Abstract
A fluid dispenser operable between opened and closed positions is adapted for attachment to a flexible bag that contains a liquid, particulate matter or other fluid material, where an opening is provided through a wall of the bag into an interior of the dispenser. The dispenser is initially closed to fluid flow, for the purpose of storage and shipping, by a diaphragm that is cut the first time the dispenser is operated to its opened position. A specially designed diaphragm cutting track and cooperative knife shape cause a cut diaphragm flap to be pushed out of the fluid flow path through the dispenser.
