Abstract: The present invention features a pen used, for example, to dispense nail polish for finger nail application. The design is for a unit of use, meaning that the preferred pen uses cartridges, i.e., units. In a preferred embodiment, each cartridge is filled with polish and has a brush head. After the cartridge is used, the user simply disposes of the old cartridge and replaces it with a new cartridge for the next application.

Abstract: A disposable container for application of paints, medicaments and coatings having a compressible hollow body with a closed end and a membrane sealed open end, and a stationary applicator housing fitted on the membrane sealed open end so that when the hollow body containing liquid is compressed, the membrane is punctured or fractured and the liquid is supplied to the applicator.

Abstract: This relates to a fingernail polish cartridge and dispenser. This will be provided as a sealed unit which may be readily placed in a reusable handpiece and wherein there is associated with a cartridge containing the polish a brush attachment and a plunger. When the brush attachment is moved into the cartridge by way of the handpiece, it will automatically open one end of the cartridge, that end being closed by a separately formed plug which has a sealed fit therein. Then a plunger is utilized to displace a removable panel at the opposite end of the cartidge followed by that removable panel seating on a piston and being moved into the cartridge by further movement of the plunger so as to force the liquid nail polish into the brush attachment.
