ABSTRACT:
This foam dispensing device includes a flexible container for foamable liquid, having a discharge opening at one end. A foam producing assembly is housed within the container, the assembly including a self-supporting porous member of rigid material held within the neck of the container and a tubular member of non-porous material having one end extending into the porous member and the other end extending into the interior of the container. Fluid mixing within the porous member is facilitated by flow restriction, and an air return facilitates rapid container recovery.
