PURPOSE:To facilitate the marking while making a mark easy to see by means of bonding a marking plate on a package. CONSTITUTION:A metallic or glass-made flat plate flush with the surface of a base plate 2 is bonded on the peripheral part of a package bottom 9 whereon marking is to be performed. Through these procedures, marking itself as well as the wiping of split ink in case of a marking miss are facilitated; moreover a mark improving the color-contrast with marking ink is easy to see; package direction is easily discriminated; and conventional index mark may be made needless. |
