Abstract
A flexible fluid dispenser includes a flexible fluid-containing vessel which has a seal which seals a top wall of the vessel to a bottom wall and is shaped to concentrate in a region thereof forces resulting from pressure generated by applying a force to the dispenser. When the resulting force is sufficiently large, the weaker top or bottom wall of the vessel breaks, or opens, at the concentration region of the seal. The opening has dimensions which approximate the dimensions of the force-concentrating region of the seal.
