Abstract
A dispenser is provided including a dispenser housing that receives disposable refill units that are to be replaced when empty. The dispenser housing includes an air compressor and an inflation plug. The inflation plug includes a needle having an outlet and further includes a vent valve in fluid communication with the outlet. The inflation plug is fluidly associated with the air compressor such that the air compressor selectively advances air to the vent valve and to the outlet of the needle. The disposable refill includes a container having an interior with a liquid portion and air portion therein. The container further includes a plug receipt, and the inflation plug of the dispenser housing engages the plug receipt such that the outlet of the needle communicates with the interior of the container. The air compressor injects air into the interior of the container through the outlet of the needle to increase the pressure inside the container, and the vent valve of the inflation plug opens if the pressure of the container rises above a set threshold.
