Slightly above a rupture-intended line 2, a peripheral surface of a projection portion 103a of a stopper cap 103 is pushed in a direction from an outer side to an inner side (in an arrow direction). The stopper cap 103 is pushed over on the principle of leverage in an oblique direction with, as a fulcrum P, the side (the back side) opposite in a circumferential direction to the side (the near side) at which a pushing force PW acts, so that an intermittent portion is ruptured due to bending of the flexible stopper cap 103. Then, a residual area Z1 remains at the syringe 101 side, and a separation area Z2 is separated together with the stopper cap 103 from the syringe 101 to perform unsealing. Thus, a syringe label which allows for easy unsealing along the intermittent portion and with which an unsealed state is easily confirmed, and a drug solution-filled syringe using the label, are provided. |
