に使用できないという問題点もある。However, aluminum also has the following problems. That is, since aluminum is relatively soft, there is a problem that the surface is easily scratched. For home use, this problem has been addressed by coating the aluminum with a non-stick layer such as polytetrafluoroethylene or with an enamel layer. However, since aluminum is soft as a support, the life of these coatings is limited, and the problem that the surface is easily scratched has not been completely solved. In particular, when used in a cooking container such as a pan or a frying pan, the bottom surface of the cooking container that comes into contact with a cooking stove such as a gas range, an electric range, a cooking table, and a desk is particularly likely to be scratched. There is a problem. Further, in recent years, electromagnetic cooking devices that are not easily contaminated and do not use a direct fire have become widely used as cooking heating appliances, but aluminum is not a magnetic material, so a cooking container made of aluminum is There is also a problem that it cannot be used for an electromagnetic cooker.

The aluminum projection 4 protruding from the bottom surface 1a is crushed. As shown in FIG. 6, a portion of the projection 4 that protrudes from the punch material 2a forms a closing portion 5 that spreads over the hole 3a and closes it. Since the closed portion 5 is pressed, it has substantially the same height as the surface of the punch material 2a,
A thin layer covering the punch material 2a is formed around the. For this reason, the punch material 2a is fixed to the container body 1 by the closing portions 5 formed for each of the plurality of holes 3a.
The second pressing step may be performed using the press used in the container body forming step and the first pressing step. afterwards,
Container body 1 in which punch material 2a is embedded through the above steps
Is performed, the outer enamel finishing step, the inner surface processing step, and the bottom finishing step are performed to complete the method of manufacturing the cooking container according to the present embodiment. Also, curling,
Necking, boring, polishing, surface processing for covering with an enamel or fluorocarbon resin layer, or the like may be performed.
