By reducing the angle between the front surface portion 210 and the side surface portion 230 and reducing the angle between the side surface portion 220 and the back surface portion 240, the product can be folded flat as shown in FIG. By folding the packaging box P, the angle (first angle) α11 between the front portion 10 and the side surface portion 30 in the inner box portion A becomes the angle (that is, 90 degrees) between the front surface portion 10 and the side surface portion 30 in the assembled state. It is smaller than (may be approximately 90 degrees)), and the angle (second angle) α12 between the back surface portion 40 and the side surface portion 20 in the inner box portion A is the angle between the back surface portion 40 and the side surface portion 20 in the assembled state (that is, that is). , 90 degrees (may be approximately 90 degrees)), and when the packaging box P is folded flat and the right bottom surface 70 is in contact with the side surface 20, the right bottom surface 70 becomes a flat plate. When the main body portion 82 is in contact with the side surface portion 30, the region including the main body portion 82 and the upright portion 88 has a flat plate shape.

At the stage when the packaging box P is manufactured as described above, since the adhesive portion 78 and the main body portion 72 are connected via the cut line 78K, the right bottom surface portion 70 is maintained in a flat state. As a result, the packaging box P is maintained in a flatly folded state, so that space can be saved when storing and transporting the folded packaging box P.

Next, when using the packaging box P, the packaging box P is assembled. That is, the front portion 210 and the back portion 240 in the outer box portion B are parallel to each other, the side surface portion 220 and the side surface portion 230 are parallel to each other, and the front portion 10 and the back surface portion in the inner box portion A are parallel to each other. The packaging box P is three-dimensional by making the side surface portion 20 and the side surface portion 30 parallel to each other and the bottom surface portion 50 perpendicular to the sleeve-shaped portions 5 and 205 so that the 40 is parallel to each other and the side surface portion 20 and the side surface portion 30 are parallel to each other. Assembled into a shape.

The front surface portion 10 and the back surface portion 40 of the inner box portion A are parallel to each other, and the side surface portion 20 and the side surface portion 30 are parallel to each other, so that the bottom surface portion 50 is assembled as follows. ..

That is, the sleeve-shaped portion 5 is widened (that is, the angle between the side surface portion 20 and the back surface portion 40 (second angle) is increased, and the angle between the side surface portion 30 and the front surface portion 10 (first angle) is increased. Then, since the adhesive portion 78 is adhered to the rear bottom surface portion 90, the cut line 78K is broken, the adhesive portion 78 is in a bent state with respect to the upright portion 76, and the main body portion 72 is upright. It is in a bent state with respect to the part 74. That is, in the state where the inner box portion A is folded, the upright portions 74 and 76 are originally oriented in the vertical direction, and by increasing the angle between the side surface portion 20 and the back surface portion 40, the main body portion 72 becomes the side surface portion 20. On the other hand, the rear bottom surface portion 90 rotates downward with respect to the back surface portion 40, but the standing portions 74 and 76 remain oriented in the vertical direction, so that the rear bottom surface portion 90 is adhered to the rear bottom surface portion 90. The adhesive portion 78 is in a bent state with respect to the upright portion 76, and the main body portion 72 is in a bent state with respect to the upright portion 74. That is, in the relationship between the upright portion 76 and the adhesive portion 78, the upright portion 76 is in a state of being bent upward with respect to the adhesive portion 78, and in the relationship between the upright portion 74 and the main body portion 72, the upright portion 74 is the main body portion. It is in a state of being bent upward with respect to 72 (see FIG. 15). Further, as the sleeve-shaped portion 5 is expanded, the main body portion 72 and the rear bottom surface portion 90 that are opposed to each other are separated from each other, so that the cut line 78K is broken.

After that, when the sleeve-shaped portion 5 is further expanded, the upright portion 88 comes into contact with the upright portion 74, and the upright portion 88 comes into contact with the upright portion 74, so that the upright portion 88 rotates upward with respect to the main body portion 82. I will do it. Immediately before the standing portion 88 comes into contact with the standing portion 74, the side portion 88c of the standing portion 88 (the upper side when the standing portion 88 stands up) is in contact with the side portion 72d of the main body portion 72 of the right bottom surface portion 70. The upright portion 88 approaches the upright portion 74, and the side portion 88c of the upright portion 88 touches the corner portion 75 (the corner portion along the polygonal line C25) between the upright portion 74 and the upright portion 76.

After the side portion 88c is in contact with the corner portion 75 between the upright portion 74 and the upright portion 76, when the sleeve-shaped portion 5 is expanded, the side portion 88c is in contact with the corner portion 75 and in contact with the side portion 72d. Then, while the standing portion 88 rotates with respect to the main body portion 82, the standing portion 88 slides to the back side with respect to the standing portion 74, and the position of the side portion 88c in contact with the side portion 72d is the side portion 88c. When it comes to the end on the front side, the side portion 88d (the side portion on the front side) of the standing portion 88 comes into contact with the side portion 72d.

After that, when the sleeve-shaped portion 5 is further expanded, the standing portion 88 is on the back side with respect to the standing portion 74 in a state where the side portion 88c is in contact with the corner portion 75 and the side portion 88d is in contact with the side portion 72d. The standing portion 88 rotates with respect to the main body portion 82 while sliding to.

Then, with the side portion 88c in contact with the corner portion 75 and the side portion 88d in contact with the side portion 72d, the side portion 82f (inclined side portion) of the protruding portion 84 is in contact with the corner portion 75, and the side portion 88c With the side portion 82f in contact with the corner portion 75 and the side portion 88d in contact with the side portion 72d, the upright portion 88 slides to the back side with respect to the upright portion 74 while the upright portion 88 with respect to the main body portion 82. The end of the side 82f on the side 82g side comes to the position of the corner 75, and the side 88d comes to the end of the side 72d on the side 72e side. The side portion 82g of the 84 engages with the corner portion 75 (which may be the end portion on the left side surface side of the standing portion 76), and the side portion 88d of the standing portion 88 (the end portion on the front side of the standing portion 88) is the main body. The bottom surface portion 50 is assembled by engaging with the side portion (engagement side portion) 72e of the portion 72, and the inner box portion A is in the assembled state. The timing at which the side portion 82f engages with the upright portion 76 and the timing at which the side portion 88d of the upright portion 88 engages with the side portion 72e of the main body portion 72 are simultaneous (may be substantially simultaneous). The assembled state of the bottom surface portion 50 is shown in FIGS. 16 and 17.

In addition, in FIG. 15 and FIG. 16, in order to make it easy to understand the state of the inner box portion A, the configuration of the outer box portion B is omitted and only the inner box portion A is shown. Further, in FIG. 17, in order to make it easy to understand the state in which the inner box portion A is assembled in a three-dimensional shape and the bottom surface portion 50 is assembled, the adhesive by the glue margin portion 49 is released, and the front front portion 11 and the side surface portion are shown. It is explanatory drawing by the perspective which shows the state that 20 is on the same plane.

In the state where the bottom surface portion 50 is assembled, the standing portion 88 is bent at a substantially perpendicular angle (may be a right angle) to the main body portion 82 and stands up, and the standing portion 74 is substantially perpendicular (perpendicular) to the main body portion 72. The standing portion 76 is bent at a substantially right angle (may be a right angle) to the adhesive portion 78 and stands up, and the standing portion 76 is substantially perpendicular to the standing portion 74. It is bent (may be at right angles), and the surface of the upright portion 88 on the upright portion 74 side and the surface of the upright portion 74 on the upright portion 88 side face each other (that is, the two surfaces face each other) and stand up. At least a part of the surface of the portion 88 on the upright portion 74 side and the surface of the upright portion 74 on the upright portion 88 side are in contact with each other.

After the packaging box P is assembled in a three-dimensional shape, the inclined portion 14 is in a state of being rotated with respect to the rear front portion 12, and the supporting portion 16 is rotated with respect to the inclined portion 14 so that the supporting portion 16 faces in the vertical direction. The support portion 16 is in contact with the inner surface of the back surface portion 40, and the legs 18-1 and 18-2 are in contact with the upper surface of the rear bottom surface portion 90. Then, the inclined portion 14 is in contact with the standing portions 74, 76, 88 and is in a state of being inclined with respect to the horizontal direction (front bottom surface portion 60, main body portions 72, 82, rear bottom surface portion 90). Depending on the degree of upward protrusion of the upright portion 74, the upright portion 76, and the upright portion 88 when the bottom surface portion 50 is assembled, the bottom surface of the inclined portion 14 may not come into contact with all of the upright portions 74, 76, 88. In some cases, the bottom surface of the inclined portion 14 is in contact with at least one of the standing portions 74, 76, 88. Even if all of the standing portions 74, 76, and 88 do not come into contact with each other, the standing portion 88 extends longer in the front-rear direction than the standing portion 74, and it is the standing portion 76 that extends in the left-right direction. It can be said that the portion 14 is in contact with at least the standing portion 88 and the standing portion 76.

When the inclined portion 14 is in contact with the standing portions 74, 76, 88, a virtual plane surrounded by the lower side of the sleeve-shaped portion 5 (the lower side of the front front portion 11, the lower side of the side surface portions 20, 30 and the lower side of the back surface portion 40). It is in an inclined state through (may be the installation surface of the inner box portion A).

When the sleeve-shaped portion 5 is expanded and the inner box portion A is assembled (that is, the inner box portion A is assembled), the inclined portion 14 folded back with respect to the rear front portion 12 is before being folded back. Since it naturally rotates to the back side in an attempt to return to the state, by grasping the connecting portion 17 with a finger and pushing it downward, the side portion 14a on the left side surface side of the inclined portion 14 becomes the glue margin portion 49. In contact with each other, the friction between the side portion 14a and the glue margin portion 49 can maintain a state in which at least the upper side of the support portion 16 is in contact with the inner surface of the back surface portion 40, and the inclined portion 14 rises upward from the inclined state. Can be prevented. In the state where the product is not placed on the inclined portion 14, even if the inclined portion 14 does not touch the standing portions 74, 76 and 88 and the legs 18-1 and 18-2 do not contact the rear bottom surface portion 90. By placing the product on the inclined portion 14, the inclined portion 14 comes into contact with the standing portions 74, 76, 88 and the legs 18-1, 18-2 come into contact with the rear bottom surface portion 90 due to the weight thereof.

Then, as shown in FIG. 18, a plurality of products (objects to be stored) G are stored in the inner box portion A from above the packaging box P. FIG. 18 shows an example of a bag-shaped product, but other products may be used. Since the lid portion 270, 280 and the flap portion 260, 290 are in a state of being erected upward in advance and the upper part of the outer box portion B is in an open state, the product G remains as it is in the packaging box P. It can be stored from above. Then, after closing the flap portions 260 and 290, the lid portions 270 and 280 are closed, and as shown in FIG. 19, the adhesive tape T is adhered from the front portion 210 of the outer box portion B to the back portion 240 side via the upper surface. The lid portion 270 and 280 are sealed.

After the product G is packaged in the packaging box P as described above, the packaging box P containing the product G is transported to the place where the product G is displayed.

After that, when displaying the products, the outer box portion B is separated from the inner box portion A. That is, after making it possible to hook a finger on the tip of the piece 224 by pushing the piece 226 of the side surface 220 of the outer box part B inward, the piece 224 is rotated outward to show FIG. The state shown in. That is, the polygonal line C224 serves as a rotation axis, and the piece 224 rotates in the vertical direction.

Similarly, the piece 234 of the side surface 230 of the outer box B is pushed inward so that a finger can be hooked on the tip of the piece 234, and then the piece 234 is rotated outward. That is, the polygonal line C234 serves as a rotation axis, and the piece 234 rotates in the vertical direction. It should be noted that, even if a ruled line is not formed at the points of the polygonal lines C224 and C234 that serve as the rotation axis when the one part 224 and 234 rotate, the polygonal line is naturally formed by rotating the one part 224 and 234. However, a ruled line may be formed in advance at the location of the polygonal line.

Then, when the piece 224 of the outer box portion B is rotated outward, the cut line 24a around the separation portion 24 is broken at the same time, and the separation portion 24 becomes the inner box portion A (specifically, the main body portion). Separated from 22) and adhered to the rotated piece 224, the piece 224 is driven. Similarly, when the piece 234 of the outer box portion B is rotated outward, the cut line 34a around the separation portion 34 is broken at the same time, and the separation portion 34 becomes the inner box portion A (specifically, the main body). Separated from the part 32) and adhered to the rotated piece 234, the piece 234 is driven.

Then, as shown in FIG. 21, by pulling up the outer box portion B upward, the inner box portion A in the state where the product G is stored and the separated portions 24 and 34 are separated remains. The inner box part A is displayed in a state where the items are stored. In the inner box portion A of the packaging box P, since the notch portion K10 is profitable in the front portion 10, the product G is visually recognized from the front side by displaying the front portion 10 side as the front side in the display. be able to. That is, the product G can be visually recognized from above the inner box portion A, and can be visually recognized from the front portion 10 side of the inner box portion A.

In the assembled state of the inner box portion A, the product G is placed on the upper surface of the inclined portion 14, and the inclined portion 14 is inclined so as to be downward toward the front portion 10 side. The product G is displayed in an inclined state and can be easily slid to the front portion 10 side, the product G can be easily taken out from the front side, and it is not necessary to perform the work of moving the product to the front side. That is, when the product in the foreground is taken out, the product G placed on the inclined portion 14 slides toward the front portion 10 due to the weight of the product G, so that the product G can always be positioned on the front side.

Further, since the bottom surface of the inclined portion 14 is supported by the standing portions 74, 76, 88 to maintain the inclined state of the inclined portion 14, the inclined portion 14 is formed long in the inclined direction, or a heavy product is placed on the inclined portion 14. Even in this case, the product can be displayed in an inclined state without the inclined portion 14 bending downward. In particular, since the standing portions 74 and 88 extend in the front-rear direction to stand up and the standing portions 76 extend in the left-right direction to stand up, the inclined state of the inclined portion 14 is stably maintained. Further, since the inclined portion 14 is also supported by the supporting portion 16, the inclined portion 14 can be maintained in the inclined state by the supporting portion 16, and in particular, the region of the inclined portion 14 on the back side of the standing portion 88 is formed. Does not bend downward.

Further, when the inclined portion 14 is supported by the standing portions 74, 76, 88, the side portion 74c of the standing portion 74 and the side portion 88c of the standing portion 88 are in a state along the bottom surface of the inclined portion 14. The inclined state of the inclined portion 14 can be stabilized. In the state where the bottom surface portion 50 is assembled, the standing portion 76 faces in the left-right direction, so that there is no problem in supporting the inclined inclined portion 14.

Further, the support portion 16 is provided with the connecting portion 17, and in the inclined state of the inclined portion 14, the connecting portion 17 is in a state of being erected from the end portion on the back surface side of the inclined portion 14 (see FIG. 4). , There is no possibility that the product placed on the inclined portion 14 will fall from the back surface portion 40 side of the inclined portion 14. That is, in the case of a product having a thin thickness in the front-rear direction, if the connecting portion 17 is not provided, the product may fall from the end portion of the inclined portion 14 on the back surface portion 40 side into the gap between the inclined portion 14 and the back surface portion 40. Since the connecting portion 17 is provided, there is no risk of this.

Further, according to the above description of the first embodiment, it is assumed that the rear front portion 12 is continuously provided from the front front portion 11 and the inclined portion 14 is continuously provided from the rear front portion 12, but the rear front portion 12 and the rear front portion 12 are connected. A configuration including the inclined portion 14 and the support portion 16 may be continuously provided from the upper side of the back surface portion 40. That is, the back surface portion 40 is configured to have a notch formed like the front front surface portion 11, and the rear back surface portion having the same configuration as the rear front surface portion 12 is continuously provided from the upper side of the back surface portion 40, and further, the rear back surface portion is further provided. The inclined portion 14 is continuously provided from the side portion opposite to the back surface portion 40 of the above, and further, the supporting portion 16 is continuously provided from the inclined portion 14. The rear front surface portion 12 is not formed in the front surface portion 10, and the notch portion is not formed in the front front surface portion 11.

In this case, since the inclined portion is inclined upward from the back side to the front side, the side portion 74c in the standing portion 74 and the side portion 88c in the standing portion 88 are directed from the back side to the front side. Tilt to the upper side (that is, the tilt direction is reversed). The upright portion 88 is provided with a notch for the protruding portion 84, and if the inclination direction of the side portion 74c is reversed, the side portion 74c and the notch portion may interfere with each other. May be provided only on the front side of the protruding portion 84.

The packaging box P'of the second embodiment has substantially the same configuration as the packaging box P of the first embodiment, and only the configuration of the inner box portion is different.

That is, the inner box portion A'in the packaging box of the second embodiment is configured as shown in FIGS. 22 to 24, and instead of forming the notch portion on the front portion 10, the notch portion K40 is provided on the upper side of the back surface portion 40. It is formed.

That is, the back surface portion 40 has a shape in which the notch portion K40 is provided on the upper side of the square shape, and the upper side portion of the back surface portion 40 is continuously provided from the upper side of the side surface portion 20 and is formed linearly in the left-right direction. A straight line formed from the edge 40a and the end of the side 40a and formed in a substantially arcuate linear shape, and a straight line formed from the end of the side 40b in a substantially vertical direction. A side portion 40c having a shape and a side portion 40d connected from the end portion of the side portion 40c and formed in a substantially arc shape, and a side portion 40d connected from the end portion of the side portion 40d, formed linearly in the left-right direction. A side portion 40e and a side portion 40f connected from the end portion of the side portion 40e and formed in a substantially arc shape, and a side portion connected from the end portion of the side portion 40f and formed substantially linearly in the vertical direction. A side portion 40i connected from the end portion of the portion 40g and the side portion 40g and formed in a substantially arc shape, and a side portion 40i connected from the end portion of the side portion 40h and formed linearly in the left-right direction. And have. The side portion 40a and the side portion 40i are formed in the same linear shape, the side portion 40c is inclined with respect to the direction of the polygonal lines C3 and C4 so as to be on the left side surface side as it goes downward, and the side portion 40g is downward. It is inclined with respect to the direction of the polygonal lines C3 and C4 so as to be on the right side as it goes toward. The side portion 40c and the side portion 40g are tapered.

In the second embodiment, notches are not formed in the front front portion 11 and the rear front portion 12.

Since the configuration of the inner box portion A'is the same as that of the inner box portion A of the first embodiment except for the above points, detailed description thereof will be omitted.

Further, since the outer box portion B in the packaging box P'of the second embodiment has the same configuration as the outer box portion B in the first embodiment, detailed description thereof will be omitted.

Further, the method of manufacturing the packaging box of Example 2 is the same as that of the packaging box of Example 1 except that the inner box portion A'is used as the inner box portion, and thus detailed description thereof will be omitted.

In the inner box portion A'of the second embodiment, since the cutout portion K40 is provided on the back surface portion 40, the back surface portion 40 is used as the front side in the display when displaying the products. That is, the perspective view of the inner box portion A'viewed from the front side in the display is as shown in FIG. 23, and the perspective view of the inner box portion A'viewed from the back side in the display is as shown in FIG. 24.

Then, in the state where the products are displayed, the inclined portion 14 is in a state of being inclined downward from the front side to the back side in the display, so that the front side of the displayed products is obliquely upward, so that the front side of the products It is possible to make it easier to see the surface of the product from diagonally above.

The usage state of the packaging box of the second embodiment is the same as that of the packaging box of the first embodiment except that the back surface 40 side is used as the front side of the display at the time of display, so detailed description thereof will be omitted.

In the second embodiment, if the product is taken out from the front side of the display, the product does not need to slide on the upper surface of the inclined portion 14, so that the weight of the product is heavy and the bottom surface of the product is difficult to slide. When the product is difficult to slide on the inclined portion 14, it is preferable to use the inner box portion A'of Example 2, while the weight of the product is light and the bottom surface of the product is easy to slide. When the product, which is made of a material, easily slides on the inclined portion 14, it can be said that it is preferable to use the inner box portion A of the first embodiment.

Further, also in the packaging box P'of the second embodiment, the inclined portion 14 is supported not only by the supporting portion 16 but also by the standing portions 74, 76, 88, so that the inclined portion 14 is long in the inclined direction. Even when a product is formed or a heavy product is placed on the product, the product can be displayed in an inclined state without the inclined portion 14 bending downward. In particular, since the standing portions 74 and 88 extend in the front-rear direction to stand up and the standing portions 76 extend in the left-right direction to stand up, the inclined state of the inclined portion 14 is stably maintained.

Further, also in the packaging box P'of the second embodiment, when the inclined portion 14 is supported by the upright portions 74, 76, 88, the side portion 74c of the upright portion 74 and the side portion 88c of the upright portion 88 are inclined portions. Since the state is along the bottom surface of 14, the inclined state of the inclined portion 14 can be stabilized. In the state where the bottom surface portion 50 is assembled, the standing portion 76 faces in the left-right direction, so that there is no problem in supporting the inclined inclined portion 14.

Further, also in the packaging box P'of the second embodiment, the support portion 16 is provided with the connecting portion 17, and when the inclined portion 14 is in an inclined state, the connecting portion 17 is an end portion of the inclined portion 14 on the back surface portion 40 side. Since it is in an upright state (see FIG. 24), there is no possibility that the product placed on the inclined portion 14 will fall from the back surface portion 40 side of the inclined portion 14.

In Example 2, an opening may be used instead of the notch K40. That is, the height of the sleeve-shaped portion 5 in the vertical direction is made higher than the configuration shown in the drawing, and an opening is formed in the back surface portion 40 so that the product can be visually recognized and the product can be taken out from the opening. You may.

Further, according to the above description of the second embodiment, it is assumed that the rear front portion 12 is continuously provided from the front front portion 11 and the inclined portion 14 is continuously provided from the rear front portion 12, but the rear front portion 12 and the rear front portion 12 are connected. A configuration including the inclined portion 14 and the support portion 16 may be continuously provided from the upper side of the back surface portion 40. That is, the back surface portion 40 has a configuration in which the notch portion K40 is omitted, and the rear back surface portion having the same configuration as the rear front surface portion 12 is continuously provided from the upper side of the back surface portion 40. An inclined portion 14 is continuously provided from the side portion on the opposite side, and a support portion 16 is continuously provided from the inclined portion 14. In the front portion 10, the rear front portion 12 is not formed, and the front front portion 11 is formed with a notch portion similar to the notch portion K40.

In this case, since the inclined portion is inclined upward from the back side to the front side, the side portion 74c in the standing portion 74 and the side portion 88c in the standing portion 88 are directed from the back side to the front side. Tilt to the upper side (that is, the tilt direction is reversed). The upright portion 88 is provided with a notch for the protruding portion 84, and if the inclination direction of the side portion 74c is reversed, the side portion 74c and the notch portion may interfere with each other. May be provided only on the front side of the protruding portion 84.

According to the packaging boxes of Examples 1 and 2, the product to be stored is stored from above in the packaging box having an opening at the top, and the lids 270 and 280 are closed to provide one adhesive tape. Since it is only sealed with T, the product can be easily packed.

Further, according to the packaging box manufacturing methods of Examples 1 and 2, as described above, the outer box portion B and the inner box portion A (or the inner box portion A') are overlapped and adhered to each other, and then the front surface is fronted. After adhering the portion 11 and the rear front portion 12, each portion constituting the bottom surface portion 50 is folded back with respect to the sleeve-shaped portion 5, the adhesive is applied to a predetermined area, and then the folding step is performed twice (that is,). Since it can be manufactured by the step from the state of FIG. 12 to the state of FIG. 13 and the step from the state of FIG. 13 to the state of FIG. 14), the packaging box can be easily manufactured.

Further, in the outer box portion B, the cut lines 222a, 222c, 232a, and 232c are assumed to be cut lines, but cut lines formed by continuous cuts may be used.

In addition, in Example 1 and Example 2, it was assumed that the cutouts (cutouts K10, K40) for visually recognizing the product from the front side in the display were provided, but the configuration of the cutouts was omitted. May be good. That is, even if the cutout portion is not provided, the products displayed in the inner box portion can be visually recognized from diagonally above, so that the configuration of the cutout portion may be omitted.

Further, in the above description, it has been described that the packaging box is manufactured by the steps shown in FIGS. 10 to 14, but the unfolded state of the outer box portion B and the inner box portion A (or the inner box portion A') is symmetrical. It may be manufactured. That is, taking Example 1 as an example, the inner box portion A in the state shown in FIG. 6 is overlapped and adhered to the upper surface of the outer box portion B in the state shown in FIG. 9, and the front front portion 11 and the rear front portion 12 are attached to each other. After adhering, each part constituting the bottom surface of the inner box portion A is folded back, the adhesive portion 86 is folded outward, an adhesive is applied to the adhesive portion 78, the back surface portion 240 is folded back, and further, the adhesive portion 86 and glue are folded back.
