20090108023 | Dispenser pump head for controlling misdirection - 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. | 04-30-2009 |
20090188994 | Atomizing foam pump - An antomizing foam pump creates atomized droplets of a foamable liquid in air in a compression chamber. The compression chamber is then collapsed to force the droplets and air through a mesh screen to create a foam product. | 07-30-2009 |
20090236370 | High velocity foam pump - A foam pump including a pump housing with a liquid chamber in fluid communication with a foamable liquid filled container and an air chamber in fluid communication with a high pressure air source through an air inlet. The foam pump also includes a dispensing tube having a wiper seal post with a closed distal end positioned within the pump housing, and an outlet tube with an open distal end positioned outside the pump housing. The wiper seal post includes at least one inlet hole in fluid communication with the liquid chamber, and a check valve near the second open end. The foam pump further includes at least one foam screen in the open end of the outlet tube, a wiper seal slidably positioned around the wiper seal post and in sealing contact with the pump housing and the wiper seal post, and a spring bias to bias the wiper seal in an unactuated position. The wiper seal forms a movable barrier between the liquid chamber and the air chamber and is adapted to slide axially along the wiper seal post past the inlet hole when actuated by high pressure air, thereby allowing the high pressure air to enter the dispenser tube and cause mixing of said air and foamable liquid within the dispensing tube. The mixture is then expelled through the check valve and the foam screen. | 09-24-2009 |
20090314806 | TWO-STROKE FOAM PUMP - A two-stroke foam pump includes a piston housing and a piston assembly retained therein, the interaction of the piston housing and piston assembly defining a compressible mixing chamber. Movement of the piston assembly within the piston housing in one direction increases the volume of the compressible mixing chamber to draw liquid and air therein, and movement of the piston assembly within the piston housing in a direct opposite thereto decreases the volume of the compressible mixing chamber to expel liquid and air from the compressible mixing chamber as a foam product. | 12-24-2009 |
20100206896 | WIPES DISPENSER WITH ANTI-ROPING AND ANTI-FALLBACK FEATURES - A wipes dispenser includes a container having an interior holding a plurality of wipes.
