Environment protected starch container device

Abstract

An environment protected starch container device includes a starch container mainly made of starch material for holding solid or liquid foods or other objects; a silicon layer adhered to a surface of the starch container; and wherein the function of the silicon layer is to cause the starch container to be waterproof; originally, the starch container is not waterproof; furthermore in natural environment, the silicon layer and the starch container are capably of decomposition naturally without polluting the environment; therefore the container is capable of holding water therein and is reusable for many times. The starch material comprises 50 wt %˜90 wt % (weight percentage) starch; 5 wt %˜25 wt % fiber enhancer for enhancing a structure of the starch material; and 3 wt %˜30 wt % CaCO3 for hardening the structure of the starch material. The starch material may further comprise 0.02 wt %˜5 wt % foaming material.

What is claimed is: 
     
         1 . An environment protected starch container device; comprising;
 a starch container mainly made of starch material for holding solid or liquid foods or other objects;   a silicon layer adhered to a surface of the starch container; and   wherein the function of the silicon layer is to cause the starch container to be waterproof; originally, the starch container is not waterproof; furthermore in natural environment, the silicon layer and the starch container are capably of decomposition naturally without polluting the environment; therefore the container is capable of holding water therein and is reusable for many times.   
     
     
         2 . The environment protected starch container device as claimed in  claim 1 , wherein the silicon layer is adhered to an inner surface of the starch container. 
     
     
         3 . The environment protected starch container device as claimed in  claim 1 , wherein the silicon layer is adhered to a whole surface of the starch container. 
     
     
         4 . The environment protected starch container device as claimed in  claim 1 , wherein the starch container is a cup and at least one inner side thereof is coated with the silicon layer. 
     
     
         5 . The environment protected starch container device as claimed in  claim 1 , wherein the starch container is a food disk and at least one inner side thereof is coated with the silicon layer. 
     
     
         6 . The environment protected starch container device as claimed in  claim 1 , wherein the starch container is a bowl and at least one inner side thereof is coated with the silicon layer. 
     
     
         7 . The environment protected starch container device as claimed in  claim 1 , wherein the starch container is a box. 
     
     
         8 . The environment protected starch container device as claimed in  claim 1 , wherein the starch material comprises
 50 wt %˜90 wt % (weight percentage) starch;   5 wt %˜25 wt % fiber enhancer for enhancing a structure of the starch material; and   3 wt %˜30 wt % CaCO3 for hardening the structure of the starch material.   
     
     
         9 . The environment protected starch container device as claimed in  claim 9  wherein the fiber enhancer is selected from plant fibers and pulp fibers. 
     
     
         10 . The environment protected starch container device as claimed in  claim 9 , wherein the starch material further comprises 0.02 wt %˜5 wt % foaming material. 
     
     
         11 . The environment protected starch container device as claimed in  claim 11 , wherein the foaming material is selected from yeast and generally used chemical foaming material; and after forming, 40%˜60% of the volume of the porous starch container is hollowed. 
     
     
         12 . The environment protected starch container device as claimed in  claim 9 , wherein starch of the starch material is selected from potato starch, corn starch, wood starch, and other plant starch.
