ABSTRACT:
BACKGROUND OF THE INVENTION
Increasingly there is a need for tiny fluid applicators to distribute relatively small quantities of a fluid from a source to the site where it is needed.
Such small applicators have found ready acceptance in dentistry where small quantities of liquid medicament must be applied to the interstices of teeth. Such small applicators are also used by hobbyists to supply a liquid adhesive to parts that are assembled. Such small applicators are useful in applying small quantities of fluid lubricants to watch parts in the horology industry or small mechanical movements in the auto industry. The fluid applicators are also used for cosmetic purposes.
In all of such uses a small fluid containing source or reservoir is fluidly and operatively aligned with a small applicator usually of the disposable kind.
SUMMARY OF THE INVENTION
The invention is concerned with a fluid applicator system having a proximal end portion that has a threaded male portion that can be fluidly connected to a female inner threaded hub that in turn is attached to a source of a fluid. The distal end terminates in a ball that has a conduit therethrough. The ball is flocked with bristles that are adhered perpendicularly to the surface of the ball. The proximal end and the distal end is fluidly connected by a series of cylindrical tubes that are stepped with decreasing outer diameter from the proximal end in the direction of the distal end.
