し、注ぎ口を設ける。以下、実施例を記述する。The present invention relates to a lid material for an instant food container. The lid of the instant food container is not only a lid that is directly sealed to the container, but also a plastic outer lid for maintaining strength during transportation and stacked display and for cooking with pouring hot water, etc.
That is, food containers with a cover such as polypropylene or PET are in circulation. In this case, the above object can be achieved, but the cost of the plastic outer lid increases. or,
There are also problems such as inconsistency with recent natural environmental measures and waste measures. In view of these points, the present inventor has developed a lid material that can maintain the strength of a food container without a plastic outer lid (cover lid) and can cope with cooking without pouring hot water or the like without any problem. Invented. This lid material is a multilayer sheet composed of a top sheet and a bottom sheet, and when peeled between the sheets, has little resistance and can be peeled off (peeling force: 5 g /
mm) (pseudo-adhesion). A part of the bottom sheet is cut out (half cut) and a spout is provided. When cooking with pouring hot water or the like, once the top sheet is peeled off, a spout appears. After pouring hot water or the like, the top sheet may be overlapped with the bottom sheet again. The material of the bottom sheet is ASTM D-638
Since the yield elongation according to the test method has elasticity of 18% or more, the lid is kept tight and the food container is strongly held to prevent softening. A release agent layer is provided on the lowermost surface of the base material of the top sheet (the surface in contact with the bottom sheet). An appropriate release agent can be selected from a silicon-cellulose type and a long-chain alkyl type. The substrate may be a single layer or multiple layers. Printing is performed as needed. The bottom sheet is composed of a polyethylene layer, a base material, and a sealant layer. As the substrate, a substrate considering yield elongation, for example, an olefin-based polymer alloy film is used. After pseudo bonding between the release layer of the top sheet and the polyethylene layer of the bottom sheet,
A part of the bottom sheet is cut out (half cut) and a spout is provided. Hereinafter, examples will be described.

0) 1 part was dissolved in 100 parts of toluene to prepare a coating solution,
This was applied and dried so as to have a solid content of 0.1 g / m 2, and a release agent layer was provided to obtain a top sheet. On the other hand, an olefin-based polymer alloy film (Montell-JPO)
A: Flexflex KS-353 40μ) Polyethylene resin (manufactured by Mitsubishi Chemical: LK50) on one side of the surface is laminated with a release agent layer on the top sheet while forming a laminate layer with a lamination thickness of 15μ by a normal hot melt extrusion lamination method. Adhesion was obtained. Then, an ethylene-vinyl acetate copolymer resin (Mirason M-252, manufactured by Mitsui Petrochemical) is laminated on the opposite surface of the olefin-based polymer alloy film to a lamination film thickness of 30 μm by a normal hot-melt extrusion lamination method to form a sealant. Layers were provided. When the bonded product of the top sheet and the bottom sheet is cut into a size suitable for the container, a spout is provided at an appropriate position of the bottom sheet by half cutting.

柔弱化を防いでいる。According to the present invention, a plastic outer lid (cover lid) is formed by a multilayer sheet lid material composed of a top sheet and a bottom sheet.
A lid material that can maintain the strength of a food container even without the above and can cope with cooking without pouring hot water or the like without any problem. The sheets are in close contact with each other so that they can be peeled off with little resistance when peeled off (pseudo adhesion). A part of the bottom sheet is cut out (half cut) and a spout is provided. When cooking with pouring hot water,
If the top sheet is peeled off, a spout will appear. After pouring hot water or the like, the top sheet may be overlapped with the bottom sheet again. The material of the bottom sheet is ASTM D-63
Since the yield elongation according to the 8 test method has an elasticity of 18% or more, the lid is kept tight and the food container is strongly held to prevent softening.
