Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag-like raw noodle, soup, ingredient, etc., which is contained in a container, such as cup-shaped noodles, and the like. The present invention relates to a lid member with a hot water drainage hole, which is used for the purpose of draining hot water after pouring water for a certain period of time.

[0002]

2. Description of the Related Art Conventionally, like a noodle in a cup, a packaged raw noodle, soup, ingredient, etc. is taken out, the raw noodle is taken out of the bag, put in the container, poured with hot water and left for a certain period of time. As a container with a lid to be used after draining hot water, the outer lid and the inner lid are partially releasably laminated as described in Japanese Patent Laid-Open No. 2001-19059, and project outward to the outer peripheral edge. The cut portion is formed, and the inner lid is formed with a hot water cut hole cut at the peripheral portion facing the pick portion, and the inner lid cut is formed so as to define the region where the cut portion and the hot water cut hole cut are formed. There is known a lid member having a structure in which a release layer is partially formed so as to face the region where the melter hole cut is formed on the inner surface of the outer lid.

However, in the case of the above-mentioned lid member, the lid member attached to the mouth portion of the container by thermal bonding is peeled from the container by grasping the picked portion, and the inner lid is cut along the inner lid cut line to be large. When forming the opening at the same time when forming the hot water drain hole in the inner lid that is bonded to the container, the direction of peeling the lid material and the direction in which both ends of the inner lid are about to peel from the container match. At both ends of the lid cut, the outer lid does not peel off from the inner lid, but the inner lid adheres to the outer lid and then peels off from the heat-bonded portion, and the inner lid with the hot-water drainage holes adheres to the container. There is a drawback that the hot water cannot be drained in some cases because it will not be left in a standing state. In addition, there is a drawback in that it is difficult to peel off the inner lid, which is left in the state of being adhered to the container, when the inner lid is peeled off and removed from the container because there is no knob portion.
