To provide a packing box which enables easy insertion of an insert part into an insertion hole.SOLUTION: A packing box 1 formed by a corrugated cardboard sheet comprises: a peripheral wall W formed into a cylindrical shape by a pair of first side walls 10 and a pair of second side walls 11; a pair of upper outer flaps 12 connected to the pair of first side walls 10; and a pair of upper inner flaps 13 connected to the pair of second side walls 11. Insertion holding lines L6 are formed in the upper outer flaps 12. An engaging piece 21 is sectioned by cutting in insertion cutting lines in the upper inner flaps 13. Each insertion cutting line has a first cut 22A and a second cut 22B. An edge along an engagement piece 21 and the second cut 22B is a first thin part. The engagement piece 21 is pushed in to form an insertion hole 21A by pressing an insertion part 25 of the upper outer flap 12 bent at the insertion folding line L6 to the engagement piece 21. The insertion part 25 is inserted into the insertion hole 21A by elongating the upper outer flap 12 bent at the insertion folding line L6.SELECTED DRAWING: Figure 1 【課題】差込穴に対して差込部を容易に差し込むことができる包装箱を提供する。【解決手段】段ボールシートで形成される包装箱１は、一対の第１側壁１０と一対の第２側壁１１とで筒状に形成される周壁Ｗと、一対の第１側壁１０に連設される一対の上外フラップ１２と、一対の第２側壁１１に連設される一対の上内フラップ１３と、を備え、上外フラップ１２には差込折線Ｌ６が形成され、上内フラップ１３には差込切断線を切り込むことで係合片２１が区画され、差込切断線は、第１切目２２Ａと第２切目２２Ｂとを有し、係合片２１および第２切目２２Ｂ沿いの縁部は第１薄肉部とされ、差込折線Ｌ６で屈曲した上外フラップ１２の差込部２５が係合片２１に押し付けられることで、係合片２１が押し込まれて差込穴２１Ａを形成し、上外フラップ１２が差込折線Ｌ６での屈曲を伸ばされることで、差込部２５が差込穴２１Ａに差し込まれる。【選択図】図１
