Abstract: A packaging container includes a body plate defined into front and back faces by a first folding line. The front face includes second and third folding lines. The second and third folding lines define two connection portions. The body plate further includes an enclosing plate. A fourth folding line is located between the front face and the enclosing plate. The back face is folded upwards along the first folding line, and the connection portions are folded inwards along the second and third folding lines. The connection portions are stuck to the back face. A first pre-folding line and a second pre-folding line are located between the second and third folding lines. A fifth pre-folding line and a sixth pre-folding line are located on the back face. Two seventh pre-folding lines and two eighth pre-folding lines are defined.
