As shown in fig. 1 and 2, in the present embodiment, the groove 30 has an arcuate cross-section. The above structure makes the pot teeth 20 have high strength. It should be noted that the "cross section" refers to a plane formed by cutting the groove 30 parallel to the upper surface of the pot tooth 20, and the plane is not actually a solid plane. The "arcuate" refers to a pattern of chords and their corresponding arcs.

As shown in fig. 1, in the first embodiment, the heat-insulating cover body 10 includes a cover body side wall 11 and a flange 12 disposed at an upper edge of the cover body side wall 11 and extending outward, an opening is formed at the upper edge of the cover body side wall 11, a pot tooth 20 is disposed on the flange 12, the groove 30 has an arc-shaped wall 31 recessed inward, a radius of the arc-shaped wall 31 is greater than or equal to a thickness of the pot tooth 20, and is less than or equal to a distance between an outer edge of the pot tooth 20 and an outer edge of the flange 12. Specifically, if the radius of the arc-shaped wall 31 is smaller than the thickness of the pot teeth 20, the strength of the pot teeth 20 is less affected, and the pot teeth may be easily deformed after long-term use, resulting in unsmooth opening and closing of the lid. And it is inconvenient to process if the radius of the arc-shaped wall 31 is greater than the distance between the outer edge of the boiler teeth 20 and the outer edge of the flange 12.
