た。First, in order to prevent the bag body from bursting, when the bag body is once taken out from the bag and cooked, or when the water content is higher than a certain level, such as a cooked product with a high water content or a cooked product that requires soup stock, etc. When cooking what I had, I couldn't cook well because the water evaporated more than necessary. In addition, when cooking rice, which requires a certain pressure during cooking, it is impossible to apply pressure when it is placed in a plate or the like, and it cannot be cooked as it is. Although it can be solved by giving strength to the bag and sealing the contents of the cooked product with strength, these are not only expensive, but they can be easily sealed at home,
It wasn't something I could use. In such a case, for example, it is very inconvenient to use a special container or the like made of pottery or the like to which pressure is applied according to the cooked product.

望まれている。Alternatively, for example, when an attempt is made to release pressure by making a hole in the bag itself with the cooked product kept inside the bag, the strength of the bag is reduced and the contents leak or the like. Is caused. Therefore, there is a need for some sort of solution that allows cooking with a large amount of water, which cannot be cooked in a microwave oven, in a bag.
In particular, some special bag body is desired in order to widen the range of utilization of the microwave oven which is widely used for easy cooking at present.

る。The substantially triangular protruding portion 81 of the first chuck portion 5 is firmly fitted by the holding piece 91 and cannot be opened unless a certain force is applied, whereas the second chuck portion 6 is substantially triangular. By lowering the angle of the protruding portion 82 of the upper protruding portion 81 to make it into a substantially circular shape or the like, even when sandwiched by the sandwiching piece 91, the catching force is weak and the sandwiching force becomes low, so the opening is performed under a pressure below a certain level. It becomes possible to do. Therefore, when the pressure inside the bag body 1 becomes stronger, the second chuck portion 6 is opened first, and when pressure is applied from this second chuck portion 6 to a portion ahead of the second chuck portion 6, the pressure relief portion 7 is formed inside the bag body 1. The pressure is discharged to the outside from the pressure relief portion 7 since the pressure relief portion 7 communicates with the pressure relief portion 7. This means that the second chuck portion is opened before the pressure for opening the first chuck portion 5 is applied, and the subsequent increase in pressure is discharged from the pressure relief portion 7 to the outside, and the inside of the bag body 1 is kept constant. The first chuck portion 5 can be kept closed under pressure.
