When the "insulator layer" (a phase change material or PCM) is between phases, it can absorb or emit energy without changing temperature. The drink on the other hand will change temperature as it looses energy. The drink will lose energy through the lid, leading to a small temperature gradient between the PCM and the drink. This gradient should allow energy to flow back from the PCM into the drink. |
