Abstract

A vacuum bottle includes a pump dispenser for dispensing liquids from the temperature insulating interior without the need for removing the top or pouring. The pump dispenser employs a manually operated disk to pump air from a diaphragm into the bottle interior where it forces the liquid contents up a fluid tube and out a dispensing spout. A plurality of spaced ribs improve the operation of the dispenser mechanism by preventing twisting of the disk during pumping.
