Description

  The present invention relates to a packaging box for storing products such as medicines, cosmetics, and beverages, and more particularly to a packaging box with a child resistant function that is difficult for a child to open.

  Conventionally, as shown in FIGS. 26 and 27, this type of packaging box includes a front part 51, a back part 52 facing the front part 51, and a pair of side surfaces straddling the front part 51 and the back part 52. And a top cover piece 54 that seals the top face side of the box, and a bottom cover piece 55 that seals the bottom face side of the box. Further, the packaging box includes a first sheet portion 56, a second sheet portion 57, and a third sheet portion 58 as parts constituting the front portion 51.

  In this packaging box, the pushed-in portion 56a provided in the first sheet portion 56 is pushed from the outside, and the pushed-in portion along the first cut line 59 provided along the edge of the pushed-in portion 56a. 56a is separated from the first sheet portion 56 to be opened.

  Further, the packaging box 1 includes a lock portion 61 and a lock portion 61 that are overlapped on the inner side of the locked portion 59a of the first cut line 59 so as to restrict the opening of the box body to the second sheet portion 57. In order to separate from the seat part 57, it has the 2nd cut line 62 provided in the edge part of the lock part 61 (patent document 1).

  In the conventional packaging box configured as described above, the lock portion 61 of the second sheet portion 57 is overlapped inside the locked portion 59a of the first cut line 59 of the first sheet portion 56, whereby the first sheet is obtained. Even if the pushed-in part 56a of the part 56 is pushed in from the outside, the cut-off part 56a along the first cut line 59 is prevented from being separated by the lock part 61, so that it can be prevented from being easily opened.

  Further, in this packaging box, in order to release the lock by the lock part 61, it is necessary to separate the lock part 61 from the second sheet part 57 along the second cut line 62 of the second sheet part 57. Since a large force is required to separate the portion 61, it is difficult to separate the lock portion 61 with the power of a child, and the lock release by the child can be prevented.
