  And when using the packaging box A, the packaging box A is assembled. That is, the front part 110 and the back part 140 in the outer box part A2 are parallel to each other, the side part 120 and the side part 130 are parallel to each other, and the front part 10 and the back part in the inner box part A1. 40 is parallel to each other, the side surface portion 20 and the side surface portion 30 are parallel to each other, and the bottom surface portion 50 is perpendicular to the sleeve-like portions 5 and 105 so that the packaging box A is three-dimensional. Assembled. Moreover, the bottom face part 5 is assembled in a substantially flat plate shape.

  Then, as shown in FIG. 9, a plurality of articles (products) G are stored in the inner box portion A1 from above the packaging box A. In addition, as the to-be-contained object G, it is preferable to make it flexible like pouch products, such as a retort pouch. That is, when the outer box part A2 is separated from the inner box part A1, the outer box part A2 is rotated around the corners P1 and P2, and at this time, the front part 110 of the outer box part A2 is accommodated. Since there is a possibility of coming into contact with the object G, it is preferable that the object is flexible. In addition, since the upper surface parts 160 to 190 are in a state where they are erected upward in advance, and the upper part of the outer box part A2 is open, the storage object G is stored as it is from above the packaging box A. do it. In addition, the front part 110, the side parts 120, 130, the back part 140, the front part 10, the side parts 20, 30, and the back part 40 of the inner box part A1 are in an upright state. Therefore, there is no hindrance to the storage of the items to be stored. Thereafter, the upper surface portions 160 to 190 are closed, and the adhesive tape T is adhered from the front surface portion 110 of the outer box portion A2 to the rear surface portion 140 side through the upper surface, as shown in FIG. ~ 190 is sealed. In other words, by closing the upper surface portions 160 to 190 with respect to the upper opening of the sleeve-like portion 105, the upper opening is closed by the upper surface portions 160 to 190 (mainly by the upper surface portions 170 and 180). Fix it.

  When the items to be stored are packaged in the packaging box A as described above, the packaging box A storing the items to be stored G is transported to a place where the items to be stored G are displayed.

  Thereafter, when displaying the items to be stored, the outer box part A2 is separated from the inner box part A1. As an actual operation, for example, while grasping the exposed portion of the inner box portion A1 with one hand (that is, the portion exposed from the notch portion 122 in the side surface portion 120 and the portion exposed from the notch portion 132 in the side surface portion 130), With the other hand, the front side area of the side part 120 and the upper end of the side part 130 of the outer box part A2 is grasped, and the other hand holding the outer box part A2 is pulled up obliquely upward on the back side. That is, the outer box part A2 is rotated with respect to the inner box part A1 so that the front part 110 of the outer box part A2 rotates obliquely upward on the back side. Then, the outer box portion A2 rotates with respect to the inner box portion A1 with the corner portions P1 and P2 as rotation centers. That is, the outer box portion A2 rotates around a rotation axis connecting the corner portion P1 and the corner portion P2. In addition, since outer box part A2 is rotated centering on corner | angular part P1, P2, it is preferable to operate in the state which mounted packaging box A on the mounting surface.

  That is, by rotating the outer box part A2 to the back side around the corners P1, P2 with respect to the inner box part A1, the separation part 24 is pulled obliquely upward on the back side with respect to the main body part 22, Since the separation part 34 is pulled obliquely upward on the back side with respect to the main body part 32, the cut lines K24 and K34 are broken, and further, the outer box part A2 is rotated, and the side part 120e and the side part of the side part 120 are rotated. The side portion 130e of 130 and the side portion 140a of the back surface portion 140 are in parallel with the placement surface of the packaging box A and are in contact with the placement surface (see FIG. 11). In this state, the side portion 120 e is parallel to the lower side 22 d of the side surface portion 20, and the side portion 130 e is parallel to the lower side 32 d of the side surface portion 30.

  From the state in which the separation part 24 is connected to the main body part 22 via the cut line K24 (that is, the state before the cut line K24 is broken), the side part 120e, the side part 130e, and the side part 140a are connected to the packaging box A. The state of the separating portion 24 until it is in parallel with the placement surface and comes into contact with the placement surface is as shown in FIG. 13, from the state before the cut line K24 is broken (FIG. 13 (a)). By turning the outer box part A2, the cut line K24 is broken, and the separating part 24 is turned around the corner part P1 in a state where it is adhered to the side face part 120 of the outer box part A2 (FIG. 13B). ). At that time, since the gap 23S is formed on the upper side and the back side of the separation part 24 in a state before the cut line K24 is broken, the separation is achieved by rotating the outer box part A2 with respect to the inner box part A1. The cut line K24 can be broken by pulling the part 24 upward with respect to the main body part 22 (that is, with respect to the cut line K24). That is, when the gap 23S is not provided (that is, the main body part is in contact with the upper side and the back side of the separation part 24), the upper part and the back side parts of the separation part 24 in the main body part 22 become an obstacle. Thus, although the separating portion 24 cannot be pulled with respect to the cut line K24, in the case of the present embodiment, since the gap 23S is provided, the separating portion 24 can be pulled with respect to the cut line K24. The cut line K24 can be broken.

  When the rotating separating portion 24 comes into contact with the edge portion of the opening portion 23 (see FIG. 13B), the separating portion 24 is further rotated away from the region in the opening portion 23, and the side portion 120e and the side portion are further rotated. In a state where the portion 130e and the side portion 140a are in parallel with the placement surface of the packaging box A and are in contact with the placement surface, the separation portion 24 is in the state shown in FIG. Since the separation part 24 is a part of a sheet-like blank, the separation part 24 is formed thin, and the blanks constituting the inner box part A1 and the outer box part A2 are formed by a sheet-like blank such as corrugated cardboard. Since there is flexibility, even when the separation part 24 comes into contact with the edge of the opening part 23, the separation part 24 can be easily detached from the opening part 23 by further rotating the outer box part A2. .

  From the state in which the separation part 34 is connected to the main body part 32 via the cut line K34, the side part 120e, the side part 130e, and the side part 140a are parallel to the placement surface of the packaging box A and are placed on the placement surface. The state of the separating unit 34 until it comes into contact is the same as that of the separating unit 24 except that it is symmetric.

  Next, when the side portions 120e and 130e and the side portion 140a are in parallel with the mounting surface of the packaging box A and come into contact with the mounting surface, the outer box portion A2 is moved around the side portion 140a of the back surface portion 140. The outer box A2 is further opened with respect to the inner box A1 by further rotating with respect to the box A1. Thereafter, after the back surface portion 140 is in contact with the placement surface, the outer box portion A2 is pulled away from the inner box portion A1. When the side portions 120e, 130e and the side portion 140a are parallel to the placement surface of the packaging box A and come into contact with the placement surface (the state shown in FIG. 11), the outer case portion A2 is changed to the inner case portion A1. The outer box portion A2 may be separated from the inner box portion A1 by pulling upward with respect to the inner box portion A1, or the side portions 120e, 130e and the side portion 140a are parallel to the mounting surface of the packaging box A and the mounting surface. The outer box portion A2 is pulled upward with respect to the inner box portion A1 at a position between the state in contact with the back surface portion 140 and the state in which the back surface portion 140 is in contact with the mounting surface (state in FIG. 12). May be separated.

  In addition, since the front part 110 of the outer box part A2 falls to the back side when the outer box part A2 rotates around the corner parts P1 and P2, the front part 110 may come into contact with the object G to be stored. However, it is difficult to turn the outer case A2 by making the object to be flexible or by providing a space enough for the object to fall to the back side. There is nothing.

  When the outer box portion A2 is separated from the inner box portion A1, as shown in FIG. 14, display is performed in a state where the articles to be stored G are stored in the inner box portion A1.

  According to the packaging box of the present embodiment, since the outer box part A2 can be separated from the inner box part A1 only by the operation of rotating the outer box part A2 with respect to the inner box part A1, the outer box part A2 can be separated with a small number of steps. The box part A2 can be separated from the inner box part A1.

  Further, since the outer box part A2 is separated with the other hand while the inner box part A1 is held with one hand, there is a hindrance to the separation of the outer box part A2 from the inner box part A1 even when the object to be stored is lightweight. Never come. In other words, as in the case of the above conventional example (utility model registration No. 3139948), when the object to be stored in the inner box is light, the inner box is also lifted upward when separating the outer box. There is no end to it.

  Further, the corner portions P1 and P2 are provided on the side surface portions 120 and 130 of the outer box portion A2, and the corner portions P1 and P2 can be turned as fulcrums, so that the outer box portion A2 is smoothly turned. be able to.

  Moreover, since the opening part 23 is provided in the side part 20 of the inner box part A1, and the separation part 24 is provided in the opening part 23, the separation part 24 is stably supported by the main body part 22 (that is, The separation portion 24 is stably supported by the side surface portion 20), and the opening portion 33 is provided in the side surface portion 30, and the separation portion 34 is provided in the opening portion 33. Is stably supported by the main body portion 32 (that is, the separation portion 34 is stably supported by the side surface portion 30), so that the joint portion between the inner box portion A1 and the outer box portion A2 is stabilized and inadvertent. It is possible to prevent the cut lines K24 and K34 from breaking. That is, as shown in FIG. 15, when the separation part 24 (34) is provided in the notch part 23 ′ (33 ′) whose upper part is opened, the upper part of the notch part 23 ′ (33 ′) is opened. Therefore, the separation portion 24 (34) may not be stably supported and the separation portion 24 (34) may be wobbled. If the separation portion 24 (34) is wobbled, the cut line K24 (K34) is carelessly broken. Although there is a possibility, since the separation part 24 (34) is provided in the opening part 23 (33) as described above, the separation part 24 (34) can be stably supported.

  Moreover, since it is the structure which provided the isolation | separation part 24 (34) in the opening part 23 (33), an unevenness | corrugation is not formed along the upper side of the side parts 20 and 30, and the productivity of the inner box part A1 is improved. be able to.

  Further, since the separation portion 24 (34) is provided at the lateral center of the side surface portion 20 (30), the outer box portion A2 is stably supported by the inner box portion A1.

  Further, in the packaging box A of this embodiment, compared to the above-described conventional example (utility model registration No. 3139948), the side portions 120 and 130 of the outer case portion A2 are not provided with the cut lines, so that the side surface The appearance of the parts 120 and 130 can be improved.

  Moreover, according to the packaging box A of the present embodiment, as shown in FIG. 1 and FIG. Since 190 is only closed and sealed with one adhesive tape T, packing work of goods (goods) can be easily performed.

  In addition, according to the packaging box A of the present embodiment, by separating the separation parts 24 and 34 from the inner box part A1, it is possible to display the items to be stored only by separating the outer box part A2 from the inner box part A1. Therefore, the display work can be easily performed.

  Further, in the display state of the objects to be stored, the length in the height direction of the front portion 10 in the inner box portion A1 is formed to be smaller than the length in the height direction of the back portion 40. By displaying as the front side, it is possible to make it easier for the user to see the stored items.

  Further, as shown in FIG. 15, the inner box portion A1 is provided with a notch portion 23 ′ opened upward on the upper side of the main body portion 22, and a separation portion 24 is provided in the notch portion 23 ′ via a score line K24 ( In other words, the front side and the bottom side of the separation part 24 are connected to the main body part 22 via the cut line K24), and a notch part 33 ′ that opens upward is provided on the upper side of the main body part 32. Alternatively, the separation part 34 may be provided via the cut line K34 (that is, the front side and the bottom side of the separation part 34 are connected to the main body part 32 via the cut line K34). Also in this case, the separation part 24 is formed to be biased toward the front side in the notch part 23 ′, and a gap 23 S is formed between the separation part 24 and the edge part of the notch part 23 ′ on the back side of the separation part 24. The separating portion 34 is formed to be biased toward the front side in the notch 33 ′, and a gap 33S is formed between the separating portion 34 and the edge of the notch 33 ′ on the back side of the separating portion 34. Thus, by rotating the outer box part A2 with respect to the inner box part A1, the separating parts 24, 34 are located above the rear side with respect to the main body part 22 (that is, with respect to the cut lines K24, K34). It is possible to break the score lines K24 and K34 by pulling to.

  In the example of FIG. 15, the separation portion 24 (34) is formed so as to be biased toward the bottom surface side of the cutout portion 23 ′ (33 ′), and the separation portion 24 ( 34), a space is provided on the upper side, but the notch 23 '(33') is open upward, so that the separation part 24 (34) is particularly provided on the bottom surface of the notch 23 '(33'). It is not necessary to form it biased to the side.

  However, as compared with the configuration shown in FIG. 5, the effect of stably supporting the separating portions 24 and 34 on the side surface portions 20 and 30, and unevenness is not formed along the upper sides of the side surface portions 20 and 30, and the inner box portion It can be said that the effect of improving the productivity of A1 is weak.

  In the above description, the side surface portion 20 (30), in particular, the openings 23 and 33 and the separation portions 24 and 34 have the shapes described above. However, the separation portion 24 (34) is the opening portion 23. In (33), by being biased toward the front side and the bottom side, it is formed between the separation part 24 (34) and the edge of the opening 23 (33) on the back side and the upper side of the separation part 24 (34). If the front side and the bottom side of the separation part 24 (34) are connected to the main body part 22 (32) via a score line, the openings 23 and 33 and the separation part The shapes of 24 and 34 may be other shapes. That is, in such a configuration, the outer casing portion A2 is rotated relative to the inner casing portion A1, thereby pulling the separating portion 24 (34) upward and to the rear side with respect to the main body portion 22 (32). The cut line K24 (K34) can be broken.

  Further, the packaging box A may have a left-right symmetric configuration, that is, the inner box portion A1 may have a left-right symmetric configuration, and the outer box portion A2 may have a left-right symmetric configuration.
