PURPOSE:To propagate fluorescence to the edge parts of the container and to radiate the fluorescence by forming the container body of light transparent plastic and a fluorescent dye to absorb ambient direct light and dispersed light. CONSTITUTION:A case 1 is constituted of a light condensing resin formed by compounding the fluorescent dye with a synthetic resin. The projected light passes partly the inside of a plate material 10 like F2, F3, F4 when the projected light enters a plate member 10 consisting of the light condensing resin and is absorbed in the fluorescent dye having high purity. The ratio of the fluorescence to the entire projected light depends on the refractive index possessed by the plastic. Light is absorbed in the dye and photons are propagated to the edge parts 4 of the plate member 10 and are radiated. 1 The ambient light is absorbed and collected as the fluorescence at the edge parts 4 even in a relatively dark room. The container is thus visible from the outside. |
