Description

  The present invention relates to an outer box for packaging a pouch in which food or the like is enclosed, and more particularly to a packaging box that houses a food-enclosed pouch that is cooked using a microwave and functions as a cooking aid.

  Cooked food filled and encapsulated with fluid food in a packaging bag made of a synthetic resin film may be distributed and sold only in the packaging bag (hereinafter referred to as a pouch). In view of design and display design and hygiene, they are housed in flat outer packaging boxes for distribution and sale.

  Conventionally, in the above-described reheating cooking of foods containing pouches, a hot water roasting method in which a pouch is immersed in hot water heated and boiled with a cooking appliance such as a pan has been used. In addition, in reheating cooking using a microwave oven, reheating cooking is performed by transferring to another container in advance so that the contents do not expand due to heating and the pouch is ruptured. Recently, a number of pouches that can be reheated and cooked with a microwave oven while the contents are sealed have been used by improving the material and structure of the pouch. Among them, a pouch provided with a vent hole structure through which the vapor pressure inside the pouch that rises due to heating passes through an automatic opening has also been proposed, but when placed flat in a microwave oven, the liquid contents However, when the inside of the range is soiled by leaking out from the vent hole structure or the pouch is an upright pouch, the handling operability is good, but there is a drawback that the pouch is easily overturned.

For this reason, various structures have been proposed in which an outer packaging box is used or processed to assist the pouch and to be self-supporting to allow cooking in a microwave oven. Among these, in the flat box-type decorative box used for the outer packaging of the microwave heating pouch, the peeled piece cut line on the upper surface of the box, the side cut line connected to the peeled piece cut line on both sides of the box, A cosmetic box for microwave heating pouches each formed with a fold line connected to the side cut line and a pouch support part cut line connected to the fold line on the bottom surface, which is peeled using a peeling piece cut line, When one side of the peeling part of the cosmetic box is rotated, the bottom surface is bent from the fold line provided on the bottom surface of the cosmetic box, and the pouch support part is cut along the cut line, and the rotated part of the cosmetic box "It is very easy to hold the microwave heating pouch housed inside the vanity box in a stable state,""Dressing for microwave heating pouch" it has been proposed with a completely prevent possible "effect leakage of the contents during (e.g., see Patent Document 1).
JP 2003-170930 A

  In the cosmetic case for a microwave heating pouch described in the above-mentioned document, if the position of the folding line formed on the bottom surface of the cosmetic box is lowered, the tilt angle increases by increasing the size of one side portion of the cosmetic box that is rotated. Since the automatic opening mechanism of the pouch held in the decorative box can be held at a high position, it is easy to prevent leakage of contents from the automatic opening mechanism, but on the other hand, it is difficult to perform the turning operation for opening the box. In other words, because the stored pouch becomes a catching resistance and cannot rotate, the formation position of the fold line cannot be lowered substantially, and it is difficult to increase the inclination angle, and the pouch support part is Because it is a flat plate formed by cutting out a part of the bottom, that is, approximately the center in the width direction, inside the box of the pouch support part due to the bending of the box, wetting of the box and the weight of the pouch or the expansion deformation of the pouch during heating Death Easily occurs, or can not be maintained is inclined state by immersion of the support portion, also since the both widthwise ends of the pouch hardly support portion formed, there is a drawback of easily pouch holding becomes unstable.

  Accordingly, an object of the present invention is to solve the above-described problem, and a microwave oven pouch having an air vent structure portion at an upper portion through which an internal vapor pressure rising by heating passes through an automatic opening is accommodated. A flat outer packaging box that can be opened in an open-up manner without being caught by the stored pouch, and the position of the vent hole of the pouch during cooking is used for leakage of contents, etc. Provided is a pouch packaging box for a microwave oven that can be formed as a cooking aid that can be held at a height that does not occur and that can stably maintain the tilted state of the pouch.

  In order to solve the above-mentioned problem, the invention of claim 1 is a packaging box for storing a microwave oven pouch having an air hole structure portion at an upper portion through which an internal vapor pressure rising by heating passes through an automatic opening, A rectangular side plate, a front plate, a side plate, and a back plate, which form a flat rectangular tubular body, are arranged in order through a fold line, and a ceiling that closes the upper and lower ends of the rectangular tubular body.

Further, the folding cutting lines 13, 13, 13, 13 formed of upward arcuate cutting lines weaken the repulsive force of the back plate folding line L 13.

  Further, in the mounting state described in the preceding paragraph, the microwave oven pouch packaging box P ′ mounted on the mounting surface in the range grounds the top plate 6b of the lid 51 and simultaneously the back plate 4 of the lid 51. The structure is such that the braking protrusion 14 protruding from the ground is grounded and slipping is less likely to occur with respect to the mounting surface in the range as compared to a corner structure formed by folding a normal folding line that forms the corner of the packaging box. Thus, the lid body 51 is maintained in an inverted state, the restoration operation of the lid body is suppressed, and the inclined support state of the pouch is maintained.

  The microwave oven pouch Q accommodated in the microwave oven pouch packaging box of the present invention is usually made of a multilayer plastic film having an excellent gas barrier property and a thermal adhesive layer on the inner surface, and the peripheral portion is thermally bonded into a bag shape. In the so-called four-sided seal bag formed, as shown in the upper part in FIG. 3, the upper part of the pouch Q is located in the vicinity of the peripheral heat-bonded part and adjacent to the heat-bonded part, and part of the stress concentration due to internal pressure. And has a heat-bonding part that surrounds the ventilation hole R. When the internal pressure of the pouch Q rises due to the steam from the processed processed food etc. during heating, the heat-bonding part of the stress concentration part due to the internal pressure peels off. In addition, the internal pressure due to the steam is discharged from the vent hole R to prevent the pouch Q from rupturing and the like, and also prevent the contents from scattering due to the rupture and the like and the contamination in the microwave oven. For this reason, also when accommodated in the microwave oven pouch packaging box P of the present invention, it is necessary to accommodate the vent hole R provided in the upper part of the pouch Q so as to be exposed when the packaging box is opened. In addition, regarding the discharge mechanism of the internal pressure by the vapor | steam in a pouch, it is not limited to the said embodiment.
