  By the way, since the retort pouch food described in Patent Document 1 described above is sealed by closing a zipper provided in the vicinity of the opening after the ingredients are put into the pouch, it is used together with a seasoning liquid (such as sauce or soup). The pressure in the pouch rises due to the steam generated when the utensil is cooked in a microwave oven or the like. Therefore, in this retort pouch food, a steam hole for releasing steam to the pouch is formed. Thereby, even if the pressure in the pouch is increased by the steam generated during cooking, the steam is released from the steam hole, so that the pressure in the pouch is not increased more than necessary.

  However, the conventional retort pouch food described above has a complicated structure because it must be provided with a zipper and a steam hole in the pouch, making it difficult to manufacture and increasing the cost.

  The present invention has been made in view of such circumstances, and with a simpler configuration, it is possible to heat-cook the additional contents such as tools put into the opened flexible package together with the original contents. A flexible packaged product that can be made is provided.

A flexible packaged product according to the present invention is a flexible packaged product that is packed and sealed in a flexible package in which the contents can stand on its own. A pair of upper and lower locking portions that are formed on at least one of both side portions and lock each other, and the flexible packaging body includes an upper locking portion of the pair of upper and lower locking portions. And an opening guide portion for guiding the position between the lower locking portion and the lower locking portion to be opened in the width direction, and the flexible packaging bag has a first sheet and a second sheet facing each other. The opening guide part guides the opening of the first sheet or the second sheet by tearing in the width direction, and is opened according to the opening guide part. The package body is bent so that the pair of upper and lower locking portions can be locked to each other.

  With such a configuration, after the additional material is put into the self-supporting flexible packaging body that is opened according to the opening guide portion, the flexible packaging body is bent, and the pair of upper and lower locking portions are locked to each other. As a result, the folded state of the self-supporting flexible package can be maintained. The steam generated when cooking the original contents and additional items in the flexible package in a state of being bent in a self-standing manner with a microwave oven or the like is released by folding the flexible package. Although it becomes difficult, it is discharged from the opened portion through the folded portion.

And according to an opening guidance | induction part, it can open so that either one of the 1st sheet | seat and 2nd sheet | seat which a flexible packaging body may face may be torn in the width direction.

Further, since the flexible packaging body is opened so that either the opposing first sheet or second sheet of the flexible packaging body is torn at a position between the pair of upper and lower engaging portions, the pair of upper and lower engaging portions are mutually connected. Therefore, the opened flexible packaging body can be easily folded at a position between the pair of upper and lower locking portions.

  Further, in the flexible packaged product according to the present invention, the pair of upper and lower engaging portions can be cut and raised portions and hole portions into which the cut and raised portions are fitted.

  According to such a configuration, the folded state of the flexible packaging body is maintained by folding the flexible packaging body and engaging the cut and raised portions with each other so as to fit into the hole portions. become.

  Furthermore, in the flexible packaged product according to the present invention, each of the pair of upper and lower engaging portions is formed by cutting an outer cut formed obliquely from the outermost edge of the both side portions, and upward from the outer cut. It can be set as the notch part which consists of an inner notch following.

  With such a configuration, the flexible packaging body is folded, and the upper cutting portion and the lower cutting portion are inserted and locked to each other, whereby the flexible packaging body is folded. Will be maintained.

  According to the flexible packaged product according to the present invention, a pair of upper and lower latches are opened by adding an additional material into the self-supporting flexible package that is opened according to the opening guide mark and then bending the flexible package. By locking the parts to each other, the folded state of the self-supporting flexible package can be maintained. Therefore, it is possible to heat and cook the additionals put into the opened flexible packaging together with the original contents with a simpler configuration without providing a zipper or a steam hole as in the prior art.

  The flexible packaged product according to the first embodiment of the present invention is configured as shown in FIG. This flexible packaged product is a retort pouch food product in which a pouch (flexible package) is filled with a seasoning liquid such as sauce or juice and sealed.

  In FIG. 1, the retort pouch food 10 has a structure in which a pouch 14 with a bottom is filled with a fluid content N such as a seasoning liquid and sealed to be self-supporting. For example, the pouch 14 is formed in a bag shape by heat-sealing the peripheral portions of a front sheet 11, a back sheet 12, and a sheet (not shown) constituting the bottom part made of a multilayer resin. By this heat sealing process, a lower edge seal portion 131, side seal portions 132 and 133, and an upper edge seal portion 134 are formed around the bag-like pouch 14. The retort pouch food 10 can be self-supporting with the lower edge seal portion 131 of the pouch 14 as a foot portion.

  One side seal portion 132 of the pouch 14 is formed with a substantially U-shaped cut-and-raised portion 15a that can be raised from the bottom to the top at a position relatively close to the upper edge seal portion 134. A hole 16a is formed at a lower position away from the raising portion 15a by a predetermined length. The cut-and-raised portion 15a and the hole portion 16a constitute a pair of upper and lower locking portions that can be locked to each other by bending the pouch 14. Further, the side seal portion 133 on the opposite side of the pouch 14 is also formed with a cut-and-raised portion 15b and a hole portion 16b that constitute a pair of upper and lower engaging portions in the same positional relationship.

  A notch 151 is formed at a predetermined position between the cut and raised portion 15 a of the outer edge of the one side seal portion 132 and the upper edge seal portion 134 in the pouch 14, and the outer edge of the opposite side seal portion 133 is formed. A notch 152 is also formed at the same position. These notch portions 151 and 152 are opening guide portions for guiding the pouch 14 to be opened in the width direction from this portion, and along any of the notch portions 151 and 152 along the upper edge seal portion 132 ( The pouch 14 can be opened by tearing.

  The retort pouch food 10 described above is used as follows.

  The pouch 14 is torn along the upper edge seal portion 134 from one of the notches 151 and 152 formed in the side seal portions 132 and 133, and is opened as shown in FIG. As a result, the pouch 14 containing the content N such as seasoning liquid is cut off at the upper part from the tearing position, and the opening 150 is formed. In this state, a tool such as a meat lump (additional material S) is put into the self-supporting pouch 14 from the opening 150. Then, the contents N such as the seasoning liquid originally added to the pouch 14 and the additional material S such as a newly added ingredient are shaken by, for example, shaking the pouch 14 with the end portion where the opening 150 is formed. Are mixed together.

  Next, after removing air from the inside of the pouch 14 so as to press the front sheet 11 and the back sheet 12, the upper portions of the upper and lower cut-out portions 15a, 15b and the central portions of the hole portions 16a, 16 are Wrapped. Then, as shown in FIG. 3, the cut-and-raised portions 15a and 15b are raised from the side seal portions 132 and 133 and fitted into the holes 16a and 16b. Then, the folded back portion of the pouch 14 is displaced upward by the restoring force of the folded pouch 14, and the root portions of the cut and raised portions 15a and 15b and the side seal portions 132 and 133 in the vicinity thereof are separated. The cut-and-raised portions 15a and 15b and the hole portions 16a and 16b are engaged with each other so as to sandwich the edge portions of the hole portions 16a and 16b. Thereby, the pouch 14 maintains the bent state as shown in FIG.

  In this state (see FIG. 3), the contents N and the additional material S mixed in the pouch 14 are cooked by a microwave oven or the like. At this time, the steam generated in the pouch 14 does not easily pass through the bent portion, and does not easily exit from the opening 150 facing downward. However, when the pressure in the pouch 14 is increased to some extent, the steam generated inside the pouch 14 is expelled through the bent portion and is discharged from the opening 150 facing downward. As a result, the inside of the pouch 14 is maintained at an appropriate temperature and pressure, and the original mixed content N and additional material S are cooked by heating.

  According to the above-described retort pouch food product 10 which is a flexible packaged product according to the first embodiment of the present invention, the pouch 14 is opened by being cut from one of the notches 151 and 152 and is self-supporting. After the additional material S is put in, the pouch 14 is bent and the pair of upper and lower cut-and-raised portions 15a and 15b and the holes 16a and 16b are locked to each other, whereby the opened and self-supporting pouch 14 is bent. It will be possible to hold the state. Therefore, as in the prior art, without adding a zipper or a steam hole, it is possible to heat and cook the additional material S placed in the opened pouch 14 together with the original contents N by a microwave oven or the like with a simple configuration. become able to.

  The flexible packaged product according to the second embodiment of the present invention is configured as shown in FIG. This flexible packaged product is also a retort pouch food product in which a pouch (flexible package) is preliminarily filled with contents such as seasoning liquid and sealed. In FIG. 4, the same reference numerals are assigned to the same parts as those shown in FIG.

At that time, when the internal pressure rises due to the steam generated in the pouch 14, the folded portion 32 expands as shown in FIG. 15, and the front sheet 11 side of the pouch 14 greatly expands. Therefore, the volume in the pouch 14 increases, and even when a relatively large amount of the additive S is added, cooking can be performed without spilling. Further, when the front sheet 11 side extends greatly, the folding back to the back sheet 12 side becomes more reliable. The content N and the additional material S can be cooked while keeping the pressure in the pouch 14 relatively high. In addition, when the user throws in the additional material S, the folded portion 32 may be widened.

  Further, according to the retort pouch food 10 shown in FIGS. 12 and 13 as the flexible packaged product according to the sixth embodiment of the present invention, the first to fifth embodiments described above are used. As in the case of the flexible stuffed product, the addition S put in the opened pouch 14 is put together with the original contents N with a microwave oven or the like with a simple configuration without providing a zipper or a steam hole. Of course, it becomes possible to cook by heating.

  The flexible packaged product according to the seventh embodiment of the present invention is configured as shown in FIGS. 16 and 17. This flexible packaged product is also a retort pouch food product in which a pouch (flexible package) is preliminarily filled with contents such as seasoning liquid and sealed. 16 and 17, the same reference numerals are given to the same parts as those shown in FIG.

  In the retort pouch food 10 shown in FIGS. 16 and 17, the front sheet 11, the back sheet 12, and the bottom are configured in the same manner as the retort pouch food 10 (see FIGS. 12 and 13) according to the sixth embodiment described above. The pouch 14 which can be self-supported in the bag shape is formed by stacking the sheets 31 to be stacked and sealing the surrounding portion. The side seal portions 132 and 133 of the pouch 14 are formed with cut and raised portions 15a and 15b, holes 16a and 16b, and notches 151 and 152 as opening guide portions. Further, a folded portion 33 is formed at a predetermined portion of the front sheet 11 by folding the front sheet 11 in the vertical direction and folding it back at two locations, the upper side and the lower side. A similar folded portion 34 is formed at a position facing the folded portion 34.

  In such a retort pouch food product 10, the pouch 14 is torn from one of the notches 151 and 152 (opening guide portion), opened as shown in FIG. 18, and from the opening 150 formed by this opening. The additional material S is put into the self-supporting pouch 14 and mixed with the original content N. Then, the upper portions of the upper and lower center portions of the cut and raised portions 15a and 15b and the hole portions 16a and 16 are folded, for example, with the sheet 12 inside, and the cut portions are cut in the same manner as shown in FIG. The raised portions 15a, 15b and the holes 16a, 16b are locked to each other, and the folded state of the pouch 14 is maintained (see FIG. 3).

  In this state, the original content N and the additional material S mixed in the pouch 14 are cooked by an electromagnetic range or the like. At that time, when the internal pressure rises due to the steam generated in the pouch 14, the folded portion 33 on the front sheet 11 side and the folded portion 34 on the back sheet 12 side expand as shown in FIG. Increase in volume. Thereby, even if a relatively large amount of the additive S is put into the pouch 14, it can be cooked without being blown out. Note that when the user inserts the additional material S, the folded portions 33 and 34 may be widened.

  Moreover, according to the retort pouch food 10 shown in FIG. 16 and FIG. 17 as the flexible packaged product according to the seventh embodiment of the present invention, the first to sixth embodiments described above are used. As in the case of the flexible stuffed product, the addition S put in the opened pouch 14 is put together with the original contents N with a microwave oven or the like with a simple configuration without providing a zipper or a steam hole. Of course, it becomes possible to cook by heating.

  In each of the above-described embodiments, the cut-and-raised portion and the hole as a pair of upper and lower engaging portions are formed on both side seal portions 132 and 133, respectively. The locking portion may be formed on only one of the side seal portions 132 and 133. In this case, since the folded pouch 14 is in a state in which only one side seal portion 132 (133) is fitted, the user can more reliably secure the folded state of the pouch 14 by folding himself / herself. Can be maintained.

  In addition, the contents N such as the seasoning liquid are put in, and the pouch 14 that can stand on its own is opened, and the contents of the pouch 14 are turned up with a microwave oven or the like after the additional part S such as a tool is turned on. From the viewpoint of cooking the additional material S together with N, a simpler method as shown in FIG. 20 is conceivable. In the retort pouch 10 shown in FIG. 20, instead of mutually locking the folded portions as described above with a pair of upper and lower locking portions, both the side seal portions 132 in a state where the pouch 14 is bent. Can be fixed with the tapes 41 and 43, and the tape 42 can be pasted from the back sheet 12 to the front sheet 11 with the portion where the opening 15 is formed as a boundary.

  As described above, the flexible packaged product according to the present invention has a simpler structure and heats the original contents with additional items such as tools put into the opened flexible package. It has the effect that it can be cooked, and is useful as a flexible packaged product that is formed by filling a sealed flexible package such as a pouch and sealing it.
