ABSTRACT:
A dispenser for liquid is provided having a relatively stiff or rigid container above a resiliently deformable reservoir structure. The container is coupled to the reservoir structure and the container has a bottom outlet inside the reservoir structure which also includes a discharge structure leading from the inside to the outside of the reservoir structure. Liquid is dispensed when the user causes relative movement between the container and the reservoir structure to increase the pressure in the reservoir structure and to thereby force liquid from the reservoir structure through the outlet passageway.
