According to the present invention, a packaging box has an upper side which is horizontally formed when first and second deformation units (52, 54) are received to each other. A load is applied to the first and second deformation units (52, 54) to automatically protrude to have one shape among a trapezoidal shape, triangular shape, or curved shape when a user pulls a handle (20). First and second engagement units (55, 56) are formed to be engaged to each other to prevent the first and second deformation units (52, 54) from being separated when the first and second deformation units protrude upward. |
