People who are busy outside work often miss the time to eat with their families. Usually the family will leave a meal for family members who can't get back home in time, but the food left will slowly cool down, and reheating will bother the food and lose the original taste. We designed this insulated lid to store the heat from cooking to keep the food warm. For the late returning person, this can be insulated, not only the temperature of the food, but also the warmth of a home.
