  • Dispenser pump head for controlling misdirection
    Patent number: 8584906
    Abstract: A pump head for a displacement pump used in a bottle dispenser and configured to minimize misdirection of solution dispensed through an orifice thereof. The pump head is an integrally molded one piece structure, having an elliptical outlet orifice that lies in a substantially horizontal plane, and having a major axis substantially twice that of the minor axis. The configuration and the positioning of the orifice minimizes clogging or coagulation of certain solutions, obscures such coagulation from view, and minimizes the misdirection of any dispensing through the nozzle orifice that would otherwise result from clogging or coagulation. The pump head is particularly adapted for use with displacement pumps employed in bottle dispensers and the like.
