Liquid filled container and method of manufacture

Abstract

A general object of the present invention is to provide a liquid filled container constructed from a small tube of glass welded inside a larger tube of glass that has been blown or molded to a desired shape or size. The liquid filled bottle comprises an outer tube that has been blown or molded into a decorative shape, an inner tube welded to the outer tube, at least one support post for anchoring the inner tube and the outer tube, a female stone ground fitting that is welded to the opening of the bottle, and a stone ground male bottle stopper. The outer tube and inner tube forming a cavity to house a liquid that is sealed within the cavity. Preferably the liquid fill is an alcohol or glycerin based liquid with a freezing temperature that is lower than water. Additionally, the liquid fill may also glow in the dark or contain decorative agents such as glitter.

1 . A method for manufacturing a container comprising:
 shaping an outer tube into a desired shape;   forming a small hole at the bottom portion of the outer tube;   preparing an inner tube for insertion into the outer tube by closing an end of the inner tube and welding at least one support post to the surface of the outer tube;   inserting the inner tube into the outer tube and heating a portion of the outer tube adjacent to the at least one support post so that the outer tube is welded to the support post;   forming the base of the container by cutting and closing the bottom section of the outer tube; and   forming the top of the container by cutting and working the top end of the inner tube to create a container opening.   
     
     
         2 . The method according to  claim 1 , wherein shaping the outer bottle comprises:
 closing the outer tube;   heating a portion of the closed outer tube and blowing a bubble shape.   
     
     
         3 . The method according to  claim 1 , wherein the desired shape is two circular bulbs. 
     
     
         4 . The method according to  claim 1 , wherein the desired shape is a cylinder. 
     
     
         5 . The method according to  claim 1 , wherein the desired shape is a cone. 
     
     
         6 . The method according to  claim 1 , wherein the desired shape is a sphere. 
     
     
         7 . The method according to  claim 1 , wherein there are three support posts. 
     
     
         8 . The method according to  claim 7 , wherein two of the support posts are located on a side of the inner tube and one support post is located at the closed bottom end of the inner tube. 
     
     
         9 . A container comprising:
 an inner tube;   an larger outer tube;   at least one support post connecting the inner tube to the outer tube;   the inner tube and outer tube joined at the top and forming an opening for the container.   
     
     
         10 . The container of  claim 9  further comprising an opening for filling the cavity formed between the inner wall of the outer tube and the outer wall of the inner tube. 
     
     
         11 . The container of  claim 9  wherein the support post connects the bottom of the inner tube to the bottom of the outer tube. 
     
     
         12 . The container of  claim 9  wherein there are three support posts. 
     
     
         13 . The container of  claim 9  wherein the outer tube is a cylinder. 
     
     
         14 . The container of  claim 9  wherein the outer tube is has a cross section shape of two circular bulbs. 
     
     
         15 . The container of  claim 9  wherein the outer tube is a cone. 
     
     
         16 . The container of  claim 9  wherein the outer tube is a sphere. 
     
     
         17 . The container of  claim 9  wherein the inner tube and outer tube share the same shape. 
     
     
         18 . The container of  claim 9  wherein the inner tube and outer tube are not the same shape.
