  • Patent number: 6685147
    Abstract: A holder for a nail polish bottle that allows the bottle to be tipped at any angle wanted by the user and that allows viewing of an applicator extracting polish from the bottle. It has a fixed post attached to a base that stabilizes the holder against unwanted motion during use. There is a pivoting post also. The top of the fixed post and the bottom of the pivoting post form a ball and socket joint that allows the pivoting post to tilt at any angle wanted by a user. The pivoting post is attached to a spring-loaded clip. The clip contains arms with non-slip inner surfaces. The arms have an arcuate hollow elliptical oval shape that allows the user to view the transferring of polish to the applicator so that a proper amount is transferred. The clip is opened by pressing its lever portions together to stress the spring. When the pressure on the lever portions ceases, the arcuate arms close to hold the bottle securely.
