  However, in the case of the lid member configured as described above, when the consumer uses the container to which the lid member is attached, the consumer has an opening knob and a hot water outlet opening knob on the periphery. Rather than opening the lid material, if you accidentally grab the handle for opening the hot water outlet and peel it off and have formed the hot water outlet at the end, it has the disadvantage that the instant fried noodles will be fully steamed and you will not be able to cook In the case where there is a deviation between the printing position of the release agent and the half cut position for forming the hot water outlet, when the surface sheet is peeled from the base material, the portion surrounded by the half cut for forming the hot water outlet is In some cases, the base material may not be reliably pulled out in a state where the base material is adhered to the surface sheet. In this case, there is a disadvantage that a predetermined hot water outlet is not formed on the base material.

  The object of the present invention is to hold the knob of the lid attached to the container and peel the outer lid about half of the container mouth to form an opening, which can be steamed and cooked with a lid after pouring. Further, it is to provide a lid member with a hot water cut hole that can form a hot water cut hole by further complete peeling and discharge hot water in the container from the hot water cut hole.

  The outer lid and the inner lid have a structure in which the outer lid and the inner lid are detachably stacked, and the outer peripheral edge is formed with a knob portion protruding outward, and the inner lid is adjacent to the inner side of the knob portion. A peeling start cut is formed, a plurality of hot water cuts are formed on the peripheral edge opposite to the knob, and an opening cut is formed in a region between the hot water cut and the outer lid peeling start cut, On the inner surface of the outer lid, a second release layer having a high peel strength is formed in a region having a predetermined width in a direction perpendicular to the line connecting the knob and the center of the lid member between the cut for hot water and the cut for opening. A first release layer having a low peel strength is formed in a region excluding the region where the second release layer is formed, the region surrounded by the opening notch, and the tip region of the knob, and the first release layer is connected to the network. The mold release is performed so that the second release layer has a dot area ratio of 60 to 85% so that the dot area ratio is 70 to 100%. It is the hot water cutting perforated lid, characterized in that is formed of a resin.

  The opening cut is configured to have a shape having a protruding portion protruding inward in the vicinity of the knob.

  After the inner lid and the outer lid are laminated, the hot water cut, the opening cut, and the outer lid peeling start cut through the inner lid by half-cut from the inner surface of the inner lid. It is the formed structure.

  By using the lid material with a hot water cut hole of the present invention, it is attached by heat bonding to a container containing instant fried noodles, sauces, etc., grasping the knob, peeling the outer lid about half of the container mouth, and opening a large opening It can be formed, and the lid material can be completely peeled off to form a hot water cutting hole. With the large opening formed, the individually wrapped sauce etc. is taken out of the container and instant fried noodles in the container Hot water is poured into the container, and the lid material that has been half-opened is closed and allowed to stand for a certain period of time to prepare the instant fried noodles, and then the lid material is completely peeled off to form a hot water cut hole for hot water cutting.

  In the inventions according to claims 2 and 3, the outer lid is peeled off to about half of the container mouth in the region of the first release layer by grasping the knob, and peeling is performed when reaching the region of the second release layer. Since it becomes heavier, peeling of the lid material can be stopped in a half-open state.

  In the invention according to claim 4, it is easy to remove the inner lid remaining in a state where the outer lid is completely peeled off and adhered to the container mouth portion by grasping the protruding portion and peeling it from the container.
