Food storage container

Abstract

Disclosed is a food storage container including a container body including a bottom part and a lateral part to form an interior space, a bottom film attached to the bottom part, and a lateral film forming a first overlapping part where the lateral film overlaps with the bottom film and a second overlapping part where an end portion overlaps with another end portion, and being attached to the lateral part. The food storage container has an improved film structure as compared with a conventional complicated film structure and has a high oxygen barrier performance.

1 . A food storage container comprising:
 a container body including a bottom part and a lateral part to form an interior space;   a bottom film attached to the bottom part; and   a lateral film forming a first overlapping part where the lateral film overlaps with the bottom film and a second overlapping part where an end portion overlaps with another end portion, and being attached to the lateral part.   
     
     
         2 . The food storage container of  claim 1 , wherein the container body is integrated with the respective films by insert molding. 
     
     
         3 . The food storage container of  claim 1 , wherein the bottom film and the lateral film each comprise:
 a lower layer formed of polypropylene (PP);   at least one oxygen barrier resin layer disposed on the lower layer; and   an upper layer disposed on the oxygen barrier resin layer and formed of PP.   
     
     
         4 . The food storage container of  claim 3 , wherein the oxygen barrier resin layer comprises polyethylene terephthalate (PET). 
     
     
         5 . The food storage container of  claim 3  or  4 , wherein the bottom film and the lateral film each further comprise an ivory white layer disposed between the lower layer and the oxygen barrier resin layer and formed of ivory white PP or ivory white PET. 
     
     
         6 . The food storage container of  claim 1 , wherein the container body further comprises a flange extending outwards from an upper portion of the lateral part, the lateral film is attached to an upper surface of the flange as well as to the lateral part, and the food storage container further comprises a lead film attached to the lateral film on the upper surface of the flange. 
     
     
         7 . The food storage container of  claim 6 , wherein the lead film comprises:
 a lower layer formed of PP;   at least one oxygen barrier resin layer disposed on the lower layer; and   an upper layer disposed on the oxygen barrier resin layer and formed of PP.   
     
     
         8 . The food storage container of  claim 7 , wherein the oxygen barrier resin layer comprises PET. 
     
     
         9 . The food storage container of  claim 4  or  8 , wherein the oxygen barrier resin layer has an oxygen transmission rate of 0.07 cc/m 2 ·day·atm to 0.09 cc/m 2 ·day·atm. 
     
     
         10 . The food storage container of  claim 5 , wherein display information is printed on a lower surface of the ivory white layer.
