This container is designed so that the hot water discharge passage and the hot water outlet are not clogged due to the contents when the hot water is cut off, and the hot water can be smoothly cut, but a molded lid with a complicated structure is used. Therefore, not only is the cost high, but the possibility that the main body comes off from the molding lid and falls during the hot water draining operation cannot be completely denied.

The lid material with hot water cutting function and the container with hot water cutting function described in Patent Document 3 are lid materials for sealing to the flange portion of the container body, and the pouring gate portion and the hot water cutting portion are located at positions facing the lid material. A partial release coating layer is provided on a predetermined portion of the hot water cut opening for separating the cover material into an upper cover portion and a lower cover portion; A hot water slicer characterized in that a hole and a half-cut for peeling start that triggers peeling to an upper lid part and a lower lid part are formed so as to be located on a flange part of a container body to be sealed with a lid material.
