<p>PROBLEM TO BE SOLVED: To certainly maintain an opening for pouring hot water and to simplify operations for cooking by a method wherein a covering member having a nipping tab at a part of its outer peripheral edge is provided with a holding means which is provided at its outer peripheral edge on a position that becomes opposite to the nipping tab when the covering member is curled up with the nipping tab being nipped and an opening of a container is opened half. SOLUTION: A covering member 1 is curled up with its nipping tab 2 nipped with fingers and separated from a container main body 30 to unseal an opening of the container to a half and an opening A for pouring hot water in is formed. At this time, wedge-like notches formed at both sides of a root of the nipping tab 2 are engaged with an indented notch 3 formed at the outer peripheral edge of the covering member 1 on a position opposite to the nipping tab 2, and the state of unsealing is held for the covering member 1. After hot water is poured through the hot water pouring opening A into the container main body 30, the nipping tab 2 is relieved from the engagement with the indented notch 3, and the hot water pouring opening A is closed again with the covering member 1 having elastic deformativeness automatically restored. Furthermore, the covering member 1 is curled up again with the nipping tab 2 nipped with fingers and the container opening is opened completely for eating of contents such as noodles.</p> |
