  The knobs 13 and 13 of the present example are front and rear plates that are foldable so as to be pushed inward by separating lines 14 and 14 and punched portions 15 and 15 with the folding portions 10 and 11 on the left and right side edges adjacent to each other as hinges. 4a and 4b. If it does in this way, by pressing the punching parts 15 and 15 side of the knob | pick parts 13 and 13 with a fingertip, the cutting | disconnection lines 14 and 14 will be made from the location where the cutting | disconnection lines 14 and 14 have reached the punching parts 15 and 15 as a starting point. The knobs 13 and 13 can be easily pushed inward by using the folded parts 10 and 11 at the left and right side edges as hinge parts.

  As described above, if the punched portions 15 and 15 are formed, it becomes easy to perform the cutting along the separation lines 14 and 14, but the punched portions 15 and 15 are omitted and the punched portions 15 and 15 are also formed. It can also be constituted by the separation lines 14 and 14. Note that the separation lines 14 and 14 can be configured by, for example, half cut lines, perforations, intermittent slits, and the like.

  In order to make it easier to hold the knobs 13 and 13 after heating the microwave oven, a heat insulating material (not shown) such as cardboard, synthetic resin foam sheet or cardboard is pasted on the outer surface or inner surface of the knobs 13 and 13. It is preferable to keep it. At the same time, the same heat insulating material is also applied to the region of the front plate 3 facing the knobs 13 and 13 (or the region of the rear plates 4a and 4b when the knobs 13 and 13 are provided on the front plate 3). It is preferable to keep it.

  As shown in FIG. 1 and FIG. 2, the standing pouch 2 for heating the microwave oven housed in the case 1 is automatically opened as the internal pressure rises to release the internal pressure (steam) to the outside when the microwave oven is heated. It is the airtight bag which has the steam release part 16 which can be formed, and has the bottom face part which can become independent. The steam vent 16 in this example includes a weak seal 18 projecting inward from the peripheral seal 17 and a cut 19 cut into the weak seal 18. In the steam vent 16, the weak seal portion 18 is peeled off due to an increase in internal pressure, and the tip of the cut portion 19 is opened to allow the steam to escape. The cut portion 19 also serves as a notch for opening.

  As shown in FIGS. 1, 2, and 5, the standing pouch 2 is inserted between the front plate 3 and the back plates 4 a and 4 b of the case 1 and placed on the bottom plate 5. Further, the bottom plate 5 is folded in a mountain shape as described above, and is inserted into the concave portion at the bottom of the standing pouch 2. The posture of the standing pouch 2 can be stabilized by folding the bottom plate 5 into a chevron and inserting it into the recess of the bottom of the standing pouch 2.

  As shown in FIGS. 1 to 3, the upper left and right corners of the front plate 3 and the back plates 4 a and 4 b of the case 1 are preferably cut off. Although the corner portion may be cut off in an oblique straight line shape, it is preferable that the corner portion is cut off in an outwardly convex arc shape as shown in the figure. By setting it as such a corner shape, when inserting the standing pouch 2 in the case 1, it can become difficult to catch, and it becomes easy to perform insertion. Further, the same effect can be obtained even if the entire upper edge of the case 1 including the corner portion is formed in an outwardly convex gentle arc shape.

  It is preferable that the front plate 3 and the back plates 4 a and 4 b of the case 1 are bonded to the standing pouch 2 at the top. If the upper portions of the front plate 3 and the rear plates 4a and 4b are bonded to the standing pouch 2, the upper portion of the standing pouch 2 is separated and opened, and then the unsealed portion is easily maintained. For this reason, it becomes easy to take out the contents when the contents are not transferred to the tableware but used as it is on the table.
