Resealable plastic sealing container

Abstract

A resealable plastic sealing container is constructed to include a container body, the container body having a coupling flange of substantially Π-shaped cross-section extended around a top opening thereof, and a cover adapted to seal the top opening of the container body, the cover having a peripheral coupling flange of substantially Π-shaped cross-section for press-mounting onto the coupling flange of the container body, and a layer of non-toxic glue covered on the inner surface of the coupling flange and adapted to seal the coupling flange of the cover to the coupling flange of the container body.

What the invention claimed is:  
     
         1 . A resealable plastic sealing container comprising a container body having a top opening, and a cover adapted to seal the top opening of said container body, wherein said container body has a coupling flange of substantially Π-shaped cross-section extended around said top opening thereof; said cover has a peripheral coupling flange for press-mounting onto the coupling flange of said container body, the coupling flange of said cover has a substantially Π-shaped cross-section, the Π-shaped cross-section of the coupling flange of said cover having an inner surface, and a layer of non-toxic glue covered on the inner surface of said coupling flange and adapted to seal the coupling flange of said cover to the coupling flange of said container body.  
     
     
         2 . The resealable plastic sealing container as claimed in  claim 1 , wherein said non-toxic glue is applied to a horizontal middle part of the inner surface of the Π-shaped cross-section of the coupling flange of said cover.  
     
     
         3 . The resealable plastic sealing container as claimed in  claim 1 , wherein said non-toxic glue is applied to a horizontal middle part and two opposite vertical side parts of the inner surface of the Π-shaped cross-section of the coupling flange of said cover.  
     
     
         4 . The resealable plastic sealing container as claimed in  claim 2 , wherein said cover and said container are vacuum-molded from plastics.  
     
     
         5 . The resealable plastic sealing container as claimed in  claim 3 , wherein said cover and said container are vacuum-molded from plastics.  
     
     
         6 . The resealable plastic sealing container as claimed in  claim 4 , wherein the thickness of said layer of non-toxic glue is about 0.02 mm˜0.07 mm.  
     
     
         7 . The resealable plastic sealing container as claimed in  claim 5 , wherein the thickness of said layer of non-toxic glue is about 0.02 mm˜0.07 mm.
