Description

  The present invention relates to a food-sealed storage bag packaging box for packaging a food-sealed storage bag in which a microwave-heatable food, for example, a cooked or semi-cooked food is sealed, and the food-sealed storage bag. The present invention relates to a food sealed container bag package accommodated in a packaging box.

  Today, various microwaveable foods, such as already cooked or semi-cooked foods, that are hermetically housed in microwave permeable bags (usually plastic bags) are on the market. When such a food sealed container bag is placed in a microwave oven and heated, the food in the bag is heated and steam is generated, so that the bag pressure is increased to prevent the bag from bursting. A pressure relief portion is formed.

  Generally, such a food-sealed bag containing food that can be heated in a microwave oven is housed and packaged in a packaging box for storage, transportation, display, display of various information by description, and the like.

  In addition, today, some sealed food storage bags contained in a packaging box can be placed in a microwave oven and heated together with the packaging box.

The following can be seen as such bags and boxes.
For the food-sealed storage bag, the pressure release part is provided in a portion near one of the end parts of the bag, and when heating the microwave oven, the bag end part with the pressure release part is positioned higher than the opposite end part. If the bag is tilted so that it is placed in the microwave oven, even if the pressure relief part is opened by heating, there is no risk that the bag contents will flow out of the pressure relief part opened and soil the microwave oven. It is what is said.

  On the other hand, the packaging box can be opened to expose the pressure release portion of the food-sealed storage bag, and a microwave oven can be formed by bending a portion of the opened box to form a support portion. The bag can be arranged in an inclined posture, and the bag can be arranged in the microwave oven together with the box in an inclined state in which the end portion having the pressure releasing portion is positioned higher than the other end portion.

  Such food-sealed storage bags and packaging boxes are usually stored, transported, displayed, sold, etc. in the form of food-sealed storage bag packages in which the food-sealed storage bags are stored in the packaging box.

  Such a food sealed container bag package is described in, for example, Japanese Patent Application Laid-Open No. 2003-170930 and Japanese Patent No. 4522778.

JP 2003-170930 A Japanese Patent No. 4522778

  However, depending on the packaging box to be used, a part of the opened packaging box moves in the restoring direction from the opened state, and as a result, the pressure-release part of the food-sealed packaging bag is relative to the other part of the bag, There is a risk that the bag contents will not be placed at a high enough to prevent the blowing of the contents of the bag. In some cases, the packaging box may be opened incorrectly so that the pressure-release portion of the food-sealed packaging bag is not placed at a high enough to prevent the bag contents from blowing out relative to other parts of the bag. Conceivable.

  In addition, according to the conventional food sealed container bag package described above, in a state where a part of the packaging box is opened so that the food sealed packaging bag can be placed and heated in the inclined position in the microwave oven together with the packaging box, The depressurized portion is exposed from the packaging box, and depending on the type, amount, degree of heating, etc. of the food, a part of the food may blow out from the unsealed depressurized portion and the inside of the microwave oven may be soiled.

This invention makes it the 1st subject to provide the packaging box which is the food sealed container bag packaging box for packaging the food sealed container bag which enclosed the foodstuff which can be microwave-heated, and has the following advantages.
(1) With a part of the packaging box opened, the opened part can be supported and placed in a tilted position in the microwave oven so that the part with the pressure relief part faces the part to be opened. If stored in the packaging box, the food-sealed packaging bag can be placed in a microwave oven and heated with the pressure relief portion inclined at a high position together with the packaging box with a part of the packaging box opened. The inclination posture can reduce the risk of a part of food being blown out from the pressure release portion.
(2) Even if the opening method is different from the recommended standard box opening state, depending on the opening method, depending on the opening method, the packaging box may be such that the portion with the pressure relief portion faces the opening portion. If the container is housed in the container, the food sealed container bag can be placed in the microwave oven by tilting the pressure relief part together with the packaging box at a high position with a part of the packaging box opened.

A second object of the present invention is to provide a food sealed container bag package in which a food sealed container bag that contains food that can be heated in a microwave oven is stored in a food sealed container bag packaging box, and has the following advantages. It is an issue.
(1) Open the food-sealed storage bag accommodated inside with the food-sealed storage bag packaging box partially opened, but with the pressure-release portion of the food-sealed packaging bag covered with the packaging box. The pressure relief part of the bag together with the packaging box can be arranged in a tilted posture at a high position in the microwave oven with the support portion being supported, thereby blowing out part of the food from the pressure relief part of the food sealed container bag, etc. The fear can be reduced and the food blowout around the packaging box can be suppressed.
(2) Even if the food sealed container bag packaging box is opened differently from the recommended standard box opening state, depending on the opening method, the food sealed container bag is still located at a higher position where the pressure relief part is located. In addition, the microwave oven can be safely heated in a state where the pressure release portion is covered with the packaging box.

  Moreover, this invention makes it the 3rd subject to provide the box original plate which can assemble and form the food-sealing accommodation bag packaging box which concerns on this invention.

In order to solve the first problem, the present invention provides:
A food-sealed storage bag packaging box for packaging a food-sealed storage bag containing a microwave-heatable food,
An upper wall, a left wall whose upper end is continuous with the left end of the upper wall, a right wall whose upper end is continuous with the right end of the upper wall, and a lower wall that is continuous with the lower ends of the left and right side walls and faces the upper wall. Including a wall, a front wall following the front end of each wall and a rear wall following the rear end, and exhibiting a flat shape in which the distance between the upper and lower walls is shorter than the distance between the left and right side walls and the distance between the front and rear walls,
The upper wall has an arcuate central rupture portion projecting toward the rear end side of the upper wall formed at a position closer to the upper end of the upper wall than an intermediate position between the front and rear ends of the upper wall, from the left end of the central rupture portion. The left breaking portion that extends to the left end of the upper wall, the right breaking portion that extends from the right end of the central breaking portion to the right end of the upper wall, and a portion closer to the front end of the upper wall than the central breaking portion. And having an upper wall bending part extending between the left and right breaking parts,
The left side wall has a left side wall breaking part extending in a vertical direction following the left breaking part of the upper wall,
The right side wall has a right side wall breaking part extending in a vertical direction following the right breaking part of the upper wall,
The lower wall provides a food sealed container bag packaging box having a lower wall folding part extending between lower ends of the left and right side wall breaking parts.

According to the food-sealed storage bag packaging box according to the present invention, the food-sealed storage bag can be accommodated inside the assembled and formed box.
According to the food sealed container bag packaging box according to the present invention, the central breaking portion can be broken by pushing the portion between the central breaking portion and the folding portion of the upper wall into the box with a finger, for example. Further, the pushing portion can be bent toward the inside of the box along the bending portion in accordance with the breaking operation.

  Further, by pulling up the portion bent toward the inner side of the box, the right and left breaking parts following the central breaking part and the right and left side breaking parts are also broken following the breaking of the central breaking part. In addition, a part of the packaging box can be opened by bending the front end portion of the lower wall downward along the lower wall bending portion.

At this time, in accordance with the recommended method of opening the packaging box, the front end of the lower wall is bent and rotated by about 180 degrees along the lower wall folding portion and is opened in a state of being stacked on the remaining lower wall (in this state) The packaging box can be placed in an inclined posture using the opened box portion as a support pillow.
Hereinafter, this recommended standard method of opening the packaging box is sometimes referred to as “standard opening”.

  The packaging box according to the present invention can be placed in an inclined posture in the microwave oven with the opened portion supported as described above. Therefore, if the food sealed container bag is accommodated in the packaging box so that the part with the pressure relief portion is located near the opening part, the food sealed container bag is packaged with a part of the packaging box opened. The pressure relief part together with the box can be inclined and placed in a microwave oven at a high position and heated, and the inclination posture can reduce the risk of a part of food being blown out from the pressure relief part.

The food-sealed container bag packaging box according to the present invention may be opened differently from the “standard opening” but with an expected opening method. For example, the following opening method can be illustrated.
The portion between the central breaking portion and the folding portion of the upper wall is pushed into the box so as to break the central breaking portion, and the pushing portion is moved along the folding portion along the folding portion with the breaking operation. Bending toward the left side, the right and left side breaking parts following the central breaking part following the breaking of the central breaking part, and also breaking the left and right side wall breaking parts, and the lower wall front bending part Fold it down along. However, at this time, the front end portion of the lower wall is bent and rotated by approximately 90 degrees along the lower wall bending portion. The packaging box is placed in an inclined posture using the box portion thus opened as a support pillow. Hereinafter, this opening may be referred to as “opening 90 degrees”.

  Even when opened in this manner, the portion between the center breaking portion and the folding portion of the upper wall is already folded along the upper wall folding portion, and the folded portion is opened. The return rotation of the opened box portion, which is located below the food sealed container bag protruding from the box, is prevented. Therefore, if the food-sealed storage bag is stored in the packaging box so that the portion with the pressure relief portion is located near the opening portion, even if the packaging box is partially opened as described above, The food-sealed storage bag can be placed in the microwave oven by tilting the pressure relief portion together with the packaging box at a high position.

  As an example of the upper wall folding part in the food sealed container bag packaging box according to the present invention, a cutting line penetrating and cutting through the upper wall and a creasing line are arranged in a line so as to be easily folded. Things can be mentioned.

As a further example of such a folding part,
Examples of cutting lines and folding scoring lines formed in a straight line, and cutting lines and folding scoring lines formed in a circular arc projecting toward the front end of the upper wall it can.

  In any case, when a plurality of the cutting lines are formed, a case where they are intermittently formed in a perforated manner can be exemplified. The folding scoring line may also be intermittently formed in a perforation-like manner, but it is continuous, but as a whole, the cutting line and the folding scoring line are arranged in a line. You may form so that it may exhibit. As such a mode, the case where a cutting line is formed along a continuous creasing line can be illustrated.

  The distance from the front end of the lower wall to the lower wall folding portion is that of the central breaking portion and the folding portion of the upper wall even when opening 90 degrees as described above when opening the box according to the present invention. An example can be given of a distance that can be positioned below the sealed food bag that protrudes from the opened packaging box, with the portion folded along the folding portion in between. As a specific example, a case where the distance from the front end of the lower wall to the lower wall bending portion is made equal to or longer than the distance from the front end of the upper wall to the upper wall bending portion can be mentioned.

As another example of the opening method different from the above-described standard opening method of the food sealed container bag packaging box according to the present invention, the following opening method is also conceivable.
That is, the portion between the central breaking portion and the folding portion of the upper wall is pushed into the box so as to break the central breaking portion, and the pushing portion is moved along the folding portion along with the breaking operation. Bending toward the inside of the box, or further opening the left and right breaking parts following the central breaking part following the breaking of the central breaking part of the upper wall, or further breaking the breaking part of the left and right side walls, This is an opening method in which the front end portion of the lower wall is not bent downward along the lower wall bending portion.
Hereinafter, this opening method is sometimes referred to as “flat opening”.

Even in such a way of opening, the lower wall bending portion is placed next so that the packaging box and the food-sealed storage bag accommodated therein take an inclined posture so that the pressure relief portion of the bag is placed at a high position. It may be formed as follows.
That is, the left side wall breaking part extends obliquely in the direction of the rear end and right side of the lower wall following the lower end of the left side wall breaking part, and the rear end of the lower wall following the lower end of the right side wall breaking part And a lower wall bending portion having a right inclined breaking portion extending obliquely in the direction of the left end and a central bending portion extending between the lower wall rear end side ends of the left and right inclined breaking portions. is there.

  According to this lower wall folding part, even when the packaging box according to the present invention is opened by the above-mentioned “flat opening” which is different from the standard opening method, the inner food sealed container bag is expanded by heating to the internal pressure. As the upper and lower walls of the packaging box are deformed to be rounded, the left and right breaking parts of the lower wall folding part are broken, so that the opened part of the packaging box is warped downward. In addition, the packaging box and the food-sealed storage bag accommodated in the packaging box can take an inclined posture so that the pressure release portion of the bag is placed at a high position.

  The central folding part of the lower wall folding part projects to the front end side of the lower wall and the rear end side of the lower wall so that it is easy to bend and is difficult to turn once restored. Inverted mountain-shaped cutting lines are alternately arranged in a zigzag pattern with the non-cutting hinge portion interposed between the adjacent mountain-shaped cutting lines and the inverted mountain-shaped cutting lines. Also good.

  When the food-sealed container bag packaging box according to the present invention is opened at the above-mentioned [90-degree opening], the outer surface of the front wall of the packaging box that becomes the lower end surface of the opened portion that supports the packaging box in an inclined posture is rounded. If it is tinged, the opened box portion will easily slide and rotate on the tray in the microwave oven, and the box posture may become unstable.

Therefore, the following may be performed to flatten the outer surface of the front wall.
The front wall has front flaps that are continuous with the front ends of the left and right side walls bent inward, respectively, on the left and right front flaps, on the front wall pieces that are continuous with the front end of the upper wall, and on the front ends of the lower wall. One of the continuous front wall pieces is bent and overlapped, and a pre-formed glue hole is overlapped on the one, and the other is bent and overlapped on the one and the front wall pieces , And the other front wall piece is also glued to the flap through the glue hole.

  Further, instead of or together with the flattening of the outer surface of the front wall, the front wall is a front wall piece that is continuous with the front end of the upper wall and a front wall piece that is continuous with the front end of the lower wall. The front wall pieces are bent and overlapped so that the other of the front wall pieces is overlaid on one of them and glued together, and the front wall piece continuous to the front end of the lower wall includes A protrusion that integrally protrudes from the front end of the lower wall is formed by being surrounded by a cutting line, and the protrusion is bent from the front end of the lower wall by bending the front wall piece continuous with the front end of the lower wall. You may make it protrude.

  The protrusions can be inclined so that the outer surface of the front wall takes a high position on the rear end side of the lower wall, thereby exhibiting an anti-slip function.

In order to solve the second problem, the present invention also provides the following food sealed container bag package.

Therefore, the food-sealed packaging bag accommodated inside the packaging box In a state where a part of the food sealed container bag packaging box is opened, the pressure relief part of the bag together with the packaging box can be arranged in an inclined posture at a high position in the microwave oven while supporting the opened part. It is possible to reduce the risk of a part of food being blown out from the pressure release part of the food hermetically sealed bag.

  In addition, the food-sealed storage bag package according to the present invention has the food-sealed storage bag in a state where a part of the food-sealed storage bag packaging box is opened, but the pressure-release portion of the food-sealed storage bag is covered with the packaging box. Since it can arrange | position in a microwave oven in the broken state, the foodstuff blow-off and scattering from the pressure release part of the food-sealing accommodation bag to the outer periphery of a packaging box can be suppressed.

  In addition, even if the food-sealed container bag packaging box is opened in a different way from the recommended standard box opening state, depending on how it is opened, the food-sealed container bag is still located at a higher position where the pressure relief part is located. In addition, the microwave oven can be safely heated in a state where the pressure release portion is covered with the packaging box.

  In this way, the packaging box 1 is formed, and the food sealed container bag 2 is accommodated therein during the packaging box formation process. At that time, as shown in FIG. 1, the bag 2 is arranged so that the front side 21 of the bag 2 is directed to the box front wall 15, and the pressure release part 25 is the breaking portions C 1, C 21, C 22 of the box upper wall 11. The side walls 12 and 13 are accommodated so as to be covered with the box portion on the box rear wall 16 side from the breaking portions C31 and C32 of the side wall 12 and the bending portion B2 of the lower wall 14.

The packaging box 1 will be further described. The breaking portion C1 of the upper wall 11 is formed by arranging cutting lines c11 penetrating through the upper wall 11 in a perforated manner in an arc shape.
Each of the breaking portions C21 and C22 of the upper wall 11 is formed by arranging cutting lines c20 penetrating the upper wall 11 at intervals and arranged in an arc shape that slightly swells toward the upper wall front end 111 side.
The bending portion B1 of the upper wall 11 is formed by alternately arranging cutting lines b1 and bending scoring lines b2 formed through the upper wall 11 in a straight line.
As shown in FIG. 5B, the bending portion B1 has a cutting line b1 formed in a perforation along a straight bending line b200, and the cutting line and the bending line are formed as a whole. The auxiliary lines may be formed so as to be arranged in a line.

As illustrated in FIG. 13A, the bending portion of the upper wall 11 has a cutting line b1 ′ formed through the upper wall 11 and a bending creasing line b2 ′ in a row, toward the upper wall front end 111 side. Bending portions B1 ′ formed by alternately arranging in an expanding arc shape may be used.
Further, as illustrated in FIG. 13B, the bending portion B1 ′ is formed by forming a cutting line b1 ′ in a perforated manner along a folding line b200 ′ that is continuous in an arc shape. The lines and the creasing lines may be formed so as to be arranged in a line.

  Each of the breaking portions C31 and C32 of the side walls 12 and 13 is formed by linearly and linearly arranging linear and Y-shaped cutting lines penetrating the side walls.

  In this example, the bending portion B2 of the lower wall 14 includes an inclined fracture portion b21 extending obliquely toward the rear end 142 and one side end 144 of the lower wall 14 following the lower end of the left side wall fracture portion C31. Following the lower end of the right side wall breaking portion C32, an inclined breaking portion b22 extending inclined toward the rear end 142 and the other side end 143 of the lower wall 14 is included. Furthermore, it has the center bending part b23 extended between the edge parts on the lower wall rear end 142 side of the right and left inclined fracture parts b21 and b22.

  The central bending portion b23 of the lower wall 14 is easy to bend and protrudes toward the lower wall rear end 142 and the mountain-shaped lower wall penetration cutting line x1 protruding toward the lower wall front end 141 so that it is difficult to return once bent. Are formed in a zigzag pattern in which the inverted through-hole-shaped lower wall through cutting lines x2 are alternately arranged, and the non-cutting hinge portions y are interposed between the adjacent cutting lines x1 and x2.

According to the food sealed container bag packaging box 1 described above, the food sealed container bag package 100 can be provided by assembling and forming the food sealed container bag 2 inside.
According to the box 1, as shown in FIG. 6, the central breaking portion C1 is broken by pushing the portion A between the central breaking portion C1 and the bending portion B1 of the upper wall 11 into the box with, for example, a finger. Can do. Further, the pushing portion A can be bent toward the inside of the box along the bending portion B1 in accordance with the breaking operation.

  Further, by pulling up the portion A bent toward the inner side of the box, the right and left breaking parts C21 and C22 following the central breaking part as shown in FIG. By breaking the breaking part C31 (glue margin breaking part 171) and C32 of the left and right side walls 12 and 13, the front end B of the lower wall 14 is bent downward along the lower wall folding part B2. A part P of the packaging box 1 can be opened.

At this time, according to the recommended way of opening the packaging box 1, the front end B of the lower wall 14 is bent and rotated approximately 180 degrees along the lower wall bending portion B2 as shown in FIG. The stacked box 1 can be opened in such a manner that it cannot be easily restored and rotated, and the opened box portion P can be used as a support pillow to stably place the packaging box 1 in an inclined posture. FIG. 8A is a perspective view of the package 100 in which a part P of the packaging box 1 is opened, and FIG. 8B is a diagram of the package 100 viewed from the front wall side of the box.
Hereinafter, the recommended opening method of the standard packaging box 1 is referred to as “standard opening”.

  The packaging box 1 can be disposed in an inclined posture in the microwave oven with the opened portion P as a support while the portion P is opened as described above. Accordingly, if the food sealed container bag 2 is accommodated in the packaging box 1 so that the part where the pressure relief part 25 is located is located near the part P to be opened, the bag 2 is opened with a part P of the packaging box opened. The pressure relief part 25 together with the packaging box 1 can be tilted at a high position and placed in a microwave oven to be heated, and the inclination posture can reduce the risk of food blowout from the pressure relief part 25.

Further, since the food sealing container 2 is covered with a box part other than the box part P in which the pressure release part 25 is opened, the outer periphery of the packaging box 1 from the pressure release part 25 of the food sealing container 2 is provided. The blowout and scattering of the food 10 can be suppressed.
As shown in FIG. 15, the open box portion P seems to have slid on the tray T in the microwave oven unless a bending portion for bending the portion A ′ corresponding to the portion A of the upper wall 11 is provided. In such a case, the portion A ′ does not interfere with the inner bag 2 or does not interfere strongly, so that the rotation can be easily returned, and the bag 2 may not be placed in a sufficiently inclined posture.

The packaging box 1 may be opened differently from the “standard opening” but with an expected opening. For example, the following opening method shown in FIG.
A portion A between the central breaking portion C1 and the folding portion B1 of the upper wall 11 is pushed into the box so as to break the central breaking portion, and the pushing portion A is bent along with the breaking operation. B1 is bent toward the inside of the box along with B1. Further, following the breaking of the center breaking portion C1, the left and right breaking portions C21 and C22, and the breaking portions C31 and C32 of the left and right side walls 12 and 13 are also broken. The front end B of 14 is bent downward along the lower wall bending portion B2. However, at this time, the front end portion B of the lower wall 14 is bent and rotated by approximately 90 degrees along the lower wall bending portion B2. The packaging box 1 and the bag 2 are placed in an inclined posture with the box portion P thus opened as a support pillow. Hereinafter, this opening method is referred to as “90 degree opening”.

  Even in the case of opening in this way, the portion A between the center breaking portion C1 and the bending portion B1 of the upper wall 11 has already been folded along the upper wall folding portion B1, and the bent portion The return rotation of the opened box portion is prevented when A is located below the bag 2 protruding from the opened packaging box 1 (see FIG. 9B). Therefore, if the bag 2 is accommodated in the box 1 so that the part where the pressure relief part 25 is located is located near the part P to be opened, the part P of the packaging box 1 is opened incompletely in this way. However, the bag 2 can be placed in the microwave oven by tilting the pressure relief part 25 together with the packaging box 1 at a high position.

  In this example, the distance from the front end 141 of the lower wall 14 to the lower wall bending portion B2 is such that the center breaking portion C1 and the bending portion B1 of the upper wall 11 are bent even when “90 degrees open” as described above. It is set as the distance which can be located under the food sealed container bag 2 which protrudes from the packaging box 1 in which the part A folded along the part for bending in the middle is opened. As a specific example, the distance from the front end 141 of the lower wall 14 to the lower wall bending portion B2 (in this example, more precisely, the distance from the front end 111 of the upper wall 11 to the hinge portion y of the central bending portion b23) The distance is about the same as or longer than the distance to B1.

As another example of how to open the packaging box 1 different from the above-described standard opening method, the following opening method shown in FIG.
That is, the central breaking portion C1 is broken by pushing the portion A between the central breaking portion C1 and the bending portion B1 of the upper wall 11 into the box with a finger, and the pushing portion A is used for the breaking operation. At the same time, it is bent toward the inside of the box along the bending portion B1, or further, the left and right breaking portions C21 and C22 are opened following the breaking of the central breaking portion C1 of the upper wall 11, or the left and right side walls 12 and 13 are further opened. The breaking portions C31 and C32 are also broken, but the front end B of the lower wall 14 is not opened downward along the lower wall bending portion B2.
Hereinafter, this opening method is referred to as “flat opening”.

Even when the packaging box 1 is opened in such a manner, the packaging box 1 and the bag 2 accommodated in the packaging box 1 can take an inclined posture so that the pressure release portion 25 of the bag is placed at a high position.
That is, left and right inclined fracture parts b21, b22 are formed in the lower wall bending part B2, and the inner bag 2 is expanded by internal pressure by heating, so that the upper wall 11 and the lower wall 14 of the packaging box 1 are rounded. As shown in FIG. 10B, the inclined breaking parts b21 and b22 are broken as shown in FIG. 10B, whereby the opened portion P of the packaging box 1 warps downward, and the packaging box 1 and the bag 2 are The inclined posture can be taken so that the pressure release portion 25 of the bag is placed at a high position.

  As another opening method different from the above-described standard opening method of the packaging box 1, the opening method shown in FIG. 11 is also conceivable. 11 is an example in which the box 1 is opened by breaking the bending portion B2 of the lower wall 14 instead of opening from the breaking portion of the upper wall 11.

  Even in such a way of opening, as the inner bag 2 expands with internal pressure by heating and the upper wall 11 and the lower wall 14 of the box 1 are deformed to be rounded, the box 1 as shown in FIG. The opened portion P ′ is warped, so that the box 1 and the bag 2 accommodated in the box 1 can take an inclined posture so that the pressure release portion 25 of the bag is placed at a high position.

  By the way, the front wall 15 of the packaging box 1 bends inward the front flaps 121 and 131 that are continuous to the front ends of the left and right side walls 12 and 13, respectively, If the front wall piece 152 that is continuous with the front end of the lower wall is bent and overlapped and the front wall pieces 151 and 152 are merely glued, the front wall 15 may be rounded so that the front wall 15 bulges out ( (See FIG. 12C).

  Then, when the box 1 is “opened 90 degrees” as shown in FIG. 12C, the outer surface S1 of the front wall 15 of the packaging box that becomes the lower end surface of the opened portion P that supports the packaging box 1 in an inclined posture is a microwave oven. There is a possibility that the box will become unstable by slipping on the inner tray T and returning and turning easily.

  Therefore, the following may be performed to flatten the outer surface S1 of the front wall 15. That is, as shown in FIG. 12 (A), the front flaps 121 and 131 that are continuous with the front ends of the left and right side walls 12 and 13 are bent inward, respectively, on the left and right front flaps, on the front end 111 of the upper wall 11. One piece (151 in this example) of the continuous front wall piece 151 and the front wall piece 152 continuous to the front end 141 of the lower wall 14 is bent and overlapped, and the glue previously formed on the one 151 The through hole h is overlapped, the other piece 152 is bent and overlapped on the one piece 151, the two front wall pieces are bonded to each other with glue G, and the front wall piece 152 is passed through the glue through hole h. The flaps 121 and 131 may be glued. In this way, as shown in FIG. 12 (B), the outer surface S1 of the packaging box front wall 15 which becomes the lower end surface of the opened portion P that supports the packaging box 1 in an inclined posture is flattened, so that the inside of the microwave oven. The box posture is stabilized on the tray T.

  Further, instead of or along with such flattening of the outer surface of the front wall, the following may be performed. That is, as shown in FIG. 14, the front wall 15 includes a front wall piece 151 continuous to the front end 111 of the upper wall 11 and a front wall piece 152 continuous to the front end 141 of the lower wall 14. The pieces 151 and 152 are bent and overlapped so that the other 152 is overlaid on the one 151 and glued to each other, and the front wall piece 152 continuous with the front end 141 of the lower wall 14 is connected to the front wall 141 from the lower wall front end 141. The integrally projecting protrusion 1520 may be formed by being surrounded by a cutting line, and the protrusion 1520 may protrude from the lower wall front end 141 by bending the front wall piece 152 to the front wall piece 151.

  The protrusion 1520 can be disposed on the tray in the microwave oven so that the front wall outer surface S1 takes a high position on the rear end side of the lower wall, and exhibits an anti-slip function.

  Although it is not necessary to do so, the package 100 described above may be displayed, sold, or the like with the lower wall 14 facing the front.

  The present invention provides a food-sealed storage bag packaging box for packaging a food-sealed storage bag in which food that can be heated in a microwave oven is sealed, and a food-sealed storage bag package in which the food-sealed storage bag is stored in the food-sealed storage bag packaging box. Can be used to provide.
