## Abstract

A hand-held spray paint marking tool includes a lower chamber for holding at least one can of spray paint in an inverted position. The chamber extends upward and terminates in a handle grip that includes an activation mechanism. A stencil including the desired marking pattern is attached to the underside of the lower chamber. When the activation mechanism is depressed by the user, the spray paint cans are activated such that the paint passes through the stencil and marks the ground underneath.

## Claims

### Claim 1

A spray paint marking tool comprising
a lower chamber comprising a plurality of openings for holding a plurality of spray paint containers in an inverted position;
a tool handle grip allowing for said tool to be held in one hand, the tool handle grip including an activation trigger;
an extension arm connected at one end to the lower chamber and an opposite end to said tool handle grip, said extension arm including a single activation mechanism coupled between said activation trigger and said lower chamber so as to cause the simultaneous release of paint from the plurality of spray paint containers upon release of said activation trigger; and
a marking stencil attached to said lower chamber and disposed such that released paint will pass through said marking stencil and mark an area underneath said marking tool.

### Claim 2 (depends on 1)

A spray paint marking tool as defined in claim 1 wherein the lower chamber further comprises a channel region for holding the marking stencil.
