Abstract
A refillable dispenser for viscous compositions comprises a bottle having walls defining an upper cavity and a lower cavity, a viscous composition refill mechanism configured to allow viscous composition to enter the upper cavity when the refill mechanism is fluidly coupled to a viscous composition source and a viscous composition dispensing mechanism configured to allow viscous composition to be dispensed from the upper cavity to outside the bottle when the dispensing mechanism is actuated. A gasket configured to substantially seal the upper cavity from the lower cavity is provided wherein the gasket is capable of moving towards the upper cavity upon actuation of the dispensing mechanism and moving towards the lower cavity upon entrance of the viscous composition into the upper cavity.
