[0013] Preferably, the bottom supports correspond to the card slots one by one and are evenly distributed at equal angles on the bottom of the foldable cup body. At the same time, the card slots are engaged and positioned with the lower end of the straight cylindrical winding bracket.

[0014] Preferably, the bottom support is made of metal, wherein the bottom support is rotatably connected to the folding cup body, and the upper end of the bottom support is movably connected to the outer wall groove of the straight cylindrical winding bracket.

[0015] Preferably, the straight cylindrical winding brackets are distributed in a triangular shape in the folding cup body, and movable partitions are movably installed between adjacent winding brackets to separate the internal space of the folding cup body.

[0016] The present invention also provides a production process for a scalding-proof paper bowl that can be heated in an electromagnetic cooker, and the process is as follows:

[0017] Step 1: First, a folding ring is made through a folding process, and the middle structure of the folding cup body is formed by stably combining the folding ring and the connecting ring through hot pressing.
