ABSTRACT:
A valve assembly is disclosed for use in an aerosol spray can capable of spraying viscous materials or materials with large particulates without clogging or packing like traditional aerosol spray cans designed for spraying texture materials. The valve opening may be located at substantially any point between the bottom and the top of the container. The valve assembly includes a plurality of side-fitting dip tubes, a side-feeding mechanism, and at least one storage member connected, respectively, to at least one of the dip tubes, whereby texture material is dispensed when a central channel is aligned with a side conduit that is in flow communication with the dip tubes. This allows highly-viscous materials, such as a fire suppressant material, or materials having large particulates, such as stucco, as well as resin/catalyst or blowing-agent/urethane combinations to be sprayed from a single aerosol spray can without clogging.
