Description

【0001】
【発明が属する技術分野】
本発明は、市販の組み立て運搬用具である紙製やプラスチック製の通函を緩衝性のある運搬用具として使用するための薄膜包容緩衝機構要素に関する。
【0002】
【従来の技術】
通常、緩衝性通函は生産工場の機種ごとに誂えるのが常識であり、汎用的に繰り返し再使用できるものは殆ど無かった。普通はクッションパッキングを往路搬送時の消耗品として用いるものであって、このクッション用パッキングは復路には廃棄されるものとされている。
【0003】
また、緩衝・耐衝撃とリユース・再使用・リサイクルの語句組み合わせによって検索できる発明品や考案品が極めて少ないことが緩衝性通函への関心の低さを証明しているのかも知れないが、在来のクッションパッキング材の破棄や焼却に伴う環境負荷の増大等のマイナスイメージに加え、企業コスト削減を志向する社会情勢からも許されなくなってきている。
【0004】
緩衝性包装用容器に関する特許・実用新案である特開平06−293363、特開平10−338265、特開平10−095343などでは上述のクッションパッキングまたは極薄プラスチックフィルム製空気袋によるものであり、かつ通函には不適当である。
【0005】
また、実用新案306220では箱内に緩衝材として布を貼った専用仕切構造物を内蔵せしめ緩衝パッキング不要化を期している。また、実用新案3063383では箱を3分割し、2つの箱の片面にプラスチックフィルムを張って相対抗せしめ外箱で緊縛することでパッキングレス化を図り、いずれの考案も、クッションパッキング材としてのスポンジ材やクッション材や空気封入シートやマットまたはそれらに変わる消耗品の不要化に成功している。そして、通函として使用できるものに見える。しかし、梱包搬送品の重量・大小・形状に大きく制限され、搬送の往路と復路共に梱包サイズが変わらない点が惜しまれる。
【0006】
【発明が解決しようとする課題】
本発明が解決しようとする問題は、
▲1▼ 消耗品としてのクッションパッキングを使用しないで済む汎用性と緩衝機能のある通函であって、
▲2▼ 復路のさいの空搬送時には往路時に比して搬送容積は四半分以下であり、
▲3▼ 空搬送重量は一割以下を志向すると共に、
▲4▼ 数百回を越える繰り返し使用、
の4課題である。
【0007】
これらの要件は、消耗品を排出せずかつ廃棄時環境負荷要因にならないことを前提としているほかに、搬送品の大小・軽重・外形にある程度の範囲で左右されることなく、搬送物を緊縛できると共に、衝撃を受けたさい通函内壁に衝突しない程度に移動を許し、衝撃力を緩和できなくてはならない機能の具備を要求し、社会的要請に応えることを目指している。
【0008】
【課題を解決するための手段】
本発明は、上記課題に対応して1枚の長いエラスチックな薄膜を二つ折りにして、その折り目に位置せしめる軸棒と薄膜を折り重ねた結果としての端部に二つ重なる軸棒とを緊張せしめ、薄膜を折り重ねた中間に搬送品を挟み込むものであるが、これでは、エラスチック薄膜の幅方向に衝撃外力を受けた時、搬送品が滑動し、通函内壁に衝突するのを防止できない。このために請求項に示した3手段によって膜自他の弾性強度を倍から数倍強化することで、エラスチック薄膜の幅方向に衝撃外力を受けた時でも搬送品の薄膜幅方向への運動量を通函内壁に達しない程度に削減できる。
【0009】
このようにすることによって、市販の各種運送容器例えばダンボール箱・カートンボックス・プラスチック製コンテナ・木箱・カーゴコンテナ・ボックスパレットなどをそのまま緩衝用搬送容器として転用でき、かつ、搬送往路復路のいずれにおいても廃棄物を発生することなく、また、復路においては容積の減少すなわち搬送コストの低下が出来るものである。
【0010】
【発明の実施の形態】
図1:薄膜包容緩衝機構要素の使用例を示した斜視図を主として、図2および図3と図4の各図で、本発明実施の詳細を説明する。
【0011】
図1の斜視図は組み立て式ダンボール箱11または折り畳み式プラスチック製コンテナ13を含む外箱10の左右前面と上の蓋を外した形すなわち三方向の側面を外した形で斜視したものである。外箱10の切断面はハッチングされて箱の外面を示している。その内規奥側に、上段下段に浮押側板31、中段に伸張側板33を配して、その内側手前に同じものを相対抗するよう配置してある。なお、手前側のもの上段の側板31と手前両側の幅板34および中段の側板33は仮想線で図示し、梱包対象40の保持状況が明示されるようにしてある。
【0012】
箱内部の左方中段に上述下段の浮押側板31前後両側にまたがるように折り返し板32を置き、その反対側である右手に薄膜包容緩衝機構要素20がその角管軸棒25によって浮押側板31前後両側右端にまたがりながら下段幅板33に載るように架けられ、薄膜包容緩衝機構要素20のエラスチック薄膜21が右側中段下端から反対側の折り返し板32の外側を介して右方に折り返され、右側中段上端の角管軸棒25に戻るように伸張懸垂される。なお、上段と下段には幅板34が押し込まれ、浮押側板31とともに外箱10の内壁4周に密着するよう構成され、外箱の強度を高めるよう機能している。
【0013】
搬送すべき梱包対象40は左手の折り返し板32で反転二つ折りされた薄膜包容緩衝機構要素20の中央にエラスチック薄膜21によって上下左右前後を包容されかつ薄膜平面で緊縛されたかのように懸垂される。なお、図1では薄膜包容緩衝機構要素20をポリウレタン系薄膜あるいはポリグリコールグルタミン酸系プラスチック薄膜などの透明シートとして描画してある。この状態は図2:薄膜包容緩衝機構要素使用時の補助部品配置を示す正面図と図3:薄膜包容緩衝機構要素使用時の補助部品配置を示す側面図に示すように、梱包対象40が透明な膜のハンモックで上下を挟んで吊っているかのような状態とも言える。
【0014】
この梱包対象40の固定状況は、図2:薄膜包容緩衝機構要素使用時の補助部品配置を示す正面図と図3:薄膜包容緩衝機構要素使用時の補助部品配置を示す側面図での両図で示すように、仮想線で描いた外箱10の内規で囲まれた空間内に閉じこめられ相互の配置位置の自由度を失って、エラスチック薄膜21の幅・厚さ・弾性の属性の結果としての張力によって定まり、薄膜包容緩衝機構要素20の伸張方向は図2に矢印28で示したエラスチック薄膜21の張力の分力により角管軸棒25方向にも折り返し板32方向にも多少滑動は許されるものの滑動量に伴い大きくなる反力によって制限される。
【0015】
図3で示す矢印28は、梱包対象40の高さの三分の一以下に設定された折り返し板32の上下高さを越えて上下左右前後から包容する固定圧力を意味する。しかし、これは折り返し板32によって反転された薄膜包容緩衝機構要素20の宙吊りになった形で、エラスチック薄膜21の横幅方向への滑動を抑える力は弱い。このために包み代を深く出来るような幅をエラスチック薄膜21に与えると共に、横幅方向外端部を請求項に示し後述する三通りの手段のいずれかによって大きく補強し、エラスチック薄膜21の横幅外側への滑動を制限している。また、エラスチック薄膜21の横幅方向両側の空間は薄膜の幅並びに厚さと伸張長さと梱包対象40の荷重並びに対衝撃荷重設定で決まる揺れを許す範囲に設けておくものとする。浮押側板31をダンボール製などどしたさいの緩衝機能は高いと期待できないからである。
【0016】
図1の実施例構造を斜視図で示したものが図4:実施例図1の分解構成説明図である。この図で示す物は本発明の単純な実施例における全部品を示している。これについて詳述する。当図では外箱10の代表例として組み立て式ダンボール箱11および12と、折り畳み式プラスチック製コンテナ13および14を示している。非使用時の組み立て式ダンボール箱12と、非使用時の折り畳み式プラスチック製コンテナ14とは共に畳まれた状態を実線で示し、組み上げた状態を二点鎖線で図示し使用時の組み立て式ダンボール箱11と使用時の折り畳み式プラスチック製コンテナ13として図4最上段に描いた。この二つについてはこの下の補助部品の半分の縮尺で示してある。
【0017】
図4はまた梱包時の使用手順に従って上段から下段へと配列し表示した。梱包手順に従って、市販の組み立て運搬用具であるダンボール製やプラスチック製の通函を緩衝性のある運搬用具として使用できるように梱包するかを薄膜包容緩衝機構要素と補助部品の構成を以下に説明している。これら当図における30番台の補助部品は全てダンボール紙工品として作図してあるが、材料は本発明を左右しないので詳細記述を省略する。
【0018】
組み立てたダンボール箱11または折り畳み式プラスチック製コンテナ13すなわち外箱10を開き、上中下の三段に重ねて行く。最初に浮押側板31を2ヶ内側長手方向内壁に挿入し、さらにそれに直交せしめるように他の内側内壁に幅板34を2ヶ挿入して、内壁四周に密着させて下段と成す。
【0019】
中段は、その上に伸張側板33を2ヶ内側長手方向内壁に挿入して、薄膜包容緩衝機構要素20の一端にある角管軸棒25を伸張側板33の一端にまたがらせておいて、外箱10内壁反対側に薄膜包容緩衝機構要素20の他端を広げ、折り返し板32でエラスチック薄膜21中央部を押し込むかのように内壁反対側に押し込み、エラスチック薄膜21中央部に梱包対象40を置き、薄膜包容緩衝機構要素20のエラスチック薄膜21を梱包対象40の上に被せながら折り返し残る端の角管軸棒25を既挿入済み角管軸棒25の上方向に重ねるように挿入する。これで、中段の設置が終わる。
【0020】
最後に浮押側板31を2ヶ内側内壁に挿入し、さらにそれに直交せしめるように他面内壁両側に幅板34を2ヶ押し込み、上段と成して、蓋をし、封緘する。以上により、上段と下段は梱包対象40を宙づりにする中段部分を支えながら、箱の外力による変形をも緩衝でき、図1・図2・図3に示すような梱包対象40の包容状態を形成し、運搬中の緩衝機能を達成できる。
【0021】
図4に示したように、薄膜包容緩衝機構要素20は一見、エラスチック薄膜21の両端に角管軸棒25を取り付けただけの掛け軸状を成しているが、この一つを折り返し板32や単なる軸棒で折り返し反転させて梱包対象40を挟み込み箱内に宙づりにする単純な実施例を示したが、この方式には、宙づりにされた薄膜包容緩衝機構要素20が伸張方向の法線側すなわち横揺れのさい別方向への衝撃に比べる時緩衝機能が弱く吊った梱包対象40が薄膜包容緩衝機構要素20横幅外に逸脱することを許し易い。
【0022】
これへの対策としては、二つの解決法がある。その1は、幅のある折り返し板32を単なる角管または丸管軸棒一本に置き換える方策でエラスチック薄膜21による膜幅側の包み被せる包容量を大きくするのが単純で効果的である。その2は、エラスチック薄膜21の幅を広げ梱包対象40の横幅方向を深く包容する方策がある。しかし、始めの対策では、 搬送時に重心の偏った包対象40には対処しにくい。 また第二案では、梱包外箱の大きさが増える欠点がある。これらを避けるために本発明では、諸試行を重ねて、エラスチック薄膜21の幅方向両端について請求項で述べた三手段を有効と判断したので、以下に詳述する。
【0023】
図5:請求項1の手段による薄膜包容緩衝機構要素の断面図で示したように、エラスチック薄膜21の幅方向両端を長手方向の中心線側に折り返す。この折り返し幅はエラスチック薄膜21の全幅の5から20%程度が妥当であり、この折り返しにより薄膜包容緩衝機構要素20の横幅方向加振時における耐衝撃性は膜厚二倍以上で約8倍近くに上昇した。また、梱包対象40を包容する機能も高まる。長手方向両端に接着固定する角管軸棒25は円形パイプでも構わないものの固定伸張時の伸張弾性すなわち梱包対象包容力の調整が巻き取り量によって設定できるため有効である。もっともこのためには、エラスチック薄膜21の長手方向両端部は図5・図6・図7に共通して示すように両面接着テープ26などで角管軸棒25表面に接合する必要がある。
【0024】
図6:請求項2の手段による薄膜包容緩衝機構要素の断面図である。エラスチック薄膜21の幅方向両端を長手方向の中心線側に折り返す。さらに折り返し内の横幅端側にエラスチックな紐23例えばポリウレタン繊維紐またはゴム紐ないし金属製細巻き多重コイルスプリング紐など梱包対象40に合わせて選ぶ。この内装した紐はエラスチック薄膜21に接合させる必要はない。
【0025】
この紐の内装により、折り返し幅による薄膜包容緩衝機構要素20の横幅方向加振時における耐衝撃性は折り返し膜厚効果以上に大きくかつ広範囲で約百倍近くに上昇した。また、梱包対象40を包容する能力も高まるが、エラスチック薄膜21面の梱包対象40表面凹凸への馴染みが高弾力紐ほど低下した。長手方向両端に接着固定する軸棒については前の手段とは変わらない。
【0026】
図7:請求項3の手段による薄膜包容緩衝機構要素の断面図である。エラスチック薄膜21の幅方向両端を長手方向の中心線側に折り返す。この折り返し代内に弾性に富む帯24を包むもので、例えばゴムバンドや多重帯状成形金属バンドあるいはポリウレタン繊維バンド等がある。これによる効果は前述第二手段より多少劣るがさして変わらない。また、長手方向両端に接着固定する軸棒についても前の手段とは大差ない。
【0027】
【発明の効果】
上記に説明したように本発明は、
(1)市販のダンボール箱・プラスチックコンテナ・ボックスパレットなどをそのまま緩衝性搬送外箱として利用できる。通函についても同じ。
(2)梱包対象40が外箱10より多少小さければその軽重大小を問わない。
(3)消耗品としてのクッションパッキング材不要。
(4)通函として空返送時の搬送容積は激減できる。
(5)繰り返し使用可能。
(6)同一サイズであっても梱包対象40を包容保持する弾力を調整できる。
(7)材料選択次第では自然環境に対する負荷増大要因を持たない。
(8)運用者から見て搬送費用と維持コスト削減につながる。
の8効果を有するものと判断できる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin-film-encapsulation buffer mechanism element for using a paper or plastic container, which is a commercially available assembling / transporting tool, as a buffering transporting tool.
[0002]
[Prior art]
Normally, it is common sense to customize the buffering box for each model of the production plant, and there is almost no general-purpose reusable box. Normally, the cushion packing is used as a consumable at the time of forward transportation, and this cushion packing is to be discarded on the return path.
[0003]
Also, the fact that there are very few inventions and inventions that can be searched by word combinations of cushioning and shock resistance and reuse, reuse and recycling may prove the low interest in cushioning mail boxes, In addition to negative images such as an increase in the environmental burden associated with the destruction and incineration of conventional cushion packing materials, it has become unacceptable due to the social situation that seeks to reduce corporate costs.
[0004]
Japanese Patent Application Laid-Open Nos. 06-293363, 10-338265, and 10-095343, which are patents and utility models related to the cushioning packaging container, use the above-mentioned cushion packing or an air bag made of an ultra-thin plastic film. Not suitable for boxes.
[0005]
Further, in the utility model 306220, a dedicated partition structure in which a cloth is stuck as a cushioning material is built in the box, thereby eliminating the need for buffer packing. Further, in the utility model 3063383, the box is divided into three parts, a plastic film is stretched on one side of the two boxes, and the two boxes are tightly tied together with an outer box to reduce packing, and in each case, a sponge as a cushion packing material is used. It has succeeded in eliminating the need for materials, cushioning materials, air-filled sheets and mats, or consumables that replace them. And it looks like it can be used as a box. However, the weight, size, and shape of the packaged and conveyed products are greatly restricted, and the point that the packing size does not change on both the forward path and the return path of the transportation is regretted.
[0006]
[Problems to be solved by the invention]
The problem that the present invention seeks to solve is:
(1) A versatile and shock-absorbing mail box that does not require the use of cushion packing as a consumable.
(2) During empty return on the return path, the transport volume is less than a quarter of that on the forward path,
(3) While aiming for less than 10% of empty transport weight,
(4) Repeated use more than several hundred times,
These are the four issues.
[0007]
These requirements are based on the premise that consumables are not discharged and do not cause an environmental burden at the time of disposal. It aims to respond to social demands by providing functions that must be able to move as much as possible and not to collide with the inner wall of the container when impacted, and must be able to reduce the impact force.
[0008]
[Means for Solving the Problems]
According to the present invention, a long elastic thin film is folded in two in response to the above problem, and a shaft rod positioned at the fold and a shaft rod overlapping at an end portion obtained by folding the thin film are tensioned. At the very least, the transport product is sandwiched in the middle of the folded thin film, but this does not prevent the transport product from sliding and colliding with the inner wall of the container when receiving an external impact in the width direction of the elastic thin film . For this purpose, the elasticity of the film itself is strengthened by a factor of two to several times by the three means described in the claims, so that the momentum of the conveyed product in the width direction of the thin film can be reduced even when an external force is applied in the width direction of the elastic thin film. It can be reduced to the extent that it does not reach the inner wall of the box.
[0009]
By doing in this way, various types of commercially available transport containers such as cardboard boxes, carton boxes, plastic containers, wooden boxes, cargo containers, box pallets, etc. can be diverted as they are as buffer transport containers, and in any of the forward and return routes. No waste is generated, and the volume on the return path, that is, the transportation cost can be reduced.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a perspective view showing an example of use of a thin-film-enclosure buffer mechanism element, and the details of the embodiment of the present invention will be described mainly with reference to FIGS. 2, 3 and 4.
[0011]
The perspective view of FIG. 1 is a perspective view of the outer box 10 including the assembled cardboard box 11 or the foldable plastic container 13 with the left and right front faces and the upper lid removed, that is, with the side faces in three directions removed. The cut surface of the outer box 10 is hatched to show the outer surface of the box. On the back side of the inner rule, a floating push side plate 31 is arranged in an upper stage lower stage, and an extension side plate 33 is arranged in a middle stage, and the same thing is arranged in front of the inner side so as to oppose each other. The upper side plate 31 on the front side, the width plate 34 on both sides on the front side, and the middle side plate 33 are shown by imaginary lines so that the holding state of the packing object 40 is clearly shown.
[0012]
A folded plate 32 is placed in the middle left of the box so as to straddle the front and rear sides of the lower floating plate 31, and the thin film buffering mechanism element 20 is held by the square tube shaft 25 on the opposite right side. 31 is stretched so as to rest on the lower width plate 33 while straddling the right and left ends on both sides, and the elastic thin film 21 of the thin film-encapsulating buffering element 20 is folded rightward from the lower right end of the middle middle stage through the outside of the folded plate 32 on the opposite side, It is extended and suspended so as to return to the square tube shaft 25 at the upper end of the right middle stage. In addition, the width plate 34 is pushed into the upper stage and the lower stage, and the width plate 34 is configured to be in close contact with the periphery of the inner wall 4 of the outer box 10 together with the floating side plate 31, and functions to increase the strength of the outer box.
[0013]
The packing object 40 to be conveyed is wrapped up and down, left and right and front and back by the elastic thin film 21 at the center of the thin film enclosing buffer mechanism element 20 which is folded in half by the folding plate 32 of the left hand, and is hung as if bound by the thin film plane. In FIG. 1, the thin film containing buffering mechanism element 20 is drawn as a transparent sheet such as a polyurethane thin film or a polyglycol glutamate plastic thin film. In this state, the packing object 40 is transparent as shown in FIG. 2: a front view showing the arrangement of auxiliary parts when using the thin-film encapsulation buffer element, and FIG. It can be said that it is as if it is hung up and down with a hammock of a natural film.
[0014]
FIG. 2 is a front view showing the arrangement of auxiliary parts when using the thin-film encapsulation buffer element, and FIG. 3 is a side view showing the arrangement of auxiliary parts when using the thin-film encapsulation buffer element. As shown by, as a result of the attributes of the width, thickness, and elasticity of the elastic thin film 21, they are confined in the space surrounded by the inner rule of the outer box 10 drawn by the imaginary line and lose the degree of freedom of the mutual arrangement position. The extension direction of the thin film-encapsulating buffer mechanism element 20 is allowed to slide slightly in the direction of the square tube shaft 25 and in the direction of the folded plate 32 by the component force of the elastic thin film 21 shown by the arrow 28 in FIG. Is limited by the reaction force that increases with the amount of sliding.
[0015]
An arrow 28 shown in FIG. 3 indicates a fixed pressure that covers the vertical direction of the folded plate 32 from above, below, right, left, and front over the vertical height of the folded plate 32 set to be less than or equal to one third of the height of the packing object 40. However, this is a form in which the thin film containing buffer mechanism element 20 inverted by the folding plate 32 is suspended in the air, and the force for suppressing the sliding of the elastic thin film 21 in the width direction is weak. To this end, the elastic thin film 21 is given a width that allows a deeper wrapping margin, and the outer end in the width direction is greatly reinforced by any of the three means described in the claims and described later, so as to extend outward from the width of the elastic thin film 21. Sliding is restricted. The space on both sides in the horizontal width direction of the elastic thin film 21 is provided in a range that allows a swing determined by the width and thickness of the thin film, the extension length, the load of the package 40, and the setting of impact load. This is because it is not possible to expect a high buffering function when the floating push side plate 31 is made of cardboard or the like.
[0016]
FIG. 4 is an exploded view of the embodiment of FIG. 1 in a perspective view. What is shown in this figure shows all the components in a simple embodiment of the invention. This will be described in detail. In this figure, assembling cardboard boxes 11 and 12 and folding plastic containers 13 and 14 are shown as typical examples of the outer box 10. The assembled cardboard box 12 when not in use and the foldable plastic container 14 when not in use are shown by a solid line, and the assembled state is shown by a two-dot chain line, and the assembled cardboard box in use is shown. 11 and the foldable plastic container 13 at the time of use are shown at the top of FIG. The two are shown at half the scale of the auxiliary parts below.
[0017]
FIG. 4 also shows an arrangement from the upper stage to the lower stage according to the use procedure at the time of packing. In accordance with the packaging procedure, the configuration of the thin-film containment buffering mechanism element and auxiliary parts will be described below as to whether a commercially available assembling and carrying tool, a cardboard or plastic box, should be packed so that it can be used as a buffering carrying tool. ing. Although all the auxiliary parts in the thirties in this drawing are drawn as corrugated cardboard products, the detailed description is omitted because the material does not affect the present invention.
[0018]
The assembled cardboard box 11 or the foldable plastic container 13, that is, the outer box 10 is opened, and the upper box, the lower box, and the lower box are stacked. First, two floating plates 31 are inserted into the inner longitudinal inner wall, and two width plates 34 are inserted into the other inner wall so as to be perpendicular to the inner wall, and are brought into close contact with the inner wall on four sides to form a lower stage.

In the middle stage, the extension side plates 33 are inserted into the two inner longitudinal inner walls, and the square tube shaft 25 at one end of the thin film-encapsulating buffer mechanism element 20 is straddled over one end of the extension side plate 33. The other end of the thin-film-encapsulating buffer mechanism element 20 is spread on the opposite side of the inner wall of the outer box 10, and is pushed into the opposite side of the inner wall as if the central part of the elastic thin film 21 is pushed by the folded plate 32, and the packing object 40 is placed in the center of the elastic thin film 21. Then, the elastic thin film 21 of the thin-film-encapsulating buffer mechanism element 20 is inserted over the packaged object 40 so that the square tube shaft 25 at the end that is folded back while being overlaid on the packing object 40 is overlapped with the square tube shaft bar 25 already inserted. This completes the middle installation.
[0020]
Finally, two floating plates 31 are inserted into the two inner walls, and two width plates 34 are pushed into both sides of the other inner wall so as to be perpendicular to the inner walls. As described above, the upper and lower tiers can support the middle tier for suspending the packing object 40 and also buffer the deformation due to the external force of the box, and form the enclosing state of the packing object 40 as shown in FIGS. 1, 2, and 3. Thus, a buffer function during transportation can be achieved.
[0021]
As shown in FIG. 4, at first glance, the thin-film-encapsulating buffering mechanism element 20 has a hanging shaft shape in which square tube rods 25 are attached to both ends of the elastic thin film 21. Although a simple embodiment in which the object to be packed 40 is suspended in the sandwiching box by turning over and turning over with a simple shaft rod has been described, this method includes a method in which the suspended thin-film-encapsulating buffer mechanism element 20 is placed on the normal side in the extension direction. That is, it is easy to allow the hung packaging object 40 to deviate outside the width of the thin-film-enclosure buffer mechanism element 20 because the buffering function is weaker than the impact in the other direction during the rolling.
[0022]
There are two solutions to this. The first method is to replace the wide folded plate 32 with a simple square tube or a single round tube shaft, and it is simple and effective to increase the enclosing capacity of the elastic thin film 21 on the film width side. Second, there is a method of expanding the width of the elastic thin film 21 and deeply covering the width direction of the package 40. However, the first countermeasure is difficult to deal with the packaging object 40 having a biased center of gravity during transport. The second alternative has the disadvantage that the size of the outer packaging box increases. In order to avoid these problems, in the present invention, it has been determined that the three means described in the claims are effective at both ends in the width direction of the elastic thin film 21 through repeated trials.
[0023]
FIG. 5: As shown in the cross-sectional view of the thin-film-enclosing buffer mechanism element according to the first aspect, both ends in the width direction of the elastic thin film 21 are folded back toward the center line in the longitudinal direction. The folded width is appropriately about 5 to 20% of the entire width of the elastic thin film 21. By this folded, the shock resistance of the thin film-encapsulating cushioning element 20 at the time of vibration in the transverse direction is more than twice the film thickness and about 8 times. Rose. In addition, the function of enclosing the packing target 40 is also enhanced. Although the square pipe shaft rod 25 bonded and fixed to both ends in the longitudinal direction may be a circular pipe, it is effective because the extension elasticity at the time of fixed extension, that is, the adjustment of the packaging target packaging force can be set by the winding amount. However, for this purpose, both ends in the longitudinal direction of the elastic thin film 21 need to be bonded to the surface of the square tube shaft 25 with a double-sided adhesive tape 26 or the like as shown in FIGS. 5, 6, and 7.
[0024]
FIG. 6 is a cross-sectional view of a thin-film-enclosed buffering mechanism element according to the second aspect. Both ends in the width direction of the elastic thin film 21 are folded back toward the center line in the longitudinal direction. Further, an elastic cord 23, for example, a polyurethane fiber cord or a rubber cord, a metal thin wound multiple coil spring cord, or the like is selected at the width end side in the folded portion according to the packing object 40. It is not necessary to bond this embedded string to the elastic thin film 21.
[0025]
Due to the interior of the string, the shock resistance of the thin-film-capacity buffering mechanism element 20 in the transverse direction due to the folded width is larger than the folded film thickness effect and is increased to about 100 times in a wide range. In addition, the ability to enclose the packing object 40 is increased, but the familiarity of the surface of the elastic thin film 21 with the unevenness of the surface of the packing object 40 is reduced as the elastic string becomes higher. The shafts to be bonded and fixed to both ends in the longitudinal direction are the same as the previous means.
[0026]
FIG. 7 is a cross-sectional view of a thin-film-encapsulating cushioning element according to the third aspect of the present invention. Both ends in the width direction of the elastic thin film 21 are folded back toward the center line in the longitudinal direction. The wrapping band encloses the elastic band 24, for example, a rubber band, a multi-band shaped metal band or a polyurethane fiber band. The effect of this is somewhat inferior to that of the second means, but does not change much. Also, there is no great difference from the previous means regarding the shaft bar to be bonded and fixed to both ends in the longitudinal direction.
[0027]
