The effect of providing the notch 9 will be described later. Modification (Fig. 22)
  • FIG. 22 shows a modification of the fourth embodiment. This modification is different from the fourth embodiment in that two substantially parallel outer peeling start cuts 3a and 3b are formed at regular intervals inside the knob 2. A solid release layer 14a is formed in a region facing the two peeling start cuts 3a and 3b.
