DISPOSABLE DISPENSING SYSTEM COMPRISING A COLLAPSIBLE CONTAINER, A DISPENSER AND A METHOD FOR DISPENSING LIQUID FROM SUCH DISPENSING SYSTEM

A disposable dispensing system includes a collapsible container for liquid material sealingly connected to a pump. The pump includes a housing forming a chamber and a dispensing opening, wherein the pressure in the chamber may be varied for pumping liquid from the container to the chamber, and from the chamber to the dispensing opening. A regulator is fixedly arranged in the chamber for regulating flow of liquid between the container and the chamber, and between the chamber and the dispensing opening. The pump may assume a closed position, in which a volume of liquid is drawn from the container to the chamber by a negative pressure created in the chamber, and a dispensing position, in which a volume of liquid is drawn from the chamber to the dispensing opening.
