At the same time, packing is built in the lid so that the characteristic odor of the food does not leak out. Closed containers that are sealed together as much as possible have often been used.

The hermetically sealed container includes a container body having an open upper portion, a lid coupled to an upper opening portion of the container body, a packing groove formed along the tip of the bottom surface of the lid to prevent a gap between the lid and the container body, And a wing member which is formed in a streamline shape while a part of the packing is extended outward along the outer periphery of the lid. Particularly, the wing member is integrally formed with the outer periphery of the lid. At this time, since the thickness of the hinge portion is thin, the wing member rotates freely about the hinge portion and is engaged with the engaging jaw to seal the inside of the container body .

The hermetically sealed container includes a container body having an open upper portion, a lid coupled to an upper open portion of the container body, a packing groove formed along the tip of the bottom surface of the lid to prevent a gap between the lid and the container body, And the lid is rotated so that the thread formed on the outer peripheral edge of the upper end of the container and the thread formed on the inner peripheral edge of the lid are engaged to seal the inside of the container body.

However, such a hermetically sealed container has a problem in that the hinge portion is deformed and broken due to repetitive pivotal movement of the wing member, the wing attachment is separated from the lid, or the adhesion between the packing and the container body is lowered.

The close lock portion 33 is formed to be long along the longitudinal direction of the packing body portion 31, and a plurality of the close lock portions 33 may protrude or sink. Accordingly, a plurality of the close lock portions 33 can have a concave-convex cross section on a part of the periphery of the packing body portion 31. [ Here, the cross-sectional shape of the close lock portion 33 is not limited, and various shapes such as a circular cross-section, an elliptic cross-section, and a polygonal cross-section can be achieved.

The tight contact locking portion 33 is elastically deformed in the mutual engagement of the container unit 10 and the lamination unit 50 and the lid unit 20 so that the container unit 10 and the lamination unit 50, And is tightly supported between the lid units 20.

The tightly fitting part 34 is protruded or depressed from the edge of the close lock part 33 along the circumferential direction of the packing body part 31 to the outer circumferential surface of the packing body part 31. The tightly fitting part 34 may be formed to be long along the longitudinal direction of the packing body part 31. The tightly fitting part 34 may be formed on both sides of the close lock part 33 as shown in FIG. Accordingly, the close lock portion 33 may be provided between the close contact portions 34. The tightly fitting part (34) may be formed on one side of the close lock part (33).

The tightly fitting part (34) is supported at the inlet of the sealing groove (24), so that the close contact part (33) can be prevented from being inserted into the sealing groove (24) according to the elastic deformation.
