Abstract

A manual spray dispenser for dispensing a mixture of two compositions comprises a container having a first and second chamber and a single dispensing spray outlet. At least one of the chambers has a separator in the form of a pouch for physically separating the contents of the container from an interior surface of the chamber. One of the first and second chambers contains a first composition and the other contains a second composition. The dispenser further contains a dispensing system for simultaneously dispensing the first composition and the second composition, mixing the two compositions together, and dispensing a mixture of the two compositions from the container under pressure. An aerosol propellant is between the separator and the interior surface of the at least one of the first and second chambers for pressurizing the composition in the pouch for dispensing the contents thereof through the dispensing system under pressure.
