Container Insert for Zero Headspace

Abstract

A container suitable for containing a liquid composition and comprising an insert located in the neck of said container, and wherein when said container is filled with a liquid composition, zero headspace exists below said insert.

1 . A container suitable for containing a liquid composition and comprising an insert located in the neck of said container, and wherein when said container is filled with a liquid composition, zero headspace exists below said insert. 
   
   
       2 . An insert according to  claim 1 , wherein said insert is a valve. 
   
   
       3 . A container according to  claim 1 , wherein said container is a flexible container. 
   
   
       4 . A container according to  claim 3 , wherein said container is transparent or semi-transparent. 
   
   
       5 . A container according to  claim 1 , wherein said container comprises polyethylene, polypropylene, or poly(ethylene terephthalate). 
   
   
       6 . A liquid composition according to  claim 1 , wherein said liquid composition exhibits a pattern or design. 
   
   
       7 . A liquid composition according to  claim 5 , wherein said liquid composition is a multi-phase personal care composition. 
   
   
       8 . A method of achieving zero headspace according to the following steps:
 a. filling a container with a liquid composition to a level above the shoulders of said container;   b. inserting an into said container which displaces said liquid composition until the liquid composition flows through said valve due to a pressure differential;   c. allowing said valve to seal at substantial equilibrium.
