Before heating, as shown in Fig. 2, the opening/closing part 6,
6' opens by using the outer ends of the contacts 5, 5' or the cut lines 8, 8', 9, 9' as fulcrums due to the pressure of water vapor from contents of instant food, expanded air, etc., and opens the vent hole 7. , 7' is formed, so heat is generated inside the container.
Accumulation of water vapor and the like can be prevented, and therefore, deformation of the container due to heat can be prevented. In this case, the adjacent parts of the opening/closing parts 6, 6' (i.e., the ventilation holes 7,
7') further includes radial cut lines 8,
8', 9, 9', 10, 10', 11, 11', 1
2, 12' are provided so that they can be bent slightly during heating, preventing them from engaging with the peripheral edges of the opening/closing parts 6, 6', and facilitating opening.
