Abstract
The metered dual dispenser cap is for dual compartmented squeeze type containers which separately contain two distinct materials. The metered dual dispenser cap has a lower portion which is reciprocally attached to an upper portion. The lower portion has two inlets, each regulated by one way valves. The two inlets lead to two chambers which in turn lead through two outlet shafts to two dispensing outlets in the upper portion. The flow from the two chambers to the two dispensing outlets is regulated by two one way valves which are controlled by a push button on top of the cap. The volume expansion of the chambers, as the upper portion is pulled away from the lower portion, may be determined from optional scale gradations on the outer male wall. The scale gradations are increasingly exposed as the upper portion is pulled away to increase the volume in the chambers.
