Exemplary embodiments of dispensers for dispensing a liquid from a refill unit that has a container and a resilient dome pump are disclosed herein. Some embodiments include a plurality of rollers that rotate about a common axis to compress a dome pump and a holder for holding a refill unit having a container and a resilient dome pump. During operation, when a refill unit is located within the holder, rotation of the rollers about the common axis causes a roller to compress the resilient dome pump as the roller passes over the resilient dome pump to dispense liquid, and the resilient dome pump expands to its original position once the roller passes to draw in liquid. |
