Airtight container cover that is made by double injection molding method

Abstract

A thin packing cover needs some pressing and bending process to stick the packing material into the main cover. This inventory is the packing cover which can be manufactured without bending or pressing the main cover by the processing of double injection molding method that can inject the packing plastic material from upper and under packing place of the main cover.

What is claimed is:  
     
         1 . An airtight container cover that is made by double injection molding method wherein its improvement comprising, 
 a body is formed as one with the combining part, which is combined with the container by double injection molding method,    a coating layer is protruded toward the top through the hole or the opening part on the cover, so the airtight power is improved and the appearance is excellent as well as the coating layer that is formed inside of the combining part may not be separated.    
     
     
         2 . An airtight container cover that is made by double injection molding method as claimed in  claim 1  wherein, the opening part is formed instead of the said hole.  
     
     
         3 . An airtight container cover that is made by double injection molding method as claimed in  claim 1  wherein, the trademark of the product is printed on the surface of the protrusion that is protruded toward the top of the cover.  
     
     
         4 . An airtight container cover that is made by double injection molding method as claimed in  claim 1  wherein, the protrusion is made by double injection molding method with the hole in the inner wall of the combining part through the hole on the top of the cover.  
     
     
         5 . An airtight container cover that is made by double injection molding method as claimed in  claim 1  wherein, the protrusion is formed on the inner wall or outer wall of the combining part by double injection molding method and protruded through the hole on the top of the cover.
