PROBLEM TO BE SOLVED: To provide a packaging box used for cosmetic or the like, further reliably preventing fraudulent opening.SOLUTION: In a so-called rectangular parallelepiped-shaped sack box configured by blocking both opening ends 17 of a square cylindrical trunk 10 by a lid 16, tongue pieces 23 and 21 are provided in an insertion flap 22 formed by extending from the tips of the lids 16 and 16a, and a wall surface 14 opposing thereto. With this, the tongue piece 23 at an insertion flap 22 side runs over the tongue piece 21 at an opposite wall surface side by inserting the insertion flap 22 from the opening end 17, and when the insertion flap 22 is pulled out from the opening end 17 thereafter, the tongue piece 23 is engaged with the tongue piece 21. Thus, once the lids 16 and 16a are closed, fraudulent opening is prevented, the tongue piece 23 is inserted between the tongue piece 21 and the wall surface 14 so as to inhibit the opening, and a strong engagement structure is achieved by overlapped widths of the tongue pieces 21 and 23 so as to reliably prevent fraudulent opening.SELECTED DRAWING: Figure 1 【課題】化粧品などに使用される包装箱において、不正な開封をより確実に防止する。【解決手段】四角筒状の胴部１０の両開口端１７を蓋１６で閉塞して構成される直方体状の、いわゆるサック箱において、蓋１６，１６ａの先端から延びて形成される差込みフラップ２２と、それに対向する壁面１４面とに舌片２３，２１を設ける。したがって、差込みフラップ２２が開口端１７から差し込まれることで該差込みフラップ２２側の舌片２３が対向する壁面側の舌片２１を乗越え、その後に差込みフラップ２２が開口端１７から引抜かれようとすると、舌片２３が舌片２１に係合する。これによって、一旦蓋１６，１６ａを閉じると不正開封を防止できるとともに、その開封の阻止には舌片２１と壁面１４との間に舌片２３が差込まれることになり、舌片２１，２３の相互に重なり合う幅同士で強固な係合構造を実現し、不正開封を確実に防止することができる。【選択図】図１
