Blower-attached product applicator, and method for dispensing a product into a moving airstream

A combination comprising a portable air blower adapted for supplying a discharge airstream through an elongated blower tube and a product applicator secured to said air blower, wherein said product applicator comprises:

• an adapter nozzle assembly located at a distal end of said blower tube, and comprising a substantially hollow housing and a discharge nozzle located inside said housing, and said housing having a discharge end and a connecting end adapted for being arranged inline with the discharge airstream supplied by said air blower;
• a product storage container located proximate said housing, and designed for storing a product to be discharged through said discharge nozzle;
• an air transfer conduit having a first open end communicating with an inside of said housing upstream of said discharge nozzle, and a second open end extending inside of said product storage container and adapted for residing above a surface of the product stored inside said product storage container;
• a supply conduit having a first end fluidly connected to said discharge nozzle inside said housing, and a second open end communicating with the inside of said product storage container at a point below the surface of the product stored inside said product storage container, whereby the discharge airstream passing inline through said housing and across the first open end of said air transfer conduit generates a pressure differential urging the product outwardly from said product storage container through the second open end of said supply conduit to said discharge nozzle;
• a flow regulator adapted for selectively adjusting a supply of product from said product storage container through said supply conduit to said discharge nozzle;
• said product storage container defining first and second spaced apart flow ports fluidly communicating with said air transfer conduit and said supply conduit;
• a hollow air tube located inside said product storage container at the first flow port,
• and wherein said air tube fluidly communicates with said air transfer conduit to direct a flow of air between the inside of said product storage container and said blower tube;
• a fluid release valve located inside said product storage container at the second flow port;
• and
• a flow manifold having first and second hollow manifold tubes fluidly communicating with respective first and second flow ports of said product storage container, and wherein one of said first and second manifold tubes automatically opens said fluid release valve upon attachment of said product storage container to said housing.
