ABSTRACT:
A refill unit for a fluid container is provided. The unit has a housing defining a fluid path in fluid communication with an outlet and configured to be operatively engaged with the fluid container, a fluid reservoir having an ejection port arranged in fluid communication with the fluid path inside the housing, and a plunger having a toothed thread which engages with a screw thread provided in an internal wall of the housing, the ejector having a drive gear so that actuation of the drive gear imparts rotation to the toothed thread so as to rotate the plunger within the screw thread of the housing to incrementally eject fluid from the fluid reservoir when the drive gear is actuated by operative engagement of the fluid container with the housing.
