Patent Application

The present invention relates generally to spray guards for fluid dispensers and more particularly to a method and device for spraying chemicals from a spray wand that provides “pin-point” accuracy and eliminates the chemical spray from drifting to unwarranted targets.
Weed control is a necessary part of everyday life. Weeds choke off the sunlight and nutrients from plants which are desirable. Pulling weeds from the ground is generally unsatisfactory because of the un-ability to completely remove all the roots of the weeds. Chemical spraying is desirable because once weeds have been sprayed with a sufficient quantity of chemicals the entire weed including the roots die off.
It would be desirable to treat weeds when there is absolutely no wind. However, this atmospheric condition is difficult to achieve and realistically, weeds spraying is done when there is little or moderate airflow. Even a small amount of airflow can interact with the chemical spraying by lifting the chemical spray from the end of the spray device and depositing the chemical spray on wanted plants. This misplaced chemical spray may be sufficient to kill the wanted plants. This of course defeats the purpose of spraying.
What is needed is a way to avoid the application of the misplaced chemical spray.
A spray device for spraying a fluid may include a reservoir to hold the fluid; a hose connected to the reservoir to convey the fluid; a handle to connect to the hose; a telescoping dispensing shaft connected to the handle allowing a more comfortable adjustment to the user, to convey the fluid; and a dome connected to the telescoping dispensing shaft to encapsulate the excess drift. The dome may be formed from one of translucent or clear material.
A spray device for spraying a fluid may include a trigger to control the flow of the fluid;
A spray device for spraying a fluid may include a fluid to control weeds.
A spray device for spraying a fluid may include a flexible hose.
A spray device for spraying a fluid may include the reservoir that may be adapted to hold pressurized fluid.
The invention may be understood by reference to the following description taken in conjunction with the accompanying drawings, in which, like reference numerals identify like elements, and in which:
The BOS “Stop Drift” Spray Wand allows the user to kill weeds in Planter Beds, Driveway cracks, Side Walk cracks, Curb cracks all the while preventing the excess liquid sprayed that usually turns into Vapor/Drift from reaching any unwarranted targets, such as Plants, Shrubs, Flowers, Grass, Children, Playground Toys, Dog Food Bowel and Water Containers. In the Landscape Industry, it is common knowledge that spraying weeds is part of the general contract for residential and commercial properties. The BOS “Stop Drift” Spray Wand may help reduce the insurance liabilities commonly caused by spraying chemicals of any kind around the public. However, part of the service contract for Landscape Crews Nationwide, when servicing commercial or residential properties is to maintain weeds in planter beds, concrete crack weeds on sidewalks, curbs, and around building, near the front door entry to buildings and in the foundation next to building, always subjecting the public to chemical drift. The BOS “Stop Drift” Spray Wand was designed to comfortably target the weed by placing the capsule/dome over the weed, encapsulating the entire weed target and pulling the trigger, releasing the liquid chemical on to the target. It has extendable a wand so that the length will adjust to the user's height, so to provide additional comfort in using the product. User will be able to target weeds thru the water clear capsule without bending over. The capsule is designed so that the user can easily see the weed target through the water clear plastic so that he knows when to spray over the weed making a direct contact.
The BOS “Stop Drift” Wand sprays herbicide (weed killer) onto specifically targeted weeds, while it will encapsulate or trap any chance of vapor/drift inside the capsule while the weed killer is dispersed on the target weed, while purposely preventing any chance of drift from reaching unwarranted objects outside the capsule.
The capsule has a dispensary type nozzle attached on the underneath side, and the wand, when attached to one capsule becomes the clear capsule, extendable wand, and nozzle assembly, designed to perform as described above.
The fluid is pressurized within the reservoir 115 and flows within the flexible hose 107, and the flow of the pressurized fluid is controlled by the trigger 105 of the handle device 103. The pressurized fluid flows through the central aperture 123 of the telescopic dispensing shaft 101, and flows into the cavity of the dome 109. The spray element 113 dispense is the fluid within the cavity of the dome 109.
While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular forms disclosed.
