As shown in Figures 1 to 3, the food container sealed container comprises an inner body 10, the outer body 20, the coupling member 30, the lid 40.

The inner body 10 has an opening formed at an upper side thereof, and an accommodation space therein, and serves to accommodate food therein, and is made of stainless steel so as not to cause environmental hormone leakage.

The outer body 20 is coupled to the inner body 10 to surround the outer surface of the inner body 10, the upper side is open and has an inner surface corresponding to the outer surface shape of the inner body 10. The outer body 20 is made of a synthetic resin material, the outer body 20 is covered by the outer surface of the inner body 10, even if the user grabs by hand, the heat or cold of the stored food is not directly transmitted and kept warm and There is an advantage that the cold storage efficiency is excellent.

Here, looking at the coupling relationship between the inner body 10 and the outer body 20, first the inner body 10 has a first bending member 11 at the top, the outer body 20 has a second bending member at the top 21, wherein the first bending member 11 of the inner body 10 forms an annular groove (not shown) and the second bending member of the outer body 20 in the annular groove. As the 21 is press-fitted and fixed, the inner body 10 and the outer body 20 are coupled.

More specifically, as shown in FIG. 3, the first bending member 11 of the inner body 10 is bent downward from the upper end of the inner body 10 and then bent downward to have an annular groove ( (Not shown). In addition, the second bending member 21 of the outer body 20 is formed by bending outward from the upper end of the outer body 20, the second bending member 21 is the first bending of the inner body 10 It has a shape that can be fitted to the annular groove formed by the member (11).

In this case, when the second bending member 21 of the outer body 20 is fitted and coupled to the first bending member 11 of the inner body 10, the inner body 10 may be prevented from falling downward in the drawing. The end of the first bending member 11 of the body 10 is preferably bent in a predetermined length in the inward direction.

As a method of coupling the inner body 10 and the outer body 20 may be employed as follows. One, the first bending member 11 is formed on the upper end of the inner body 10 to form an annular groove, the second bending member 21 is formed on the upper end of the outer body 20, and then the inner body 10 and the outer body 20 by pressing up and down the second bending member 21 is a method to press-fit fixed to the annular groove.
