Abstract: A liquid-dispensing device is provided, which is simple in structure, has minimal space requirements, is operative with of a wide range of liquid consistencies, and is adapted for repeatedly dispensing a predetermined liquid volume from a liquid container. The device is particularly useful when contact between the liquid and the atmosphere is to be minimized, for example, when the liquid is a carbonated or naturally effervescent drink, fresh juice, or wines. Similarly, the device is useful when contact between the liquid and a user is to be avoided, for example, when the liquid is harsh or poisonous. The device is formed of common and easily available materials; it is inexpensive to produce and simple to operate. It is adapted for use with existing liquid containers, such as bottles, jerricans, beer kegs, or barrels, and makes pouring an easy task for anyone, and in particular, for children, the elderly, and people with disabilities.
