Abstract
A dispenser for fluids includes an elastic bladder having an open end and a closed end and includes a bladder mounting structure for maintaining the bladder in tension. The bladder mounting structure includes a fixed structural element having a convex curved surface. The mounting structure also includes mounting elements for fixing the two ends of the bladder relative the curved surface so that bladder is stretched over the curved surface. A flow controller communicates with the open end of the bladder to regulate the flow of fluid from the bladder. The flow controller includes a body having a fluid flow path through it. A shutoff element in the fluid flow path controls the cross-sectional flow area of the flow path. Movement of the shutoff element is controlled by a mechanism sealed from the fluid flow path.
