The key point of the structural design is that the inner diameter of an inner cup opening of the enamel inner shell is provided with an outward horn mouth, the turned edge of the inner edge opening of the enamel outer shell is larger than the turned edge of the outer edge opening of the enamel inner shell, and the bottom of the enamel outer shell is provided with an upward convex bottom groove.
The center of the bottom groove at the bottom of the enamel shell body is provided with a small exhaust hole which is blocked by silica gel.
And a small exhaust hole and silica gel blockage are omitted in the center of the bottom groove at the bottom of the enamel outer shell.
And a foaming agent filled through a small exhaust hole is arranged in a hollow layer between the outer diameter of the enamel inner shell and the inner diameter of the enamel outer shell.
The enamel tableware is made by using cold rolled steel plate as blank material, and the product is formed by combining inner and outer layers of blanks, and the inner layer and outer layer of blanks are combined by using edge curling, except that the edge curling position is overlapped, other positions have certain space difference, and the bottom of the outer layer iron forward is left with small exhaust holes.
The enamel tableware is an enamel bowl, an enamel plate or an enamel cup.
The utility model has reasonable and simple structural design, convenient and feasible production and manufacture, and particularly, the edge openings of the inner layer and the outer layer are simultaneously sealed and butted for forming during the edge curling operation, thereby having good anti-collision, anti-scalding and heat preservation effects; it is suitable for being used as a double-layer hollow enamel tableware and the improvement of the production process of the similar products.
