The end part (10) of the sealed container having the forward end part (1), the joint part (4), and the connection part (3) is formed separately from the body part (2). When force is applied to the forward end part (1) laterally to its center axis (5), the joining part (4) is broken, the head part of the truncated cone-shaped connection part (3) is exposed to the outside, and the space part (13) of the connection part is opened. |
