<P>PROBLEM TO BE SOLVED: To enable a residual amount of stored liquid to be detected even if a position of a bottom plate raised as the stored liquid is decreased cannot be seen, in a bottom raising container with a pump where the container is made opaque to protect the stored liquid against ultraviolet rays and the like. <P>SOLUTION: This bottom raising container with a pump has a liquid sucking pump at the upper part of an opaque container and has a bottom plate within the lower part of a body part of the container to eliminate a negative pressure formation within the container while being slid upwardly. The container 1 is made such that the upper part of a transparent body part 2 is provided with a colored part 7, the outer surface of the body part is covered by a light shielding layer 8 and the lower end of the body part is provided with an inward flange 4, the bottom plate 9 can be shielded against light and the inner part of the body part is seen through a flange hole 4a of the inward flange to enable the colored part 7 to be seen when the bottom plate rises up to a location near its upper limit. <P>COPYRIGHT: (C)2007,JPO&INPIT |
