Definitions

  • the field of the invention is applicators for nail polish, paints, glues and lubricants.
  • pen dispensers A requisite for pen dispensers, particularly those produced en masse, is that they are simple and economical to manufacture. Therefore, pen dispensers should have as few component parts as possible which are easy to assemble at high speed, either by hand or by automated assembly machines.
  • pen manufacturers Another feature desirable to pen manufacturers is that the parts of their pens which users can disassemble, discard and replace—such as cartridges—exclusively operate with other parts of their own pens. Thus, pen manufacturers would prefer that their brand of cartridges only work with the same brand of pen dispensers. In this way, users who wish to replace a cartridge must buy one of the same brand, or replace the entire pen.
  • the ratchet wheel comprises a button with a spring, a top flat ratchet and a bi-directional ratchet wheel with two sets of teeth running in opposite directions.
  • the rod ratchet When the rod ratchet is "activated,” it engages with the ratchet wheel and bottom ratchet and can be advanced by pressing down on the flow control button which in turn presses down on the top ratchet, thereby advancing the wheel and rod ratchet one notch in the same direction.
  • the ratchet wheel is made up of several different components.
  • the present invention features a pen applicator used, for example, to dispense materials such as nail polish, paints, glues and lubricants.
  • the design is for a unit of use, meaning that the preferred pen applicator uses cartridges, i.e., units.
  • the cartridge comprises a disposable capsule filled with the substance to be dispensed and a brush housing unit that holds the capsule in place.
  • the pen applicator includes a pen dispenser having a rotating sleeve for accepting the cartridge.
  • the rotating sleeve and cartridge have corresponding shapes so that one can interlock with another.
  • the cartridge and rotating sleeve have corresponding screw thread shapes.
  • the user inserts and interlocks, preferably by screwing, a cartridge into a pen dispenser having the corresponding shape.
  • the user simply unscrews and disposes of the old cartridge and substitutes it with a new cartridge having the same shape for the next application.
  • Each brand of pen applicator could adopt its own particular shape for the cartridge and rotating sleeve to insure that one component cannot be used with another component of a different brand.
  • Also featured are methods of making the pen applicators, dispensers and cartridges described herein. The components are combined to form the applicator, dispenser and cartridge and then used to apply the substance being dispensed, for example nail polish. Examples of preferred embodiments of each of the components are summarized herein.
  • the pen dispenser is the device that dispenses the nail polish or other substances from the cartridge system.
  • the pen dispenser includes a rotating sleeve that accepts the cartridge.
  • the interior surface of the rotating sleeve has a particular shape that corresponds to the shape of the inserted cartridge.
  • the pen preferably uses a ratchet system that advances the rod ratchet a measured amount each time the flow control button is depressed. Depressing the button advances the rod ratchet a measured amount, and then the button returns to its original position by use of a coil spring.
  • the cartridge To disengage the cartridge, it is rotated counter clockwise and the rotating sleeve within the pen also is rotated to expose the flat sides of the rod ratchet which then releases the rod ratchet to its original position by use of a coil spring. The pen is then ready for use with another cartridge having the same shape as the disposed cartridge.
  • Ratchet Systems There are at least two alternative ratchet systems. Both systems employ a spring loaded rod ratchet, a top ratchet and a bottom ratchet, wherein the rod ratchet engages both the top ratchet and the bottom ratchet.
  • the top ratchet comprises a bi-directional ratchet wheel, a spring loaded top flat ratchet and a button spring.
  • the top ratchet comprises a single-piece leaf spring that operates as both a ratchet and a spring. Preferably this leaf spring is generally v- shaped.
  • the bottom ratchet comprises a ratchet and spring or, alternatively, a single-piece leaf spring that also operates as a ratchet and spring.
  • the bottom leaf spring is preferably generally u-shaped.
  • the leaf springs of the top and bottom ratchet are preferably metal pieces produced by a four slide machine.
  • the pen dispenser also includes a protective outer shell that comprises two half jackets. These half jackets may snap fit together at the rear of the pen dispenser and secured together at the front of the pen dispenser by an outer decorative ring. Alternatively, these half jackets may be molded together during construction.
  • the capsule preferably is a tube open at both ends.
  • the ends have a step on each side that can be folded over to seal the ends with a Cap.
  • the tube can be metal, plastic or other material.
  • the capsule preferably is closed at one end and open at the other end. At the closed end there is a coined area in the center that is thinner than the rest of the capsule body. This allows the spike to penetrate the capsule and allow the substance to flow through the spike and into the brush or other applicator.
  • the capsule is filled with the substance to be dispensed and the piston is then inserted into the capsule. The piston prevents the substance from flowing out of the capsule when it is penetrated by the rod ratchet.
  • the open end has a step to allow the cap to seat on the step and have the ends folded over onto the cap creating the seal.
  • the capsule is then penetrated by the rod ratchet from the pen dispenser and it pushes forward the piston which in turn pushes the entire capsule forward in the brush housing causing it to be penetrated by the spike in the coined area of the capsule.
  • the rod ratchet moves forward it will dispense a measured amount of the substance into the spike and into the brush or other applicator.
  • Cap preferably is a circular piece of metal, plastic or other material that is used to seal the capsule. In the first capsule design two caps are needed, one for each end. In the second capsule design only one cap is needed to seal the open end of the capsule. Spike
  • the spike preferably is identical on both ends. There is a hole that runs through the center of the spike. Both ends have a very sharp tip that is used to penetrate the capsule. Once the capsule is penetrated the substance to be dispensed flows through the hole in the center of the spike. At the other end of the spike the substance flows into either a brush fiber or other type of applicator which can be a foam tip, sponge or nothing at all. The spike is held in the brush housing using a tension fit between the spike, brush housing and fiber.
  • Piston can be made of plastic, metal or other material. It is inserted into the capsule after the substance to be dispensed is filled in the capsule. The hollow end is inserted first. The purpose of the piston is to prevent the flow of the substance to be dispensed from leaking back out behind the piston and into the pen dispenser once the seal has been penetrated.
  • the brush housing holds the capsule in place before it is ready to be dispensed.
  • a portion of the brush housing contacts the inner surface of the rotating sleeve. This portion of the brush housing is shaped to correspond to the shape of the interior surface of the rotating sleeve, thereby allowing the cartridge and pen dispenser of the same brand to interlock.
  • FIG. 2 shows various detailed views of preferred components of the invention.
  • Figure 3 shows a blown-up view of the embodiment of the pen dispenser seen in Figure 1 featuring a ratchet wheel.
  • Figure 4 shows a blown-up view of an alternative embodiment of the pen dispenser featuring a top leaf spring and bottom leaf spring.
  • Figure 5 shows an exploded view of the top leaf spring and flow control button into which it is secured.
  • Figure 6 shows cross-sectional views of the rotating sleeve and cartridge with screw thread shapes.
  • the pen dispenser and cartridge system work in the following manner.
  • the user inserts a cartridge into the rotating sleeve of the pen dispenser.
  • the brush housing and interior surface of the rotating sleeve have corresponding shapes so that the cartridge is easily inserted into and interlocks with the rotating sleeve. If the shapes of the brush housing and interior surface do not correspond, the user cannot screw the cartridge into the rotating sleeve.
  • a spring loaded rod ratchet is in a fully retracted position in the pen dispenser and is not engaged either to the ratchet wheel or bottom ratchet. As the user screws the cartridge into the pen dispenser using a clockwise rotation, the cartridge continues to turn until it becomes snug. At this point the user continues to rotate the cartridge assembly another 90 degrees.
  • the button is attached to spring loaded top ratchet that in turn engages a bi-directional ratchet wheel.
  • the depression of the button presses down on the spring loaded top ratchet which in turn advances the bi- directional ratchet wheel a single notch.
  • the bi-directional ratchet wheel is designed with two sets of teeth, the inside set runs one direction while the outside set runs in the opposite direction. This system allows the top ratchet to advance the ratchet wheel and rod ratchet in the same direction.
  • the button is attached to a generally v- shaped, metal leaf spring comprised of two leaves.
  • the button includes a slotted cavity into which the one leaf is secured.
  • the other leaf extends between two ratcheting teeth on the rod ratchet.
  • the button in this embodiment presses down on one leaf, which in turn forces the second leaf to push forward the immediately preceding ratcheting tooth and thereby advance the rod ratchet.
  • the bottom ratchet is a generally u-shaped metal leaf spring. One end of this leaf spring pushes against a tooth to stabilize the rod ratchet and prevent it from retracting while the top ratchet pushes it forward to dispense substance within the cartridge.
  • the rod ratchet As the rod ratchet advances, it breaks through the thin rear membrane of the capsule after which it contacts the piston. At the same time, the forward motion of the rod ratchet against the rear of the capsule forces the forward membrane to be penetrated by the spike creating an exit point for the nail polish on to the brush. Once contact is made with the piston it begins to move forward pushing the nail polish out of the capsule through the small exit hole created by the spike. Finally the rod ratchet continues to move forward as the user pushes down the flow control button and forces all of the nail polish out of the capsule and on to the brush for application. After the nail polish application is completed the user simply turns the used cartridge counter clockwise.
