Description

本考案は、外箱の中に、バイアル等の収容物を保護する緩衝用仕切りが設けられた緩衝用仕切り付き包装箱に関する。 The present invention relates to a packaging box with a cushioning partition in which a cushioning partition for protecting contents such as vials is provided in the outer box.

従来、例えば本願出願人による特許文献１に開示されているように、ワンタッチ型の底蓋部を備えた直方体形状の外箱と、外箱の中に配置される緩衝用仕切りとが一体に設けられた緩衝用仕切り付き包装箱があった。この緩衝用仕切り付き包装箱は、一枚に箱体形成片から成り、緩衝用仕切りが、底蓋部を構成する第二の底蓋片の端部に連続している。また、外箱の胴部（４つの側面板で成る筒体）を形成するための糊付け片にストッパ片が付設され、緩衝用仕切りの上端部をストッパ片の段差部に係合させることによって、立体的にした緩衝用仕切りが折り畳み状態に戻ろうとする動作を阻止する構造になっている。 Conventionally, for example, as disclosed in Patent Document 1 by the applicant of the present application, a rectangular parallelepiped outer box provided with a one-touch type bottom lid and a cushioning partition arranged in the outer box are integrally provided. There was a packaging box with a partition for cushioning. The packaging box with a cushioning partition is composed of a box body forming piece, and the cushioning partition is continuous with the end portion of the second bottom lid piece constituting the bottom lid portion. Further, a stopper piece is attached to the glued piece for forming the body of the outer box (a cylinder composed of four side plates), and the upper end of the cushioning partition is engaged with the stepped portion of the stopper piece. The three-dimensional cushioning partition has a structure that prevents the movement of returning to the folded state.

また、特許文献２にも、直方体形状の外箱と、外箱の中に配置される緩衝用仕切りとが一体に設けられた薬容器包装用紙箱が開示されている。この薬容器包装用紙箱は、一枚の箱体形成片から成り、緩衝用仕切りが、外箱の胴部を形成するための糊付け板となる内側背板の端部に連続している。また、内側背面と離れて対向する正面板の端部に支持板押え板が延設され、組み立て状態で、支持板押え板が正面板の内面に重なり、支持板押え板に設けた差込舌片を緩衝用仕切りの上端角部（支持板の端部）のスリットに差し込んで係合させることによって、立体的にした緩衝用仕切りが折り畳み状態に戻ろうとする動作を阻止する構造になっている。 Further, Patent Document 2 also discloses a medicine container wrapping paper box in which a rectangular parallelepiped outer box and a cushioning partition arranged in the outer box are integrally provided. This medicine container wrapping paper box is composed of a single box body forming piece, and a cushioning partition is continuous with the end of an inner back plate which is a gluing plate for forming the body of the outer box. In addition, the support plate presser plate is extended to the end of the front plate facing away from the inner back surface, and in the assembled state, the support plate presser plate overlaps the inner surface of the front plate, and the insertion tongue provided on the support plate presser plate. By inserting the piece into the slit at the upper end corner (end of the support plate) of the cushioning partition and engaging it, the structure is such that the three-dimensional cushioning partition prevents the movement of returning to the folded state. ..

特許文献１の緩衝用仕切り付き包装箱は、緩衝用仕切りがワンタッチ型の底蓋部（第二の底蓋片）の端部に連続している構造なので、組み立てる時、折り畳まれた箱体形成片を立体的にして底蓋部を形成するのが意外に難しく、作業者が不慣れだと時間が掛かってしまう。また、緩衝用仕切りを立体的にした後、さらに、ストッパ片を緩衝用仕切りの上端部に係合させる動作を行う必要がある。また、使用後に廃棄する時、箱体をコンパクトに折り畳めるように解体するのが簡単ではない。 The packaging box with a cushioning partition of Patent Document 1 has a structure in which the cushioning partition is continuous with the end of the one-touch type bottom lid portion (second bottom lid piece), so that the box body is folded when assembled. It is surprisingly difficult to make the piece three-dimensional to form the bottom lid, and it takes time if the worker is unfamiliar with it. Further, after making the cushioning partition three-dimensional, it is necessary to further perform an operation of engaging the stopper piece with the upper end portion of the cushioning partition. Also, when disposing of the box after use, it is not easy to disassemble the box so that it can be folded compactly.

特許文献２の薬容器包装用紙箱の場合、折り畳み状態の箱体形成片を立体的にして底蓋部を形成する動作は容易であるが、緩衝用仕切りを立体的にした後、さらに支持板押え板の差込舌片を緩衝用仕切りの上端角部（支持板の端部）のスリットに差し込んで係合させる動作を行う必要があり手間が掛かる。 In the case of the medicine container wrapping paper box of Patent Document 2, the operation of forming the bottom lid portion by making the folded box body forming piece three-dimensional is easy, but after making the cushioning partition three-dimensional, the support plate is further formed. It is necessary to insert the insertion tongue piece of the presser plate into the slit at the upper end corner (end of the support plate) of the cushioning partition and engage it, which is troublesome.

本考案は、上記背景技術に鑑みて成されたものであり、緩衝用仕切りが折り畳み状態に戻ろうとする動作を阻止する構造を備え、且つ組み立てやすくシンプルな構造の緩衝用仕切り付き包装箱を提供することを目的とする。 The present invention has been made in view of the above background technology, and provides a packaging box with a cushioning partition having a structure that prevents the cushioning partition from returning to the folded state and having a simple structure that is easy to assemble. The purpose is to do.

第一の側面板２２の蓋側の端部には、略長方形の蓋片４０が延設され、第一の折罫線４２で第一の側面板２２と区切られている。蓋片４０の延出長さは、第二及び第四の側面板２４，２８の連接方向長さとほぼ同じである。さらに、蓋片４０の先端部には、差し込み片４４が延設され、折罫線４６で蓋片４０と区切られている。差し込み片４４は、先端側の中央部が円弧状に切り欠かれ、先端側の両角部が丸く面取りされている。 A substantially rectangular lid piece 40 is extended at the end of the first side plate 22 on the lid side, and is separated from the first side plate 22 by a first fold ruled line 42. The extending length of the lid piece 40 is substantially the same as the connecting direction length of the second and fourth side plates 24 and 28. Further, an insertion piece 44 is extended at the tip of the lid piece 40, and is separated from the lid piece 40 by a fold ruled line 46. The insertion piece 44 has a central portion on the distal end side cut out in an arc shape, and both corner portions on the distal end side are chamfered in a round shape.

第一の側面板２２の底側の端部には、台形状の第一の底片４８が延設され、折罫線５０で第一の側面板２２と区切られている。第一の底片５８の延出長さは、第二及び第四の側面板２４，２８の連接方向長さの約2/5で、内側に設けた２つの補助折罫線５２によって、先端側の両角部が略三角形に区切られている。 At the bottom end of the first side plate 22, a trapezoidal first bottom piece 48 is extended and separated from the first side plate 22 by a fold ruled line 50. The extending length of the first bottom piece 58 is about 2/5 of the length in the connecting direction of the second and fourth side plates 24 and 28, and the tip side is provided by the two auxiliary fold ruled lines 52 provided inside. Both corners are divided into approximately triangles.

第二の側面板２４の蓋側の端部には、台形状のサイドフラップ５４が延設され、第二の折罫線５６で第二の側面板２４と区切られている。サイドフラップ５４の延出長さは、第一及び第三の側面板２２，２６の連接方向の長さの1/2よりも少し短い。底側の端部にも台形状のサイドフラップ５８が延設され、折罫線６０で第二の側面板２４と区切られている。 A trapezoidal side flap 54 is extended at the end of the second side plate 24 on the lid side, and is separated from the second side plate 24 by a second fold ruled line 56. The extending length of the side flap 54 is slightly shorter than 1/2 of the length of the first and third side plates 22 and 26 in the connecting direction. A trapezoidal side flap 58 is also extended at the bottom end, and is separated from the second side plate 24 by a fold ruled line 60.

第三の側面板２６の蓋側の端部には、略長方形の第二の内面板６２が延設され、折罫線６４で第三の側面板２６と区切られている。第二の内面板６２の延出長さは、第三の側面板２６の、連接方向と直角な幅方向の長さの約4/5に設定されている。そして、第二の内面板６２の内側に、一部が折罫線６４と重なる略長方形の透孔６６が形成されている。 A substantially rectangular second inner surface plate 62 is extended at the end of the third side plate 26 on the lid side, and is separated from the third side plate 26 by a fold ruled line 64.

Further, a side flap 82 substantially symmetrical to the side flap 58 is extended to the bottom end, and is separated from the fourth side plate 28 by a fold ruled line 84.

第一の内面板３６の蓋側の端部のほぼ中央の位置には、舌片状の緩衝片８６が延設され、第四の折罫線８８で第一の内面板３６と区切られている。第四の折罫線８８は、第一、第二及び第三の折罫線４２，５６，８０及び折罫線６４よりも底側にずれた位置に設けられている。また、緩衝片８６は、第四の折罫線８８が有る基端部の両側が略Ｖ字形に切り欠かれ、基端部が先端部よりも幅狭になっている。 A tongue piece-shaped cushioning piece 86 is extended at a position approximately at the center of the end of the first inner surface plate 36 on the lid side, and is separated from the first inner surface plate 36 by a fourth fold ruled line 88. .. The fourth fold ruled line 88 is provided at a position shifted to the bottom side from the first, second and third fold ruled lines 42, 56, 80 and the fold ruled line 64. Further, in the buffer piece 86, both sides of the base end portion having the fourth folded ruled line 88 are cut out in a substantially V shape, and the base end portion is narrower than the tip end portion.

次に、仕切り形成部２０について説明する。仕切り形成部２０は、互いに平行に順に連接された下横板９０、可動縦板９２、上横板９４、固定縦板９６、補助横板９８及び補助可動縦板１００で構成され、折罫線１０２．１０４．１０６．１０８，１１０で各々区切られている。そして、下横板９０の連接方向の端部が、折罫線１１２を介して第一の内面板３６の底側の端部に連続している。折罫線１１２の位置は、折罫線５０，６０，７４，８４よりも蓋側にずれた位置に設定されている。 Next, the partition forming portion 20 will be described. The partition forming portion 20 is composed of a lower horizontal plate 90, a movable vertical plate 92, an upper horizontal plate 94, a fixed vertical plate 96, an auxiliary horizontal plate 98, and an auxiliary movable vertical plate 100, which are sequentially connected in parallel with each other, and a fold ruled line 102. It is separated by .104.106.108 and 110, respectively. The end portion of the lower horizontal plate 90 in the connecting direction is continuous with the bottom end portion of the first inner surface plate 36 via the fold ruled line 112. The position of the fold ruled line 112 is set to a position shifted toward the lid side from the fold ruled lines 50, 60, 74, 84.

下横板９０、上横板９４及び補助横板９８の連接方向の長さは、第二及び第四の側面板２４，２８の連接方向長さとほぼ同じか僅かに短い。また、可動縦板９２、固定縦板９６及び補助可動縦板１００の連接方向長さは、順に少しずつ短くなっている。 The length of the lower horizontal plate 90, the upper horizontal plate 94, and the auxiliary horizontal plate 98 in the connecting direction is substantially the same as or slightly shorter than the length of the second and fourth side plates 24, 28 in the connecting direction. Further, the lengths of the movable vertical plate 92, the fixed vertical plate 96, and the auxiliary movable vertical plate 100 in the connecting direction are gradually shortened in order.

上横板９４及び補助横板９８の内側には、収容物Ｓの胴部が入る大きさの透孔９４ａ，９８ａが各々設けられている。また、可動縦板９２と下横板９０との境界部は、折罫線１０２の中央部が中断され、この中断された位置から可動縦板９２の内側に向かって膨出する短い舌片状の係合部１１４が切り込み線によって一対に設けられ、さらに一対の係合部１１４に間の挟まれるように、下横板９０の内側に向かって膨出する舌片状の支持脚片１１６が切り込み線によって設けられている。 Inside the upper horizontal plate 94 and the auxiliary horizontal plate 98, through holes 94a and 98a having a size for inserting the body of the container S are provided, respectively. Further, the boundary portion between the movable vertical plate 92 and the lower horizontal plate 90 is in the shape of a short tongue piece in which the central portion of the folded ruled line 102 is interrupted and bulges inward from the interrupted position toward the inside of the movable vertical plate 92. A pair of engaging portions 114 are provided by a notch line, and a tongue piece-shaped support leg piece 116 that bulges toward the inside of the lower horizontal plate 90 is notched so as to be sandwiched between the pair of engaging portions 114. It is provided by a line.

このように、箱体形成片１６は、外箱形成部１８と仕切り形成部２０とで構成され、外箱形成部１８及び仕切り形成部２０は、第一の内面板３６と下横板９０の端部同士が連続して一体になっている。 As described above, the box body forming piece 16 is composed of the outer box forming portion 18 and the partition forming portion 20, and the outer box forming portion 18 and the partition forming portion 20 are the first inner surface plate 36 and the lower horizontal plate 90. The ends are continuously integrated.

次に、緩衝用仕切り付き包装箱１０の組み立て方法の一例を説明する。ここでは、図２に示す箱体形成片１６の各折罫線の折り曲げ方について、表面が凸になる折り方を正折り、裏面が凸になる折り方を逆折りと称する。 Next, an example of an assembling method of the packaging box 10 with a cushioning partition will be described. Here, regarding the folding method of each folding ruled line of the box body forming piece 16 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.

まず、図３（ａ）に示すように、折罫線１０８を正折りして補助横板９８及び補助可動縦板１００を上横板９４及び固定縦板９６の裏面側に重ね、補助可動縦板１００の表面に糊１１８を塗布する。そして、図３（ｂ）に示すように、折罫線１０４を正折りして補助横板９８及び補助可動縦板１００を下横板９０及び可動縦板９２の裏面側に重ね、補助可動縦板１００を可動縦板９２に糊付けする。 First, as shown in FIG. 3A, the folding ruled line 108 is folded forward and the auxiliary horizontal plate 98 and the auxiliary movable vertical plate 100 are overlapped on the back surface side of the upper horizontal plate 94 and the fixed vertical plate 96. Glue 118 is applied to the surface of 100. Then, as shown in FIG. 3B, the folding ruled line 104 is folded forward and the auxiliary horizontal plate 98 and the auxiliary movable vertical plate 100 are overlapped on the back surface side of the lower horizontal plate 90 and the movable vertical plate 92, and the auxiliary movable vertical plate is overlapped. 100 is glued to the movable vertical plate 92.

さらに、固定縦板９６の表面に糊１２０を塗布した後、図４（ａ）に示すように、折罫線１１２を正折りすることによって上横板９４及び固定縦板９６を第一の内面板３６の裏面側に重ね、固定縦板９６を第一の内面板３６に糊付けする。これで、仕切り形成部２０の各部材が第一の内面板３６の裏面側に折り重なった状態になる。そして、第二の内面板６２を折罫線６４で正折りし、第二の内面板６２を第三の側面板２６の裏面側に重ねる。 Further, after applying the glue 120 to the surface of the fixed vertical plate 96, as shown in FIG. 4A, the upper horizontal plate 94 and the fixed vertical plate 96 are formed into the first inner surface plate by folding the folded ruled line 112 forward. The fixed vertical plate 96 is laminated on the back surface side of the 36 and glued to the first inner surface plate 36. As a result, each member of the partition forming portion 20 is folded on the back surface side of the first inner surface plate 36. Then, the second inner surface plate 62 is folded forward along the fold ruled line 64, and the second inner surface plate 62 is overlapped with the back surface side of the third side surface plate 26.

その後、図４（ｂ）に示すように、折罫線３８を正折りすることによって仕切り形成部２０の各部材及び第一の内面板３６を第四の側面板２８の裏面側に重ね、第一の内面板３６の表面に糊１２２を塗布する。そして、図５に示すように、折罫線３２を正折りすることによって第一及び第二の側面板２２，２４を第一及び第二の内面板３６，６２の表面側に重ね、第一の側面板２２を第一の内面板３６に糊付けする。箱体形成片１６は、この折り畳み状態で緩衝用仕切り付き包装箱１０を製造する工場等から出荷される。 After that, as shown in FIG. 4B, each member of the partition forming portion 20 and the first inner surface plate 36 are overlapped on the back surface side of the fourth side plate 28 by folding the fold ruled line 38 forward, and the first The glue 122 is applied to the surface of the inner surface plate 36 of the above. Then, as shown in FIG. 5, by folding the fold ruled line 32 forward, the first and second side surface plates 22, 24 are overlapped on the surface side of the first and second inner surface plates 36, 62, and the first The side plate 22 is glued to the first inner plate 36. The box body forming piece 16 is shipped from a factory or the like that manufactures a packaging box 10 with a cushioning partition in this folded state.

次に収容物Ｓを包装する工場等において、箱体形成片１６を立体的にする。まず、折罫線３０，３２，３４，３８を各々９０度に正折りして、４つの側面板２２，２４，２６，２８と第一及び第二の内面板３６，６２とで成る四角形の筒体１２４を形成する。その後、筒体１２４の底側の端部を閉鎖するため、折罫線６０，８４でサイドフラップ５８，８２を各々９０度に正折りし、第一の底片４８を折罫線５０で９０度に正折りしてサイドフラップ５８，８２に重ねる。そして、第一の底片４８の表面に糊１２６を塗布した後、第二の底片７２を９０度に正折りして第一の底片４８に重ね、第二の底片７２の先端側領域７２ｂを第一の底片４８に糊付けする。これでシールエンド型の底部１２８が形成され、図６（ａ）〜（ｄ）及び図７（ａ）に示す状態になる。 Next, in a factory or the like for packaging the contents S, the box body forming piece 16 is made three-dimensional. First, the fold ruled lines 30, 32, 34, 38 are folded forward at 90 degrees, respectively, and a quadrangular cylinder composed of four side plates 22, 24, 26, 28 and the first and second inner plates 36, 62. Form body 124. After that, in order to close the bottom end of the cylinder 124, the side flaps 58 and 82 are properly folded at 90 degrees at the folded ruled lines 60 and 84, and the first bottom piece 48 is positively folded at 90 degrees at the folded ruled line 50. Fold it and stack it on the side flaps 58 and 82. Then, after applying the glue 126 to the surface of the first bottom piece 48, the second bottom piece 72 is folded forward at 90 degrees and overlapped with the first bottom piece 48, and the tip end side region 72b of the second bottom piece 72 is formed. Glue to one bottom piece 48. As a result, the bottom 128 of the seal end type is formed, and the states shown in FIGS. 6 (a) to 6 (d) and 7 (a) are obtained.

この状態を簡単に説明すると、図６（ｄ）に示すように、底部１２８は、第一及び第二の底片４８，７２が互いに糊付けられ、第一の底片４８の補助折罫線５２が第二の底片７２の解体用破断線７６にほぼ重なる。また、図７（ａ）に示すように、第二の内面板６２が第三の側面板２６の内面側に重なり、第三の側面板２６の開封部７０及び開封用破断線６８が透孔６６の内側に収まり、緩衝片８６の上端部は、筒体１２４の蓋側の端部から突出する。仕切り形成部２０の各部材は、互いに折り重なって第一の内面板３６の内面側に配置され、可動縦板９２や上横板９４の一部が筒体１２４の蓋側の端部から突出する。 To briefly explain this state, as shown in FIG. 6D, in the bottom 128, the first and second bottom pieces 48 and 72 are glued to each other, and the auxiliary crease line 52 of the first bottom piece 48 is second. It almost overlaps with the dismantling break line 76 of the bottom piece 72. Further, as shown in FIG. 7A, the second inner surface plate 62 overlaps with the inner surface side of the third side surface plate 26, and the opening portion 70 and the opening breaking line 68 of the third side surface plate 26 are through holes. It fits inside the 66 and the upper end of the cushioning piece 86 projects from the lid-side end of the cylinder 124. Each member of the partition forming portion 20 is folded against each other and arranged on the inner surface side of the first inner surface plate 36, and a part of the movable vertical plate 92 and the upper horizontal plate 94 protrudes from the end portion of the tubular body 124 on the lid side. ..

次に、仕切り形成部２０を立体的にするため、上横板９４の端部（折罫線１０４の近傍）を底部１２８の方向に押し込む。この時、仕切り形成部２０の各折罫線に、折り畳み状態を維持しようとする弾発力が発生するので、この弾発力に抗して押し込むことになる。 Next, in order to make the partition forming portion 20 three-dimensional, the end portion (near the folded ruled line 104) of the upper horizontal plate 94 is pushed in the direction of the bottom portion 128. At this time, since an elastic force for maintaining the folded state is generated in each folded ruled line of the partition forming portion 20, the elastic force is pushed against the elastic force.

上横板９４の端部（折罫線１０４の近傍）を押し込むと、図７（ｂ）に示すように、固定縦板９６が第一の内面板３６の内面に糊付けされているので、可動縦板９２が移動して第三の側面板２６の近傍に対向し、係合部１１４が可動縦板９２から抜け出て下横板９０と面一になって第三の側面板２６に向かって突出し、仕切り形成部２０の各折罫線がほぼ９０度に屈曲した時、係合部１１４が第二の内面板６２の係合受け部６２ａに係合する。また、支持脚片１１６が下横板９０から抜け出て可動縦板９２と面一になって底部１２８に向かって突出し、支持脚片１１６の先端部が底部１２８（サイドフラップ５８，８２）の内面に係止される。そして、下横板９０が、第一の内面板３６及び可動縦板９２に両端部が支持されて底部１２８の上方に配置され、上横板９４が、固定縦板９６及び可動縦板９２に両端部が支持されて下横板９０の上方に配置される。また、補助可動縦板１００が可動縦板９２の内面に糊付けされているので、補助横板９８が、固定縦板９６及び補助可動縦板１００に両端部が支持されて上横板９４と下横板９０との間に配置される。これで、立体的な緩衝用仕切り１４が形成されるので、上横板９４を押し込む動作を止める。 When the end portion of the upper horizontal plate 94 (near the folded ruled line 104) is pushed in, as shown in FIG. 7B, the fixed vertical plate 96 is glued to the inner surface of the first inner surface plate 36, so that the movable vertical plate 96 is movable. The plate 92 moves and faces the vicinity of the third side plate 26, and the engaging portion 114 escapes from the movable vertical plate 92, becomes flush with the lower horizontal plate 90, and protrudes toward the third side plate 26. When each folded ruled line of the partition forming portion 20 is bent at approximately 90 degrees, the engaging portion 114 engages with the engaging receiving portion 62a of the second inner surface plate 62. Further, the support leg piece 116 escapes from the lower horizontal plate 90 and is flush with the movable vertical plate 92 so as to project toward the bottom 128, and the tip portion of the support leg piece 116 is the inner surface of the bottom 128 (side flaps 58, 82). Locked to. Then, the lower horizontal plate 90 is arranged above the bottom portion 128 with both ends supported by the first inner surface plate 36 and the movable vertical plate 92, and the upper horizontal plate 94 is placed on the fixed vertical plate 96 and the movable vertical plate 92. Both ends are supported and arranged above the lower horizontal plate 90. Further, since the auxiliary movable vertical plate 100 is glued to the inner surface of the movable vertical plate 92, both ends of the auxiliary horizontal plate 98 are supported by the fixed vertical plate 96 and the auxiliary movable vertical plate 100, and the upper horizontal plate 94 and the lower side are supported. It is arranged between the horizontal plate 90 and the horizontal plate 90. As a result, the three-dimensional buffer partition 14 is formed, so that the operation of pushing the upper horizontal plate 94 is stopped.

上横板９４を押し込む動作を止めると、緩衝用仕切り１４は、各折罫線に発生する弾発力で折り畳み状態に戻ろうとするが、係合部１１４が係合受け部６２ａに係合しているので、適切な立体形状に保持される。 When the operation of pushing the upper horizontal plate 94 is stopped, the cushioning partition 14 tries to return to the folded state by the elastic force generated in each folding ruled line, but the engaging portion 114 engages with the engaging receiving portion 62a. Therefore, it is maintained in an appropriate three-dimensional shape.

次に、図８（ａ）に示すように、収容物Ｓを筒体１２４の蓋側の端部から中に入れて、緩衝用仕切り１４に支持させる。収容物Ｓは、下部が下横板９０の上面で支持され、側面の上側の位置が上横板９４の透孔９４ａの内周縁部でガイドされ、側面の中央からやや下側の位置が補助横板９８の透孔９８ａの内周縁部でガイドされる。 Next, as shown in FIG. 8A, the inclusion S is inserted into the cylinder 124 from the end on the lid side and supported by the cushioning partition 14. The lower part of the inclusion S is supported by the upper surface of the lower horizontal plate 90, the upper position of the side surface is guided by the inner peripheral edge portion of the through hole 94a of the upper horizontal plate 94, and the position slightly lower than the center of the side surface is assisted. It is guided by the inner peripheral edge of the through hole 98a of the horizontal plate 98.

収容物Ｓを入れると、筒体１２４の蓋側の端部を閉鎖するため、第二及び第三の折罫線５６，８０でサイドフラップ５４，７８を各々９０度に正折りする。そして、差し込み片４４の表面に糊１３０を塗布した後、折罫線４６を９０度に正折りして差し込み片４４を倒し、蓋片４０を第一の折罫線４２で正折りしてサイドフラップ５４，８０に重ねる。これにより、緩衝片８６は、蓋片４０に押されて第四の折罫線８８で自動的に屈曲する。 When the container S is inserted, the side flaps 54 and 78 are folded forward at 90 degrees at the second and third fold ruled lines 56 and 80 in order to close the end portion of the cylinder 124 on the lid side. Then, after applying the glue 130 to the surface of the insertion piece 44, the folding ruled line 46 is folded forward at 90 degrees to tilt the insertion piece 44, and the lid piece 40 is normally folded along the first folding ruled line 42 to form the side flap 54. , 80. As a result, the cushioning piece 86 is pushed by the lid piece 40 and automatically bent at the fourth fold ruled line 88.

そして、蓋片４０で筒体１２４の端部を塞ぎ、差し込み片４４をサイドフラップ５４，７８と第二の内面板６２及び第三の側面板２６との隙間に差し込み、差し込み片４４を、透孔６６を通じて開封部７０の裏面に糊付けする。これで、蓋片４０、緩衝片８６及びサイドフラップ５４，７８が順に重なった蓋部１３２が形成され、図８（ｂ）及び図１（ａ）、（ｂ）に示す組み立て状態になる。 Then, the end portion of the tubular body 124 is closed with the lid piece 40, the insertion piece 44 is inserted into the gap between the side flaps 54 and 78 and the second inner surface plate 62 and the third side surface plate 26, and the insertion piece 44 is transparent. It is glued to the back surface of the opening portion 70 through the hole 66. As a result, the lid portion 132 in which the lid piece 40, the cushioning piece 86, and the side flaps 54 and 78 are sequentially overlapped is formed, and the assembled state shown in FIGS. 8 (b) and 1 (a) and 1 (b) is obtained.

この組み立て状態で、緩衝片８６は、第四の折罫線８８で斜めに折れ曲がり、先端部が蓋片４０の内面に係止されて筒体１２４の中に収まる。サイドフラップ５４，７８は、第二及び第三の折罫線５６，７８で折れ曲がり、緩衝片８６の内面に押されて斜め下向きに配され、蓋片４０と緩衝片８６との間に緩衝用の空間が形成され、収容物Ｓの上部がサイドフラップ５４，７８及び緩衝片８６によって緩衝的に保護される。 In this assembled state, the cushioning piece 86 is bent diagonally at the fourth folding ruled line 88, and the tip end portion is locked to the inner surface of the lid piece 40 and fits in the tubular body 124. The side flaps 54 and 78 are bent at the second and third fold ruled lines 56 and 78, pushed by the inner surface of the cushioning piece 86 and arranged diagonally downward, and are used for cushioning between the lid piece 40 and the cushioning piece 86. A space is formed and the upper part of the inclusion S is buffered by the side flaps 54, 78 and the buffer piece 86.

緩衝用仕切り付き包装箱１０の蓋部１３２を開封する時は、第三の側面板２６の開封部７０を指で押し込んで開封用破断線６８を破断させ、蓋片４０及び差し込み片４４を摘んで引き上げる。このとき、開封部７０は、第三の側面板２６から分離するが、差し込み片４４に糊付けされて一緒に移動するので、ゴミにならない。そして、図８（ａ）に示すように、緩衝片８６及びサイドフラップ５４，７８を引き上げて筒体１２４の端部を開放すると、中の収容物Ｓを取り出すことができる。 When opening the lid 132 of the packaging box 10 with a cushioning partition, the opening 70 of the third side plate 26 is pushed in with a finger to break the opening breaking line 68, and the lid piece 40 and the insertion piece 44 are picked up. Then pull it up. At this time, the opening portion 70 is separated from the third side plate 26, but is glued to the insertion piece 44 and moves together, so that it does not become dust. Then, as shown in FIG. 8A, when the cushioning piece 86 and the side flaps 54 and 78 are pulled up to open the end portion of the tubular body 124, the contained object S inside can be taken out.

開封した後で再封する時は、サイドフラップ５４，７８、緩衝片８６及び蓋片４０を順に倒し、差し込み片４４を第二の内面板６２の内面側に差し込めばよい。 When resealing after opening, the side flaps 54, 78, the cushioning piece 86, and the lid piece 40 may be tilted in order, and the insertion piece 44 may be inserted into the inner surface side of the second inner surface plate 62.

使用後、緩衝用仕切り付き包装箱１０を廃棄する時は、立体的な緩衝用仕切り付き包装箱１０を折り畳み可能な状態にする。まず、第二の底片７２の中央部を指で押し込んで解体用破断線７６を破断させ、先端側領域７２ｂを第二の底片７２（基端側領域７２ａ）から分離させ、底部１２８を解体する。このとき、分離した先端側領域７２ｂは第一の底片４８に糊付けされて一緒に移動するので、ゴミにならない。また、第一の底片４８の内側に、解体用破断線７６に重なる補助折罫線５２が設けてあるので、第一の底片４８の両角部が適切に折れ曲がり、解体用破断線７６をスムーズに破断させることができる。 When the packaging box 10 with a cushioning partition is discarded after use, the three-dimensional packaging box 10 with a cushioning partition is made foldable. First, the central portion of the second bottom piece 72 is pushed with a finger to break the dismantling break line 76, the tip end side region 72b is separated from the second bottom piece 72 (base end side region 72a), and the bottom portion 128 is dismantled. .. At this time, the separated tip side region 72b is glued to the first bottom piece 48 and moves together, so that it does not become dust. Further, since the auxiliary crease line 52 overlapping the dismantling break line 76 is provided inside the first bottom piece 48, both corners of the first bottom piece 48 are appropriately bent and the dismantling break line 76 is smoothly broken. Can be made to.

底部１２８を解体すると、さらに第一の底片４８及び先端側領域７２ｂを深く押し込み、第一の底片４８の内面（又は図示しないサイドフラップ５８，８２の内面）で下横板９０の下面を押し上げる。すると、図９（ｂ）に示すように、係合部１１４と係合受け部６２ａとの係合が解除され、立体的な緩衝用仕切り部１４を元の折り畳み状態に戻すことができる。底部１２８の解体と緩衝用仕切り１４を折り畳みは、ほぼ１アクションで簡単に行うことができる。そして、筒体１２４を平坦な折り畳み状態にすることによって、緩衝機能付き包装箱１０をコンパクトに廃棄することができる。 When the bottom portion 128 is disassembled, the first bottom piece 48 and the tip side region 72b are further pushed deeply, and the lower surface of the lower horizontal plate 90 is pushed up by the inner surface of the first bottom piece 48 (or the inner surface of the side flaps 58 and 82 (not shown)). Then, as shown in FIG. 9B, the engagement between the engaging portion 114 and the engaging receiving portion 62a is released, and the three-dimensional cushioning partition portion 14 can be returned to the original folded state. Dismantling the bottom 128 and folding the cushioning partition 14 can be easily done in almost one action. Then, by putting the cylinder 124 in a flat folded state, the packaging box 10 with a cushioning function can be compactly disposed of.

以上説明したように、緩衝仕切り付き包装箱１０は、一枚の箱体形成片１８で成るシンプルな構造であり、収容物Ｓが緩衝用仕切り１４にセットされると、収容物Ｓの下部が下横板９０の上面に支持され、収容物Ｓの側面が上横板９４及び補助横板９８の透孔９４ａ，９８ａの内周縁部でガイドされ、収容物Ｓの上部がサイドフラップ５４，７８及び緩衝片８６によって保護され、収容物Ｓが外箱１２に接触しないように安全に保持される。 As described above, the packaging box 10 with a buffer partition has a simple structure composed of one box body forming piece 18, and when the container S is set in the buffer partition 14, the lower portion of the container S becomes. Supported by the upper surface of the lower horizontal plate 90, the side surface of the inclusion S is guided by the inner peripheral edges of the through holes 94a, 98a of the upper horizontal plate 94 and the auxiliary horizontal plate 98, and the upper portion of the inclusion S is the side flaps 54, 78. And protected by the buffer piece 86, the contents S are safely held so as not to come into contact with the outer box 12.

また、外箱１２の内側の係合受け部６２ａに緩衝用仕切り１４の係合部１１４が係合することによって、緩衝用仕切り１４が折り畳み状態に戻ろうとする動作が阻止され、緩衝用仕切り１４を適切な立体形状に保持させることができる。しかも、組み立て時、折り畳み状態の緩衝用仕切り１４を立体的にすることで、係合部１１４を係合受け部６２ａに自動的且つスムーズに係合させることができ、非常に組み立てやすい。また、蓋部１３２の緩衝構造についても、糊付け等の特別な作業は不要であり、蓋側の端部を蓋部１３２で閉鎖する作業を行う中で自動的に形成されるので、非常に組み立てやすい。その他、使用後、緩衝用仕切り付き包装箱１０を折り畳んで廃棄するための作業も簡単である。 Further, by engaging the engaging portion 114 of the cushioning partition 14 with the engaging receiving portion 62a inside the outer box 12, the operation of the cushioning partition 14 to return to the folded state is prevented, and the cushioning partition 14 is prevented from returning to the folded state. Can be held in an appropriate three-dimensional shape. Moreover, by making the cushioning partition 14 in the folded state three-dimensional at the time of assembly, the engaging portion 114 can be automatically and smoothly engaged with the engaging receiving portion 62a, which is very easy to assemble. Further, the cushioning structure of the lid portion 132 does not require any special work such as gluing, and is automatically formed during the work of closing the end portion on the lid side with the lid portion 132, so that it is very assembled. Cheap. In addition, after use, the work of folding and disposing of the packaging box 10 with a cushioning partition is also easy.

次に、本考案の緩衝用仕切り付き包装箱の第二の実施形態について、図１０、図１１に基づいて説明する。ここで、上記の緩衝用仕切り付き包装箱１０（及び箱体形成片１６）と同様の構成は、同一の符号を付して説明を省略する。 Next, a second embodiment of the packaging box with a buffer partition of the present invention will be described with reference to FIGS. 10 and 11. Here, the same configuration as the above-mentioned packaging box 10 with a partition for cushioning (and the box body forming piece 16) is designated by the same reference numerals, and the description thereof will be omitted.

この実施形態の緩衝用仕切り付き包装箱１３４は、図１０（ａ）に示すように、略直方体の外箱１２と、外箱１２の中に配置された緩衝用仕切り１４とで構成され、図１０（ｂ）に示すように、収容物Ｓを２個ずつ包装する包装箱として使用される。つまり、１個入りの緩衝用仕切り付き包装箱１０を２個入りの包装箱に改変したものである。 As shown in FIG. 10A, the packaging box 134 with a cushioning partition of this embodiment is composed of a substantially rectangular parallelepiped outer box 12 and a cushioning partition 14 arranged in the outer box 12. As shown in 10 (b), it is used as a packaging box for packaging two containers S each. That is, the packaging box 10 with a buffer partition containing one piece is modified into a packaging box containing two pieces.

緩衝用仕切り付き包装箱１３４は、厚紙等で成る一枚の箱体形成片１３６を組み立てることによって形成され、箱体形成片１３６は、図１１に示すように、外箱１２に組み立てられる外箱形成部１３８と、緩衝用仕切り１４に組み立てられる仕切り形成部１４０とで構成される。 The packaging box 134 with a partition for cushioning is formed by assembling a single box body forming piece 136 made of cardboard or the like, and the box body forming piece 136 is an outer box assembled to the outer box 12 as shown in FIG. It is composed of a forming portion 138 and a partition forming portion 140 assembled on the cushioning partition 14.

箱体形成片１３６の構成は、上記の箱体形成片１６とほぼ同じであるが、２個入りにするため、複数の板のサイズが大きくなっている点と、上横板９４及び補助横板９８の透孔９４ａ，９８ａが２個ずつ形成されている点が異なる。 The structure of the box body forming piece 136 is almost the same as that of the box body forming piece 16 described above, but the size of the plurality of plates is increased in order to include two pieces, and the upper horizontal plate 94 and the auxiliary horizontal plate are used. The difference is that two through holes 94a and 98a of the plate 98 are formed.

緩衝用仕切り付き包装箱１３４の組み立て方法、蓋部１３２を開封し再封する動作、及び廃棄時の動作は、上記の緩衝用仕切り付き包装箱１０と同様である。この緩衝用仕切り付き包装箱１３４においても、上記の緩衝用仕切り付き包装箱１０とほぼ同様の作用効果が得られる。 The method of assembling the packaging box 134 with a cushioning partition, the operation of opening and resealing the lid 132, and the operation at the time of disposal are the same as the above-mentioned packaging box 10 with a cushioning partition. Also in this packaging box 134 with a cushioning partition, substantially the same effect as that of the above-mentioned packaging box 10 with a cushioning partition can be obtained.

次に、本考案の緩衝用仕切り付き包装箱の第三の実施形態について、図１２〜図１４に基づいて説明する。ここで、上記の緩衝用仕切り付き包装箱１０（及び箱体形成片１６）と同様の構成は、同一の符号を付して説明を省略する。 Next, a third embodiment of the packaging box with a buffer partition of the present invention will be described with reference to FIGS. 12 to 14. Here, the same configuration as the above-mentioned packaging box 10 with a partition for cushioning (and the box body forming piece 16) is designated by the same reference numerals, and the description thereof will be omitted.

この実施形態の緩衝用仕切り付き包装箱１４２は、図１２（ａ）に示すように、略直方体の外箱１２と、外箱１２の中に配置された緩衝用仕切り１４とで構成され、図１２（ｂ）に示すように、収容物Ｓを５個ずつ包装する包装箱として使用される。つまり、１個入りの緩衝用仕切り付き包装箱１０を５個入りの包装箱に改変したものである。 As shown in FIG. 12A, the packaging box 142 with a cushioning partition of this embodiment is composed of a substantially rectangular parallelepiped outer box 12 and a cushioning partition 14 arranged in the outer box 12. As shown in 12 (b), it is used as a packaging box for packaging five containers S at a time. That is, the packaging box 10 with a buffer partition containing one piece is modified into a packaging box containing five pieces.

緩衝用仕切り付き包装箱１４２は、厚紙等で成る一枚の箱体形成片１４４を組み立てることによって形成され、箱体形成片１４４は、図１３に示すように、外箱１２に組み立てられる外箱形成部１４６と、緩衝用仕切り１４に組み立てられる仕切り形成部１４８とで構成される。 The packaging box 142 with a partition for cushioning is formed by assembling a single box body forming piece 144 made of cardboard or the like, and the box body forming piece 144 is an outer box assembled to the outer box 12 as shown in FIG. It is composed of a forming portion 146 and a partition forming portion 148 assembled on the cushioning partition 14.

箱体形成片１４４の構成は、上記の箱体形成片１６と共通点が多いが、５個入りにするため、複数の板のサイズが大きくなっている点と、上横板９４及び補助横板９８の透孔９４ａ，９８ａが５個ずつ形成されている点が異なる。さらに、第二の内面板６２の内側に、略菱形の透孔で成る係合受け部６２ｂが設けられている点と、係合受け部６２ｂに係合する係合部１５０が、可動縦板９２と下横板９０との境界部ではなく、可動縦板９２と上横板９４との境界部に設けられている点が異なる。 The structure of the box body forming piece 144 has much in common with the above-mentioned box body forming piece 16, but the size of a plurality of plates is increased in order to contain 5 pieces, and the upper horizontal plate 94 and the auxiliary horizontal plate are used. The difference is that five through holes 94a and 98a of the plate 98 are formed. Further, a point where an engaging receiving portion 62b made of a substantially rhombic through hole is provided inside the second inner surface plate 62, and an engaging portion 150 engaging with the engaging receiving portion 62b are movable vertical plates. The difference is that they are provided not at the boundary between the 92 and the lower horizontal plate 90 but at the boundary between the movable vertical plate 92 and the upper horizontal plate 94.

緩衝用仕切り付き包装箱１３４の組み立て方法は、上記の緩衝用仕切り付き包装箱１０と基本的に同じである。ただし、係合部１５０及び係合受け部６２ｂの構成が変更されているので、これらが係合する時の動作が少し違ってくる。 The method of assembling the packaging box 134 with a cushioning partition is basically the same as the above-mentioned packaging box 10 with a cushioning partition. However, since the configurations of the engaging portion 150 and the engaging receiving portion 62b have been changed, the operation when they are engaged is slightly different.

図１４（ａ）は、緩衝用仕切り付き包装箱１３４（箱体形成片１４４）を組み立てる途中の、筒体１２４を立体的にして底部１２８を形成した状態を示している。この状態で、筒体１２４の中の仕切り形成部１４８の各部材は、互いに折り重なって第一の内面板３６の内面側に配置され、可動縦板９２や上横板９４の一部が筒体１２４の蓋側の端部から突出する。これは、図７（ａ）に示す緩衝用仕切り付き包装箱１０（箱体形成片１６）の状態とほぼ同じである。 FIG. 14A shows a state in which the tubular body 124 is three-dimensionally formed to form the bottom 128 while the packaging box 134 with the cushioning partition (box body forming piece 144) is being assembled. In this state, each member of the partition forming portion 148 in the cylinder 124 is folded against each other and arranged on the inner surface side of the first inner surface plate 36, and a part of the movable vertical plate 92 and the upper horizontal plate 94 is a cylinder. It protrudes from the end of 124 on the lid side. This is almost the same as the state of the packaging box 10 with a cushioning partition (box body forming piece 16) shown in FIG. 7 (a).

この状態から、仕切り形成部１４８を立体的にするため、上横板９４の端部（折罫線１０４の近傍）を底部１２８の方向に押し込むと、図１４（ｂ）に示すように、可動縦板９２が移動して第三の側面板２６の近傍に対向し、可動縦板９２から抜け出た係合部１５０が上横板９４と面一になって第三の側面板２６に向かって突出し、仕切り形成部１４８の各折罫線がほぼ９０度に屈曲した時、係合部１５０が第二の内面板６２の係合受け部６２ｂの中に入って係合する。これで、立体的な緩衝用仕切り１４が形成されるので、上横板９４の押し込みを止める。 From this state, in order to make the partition forming portion 148 three-dimensional, when the end portion (near the folded ruled line 104) of the upper horizontal plate 94 is pushed in the direction of the bottom portion 128, as shown in FIG. The plate 92 moves and faces the vicinity of the third side plate 26, and the engaging portion 150 that has come out of the movable vertical plate 92 is flush with the upper horizontal plate 94 and protrudes toward the third side plate 26. When each folded ruled line of the partition forming portion 148 is bent at approximately 90 degrees, the engaging portion 150 enters and engages with the engaging receiving portion 62b of the second inner surface plate 62. As a result, the three-dimensional cushioning partition 14 is formed, so that the pushing of the upper horizontal plate 94 is stopped.

上横板９４の端部を押し込む動作を止めると、緩衝用仕切り１４は、各折罫線の弾発力によって折り畳み状態に戻ろうとするが、係合部１５０が係合受け部６２ｂの中に入って係合しているので、適切な立体形状に保持される。 When the operation of pushing the end portion of the upper horizontal plate 94 is stopped, the cushioning partition 14 tries to return to the folded state by the elastic force of each folding ruled line, but the engaging portion 150 enters the engaging receiving portion 62b. Since they are engaged with each other, they are held in an appropriate three-dimensional shape.

また、５個の収容物Ｓを包装した組み立て状態で、緩衝片８６は、第四の折罫線８８で斜めに折れ曲がり、先端部が蓋片４０の内面に係止されて筒体１２４の中に収まる。サイドフラップ５４，７８は、第二及び第三の折罫線５６，７８で折れ曲がり、緩衝片８６の内面に押されて斜め下向きに配され、蓋片４０と緩衝片８６との間に緩衝用の空間が形成される。そして、５個の収容物Ｓの中の両端にある２個は、上部がサイドフラップ５４，７８及び緩衝片８６によって緩衝的に保護され、その他の３個は、上部が緩衝片８６によって緩衝的に保護される。 Further, in the assembled state in which the five containers S are packaged, the cushioning piece 86 is bent diagonally at the fourth folding ruled line 88, and the tip portion is locked to the inner surface of the lid piece 40 and is contained in the cylinder 124. It fits. The side flaps 54 and 78 are bent at the second and third fold ruled lines 56 and 78, pushed by the inner surface of the cushioning piece 86 and arranged diagonally downward, and are used for cushioning between the lid piece 40 and the cushioning piece 86. Space is formed. Two of the five inclusions S at both ends are buffered at the top by the side flaps 54, 78 and the buffer piece 86, and the other three are buffered at the top by the buffer piece 86. Protected by.

緩衝用仕切り付き包装箱１４２の蓋部１３２の開封と再封の方法、及び廃棄時の作業は、上記の緩衝用仕切り付き包装箱１０と同様である。この緩衝用仕切り付き包装箱１４２においても、上記の緩衝用仕切り付き包装箱１０と同様の作用効果が得られる。 The method of opening and resealing the lid 132 of the packaging box 142 with a cushioning partition and the work at the time of disposal are the same as those of the packaging box 10 with a cushioning partition. Also in this packaging box 142 with a cushioning partition, the same function and effect as the above-mentioned packaging box 10 with a cushioning partition can be obtained.

なお、本考案の緩衝用仕切り付き包装箱は、上記実施形態に限定されるものではない。例えば、仕切り形成部に設ける係合部と第二の内面板に設ける係合受け部は、緩衝用仕切り部を立体的に形成する（筒体の蓋側の端部から突出している上横板の端部を底部の方向に押し込む）ことによって互いに係合するものであればよく、個々の形状や大きさ、組数や配置は適宜変更することができる。 The packaging box with a buffer partition of the present invention is not limited to the above embodiment. For example, the engaging portion provided in the partition forming portion and the engaging receiving portion provided in the second inner surface plate form the cushioning partition portion three-dimensionally (the upper horizontal plate protruding from the end portion on the lid side of the cylinder). It suffices as long as it engages with each other by pushing the end portion toward the bottom), and the individual shapes, sizes, number of sets and arrangement can be appropriately changed.

緩衝用仕切りの補助横板及び補助可動板は、収容物が緩衝用仕切りの中で傾くのを防止するために設けたものであり、必要なければ省略することができる。また、支持脚片は、緩衝用仕切りに収容物をセットした時、下横板が収容物の質量を受けて下向きに傾いてしまうのを防止するために設けたものであり、緩衝用仕切りが折り畳み状態に戻ろうとする弾発力で収容物を支持できる場合、支持脚片は省略することができる。 The auxiliary horizontal plate and the auxiliary movable plate of the cushioning partition are provided to prevent the contained object from tilting in the cushioning partition, and may be omitted if necessary. Further, the support leg piece is provided to prevent the lower horizontal plate from tilting downward due to the mass of the contained object when the contained object is set in the cushioning partition, and the cushioning partition is provided. If the contents can be supported by the elastic force to return to the folded state, the support leg pieces can be omitted.

その他、第三の側面板の開封部（及び開封用破断線）は、必要なければ省略することができる。その場合、第二の内面板が開封部に重ならないようにする必要がないので、上記の透孔６６のような構成は省略することができる。また、外箱及び緩衝用仕切りの大きさや箱体形成片の素材等は、用途に合わせて自由に設定することができる。 In addition, the opening portion (and the opening breaking line) of the third side plate can be omitted if not necessary. In that case, since it is not necessary to prevent the second inner surface plate from overlapping the opened portion, the configuration such as the through hole 66 described above can be omitted. Further, the size of the outer box and the partition for cushioning, the material of the box body forming piece, and the like can be freely set according to the application.
