Description
本発明は、上方から受ける荷重に応じて高さが変化する被包装物に好適な段ボール包装箱に関する。 The present invention relates to a corrugated cardboard packaging box suitable for an object to be packaged whose height changes according to a load received from above.
従来、四角筒状の胴部と、該胴部の上下を閉塞する蓋板とを備える段ボール包装箱においては、例えば、被包装物として合成樹脂製ボトルを包装することが行われる。 2. Description of the Related Art Conventionally, in a corrugated cardboard packaging box including a rectangular cylindrical body and a lid plate that closes the top and bottom of the body, for example, a synthetic resin bottle is packaged as an article to be packaged.
しかし、合成樹脂製ボトルは、上方からの荷重により高さが低くなるように変形するが、近年では、このときの変形量が許容範囲内であれば比較的大きく変形しても品質上問題が生じないものが多い。このため、合成樹脂製ボトルを包装した段ボール包装箱は、上方から荷重を受けると、高さが変化する合成樹脂製ボトルの変形に追従できず、胴膨れや座屈に伴う不規則な皺等の損傷部分が生じて外観が著しく低下する。 However, synthetic resin bottles are deformed so that the height is lowered by a load from above, but in recent years, there is a problem in quality even if the amount of deformation at this time is within an allowable range even if it is deformed relatively large. Many things do not occur. For this reason, the corrugated cardboard packaging box that wraps the synthetic resin bottle cannot follow the deformation of the synthetic resin bottle whose height changes when it receives a load from above, and has irregular folds or the like that accompany swelling or buckling. The damaged part is caused and the appearance is remarkably deteriorated.
そこで、胴部の一部に屈曲し易い部分を予め形成しておき、上方から荷重が付与されたときに、胴部の一部を積極的に全周にわたって屈曲させることにより、不規則な皺等の発生を抑えて外観低下を防止する包装箱が知られている（例えば、特許文献１、２参照）。 Therefore, by forming an easy-bending portion in a part of the body part in advance, when a load is applied from above, the part of the body part is actively bent over the entire circumference, thereby causing irregular A packaging box that suppresses the occurrence of the above and prevents the appearance deterioration is known (see, for example, Patent Documents 1 and 2).
しかし、従来のように胴部の一部に屈曲し易い部分を予め形成しても、胴部の角部においては屈曲変形を吸収することはできず、胴部の角部に不規則な皺が生じるために、外観上は潰れと同等の印象を与えてしまう不都合がある。 However, even if a portion that is easy to bend is formed in advance on a part of the body as in the prior art, the bending deformation cannot be absorbed in the corner of the body, and irregular corners are not formed in the corner of the body. Therefore, there is an inconvenience that an appearance equivalent to crushing is given.
上記の点に鑑み、本発明は、上方から荷重を受けたときの被包装物の高さの変化に確実に追従させることができるだけでなく、胴部に不規則な皺等を発生させることなく良好な外観を維持することができる段ボール包装箱を提供することを目的とする。 In view of the above points, the present invention can not only surely follow the change in the height of the article to be packaged when receiving a load from above, but also without generating irregular wrinkles or the like in the body portion. An object of the present invention is to provide a cardboard packaging box that can maintain a good appearance.
かかる目的を達成するために、本発明は、上方から受ける荷重に応じて高さが変化する被包装物を包装する段ボール包装箱であって、多角筒状の胴部と、該胴部の上下を閉塞する蓋板とを備え、前記胴部は、水平方向に延びる帯状の屈曲可能部を備え、上方から付与される荷重に応じて前記屈曲可能部が胴部の内方に突出するように屈曲するものにおいて、前記屈曲可能部は、前記胴部の角部を開放する開放部を介して不連続に設けられていることを特徴とする。 In order to achieve such an object, the present invention provides a cardboard packaging box for packaging an article to be packaged whose height changes in accordance with a load received from above, and includes a polygonal cylindrical body and upper and lower parts of the body. And the body includes a belt-shaped bendable portion extending in the horizontal direction so that the bendable portion protrudes inward of the body according to a load applied from above. In the bending portion, the bendable portion is discontinuously provided through an opening portion that opens a corner portion of the body portion.
本発明の屈曲可能部は、前記胴部の角部を開放する開放部を介して不連続であることにより、胴部の角部を除く各周壁面に設けられている。そして、蓋板上から下方に向って荷重を受けると、蓋板に押圧された被包装物の高さの変化に追従して屈曲可能部が屈曲する。これにより、角部を除く各周壁面は、屈曲可能部によって歪が吸収され、不規則な皺等の発生が防止される。そして、本発明によれば、前記開放部を設けたことによって、胴部の内方に向って突出するように屈曲した屈曲可能部が胴部の角部で干渉することがなく、屈曲動作が円滑に行われるようにすることができると共に、胴部の角部における皺等の発生を確実に防止することができる。従って、本発明の段ボール包装箱によれば、胴部に不規則な皺等を発生させることなく良好な外観を維持することができる。 The bendable part of the present invention is provided on each peripheral wall surface excluding the corner part of the trunk part by being discontinuous through an opening part that opens the corner part of the trunk part. When a load is received downward from the top of the cover plate, the bendable portion bends following the change in the height of the article to be package pressed against the cover plate. Thereby, distortion is absorbed by each bendable wall part except a corner | angular part by a bendable part, and generation | occurrence | production of irregular wrinkles etc. is prevented. According to the present invention, since the opening portion is provided, the bendable portion bent so as to protrude inward of the trunk portion does not interfere with the corner portion of the trunk portion, and the bending operation is performed. While being able to be performed smoothly, generation | occurrence | production of the wrinkles etc. in the corner | angular part of a trunk | drum can be prevented reliably. Therefore, according to the corrugated cardboard packaging box of the present invention, it is possible to maintain a good appearance without causing irregular wrinkles or the like in the body portion.
また、本発明において、前記屈曲可能部は、互いに平行に形成された一対の第１折曲げ可能線と、両第１折曲げ可能線間の中央に沿って形成されて第１折曲げ可能線の折り曲げ方向と反対方に折り曲げられる第２折曲げ可能線とを備え、各折曲げ可能線は、復元力をもって弾発的に折曲げ可能とされていることを特徴とする。 In the present invention, the bendable portion is formed along a center between a pair of first bendable lines formed in parallel to each other and the first bendable lines. And a second foldable line that is bent in a direction opposite to the bending direction of each of the foldable lines. Each foldable line is elastically foldable with a restoring force.
これによれば、上方から胴部に付与される荷重により屈曲可能部が屈曲するとき、各折曲げ可能線が折り曲げられる際に生じる弾性力を上方からの荷重に抗して作用させることができるので、被包装物に付与される荷重を軽減することができる。よって、被包装物を確実に保護して良好な包装状態を維持することができる。 According to this, when the bendable portion is bent by the load applied to the body portion from above, the elastic force generated when each bendable line is bent can be made to act against the load from above. As a result, the load applied to the package can be reduced. Therefore, it is possible to reliably protect the package and maintain a good packaging state.
また、このとき、前記第２折曲げ可能線は、前記胴部を貫通する孔部を介して不連続に設けられていることが好ましい。これによれば、孔部の大きさ或いは孔部の数によって屈曲可能部が屈曲する際に第２折曲げ可能線の折曲げ弾性を調節することができる。 At this time, it is preferable that the second bendable line is provided discontinuously through a hole passing through the body. According to this, when the bendable part bends according to the size of the hole part or the number of the hole parts, the bending elasticity of the second bendable line can be adjusted.
本発明の一実施形態を図面に基づいて説明する。本実施形態の包装箱１は、図１に組立状態を示すように、四角筒状の胴部２と、該胴部２の上端を閉塞する天蓋板３（蓋板）と、該胴部２の下端を閉塞する底蓋板４（蓋板）とによって直方体状に形成されている。 An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the packaging box 1 of the present embodiment includes a rectangular cylindrical body 2, a canopy plate 3 (cover plate) that closes the upper end of the body 2, and the body 2. And a bottom lid plate 4 (lid plate) that closes the lower end of the rectangular parallelepiped.
包装箱１の胴部２内には複数の合成樹脂製（例えばポリエチレンテレフタレート製）ボトルＷ（図５に一部を示す）が被包装物として収容される。 A plurality of synthetic resin (for example, polyethylene terephthalate) bottles W (a part of which is shown in FIG. 5) are accommodated in the body 2 of the packaging box 1 as packages.
包装箱１は、図２に展開して示すように、一枚の段ボール板紙１ａから形成されている。なお、図２は、段ボール板紙１ａの裏面側を示している。段ボール板紙１ａは、第１側板５と、第１側板５の一側縁に折目線を介して連設された第２側板６と、第２側板６の一側縁に折目線を介して連設された第３側板７と、第３側板７の一側縁に折目線を介して連設された第４側板８とを備えている。更に、第１側板５の他側縁には折目線を介して接着片９が連設されている。 The packaging box 1 is formed from a piece of corrugated paperboard 1a as shown in FIG. FIG. 2 shows the back side of the corrugated paperboard 1a. The corrugated paperboard 1a includes a first side plate 5, a second side plate 6 connected to one side edge of the first side plate 5 via a fold line, and a side edge of the second side plate 6 connected to the one side edge via a fold line. A third side plate 7 provided and a fourth side plate 8 connected to one side edge of the third side plate 7 via a crease line are provided. Further, an adhesive piece 9 is continuously provided on the other side edge of the first side plate 5 via a crease line.
各側板５，６，７，８の夫々の上端縁には、折目線を介して天蓋フラップ１０，１１，１２，１３が連設されている。また、各側板５，６，７，８の夫々の下端縁には、折目線を介して底蓋フラップ１４，１５，１６，１７が連設されている。後述するが、天蓋フラップ１０，１１，１２，１３は天蓋板３を構成するものであり、底蓋フラップ１４，１５，１６，１７は底蓋板４を構成するものである。 Canopy flaps 10, 11, 12, and 13 are connected to upper end edges of the side plates 5, 6, 7, and 8 through fold lines. Further, bottom lid flaps 14, 15, 16, and 17 are connected to lower end edges of the side plates 5, 6, 7, and 8 through crease lines. As will be described later, the canopy flaps 10, 11, 12, and 13 constitute the canopy plate 3, and the bottom lid flaps 14, 15, 16, and 17 constitute the bottom lid plate 4.
接着片９、第１側板５、第２側板６、第３側板７、及び第４側板８には、帯状の屈曲可能部１８が設けられている。屈曲可能部１８は、各側板５，６，７，８の夫々の上端縁から所定距離を存した下方に位置し、図１に示すように水平方向に延びる。 The adhesive piece 9, the first side plate 5, the second side plate 6, the third side plate 7, and the fourth side plate 8 are provided with strip-shaped bendable portions 18. The bendable portion 18 is positioned below a predetermined distance from the upper edge of each of the side plates 5, 6, 7, and 8, and extends in the horizontal direction as shown in FIG.
屈曲可能部１８は、図２に示すように、互いに平行に形成された一対の第１折曲げ可能線１９，２０と、両第１折曲げ可能線１９，２０間の中央に沿って形成された第２折曲げ可能線２１とを備えている。第２折曲げ可能線２１は、屈曲可能部１８を上部屈曲片１８ａと下部屈曲片１８ｂとに区分している。 As shown in FIG. 2, the bendable part 18 is formed along a pair of first foldable lines 19 and 20 formed in parallel to each other and the center between the first foldable lines 19 and 20. The second foldable wire 21 is provided. The second bendable line 21 divides the bendable portion 18 into an upper bend piece 18a and a lower bend piece 18b.
第１折曲げ可能線１９，２０は、段ボール板紙１ａの裏ライナ及び中芯を潰すようにして形成され、これによって、上部屈曲片１８ａと下部屈曲片１８ｂとが胴部２の内側に折り曲げられるように折り曲げ方向を案内している。第２折曲げ可能線２１は、段ボール板紙１ａの表ライナ及び中芯を潰すようにして形成され、上部屈曲片１８ａと下部屈曲片１８ｂとが互いに重合するように折り曲げ方向を案内している。これにより、後述するが、屈曲可能部１８の屈曲状態は、図３に示すように、包装箱１の外側から見て谷折り状に屈曲する。 The first foldable lines 19 and 20 are formed so as to crush the back liner and the center core of the corrugated paperboard 1 a, whereby the upper bent piece 18 a and the lower bent piece 18 b are bent inside the body portion 2. The bending direction is guided as follows. The second bendable line 21 is formed by crushing the front liner and the center core of the corrugated paperboard 1a, and guides the folding direction so that the upper bent piece 18a and the lower bent piece 18b overlap each other. Thereby, as will be described later, the bending state of the bendable portion 18 is bent in a valley shape as seen from the outside of the packaging box 1 as shown in FIG.
また、屈曲可能部１８は、図２に示すように、４つの開放部２２によって不連続に設けられた状態となっている。即ち、開放部２２は、第１側板５と第２側板６の境界位置、第２側板６と第３側板７の境界位置、第３側板７と第４側板８の境界位置、接着片９と第１側板５との境界位置（組立後、第１側板５と第４側板８の境界位置）に夫々形成されている。そして、各開放部２２は、図１に示すように、組立状態の包装箱１における４つの角部を夫々開放する。 In addition, the bendable portion 18 is discontinuously provided by the four open portions 22 as shown in FIG. That is, the open portion 22 includes a boundary position between the first side plate 5 and the second side plate 6, a boundary position between the second side plate 6 and the third side plate 7, a boundary position between the third side plate 7 and the fourth side plate 8, and the adhesive piece 9. It is formed at the boundary position with the first side plate 5 (after the assembly, the boundary position between the first side plate 5 and the fourth side plate 8). Then, as shown in FIG. 1, each open part 22 opens four corners in the assembled packaging box 1.
第２折曲げ可能線２１は、図２に示すように、互いに間隔を存して直線状に並ぶ孔部２３により不連続となっている。なお、第２側板６の屈曲可能部１８と第４側板８の屈曲可能部１８とに設けられている孔部２３は、他の孔部２３に比べて大きく開口した形状に形成されていることにより、把持部として用いることができるようになっている。 As shown in FIG. 2, the second bendable line 21 is discontinuous by holes 23 arranged in a straight line at intervals. In addition, the hole 23 provided in the bendable part 18 of the second side plate 6 and the bendable part 18 of the fourth side plate 8 is formed in a shape having a large opening as compared with the other hole parts 23. Therefore, it can be used as a gripping part.
第１折曲げ可能線１９，２０及び第２折曲げ可能線２１は、段ボール板紙１ａが有する復元弾性により弾発的に折り曲げられるが、孔部２３の数や大きさによって第２折曲げ可能線２１の折り曲げ時の復元弾性が適度に調節されている。 The first bendable lines 19 and 20 and the second bendable line 21 are elastically bent by the restoring elasticity of the corrugated paperboard 1 a, but the second bendable lines depend on the number and size of the holes 23. The restoring elasticity at the time of bending 21 is moderately adjusted.
図１に示す包装箱１は、図２に示す上記構成の段ボール板紙１ａから組み立てられる。即ち、段ボール板紙１ａの各側板５，６，７，８を夫々折目線に沿って同一方向に折り曲げ、次いで、第１側板５の端縁に連設されている接着片９を第４側板８の端部の内側面に重合させて接着する。これにより、四角筒状の胴部２が形成される。 The packaging box 1 shown in FIG. 1 is assembled from the corrugated paperboard 1a having the above-described configuration shown in FIG. That is, the side plates 5, 6, 7 and 8 of the corrugated cardboard 1a are bent in the same direction along the crease line, respectively, and then the adhesive piece 9 connected to the edge of the first side plate 5 is connected to the fourth side plate 8 It is made to polymerize and adhere to the inner surface of the end portion of the. Thereby, the square cylinder-shaped trunk | drum 2 is formed.
続いて、各底蓋フラップ１４，１５，１６，１７を各折目線に沿って水平に折り曲げ、各底蓋フラップ１４，１５，１６，１７の重合部分を接着剤で接着することにより、底蓋板４が形成される。そして、胴部２の内部に被包装物（本実施形態においては複数本の合成樹脂製ボトルＷ）を入れる。その後、各天蓋フラップ１０，１１，１２，１３を各折目線に沿って水平に折り曲げ、各天蓋フラップ１０，１１，１２，１３の重合部分を接着剤で接着することにより、天蓋板３が形成され、図１に示すように、包装箱１が形成される。 Subsequently, the bottom lid flaps 14, 15, 16, and 17 are horizontally folded along the fold lines, and the overlapping portions of the bottom lid flaps 14, 15, 16, and 17 are adhered with an adhesive, thereby allowing the bottom lids to be bonded. A plate 4 is formed. Then, an article to be packaged (in the present embodiment, a plurality of synthetic resin bottles W) is placed inside the body portion 2. Thereafter, the canopy flaps 10, 11, 12, and 13 are horizontally bent along the fold lines, and the overlapped portions of the canopy flaps 10, 11, 12, and 13 are bonded with an adhesive, whereby the canopy plate 3 is formed. As shown in FIG. 1, a packaging box 1 is formed.
次に、本実施形態の包装箱１の使用状態について、図１、図３、図４、図５の各図を参照して説明する。 Next, the use state of the packaging box 1 of this embodiment is demonstrated with reference to each figure of FIG.1, FIG.3, FIG.4 and FIG.
包装箱１は、図１の状態で例えば輸送や保管時に積み重ねられる等により上方から荷重がかかる場合がある。この荷重によって、包装箱１は、図３に示すように、胴部２の全周にわたり、屈曲可能部１８が復元力をもって弾発的に屈曲するようになっている。このとき、屈曲した屈曲可能部１８は、図４に示すように、胴部２の内方に向って突出するが、各側板５，６（７，８）からその内側に突出した屈曲可能部１８は、開放部２２によって角部で干渉することなく、円滑に屈曲する。これにより、屈曲した屈曲可能部１８が胴部２の角部で不規則な皺等を形成することなく、図３に示すように、包装箱１として良好な外観が維持される。 The packaging box 1 may be loaded from above by being stacked in the state shown in FIG. With this load, as shown in FIG. 3, the bendable portion 18 of the packaging box 1 is elastically bent with a restoring force over the entire circumference of the body portion 2. At this time, as shown in FIG. 4, the bent bendable portion 18 protrudes inward of the body portion 2, but the bendable portion protrudes inward from the side plates 5, 6 (7, 8). 18 bends smoothly without interference at the corners by the opening 22. As a result, the bent bendable portion 18 does not form irregular wrinkles or the like at the corners of the body portion 2, and the good appearance of the packaging box 1 is maintained as shown in FIG.
ところで、包装箱１の内部には、図５（ａ）に示すように、合成樹脂製ボトルＷが包装されている。包装箱１の上方から荷重がかかると、この荷重は、天蓋板３を介して合成樹脂製ボトルＷに付与される。近年の合成樹脂製ボトルＷは、上方から荷重を受けるとその高さを縮小させる方向に柔軟に変形し、荷重の付与が解除されると元の形状に復元するようになってる。 Incidentally, a synthetic resin bottle W is packaged inside the packaging box 1 as shown in FIG. When a load is applied from above the packaging box 1, this load is applied to the synthetic resin bottle W via the canopy plate 3. A recent synthetic resin bottle W is deformed flexibly in the direction of reducing its height when it receives a load from above, and is restored to its original shape when the application of the load is released.
そして、本実施形態の包装箱１は、図５（ｂ）に示すように、合成樹脂製ボトルＷが荷重を受けて高さが縮小するように変形すると、胴部２の屈曲可能部１８が屈曲して合成樹脂製ボトルＷの高さの変化に追従する。これにより、図３に示すように、屈曲可能部１８以外の胴部２の外面に不規則な皺等が発生することはない。 And if the packaging box 1 of this embodiment deform | transforms so that synthetic resin bottle W may receive a load and height may reduce, as shown in FIG.5 (b), the bendable part 18 of the trunk | drum 2 will become. Bends to follow the change in height of the synthetic resin bottle W. Thereby, as shown in FIG. 3, irregular wrinkles etc. do not generate | occur | produce on the outer surface of the trunk | drum 2 other than the bendable part 18. FIG.
その後、包装箱１への荷重の付与が解除されると、屈曲可能部１８がその弾性により復元する。これにより、合成樹脂製ボトルＷが元の形状に復元する動作を阻害することなく、図１に示す状態となる。これにより、包装箱１は、良好な外観が維持される。 Thereafter, when the application of the load to the packaging box 1 is released, the bendable portion 18 is restored by its elasticity. Thereby, it will be in the state shown in FIG. 1 without inhibiting the operation | movement which the synthetic resin bottle W restore | restores to the original shape. Thereby, the packaging box 1 maintains a good appearance.
更に、本実施形態の包装箱１においては、図５（ｂ）に示すように、屈曲可能部１８が、合成樹脂製ボトルＷの上部に形成されている小径部分２４に対応する位置に配設されている。合成樹脂製ボトルＷの小径部分２４は、口部とその下方に連続する上端部に形成されている。そして、合成樹脂製ボトルＷの小径部分２４に対応する包装箱１の胴部２の内部においては、比較的大きな空間が形成される。そこで、屈曲可能部１８を、胴部２における合成樹脂製ボトルＷの小径部分２４に対応する位置に設けることで、胴部２の内方に突出して屈曲状態となる屈曲可能部１８を、合成樹脂製ボトルＷの小径部分２４の周囲に形成される空間に収容することができる。よって、屈曲する屈曲可能部１８と合成樹脂製ボトルＷとの干渉が防止でき、屈曲可能部１８の屈曲動作を円滑に行わせることができる。 Furthermore, in the packaging box 1 of the present embodiment, the bendable portion 18 is disposed at a position corresponding to the small diameter portion 24 formed on the upper portion of the synthetic resin bottle W, as shown in FIG. Has been. The small diameter portion 24 of the synthetic resin bottle W is formed at the mouth portion and the upper end portion continuous below the mouth portion. A relatively large space is formed inside the trunk portion 2 of the packaging box 1 corresponding to the small diameter portion 24 of the synthetic resin bottle W. Therefore, by providing the bendable portion 18 at a position corresponding to the small diameter portion 24 of the synthetic resin bottle W in the body portion 2, the bendable portion 18 that protrudes inward of the body portion 2 and is in a bent state is synthesized. The resin bottle W can be accommodated in a space formed around the small diameter portion 24. Therefore, interference between the bendable bendable portion 18 and the synthetic resin bottle W can be prevented, and the bendable portion 18 can be smoothly bent.
なお、本実施形態においては、被包装物として合成樹脂製ボトルＷを挙げたが、これに限るものではく、上方から受ける荷重に応じて高さが変化する被包装物であれば好適に包装することができる。この場合、被包装物が他部より小径の部分を備えていれば、胴部２において当該小径部分に対応する位置に屈曲可能部１８を設けることが好ましい。 In the present embodiment, the synthetic resin bottle W is cited as the packaged object, but the present invention is not limited to this, and any packaged article whose height changes according to the load received from above can be suitably packaged. can do. In this case, if the article to be packaged has a portion having a smaller diameter than the other portion, it is preferable to provide the bendable portion 18 at a position corresponding to the small diameter portion in the body portion 2.
また、本実施形態においては、第２側板６の屈曲可能部１８と第４側板８の屈曲可能部１８とに設けられている孔部２３を把持部として用いるものを示したが、これに限るものではなく、第２側板６の屈曲可能部１８と第４側板８の屈曲可能部１８とに設けられている孔部２３は、第１側板５の屈曲可能部１８と第３側板７の屈曲可能部１８とに設けられている孔部２３と同一の形状とし、複数形成してもよい。 Moreover, in this embodiment, although what used the hole 23 provided in the bendable part 18 of the 2nd side plate 6 and the bendable part 18 of the 4th side plate 8 as a holding part was shown, it does not restrict to this Instead, the hole 23 provided in the bendable portion 18 of the second side plate 6 and the bendable portion 18 of the fourth side plate 8 is bent by the bendable portion 18 of the first side plate 5 and the third side plate 7. A plurality of holes 23 may be formed in the same shape as the hole 23 provided in the possible portion 18.
