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.

For use with a deformable tube containing two pasty substances in two different regions within the tube, a device for dispensing the two pasty substances in adjustable proportions, the device comprising: a body for mounting on the tube, the body having two passages communicating respectively with the two regions with the tube, each passage terminating in an outlet located in a surface of the body, a valve member mounted for pivotal movement with respect to the body about an axis perpendicular to the direction of flow of the substances through the passages in the body, a surface of the valve member being cylindrical and having an axis of curvature colinear with the pivot axis of the valve member, the cylindrical surface fitting tightly against the surface of the body in which the outlets are located, and at least one through passage in the valve member extending between an inlet, located in the cylindrical surface, and a common outlet nozzle for both pasty substances, the valve member having one extreme position in which its cylindrical surface closes both outlets and another extreme position in which the outlets are open to a maximum extent to the common outlet nozzle, and the pivotal position of the valve member between the two extreme positions determining the degree of alignment of the inlet with at least one of the outlets, the non-aligned portion of that outlet being closed by the cylindrical surface, whereby the ratio of the open areas of the outlets, and hence the proportions of the two pasty substances reaching the common outlet nozzle, depends upon the pivotal position of the valve member with respect to the body.
