A hanging part 8 is connected to the upper end of the front plate 3 via a fold line 90. Holes 87a and 87b are formed in the front and back surfaces of the hanging part 8, respectively. First bottom plates 63 and 65 are connected to lower ends of the front plate 3 and the back plate 5 via a fold line 90, respectively.

  A top plate 7 is connected to the upper end of the back plate 5. An insertion piece 71 is connected to the front end (upper end in the figure) of the top plate 7 via a fold line 90.

  Side flaps 21 and 41 are connected to the upper ends of the side plates 2 and 4 via folding lines 90, respectively. Side flaps 22 and 42 are connected to the side plates 2 and 4 via folding lines 90 that are inclined at an inclination angle θ with respect to the sides of the suspension 8. Second bottom plates 62 and 64 are connected to lower ends of the side plates 2 and 4 via folding lines 90, respectively.

  In the drawing of the first bottom plates 63 and 65, adhesive pieces 63a and 65a are connected to the right via a folding portion 95 composed of a folding line 90 inclined by about 45 ° with respect to the bottom of the front plate 3. The

  In the blank plate 100 of FIG. 5, the side plates 2, 4 are bent toward the inner surface side of the front plate 3 at a fold line 90. Then, the back plate 5 is bent at the fold line 90 toward the inner surface side of the side plate 4, and the glue margin piece 55 is bent at the fold line 90 toward the inner surface side of the back plate 5.

  And the outer surface of the glue margin piece 55 is adhere | attached on the inner surface of the rear-end part (right end part in FIG. 5) of the side plate 2 with an adhesive agent. Thereby, the cylindrical trunk | drum 10 is formed.

  Further, the second bottom plate 62 and the adhesive piece 63a are bonded together with an adhesive or the like in the adhesive regions A1 and B1. Similarly, the 2nd bottom face board 64 and the adhesive piece 65a are bonded together with an adhesive etc. in the adhesion | attachment area | region A2, B2.

  And the trunk | drum 10 is crushed flat by bending of the folding parts 93 and 94. FIG. At this time, the side plate 2 and the front plate 3 face each other, and the side plate 4 and the back plate 5 face each other.

  FIG. 6 shows a front view of the hanging packaging box 1 in which the body portion 10 is flattened. FIG. 7 shows a bottom view of the hanging packaging box 1 in which the body portion 10 is flattened. The inner surfaces of the side plates 2 and 4 are close to the inner surfaces of the front plate 3 and the back plate 5, respectively. At this time, the first bottom plates 63 and 65 are separated from each other. That is, the engagement of the first bottom plates 63 and 65 is released. Further, the folding portion 95 is bent toward the inside of the trunk portion 10, and the adhesive pieces 63 a and 65 a are arranged so as to overlap the first side plates 63 and 65, respectively.

  The suspended packaging box 1 is transported and stored in a flat state (folded body) that is crushed flat. Thereby, the transportation cost and storage cost of the hanging packaging box 1 can be reduced.

  From the state of FIG. 6, the folding parts 93 and 94 are pressed with fingers in a direction approaching each other. Thereby, the trunk | drum 10 is raised so that the side plates 2 and 4 may become substantially perpendicular | vertical with respect to the front plate 3 and the back plate 5. FIG.

  FIG. 8 is a perspective view showing a state in which the bottom surface portion 6 is formed when the hanging packaging box 1 is assembled from the state of FIG. 6 in which the body portion 10 is flattened. As described above, when the folding portion 93 is pushed toward the folding portion 94 to raise the trunk portion 10, the folding portion 95 that is bent toward the inside of the trunk portion 10 is folded back, and the first bottom plates 63 and 65 are returned. Engage with each other to form the bottom surface portion 6. At this time, the tip of the first bottom plate 65 is disposed on the inner surface side of the first bottom plate 63 and the second bottom plate 62. Further, the front end portion of the first bottom plate 63 is disposed on the inner surface side of the first bottom plate 65 and the second bottom plate 64.

  As described above, the bottom surface portion 6 is also formed at the same time as raising the body portion 10 crushed flat. That is, the hanging packaging box 1 has a so-called auto bottom structure. Thereby, the trunk | drum 10 with which the opening surface 10b was closed in the place which accommodates the content in the trunk | drum 10 can be assembled easily. And in the trunk | drum 10 which formed the bottom face part 6, the content is accommodated through opening surface 10a, 10c. At this time, since the opening surface 10c facing the front surface side is formed in addition to the opening surface 10a on the upper surface, the contents can be easily stored in the body portion 10, and workability can be improved.

  Thereafter, the side flaps 21, 22, 41, 42 are bent toward the inside of the body portion 10. The side flaps 22 and 42 are bent along inclined portions 25 and 45 that are inclined with respect to the front plate 3 at an inclination angle θ (see FIGS. 5 and 6). The suspended portion 8 is disposed along the inclined portions 25 and 45 in contact with the side surface flaps 22 and 42. Thereby, the suspension part 8 will be in the state inclined with respect to the front plate 3, and closes the opening surface 10c. At this time, the top surface flap 83 is bent backward by the first bent portion 91. Thereby, as shown in FIG. 9, the top surface flap 83 is disposed on the side surface flaps 21 and 41.

  The top surface flap 83 is positioned substantially horizontally on the opening surface 10 a by the side surface flaps 21 and 41, and the top surface flap 83 is prevented from falling into the body portion 10. Therefore, workability at the time of assembling the hanging packaging box 1 can be improved.

  Thereafter, the top plate 7 is folded on the top flap 83 along the fold line 90 from the state of FIG. 9, and the insertion piece 71 is folded along the fold line 90 toward the inner surface side of the top plate 7. Then, the insertion piece 71 is inserted into the slit 86. Thereby, the top plate 7 closes the opening surface 10a above the trunk portion 10, and the suspended packaging box 1 containing the contents is formed.

  At this time, since the top plate 7 is engaged with the suspending portion 8, the suspending portion 8 can maintain an inclined state with respect to the front plate 3. In addition, the top surface flap 83 disposed on the side surface flaps 21 and 41 prevents the top surface plate 7 from falling into the body portion 10.

  The suspended packaging box 1 containing the contents is suspended by inserting a rod-shaped member 200 (see FIG. 1) installed in the store through the through hole 87 of the suspended portion 8. At this time, the suspending portion 8 provided continuously with the front plate 3 is inclined along the inclined portions 25 and 45 of the side plates 2 and 4, and the top plate 7 is inserted into the slit 86 on the back side of the suspending portion 8. The insertion piece 71 is inserted.

  Thereby, the center of gravity of the hanging packaging box 1 storing the contents and the position (fulcrum) of the through-hole 87 in contact with the rod-shaped member 200 can be substantially matched in the front-rear direction. Therefore, when the suspended packaging box 1 is suspended from the rod-shaped member 200, the forward and backward tilting of the suspended packaging box 1 can be prevented, and the front plate 3 can be disposed substantially vertically. As a result, the appeal surface formed on the front surface of the front plate 3 and the front surface of the hanging portion 8 can be easily seen, and the advertising effect of the product can be improved.

  Moreover, it is not necessary to insert the suspending portion 8 into the top plate 7, and the top plate 7 bent from the back plate 5 can be engaged and closed with the slit 86 on the back side of the inclined suspending portion 8. Therefore, the assembly man-hour of the hanging packaging box 1 can be reduced.

  Further, since the slit 86 is formed by bending the top surface flap 83 at the first bent portion 91, the opening surface of the slit 86 becomes horizontal. Thereby, the insertion piece 71 can be easily inserted into the slit 86. Therefore, the workability in assembling the hanging packaging box 1 can be improved, and the number of assembling steps can be further reduced.

  A top surface flap 83 is disposed between the front end (tip) of the top surface plate 7 and the opening surface 10 a above the trunk portion 10. Thereby, the tampering of the contents through the gap between the front end of the top plate 7 and the hanging portion 8 can be prevented.

  Further, when the insertion piece 71 inserted into the slit 86 is pulled upward, the protrusion 71 b is locked to the left and right ends of the slit 86. If the insertion piece 71 is further pulled upward in this state, the suspended portion 8 at the peripheral edge of the slit 86 is broken or the insertion piece 71 is broken. Therefore, since the opened trace remains on the top plate 7, tampering of the contents through the top plate 7 can be further prevented.

  When a customer or the like who has purchased a product whose contents are stored in the hanging packaging box 1 grasps the gripping portion 51b and breaks the back plate 5 along the perforation 51a, the lid portion 51 opens, and the hanging packaging box 1 is opened. Thereby, the contents can be easily taken out from the hanging packaging box 1. Then, the body portion 10 of the hanging packaging box 1 from which the contents are taken out is folded at the folding portions 93 and 94 as shown in FIG. 6 and crushed flat to reduce the volume of garbage. Can do.

  In addition, it is preferable to form the hanging packaging box 1 by changing the inclination angle θ according to the contents stored in the body portion 10.

  For example, the distance D1 between the upper end of the front plate 3 and the upper end of the through hole 87 of the hanging packaging box 1 is 56.5 mm, the distance D2 between the side plates 2 and 4 in the front-rear direction is 60 mm, and the upper end and side plate of the front plate 3 A distance D3 between the upper ends of 2 and 4 is formed to be 24 mm.

  At this time, when the center of gravity of the hanging packaging box 1 containing the contents is located at the approximate center of the body portion 10 in the front-rear direction, the inclination angle θ is set to 32 °. Thereby, the position of the through hole 87 in the front-rear direction substantially coincides with the center of gravity of the hanging packaging box 1.

  In addition, when the center of gravity of the hanging packaging box 1 containing the contents is located approximately 10 mm ahead of the center of the trunk portion 10 in the front-rear direction, the inclination angle θ is set to 21 °. Thereby, the position of the through hole 87 in the front-rear direction substantially coincides with the center of gravity of the hanging packaging box 1.

  In addition, when the center of gravity of the hanging packaging box 1 containing the contents is located about 10 mm behind the center of the body portion 10 in the front-rear direction, the inclination angle θ is set to 45 °. Thereby, the position of the through hole 87 in the front-rear direction substantially coincides with the center of gravity of the hanging packaging box 1.

  When the inclination angle θ is smaller than 15 °, the side surface flaps 22 and 42 (second side surface flaps) become too small, and the side surface flaps 22 and 42 are difficult to be bent at the fold line 90. For this reason, when the inclination angle θ is set to 15 ° or more, the side surface flaps 22 and 42 can be easily folded at the folding line 90.

  On the other hand, when the inclination angle θ is larger than 50 °, the top plate 7 and the upper part of the suspension part 8 are likely to interfere with each other when the insertion piece 71 is inserted into the slit 86. For this reason, when the inclination angle θ is set to 50 ° or less, the insertion piece 71 can be easily inserted into the slit 86 while preventing interference between the top plate 7 and the upper portion of the suspension portion 8.

  According to the present embodiment, the suspending portion 8 having the through hole 87 is connected to the upper end of the front plate 3 and is inclined along the inclined portions 25 and 45 of the side plates 2 and 4. The insertion piece 71 of the top plate 7 is engaged with a slit 86 (engagement portion) provided on the back surface side of 8.
