A container, a method of and and apparatus for forming cuts in the container are disclosed. Weakening lines (18, 19) serving as cutting lines are formed on inside of the sealing portion and outside of the flange portion (13) of the container, and a non-sealing region (20) is formed at the position at which a part of the outer weakening line (14) is included. These weakening lines (8, 14) can be formed by rotating the container and bringing the notching blades into contact with the flange portion (13). |
