Foam Deceleration Tube for Aerosol Herbicide Dispenser

Abstract

This device is an element of the nozzle of an aerosol residential herbicide dispenser designed to reduce the speed at which the herbicide is delivered to an unwanted plant, preventing splattering and misapplication of the chemical to surrounding desired plants.

1 . I believe that use of this device provides a new and superior method of weed control in a mature residential landscape, and that this method of herbicide foam deceleration is a unique invention. While previous dispensers allow foam to be directed at a specific plant, they do not attempt to reduce the speed at which foam is delivered. With such dispensers, the foam exits the container in a narrow stream but so rapidly that it is very difficult, even at close range, to confine the herbicide to a specific plant; the result is that surrounding desirable plants are often poisoned and destroyed. However, there are many occasions when an undesired plant is found growing in the midst of lawn grass, ground cover, or shrubbery. I have found that close range application of herbicide using my invention is easily performed and accurate enough to kill such weeds without creating unsightly brown spots in the landscape.
