PROBLEM TO BE SOLVED: To prevent the unjust refilling with ink by providing a means detecting the ink absorbed by the ink absorbing member communicating with a branch passage to the ink absorbing part connected to the branch part of an atmosphere communication route. SOLUTION: A display part 3 is composed of a container having an ink absorbing member 10 provided therein and this container is composed of a transparent plastic excepting a part. This part is a pattern formed by an opaque part having a color almost same to that of the ink absorbing member and, herein, this pattern is a term said to be an unjust filling product. When an unjust user injects ink 12 from the atmosphere communication hole 4 by using a syringe 11, the ink 12 is passed through a branch part 8 from the atmospheric communication hole 4 to be absorbed by the ink absorbing member 10 in a display part. When the ink 12 is absorbed by the ink absorbing member 10, the transparent part of the display part 3 becomes an ink color and the opaque part is conspicuously looked and the term of 'unjust filling product' can be clearly discriminated. |
