Abstract:
Disclosed is an airtight container in which a lid is easily opened by the principle of the lever thus preventing broth from splashing out when the lid is opened. The airtight container includes a container body having a latching bump and a bent flange, a rotating knob connected to the flange and having an opening-closing plate and a step portion, and a lid having a latching protrusion, a downwardly bent flange and a lid extension portion, wherein, when the rotating knob is just rotated upward in a state where the lid is coupled to the container body, the opening-closing plate lifts the lid extension portion by “the principle of the lever” while the step portion prevents the lid extension portion from spreading outwards, thereby allowing the latching protrusion to be released from the latching bump and the lid to be opened from the container body.

Claim (Index 1):
An airtight container ( 10 ) including a container body ( 20 ) having an opening formed on an upper portion thereof, a lid ( 30 ) for opening or closing the opening of the container body ( 20 ), and a rotating knob ( 29 ) hingedly-connected to one of the container body ( 20 ) and the lid ( 30 ), the airtight container comprising:\n the container body ( 20 ) including a latching bump ( 24 ) formed along an upper inner wall surface ( 20 b ) of an inner wall ( 20 a ) of the container body and a flange ( 23 ) extending outwardly from an upper portion of the inner wall ( 20 a ) and then bent downward thereby forming a groove ( 22 ) therein; the rotating knob ( 29 ) connected to the flange ( 23 ) and having an opening-closing plate ( 27 ) and a step portion ( 28 ), and being vertically rotatable; and the lid ( 30 ) including a latching protrusion ( 32 ) formed along on an inner wall surface ( 31 a ) of an inner wall ( 31 b ), a downwardly bent flange ( 30 a ) extending outwardly from a circumference of the inner wall ( 31 b ) and capable of being coupled downwardly to the flange ( 23 ), and a lid extension portion ( 33 ) formed at the flange ( 30 a ), wherein the lid extension portion ( 33 ) is in contact with the opening-closing plate ( 27 ) and the step portion ( 28 ) in a state where the lid ( 30 ) is coupled to the container body ( 20 ), or when the rotating knob ( 29 ) is rotated upward in the state where the lid ( 30 ) is coupled to the container body ( 20 ), and wherein, when the rotating knob ( 29 ) is just rotated upward in the state where the lid ( 30 ) is coupled to the container body ( 20 ), the opening-closing plate ( 27 ) lifts the lid extension portion ( 33 ) by \u201cthe principle of the lever\u201d and the step portion ( 28 ) prevents the lid extension portion ( 33 ) contacted with the step portion ( 28 ) from spreading outwards, thereby allowing the latching protrusion ( 32 ) to be released from the latching bump ( 24 ) and the lid ( 30 ) to be opened from the container body ( 20 ).
