更に、上内箱Ｂは、図３に示すように、一側の三角折曲板片４１ａに、切れ目を入れて先端に向け漸次幅広となる略台形状の小さな留め片６５を曲げ起こし自在に形成している。一方、他側の三角折曲板片４１ｂと隣接する短辺側の側面板部２１には、留め片６５を嵌め込み可能に、その外形状に合わせた穴形状の受け穴６６を形成してなる。しかも、上内箱Ｂは、図４に示すように、矩形箱状に折り起こして組み立てると、コーナー部分４１の高さが側面板部２０・２１より一段低くなるように三角折曲板片４１ａ・４１ｂを一部切除して一段小さな三角状に形成している。 Further, as shown in FIG. 3, the upper inner box B is capable of bending and raising a substantially trapezoidal small retaining piece 65 which is gradually widened toward the tip by making a cut in the triangular folding plate piece 41a on one side. Forming. On the other hand, the side plate 21 on the short side adjacent to the other side triangular bent plate piece 41b is formed with a hole-shaped receiving hole 66 adapted to its outer shape so that the fastening piece 65 can be fitted. . Moreover, as shown in FIG. 4, when the upper inner box B is folded and assembled into a rectangular box shape, the triangular bent plate piece 41a is set such that the height of the corner portion 41 is one step lower than the side plate portions 20 and 21. -A part of 41b is excised and formed into a smaller triangular shape.

そこで、上内箱Ｂは、組立時に矩形箱状に折り上げてから、図５に示すように、連結手段として、受け穴６６に留め片６５を嵌め込むと、隣り合う三角折曲板片４１ａ・４１ｂが相互に離れて開かないように結合し、矩形箱形の形態が維持される構成になっている。これにより、上内箱Ｂには、各コーナー部分４１に、切込み４０の折り山を支点として三角折曲板片４１ａ・４１ｂが圧接した状態で折り重なる補強リブ５６が、予め形成される。 Therefore, the upper inner box B is folded into a rectangular box shape at the time of assembly, and as shown in FIG. 5, when a fastening piece 65 is fitted into the receiving hole 66 as a connecting means, adjacent triangular bent plate pieces 41a. -41b is connected so as not to open apart from each other, so that a rectangular box shape is maintained. Thereby, in the upper inner box B, the reinforcing ribs 56 are formed in advance in each corner portion 41 so as to be folded in a state in which the triangular bent plate pieces 41a and 41b are in pressure contact with the folding mountain of the cut 40 as a fulcrum.

図示例の下内箱Ｃは、上内箱Ｂと同様、１枚の矩形な紙又はプラスチック製の段ボールを用い、図６に示すように、四方外縁に沿って井桁状に折れ目２２を設け、その折れ目２２に囲まれた内側に、外箱Ａの矩形な前記開口Ｓに合わせた大きさの矩形な物品載置面部ｂを形成する。物品載置面部ｂには、中央に小さな（後述の窓孔３０の１／３程度）矩形の透孔４５を開けておき、窓孔３０の孔縁を形成するために矩形に入れた折れ目７０の四隅から、物品載置面部ｂの対角線に沿って斜めにそれぞれ透孔４５の隅部に向かう切れ目７１を入れて、４つに分離した台形状の内壁片７２を形成してなる。各内壁片７２には、折れ目７０の各辺と平行な折り癖７３を付けている。内壁片７２には、折れ目７０側へ漸次幅広となる台形な係止穴７４が開けられている。そして、下内箱Ｃは、図７に示すように、各内壁片７２を折り癖７３に従い側面板部２７・２８と対向する向きに巻いて、予め略樋形の状態に曲げ癖の付いた補強壁Ｗが側面板部２７・２８に沿って形成されるようになっている。一方、下内箱Ｃは、図６に示すように、折れ目２２の外側において、内壁片７２の各係止穴７４と対応する位置に、切れ目７５を入れて先端側へ漸次幅広となる台形な係止片７６が曲げ起こし自在に設けられている。 The lower inner box C in the illustrated example, like the upper inner box B, uses a piece of rectangular paper or plastic cardboard, and as shown in FIG. A rectangular article placement surface portion b having a size corresponding to the rectangular opening S of the outer box A is formed inside the fold line 22. In the article mounting surface portion b, a small (about 1/3 of a window hole 30 to be described later) rectangular through hole 45 is opened in the center, and a crease formed in a rectangle to form a hole edge of the window hole 30 is formed. The cut-out 71 which goes diagonally to the corner of the through hole 45 from the four corners 70 of the article placement surface portion b obliquely is formed to form the trapezoidal inner wall piece 72 separated into four. Each inner wall piece 72 has a crease 73 parallel to each side of the fold 70. The inner wall piece 72 is formed with a trapezoidal locking hole 74 that gradually becomes wider toward the fold 70. Then, as shown in FIG. 7, the lower inner box C has each inner wall piece 72 wound in a direction facing the side plate portions 27 and 28 according to the folding ridge 73, and has a bent ridge in a substantially bowl-shaped state in advance. A reinforcing wall W is formed along the side plate portions 27 and 28. On the other hand, as shown in FIG. 6, the lower inner box C has a trapezoidal shape that gradually increases in width toward the front end side by inserting a cut 75 at a position corresponding to each locking hole 74 of the inner wall piece 72 outside the fold 22. A locking piece 76 is provided so as to be bent and raised.

更に、下内箱Ｃは、四方の角縁５０ａから井桁状折れ目２２の交点５０ｂとの間に、それぞれ物品載置面部ｂの対角線に沿うように斜めに切込み５０を設けている。組立時、図７に示すように、折れ目２２に沿って曲げ起こすと、四方に側面板部２７・２８が立設されると共に、隣り合う側面板部２７・２８間を切込み５０に沿って内向きに折り込み、即ち折り山が物品載置面部ｂの対角線に沿う内向きに谷折りすると、四隅に、切込み５０の折り山を支点として三角状の折曲板片５１ａ・５１ｂが折り重なるコーナー部分５１が形成され、全体に片側開放の矩形箱状に折り上がる構成になっている。物品載置面部ａは、四方の折れ目２２に沿って矩形枠状をなす窓枠部２９と、窓枠部２９を残して内側を切り取ってあけた窓孔３０と、窓孔３０を覆うように窓枠部２９上に接着して張設した合成樹脂フィルム３５とで形成する。なお、上記図示例において、合成樹脂フィルム２５・３５は、いずれも透明なウレタンフィルム材を用いるが、透明でなくてもよく、またＰＰフィルムの他、各種の合成樹脂製のフィルム材を使用することもできる。 Furthermore, the lower inner box C is provided with diagonal cuts 50 between the corners 50a of the four sides and the intersections 50b of the cross-gap folds 22 along the diagonal lines of the article placement surface portion b. At the time of assembly, as shown in FIG. 7, when bent along the fold line 22, the side plate portions 27 and 28 are erected in four directions, and between the adjacent side plate portions 27 and 28 along the notch 50. When inwardly folded, that is, when the fold is valley-folded inward along the diagonal line of the article placement surface portion b, the corner portions where the triangular bent plate pieces 51a and 51b are folded at the four corners with the fold mountain of the cut 50 as a fulcrum. 51 is formed, and is configured to be folded up into a rectangular box that is open on one side as a whole. The article placement surface portion a covers a window frame portion 29 having a rectangular frame shape along the folds 22 on the four sides, a window hole 30 cut out from the inside leaving the window frame portion 29, and the window hole 30. And a synthetic resin film 35 stretched by bonding on the window frame portion 29. In the illustrated example, each of the synthetic resin films 25 and 35 uses a transparent urethane film material, but may not be transparent, and other than a PP film, various synthetic resin film materials are used. You can also.

更に、下内箱Ｃは、図６に示すように、三角折曲板片５１ａ・５１ｂの上縁に、それぞれ切れ目を入れて先端に向け漸次幅広となる一対の掛止片６１・６２を折り曲げ自在に形成している。そこで、下内箱Ｃは、組立時に矩形箱状に折り上げてから、図８に示すように、連結手段として、掛止片６１・６２を重ねて同一方向に折り倒し、そのうち下側の掛止片６２を折り倒した跡に形成される切欠き穴６３に、上側の掛止片６１を掛け止めると、隣り合う三角折曲板片５１ａ・５１ｂが相互に離れて開かないように結合し、矩形箱形の形態が維持される構成になっている。これにより、下内箱Ｃには、各コーナー部分５１に、切込み５０の折り山を支点として三角折曲板片５１ａ・５１ｂが圧接した状態で折り重なる補強リブ５５が、予め形成される。また、本発明において、下内箱Ｃは、各内壁片７２を折り癖７３に従って側面板部２７・２８と対向する向きに巻き上げるように折り込んで、側面板部２７・２８に筒状の補強壁Ｗが形成される。そして、各内壁片７２の係止穴７４に係止片７６を嵌め込んで止めると、係止片７６で補強壁Ｗの筒状形態がそのまま保持される構成になっている（図２参照）。 Further, as shown in FIG. 6, the lower inner box C bends a pair of hooking pieces 61 and 62 which are gradually widened toward the tip by making cuts at the upper edges of the triangular bent plate pieces 51a and 51b, respectively. It is freely formed. Therefore, the lower inner box C is folded into a rectangular box at the time of assembly, and as shown in FIG. 8, as the connecting means, the latching pieces 61 and 62 are overlapped and folded in the same direction. When the upper latch piece 61 is latched in the notch hole 63 formed in the trace of the folded stop piece 62, the adjacent triangular bent plate pieces 51a and 51b are coupled so as not to open apart from each other. The rectangular box shape is maintained. Thereby, in the lower inner box C, reinforcing ribs 55 are formed in advance in each corner portion 51 so as to be folded in a state where the triangular bent plate pieces 51a and 51b are pressed against each other with the folding mountain of the cut 50 as a fulcrum. Further, in the present invention, the lower inner box C is folded so that each inner wall piece 72 is wound up in a direction facing the side plate portions 27 and 28 according to the folding ridge 73, and the cylindrical reinforcing walls are formed on the side plate portions 27 and 28. W is formed. When the locking piece 76 is fitted and stopped in the locking hole 74 of each inner wall piece 72, the cylindrical shape of the reinforcing wall W is held as it is by the locking piece 76 (see FIG. 2). .

さて、以上のように組み立てた外箱Ａ、上内箱Ｂおよび下内箱Ｃからなる図示物品配送用箱を用い、配送用物品Ｐを輸送するために梱包する場合は、外箱Ａの外蓋片１５ｂを開いてから、手掛け凹部１９ｂに手を掛けて内蓋片１５ａを開いて開口Ｓを開放した状態にしてから、まず、外箱Ａ内に、図９に示すように、物品載置面部ｂを上向きにして下内箱Ｃを嵌め込む。このとき、下内箱Ｃは、切欠き穴６３に上側の掛止片６１を掛け止めて、予め各コーナー部分５１にて三角折曲板片５１ａ・５１ｂ（補強リブ５６）を開かないように結合して矩形箱形の形態が維持されているため、一部を引っ掛けたりすることなく、スムーズに外箱Ａの開口を通して外箱Ａ内の下方へ簡単に嵌め入れることができる。 When using the illustrated article delivery box composed of the outer box A, the upper inner box B, and the lower inner box C assembled as described above and packing the delivery article P for transportation, After the lid piece 15b is opened, a hand is placed on the handle recess 19b so that the inner lid piece 15a is opened and the opening S is opened, and then the article is placed in the outer box A as shown in FIG. The lower inner box C is fitted with the placement surface part b facing upward. At this time, the lower inner box C does not open the triangular bent plate pieces 51 a and 51 b (reinforcing ribs 56) at the respective corner portions 51 in advance by hooking the upper holding pieces 61 into the cutout holes 63. Since they are combined and the rectangular box shape is maintained, they can be easily fitted into the lower side of the outer box A smoothly through the opening of the outer box A without hooking a part thereof.

次いで、下内箱Ｃの物品載置面部ｂの合成樹脂フィルム３５の上に、図１０に示すように、配送用物品Ｐを載せてから、物品押え面部ａを下向きにして合成樹脂フィルム２５で物品Ｐを覆うように上内箱Ｂを外箱Ａ内に嵌め込む。このとき、上内箱Ｂは、受け穴６６に留め片６５を嵌め込んで、予め各コーナー部分４１にて三角折曲板片４１ａ・４１ｂ（補強リブ５５）が開かないように結合して矩形箱形の形態が維持されているため、一部を引っ掛けたりすることなく、スムーズに外箱Ａの開口を通して外箱Ａ内に簡単に嵌め入れることができる。 Next, as shown in FIG. 10, the delivery article P is placed on the synthetic resin film 35 of the article placement surface portion b of the lower inner box C, and then the article holding surface portion a is faced downward with the synthetic resin film 25. The upper inner box B is fitted into the outer box A so as to cover the article P. At this time, the upper inner box B has a rectangular shape in which the fastening pieces 65 are fitted into the receiving holes 66 so that the triangular bent plate pieces 41a and 41b (reinforcing ribs 55) are not opened in advance at each corner portion 41. Since the box shape is maintained, it can be easily fitted into the outer box A through the opening of the outer box A smoothly without hooking a part thereof.

それから、外箱Ａの内蓋片１５ａを第１折曲部１７の折れ目ｘ・ｙ・ｚに沿って内方へ折り込みながら、棚板部１９を交互に倒してストッパ片２０ａ上に載せ、先端片１９ａ側を重ね合わせて外箱Ａの開口Ｓを閉じる。すると、内蓋片１５ａは、図２に示すように、第１折曲部１７において突当て片１７ｃがそれぞれ外箱Ａの対向側板部１０に突き当り、対向側板部間で棚板部１９が水平に突っ張った棚状の姿勢を維持する。このとき、図示物品配送用箱では、内蓋片１５ａを折り込んで閉じたときに棚板部１９をストッパ片２０ａが受け止めて支え、更に内蓋片１５ａ上に外蓋片１５ｂを折り重ねると、内蓋片１５ａと外蓋片１５ｂ間に付属品収納部Ｒが形成される。なお、内蓋片１５ａを内方へ折り込んで閉じるとき、その折り込み動作に従って、左右の棚板部１９の逃げ凹部１９ｃに上内蓋Ｂの対向側面板２０の上縁が係合し、それら対向側板面２０が邪魔にならないようになる。 Then, while folding the inner lid piece 15a of the outer box A along the folds x, y, and z of the first bent portion 17, the shelf portions 19 are alternately tilted and placed on the stopper pieces 20a, The opening S of the outer box A is closed by overlapping the tip pieces 19a side. Then, as shown in FIG. 2, the inner lid piece 15 a has the abutting piece 17 c in contact with the opposing side plate portion 10 of the outer box A in the first bent portion 17, and the shelf plate portion 19 is horizontally between the opposing side plate portions. Maintain a shelf-like posture. At this time, in the illustrated article delivery box, when the inner lid piece 15a is folded and closed, the stopper plate 20a receives and supports the shelf plate portion 19, and further the outer lid piece 15b is folded on the inner lid piece 15a. An accessory storage portion R is formed between the inner lid piece 15a and the outer lid piece 15b. When the inner lid piece 15a is folded inwardly and closed, according to the folding operation, the upper edges of the opposed side plates 20 of the upper inner lid B engage with the relief recesses 19c of the left and right shelf plate portions 19 and face each other. The side plate surface 20 does not get in the way.

しかる後、図示物品配送用箱では、図１１に示すように、マウスや電源アダプタなどの付属品Ｑがあるときは、付属品Ｑを、内蓋片１５ａの棚板部１９上に載せて付属品収納部Ｒに収納する。そして、図２に示すように外箱Ａの外蓋片１５ｂを折り重ねて付属品収納部Ｒを閉じ、最後に、不図示の粘着テープ等で外箱Ａを密封する。これにより、配送用物品Ｐを、外箱Ａ内の中空部位において、上下内箱Ｂ・Ｃの合成樹脂フィルム２５・３５間で挟圧した状態でズレ動くことなく拘束して保持し、たとえ外箱Ａに振動や衝撃が加わっても、その外力を上下の内箱Ｂ・Ｃで緩衝して保護できるように梱包する。 Thereafter, in the illustrated article delivery box, as shown in FIG. 11, when there is an accessory Q such as a mouse or a power adapter, the accessory Q is mounted on the shelf 19 of the inner lid piece 15a. The product is stored in the product storage unit R. Then, as shown in FIG. 2, the outer cover piece 15b of the outer box A is folded over to close the accessory storage portion R, and finally the outer box A is sealed with an adhesive tape (not shown). As a result, the delivery article P is restrained and held without moving in the state of being sandwiched between the synthetic resin films 25 and 35 of the upper and lower inner boxes B and C in the hollow portion in the outer box A, Even if a vibration or impact is applied to the box A, the external force is packed by the upper and lower inner boxes B and C so as to be protected.

そこで、図示配送用箱には、上下内箱Ｂ・Ｃの合成樹脂フィルム２５・３５間で挟圧保持する配送用物品Ｐが、ノート型パソコンという金属製重量物であるので、下内箱Ｃの物品載置面部ｂに物品Ｐの比較的大きな荷重が加わることになる。しかし、本発明の配送用箱は、下内箱Ｃが、窓枠部２９と一体の側面板部２７・２８を、内壁片７２を巻き上げて形成される筒状な補強壁Ｗで補強すると共に、同じく窓枠部２９と一体の各コーナー部分５１をも、三角折曲板片５１ａ・５１ｂを折り重ねて形成される補強リブ５５で補強した構成であるため、配送時など、強い振動や衝撃が加わって、物品Ｐの重さで窓枠部２９が合成樹脂フィルム３５により引っ張られることがあっても、補強壁Ｗで補強した側板面部２７・２８や補強リブ５５で補強したコーナー部分５１で支えることにより（図２参照）、下内箱Ｃに引っ張り外力に対する強度を常に保持することができ、その結果、重量物の物品Ｐを合成樹脂フィルム２５・３５間で安定的に挟圧保持することができる。 Therefore, in the illustrated delivery box, the delivery article P that is sandwiched and held between the synthetic resin films 25 and 35 of the upper and lower inner boxes B and C is a heavy metal product called a notebook computer. A relatively large load of the article P is applied to the article placement surface portion b of the article. However, in the delivery box of the present invention, the lower inner box C reinforces the side plate portions 27 and 28 integrated with the window frame portion 29 with a cylindrical reinforcing wall W formed by winding up the inner wall piece 72. Similarly, each corner portion 51 integrated with the window frame portion 29 is also reinforced by the reinforcing rib 55 formed by folding the triangular folding plate pieces 51a and 51b, so that strong vibration and shock during delivery, etc. Even if the window frame portion 29 is pulled by the synthetic resin film 35 due to the weight of the article P, the corner portions 51 reinforced by the side plate surface portions 27 and 28 reinforced by the reinforcing walls W and the reinforcing ribs 55 are used. By supporting (see FIG. 2), it is possible to always maintain the strength against the tensile external force in the lower inner box C. As a result, the heavy article P is stably held between the synthetic resin films 25 and 35. be able to.

しかも、図示他例の配送用箱では、合成樹脂フィルム２５で物品Ｐを押える上内箱Ｂにも、４隅コーナー部分に補強部５６を形成して強度を高めた構成であるため、同様に振動や衝撃が加わって、物品Ｐの重さで窓枠部２３が合成樹脂フィルム２５により引っ張られることがあっても、各コーナーの補強リブ５６で支えて上内箱Ｂにも引っ張り外力に対する強度を常に保持させることができ、その結果、重量物の物品Ｐを合成樹脂フィルム２５・３５間で、より安定的に挟圧保持することができる。 In addition, in the delivery box of the other example shown in the figure, the upper inner box B that holds the article P with the synthetic resin film 25 is also configured to increase the strength by forming the reinforcing portions 56 at the four corner portions. Even if the window frame 23 is pulled by the synthetic resin film 25 due to the weight of the article P due to vibration or impact, it is supported by the reinforcing ribs 56 at each corner and the upper inner box B is also strong against the external force. As a result, the heavy article P can be held between the synthetic resin films 25 and 35 more stably.

また、図示例の物品配送用箱は、下内箱Ｃが隣り合う側面板部２７・２８間を分離せずに補強リブ５５をもった四隅コーナー部分５１で一体の矩形枠状に形付け、外箱Ａ内に嵌め込んだとき、各補強リブ５５を外箱Ａの底板部上に立てて矩形枠全体を支える構成であるため、外箱Ａ内で側面板部４６を内側に座屈させることなく、確実に且つスムーズに外箱Ａ内に嵌め入れることができる。 Further, the article delivery box of the illustrated example is shaped into an integral rectangular frame at the four corner portions 51 having the reinforcing ribs 55 without separating the side plate portions 27 and 28 adjacent to each other in the lower inner box C, When fitted in the outer box A, each reinforcing rib 55 is placed on the bottom plate portion of the outer box A to support the entire rectangular frame, and therefore the side plate 46 is buckled inward in the outer box A. Without being able to fit in the outer box A reliably and smoothly.

ところで、以上の図示例では、上内箱Ｂを、各コーナー部分４１にて三角折曲板片４１ａ・４１ｂが開かないように結合して矩形箱形の形態を維持させるために、上記した下内箱Ｃのように、切欠き穴６３に上側の掛止片６１を掛け止める連結手段によって各コーナー部４１の三角折曲板片４１ａ・４１ｂを連結する構成にすることもできる。反対に、下内箱Ｃを、各コーナー部５１にて三角折曲板片５１ａ・５１ｂが開かないように結合して矩形箱形の形態を維持させるために、上記上内箱Ｂのように、受け穴６６に留め片６５を嵌め込む連結手段によって各コーナー部５１の三角折曲板片５１ａ・５１ｂを連結する構成にすることもできる。 By the way, in the above illustrated example, the upper inner box B is connected to the corner portions 41 so that the triangular bent plate pieces 41a and 41b do not open, and the above-described lower inner box B is maintained in the rectangular box shape. As in the inner box C, the triangular bent plate pieces 41a and 41b of each corner portion 41 can be connected by connecting means for hooking the upper hooking piece 61 into the notch hole 63. On the contrary, in order to maintain the rectangular box shape by connecting the lower inner box C so that the triangular bent plate pieces 51a and 51b do not open at each corner 51, the upper inner box B is The triangular bent plate pieces 51a and 51b of each corner portion 51 can be connected by connecting means for fitting the retaining piece 65 into the receiving hole 66.
