A brush is injection molded in a multipart mold. The bristles of the brush are sequentially molded integrally with the base or handle. The bristles are extremely small and are injection molded in a unique molds. The bristle portion of the mold consists of a series a plates or semi-sphere cups, each of which is drilled with a diminutive drill bit. The plates and cups are then assembled so that the bores of the plates and cups are aligned to form the bristle containing portion of the mold. The mold portion for the bristles is injection molded with a first resin material. Then base or handle producing portion of the mold is injected with a second resin material. The selection of applicable resins, seize of bristles, spacing of bristles, viscosity of the to-be-dispensed fluid all considered in the defining of the amount of liquid to be carried and dispensed by the brush.

Method for injection molding a plastic monolith

A method for injection molding a plastic applicator with a ball of bristles produced integrally with a support handle. The mold consists of two opposing parts. The mold is machined by means of a laser. The mold is laser drilled with gradually decreasing depths of bores from the midpoint of the mold parts outwardly.

A liquid applicator includes an elongated hollowing body having opposed first and second open ends in fluid communication with one another, and a tip attached to the first open end and including a porous material. A closed, frangible ampule is supported within the second open end of the body and contains a liquid to be disposed.

Liquid applicator

The present invention pertains to two inserts to be used in conjunction with the nozzles of known liquid flow through applicators. The inserts have a proximate flange detailed to fit into a wider portion of the applicator and a bristle or dabber portion at its distal end detailed to extend beyond the applicator. The bristle or dabber portions are connected by an elongated rod portion. In one embodiment the rod portion is crisscrossed with a clockwise thread and a counter-clockwise thread whereby two disparate liquids may be mixed together through the flow transitory passage of the liquids in the nozzle. In the second embodiment the rod portion is essentially smooth. However, the external diameter of the rod is substantially less than the internal diameter of the passage of the applicator whereby an annular space is formed.

Fluid dropper with cap

A method for applying flock to the end of a tube which is to be used as a flow through applicator. An external end portion of the tube is coated with an adhesive, air is intermittently blown through the tube to keep the tube clear of unwanted adhesive. The end of the tube coated will the said uncured adhesive in then subjected to an application of flock under the aegis of electrostatic attraction while air is intermittently blow through the tube to thereby keep the tube essentially clear of flock. The tube carrying the flock is subjected to a heat cure. The tube may be of metal or a plastic. When the latter the end portion of the tube is subjected to a preliminary corona discharge whereby to active its service to increase the adhesive to the adhesive coating in a known manner.

Method and system for applying minute bristles to a flow through applicator

An applicator that has an elongated tubular handle with a proximate and a distal end. The distal end has a dauber of a foamed material which is coextensive with said handle and has a diameter the same as said tubular handle, the formed material is cylindrical thereby providing a recess which is preloaded with a to-be-dispensed liquid. The handle is provided with an annular ring. A cup with a mouth portion is mounted about the foamed material. The mouth portion is affixed to said outer circumference of said ring. The cup has an annular weakened score line whereby said cup may be broken away to expose said foamed material.

Applicator having a break away cup

A fluid applicator which is constructed of a relatively rigid plastic with a forwardly disposed distal end portion or nozzle which is constructed of a plastic material which is relatively more resilient. The applicator in some embodiments being adapted and constructed to be affixed to a syringe containing a to-be-distributed relatively high viscosity liquid or gel.

Fluid applicator

A fluid applicator system having a proximal end portion that has a male portion that can be connected to a female inner threaded hub that in turn is attached to a source of a fluid supply. The distal end terminates in a ball that is flocked with bristles that are adhered perpendicularly to the ball. The proximal end and the distal end is fluidly connected by a series of cylindrical tubes that are of decreasing outer diameter from the proximal end in the direction of the distal end.
