  1-3, the cooking bag 1 for microwave ovens of an example of this invention is shown. The microwave oven cooking bag 1 is formed with an opening O to introduce contents 2 such as ingredients (potato, raw meat, carrots, etc.) I and seasoning liquid S, and ingredients I and seasoning liquid. The main body 3 is configured to hold S and the like, and the wing 4 is formed at one end of the main body 3. An edge heat seal HS, a side end heat seal HS1, and a pocket heat seal HS2 are appropriately applied to edges other than the opening O. And the standing assistance part 5 is formed in the base end side of the introducing | transducing part 2. FIG. The standing assisting part 5 is formed continuously and integrally with the main body part 3 and can hold the ingredients I, the seasoning liquid S and the like. When the ingredients I, seasoning liquid S, and the like enter the standing assistance part 5 and expand the standing assistance part 5, the introduction part 2 stands (that is, the introduction part 2 forms an opening standing area).

  The microwave oven cooking bag 1 is formed of a flexible film having heat-fusibility. This flexible film is formed of a laminate of transparent vapor-deposited PET / DL / ONY / DL / CPP, PET / DL / transparent vapor-deposited ONY / DL / CPP, ONY / DL / light-shielding CPP, and the like.

  As shown in FIGS. 4 and 5, the microwave oven cooking bag 1 is a rectangular heat-adhesive flexible film having the same width of four pieces (even if the widths of the four pieces of films are not the same, they are approximate widths). May be connected by the end heat seal HS and the side end heat seal HS1. The front sheet S1 has a width W1 and a length L1, the back sheet S2 has a width W1 and a length L2 (L2 <L1), and the wing sheet S3 has a width W1 and a length 2 × L3. S4 is formed to have a width W1 and a length L4 + L5 (L4 <L5). The wing sheet S3 forms a wing sheet bent part b1 as a valley fold along the width direction at the center in the length direction. On the other hand, the introducing portion sheet S4 forms an introducing sheet bent portion b2 as a valley fold at a position of a length L4 from the base end S4e.

  In this state, the four sheets are overlapped. That is, the wing part sheet S3 and the introduction part sheet S4 are arranged on the back side of the front side sheet S1, and the back side sheet S2 is arranged on the back side of the wing part sheet S3 and the introduction part sheet S4. At this time, the base end S1e of the front side sheet S1 and the front end S3t of the wing sheet S3, the base end S3e of the wing part sheet S3 and the base end S2e of the back side sheet S2, and further, the front end S2t of the back side sheet S2 And the base end S4e of the introduction portion sheet S4 are arranged so as to overlap each other. Then, the base end S1e of the front side sheet S1 and the front end S3t of the wing part sheet S3, and the base end S3e of the wing part sheet S3 and the base end S2e of the back side sheet S2 are connected by the end part heat seal HS having the width d2. (That is, these are each heat-sealed and bonded).

  Further, the front end S2t of the back side sheet S2 and the base end S4e of the introduction portion sheet S4 are bonded together by an end heat seal HS having a width d3. Furthermore, the side edge heat seal HS1 of width d1 is applied to both sides in the width direction of the front side sheet S1, the back side sheet S2, the wing part sheet S3, and the introduction part sheet S4. In this example, the end heat seal HS and the side end heat seal HS1 are linear and the widths d1, d2, and d3 are the same. However, the present invention is not limited to this, and the heat seal shape and the heat seal are not limited thereto. The width can be appropriately designed according to the purpose. Further, the width W1 of the front side sheet S1, the back side sheet S2, the wing part sheet S3, and the introduction part sheet S4 may not be the same, and the side end heat seal HS1 only needs to be given by a predetermined width d1.

Furthermore, a pocket heat seal HS2 for reinforcement is applied to both ends of the wing sheet bent portion b1, that is, at a place where the wing sheet bent portion b1 and the side end heat seal HS1 intersect with each other for a length d5 (width d1). On the other hand, another pocket heat seal HS2 for reinforcement is provided only at the length d4 (width d1) at both ends of the introduction sheet bent portion b2, that is, at a place where the introduction sheet bent portion b2 and the side end heat seal HS1 intersect. Apply. Note that heat sealing is not performed so that the opening O can be formed at the position where the leading edge S1t of the front sheet S1 and the leading edge S4t of the introducing portion sheet S4 overlap. In this example, the length of the heat seal HS 2 d4, d5 is the same, but is not limited thereto. In addition, in this example, the pocket heat seal HS2 for reinforcement was applied to the portion where the wing sheet bent portion b1 and the side end heat seal HS1 intersect and to both ends of the introduction sheet bent portion b2. It is not limited and it is not necessary to give the pocket part heat seal HS2 for reinforcement.

  By the wing sheet S3 and the front sheet S1 (ie, between the wing sheet bent part b1 and the front sheet S1), the wing pocket PK1 is formed by the wing sheet S3 and the back sheet S2 (ie, the wing sheet bent part). Each wing pocket PK2 is formed between b1 and the back sheet S2. The wing pockets PK1 and PK2 are not heat-sealed except at both ends thereof at the wing sheet bent portion b1, and thus communicate with the main body 3 so that the ingredients I, seasoning liquid S, and the like are from the main body 3. It has a structure that can enter. Further, the introducing portion pocket PK3 is formed by the introducing portion sheet S4 and the back side sheet S2 (that is, between the introducing sheet bent portion b2 and the back side sheet S2). Since the introduction portion pocket PK3 is not heat-sealed except at both ends of the introduction sheet bent portion b2, it is in communication with the main body portion 3, and the structure I and the seasoning liquid S can enter from the main body portion 3. It has become. Further, as in this example, when only the edge portions of the wing pockets PK1, PK2 and the introduction portion pocket PK3 are heat sealed, the ingredients I and the seasoning liquid S are the wing pockets PK1, PK2, the introduction portion pocket PK3. Therefore, the ingredients I and the seasoning liquid S can be taken out smoothly.

  Next, a method of cooking with the microwave oven cooking bag 1 will be described with reference to FIGS. First, the microwave oven cooking bag 1 is made to stand by the wing pockets PK1, PK2 (with the wing pockets PK1, PK2 down). Then, the seasoning liquid S contained therein flows into the wing pockets PK1, PK2, and stabilizes the self-supporting of the microwave oven cooking bag 1. (At this time, the opening O is positioned at the upper end. Alternatively, the opening O is formed by cutting off the upper end of the microwave cooking bag 1 in the width direction). Then, the ingredient I is introduced from the opening O into the main body portion 3 of the cooking bag 1 for microwave oven in which the seasoning liquid S is previously introduced. At this time, the ingredient I and the seasoning liquid S enter the wing pockets PK1, PK2 from the main body 3, and the wing pocket PK1 and the wing pocket PK2 expand outward (that is, the wing sheet S3). When the wing sheet bent portion b1 expands to form one chamber and the wing portion 4 is formed, the microwave oven cooking bag 1 can be more stable and independent (at this time, the wing portion 4 becomes the bottom surface). In this example, the seasoning liquid S is input in advance, but the present invention is not limited to this, and the seasoning liquid may be input simultaneously with the ingredients or after the ingredients are added.

  Next, the microwave oven cooking bag 1 is tilted in the direction of the arrow (FIG. 6A). At this time, the cooking bag 1 for microwave oven is laid in the direction of the arrow so that the surface with the introduction portion pocket PK3 (that is, the back surface sheet S2 side) is faced down (sideways). Thereby, the ingredient I and the seasoning liquid S enter the introduction portion pocket PK3 from the main body portion 3, and the introduction portion pocket PK3 is expanded to form the standing assisting portion 5 (FIG. 6B). In addition, since the movement of the introduction portion pocket PK3 is restricted by the side end heat seal HS1 when it swells, the introduction portion 2 rises (the opening O faces upward) and becomes bowed toward the main body portion 3 side. Become. Since the introduction part 2 is bowed, the front sheet S1 and the introduction part sheet S4 constituting the introduction part 2 closely overlap each other, and the opening O is closed. As a result, the entry and exit of air between the main body portion 3 and the outside of the microwave cooking bag 1 is blocked.

  In such a state, the cooking bag 1 for microwave oven is inserted into the microwave oven, and heating cooking is started. When a certain period of time elapses after heating is started, the ingredients I and seasoning liquid S in the microwave oven cooking bag 1 are warmed and the water vapor increases to expand and the internal pressure in the microwave oven cooking bag 1 increases. . Since the introduction part 2 is only a bow to close the opening O, a gap is formed in the introduction part 2 when the internal pressure becomes a constant magnitude, thereby forming a slight gap in the opening O as well. The That is, an air passage is formed between the main body 3 and the outside. The air in the main body 3 can be released to the outside through the air passage, and as a result, the internal pressure in the main body 3 is appropriately reduced. Since the front side sheet S1 and the introduction part sheet S4 overlap each other and form a bow, when the internal pressure in the main body part 3 decreases to a certain level, the gap between the front side sheet S1 and the introduction part sheet S4 is closed and opened. O closes.

  Since it is comprised in this way, before the internal pressure of the main-body part 3 increases very much, the air in the main-body part 3 can be escaped outside, and an internal pressure can be lowered | hung. For this reason, the ingredients I and the seasoning liquid S can be prevented from being blown out from the opening O through the introduction portion 2. Further, the fact that the opening O is arranged upward in the substantially vertical direction also contributes to preventing the ingredients I and the seasoning liquid S from blowing out from the opening O. In addition, since the introduction portion 2 is provided, the opening O is not directly connected to the main body portion 3, and when the air pressure of the main body portion 3 increases and air escapes from the opening O, the ingredients I and the seasoning liquid S should be used. Even when carried with air, these can be retained in the introduction part 2 and contribute to preventing the ingredients I and the seasoning liquid S from blowing out from the opening O.

  In this example, four sheets, the front sheet S1, the back sheet S2, the wing sheet S3, and the introduction sheet S4 are bonded together by the end heat seal HS, the side end heat seal HS1, and the pocket heat seal HS2. Although the cooking bag 1 for a range is comprised, this invention is not limited to this, As shown in FIG. 7, these four sheets are comprised by one sheet | seat which continued, This is folded and desired You may form the cooking bag for microwave ovens by heat-sealing with a heat seal, forming a shape.

  In this example, one heat-sealable flexible sheet SH (length: L1 + 2 × L3 + L2 + L4 + L5, width: W1) is folded back in the longitudinal direction so that the front end St and the base end Se overlap each other. Form. Specifically, the sheet SH is folded in a mountain at a position of a length L1 in the longitudinal direction from the leading end St to form the first bent portion B1. Further, the sheet SH is folded at a position at a length L3 from the first bent portion B1 to form a second bent portion B2. Further, the sheet SH is folded in a mountain at a position of a length L3 from the second bent portion B2, thereby forming a third bent portion B3. Further, the sheet SH is folded in a mountain at a position of a length L2 from the third bent portion B3 to form a fourth bent portion B4. Further, the sheet SH is valley-folded at the position of the length L4 from the fourth bent portion B4 to form the fifth bent portion B5.

Then, the end heat seal HS (length d2) is applied to the first bent portion B1 and the third bent portion B3 along the width direction thereof. Further, the end heat seal HS (length d3) is applied to the fourth bent portion B4 along the width direction (in this example, d2 = d3, but is not limited thereto). Then, both side portions of the second bent portion B2 and the fifth bent portion B5 that are valley-folded (that is, (1) the sheet portion between the first bent portion B1 and the second bent portion B2, and the second bent portion A sheet portion between B2 and the third bent portion B3, and (2) a sheet portion between the fourth bent portion B4 and the fifth bent portion B5, and the fifth bent portion B5 and the sheet SH . The side portions in the width direction of the folded sheet SH are bonded together by the side heat seal HS1 so that the sheet portion between the base end Se and the base end Se is not bonded. In this example, the end heat seal HS applied along the width direction of the first bent portion B1, the third bent portion B3, and the fourth bent portion B4 may be omitted. You may make it apply to. Further, the pocket heat seal HS2 is applied at the position where the second bent portion B2 and the side heat seal HS1 overlap to reinforce the wing portion pockets PK1, PK2. Further, the pocket heat seal HS2 is applied at the position where the fifth bent portion B5 and the side heat seal HS1 overlap to reinforce the introduction portion pocket PK3. The pocket heat seal HS2 for reinforcement need not be provided.

  Note that the front end St and the base end Se of the sheet SH are not subjected to heat sealing, and an opening O is formed.

  In the microwave oven cooking bag 100 formed in this way, the ingredient I is put in a standing state and placed horizontally. As a result, the introduction portion pocket PK3 formed between the fourth bent portion B4 and the fifth bent portion B5 is swollen by the entry of the ingredient I and raises the opening O upward. The operation of raising the introduction portion pocket PK3 when the ingredient I enters the introduction portion pocket PK3 and raising the opening O upward is the same as in the above-described example.

  In addition, this invention is not limited to the above-mentioned example, You may form from the sheet | seat of multiple pieces other than four pieces.

  FIG. 8 shows another example of the present invention. In the microwave oven cooking bag 1 ′ in this example, the width of the introduction part heat seal HS ′ formed in the introduction part (configured by the introduction part sheet and the top sheet: opening upright region) is defined as d6 ′ (> d1). Yes. Then, a pair of cuts C1 and C2 are formed in this portion (a pair of cuts C1 and C2 constitute a multiplying portion). The cut C1 is formed in a J-shape, and has a length D4 and a width D3. The cut C2 is formed in a straight line and has a length D4. These cuts C1 and C2 are formed at positions separated from the imaginary folding line K by a distance D1 (distance from the folding imaginary line K to the short side of the J character) and a distance D2 (D1 = D2). Is desirable). The lengths D4 of the cuts C1 and C2 need to be smaller than the width d6 ′ of the introduction part heat seal HS ′ (if D4> d6 ′, the cuts reach the introduction part, and the contents and seasonings Because liquid leaks out).

  Another point different from the previous example is the length L5 ′ from the pocket heat seal HS2 to the opening O ′. In this example, since the introduction part is folded in two with the folding virtual line K as a boundary, it is set longer than the above example (L5 ′> L5). Accordingly, the entire length L1 ′ of the microwave oven cooking bag 1 is also longer than the above example. Other configurations, shapes, dimensions, and the like are the same as those in the above-described example, and thus description thereof is omitted.

  Next, a method of cooking with the microwave oven cooking bag 1 'will be described with reference to FIG. First, the microwave oven cooking bag 1 'is made to stand by the wing pockets PK1, PK2 (with the wing pockets PK1, PK2 down). Then, the seasoning liquid S contained therein flows into the wing pockets PK1, PK2, and stabilizes the self-supporting of the microwave oven cooking bag 1 '. (At this time, the opening O ′ is located at the upper end. Alternatively, the opening O is formed by cutting off the upper end of the cooking bag 1 ′ for the microwave oven in the width direction). And the ingredient I is thrown into the main-body part of the cooking bag 1 'for microwave ovens into which the seasoning liquid S is thrown beforehand from opening O'. At this time, the ingredient I and the seasoning liquid S enter the wing pockets PK1 and PK2 from the main body 3 ', and the wing pocket PK1 and the pocket PK2 expand outward to form a chamber and form the wing 4'. By doing so, the microwave oven cooking bag 1 ′ can be more stably self-supporting (FIG. 9A; at this time, the wing portion 4 ′ is the bottom surface). In this example, the seasoning liquid S is input in advance, but the present invention is not limited to this. The seasoning liquid S may be input simultaneously with the ingredients I or after the ingredients I are added.

  Next, the microwave oven cooking bag 1 'is tilted in the direction of the arrow (FIG. 9B). At this time, the microwave oven cooking bag 1 ′ is laid down in the direction of the arrow so that the side with the introduction portion pocket PK 3 (that is, the back sheet side) is faced down (sideways). As a result, the ingredient I and the seasoning liquid S enter the introduction portion pocket PK3 from the main body portion 3 ′, and the introduction portion pocket PK3 is expanded to form the standing assisting portion 5 ′. In addition, since the movement of the introduction portion pocket PK3 is restricted by the side heat seal HS1 when it swells, the introduction portion 2 'stands up (the opening O faces upward). Then, the opening O ′ is folded back to the surface side along the bending imaginary line K of the introduction portion 2 ′ to form a bending portion M. Further, the cut C1 formed in the introduction part heat seal HS ′ is cut and raised, inserted into the cut C2, and the cut C1 is hooked on the cut C2. This is done for each of the left and right. Thereby, introduction part 2 'is bent and the entrance / exit of the air in and out of main part 3' and the outside of cooking bag 1 'for microwave ovens is blocked much more than the previous example (FIG. 10). Further, since the notch C1 is hooked on the notch C2, the bent introduction portion 2 'is maintained in the bent state.

In such a state, the cooking bag 1 for microwave oven is inserted into the microwave oven, and heating cooking is started. When a certain period of time elapses after heating is started, the ingredients I and seasoning liquid S in the microwave oven cooking bag 1 are warmed and the water vapor increases to expand and the internal pressure in the microwave oven cooking bag 1 increases. . Since the introduction part 2 ′ is only bowed to close the opening O, a gap is formed in the introduction part 2 ′ when the internal pressure becomes constant. In this example, since the introduction part 2 ′ is bent to provide the bent part M, the air passage is less likely to be formed than in the previous example. That is, an air passage is not formed between the main body 3 ′ and the outside unless the internal pressure in the main body 3 ′ is higher than in the previous example. The air in the main body portion 3 ′ can be released to the outside through the air passage, and as a result, the internal pressure in the main body portion 3 ′ is appropriately reduced. When the internal pressure of the main body portion 3 ′ is lowered to a certain level, the state where the introduction portion 2 ′ is folded by the notch C1 and the notch C2 is maintained, so that this air passage is blocked.

  Since it is comprised in this way, before the internal pressure of main-body part 3 'increases very much, the air in main-body part 3' can be released outside, and an internal pressure can be lowered | hung. For this reason, the ingredients I and the seasoning liquid S can be prevented from being blown out from the opening O ′ through the introduction portion 2 ′. Further, the fact that the opening O ′ is arranged upward in the substantially vertical direction also contributes to preventing the ingredients I and the seasoning liquid S from being blown out from the opening O ′. In addition, since the introduction portion 2 ′ is provided, the opening O ′ is not directly connected to the main body portion 3 ′, and when the internal pressure of the main body portion 3 ′ increases and air escapes from the opening O ′, the ingredients I and Even if the seasoning liquid S is carried with air, these can be retained in the introduction part 2 and contribute to preventing the ingredients I and the seasoning liquid S from being blown out from the opening O ′. Furthermore, since the bent part M is formed in the introduction part 2 ′, if the internal pressure in the main body part 3 ′ is not higher than in the previous example, an air passage is not formed, and cooking requiring steam or steaming is performed. Suitable if you want to. Furthermore, since the bent portion M is maintained by hooking the notch C1 on the notch C2, this pressure can be further maintained.

  Note that the shapes of the cuts C1 and C2 are not limited to this example, and any shape may be used as long as it has a function of easily closing the cooking bag by multiplying the two cuts. Further, in order to facilitate folding, a sewing machine serving as a folding auxiliary line may be formed between the notches C1 and C2 in the same straight line as the folding virtual line.

  Further, the folding imaginary line K may be printed on the introduction portion sheet so that the folding imaginary line K can be easily seen, thereby forming a folding standard line. Further, the shape of the hooking portion is not limited to this example, and may be any shape as long as the introduction portion can be bent and hooked.

  The present invention is not limited to the above example, and can be applied to a cooking bag for a microwave oven formed of all materials.
