Abstract
Abstract Finger print dispensing apparatus includes a compact manually operated portable unit. The unit includes a detachable brush for spreading the powder dispensed, a squeezable detachable container for holding the powder and a nozzle arrangement for delivering the powder to the brush when the container is squeezed. An extendible and retractable sleeve is provided to either house and shape the brush during non use or to expose the brush during use. Moisture proof means are provided on the sleeve to house the brush and keep the powder in the container dry when the apparatus is not in use.
