Claims18
A line marking applicator head comprising a holder specifically designed to non-releasably engage an aerosol dispenser, the aerosol dispenser comprising a container with a normally closed nozzle valve and including a propellant gas under pressure to discharge line marking fluid contained therein as a spray through the nozzle, a supporter to support the head in use to contact and readily move over a ground or surface upon which a line is to be sprayed, an actuator to operate the spray nozzle and means to define the width of the sprayed line;
- the line marking head and the aerosol dispenser together constituting a disposable line marking applicator.
In combination an aerosol dispenser comprising a container with a normally closed nozzle valve and including a propellant gas under pressure to discharge line marking fluid contained therein as a spray through the nozzle and a line marking head comprising a holder non-releasably engaged to the aerosol dispenser, a supporter to support the head in use to contact and readily move over aground or surface upon which a line is to be sprayed, an actuator to operate the spray nozzle and means to define the width of sprayed line;
- the line marking head and aerosol dispenser together constituting a disposable line marking applicator.
A disposable line marking applicator head adapted in use to receive an aerosol dispenser containing line marking fluid and a spray nozzle with a normally-closed valve, the head comprising:
- a. means for non-releasably engaging the aerosol dispenser;
- b. means, in use contacting and readily moving over a surface upon which a line is to be sprayed, for supporting the head;
- c. means for actuating in use the spray nozzle to spray a line;
- d. means for defining in use the width of the sprayed line.
