従来、電子機器や精密機器類、貴ガラス・陶器類など、衝撃に敏感な包装物の輸送に耐えるための梱包方法として、図１２に示すように空気袋や発泡体などの衝撃緩衝材１を包装物２と包装容器３との空隙４に詰めることによって、輸送中における包装物２の損傷を防止するようにした空隙充填方法や、図１３に示すような発泡体をもって包装物２の外形に合わせた緩衝性保持材５を使用して包装物２を保持するもの、包装容器に緩衝材のあるシート２枚を上下に張設し、そのシート間に包装物を挟んだ状態に保持させることにより、包装物を宙吊り状態にするハンモック方式が一般的であった。   Conventionally, as a packing method for withstanding the transportation of impact sensitive packages such as electronic equipment, precision equipment, precious glass, ceramics, etc., an impact cushioning material 1 such as an air bag or foam as shown in FIG. By filling the gap 4 between the package 2 and the packaging container 3 to prevent the package 2 from being damaged during transportation, the outer shape of the package 2 with a foam as shown in FIG. Holding the package 2 using the combined cushioning holding material 5, stretching two sheets with cushioning material up and down in the packaging container, and holding the package sandwiched between the sheets Therefore, a hammock method in which a package is suspended is generally used.

次に、本発明の実施の形態を図面に示した実施例に基づいて説明する。   Next, embodiments of the present invention will be described based on examples shown in the drawings.

図１は、本発明に係る梱包用衝撃緩衝材の実施例を示しており、図中符号１０は包装容器であり、２０は梱包用衝撃緩衝材、Ａは包装物である。   FIG. 1 shows an embodiment of an impact shock-absorbing material for packing according to the present invention, in which reference numeral 10 is a packaging container, 20 is an impact shock-absorbing material for packing, and A is a package.

包装容器１０は段ボール製の箱体であり、底板１１と、底板１１の各辺から立上げられた側板１２と、側板１２の各面から伸びる開閉可能な上板１３，１３，...からなり、上板１３を開放することにより、箱体上部より包装容器１０の収納部１４へ梱包用衝撃緩衝材２０や包装物Ａの出し入れが可能となっている。   The packaging container 10 is a cardboard box, and includes a bottom plate 11, a side plate 12 raised from each side of the bottom plate 11, and openable and closable upper plates 13, 13,. Thus, by opening the upper plate 13, the packing shock-absorbing material 20 and the package A can be taken in and out of the storage portion 14 of the packaging container 10 from the top of the box.

梱包用衝撃緩衝材２０は、図１に示すように上下に組み合わされることによって内部に包装物Ａの収容空間を形成する下支持部材２１と、上支持部材２２とを備えている。   As shown in FIG. 1, the packing shock-absorbing material 20 includes a lower support member 21 and an upper support member 22 that form an accommodation space for the package A inside by being combined vertically.

下支持部材２１及び上支持部材２２は、ハニカム構造を持つハニカム材２５によって形成されている。   The lower support member 21 and the upper support member 22 are formed of a honeycomb material 25 having a honeycomb structure.

ハニカム材２５は合成樹脂フィラメントを用いたスパンボンド不織布からなる帯状板材２３を多数平行に重ね合わせ、その互いに隣り合う帯状板材２３をその長さ方向に一定間隔を隔てた位置毎に、長手方向に直行する縦向きの接着部２４，２４，...により接着されるとともに、接着部２４，２４，...は千鳥状配置となっている。接着後の全帯状板材２３を互いに離反させる方向に展張することにより、図４に示すようにハニカム構造が現れる。   The honeycomb material 25 is composed of a large number of strip-like plate materials 23 made of spunbond nonwoven fabrics using synthetic resin filaments, which are stacked in parallel, and the adjacent strip-like plate materials 23 are arranged in the longitudinal direction at a certain interval in the length direction. Are bonded by the vertically-oriented vertical adhesive portions 24, 24,..., And the adhesive portions 24, 24,. By spreading all the strip-shaped plate members 23 after bonding in a direction in which they are separated from each other, a honeycomb structure appears as shown in FIG.

帯状板材２３は、軽量で水分などによる伸縮がなく、連続繊維であるため端部のほつれやほぐれがないという利点から、スパンボンド法により製造された不織布が好ましく、市販のスパンボンド不織布としては、デュポン社製の「ザーバン（登録商標）」等が例示できる。これらは本発明において好適に用いられるが、これに限定されるものではない。   The belt-like plate material 23 is lightweight, does not stretch due to moisture, etc., and is a continuous fiber. Therefore, a nonwoven fabric produced by a spunbond method is preferred because it is free from fraying and unraveling at the end. Examples include “Zurban (registered trademark)” manufactured by DuPont. These are preferably used in the present invention, but are not limited thereto.

接着部２４は、上下両縁から中央部分に向けて切込み２６が形成されていることにより、接着部２４の接着部の強固な耐座屈性に弾性を持たせている。   The adhesive portion 24 is provided with elasticity in the strong buckling resistance of the adhesive portion of the adhesive portion 24 by forming the cuts 26 from the upper and lower edges toward the central portion.

下支持部材２１は、図５に示すように上面を凹切欠した形状の包装物収容空間２８が形成され、底面には下支持部材２１の展張状態を維持させる形状保持板２９を重ね合わせている。   As shown in FIG. 5, the lower support member 21 is formed with a package accommodation space 28 having a shape in which the upper surface is recessed, and a shape holding plate 29 for maintaining the expanded state of the lower support member 21 is superimposed on the bottom surface. .

形状保持板２９は、波型加工が施された不織布が用いられ、展張した下支持部材用ハニカム材２７の展張方向に波型加工の線条３０が直交するよう下支持部材２１の底面に接着することにより、下支持部材２１をハニカム構造の現れた展張状態に固定している。   The shape retaining plate 29 is made of a non-woven fabric that has been corrugated, and is bonded to the bottom surface of the lower support member 21 so that the corrugated filaments 30 are orthogonal to the stretch direction of the expanded honeycomb member 27 for the lower support member. By doing so, the lower support member 21 is fixed in a stretched state in which the honeycomb structure appears.

上支持部材２２は、下支持部材２１の包装物収容空間２８の外側を覆うように、包装物Ａの前後に垂れ下がる側面保護部３１と、包装物Ａの上部を覆う上面保護部３２とを有しており、図６に示すように側面保護部３１、上面保護部３２、側面保護部３１の順に一体に形成されている。また、包装容器１０と包装物Ａとの空隙にあわせて形状が調節されており、本実施例において図６では側面保護部３１の高さが上面保護部３２の高さに比べ低く示されてしるが、包装物Ａの形状や空隙によって変化させている。   The upper support member 22 has a side surface protection part 31 that hangs down in front of and behind the package A so as to cover the outside of the package accommodation space 28 of the lower support member 21 and an upper surface protection part 32 that covers the upper part of the package A. As shown in FIG. 6, the side surface protection part 31, the upper surface protection part 32, and the side surface protection part 31 are integrally formed in this order. Further, the shape is adjusted in accordance with the gap between the packaging container 10 and the package A, and in this embodiment, the height of the side protection part 31 is shown lower than the height of the upper surface protection part 32 in FIG. However, it is changed depending on the shape and gap of the package A.

このように構成された梱包用衝撃緩衝材２０の使用方法を図２を使って説明する。   A method of using the packing shock-absorbing material 20 configured as described above will be described with reference to FIG.

まず包装容器１０の内部底板１１上に下支持部材２１を敷き包装物収容空間２８に包装物Ａを置く。次に上支持部材２２で上から包装物Ａの形状に合わせて覆うように展張しながら被せ、包装容器１０内の空隙をなくすようにすることで包装物Ａが動かないようにする。その後、包装容器１０の上板１３，１３，...を閉じることで梱包用衝撃緩衝材２０による梱包が完成する。   First, the lower support member 21 is laid on the inner bottom plate 11 of the packaging container 10, and the package A is placed in the package accommodation space 28. Next, the upper support member 22 is covered so as to cover the package A according to the shape of the package A, and the package A is prevented from moving by eliminating the gap in the package 10. Then, the packaging with the impact cushioning material 20 for packaging is completed by closing the upper plates 13, 13,.

次に本発明に係る梱包用衝撃緩衝材に用いる下支持部材及び上支持部材の他の実施例について、図７〜図１１を用いて説明する。尚、上述の実施例と同一の部分には同一符号を付して説明を省略する。   Next, other examples of the lower support member and the upper support member used in the shock absorbing material for packing according to the present invention will be described with reference to FIGS.

形状保持板４０は、図７に示すように、その両縁に立ち上げた係止片部４１，４１，...を一体に備え、係止片部４１，４１，...を下支持部材用ハニカム材２７の空隙４２，４２...内に挿入することによって下支持部材２１の展張状態を維持させている   As shown in FIG. 7, the shape retaining plate 40 is integrally provided with locking pieces 41, 41,... Raised on both edges thereof, and the locking pieces 41, 41,. The expanded state of the lower support member 21 is maintained by being inserted into the gaps 42 of the member honeycomb material 27.

係止片部４１，４１，...は、図８に示すように平板部４３に対して直立可能なように折り曲げ線４４を介して折り曲げ自在になっており、櫛歯状に形成されていることにより接着部２４，２４...を避けて、空隙４２，４２...に挿入される。   As shown in FIG. 8, the locking pieces 41, 41,... Are freely foldable via a fold line 44 so that they can stand upright with respect to the flat plate 43, and are formed in a comb-like shape. Therefore, it is inserted into the gaps 42, 42 ... avoiding the adhesive portions 24, 24 ....

また、形状保持板４０は下支持部材２１から着脱可能であり、使用しない際は畳まれた下支持部材用ハニカム材２７と平板状の形状保持板４０に分離出来て嵩張らず、使用時には組み立てが容易である。   Further, the shape holding plate 40 is detachable from the lower support member 21. When not in use, the shape holding plate 40 can be separated into the folded lower support member honeycomb material 27 and the flat shape holding plate 40, and is not bulky. Easy.

さらに上述の実施例で下支持部材２１上面の凹切欠した形状部分を包装物収容空間２８としたが、図９、１０の概要図のように上支持部材４５に包装物収容空間２８を備えることにより、上支持部材４５が嵌り合う溝状凹陥部４６としてもよい。尚、図９、１０は概要図でありハニカム構造を図示していないが、上述の実施例と同様にハニカム材２５を用いて形成されている。   Further, in the above-described embodiment, the concave cut-out shape portion on the upper surface of the lower support member 21 is used as the package accommodation space 28. However, the upper support member 45 includes the package accommodation space 28 as illustrated in the schematic diagrams of FIGS. Thus, a groove-like recess 46 into which the upper support member 45 fits may be used. 9 and 10 are schematic views and do not show the honeycomb structure, but they are formed using the honeycomb material 25 as in the above-described embodiment.

上支持部材４５は、図１１に示すようにその下面に溝状の包装物収容空間２８を有し、下支持部材２１の溝状凹陥部４６内にはめ合うように形成されており、下支持部材２１と同様に形状保持板を用いて展張状態を固定されている。また、図１１では形状保持板４０を用いているが形状保持板２９で展張状態を固定してもよい。   As shown in FIG. 11, the upper support member 45 has a groove-shaped package accommodation space 28 on its lower surface, and is formed so as to fit in the groove-shaped recess 46 of the lower support member 21. As in the case of the member 21, the stretched state is fixed using a shape holding plate. Further, in FIG. 11, the shape holding plate 40 is used, but the stretched state may be fixed by the shape holding plate 29.

このように構成された梱包用衝撃緩衝材２０は、下支持部材２１の溝状凹陥部４６に包装物収容空間２８を有する上支持部材４５嵌め合わせることによって包装物Ａの全周が囲まれるようになっている。   The packing shock-absorbing material 20 configured as described above is configured such that the entire periphery of the package A is surrounded by fitting the upper support member 45 having the package accommodation space 28 into the groove-like recess 46 of the lower support member 21. It has become.

尚、上述の実施例では、包装容器１０は段ボール製の箱体としたが、これの限りではなく、梱包用衝撃緩衝材２０を箱に合わせることが容易であることから、折り畳み式の箱や通い箱などでも可能である。   In the above-described embodiment, the packaging container 10 is a cardboard box. However, the packaging container 10 is not limited to this, and it is easy to match the packing shock-absorbing material 20 with the box. A returnable box is also possible.
