Abstract
A sealing member for sealing an opening of a container is provided with a sealing face facing contents in the container. This sealing face is formed into a shape without being externally exposing during an unsealing operation of the sealing member. The container can include the opening sealed with the sealing member, and a seal taking-out hole for taking out the sealing member when the opening is unsealed. A sealing member can include a leader for pinching the sealing member when the sealing member is peeled off from the container, and the leader can be inserted through the seal taking-out hole so that an opening sealing-face of the sealing member is bent inside when the unsealing operation of the sealing member is performed. A convex protrusion having a shape such that a face of the sealing member can be bent can be mounted on the seal taking-out hole. The sealing member for sealing an opening of the container can be formed into a cylindrical shape with a flexible material, and a part of an outer peripheral face of the sealing member seals the opening.
