Institute Guilfoyle

Robert P Seifert

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. The dispenser further includes a shield shaped to direct fluid released from the dispenser in a desired direction. When a sufficiently large force is applied to the dispenser, the weaker top or bottom wall of the vessel ruptures, or opens, at the concentration region of the seal. The released fluid is then directed by the shield in the desired direction.

Pressure-rupturable container seal having a fluid flow directing shield

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.
