Sealed container

Abstract

A sealed container comprises a base and a lid is provided. The lid has a top, a lid sidewall, a lid rim and a lid sealing edge extending outward from said lid rim. The base has a bottom, a base sidewall, a base rim and a base sealing edge extending outward from said base rim. The lid sealing edge and said base sealing edge are molded to mate with each other, and upon mating, the downward bending section attaches to the said downward extending section, and the said barb locks and holds up the base sealing edge forming two seals. The embodiments of the present invention improve the sealing structure of the base and the lid thus enhances the sealing effect of the attaching position and the convenience for opening.

1 . A sealed container comprising:
 a base and a lid, wherein the lid has
 a top, 
 a lid sidewall extending downward from the said top, 
 a lid rim extending substantially horizontally outward from said lid sidewall, 
 a lid sealing edge extending outward from said lid rim, wherein said sealing edge comprising an upward bending section in connection with the lid rim, a downward bending section provided with a barb, and a transition section connecting the upward bending section and the downward bending section; 
 and the base has 
 a bottom, 
 a base sidewall extending upward from said bottom, 
 a base rim extending substantially horizontally outward from said base sidewall, 
 a base sealing edge extending outward from said base rim, wherein the base sealing edge comprising an upward extending section in connection with the base rim, a downward extending section and a connecting section connecting the upward extending section and the downward extending section; 
 wherein said lid sealing edge and said base sealing edge are molded to mate with each other, and upon mating, the said downward bending section attaching to the said downward extending section, and the said barb locking and holding up the base sealing edge; 
 wherein the transition section or the connecting section is provided with a first sealing flange, which is pressing against the transition section and the connecting section in between to form a first sealing line; 
 wherein the lid rim or the base rim is provided with a second sealing flange, which is pressing against the lid rim and the base rim in between to form a second sealing line; 
 wherein between the barb and the first sealing flange on the base sealing edge is provided with a corner, and when the lid and the base are joined together, a space is formed at the corner between the lid and the base, forming a sealed air pocket; 
 wherein the lid top is provided with an annular slot, and the base bottom is provided with an annular ledge, the annular slot and the annular ledge having coinciding projections and shaped to match with each other, and when the base is placed on the cover top, the annular ledge is embedded into the annular slot. 
   
     
     
         2 . (canceled) 
     
     
         3 . The sealed container of  claim 1 , wherein between the first sealing flange and the second sealing flange, two corners are provided; when the lid and the base are joined together, at least one space is formed at those two corners, and the corner with the space forms the sealed air pocket. 
     
     
         4 . The sealed container of  claim 1 , wherein the first sealing flange is disposed at a bottom surface of the transition section of the lid sealing edge. 
     
     
         5 . The sealed container of  claim 1 , wherein the second sealing flange is disposed at a bottom surface of the lid rim. 
     
     
         6 . (canceled) 
     
     
         7 . The sealed container of  claim 1 , wherein the base sidewall extends upward in a widening way, forming two step surfaces. 
     
     
         8 . The sealed container of  claim 1 , wherein the base and the lid are approximate cuboids or cubes. 
     
     
         9 . The sealed container of  claim 1 , wherein the base and the lid are approximately cylinders. 
     
     
         10 . The sealed container of  claim 1 , wherein, the base and the lid are made of plastic or rubber material.
