Description

本発明は、例えば電子機器等のような比較的重量の重い製品を梱包する際に、製品の側面や底面、上面を保護するために用いられる緩衝材に関するものである。   The present invention relates to a cushioning material used for protecting a side surface, a bottom surface, and an upper surface of a product when packaging a relatively heavy product such as an electronic device.

従来、電子機器等の梱包方法としては、段ボールケース等の外装箱と電子機器（被梱包物）との間に、輸送中の外部からの衝撃や振動を吸収する緩衝材を配置する方法が一般的である。緩衝材としては、段ボールを折畳んだものや、材料として古紙を利用したリサイクル利用が可能なパルプモールド製緩衝材等が用いられる。   Conventionally, as a packaging method for electronic devices, a buffering material that absorbs shocks and vibrations from outside during transportation is generally arranged between an outer box such as a cardboard case and the electronic device (packaged item). Is. As the cushioning material, a material obtained by folding cardboard or a pulp mold cushioning material that can be recycled using waste paper as a material is used.

しかし、重量物の梱包には段ボールや発泡樹脂製のシート材から成る基材と、基材に一体形成された、若しくは基材に固定された複数の支柱部とで構成された緩衝材が広く用いられている。   However, for packing heavy items, there is a wide range of cushioning materials composed of a base material made of corrugated cardboard or foamed resin sheet material, and a plurality of struts formed integrally with the base material or fixed to the base material. It is used.

上記の緩衝材を用いた梱包においては、通常、緩衝させたい被梱包物の側面に基材を当接させるとともに、被梱包物の側面において強度の強い部分に支柱部を配置し、基材全面で被梱包物の側面を受ける構成がとられる。   In packing using the above cushioning material, the base material is usually brought into contact with the side surface of the package object to be buffered, and the struts are disposed on the strong side portion of the side surface of the package object, The structure which receives the side of a to-be-packaged item is taken.

例えば、特許文献１には、段ボールシート製の十字状シートを換気扇取付枠にスリーブ状に巻回した後、結束材で結束する包装材が開示されており、十字状シート（基材）のホルダ面に装着された積層コア（支柱部）で換気扇取付枠のフランジ部の背面を保持することで圧縮荷重に対する耐力を向上させている。   For example, Patent Document 1 discloses a packaging material in which a cross-shaped sheet made of corrugated cardboard is wound around a ventilation fan mounting frame in a sleeve shape and then bound with a binding material. A holder for a cross-shaped sheet (base material) The strength against the compressive load is improved by holding the back surface of the flange portion of the ventilation fan mounting frame with the laminated core (post portion) mounted on the surface.

ところで、特許文献１に記載されているような基材と支柱部とで構成される緩衝材は、被梱包物である製品の外観が類似している場合は共通の緩衝材が使用されることが多い。しかし、製品の外観は類似していても、内部構成（フレーム位置）が異なると支柱部を配置可能な強度の強い部分の位置も異なる。そのため、共通の緩衝材を用いると支柱部の配置が適切でないことがあった。一方、製品毎に緩衝材を用意すると部材管理の負担が増加するとともに梱包コストも増加してしまう。   By the way, as for the shock absorbing material comprised by the base material and support | pillar part which are described in patent document 1, when the external appearance of the product which is a packaged thing is similar, a common shock absorbing material should be used. There are many. However, even if the appearances of the products are similar, the position of the strong portion where the support can be arranged also differs depending on the internal configuration (frame position). For this reason, if a common cushioning material is used, the arrangement of the column portions may not be appropriate. On the other hand, if a cushioning material is prepared for each product, the burden of member management increases and the packaging cost also increases.

また、同一の製品であっても、輸送中に緩衝不良による変形や破損等の不具合が発生した場合は支柱部の追加や位置変更が必要となるが、その場合は緩衝材の設計を変更する必要が生じ、新たな緩衝材の供給に時間を要するとともに不具合の発生した緩衝材が無駄になってしまうという問題点があった。   Even if the product is the same, if a defect such as deformation or breakage occurs due to defective buffering during transportation, it is necessary to add or change the position of the column. In that case, change the buffer material design. There is a problem that the necessity arises, it takes time to supply a new cushioning material, and the cushioning material in which the malfunction occurs is wasted.

そこで、特許文献２には、井桁状に組み合わされた複数の仕切り板（基材）に、緩衝ブロック（支柱部）を装着するための切り込みを長手方向に沿って複数個所に備えた梱包箱が開示されている。特許文献２の構成によれば、仕切り板に対し任意の箇所に任意の個数の緩衝ブロックを装着できるため、被梱包物夫々に対応した専用の緩衝材を用いることなく、緩衝材を共通化することができる。   Therefore, Patent Document 2 discloses a packaging box in which a plurality of partition plates (base materials) combined in a cross beam shape are provided with a plurality of cuts along the longitudinal direction for mounting buffer blocks (supports). It is disclosed. According to the configuration of Patent Document 2, since any number of buffer blocks can be attached to any part of the partition plate, the buffer material is shared without using a dedicated buffer material corresponding to each packaged item. be able to.

特開２００５−３２４８００号公報JP-A-2005-324800 特開２００８−３０８０７号公報JP 2008-30807 A

しかし、特許文献２の方法では、井桁状に組み合わせた仕切り板の端縁が被梱包物に当接するため、被梱包物の緩衝させたい面を広く受けることができず、被梱包物によっては十分な緩衝効果が得られない場合があった。また、緩衝ブロックは井桁状の仕切り板の周縁に沿って配置されるため、被梱包物の中央部に緩衝ブロックを配置することは困難であった。   However, in the method of Patent Document 2, since the edges of the partition plates combined in the form of a cross-beam abut against the object to be packed, the surface to be buffered cannot be widely received, and depending on the object to be packed, it is sufficient. In some cases, a sufficient buffering effect could not be obtained. Moreover, since a buffer block is arrange | positioned along the periphery of a grid-like partition plate, it was difficult to arrange | position a buffer block in the center part of the to-be-packaged thing.

本発明は、上記問題点に鑑み、外観が類似する被梱包物に対して共通して使用でき、被梱包物の内部構成に応じて支柱部の個数や配置を簡単に変更可能な緩衝材を提供することを目的とする。   In view of the above-described problems, the present invention provides a cushioning material that can be used in common for objects to be packaged with similar appearances, and can easily change the number and arrangement of support columns according to the internal configuration of the object to be packaged.

以下、図面を参照しながら本発明の実施形態について説明する。図１は、本発明の第１実施形態に係る緩衝材１の平面図である。緩衝材１は、電子機器（被梱包物）７の側面７ａ（図５参照）に対向する段ボールシート製の基材２と、基材２の側面７ａとの対向面と反対側の面の略中央部に固定される段ボールシートを折り曲げて形成された支柱部３ａとで構成されており、基材２の撓みにより電子機器７への衝撃の伝達を緩和する。支柱部３ａは上部が開口したポケット状に形成されており、内部に付属部品を収納可能となっている。また、基材２の複数箇所（ここでは左右２箇所ずつの計４箇所）には平面視略Ｕ字状の切り込み４が形成されており、切り込み４で囲まれた部分が切り起こし片４ａ（図２参照）となる。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the cushioning material 1 according to the first embodiment of the present invention. The cushioning material 1 is an abbreviation of the surface opposite to the surface facing the side surface 7a of the base material 2 and the side surface 7a of the base material 2 facing the side surface 7a (see FIG. 5) of the electronic device (packaged object) 7. It is composed of a column portion 3 a formed by bending a corrugated cardboard sheet fixed to the center portion, and the transmission of impact to the electronic device 7 is mitigated by the bending of the base material 2. The column part 3a is formed in a pocket shape with an open top, and can accommodate accessory parts inside. In addition, a plurality of U-shaped cuts 4 in a plan view are formed at a plurality of locations on the base material 2 (here, a total of four locations on each of the left and right sides), and a portion surrounded by the cuts 4 is cut and raised pieces 4a ( (See FIG. 2).

図２は、第１実施形態の緩衝材１に支柱部３ｂを追加した状態を示す平面図、図３は、第１実施形態の緩衝材１に用いられる支柱部３ｂの斜視図、図４は、図２の上方から見た緩衝材１の部分側面図である。図３に示すように、支柱部３ｂは、柱状の緩衝部５と、緩衝部５の一端から鍔状に突出する平板状の支持部６とで構成されている。   FIG. 2 is a plan view showing a state in which a column 3b is added to the cushioning material 1 of the first embodiment, FIG. 3 is a perspective view of the column 3b used for the cushioning material 1 of the first embodiment, and FIG. FIG. 3 is a partial side view of the cushioning material 1 as viewed from above in FIG. 2. As shown in FIG. 3, the support column portion 3 b includes a columnar buffer portion 5 and a flat plate-like support portion 6 that protrudes from one end of the buffer portion 5 in a bowl shape.

そして、図３のような支柱部３ｂを２個用意し、図４に示すように、各支柱部３ｂの支持部６を、それぞれ基材２と切り込み４の内側を切り起こして形成される切り起こし片４ａとの間に差し込むことにより、図２に示すように支柱部３ａの両側に支柱部３ｂが追加された緩衝材１となる。   Then, two struts 3b as shown in FIG. 3 are prepared. As shown in FIG. 4, the support 6 of each strut 3b is cut and formed inside the base material 2 and the cut 4 respectively. By inserting it between the raised pieces 4a, the cushioning material 1 is obtained in which the column portions 3b are added on both sides of the column portion 3a as shown in FIG.

緩衝部５は段ボールシートを積層して形成されており、支持部６は緩衝部５よりも幅の広い段ボールシートを緩衝部５の一端に貼り付けて形成されている。なお、緩衝部５は段ボールシートを基材２に対し垂直に積層して形成しても良いし、発泡スチロールや発泡ポリウレタン等の樹脂材料で形成しても良いが、緩衝部５及び支持部６を段ボールシートで形成することにより、基材２、支柱部３ａを含めた緩衝材１全体が段ボールシート製となるため、廃棄時に基材２と支柱部３ａ、３ｂとの分別作業が不要でリサイクルが可能であり、環境負荷も少ない緩衝材１となる。   The buffer portion 5 is formed by stacking cardboard sheets, and the support portion 6 is formed by sticking a cardboard sheet having a width wider than that of the buffer portion 5 to one end of the buffer portion 5. The buffer portion 5 may be formed by stacking corrugated cardboard sheets perpendicular to the base material 2 or may be formed of a resin material such as foamed polystyrene or foamed polyurethane. By forming the cardboard sheet, the entire cushioning material 1 including the base material 2 and the support column 3a is made of a cardboard sheet, so that the separation work between the base material 2 and the support columns 3a and 3b is unnecessary at the time of disposal. The buffer material 1 is possible and has a low environmental load.

次に、本実施形態の緩衝材１の使用方法について説明する。図５及び図６は、それぞれ図１及び図２に示した第１実施形態の緩衝材１を、電子機器７の側面７ａに沿って装着し、外装箱１０内に梱包した状態を上方から見た部分側面図である。図５に示す電子機器７は、側面（被緩衝面）７ａの左右の側縁部近傍の領域Ｒ（図５にハッチングで表示）にはフレームが存在せず、強度が弱くなっている。そのため、強度の弱い領域Ｒに対向するように支柱部を配置すると、荷重や衝撃等の外力が加えられた際に領域Ｒの変形や破損が生じるおそれがある。   Next, the usage method of the shock absorbing material 1 of this embodiment is demonstrated. 5 and 6 show the state in which the cushioning material 1 of the first embodiment shown in FIGS. 1 and 2 is mounted along the side surface 7a of the electronic device 7 and packed in the outer box 10 from above. FIG. The electronic device 7 shown in FIG. 5 has no frame in the region R (shown by hatching in FIG. 5) in the vicinity of the left and right side edges of the side surface (buffered surface) 7a, and the strength is weak. For this reason, when the support column is disposed so as to face the weak region R, the region R may be deformed or damaged when an external force such as a load or an impact is applied.

そこで、図５では、図１に示した支柱部３ｂの追加されていない緩衝材１を用い、基材２の略中央部から突出する支柱部３ａだけを外装箱１０の内壁面に当接させている。この構成によれば、領域Ｒに対向する位置には支柱部が存在しないため、側板１０ａ方向から外力が加えられても領域Ｒに荷重が掛からない。従って、側面７ａにおいて強度の弱い領域Ｒの変形や破損を防止することができる。   Therefore, in FIG. 5, the cushioning material 1 to which the supporting column part 3 b shown in FIG. 1 is not added is used, and only the supporting column part 3 a protruding from the substantially central part of the base material 2 is brought into contact with the inner wall surface of the outer box 10. ing. According to this configuration, since there is no column portion at a position facing the region R, no load is applied to the region R even if an external force is applied from the side plate 10a direction. Therefore, deformation and breakage of the weak region R on the side surface 7a can be prevented.

一方、図６に示す電子機器７は、図５の電子機器７と外観形状はほぼ同じであるが、内部構造が異なっており、側面７ａの左右の側縁部近傍にはフレーム８が存在する。そのため、側面７ａの左右の側縁部近傍の強度が強くなっている。   On the other hand, the electronic device 7 shown in FIG. 6 has substantially the same external shape as the electronic device 7 of FIG. 5, but the internal structure is different, and the frame 8 exists in the vicinity of the left and right side edges of the side surface 7a. . Therefore, the strength in the vicinity of the left and right side edges of the side surface 7a is increased.

そこで、図６では、図２に示した支柱部３ｂの追加された緩衝材１を用い、基材２の略中央部から突出する支柱部３ａと、支柱部３ａの両側の支柱部３ｂとを外装箱１０の内壁面に当接させている。この構成によれば、側面７ａの複数の箇所が支柱部３ａ、３ｂで支持されるため、外力を十分に緩衝することができる。   Therefore, in FIG. 6, the cushioning material 1 to which the supporting column part 3 b shown in FIG. 2 is added is used, and the supporting column part 3 a protruding from the substantially central part of the base material 2 and the supporting column parts 3 b on both sides of the supporting column part 3 a The outer wall is in contact with the inner wall surface of the outer box 10. According to this structure, since the some location of the side surface 7a is supported by the support | pillar part 3a, 3b, an external force can fully be buffered.

以上説明したように、本実施形態の緩衝材１によれば、基材２に対し支柱部３ｂを着脱可能であるため、電子機器７の側面７ａの強度等に応じて支柱部３ｂを装着しない図１の構成と、支柱部３ｂを追加した図２の構成とを選択することができる。従って、外観が類似する電子機器７に対し共通の緩衝材１を用いることができ、部材管理の負担や梱包コストも低減できる。   As described above, according to the cushioning material 1 of the present embodiment, since the support 3b can be attached to and detached from the base material 2, the support 3b is not mounted according to the strength of the side surface 7a of the electronic device 7 or the like. The configuration shown in FIG. 1 and the configuration shown in FIG. 2 to which the column portion 3b is added can be selected. Therefore, the common cushioning material 1 can be used for the electronic devices 7 having similar appearances, and the burden of member management and packing costs can be reduced.

図７は、本発明の第２実施形態に係る緩衝材１の平面図、図８は、緩衝材１の支柱部３ｂ周辺の部分断面図（図７のＡＡ′矢視断面図）、図９は、第２実施形態の緩衝材１に用いられる支柱部３ｂの平面図である。本実施形態の緩衝材１では、基材２に対し着脱可能な２つの支柱部３ｂが設けられており、基材２に固定される支柱部３ａは設けられていない。また、基材２に形成された切り込み４は、互いにＵ字の湾曲部が向きあうように対をなしており、この対をなす切り込み４が基材２の左右の側端縁近傍に複数対形成されている。   7 is a plan view of the cushioning material 1 according to the second embodiment of the present invention, FIG. 8 is a partial sectional view around the support column 3b of the cushioning material 1 (cross-sectional view taken along the line AA ′ in FIG. 7), FIG.
