2. Description of the Related Art As seen in Japanese Utility Model Publication No. 62-21581, a lid body attached to a container body for storing instant noodles has a recessed groove provided on an outer peripheral portion of an opening edge of the container body. Most of them are designed to be attached to the body of the container by fitting them into the brim-shaped part provided on the part, and this kind of lid is made of a thin synthetic resin sheet of polystyrene or polypropylene. It is often manufactured by plate molding. When stacking a large number of lids of this shape, pressing the suction tool onto the upper surface of the top lid to suck it, and then raising the suction tool to pick up the lids, stacking is performed. There are cases where two or more lids are picked up at one time while the fitted lids are fitted to each other via the recessed groove forming portions. Therefore, conventionally, a blocking portion is provided on the inner wall portion of the recessed groove of each of the stacked lids, and the fitting groove of the upper lid is fitted into the recessed groove forming location by this blocking portion. A so-called blocking portion for preventing such a situation is provided. In the conventional lid, the blocking portion is a protrusion protruding toward the outside of the recessed groove (that is, the center side of the lid) on the inner wall portion of the recessed groove except the hot water outlet forming portion. It was formed by providing a part. On the other hand, for instant foods such as noodles that need to be returned with hot water, in order to allow the hot water in the container body to be discarded in a short time by turning the container upside down, It is desirable to make the internal space as wide as possible so that hot water can collect easily at the hot water outlet.
