Description

本発明は、梱包箱と、該梱包箱の底部に被梱包物と一緒に収容され、被梱包物を設置させるためのパレットとから成る段ボール製梱包箱装置に関するものである。 The present invention relates to a corrugated cardboard packaging box device comprising a packaging box and a pallet for placing the packaged object in the bottom of the packaging box together with the packaged object.

従来の技術を説明するに当り、本発明の図面を援用する。被梱包物を梱包するために、段ボールから成るパレットが公知であり、各種の特許出願がされている（例えば、特許文献１参照）。図１及び図２に示されるように、パレットＰは、被梱包物Ｄを設置するためのパレット板１と、フォークリフト爪Ｎを挿入させるために、前記パレット板１を所定高さだけ持ち上げて爪挿入空間Ｖを形成するための複数本の桁材２より構成されている。 In describing the prior art, the drawings of the present invention are incorporated. In order to pack an object to be packed, a pallet made of corrugated cardboard is known and various patent applications have been filed (for example, see Patent Document 1). As shown in FIG. 1 and FIG. 2, the pallet P has a claw by lifting the pallet plate 1 by a predetermined height in order to insert the pallet plate 1 for installing the article D to be packed and the forklift claw N. It comprises a plurality of girders 2 for forming the insertion space V.

前記パレットＰを梱包箱Ｃ₁の底部に収容し、その状態のパレットＰに被梱包物Ｄを設置させる構成の段ボール製梱包箱装置Ａ₁が公知である。この場合、梱包箱Ｃ₁に収容されたパレットＰに被梱包物Ｄを設置した後、梱包箱Ｃ₁の上板をシール等で止めるだけで済む。また、複数個の被梱包物Ｄを設置させる「集合梱包」の場合であっても、被梱包物ＤとパレットＰとを結束バンド等で締める作業が不要である。更に、被梱包物Ｄが視認不能になるため、盗難等のおそれも少ない。 A corrugated cardboard packaging box device A ₁ having a configuration in which the pallet P is accommodated in the bottom of the packaging box C _{1 and} the article D to be packed is installed on the pallet P in that state is known. In this case, after the setting of the object to be packed D to the pallet P accommodated in the packing box C _1, it requires only the top plate of the packaging box C ₁ just stopped at the seal or the like. Further, even in the case of “collective packing” in which a plurality of objects to be packed D are installed, it is not necessary to tighten the objects to be packed D and the pallet P with a binding band or the like. Furthermore, since the packaged item D becomes invisible, there is little risk of theft.

従来のパレットは、パレット板と各桁材とが糊等の接着剤によって一体に固着されている。このため、パレットを保管するために大きなスペースを必要とする。また、被梱包物の大きさに応じて、複数種類のパレットと梱包箱とを用意しておかなければならず、梱包現場において被梱包物の大きさが突然変更された場合に対応できないおそれがある。更に、接着剤が飛散・落下する等により、梱包現場が汚損されるという不具合もある。 In the conventional pallet, the pallet plate and each girder are fixed integrally with an adhesive such as glue. For this reason, a large space is required to store the pallet. In addition, depending on the size of the item to be packed, multiple types of pallets and packing boxes must be prepared, and there is a risk that it will not be possible if the size of the item to be packed is suddenly changed at the packing site. is there. Further, there is a problem that the packing site is soiled due to the scattering and dropping of the adhesive.

図１１及び図１２に示されるように、被梱包物ＤをパレットＰに設置するときの作業を容易にするため、上箱と下箱に分離させた梱包箱Ｃ₂を使用する構成の段ボール製梱包箱装置Ａ₂も存している。従来の段ボール製梱包箱装置では、下箱に上箱を単に被せるだけの構成であるため、搬送途中において不正に梱包解除されるおそれがある。これを防止するため、結束バンド等により上箱と下箱とを分離不能に縛らなければならず、梱包作業に手間がかかっている。
特開２００２−２７４５３８号公報 As shown in FIG. 11 and FIG. 12, in order to facilitate the work when the article to be packaged D is placed on the pallet P, the product is made of corrugated cardboard so that the packaging box C ₂ separated into the upper box and the lower box is used. packing box device A ₂ is also exist. Since the conventional corrugated cardboard packaging box device has a configuration in which the upper box is simply put on the lower box, there is a possibility that the packing is illegally released during the conveyance. In order to prevent this, it is necessary to bind the upper box and the lower box in an inseparable manner with a binding band or the like, which takes time for packing work.

次に、桁材２について説明する。図２ないし図４に示されるように、桁材２は、所定の板厚ｔ₁を有する長方形状の段ボール板を各折曲げ線４（図４参照）で折り曲げて角筒状に形成すると共に、内側に複数個（本実施例の場合、３個）の支持部材５（図８参照）を配置したものである。図４に示されるように、展開状態の桁材２の一端部（図４の図面視における右端部）には、折曲げ状態でパレット板１の底面部に接合される天井板部６が形成されていて、該天井板部６には、パレット板１の各係止爪３と同一形状の各係止爪７が、各係止爪群Ｂ₁〜Ｂ₅に対応して（即ち、桁材２の長手方向に一定の取付間隔Ｌ₁をおいて）設けられている。各係止爪７は、天井板部６の端縁部６ａから、距離Ｊ₁だけ離れた位置に設けられている。そして、前記天井板部６に隣接して第１側板部８、底板部９、第２側板部１１、及び折曲げ状態で前記天井板部６の直下に配置される折返し板部１２が順に形成されている。図４及び図６に示されるように、上記した各板部６，８，９，１１，１２の幅を順にＫ₁〜Ｋ₅とすると、天井板部６の幅Ｋ₁と底板部９の幅Ｋ₃はほぼ同一であり、第２側板部１１の幅Ｋ₄は、第１側板部８の幅Ｋ₂よりも板厚ｔ₁の分だけ狭い。また、折返し板部１２の幅Ｋ₅は、天井板部６の幅Ｋ₁よりも僅かに狭い。この結果、各板部６，８，９，１１，１２が折り曲げられて桁材２が形成されたとき、図６に示されるように、その断面形状は長方形状を呈すると共に、折返し板部１２の端縁部１２ａは、第１側板部８の内側面よりも僅かに離れて配置される。そして、前記第１側板部８の幅Ｋ₂(即ち、折曲げ状態における各桁材２の高さ）は、フォークリフト爪Ｎの厚みよりも広い。 Next, the girder 2 will be described. As shown in FIGS. 2 to 4, the girder 2 is formed in a rectangular tube shape by bending a rectangular corrugated board having a predetermined thickness t _{1 along} each folding line 4 (see FIG. 4). A plurality (three in the case of this embodiment) of support members 5 (see FIG. 8) are arranged inside. As shown in FIG. 4, a ceiling plate portion 6 that is joined to the bottom surface portion of the pallet plate 1 in a bent state is formed at one end portion (the right end portion in the drawing view of FIG. 4) of the deployed beam member 2. In the ceiling plate portion 6, each locking claw 7 having the same shape as each locking claw 3 of the pallet plate 1 corresponds to each locking claw group B _{1 to} B ₅ (that is, a girder). A fixed mounting interval L ₁ is provided in the longitudinal direction of the material 2. Each locking claw 7 is provided at a position separated from the end edge 6 a of the ceiling plate 6 by a distance J ₁ . Then, a first side plate portion 8, a bottom plate portion 9, a second side plate portion 11, and a folded plate portion 12 disposed immediately below the ceiling plate portion 6 in a folded state are sequentially formed adjacent to the ceiling plate portion 6. Has been. As shown in FIG. 4 and FIG. 6, when the widths of the plate parts 6, 8, 9, 11, and 12 are K _{1 to} K ₅ in order, the width K ₁ of the ceiling plate part 6 and the bottom plate part 9 The width K ₃ is substantially the same, and the width K ₄ of the second side plate portion 11 is narrower than the width K ₂ of the first side plate portion 8 by the plate thickness t ₁ . Further, the width K ₅ of the folded plate portion 12 is slightly narrower than the width K ₁ of the ceiling plate portion 6. As a result, when the girders 2 are formed by bending the plate portions 6, 8, 9, 11, and 12, the cross-sectional shape thereof is rectangular as shown in FIG. The end edge portion 12 a is disposed slightly apart from the inner surface of the first side plate portion 8. The width K ₂ of the first side plate portion 8 (that is, the height of each beam 2 in the bent state) is wider than the thickness of the forklift pawl N.

図４ないし図６に示されるように、前記折返し板部１２において、天井板部６の各係止爪７と対応する位置（第２側板部１１と折返し板部１２との間の折曲げ線４から距離Ｊ₂だけ離れた位置）には、各係止爪７を挿入係止させるための各係止孔用開口１３が設けられている。図５の（イ）に示されるように、各係止孔用開口１３の抜き孔形状は、各係止爪７の外形状に対応していて、各係止孔用開口１３の内幅は、各係止爪７の幅Ｗ₁,Ｗ₂と同一であるが、長さＷ₄は、各係止爪７の長さＷ₃よりも少し長い。図５の（ロ）に示されるように、展開状態の桁材２が折り曲げられて角筒状に形成されると、天井板部６の直下に、折返し板部１２が重なり状態で配置される。ここで、各係止孔用開口１３が形成される距離Ｊ₂は、前述した各係止爪７が形成される距離Ｊ₁よりも少し短い。このため、天井板部６の各係止爪７と、折返し板部１２の各係止孔用開口１３とは、距離ｅ（ｅ＝Ｊ₁−Ｊ₂−ｔ₁)だけずれて配置される。 As shown in FIGS. 4 to 6, in the folded plate portion 12, positions corresponding to the respective locking claws 7 of the ceiling plate portion 6 (fold lines between the second side plate portion 11 and the folded plate portion 12 are arranged. (Positions separated by distance J ₂ ) are provided with respective locking hole openings 13 for inserting and locking the respective locking claws 7. As shown in FIG. 5A, the hole shape of each locking hole opening 13 corresponds to the outer shape of each locking claw 7, and the inner width of each locking hole opening 13 is Although the widths W ₁ and W _{2 of} the respective locking claws 7 are the same, the length W ₄ is slightly longer than the length W ₃ of the respective locking claws 7. As shown in (b) of FIG. 5, when the girders 2 in the unfolded state are folded and formed into a rectangular tube shape, the folded plate portion 12 is arranged in an overlapping state immediately below the ceiling plate portion 6. . Here, the distance J ₂ at which each locking hole opening 13 is formed is slightly shorter than the distance J ₁ at which each locking claw 7 is formed. Accordingly, each locking claw 7 of the ceiling plate portion 6, and the latching hole opening 13 of the folded plate portion 12, the distance _{_{e (e = J 1 -J 2}} -t 1) is arranged displaced by .

図６及び図７に示されるように、各係止爪７の接続部７ａを支点として、各係止爪７を下方にほぼ直角に折り曲げると、各係止爪７が対応する折返し板部１２の各係止孔用開口１３に入り込む。各係止爪７と各係止孔用開口１３の幅Ｗ₁は同一であるものの、両者の位置は幅方向に距離ｅだけずれている。このため、係止爪７が折り曲げられるとき、該係止爪７の一端部７ｂ（図６の図面視における右端部）は、折返し板部１２の端縁部１２ａを側方（第１側板部８の側）に移動させながら係止孔用開口１３に入り込む。そして、各係止爪７の接続部７ａが、各係止孔用開口１３において切込み幅が狭くなっている部分（狭幅部１３ａ）に入り込むことにより、前記折返し板部１２は戻される。これにより、各係止爪７の抜け止めが図られ、桁材２は折曲げ状態（角筒状態）で保持される。そして、この状態で、桁材２の係止爪７が折り曲げられた部分には、幅Ｗ₅（Ｗ₅＝Ｗ₁−ｅ）の係止孔２０が形成される（図６参照）。 As shown in FIGS. 6 and 7, when each latching claw 7 is bent downward at a substantially right angle with the connection portion 7 a of each latching claw 7 as a fulcrum, the folded plate portion 12 to which each latching claw 7 corresponds. It enters into each of the locking hole openings 13. Although each locking claw 7 and each locking hole opening 13 have the same width W ₁ , their positions are shifted by a distance e in the width direction. For this reason, when the latching claw 7 is bent, one end portion 7b of the latching claw 7 (the right end portion in the drawing view of FIG. 6) is located laterally (first side plate portion) of the end edge portion 12a of the folded plate portion 12. 8 is moved into the engagement hole opening 13 while being moved. And the connection part 7a of each latching claw 7 enters into the part (narrow width part 13a) where the cutting width is narrow in each opening 13 for latching holes, and the said folding | turning board part 12 is returned. Thereby, each latching claw 7 is prevented from coming off, and the girder 2 is held in a bent state (square tube state). In this state, a locking hole 20 having a width W ₅ (W ₅ = W ₁ -e) is formed in the bent portion of the locking claw 7 of the girder 2 (see FIG. 6).

次に、支持部材５について説明する。図７及び図８に示されるように、各桁材２の内部には、高さ方向の強度を確保するために、３個の支持部材５が配置されている。本実施例の支持部材５は、所定厚の段ボール板を複数回に亘って巻回して角筒状にしたものであり、軸心方向を高さ方向に沿わせて、各桁材２における各係止爪７及び各係止孔用開口１３の直下に配置される。各支持部材５の高さは、桁材２の内側高さにほぼ等しい。これにより、各桁材２は、第１及び第２の各側板部８，１１と各支持部材５とでもって被梱包物Ｄの荷重を支持する。また、各係止爪７が下方に折り曲げられたとき、それらの大部分が、対応する支持部材５の内側部分（中空部分）に入り込む。これにより、各支持部材５が桁材２から抜け出るおそれはない。 Next, the support member 5 will be described. As shown in FIGS. 7 and 8, three support members 5 are arranged in each girder 2 in order to ensure strength in the height direction. The support member 5 of the present embodiment is formed by winding a corrugated board of a predetermined thickness a plurality of times into a rectangular tube shape, and the axial direction of the corrugated board 2 is set along the height direction. It arrange | positions directly under the latching claw 7 and each opening 13 for latching holes. The height of each support member 5 is substantially equal to the inner height of the girder 2. Thereby, each girder 2 supports the load of the article D to be packed with the first and second side plate portions 8 and 11 and the support members 5. Moreover, when each latching nail | claw 7 is bent below, most of them enter the inner part (hollow part) of the corresponding support member 5. FIG. Thereby, there is no possibility that each support member 5 will come out of the girder 2.

図６ないし図８に示されるように、折り曲げられて角筒状に保持され、内部に各支持部材５が配置された桁材２とパレット板１とが一体に取付けられる。即ち、パレット板１の底面部に各桁材２が配置された状態で、前記パレット板１に設けられた各係止爪３が下方に折り曲げられる。各係止爪３は、対応する桁材２の係止孔用開口１３に入り込む。このとき、前記各係止爪３は、桁材２における天井板部６の係止爪７と殆ど同一の作用でもって、桁材２の係止孔２０に入り込む。パレット板１の係止爪３の幅Ｗ₁は、係止孔２０の幅Ｗ₅よりも大きいので、該係止爪１３の一端部３ｂ（図６の図面視における右端部）が、折返し板部１２の端縁部１２ａを側方（第１側板部８の側）に移動させると共に、他端部３ｃが桁材２の天井板部６を反対側の側方（第２側板部１１の側）に移動させながら係止孔２０に入り込む。そして、各係止爪３の接続部３ａが、各係止孔２０において切込み幅が狭くなっている部分（狭幅部１３ａ）に単独で、或いは桁材２の係止爪７と重なって入り込むことにより、前記折返し板部１２は戻される。これにより、各係止爪３の抜け止めが図られ、パレット板１と桁材２とが一体に取付けられる。パレット板１の各係止爪３を逆方向に折り曲げて戻すことにより、パレット板１と桁材２とを容易に分離させることができる。本実施例のパレットＰの場合、パレット板１における第１、第３及び第５係止爪群Ｂ₁,Ｂ₃,Ｂ₅の直下の部分に、各桁材２が取付けられている。そして、各桁材２どうしの間には、フォークリフト爪Ｎを挿入させるための爪挿入空間Ｖが形成される。 As shown in FIGS. 6 to 8, the spar 2 and the pallet plate 1 which are bent and held in a rectangular tube shape and in which the respective support members 5 are arranged are integrally attached. That is, in a state where the girders 2 are arranged on the bottom surface portion of the pallet plate 1, the respective locking claws 3 provided on the pallet plate 1 are bent downward. Each locking claw 3 enters the locking hole opening 13 of the corresponding beam member 2. At this time, each locking claw 3 enters the locking hole 20 of the girder 2 with almost the same action as the locking claw 7 of the ceiling plate 6 in the girder 2. Width W ₁ of the locking claw 3 of the pallet plate 1 is larger than the width W ₅ of the locking hole 20, one end portion 3b of the locking claw 13 (right end in the drawing as viewed in FIG. 6), folded plate The edge portion 12a of the portion 12 is moved to the side (the first side plate portion 8 side), and the other end portion 3c is connected to the ceiling plate portion 6 of the beam 2 on the opposite side (of the second side plate portion 11). The locking hole 20 while moving to the side). And the connection part 3a of each latching claw 3 penetrates into the part (narrow width part 13a) where the cut width is narrow in each latching hole 20, or overlaps with the latching claw 7 of the girder 2 Thus, the folded plate portion 12 is returned. Thereby, each latching claw 3 is prevented from coming off, and the pallet plate 1 and the girder 2 are integrally attached. By folding each latching claw 3 of the pallet plate 1 in the opposite direction and returning it, the pallet plate 1 and the girder 2 can be easily separated. In the case of the pallet P of this embodiment, each girder 2 is attached to a portion of the pallet plate 1 immediately below the first, third and fifth locking claw groups B ₁ , B ₃ and B ₅ . A claw insertion space V for inserting the forklift claw N is formed between the girders 2.

次に、梱包箱Ｃ₁について説明する。図１及び図９に示されるように、梱包箱Ｃ₁は所定厚の段ボール板から成り、組立状態における内側は、パレット板１よりも少し広い。梱包箱Ｃ₁の側板部１４の下部で、収容状態でのパレットＰの各爪挿入空間Ｖに対応する部分には、フォークリフト爪Ｎを挿通させるための各爪孔１４ａが設けられている。被梱包物Ｄは、梱包箱Ｃ₁の底面部に収容されたパレットＰに設置されて収容される。各爪孔１４ａの高さ（内側寸法）は、パレットＰの桁材２の第１側板部８の幅Ｋ₂（図６参照）よりも少し高く、パレットＰの収容状態で、各爪孔１４ａの上縁部は、パレット板１の底面部よりも少し上方に配置される（図１０参照）。このため、フォークリフト爪Ｎが上昇したとき、最初にパレット板１の底面部に当接する。 Next, a description will be given of the packing box C _1. As shown in FIGS. 1 and 9, the packaging box C ₁ is made of a corrugated board having a predetermined thickness, and the inner side in the assembled state is slightly wider than the pallet board 1. At the bottom of the side plate portion 14 of the packing box C _1, the pallet portion corresponding to each pawl insertion space V of P in the housing state, the claws hole 14a for inserting the forklift claws N are provided. Object to be packed D is accommodated is placed on the pallet P accommodated in the bottom portion of the packing box C _1. The height (inside dimension) of each claw hole 14a is slightly higher than the width K ₂ (see FIG. 6) of the first side plate portion 8 of the beam 2 of the pallet P, and each claw hole 14a is in the accommodated state of the pallet P. The upper edge portion is disposed slightly above the bottom surface portion of the pallet plate 1 (see FIG. 10). For this reason, when the forklift claw N rises, it first contacts the bottom surface of the pallet plate 1.

図９及び図１０を参照しながら、第１実施例の段ボール製梱包箱装置Ａ₁の作用について説明する。被梱包物Ｄに対して最適な大きさのパレット板１と各桁材２が選択される。本実施例の場合、パレット板１における各桁材２の取付間隔Ｌ₂が、被梱包物Ｄの幅Ｒに近いものが選択される。梱包箱Ｃ₁の各側板部１４が折り曲げられ、下面が閉塞状態に形成される。図８に示されるように、角筒状に折り曲げられ、内部に各支持部材５が配置された桁材２が、パレット板１における第１、第３及び第５の各係止爪群Ｂ₁,Ｂ₃,Ｂ₅の直下に配置され、パレット板１の各係止爪３が下方に折り曲げられて対応する桁材２の係止孔２０に入り込んで係止される。これにより、パレットＰが形成される。本実施例の場合、パレット板１と各桁材２とを一体に取付けるときに糊等の接着剤を使用する必要がないため容易であり、しかも、梱包現場を汚損するおそれはない。 The operation of the cardboard packaging box device A _{1 according to} the first embodiment will be described with reference to FIGS. The pallet plate 1 and the girders 2 having the optimum size for the package D are selected. In the case of the present embodiment, the attachment interval L ₂ of the beam members 2 on the pallet plate 1 is selected to be close to the width R of the article D to be packed. Each side plate portion 14 of the packaging box C ₁ is bent, the lower surface is formed in the closed state. As shown in FIG. 8, the girder member 2 that is bent into a rectangular tube shape and in which the respective support members 5 are arranged is the first, third, and fifth locking claw groups B ₁ in the pallet plate 1. , B ₃ , B ₅ , each locking claw 3 of the pallet plate 1 is bent downward and enters the locking hole 20 of the corresponding beam member 2 to be locked. Thereby, the pallet P is formed. In the case of the present embodiment, there is no need to use an adhesive such as glue when the pallet plate 1 and each girder 2 are attached together, and there is no risk of fouling the packing site.

続いて、梱包箱Ｃ₁の底部にパレットＰが収容される。この状態で、図１０の（イ）に示されるように、パレットＰの各爪挿入空間Ｖは、一対の側板部１４の下部に設けられた各爪孔１４ａと対応して配置され、各爪孔１４ａを介してフォークリフト爪Ｎを、前記爪挿入空間Ｖに挿入させることができる。そして、パレット板１に被梱包物Ｄが設置される。最下段の被梱包物Ｄ（パレット板１に直接設置される被梱包物Ｄ）における４つの底辺のうち、パレット板１の奥行方向に沿って配置される側の２辺（稜線１５）が、各桁材２の直上の部分に配置される。これにより、被梱包物Ｄが重量物であっても確実に支持される。 Then, the pallet P is accommodated in the bottom of the packing case C _1. In this state, as shown in FIG. 10 (A), each claw insertion space V of the pallet P is arranged corresponding to each claw hole 14a provided in the lower part of the pair of side plate portions 14, and each claw The forklift claw N can be inserted into the claw insertion space V through the hole 14a. Then, an article D to be packed is installed on the pallet plate 1. Of the four bases in the bottom packaged item D (packaged product D directly installed on the pallet plate 1), two sides (ridge line 15) on the side arranged along the depth direction of the pallet plate 1 are: It arrange | positions in the part immediately above each girder 2. Thereby, even if the to-be-packaged goods D is a heavy article, it is supported reliably.

次に、梱包現場において、収容される被梱包物Ｄが被梱包物Ｄ’に変更された場合について説明する。ここで、被梱包物Ｄ’の幅Ｒ’は、被梱包物Ｄの幅Ｒよりも狭い。該パレットＰに被梱包物Ｄ’をそのまま設置させると、被梱包物Ｄ’における稜線１６が、パレット板１の中央部の桁材２に掛からなくなってしまい、被梱包物Ｄ’を的確に支持できなくなるおそれがある。この場合、図１０の（ロ）に示されるように、パレット板１における幅方向の中央部の桁材２（第３係止爪群Ｂ₃に対応する桁材２）を取り外し、第２及び第４の係止爪群Ｂ₂,Ｂ₄の部分に各桁材２を取付ける。被梱包物Ｄ’の幅Ｒ’が、新たにパレット板１に取付けられた各桁材２の取付間隔Ｌ₃に近ければ、被梱包物Ｄ’における底面部の稜線１６は、各桁材２の直上に配置される。これにより、被梱包物Ｄ’を確実に支持することができる。しかも、各桁材２の取付位置を変更した場合であっても、爪挿入空間Ｖはそのまま確保され、フォークリフト爪Ｎを挿入させるのに支障はない。 Next, the case where the packaged article D to be accommodated is changed to the packaged article D ′ at the packing site will be described. Here, the width R ′ of the packaged object D ′ is narrower than the width R of the packaged object D. If the article to be packed D ′ is installed on the pallet P as it is, the ridge line 16 in the article to be packed D ′ will not be hooked on the beam 2 in the center of the pallet plate 1 and the article to be packed D ′ is accurately supported. There is a risk that it will not be possible. In this case, as shown in (b) of FIG. 10, the spar 2 in the center in the width direction of the pallet plate 1 (the spar 2 corresponding to the third locking claw group B ₃ ) is removed, Each girder 2 is attached to the portion of the fourth locking claw group B ₂ , B ₄ . If the width R ′ of the article to be packed D ′ is close to the attachment interval L ₃ between the girders 2 newly attached to the pallet plate 1, the ridge line 16 at the bottom of the article to be packaged D ′ It is placed immediately above. Thereby, the to-be-packaged object D ′ can be reliably supported. And even if it is a case where the attachment position of each girder 2 is changed, claw insertion space V is secured as it is, and there is no trouble in inserting forklift claw N.

本実施例の段ボール製梱包箱装置Ａ₁の場合、パレットＰを構成するパレット板１と桁材２とを分離させた状態で保管することができるため、それらを保管するためのスペースが小さくて済む。また、パレット板１及び桁材２の運搬も容易である。 In the case of the corrugated cardboard packaging box device A ₁ of the present embodiment, the pallet plate 1 and the girder 2 constituting the pallet P can be stored in a separated state, so that the space for storing them is small. That's it. Moreover, the pallet board 1 and the girder 2 can be easily transported.

次に、第２実施例の段ボール製梱包箱装置Ａ₂について説明する。図１１は第２実施例の段ボール製梱包箱装置Ａ₂の斜視図、図１２は同じく分解斜視図、図１３は連結部材Ｓの斜視図である。図１１及び図１２に示されるように、段ボール製梱包箱装置Ａ₂は、上箱１７と下箱１８とから成る梱包箱Ｃ₂と、パレットＰと、重なり状態の上箱１７と下箱１８とが分離することを防止するための連結部材Ｓとから構成されている。前記パレットＰは、第１実施例の段ボール製梱包箱装置Ａ₁におけるパレットＰと同一である。 Next, the corrugated cardboard packaging box device A ₂ of the second embodiment will be described. FIG. 11 is a perspective view of the cardboard packaging box device A ₂ of the _second embodiment, FIG. 12 is an exploded perspective view, and FIG. 13 is a perspective view of the connecting member S. As shown in FIGS. 11 and 12, the cardboard packaging box device A ₂ includes a packaging box C ₂ composed of an upper box 17 and a lower box 18, a pallet P, and an upper box 17 and a lower box 18 in an overlapped state. And a connecting member S for preventing separation. The pallet P is the same as the pallet P in the cardboard packaging box device A ₁ of the first embodiment.

梱包箱Ｃ₂について説明する。図１１及び図１２に示されるように、梱包箱Ｃ₂を構成する上箱１７は、所定厚ｔ₂の段ボール板より成り、組立て状態（折曲げ状態）で下面が開口していると共に、上面は、折り曲げられた天井板部１９によって閉塞されている。また、上箱１７の各側板部２１の下部で、下箱１８に収容されたパレットＰの各爪挿入空間Ｖに対応する部分は高さ方向に切り込まれていて、各折返し片２２が形成されている。同じく下箱１８は、所定厚ｔ₃の段ボール板より成り、組立て状態（折曲げ状態）で上面が開口していると共に、下面は底板部２３によって閉塞されている。下箱１８の各側板部２４の外周縁の大きさは、上箱１７の各側板部２１の内周縁の大きさよりも僅かに小さい。このため、下箱１８に上箱１７を覆い被せることができる。また、下箱１８の各側板部２４のうち、該下箱１８に収容されたパレットＰの各爪挿入空間Ｖに対応する部分には、フォークリフト爪Ｎを挿入させるための各爪孔２５が形成されている。各爪孔２５の高さＨ₁は、桁材２の高さＫ₂よりも少し高い（図１５参照）。本実施例の場合、各爪孔２５の内幅は、上箱１７の折返し片２２の切込み幅とほぼ等しい。このため、下箱１８に上箱１７が覆い被せられたとき、上箱１７の折返し片２２の抜き孔２２ａと下箱１８の爪孔２５は、幅方向においてほぼ合致する。この状態で、上箱１７の折返し片２２が内側に折り返される。該折返し片２２は、パレットＰの爪挿入空間Ｖに入り込み、パレット板１の直下に配置される（図１１参照）。そして、上下の各箱１７，１８を分離不能に連結するために、前記折返し片２２の抜き孔２２ａから連結部材Ｓが挿入される。なお、図１２において、２６はテープである。 For packing box C ₂ will be described. As shown in FIGS. 11 and 12, the upper box 17 constituting the packing box C ₂ is made of a corrugated board having a predetermined thickness t ₂ , and the lower surface is opened in the assembled state (bending state), and the upper surface Is closed by the bent ceiling plate portion 19. Moreover, the part corresponding to each nail | claw insertion space V of the pallet P accommodated in the lower box 18 in the lower part of each side plate part 21 of the upper box 17 is cut | disconnected in the height direction, and each folding piece 22 forms. Has been. Similarly, the lower box 18 is made of a corrugated board having a predetermined thickness t ₃ , and its upper surface is opened in an assembled state (bending state), and its lower surface is closed by a bottom plate portion 23. The size of the outer peripheral edge of each side plate portion 24 of the lower box 18 is slightly smaller than the size of the inner peripheral edge of each side plate portion 21 of the upper box 17. For this reason, the upper box 17 can be covered with the lower box 18. In addition, each claw hole 25 for inserting the forklift claw N is formed in a portion of each side plate portion 24 of the lower box 18 corresponding to each claw insertion space V of the pallet P accommodated in the lower box 18. Has been. The height H ₁ of each claw hole 25 is slightly higher than the height K ₂ of the girder 2 (see FIG. 15). In the case of the present embodiment, the inner width of each claw hole 25 is substantially equal to the cut width of the folded piece 22 of the upper box 17. For this reason, when the upper box 17 is covered with the lower box 18, the punching hole 22 a of the folded piece 22 of the upper box 17 and the claw hole 25 of the lower box 18 substantially coincide with each other in the width direction. In this state, the folded piece 22 of the upper box 17 is folded inward. The folded piece 22 enters the claw insertion space V of the pallet P and is disposed immediately below the pallet plate 1 (see FIG. 11). And in order to connect the upper and lower boxes 17 and 18 inseparably, the connecting member S is inserted from the punched hole 22a of the folded piece 22. In FIG. 12, reference numeral 26 denotes a tape.

次に、連結部材Ｓについて説明する。図１４に示されるように、連結部材Ｓは、所定厚の段ボール板を逆Ｕ字状に折り曲げたものであり、折曲げ状態における上板部２７の全幅Ｗ₆は、上箱１７の折返し片２２の抜き孔２２ａの内幅Ｗ₇よりも少し短い。前記上板部２７の両側に、一対の側板部２８が垂下されて形成されている。前記上板部２７の前部には、平面視においてＬ字状の切込みが、２箇所に対称形状で設けられている。このため、上板部２７の両端部を下方に折り曲げて一対の側板部２８を形成したとき、各側板部２８の上部は、切込みの分だけ上板部２７から突出し、高さＨ₂の各抜止め部２９が形成される。また、各側板部２８の後端部の下部には、ストッパ部３１が突設されている。図１５に示されるように、前記抜止め部２９の高さＨ₂は、上箱１７の板厚ｔ₂よりも少し短い。また、前記ストッパ部３１における側板部２８の下端縁からの突出長Ｈ₃は、下箱１８の板厚ｔ₃よりも少し短い。 Next, the connecting member S will be described. As shown in FIG. 14, the connecting member S is obtained by folding a corrugated cardboard plate having a predetermined thickness into an inverted U shape, and the total width W ₆ of the upper plate portion 27 in the folded state is the folded piece of the upper box 17. 22 is slightly shorter than the inner width W ₇ of the punched hole 22a. On both sides of the upper plate portion 27, a pair of side plate portions 28 are formed to hang down. In the front portion of the upper plate portion 27, L-shaped cuts are provided in two locations symmetrically in plan view. For this reason, when both ends of the upper plate portion 27 are bent downward to form a pair of side plate portions 28, the upper portions of the side plate portions 28 protrude from the upper plate portion 27 by the amount of the cut, and each of the heights H ₂ A retaining portion 29 is formed. Further, a stopper portion 31 protrudes from a lower portion of the rear end portion of each side plate portion 28. As shown in FIG. 15, the height H ₂ of the retaining portion 29 is slightly shorter than the plate thickness t ₂ of the upper box 17. Further, the protruding length H ₃ from the lower edge of the side plate portion 28 in the stopper portion 31 is slightly shorter than the plate thickness t ₃ of the lower box 18.

前記連結部材Ｓは、図１４ないし図１６に示されるように、下箱１８に覆い被されて折返し片２２が内側に折り返された上箱１７の外側から、折返し片２２の抜き孔２２ａを介して、下箱１８の爪孔２５の部分に挿入される。爪孔２５の内幅は、前記抜き孔２２ａの内幅Ｗ₇とほぼ同一であり、しかも、折返し片２２の抜き孔２２ａの高さＨ₄(図１６参照）よりも高いため、連結部材Ｓは、図１４に二点鎖線で示されるように、一対の側板部２８が内側に屈曲され、全高を低くさせた状態で挿入される。そして、連結部材Ｓにおける抜止め部２９の部分が、上箱１７の折返し片２２の前端部２２ｂを超えると、一対の側板部２８の屈曲状態が解除されて、上板部２７とほぼ直角の状態を呈する。これにより、一対の抜止め部２９もほぼ起立状態となり、その後端部２９ａが、前記折返し片２２の前端部２２ｂと近接して対向配置される。また、この状態で、連結部材Ｓのストッパ部３１の前端部３１ａも、下箱１８の底板部２３の端面部２３ａと近接して対向配置される。この結果、連結部材Ｓの抜止めが図られると共に、前記連結部材Ｓにより、上箱１７の折返し片２２が下箱１８の爪孔２５を介してパレットＰの爪挿入空間Ｖに入り込んでいる状態が保持され、上箱１７と下箱１８とは分離不能となる。更に、連結部材Ｓが挿入された状態においても、上板部２７と一対の側板部２８との間には、フォークリフト爪Ｎを挿入可能な空間部が、パレットＰの爪挿入空間Ｖに連続して形成されるため、この状態においてもフォークリフト爪Ｎによって段ボール製梱包箱装置Ａ₂を持ち上げることができる。連結部材Ｓを取り外すときは、挿入するときと同様に、一対の側板部２８を内側に屈曲させながら引き出す。これにより、上箱１７と下箱１８とを容易に分離させることができる。 As shown in FIGS. 14 to 16, the connecting member S is covered from the outer side of the upper box 17 that is covered with the lower box 18 and the folded piece 22 is folded back to the inside through the hole 22 a of the folded piece 22. Then, it is inserted into the claw hole 25 portion of the lower box 18. Since the inner width of the claw hole 25 is substantially the same as the inner width W _{7 of the} punch hole 22a and is higher than the height H ₄ (see FIG. 16) of the punch hole 22a of the folded piece 22, the connecting member S As shown by a two-dot chain line in FIG. 14, the pair of side plate portions 28 are bent inward and are inserted in a state where the overall height is lowered. Then, when the portion of the retaining portion 29 in the connecting member S exceeds the front end portion 22b of the folded piece 22 of the upper box 17, the bent state of the pair of side plate portions 28 is released and is substantially perpendicular to the upper plate portion 27. Presents a state. As a result, the pair of retaining portions 29 is also substantially upright, and the rear end portion 29 a is disposed in close proximity to the front end portion 22 b of the folded piece 22. In this state, the front end portion 31 a of the stopper portion 31 of the connecting member S is also disposed close to and opposed to the end surface portion 23 a of the bottom plate portion 23 of the lower box 18. As a result, the connecting member S is prevented from being removed, and the connecting member S allows the folded piece 22 of the upper box 17 to enter the claw insertion space V of the pallet P through the claw hole 25 of the lower box 18. Is held, and the upper box 17 and the lower box 18 cannot be separated. Further, even when the connecting member S is inserted, a space portion in which the forklift claw N can be inserted is continuous between the claw insertion space V of the pallet P between the upper plate portion 27 and the pair of side plate portions 28. Therefore, even in this state, the cardboard packaging box device A ₂ can be lifted by the forklift claws N. When removing the connecting member S, the pair of side plate portions 28 are pulled out while being bent inward as in the case of insertion. Thereby, the upper box 17 and the lower box 18 can be easily separated.

第２実施例の段ボール製梱包箱装置Ａ₂の作用について説明する。図１２及び図１５に示されるように、下箱１８に収容されたパレットＰに被梱包物Ｄが設置される。パレットＰの周囲が開放されているため、被梱包物Ｄを設置する作業が容易である。また、梱包を解除して、被梱包物Ｄを取り出す作業も容易である。パレットＰに被梱包物Ｄが設置された後、上箱１７が覆い被せられ、各折返し片２２が内側に折り曲げられる。各折返し片２２は、下箱１８の爪孔２５を介してパレットＰの爪挿入空間Ｖに配置される。 The operation of the corrugated cardboard packaging box apparatus A ₂ of the second embodiment will be described. As shown in FIGS. 12 and 15, an article D to be packed is placed on the pallet P accommodated in the lower box 18. Since the periphery of the pallet P is open, the work of installing the article to be packed D is easy. Moreover, the operation | work which cancels | releases packing and takes out the to-be-packaged goods D is also easy. After the article to be packed D is installed on the pallet P, the upper box 17 is covered and each folded piece 22 is bent inward. Each folded piece 22 is arranged in the claw insertion space V of the pallet P through the claw hole 25 of the lower box 18.

続いて、上箱１７の折返し片２２の抜き孔２２ａの部分に、連結部材Ｓの一対の側板部２８を、幅方向に屈曲させながら挿入させる。連結部材Ｓの抜止め部２９が、折返し片２２の前端部２２ｂを超えると屈曲状態が解放され、折返し片２２と抜止め部２９とが係止される。これにより、連結部材Ｓの抜止めが図られる。また、ストッパ部３１が、下箱１８の底板部２３の端面部２３ａに当接するため、前記連結部材Ｓがそれ以上挿入されることが防止される。これにより、上箱１７と下箱１８は、連結部材Ｓによって分離不能に連結される。この結果、搬送途中において、上箱１７と下箱１８が分離され、不正に梱包解除されることを阻止できる。そして、前記連結部材Ｓを介してパレットＰの爪挿入空間Ｖにフォークリフト爪Ｎを挿入して持ち上げる。連結部材Ｓの上板部２７が持ち上げられると、上箱１７の折返し片２２を介してパレット板１の底面部に当接し、被梱包物Ｄが設置されたパレットＰ全体が持ち上げられる。折返し片２２が持ち上げられると、下箱１８の爪孔２５に当接し、下箱１８が持ち上げられる。この結果、段ボール製梱包箱装置Ａ₂の全体が持ち上げられる。パレット板１と折返し片２２との間、及び折返し片２２と連結部材Ｓの上板部２７との間には隙間が殆どないので、前記連結部材Ｓにフォークリフト爪Ｎを挿入して被梱包物Ｄの搬送作業を行っても、折返し片２２の前端部２２ｂと連結部材Ｓの抜止め部２９の後端部２９ａとの係止状態が維持される。 Subsequently, the pair of side plate portions 28 of the connecting member S are inserted into the portion of the hole 22a of the folded piece 22 of the upper box 17 while being bent in the width direction. When the retaining portion 29 of the connecting member S exceeds the front end portion 22b of the folded piece 22, the bent state is released and the folded piece 22 and the retaining portion 29 are locked. As a result, the connecting member S is prevented from being pulled out. Moreover, since the stopper part 31 contacts the end surface part 23a of the bottom plate part 23 of the lower box 18, it is prevented that the connecting member S is further inserted. Thereby, the upper box 17 and the lower box 18 are connected by the connecting member S so as not to be separated. As a result, it is possible to prevent the upper box 17 and the lower box 18 from being separated and being unpacked illegally during the conveyance. Then, the forklift claw N is inserted into the claw insertion space V of the pallet P through the connecting member S and lifted. When the upper plate portion 27 of the connecting member S is lifted, the entire pallet P on which the articles to be packaged D are lifted is brought into contact with the bottom surface portion of the pallet plate 1 via the folded piece 22 of the upper box 17. When the folded piece 22 is lifted, it comes into contact with the claw hole 25 of the lower box 18 and the lower box 18 is lifted. As a result, the entire cardboard packaging box device A ₂ is lifted. Since there is almost no gap between the pallet plate 1 and the folded piece 22 and between the folded piece 22 and the upper plate portion 27 of the connecting member S, the forklift claw N is inserted into the connecting member S to be packed. Even when the transfer operation D is performed, the locked state between the front end portion 22b of the folded piece 22 and the rear end portion 29a of the retaining portion 29 of the connecting member S is maintained.

第２実施例の段ボール製梱包箱装置Ａ₂では、上箱１７と下箱１８の下端部に、折返し片２２と爪孔２５が設けられていて、連結部材Ｓを、梱包箱Ｃ₂の下端部に挿入させる形態である。このため、下箱１８の高さを低くすることができ、被梱包物Ｄの設置が容易である。また、連結部材Ｓを取り外す場合には、段ボール製梱包箱装置Ａ₂において前記連結部材Ｓが挿入された側板部２１の周囲に、所定の大きさの空間部を必要とする。換言すれば、被梱包物Ｄを梱包した段ボール製梱包箱装置Ａ₂どうしを近接配置させることにより、前記空間部が形成されなくなり、不正に梱包解除されることを一層確実に阻止できる。なお、第２実施例の段ボール製梱包箱装置Ａ₂を構成するパレットＰは、段ボール以外のもの（例えば、木材、樹脂材等）から成るものであっても構わない。 In the cardboard packaging box device A _{2 of} the second embodiment, the folded pieces 22 and the claw holes 25 are provided at the lower ends of the upper box 17 and the lower box 18, and the connecting member S is connected to the lower end of the packing box C ₂ . This is a form to be inserted into the part. For this reason, the height of the lower box 18 can be made low and the installation of the packaged goods D is easy. Further, when detaching the coupling member S is around the coupling member S is inserted the side plate portion 21 in the cardboard packing box device A _2, it requires a space of a predetermined size. In other words, by arranging the cardboard packaging box devices A ₂ packed with the articles to be packed D close to each other, the space portion is not formed, and it is possible to more reliably prevent the package from being illegally released. The pallet P constituting the corrugated cardboard packaging box device A ₂ of the second embodiment may be made of a material other than corrugated cardboard (for example, wood, resin material, etc.).
