不都合が生じた。2. Description of the Related Art It has been popular to store food in an electron beam permeable plastic container and heat it in a microwave oven for cooking. In recent years, foods such as noodles and meat sauce having different cooking temperatures are often distributed in a single packaging container. When heating such a packaging container in the microwave,
Since the contents are heated uniformly, for example, when the noodles are heated to an appropriate temperature, the packaging bag containing the meat sauce is overheated and breaks, and when the packaging bag containing the meat sauce is heated to an appropriate temperature, the noodles are heated. Has the disadvantage of not being sufficiently heated.

れている（例えば特公昭５３−３６４００号参照）。In order to remedy such drawbacks, food is separately placed in each compartment of a dish having at least two compartments in a container in a packaging bag permeable to high-frequency energy to control the amount of high-frequency energy. There is known a method of heating each food item to its optimum temperature using a shielding device (see, for example, Japanese Patent Publication No. 53-36400).

Have control. Therefore, in this method, not only is the operation easy because a shielding device is provided, but in this method, since the food to be heated to a high temperature is uniformly put in the shielding device, it takes a long time to heat, Further, the transmitted high-frequency energy is reflected inside the dish and acts even on the back surface of the high-frequency energy shielding part, so that heating control effects such as heating foods that should not be heated are small, and local complete shielding is possible. It was difficult. Further, it requires a troublesome labor such as the need for a lid member having a through hole portion that partially transmits high frequency energy.

No. -84767). Specifically, this method divides a container for storing food into a plurality of small chambers, and puts the food covered with a packaging material having a different transmittance in each of the small chambers. There were drawbacks such as complexity and complexity.

ものである。The gist of the present invention is that an adhesive layer is formed on either surface of an aluminum foil having an electron beam permeable plastic film laminated on at least one surface. It is a member for electron beam shielding. That is, in the present invention, aluminum aluminum foil is used to shield the electron beam, and the aluminum foil is laminated with a plastic film that transmits the electron beam in order to maintain the strength of the aluminum foil. Further, a pressure-sensitive adhesive layer having an adhesive layer or a release paper for sticking to a packaging container filled with a plurality of kinds of foods is formed.

Of course, a plurality of these films may be used in combination if necessary. The aluminum foil for shielding the electron beam is not particularly limited, but a foil having a thickness of about 5 to 30 μm is usually used. In the present invention, in order to partially irradiate the electron beam, holes or cutouts may be formed in the aluminum foil to adjust the irradiation amount of the electron beam.

The system resin layer may be formed by an ordinary method, or the pressure-sensitive adhesive layer such as an acrylic or urethane type may be formed by an appropriate method. When the pressure-sensitive adhesive layer is formed, paper coated with silicone to protect the pressure-sensitive adhesive layer,
Alternatively, a release paper such as a film is used. When the electron beam shielding member of the present invention thus configured is attached to a container package filled with a plurality of kinds of foods, the adhesive layer of the member is brought into contact with a necessary portion of the container package and heated by an iron or the like. It may be performed by pressure bonding using a tool, or by peeling the release paper to expose the pressure-sensitive adhesive layer and contacting the necessary portion and pressure bonding. The electron beam shielding member of the present invention is cut into a predetermined size, and a plurality of sheets are packaged as one unit for distribution, or if sold as a roll shape cut into a predetermined width, the electron beam can be used at home. It is convenient to use by sticking it to the necessary part of the packaging bag to shield it.

Example 1 An acrylic heat-sensitive adhesive was applied to the other surface of an aluminum foil having a thickness of 7 μm having a thickness of 12 μm of a biaxially stretched polyester film laminated on one side at 30 g / m 2 , and the surface of the adhesive was treated with silicone. An electron beam shielding member having the release paper attached was prepared. The release paper of this member was peeled off, and it was attached from the outside of the self-supporting bag to the source portion of the self-supporting bag in which the soy sauce in the small bag and the sauce in a small bag were filled together and cooked in a microwave oven. As a result, the sauce to which the member was attached was not heated, but the yakisoba portion was cooked at the time of eating.
