Description

{Packaging bag for microwave oven}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging pouch for a microwave oven, and more particularly, to a packaging pouch for a microwave oven which can be cooked by mixing contents packed in two storage spaces by heating the microwave oven, To a packaging pouch for a microwave oven.

Generally, when a packaging bag filled with a retort food, a frozen food or the like is heated by a microwave oven, the pressure inside the envelope rises due to water vapor generated from the contents by heating, the packaging bag ruptures and the contents are scattered, This may damage the inside of the microwave oven due to breakage, and may reduce the risk of burns or the like to the human body.

Therefore, before the packaging bag is heated and cooked by a microwave oven, the packaging bag is partially opened in advance, or a hole is made in the packaging bag body to discharge water vapor or the like generated in the packaging bag to the outside, We take measures to prevent destruction.

However, this approach is time-consuming for the average consumer. In addition, when this method is employed, since the steam generated by the microwave heating is immediately discharged out of the packaging bag, there is a drawback that the steamed effect of heating the contents by steam is reduced and the taste is deteriorated.

As a conventional technique for solving such a conventional problem, a packaging bag for a microwave oven of Patent Document 10-2008-0007647 has been proposed.

1 and 2 are schematic views showing a packaging bag for a microwave oven according to the prior art.

The packaging bag 1 of the prior art described above is provided with an outer sealing portion 3 at the corner portion, an unsealed portion 4 adjacent to the outer sealing portion 3, The steam discharge seal portion 6 formed by the weakened portion 5 formed by the through hole of the die is formed by being connected to the edge seal portion 2. [ A notch 7 for opening the packaging bag 1 after completion of the microwave heating is formed in the vicinity of the upper end portion of the edge sealing portion 2.

The weakened portion 5 is formed such that its width is gradually enlarged from the leading end portion of the opening to the rear end portion. The rear end of the weakened portion 5 is divided into two chambers 52 and 53 by forming the protruding portion 51 from the rear end toward the inside of the weakened portion 5.

As shown in FIGS. 1 and 2, the vapor discharge seal portion 6 of the packaging bag 1 has a center point P of a circle in contact with the center of the inner edge of the two side edges of the packaging bag P (P) from the center point P of the packaging bag to the center of the inner edge of the edge seal at the short side is set as a radius on the circle R, And the initial break point B of the steam discharge seal portion 6 is located.

At this time, the initial breaking point B of the steam discharge seal portion 6 means that the opening of the outer seal portion 3 is started in the steam discharge seal portion 6 when the packaging bag is heated by the microwave oven .

However, in the packaging bag of the prior art as described above, the cooking pressure is controlled according to the bonding width and the bonding strength of the outer sealing portion 3, and the bonding width and the strength of the sealing portion 3 must be precisely adjusted If there is a problem, or if not, there is a problem that the steam is not discharged at an appropriate pressure, an accident that the envelope is blown by the steam pressure occurs, or the steam is discharged too early and the cooking is not properly performed.

To solve this problem, Patent Registration No. 10-1194780 is disclosed.

The patent discloses that a steam discharging portion is formed in a sealing weakening portion where an adhesive tape and a sealing frame portion are overlapped with each other and the elastic tape is formed into a plurality of sealing portions having a plurality of strips to facilitate pressure control.

However, since the above-mentioned patent is inconvenient and troublesome to form by the multiple sealing part, the efficiency such as the manufacturing time of the packaging pouch is not high, and the space between the multiple sealing parts and the steam discharging part are communicated with each other, There is a possibility that foreign substances may be introduced into the space and the food may be discharged to the outside through the steam discharging portion after discharging the steam.

In addition, since the above-described patent is a packaging pouch having a single receiving space, there is a disadvantage in that it is impossible to mix different kinds of foods and cook them. Even if the internal space is formed as two receiving spaces, It is possible to peel off the tape from any side of the adhesive tape, and the food and beverage contained in the inside of the tape can not be properly mixed.

Hereinafter, a packaging pouch for a microwave oven according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 to 7, a packaging pouch for a microwave oven according to the present invention includes a sealing joint 10 formed by fusing the edges of a film so as to form a space for accommodating food therein, And an inner space formed by the inner space formed by the inner space formed by the inner space and the inner space formed by the inner space formed by the outer space and the inner space formed by the inner space formed by the outer space And a discharge hole (30).

The eyedropper tape 20 separates the accommodating space in the packaged state, but separates the two accommodating spaces as being peeled off when heated by the microwave oven. Accordingly, the food recipient can mix the foods accommodated in the respective accommodation spaces and then ingest them.

At this time, the peeling guiding portion 21 is formed on the easy paper tape 20 such that the joining area is gradually widened toward the both sides from the center portion.

When the microwave oven is heated by the formation of the peeling guide portion 21, the peeling guide portion 21 is peeled from the central portion of the diaper tape 20 as shown in FIG. 4 and is pushed to both sides. The steam is discharged and the peeling is stopped. As a result, all the compartment portions of the internal accommodation space are peeled off, and the food and beverage contained in the respective accommodation spaces can be smoothly mixed.

At least two or more vapor discharge holes 30 are formed in the vicinities of both ends of the eyecup tape 20 so that the vapor discharge holes 30 are formed at different positions .

The reason why the positions of the steam discharge holes 30 are different from each other is that steam is discharged while automatically regulating the number of openings according to the amount and pressure of the steam due to the heating of the food stored in the accommodation space.

That is, the amount and the pressure of the steam are different depending on the type of foods accommodated in the accommodation space. The amount of the steam and the pressure thereof determine the opening number of the vapor discharge hole, thereby preventing the packaging pouch from being blown by the steam pressure, So that too much steam is prevented from being discharged, and the cooking is smoothly performed.

Specifically, the steam discharge hole 30 is formed in a longitudinal direction of the edible tape 20 at a position nearest to the center of the eyedropper tape 20 and has a rectangular first vapor discharge hole 31 A rectangular shape formed so as to be spaced apart from one side of the first vapor discharge hole 31 and positioned farther from a center of the easy paper tape 20 than a position of the first vapor discharge hole 31; And a second vapor discharge hole (32).
At this time, one side of the second vapor discharge hole (32) is positioned on the same vertical line as the other side of the first vapor discharge hole (31).

3, three steam discharge holes 30 are formed, and each steam discharge hole is formed so as to be sequentially moved away from the central portion of the eyepiece tape, as well as the other side of the first steam discharge hole 31 One side of the second vapor discharge hole 32 in the second order is formed on the same vertical line so as to be partially overlapped with the other side of the second vapor discharge hole 32 in the second order, And one side of the vapor discharge hole 33 is formed so as to be located on the same line so as to partially overlap.

Accordingly, only the first steam discharge hole 31 may be opened or the second steam discharge hole 32 may be opened together with the first steam discharge hole as shown in FIG. 5A, depending on the amount and pressure of the steam generated when the microwave oven is heated. Or as shown in FIG. 5C, it is opened to the third vapor discharge hole 33.

The steam discharge hole 30 of the present invention may be formed to be discharged in one direction or both directions to the overlapping portion of the seal bonding portion 10 and the adhesive tape 20. The amount of the discharged steam is increased as much as it is discharged in both directions compared to the one direction.

At this time, the opening and closing film 40 may be installed on the surface of the film on which the vapor discharge hole 30 is formed to cover the vapor discharge hole 30.

The opening / closing film 40 is heard by the steam discharged when the steam is discharged, and the steam discharging hole 30 is opened. After the discharge of the steam is finished, the opening / closing film 40 is lowered and returned to close the steam discharging hole 30.

Accordingly, the discharge of the steam is shut off to maintain the sealed state of the inside, so that it is more efficiently cooked.

Here, an adhesive 45, which is dissolved by the steam to be discharged, is applied to the inner surface of the opening / closing film 40.

When the open / close film 40 is lowered and returned to its original position after the vapor is discharged in the state that the adhesive 45 is dissolved by the vapor, the open / close film 40 is attached to the surface of the film, .

As the vapor discharge hole is closed by the adhesive 45, the source of the cooked food or soup is prevented from being discharged to the outside through the vapor discharge hole, and the microwave oven or the packaging pouch is dirty by the food .

According to the present invention configured as described above, in the case of heating different kinds of foods contained in the respective accommodating spaces and cooking them, the peeling guide tape smoothly separates the edible tapes so that the foods are effectively mixed and the amount and pressure of the steam The steam discharge is automatically controlled and the external discharge of the steam discharge hole is blocked after the discharge of the steam, thereby preventing the external discharge of the food.
