Abstract
本发明提供了一种氧指示型脱氧剂及其制造方法，其中，氧指示型脱氧剂包括容纳脱氧剂件的透气内膜和设置氧指示件的打孔外膜，打孔外膜包括包覆透气内膜的本体部和由本体部向外延伸形成并容纳氧指示件的指示件引入部，指示件引入部包括纵向封边区和介于纵向封边区和本体部之间并覆盖氧指示件的透明区。本发明将脱氧剂件和氧指示件分开装入，置于指示件引入部中的氧指示件，因为外膜打孔，其透气度大，透气性很稳定，故氧指示件变色快，能准确、直接地对脱氧剂的脱氧情况做出反应，脱氧剂件被透气内膜所包裹，其孔径较小，不会出现漏粉现象。同时，指示件引入部覆盖氧指示件的区域为透明区，故通过氧指示型脱氧剂两侧的透明区可于双面观察氧指示件的变色情况。
The present invention provides an oxygen-indicating deoxidizer and a method for manufacturing the same. The oxygen-indicating deoxidizer comprises a breathable inner membrane for housing a deoxidizer element and a perforated outer membrane for housing the oxygen indicator element. The perforated outer membrane comprises a main body covering the breathable inner membrane and an indicator inlet extending outward from the main body to accommodate the oxygen indicator element. The indicator inlet comprises a longitudinally sealed edge region and a transparent region between the longitudinally sealed edge region and the main body and covering the oxygen indicator element. In the present invention, the deoxidizer element and the oxygen indicator element are separately packaged. The oxygen indicator element, housed in the indicator inlet, has high and stable air permeability due to the perforated outer membrane. Therefore, the oxygen indicator changes color quickly and accurately and directly reflects the deoxidation status of the deoxidizer element. The deoxidizer element is encased in the breathable inner membrane, which has a small pore size and prevents powder leakage. Furthermore, the area of the indicator inlet covering the oxygen indicator element is a transparent region, so the color change of the oxygen indicator element can be observed from both sides of the oxygen-indicating deoxidizer through the transparent regions on both sides.
