초록 ▼

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.

1. A foam dispensing system having inverted containers comprising: a dispenser housing;a replaceable refill unit inserted at least partially in the housing;the replaceable refill unit having a container; the container having a neck portion at the bottom of the container;a horizontal foam pump secured to the neck portion; the pump having an inlet orientated along an inlet axis;the pump having a liquid pump chamber;the pump having a stationary outlet orientated along an outlet axis;the pump having a fluid passage extending from the pump chamber to the outlet;wherein the inlet axis is offset from the outlet axis; andthe outlet axis is located closer to the front of the dispenser than the inlet axis;an actuator located within the housing; andan air compressor; the air compressor having an air passage to direct air into the fluid passage; wherein the air compressor has a cylindrical housing and the air passage is located at the bottom of the cylindrical housing. 2. The foam dispensing system of claim 1 wherein the container has a center axis and a center of the neck portion is positioned along the center axis. 3. The foam dispensing system of claim 2 wherein the outlet nozzle is located in the front 30% of the overall depth of the dispenser housing. 4. The foam dispensing system of claim 1 wherein the air compressor forms part of the replaceable refill unit. 5. A foam dispensing system having inverted containers comprising: a dispenser housing;a replaceable refill unit inserted at least partially in the housing;the replaceable refill unit having a container; the container having a neck portion at the bottom of the container;a horizontal foam pump secured to the neck portion; the pump having an inlet orientated along a vertical inlet axis;the pump having a liquid pump chamber;the pump having a stationary outlet orientated along a vertical outlet axis;the pump having a fluid passage extending from the pump chamber to the outlet;an actuator located within the housing; andan air compressor;the air compressor having an air passage to direct air into the fluid passage; anda one-way air inlet valve having a cracking pressure selected so that when the air chamber expands, fluid is drawn in through the outlet nozzle providing suck back prior to the one-way air inlet valve opening to allow air to flow into the air compressor chamber through the one-way air inlet valve. 6. The foam dispensing system of claim 1 wherein the container is a non-collapsible container and the pump includes a container venting valve. 7. The foam dispensing system of claim 6 wherein a portion of the container is exposed and not contained within the housing. 8. The foam dispensing system of claim 1 further comprising a lost motion connector. 9. The foam dispensing system of claim 1 wherein the refill unit further comprises a battery secured to the refill unit and the battery is removable with the refill unit. 10. The foam dispensing system of claim 1 wherein the container is a collapsible container and the housing includes a transparent window for viewing the collapsible container. 11. The foam dispensing system of claim 1 wherein the dispenser is configured to hold the refill unit at an angle with the top of the refill unit tilted toward the front of the dispenser. 12. A foam dispensing system having inverted containers comprising: a dispenser housing;a replaceable refill unit inserted at least partially in the housing;the replaceable refill unit having a container; the container having a neck portion at the bottom of the container;a horizontal foam pump secured to the neck portion; the pump having an inlet orientated along a vertical inlet axis;the pump having a liquid pump chamber;the pump having a stationary outlet orientated along a vertical outlet axis;the pump having a fluid passage extending from the pump chamber to the outlet;wherein the vertical inlet axis is offset from the vertical outlet axis; andthe vertical outlet axis is located closer to the front of the dispenser than the vertical inlet axis;an actuator located within the housing; andan air compressor; the air compressor having an air passage to direct air into the fluid passage; wherein the air compressor has a cylindrical housing and the air passage is located at the bottom of the cylindrical housing. 13. The foam dispensing system of claim 12 wherein the container has a center axis and a center of the neck portion is positioned along the center axis and the vertical outlet axis is positioned off of the center axis. 14. The foam dispensing system of claim 12 wherein the outlet nozzle is located in the front 30% of the overall depth of the dispenser housing. 15. A foam dispensing system having inverted containers comprising: a dispenser housing;a replaceable refill unit inserted at least partially in the housing;the replaceable refill unit having a container; the container having a neck portion at the bottom of the container;a horizontal foam pump secured to the neck portion; the pump having an inlet orientated along a vertical inlet axis;the pump having a liquid pump chamber;the pump having a stationary outlet orientated along a vertical outlet axis;the pump having a fluid passage extending from the pump chamber to the outlet;an actuator located within the housing; andan air compressor;the air compressor having an air passage to direct air into the fluid passage; anda one-way air inlet valve having a cracking pressure selected so that when the air chamber expands, fluid is drawn in through the outlet nozzle providing suck back prior to the one-way air inlet valve opening to allow air to flow into the air compressor chamber through the one-way air inlet valve. 16. The foam dispensing system of claim 15 wherein the refill unit further comprises a battery secured to the refill unit and the battery is removable with the refill unit.
