The invention is characterized by a pair of marks provided across said scratches. A characteristic of this invention, that is, a pair of marks provided as above, makes it possible to identify the positions of scratches correctly and easily and, further, makes it needless to pinpoint the scractches themselves, thereby enabling the ampule to be snapped open at a portion between paired marks even when no attention is paid to the positions of scratches.</p> |
