している。However, in the lid material in which the peeling start cut is formed in the vicinity of the knob portion of the inner lid, a slight deviation occurs in the position of the peeling start cut from the punched peripheral edge of the lid material in the step of manufacturing the lid material. At the same time, when the lid material is attached to the container, the relative positions of the lid material and the container will be slightly displaced, so when the lid material is thermally bonded to the container, the peeling start cut position is the outer edge of the heat-bonded part. The outer edge of the heat-bonded portion may be displaced to the outside or the inside without being located at. If the position of the peeling start cut is outside the outer edge of the heat-bonded part with the lid material heat-bonded to the container, the lid material can be separated into the outer lid and the inner lid from the peel start cut point, but peeling When the position of the start cut is displaced to the inside of the heat-bonded portion, the heat-adhesive resin layer of the lid material outside the peel start cut adheres to the container, so the grip is gripped and the lid material is peeled from the container. At this time, the lid material peels off from the container with the surface layer such as expanded polystyrene of the container adhered to the inner surface of the lid material, and the lid material is peeled off to the outer lid and the inner lid at the position where the peeling starts. It has a drawback that it cannot be separated and a problem arises in that a drainage hole cannot be formed in the inner lid.
