Description

  The present invention relates to a packaging box for packaging a food-sealed packaging bag in which food that can be heated in a microwave oven, for example, a cooked or semi-cooked food, and the food-sealed packaging in which the food-sealed packaging bag is contained in the packaging box The present invention relates to a bag package. The invention further relates to a box original for providing the 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 the end of the bag with the pressure release part is positioned higher than the opposite end part for heating the microwave oven. 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 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, when a conventional food-sealed packaging bag package is placed in the microwave oven together with the packaging box in order to heat the contents of the food-sealed packaging bag in a microwave oven, the packaging box is simply opened and the electronic Rather than being placed in the range, the packaging box is opened at the designated packaging box site in accordance with the designated procedure, and a portion of the opened box is folded to serve as a support, and the food sealed container bag is depressurized. It must be placed in the microwave oven in an inclined state where the end with the part is located higher than the other end, and consumers who are not used to the work may be confused, and some consumers may feel annoyed It seems that there was.

  In addition, 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.

  The present invention is a food sealed container bag packaging box for packaging a food sealed container bag having a pressure relief portion opened by an internal pressure increase due to heating of the food product, wherein the food that can be heated in a microwave oven is sealed, The food sealed container can be placed in a microwave oven and the food in the bag can be heated in the microwave. At that time, the pre-designated packaging box is opened, but opened as before. It is not necessary to bend a part of the box and place it in a microwave oven in a tilted state as a support part, and yet can suppress the outflow of bag contents other than steam from the pressure release part of the bag to such an extent that it can be practically used, Alternatively, a first object is to provide a food sealed container bag packaging box that can be prevented and is convenient for consumers.

  Further, the present invention provides a food sealed container in which a food sealed container bag having a pressure relief portion opened by an increase in internal pressure due to heating of the food product is contained in a food sealed container bag packaging box. It is a bag package, and can be placed in a microwave oven while the food sealed container bag is stored in the food sealed container bag packaging box, and the food in the bag can be heated in a microwave oven. However, it is not necessary to fold a part of the opened box as in the prior art and place it in the microwave oven in a tilted state as a support part, and yet the steam from the pressure release part of the bag It is a second object to provide a food sealed and encased bag package that is convenient for consumers and can be suppressed or prevented to the extent that there is practically no spillage of other bag contents.

  Moreover, this invention makes it the 3rd subject to provide the box original plate which can assemble and form the food-sealed 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 having a pressure relief portion opened by an internal pressure increase due to heating of the food, wherein the food that can be heated by a microwave oven is hermetically sealed,
An upper wall, a left side wall having an upper end continuing to the left end of the upper wall, a right side wall having an upper end continuing to the right end of the upper wall, a lower wall following the lower ends of the left and right side walls, and facing the upper wall; It includes a front wall following the front end of the upper wall and the lower wall and a rear wall following the rear end, and exhibits 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 front wall includes an opening portion that can be opened so as to be located on the same plane as the upper wall;
An upper wall bending line extending in the front and rear end direction is formed at the center in the left and right direction of at least the front end of the upper wall,

Provide a storage bag packaging box.

In order to solve the second problem, the present invention
A food-sealed storage bag package in which a food-sealed storage bag containing food that can be heated in a microwave oven is stored in a food-sealed storage bag packaging box,
The food-sealed storage bag is formed of a microwave-permeable film, contains food that can be heated in a microwave oven, and has a front side, a rear side facing the front side, and the front and back sides The peripheral part including the right and left side parts extending to is sealed and presents a flat shape, and a pressure relief part that is opened by an increase in internal pressure due to heating of the food is formed in a portion near the front side part,
The food sealed container bag packaging box is a packaging box according to the present invention,
The food sealed container bag provides a food sealed container bag package in which the front side portion is directed to the front wall side of the packaging box and is accommodated in the packaging box.

  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. At this time, the bag portion having the pressure release portion can be accommodated toward the front wall side.

  According to the food sealed container bag packaging box of the present invention, the opening portion of the front wall is opened so as to be substantially flush with the upper wall, and the upper wall folding line and the front wall are opened. As a state in which the folding line of the part continues substantially linearly, the food sealed container bag as described above is placed inside, placed on the tray in the microwave oven with the upper wall facing downward, and heating can be started. it can. Thus, the food in the food sealed container bag is heated, and the bag is expanded by the vapor pressure generated thereby.

  Due to the expansion of the bag, the upper wall (the upper wall disposed downward with a folding line in the microwave oven) and the lower wall (the lower wall disposed upward in the microwave oven) are opposed to each other. A tensile force is applied in the vertical direction, so that the upper wall and the lower wall begin to deform so as to gradually expand toward the outside of the box.

  At this time, the upper wall side of the packaging box in the straight line and the folding line of the upper wall and the folding line of the opening part are convex upward, and the lower wall side where such a folding line is not formed is upwardly convex. The bag is also deformed to have a larger downward convex shape than the upper surface side in the microwave oven, and the bag also expands to have a larger downward convex shape on the lower surface side with less box resistance than the upper surface side in the microwave oven.

  Due to the expansion of the food-sealed storage bag, the fluid in the bag is stored below the pressure release part, and even if the pressure release part is opened due to an increase in the pressure in the bag, it leaks from the pressure release part. Suppressed or prevented to a practical extent.

  Thus, according to the packaging box according to the present invention, it is possible to heat the food in the bag by placing it in the microwave oven while containing the sealed food packaging bag. It is not necessary to fold a part of the opened box in the conventional manner and place it in the microwave oven in a tilted state as a support part, but still the bag contents other than the steam from the pressure release part of the bag The outflow can be suppressed or prevented to a practical extent.

  Further, according to the food sealed container bag packaging body according to the present invention, since the packaging box according to the present invention is adopted as the food sealed container bag packaging box, the front wall portion of the box is opened in the same manner as described above, and the upper wall Is placed on the tray in the microwave oven, and when heating is started, the food in the food sealed container bag is heated, and the bag expands due to the vapor pressure generated thereby, so that the upper wall side of the packaging box is Further, the bag is deformed into a downwardly convex shape that is larger than the lower wall side, and the bag also expands in a downwardly convex shape on the lower surface side with less box resistance on the lower surface side than the upper surface side in the microwave oven.

  Due to the expansion of the food-sealed storage bag, the fluid in the bag is stored below the pressure release part, and even if the pressure release part is opened due to an increase in the pressure in the bag, it leaks from the pressure release part. Suppressed or prevented to a practical extent.

  Thus, according to the package according to the present invention, it is possible to heat the food in the bag while placing the food sealed container bag in the food sealed container bag packaging box in the microwave oven, The packaging box is opened in advance at the front wall portion, but it is not necessary to bend the portion of the opened box as in the prior art and place it in a microwave oven in a tilted state as a support portion, yet from the pressure relief portion of the bag The outflow of the bag contents other than the steam can be suppressed or prevented to a practical extent.

Examples of the packaging box according to the present invention include the following.
The front wall includes a first front wall piece following the front end of the upper wall and a second front wall piece following the front end of the lower wall, and the second front wall piece is located at the center in the left-right direction. A pair of left and right breaking lines extending from a boundary line with the lower wall to a free end of the second front wall piece opposite to the boundary line, and a second front wall piece between the pair of left and right breaking lines A breaking line for opening the box over the line end on the boundary line side with the lower wall of the pair of left and right breaking lines, the folding line for folding the box is adjacent to the boundary line and the boundary line It is formed on at least one of the front end portions of the lower wall,
The first front wall piece is laminated and adhered on the second front wall piece,
For the first front wall piece, the first front wall piece overlaps the second front wall piece bending line in a state where the first front wall piece is superimposed on the second front wall piece. A line is formed,
When the first front wall piece bending line is opened and arranged on the same plane as the upper wall, the first front wall piece bending line is a bending line that follows the upper wall bending line linearly; A portion sandwiched between the pair of left and right breaking lines of the first front wall piece and the second front wall piece is a packaging box that provides the opening portion of the front wall.

  According to this packaging box, the breaking line straddling the line end on the boundary line side with the lower wall of the pair of right and left breaking lines of the second front wall piece constituting the front wall is for opening the box. This is a breaking line.

  The packaging box, for example, by placing a finger on the break line for starting opening the box, for example, by pulling the first front wall piece, which is laminated and adhered on the second front wall piece, in the opening direction, The first front wall piece can be opened.

  At this time, while rupturing the pair of left and right breaking lines of the second front wall piece, the center portion of the second front wall piece sandwiched between the pair of breaking lines is still bonded. It can be opened together with the first front wall piece.

  In this way, the first front wall piece is in a state in which deformation, deformation, and the like are suppressed while maintaining the double structure portion together with the second front wall piece sandwiched between the pair of breaking lines. Can be opened.

  Thus, in the state opened at the front wall portion, the second front wall piece bending line between the pair of left and right breaking lines of the second front wall piece portion opened together with the first front wall piece, The folding line of the first front wall piece formed so as to overlap this and the upper wall folding line formed on the upper wall are arranged in a straight line.

  With the box opened in this way, but with the food sealed container bag housed inside, it can be placed on the tray in the microwave oven with the upper wall facing downward, and heating can be started. Thus, the food in the food sealed container bag is heated, and the bag is expanded by the vapor pressure generated thereby.

  Due to the expansion of the bag, the upper wall (the upper wall disposed downward with a folding line in the microwave oven) and the lower wall (the lower wall disposed upward in the microwave oven) are opposed to each other. A tensile force is applied in the vertical direction, so that the upper wall and the lower wall begin to deform so as to gradually expand toward the outside of the box.

  At this time, the upper wall folding line of the upper wall, the folding line of the first front wall piece, the second folding line for the second front wall, which overlaps with the upper wall folding line, which continues in a straight line, The lower wall side where the bending line is not formed is deformed to a larger downward convex shape than the upward convex shape is deformed, and the bag also has a larger downward convexity on the lower surface side with less box resistance than the upper surface side in the microwave oven. It expands into a shape.

  Due to the expansion of the food-sealed storage bag, the fluid in the bag is stored below the pressure release part, and even if the pressure release part is opened due to an increase in the pressure in the bag, it leaks from the pressure release part. Suppressed or prevented to a practical extent.

  When storing, transporting, or displaying food-sealed packaging bags that contain food-sealed packaging bags in a packaging box, the front wall of the packaging box collides with something or is unintentionally opened. In order to prevent the breakage of the second front wall, the box opening start breaking line straddling the line end on the boundary line side with the lower wall of the pair of right and left breaking lines is shortened. The pair of left and right breaking lines of the piece gradually and symmetrically cross each other from the boundary line between the second front wall piece and the lower wall to the free end of the second front wall piece opposite to the boundary line. You may form in the shape of a C so that it may go away.

  Moreover, when the food-sealed storage bag accommodated in the packaging box is inflated with the microwave heating, the upward convex deformation of the box lower wall arranged upward in the microwave oven is suppressed, while the microwave oven The following structure may be adopted so that the upper wall of the box arranged downward can be more reliably deformed in a convex shape downward.

  That is, the front wall includes a front flap following the front ends of the left and right side walls, the front flap is bent inward, and the second front wall piece is bent on the bent front flap. It is the structure which is piled up and the part outside the pair of right and left breaking lines of the second front wall piece is adhered to the front flap.

  In this case, even after the front wall is opened, the outside part of the pair of left and right breaking lines of the second front wall piece is adhered to the front flap, and then subjected to heating in the microwave oven. The rigidity of the box lower wall side arranged upward can be kept larger than the rigidity of the box upper wall side, and the box upper wall arranged downward in the microwave oven can be greatly deformed downward and convex.

  In any case, the pair of left and right breaking lines of the second front wall piece of the front wall is formed, for example, by alternately arranging cutting lines and dotted breaking parts shorter than the cutting lines in a line shape. Can be mentioned. Here, the “cutting line” is a line formed by cutting the wall constituent material so as to penetrate the front and back. The breaking line may be a line in which cutting lines are arranged in a perforated manner.

  The box opening start breaking line may be formed, for example, along a boundary line between the second front wall piece and the lower wall (for example, it may be formed by a cutting line), You may form in the front-end part of the said lower wall adjacent to this boundary line.

In order to solve the third problem, the present invention provides a flat box substrate made of paper (paper-based) that has been cut in advance.

Thus, the food sealed container bag packaging box 1 is formed.

  The packaging box 1 constituting the packaging body 100 described above has a boundary line 141 with the lower wall 14 of the pair of left and right breaking lines C1 and C2 of the second front wall piece 152 constituting the front wall 15. The breaking line c straddling the line end on the side is a breaking line for starting to open the box.

  The packaging box 1 is applied by, for example, applying a finger to the breaking line c for opening the box, and pulling the first front wall piece 151 that is bonded to the second front wall piece 152 in an opening direction. The first front wall piece 151 can be opened.

  At this time, while breaking the pair of left and right breaking lines C1, C2 of the second front wall piece 152, the center portion 152a of the second front wall piece sandwiched between the pair of breaking lines is still The first front wall piece 151 can be opened together with the adhesive. At the same time, the first front wall piece 151 can be opened while being peeled off from the outer side portions 152b of the pair of left and right breaking lines C1, C2 of the second front wall piece 152. As described above, the first front wall piece 151 is deformed or deformed while maintaining the double structure portion together with the second front wall piece portion 152a sandwiched between the pair of breaking lines C1 and C2. Can be opened in a restrained state. FIG. 5A shows such an open state.

  Further, the outer portions 152b of the pair of left and right breaking lines C1, C2 of the second front wall piece 152 can be peeled off from the front flaps 121, 131 and then opened. FIG. 5 (B) shows such an open state.

  FIG. 6 shows an example of the expansion of the bag 2 and the deformation state of the packaging box 1 when viewed from the front wall side of the packaging box when the package 100 with the box 1 opened is heated in a microwave oven.

  In a state where the packaging box 1 is opened at the front wall 15 portion, the folding box 1 is formed so as to overlap with the folding line S3 of the second front wall piece portion 152a opened together with the first front wall piece 151. The folding line S2 of the first front wall piece 151 and the upper wall bending line S1 formed on the upper wall 11 are arranged in a straight line.

  With the box 1 opened as shown in FIG. 5 (A) or FIG. 5 (B), but with the food sealed container bag 2 contained therein, the tray 1 is placed on the tray in the microwave oven with the upper wall 11 facing downward. It can be placed and heated. If it does so, the food F in the food sealed container bag 2 will be heated, and the bag 2 will expand | swell by the vapor pressure which generate | occur | produces by it.

  Due to the expansion of the bag 2, the upper wall 11 (the upper wall 11 arranged downward with a folding line in the microwave oven) and the lower wall 14 (upward in the microwave oven) facing each other. The lower wall 14) receives a tensile force in the vertical direction, so that the upper wall 11 and the lower wall 14 start to deform so as to gradually expand toward the outside of the box.

  At this time, as shown in FIG. 6, the folding line S1 of the upper wall 11, the folding line S2 of the first front wall piece 151, and the second front wall piece 152 that overlaps with the folding line S1 of the upper wall 11 are continued. In the folding line S3, the upper wall 1 side of the packaging box 1 is deformed to a larger downward convex shape than the lower wall side where such a folding line is not formed is deformed upward convex, and the bag 2 is also in the microwave oven. It expands in a larger downward convex shape on the lower surface side with less box resistance than the upper surface side.

  When the microwave oven is heated in the opened state as shown in FIG. 5 (A), the rigidity of the box lower wall 14 side arranged upward in the microwave oven is kept larger than the rigidity of the box upper wall 11 side, The box upper wall 11 disposed downward in the range can be more reliably deformed to a convex shape downward.

  In any case, due to the expansion of the food sealed container bag 2, the fluid in the bag 2 is accumulated below the pressure release part 25, and even if the pressure release part 25 is opened due to an increase in the pressure inside the bag, Leakage from the pressure release portion 25 is suppressed or prevented to an extent that does not interfere with practical use.

  Thus, according to the packaging box 1, the food sealed container 2 can be placed in the microwave oven and the food in the bag can be heated in the microwave oven. It is not necessary to fold a part of the opened box as in the prior art and place it in the microwave oven in a tilted state as a support part, but still the bag contents other than the steam from the pressure release part 25 of the bag 2 Can be suppressed or prevented to a practical extent.

  Further, according to the food sealed container bag packaging 100, the box 1 is adopted as a food sealed container bag packaging box, so the front wall 15 of the box is opened in the same manner as described above, and the upper wall 11 faces downward. When it is placed on the tray in the microwave oven and heating is started, the food F in the sealed food bag 2 is heated, and the bag 2 expands due to the vapor pressure generated thereby, so that the upper wall 11 side of the packaging box 1 is Further, the bag 2 is deformed into a downward convex shape larger than the lower wall 14 side, and the bag 2 also expands in a downward convex shape on the lower surface side with less box resistance than the upper surface side in the microwave oven.

  Due to the expansion of the food sealed bag 2, the fluid in the bag 2 is accumulated below the pressure release portion 25, and even if the pressure release portion 25 is opened due to an increase in the bag internal pressure, the fluid leaks from the pressure release portion. This is suppressed or prevented to a practical extent.

  Thus, according to the package 100, the food sealed container bag 2 can be placed in the microwave oven while the food sealed container bag 2 is stored in the food sealed container bag packaging box 1, and the food F in the bag can be heated in the microwave oven. The packaging box 1 is previously opened at the front wall 15 portion, but it is not necessary to bend a part of the opened box as in the prior art and place it as a support portion in an inclined state in the microwave oven, yet the pressure relief portion of the bag 2 Outflow of bag contents other than steam from 25 can be suppressed or prevented to a practical extent.

  FIG. 7 shows another example 100 'of the food sealed container bag package. FIG. 8 shows an example of the original plate 10 ′ before assembling the food sealed container bag packaging box 1 ′ constituting the package 100 ′. FIG. 9 shows a state in which the packaging box 1 ′ is opened in the packaging body 100 ′. FIG. 10 shows an example of the expansion of the bag 1 and the deformation state of the packaging box 1 ′ when the packaging body 100 ′ with the box 1 ′ opened as shown in FIG. .

  As can be seen from FIGS. 7 to 9, the package 100 ′ is different from the package 100 in terms of the packaging box, but is otherwise the same as the package 100. Further, the packaging box 1 'differs from the packaging box 1 only in the following points. The same reference numerals as those in FIGS. 1 to 6 are assigned to the same parts and components as those of the package 100 and the packaging box 1 shown in FIGS.

The food-sealed storage bag package 100 'is a food-sealed storage bag packaging box 1' containing the food-sealed storage bag 2 '. Instead of the box opening start breaking line c of the box 1, the food sealed container bag packaging box 1 ′ has a box opening start breaking line C 3 at the front end of the lower wall 14 adjacent to the second front wall piece 152. Is formed in an arc shape. In the lower wall portion 14a surrounded by the breaking line C3, a folding line S4 is formed in a straight line following the folding line S3 formed in the portion 152a of the second front wall piece 152.

  In the state in which the front wall 15 portion is opened in the packaging box 1 ′, as shown in FIG. 9, the folding front line S3 of the portion 152a of the second front wall piece and the first front formed so as to overlap therewith. The folding line S2 of the wall piece 151, the upper wall folding line S1 formed on the upper wall 11, and the folding line S4 are arranged in a straight line.

  In FIG. 9A, the breaking line C3 of the lower wall 14 and the pair of left and right breaking lines C1 and C2 of the second front wall piece 152 are broken and sandwiched between the pair of breaking lines C1 and C2. The central portion 152a of the second front wall piece is opened together with the first front wall piece 151 to which it is still bonded, and the first front wall piece 151 is opened together with the first front wall piece 151. A state is shown in which a pair of left and right breaking lines C1, 152 of 152 are opened while being peeled off from both outer portions 152b. FIG. 9B shows a state where the outer portions 152b of the pair of left and right breaking lines C1, C2 of the second front wall piece 152 are also peeled off from the front flaps 121, 131 and then opened.

  With the box 1 opened as shown in FIG. 9 (A) or FIG. 9 (B), but with the food sealed container bag 2 contained therein, the tray 1 is placed on the tray in the microwave oven with the upper wall 11 facing downward. It can be placed and heated. If it does so, the food F in the food sealed container bag 2 will be heated, and the bag 2 will expand | swell by the vapor pressure which generate | occur | produces by it.

  Then, as in the case of the package 100, the upper wall 11 side with the folding lines S1, S2, S3, and S4, which continues in a straight line, is deformed into a downward convex shape larger than the lower wall 14 side. Also, the lower surface side of the microwave oven expands more downward and convexly on the lower surface side with less box resistance than the upper surface side.

  When the microwave oven is heated in the opened state as shown in FIG. 9 (A), the rigidity of the box lower wall 14 side arranged upward in the microwave oven is kept larger than the rigidity of the box upper wall 11 side. The box upper wall 11 disposed downward in the range can be more reliably deformed to a convex shape downward.

  In any case, due to the expansion of the food-sealed container bag 2, the fluid in the bag 2 is accumulated below the pressure release portion 25. Even if the pressure release portion 25 is opened due to an increase in the pressure in the bag, the pressure release portion Leakage from 25 is suppressed or prevented to a practical extent.

  The present invention provides a convenient food-sealed storage bag packaging box for packaging a food-sealed storage bag containing food that can be heated in a microwave oven, and a convenient food-sealed storage for storing the food-sealed storage bag in the food-sealed storage bag packaging box. The present invention can be used to provide a bag package and a box original plate for forming the packaging box.
