Egg Package Assembly

Abstract

An egg package assembly includes a protective case that contains predetermined number of eggs and a sleeve that fixedly surrounds the protective case. The protective case comprises a base and a lid. The sleeve comprises a thin packing film that is shrunk by heat. The sleeve is provided having a length similar to that of the case and a width wider than that of the case. After heat shrinking, the sleeve conforms to the shape of the case and fixed to the case. The length of the sleeve shrinks and allows the ends of the case to be exposed.

1 . An egg package assembly comprising:
 a) a protective case that is adapted to contain predetermined number of eggs; and   b) a sleeve that fixedly surrounds the protective case;   
       wherein the protective case comprises a base and a lid, wherein the sleeve comprises a thin packing film. 
     
     
         2 . The egg package assembly of  claim 1 , wherein the predetermined number is 6, 12, 18 or 24. 
     
     
         3 . The egg package assembly of  claim 1 , wherein the base and lid of the protective case comprise projections that are adapted to separate eggs. 
     
     
         4 . The egg package assembly of  claim 1 , wherein the base and lid of the protective case are made of molded fiberboard or various plastics. 
     
     
         5 . The egg package assembly of  claim 1 , wherein the sleeve comprises a heat shrink film. 
     
     
         6 . The egg package assembly of  claim 5 , wherein the heat shrink film is made of PVC, PET, PLA or OPS. 
     
     
         7 . The egg package assembly of  claim 5 , wherein the heat shrink film has a thickness in a range from about 45μ to about 60μ. 
     
     
         8 . The egg package assembly of  claim 5 , wherein the heat shrink film comprises has a shape of a tube before it is shrunk, wherein the length of the tube is about the length of the protective case and the width of the tube is about 8 mm to about 14 mm greater than the width of the protective case. 
     
     
         9 . The egg package assembly of  claim 5 , wherein the heat shrink film is shrunk by heating at temperature from about 65 Celsius to about 90 degree Celsius for about 4 to about 5 seconds. 
     
     
         10 . The egg package assembly of  claim 9 , wherein the heat shrink film shrinks about 30 to 40% in width and no greater than about 6% in length.
