[0002] The paper bowl heated by the induction cooker is a container for storing materials to be heated when the induction cooker is working. It is convenient for placing materials and can also store materials when they are not in use. Different from ordinary disposable paper bowls, this special paper bowl is a container that can be reused multiple times. In addition to being used for heating, it can also be used to store fruits and vegetables, and can also be used to heat ready-to-eat hydraulic or semi-liquid materials.

[0003] The paper bowls used for existing induction cookers are generally directly used for heating by adding components such as inner coatings and metal pads. However, the use of the paper bowl as a whole has a strong focus on space occupation and the application of food materials. In particular, when it is used for take-out or as a partition in the internal space, its overall complete structure is easily deformed and damaged when used for take-out. At the same time, when different types of food materials need to be heated, multiple repeated heating is required. The internal space of the paper bowl cannot be quickly separated, resulting in changes in the space inside the paper bowl so that different types of food materials can be heated simultaneously and simultaneously. It can only be used for boiling and water bathing of fluid food materials, and cannot be used for steaming and instant eating in outdoor environments.
