Description

  The present invention relates to a range pouch storage box that can be cooked by high-frequency heating in a microwave oven while the range pouch is placed in a paper box.

Foods that can be tasted only by heating, such as cooked retort curry, can be eaten easily, so in recent years not only singles but also elderly people and cooking have not been able to spend time It has become a means for people to eat easily.
Such foods include curry, stew, sweet and sour pork, meatballs, and Happo vegetables that contain moisture inside and cause an excitation phenomenon that raises the energy level at high frequencies, causing vibration and rotation. The other ingredients in the surroundings are also cooked by transferring their energy. A portion of the heated water expands as steam and becomes a force that pushes the pouch, which is a packaging container, from the inside, increasing the internal pressure and bulging round.
If the pressure inside the pouch rises as it is and the generated steam does not escape to the outside, the pouch may rupture and the hot contents may scatter. In order to prevent this from happening, the pouch is provided with a steam venting function.
Furthermore, when the heating is finished and the pouch is at a high temperature when it is taken out, there is a risk of burns if it is taken out immediately after the heating.

To prevent such an accident from happening, it is safer to put this pouch in a paper box and heat it directly in a microwave oven. is there.
In particular, the heat insulation of the paper box has the advantage of being hot and easy to hold.

Regarding heating performed while being put in a paper box of retort food by such a microwave oven, for example, in Patent Document 1, a food sealed container bag packaging box for packaging a food sealed container bag that hermetically contains food that can be heated by a microwave oven Yes,
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 has a lower wall bending portion extending between lower ends of the left and right side wall breaking portions, and proposes a food sealed container bag packaging box. This food-sealed container bag packaging box can be cooked without any trouble since it can be heated by simply checking the direction of the box and placing it in a microwave oven.

However, when heating the microwave oven, the front side wall and the part near the front end of the upper wall from the central breaking part, the left side wall near the front end from the left side wall breaking part, the right side wall near the front end from the right side wall breaking part, and the lower wall for bending Even if the pillow part constituted by the lower wall or the like closer to the front end than the part is bent by the lower wall bending part, it repels and tries to return.
In particular, (1) the bottom wall bending part does not bend further even if it is bent 180 degrees, (2) there is a steam vent for the microwave oven near the opening, and the center of gravity is on the rear side (3) The entire packaging box containing the pouch is tilted with the opening on the upper side, which causes the range pouch to move to the rear side, and the pillow portion is stably bent. It cannot be secured.
In addition, since there is a force when the pillow portion and the surrounding connecting portion are broken, excessive force is applied and the lower wall folding portion tends to break.
Furthermore, since it cannot be heated while holding the food sealed container bag packaging box, the pillow part will come off the lower wall of the box during heating in the microwave unless it is bent 180 degrees at the lower wall folding part. As a result, the entire packaging box containing the pouch could not be tilted, and the contents boiled during heating, causing a problem that the liquid leaked vigorously.

  Therefore, when heating the microwave oven, the easy-breakable part can be tilted so that it can be surely broken, the pillow part can be bent firmly, and the opening side can be surely turned upward. Provide a box.

A bottom plate 12, a front plate 131 following the front end of each face plate, and a rear plate 132 following the rear end are provided.
An upper surface opening easy cutting line 111 is provided near the front surface plate of the upper surface plate 11, and is continuously connected to the upper surface opening easy cutting line 111, and the left side opening easy cutting line 1111 is provided on the left side plate 133 and the right side surface opening is provided on the right side plate 134. The easy opening line 1112 and the right side plate margin 1340 are provided with a right side margin opening easy cutting line 11120.
These easy-cutting lines are constituted by broken perforations, and can be cut by pushing in the easy-cutting line or by deforming the storage box. Usually, the broken line perforations are set such that the length of the cut is sufficiently shorter than the length of the cut.
The top opening easy cutting line 111 has a large curvature at the center and a bulging curve toward the center of the box. This is to make it easy to break the top opening easy cutting line 111 from the center. In addition, it is also possible to insert a hand from a part of the broken upper surface opening easy cutting line 111 and widen the broken part to easily expand the opening part to the side easy cutting line. In addition, the pouch can be easily taken out after the range heating.

At the boundary portion between the top plate, the left side plate, the right side plate, and the bottom plate, the easy-to-open cutting line is immediately cut by providing a slight uncut portion of about 0.3 to 0.8 mm. It is like that.
When assembling the storage box and storing the pouch, or when transporting with the pouch stored, make it difficult for breakage to start from the boundary corresponding to the corner of the box that is susceptible to physical impact from the outside. Can do. Further, when opening the storage box, the cut that starts to break along the perforation can be cut only in an assumed range without spreading to other positions at the boundary portion.

FIG. 1-2 shows an enlarged view of the vicinity of the bottom fold line 121 and the bottom cut line 122.
The bottom plate 12 was provided with a bottom fold line 121 connected to the easy-to-open cutting line and a bottom cut line 122 arranged in a broken line shape so as to overlap the fold line.
The bottom fold line 121 is connected to the left side opening easy cutting line 1111 and the right side opening easy cutting line 11120. When the left side opening easy cutting line 1111 and the right side opening easy cutting line 1112 are continuously broken, if the bottom side opening easy cutting line 1112 is broken as it is, the bottom folding line 121 or the like The unintended portion of the face plate 12 tends to break.

Therefore, the bottom cut line provided in the vicinity of the left side plate 133 and the right side plate 134 is a bent cut line that is inclined so that one end on the center side of the plate faces the lower end of the bottom plate. Here, what is provided in the vicinity of the left side plate 133 is a left turn cut line 123, and is provided in the vicinity of the right side plate 134 as a right turn cut line 124. The bent cut line only needs to be provided in the vicinity of the left side plate 133 and the right side plate 134. For example, as shown in FIG. 1, the bottom cut line may be provided at a position closest to the left side plate and the right side plate. Although not shown, the bottom cut line may be provided at the second closest position from the left side plate and the right side plate, but is not limited thereto.
The upper surface opening of the upper surface plate is opened when the upper portion of the upper surface opening easy cutting line 111 is broken with a finger and then the front plate side and the rear surface plate side are respectively grasped and the storage box is folded and opened. It is assumed that the left side opening easy cutting line 1111 and the right side opening easy cutting line 1112 connected to the easy cutting line 111 are well broken with momentum. However, even if a force is applied to the bottom fold line 121 as it is, the left bent cut line 123 and the right bent cut line 124 are bent so that the direction in which the breaking force is directed to the position where the bottom bent line 121 is located. It can be removed so as not to go. As a result, it is possible to protect the bottom folding line 121 between the left bend cut line 123 and the right bend cut line 124 from being cut.
As a result, damage to the pillow part used when tilting the pouch storage box, the bottom plate, and the bottom fold line corresponding to the joint between the pillow part and the bottom plate can be suppressed, and problems during heating of the range will not occur. Become.

The bottom plate is provided with a bottom fold line 121 and a bottom cut line 122 arranged in a broken line so as to overlap the fold line. Ensure that the length of the portion separated by the broken bottom cut line is not more than 60% of the length between the left and right ends, so that it is not cut off. ing.
At this time, the perforated part is securely bent, so it is easy to bend and the bending is difficult to return, and the pillow part 5 can be erected and the pouch storage box can be tilted and placed inside the range. it can.

  Furthermore, as shown in FIG. 1-1, the front and upper plates, the rear and upper plates, the margin and the bottom plate of the front plate, and the margin and the bottom plate of the rear plate are formed by half-cutting in a broken line shape. In addition, a semi-cutting process may be performed, and a sewing blade may be provided around the back surface side center of the bottom plate as a finger hole portion 125 to facilitate disassembly when the storage box is discarded.

FIG. 2-1 is a perspective view illustrating a state of a first step in which assembly is started from a blank created according to a development view.
The right side plate 134 and the margin 1340 of the right side plate are glued together to show a state where the storage box has a square cylindrical shape.

FIG. 2-2 is a perspective view of a state in which the pouch 2 is stored while assembling the storage box.
That is, the right rear flap 1342 and the left rear flap 1332 are folded, and the rear plate margin 1320 and the rear plate 132 are bonded together while being folded.
In this state, the microwave oven pouch that is the contents is stored such that the steam release portion 21 is disposed at a position close to the top opening easy cutting line 111.
Then, the right front flap 1341 and the left front flap 1331 are folded, and the front plate margin 1310 and the front plate 131 are bonded together while being folded.

FIG. 3A is a cross-sectional view of the pouch storage box 1 in a state where the pouch is stored.
The pillow portion 5 includes a front plate 131 and an upper plate 11 closer to the front plate than the opening easy cutting line, a left side plate closer to the front plate than the opening easy cutting line, a right side plate closer to the front plate than the easy opening line, and a bottom folding line. It is composed of a bottom plate 12 near the front plate, etc., and is integrated with the trunk of the storage box in a state where the opening easy cutting line is not broken.
The pouch 2 stored in the pouch storage box 1 contains the contents 3, but is slightly in the state of containing a gas 4 such as air or water vapor.
The periphery of the pouch 2 is sealed with a seal portion 20, and a steam vent portion 21 is provided at one end thereof and is disposed at a position close to the pillow portion 5.

FIG. 3B is a cross-sectional view illustrating a state in which one end along the upper surface opening easy cutting line 111 is pushed and broken.
The upper surface opening easy cutting line 111 is formed by cutting with a perforated blade in a broken line shape, and the broken line perforation is set so that the remaining length is sufficiently shorter than the separated length. It can be broken by pressing.
The top opening easy cutting line 111 has a large curvature at the center and a bulging curve near the center of the box. The opening can be expanded to the easy cutting line.
Further, after the center portion of the upper surface opening easy cutting line 111 of the upper surface plate is broken with a finger, the front plate side and the rear surface plate side are respectively grasped, and the storage box can be folded and opened.

3-3 is a cross-sectional view showing a state where the pillow part 5 is bent 180 degrees along the bottom fold line 121 and the pouch storage box 1 is inclined and placed in the microwave oven.
When tilted, the gas 4 inside the pouch 2 moves to the vapor vent 21 side, and the contents 3 are separated from the vicinity of the vapor vent 21.
In this state, hang it on the microwave.
When placed in a microwave oven, the contents 3 inside the pouch boil and generate a large amount of water vapor. The pouch 2 swells with the generated water vapor. When the inside of the pouch 2 reaches a certain pressure, a small steam vent 21 opens.
Even if the steam vent 21 is opened, the pouch 2 is inclined and the contents 3 are not in direct contact with the steam vent 21, so that only steam is discharged from the steam vent 21, heated in the microwave, and cooked. .
Therefore, the contents do not scatter and can be cooked reliably.
In addition, an upper surface board and a lower surface board also deform | transform large also in the box trunk | drum which the pillow part 5 supports because a pouch expands at the time of this heating. At this time, since the pillow part 5 is not deformed, the stress due to the deformation is concentrated on the bottom fold line corresponding to the joint between the box body part and the pillow part. However, since one end on the center side of the bent cut line is inclined so as to face the bottom plate, the stress is hardly transmitted from the bent cut line to the bottom fold line adjacent to the bent cut line. As a result, the bottom fold line is not easily broken. Therefore, the pouch can be reliably tilted and supported even during heating.

FIG. 4 shows a typical example of the pouch 2 having the steam vent 21 of the pouch 2.
Laminated films are arranged on the front and back sides, and a seal portion 20 is provided around, but the seal portion is deformed to provide a vapor vent portion 21.
For example, in the steam vent 31 shown in FIG. 4A and FIG. 4D, the seal portion protrudes inward from the surrounding fusion portion, and the opening is peeled off before the surrounding due to internal pressure. It opens with the mechanism to do.
Also, as shown in Fig. 4-2 and Fig. 4-3, there are holes, and the surrounding fusion part peels off first by internal pressure, but there is a steam vent near the end of the pouch. As long as it is provided and only the steam venting portion is opened and only the water vapor is discharged, any type may be used.

The range pouch used in the present invention can be a film having the same structure as a normal retort pouch.
For example, from the outer layer, polyamide / maleic anhydride modified polyethylene / polyamide / polyethylene / vinyl acetate copolymer saponified product / maleic anhydride modified polyethylene / polyethylene, polyethylene / silicon oxide deposited polyethylene terephthalate / polyethylene / polyamide / polyethylene,
Polypropylene / silicon oxide-deposited polyethylene terephthalate / polyethylene / polyamide / polyethylene,
Silicon oxide-deposited polyethylene terephthalate / polyethylene,
Such a configuration is conceivable.
The polyethylene film deposited with silicon oxide plays a role of not letting out the scent. The thickness of the polyethylene terephthalate film can be 8-25 μm.
These films can be produced by a normal dry lamination machine, an extruder laminating machine or the like.

The mount used for the range pouch storage box varies depending on the weight of the contents, but the basis weight, which is the thickness of the paper, can usually be used in the range of 120 g / m ² to 400 g / m ² . Further, the density of the paper is set in the range of 0.6 to 1.1 g / cm ³ .
The inner surface or inner and outer surfaces may be coated with polyethylene or the like.

The range pouch storage box 1 according to the present invention is configured as described above, making it easy to cut the broken portion around the pillow portion, and releasing the force applied during opening and heating near the left and right ends of the bottom plate. It is provided so that the connection between the bottom plate and the pillow portion is not cut too much.
In addition, it is a pouch storage box that can be stably heated by a range because it is easy to be folded at the bottom fold line connecting the pillow portion and the bottom plate and the pillow portion can be reliably folded 180 degrees.
Further, since these manufactures can be handled only by changing the shape of the punching blade, the productivity is high and the cost is hardly required, and the merit of the present invention is great.
