To manage a bar code of a vial on which there exists almost no location for sticking a label seal except a label seal for a commodity, and to prevent the vial from being mistaken at the time of administering work or the like.

For sticking a label seal L on which kind, quantity and the like of a medicine fluid are printed on the vial B, the label seal L with approximately the same diameter as the diameter of the bottom face of the vial B is stuck only on the outer periphery of the bottom face B3 of the vial B. It is possible thereby to hold the label seal L in a plane-like state regardless of the shape of the bottom face of the vial B, and to prevent the bar code printed on the surface of the label seal L from being misread.
