A portable soap dispenser, comprising: liquid soap; a housing including a reservoir that stores a volume of the liquid soap; a fluid passage comprising an inlet and an outlet; a motor disposed in the housing; a pump body having a pump body aperture; a pump in fluid communication with the reservoir, the pump configured to be driven by the motor and to encourage a flow of the liquid soap into the inlet and out of the outlet of the fluid passage, said pump including a pump mechanism disposed in the pump body and configured to be driven by the motor; a staging chamber in fluid communication with the pump mechanism, the pump body aperture being in fluid communication with the reservoir and the staging chamber; wherein the staging chamber is configured to receive a primed volume of the liquid soap, to retain the primed volume of the liquid soap for a period of time, and to dispense at least some of the primed volume of the liquid soap to the pump mechanism during operation of the dispenser; and a nozzle in fluid communication with the outlet of the fluid passage, the nozzle being supported by the housing and projecting outward from the housing so as to be at least partly visible to an observer outside of the dispenser; wherein the nozzle comprises a flange being configured to mate with an annular surface of the housing, thereby forming a generally liquid tight seal therebetween, characterised in that the nozzle comprises a duckbill valve including a first deflectable member and a second deflectable member with a slit therebetween, the first deflectable member and the second deflectable member being biased toward each other, thereby inhibiting soap from being dispensed from the dispenser until the bias has been overcome and in that the pump body aperture includes a sloped or angled surface arranged such that the pump body aperture is wider in cross-section near the exterior of the pump body than near the interior of the pump body and the pump body aperture is configured to facilitate the flow of liquid soap into the staging chamber and configured to allow a bubble formed by air present in the pump body to readily pass through the opening during priming of the pump. liquid soap; a housing including a reservoir that stores a volume of the liquid soap; a fluid passage comprising an inlet and an outlet; a motor disposed in the housing; a pump body having a pump body aperture; a pump in fluid communication with the reservoir, the pump configured to be driven by the motor and to encourage a flow of the liquid soap into the inlet and out of the outlet of the fluid passage, said pump including a pump mechanism disposed in the pump body and configured to be driven by the motor; a staging chamber in fluid communication with the pump mechanism, the pump body aperture being in fluid communication with the reservoir and the staging chamber; wherein the staging chamber is configured to receive a primed volume of the liquid soap, to retain the primed volume of the liquid soap for a period of time, and to dispense at least some of the primed volume of the liquid soap to the pump mechanism during operation of the dispenser; and a nozzle in fluid communication with the outlet of the fluid passage, the nozzle being supported by the housing and projecting outward from the housing so as to be at least partly visible to an observer outside of the dispenser; wherein the nozzle comprises a flange being configured to mate with an annular surface of the housing, thereby forming a generally liquid tight seal therebetween, characterised in that the nozzle comprises a duckbill valve including a first deflectable member and a second deflectable member with a slit therebetween, the first deflectable member and the second deflectable member being biased toward each other, thereby inhibiting soap from being dispensed from the dispenser until the bias has been overcome and in that the pump body aperture includes a sloped or angled surface arranged such that the pump body aperture is wider in cross-section near the exterior of the pump body than near the interior of the pump body and the pump body aperture is configured to facilitate the flow of liquid soap into the staging chamber and configured to allow a bubble formed by air present in the pump body to readily pass through the opening during priming of the pump.
