Patent ID: 7757906

Claim:
An air movement indicating device, comprising: an aerosol can including a dispensing mechanism for enabling pressurized dispensable contents contained within an interior space of the aerosol can to be selectively dispensed therefrom, wherein the pressurized dispensable contents includes a particulate-laden gas, and wherein said particulate is colored, and wherein said particulate includes electrically charged organic particulate held in suspension within the propellant such that said particulate is electrically charged as it passes through and is delivered from within the dispensing mechanism; a retention clip structure attached to an exterior portion of the aerosol can, wherein the retention clip structure includes a clip portion that is biased to a closed configuration for enabling the clip portion to securely engage a portion of an article for attaching the aerosol can to the article; and a cap assembly including a cap body attached to the aerosol can and a trigger moveably attached to the cap body, wherein the trigger includes a handle portion and a dispensing mechanism actuation portion attached to the handle portion, wherein the dispensing mechanism actuation portion of the trigger is located entirely within the interior space of the cap body, wherein the handle portion of the trigger is connected to the actuation portion of the trigger through an opening in the cap body such that a majority of the handle portion is located outside of the interior space of the cap body, wherein the dispensing mechanism actuation portion is located within an interior space of the cap body and is pivotably attached thereto in a manner allowing relative movement of the dispensing mechanism actuation portion with respect to the cap body and in a manner whereby movement of the dispensing mechanism actuation portion with respect to the dispensing mechanism is entirely independent of relative position of the cap body with respect to the aerosol can, wherein the dispensing mechanism actuation portion includes spaced apart arms each pivotably attached to the cap body at a first end portion thereof and fixedly attached to the handle portion at a second end portion thereof, wherein a nozzle of the dispensing mechanism extends between said arms, wherein a flow control portion of the dispensing mechanism is engaged with said spaced apart arms, wherein a centerline axis of the outlet portion of the nozzle is skewed with respect to a longitudinal axis of the aerosol can when the nozzle is in a non-dispensing position, and wherein the handle portion is movable from a rest position to a displaced position with respect to the cap body for causing said spaced apart arms of the dispensing mechanism actuation portion to act on the flow control portion of the dispensing mechanism such that said pressurized dispensable contents are dispensed from within the interior space of the aerosol can.
