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 water inside the pouch boils, the pouch may explode and the hot contents may scatter.
In order to prevent this from happening, the pouch is provided with a steam venting function.
Furthermore, the heating is finished, and the pouch becomes hot when it is taken out.

If a pouch is placed in a paper box so that it can be heated as it is in such a way as to prevent this from happening, it is safer and has the merit that it can be clearly marked even when placed in the microwave.
In particular, there is also a merit that it is safe when taking out due to the heat insulation of the paper box.

  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 strip-shaped opening zipper is provided on the top surface of a microwave packaging box, and the box is opened from the zipper. A pillow is formed by bending the upper side of the back side to prevent the contents from coming into contact with the vapor 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 boxed packaging bag for microwave ovens 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 on the side is used, the contents may come into contact with the steam vent at the time of heating, and the pouch has a special structure as shown in Patent Document 2. There was a problem limited to pouches with different structures.

It is an example of the pouch storage box for ranges of this invention, and is a sectional view in the heating state in a microwave oven, and a perspective view in the state where microwave oven heating is completed and a pouch is taken out. It is an example of the range pouch put into the range pouch storage box of this invention. It is an example of the conventional range pouch storage box, and is a development view of the storage box. In the example of the conventional range pouch storage box, it is a sectional view in the unheated storage state and the state where the upper part of the box is opened and folded.

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 belt-shaped pillow plate portion 3 is connected to one front side plate 131 of the side plate 13 of the paper box and extends to the bottom plate 12 side through the ruled line 30.
Further, the insertion portion 33 is connected to the tip of the pillow plate portion 3.
In addition, there is a pillow ruled line 34 at the center of the pillow plate part 3, and the former pillow plate part 31 and the tip pillow plate part 32 are formed with the pillow ruled line 34 as a boundary.
The pillow plate portion 3 and the bottom plate 12 are bonded via an easily peelable bonding portion 122. As an adhesive used for the easily peelable adhesive portion 122, a vinyl acetate / acrylic copolymer type emulsion adhesive, for example, Cybinol (registered trademark) DBA164 manufactured by Seiden Chemical Co., Ltd., a styrene / acrylic copolymer emulsion, for example, Cybinol (registered trademark) K-1051 manufactured by Seiden Chemical Co., Ltd., an ethylene / vinyl acetate copolymer adhesive, a pseudo-adhesive resin in which a low polymerization degree water-soluble resin and a high polymerization degree acrylic resin are mixed, and the like are also used. I can do things. Furthermore, a method may be used in which a normal adhesive that does not re-peel the easily peelable adhesive portion 122 is applied and the periphery thereof is half-punched.

FIG. 1-2 is a perspective view seen from the bottom side in a state where the pillow plate part 3 is erected.
The peelable adhesive part 122 is peeled off from the bottom plate 12, and the pillow part 3 can be set up by inserting the insertion part into the insertion hole.

Furthermore, the length from the front side plate side end portion to the insertion hole is shorter than the length from the front side plate side end portion to the end portion of the pillow plate portion 3.

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 range pouch is formed.

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 the thickness increases and greatly exceeds the height of the storage box 1. Therefore, the range pouch is pushed inside the opening 111 to break the opening weak line 112 and open it.
The size of the opening 111 is at least one third of the area of the top plate, preferably at least one half and preferably at most two thirds. If the area of the opening 111 is too large, the entire storage box may swell, and the opening weak line 112 may be broken by the force of the range pouch and may not be automatically opened. 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 4. Furthermore, the steam vent 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 venting portion can be grasped.

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. A weak line 1341 is also provided at the margin 1340 on the right side surface.
The strip-shaped pillow plate part 3 is connected from the lower end of the front side plate 131 via the ruled line 30, and the insertion part 33 is connected to the other end of the pillow plate part.
The pillow 3 has a ruled line 34 parallel to the ruled line 30 connected to the lower end of the front side plate 131 and is divided into an original pillow 31 and a tip pillow 32.
An insertion receiving hole 121 is provided at a position that does not reach the insertion portion side end portion of the pillow plate portion 3 from the end surface on the front side of the bottom surface plate 12 on the margin 1310 side. The insertion receiving hole 121 is formed by cutting, and the insertion portion 33 is inserted therein. In order to make it difficult to remove, a slit having a width narrower than the thickness of the insertion portion 33 or a simple cut having no width may be used. A locking piece may be provided in the insertion portion so that it locks when inserted into the insertion hole.
The bottom plate is provided with an easily peelable adhesive portion so that the inner surface of the pillow plate portion 3 is easily bonded.

Examples of the adhesive for the solid coating include a vinyl acetate / acrylic copolymer type emulsion adhesive, for example, Cybinol (registered trademark) DBA manufactured by Seiden Chemical Co., Ltd.
155L, Cybinol (registered trademark) DBA164, Life Bond (registered trademark) AV-650Y4, Lifebond (registered trademark) AV-650Y6 manufactured by Nihon Eikoh Co., Ltd. can be used.

FIG. 4 is an example of a 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.
The range pouch 4 is stored in the range pouch storage box 1 such that the steam vent 41 side of the range pouch 4 is on the side where the pillow plate part 3 is located.

The range pouch 4 is a bag-like pouch whose front and back are sealed with a soft film, 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.
FIG. 6 shows an example of a range pouch used in the present invention. The steam vent 41 of the pouch has a seal portion as shown in FIGS. 6-1 and 6-3 projecting inward from the surrounding fusion portion, and it is peeled away from the surrounding by internal pressure. Opening, or there are holes as shown in Fig. 6-2, and the fusion part around it is peeled off first by the internal pressure, and the fusion around the cut edge is lower than the outer seal part 40 as shown in Fig. 6-4. Any material may be used, such as a film having a bonding 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 insertion portion 33 is inserted into the insertion receiving hole 121 and the pillow plate portion 3 is erected. By raising the pillow 3, the upper part of the range pouch 4 is lifted, and the liquid level of the contents 5 is moved downward to a position where it does not contact the steam vent.
As a result, even if the contents boil, the juice of the contents does not directly spout out.

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 5 boil, and water vapor is generated inside the range pouch 4. Since the internal pressure of the range pouch 4 increases, the range pouch 4 swells and pushes the storage box, the opening weak line 112 is broken, and the opening 111 is opened.
Furthermore, when a certain internal pressure rises in the range pouch 4, the steam vent 41 opens and the steam generated from the steam vent 41 escapes. The steam that has escaped from the steam vent 41 of the range pouch 4 escapes from the opening 111.

  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. A range pouch is placed in the storage box so that the steam vent 41 is oriented away from the opening.
