The concept of this children's thermos bowl comes from a planet in a child's fantasy world. It is illusory and full of innocence. The concave texture on the lid simulates the natural texture of the planet's surface, while the air pressure valve in the middle is the core of the "planet.

The bowl body is divided into inner and outer bowls, which can inject hot water into the outer bowl to provide longer heat preservation time for delicious food.

The "doughnut" handle, which is divided in half and half, allows users to grasp it better. At the same time, they can easily unscrew the fixing ring and take out the inner container by pushing it in opposite directions with their index finger and thumb. It avoids the dilemma that the user cannot easily unscrew because the diameter of the bowl body is too large or the negative air pressure formed due to the injection of hot water.
