ABSTRACT:
Containers, particularly insulated containers are disclosed consisting essentially of a container body filled with a pump mechanism and featuring a flexible bell shaped member, immersed in liquid and equipped with disc valve. This bell shaped member is compressed whenever the actuating button is pressed, thereby forcing the liquid contents of the container to flow out through the pipe up to the pouring spout. A flexible tube is automatically squeezed shut when the bottom returns to its uppermost position.
