PURPOSE:To prevent accident caused by oxidation of contents, by detecting an inorganic or organic solvent by a pigment or a dye, which is colored when it is dissolved or dispersed in a solvent comprising an inorganic or organic material. CONSTITUTION:In the case of application to a container constituting body A, in which a content 8 is inputted, a member layer 4, which is liable to absorb liquid, is bonded between a surface member layer 2, on which a printing surface 1 is provided, and a back surface member layer 7 with bonding agents 3 and 5. Thus a coloring laminated member B is constituted. The member B is laminated on the outside of the constituting body A and used. A coloring member layer 6 is printed on the layer 4 comprising paper and a white opaque polymer layer. Hydrophilic property and lipophilic property, which are opposite to the layers 4 and 6, are provided in the bonding agents 3 and 5. The layers 2 and 7 are formed by transparent plastic film having excellent humidity resistance. An ordinary water soluble dye and the like are used for the layer 6. A small hole reaching the content 8 is provided from the outside through the members A and B. Then the layer 6 is colored by the content 8. |
