CONSTITUTION: A coupling structure of a locking unit for a sealed container includes a storage unit(10) for storing food, a sealing unit(20) covering the upper side of the storage unit, and the locking unit(40). The storage unit includes a flange having a fitting space(14) on the upper side along to the boundary surface. The sealing unit includes a coupling groove. The locking unit is selectively combined to the sealing unit for interlocking the storage unit and the sealing unit. The locking unit includes a fixing plate(42), a pressing plate(44), and a jamming plate(46).
