Generally, vegetables, fruits, food to be cooked, cooked foods and the like are stored for a long time without damaging them. 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 fixing plate portion 22 surrounds the edge of the elastic plate portion 21. The fixing plate portion 22 is harder than the elastic plate portion 21 and can have a slight elasticity but can substantially maintain the outer shape of the lid unit 20. [

The sealing plate 24 may be formed in the fixing plate 22. [

Although not shown, at least one of the container unit 10, the lamination unit 50, and the lid unit 20 may be provided with a handle (not shown) for holding the user. The handle (not shown) is detachable from the container unit 10, the lamination unit 50, or the lid unit 20. When the container (10) or the stacking unit (50) or the lid unit (50) is moved or transported, the user can easily move or transport the hermetically sealed container 20, and contents contained in the accommodation space 11 and the lamination space 51 can be prevented from being deteriorated by the user's body temperature.

The packing unit (30) seals between the container unit (10) and the lamination unit (50) and the lid unit (20) which are coupled to each other. The packing unit (30) has elasticity and is elastically deformed by an external force.

For example, the packing unit 30 may be provided in the lid unit 20. The packing unit 30 may be integrally formed with the lid unit 20. The packing unit 30 may be formed integrally with the lid unit 20 through a double injection molding or a separate molding process. The packing unit 30 may be provided in the container unit 10 or the stacking unit 50.

The packing unit (30) can be removably inserted into the sealing groove (24). The packing unit 30 can be inserted into the sealing groove 24 so that the close contact locking part 33 and the close contact fixing part 34 are exposed or protruded.

The pressing support part 36 can connect the upper end of the through hole 32 and the dispersion supporting part 38 with respect to the height direction of the packing body part 31. [ Although not shown, the pressing support part 36 connects the upper end of the through hole 32 with the lower end of the through hole 32 with respect to the height direction of the packing body part 31, As shown in Fig.

When the packing unit 30 is elastically deformed, the pressing support unit 36 restricts the elastic deformation of the packing body unit in the height direction, and the tightening locking unit 33 and the close- It can be suppressed or prevented from being inserted into the sealing groove 24.

The dispersion supporting portion 38 extends downwardly inclined from the pressing support portion 36. The dispersion supporting portion 38 may connect the end portion of the close contact locking portion 33 along the circumferential direction of the pressing support portion 36 and the packing body portion 31. [ The dispersion supporting portion 38 may connect the pressing support portion 36 with the side of the close contact portion 34.

When the packing unit 30 is elastically deformed, the dispersion supporting unit 38 expands the contact locking unit 33 to expand the contact area of the close contact locking unit 33, So that it is possible to suppress or prevent the tightly fitting part 34 from being inserted into the sealing groove 24.

The rotary contact unit 40 is formed such that the two members are mutually engaged in accordance with the relative rotation between the container unit 10 and the laminate unit 50 and the lid unit 20 which are coupled to each other.

The rotationally adhered unit 40 is formed in such a manner that the two members are engaged with each other by engagement in accordance with relative rotation between the container unit 10 and the lamination unit 50 in the first modification. Further, the rotary contact unit 40 is described in the second modified example in which the two members are formed so as to be engaged with each other by engagement in accordance with relative rotation between the first and second lamination units of the lamination unit 50 .
