[Problem to be Solved]
There are provided: a thermal history change type indicator by which the degree of reconstitution with hot water of instant cup noodles can be easily visually recognized in conjunction with the temperature in a container; and a set of a thermal history change type indicator and instant cup noodles comprising the thermal history change type indicator and instant cup noodles.
[Solution]
The thermal history change type indicator comprises: a thermally meltable material layer containing a thermally meltable material; a permeation layer, wherein the permeation layer becomes transparent or translucent when the thermally meltable material melts and permeates the permeation layer; a thermally meltable material permeation-inhibiting layer for inhibiting the permeation of the thermally meltable material into the permeation layer, wherein the thermally meltable material permeation-inhibiting layer is arranged between the thermally meltable material layer and the permeation layer; and a protective layer, wherein the thermally meltable material layer, the permeation layer, and the thermally meltable material permeation-inhibiting layer are layered, and the permeation layer side of the layered product is covered with the protective layer. The set of a thermal history change type indicator and instant cup noodles comprises the thermal history change type indicator and instant cup noodles.
[有待解决的问题]
本发明提供了:一种热历史变化类型指示器,通过该指示器可以结合容器中的温度很容易地直观识别方便杯面与热水的混合程度;以及一套热历史变化类型指示器和方便杯面,包括热历史变化类型指示器和方便杯面。
[解决方案]
热历史变化类型指示器包括热熔材料层,包含热熔材料; 渗透层,其中当热熔材料熔化并渗透到渗透层时,渗透层变得透明或半透明; 热熔材料渗透抑制层,用于抑制热熔材料渗透到渗透层,其中热熔材料渗透抑制层布置在热熔材料层和渗透层之间;保护层,其中热熔材料层、渗透层和热熔材料防渗层是分层的,分层产品的渗透层一侧覆盖有保护层。热历史变化类型指示器和方便杯面的组合包括热历史变化类型指示器和方便杯面。
