Hereinafter, the break line 76 is referred to as a second break line 76.

  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. 3A, the crease line 70 is folded forward, the proximal end portion 68a of the auxiliary plate 68 is overlapped with the second side plate 20, and the distal end portion 68b and the reseal piece 74 are attached. Overlap the side plate 18. Then, paste 78 is applied to a position near the crease line 70 on the surface of the base end side portion 68a, paste 80 is applied to the center portion of the surface of the tip end portion 68b, and paste is applied to the center portion of the surface of the reseal piece 74. 82 is applied.

  Thereafter, as shown in FIG. 3B, the crease line 24 is normally folded, and the end of the back surface of the side plate 14 is glued to the surface of the base end side portion 68b. Is glued to the surface of the tip end portion 68a, and the back surface of the unsealed portion 42 is glued to the surface of the resealable piece 74. The box-forming piece 12 is shipped in this folded state.

  Next, the crease lines 22, 24, 26, 70, and 72 are each normally folded at 90 degrees in a factory or the like that stores and packs products. Since the side plates 14 and 16 are each glued to the auxiliary plate 68, a solid rectangular tube can be formed in one action. 4A, 4B, and 4C, the side flaps 56 and 64 are each normally folded at 90 ° by the crease lines 58 and 66, and the lid piece 48 is 90 by the crease line 50. Fold it in degrees. Thereafter, glue 84 is applied to the distal end portion 32 b of the lid piece 32, the lid piece 32 is normally folded at 90 ° by the crease line 34, and the back surface of the lid piece 32 is glued to the surface of the lid piece 48. As a result, one end of the cylinder is closed and the bottom is formed, so that the product is put into the box from the other open end.

  Next, as shown in FIGS. 5A, 5B, and 5C in order, the side flaps 52 and 60 are each normally folded at 90 ° by the crease lines 54 and 62, and the second crease line 46 is used for the second crease line 46. The second lid piece 44 is folded forward at 90 °. Thereafter, paste 86 is applied to the back surface of the first lid piece 28, the first lid piece 28 is forward-folded at 90 ° by the first crease line 30, and the back surface of the first lid piece 28 is attached to the second Glue the surface of the lid piece 44.

  This completes the product packaging operation and the state shown in FIG. In this assembled state, the wide range of the first side plate 14 overlaps the tip side portion 68b of the auxiliary plate 68, and the peripheral portion of the opening portion 42 is reinforced.

  Next, operations for opening and resealing the packaging box 10 will be described. When opening, the opening part 42 of the 1st side plate 16 is pushed and broken with a finger. At this time, since the peripheral portion of the opening portion 42 is reinforced by the auxiliary plate 68, the first side plate 16 is not easily deformed, and the first break line 40 can be easily broken. When the opening 42 is pushed and broken, the second breaking line 76 is also broken almost simultaneously, and the reseal piece 74 is separated from the auxiliary plate 68. When the reseal piece 74 and the first lid piece 28 are picked up and pulled up, the third break line 38 is also broken, and as shown in FIG. The end is opened and the product inside can be taken out.

  When the product is returned to the packaging box 10 after being opened and resealed, the resealable piece 74 is placed in the gap between the side flaps 52 and 60 and the first side plate 16 as shown in FIG. By inserting and engaging, the end of the cylinder is closed with a lid. The resealable piece 74 can be easily inserted because both corners on the side of the second broken line 76 that has been cut off are taken. The opening from which the opening 42 of the first side plate 16 has been removed is closed by the reseal piece 74. Since the opening part 42 is glued on the surface of the reseal piece 74, it does not dull and looks good, and does not hinder the reseal operation.

  The width of the resealable piece 74 is preferably set to be wide enough to fill the width of the first side plate 16, and the resealable piece 74 is stabilized by contacting the inner surface of the first side plate 16 with a wide area. Can be locked to.

  When disassembling the packaging box 10 for disposal after opening, as shown in FIGS. 7 (a), 7 (b) and 7 (c) in sequence, the center portion of the bottom cover piece 32 is pushed in, and the breaking line for disassembly 36 is broken. Then, the closing of the bottom is easily released, the packaging box 10 can be folded thinly, and 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. Moreover, since the vicinity of the opening part 42 is reinforced with the auxiliary plate 68 in the assembled state, a good opening property can be stably realized. Moreover, after opening, it can be resealed reliably using the resealable piece 74, and operation to disassemble for disposal is also easy.

  Next, 2nd embodiment of the resealable packaging box of this invention is described based on FIGS. Here, the same components as those in the above embodiment are denoted by the same reference numerals and description thereof is omitted. As shown in FIG. 8, the packaging box 88 of this embodiment is a substantially rectangular parallelepiped box, and is formed by assembling a box forming piece 90 in which a single blank sheet such as cardboard is integrally punched. .

  FIG. 9 is a developed view of the box-forming piece 90 as seen from the back side, and is similar to the box-forming piece 12 of FIG. 2 as a whole, but is characterized in that the proximal end portion 68a of the auxiliary plate 68 is Instead of the point where the display piece 92 is provided on the inner side, the point where the auxiliary display part 94 is provided on the inner side of the side plate 14, and the disassembly breaking line 36 used when discarding, the second side The disassembly pressing part 96 is provided at the end of the face plate 20.

  The display piece 92 is provided on the inner side of the base end side portion 68 a of the auxiliary plate 68, separated by a fourth break line 98. The fourth crease line is formed in parallel with the crease line 70 at two positions, that is, the position of the crease line 72 on the auxiliary plate 68 and a position slightly away from the crease line 70 toward the crease line 72. A portion sandwiched between the break lines 98 becomes the display piece 92. Further, a knob 92 a is extended at the end of the display piece 92 opposite to the reseal piece 74, separated by a crease line 100. The crease line 100 is provided at a position substantially extending from the crease line 50 of the side plate 20. The display piece 92 is preliminarily printed with a product name, detailed information to be read by the user (for example, product handling instructions, usage precautions), and the like.

  The auxiliary display portion 94 is provided at a position near the center of the side plate 14 and the crease line 54 and surrounded by a substantially rectangular fifth break line 102, and overlaps the inside of the display piece 92 in an assembled state. It is the part to be glued. For example, in the process of packaging the product, information such as the product serial number and the expiration date is printed on the auxiliary display unit 94.

  The disassembling pressing part 96 forms the breaking line 104a inward from the both ends of the base end part of the lid piece 48 along the crease line 50, and the inner side ends of the breaking line 104a inside the second side face plate 20. Is formed by forming a continuous break line 104b, and a portion surrounded by the crease line 50 and the break line 104b becomes a disassembling pressing portion 96.

  Next, an example of a method for assembling the resealable packaging box 88 will be described. Here, the folding method in which the front surface of the box-forming piece 90 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. 10A, the crease line 70 is folded forward, the base end side portion 68a of the auxiliary plate 68 is overlapped with the second side plate 20, and the front end side portion 68b and the reseal piece 74 are attached. Overlap the side plate 18. Then, paste 78 is applied to a position close to the crease line 70 on the surface of the base end portion 68a (portion other than the display piece 92), paste 80 is applied to the center of the surface of the tip end portion 68b, and the resealed piece The glue 82 is applied to the center of the surface of 74. Further, the paste 106 is also applied to the center of the surface of the display piece 92 and a position near the second lid piece 44.

  Thereafter, as shown in FIG. 10B, the crease line 24 is forwardly folded, and the end of the back surface of the side plate 14 is glued to the surface of the base end side portion 68 b, and the back surface of the first side plate 16. Is glued to the surface of the tip end portion 68a, the back surface of the opening portion 42 is glued to the surface of the reseal piece 74, and the back surface of the auxiliary display portion 94 is glued to the surface of the display piece 92. . The box-forming piece 90 is shipped in this folded state.

  The process performed in a factory for storing and packaging products is substantially the same as that of the packaging box 10 described above. First, the crease lines 22, 24, 26, 70, 72 are each normally folded at 90 ° to form a rectangular cylinder. Then, as shown in FIGS. 4A, 4B, and 4C in order, one end of the cylinder is closed to form the bottom. At this time, the knob 92a of the display piece 92 is pushed to the bottom, is normally folded along the crease line 100, and is accommodated inside the box. Next, the product is put into the box from the other open end, and the open end of the cylinder is closed as shown in FIG. 5 (a) (b) (c) in order. A lid is formed. Further, an operation for printing the serial number, expiration date, etc. of the stored product on the surface of the auxiliary display unit 94 is performed. This completes the product packaging operation, and the assembled state shown in FIG. 8 is obtained.

  The operation of opening and resealing the assembled packaging box 88 is the same as that of the packaging box 10.

  When disassembling the packaging box 88 for disposal after opening, as shown in FIGS. 11 (a) and 11 (b) in order, the disassembling pressing portion 96 of the second side plate 20 is pushed and broken with a finger. When 32 and 48 are picked up and pulled up, the breaking line 104a is also broken, and as shown in FIG. 12 (a), the end portion of the cylindrical body closed at the bottom is opened.

  When the bottom portion is opened, when the knob 92a of the display piece 92 is picked with a finger and pulled away from the side plate 14, the two fourth break lines 98 are broken as shown in FIG. Is separated from the side plate 14. At this time, since the auxiliary display portion 94 of the side plate 14 is glued to the display piece 92, the fifth break line 102 is also broken almost simultaneously, and the auxiliary display portion 94 is also separated from the side plate 14. Since the display piece 92 in which the auxiliary display unit 94 is integrated describes important information such as the product name and expiration date of the product, for example, the product is taken out from the packaging box 88 and stored in a storage shelf or the like. In this case, it can be used as a display card for product identification. Since the box portion other than the display piece 92 is released from the closed bottom and can be folded thinly, it can be discarded in a compact form.

  As described above, the packaging box 88 can obtain the same effects as the packaging box 10 described above, and further, a convenient display piece 92 can be obtained by using the base end side portion 68a of the auxiliary plate 68. Can be obtained.

  Next, 3rd embodiment of the resealable packaging box of this invention is described based on FIGS.

A similar side flap 64 is extended to the other end of the side plate 114 and is separated from the side plate 114 by a crease line 66.

  A substantially rectangular auxiliary plate 124 is extended at an end portion on the side plate 110 side where the four side plates 110, 112, 114, 116 are connected, and is separated from the side plate 110 by a crease line 70. The length of the auxiliary plate 124 in the connecting direction is slightly shorter than that of the first side plate 116.

  The auxiliary plate 124 is an end portion in a direction perpendicular to the connecting direction, and a re-sealing piece 74 is extended to an end portion on the same side as the opening portion 42 of the first side plate 116, and the second breaking line 76 is separated from the auxiliary plate 124. The reseal piece 74 is provided at a position corresponding to the opening portion 42 of the first side plate 116, the width of the distal end portion is substantially the same as the length in the connecting direction of the first side plate 116, and the width of the base end portion is Both corners are slightly narrowed, and the size is such that the unsealed portion 42 is blocked as a whole.

  Further, the first lid piece 28 extends at the tip of the resealable piece 74 and is separated from the resealable piece 74 by the first crease line 30. The first crease line 30 is provided at a position substantially extending from the crease line 54 of the side plate 110, and the length of the first lid piece 28 in the extending direction is approximately the length of the connecting direction length of the side plates 110, 114. About 4/5.

  Next, an example of an assembly method of the resealable packaging box 106 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, as shown in FIG. 15A, the crease line 70 is normally folded, and the auxiliary plate 124 is overlaid on the side plate 110. Then, the glue 78 is applied to a position near the crease line 70 of the auxiliary plate 124, and the glue 82 is applied to the central portion of the surface of the reseal piece 74.

  Thereafter, as shown in FIG. 15B, the crease line 120 is folded forward, the end of the back surface of the first side plate 116 is glued to the surface of the auxiliary plate 124, and the back surface of the unsealed portion 42 is re-applied. The surface of the seal 74 is glued. The box-forming piece 108 is shipped in this folded state.

  The process performed in a factory for storing and packaging products is almost the same as that of the packaging box 10 described above. First, the crease lines 118, 120, 122, and 70 are each normally folded at 90 ° to form a rectangular cylinder. 4 (a), 4 (b), and 4 (c), one end of the cylinder is closed in the order shown in order, and the bottom is formed. However, in the case of this embodiment, since the second lid piece 44 is larger than the first lid piece 28, the second lid piece 44 is overlapped and glued on the outside of the first lid piece 28. . Next, the product is put into the box from the other open end, and the open end of the cylinder is closed in the order shown in FIGS. 5 (a), 5 (b) and 5 (c). , Forming a lid. However, in this embodiment, since the lid piece 48 is larger than the lid piece 32, the lid piece 48 is overlapped and glued on the outside of the lid piece 32. This completes the product packaging operation and the assembled state shown in FIG.

  Next, operations for opening and resealing the packaging box 106 will be described. When opening, the opening part 42 of the 1st side plate 116 is pushed and broken with a finger. At this time, since the peripheral portion of the opening portion 42 is reinforced by the auxiliary plate 124, the first side plate 116 is not easily deformed, and the first breaking line 40 can be easily broken. When the opening 42 is pushed and broken, the second breaking line 76 is also broken almost simultaneously, and the reseal piece 74 is separated from the auxiliary plate 68. The opening 42 is separated from the first side plate 116, but is not trashed because it is glued to the reseal piece 74. Then, when the reseal piece 74 and the first lid piece 28 are picked and pulled up, as shown in FIG. 16 (a), the end of the cylinder closed by the lid is opened, and the product inside It can be taken out.

  When the product is returned to the packaging box 106 after being opened and resealed, the resealable piece 74 is placed in the gap between the side flaps 52 and 60 and the first side plate 116 as shown in FIG. By inserting and engaging, the end of the cylinder is closed with a lid. The resealable piece 74 can be easily inserted because both corners on the side of the second broken line 76 that has been cut off are taken. The opening from which the opening 42 of the first side plate 116 has been removed is closed by the reseal piece 74. Since the opening part 42 is glued on the surface of the reseal piece 74, it does not dull and looks good, and does not hinder the reseal operation.

  The width of the resealable piece 74 is preferably set to be wide enough to fill the width of the first side plate 116, and the resealable piece 74 is stabilized by contacting the inner surface of the first side plate 116 with a large area. Can be locked to. Further, if a pair of cuts are provided from both ends of the first crease line 30, the cuts and the edges of the side flaps 52 and 60 are engaged with each other, so that the closed state can be more reliably maintained.

  When the packaging box 106 is disassembled for disposal after opening, the disassembling pressing portion 96 of the first side plate 116 is pushed with a finger as shown in FIGS. When 32 and 48 are picked up and pulled up, the breaking line 104a is also broken, the bottom is easily closed, the packaging box 106 can be folded thinly, and can be discarded in a compact form.

  As described above, the packaging box 106 can obtain the same effects as the packaging box 10 described above, and further, the size of the box-forming piece 108 is reduced and the number of places to be glued is reduced. The cost of the box can be reduced.

  In addition, the resealable packaging box of this invention is not limited to the said embodiment. For example, in the case of the packaging box 10 of the first embodiment, the first lid piece 28 and the first crease line 30 are provided at the end of the first side plate 16. Like the packaging box 106, you may provide these in the front-end | tip part of the reseal piece 74, and the same effect is obtained. Further, in the case of the packaging box 106 of the third embodiment, the first lid piece 28 and the first crease line 30 are provided at the tip of the reseal piece 74, but the packaging box of the first embodiment. As shown in FIG. 10, these may be provided at the end portion of the first side plate 116, and the same effect can be obtained.

  The form of the auxiliary plate can be freely changed as long as the portion where the resealing piece is extended overlaps the side plate having the opening portion and can reinforce the vicinity of the opening portion. For example, the auxiliary plate of the packaging box 88 of the second embodiment is in a form that can be used as a display card by separating a part, but in addition, a part of the auxiliary plate functions as a partition inside the box. You may make it the form to do.

  The size of the box, the material, the shape of each member, and the form of the break line (perforation, zipper line, etc.) can be changed as appropriate. Further, not only the lid part side but also the bottom part side may be provided with the above-mentioned resealing pieces and opening parts so that both sides of the cylindrical body can be opened and resealed.
