Abstract
A dispenser assembly is provided that has a rigid plunger with a ring-shaped protrusion. The protrusion contacts the inner wall of a flexible barrel to form a liquid-tight seal. Advantageously, the dispenser assembly does not require additional components, such as o-rings, and can be fabricated by injection molding techniques.
