Description

  The present invention relates to a double packaging case such as a cardboard box for packaging a product such as an electronic device, and more particularly to an opening / closing mechanism for a lid portion of an inner box.

  Conventionally, double packaging cases made of paper or cardboard have been widely used. A perspective view of such a double packaging case is shown in FIG. As shown in FIG. 7, the packaging case 100 includes an inner box 10 and an outer box 20 that houses the inner box 10. The inner box 10 has a box body 11 with an open upper surface of the storage box, and a lid portion 12 extending on one side of the opening end of the box body 11, and the free end of the lid portion 12 when the lid portion 12 is closed. By inserting the insertion portion 12a formed by bending the inside into the opening 14 of the box 11, the lid portion 22 can be held in a closed state.

  On the other hand, the outer box 20 has a box body 21 whose upper surface is opened and flaps 23 a, 23 b, 23 c, and 23 d that extend on the four sides of the opening end of the opening 22 of the box body 21. The flap 23a is provided on the front side of the box 21, the flap 23b is provided on the left side, the flap 23c is provided on the back side, and the flap 23d is provided on the right side. Then, for example, the flaps 23b and 23d are folded inward from the respective opening ends, then the flaps 23a and 23c are folded inward from the respective opening ends, and are overlapped with the flaps 23b and 23d, and then the flaps 23a and 23c are appropriately fixed. Accordingly, the flaps 23a to 23d can be held in the closed state.

  In such a double packaging case, after unpacking the outer box 20, it is difficult to pull out the lid 12 when unpacking the inner box 10 while being stored in the outer box 20. On the other hand, for example, a box as shown in FIG. 8 may be used as the inner box. FIG. 8 is a perspective view of the inner box in which the lid is easily opened. As shown in FIG. 8, in order to easily pull out the lid 12 of the inner box 10, a circular cutout hole 12b is formed at the center of the fold line across the fold line of the insertion portion 12a in the lid 12, At the upper end of the side surface of the inner box 10 that overlaps the insertion portion 12a, an arcuate cutout portion 15 is formed at a position facing the cutout hole 12b.

  When the inner box 10 is stored in the outer box 20, it becomes easier to open by hooking the cutout 12 a with fingers. However, since the side surface of the inner box 10 overlaps the side surface of the outer box 20, when the lid portion 12 is pulled out, if the inner box 10 is stored in the outer box 20, holes formed in the side surface of the inner box 10 are not formed. It cannot be used and the movement of fingers is limited. Thus, the conventional double packaging case has a problem that it is difficult to open the lid 12 of the inner box.

As a method for facilitating the opening of the lid, for example, Patent Document 1 discloses that a handling hole is formed on the side of the packaging box in a packaging box for packaging and storing accessories such as electronic devices, manuals, and AC cords. At the same time, a lid on which the accessory can be inserted in the packaged state is formed on the longitudinal extension of the handle hole, and a perforation that is opened at the time of use is provided in the handle hole and a part of the lid. A technique is disclosed in which the pitch is made larger than the pitch of the perforation of the handle hole, thereby making it easy to open the handle hole often used for transportation and making it difficult to open a lid that is not normally used.
