Abstract
Abstract A spray guard adapted for use with a wand for spraying a liquid onto vegetation, the wand having a cylindrically shaped discharge tube and a nozzle tip attached to the end of the discharge tube. The spray guard includes a dome having an open end and provided with an aperture through which the discharge tube may selectively extend. The dome channels, directs, and forcuses the spray emitted from the nozzle tip toward a relatively localized area.

Total Claims: 19
Claim 1
Independent Claim
221 words
A spray guard adapted for use with a wand for spraying a liquid onto vegetation, the wand having a substantially cylindrically shaped discharge tube and a nozzle tip adapted to be selectively releasably attached to an end of the discharge tube such that the liquid may flow through the discharge tube, through the nozzle tip, and onto the vegetation, the nozzle tip having a width in a direction substantially orthogonal to the longitudinal axis of the discharge tube that is greater than the width of the discharge tube in a direction substantially orthogonal to the longitudinal axis of the discharge tube, said spray guard comprising: a dome having an open end and provided with an aperture, said dome being fashioned of a rigid, inflexible material surrounding the aperture such that the size of the aperture is constant, the width of the aperture being larger than the discharge tube width and smaller than the nozzle tip width whereby the dome may be mounted on the discharge tube only by disattaching the nozzle tip from the discharge tube, inserting and extending the discharge tube through the aperture, and reattaching the nozzle tip to the discharge tube while the discharge tube is extended through the aperture, and whereby the discharge tube may freely translate through the aperture after the nozzle tip has been reattached.

A spray guard adapted for use with a wand for spraying a liquid onto vegetation, the wand having a substantially cylindrically shaped discharge tube and a nozzle tip adapted to be selectively releasably attached to an end of the discharge tube such that the liquid may flow through the discharge tube, through the nozzle tip, and onto the vegetation, the nozzle tip having a width in a direction substantially orthogonal to the longitudinal axis of the discharge tube that is greater than the width of the discharge tube in a direction substantially orthogonal to the longitudinal axis of the discharge tube, said spray guard comprising: a dome having an open end and provided with an aperture, said dome being fashioned of a rigid, inflexible material surrounding the aperture such that the size of the aperture is constant, the width of the aperture being larger than the discharge tube width and smaller than the nozzle tip width whereby the dome may be mounted on the discharge tube only by disattaching the nozzle tip from the discharge tube, inserting and extending the discharge tube through the aperture, and reattaching the nozzle tip to the discharge tube while the discharge tube is extended through the aperture, and whereby the discharge tube may freely translate through the aperture after the nozzle tip has been reattached.
Claim 3
Dependent Claim
19 words
A spray guard according to claim 1 wherein said dome is substantially entirely fashioned of a rigid, inflexible material.
Claim 4
Dependent Claim
35 words
A spray guard according to claim 1 wherein said dome is fashioned substantially in the shape of a funnel having a first open end and a smaller second end in which the aperture is disposed.
Claim 5
Dependent Claim
51 words
A spray guard according to claim 2 wherein said dome is fashioned substantially in the shape of a truncated pyramid having a base end and a smaller upper end, the base end being the open end of said dome and the aperture being disposed in the upper end of said dome.
Claim 6
Dependent Claim
17 words
A spray guard according to claim 1 wherein said dome is fashioned substantially entirely of transparent plastic.
Claim 7
Dependent Claim
168 words
A spray guard adapted for use with a wand for spraying a liquid onto vegetation, the wand having a substantially cylindrical shaped discharge tube and a nozzle tip attached to an end of the discharge tube such that the liquid may flow through the discharge tube, through the nozzle tip, and onto the vegetation, said spray guard comprising: a dome having an open end and provided with an aperture, said dome being fashioned of a rigid, inflexible material surrounding the aperture such that the size of the aperture is constant, the size of the aperture being large enough to permit both the nozzle tip and the discharge tube to be inserted and extended therethrough; and means for selectively preventing the nozzle tip from being retracted back through the aperture after the nozzle tip has been inserted through the aperture and for permitting the discharge tube to freely translate through the aperture when the nozzle tip is prevented by said preventing means from being retracted back through the aperture.
Claim 8
Dependent Claim
168 words
A spray guard adapted for use with a wand for spraying a liquid onto vegetation, the wand having a substantially cylindrical shaped discharge tube and a nozzle tip attached to an end of the discharge tube such that the liquid may flow through the discharge tube, through the nozzle tip, and onto the vegetation, said spray guard comprising: a dome having an open end and provided with an aperture, said dome being fashioned of a rigid, inflexible material surrounding the aperture such that the size of the aperture is constant, the size of the aperture being large enough to permit both the nozzle tip and the discharge tube to be inserted and extended therethrough; and means for selectively preventing the nozzle tip from being retracted back through the aperture after the nozzle tip has been inserted through the aperture and for permitting the discharge tube to freely translate through the aperture when the nozzle tip is prevented by said preventing means from being retracted back through the aperture.
Claim 9
Dependent Claim
25 words
