Patent ID: 6848601

Claim:
An aerosol system for mixing first and second materials, comprising: a first container assembly comprising a first container for containing the second material and a propellant material that pressurizes the second material, and a first valve assembly operable in an open configuration and closed configuration, the first valve assembly comprising a first valve housing defining a first housing chamber, and a first valve member defining a valve stem portion, where the first valve member is partly arranged within the first housing chamber with the valve stem portion extending out of the first valve chamber; a second container assembly comprising a second container for containing the first material, and a second valve assembly operable in an open configuration and a closed configuration, the second valve assembly comprising a second valve housing defining a second housing chamber, and a second valve member that defines a stem seat and is arranged substantially within the second housing chamber; and a coupler comprising first and second connecting portions, where the first connecting portion of the coupler defines a connecting chamber adapted to receive the valve stem portion of the first valve member; and the second connecting portion of the coupler defines a coupler stem portion, where the stem seat of the second valve member is adapted to received the coupler stem portion; whereby when the first and second connecting portions engage the first and second valve assemblies and the first and second container assemblies are displaced towards each other, the first and second valve assemblies are placed in the open configuration to allow a portion of the propellant material and at least a portion of the second material to flow into the second container such that the first and second materials are mixed in the second container; and the mixture of the first and second materials is dispensed from the second container through the second valve assembly.
