PULL-ACTIVATED FOAM PUMPS, DISPENSERS AND REFILL UNITS |
摘要 |
<p>Foam dispenser systems, pumps and refill units are disclosed herein. A refill unit for refilling a foam dispenser system comprises a container for holding a supply of foamable liquid and a foam pump connected to the container. The pump incorporates a simple and inexpensive valve arrangement to move liquid through the pump and to create the foam. For example, a liquid foam pump may include a housing and a valve stem that moves in two directions. The valve stem has an inlet liquid pathway and an outlet liquid pathway to convey liquid to a mixing. In addition, a moveable valve body is movable by the valve stem in a first direction to move the valve body to the first position to open a liquid inlet pathway, and moveable in a second direction to move the valve body to the second position to open the outlet liquid pathway.</p> |
