BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice ball packaging member suitable for packaging frozen rice balls.

[0002]

2. Description of the Related Art Various types of rice ball packaging members have been devised conventionally. For example, the outer sheet member and the inner sheet member are overlapped with each other, and the peripheral portions thereof are welded to form a bag-shaped portion, and sheet-like seaweed is inserted into the bag-shaped portion, and a rice ball is placed on the inner sheet member. Packing rice balls by folding the packaging material, inserting rice balls into the inner packaging material, wrapping sheet-like seaweed around the outer circumference of the inner packaging material, and inserting these into the outer packaging material to package the rice balls Etc. These conventional packaging members use films made of synthetic resin such as polypropylene and polyethylene as the material.

[0003]

[Problems to be solved by the invention] When cooked rice is wrapped in rice balls and sold as it is, the rice is usually dried and hardened. It was only a few days, so the sales period was short.
Therefore, recently, the rice balls are often frozen once and then warmed in a microwave oven or the like together with the packaging at the time of selling or eating.

However, when the frozen rice balls are warmed by a microwave oven or the like, since the conventional packaging member uses a synthetic resin film, it has a high heat retention property, and when the packaging member is held in a hand and opened, it is hot. There was a risk of falling and getting burned.

The present invention has been made in view of the above problems, and an object of the present invention is to hold a packaging member in a hand and open it even if it is taken out immediately after being warmed by a microwave oven or the like. An object of the present invention is to provide a rice ball packaging member for a microwave oven which is not hot and does not drop the rice ball or burn the fingers.

[0006]

[Means for Solving the Problems] In order to achieve the above-mentioned object, a rice ball packaging member for a microwave oven according to the present invention comprises a synthetic resin.
Inside the oil film sheet, metal on the synthetic resin film
Laminate the metal vapor-deposited film sheet pieces
Let's make a rice ball on this metal vapor-deposited film sheet piece
On the sheet and attach the rice ball to the metal deposition part of the sheet piece.
It is made by wrapping rice balls that are touched.

[0007]

[Action] obtained by using the metallized film with a deposit of metallic synthetic resin film package member has good heat dissipation,
The temperature drops immediately after heating.

[0008]

Embodiments of the present invention will be described with reference to the drawings.

The packaging member 1 shown in FIGS. 1 and 2 comprises an outer sheet member 2 and an inner sheet member 3.

The outer sheet member 2 is an outer sheet upper member 4
And an outer seat lower member 5, and an outer seat upper member 4
The lower end of the outer sheet and the upper end of the outer seat lower member 5 are overlapped,
A portion near the lower end of the outer sheet upper member 4 is a non-joint portion 4a,
The inner overlapping portion is welded to the upper end portion of the outer sheet lower member 5 to form a joint portion 4b.

The inner sheet member 3 comprises an inner sheet upper member 6, an inner sheet intermediate member 7, and an inner sheet lower member 8, and the lower end portion of the inner sheet upper member 6 and the inner sheet intermediate member 7 are arranged.
The upper end portion of the inner sheet lower member 8 and the lower end portion of the inner sheet middle member 7 are overlapped with each other.

A sheet-shaped laver a is placed on the outer sheet member 2, and the inner sheet member 3 is superposed on the sheet. Then, the peripheral portions of the outer sheet member 2 and the inner sheet member 3 are welded to form a joint portion 9, and the inner portion is formed into a bag-shaped portion 10 into which a sheet-shaped laver a is inserted.

Here, as the outer sheet upper member 4, the outer sheet lower member 5, the inner sheet upper member 6 and the inner sheet lower member 8, synthetic resin films such as polypropylene and polyethylene are used as in the conventional case, but they are wrapped in rice balls. Sometimes
As the inner sheet middle member 7 which is a portion where the bottom portion of the cut edge comes into direct contact, a metal film vapor deposition film in which a metal such as tin, aluminum or silver is vapor deposited on a synthetic resin film such as polypropylene or polyethylene is used.

The packaging member 1 is used as follows.

As shown in FIG. 3, a triangular rice ball b is placed on the inner sheet member 3 of the packaging member 1 containing the sheet-shaped seaweed a, and the packaging member 1 is placed as shown in FIG. 4 (a). 4 is folded back at the center in the length direction, the corners of the packaging member 1 are bent according to the shape of the rice ball b as shown in FIG. 4 (b), and the corners are connected with cellophane tape or the like to complete the packaging. To do.

To open the package, first, as shown in FIG. 5 (a), the non-joint portion 4a of the outer sheet upper member 4 is pulled in the direction of the arrow to lower the outer sheet upper member 4 and the outer sheet lower member. Separate from the upper end of 5. Then, FIG. 5 (b)
As shown in Fig. 5C, when the left end portion or the right end portion of the inner sheet middle member 7 is pulled out in the arrow direction, the inner sheet upper member 6 and the inner sheet lower member 8 can be removed together with the inner sheet middle member 7, as shown in Fig. 5C. Further, the rice ball b with seaweed a can be taken out from the separating portion between the outer sheet upper member 4 and the outer sheet lower member 5.

When the rice ball packed in a microwave oven is warmed, the inner sheet member 3 that comes into direct contact with the rice ball has a higher temperature, and the inner sheet member 7 has the highest temperature among them. However, since the metal vapor deposition film is used as the inner sheet inner member 7, and the metal vapor deposition film has good heat dissipation, even if it is taken out immediately after being heated by a microwave oven or the like, the left end portion of the inner sheet inner member 7 or When pulling the right end in the direction of the arrow, the onigiri does not drop hot and does not burn the fingers.

[0018] Inner sheath using a piece of metallized film sheet
The middle member 7 is used to hold the heated rice ball.
It can be an appropriate size.

In addition, the metal vapor deposition of the metal vapor deposition film sheet piece
Since the attachment part is covered with the outer sheet member 2,
The electrical insulation from the outside of the mounting member is maintained, and
Reliably prevent short circuit and discharge when reheating
It

It should be noted that the present invention is a rice ball wrapping part having the above-mentioned configuration.
The present invention is not limited to wood, but is intended for the purpose of the present invention.
Suitable for various types of rice ball packaging materials as long as they do not go against
Needless to say, it is used.

Further , the metal vapor deposition film has good heat dissipation.
On the other hand, the heat absorption is also good, so
Heating rice balls in a shorter time than with rice wrapping materials
It also has the effect of being able to.

[0022]

[Effect of the device] The material of the rice ball wrapping material of the present invention is
Vapor-deposited film on which a metal with good heat dissipation is vapor-deposited
, The metal deposition part directly contacts a part of the rice ball.
Since it was configured like this, add rice balls with a microwave oven etc.
Even if you take it out immediately after heating, it will be hot and the onigiri will fall
It does not burn and does not burn your fingers.

Directly on the rice ball which has the highest temperature during heating
Only use metal-deposited film on the contacting inner parts.
Therefore, it does not cost much, and various items at the time of sale
Achieve the required heat dissipation effect while satisfying the requirements
it can.

Further, the metal vapor deposition film has high heat dissipation.
On the other hand, it has a high heat absorption, so the conventional rice ball wrapping
The rice balls can be warmed in a shorter time than the wood.
