Abstract
A container with functions of temperature indication and thermal storage is provided. The container includes: an inner bottle containing a liquid, a temperature indication and thermal storage material layer disposed on the outer side of the inner bottle and a first polymer layer disposed on the outer side of the temperature indication and thermal storage material layer. The temperature indication and thermal storage material layer comprise a thermal storage material and a thermochromic material. The thermal storage material has phase change for absorbing or releasing thermal energy. The thermochromic material is mixed in the thermal storage material and changes at least two of colors depending on a temperature change. Wherein, the first polymer layer includes a wavelength-selective polymer, and the temperature indication and thermal storage material layer absorbs light passed through the first polymer layer.
