  Hereinafter, an embodiment of the resealable packaging box of the present invention will be described based on the drawings. As shown in FIG. 1, the packaging box 10 of this embodiment is a substantially rectangular parallelepiped box, and is formed by assembling a box forming piece 12 in which a single blank sheet such as cardboard is integrally punched. .

  FIG. 2 is a developed view of the box-forming piece 12 as viewed from the back side. The box-forming piece 12 includes a first side surface 14, a second side surface 16, a third side surface 18, and a fourth side surface that are connected in parallel to each other. 20. The four side surfaces 14, 16, 18, and 20 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 first and third side surfaces 14 and 18 are long. The second and fourth side surfaces 16, 20 are short and substantially equal to each other. At the end portion on the first side surface 14 side, a gluing piece 22 that is glued to the back surface of the end portion on the fourth side surface 20 side in the assembled state of the packaging box 10 is provided. The glue piece 22 and the four side surfaces 14, 16, 18, and 20 are divided by crease lines 24, 26, 28, and 30, respectively.

  The gluing piece 22 is formed in a trapezoid whose width decreases as the distance from the crease line 24 increases. A first card portion 32 is provided at the end of the glue piece 22 opposite to the crease line 24 and separated by a third break line 34. The first card part 32 has a rectangular shape that is long in the width direction perpendicular to the connecting direction, and the size of the first card part 32 and the glued piece 22 is the size of the glued piece 22 in the assembled state of the box-forming piece 12. It is smaller than the fourth side surface 20 to be made. A knob 36 is provided via a crease line 38 on one side edge of the first card 32 that intersects the third break line 34. The knob 36 has a shape that bulges outward in a semicircular shape.

  A trapezoidal first lid piece 40 having a narrow width on the front end side is extended at one end of the first side surface 14, and is separated from the first side surface 14 by a first crease line 42. The extending direction length of the first lid piece 40 is about 2/3 of the connecting direction length of the second and fourth side surfaces 16 and 20. At the other end of the first side surface 14, a lid piece 44 having the same shape as the first lid piece 40 is extended and separated from the first side surface 14 by a crease line 46.

  A flap 48 is extended at an end of the second side face 16 that is continuous with the first crease line 42 of the first side face 14, and is separated from the second side face 16 by the crease line 50. A flap 52 extends from the other end of the second side face 16 and is separated from the second side face 16 by a crease line 54.

  At the end of the third side face 18 that is continuous with the crease line 50 of the second side face 16, a reinforcing piece 56 is extended and separated by the second crease line 58. The length of the reinforcing piece 56 in the extending direction is about ½ of the second and fourth side surfaces 16 and 20. Inside the reinforcing piece 56, a trapezoidal through hole 60 is opened at an end portion on the second crease line 58 side.

  A re-sealing piece 62 extends from the tip of the reinforcing piece 56 and is delimited by a first breaking line 64. The length of the resealable piece 62 in the extending direction is substantially equal to the length of the reinforcing piece 56 in the extending direction. The resealing piece 62 has both ends of a boundary portion with the reinforcing piece 56 cut inward in a substantially V shape, and both corners of the cutout portion are arcuate.

  A substantially rectangular second lid piece 66 extends from the tip of the resealable piece 62 and is separated from the resealable piece 62 by a third fold line 68. The extending direction length of the second lid piece 66 is substantially equal to the connecting direction length of the second and fourth side surfaces 16 and 20. An emboss for ensuring contact with the back surface of the third side surface 18 facing the through hole 60 may be formed at the center of the resealable piece 62.

  At the other end of the third side surface 14, a lid piece 70 having the same shape as the second lid piece 66 is extended and separated from the third side surface 18 by a crease line 72. The lid piece 70 is provided with a V-shaped fourth breaking line 74 at a substantially central portion in the extending direction, and is divided into a distal end portion 70a and a proximal end portion 70b.

  Further, on the inner side of the third side surface 18, an opening portion 76 having a size smaller than the through hole 60 and capable of being pressed by a finger is provided at the end on the second crease line 58 side. It is surrounded by the second break line 78. The opening portion 76 of the third side surface 18 may be formed with a dent for ensuring contact with the surface of the reseal piece 62 that faces through the through hole 60.

  A flap 80 is extended at an end of the fourth side surface 20 that is continuous with the second crease line 58 of the third side surface 10, and is separated from the fourth side surface 20 by a crease line 82. A flap 84 extends from the other end of the fourth side surface 20 and is separated from the fourth side surface 20 by a crease line 86.

  Furthermore, a substantially rectangular second card portion 88 is provided inside the fourth side surface 20 at a position slightly closer to the crease line 86 from the center portion. The second card portion 88 is formed so as to be surrounded by a fifth break line 90.

  Various information such as names of contents and advertisements are printed on the surface of the box forming piece 12. On the first card unit 32, for example, a product name, detailed information on a product to be read by the user, and the like are printed. The second card portion 88 is printed with an expiration date, a product serial number, etc., for example, in a process of packaging the product described later.

  Next, an example of the assembly method of the packaging box 10 with a display piece is demonstrated. Here, the folding method in which the front surface of the box-forming piece 12 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, as shown in FIG. 2, paste 92 is applied to the back surface of the reinforcing piece 56, the second crease line 58 is normally folded as shown in FIG. 3, and the opening portion 76 is arranged inside the through hole 60. Thus, the back surface of the reinforcing piece 56 is glued to the back surface of the third side surface 18 other than the opening portion 76. Thereby, the peripheral edge part of the opening part 76 of the 3rd side surface 18 overlaps with the reinforcement piece 56, and is reinforced. Thereafter, as shown in FIG. 3, glue 94 is applied to the surface of the resealable piece 62, the first breaking line 64 is reversely folded as shown in FIG. 4, and the surface of the resealable piece 62 is placed on the back surface of the opening portion 76. Glue it. At this time, if a convex emboss is formed on the surface side of the resealable piece 62, the re-sealing piece 62 is more reliably glued. Similarly, even when the opening 76 is formed with a convex dent on the back surface side, adhesion is ensured.

  Next, as shown in FIG. 5, pastes 96 and 98 are applied to the end portions of the fourth side surface 20 and the back surface of the second card portion 88, respectively. Then, by folding the crease line 24 forward and further folding the crease line 28, the back surface of the end of the fourth side surface 20 is glued to the surface of the gluing piece 22, and the back surface of the second card part 88 is Glue the card surface. The box-forming piece 12 is shipped in this folded state.

  Next, in a factory or the like where products are stored and packaged, the crease lines 24, 26, 28, and 30 are each normally folded at 90 ° to form a rectangular cylindrical body. 7A, 7B, and 7C, the flaps 52 and 84 are each normally folded at 90 ° by the crease lines 54 and 86, and the lid piece 44 is correctly angled by 90 ° by the crease line 46. Fold it. Thereafter, the glue 100 is applied to the distal end side portion 70 a of the lid piece 70, the lid piece 70 is normally folded at 90 ° with the crease line 72, and the back surface of the lid piece 70 is glued to the surface of the lid piece 44. As a result, one end of the cylindrical body is closed to form the bottom, so that the product is put into the box from the other open end.

  Next, as shown in order in FIGS. 8A, 8B, and 8C, the flaps 48 and 80 are each normally folded at 90 ° by the crease lines 50 and 82, and the first lid piece 40 is 90 by the crease line 42. Fold it in degrees. Thereafter, the glue 102 is applied to the back surface of the second lid piece 64, the second lid piece 66 is normally folded at 90 ° by the third fold ruled line 68, and the back surface of the second lid piece 66 is placed on the surface of the first lid piece 40. Glue to. At this time, the knob portion 36 of the first card portion 32 is pushed by the lid portion of the box, is normally folded along the crease line 38, and is accommodated inside the box.

  Thereafter, the expiration date, serial number, etc. of the stored product are printed on the second card unit 88. This completes the product packaging operation, and the assembled state shown in FIG. 1 is obtained.

  Next, operations for opening and resealing the packaging box 10 will be described. When opening, the opening part 76 of the 3rd side surface 18 is pushed and broken with a finger. At this time, since the peripheral portion of the opening portion 76 is reinforced by the reinforcing piece 56, the third side face 18 is hardly deformed, and the second break line 78 can be easily broken. When the opening portion 76 is pushed and broken, the first break line 64 is also broken almost simultaneously, and the reseal piece 62 is separated from the reinforcing piece 56. The opening portion 76 is separated from the third side surface 18 but is not trashed because it is glued to the resealable piece 62. And if the reseal piece 62 and the 2nd cover piece 66 are picked and pulled up, as shown to Fig.9 (a), the edge part of a cylindrical body will open | release and it can take out the goods inside.

  Further, when the knob 36 of the first card part 32 is picked with a finger and pulled away from the fourth side face 20, the third break line 34 is broken as shown in FIG. Separate from the glue piece 22. At this time, since the second card portion 88 of the fourth side surface 20 is glued to the first card portion 32, the fourth break line 84 also breaks almost simultaneously, and the second card portion 88 is separated from the fourth side surface 20. . As a result, the first card part 32 and the second card part 88 are integrally separated from the box. Since the first card part 32 and the second card part 88 contain important information such as the product name and expiration date of the product, for example, when taking out the product from the packaging box 10 and storing it in a storage shelf or the like, It can be used as a display card for product identification.

  When the product is returned to the packaging box 10 after being opened and resealed, the resealing piece 62 is inserted into the gap between the flaps 40 and 80 and the third side face 18 as shown in FIG. To close the end of the cylindrical body. The resealing piece 62 can be easily inserted into the gap because both corners on the side of the first breaking line 64 that is separated are formed in an arc shape. The opening from which the opening 76 on the third side surface 18 has been removed is closed by the reseal piece 62. Since the opening portion 76 is glued to the surface of the resealable piece 62, it does not dull and looks good, and does not hinder the resealing operation.

  It is preferable that the width of the resealable piece 62 is set to be wide enough to fill the width of the third side surface 16, and the resealable piece 62 is locked more stably by contacting the inner surface of the third side surface 18 with a large area. can do. Further, if a pair of cuts are provided from both ends of the third crease 68, the cuts and the edges of the flaps 48 and 80 are engaged with each other, so that the closed state can be more reliably maintained.

  After disassembly, when disassembling the packaging box 10 for disposal, as shown in FIGS. 11 (a), 11 (b) and 11 (c), the center part of the bottom cover piece 70 is pushed in, and the fourth breaking line 74 is drawn. Break. Then, the closing of the bottom portion is easily released, and the packaging box 10 can be thinly folded, so that it can be discarded in a compact form.

  As described above, the packaging box 10 has a simple structure, is easy to assemble, and has good packaging workability. In addition, in the assembled state, the peripheral wall of the opening portion 76 is reinforced with the reinforcing piece 56, so that a good opening property can be stably realized. Can be resealed. In addition, compared with a normal sealed end type packaging box that does not have a reseal function, there is less addition of a portion extending from the box forming piece (reinforcing piece 56 and resealing piece 62 only), so one blank sheet Many box-forming pieces 12 can be punched out.

  In addition, the packaging box of this invention is not limited to the said embodiment. For example, in the packaging box 10, the second lid piece 66 is a large outer lid piece, and the first lid piece 40 is a small inner lid piece. Conversely, the first lid piece 40 is a large outer lid piece, The two lid pieces 66 may be changed to a small inner lid piece. Moreover, if the display card for merchandise identification is unnecessary, the 1st card | curd part 32, the 2nd card | curd part 88, and the structure relevant to this may be abbreviate | omitted. Moreover, you may abbreviate | omit the 4th broken line 74 for making disassembly of a box easy. Further, the glue 94 for fixing the opening portion 76 to the resealing piece 62 may be omitted for the efficiency of the assembly work. Even when these changes are made, the above-described good openability and resealability can be obtained.

  The size of the box, the material, the shape of each member, etc. can be changed as appropriate. Further, not only the top plate portion side but also the bottom portion side may be provided with the above reinforcing pieces and re-sealing pieces so that both sides of the cylindrical body can be opened and resealed.
