Cosmetic container

Abstract

A cosmetic container comprises an outer shell comprising a concave inner surface that defines an inner space. An inner shell comprises a top and a bottom, where the bottom is at least partially located within the inner space of the outer shell. One or more engagement features are positioned proximate the top of the inner shell. A liquid-tight chamber is defined between the outer shell and the inner shell and contains a material with a refractive index greater than 1.0.

1 . A cosmetic container comprising:
 an outer shell comprising a concave inner surface defining an inner space;   an inner shell comprising a top and a bottom, the bottom being at least partially located within the inner space of the outer shell, and one or more engagement features disposed proximate the top;   a liquid-tight chamber defined between the outer shell and the inner shell; and   a material with a refractive index greater than 1.0 located within the liquid-tight chamber.   
     
     
         2 . The cosmetic container of  claim 1  further comprising a lid having an outer annular surface and an inner annular surface, wherein the inner annular surface comprises one or more complimentary engagement features configured to interact with the one or more engagement features of the inner shell. 
     
     
         3 . The cosmetic container of  claim 1 , wherein the material is a salt solution. 
     
     
         4 . The cosmetic container of  claim 3 , wherein the salt solution comprises sodium chloride dissolved in water. 
     
     
         5 . The cosmetic container of  claim 3 , wherein the refractive index of the salt solution is about 1.33. 
     
     
         6 . The cosmetic container of  claim 1 , wherein the outer shell further comprises a bottom surface having at least one indentation or depression that extends into the liquid-tight chamber. 
     
     
         7 . The cosmetic container of  claim 1 , wherein the outer shell further comprises a shoulder configured to engage a portion of the inner shell. 
     
     
         8 . The cosmetic container of  claim 2 , wherein the lid further comprises one or more surface features configured to assist in coupling and decoupling the lid to the inner shell. 
     
     
         9 . The cosmetic container of  claim 1 , wherein the material is renewable and biodegradable. 
     
     
         10 . A container comprising:
 an outer shell comprising a top and a bottom, the outer shell comprising an inner surface defining an interior space;   an inner shell comprising a top and a bottom and is coupled to the outer shell, wherein the inner shell is at least partially located within the interior space of the outer shell;   a liquid-tight chamber defined between the outer shell and the inner shell; and   a material with a refractive index greater than 1.0 located within the liquid-tight chamber.   
     
     
         11 . The container of  claim 10 , further comprising a lid having an outer annular surface and an inner annular surface, wherein the inner annular surface is configured to removeably couple with a portion of the inner shell. 
     
     
         12 . The container of  claim 10 , wherein the inner shell further comprises one or more engagement features disposed proximate the top. 
     
     
         13 . The container of  claim 11 , wherein the inner annular surface of the lid comprises one or more complimentary engagement features configured to interact with the one or more engagement features of the inner shell. 
     
     
         14 . The container of  claim 10 , wherein the material is a salt solution. 
     
     
         15 . The container of  claim 14 , wherein the refractive index of the salt solution is about 1.33. 
     
     
         16 . The container of  claim 10 , wherein the outer shell further comprises a shoulder configured to engage a portion of the inner shell. 
     
     
         17 . The container of  claim 11 , wherein the lid further comprises one or more surface features configured to assist in coupling and decoupling the lid to the inner shell. 
     
     
         18 . The container of  claim 10 , wherein the material is renewable and biodegradable.
