FIG. 19 shows an example of the heating process. A heating process is implemented as follows. The standing pouch 10 is heated by heating means. A heating means is, for example, a microwave oven. As the standing pouch 10 is heated, the pressure in the accommodation space A20 increases. The water vapor in the accommodation space A20 passes through the weak coupling portion 82 of the vaporizing portion 11 and flows to the outside of the standing pouch 10 .

(effect)
Effects obtained by the standing pouch 10 are exemplified below.
In one example of standing pouch 10 , seal 100 includes side closure seal 300 . Lateral closure seal portion 300 includes a lateral interior 320 . The side inner portion 320 is provided in the passage inner portion A42.

According to the above configuration of the standing pouch 10, the following effects can be obtained, for example. The side passage A40 is difficult to expand during heating of the standing pouch 10. - 特許庁It is difficult for the contents C to flow from the storage space A20 toward the side passage A40. Therefore, the shape of the standing pouch 10 is less likely to be deformed due to heating.

The state in which the shape of the standing pouch 10 is deformed is, for example, a state in which the standing pouch 10 is tilted with the inner portion 211B of the first seal portion 211 of the lower unit seal portion 210D as a starting point. As an example thereof, the side passage portion 60, the upper passage portion 50, and the body portion 30 protrude outward in the widthwise direction with respect to the inner portion 211B and are inclined to approach the installation surface.

When the standing pouch 10 is tilted, the content C and the additional content D are biased toward the tilted portion of the standing pouch 10, so that the content C and the additional content D pass through the upper passage A30 and reach the standing pouch 10. There is a high possibility that it will flow to the outside of the

In one example of the standing pouch 10, the lateral interior 320 is provided to fit in the lateral passage A40.
According to the above configuration of the standing pouch 10, for example, the following effects can be obtained. The accommodation space A20 is easily expanded while the standing pouch 10 is being heated.

According to the above configuration of the standing pouch 10, the following effects can be obtained, for example. Since the side inner part 320 is provided at a position apart from the first sealing part 211 in the height direction, the chuck holding the standing pouch 10 and the heat sealing device are less likely to interfere in the side sealing process.

In one example of the standing pouch 10, the length of the compartment A43 in the height direction is shorter than the length of the lateral interior 320 in the height direction.
According to the above configuration of the standing pouch 10, for example, the following effects can be obtained. The volume of the partitioned portion A43 is reduced, and the amount of the content C staying in the partitioned portion A43 is reduced.

In one example of the standing pouch 10, the length of the partition part A43 in the width direction is shorter than the length of the first seal part 211 of the unit seal part 210 in the width direction.
According to the above configuration of the standing pouch 10, for example, the following effects can be obtained. The volume of the partitioned portion A43 is reduced, and the amount of the content C staying in the partitioned portion A43 is reduced.

In one example of standing pouch 10 , lateral closure seal 300 includes lateral exterior 310 . The lateral interior 320 is located in the widthwise direction with respect to the lateral exterior 310 . The lateral exterior 310 closes off the passageway outer portion A41 of the lateral passageway A40.

According to the above configuration of the standing pouch 10, the following effects can be obtained, for example. Since the side exterior 310 that closes the side passage A40 is provided in the width outward direction from the passage inner portion A42, interference between the chuck holding the standing pouch 10 and the heat sealer is less likely in the side sealing step.

In one example of standing pouch 10 , lateral interior 320 connects to lateral exterior 310 .
According to the above configuration of the standing pouch 10, for example, the following effects can be obtained. The lateral closure seal 300 can be integrally formed.

In one example of the standing pouch 10, the passage-constituting seal portion 200 includes an upper unit seal portion 210U positioned upward with respect to the side passage A40. Upper unit seal portion 210U includes first seal portion 211 and second seal portion 212 . The first seal portion 211 includes an outer portion 211</b>A positioned in the width outer direction with respect to the second seal portion 212 .

According to the above configuration of the standing pouch 10, the following effects can be obtained, for example. When the nozzle is inserted into the side passage A40 and the chuck grips the second seal portion 212 of the upper unit seal portion 210U or a portion positioned in the width direction with respect to the second seal portion 212, the nozzle and the chuck is difficult to interfere with.

In one example of the standing pouch 10, the passage-constituting seal portion 200 includes a lower unit seal portion 210D positioned downward with respect to the side passage A40. Lower unit seal portion 210</b>D includes first seal portion 211 and second seal portion 212 . The first seal portion 211 includes an outer portion 211</b>A positioned in the width outer direction with respect to the second seal portion 212 .

According to the above configuration of the standing pouch 10, the following effects can be obtained, for example. When the nozzle is inserted into the side passage A40 and the chuck grips the second seal portion 212 of the lower unit seal portion 210D or a portion located in the width direction with respect to the second seal portion 212, the nozzle and the chuck is difficult to interfere with.

In one example of the standing pouch 10, the inner edge Q located in the innermost width direction in the lateral interior 320 is located on the reference line LQ1 or in the outer width direction with respect to the reference line LQ1.
According to the above configuration of the standing pouch 10, for example, the following effects can be obtained. When the standing pouch 10 is heated, the accommodation space A20 is easily expanded.

In one example of the standing pouch 10, the inner edge Q located in the innermost width direction in the lateral interior 320 is located on the reference line LQ2 or in the outer width direction with respect to the reference line LQ2.
According to the above configuration of the standing pouch 10, for example, the following effects can be obtained. When the standing pouch 10 is heated, the accommodation space A20 is easily expanded.

In the example of the standing pouch 10, the inner edge Q located in the innermost width direction in the lateral interior 320 is located in the outer width direction with respect to the reference line LQ2. The distance in the width direction between the inner edge Q and the reference line LQ2 is less than or equal to the length of the lateral outer portion 310 in the width direction, or less than or equal to the length of the lateral inner portion 320 in the width direction.

According to the above configuration of the standing pouch 10, for example, the following effects can be obtained. When the standing pouch 10 is heated, the side passage A40 becomes difficult to expand.

(Example)
See FIG. FIG. 30 shows an example of the results of measurement tests for measuring the properties of the standing pouch 10. FIG. The measurement item in the measurement test is the posture of the standing pouch 10 during heating.

In the measurement test, a small microwave oven was selected as the heating method. The type of small microwave oven is a turntable type. In the measurement test, a standing pouch 10 conforming to the configuration of the standing pouch 10 of the first embodiment was used as a sample. The dimensions of each part of the sample were selected as follows.

The height of the standing pouch 10 is called "pouch height". As an example, the distance between the outer edge E33 and the outer edge E45 in the height direction is defined as the pouch height. Pouch height can be selected, for example, from a range of 150 mm to 200 mm. The sample pouch height is 170 mm. In this example, the pouch height was selected in consideration of the fact that the interior height of the small microwave oven is about 150 mm.

The width of the standing pouch 10 is called "pouch width". As an example, the distance between the outer edge E10 and the outer edge E29 in the width direction is defined as the pouch width. The pouch width can be selected, for example, from a range of 170mm to 250mm. The sample pouch width is 210 mm.

The offset amount of the side passage portion 60 in the height direction with respect to the reference position of the upper end portion 10C is referred to as "upper offset amount". As an example, the distance between the outer edge E33 and the outer edge E23 in the height direction is defined as the upward offset amount. For example, the upper offset amount can be selected from a range of 25 mm to 50 mm. The upward offset amount of the sample is 37 mm.

The offset amount of the side passage portion 60 in the height direction with respect to the reference position of the lower end portion 10D is referred to as "downward offset amount". As an example, the distance between the outer edge E45 and the outer edge E27 in the height direction is defined as the downward offset amount. For example, the downward offset amount can be selected from a range of 25 mm to 50 mm. The downward offset amount of the sample is 37 mm.

The amount of protrusion of the side passage portion 60 in the width direction with respect to the reference position of the second side portion 10B is referred to as "side passage height". As an example, the outer edge E22 is set as the reference position of the second side portion 10B. The distance between the outer edge E22 and the outer edge E29 in the width direction is defined as the side passage height. The side passage height can be selected, for example, from a range of 0 mm to 20 mm. The lateral passage height of the sample is 12 mm.

The length of the side passage portion 60 in the height direction is called "side passage width". As an example, the width of the side passage is defined as the distance between the outer edge E23 and the outer edge E27 in the height direction. The lateral passage width can be selected, for example, from a range of 40 mm to 140 mm. The lateral passage width of the sample is 96 mm.

There are three types of factors related to samples. The contents of the two factors are the distance difference LX and the compartment width LC. The distance difference LX is the value obtained by subtracting the lateral inner width LB from the inner edge spacing LA. The inner edge interval LA is the distance between the inner edge QD13 of the lower unit seal portion 210D and the inner edge QS2 of the side outer portion 310 in the width direction. Lateral inner width LB is the distance between first side 321A and second side 321B of lateral inner 320 . The partition width LC is the distance between the inner edge QT2 of the side inner portion 320 and the inner edge QD11 of the lower unit seal portion 210D in the height direction.

There are 6 levels for the distance difference LX. The contents of the 6 levels are 10mm, 9mm, 7mm, 5mm, 3mm and 0mm. There are 7 levels for the compartment width LC. The contents of the seven levels are 0mm, 10mm, 20mm, 25mm, 30mm, 35mm and 40mm. The measurement test used 36 samples based on a combination of two factors.

In the example where the lateral inner width LB is set to 0 mm, the lateral closure seal portion 300 does not include the lateral inner 320 but only the lateral outer 310 . In the example where the partition width LC is set to 0 mm, the side passage A40 does not include the lower partition A43D. The inner edge QT of the side inner portion 320 overlaps the inner edge QD of the lower unit seal portion 210D.

In the example where the distance difference LX is set to 0 mm, the position of the first side edge 321A of the side inner portion 320 of the side closed seal portion 300 in the width direction is the same as the position of the inner edge QD13 of the lower unit seal portion 210D.

In the measurement test, samples manufactured according to the following conditions were used. Sauce for mapo tofu was selected as content C. The weight of content C is 130 g. A plurality of cut silken tofu was selected as additional content D. The weight of additional content D is 350 g.

In the measurement test, the samples were heated according to the following conditions. The output of the small microwave oven during heating is 600W. The heating time with a small microwave oven is 4 minutes.
In the measurement test, the shape of the standing pouch 10 was visually confirmed after heating. "A" in the figure indicates the case where the following state is confirmed. The shape of the standing pouch 10 does not collapse. "B" in the figure indicates the case where the following state is confirmed. The shape of the standing pouch 10 is deformed, and the degree of deformation is small. "C" in the figure indicates the case where the following state is confirmed. The shape of the standing pouch 10 is deformed, and the degree of deformation is large. A state in which the degree of shape collapse is large is a state in which the content C and the additional content D are highly likely to flow out of the standing pouch 10 or have flowed out of the standing pouch 10 .

The following trends were confirmed from the results of the measurement test. As the distance difference LX becomes shorter, the shape of the standing pouch 10 is less likely to collapse. The shorter the partition width LC, the less likely the shape of the standing pouch 10 will collapse.

It should be noted that the forms that the standing pouch according to the present invention can take are not limited to the descriptions given in the above embodiments. Standing pouches relating to the present invention may take forms different from those exemplified in each embodiment. Examples include a form in which a part of the configuration of each embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to each embodiment.

(12th embodiment)
A pouch for microwave cooking according to a twelfth embodiment will be described below with reference to the drawings. FIG. 31 is a schematic plan view showing one embodiment of the microwave cooking pouch 401 according to the present invention. 32 is a schematic plan view showing an unsealed state of the pouch for microwave cooking shown in FIG. 31. FIG. Moreover, FIG. 34 is a cross-sectional schematic diagram showing an example of the layer structure of the laminate 420 that constitutes the pouch for microwave cooking 401 according to the present invention.

The pouch 401 for microwave cooking according to the present invention includes two laminates 420 having at least a base material layer 421 and a sealant layer 428, that is, the sealant layers of the surface laminate 407 and the back laminate 407 are opposed to each other, and 2, a bottom tape 408 having at least a base layer 421 and a sealant layer 428 is folded in half so that the sealant layer 428 faces outward, and the periphery is heat-sealed to form a standing pouch.

One of the top seal portion 402 and the side seal portion 403 is heat-sealed, and the other side seal portion 403 is a filling opening 409 partially protruding from the side seal portion. A filling seal portion 405 is formed by heat-sealing after the content is filled. The other side of the side seal portion 403 corresponds to the inner portion 211B of the first seal portion 211 and the inner portion 212B of the second seal portion 212 of the first embodiment. The filling opening 409 corresponds to the side passage portion 60 of the first embodiment. The filling seal portion 405 corresponds to the side closing seal portion 300 of the first embodiment.

The pouch 401 for microwave cooking according to the present invention is characterized in that the distance A by which the filling seal portion 405 protrudes from the side seal portion 403 satisfies 0 mm≦A≦9 mm. When A is within this range, when the pouch filled with the contents is heated in a microwave oven, the pouch is bent in the vicinity of the filling seal part 405, and the whole is tilted, and in some cases, the contents may spill. I have nothing to do.

As for the distance A, as a result of experiments, it has been found that it is more desirable that 0 mm≦A≦7 mm.
In the example shown in FIGS. 31 and 32, an opening start portion 410 and an opening guide line 411 starting from the opening start portion 410 are applied to the upper portion of the pouch. The opening guide line 411 is a half-cut line and has the effect of bringing about smooth opening. A laser beam or a blade is used to form the half-cut lines.

(13th embodiment)
FIG. 33 is a schematic plan view showing a pouch 401 for microwave cooking according to the thirteenth embodiment. In this example, an opening guiding line 411 with different shapes starting from an opening starting portion 410 is applied to the upper portion of the pouch, and a fastener 412 is provided below the opening guiding line. By doing so, when opening the fastener, the end portions of the laminated body on the front and back sides are displaced, so that it is easy to grasp by hand and opening is facilitated.

In addition to this, although not shown, a steam release mechanism may be provided in addition to the fastener. By doing so, it is possible to safely release the water vapor that is generated when ingredients are added after the package is opened, the zipper is closed, and the package is heated in a microwave oven.

The laminate that makes up the pouch will be explained. FIG. 34 is a schematic cross-sectional view showing an example of the layer structure of the laminate 420 that constitutes the pouch for microwave cooking 401 according to the present invention. In this example, a printed layer 422 is formed on the back surface of a base material layer 421, and the printed base material layer 421, gas barrier layer 424, intermediate layer 426, and sealant layer 428 are composed of adhesive layers 423, 425, and 425, respectively. 427.

The base material layer 421 and the sealant layer 428 are essential, and the other layers can be omitted or have two or more roles. For example, if a gas-barrier synthetic resin film is used as the intermediate layer, the gas-barrier layer can be omitted. Also, if an inorganic oxide deposition film is used as the substrate layer, it can also serve as a gas barrier layer.

As the base material layer 421, a synthetic resin film having printability is used because it often serves as a base material for printing. Examples include oriented polyethylene terephthalate (PET) resin film, oriented nylon film (ONy), and oriented polypropylene (OPP) resin film.

The intermediate layer 426 is often added for the purpose of improving the strength and stiffness of the laminate 420, and nylon film, PET film, PP film, etc. can be used.

As the sealant layer 428, polyolefin resins are generally used. Specifically, low density polyethylene resin (LDPE), medium density polyethylene resin (MDPE), linear low density polyethylene resin (LLDPE), ethylene- Ethylene-based resins such as vinyl acetate copolymer (EVA), ethylene-α-olefin copolymer, ethylene-methacrylic acid resin copolymer, blend resin of polyethylene and polybutene, homopolypropylene resin (PP), propylene- Polypropylene resins such as ethylene random copolymers, propylene-ethylene block copolymers and propylene-α-olefin copolymers are used. In the case of the pouch for microwave cooking according to the present invention, it is desirable to use a polypropylene-based resin in consideration of heat resistance because it is assumed to be heated by a microwave oven.

As the adhesive used for laminating each layer, a general adhesive for dry lamination can be used. Hereinafter, the pouch for microwave cooking according to the present invention will be described more specifically based on examples and comparative examples.
<Example 1>
A printed layer was formed on the deposition surface of a 12 μm-thick polyethylene terephthalate resin film (GL film manufactured by Toppan Printing Co., Ltd.) having silicon dioxide deposited on the back surface as a base layer. A oriented nylon film with a thickness of 15 μm was used as an intermediate layer, and a non-oriented polypropylene resin film with a thickness of 60 μm was used as a sealant layer, and these were laminated together using a dry lamination adhesive to form a laminate.

Using this laminate, a standing pouch as shown in FIG. 32 was prepared, which was filled with 130 g of mapo tofu sauce, and the filling opening was sealed. At this time, as shown in FIG. 35(a), the filling seal portion and the side seal portion were positioned at the same position, that is, the value of A was set to 0 mm.

After subjecting this package to retort sterilization treatment at 120 ° C. for 30 minutes, the upper part is opened, 350 g of silken tofu (1 to 2 cm square diced) is added, and heated in a 600 W microwave oven for 4 minutes. Observed.

The evaluation criteria were as follows.
〇: The side seal part does not break, or the contents do not leak because it breaks above the stepped part. △: The pouch tilts, but the contents do not leak ×: The pouch tilts and the contents leak <Example 2>
As shown in FIG. 35(b), a pouch was produced in the same manner as in Example 1, except that the value of A was 3 mm, and evaluated in the same manner.
<Example 3>
As shown in FIG. 35(c), a pouch was produced in the same manner as in Example 1, except that the value of A was 5 mm, and evaluated in the same manner.
<Example 4>
As shown in FIG. 35(d), a pouch was produced in the same manner as in Example 1, except that the value of A was 7 mm, and evaluated in the same manner.
<Example 5>
As shown in FIG. 35(e), a pouch was produced in the same manner as in Example 1, except that the value of A was 9 mm, and evaluated in the same manner.

<Comparative Example 1>
As shown in FIG. 35(f), a pouch was produced in the same manner as in Example 1, except that the value of A was 10 mm, and evaluated in the same manner. The above results are summarized in FIG.

From the results of FIG. 36, the superiority of the microwave oven cooking pouch according to the present invention could be confirmed.

FIG. 37 is a schematic plan view showing one embodiment of the pouch for microwave cooking 501 according to the present invention, and FIG. 38 is a schematic plan view showing an unsealed state of the pouch for microwave cooking shown in FIG. It is a diagram. Moreover, FIG. 40 is a cross-sectional schematic diagram showing an example of the layer structure of the laminate 520 that constitutes the pouch for microwave cooking 501 according to the present invention.

The pouch 501 for microwave cooking according to the present invention includes two laminates 520 having at least a base material layer 521 and a sealant layer 528, that is, the sealant layers of the surface laminate 506 and the back laminate 507 are opposed to each other, and In addition, a bottom tape 508 having at least a base layer 521 and a sealant layer 528 is folded in half so that the sealant layer 528 faces outward, and the periphery is heat-sealed to form a standing pouch.

One of the top seal portion 502 and the side seal portion 503 is heat-sealed, and the other side seal portion 503 is a filling opening 509 partially protruding from the side seal portion. After being filled with the content Y, it is heat-sealed to form a filling seal portion 505 . The other side of the side seal portion 3 corresponds to the inner portion 211B of the first seal portion 211 and the inner portion 212B of the second seal portion 212 of the first embodiment. The filling opening 509 corresponds to the side passage portion 60 of the first embodiment. The fill seal portion 505 corresponds to the side closure seal portion 300 of the first embodiment.

In this pouch 501 for microwave cooking, the distance A by which the filling seal portion 505 protrudes from the side seal portion 503 must be in the range of 0 mm≦A≦10 mm (see FIG. 37). If A is not within this range, when the pouch 501 filled with the content Y is heated in a microwave oven, the pouch will buckle in the vicinity of the filling seal portion 505, and the entire pouch will tilt, and in some cases, the content will be lost. It may spill.

Further, as shown in FIG. 38, when the pouch 501 is stood on the floor surface X with the bottom tape 508 downward, the distance between the floor surface X on which the pouch 501 stands and the liquid surface Y1 of the contained contents Y is H Assuming that the distance between the floor surface X on which the pouch 501 stands and the floor surface side edge 591 of the filling opening 509 is _H0 , the distance H must be smaller than or equal to the distance _H0 . In other words, when the content Y is filled, the amount of the content Y must not exceed the floor surface side edge 591 of the filling opening 509 . As can be seen from the examples described later, even when the distance A by which the filling seal portion 505 protrudes from the side seal portion 503 is in the range of 0 mm ≤ A ≤ 10 mm, the distance H is greater than the distance H ₀ , and therefore the liquid level exceeds the floor surface side edge 591 of the filling opening 509, when the pouch 501 filled with the content Y is heated in a microwave oven, the pouch is buckled near the filling sealing portion 505, and the whole may tilt or, in some cases, spill the contents.

On the other hand, when the distance A is in the range of 0 mm ≤ A ≤ 10 mm and the distance H is smaller than or equal to the distance H ₀ , when the pouch filled with the content Y is heated in a microwave oven, the filling This prevents the pouch 501 from buckling in the vicinity of the sealing portion 505, tilting the entire pouch, and possibly spilling the contents.

In the example shown in FIGS. 37 and 38, an opening start portion 510 and an opening guide line 511 starting from the opening start portion 510 are applied to the upper portion of the pouch. The unsealing guide line 511 is a half-cut line, which has the effect of bringing about smooth unsealing. A laser beam or a blade is used to form the half-cut lines.

(15th embodiment)
FIG. 39 is a schematic plan view showing a pouch 501 for microwave cooking according to the fifteenth embodiment. In this example, an opening guide line 511 with different shapes starting from an opening start portion 510 is applied to the upper portion of the pouch, and a fastener 512 is provided below the opening guide line. By doing so, when opening the fastener, the end portions of the laminated body on the front and back sides are displaced, so that it is easy to grasp by hand and opening is facilitated.

In addition to this, although not shown, a steam release mechanism may be provided in addition to the fastener. By doing so, it is possible to safely release the water vapor that is generated when ingredients are added after the package is opened, the zipper is closed, and the package is heated in a microwave oven. Such a vapor release mechanism is described in Japanese Patent No. 5946780, for example.

The laminate that makes up the pouch will be explained. FIG. 40 is a schematic cross-sectional view showing an example of the layer structure of the laminate 520 that constitutes the pouch 501 for microwave cooking according to the present invention. In this example, a printed layer 522 is formed on the back surface of a substrate layer 521, and the printed substrate layer 521, a gas barrier layer 524, an intermediate layer 526, and a sealant layer 528 are composed of adhesive layers 523, 525, and 528, respectively. 527.

The base material layer 521 and the sealant layer 528 are essential, and other layers can be omitted or have two or more roles. For example, if a gas-barrier synthetic resin film is used as the intermediate layer, the gas-barrier layer can be omitted. Also, if an inorganic oxide deposition film is used as the substrate layer, it can also serve as a gas barrier layer.

As the base material layer 521, a synthetic resin film having printability is used because it often serves as a base material for printing. Examples include oriented polyethylene terephthalate (PET) resin film, oriented nylon film (ONy), and oriented polypropylene (OPP) resin film.

The intermediate layer 526 is often added for the purpose of improving the strength and stiffness of the laminate 520, and nylon film, PET film, PP film, etc. can be used.

As the sealant layer 528, a polyolefin resin is generally used. Specifically, low density polyethylene resin (LDPE), medium density polyethylene resin (MDPE), linear low density polyethylene resin (LLDPE), ethylene- Ethylene-based resins such as vinyl acetate copolymer (EVA), ethylene-α-olefin copolymer, ethylene-methacrylic acid resin copolymer, blend resin of polyethylene and polybutene, homopolypropylene resin (PP), propylene- Polypropylene resins such as ethylene random copolymers, propylene-ethylene block copolymers and propylene-α-olefin copolymers are used. In the case of the pouch for microwave cooking according to the present invention, it is desirable to use a polypropylene-based resin in consideration of heat resistance because it is assumed to be heated by a microwave oven.

A general dry lamination adhesive can be used as the adhesive used for laminating each layer. Hereinafter, the pouch for microwave cooking according to the present invention will be described more specifically based on examples.

(Example)
The present invention will now be explained with experimental data. For convenience of explanation, examples that correspond to the present invention and examples that do not correspond to the present invention are collectively referred to as examples without distinguishing between them.

A printed layer 522 was formed on the deposition surface of a polyethylene terephthalate resin film (GL film manufactured by Toppan Printing Co., Ltd.) having silicon dioxide deposited on the back surface as a base layer 521 . A laminated body 520 is obtained by using an oriented nylon film as the intermediate layer 526, using an unoriented polypropylene resin film as the sealant layer 528, and bonding them together using a dry lamination adhesive.

Using this laminate, a standing pouch 501 as shown in FIG. 41 was produced. FIG. 41 is similar to FIG. 38, but in FIG. 41 the dimensions of each portion of the pouch 501 used in the example are entered. The unit of dimension is "mm". When the pouch 501 is erected on the floor surface X with the bottom tape 508 downward, the distance _H0 between the floor surface X on which the pouch 501 stands and the floor surface side edge 591 of the filling opening 509 is 30 mm. .

Then, as shown in FIG. 41, this was filled with mapo tofu sauce and the filling opening 509 was sealed.
This experiment was conducted by variously changing the filling amount of the mapo tofu sauce and variously changing the distance A between the filling seal portion 505 and the side seal portion 503 .

The filling amount of the mapo tofu sauce is the amount between the floor surface X on which the pouch 501 stands and the liquid surface Y1 of the contained contents Y when the pouch 501 is stood on the floor surface X with the bottom tape 508 downward. The distance H is such that it is 25 mm, 30 mm, 33 mm and 35 mm, respectively. Since the distance _H0 is 30 mm, both are equal when the distance H is 30 mm. The distance H is smaller than the distance _H0 when the distance H is 25 mm. On the other hand, when the distance H is 33 mm or 35 mm, the distance H is larger than the distance _H0 and does not correspond to the present invention.

Also, the distances A between the filling seal portion 505 and the side seal portion 503 are 0 mm, 5 mm, 7 mm and 10 mm, respectively. When the distance A is 0 mm, the filling seal portion 505 overlaps the side seal portion 503, and the inner edge of the filling seal portion 505 and the inner edge of the side seal portion 503 match.

Then, these pouches were subjected to retort sterilization treatment at 120° C. for 30 minutes with the pouches 501 erected with the bottom tape 508 downward, and then the upper part was opened and 350 g of silken tofu (1 to 2 cm square diced) was obtained. was added and heated in a microwave oven at 600 W for 4 minutes, and the state was observed.

The evaluation criteria were as follows.
〇: The side seal part does not break, or the part above the step part does not break and the contents do not leak.
Δ: The pouch tilted, but the contents did not leak.
x: The pouch tilted and the contents leaked.

The above results are summarized in FIG.
The following can be understood from the results of FIG.
That is, the distance A by which the filling seal portion protrudes from the side seal portion is 10 mm or less, and the distance H is smaller than the distance _H0 . By setting the amount so as not to exceed the floor surface side edge 591 of the opening 509, even when the pouch filled with the content Y is heated in a microwave oven, the pouch is softened and crumbled, and the pouch is stuck to the side seal portion. It is possible to prevent the phenomenon of tilting towards.
