, 2009 and the teachings of all the applications are incorporated herein by reference.
The present invention relates to a critical temperature indicator, in particular to a precise critical temperature indicator to be easily adapted to relatively smaller storing products necessary for refrigeration or freezing and to control a temperature sensor built into an integrated structure of a single unit therein and a manufacturing method therefor.
There has been a critical temperature indicator of a typical prior art that can be obtained as a commercial name “MONITOR MARK™” of 3M.
FIG. 1 is an exploded perspective view illustrating one example of a prior art in detail.
FIG. 2 is an exploded perspective view illustrating a critical temperature indicator provided with a temperature sensor in detail according to one embodiment of the invention.
FIG. 3 is a plane perspective view illustrating the assembly state of a critical temperature indicator provided with a temperature sensor according to one embodiment of the invention.

The invention will be explained in detail with reference to accompanying drawings, which has a configuration integrated into a single body.
According to the invention, as shown in FIGS. 2 and 3 a precise critical temperature indicator 100 includes a single substrate 101 that is a single flatness plate. The single substrate 101 includes 3 portions foldable to each another. Among them a first portion 102 includes an indication window 103 formed adjacent to one edge or at a predetermined position of the center and a development medium member 104 having a predetermined area which is positioned in a side by side to the first portion 102. A liposoluble dye 107 is applied adjacent to one edge of a first protection film 106.
