なる。According to the present invention, there is provided an outer lid having an opening knob protruding outward and an inner lid, and a cutout for a hot water hole is formed in the inner lid at a position opposed to the opening knob. The outer lid is a lid material having an outer lid cut in the vicinity of the cutout for the hot water drain hole on the side of the opening knob to divide the outer lid into two parts. At least one outwardly protruding hot-water knob is formed at a portion opposite to the hot-hole portion, and the inner lid is disposed between the hot-water knob and the hot-hole cut. A cutout for starting peeling to be divided into two is formed, and at least in a region surrounded by the cut for start of peeling and the cutout for the outer lid, the outer lid and the inner lid are provided with a hot water hole laminated via a release layer. Since it is a lid, when using a package attached with this lid,
After the lid material is partially peeled off from the opening knob side, hot water is poured into the inside of the container and left for a certain period of time, and then the outer lid and the inner lid are partially peeled off from the hot water draining knob side. Since the hot water hole is formed in the hot water hole, the hot water can be easily drained. In addition, since the lid member is thermally bonded to the container opening and sealed, the odor of the contents does not leak out of the package. In the lid material with a hot water hole, the release layer is composed of a combination of a solid release layer and a halftone release layer, and is provided at a position opposite to the peeling start cut formed on the inner lid. By having a configuration in which the solid release layer is formed in a linear shape with a width, the outer lid and the inner lid will be peeled from the solid release layer formed at a position opposed to the separation start cut, Peeling can be easily started. Further, the entire outer periphery of a region surrounded by the peeling start cut and the outer lid cut excluding a solid release layer formed in a linear shape having a predetermined width is a halftone dot formed in a linear shape having a predetermined width. In addition to the release layer, the inside area of the halftone dot release layer is formed of a solid release layer, so that the start of peeling is easily maintained, and the solid release formed in a linear shape having a predetermined width. Since the halftone release layer is provided on the entire outer periphery of the area surrounded by the peeling start cut and the outer lid cut excluding the mold layer, the contents with the lid material attached to the container were wrapped. Since the outer lid does not peel off during transportation and storage in a state, and the inner region is formed of a solid release layer, the outer lid can be peeled off lightly. In the above-mentioned lid material with a hot water hole, the region facing the central portion of the hot water hole cut is formed as a release layer non-forming portion, so that when the outer lid is partially peeled off, Since the portion surrounded by the cut hole can be removed while being adhered to the outer lid, the cut hole can be reliably formed. In the lid material with a drain hole, the cut hole for the drain hole and the cut for starting peeling are half-cut from a surface of the inner lid that is not in contact with the outer lid after the inner lid and the outer lid are laminated. Thus, the hot water drain hole can be reliably formed. In the above-mentioned lid material with a hot water hole, the outer lid is formed of a single paper layer or a laminate of a paper layer and a plastic film, and the inner lid is formed of a polyethylene layer, an aluminum foil, a thermoadhesive resin layer or a polyethylene layer and a paper layer. By using a structure including the aluminum foil and the heat-adhesive resin layer, gas barrier properties are excellent, curling is reduced, and workability when the lid is thermally bonded to the container is improved.
