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.

1. A refill unit comprising: a container;a pump;the pump having a pump outlet;the pump outlet movable in a reciprocating motion; anda flexible tube; wherein a first end of the flexible tube is in fluid communication with the pump outlet and a second end of the flexible tube selectively connects to a dispenser housing;wherein when the second end of the flexible tube is connected to a dispenser housing, the second end is stationary; andwherein movement of the pump outlet away from the second end of the flexible tube causes fluid to dispense and movement of the pump outlet toward the second end causes the flexible tube to collapse;wherein when the pump outlet moves to dispense fluid, the first end of the flexible tube is offset vertically and is offset horizontally from the second end of the flexible tube. 2. The refill unit of claim 1 wherein when the flexible tube collapses it has at least one pinch point sealing the pump outlet from the second end of the flexible tube. 3. The refill unit of claim 1 wherein when the flexible tube collapses it has at least two pinch points sealing the pump outlet from the second end of the flexible tube. 4. The refill unit of claim 1 wherein the reciprocating motion of the pump outlet is upward and downward. 5. The refill unit of claim 4 wherein upward movement of the pump outlet causes fluid to dispense. 6. The refill unit of claim 1 wherein the flexible tube comprises an elastomer. 7. The refill unit of claim 1 wherein the flexible tube includes at least one predetermined flex point. 8. The refill unit of claim 1 wherein the flexible tube includes at least two predetermined flex points. 9. The refill unit of claim 1 wherein the flexible tube stretches during movement of the pump outlet away from the second end of the flexible tube. 10. The refill unit of claim 1 further comprising a first portion at the second end of the flexible tube that is more rigid than a second portion of the flexible tube. 11. The refill unit of claim 10 wherein the first portion at the second end of the flexible tube is a different material than the second portion of the flexible tube. 12. The refill unit of claim 1 wherein movement of the pump outlet towards the second end of the flexible tube causes the flexible tube to pinch to a closed position in one or more predetermined points. 13. The refill unit of claim 1 wherein when the pump outlet moves to dispense fluid, the flexible tube extends at an axis that does not extend along a horizontal axis and does not extend along a vertical axis. 14. The refill unit of claim 1 wherein when the pump outlet moves to a rest position, the flexible tube forms a reservoir between a pair of pinch points. 15. A refill unit comprising: a container;a pump;the pump having a pump outlet;the pump outlet moves in an upward motion to dispense fluid and moves to a downward position during a resting state; anda flexible tube;a first end of the flexible tube connected to the pump outlet;a second end of the flexible tube that selectively connects to a dispenser housing; wherein when the second end of the flexible tube is connected to a dispenser housing, the second end is stationary; andwherein movement of the pump outlet away from the second end of the flexible tube opens a path through the flexible tube to dispense fluid and movement of the pump outlet toward the second end causes the flexible tube to close;wherein when the pump outlet moves to dispense fluid, the flexible tube extends at an axis that does not extend along a horizontal axis and does not extend along a vertical axis. 16. A dispenser comprising: a dispenser housing;an actuator;a container;a pump;the pump having a pump outlet;the pump outlet moves in an upward motion to dispense fluid and moves to a downward position during a resting state; anda flexible tube;a first end of the flexible tube connected to the pump outlet;a second end of the flexible tube that selectively connects to a stationary portion of the dispenser housing; wherein movement of the pump outlet away from the second end of the flexible tube opens a path through the flexible tube to dispense fluid and movement of the pump outlet toward the second end causes the flexible tube to pinch to a closed position in one or more locations;wherein when the pump outlet moves to the upward most position, the first end of the flexible tube is offset vertically and is offset horizontally from the second end of the flexible tube. 17. The dispenser of claim 16 wherein the flexible tube pinches to a closed position in one or more predetermined points. 18. The dispenser of claim 16 wherein when the pump outlet moves to a rest position, at least a pair of pinch points are formed in the flexible tube and a reservoir is formed between the pair of pinch points.
