An apparatus for dispensing two flowable substances in a user-selectable ratio. The dispensing apparatus includes first and second containers for receiving flowable substances. Each container has a dispensing end and a second end which initially includes a piston, which is moveable only toward the dispensing end as the substances are dispensed. The dispensing apparatus also includes a manifold member having an inlet with a pair of inlet openings for removably receiving the containers. The manifold member is internally divided into two chambers for receiving the respective flowable substances. A pump member, which is moveable with respect to the manifold chamber, having an inlet end in fluid communication with the manifold chambers is provided. A selector member with a single opening is provided in fluid communication with the outlet end of the manifold member. Upon movement of the pump member by a user in a first direction from its initial position with respect to the manifold member, a predetermined measure of flowable substance is dispensed from the apparatus. The ratio of the dispensed substances is user variable from 100% of the first flowable substance and 0% of the second flowable substance when the selector member is in the first position, to 0% of the first flowable substance and 100% of the second flowable substance when the selector member is in the second position, to any desired ratio there between when the selector member is in an intermediate position.

An apparatus for dispensing two flowable substances in a user selectable ratio comprising: a first container for receiving a first flowable substance, the first container having a uniform cross section and including a first, generally open dispensing end and a second end which initially includes a piston which is movable only toward the dispensing end as the flowable substance flows out of the dispensing end; a second container for receiving a second flowable substance, the second container having a uniform cross section and including a first, generally open dispensing end and a second end which initially includes a piston which is movable only toward the dispensing end as the second flowable substance flows out of the dispensing end; a manifold member having an inlet end and an outlet end, the inlet end having a pair of inlet openings for removably receiving the dispensing ends of the first and second containers, the manifold member being internally divided by a divider into two chambers, a first chamber being in fluid communication with the dispensing end of the first container, for receiving the first flowable substance, and a second chamber being in fluid communication with the dispensing end of the second container, for receiving the second flowable substance, the outlet end having a pair of outlet openings corresponding to the inlet openings so that the first and second flowable substances from the first and second containers flow into their respective inlet opening, through the respective chambers and out of the respective outlet openings of the manifold member; a pump member having an inlet end in fluid communication with the first and second manifold chambers and having an outlet end the pump member being movable with respect to the manifold member; a selector member in fluid communication with the outlet end of the manifold member, the selector member having a single opening of a predetermined size and a predetermined shape extending therethrough, the selector member being selectably rotatable with respect to the outlet end of the manifold member from a first position, in which the selector member opening is in fluid communication with the outlet of the first chamber of the manifold member with the outlet of the second chamber of the manifold member being blocked by the selector member, through a plurality of intermediate positions, in which the opening of the selector member is in fluid communication with portions of the outlets of both of the manifold member chambers with the remaining portions of the outlets of both of the manifold member chambers being blocked by the selector member, to a second position, in which the opening of the selector member is in fluid communication with the outlet of the second chamber of the manifold member and the outlet of the first chamber of the manifold member is blocked by the selector member; and a single dispenser outlet opening in communication with the selector member whereby, upon movement of the pump member by a user in a first direction with respect to the manifold member from an initial, rest position, a predetermined measure of flowable substance is dispensed from the apparatus with the ratio of the flowable substance which constitutes the predetermined measure being selectively variable by the user from one hundred percent of the first flowable substance and zero percent of the second flowable substance when the selector member is in the first position to zero percent of the first flowable substance and one hundred percent of the second flowable substance when the selector member is in the second position to any desired ratio therebetween when the selector member is in an intermediate position and wherein when, upon movement of the pump member in a second direction with respect to the manifold member opposite to the first direction, one or both of the pistons are moved to cause one or both flowable substances to flow into the respective manifold member chambers to thereby fill both of the manifold member chambers with the respective flowable substances.
