In the folded state, the flap protrudes from the right side of the upper surface portion 150 (that is, protrudes to the outside of the width in the left-right direction of the main body portion 3), which requires extra space in the folded state. Therefore, the flap is not provided on the right side surface side of the upper surface portion 150. If the flap is provided on the right side of the upper surface portion 150, it is conceivable that the flap is folded back with respect to the upper surface portion in the folded state of the packaging box 1, but the flap is attached to the upper surface portion 150 due to the restoring force of the blank. It is not realistic because it opens to the right side from the folded state.

The main body portion 3 and the sub-body portion 101 are adhered to each other at the separation portion 44. That is, the outer surface of the separation portion 44 and the inner surface of the back surface portion 140 are adhered to each other by an adhesive or other adhesive means, so that the packaging box 1 is integrally formed as a whole. That is, an adhesive layer (not shown) is provided between all or a part of the outer surface of the separation portion 44 and a part of the inner surface of the back surface portion 140. The adhesive force of the adhesive layer is optional because the separation portion 44 is pulled diagonally upward to break the cut line K44 in a state where the hand is locked to the inner surface of the separation portion 44, but the back surface portion 140 Is pulled outward, the cut line K44 is torn and the separation portion 44 is separated from the main body portion 3, and the separation portion 44 has an adhesive force that follows the back surface portion 140 in a state of being adhered to the back surface portion 140. Is preferable.

In the main body portion 3 and the sub-body portion 101, a ruled line is formed in advance at each polygonal line. In particular, in the broken lines C1, C2, C3, C4, C6, C7, C8, and C9, the ruled lines are pressed from the inner surface of the main body 3, and the broken lines C11, C12, C13-1, C13-2, and C13. In -3, it is a ruled line pressed from the inner surface of the sub-body portion 101. Since the polygonal lines 70-1 and 80-1 on the bottom surface portion 50 are mountain-folded when viewed from the upper surface side, it is preferable to use a ruled line pressed from the outer surface.

Further, in the state where the main body portion 3 and the sub-body portion 101 are adhered to each other, the upper sides 40Ta, 40Tb, 40Tc of the back surface portion 40 and the polygonal line C12 are substantially aligned (may be matched) in the height direction. Strictly speaking, the polygonal line C12 is slightly above the upper sides 40Ta, 40Tb, and 40Tc. As a result, when the upper surface of the main body 3 is closed by the upper surface portion 150, the protruding portions 154 and 156 are in contact with the upper side of the side surface portion 20 and the protruding portion 158 is in contact with the upper side of the side surface portion 30. It is possible to prevent the formation of a gap between the upper sides of the side surface portions 20 and 30.

Further, in a state where the main body portion 3 and the sub-body portion 101 are adhered to each other, the lower end of the back surface portion 140 and the lower end of the back surface portion 40 are aligned (may be substantially the same).

The manufacturing process of the packaging box 1 having the above configuration will be described. First, the main body portion 3 and the sub-body portion 101 in the expanded state are manufactured.

Next, the outer surface of the main body portion 3 is adhered to the inner surface of the sub-body portion 101 (first bonding step). That is, with the inner surface of the sub-body portion 101 in the unfolded state facing upward, the adhesive is applied to the adhesive region with the separated portion 44 on the back surface portion 140, and the main body portion 3 in the unfolded state is shown in FIG. Stack. As a result, the separated portion 44 and the back surface portion 140 are bonded (first bonding step). At that time, the lower side of the back surface portion 40 and the lower side of the back surface portion 140 are made to match (may be substantially the same). An adhesive may be applied to the region of the outer surface of the separation portion 44 to adhere the separation portion 44 to the back surface portion 140.

Next, each portion constituting the bottom surface portion 50 of the main body portion 3 is folded inward with respect to the sleeve-shaped portion 5, and further, the tip portion 74 of the second piece portion 70 is folded outward with respect to the main body portion 72, and the second piece is folded. 3 The tip portion 84 of the piece portion 80 is folded outward with respect to the main body portion 82 to obtain the state shown in FIG. 7 (folding step). That is, the first piece portion 60 is folded back to the front portion 10 side via the polygonal line C6, the second piece portion 70 is folded back to the side surface portion 20 side via the polygonal line C7, and the third piece portion 80 is folded back to the side surface portion via the polygonal line C9. The fourth piece 90 is folded back to the back portion 40 side via the polygonal lines C8-1 and C8-2, the tip portion 74 is folded back to the main body portion 72, and the tip portion 84 is folded back to the main body. It is folded back with respect to the portion 82 so as to be in the state shown in FIG.

Next, an adhesive is applied to the region of the tip portion 74 (adhesive application step), and the front portion 10 is folded inward toward the side surface portion 20 via the folding line C1 (second folding step) (FIG. 8), the tip portion 74 is bonded to the first piece portion 60 (second bonding step). Instead of the tip portion 74, an adhesive may be applied to the adhesive region of the first piece portion 60 with the tip portion 74.

Next, an adhesive is applied to the region of the tip portion 84 and the region of the glue margin portion 49 (adhesive application step), and the side surface portion 30 is folded inward toward the back surface portion 40 via the polygonal line C3. , The state shown in FIG. Then, the tip portion 84 and the fourth piece portion 90 are bonded, and the glue margin portion 49 is bonded to the outer surface of the front surface portion 10 (third bonding step). Instead of the glue margin portion 49, an adhesive may be applied to the adhesive region of the front surface portion 10 with the glue margin portion 49, and instead of the tip portion 84, the tip portion 84 of the fourth piece portion 90 may be applied. An adhesive may be applied to the area to be adhered to. As described above, the packaging box 1 is manufactured. The above manufacturing is automatically manufactured by the assembly device. As described above, since the packaging box 1 can be manufactured by the first bonding step to the third bonding step, the packaging box 1 can be easily manufactured. When the glue margin portion 49 is adhered to the inner surface of the front surface portion 10, the side surface portion 30 is folded back with the adhesive applied to the tip portion 84, and then the tip portion 74 and the glue margin portion 49 are attached. The front portion 10 is folded back with the adhesive applied.

When the main body portion 3 and the sub-body portion 101 are adhered to each other, whether or not the relative positions of the main body portion 3 and the sub-body portion 101 are correct can be confirmed by a notch for confirming the alignment. That is, the position in the left-right direction can be confirmed by checking whether the positions of the notch 40f and the notch K140b in the left-right direction match and the positions of the notch 42f and the notch K142b in the left-right direction match. The vertical position can be confirmed by checking whether the vertical positions of the cut K140a and 40c match, and the vertical positions of the side portion 42c of the cut K42 and the cut K142a match.

In the above manufacturing process, the step of folding the third piece portion 80 toward the side surface portion 30, folding the fourth piece portion 90 toward the back surface portion 40, and further folding the tip portion 84 with respect to the main body portion 82 is This is performed after the front portion 10 is folded back toward the side surface portion 20 and the tip portion 74 is adhered to the first piece portion 60, and then before the adhesive is applied to the region of the tip portion 84 and the region of the glue margin portion 49. You may. In that case, in the folding step, the first piece 60 and the second piece 70 are folded back, the tip portion 74 is folded back, and then the adhesive is applied to the tip portion 74.

Further, the adhesive is applied to the tip portion 74 in a state where the second piece portion 70 is folded back and the tip portion 74 is folded back, but the second piece portion 70 is in a state before being folded back with respect to the side surface portion 20. After applying the adhesive to the tip portion 74, the tip portion 74 may be folded back while folding back the second piece portion 70.

Further, the adhesive is applied to the tip portion 84 in a state where the third piece portion 80 is folded back and the tip portion 84 is folded back, but the third piece portion 80 is in a state before being folded back with respect to the side surface portion 30. After applying the adhesive to the tip portion 84, the tip portion 84 may be folded back while folding back the third piece portion 80. The adhesive may be applied to the tip portion 84 after the tip portion 74 and the first piece portion 60 are adhered to each other.

A method of using the packaging box 1 having the above configuration will be described. When the packaging box 1 is not used, the packaging box 1 can be folded into a flat plate shape as shown in FIG. 9, so that the packaging box 1 is folded and stored.

Next, when using the packaging box 1, the packaging box 1 is assembled. That is, the front surface portion 10 and the back surface portion 40 of the main body portion 3 are parallel to each other, the side surface portions 20 and the side surface portions 30 are parallel to each other, and the bottom surface portion 50 is perpendicular to the sleeve-shaped portion 5. By assembling, the packaging box 1 is assembled as shown in FIGS. 1 and 2.

Then, as shown in FIG. 10, the stored object (product) G is stored in the main body portion 3. When the main body 3 is assembled from the state of FIG. 9, as shown in FIGS. 1 and 2, the upper surface portion 150 and the front surface portion 110 are in a state of extending upward and above the main body portion 3. Is in an open state, the stored object G may be stored as it is from above the main body portion 3. If the stored object is soft, there is no problem in inserting the front portion 10 or the side surface portion 20 even if a gap is not provided between the front portion 10 or the side surface portion 20 and the stored object. When the stored object G is a hard object such as a box as shown in FIG. 10, a gap is provided between the front surface portion 10 and the stored object or between the side surface portion 20 and the stored object.

After storing the stored object G, the accessory portion 101 is closed and the stored object is packaged. That is, the upper surface portion 150 is rotated toward the front side, the flap 160 is inserted into the main body portion 3 in a state of being bent with respect to the upper surface portion 150, and the main body is in a state of being bent with respect to the upper surface portion 150. It is inserted into the portion 3 to bring it into the state shown in FIGS. 11, 12, and 13. That is, the flap 160 is set to be inside the side surface portion 20, and the front surface portion 110 is set to be inside the front surface portion 10, so that the upper surface side of the main body portion 3 is closed by the upper surface portion 150.

When the sub-body portion 101 is closed, the tip end (side portion 110c) of the front portion 110 is in contact with the upper surface of the bottom surface portion 50 (specifically, the first piece portion 60) (that is, the front portion). The tip of the front portion 110 is in contact with the upper surface of the bottom surface portion 50 while the 110 is parallel to the front surface portion 10 (may be substantially parallel) and is along the inner surface of the front surface portion 10), and the upper surface portion 150 is the main body portion 3. The lower surface of the protruding portions 154 and 156 is in contact with the upper side of the side surface portion 20, and the lower surface of the protruding portion 158 is in contact with the upper side of the side surface portion 30.

After the packaged object G is packaged in the packaging box 1 as described above, the packaging box 1 is transported to the place where the packaged object G is displayed.

After that, when displaying the stored items, the cut line K44 is broken, the sub-body portion 101 is separated from the main body portion 3, and the sub-body portion 101 is removed.

That is, a finger (specifically, a finger other than the thumb (for example, four fingers from the index finger to the little finger)) is inserted into the opening 93 provided on the bottom surface of the packaging box 1, and the inner surface of the separation portion 44 is formed. By hooking a finger on the lower end region (see FIG. 14) and pulling the separation portion 44 outward, the cut line K44 breaks upward from the lower end, and the back surface portion 140 rotates via the break line C12 (FIG. 14). 15). Further, when the back surface portion 140 is lifted upward, the state shown in FIG. 16 is obtained. In FIG. 16, the stored object G is represented by a virtual line in order to show the state of the front portion 110.

Then, by pulling out the front portion 110 from the main body portion 3 and removing the sub-body portion 101 (strictly speaking, the sub-body portion 101 to which the separation portion 44 is adhered), the state shown in FIGS. 17 and 18 is obtained, and the front surface is obtained. The stored object G is displayed with the side of the unit 10 as the front side in the display. The displayed object G can be visually recognized from above and also from the front side through the notch K10.

When the cut line K44 is broken, the back surface 140 is held by the outer surface of the back portion 140 with the thumb, and the back portion 140 is rotated upward to break the cut line K44. As shown in the above, the subbody portion 101 can be removed by lifting the back portion 140 upward and pulling out the front portion 110 with the hand holding the back portion 140, so that the cut line K44 is broken by one series of operations. And the sub-body portion 101 can be taken out.

As described above, according to the packaging box 1 of the present embodiment, since it is only necessary to break the cut line K44 and separate only the separation portion 44, the work of removing the accessory portion 101 (a part of the packaging box 1) is performed. It can be easily performed, and the display work of the stored items can be easily performed. In particular, the separation portion 44 is separated by breaking the cut line K44 and the sub-body portion 101 is taken out in a series of operations. Therefore, the display work of the items to be stored can be easily performed.

Since the cut line K44 is broken by pulling the lower end of the separation portion 44 outward with the finger locked to the lower end of the separation portion 44, the cut line K44 can be easily broken.

When the sub-body portion 101 is closed, the tip end (side portion 110c) of the front surface portion 110 is in contact with the upper surface of the bottom surface portion 50 (specifically, the first piece portion 60), and the upper surface portion 150 is the main body portion. Since the upper surface of the protruding portion 154 is covered, the lower surface of the protruding portions 154 and 156 is on the upper side of the upper side of the side surface portion 20, and the lower surface of the protruding portion 158 is on the upper side of the upper side of the side surface portion 30, the sub-body portion 101 The strength of the packaging box 1 in the closed state can be maintained high, and for example, even if a force is applied to the upper surface portion 150 from above, the upper surface portion 150 can be prevented from sinking downward.

Further, since the main body portion 3 and the sub-body portion 101 have a substantially rectangular shape in the unfolded state, the area of the blank can be effectively utilized. That is, when two packaging boxes 1 of this embodiment are formed from sheet-shaped blanks, the area of the region R1 may be sufficient as shown in FIG.

On the other hand, if it is attempted to form two packaging boxes 1001 that are similar to the one in which the main body portion 3 and the sub-body portion 101 are integrated with one blank, the configuration shown in FIG. 20 is obtained, and the area of the region R11 is required. Since the two regions shown in the hatching in FIG. 20 are wasted, the area of the region R1 can be made smaller than the area of the region R11.

In the packaging box 1001 shown in FIG. 20, an upper surface portion 150 is continuously provided from the back surface portion 40'to the cut line K40', and the back surface portion 40'has a separated portion unlike the packaging box 1. Not provided. When displaying the items to be stored, the cut line K40'is broken to remove the upper surface portion 150, the front portion 110, and the flap 160. In this packaging box 1001, the back surface portion 40'and the upper surface portion 150 are connected to each other by the cut line K40', so that the cut line K40'is easily broken when a force is applied to the upper surface portion 150 from above. It can be said that the strength is weaker than that of the packaging box 1 of this embodiment. That is, in the packaging box 1 of the present embodiment, although the back surface portion 40 and the back surface portion 140 overlap each other, the main body portion 3 and the sub-body portion 101 both exhibit a substantially rectangular shape, so that the blank area is effective. It can be utilized, and further, since there is no cut line along the side portion of the upper surface portion 150, it can be said that the strength can be increased.

In the above description, the flap 160 is connected from the left side surface side of the upper surface portion 150, but the flap 160 is provided on the upper surface with the accessory portion 101 being symmetrically configured via the central surface in the front-rear direction. It may be configured to be continuously provided from the right side of the portion 150. In that case, the main body portion 3 also has a symmetrical configuration via the central surface in the front-rear direction. In this way, in the case of a symmetrical configuration, in the case of manufacturing the packaging box, in FIG. 7, the main body portion 3 and the sub-body portion 101 are arranged symmetrically (that is, the front and back sides are reversed). Will be done.

Further, when the sub-body portion 101 is closed, the tip end (side portion 110c) of the front surface portion 110 is in contact with the upper surface of the bottom surface portion 50, but the length from the base end to the tip end of the front surface portion 110 is determined. It may be shortened so that the tip of the front surface portion 110 does not come into contact with the bottom surface portion 50 when the sub-body portion 101 is closed. When shortening the length from the base end to the tip end of the front surface portion 110, the side portion 110c at the tip end of the front surface portion 110 needs to be covered by the lateral portion 12, so that the sub-body portion 101 is closed. When the state is set, the vertical position of the side portion 10d is set above the side portion 110c.

Further, in the bottom surface portion 50, the first piece portion 60 is continuously provided from the front portion 10 and the second piece portion 70 is continuously provided from the side surface portion 20, but the main body portion 3 in the assembled state is connected in the left-right direction. When the length is longer than the length in the front-rear direction, the front portion 10 to the second piece portion 70 may be continuously provided, and the side surface portion 20 may be connected to the first piece portion 10. Even in that case, the tip portion 74 is formed on the side of the first piece portion 60 of the second piece portion 70, and for example, the first piece portion 60 and the second piece portion 70 are the first pieces in the deployed state of the main body portion 3. It becomes symmetrical via the center line between the portion 60 and the second piece portion 70. Similarly, the side surface portion 30 is connected to the third piece portion 80, and the back surface portion 40 is connected to the fourth piece portion 90. However, the side surface portion 30 to the fourth piece portion 90 are connected to the back surface. A configuration may be configured in which the third piece portion 80 is continuously provided from the portion 40. Even in that case, the tip portion 84 is formed on the side of the fourth piece portion 90 in the third piece portion 80, and for example, the third piece portion 80 and the fourth piece portion 90 are the third piece in the expanded state of the main body portion 3. It becomes symmetrical via the center line between the portion 80 and the fourth piece portion 90.

Further, although the main body portion 3 has been described as having the above configuration, the main body portion 3A shown in FIG. 21 may be used instead of the main body portion 3. That is, in the main body portion 3A, the configurations of the front surface portion 10 and the side surface portion 20 are different from those in the case of the main body portion 3.

That is, the front portion 10 of the main body portion 3A has a square shape (strictly speaking, the corners of the upper left and right ends are chamfered in a substantially arc shape), and unlike the main body portion 3, a notch portion is provided. No.

Further, the side surface portion 20 has a rectangular shape (specifically, a rectangular shape), and a substantially U-shaped cut line K24 is formed. The cut line K24 is formed in a straight line from the upper side of the side surface portion 20 downward in parallel with the polygonal line C2, and the cut line K24b is connected from the lower end of the cut line K24a and formed in an arc shape. And the cut line K24c which is connected from the end of the cut line K24c and is formed linearly in parallel with the polygonal line C7, and the cut which is connected from the end on the front side of the cut line K24c and formed in an arc shape. It has a line-of-sight line K24d and a line-of-sight line K24e formed linearly in parallel with the polygonal line C1 from the end portion of the line-of-sight line K24d to the upper side of the side surface portion 20. It is in contact with the upper side of the side surface portion 20. The length between the cut line K24a and the polygonal line C2 and the length between the cut line K24e and the polygonal line C1 are the same. It is formed symmetrically. The side surface portion 20 corresponds to the specific side surface portion, and the cut line K24 corresponds to the “cut line for forming the cutout portion, which is a cut line for forming the notch portion opened upward on the specific side surface portion”.

The area surrounded by the side portion along the cut line K24 and the upper side of the side surface portion 20 is the cut portion 24, and the side surface portion 20 is the main body portion 22 which is an area other than the cut portion 24 and the cut portion 24 in the side surface portion 20. And have. That is, by breaking the cut line K24, the cut portion 24 surrounded by the side portion along the cut line K24 and the upper side of the side surface portion 20 is removed from the side surface portion 20, and the main body portion 22 is opened upward. A notch is provided. Through this notch, the stored items in the displayed state can be visually recognized.

Since the configuration of the main body 3A other than the above is the same as that of the main body 3, detailed description thereof will be omitted.

Further, the sub-body portion to be adhered to the main body portion 3A has the same configuration as the sub-body portion 101 shown in FIG. 5, and the back surface portion 140 of the sub-body portion 101 is adhered to the separation portion 44 of the back surface portion 40.

The method of manufacturing the packaging box using the main body portion 3A is the same as that of the packaging box 1, and the method of using the packaging box is also the same except that the side surface portion 20 side is the front side of the display.

That is, when the items to be stored are stored in the main body 3A, the items to be stored are stored so that the side surface 20 side is the front side in the display, and when the items to be stored are stored, the same as in the case of the packaging box 1. In addition, the upper surface portion 150 is rotated toward the front side, and the flap 160 is inserted into the main body portion 3A in a state of being bent with respect to the upper surface portion 150, and the front surface portion 110 is in a state of being bent with respect to the upper surface portion 150. Inserted into the portion 3A so that the flap 160 is inside the side surface portion 20 and the front surface portion 110 is inside the front surface portion 10, and the upper surface side of the main body portion 3A is closed by the upper surface portion 150. It is in a state of being.

When displaying the items to be stored, as in the case of the packaging box 1, the cut line K44 was broken to separate the sub-body portion 101 from the main body portion 3A, and the sub-body portion 101 (separation portion 44 was adhered). Remove the accessory part 101). After that, the cut line K24 is broken and the cut portion 24 is separated from the side surface portion 20, so that the main body portion 20 is provided with a notch portion. Then, the items to be stored are displayed with the side surface portion 20 side (that is, the main body portion 22 side) as the front side in the display.

In this way, since the side surface portion 20 side can be the front side in the display, when the lateral length of the side surface portion 20 is longer than the lateral length of the front surface portion 10, the lateral width on the front side in the display Can be enlarged and displayed. That is, in the main body portion 3 and the main body portion 3A, the length along the lower side of the side surface portion 20 of the second piece portion 70 is the length of the side surface portion 10 of the first piece portion 60 in view of the configuration of the bottom surface portion 50 one-touch bottom. It may be formed longer than the length along the lower side, and then the width of the side surface portion 20 becomes longer than the width of the front surface portion 10. Therefore, by setting the side of the side surface portion 20 as the front side in the display, the front surface portion 20 is formed. The width of the front side of the display can be made longer than the side of the portion 10 as the front side of the display, and for example, it can be used when the width of the stored object is long. That is, when the bottom surface portion is composed of a one-touch bottom, a member continuously provided from one portion having a structure in which the tip portion is bent with respect to the main body portion, such as the second piece portion 70 and the third piece portion 80. The length along the lower side of the sleeve-shaped part) may be longer than the length along the lower side of the piece adjacent to the piece, so when you want to increase the width of the front side in the display. In addition, as shown in FIG. 21, a method of forming a cut line K24 on the side surface portion 20 can be used. That is, in the configuration shown in FIG. 21, the side surface portions 20 and 30 which are members (members constituting the sleeve-shaped portion) connected continuously from one portion having a configuration in which the tip portion is bent with respect to the main body portion are displayed. It can be on the front side and the back side. Further, in the configuration shown in FIG. 21, in FIG. 4, the front portion 10 to the second piece portion 70 are continuously connected, the side surface portion 20 to the first piece portion 60 are continuously provided, and the side surface portion 30 to the fourth piece portion 90 are connected. It is effective to increase the width of the front side in the display when the configuration is such that the back surface portion 40 and the third piece portion 80 are continuously provided and the third piece portion 80 cannot be connected due to the influence of the manufacturing apparatus.

In the example of FIG. 21, it is assumed that the cut line K24 is formed on the side surface portion 20, but instead of forming the cut line K24 on the side surface portion 20, a cut line having the same configuration as the cut line K24 is formed on the side surface portion 30. You may. Even in this case, the width of the front side of the display can be increased.

As shown in FIG. 21, as a method of forming the front side and the back side in the display, the members connected from one part of the structure in which the tip portion is bent with respect to the main body portion are as the configuration shown in FIG. May be good. That is, in the main body portion 3B of the packaging box 1A shown in FIG. 22, the back surface portion 40 is continuously provided from the second piece portion 70 via the polygonal lines C7-1 and C7-2, and the polygonal line C9 is provided from the third piece portion 80. The front surface portion 10 is continuously provided via the first piece portion, the side surface portion 20 is continuously provided from the first piece portion via the polygonal line C6, and the side surface portion 30 is continuously provided from the fourth piece portion 90 via the polygonal line C8. Further, in the sub-body portion 101A, the flap 170 is continuously provided from the side portion on the right side surface side of the upper surface portion 150. The flap 170 has the same configuration as the flap 170 of the accessory portion 101B described later. Further, in the upper surface portion 150, the protruding portions 155 and 157 are formed on the right side surface side. The projecting portions 155 and 157 have the same configuration as the projecting portions 155 and 157 of the upper surface portion 150 of the auxiliary body portion 101B described later. Further, the protruding portion 158 is provided along the side portion on the left side surface side of the main body portion 152 of the upper surface portion 150. The back surface portion 140 continuously provided from the upper surface portion 150 is adhered to the outer surface of the separation portion 44. In FIG. 22, instead of the protruding portions 155 and 157 shown in FIG. 22, the protruding portions 153B, 155 and 157 shown in FIG. 26 may be provided.

Even with the configuration shown in FIG. 22, the lateral lengths of the members (back surface portion 40, front surface portion 10) serially connected to the second piece portion 70 and the third piece portion 80 are the first piece portion 60 and the fourth. When it is longer than the lateral length of the members (side surface portions 20, 30) connected from the one portion 90, the lateral width of the front side (front portion 10 side in FIG. 22) in the display can be increased.

Comparing the configuration of FIG. 21 and the configuration of FIG. 22, in the configuration of FIG. 22, in the main body portion 3B, the configuration of each portion constituting the sleeve-shaped portion 5 is different from the configuration of FIG. Is also different from the configuration of the sub-body portion 101 shown in FIG. 5, whereas in the configuration shown in FIG. 21, the configurations of the front portion 10 and the side surface portion 20 may be changed from the configuration of FIG. Further, since the configuration of the sub-body portion may be the same as that shown in FIG. 5, it can be said that both the configuration of FIG. 3 and the configuration of FIG. 21 can be obtained with less effort.

Further, in the above description, the flaps in the sub-body portion 101 are connected from only one side portion in the upper surface portion 150, but as shown in FIG. 23, the two opposing sides in the upper surface portion 150 are connected. The flaps may be connected continuously from the part. That is, in the sub-body portion 101B shown in FIG. 23, the flap 160 is continuously provided from the side portion on the left side surface side of the upper surface portion 150 via the polygonal lines C13-1, C13-2, and C13-3. The flap 170 is continuously provided from the side portion on the right side surface side of the upper surface portion 150 via the polygonal lines C14-1, C14-2, and C14-3.

The flap (second flap) 170 has the same configuration except that the flap (second flap) 170 is formed symmetrically with the flap 160 via the center line in the front-rear direction in the deployed state of the accessory portion 101B. That is, the flap 170 has a substantially trapezoidal shape. When the accessory portion 101B is closed, the flap 170 is arranged inside the side surface portion 30 along the inner surface of the side surface portion 30.

Further, in the sub-body portion 101B, a protruding portion (second protruding portion) 155, 157 is provided on the right side surface side of the upper surface portion 150. The projecting portion 155 has the same configuration as the projecting portion 154 in the deployed state of the subbody portion 101B, except that the projecting portion 154 is formed symmetrically with the projecting portion 154 via the center line in the front-rear direction, and the projecting portion 157 has the same configuration. In the deployed state of the sub-body portion 101B, the configuration is the same except that the sub-body portion 101B is formed symmetrically with the protruding portion 156 via the center line in the front-rear direction. The protruding portion 155 and the protruding portion 157 are provided by forming a notch at the boundary position between the upper surface portion 150 and the flap 170 in the expanded state of the subbody portion 101B.

That is, both the protruding portion 155 and the protruding portion 157 are formed in a substantially trapezoidal shape in which the width becomes narrower (that is, the length in the front-rear direction becomes shorter) toward the tip side, and the base of the protruding portions 155 and 157. The length from the end to the tip is convex when the sub-body portion 101B is closed (that is, in the closed state of the sub-body portion 101B, the upper surface portion 150 covers the upper surface of the main body portion 3). The inner surface of the portions 155 and 157 (that is, the lower surface of the protruding portion 155 and 157 when the upper surface portion 150 covers the upper surface of the main body portion 3) is on the upper side of the upper side of the side surface portion 30 and is in contact with the upper side. It is the length. Specifically, the tip of the projecting portion 155, 157 has a length slightly protruding toward the right side surface from the outer surface of the side surface portion 30. Depending on the degree of bending of the upper surface portion 150, only a part of the inner surface of the protruding portion 155 and 157 is in contact with the upper side of the side surface portion 30, and the other portion of the inner surface of the protruding portion 155 and 157 is the side surface. It may be located above the upper side of the portion 30, and depending on the degree of bending of the upper surface portion 150, when the accessory portion 101B is allowed to stand in the closed state, the protruding portions 155 and 157 are located on the side surface portion 30. It may be located above the upper side of the side surface portion 30 without touching the upper side (even in this case, by pressing the upper surface portion 150 from above, the protruding portions 155 and 157 come into contact with the upper side of the side surface portion 30. ), In any case, the protruding portions 155 and 157 are on the upper side of the upper side of the side surface portion 30. That is, in order for the inner surface of the projecting portion 155, 157 to be on the upper side of the upper side of the side surface portion 30, the tip of the projecting portion 155, 157 is a surface on the right side of the inner surface of the side surface portion 30 in the left-right direction. It may be on the side (that is, the outside). The protruding portion 155 and the protruding portion 157 are formed in the same shape.

According to the sub-body portion 101B, the flaps 170 are continuously provided on the right side surface side of the upper surface portion 150, and the protruding portions 155 and 157 are provided in the places where the flaps 170 are not connected. Therefore, when the sub-body portion 101B is closed, a gap opened upward is not formed inside the upper side of the side surface portion 30, and it is possible to prevent dust and dirt from entering.

Further, since the projecting portions 155 and 157 are provided, when the sub-body portion 101B is closed, the lower surface of the projecting portions 155 and 157 is on the upper side of the upper side of the side surface portion 30, so that the sub-body portion is provided. The strength of the packaging box in the closed state of the portion 101B can be maintained high, and for example, even if a force is applied to the upper surface portion 150 from above, the upper surface portion 150 can be prevented from sinking downward.

Further, the packaging box may be composed of the main body portion 3C and the sub-body portion 101C as in the packaging box 1B shown in FIGS. 24 to 26.

The main body portion 3C has a different structure of the sleeve-shaped portion 5 from the main body portion 3 of FIG. The front surface portion 10 is continuously connected from the side surface portion 30 via the polygonal line C1, the side surface portion 20 is continuously provided from the front surface portion 10 via the polygonal line C2, and the back surface portion 40 is connected to the side surface portion 20.

The 80 is continuously connected from the lower side of the back surface portion 40 via the polygonal lines C9-1 and C9-2, and the fourth piece 90 is continuously connected from the lower side of the side surface portion 20 via the polygonal line 8. The side surface portion 20 constitutes a surface on the left side surface side of the main body portion 3C, and the side surface portion 30 constitutes a surface on the right side surface side of the main body portion 3C.

The front portion 10 in the main body portion 3C has the same configuration as the front portion 10 in the main body portion 3, but the upper side 10Ta of the front portion 10 is at the same height as the upper side of the side surface portion 20, and the upper side 10Tb of the front portion 10 Is at the same height as the upper side of the side surface portion 30. Further, the side surface portion 20 in the main body portion 3C has the same configuration as the side surface portion 20 in the main body portion 3, and the side surface portion 30 in the main body portion 3C has the same configuration as the side surface portion 30 in the main body portion 3. The back surface portion 40 in 3C has the same configuration as the back surface portion 40 in the main body portion 3. The back surface portion 40 is divided into a main body portion 42 and a separation portion 44 via a cut line K44.

Further, the bottom surface portion 50 has the same configuration as the bottom surface portion 3 of the main body portion 3, but the fourth piece portion 90 is not provided with a notch as compared with the case of the main body portion 3, so that the third piece portion is provided. The tip 84 of the 80 is not provided with a notch like the notch K84.

The glue margin portion 49 is adhered to the area on the back surface side of the side surface portion 30, but since the flap 160 is inserted inside the side surface portion 30 along the side surface portion 30, the glue margin portion 49 is the side surface portion 30. It is preferable to adhere to the outer surface. The glue margin portion 49 may be adhered to the inner surface of the side surface portion 30.

Further, in the bottom surface portion 50 of the main body portion 3C, the tip portion 74 is adhered to the lower surface of the first piece portion 60 and the tip portion 84 is attached to the lower surface of the fourth piece portion 90, similarly to the bottom surface portion 50 of the main body portion 3. Be glued.

Further, the sub-body portion 101C has substantially the same configuration as the sub-body portion 101B, but the upper surface portion 150 is provided with three projecting portions (second projecting portions) 153A, 154, and 156 on the left side surface side. At the same time, the difference is that three projecting portions 153B, 155, and 157 are provided on the right side surface side, and the configurations of the flaps 160 and 170 and the front portion 110 are different.

That is, in the upper surface portion 150, the protruding portion 153B is formed so as to project from the front side end portion on the right side surface side of the main body portion 152 toward the right side surface side, and the polygonal line C14 is formed from the front side end portion of the polygonal line C14-1.

It has a side portion 153Bc serially formed from the side portion 153Bc and formed in a substantially arc shape, and a side portion 153Bd serially formed from the end portion of the side portion 153Bc and formed on an extension line of the polygonal line C11. The protruding portion 153A is formed symmetrically with the protruding portion 153B via the center line in the front-rear direction.

Further, the configuration of the projecting portions 154 and 156 is the same as that of the projecting portions 154 and 156 in the sub-body portion 101B, but the sub-body portion 101C is provided with the projecting portions 153A. Compared with the case of the sub-body portion 101B, the protruding portions 154 and 156 are provided at positions shifted to the back surface side. Further, the projecting portion 155 is formed symmetrically via the center line, and the projecting portion 157 is formed symmetrically via the center line.

Further, the flap (second flap) 160 has substantially the same configuration as the flap 160 of the sub-body portion 101, but its shape is slightly different, and the flap (second flap) 160 is continuously provided from the front end portion of the folding line C13-1. A side portion 160f having an acute angle with respect to -1, a linear side portion 160a connected from the end portion of the side portion 160e and forming a right angle with respect to the direction of the bending line C13-1, and an end portion of the side portion 160a. The side portion 160b which is continuously connected from the side and has a substantially arc shape, the linear side portion 160c which is continuously connected from the end portion of the side portion 160b and parallel to the bending lines C13-1 to C13-3, and the end portion of the side portion 160c. A side portion 160d which is continuously connected from the side and has a substantially arc shape, and a side portion 160d which is continuously connected from the end portion of the side portion 160d and formed up to the end portion on the back side of the folding line C13-3, which is inclined at an acute angle with respect to the folding line C13-3. It has a linear side portion 160e. That is, it is different from the flap 160 of the sub-body portion 101 in that the tip on the front side of the flap 160 forms a substantially right angle and the side portion 160e is provided. The side portion 160f faces the side portion of the protruding portion 153A (the side portion symmetrical with the side portion 153Ba of the protruding portion 153B) in the expanded state of the subbody portion 101C, and protrudes from the side portion 160f. It is adjacent to the side portion of the shaped portion 153A via a notch.

Further, the flap (second flap) 170 has the same configuration except that the flap (second flap) 170 is formed symmetrically with the flap 160 via the center line in the front-rear direction in the deployed state of the accessory portion 101C.

Further, the front portion 110 of the sub-body portion 101C has substantially the same configuration as the front portion 110 of the sub-body portion 101, but its shape and the length from the base end to the tip are different.

That is, the front portion 110 is a linear side portion 110a-1 and a side portion 110a-1 connected in a direction perpendicular to the bent line C11 from the end portion on the left side surface side of the bent line C11 with the upper surface portion 150. A linear side portion 110a-2 that is continuously provided from the end portion and is inclined at an acute angle with respect to the direction of the bending line C11, and an arc shape (may be a substantially arc shape) that is continuously provided from the end portion of the side portion 110a-2. ), A linear side portion 110c connected from the end portion of the side portion 110b, and an arc-shaped (may be substantially arcuate) side portion connected from the end portion of the side portion 110c. 110d and a straight side portion 110e-2 which is connected from the end portion of the side portion 110d and inclined at an acute angle with respect to the direction of the folding line C11, and the right side surface side of the folding line C11 from the end portion of the side portion 110e-2. It has a linear side portion 110e-1 formed up to the end portion of the above and forming an acute angle with the folding line C11. That is, the side portions 110a-2 and 110e-2 are formed in a tapered shape, and the front portion 110 has a tapered shape.

Here, the length (length between the polygonal line C11 and the side portion 110c) L110 from the base end to the tip end of the front surface portion 110 is formed to be shorter than the length L110 in the front surface portion 110 of the subbody portion 101, and is a subbody. When the portion 101C is closed, the tip of the front portion 110 does not touch the bottom portion 50. The length L110 is formed to be longer than the vertical length L11a of the notch K10 of the front portion 10, and the length of the side portion 110c of the front portion 110 is the length of the notch K10 in the left-right direction. It is formed longer than L11b, and when the sub-body portion 101C is closed, the notch portion K10 is closed from the inside by the front portion 110, and the front side of the main body portion 3 is closed (that is, the front portion). It is in a state of being covered from the inside of 10. The accessory portion 101C is formed symmetrically with respect to the center line in the front-rear direction in the deployed state.

The main body portion 3C and the sub-body portion 101C are adhered to each other at the separation portion 44, as in the case of the main body portion 3 and the sub-body portion 101. That is, the outer surface of the separation portion 44 and the inner surface of the back surface portion 40 are adhered to each other by an adhesive or other adhesive means, so that the packaging box 201 is integrally formed as a whole. The adhesive force of the adhesive layer is such that when the back surface portion 40 is pulled outward, the cut line K44 is broken, the separation portion 44 is separated from the main body portion 3C, and the separation portion 44 is adhered to the back surface portion 40. The adhesive force is such that it follows the back surface portion 40.

Further, in the state where the main body portion 3C and the sub-body portion 101C are adhered to each other, the upper sides 40Ta, 40Tb, 40Tc of the back surface portion 40 and the polygonal line C12 are substantially aligned (may be matched) in the height direction. Strictly speaking, the polygonal line C12 is slightly above the upper side 40Ta to 40Tc. As a result, when the upper surface of the main body 3C is closed by the upper surface portion 150, the projecting portions 154, 156, 153A are in contact with the upper side of the side surface portion 20, and the projecting portions 155, 157, 153B are on the upper side of the side surface portion 30. It is possible to prevent the formation of a gap between the upper surface portion 150 and the upper sides of the side surface portions 20 and 30 in contact with each other.

Further, in a state where the main body portion 3C and the sub-body portion 101C are adhered to each other, the lower end of the back surface portion 40 and the lower end of the back surface portion 40 are aligned (may be substantially the same).

The manufacturing process of the packaging box 1B having the above configuration is substantially the same as the manufacturing process of the packaging box 1. That is, first, the main body portion 3C and the sub-body portion 101C in the expanded state are manufactured. Next, the outer surface of the main body portion 3C is adhered to the inner surface of the sub-body portion 101C (first bonding step). That is, with the inner surface of the sub-body portion 101C in the unfolded state facing upward, the adhesive is applied to the adhesive region with the separated portion 44 on the back surface portion 40, and the main body portion 3C in the unfolded state is overlapped. As a result, the separated portion 44 and the back surface portion 40 are bonded (first bonding step). At that time, the lower side of the back surface portion 40 and the lower side of the back surface portion 40 are made to match (may be substantially the same). An adhesive may be applied to the region of the outer surface of the separation portion 44 to adhere the separation portion 44 to the back surface portion 40.

Next, each portion constituting the bottom surface portion 50 of the main body portion 3C is folded back inward with respect to the sleeve-shaped portion 5, and the tip portion 74 of the second piece portion 70 is folded outward with respect to the main body portion 72. 3 The tip portion 84 of the piece portion 80 is folded outward with respect to the main body portion 82. That is, the first piece 60 is folded back toward the side surface portion 30 via the polygonal line C6, the second piece 70 is folded back toward the front portion 10 via the polygonal line C7, and the third piece 80 is folded back toward the front portion 10 via the polygonal line C9-1, C9. Fold back to the back surface 40 side via -2, fold back the fourth piece 90 to the side surface portion 20 side via the polygonal line C8, further fold the tip portion 74 with respect to the main body portion 72, and the tip portion 84 to the main body. Fold back to the part 82.

Next, an adhesive is applied to the region of the tip portion 74 (adhesive application step), and the side surface portion 30 is folded inward toward the front portion 10 via the folding line C1 (second folding step). The portion 74 is adhered to the first piece portion 60 (second bonding step). Instead of the tip portion 74, an adhesive may be applied to the adhesive region of the first piece portion 60 with the tip portion 74.

Next, an adhesive is applied to the region of the tip portion 84 and the region of the glue margin portion 49 (adhesive application step), and the back surface portion 40 is folded inward toward the side surface portion 20 via the polygonal line C3. Then, the tip portion 84 and the fourth piece portion 90 are adhered, and the glue margin portion 49 is adhered to the outer surface of the side surface portion 30 (third bonding step). Instead of the glue margin portion 49, an adhesive may be applied to the adhesive region of the side surface portion 30 with the glue margin portion 49, and instead of the tip portion 84, the tip portion 84 of the fourth piece portion 90 may be applied. An adhesive may be applied to the area to be adhered to. As described above, the packaging box 1B is manufactured. The above manufacturing is automatically manufactured by the assembly device. As described above, since the packaging box 1B can be manufactured by the first bonding step to the third bonding step, the packaging box 1B can be easily manufactured. When the glue margin portion 49 is adhered to the inner surface of the side surface portion 30, the back surface portion 40 is folded back with the adhesive applied to the tip portion 84, and then the tip portion 74 and the glue margin portion 49 are attached. The side surface portion 30 will be folded back with the adhesive applied.

According to the manufacturing method of the packaging box 1B, the side surface portion 30 is folded back toward the front surface portion 10, and the back surface portion 40 is folded back toward the side surface portion 20, so that the front surface portion 10 is folded back as compared with the case of the packaging box 1. There is no need, and there is an effect that it is easy to perform the folding operation. That is, since the front portion 10 is provided with the notch K10, it is difficult to grab the front portion 10 with a jig and fold it back when assembling by the assembling device, but in the case of the packaging box 1B, the notch is used. Since it is not necessary to fold back the front portion 10 provided with the portion K10, as a result, the packaging box can be easily manufactured.

When the main body portion 3C and the sub-body portion 101C are adhered to each other, whether or not the relative positions of the main body portion 3C and the sub-body portion 101C are correct should be confirmed by a notch for alignment confirmation as described above. Can be done.

In the above manufacturing process, the step of folding the third piece portion 80 toward the side surface portion 30, folding the fourth piece portion 90 toward the back surface portion 40, and further folding the tip portion 84 with respect to the main body portion 82 is This is performed after the side surface portion 30 is folded back toward the front portion 10 and the tip portion 74 is adhered to the first piece portion 60, and then before the adhesive is applied to the region of the tip portion 84 and the region of the glue margin portion 49. You may. In that case, in the folding step, the first piece 60 and the second piece 70 are folded back, the tip portion 74 is folded back, and then the adhesive is applied to the tip portion 74.

Further, the adhesive is applied to the tip portion 74 in a state where the second piece portion 70 is folded back and the tip portion 74 is folded back, but the second piece portion 70 is in a state before being folded back with respect to the side surface portion 20. After applying the adhesive to the tip portion 74, the tip portion 74 may be folded back while folding back the second piece portion 70.

Further, the adhesive is applied to the tip portion 84 in a state where the third piece portion 80 is folded back and the tip portion 84 is folded back, but the third piece portion 80 is in a state before being folded back with respect to the side surface portion 30. After applying the adhesive to the tip portion 84, the tip portion 84 may be folded back while folding back the third piece portion 80. The adhesive may be applied to the tip portion 84 after the tip portion 74 and the first piece portion 60 are adhered to each other.

Further, the method of using the packaging box 1B is the same as that of the packaging box 1. When the auxiliary body portion 101C is closed, the front portion 110 and the flaps 160 and 170 are bent with respect to the upper surface portion 150, and the front portion is used. The portion 110 is arranged inside the front portion 10 along the inner surface of the front portion 10, the flap 160 is arranged inside the side portion 20 along the inner surface of the side portion 20, and the flap 170 is arranged on the side surface. It is arranged inside the portion 30 along the inner surface of the side surface portion 30, and the upper surface portion 150 is in a state of covering the upper surface of the main body portion 3C.

Since the flap 170 is provided in the sub-body portion 101B shown in FIG. 23 and the sub-body portion 101C shown in FIG. 26, when the stored object is a hard object such as a box, the side surface portion 30 is provided. A gap is also provided between the flap 170 and the object to be stored so that the flap 170 can be arranged inside the side surface portion 30.

The packaging box 1B may also be symmetrical via the central surface in the front-rear direction. In that case, the side surface portion 20 constitutes the surface on the right side surface of the main body portion 3C, and the side surface portion 30 constitutes the surface on the left side surface side of the main body portion 3C. That is, when the first side surface portion of the main body portion is on the left side surface side and the second side surface portion of the main body portion is on the right side surface side, the side surface portion 20 is the first side surface portion of the main body portion and the side surface portion 30 is the second side surface portion of the main body portion. On the contrary, when the first side surface portion of the main body portion is on the right side surface side and the second side surface portion of the main body portion is on the left side surface side, the side surface portion 20 becomes the second side surface portion of the main body portion and the side surface portion 30 becomes the main body portion. It becomes the first side surface part.

In the main body portion 3B, the glue margin portion 49 may be continuously provided from the side surface portion 20, and in the main body portion 3C, the glue margin portion 49 may be continuously provided from the side surface portion 30.

Further, in the above description, although it is assumed that the four side surfaces of the main body portion 3 are formed by the sleeve-shaped portion 5, the front portion, the two side surface portions, and the back surface portion are formed from each side of the rectangular plate-shaped bottom surface portion. And are connected to each other, and the front part, the two side surface parts, and the back side parts adjacent to each other may be connected to each other via the glue margin part. As the glue margin portion, for example, in the two side surface portions, the glue margin portion is continuously provided on the front side and the back surface side via a broken line, and the glue margin portion is adhered to the front portion and the back surface portion. In the case of such a configuration, the side component portion is configured by the front portion, the two side surface portions, and the back surface portion.

Next, the packaging box 201 of the second embodiment will be described. The packaging box 201 is configured as shown in FIGS. 27 to 30, and the packaging box 201 has a main body portion 203 and a sub-body portion 301 adhered to the main body portion 203.

Each of the main body portion 203 and the sub-body portion 301 is a blank in the form of a sheet (specifically, a blank made of corrugated cardboard (for example, made of thin corrugated cardboard), and is made of another paper such as a cardboard blank. It may be blank). That is, the packaging box 201 is a paper packaging box such as a corrugated cardboard material (particularly, a double-sided corrugated cardboard material). The direction of the step of the core having a substantially corrugated cross section in the cardboard is the direction shown in the circle in FIGS. 29 and 30, and in the main body 203, it is parallel to the polygonal lines C21 to C24 (note that it is parallel to the polygonal lines C21 to C24). The direction of the step of the core in the cardboard is not limited to this), and in the sub-body portion 301, the direction is perpendicular to the polygonal lines C31a, C31b, and C32. The direction of the core step in corrugated cardboard is not limited to this).

It is formed in a substantially trapezoidal shape. Since the flap 360 has the same configuration as the frame 160 of the first embodiment, detailed description thereof will be omitted.

On the left side of the upper surface portion 350, the flaps 360 are continuously provided, and in the places where the flaps 360 are not connected, the protruding portions 354 and 356 are provided, so that the sub-body portion 301 is provided. When the side surface portion 320 is in the closed state, a gap opened upward is not formed inside the upper side of the side surface portion 320, and it is possible to prevent dust and dirt from entering.

When the sub-body portion 301 is closed, the insertion piece 322 is inserted into the insertion portion 212 from the outside of the front portion 210, and the flap 360 is inside the side surface portion 220 and inside the side surface portion 220. The upper surface portion 350 is in a state of covering the upper surface of the main body portion 203, and the upper surface portion 350 is in a state of being along the upper sides of the side surface portions 220 and 230, and the bottom surface portion 250 (particularly, sleeve-shaped) is arranged. It is parallel (may be substantially parallel) to the plane surrounded by the lower side of the portion 205 (the plane surrounded by the polygonal lines C26 to C29). Further, when the sub-body portion 301 is closed, the upper surface portion 350 is at a right angle to the back surface portion 340 (may be a substantially right angle), and the front portion 310 (particularly, the main body portion 320) and the flap 360 are formed. , Right angle with respect to the upper surface portion 350 (may be substantially right angle).

Further, although the flap 360 is continuously connected from the left side surface side of the upper surface portion 350, it is not continuously connected to the right side surface side of the upper surface portion 350, but the reason is the same as in the case of the first embodiment. be.

The main body portion 203 and the sub-body portion 301 are adhered to each other at the separation portion 244. That is, the outer surface of the separation portion 244 and the inner surface of the back surface portion 340 are adhered to each other by an adhesive or other adhesive means, so that the packaging box 201 is integrally formed as a whole. That is, an adhesive layer (not shown) is provided between all or a part of the outer surface of the separation portion 244 and a part of the inner surface of the back surface portion 340. The adhesive strength of the adhesive layer is such that when the back surface portion 340 is pulled outward, the cut line K244 is broken, the separation portion 244 is separated from the main body portion 203, and the separation portion 244 is adhered to the back surface portion 340. The adhesive force is such that it follows the back surface portion 340.

In the main body portion 203 and the sub-body portion 301, a ruled line is formed in advance at each polygonal line. In particular, in the broken lines C21, C22, C23, C24, C26, C27, C28, and C29, the ruled lines are pressed from the inner surface of the main body 203, and the broken lines C31a, C31b, C32, C33-1, and C33-2. , C33-3 is a ruled line pressed from the inner surface of the sub-body portion 301. Since the polygonal lines 700-1 and 280-1 on the bottom surface portion 250 are mountain-folded when viewed from the upper surface side, it is preferable to use a ruled line pressed from the outer surface.

Further, in the state where the main body portion 203 and the sub-body portion 301 are adhered to each other, the upper sides 240Ta and 240Tb of the back surface portion 240 and the polygonal line C32 are substantially aligned (may be matched) in the height direction. The polygonal line C32 is slightly above the upper sides 240Ta and 240Tb. As a result, when the upper surface of the main body 203 is closed by the upper surface portion 350, the protruding portions 354 and 356 are in contact with the upper side of the side surface portion 220 and the protruding portion 358 is in contact with the upper side of the side surface portion 230. It is possible to prevent the formation of a gap between the upper sides of the side surface portions 220 and 230.

Further, in a state where the main body portion 203 and the sub-body portion 301 are adhered to each other, the lower end of the back surface portion 340 and the lower end of the back surface portion 240 are aligned (may be substantially the same).

The manufacturing process of the packaging box 201 having the above configuration is substantially the same as the manufacturing process of the packaging box 1 of the first embodiment, but since the glue margin portion 249 is adhered to the inside of the front portion 210, the side surface portion 230 is folded back. The difference is that the front portion 210 is folded back later.

That is, first, the main body portion 203 and the sub-body portion 301 in the expanded state are manufactured. Next, the outer surface of the main body portion 203 is adhered to the inner surface of the sub-body portion 301 (first bonding step). That is, with the inner surface of the sub-body portion 301 in the unfolded state facing upward, the adhesive is applied to the adhesive region with the separated portion 244 in the back surface portion 340, and the main body portion 203 in the unfolded state is shown in FIG. 31. Stack. As a result, the separation portion 244 and the back surface portion 340 are bonded (first bonding step). At that time, the lower side of the back surface portion 240 and the lower side of the back surface portion 340 are made to match (may be substantially the same). An adhesive may be applied to the region of the outer surface of the separation portion 244 to adhere the separation portion 244 to the back surface portion 340.

Next, each portion constituting the bottom surface portion 250 of the main body portion 203 is folded inward with respect to the sleeve-shaped portion 205, and the tip portion 274 of the second piece portion 270 is folded outward with respect to the main body portion 272. 3 The tip portion 284 of the piece portion 280 is folded outward with respect to the main body portion 282 to bring about the state shown in FIG. 32 (folding step). That is, the first piece 260 is folded back toward the front portion 210 via the polygonal line C26, the second piece 270 is folded back toward the side surface 220 via the polygonal line C27, and the third piece 280 is folded back toward the side surface via the polygonal line C29. The fourth piece 290 is folded back to the back surface 240 side via the polygonal line C28, the tip portion 274 is folded back to the main body portion 272, and the tip portion 284 is folded back to the main body portion 282. The state shown in FIG. 32 is assumed.

Next, an adhesive is applied to the region of the tip portion 284 (adhesive application step), and the side surface portion 230 is folded inward toward the back surface portion 240 via the folding line C23 (second folding step). The portion 284 is bonded to the fourth piece portion 290 (second bonding step). Instead of the tip portion 284, an adhesive may be applied to the adhesive region of the fourth piece portion 290 with the tip portion 284.

Next, an adhesive is applied to the region of the tip portion 274 and the region of the glue margin portion 249 (adhesive application step), and the front portion 210 is folded inward toward the side surface portion 220 via the polygonal line C21. , The state shown in FIG. 33. Then, the tip portion 274 and the first piece portion 260 are bonded, and the glue margin portion 249 is bonded to the inner surface of the front surface portion 210 (third bonding step). Instead of the glue margin portion 249, an adhesive may be applied to the adhesive region of the front surface portion 210 with the glue margin portion 249, and instead of the tip portion 274, the tip portion 274 in the first piece portion 260 may be applied. An adhesive may be applied to the area to be adhered to. As described above, the packaging box 201 is manufactured. The above manufacturing is automatically manufactured by the assembly device. As described above, since the packaging box 201 can be manufactured by the first bonding step to the third bonding step, the packaging box 201 can be easily manufactured. When the glue margin portion 249 is adhered to the outer surface of the front portion 210, the front portion 210 is folded back with the adhesive applied to the tip portion 274, and then the tip portion 284 and the glue margin portion 249 are attached. The side surface portion 230 will be folded back with the adhesive applied.

When the main body portion 203 and the sub-body portion 301 are adhered to each other, whether or not the relative positions of the main body portion 203 and the sub-body portion 301 are correct is checked for alignment, as in the case of the first embodiment. It can be confirmed by the notch. Since the method of confirming the alignment is the same as that of the first embodiment, detailed description thereof will be omitted.

In the above manufacturing process, the step of folding the second piece 270 to the side surface 220 side, folding the first piece 260 to the front surface 210 side, and further folding the tip 274 to the main body 272 is After folding the side surface portion 230 toward the back surface portion 240 and adhering the tip portion 284 to the fourth piece portion 290, the process is performed before applying the adhesive to the region of the tip portion 274 and the region of the glue margin portion 249. May be good. In that case, in the folding step, the third piece portion 280 and the fourth piece portion 290 are folded back, the tip portion 284 is folded back, and then the adhesive is applied to the tip portion 284.

Further, the adhesive is applied to the tip portion 274 in a state where the second piece portion 270 is folded back and the tip portion 274 is folded back, but the second piece portion 270 is in a state before being folded back with respect to the side surface portion 220. After applying the adhesive to the tip portion 274 (or the first piece portion 260), the tip portion 274 may be folded back while folding back the second piece portion 270. The adhesive may be applied to the tip portion 274 after being adhered to the tip portion 284 and the fourth piece portion 290.

Further, the adhesive is applied to the tip portion 284 in a state where the third piece portion 280 is folded back and the tip portion 284 is folded back, but the third piece portion 280 is in a state before being folded back with respect to the side surface portion 230. After applying the adhesive to the tip portion 284 (or the fourth piece portion 290), the tip portion 284 may be folded back while folding back the third piece portion 280.

A method of using the packaging box 201 having the above configuration will be described. When the packaging box 201 is not used, the packaging box 201 can be folded into a flat plate shape as shown in FIG. 34, so that the packaging box 201 is folded and stored.

Next, when using the packaging box 201, the packaging box 201 is assembled. That is, the front surface portion 210 and the back surface portion 240 of the main body portion 203 are parallel to each other, the side surface portions 220 and the side surface portions 230 are parallel to each other, and the bottom surface portion 250 is perpendicular to the sleeve-shaped portion 205. By assembling, the packaging box 201 is assembled as shown in FIGS. 27 and 28.

Then, as shown in FIG. 35, the stored object (product) G is stored in the main body portion 203. When the main body 203 is assembled from the state of FIG. 34, as shown in FIGS. 27 and 28, the upper surface portion 350 and the front surface portion 310 are in a state of extending upward and above the main body portion 203. Is in an open state, the stored object G may be stored as it is from above the main body portion 203. If the stored object is soft, there is no problem in inserting the side surface portion 220 even if a gap is not provided between the front portion 210 or the side surface portion 220 and the stored object, but the stored object G is used. In the case of a hard object such as a box as shown in FIG. 35, a gap is provided between the side surface portion 220 and the stored object. Further, also in the front portion 310, since the insertion piece 322 is inserted toward the inside of the front portion 210, if the stored object G is hard, a gap is provided between the front portion 210 and the stored object. I will set it up.

After storing the stored object G, the accessory portion 301 is closed and the stored object is packaged. That is, the upper surface portion 350 is rotated toward the front side, and the flap 360 is inserted into the main body portion 203 in a state of being bent with respect to the upper surface portion 350 (that is, the flap 360 is inside the side surface portion 220). ), The insertion piece 322 is inserted into the insertion portion 212 from the outside with the front portion 310 bent with respect to the upper surface portion 350, so that the state shown in FIGS. 36 to 38 is obtained. That is, the flap 360 is set to be inside the side surface portion 220, and the insertion piece 322 is inserted into the insertion portion 212 so that the upper surface side of the main body portion 203 is closed by the upper surface portion 350. To insert the insertion piece 322 into the insertion portion 212, the insertion piece 322 is inserted into the opening 214 while pushing the piece portion 218 with the insertion piece 322. By inserting the insertion piece 322 into the insertion portion 212, the insertion state is established.

When the sub-body portion 301 is closed, the upper surface portion 350 covers the upper surface of the main body portion 203, the lower surface of the protruding portions 354 and 356 is in contact with the upper side of the side surface portion 220, and further, the protruding portion. The lower surface of the 358 touches the upper side of the side surface portion 230. Further, the main body portion 320 is in a state parallel to the front portion 210 and along the outer surface of the front portion 210.

After the packaged object G is packaged in the packaging box 201 as described above, the packaging box 201 is transported to the place where the packaged object G is displayed.

After that, when displaying the items to be stored, the cut line K244 is broken to separate the sub-body portion 301 from the main body portion 203. That is, the insertion piece 322 is pulled out from the insertion portion 212 (may be a drawer) to release the insertion state, and then the cut line K244 is broken. When the insertion piece 322 is pulled out from the insertion portion 212, for example, a finger is hooked on the lower end of the main body portion 320 of the front portion 310 to pull the main body portion 320 upward, and when the cut line K244 is broken, for example, for example. By pulling the main body 320 outward while holding the main body 320 of the front portion 310 by hand, the cut line K244 is broken downward from the upper end. The cut line K244 is broken by pulling the separation portion 244 outward while the upper surface portion 350 is open to the outside of the back surface portion 340 and the separation portion 244 is in contact with the inner surface of the upper end region of the separation portion 244. You may. If the inner surface of the separation portion 244 cannot be brought into contact with the inner surface of the separation portion 244 due to the storage of the stored object G, the main body portion 320 or the upper surface portion 350 of the front portion 310 is held by hand on the back side. It is preferable to break the cut line K244 by pulling to.

Then, by removing the sub-body portion 301 (strictly speaking, the sub-body portion 301 to which the separation portion 244 is adhered), the state shown in FIGS. 39 and 40 is obtained. Therefore, the side of the back surface portion 240 is the front side in the display. As a result, the stored object G is displayed. That is, since the separation portion 244 is separated, a notch portion (a notch portion including the notch portion K240 and the notch portion due to the removal of the separation portion 244) K249 is formed on the back surface portion 240. The stored object can be visually recognized through the notch K249.

After removing the insertion piece 322 from the insertion portion 212, the upper surface portion 350 is rotated upward by hand with the main body portion 320 of the front portion 310, and the main body portion 320 is pulled toward the back side as it is to form the cut line K244. Since it can be broken, the insertion piece 322 can be pulled out (may be pulled out) and the cut line K244 can be broken by one series of operations.

As described above, according to the packaging box 201 of the present embodiment, since it is only necessary to break the cut line K244 and separate only the separation portion 244, the work of removing the sub-body portion 301 (a part of the packaging box 201) is performed. It can be easily performed, and the display work of the items to be stored can be easily performed. In particular, the operation of pulling out the insertion piece 322 and the separation of the separation portion 244 by breaking the cut line K244 can be performed in a series of operations. Therefore, the display work of the items to be stored can be easily performed.

When the sub-body portion 301 is closed, the upper surface portion 350 covers the upper surface of the main body portion 203, the lower surface of the protruding portions 354 and 356 is on the upper side of the upper side of the side surface portion 220, and further, the protruding portion Since the lower surface of the 358 is on the upper side of the upper side of the side surface portion 230, the strength of the packaging box 201 can be maintained high. Further, also in the front portion 310, when the insertion piece 320 is inserted into the insertion portion 212, the main body portion 320 is supported by the insertion piece 320, and the lower end of the main body portion 320 goes below the insertion portion 212. Since there is no front portion 310, the upper surface portion 350 is also supported, and the strength of the packaging box 201 in the closed state of the accessory portion 301 can be maintained high. For example, a force is applied to the upper surface portion 350 from above. Even if it is added, it is possible to prevent the upper surface portion 350 from sinking downward.

Further, as in the case of the first embodiment, since the main body portion 203 and the sub-body portion 301 have a substantially rectangular shape in the expanded state, the blank area can be effectively utilized. That is, when two packaging boxes 201 of this embodiment are formed from sheet-shaped blanks, the area of the region R101 may be sufficient as shown in FIG. 41.

On the other hand, if it is attempted to form two packaging boxes 1101 that are similar to the one in which the main body portion 203 and the sub-body portion 301 are integrated with one blank, the configuration shown in FIG. 42 is obtained, and the area of the region R111 is required. Since the two regions shown in the hatching in FIG. 42 are wasted, the area of the region R101 can be made smaller than the area of the region R111.

In the packaging box 1101 shown in FIG. 42, the upper surface portion 350 is continuously provided from the back surface portion 240'to the cut line K240', and the back surface portion 240'has a separation portion unlike the packaging box 201. Not provided. When displaying the items to be stored, the cut line K240'is broken to remove the upper surface portion 350, the front portion 310, and the flap 360. In this packaging box 1101, since the back surface portion 240'and the upper surface portion 350' are connected to each other by the cut line K240', the cut line K240'is likely to break when a force is applied to the upper surface portion 350 from above. It can be said that the strength is weaker than that of the packaging box 201 of this embodiment. That is, in the packaging box 201 of the present embodiment, although the back surface portion 240 and the back surface portion 340 overlap each other, the main body portion 203 and the sub-body portion 301 both exhibit a substantially rectangular shape, so that the blank area is effective. It can be utilized, and further, since there is no cut line along the side portion of the upper surface portion 350, it can be said that the strength can be increased.

In the above description, the flap 360 is connected from the left side surface side of the upper surface portion 350, but the flap 360 is configured so that the accessory portion 301 is symmetrically arranged via the central surface in the front-rear direction, and the flap 360 is on the upper surface. It may be configured to be continuously provided from the right side of the portion 350. In that case, the main body 303 also has a symmetrical configuration via the central surface in the front-rear direction. In this way, in the case of a symmetrical configuration, in the case of manufacturing the packaging box, in FIG. 31, the main body portion 203 and the sub-body portion 301 are arranged symmetrically (that is, the front and back sides are reversed). Will be done.

Further, in the above description, it is said that by breaking the cut line K244, a notch portion integrated with the notch portion K240 is formed on the back surface portion 240, but instead of the cut line K244 on the back surface portion 240. A configuration in which an endless (or peripheral) cut line is provided, the area surrounded by the endless cut line is used as a separation portion, and when the separation portion is separated, an opening is formed in the back surface portion 240. May be. Even in that case, the stored object can be visually recognized from the outside through this opening.

Further, in the bottom surface portion 250, the first piece portion 260 is continuously connected from the front portion 210, and the second piece portion 270 is connected continuously from the side surface portion 220, but the main body portion 203 in the assembled state is connected in the left-right direction. When the length is longer than the length in the front-rear direction, the front portion 210 may be connected to the second piece portion 270, and the side surface portion 220 may be connected to the first piece portion 210. Even in that case, the tip portion 274 is formed on the first piece portion 260 side of the second piece portion 270, and for example, the first piece portion 260 and the second piece portion 270 are the first pieces in the expanded state of the main body portion 203. It becomes symmetrical via the center line between the portion 260 and the second piece portion 270. Similarly, it was said that the third piece 280 was connected from the side surface 230 and the fourth piece 290 was connected from the back surface 240, but the fourth piece 290 was connected from the side surface 230 to the back surface. A configuration may be configured in which the third piece portion 280 is continuously provided from the portion 240. Even in that case, the tip portion 284 is formed on the fourth piece portion 290 side of the third piece portion 280, and for example, the third piece portion 280 and the fourth piece portion 290 are the third piece in the expanded state of the main body portion 203. Left-right line symmetry is achieved via the center line between the portion 280 and the fourth piece portion 290.

Further, in the above description, it is assumed that the flaps in the sub-body portion 301 are continuously provided from only one side portion in the upper surface portion 150, but as shown in FIG. 43, two opposing sides in the upper surface portion 350 are provided. It may be configured as a series from the department. That is, in the sub-body portion 301A shown in FIG. 43, the flap 360 is continuously provided from the side portion on the left side surface side of the upper surface portion 350 via the polygonal lines C33-1, C33-2, and C33-3. The flap 370 is continuously provided from the side portion on the right side surface side of the upper surface portion 350 via the polygonal lines C34-1, C34-2, and C34-3.

The flap (second flap) 370 has the same configuration except that the flap (second flap) 370 is formed symmetrically with the flap 360 via the center line in the front-rear direction in the deployed state of the accessory portion 301A. That is, the flap 370 has a substantially trapezoidal shape. When the accessory portion 301A is closed, the flap 370 is arranged inside the side surface portion 230 along the inner surface of the side surface portion 230.

Further, in the sub-body portion 301A, a protruding portion (second protruding portion) 355, 357 is provided on the right side surface side of the upper surface portion 350. The projecting portion 355 has the same configuration as the projecting portion 354 in the deployed state of the subbody portion 301A, except that the projecting portion 354 is formed symmetrically with the projecting portion 354 via the center line in the front-rear direction, and the projecting portion 357 has the same configuration. In the deployed state of the sub-body portion 301A, the configuration is the same except that the sub-body portion 301A is formed symmetrically with the protruding portion 356 via the center line in the front-rear direction. The protruding portion 355 and the protruding portion 357 are provided by forming a notch at the boundary position between the upper surface portion 350 and the flap 370 in the deployed state of the subbody portion 301A.

That is, both the protruding portion 355 and the protruding portion 357 are formed in a substantially trapezoidal shape in which the width becomes narrower (that is, the length in the front-rear direction becomes shorter) toward the tip side, and the base of the protruding portions 355 and 357. The length from the end to the tip is convex when the sub-body portion 301A is closed (that is, in the closed state of the sub-body portion 301A, the upper surface portion 350 covers the upper surface of the main body portion 203). The inner surface of the portions 355 and 357 (that is, the lower surface of the protruding portion 355 and 357 when the upper surface portion 350 covers the upper surface of the main body portion 203) is on the upper side of the upper side of the side surface portion 230 and is in contact with the upper side. It is the length. Specifically, the tip of the protruding portion 355, 357 has a length that slightly protrudes to the right side surface side from the outer surface of the side surface portion 230. Depending on the degree of bending of the upper surface portion 350, only a part of the inner surface of the protruding portion 355, 357 touches the upper side of the side surface portion 230, and the other portion on the inner surface of the protruding portion 355, 357 is the side surface. It may be located above the upper side of the portion 230, and depending on the degree of bending of the upper surface portion 350, when the auxiliary body portion 301A is allowed to stand in a closed state, the protruding portions 355 and 357 may be located on the side surface portion 230. It may be located above the upper side of the side surface portion 230 without touching the upper side (even in this case, by pressing the upper surface portion 350 from above, the protruding portions 355 and 357 come into contact with the upper side of the side surface portion 230. ), In any case, the protruding portion 355, 357 is on the upper side of the upper side of the side surface portion 230. That is, in order for the inner surface of the projecting portion 355, 357 to be on the upper side of the upper side of the side surface portion 230, the tip of the projecting portion 355, 357 is a surface on the right side of the inner surface of the side surface portion 230 in the left-right direction. It may be on the side (that is, the outside). The protruding portion 355 and the protruding portion 357 are formed in the same shape.

According to the sub-body portion 301A, the flaps 370 are continuously provided on the right side surface side of the upper surface portion 350, and the protruding portions 355 and 357 are provided in the places where the flaps 370 are not continuously provided. Therefore, when the sub-body portion 301A is closed, a gap opened upward is not formed inside the upper side of the side surface portion 330, and it is possible to prevent dust and dirt from entering.

Further, since the projecting portion 355, 357 is provided, when the sub-body portion 301A is closed, the lower surface of the projecting portion 355, 357 is on the upper side of the upper side of the side surface portion 330, so that the sub-body portion is provided. The strength of the packaging box in the closed state of the portion 301A can be maintained high, and for example, even if a force is applied to the upper surface portion 350 from above, the upper surface portion 350 can be prevented from sinking downward.

Further, in the above description, although it is assumed that the four side surfaces of the main body portion 203 are formed by the sleeve-shaped portion 205, the front portion, the two side surface portions, and the back surface portion are formed from each side of the rectangular plate-shaped bottom surface portion.
