Apparatus for dispensing two sprayable substances in a user selectable ratio

An apparatus for dispensing two sprayable substances in a user selectable ratio comprising:

• a first pressurized container for holding a first sprayable substance, the container including a dispensing end;
• a second pressurized container for holding a second sprayable substance, the second container including a dispensing end;
• a manifold member having first and second inlet openings and an outlet opening, the inlet openings being configured for removably receiving the dispensing ends of the first and second pressurized containers, the manifold member including two passages, a first passage being in fluid communication between the first inlet opening and the outlet opening, and a second passage being in fluid communication between the second inlet opening and the outlet opening;
• a selector member in fluid communication with the first and second passages in 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 opening in the manifold member from a first position, in which the selector member opening is in fluid communication with the first passage with the outlet of the second passage 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 both passages with the remaining portions of the outlets of both of the passages being blocked by the selector member, to a second position, in which the opening of the selector member is in fluid communication with the second passage and the first passage is blocked by the selector member;
• and
• an actuator having an inlet opening in communication with the selector member and an outlet opening whereby, upon activation of the actuator a predetermined measure of sprayable substance is dispensed from the apparatus with the ratio of the dispensed substance being selectively variable by the user from one hundred percent of the first sprayable substance and zero percent of the second sprayable substance when the selector member is in the first position to zero percent of the first sprayable substance and one hundred percent of the second sprayable substance when the selector member is in the second position to any desired ratio therebetween when the selector member is in an intermediate position.
