Abstract
A fluid dispenser having a fluid container, a spout, and a pump for pumping fluid from the container out to the spout and having a piston for moving vertically along a piston axis. The spout has an inner end connected to the piston through a piston cap, with downward pressure on the piston cap moving the piston downward and actuating the pump. The spout also has a center section, an outer end with an outer bend, and an inner end with an inner bend, the piston has an upper end, and the spout inner end and the piston upper end have interengaging threaded portions coaxial with the piston axis. The piston cap has a body with a central opening coaxial with the piston axis and a lateral opening connecting with the central opening for receiving the spout, with the piston cap rotatable with the spout as the spout inner end is threaded into the piston upper end.
