っている。As shown in FIGS. 1 to 3, the mold 1 is formed in a circular shape in plan view and has a female mold 3 having a concave portion 2 along the outer shape of a container, and a male mold 4 fitted in the concave portion 2. The male mold 4 is fitted into the circular concave portion 2 of the female mold 3, and the tableware is press-molded between the two. At the outer edge of the male mold 4 and the outer edge of the female mold 3, stoppers 5, 6 that come into contact when the molds are fitted to each other are arranged. The stopper 5 of the male mold 4 has an exhaust hole along the outside of the fitted portion. 8 are formed.
The exhaust hole 8 penetrates the stopper 5 up and down, from above to below,
Air passes from below to above. A large number of the exhaust holes 8 are arranged along the outer edge with a diameter of 10 mm and an interval of 20 mm. The side surface of the female mold and the side surface of the male mold are formed obliquely, and the angle G with the vertical line is 19.29 °.

If the female die and the male die are separated quickly after pressing, air rapidly moves into the mold, and explosion due to the movement of air occurs. May occur, and this explosion may cause destruction of the pressed product. Therefore, an exhaust hole is formed to prevent this explosion. That is,
When removing the female mold and the male mold, the hot air is exhausted from the exhaust hole and the outside air enters, mitigating the rapid air movement and preventing the explosion due to the air movement when separating the female mold and the male mold. I do.

The male mold 4 fits into the rectangular recess 2 of the female mold 3 and the tableware is pressed between the two. At the outer edge of the male mold 4 and the outer edge of the female mold 3, stoppers 5, 6 that come into contact when the molds are fitted to each other are arranged. The stopper 5 of the male mold 4 has an exhaust hole along the outside of the fitted portion. 8 are formed.
