Filed: 1992-12-22
Abstract: PURPOSE:To make the package visible in order to prohibit loading when solid photographic processing agents are stuck to the inside surface of the package by the collapse by moisture absorption by varying the color of the surface of the package in contact with the solid photographic processing agents from the color of the processing agents. CONSTITUTION:The package is so formed that the color of the surface thereof in contact with the solid photographic processing agents varies from the color of the processing agent. The solid photographic processing agents T are housed into the parts formed by blistering a part of a transparent resin material 1 to plural small container shapes and a seal 2 is adhered to constitute the hermetically sealed package. While the package is constituted to prohibit the permeation of moisture, the sealing is not perfect and, therefore, pinholes and ruptures arise and the moisture infiltrates the package in some cases. The solid photographic processing agents T housed in the package collapse by absorbing the moisture. The adhesion D is easily visible through the transparent resin if the collapsed solid photographic processing agents T partly adhere to the resin material 1 or the inside surface of the seal 2 of the package in such a case. The erroneous loading among kinds is prevented by varying the appearance of the package by kinds of the processing agents.
