How does it work?
For best results, before use, pre-fill for about 3 minutes, using hot water for hot food or cold water for chilled food (DO NOT overfill your flask). Leave sufficient space in the neck to fit the lid. The top of Thermo-pot is larger than most liquid flasks, therefore you should heat your food to the maximum temperature possible in order to have optimal heat retention. Lid must be hand-tightened but without extra force as the extreme temperatures will make it more difficult to open your food flask.
