  The first plate portion 11 is one of a plurality of plate portions 10 forming the packaging box 1. In FIG. 2, the plate portion 10 a of the four plate portions 10 a to 10 d corresponds to the first plate portion 11.

  The second plate portion 12 is one of the plurality of plate portions 10 forming the packaging box 1 similarly to the first plate portion 11, and is the plate portion 10 continuous with the first plate portion 11. In FIG. 2, the plate portion 10 d of the four plate portions 10 a to 10 d corresponds to the second plate portion 12. Here, the continuous board part 10 is the board part 10 adjacent after the assembly of the packaging box 1, and does not need to be adjacent before an assembly.

  The first movable piece 110 is a portion formed by bending a part of the first plate portion 11 inward. After the formation of the first movable piece 110, a hole having the same size as that of the first movable piece 110 is formed in a part of the first plate portion 11 at a position where the first movable piece 110 exists. The hole is large enough for the user's finger to enter. The first movable piece 110 has a first distal end 111 showing a distal end of the first movable piece 110, a first proximal end 113 showing a proximal end of the first movable piece 110, and a first distal end 111 And a first bent portion 112 which is bent up to one proximal end portion 113.

  The second movable piece 120 is a portion formed by bending a part of the second plate portion 12 inward. After forming the second movable piece 120, a hole having the same size as the second movable piece 120 is formed in a part of the second plate portion 12 at a position where the second movable piece 120 exists. The hole is large enough for the user's finger to enter. The second movable piece 120 includes a second distal end 121 indicating the distal end of the second movable piece 120, a second proximal end 123 indicating the proximal end of the second movable piece 120, and a second distal end 121 And a second bent portion 122 which is bent between two proximal ends 123.

  The first movable piece 110 and the second movable piece 120 are formed to be symmetrical with respect to a plane F2 which bisects the inner angle of the ridge line portion 13 consisting of the first plate portion 11 and the second plate portion 12 It is possible. Therefore, after the formation of the first movable piece 110 and the second movable piece 120, the size and position of the hole formed in the first plate portion 11 and the size and position of the hole formed in the second plate portion 12 And may be identical to each other.

  The first movable piece 110 and the second movable piece 120 are bent at the first base end 113 and the second base end 123 so that the first tip end portion 111 and the second tip end portion 121 abut against the inside of the ridgeline portion 13 Thus, the handle portion G is configured. The user can carry the packaging box 1 with one hand by putting a finger in the hole formed after the formation of the first movable piece 110 and the second movable piece 120 and gripping the handle portion G.

  The window part 14 is a window part which can visually recognize the appearance of the article P stored in the internal space of the packaging box 1. A transparent film such as cellophane is attached to the window portion 14 in order to prevent the articles P stored in the packaging box 1 from protruding or falling out. The window portion 14 is formed in the first plate portion 11 or the second plate portion 12.

  FIG. 3 is a view showing a process of forming the handle portion G of the packaging box 1 according to Embodiment 1 of the present invention. FIG. 3A shows the state of the first movable piece 110 and the second movable piece 120 before the formation of the handle portion G. FIG. FIG. 3B shows the state of the first movable piece 110 and the second movable piece 120 during formation of the handle portion G. As shown in FIG. FIG. 3C shows the state of the first movable piece 110 and the second movable piece 120 after the formation of the handle portion G.

  As shown in FIG. 3A, in order to form a first movable piece 110 by bending a part of the first plate portion 11, the contour portion of the first movable piece 110 is It has a letter-shaped cutting process. Furthermore, the first plate portion 11 is subjected to a line processing so that the first bent portion 112 and the first base end portion 113 serving as a fold line can be easily bent. Further, the second plate portion 12 is subjected to the same processing as the first plate portion 11.

  As shown in FIG. 3 (b), the first movable piece 110 is configured such that the first movable end 110 is moved toward the inner side of the ridgeline portion 13 by pushing the first tip end 111 inward from the state of FIG. 3 (a). It bends at the bending portion 112. Further, the second movable piece 120 is also bent at the second bending portion 122 in the same manner as the first movable piece 110.

  As shown in FIG. 3C, in the first movable piece 110, the first distal end portion 111 is the inner side of the ridgeline portion 13 by the first bent portion 112 being pushed inward from the state of FIG. 3B. It bends at the first proximal end 113 toward the end. Then, the first front end portion 111 of the first movable piece 110 abuts on the inside of the ridge portion 13. Further, the second movable piece 120 is also bent at the second base end portion 123 so that the second tip end portion 121 abuts on the inner side of the ridgeline portion 13 similarly to the first movable piece 110. In such a process, the handle portion G is formed.

  FIG. 4 is a view showing a cross section of the handle portion G of the packaging box 1 according to Embodiment 1 of the present invention. FIG. 4 schematically shows a cross section obtained by cutting the first movable piece 110 and the second movable piece 120 after forming the handle portion G in the xz plane.

  The first movable piece 110 and the second movable piece 120 are bent at the first base end 113 and the second base end 123 so that the first tip end portion 111 and the second tip end portion 121 abut against the inside of the ridgeline portion 13 Thus, the handle portion G is configured. For this reason, the handle portion G is not formed to protrude outward from the plate portion 10 of the packaging box 1. Thus, the packing box 1 can be stacked in a well-balanced manner.

  Furthermore, the first movable piece 110 and the second movable piece 120 are formed by bending a part of each of the first plate portion 11 and the second plate portion 12 inward. For this reason, in the handle portion G, the user's finger does not contact the cross-sectional portion of the first plate portion 11 and the second plate portion 12 in the thickness direction, but the finger of the first plate portion 11 and the second plate portion 12 It abuts on the surface portion and is gripped by the user. Therefore, in the packing box 1, the user can grip the surface portions of the first plate portion 11 and the second plate portion 12, so that the burden on the finger can be reduced.

  Furthermore, in the first movable piece 110 and the second movable piece 120, the first tip end portion 111 and the second tip end portion 121 abut against the inside of the ridge portion 13. For this reason, in the handle portion G, the force applied to the first base end 113 and the second base end 123 can be transmitted from the first distal end 111 and the second distal end 121 to the inside of the ridgeline portion 13. As a result, in the handle portion G, a shear force to peel off the first base end portion 113 and the second base end portion 123 from the first plate portion 11 and the second plate portion 12 can be reduced. . Therefore, in the packaging box 1, since the shear force generated at the root of the handle portion G is reduced, the strength of the handle portion G can be increased. In addition, the first movable piece 110 and the second movable piece 120 do not collide with the ridgeline portion 13 each time the handle portion G is gripped, and the first distal end A striking force is not generated in the portion 111 and the second tip portion 121. Therefore, in the packaging box 1, the handle portion G is less likely to deteriorate.

  Further, in the first movable piece 110 and the second movable piece 120, the distance c1 from the first bending portion 112 to the first distal end portion 111 is from the plane F1 including the first base end 113 and the second base end 123. It is longer than the distance d to the inside of the ridgeline portion 13. Similarly, the distance c2 from the second bent portion 122 to the second tip end portion 121 is longer than the distance d. For this reason, the handle portion G is not mainly supported by the first base end 113 and the second base end 123, as in the case where the distances c1 and c2 are equal to or less than the distance d, when grasped. The first bent portion 112 and the second bent portion 122 are mainly supported. As a result, in the handle portion G, the force applied to the first base end 113 and the second base end 123 by the addition of the first bending portion 112 and the second bending portion 122 is the first bending portion 112 and the second bending portion 122. It may be dispersed in the second bending portion 122. Therefore, in the packaging box 1, since the stress concentration generated in the handle portion G can be alleviated, the strength of the handle portion G can be further enhanced.

  In addition, the first bendable portion 112 and the second movable piece 120 have the first bending portion 112 and the first bendable portion 112 so that the first tip end portion 111 and the second tip end portion 121 face the inner side of the ridgeline portion 13 and abut It is bent at the second bending portion 122. For this reason, in the handle portion G, the force applied to the first bending portion 112 and the second bending portion 122 when being gripped is from the portion from the first bending portion 112 to the first tip portion 111 and from the second bending portion 122 It is transmitted to the portion up to the second tip 121. Then, in portions from the first bending portion 112 to the first tip end portion 111 and in portions from the second bending portion 122 to the second tip portion 121, a reaction force against a force for compressing these portions is generated, and the first bending portion is generated. The force applied to the portion 112 and the second bending portion 122 can be further reduced. Thereby, the force applied to the first proximal end 113 and the second proximal end 123 can be further reduced by reducing the force transmitted from the first bending portion 112 and the second bending portion 122. As a result, in the handle portion G, the shear force to peel off the first base end portion 113 and the second base end portion 123 from the first plate portion 11 and the second plate portion 12 is substantially large. It can be reduced. Therefore, in the packaging box 1, the shear force generated at the root of the handle portion G is significantly reduced, so the strength of the handle portion G can be further increased.

  Further, in the first movable piece 110 and the second movable piece 120, the portion from the first bending portion 112 to the first tip portion 111 and the portion from the second bending portion 122 to the second tip portion 121 abut each other . Under the present circumstances, since the 1st movable piece 110 and the 2nd movable piece 120 are mutually symmetrical, the restoring force which tries to return the 1st base end part 113 and the 1st bending part 112 back, and the 2nd base end part The restoring force that tries to restore 123 and the second bending portion 122 is offset. Therefore, the contact state of the first movable piece 110 and the second movable piece 120 is maintained. Therefore, in the packaging box 1, the shape of the handle portion G is maintained, so that the load on the finger can be stably reduced and the strength of the handle portion G can be stably increased.

  The first movable piece 110 and the second movable piece 120 have a distance a1 from the first bending portion 112 to the first base end portion 113, and a distance a2 from the second bending portion 122 to the second base end portion 123, and Are equal to one another. The sum of the distance a1 from the first bending portion 112 to the first base end 113 and the distance a2 from the second bending portion 122 to the second base end 123 is the first base end 113 and the first base end 113. It is longer than the distance b between the two base end portions 123. For this reason, the first movable piece 110 and the second movable piece 120 protrude from the plane F1 including the first base end 113 and the second base end 123 to the opposite side of the ridgeline portion 13 and the protruding shape is an isosceles triangular prism It can be As a result, in the handle portion G, the shape of the projecting isosceles triangular prism can follow so as to conform to the shape of the user's finger. Therefore, in the packing box 1, the burden on the finger can be further reduced.

  In addition, the first movable piece 110 and the second movable piece 120 are formed to be symmetrical with respect to a plane F2 that bisects the inner angle of the ridgeline portion 13. Therefore, in the handle portion G, the entire shape of the handle portion G including the holes formed in the first plate portion 11 and the second plate portion 12 is a plane F2 in which the angle inside the ridge portion 13 is bisected. Can be symmetrical. Therefore, in the packing box 1, even when the user grips the handle G from the side of the first plate 11 with the window 14, the user grips the handle G from the side of the second plate 12 without the window 14. However, the handle portion G can be gripped in the same manner.

  In particular, in the handle portion G, a truss structure formed by including the first tip end portion 111, the first bending portion 112, and the first base end portion 113, the second tip end portion 121, the second bending portion 122, and the second The truss structure formed including the base end portion 123 has the same structure. Therefore, in the packaging box 1, the strength of the handle portion G can be further increased.

  Moreover, the window part 14 which can visually recognize the mode of the articles | goods P accommodated in the internal space of the packaging box 1 is formed in the 1st board part 11 or the 2nd board part 12. FIG. Therefore, the user can carry the packing box 1 while visually recognizing the state of the article P stored in the inside of the packing box 1 or the storage state of the packing box 1, for example. Further, in the packing box 1, when the handle G is held so that the window 14 is on the opposite side to the user's body, the appearance of the article P or the decoration in the packing box 1 is shown to the outside. For this reason, the user can also advertise the decoration in the article P or the packaging box 1 while carrying the packaging box 1.

  As described above, the packaging box 1 according to the first embodiment allows the user to grip the surfaces of the first plate portion 11 and the second plate portion 12, and therefore the burden on the finger can be reduced. Furthermore, in the packaging box 1 according to the first embodiment, the shear force generated at the root of the handle portion G is reduced, and the first tip end portion 111 and the second tip end portion 121 can be made difficult to deteriorate.

Therefore, the packing box 1 which concerns on Embodiment 1 reduces the burden on a user's finger, makes the intensity | strength of a handle part high, and enables it to be piled up in balance.

  In the packaging box 1 according to the first embodiment, the distances c1 and c2 are longer than the distance d, and the portion from the first bending portion 112 to the first tip portion 111 and the second bending portion 122 to the second tip portion 121 And the parts of the contact with each other. For this reason, since the packaging box 1 which concerns on Embodiment 1 can relieve | moderate the stress concentration concerning the handle part G, the intensity | strength of the handle part G can be made high. Furthermore, in the packaging box 1 according to the first embodiment, since the shear force generated at the root of the handle portion G is significantly reduced, the strength of the handle portion G can be further increased. Furthermore, since the packaging box 1 according to the first embodiment can maintain the shape of the handle portion G, it is possible to stably reduce the burden on the user's finger and stabilize the strength of the handle portion G. Can be made more expensive.

  Moreover, in the packaging box 1 according to the first embodiment, the distances a1 and a2 are equal to each other, and the total thereof is longer than the distance b. Therefore, in the packing box 1 according to the first embodiment, the shape of the handle portion G protruding from the plane F1 to the opposite side of the ridgeline portion 13 follows the shape of the user's finger, and the load on the finger is reduced. It can be further reduced.
