Description

この発明は、複写機、プリンタ、ファクシミリなどの製品を梱包するときに使用する包装箱に関する。詳しくは、各２つを互いに対向して設ける４つの矩形状の側面と、それら側面の上下辺にそれぞれ折り曲げ自在に連結して設けるフラップとを有する、段ボール箱等の包装箱に関する。 The present invention relates to a packaging box used when packaging products such as copiers, printers, and facsimiles. Specifically, the present invention relates to a packaging box such as a cardboard box, which has four rectangular side surfaces that are provided so as to face each other and flaps that are connected to the upper and lower sides of the side surfaces so as to be bent.

従来、複写機等の製品を梱包するときに使用する包装箱は、例えば図１１に示す平面図から判るとおり、包装箱１内の四隅に緩衝材２を入れて後、それらの緩衝材２上に載置して包装箱１内に製品３を収納していた。そして、開梱時は、図示省略する上フラップを開いて上から包装箱１と製品３との間の隙間Ｂに手ｈを入れ、その手ｈを例えばａ位置で製品３の底部に掛けて製品３を持ち上げ、包装箱１内から取り出していた。 Conventionally, a packaging box used when packing a product such as a copying machine has a cushioning material 2 placed in four corners of the packaging box 1 and then on the cushioning material 2 as can be seen from the plan view shown in FIG. The product 3 was stored in the packaging box 1. At the time of unpacking, the upper flap (not shown) is opened, and a hand h is inserted into the gap B between the packaging box 1 and the product 3 from above, and the hand h is hung on the bottom of the product 3 at the position a, for example. The product 3 was lifted and taken out from the packaging box 1.

このため、包装箱１と製品３との間の隙間Ｂは、その隙間Ｂに手ｈが入るように手の幅Ｃよりも大きくする必要があり、その結果包装箱１の幅Ｄが大きくなって包装箱１が大型化する問題があった。 For this reason, the gap B between the packaging box 1 and the product 3 needs to be larger than the width C of the hand so that the hand h enters the gap B. As a result, the width D of the packaging box 1 is increased. There is a problem that the packaging box 1 is enlarged.

そこで、従来の包装箱の中には、例えば図１２に示すように、４つの側面の少なくとも１つの側面４の下辺にカットテープ５を貼り付けるとともに、その側面４の片縁をジョイント部材６で隣接側面７の止め代用フラップ７ａに連結するものがある。そして、開梱時は、カットテープ５を引っ張って側面４の下辺で切断し、ジョイント部材６を外して片縁を止め代用フラップ７ａから分離して他縁を中心として側面４を図中矢示方向に開き、包装箱１内から不図示の製品を取り出していた。 Therefore, in the conventional packaging box, for example, as shown in FIG. 12, the cut tape 5 is attached to the lower side of at least one side surface 4 of the four side surfaces, and one edge of the side surface 4 is joined by the joint member 6. Some are connected to a stop substitute flap 7a on the adjacent side surface 7. At the time of unpacking, the cut tape 5 is pulled and cut at the lower side of the side surface 4, the joint member 6 is removed, one edge is separated from the stop substitute flap 7a, and the side surface 4 is oriented in the direction indicated by the arrow in the figure. The product (not shown) was taken out from the packaging box 1.

また、従来の包装箱の中には、例えば図１３に示すように、１つの側面４の両側縁付近にそれぞれ縦方向のミシン目８を有するものがある。そして、開梱時は、上フラップ９を持ってそれらのミシン目８で切断して下縁を中心として上フラップ９とともに側面４を下向きに開き、包装箱１内から製品３を取り出していた。 Further, some conventional packaging boxes have longitudinal perforations 8 in the vicinity of both side edges of one side surface 4 as shown in FIG. At the time of unpacking, the upper flap 9 is held and cut at the perforations 8 to open the side face 4 downward together with the upper flap 9 around the lower edge, and the product 3 is taken out from the packaging box 1.

このようにすると、包装箱１の側面４側が開くから包装箱１と製品３との隙間を大きくすることなく、製品３の取り出しを容易とすることができる。よって、包装箱１を小型化することができる。 In this way, since the side surface 4 side of the packaging box 1 is opened, the product 3 can be easily taken out without increasing the gap between the packaging box 1 and the product 3. Therefore, the packaging box 1 can be reduced in size.

Further, the folding pieces 14 and 15 are prevented from being opened by the elastic force of the cardboard and obstructing the assembly of the packaging box, and the assembling workability when the packaging box is assembled is improved.

次いで、図４に示すように、長手側面１２・１３の側縁と短手側面２６の左右両側縁とをそれぞれ突き合わせて外側から貼り付けて接着テープ３３で止めて固定する。 Next, as shown in FIG. 4, the side edges of the long side surfaces 12 and 13 and the left and right side edges of the short side surface 26 are brought into contact with each other and attached from the outside, and fixed with an adhesive tape 33.

その後、横折り曲げ線ｉ、ｏでそれぞれ下内フラップ２１・３１を折り曲げてから、横折り曲げ線ｋ、ｍで下外フラップ２３・２５を折り曲げ、それらの２つの下外フラップ２３・２５の先端縁間を不図示の接着テープで止めて図５に示す状態とする。これにより、互いに対向して設ける２つの長手側面１２・１３と２つの短手側面１０・２６とで４つの矩形状の側面を形成する。 Thereafter, the lower inner flaps 21 and 31 are bent at the horizontal folding lines i and o, respectively, and then the lower outer flaps 23 and 25 are bent at the horizontal folding lines k and m, and the leading edges of these two lower outer flaps 23 and 25 The gap is stopped with an adhesive tape (not shown) to obtain the state shown in FIG. Accordingly, four rectangular side surfaces are formed by the two long side surfaces 12 and 13 and the two short side surfaces 10 and 26 provided to face each other.

次いで、製品を梱包するときは、包装箱内の四隅に、図６に示すように４つの緩衝材３５を入れてから、それら緩衝材３５の上に載せて製品３６を入れる。４つの緩衝材３５のうちの２つ角部には、折り畳み片１４・１５を逃げる切欠き３７が設けられている。そして、横折り曲げ線ｈ、ｎでそれぞれ上内フラップ２０・３０を折り曲げてから、横折り曲げ線ｊ、ｌで上外フラップ２２・２４を折り曲げ、それらの２つの上外フラップ２２・２４の先端縁間を不図示の接着テープで止める。 Next, when packing the product, the four cushioning materials 35 are put in the four corners of the packaging box as shown in FIG. 6, and then the product 36 is put on the cushioning material 35. Cutouts 37 for escaping the folding pieces 14 and 15 are provided at two corners of the four cushioning members 35. Then, the upper inner flaps 20 and 30 are bent at the horizontal folding lines h and n, respectively, and then the upper and outer flaps 22 and 24 are bent at the horizontal folding lines j and l. The gap is stopped with an adhesive tape (not shown).

そして、図示包装箱では、製品３６と、２つの長手側面１２・１３との間の隙間Ｅおよび２つの短手側面１０・２６との間の隙間Ｆを、それらの隙間Ｅ、Ｆに手が入らないほど小さくし、幅Ｇおよび奥行きＨを小さくして全体を小型化し、荷扱いを簡単とする。また、長手側面１２・１３の側縁と短手側面２６の左右両側縁とをそれぞれ突き合わせて外側から貼り付けて接着テープ３３で固定するので、箱強度を低下したり、さほどコスト高となったりすることなく、製品３６を包装することができる。 In the illustrated packaging box, the gap E between the product 36 and the two long side faces 12 and 13 and the gap F between the two short side faces 10 and 26 are set in the gaps E and F. The size is reduced so as not to enter, the width G and the depth H are reduced, the whole is downsized, and handling is simplified. Further, since the side edges of the long side surfaces 12 and 13 and the left and right side edges of the short side surface 26 are brought into contact with each other and attached from the outside and fixed with the adhesive tape 33, the box strength is lowered or the cost is increased. The product 36 can be packaged without doing so.

さて、上述した包装箱の開梱時は、カッターナイフなどで接着テープ３３を切り開いたり接着テープを剥がしたりして、移動側面である短手側面２６の左右両側縁と、その短手側面２６に隣接する隣接側面である長手側面１２・１３の側縁とを離し、図７に示すように手掛け孔２７に手を掛けて短手側面２６を引っ張り、その引出力で係止片１６の被係止部１７への掛け止めを外す。そして、折り畳んである折り畳み片１４・１５を開いて伸張し、長手側面１２・１３から離すことにより短手側面２６を上下内フラップ３０・３１とともに水平方向に移動して短手側面２６を開く。これにより、製品３６と短手側面２６との間の隙間をＦからＩに拡げ、余裕を持って手が入るスペースを確保する。 Now, when unpacking the packaging box described above, the adhesive tape 33 is cut or peeled off with a cutter knife or the like, and the right and left side edges of the short side face 26 that is the moving side face and the short side face 26 are removed. The side edges of the long side surfaces 12 and 13, which are adjacent side surfaces, are separated from each other, and the short side surface 26 is pulled by placing the hand on the handle hole 27 as shown in FIG. Remove the latch on the stopper 17. Then, the folded folding pieces 14 and 15 are opened and extended, and the short side face 26 is moved together with the upper and lower inner flaps 30 and 31 in the horizontal direction by moving away from the long side faces 12 and 13, thereby opening the short side face 26. Thereby, the clearance gap between the product 36 and the short side surface 26 is expanded from F to I, and the space which a hand enters with a margin is ensured.

開梱時に、手掛け孔２７に手を掛けて短手側面２６を引っ張り、折り畳み片１４・１５を伸張することにより水平方向に移動して短手側面２６を開くので、包装箱を開梱するときの包装箱の開梱作業性を向上することができる。 When unpacking the packaging box, the user pulls the short side surface 26 by pulling the hand hole 27 and unfolds the folding pieces 14 and 15 to move horizontally to open the short side surface 26. The unpacking workability of the packaging box can be improved.

それから、収納する製品３６を押して同方向に移動して、図８に示すように製品３６と短手側面２６との間の隙間をＩからＪに狭めるが、製品３６と短手側面１０との間の隙間をＦからＪにほぼ等しいＫに拡げ、対向する２つの短手側面１０・２６と製品３６との間の隙間をＦから手３８の幅Ｃより広いＪ、Ｋまで大きくする。 Then, the product 36 to be stored is pushed and moved in the same direction, and the gap between the product 36 and the short side surface 26 is narrowed from I to J as shown in FIG. The gap between the two short side surfaces 10 and 26 and the product 36 facing each other is increased from F to J and K wider than the width C of the hand 38.

そして、図８に示すように、それらの隙間Ｊ、Ｋに手３８を入れて製品３６の手掛け部３９・３９に手を掛けて製品３６を持ち上げて取り出す。 Then, as shown in FIG. 8, the hand 38 is put into the gaps J and K, the hands 36 are placed on the handle portions 39 and 39, and the product 36 is lifted and taken out.

ところで、上述した例では、互いに対向して設ける２つの長手側面１２・１３と２つの短手側面１０・２６とで形成する４つの矩形状の側面のうち１つの側面２６を移動側面とした。しかし、例えば図９に示すように、互いに対向する２つの短手側面１０・２６の双方を移動側面としてもよい。そして、開梱時は、２つの短手側面１０・２６をともに水平方向に移動し、それらの短手側面１０・２６と製品３６との間の隙間を各々大きくし、その隙間に手を入れて製品３６を持ち上げて取り出す。 By the way, in the above-described example, one side surface 26 of the four rectangular side surfaces formed by the two long side surfaces 12 and 13 and the two short side surfaces 10 and 26 provided to face each other is used as the moving side surface. However, as shown in FIG. 9, for example, both of the two short side surfaces 10 and 26 facing each other may be used as the moving side surfaces. When unpacking, move the two short side faces 10 and 26 in the horizontal direction to increase the gaps between the short side faces 10 and 26 and the product 36. Lift the product 36 and take it out.

このようにすると、収納する製品３６を水平方向に移動する必要なく、製品３６の両側で、短手側面１０・２６と製品３６との間の隙間に手を入れて製品３６をそのまま持ち上げて取り出すことができ、包装箱を開梱して製品３６を取り出すときの製品３６の取り出し作業性を向上することができる。 In this way, it is not necessary to move the product 36 to be stored in the horizontal direction, and on both sides of the product 36, the product 36 is lifted and taken out as it is by putting a hand in the gap between the short side surfaces 10, 26 and the product 36. It is possible to improve the workability of taking out the product 36 when the packaging box is opened and the product 36 is taken out.

また、上述した例では、短手側面２６を移動側面とし、その左右両側縁を伸張自在な折り畳み片１４・１５を介して各々隣接側面である長手側面１２・１３に連結し、開梱時には、折り畳み片１４・１５を伸張して短手側面２６を水平方向に移動し、製品３６との間の隙間を大きくし、その隙間に手を入れて製品３６の手掛け部３９・３９に手を掛け、製品３６を持ち上げて取り出すようにした。 Further, in the above-described example, the short side surface 26 is the moving side surface, and the left and right side edges thereof are connected to the long side surfaces 12 and 13 which are adjacent side surfaces via the extendable folding pieces 14 and 15, respectively, The folding pieces 14 and 15 are extended to move the short side surface 26 in the horizontal direction, the gap between the product 36 is increased, and a hand is put in the gap 36 to hang the hand portions 39 and 39 of the product 36. The product 36 is lifted and taken out.

しかし、図１０に示すように、製品３６の長手側に手掛け部４０があるときには、長手側面１２を移動側面とし、その左右両側縁を伸張自在な折り畳み片１４・１５を介して各々隣接側面である短手側面１０・２６に連結し、開梱時には、その長手側面１２を水平方向に移動して製品３６との間の隙間を大きくし、その隙間に手を入れて製品３６の手掛け部４０に手を掛け、製品３６を持ち上げて取り出すようにしてもよい。もちろん、対向する２つの長手側面１２・１３をともに移動側面としてもよい。 However, as shown in FIG. 10, when the handle portion 40 is on the longitudinal side of the product 36, the longitudinal side surface 12 is used as a moving side surface, and the left and right side edges thereof are respectively connected to adjacent side surfaces via the folding pieces 14 and 15. At the time of unpacking, the long side surface 12 is moved in the horizontal direction to widen the gap between the product 36 and the hand 36 is inserted into the gap. The product 36 may be lifted and taken out. Of course, the two opposing longitudinal side surfaces 12 and 13 may be used as moving side surfaces.
