The present invention relates to a cooking pouch, and more particularly, to a cooking pouch that has a reduced manufacturing unit price and is used to heat food by placing food inside the cooking pouch and putting the cooking pouch inside a microwave, and the cooking pouch enabling steam generated in a cooking process to be appropriately discharged so that excellent food texture and taste may be obtained.

First claim

What is claimed is:

1. A cooking pouch comprising:
a sheet having edges fused to one another to form an internal space; and
a zipper coupled to the inner surface of the sheet and partitioning the internal space into first and second spaces,
wherein the first space of the internal space is below the zipper and the second space of the internal space is above the zipper, and
a sealing part at which the zipper and the sheet are fused with each other and
a non-sealing part at which the zipper and the sheet are not fused with each other
are between the zipper and the sheet; wherein the zipper comprises
a plate part which comes in contact with the inner surface of the sheet and of which at least a portion is fused with the sheet, and
a fastener part protruding from the plate part, for opening/closing the cooking pouch,
the non-sealing part comprises a first non-sealing region, and
the first non-sealing region extends in an up/down direction and is opened in the up/down direction by crossing at least a portion of the sealing part in the up/down direction such that the first space communicates with the second space,
wherein the sealing part comprises a first sealing region and a second sealing region formed below and above the fastener part, respectively, and
the non-sealing part further comprises a second non-sealing region located between the first sealing region and the second sealing region.

2. The cooking pouch of claim 1 , wherein a width of the first non-sealing region in a left/right direction is greater than or equal to 10 mm and less than or equal to 30 mm.

3. The cooking pouch of claim 1 , wherein, in the first non-sealing region, a left/right-direction width of a part adjacent to the first space is greater than a left/right-direction width of a part adjacent to the second space.

4. The cooking pouch of claim 1 , wherein the first non-sealing region comprises:
a (1-1)th non-sealing region located on the same line as the first sealing region; and
a (1-2) th non-sealing region located on the same line as the second sealing region.

5. The cooking pouch of claim 1 , wherein, in the (1-1)th non-sealing region, a left/right-direction width of a part adjacent to the first space is greater than a left/right-direction width of a part adjacent to the second space.

6. The cooking pouch of claim 4 , wherein, in the (1-2) th non-sealing region, a left/right-direction width of a part adjacent to the first space is greater than a left/right-direction width of a part adjacent to the second space.

7. The cooking pouch of claim 1 , wherein the first space has a greater volume than the second space.

8. The cooking pouch of claim 1 , wherein the sheet comprises:
a first notch provided at a side part thereof and located below the zipper; and
a second notch provided at the side part thereof and located above the zipper.

9. The cooking pouch of claim 2 , wherein the first space has a greater volume than the second space.

10. The cooking pouch of claim 3 , wherein the first space has a greater volume than the second space.

11. The cooking pouch of claim 4 , wherein the first space has a greater volume than the second space.

12. The cooking pouch of claim 5 , wherein the first space has a greater volume than the second space.

13. The cooking pouch of claim 6 , wherein the first space has a greater volume than the second space.
