JP 2003-170930 A

  However, in the conventional microwave oven boxed pouch (packaging bag) having the above-described structure, the pouch is caught inside the tip portion when the tip portion of the decorative box is rotated, and the pouch can be heated. It is difficult to set the cosmetic box so that

  This invention is made | formed in view of such a situation, and provides the packaging bag with a microwave oven box which can be heated with a microwave oven more easily.

  The microwaveable boxed packaging bag according to the present invention is a microwaveable boxed packaging bag having a structure in which a packaging bag for a microwave oven in which a steam vent portion is formed at an edge portion is housed in a box body, the box body Has a top surface and a bottom surface that face each other, and a side surface that continues to the edge of the top surface and the bottom surface, a lid portion is formed on the top surface so that it can be opened, It is configured to be folded in two and stored in the box so that the one side portion where the vapor venting portion is formed by the two folds is opposed to the top surface and the other side portion is opposed to the bottom surface.

  With such a configuration, when the packaging bag stored in the box with the lid formed on the top surface opened is heated in a microwave oven, the contents of the packaging bag are heated and its internal pressure rises, The folded folded packaging bag expands due to its increased internal pressure. In the process, one side portion of the packaging bag in which the steam vent portion, which has been directed to the top surface by folding in two, is ridden on the side edge of the box. And when the internal pressure of a packaging bag exceeds predetermined pressure, a vapor | steam spouts from the steam vent part which climbs on a side edge and is in a comparatively high position, and can prevent the excessive internal pressure rise of a packaging bag. Moreover, since the steam vent is maintained at a relatively high position, the contents can be prevented from leaking from the steam vent.

  Further, in the microwaveable boxed packaging bag according to the present invention, the lid portion is structured to be separated from the top surface leaving a hinge portion that becomes a boundary with the side surface of the top surface, and is folded in half. The packaging bag can be configured to be housed in the box so that the bent portion faces the hinge portion side of the lid portion formed on the top surface.

  With such a configuration, the lid is opened with the boundary between the top surface and the side surface as a hinge portion. In this state, when the packaging bag stored in the box is heated with a microwave oven, the folded folded packaging bag is expanded due to the increase in its internal pressure, and a steam vent portion facing the top surface is formed. One side of the packaging bag is in a state of riding on the lid that continues from the side of the box via the hinge. Since the part where the steam vent part of the packaging bag that has expanded due to the increase in internal pressure is supported by the lid, the posture of the packaging bag where the steam vent part is relatively high during heating is more stable Will be able to maintain

  Furthermore, in the microwaveable boxed packaging bag according to the present invention, the packaging bag is configured such that the one side portion where the steam vent is formed protrudes outward as the internal pressure increases. it can.

  With such a configuration, in a state where the portion where the steam vent portion of the expanded packaging bag is placed on the lid portion, the portion where the steam vent portion is formed further protrudes outward. As a result, the portion of the packaging bag where the steam vent is formed can be maintained at a higher position.

  Further, the microwaveable boxed packaging bag according to the present invention is a boxed packaging bag having a structure in which a packaging bag for a microwave oven in which a steam vent is formed at an edge is housed in the box, and the box Has a top surface and a bottom surface that face each other, and a side surface that continues to the edge of the top surface and the bottom surface, a lid portion is formed on the top surface so that it can be opened, It is folded in half, and the one side part where the steam vent part is formed by the two folds protrudes outward as the internal pressure rises, and the one side part where the steam vent is formed faces the bottom surface In addition, the other side portion is stored in the box body so as to face the top surface, and the folded side portion of the packaging bag that is folded in two faces the side surface of the box body that is expanded due to an increase in internal pressure. Removable part to form a notch area through which the packaging bag passes Configuration and made with.

  With such a configuration, the lid portion formed on the top surface is opened, and a portion corresponding to the notch region on the side surface is removed to form a notch region on the side surface. When the packaging bag housed in a box with the lid part opened and the side notched area was formed was heated in a microwave oven, the contents of the packaging bag were heated and the internal pressure increased, and was folded in two. The packaging bag expands as its internal pressure increases. In that process, the outer side of the box is formed through a notch region in which the one side part where the vapor vent part is formed by folding is on the bottom surface of the box and the other part facing the top side is formed on the side surface. Get out. Due to the increase in internal pressure in this state, the portion of the packaging bag where the steam vent is formed protrudes outward, and the expanded packaging bag is supported and inclined by the protruding portion. Further, the steam is ejected from the steam vent portion where the packaging bag is inclined and maintained at a relatively high position to prevent an excessive increase in the internal pressure of the packaging bag, and the contents are prevented from leaking.

According to the packaging bag for a microwave oven according to the present invention, the lid formed on the top surface of the box is opened, and the box containing the packaging bag is set in the microwave oven as it is, and the electronic By simply operating the range, the folded folded packaging bag is expanded by the increase in internal pressure, and the packaging bag is heated while the steam vent is maintained at a relatively high position. Heating by the range becomes possible.
In addition, since the packaging bag is folded in two and stored in the box, the storage efficiency can be increased and the package can be made compact, and can be displayed at a storefront, and can be easily carried.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  A microwave oven boxed pouch (packaging bag) according to a first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1 (a), the microwave oven boxed pouch is folded in two so that the microwave oven pouch 10 is divided into a first pouch portion 10a and a second pouch portion 10b. It is paid in. 2 (a) and 2 (b) as well as FIG. 1 (a), the box 20 has a top surface 21 and a bottom surface 22 that face each other, and a side surface that continues to the edges of the top surface 21 and the bottom surface 22 ( It has a rear side surface 23a, a front side surface 23b, a right side surface 23c, and a left side surface 23d), and has a flat rectangular parallelepiped shape. The top surface 21 is formed with perforations 25a and 25b extending forward from the boundary with the rear side surface 23a at both left and right end portions, and these perforations 25a and 25b extend from the top surface 21 to the front side surface 23b. It is extended. The perforations 25a and 25b make it easy to cut along the perforations 25a and 25b, and the portion sandwiched between the perforations 25a and 25b of the top surface 21 becomes the lid 211.

  The pouch 10 is basically a flat bag type, and a steam vent 11 is formed at the edge thereof. For example, as disclosed in Japanese Patent Application Laid-Open No. 2002-249176, the steam vent 11 has a structure (weakened part) that is sealed in a state in which the periphery of the hole is easily peeled off, and the internal pressure of the pouch 10 is When the limit is exceeded, steam is ejected from the steam vent 11. Further, a folded portion 12 is formed in the first pouch portion 10a where the steam vent portion 11 of the folded pouch 10 is formed. The folded portion 12 projects outward when the pouch 10 expands due to an increase in its internal pressure. The detailed structure of the folded portion 12 is disclosed in Japanese Patent Laid-Open No. 2006-62672.

  The folded pouch 10 has a first pouch portion 10a formed with the steam vent 11 facing the top surface 21 and the other second pouch portion 10b facing the bottom surface 22, and is folded in two. The portion (the boundary between the first pouch portion 10a and the second pouch portion) is housed in the box 20 so as to face the hinge portion 211a at the boundary with the rear side surface 23a of the lid portion 211 formed on the top surface 21. Yes.

  When heating the microwave oven box pouch having such a structure, first, the top surface 21 and the front side surface 23b of the box 20 are cut along the perforations 25a and 25b, and the boundary between the top surface 21 and the rear side surface 23a is cut. The lid 211 is cut off, leaving the hinge portion 211a. Thereby, as shown in FIGS. 3 and 4, the lid 211 is opened, and a large opening 212 is formed in the top surface 21. And the cover part 211 connected with the rear side surface 23a of the box 20 by the hinge part 211a maintains the state which inclined and stood up from the hinge part 211a.

  As shown in FIGS. 3 and 4, the pouch 10 has three steam vents 11a, 11b, and 11c formed on the edge thereof, but FIG. The steam vents 11a, 11b, and 11c are generally represented by a single steam vent 11 (the same applies to FIGS. 1 (b) and 1 (c)).

  In this way, when the box body 20 in which the folded pouch 10 is stored in the state where the lid portion 211 is opened is set in the microwave oven and the microwave oven is operated, the contents of the pouch 10 are heated. In the process, the internal pressure is increased by the generated steam, and the pouch 10 expands and expands as shown in FIG. 1 (b), gradually from the opening portion 212 formed on the top surface 21 of the box 20. It rises up. At that time, the folded portion 12 also expands and gradually protrudes outward.

  Further, when the contents of the pouch 10 are heated and the internal pressure is increased by the generated steam, as shown in FIGS. 1C, 5, and 6, the steam vent 11 of the pouch 10 protruding from the opening portion 212 ( 11a, 11b, 11c) are formed on the lid 211 (the first pouch portion 10a). At this time, the tip of the folded-back portion 12 in a protruding state abuts against the lid portion 211 to support the portion (first pouch portion 10a) where the steam vent 11 (11a, 11b, 11c) of the pouch 10 is formed. Therefore, the steam vent 11 (11a, 11b, 11c) is maintained at a higher position. When the internal pressure of the pouch 10 exceeds the limit, steam is ejected from the steam vent 11 (11a, 11b, 11c) maintained at a high position, and an excessive increase in the internal pressure of the pouch 10 is prevented.

  According to the microwave oven boxed pouch as described above, the lid 211 formed on the top surface 21 of the box body 20 is opened, and the box body 20 in which the pouch 10 is stored is set in the microwave oven in that state. By simply operating the microwave oven, the folded pouch 10 expands and expands due to an increase in internal pressure, and the steam vent 11 (11a, 11b, 11c) is maintained at a relatively high position. Is heated, so that it can be easily heated by a microwave oven.

  In particular, since the portion where the steam vent 11 (11a, 11b, 11c) of the expanded pouch 10 is formed is supported by the lid 211 that is inclined and rises from the hinge portion 211a, In addition, since the folded-back portion 12 that protrudes outward supports the portion (first pouch portion 10a) where the steam vent 11 (11a, 11b, 11c) is formed on the lid portion 211, The steam vent 11 (11a, 11b, 11c) can be maintained at a higher position, and steam is ejected from the steam vent 11 (11a, 11b, 11c) while reliably preventing leakage of contents. To be able to.

  In addition, since the pouch 10 with a microwave oven as described above is folded in two and stored in the box 20, the storage efficiency can be increased and the package can be made compact and can be displayed at a storefront. There are effects such as easy.

  Note that the lid portion 211 may be completely cut off from the top surface 21. Alternatively, the pouch 10 that is folded in half may be stored in the box 20 so that the bent portion faces the opposite side of the hinge portion 211a of the lid 211. In these cases, the part (first pouch part 10a) where the steam vents 11 (11a, 11b, 11c) are formed in the process in which the pouch 10 is expanded due to the increase in the internal pressure, the side surface ( In the former case, the pouch 10 rides on the edge of the rear side surface 23a, and in the latter case, the front side surface 23b), so that the pouch 10 is maintained with the steam vents 11 (11a, 11b, 11c) maintained at a relatively high position. Can be heated.

  In the above-described example, the folded portion 12 that protrudes outward is formed in the portion (first pouch portion 10a) where the steam vent 11 (11a, 11b, 11c) of the pouch 10 is formed. In particular, it is not necessary to form the folded portion 12 protruding outward in this way. Even in this case, when the pouch 10 folded in half is inflated and expanded, the portion where the steam release portion 11 (11a, 11b, 11c) is formed is covered with the hinge portion 211a of the lid portion 211. Since it gets on the part 211, the pouch 10 can be heated in a state where the steam venting part 11 (11a, 11b, 11c) is maintained at a relatively high position.

  Next, a microwave oven boxed pouch (packaging bag) according to a second embodiment of the present invention will be described with reference to FIGS. The microwave oven boxed pouch according to the second embodiment is the same as the above-described example in that the pouch 10 expands on the opposite side to the lid portion 213 of the box body 20 when heated in the microwave oven. Is different.

  As shown in FIG. 7 (a), the microwave oven boxed pouch has a folded pouch 10 in which a steam vent 11 is formed, contrary to the above-described example (see FIG. 1 (a)). The first pouch portion 10 a is placed in the box 20 so as to face the bottom surface 22 and the other second pouch portion 10 b faces the top surface 21. And the folding | returning part 12 is formed in the 1st pouch part 10a in which the steam release part 11 was formed, and the folding | returning part 12 is the state pressed against the bottom face 22 of the box 20. FIG.

  As shown in FIGS. 8A and 8B together with FIG. 7A, the box 20 has a top surface 21 and a bottom surface 22 that face each other, and a side surface that continues to the edges of the top surface 21 and the bottom surface 22 ( It has a rear side surface 23a, a front side surface 23b, a right side surface 23c, and a left side surface 23d), and has a flat rectangular parallelepiped shape. A perforation 26 is formed on the top surface 21 and the front side surface 23b. The perforation 26 extends forward from the boundary with the rear side surface 23a of one side end portion of the top surface 21 and wraps around the front side surface 23b. The perforation 26 extends along the lower edge of the front side surface 23b. 21 wraps around the other side end of 21 and reaches the rear side surface 23a. A portion sandwiched between perforations 26 formed at both right and left end portions of the top surface 21 is a lid portion 213, and a boundary between the lid portion 213 and the rear side surface 23a is a hinge portion 213a. Moreover, the part surrounded by the perforation 26 formed in the front side surface 23b becomes the removal part 213b.

  As described above, the pouch 10 folded in half and stored in the box 20 has a bent portion (the boundary between the first pouch portion 10a and the second pouch portion), contrary to the above-described example (see FIG. 1A). ) Is directed to the removal portion 213b on the opposite side of the hinge portion 213a of the lid portion 213, and the steam release portion 11 is directed to the hinge portion 213a of the lid portion 213.

  When heating a microwave oven box pouch having such a structure, first, the top surface 21 and the front side surface 23b of the box 20 are cut along the perforation 26 to remove the removal portion 213b from the front side surface 23b and The lid portion 213 is separated while leaving the hinge portion 213a that becomes the boundary between the surface 21 and the rear side surface 23a. As a result, as shown in FIG. 8 (pouch 10 is omitted in FIG. 8), lid portion 213 is opened to form large opening portion 214 on top surface 21, and removal portion 213b is formed on front side surface 23b. A notch region 215 is formed as a trace from which is removed.

  When the box 20 containing the folded pouch 10 is set in the microwave oven with the lid 213 opened and the cutout area 215 formed on the front side surface 23b, the microwave oven is operated. The contents of the pouch 10 are heated. In the process, the internal pressure is increased by the generated steam, and the pouch 10 expands and expands toward the front side surface 23b of the box 20 as shown in FIG. The portion (the first pouch portion 10 a) on which 12 is formed (the second pouch portion 10 b) is gradually raised from the opening portion 214 formed on the top surface 21 of the box 20. At that time, the folded portion 12 in contact with the bottom surface 22 of the box 20 also expands and gradually protrudes outward. As the folded portion 12 protrudes, the end portion of the pouch 10 on the side where the steam release portion 12 is formed gradually rises.

  Further, when the contents of the pouch 10 are heated and the internal pressure rises due to the generated steam, as shown in FIG. 7C, a portion where the steam vent 12 of the pouch 10 is formed (first pouch portion 10a) and The opposite side portion (second pouch portion 10b) goes out of the box body 20 through a cutout region 215 (see FIG. 7B) formed in the front side surface 23b of the box body 20. As a result, the expanded pouch 10 is in a state in which the end on the side where the steam release portion 12 is formed is raised by the protrusion of the folded portion 12 and is inclined to lie from the inside of the box body 20 to the outside thereof. When the internal pressure of the pouch 10 exceeds the limit, steam is ejected from the steam vent 11 maintained at a relatively high position, and an excessive increase in the internal pressure of the pouch 10 is prevented.

  According to such a boxed pouch for a microwave oven, the cover portion 213 formed on the top surface 21 is opened while removing the removal portion 213b formed on the front side surface 23b of the box body 20, and the pouch of the pouch is kept in that state. By simply setting the stored box 20 in a microwave oven and operating the microwave oven, the folded pouch 10 expands and expands due to an increase in internal pressure, and the protrusion of the folded portion 12 causes a steam venting portion. Since the pouch 10 is heated in an inclined state so that 11 is maintained at a relatively high position, heating by a microwave oven can be easily performed.

  In the above-described example, the removing unit 213b is integrated with the lid 213. However, the removing unit 123b may be removed separately from the lid 213. The lid 213 can also be completely cut off from the top surface 21.

  The size of the cutout region 215 formed on the front side surface 23b by removing the removal portion 213b is not particularly limited as long as the expanded pouch 10 is not prevented from coming out of the box 20. Specifically, it is preferable to set the notch region 215 (removal portion 213b) so that the pouch 10 inclined by the protrusion of the folded portion 12 is not caught on the edge of the front side surface 23b.

  The packaging bag for a microwave oven according to the present invention has an effect that it can be easily heated in a microwave oven, and a steam vent is formed at the edge so that heating in the microwave oven is possible. It is useful as a boxed packaging bag having a structure in which a packaging bag such as is packed in a box.
