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.
