Device for applying and removing nail polish

Abstract

A device for applying or removing nail polish or nail art has a replaceable cartridge with a distal end removably coupleable to a proximal end of a handle. The cartridge has a reservoir that contains a liquid, such as nail polish or nail polish remover and a flow control member (e.g., valve) actuatable to allow flow of the liquid out of the distal end of the cartridge. The handle has a flow path therethrough that extends between its proximal end to an applicator implement (e.g., brush, sponge) attached to its distal end, the flow path in fluid communication with the flow control member when the cartridge is coupled to the handle. Selective actuation of the flow control member by the user (e.g., by squeezing the cartridge) allows fluid to flow out the reservoir and through the flow path in the handle to the applicator implement for application of the fluid by the user to a finger or toe nail.

What is claimed is: 
     
         1 - 19 . (canceled) 
     
     
         20 . A device for applying or removing nail polish or nail art on a finger or toe nail, comprising:
 a first portion comprising a chamber; and   a second portion comprising a handle at a proximal end and an applicator head at a distal end, the second portion being a single piece;   wherein the handle and the chamber form a continuous contoured top surface comprising a concave surface extending from a proximal end of the chamber to the distal end of the handle, the concave surface configured to receive a user’s finger thereon,   wherein the handle and the chamber form a continuous contoured bottom surface comprising a convex surface extending from a proximal end of the chamber to a distal end of the handle, the convex surface configured to receive one or more user’s fingers thereon,   wherein the continuous contoured top surface and the continuous contoured bottom surface have a circular profile when viewed in top plan view.   
     
     
         21 . The device of  claim 20 , wherein the chamber has a maximum width that is greater than a maximum width of the applicator head. 
     
     
         22 . The device of  claim 21 , wherein the chamber is configured to receive a volume of liquid chosen from a group consisting of nail polish or nail polish remover, wherein selective actuation of the chamber by a user allows the liquid to flow out from the chamber and to a flow path of the applicator head for application of the liquid by the user to the finger or toe nail. 
     
     
         23 . The device of  claim 22 , further comprising a valve that selectively allows flow of the liquid from the chamber. 
     
     
         24 . The device of  claim 22 , wherein selective actuation of the chamber comprises squeezing of the chamber. 
     
     
         25 . A device for applying or removing nail polish or nail art on a finger or toe nail, comprising:
 a handle;   a chamber coupled to the handle; and   wherein a distal end of the handle is configured to removably couple to an applicator head,   wherein the handle and the chamber form a continuous contoured top surface extending from a proximal end of the chamber to the distal end of the handle,   wherein the handle and the chamber form a continuous contoured bottom surface extending from the proximal end of the chamber to the distal end of the handle.   
     
     
         26 . The device of  claim 25 , wherein the continuous contoured top surface and the continuous contoured bottom surface have a circular profile when viewed in top plan view. 
     
     
         27 . The device of  claim 25 , wherein the continuous contoured bottom surface comprises a convex surface, the convex surface configured to receive one or more user’s fingers thereon. 
     
     
         28 . The device of  claim 25 , wherein the continuous contoured top surface comprises a concave surface, the concave surface configured to receive a user’s finger thereon. 
     
     
         29 . The device of  claim 25 , wherein the distal end of the handle is configured to removably couple to the applicator head via a press-fit connection. 
     
     
         30 . The device of  claim 25 , wherein the distal end of the handle is configured to removably couple to the applicator head via a key-slot connection. 
     
     
         31 . The device of  claim 25 , wherein the distal end of the handle is configured to removably couple to the applicator head via a snap-fit connection. 
     
     
         32 . The device of  claim 25 , wherein the distal end of the handle comprises a ridge or a protrusion that snaps onto a groove or a recess of the applicator head. 
     
     
         33 . The device of  claim 25 , wherein the chamber has a maximum width that is greater than a maximum width of the applicator head. 
     
     
         34 . A kit for applying or removing nail polish or nail art on a finger or toe nail, comprising:
 a first portion comprising a chamber,   a second portion comprising a handle at a proximal end of the second portion;   wherein a distal end of the handle is configured to removably couple to an applicator head,   wherein the first portion and the second portion form a continuous contoured top surface extending from a proximal end of the first portion to the distal end of the second portion,   wherein the first portion and the second portion form a continuous contoured bottom surface extending from a proximal end of the first portion to a distal end of the second portion,   one or more applicator implements, each applicator implement operatively coupleable to the distal end of the handle.   
     
     
         35 . The kit of  claim 34 , wherein the continuous contoured top surface and the continuous contoured bottom surface have a circular profile when viewed in top plan view. 
     
     
         36 . The kit of  claim 34 , wherein the one or more applicator implements are chosen from a group consisting of a brush, a sponge, a pen tip, a stamper tip, a striper tip, and a blotter tip. 
     
     
         37 . The kit of  claim 34 , wherein the chamber has a maximum width that is greater than a maximum width of the applicator head. 
     
     
         38 . The kit of  claim 34 , wherein the continuous contoured bottom surface comprises a convex surface, the convex surface configured to receive one or more user’s fingers, wherein the continuous contoured top surface comprises a concave surface, the concave surface configured to receive a user’s finger thereon.
