20140054320 | OFF-AXIS INVERTED DISPENSERS AND REFILL UNITS - Exemplary embodiments of inverted dispenser systems and refill units are disclosed herein. An exemplary dispenser includes a dispenser housing and an actuating lever. A rack is engaged by the actuating lever. An actuator carriage is included that is movable back and forth in a linear motion. The rack is linked to the actuating carriage and the rack is movable back and forth in a linear motion. Movement of the rack toward the back of the dispenser causes the actuator carriage to move toward the front of the dispenser. | 02-27-2014 |
20140054322 | OFF-AXIS INVERTED FOAM DISPENSERS AND REFILL UNITS - An exemplary embodiment of a dispensing system includes a dispenser housing and a replaceable refill unit. The replaceable refill unit has a container that has a neck portion and a horizontal foam pump. The pump has an inlet orientated along an inlet axis and an outlet orientated along an outlet axis. A fluid passage extends from the pump chamber to the outlet. The inlet axis is offset from the outlet axis and the outlet axis is located closer to the front of the dispenser. An actuator is also located within the housing. In addition, an air compressor and an air passage to direct air into the fluid passage to mix the air with the fluid are included. The actuator is configured to drive the horizontal pump toward the front of the dispenser to dispense a fluid in the form of a foam. | 02-27-2014 |
20140263462 | SIMPLIFIED LIQUID OUTLET VALVES, PUMPS AND REFILL UNITS - An inverted refill unit for a dispenser is provided. The refill unit includes a liquid outlet valve in the form of an elastomeric member including a cylindrical side wall, an upper wall having an opening therein, and a valve member extending upwardly from the upper wall to selectively engage a valve seat. | 09-18-2014 |
20140367419 | FOAM CARTRIDGES, PUMPS, REFILL UNITS AND FOAM DISPENSERS UTILIZING THE SAME - Exemplary embodiments of foam cartridges, refill units for foam dispensers, and foam dispensers are disclosed herein. An exemplary foam cartridge for a foam pump that may be used in a refill unit includes a housing. The housing includes an upper cylindrical portion and a lower cylindrical portion. One or more air passageways are located through the upper cylindrical portion. The foam cartridge includes an interior cylindrical member having a dome. The interior cylindrical member is located at least partially within the upper cylindrical portion of the housing. One or more mixing passages located between the interior cylindrical member and the upper cylindrical portion of the housing, and one or more mix media are located at least partially within the lower cylindrical portion of the housing. | 12-18-2014 |
20150173568 | PUMPS WITH VENTS TO VENT INVERTED CONTAINERS AND REFILL UNITS HAVING NON-COLLAPSING CONTAINERS - Exemplary embodiments of refill units having foam pumps and non-collapsing containers are disclosed herein. In some exemplary embodiments, the refill unit includes a non-collapsing container and a foam pump. The foam pump includes a compressible air chamber. The foam pump includes a passage between the interior of the compressible air chamber and the interior of the container. A regulating valve regulates flow of air from the interior of the compressible air chamber to the interior of the container. | 06-25-2015 |
20150196170 | PUMPS WITH ANGLED OUTLETS, REFILL UNITS AND DISPENSERS HAVING ANGLED OUTLETS - Exemplary pumps, refill units and dispensers having angled outlets are disclosed herein. An exemplary refill unit for dispensing fluid on a hand includes a container and a pump. The pump includes an angled outlet passage. Fluid flowing out of the angled outlet passage is directed toward the palm of a hand when fluid is dispensed. | 07-16-2015 |
20150208877 | DISPENSERS AND REFILL UNITS HAVING COLLAPSIBLE OUTLET TUBES - Exemplary dispensers and refill units having collapsible outlet tubes are disclosed herein. An exemplary refill unit includes a container, a pump having an outlet that is movable in a reciprocating motion and a flexible tube. A first end of the flexible tube is in fluid communication with the outlet of the pump and a second end connectable to a dispenser. When the second end is connected to a dispenser, the second end is stationary and movement of the pump outlet away from the second end causes the pump to dispense fluid and movement of the pump outlet toward the second end causes the flexible tube to collapse. | 07-30-2015 |
20150297039 | MINI PUMP WITH COMPRESSIBLE AIR INLET CHAMBER FOR PROVIDING RESIDUAL SUCK-BACK - Exemplary dispensers, pumps and refill units are disclosed herein. An exemplary refill unit includes a container and a foam pump. The foam pump includes a liquid pump chamber, a compressible air inlet chamber and a compressed air inlet. The volume of the compressible air inlet chamber is less than the volume of air used to make a dose of foam. A one-way air inlet valve is located proximate the compressed air inlet. A piston is included that is movable within the liquid pump chamber and has a liquid seal member and an air seal member. The liquid pump chamber includes a liquid outlet into a center portion of the piston. One or more openings extend through the piston wall and provide a passage from the compressible air chamber to the center portion of the piston. The pump further includes mix media and an outlet. | 10-22-2015 |
