Abstract
A foam dispenser utilizes a deformable reservoir, a foamable fluid and air or other gas; a discharge device and an arrangement for producing foam that includes a plurality of mesh screens. When the dispenser is operated, air from inside the dispenser is mixed with the fluid to produce foam. The dispenser employs a shaped and resilient deformable seal for use in quickly recharging the container with air used in the creation of foam. The dispenser also advantageously employs an integrally molded swirl manifold to create a foam of excellent quality and consistency.
