摘要:
A fluid dispenser has a cradle for holding a container of liquid to be agitated before dispensing in a downwardly inclined position towards the dispensing outlet and includes an arrangement for causing a wave-like motion to the contents of the container. The arrangement can include a rocking mechanism for the end of the cradle remote from the dispensing end or an arrangement for intermittently applying pressure to the wall of the container adjacent the dispensing end. The diminishing contents of the container may be compensated for.
