According to this configuration, it is possible to connect a plurality of packaging boxes without separately using an adhesive or a band. Moreover, in this embodiment, the weight (for example, about 6 kg) of the package including the weight of the three containers 100 that are contained is applied to the fitting portion, and the packaging boxes are strongly fitted to each other. . This fitting is difficult to come off even if there is vibration in the width direction and the length direction. This is because the thickness of the packaging box that constitutes the engaging portion comes into contact with the thickness of the packaging box that constitutes a portion having a complementary shape with respect to the engaging portion, thereby preventing the movement of the engaging portion.

  The packaging box 10 according to the present embodiment is particularly suitable when the demand for reduction in storage space is high. With regard to articles, particularly daily commodities that are frequently used (for example, containers filled with drinking water), a plurality of cardboard packaging boxes containing a certain amount of daily commodities are purchased. And although a user takes home several purchased packaging boxes and puts them in a residence, there are not many residences which have a large storage space like the warehouse of a manufacture and sales company. Therefore, in order to realize a reduction in storage space, it is easier to take a method of stacking than packaging a plurality of packaging boxes. Here, for example, even if the projections and notches described in Patent Document 1 are applied to the plurality of packaging boxes, the projection box has a low rigidity when the packaging box is made of paper such as cardboard. May be easily deformed and may not sufficiently exhibit the effect of preventing cargo collapse.

  In this embodiment, even if the packaging box is made of paper such as cardboard, the engaging portion and the portion having a complementary shape are engaged with each other and can be effectively fitted. As a result, since the outer flap portions are fitted to each other so that the plurality of packaging boxes are integrally connected, it is possible to stably pile up and suppress collapse of the load. Further, as described above, it is possible to stack vertically, that is, to stack in a small occupied area, so that the storage space can be reduced.

  Further, the packaging box 10 according to the present embodiment is provided such that the shapes of the two outer flap portions bonded to the same inner flap portion are different from each other, and the shapes of the two outer flap portions facing each other are mutually different. It is provided differently. Referring to FIG. 3, first and fourth outer flap portions 311 and 342 having different shapes are bonded to the first and fourth inner flap portions 221 and 232, respectively. Second and third outer flap portions 312 and 341 having different shapes are bonded to 222 and 231, respectively. Further, the opposing first and second outer flap portions 311 and 312 have different shapes, and the opposing third and fourth outer flap portions 341 and 342 have different shapes. With this configuration, the packaging box 10 can be stacked upside down. That is, it is possible to select which of the two directions in the width direction shown in FIG.

  The effect of the present invention is that the article accommodated in the packaging box 10 according to the present embodiment is particularly a container having a weight that can be stably fitted, for example, a container filled with a liquid such as drinking water. It is preferable when exhibiting. In addition, although the container 100 accommodated in the packaging box 10 which concerns on this embodiment is for 2 liters, in this invention, it is not restricted to this, What kind of capacity | capacitance may be sufficient, and the packaging box 10 The number of containers 100 accommodated is not limited to three. The reason why the packaging box 10 according to the present embodiment accommodates three containers 100 filled with 2 liters of liquid is that the weight and size are suitable for carrying by the user.

  The packaging box 10 according to the present embodiment is designed so that its outer dimensions are about 295 mm in the height direction, about 310 mm in the width direction, and about 100 mm in the length direction. This outer dimension is an example of an optimum dimension for exhibiting the effect of being able to stably pile up when three PET bottles filled with 2 liters of drinking water are accommodated. Note that the optimum outer dimensions of the packaging box according to the present invention are not limited to this, and are appropriately determined depending on the type, size, weight, quantity, etc. of the articles to be accommodated.

  In the packaging box according to each of the above embodiments, the first outer flap portion 311 and the second outer flap portion 312 are connected to the first surface portion 11, respectively, and the third outer flap portion 341 and the fourth outer flap portion 342 are the fourth surface portion. However, the present invention is not limited to this, and may be formed as a separate body without being connected thereto. Moreover, in the packaging box which concerns on each said embodiment, although two complementary shapes with respect to an engaging part and an engaging part are formed, respectively, in this invention, it is not restricted to this. In the following (A) to (D), four modified examples will be given.

  In the description of the present specification and claims, the “planar member” is not limited to a separate body, and is referred to as including an outer flap portion connected to the surface portion of the packaging box. The “planar member” is bonded so that one of its front and back surfaces overlaps one surface portion of the three pairs of surface portions of the packaging box. The surface to be bonded of the planar member may be the entire surface or a part of the surface. Regarding the first to fourth planar members described below, the first planar portion and the third planar portion each have an engaging portion, and the second planar portion and the fourth planar portion correspond to the engaging portion. Each has a complementary shape.

  (A) As a modification, the packaging box according to the present invention includes either a first planar member having an engaging portion or a second planar member having a complementary shape to the engaging portion. . (A1) When the first planar member is bonded so as to overlap one of the pair of surface portions of the three pairs of surface portions of the packaging box, the second planar member has a position where the complementary shape corresponds to the engaging portion. In other words, the other packaging box connectable to the packaging box is bonded to one of the pair of surface portions. (A2) When the second planar member is bonded so as to overlap with one of the pair of surface portions of the three pairs of surface portions of the packaging box, the first planar member has an engaging portion formed in a complementary shape. It adhere | attaches so that it may overlap with one of a pair of surface part which another packaging box has so that it may be arrange | positioned in a corresponding position. With this configuration, since the engaging portion or the complementary shape is formed only on one surface portion of the six surface portions of the packaging box, for example, when the packaging box is installed on the floor, the surface that does not have the engaging portion or the complementary shape. It can be set as an installation surface, and stability when the packaging box is placed can be ensured. Moreover, since it becomes possible to fit the engaging part formed in one packaging box and the complementary shape part formed in the other packaging box among two packaging boxes, it can pile up stably. It becomes possible.

  (B) As a modification, the packaging box according to the present invention includes two members, a first planar member and a second planar member. The first planar member is bonded so as to overlap one of the pair of surface portions of the three pairs of surface portions of the packaging box, and the second planar member is formed at a position where the complementary shape corresponds to the engaging portion. In this way, the bonding is performed so as to overlap one of the pair of surface portions. With this configuration, since the engaging portion and the complementary shape are formed only on one surface portion of the six surface portions of the packaging box, for example, when the packaging box is installed on the floor, it is engaged as in the modification (A). The surface which does not have the part and the complementary shape can be used as the installation surface, and the stability when the packaging box is placed can be ensured. Further, since the planar members are fitted to each other so that the two packaging boxes are integrally connected, it is possible to stably pile up. Furthermore, since it is possible to obtain the effect of this modified example by preparing two types of packaging boxes, compared with the modified example (A) when two types of packaging boxes are prepared one by one. The manufacturing cost can be reduced. Further, since the number of fitting portions is increased as compared with the modified example (A) in the case where there is only one fitting portion, it is possible to connect more integrally and stack more stably.

  (C) As a modification, the packaging box according to the present invention includes a first planar member, a second planar member, a third planar member, and a fourth planar member. The first planar member is bonded so as to overlap one of the pair of surface portions of the three pairs of surface portions, and the second planar member is bonded so as to overlap the other of the pair of surface portions. Further, the third planar member is bonded so as to overlap the other of the pair of surface portions so that the engaging portion is disposed at a position corresponding to the complementary shape forming portion, and the fourth planar member is Are bonded so as to overlap with one of the pair of surface portions so that the complementary shape of the surface is formed at a position corresponding to the engaging portion. With this configuration, as in the above embodiments, the planar members are fitted together so that a plurality of packaging boxes are connected together, so that stable stacking is possible and load collapse is prevented. It becomes possible to deter.

  (D) As a modification, in the packaging box according to the present invention, the first planar member is disposed on the third edge L3 side as a separate body instead of the first outer flap portion 311, and the first inner flap portion 221. The second planar member is disposed on one side of the fourth edge L4 side and the tenth edge L10 side as a separate body instead of the second outer flap part 312. Then, the second inner flap part 222 and the third inner flap part 231 are bonded so as to overlap. The third planar member is disposed on the other side of the fourth edge L4 side and the tenth edge L10 side as a separate body instead of the third outer flap part 341, and the second inner flap part 222 and the third inner member The fourth planar member is disposed on the eleventh edge L11 side as a separate body instead of the fourth outer flap portion 342, and is bonded to overlap the flap portion 231. The first inner flap portion 221 and the fourth inner flap portion 232 is bonded to overlap. With this configuration, it is possible to obtain the same effects as in the above embodiments.
