Abstract
Abstract This invention is directed to a liquid storage container. More particularly, this invention is directed to a liquid storage container that can be connected or attached to a spray pump which comprises two separate chambers to hold liquid components, each chamber having a take-up tube which leads to a mixing chamber contained within a movable member attached to a movable external selector, the member having openings therein, wherein, when the external selector is moved, the movable member attached thereto moves in a manner such that the ratio of the quantities of liquid components from the chambers varies.
