ABSTRACT:
A fluid container has a fixed delivery mechanism capable of moving a pusher piston forward to thereby discharge the contained fluid substance quantitatively through a discharge hole by a gentle push of a knob or cover and through a unidirectionally driven motion change mechanism. The container is capable of regulating the delivery amount by adjustment of the press stroke of a drive mechanism and also capable of squeezing out a large amount of the contained substance at one time by a short stroke push operation. Further embodiments of the container are provided having discharge action during both the press stroke and the return stroke by the recovery of a spring, whereby a double discharge amount is obtained and energy is saved.
