Description

  The present invention relates to a packaging box with a reseal function that can be resealed after opening a sealed end type lid.

  Conventionally, as disclosed in, for example, Patent Document 1, it is composed of a single box-forming piece, and the box-forming piece includes four side plates connected in a row and each edge portion of the four side plates. The pair of side flaps, the inner lid and the outer lid overlap each other in the assembled state before opening, and the outer lid is glued to the surface of the inner lid. There has been a packaging box in which a sealed end canopy is formed. This packaging box is provided with an opening portion continuous with the outer lid and a perforation for separating the opening portion and the outer lid from the side plate at the end of the side plate on which the outer lid is extended. When this is done, the lid can be opened and closed by breaking the perforation.

  Furthermore, in order to make the opened lid part resealable, the box-forming piece is provided with an extension flap extending on the side edge part of the outer lid, and a side edge part perpendicular to the extension direction of the extension flap. And an extended insertion piece. In the assembled state before opening, the extension flap is fixed to the back surface of the outer lid, and the insertion piece is disposed so as to overlap the inner surface of the side plate on which the inner lid is extended. Then, after the perforation is cut and opened, the side flap, the inner lid and the first lid piece are sequentially overlapped in the re-sealed state, and the insertion piece is the inner surface of the side plate on which the inner lid is extended. It is inserted and locked to the side, and the lid is kept closed.

  For example, when a medicine that is packaged and distributed in a packaging box is delivered to a medical institution such as a hospital or a dispensing pharmacy, it is often stored side by side on a storage shelf by type in a state of being contained in the packaging box. Then, the manager in charge such as a pharmacist must open the next new box (unopened box) after the unopened medicine is lost. Therefore, in order to prevent a new box from being opened even though the opened box remains, it is required that the pharmaceutical packaging box can accurately determine whether or not it has been opened.

  However, the packaging box with the reseal function of Patent Document 1 has a difference in whether the perforation is separated or not when comparing the resealed state and the state before opening, but there is no great difference in appearance. It is difficult to determine at a glance whether the box has been opened. Moreover, this packaging box with a reseal function is formed from a single box-forming piece (see FIG. 3 of Patent Document 1), but an extension flap and an insertion piece are added. Since the area becomes larger than before, and the extension flap and the insertion piece have an irregular outer shape protruding sideways, it is difficult to efficiently punch out from a large blank sheet.

  The present invention has been made in view of the above-mentioned background art, is easy to reseal, and can easily determine at a glance whether it is resealed or unopened. The purpose is to provide.

In the present invention, a rectangular tube formed by a plurality of side plates and an end side of a first side plate which is one of the plurality of side plates are extended via a first crease line. A first lid piece; a second lid piece extending from an end of the second side plate facing the first side plate in the plurality of side plates; and the plurality of side plates. Of the first and second side plates, the side flaps extending respectively on the end sides of the two side plates, the inner side of the first side plate, the first fold line An opening part continuous with the first lid piece through the opening, and a breaking line for opening for separating the first lid piece and the opening part from the first side plate at the time of opening, before opening In the assembled state, the first and second lid pieces overlap the upper side of the side flap, and the first and second lid pieces are glued together to form a lid portion. A packaging box sealing end type formed,
Inside the first lid piece, a crease line for resealing the first lid piece into a distal end region and a proximal end region, and the crease line for resealing from both ends of the crease line for reseal A pair of incisions extending inward so as to overlap with each other, and two side flaps are provided with engaging portions each having a shape capable of entering and engaging in the notches of the first lid piece,
After the opening breaking line is cut off and opened, the tip side region of the first lid piece and the second lid piece overlap the upper side of the side flap, The re-sealing crease line of one lid piece is bent so that the proximal end region and the opening portion extend toward the inside of the cylindrical body, and the engaging portion of the side flap is the first lid piece. A packaging box with a reseal function in which the distal end side region of the first lid piece and the second lid piece are held in a closed state.

  A side end portion of the side flap on the side close to the base end side region of the first lid piece is obliquely chamfered, and the engaging portion is provided in the chamfered portion. Further, in the assembled state before opening, the second lid piece does not overlap the proximal end side region, the re-sealing crease line and the notch of the first lid piece, but below the distal end side region. It is glued on the side. Alternatively, in the assembled state before opening, the second lid piece overlaps the upper side of the first lid piece and is glued to the tip side region of the first lid piece. Moreover, it is preferable that it is the structure formed by one box body formation piece.

  The packaging box with a resealing function of the present invention can be easily and smoothly resealed after the breaking line for opening is cut and opened. In addition, in the re-sealed state, the location where the opening portion was present before opening is opened on the first side plate, and the opening portion is arranged at a position slightly away from the inside, so the opened state And the state before opening is large, and it can be easily discriminated at a glance whether or not the box has been opened.

  Moreover, the packaging box with a reseal function of the present invention does not increase the area and outer shape of the box-forming piece as compared with an ordinary sealed end type packaging box having no reseal function. Therefore, the box-forming piece can be manufactured by punching efficiently from a large blank sheet in the same manner as an ordinary sealed end type packaging box.

  Hereinafter, 1st embodiment of the packaging box with a reseal function of this invention is described based on FIGS. 1-3. As shown in FIG. 1A, the packaging box 10 with a reseal function of this embodiment is a rectangular parallelepiped box body in which both ends of a cylindrical body 12 are closed by a seal end type lid portion 14 and a bottom portion 16. is there. The packaging box 10 with the reseal function 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, and 26 have the same length in the connecting width direction, and the length in the connecting direction is substantially equal to each other because the side plates 20 and 24 are short. Long and almost equal to each other.

  A gluing piece 28 is shortly connected to the end of the side plate 26 in the connecting direction. The gluing piece 28 is a portion that is glued to the end of the side plate 20 at the time of assembly in order to form the cylindrical body 12. The four side plates 20, 22, 24, 26 and the glue piece 28 are divided by crease lines 30, 32, 34, 36, respectively. Hereinafter, the side plate 22 is referred to as a first side plate 22, and the side plate 26 is referred to as a second side plate 26.

  Each side plate 20, 22, 24, 26 has a member for forming the lid portion 14 extending on the upper end side in FIG. 2A, and the bottom portion 16 is formed on the lower end side. Each member for extending is provided.

  A trapezoidal side flap 38 extends from the upper side edge of the side plate 20 and is separated from the side plate 20 by a crease line 40. The side flap 38 has an extension length of about 2/5 of the connection direction length of the first and second side plates 22 and 26, and the side end portion on the first lid piece 46 side described later is chamfered obliquely. An engaging portion 38a is provided in the middle of the chamfered portion. Further, a substantially rectangular side flap 42 is extended on the lower side edge of the side plate 20, and is separated from the side plate 20 by a crease line 44.

  A substantially rectangular first lid piece 46 extends from the upper end side of the first side plate 22 and is separated from the first side plate 22 by a first crease line 48. The extension length of the first lid piece 46 is the same as or slightly shorter than the length of the side plates 20 and 24 in the connecting direction. Then, a reseal crease line 50 substantially parallel to the first crease line 48 is provided at a position near the first crease line 48 inside the first lid piece 46, and the first lid piece 46 is at the base end. It is divided into a side region 46a and a tip side region 46b. The distance between the reseal break line 50 and the first crease line 48 is about 1/6 of the length of the side plates 20 and 24 in the connecting direction. Further, a pair of cuts 52 extending inward from both ends of the resealing crease line 50 so as to overlap the resealing crease line 50 are provided.

  A U-shaped or V-shaped opening breaking line 54 that connects both ends of the first crease line 48 is provided at the end of the first side plate 22 on the first lid piece 46 side. The part surrounded by the breaking line 54 for opening and the first crease line 48 becomes an opening part 56 that is pushed and broken by a finger when the packaging box 10 with the reseal function is opened.

  A substantially rectangular outer bottom piece 58 extends from the lower side edge of the first side plate 22 and is separated from the first side plate 22 by a crease line 60. The extension length of the outer bottom piece 58 is the same as or slightly shorter than the length of the side plates 20 and 24 in the connecting direction.

  A trapezoidal side flap 62 extends from the upper side edge of the side plate 24 and is separated from the side plate 24 by a crease line 64. The side flap 62 has a shape symmetrical with the side flap 38 about the first lid piece 46, and is provided with an engaging portion 62a corresponding to the engaging portion 38a. Further, a substantially rectangular side flap 66 is extended at the lower end of the side plate 24 and is separated from the side plate 24 by a crease line 68.

  A substantially rectangular second lid piece 70 is extended on the upper side edge of the second side plate 26, and is separated from the second side plate 26 by a crease line 72. The extension length of the second lid piece 70 is about 3/4 of the length in the connecting direction of the side plates 20 and 24. A substantially rectangular inner bottom piece 74 is extended on the lower side edge of the second side plate 26 and separated from the second side plate 26 by a crease line 76. The extension length of the inner bottom piece 74 is about 3/4 of the length of the side plates 20 and 24 in the connecting direction.

  Next, an example of the assembly method of the packaging box 10 with a reseal function is demonstrated. Here, regarding the folding method of each crease line and break line of the box-forming piece 18 shown in FIG. 2, the folding method in which the front surface 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 34 of the box-forming piece 18 is folded forward so that the glue piece 28 and the second side plate 26 overlap the first side plate 22 and the side plate 24. Then, after applying glue on the surface of the glue piece 28, the crease line 30 is normally folded and the side plate 20 is overlaid on the glue piece 28, and the back surface of the end of the side plate 20 is glued to the glue piece 28. The box forming piece 18 is shipped from the manufacturing factory of the packaging box 10 with the reseal function in this folded state.

  Next, in a factory or the like for packaging the contents, the crease lines 30, 32, 34, and 36 of the box-shaped piece 18 are each normally folded at 90 degrees to form a rectangular shape composed of side plates 20, 22, 24, and 26. A cylindrical body 12 is formed. Then, the side flaps 42 and 66 are each normally folded at 90 degrees along the crease lines 44 and 68, and the inner bottom piece 74 is normally folded at 90 degrees along the crease lines 76 and overlapped with the side flaps 42 and 66. Then, after applying glue on the surface of the inner bottom piece 74, the outer bottom piece 58 is forwardly folded at 90 degrees along the crease line 60 and overlapped with the inner bottom piece 74, and the back surface of the outer bottom piece 58 is glued to the inner bottom piece 74. Thus, one end of the cylindrical body 12 is closed by the bottom end 16 of the seal end type, and the contents are put in from the open end on the opposite side.

  After the contents are put in, the lid portion 14 is formed. First, the side flaps 38 and 62 are each normally folded at 90 degrees along the crease lines 40 and 64, the crease line 72 is normally folded at 90 degrees, and the second lid piece 70 is overlapped on the side flaps 38 and 62. Then, after applying the glue 78 to the substantially central portion of the surface of the second lid piece 70, the first lid piece 46 is forwardly folded at 90 degrees along the first crease line 48 and overlapped on the second lid piece 70. The back surface of the distal end side region 46 b of the first lid piece 46 is glued to the second lid piece 70. As a result, the other end portion of the cylindrical body 12 is also closed by the seal end type lid portion 14, and the assembled state shown in FIGS. 1A and 1B is obtained.

  As shown in FIG. 1 (b), in the assembled state, the second lid piece 70 is disposed below the first lid piece 46, and the proximal end side region 46a of the first lid piece 46 is resealed. It does not overlap with the crease line 50 and the notch 52 but overlaps with the tip end region 46a. Two notches 52 are disposed in the vicinity of the engaging portions 38a and 62b of the side flaps 38 and 62, respectively.

  When opening the packaging box 10 with the reseal function, the opening portion 56 is pushed with a finger to break the opening breaking line 54, and the opening portion 56 and the first lid piece 46 are separated from the first side plate 22. As a result, the first and second lid pieces 46 and 70 that are glued to each other can be opened and closed, the first and second lid pieces 46 and 70 are pulled up, and the side flaps 38 and 62 are further moved. When pulled up, as shown in FIG. 3A, the lid portion 14 is widely opened, and the contents contained therein can be taken out.

  When resealing after opening the packaging box 10 with the reseal function, as shown in FIG. 3 (b), first fold the crease lines 40 and 64 at 90 degrees and tilt the side flaps 38 and 62. . Then, the crease line 50 for resealing is bent in the forward folding direction, the crease line 72 is forwardly folded at 90 degrees, and the proximal end portion 46a of the opening portion 56 and the first lid piece 46 is made to be the first side plate. 22, the front end side region 46 b of the first lid piece 46 and the second lid piece 70 are overlapped with the side flaps 38 and 62 while being inserted into a gap surrounded by the side flaps 38 and 62. Then, the engaging portions 38a and 62a of the side flaps 38 and 62 smoothly enter the two notches 52 of the first lid piece 46 and engage with each other, and the lid portion 14 is held in a closed state. The resealed state shown in 3 (c) is obtained.

  In the resealed state, the crease line 50 for resealing of the first lid piece 46 is bent so that the proximal end region 46a and the opening 56 extend toward the inside of the cylindrical body 12, and the first side plate 22 The place where the opening part 56 existed before opening is opened, and the opening part 56 is arranged at a position slightly away from the inside. Accordingly, when the appearances of the resealed state and the state before opening are compared, a particularly large difference occurs when viewed from the first side plate 22 side.

  As described above, the packaging box 10 with a reseal function can be easily and smoothly resealed after the breaking line 54 for unsealing is cut and opened. Further, since the appearance when viewed from the side of the first side plate 22 is greatly different between the re-sealed state and the state before opening, it can be easily determined at a glance whether the box is already opened. it can.

  Further, the packaging box 10 with a reseal function does not have a large area or outer shape of the box-forming piece as compared with an ordinary sealed end type packaging box that does not have a reseal function. Accordingly, the box-forming piece 18 can be efficiently punched from a large blank sheet in the same manner as an ordinary sealed end type packaging box.

  Next, 2nd embodiment of the packaging box with a reseal function 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. 4A, the packaging box 80 with a reseal function of this embodiment is a rectangular parallelepiped box body in which both ends of the cylindrical body 12 are closed by a seal end type lid portion 14 and a bottom portion 16. Yes, the shape and size are almost the same as those of the packaging box 10 with the reseal function. The packaging box 80 with the reseal function is formed by assembling a single box forming piece 82 made of cardboard or the like.

  As shown in FIG. 5, the configuration of the box-forming piece 82 is different from the box-forming piece 18 in that a new first lid piece 84 and an inner The bottom piece 86 is extended to each other, and the new second lid piece 88 and the outer bottom piece 90 are respectively extended to the two end sides of the second side plate 26.

  The first lid piece 84 has a substantially rectangular shape, and the extension length is set to about 3/4 of the length of the side plates 20 and 24 in the connecting direction (than the first lid piece 46 described above). A little short). The first lid piece 84 is provided with the re-sealing crease line 50 and the notch 52 on the inner side, and is divided into a proximal end side region 84a and a distal end side portion 84b by the resealing crease line 50. The inner bottom piece 86 has a substantially rectangular shape, and the extension length is set to about 3/4 of the length of the side plates 20 and 24 in the connecting direction (slightly shorter than the outer bottom piece 58).

  The second lid piece 88 has a substantially rectangular shape, and its extension length is set to be the same as or slightly shorter than the length of the side plates 20 and 24 in the connecting direction (slightly longer than the second lid piece 70). An arcuate cutout 88a is provided at the center of the leading edge. The outer bottom piece 90 has a substantially rectangular shape, and the extension length is set to be the same as or slightly shorter than the length of the side plates 20 and 24 in the connecting direction (a little shorter than the inner bottom piece 74).

  The method for assembling the packaging box 80 with the reseal function is substantially the same as the packaging box 10 with the reseal function described above, but the procedure for assembling the bottom 16 and the lid 14 after forming the rectangular cylinder 12 is as follows. A little change. When assembling the bottom portion 16, the side flaps 42, 66 are each normally folded at 90 degrees along the crease lines 44, 68, and the inner bottom piece 86 is normally folded at 90 degrees along the crease lines 60, and overlapped with the side flaps 42, 66. Then, after applying glue on the surface of the inner bottom piece 86, the outer bottom piece 90 is forwardly folded at 90 degrees along the crease line 76 and overlapped with the inner bottom piece 86, and the back surface of the outer bottom piece 90 is glued to the inner bottom piece 86. Thus, one end of the cylindrical body 12 is closed by the bottom end 16 of the seal end type, and the contents are put in from the open end on the opposite side.

  When the lid 14 is assembled after the contents are put, first, the side flaps 38 and 62 are each normally folded at 90 degrees along the crease lines 40 and 64, and the first lid piece 84 is folded along the first crease line 48. Fold it forward 90 degrees and place it on the side flaps 38 and 62. And after apply | coating the glue 78 to the surface of the front end side area | region 84b of the 1st cover piece 84, the 2nd cover piece 88 is forward-folded 90 degree | times with the crease line 72, and it overlaps on the 1st cover piece 84, The back surface of the second lid piece 88 is glued to the distal end side region 84 b of the first lid piece 84. As a result, the other end portion of the cylindrical body 12 is also closed by the seal end type lid portion 14, and the assembled state shown in FIGS. 4A and 4B is obtained.

  As shown in FIG. 4B, in the assembled state, the second lid piece 88 is disposed on the upper side of the first lid piece 46, and the proximal end side region 84a and the distal end side region of the first lid piece 84 are arranged. 84b (including the resealing crease line 50 and the cut 52). Two notches 52 are disposed in the vicinity of the engaging portions 38a and 62b of the side flaps 38 and 62, respectively.

  When opening the packaging box 80 with the reseal function, it is the same as the case of the packaging box 10 with the reseal function described above, and by opening the lid portion 14 widely as shown in FIG. The contents can be taken out.

  Further, when the packaging box 80 with the reseal function is opened and then resealed, it is substantially the same as the packaging box 10 with the reseal function as shown in FIGS. 6B and 6C in order. In the case of the packaging box 80 with the reseal function, the reseal crease line 50 of the first lid piece 84 is hidden under the second lid piece 88. The finger may be put on the central portion of the base end side region 84a exposed through the notch 88a of the second lid piece 88.

  The resealed state of the packaging box 80 with the reseal function is different from the above-described packaging box 10 with the reseal function in that the second lid piece 88 is located above the first lid piece 84. The rest of the crease line 50 of the first lid piece 84 is bent so that the proximal side region 84a and the opening portion 56 extend toward the inside of the cylindrical body 12, and the first side plate 22 The place where the opening part 56 existed before opening is opened, and the opening part 56 is arranged at a position slightly away from the inside. Accordingly, when the appearances of the resealed state and the state before opening are compared, a particularly large difference occurs when viewed from the first side plate 22 side.

  Thus, also in the packaging box 80 with a reseal function, the same outstanding effect as the said packaging box 10 with a reseal function is acquired. In addition, since the crease line 50 and the notch 52 for resealing the first lid piece 84 are hidden under the second lid piece 88 in the assembled state and the resealed state before opening, packaging with a reseal function There is also an advantage that the appearance when the box 80 is viewed from the lid 14 side is slightly improved.

  In addition, the packaging box with a reseal function of this invention is not limited to the said embodiment. For example, the shape of the engaging portions 38a, 60a of the side flaps 38, 60 and the vicinity thereof is such that the engaging portions 38a, 60a are smoothly inserted into the cut 52 of the first lid piece 46 or 84 when resealing. It shows an example of a shape that can be engaged and can be engaged, and the shape of the engaging portion may be appropriately adjusted and changed according to the thickness and material of the base material of the box-forming piece.

  In addition, the configuration of the bottom portion is not limited to the structure of the bottom portion 16 described above, and can be freely changed. For example, the same structure as the lid portion may be used.
