DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic apparatus in which a heat-generating laminate formed in the shape of a tray is mounted on the bottom of a paper container made in an arbitrary shape, and a cone coated with edible oil and fat is placed thereon and popped in a microwave oven. The present invention relates to a microwave oven package.

[0002]

2. Description of the Related Art Conventionally, there has been known a microwave oven package in which a laminate including a heat generating layer is mounted on a container which has been subjected to a treatment such as oil resistance and heat resistance so that the microwave oven can be cooked. . Above all, many microwave oven packages for popcorn that can be easily cooked in a microwave oven while having fun for both adults and children have been proposed and put into practical use.

For example, FIG. 5 shows a metal vapor deposition layer 22 which generates heat by receiving microwaves on a heat resistant film 23 on the back surface of a bottom plate 31 of a cylindrical cup container made of heat and oil resistant paper and a plastic sheet. The heat-generating laminate 20 with the base paper 21 attached thereto is adhered from above, with the heat-resistant film 23 inside, and a processing cone P dusted with edible oil and fat is accommodated in a cup container, and is shown in FIG. A microwave oven package 30 that covers a lid provided with a small hole through which steam during cooking is released, and hops the treated cone over a microwave oven for a predetermined time. Further, FIG. 6 shows a heat-generating laminate 20 having a heat-generating layer similar to the above-described heat-generating laminate 20 on the inner surface of the bottom plate 31 of a cylindrical cup container (cup container having the same configuration as above) with the base paper 21 inside. Microwave package 30 for popcorn, which is stuck by heat sealing or the like.
It is.

However, the microwave oven package 30 shown in FIG. 5 is provided between the heating laminate 20 and the processing cone P.
Since the bottom plate 31 of the cup container 30 is interposed, it is difficult for the heat of the heat generating laminate 20 to be transmitted. Therefore, unhopped grains of the treated corn P may increase. Then, processing cone P
When microwaved for a long time in order to eliminate unhopped grains of corn, problems such as burning of the corn occur. Also,
When the package 30 for a microwave oven shown in FIG. 6 is heated, the edible oil or fat covered with a cone is melted between the adhesive surface of the heat generating laminate 20 and the bottom plate 31 of the cup container or between the base paper 21 and the heat generating layer. Then, both ends of the heat generating laminate 20 curl upward and peel off, or the base paper 21 and the heat generating layer peel off (not shown). Therefore, if the heat generating laminate 20 is peeled off, the hop rate of the processing cone P decreases,
In addition, problems such as burning of the peeled portion occurred. In addition, all of these cup containers 30 need to be oil-resistant, which increases costs. Therefore, increasing the capacity of the container will further increase the cost.

[0005]

FIG. 2 is an explanatory diagram of a microwave oven package according to one embodiment of the present invention, and FIG. 3 is an explanatory diagram of a microwave oven package according to another embodiment.

According to the present invention, as shown in FIGS. 1, 2 and 3, a tray shaped according to the shape of this paper container is provided on the bottom of a paper container 25 made into an arbitrary shape such as a square or a hexagon. Heating laminate 20 having a heating layer formed by pressing or the like
This is a microwave oven package in which a treated cone P coated with edible oil and fat is placed in the tray-shaped heat-generating laminate 20.

As shown in FIG. 1A, the heat generating laminate 20 is formed by depositing a metal or metal oxide such as aluminum or aluminum oxide on at least one surface of a heat-resistant film 13 such as polyethylene terephthalate (PET). A heat-generating layer is formed by providing a metal vapor-deposited layer 12, and preferably, an oil-resistant base paper 10 is attached to the metal vapor-deposited layer 12 side. Further, as shown in FIG. 1 (B) and FIG. 1 (C), the base paper 10 of the heat-generating laminate 20 is set to the outside, and in a tray shape according to the shape of the paper container (square, hexagon, etc.). It is molded by pressing. As shown in FIG. 1 (C), the tray-shaped heat generation laminate 20 may be provided with a flange F, and there is no particular limitation.

FIGS. 2 and 3 are schematic views of a microwave oven package in which the tray-shaped heat-generating laminate is mounted so as to be fitted into the inner bottom of a paper container 25. That is, as shown in FIG. 2, the shape and size of the paper container 25 described later are adjusted by pressing the base paper 10 of the heat generating laminate 20 to the outside and forming the tray in a deep dish tray by pressing or the like.
The processing cone P is placed on the deep plate of the
Is to accommodate. Thus, when the processed corn P is hopped in a microwave oven, even if the edible fats and oils dissolve, they do not flow out of the tray-shaped heat-generating laminate 20.

FIG. 3 shows another embodiment of the package for a microwave oven. In the same manner as above, the heat-generating laminate 20 is placed with the base paper 10 outside and a tray-like shape with a flange F by pressing or the like. In this case, the end face of the flange F is sized to fit into the inner wall of the paper container 25. This flange F is such that even if the melted oil splashes to the outside of the deep dish portion, it is received by the flange and does not flow between the heat generating laminate and the paper container. In addition, this flange is not particularly limited, and the effect does not change even without it.

FIGS. 4A and 4B show an example of a paper container used for a microwave oven package. FIG. 4A is a plan view of a blank, and FIG. 4B is an assembled view thereof. The paper container 25 in the present invention is not particularly limited, but unlike the conventional one, the paper quality is not oil-leakage due to the tray-shaped heat-generating laminate 20, so there is no need for oil and heat resistance, and it is usually used for snacks and the like. It can be paperboard. Further, the top cover and the bottom cover of the paper container 25 may be any of an adhesive system or an assembling system, and the shape may be square, hexagonal or the like other than the cylindrical type, but the contents can be taken out by breaking the top cover, etc. Preferably, an outlet T for popcorn is provided as shown in the figure.

Hops of the corn are eliminated. Therefore, hops can be completed in a short time with good thermal efficiency, and the corn does not burn. In addition, since the melted oil does not flow outside by forming the tray-shaped heat generating laminate 20, the heat generating portion does not peel off and the hop rate does not decrease. In addition, the heat generating laminate 20
However, it does not come off and burn.

Here, the package for a microwave oven of the present invention (FIG. 2)
Or, using a conventional microwave oven package (shown in FIG. 5 and FIG. 6) and a conventional microwave oven package (shown in FIG. 5 and FIG. 6), a comparative test of popcorn production using a microwave oven was conducted. [Test conditions]-The ingredients used were corn (150 grains) hardened with edible fat.・ Microwave heating output, 500w. Heating time: 2 minutes, 2 minutes 30 seconds, 10 minutes.・ Evaluation method, unhopped grains were counted. Table 1 shows the test results.

[0017]

[Table 1]

The results show that the microwave oven package of the present invention
All corn hopped with a 2 minute heating time. In addition, in the conventional microwave oven package, the heat-generating laminate was peeled off by heating in the microwave oven for 2 minutes and 2 minutes 30 seconds, so that there were many unhopped grains and the peeled portion. Burned. In addition, when the heating time was 10 minutes, all of the wrappings hopped, but all the hop cones were burnt.

[0019]

As described above, the present invention has the following effects. That is, there was only the heat-resistant film between the heat-generating laminate and the treated cone, and the heat of the heat-generating portion was directly transmitted to the cone from the bottom and the surrounding side walls, so that the unhopped grains of the cone were eliminated. Therefore, hops can be completed in a short time with good thermal efficiency, and the corn does not burn. In addition, by making it a tray-like heating laminate,
Since the melted oil does not flow outside, the heat generating portion does not peel off, so that the hop rate does not decrease, and the heat generating laminate does not peel off and burn. Furthermore, the paper container used in the present invention is different from the conventional one, because there is no oil leakage due to the tray-shaped heat-generating laminate, so that the paper quality does not need to be oil-resistant and heat-resistant, and can be a paperboard usually used for snacks and the like. Since no cost is required, an excellent effect is obtained such that the capacity of the paper container can be increased.
