Abstract

Abstract ABSTRACT OF THE DISCLOSURE A fluid dispensing device for dispensing measured amounts of fluid from a sealed vessel having a flexible, discharge tube capable of providing a selective choice of at least two measured quantities of fluid that can be dis-pensed at any given time but where it is possible to adjust the device so as to provide different choices of measured quantities of fluid which can be dispensed, but for all possible choices, always ensuring that an unacceptable amount of fluid does not drip from the tube after the desired amount of fluid has been dispensed. The invention also provides a device with an acceptable amount of drip even when there is a single fixed quantity of fluid to be dis-pensed or when the amount of fluid to be dispensed is man-ually controlled by the operator by continuously closing a switch each time the device is used.
