Title:
PRECISE CRITICAL TEMPERATURE INDICATOR AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/074529
Kind Code:
A1
Abstract:
According to a precise critical temperature indicator and a control method thereof of the present invention, the precise critical temperature indicator comprises as one body: a blocking boundary layer which is positioned between a spreading material member including an operation button and spreading medium members including a spreadable area for a spreading material; and a temperature sensor which is controlled and operated as the spreading material passes through the blocking boundary layer and contacts the spreading medium member according to a user's pressing of the operation button. As a result, operation of the temperature sensor is easily controlled using the operation button. Also, the precise critical temperature indicator does not require a process of cooling a product down to below a critical temperature before using the product, due to the hermetic sealing of the spreading material member. Additionally, mass production can be realized by combining a spreading material member sheet including a plurality of spreading material members and a spreading medium member sheet including the spreading medium members which includes a plurality of spreadable areas for the spreading material.
