  Hereinafter, 1st embodiment of the packaging box of this invention is described based on FIGS. As shown in FIG. 1, the packaging box 10 of this embodiment is a substantially rectangular parallelepiped having a rectangular tube-shaped body portion 12 having four side surfaces, a lid portion 14 that closes an opening of the body portion 12, and a bottom portion 16. And is formed by assembling a single box forming piece 18 made of cardboard or the like.

  As shown in FIG. 2, the box-forming piece 18 has four side plates 20, 22, 24, and 26 that are connected in parallel to each other. The side plates 20, 22, 24, 26 have the same length in the width direction orthogonal to the connecting direction, and the length in the connecting direction is substantially equal to each other because the side plates 20, 24 are long. Are short and almost equal to each other. At the end on the side plate 20 side, a glue piece 28 is provided that is glued to the back surface of the end of the side plate 26 in the assembled state. The glue piece 28 and the four side plates 20, 22, 24, 26 are separated by crease lines 30, 32, 34, 36, respectively. Hereinafter, the side plate 20 is referred to as a first side plate 20, and the side plate 24 is referred to as an inner plate 24.

  A substantially rectangular lid piece 38 extends from one end of the first side plate 20 in a direction perpendicular to the connecting direction, and is separated from the first side plate 20 by a crease line 40. The lid piece 38 is a part that becomes the lid portion 14 in the assembled state, and the length of the lid piece 38 in the extending direction is substantially the same as the length of the side plate 22 in the connecting direction.

  A substantially rectangular outer plate 42 extends from the end of the lid piece 38 opposite to the crease line 40, and is separated from the lid piece 38 by the crease line 44. The outer plate 42 includes an opening portion 46 that is continuous with the lid piece 38 and a gluing portion 48 that is a discontinuous portion with the lid piece 38. The opening portion 46 has an isosceles trapezoidal shape in which the end on the side continuous to the lid piece 38 is wide and the opposite end is narrow, and the narrow end bulges in an arc shape. Thus, it is divided from the gluing part 48 by the breaking line 50 for opening. The breaking line 50 for opening is comprised by the straight line and curve which the notch part and the short connection part continued. The inner side of the arcuate portion of the opening portion 46 is a finger hanging portion 52 to which the user applies a finger at the time of opening, and the finger hanging portion 52 has an anti-slip unevenness with respect to the user's finger in a V shape. The cut line 52a is provided. The cut line 52a is provided so that the V-shaped top portion faces the crease line 44, and indicates the direction in which the finger is moved. The glue portion 48 is a portion that is glued to the outer surface of the inner plate 24 in an assembled state.

  Further, an outer bottom piece 54 having substantially the same shape as the lid piece 38 is extended to the other end portion of the first side face plate 20, and is separated from the first side face plate 20 by a crease line 56.

  A trapezoidal side flap 58 extends from an end of the side plate 22 that is continuous with the crease line 40 of the first side plate 20, and is separated from the side plate 22 by the crease line 60. A trapezoidal side flap 62 extends from the other end of the side plate 22 and is separated from the side plate 22 by a crease line 64. Of the two tip corners of the side flap 62, the tip corner far from the side plate 24 is obliquely divided by a crease line 66a to form a substantially triangular bent portion 66. The crease line 66a is formed by a cut line having a predetermined length, for example.

  An arc-shaped notch 68 a is provided at the center of the end 68 of the inner plate 24 that is continuous with the crease line 60 of the side plate 22. An inner bottom piece 70 that is slightly smaller than the outer bottom piece 54 extends from the other end of the inner plate 24, and is separated from the inner plate 24 by a break line 72.

  A pressing position display 74 is printed at a position near the break line 72 at the boundary between the side plate 22 and the inner plate 24. For example, as shown in FIG. 2, the pressed position display 74 is a pattern or the like that combines a character “PUSH” and a U-shaped symbol. The pressing position display 74 will be described later.

  A trapezoidal side flap 76 is extended at an end of the side plate 26 that is continuous with the end side 68 of the inner plate 24, and is separated from the side plate 26 by a crease line 78. A trapezoidal side flap 80 extends from the other end of the side plate 26 and is separated from the side plate 26 by a crease line 82. Of the two tip corners of the side flap 80, the tip corner far from the inner plate 24 is obliquely divided by a crease line 84a to form a substantially triangular bent portion 84. The crease line 84a is formed by, for example, a notch of a predetermined length.

  In addition, a first cut-out portion 26 a surrounded by an edge 88 facing the crease line 36 and a U-shaped break line 86 is provided at the center of the side plate 26. On the surface of the first cut-off portion 26a, information about the object to be contained (for example, letters “ABC” and the like) is displayed, and a small notch 88a is provided in the approximate center of the end portion on the end side 88 side. Yes.

  In the center portion of the glue piece 28, a second cut-out portion 28a surrounded by an end side facing the crease line 30 and a U-shaped break line 90 is provided. The second cut-off portion 26a is a portion to be fitted and glued inside the first cut-out portion 26a in an assembled state.

  Next, an example of a method for assembling the packaging box 10 will be described. Here, the folding method in which the front surface of the box-forming piece 18 is convex is referred to as normal folding, and the folding method in which the back surface is convex is referred to as reverse folding.

  First, the crease line 30 is folded forward and the glue piece 28 is stacked on the first side plate 20, the glue 92 is applied to the surface of the second cut-off portion 28 a of the glue piece 28, and the other part of the glue piece 28 (first Adhesive 94 is applied to the surface of two places other than the second separation portion 28a. Then, the crease line 34 is forward-folded, the second separation portion 28a is glued to the back surface of the first separation portion 26a of the side plate 26, and the other part of the glue piece 28 is attached to the other part of the side plate 26. Glue to the back. The box forming piece 18 is shipped in the folded state.

  Next, in a factory or the like for packaging products, the crease lines 30, 32, 34, and 36 are each normally folded at 90 degrees to form the square cylindrical body 12. Thereafter, in order to provide a bottom portion 16 for closing one end portion of the body portion 12, the side flaps 62, 80 are respectively set to 90 degrees at the crease lines 64, 82 as shown in FIGS. 3 (a), (b), (c). The inner bottom piece 70 is folded forward at 90 degrees along the breaking line 72. Thereafter, paste 96 is applied to the center of the back surface of the outer bottom piece 54, the outer bottom piece 54 is normally folded at 90 degrees along the crease line 56, and the outer bottom piece 54 is glued to the surface of the inner bottom piece 70. A bottom portion 16 in which the inner bottom piece 70 is integrated is formed. Now, as shown in FIG. 4A, one end of the body 12 is closed, so that a product or the like is inserted from the other open end. In FIG. 4A, the letters “ABC” displayed on the surface of the side plate 26 are omitted.

  In order to provide the lid portion 14 that closes the other end portion of the body portion 12 after the product or the like is placed, the side flaps 58 and 76 are each normally folded at 90 degrees along the crease lines 60 and 78, and the glue portion 48 of the outer plate 42 is adhered. Apply glue 98 to Then, the lid piece 38 is normally folded at 90 degrees with the crease line 40, the outer plate 42 is correctly folded at 90 degrees with the crease line 44, and the outer plate 42 is neatly stacked on the surface of the inner plate 24. When the inner plate 24 is glued, the other end portion of the body portion 12 is also closed by the lid portion 14 formed of the lid piece 38. This completes the packaging operation of the product, and the assembled state shown in FIGS. 1A and 1B is obtained. The product is shipped from the factory and sold in a store or the like. In the assembly procedure, the lid portion 14 may be provided first, and the bottom portion 16 may be provided after the product is put.

  In the case of the packaging box 10, the lid portion 14 that closes the opening of the body portion 12 in the assembled state is a lid piece 38. Moreover, the 1st side surface in which the base end part of the cover part 14 continues among the several side surfaces which the trunk | drum 12 has is the 1st side plate 20 in which the base end part of the cover piece 14 continues. Of the plurality of side surfaces of the body portion 12, the second side surface facing the first side surface while the distal end portion of the lid portion 14 continues is an outer plate 42 and an inner plate 24 (side plate 24). It is a surface that is glued together.

  The user who has purchased the product opens the lid 14 and puts in and out the product. When opening the lid portion 14, as shown in FIG. 5A, an operation is performed in which the finger Yu is lightly pressed against the finger hook portion 52 of the opening portion 46 and the finger Yu is moved in the direction of the lid portion 14. Thereby, the opening part 46 slides in the surface direction along the outer surface of the inner plate 24, and as shown in FIG. 5B, the joint part of the breaking line 50 for opening breaks and the lid part 14 can be opened and closed. become.

  This opening operation is very simple and, as in Patent Document 1 described above, the troublesome operation of “pulling the pulling allowance with a finger and picking it with a finger” is unnecessary. In particular, in the case of the packaging box 10, the breaking line 50 for opening has the shape of the opening 46 in an isosceles trapezoidal shape in which the end on the side continuous to the lid piece 38 is wide and the end on the opposite side is narrow. In addition, since the finger hook portion 52 is disposed inside the narrow end portion bulging in an arc shape, a strong force is applied when the finger Yu is moved in the direction of the lid portion 14. Even if not, the whole breaking line 46 for opening can be broken at the same time. Further, since the finger hanging portion 52 is provided with irregularities made of the cut lines 52a, when the finger Yu is moved, the finger Yu adheres firmly to the surface of the finger hanging portion 52 and is difficult to slide. Therefore, even if the user is a child or an elderly person, the lid 14 can be easily opened with one action.

  After opening the lid 14, as shown in FIG. 6A, the first cutout portion 26 a of the side plate 26 can be separated from the body portion 12 and used as a convenient display card Ca. In this case, the user puts a finger on the notch 88a provided at the end of the first separation part 26a, pulls up the first separation part 26a, breaks the breaking line 86, and separates it from the side plate 26. Perform the operation. At this time, the second separation portion 28a glued to the back surface of the first separation portion 26a is also pulled up integrally, and the breaking line 90 is broken and separated from the glue piece 28. Therefore, the display card Ca has a double structure in which the second cut-off portion 28a is glued to the first cut-out portion 26a, so that the display card Ca is not easily damaged or bent.

  On the other hand, when the display unit Ca is not cut off and the cover part 14 is resealed and used, the side flaps 58 and 76 are normally folded at 90 degrees, the lid piece 38 is normally folded at 90 degrees, and the opening part 46 is opened. The side flaps 58 and 76 are inserted into the gap between the inner plate 24 and engaged. As a result, the end of the body 12 is closed, and the resealed state shown in FIG. Thereafter, when the lid portion 14 is opened again, it is easy to put the finger on the opening portion 46 exposed from the notch 68a provided on the end side 68 of the inner plate 24 and pull up the opening portion 46 and the lid piece 38. The lid 14 can be opened.

  When discarding the packaging box 10, the bottom 16 is disassembled in order to fold and reduce the volume. First, the torso 12 is held with one hand, and the portion of the pressing position display 74 (the corner where the side plate 22 and the inner plate 24 intersect) is pushed inward with the thumb of the holding hand. Then, as shown in FIG. 7A, the bottom portion 16 is disassembled when the body portion 12 is deformed and the breaking line 72 is broken. When the portion of the pressing position display 74 is pushed in, the side flap 62 inside the bottom portion 16 has a bent portion 66 on the inner surface of the first side plate 20 facing the inner plate 24 as shown in FIG. After the collision, the sheet is automatically folded at the crease line 66a. Since the bent portion 66 has the bottom portion 16 on the surface side, the bent portion 66 bends on the opposite side to the bottom portion 16.

  As described above, when the user pushes the portion of the pressing position display 74, the bent portion 66 is automatically bent in the process of deforming the trunk portion 12, so that the side flaps 62 are deformed. It will not be an obstacle to block. Therefore, the breaking line 72 can be smoothly broken, and the bottom 16 can be easily disassembled with one action. The side flap 80 is not particularly obstructed because it can protrude outward from the portion of the broken line 72 where the tip corner on the inner plate 24 side is separated.

  After the user disassembles the bottom portion 16, the user also opens the lid portion 14, folds the box thinly, and discards it while reducing the volume.

  Since the packaging box 10 is also provided with the bent portion 84 and the crease line 84a on the side flap 80, the bottom 16 is disassembled at the portion of the pressing position display 74 (the angle at which the side plate 22 and the inner plate 24 intersect). It is possible to perform the same operation even if the corner portion where the inner plate 24 and the side plate 26 intersect is pushed inward instead of the portion). For example, a user who has purchased a product stored in the packaging box 10 many times experiences the dismantling operation of the bottom 16 of the packaging box 10 many times, thereby “ Since it will be understood that it can be disassembled if it is pressed and deformed in the direction of the diagonal line, it can be opened without checking the pressing position display 74 one by one.

  In this case, a second pressing position display may be added to the corner where the inner plate 24 and the side plate 26 intersect. However, if there are two pressing position indications, the user may misunderstand that “they cannot be opened unless the two places are pressed at the same time”, so that one of them is displayed to be pressed.

  As described above, the packaging box 10 can be easily opened with a single action, and the bottom 16 can be easily disassembled with a single action, even if the user is a child or an elderly person. Can do. Further, a convenient display card Ca can be obtained by separating a part of the body 12.

  Next, 2nd embodiment of the packaging box of this invention is described based on FIGS. As shown in FIG. 8, the packaging box 100 according to the present embodiment includes a rectangular tube-shaped body portion 102 having four side surfaces, and a lid portion 104 and a lid portion 106 that block the opening of the body portion 102. It is a rectangular parallelepiped box, and is formed by assembling a single box forming piece 108 made of cardboard or the like.

  As shown in FIG. 9, the box-forming piece 108 has four side plates 110, 112, 114, 116 that are connected in parallel to each other. The side plates 110, 112, 114, 116 have the same length in the width direction orthogonal to the connecting direction, and the lengths in the connecting direction are substantially equal to each other because the side plates 110, 114 are long. Are short and almost equal to each other. At the end on the side plate 116 side, a substantially rectangular inner plate 118 is provided that is glued to overlap the back surface of the side plate 110 in an assembled state. The size of the inner plate 118 is slightly smaller than the side plate 110. The four side plates 110, 112, 114, 116 and the inner plate 118 are separated by crease lines 120, 122, 124, 126, respectively. Hereinafter, the side plate 110 is referred to as the outer plate 110, and the side plate 114 is referred to as the first side plate 114.

  A substantially rectangular second lid piece 128 extends from one end of the outer plate 110 in a direction perpendicular to the connecting direction, and is separated from the outer plate 110 by a crease line 130. The second lid piece 128 is a portion that becomes the lid portion 104 in the assembled state, and the length of the second lid piece 128 in the extending direction is substantially the same as or slightly shorter than the length of the side plate 112 in the connecting direction. At the other end of the outer plate 110, an outer bottom piece 132 having substantially the same shape as the second lid piece 128 is extended and separated from the outer plate 110 by a crease line 134.

  The outer plate 110 includes an opening portion 136 that is continuous with the second lid piece 128 and a gluing portion 138 that is a discontinuous portion with the second lid piece 128. The opening 136 has an isosceles trapezoidal shape in which the end on the side continuous to the second lid piece 128 is wide and the end on the opposite side is narrow, and the narrow end is bulged into an arc shape. In this way, it is separated from the pasting part 138 by the breaking line 140 for opening. An inside of the arcuate portion of the opening portion 136 is a finger hanging portion 142 to which the user applies a finger when opening, and the finger hanging portion 142 has an anti-slip unevenness on the user's finger, and isosceles triangular. It is provided by a through hole 142a having a shape. The through-hole 142a is provided so that the top of the isosceles triangle shape faces the crease line 130, and indicates the direction in which the finger is moved. The glue part 138 is a part that is glued to the outer surface of the inner plate 118 in an assembled state.

  A trapezoidal side flap 144 extends from an end portion of the side plate 112 that is continuous with the crease line 130 of the outer plate 110, and is separated from the side plate 112 by the crease line 146. A trapezoidal side flap 148 extends from the other end of the side plate 112 and is separated from the side plate 112 by a crease line 150. Of the two tip corners of the side flap 148, the tip corner far from the first side plate 114 is obliquely divided by a crease line 152a to form a substantially triangular bent portion 152. The crease line 152a is formed by a cut line having a predetermined length, for example.

  A first lid piece 154 slightly smaller than the second lid piece 128 is extended at an end of the first side plate 114 that is continuous with the crease line 146 of the side plate 112, and the first side plate 114 is formed by the crease line 156. Are separated. An inner bottom piece 158 that is slightly smaller than the outer bottom piece 132 is extended to the other end portion of the first side plate 114, and is separated from the first side plate 114 by a break line 160.

  A pressed position display 162 is printed at a position near the break line 160 at the boundary between the side plate 112 and the first side plate 114. For example, as shown in FIG. 9, the pressed position display 162 is a pattern or the like in which the characters “PUSH” and a U-shaped symbol are combined.

  A trapezoidal side flap 164 extends from an end of the side plate 116 that is continuous with the crease line 156 of the first side plate 114, and is separated from the side plate 116 by the crease line 166. A trapezoidal side flap 168 extends from the other end of the side plate 116 and is separated from the side plate 116 by a crease line 170. Of the two tip corners of the side flap 168, the tip corner far from the first side plate 114 is obliquely divided by a crease line 172a to form a substantially triangular bent portion 172. The crease line 172a is formed by, for example, a notch having a predetermined length.

  An arc-shaped cutout 174 is provided on an end of the inner plate 118 that is continuous with the crease line 166 of the side plate 116.

  Next, an example of an assembly method of the packaging box 100 will be described. Here, the folding method in which the front surface of the box-forming piece 108 is convex is referred to as normal folding, and the folding method in which the back surface is convex is referred to as reverse folding.

  First, the crease line 126 is folded forward and the inner plate 118 is overlaid on the side plate 116, and glue 176 is applied to the surface of the inner plate 118 (the portion excluding the vicinity of the notch 174). Then, the crease line 122 is forwardly folded, and the inner plate 118 is glued to the back surface of the gluing portion 138 of the outer plate 110. The box-forming piece 108 is shipped in this folded state.

  Next, in a factory or the like for packaging products, the crease lines 120, 122, 124, and 126 are each normally folded at 90 degrees to form the square cylindrical body 102. Thereafter, in order to provide the bottom portion 106 that closes one end of the body portion 102, the side flaps 148 and 168 are each normally folded at 90 degrees with the crease lines 150 and 170, and the inner bottom piece 158 is normally folded at 90 degrees with the breaking line 160. . Thereafter, paste is applied to the center of the back surface of the outer bottom piece 132, the outer bottom piece 132 is normally folded at 90 degrees along the crease line 134, and the outer bottom piece 132 is glued to the surface of the inner bottom piece 158. A bottom portion 106 in which the bottom piece 158 is integrated is formed. Thus, as shown in FIG. 10A, one end of the body 102 is closed, so that a product or the like is inserted from the other open end.

  In order to provide the lid portion 104 that closes the other end of the body portion 102 after the product is put in, the side flaps 144 and 164 are each normally folded at 90 degrees with the crease lines 146 and 166, and the first lid with the crease line 156 The piece 154 is folded forward. Thereafter, paste 178 is applied to the center of the back surface of the second lid piece 128, the second lid piece 128 is normally folded at 90 degrees along the crease line 130, and the second lid piece 128 is placed on the surface of the first lid piece 154. When gluing, the lid portion 104 in which the first lid piece 154 and the second lid piece 128 are integrated is formed, and the other end portion of the body portion 102 is also closed. As a result, the product packaging operation is completed, and the assembled state shown in FIG. In the assembly procedure, the lid portion 104 may be provided first, and the bottom portion 106 may be provided after the product is placed.

In the case of the packaging box 100, the lid portion 104 that closes the opening of the body portion 102 in the assembled state is a portion in which the first lid piece 154 and the second lid piece 128 are glued together. Of the plurality of side surfaces of the body portion 102, the first side surface where the base end portion of the lid portion 104 is continuous is the first side plate 114 where the base end portion of the first lid piece 154 is continuous. . Of the plurality of side surfaces of the body portion 102, the second side surface that is continuous with the front end portion of the lid portion 104 and faces the first side surface is an outer plate 110 (side plate 110) and an inner plate 118. The user who has purchased the product, which is a surface that is overlapped and glued together, opens the lid 104 and puts in and out the product. When opening the lid 104, as shown in FIG. 11A, the finger Yu is lightly pressed against the finger hook 142 of the opening 136 and an operation of moving the finger Yu in the direction of the lid 104 is performed. As a result, the opening portion 104 slides in the surface direction along the outer surface of the inner plate 118, and as shown in FIG. 11B, the joint portion of the opening breaking line 140 is broken, and the lid portion 104 can be opened and closed. become. And when the cover part 104 is opened largely, it will be in the open state shown in FIG.

  This opening operation is very simple, and the troublesome operation of “pulling the pulling margin with a finger and pulling it with a finger” as in Patent Document 1 described above is unnecessary. In particular, in the case of the packaging box 100, the breaking line 140 for opening has the shape of the opening portion 136 in an isosceles trapezoid shape in which the end on the side continuous to the lid piece 104 is wide and the end on the opposite side is narrow. In addition, since the finger-hanging part 142 is arranged on the inner side where the narrow end portion bulges out in an arc shape, a strong force is applied when the finger Yu is moved in the direction of the lid part 104. Even if it is not, the whole breaking line 140 for opening can be broken simultaneously. Further, since the finger hanging portion 142 is provided with irregularities including the through holes 142a, when the finger Yu is moved, the finger Yu adheres firmly to the surface of the finger hanging portion 142 and is difficult to slide. Therefore, even if the user is a child or an elderly person, the lid 104 can be easily opened with one action.

  When re-sealing the opened lid 104, the side flaps 144, 164 are folded forward at 90 degrees, the lid 104 is folded at 90 degrees along the crease line 156, and the opened section 136 is moved to the side flaps 144, 164. It is inserted into the gap with the inner plate 118 and engaged. As a result, the end portion of the body portion 102 is closed, and a resealed state is obtained. Thereafter, when the lid 104 is opened again, a finger is placed on the opening 136 exposed from the notch 174 provided on the edge of the inner plate 118, and the lid 136 and the lid 104 are pulled up to easily open the lid 104. Part 104 can be opened.

  When discarding the packaging box 100, the bottom 106 is disassembled in order to fold it down to reduce the volume. The operation of disassembling the bottom portion 106 is performed by grasping the trunk portion 102 with one hand, and using the thumb or the like of the grasping hand, the portion of the pressing position display 162 (the corner portion where the side plate 112 and the first side plate 114 intersect). Push inward. By this operation, as in the case of the packaging box 10 described above, the bottom portion 106 can be easily disassembled with one action. Thereafter, the lid 14 is also opened, the box is thinly folded, and discarded with the volume reduced.

  As described above, the packaging box 100 can easily open the sealed end type lid 104 with one action even if the user is a child or an elderly person, and the bottom 106 can be easily disassembled with one action. Can do.

  In addition, this invention is not limited to the said embodiment. For example, the shapes of the inner plate and the outer plate that form the second side surface of the body portion can be appropriately changed within a range in which the above-described operation at the time of opening is possible. The packaging box 10 allows the box-forming piece 18 to be manufactured at a lower cost by making the outer shape of the gluing portion 48 of the outer plate 42 relatively small. For example, the outer shape of the gluing portion 48 is increased, If it overlaps with a wide range of the inner plate 24 in the assembled state, the second side surface of the body portion 12 can be reinforced, and the packaging box 100 reinforces the second side surface of the body portion 102. The outer shape of the inner plate 118 is enlarged so as to overlap a wide range of the outer plate 110 in an assembled state. For example, a portion overlapping the gluing portion 138 so that the box forming piece 18 can be manufactured at a lower cost. The area may be reduced. On the other hand, if the length of the inner box 118 in the extending direction from the crease line 126 is increased to increase the area, and the inner plate 118 overlaps with the side plates other than the outer plate 110 in the assembled state, Other side surfaces (side surfaces other than the second side surface) of the body portion 12 can also be reinforced.

  The unevenness for preventing slipping of the finger-hanging portion of the opening portion may be provided by, for example, embossing or debossing, in addition to providing by a cut line or a through hole. In any case, it can be provided easily and inexpensively using a process of punching a box-forming piece from one blank sheet. In addition, in order to further enhance the anti-slip effect, the surface of the finger rest may be scratched or an anti-slip material may be provided.

  The number of side plates provided on the box-forming piece may be four or more, and the rectangular tube-shaped body may be formed from five or more side surfaces. Moreover, you may abbreviate | omit the structure for separating a display card from a trunk | drum, and the structure for dismantling a bottom part as needed.
