Abstract

A method for decorating a glass or plastic transparent or translucent bottle, for the cosmetic field, for containing a cosmetic product such as a perfume, or the like, the decoration of which is carried out inside the bottle, and which consists in making at least one coating onto the inner surface of the bottle, by spraying a liquid mist inside the bottle, characterised in that the liquid is chemically inert with a characteristic close to glass so that the inner coating forms a barrier protecting layer for protecting the cosmetic product from any possible migration detrimental to the fragrance and/or colour as wells as the preservation thereof.

1 . A bottle, for cosmetic products, decorated from the inside by a method for decorating a glass or plastic transparent or translucent bottle, for the cosmetic field, for containing a cosmetic product, a decoration of which is made inside the bottle, and which method comprises:
 applying at least one coating on an inner surface of the bottle by spraying a liquid inside the bottle,   wherein the sprayed liquid is a silica-based polymer, said liquid being chemically inert so that the coating forms a barrier layer protecting the cosmetic product from any migration detrimental to quality of the fragrance and/or colour thereof as well as preserving the cosmetic product,   wherein the bottle is transparent or translucent, of glass or plastics.   
     
     
         2 . The bottle according to  claim 1 , wherein the inner coating contacting the cosmetic product is chemically inert with a characteristic close to glass. 
     
     
         3 . The bottle according to  claim 1 , wherein the coating is silica based. 
     
     
         4 . The bottle according to  claim 3 , wherein the silica-based coating includes colour pigments. 
     
     
         5 . The bottle according to  claim 4 , wherein the pigments added to the silica matrix are inorganic or organic pigments. 
     
     
         6 . The bottle according to  claim 5 , wherein the pigments are metal oxides. 
     
     
         7 . The bottle according to  1 , wherein the inner wall of the bottle includes at least a decorating layer beneath the inert layer of inner coating.
