Abstract: A micro-applicator includes a body and a tip holder located at an end of the body. A spring-loaded plunger extends through the body such that when sufficient force is applied to the end of the plunger extending out of the body, the plunger extends into the tip holder to eject a tip held therein. Another micro-applicator includes a grip, a tip holder located at an end of the grip and a spring-biased ejector configured such that compression of the spring causes the ejector to extend through tip holder and eject a tip held therein. Another micro-applicator includes a body, including a grip portion and a tip holding portion. The tip holding portion is configured to hold a disposable dental tip. A spring-biased ejector located within the body allows quick and efficient ejection of the disposable dental tip.

Abstract: 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.

Abstract: A dental cartridge for dispensing a dental material having a body portion made of a material transparent to at least a portion of the visible light spectrum and opaque to the actinic light of the dental material contained therein. The dental cartridge is supplied with a to-be driven piston which is constructed of two affixed parts in tandem, a forward portion and a rearward portion. The forward portion is more resilient than the rearward portion. The rearward portion is affixed to the forward portion by a peg system that fits into the forward portion.

Abstract: The present invention provides a method to rapidly provide genotype screening of a plurality of biological samples disposed on an adsorbent carrier in a designated well of a microwell container for remote user by a screening laboratory. Additionally, this invention relates to a genotyping kit including at least one swab holder, at least one swab and a microwell container.

Abstract: 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.

Abstract: 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.

Abstract: A hand held vibrating instrument in the shape of a conventional pen or pencil writing instrument. The tip of this instrument is to be operationally connected to a tool such as a resilient rod. The instrument is connected to a source of electric power which operates an electric motor. An eccentric weight is secured to a drive shaft of the motor to thereby impart rapid vibrations to the tip of the instrument.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A dispenser for elongated rod-like articles. The dispenser has a housing which has a trap chamber rotatable cylinder wherein the trap gravitationally captures from the bottom of a pile, one at a time, one of the rod-like articles and arcuately moves it by means of the cylinder to a downwardly facing position from whence the rod-like article falls onto a chute. The housing is loaded from a cartridge which contains the rod-like articles and is inserted on top of the housing when in use. The cylinder is constructed of a plurality of spaced apart discs each of which has a radially extending notch in alignment with one another to thereby define an elongated trap for the rod-like articles to be dispensed.
