  Hereinafter, one embodiment of this invention is described based on a drawing. FIG. 1 shows a packaging box 10 according to an embodiment of the present invention. The packaging box 10 is formed by assembling a box forming piece 12 shown in FIG.

  The box forming piece 12 is formed by punching out one blank sheet such as cardboard, and the first side plate 14, the front plate 16, the second side plate 18, and the back plate 20 are sequentially connected. Further, a glued piece 22 that is glued to the inside of the first side plate 14 in an assembled state is connected to the side of the back plate 20. The first side plate 14, the front plate 16, the second side plate 18, the back plate 20, and the glued piece 22 are separated by crease lines 24, 26, 28, and 30, respectively.

  A substantially trapezoidal first side flap 32 extends from one end of the first side plate 14 and is separated from the end of the first side plate 14 by a crease line 34. The extending length of the first side flap 32 is about ½ of the width (length in the connecting direction) of the front plate 16, and a slot-like slit 38 is slanted at a position near the outer lid piece 36 described later. Is formed.

  A substantially trapezoidal flap 40 extends from the other end of the first side plate 14 and is separated from the first side plate 14 by a crease line 42.

  At one end portion of the front plate 16 on the first side flap 32 side, an isosceles trapezoidal outer lid piece 36 is extended so that the width of the base end portion is equal to the width of the front plate 16 and the width of the distal end portion is slightly narrow. The first crease line 44 is separated from the front plate 16. The extending length of the outer lid piece 36 is substantially the same as the width (length in the connecting direction) of the first side plate 14. Further, the outer lid piece 36 is provided with a pair of reseal perforations 46 for partitioning the base end side corners 36a and other portions in a substantially fan shape.

  A pair of opening break lines 48 are formed inward from both ends of the first crease line 42, and a pair of opening break lines 48 are formed on the front plate 16 from the inner tip of each opening break line 48. A character-shaped opening breaking line 50 is formed, and an opening portion 52 surrounded by the central portion of the first crease line 44 and the opening breaking line 50 is provided. The opening portion 52 is large enough to be pushed in with a thumb.

  A flap 54 having substantially the same shape as the outer lid piece 36 is extended to the other end portion of the front plate 16, and is separated from the front plate 16 by a crease line 56.

  A pair of break lines 58 are formed inward from both ends of the crease line 56, respectively, and a U-shaped break line 60 starting from each inner front end portion of the break line 58 is formed on the front plate 16. Is formed, and a pressing portion 62 surrounded by the center portion of the crease line 56 and the breaking line 50 is provided. The pressing part 62 is large enough to be pressed with a finger.

  A substantially trapezoidal second side flap 64 extends from one end of the second side plate 18 on the outer lid piece 36 side, and is separated from the end of the second side plate 18 by a crease line 66. An oblong slit 68 is formed obliquely at a position close to 36. The shape of the second side flap 64 (including the slit 68) is substantially line-symmetric with the shape of the first side flap 32 (including the slit 38) with the outer lid piece 36 interposed therebetween.

  A flap 70 having substantially the same shape as the flap 40 is extended to the other end of the second side plate 18, and is separated from the second side plate 18 by a crease line 72.

  At one end portion of the back plate 20 on the second side flap 64 side, an isoptric trapezoidal inner lid piece 74 is provided so that the width of the base end portion is equal to the width of the back plate 20 and the width of the tip portion is slightly narrow. The back plate 20 is separated by a crease line 76. As will be described in detail later, the inner lid piece 74 is smaller than the outer lid piece 36 and can be inserted into the slits 38 and 68 when the tip end side corners 74a are resealed after being assembled and opened in the packaging box 10. It is a simple shape.

  A flap 78 having substantially the same shape as the inner lid piece 74 is extended to the other end portion of the second side plate 18, and is separated from the flat plate 20 by a crease line 80.

  Next, a method for assembling the box forming piece 12 will be described with reference to FIGS. Here, FIG. 2 is a view of the box-forming piece 12 from the back side. Hereinafter, the folding method in which the front side of the box-forming piece 12 is convex is reversed, and the folding method in which the back side is concave is reversed. This is called folding.

  First, paste (not shown) is applied to the surface of the glued piece 22, the crease line 28 is normally folded, the crease line 24 is further folded, and the surface of the glued piece 22 is glued to the back surface of the first side plate 14. .

  Next, in a factory or the like where products are stored and packaged, the crease lines 24, 26, 28, and 30 are normally folded at 90 degrees to form a rectangular cylindrical body. And one edge part used as the bottom part of a cylindrical body is closed. First, the flaps 40 and 70 are folded forward at 90 degrees along the crease lines 42 and 72, respectively, paste (not shown) is applied to the position near the crease line 80 from the center of the surface of the flap 78, and the flap 78 is moved along the crease line 80 to 90 degrees. Fold it forward every time. Then, the flap 54 is normally folded at 90 degrees along the crease line 54, and the front surface of the flap 78 is glued to the back surface of the flap 54. Next, a tubular product or the like is accommodated inside from the open end of the tubular body.

  In order to close the open end when a product or the like is accommodated, first, the first and second side flaps 32 and 64 are first folded at 90 degrees along the crease lines 34 and 66, respectively, as shown in FIG. Next, as shown in FIG. 4, the glue 82 is applied to a position away from the front end side corners 74 a on the surface of the inner lid piece 74, and the inner lid piece 74 is folded at 90 degrees along the crease line 76. In this state, the leading end side corners 74 a of the inner lid piece 74 overlap above the slits 38 and 68 formed in the first and second side flaps 32 and 64. Then, the outer lid piece 36 is normally folded at 90 degrees along the crease line 44, and the surface of the inner lid piece 74 is glued to the back surface of the outer lid piece 36. The base end side corners 36a of the outer lid piece 36 overlap the tip side corners 74a of the inner lid piece 74 and cover the slits 38 and 68 as shown in FIG. With the above operation, the packaging of the packaging box 10 is completed.

  Next, the operation of opening the packaging box 10 and the operation of resealing will be described in order. When opening, the opening portion 52 of the front plate 16 is pushed with a finger to break the U-shaped opening breaking line 50, and the outer lid piece 36 and the inner lid piece 74 are picked up and pulled up to break the opening breaking line. 48 is broken. And the 1st and 2nd side flaps 32 and 64 are pulled up, the edge part of a cylindrical body is open | released, and the goods inside are taken out. As shown in FIG. 5, in this state, since the outer lid piece 36, the inner lid piece 74, and the opening portion 52 are integrally connected to the back plate 20, no dust is separated from the main body.

  When the product is returned to the packaging box 10 and resealed, the first and second side flaps 32 and 64 are folded back at 90 degrees and returned to the original position, as shown in FIG. The piece 36 is folded forward at 90 degrees and returned to its original position.

  Further, when the position of the center of the outer lid piece 36 slightly close to the opening portion 52 (for example, point P in the figure) is pushed down with a finger, the first and second side flaps 32 and 64 are pushed downward by the inner lid piece 74. The both end portions 74a of the inner lid piece 74 are inserted into the slits 38 and 68 and engaged with each other. At this time, the distal end side corner portions 74 a are not glued to the outer lid piece 36, and the outer lid piece 36 bends downward, whereby the distal end side corner portions 74 a become the proximal end corner portions 36 a of the outer piece 36. Therefore, it can be smoothly inserted into the slit 38 and the slit 68. In addition, the outer lid piece 36 is provided with a pair of perforations 46 for resealing, and the outer lid piece 36 bends in an ideal manner. Even if it deviates somewhat, it can be inserted well.

  When the operation of pushing down the outer lid piece 36 with a finger is stopped, the state in which the inner lid piece 74 overlaps the first and second side flaps 32 and 64 is maintained, and the end of the cylindrical body is closed.

  The lid portion (flaps 40, 54, 70, 78) that closes the opening on the opposite side is not opened when the packaging box 10 is used, but is opened when it is disassembled and discarded after use. The disassembling operation is simple. First, the pressing portion 62 of the front plate 16 is pushed with a finger to break the U-shaped opening breaking line 60, and the flaps 54, 78 are picked up and pulled up to open the opening breaking line 58. Break and fold along the crease line. If folded, it is not bulky and is easy to discard.

  As described above, the packaging box 10 of this embodiment is easy to assemble with a simple structure, easy to open, and can be resealed after opening without discomfort. Also, the resealing operation is simple, and in the case of the assembly paper box of Patent Document 2, two actions are necessary (because there are two lid pieces), and this packaging box 10 can be resealed with one action. . In addition, since the engaging portion between the front end side corners 74a of the inner lid piece 74 and the slits 38 and 68 is covered with the outer lid piece 36 after resealing, a dustproof effect that makes it difficult for dust and dirt to enter inside is provided. can get.

  Moreover, the existing sealing end carton packaging device can be used, and the packaging workability is good.

  In addition, the packaging box of this invention is not limited to the said embodiment. For example, the reseal perforation 46 provided on the outer lid piece 36 controls the way the outer lid piece 36 bends during the reseal operation. For example, the reseal perforation 46 is replaced with a crease line for resealing. Also good. Further, the reseal perforation 46 itself may be omitted if necessary. Moreover, the opening part 52 can be abbreviate | omitted as needed, and it is good to extend the inside of the two breaking break lines 48, and to make it continuous, for example in that case.

  The size of the box, the material, the shape of each part, etc. can be changed as appropriate. In particular, the shape of the engagement hole of the front end side corners of the inner lid piece and the first and second side flaps is triangular, semi-circular, etc. It can be changed to adjust the strength of engagement.

  The terms first side plate, front plate, second side plate, and back plate, which are the sides of the box, are defined to specify the structure of the packaging box of the present invention. The front is free. For example, the product name may be printed and displayed on the back plate so as to be conspicuous, and the back plate may be arranged facing the front when displayed at the storefront.
