Device for dispensing two pasty substances in adjustable proportions

摘要

A dispensing device for dispensing two pasty substances in adjustable proportions from a deformable tube containing those substances in different regions within the tube. The device includes a body having two passages terminating in two outlets in the body, and a valve member pivotable within the body and having at least one through passage extending between an inlet on the surface of the valve member and a common outlet nozzle. The valve member has two extreme positions in which both passages in the body are fully closed or fully open, respectively. Pivotal positions of the valve member between these two extremes determine the degree of alignment of the inlet in the valve member with at least one of the outlets, so that the amount of substance dispensed through the partially covered outlet can be varied while the amount of substance dispensed through the other outlet remains constant.
