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 just 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 and the water in the pouch boils as it is, the pouch may explode and the hot contents may scatter and cause burns.
In order to prevent this from happening, the pouch is provided with a steam venting function. However, if the steam venting function part is on the side of the pouch and the liquid, which is a high-temperature content, is in contact with the steam venting function part, the hot content may scatter from the pouch.
Furthermore, when the heating is finished and the pouch is taken out when it is taken out, there is a risk of burns.

To prevent this from happening, it is safer to place the pouch in a paper box and heat it in the microwave as it is. There are also benefits.
In particular, due to the heat insulation of the paper box, there is also an advantage that it is difficult to get burned when taken out.

For heating performed while being put in a paper box of retort food by such a microwave oven, for example, in Patent Document 1, a band-shaped opening zipper is provided on the top surface of the microwave packaging box, and the zipper is opened from the zipper, It is made into a pillow by folding it to the back side on the upper side of the box, so that the contents do not come into contact with the steam vent during heating.
However, it is troublesome for a consumer to perform such a complicated work.

  Patent Document 2 proposes a microwaveable boxed packaging bag with an automatic opening function in which an opening portion provided on the top surface is automatically opened when heated in a microwave oven.

This microwaveable packaging bag for a microwave oven can be cooked without trouble because it can be heated by simply checking the orientation of the box and putting it in the microwave oven.
However, since the steam venting part protrudes toward the opening part, the steam venting part naturally lifts when heated, so there is no risk of the contents coming into contact with the steam venting part. However, when a pouch having a structure in which the steam vent is located on the side is used, the contents may come into contact with the steam vent during heating.

  Therefore, it is an object of the present invention to provide a paper box that accommodates a range pouch that can be cooked by a microwave oven without raising time for cooking and lifting the steam venting portion to a high position and hardly burning. It is a problem.

The present invention is a paper box containing therein a range pouch that can be cooked by a microwave oven, and includes a plurality of breakable weak lines provided across a side plate and a bottom plate of the paper box, and a weak line and a weak line. There are a plurality of foldable ruled lines provided between them, and a movable part surrounded by the center part of the ruled line provided on the bottom plate is a convex cut, and the movable part is formed by the convex cut. A range pouch storage box is characterized in that a pillow portion is formed that protrudes outwardly from the inner side of the paper box when it is moved.

The range pouch storage box of the present invention can form a pillow portion that tilts and fixes the steam vent of the range pouch upward by simply pushing the movable portion. For this reason, it is possible to perform cooking with a microwave oven so that the contents do not erupt without any effort.
In addition, since the opening is provided at a position away from the pillow portion from which the high-temperature steam is discharged, there is an effect that, when taking out from the box, it is difficult to take a burn.

It is an example of the range pouch storage box of this invention, and is the perspective view seen from the upper surface side in the state which pushed the movable part and stood the pillow part, and the state heated with the microwave oven. It is an example of the range pouch storage box of the present invention, and is a development view of the storage box. It is an example of the range pouch storage box of this invention, and is sectional drawing in the unheated storage state and the state which pushed the movable part and raised the pillow part. It is an example of the pouch storage box for ranges of this invention, and is sectional drawing in the heating state in a microwave oven, and the state which microwave heating finishes and takes out a pouch. It is an example of the range pouch put into the range pouch storage box of this invention.

Hereinafter, an embodiment of a range pouch storage box of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an example of a range pouch storage box according to the present invention, and FIG. 1-1 is a perspective view seen from the bottom side in an unheated storage state.
The range pouch storage box 1 has a flat rectangular parallelepiped shape, and is provided with side plates 13 standing vertically on four sides of the bottom plate 12.
A right fragile line 31 and a left fragile line 32 are provided in communication with one front side surface plate 131 and the bottom surface plate 12 of the side surface plate 13, and an upper ruled line 33 and a bottom surface plate 12 side end are provided at the upper ends of these weak lines. The part is provided with a pillow ruled line 34. A portion surrounded by the right fragile line 31, the left fragile line 32, the upper ruled line 33, and the pillow ruled line 34 becomes the movable portion 3 by cutting the fragile line.
In addition, a pillow portion 35 is provided by cutting at the center of the pillow ruled line 34 on the bottom plate 12 side so as to protrude outwardly when the movable portion 3 is moved.
Furthermore, at least one ruled line is provided between the front side surface plate 131 and the bottom surface plate 12 of the movable part 3, which serves as a pushing part for pushing the movable part 3 into the storage box. As indicated by 1-1, when the pushing portion 36 formed by the pushing ruled line 361 formed by two arcs is inclined, it is easy to push.

FIG. 1-2 is a perspective view of a state in which the movable portion is pushed and the pillow portion 35 is erected, as viewed from the bottom surface side.
The right fragile line 31 and the left fragile line 32 of the movable part 3 are lines that are partially cut like a perforation or cut by half punching that cuts some of the thickness. It is easily cut by pushing.
In particular, the lengths of the right fragile line 31 and the left fragile line 32 in the bottom plate are formed slightly longer than the height of the side plate 13. Therefore, when the pushing portion 36 is pushed in, the side plate portion of the movable portion 3 is pressed against the top plate 11 and is fixed in a state where the movable portion 3 is pushed. At this time, the pillow portion 35 jumps out of the bottom plate 12 and stands up at the same time.

FIG. 2 is an example of the range pouch storage box of the present invention, and FIG. 2-1 is a perspective view seen from the upper surface before heating in the microwave oven in a state where the movable portion 3 is pushed and the pillow portion 35 is raised. It is.
An opening weakened line 112 is formed in the upper surface plate 11, and an opening 111 having a large area that can be opened to take out the pouch is formed.
It is preferable that the opening 111 is separated from the position 113 facing the movable part on the upper surface plate 11 so as not to interfere with the movable part 3 when the box is assembled.

FIG. 2-2 is a perspective view seen from the upper surface side in a state heated by a microwave oven.
In the range pouch, the water contained in the contents is boiled by high-frequency heating, and the volume is increased to swell. When inflated, the range pouch tends to be nearly spherical and increases in thickness, greatly exceeding the height of the storage box 1. Therefore, the pouch presses the inside of the opening 111 to break the opening fragile line 112 and open it.
The size of the opening 111 is not less than one-third, preferably not less than one-half of the top plate area, and preferably not more than two-thirds. If the area of the opening 111 is too large, the entire storage box swells and the opening weak line 112 is broken only by the force of the range pouch. Therefore, the opening cannot be opened unless it is cut with scissors or hands. Moreover, when it is smaller than 1/3, there is a problem that it is difficult to take out the range pouch from the storage box.
In addition to the area, it is preferable to widen the maximum width of the opening 111 to the vicinity of the width excluding the seal portion from the width of the range pouch. Further, the steam vent 41 of the range pouch is accommodated so as to be located on the side opposite to the opening 111. As a result, when taking out the range pouch, the side opposite to the steam vent can be grasped, so there is no risk of burns when taking out.

FIG. 3 is a development view of an example of the range pouch storage box 1 according to the present invention.
An opening fragile line 112 runs from the top plate 11 to the right side plate 134, and an opening 111 is formed. In addition, a weak line 1341 is also provided at the margin 1340 on the right side surface.
A right weak line 31 and a left weak line 32 are provided from the bottom plate 12 to the margin 1310 of the front side plate, and a weak line 1311 is also provided on the front side plate 131.
It is preferable that the right fragile line 31 and the left fragile line 32 have a square shape from the front side plate 131 side toward the bottom plate 12. This is to make the pillow ruled line 34 long in order to form a sufficiently large pillow part 25. However, if the movable part is too large, it will be difficult to push the pillow ruled line 34. This is because we want to make it as small as possible.

FIG. 4 is an example of the range pouch storage box according to the present invention, and FIG. 4A is a cross-sectional view of the storage state in an unheated state.
A range pouch 4 is stored in the range pouch storage box 1.
The range pouch 4 is a bag-like pouch with a soft front and back and a sealed periphery, and is made of a strong film that is not easily damaged even at high pressure and high temperature.
The range pouch 4 has a steam vent 41 so that when the internal pressure exceeds a certain level, the steam inside is released.
The steam vent 41 has a seal portion as shown in FIG. 6A and FIG. 6C that protrudes inward from the surrounding fusion portion, and is peeled off before the surrounding due to internal pressure. As shown in FIG. 6-2, there is a hole, and the surrounding fusion part is peeled off first by internal pressure, as shown in FIG. Any material may be used, such as a film having a low fusion strength.

FIG. 4-2 is a cross-sectional view of the range pouch storage box in an unheated state immediately before heating the microwave oven.
The movable part 3 is pushed in and the pillow part 35 is erected. By raising the pillow portion 35, the upper portion of the range pouch 4 is lifted and moved downward to a position where the content portion does not contact the steam vent portion. Thereby, even if the contents boil, the juice of the contents and the like are not directly ejected to the outside.

FIG. 5 is an example of the pouch storage box for the range of the present invention, and FIG. 5-1 is a cross-sectional view in a state where the microwave oven is heated.
The contents are boiling and water vapor is generated. When the internal pressure of the range pouch 4 increases, the range pouch 4 swells, spreads out the storage box, the opening weak line 112 is broken, and the opening 111 is opened. Further, the steam generated from the steam venting part is released from the range pouch 4 when a certain internal pressure rises. The steam escapes mainly from the vicinity of the movable portion 3 because the left and right sides of the nearby movable portion 3 are wide open.

  FIG. 5B is a cross-sectional view illustrating a state in which the microwave oven pouch 4 is taken out by opening the opening 111 after the microwave heating is completed, the boiling is stopped, and the vapor removal is completed. Since there is a risk that the contents leak from the steam vent 41, take it out as much as possible.

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 / polyethylene terephthalate / aluminum foil / polyethylene / polyamide / polyethylene,
Polypropylene / aluminum foil / polyethylene / polyamide / polyethylene,
Polyethylene terephthalate / aluminum foil / polyethylene,
Such a configuration is conceivable.
The aluminum foil plays the role of not letting out the scent, and the thickness is 12 to 24 micrometers. A polyethylene oxide vapor deposited polyethylene film or the like may be substituted. Moreover, the thickness of a polyethylene terephthalate film can use 8-25 micrometers.
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 of the present invention can be easily assembled if it is set in a general cartoning machine. First, the sleeve is raised, the range pouch 4 filled with the contents such as curry is loaded, the side plate is folded, and it can be automatically assembled through the hot melt adhesive at an appropriate time.

The range pouch storage box 1 according to the present invention is as described above. Simply push a finger into the folding part 3 to push it in, raise the pillow part 35, and heat it in a microwave oven with it down. , No tools are required, cooking can be done quickly, and there is no problem of the contents spurting out by heating.
In this way, it takes less time and is in a paper box after heating, so there are significant advantages such as being able to be taken out of the microwave oven without causing burns.
