Description

【０００１】
【発明の属する技術分野】
本発明は、ダンボール箱あるいは類似の箱の蓋を閉止して封緘する合成樹脂製閉止具に関する。
【０００２】
【従来の技術】
紙製のダンボール箱や合成樹脂製の軽量な箱は、野菜や花、衣類等の各種の軽量な商品、家電製品等を収容する箱として、あるいは転宅の際の各種の家財等の保管箱として多く使用されている。
これらの用途に使用される箱の蓋を閉止する方法は、野菜や花のように１回の輸送に使用する箱の場合は、粘着テープや金属製閉止具（ホッチキス）で閉止する方法が普通に使用されている。
【０００３】
また、家電製品のような商品の紹介、確認、説明等でたびたび開封するような商品の場合は、粘着テープや金属製閉止具のように開封の困難性や怪我の危険性を回避する意味で、確実に閉止しながら開封が容易で安全な合成樹脂製閉止具が特公昭５７−５７３２６号公報で提案されいてる。
一方、スポーツ用品等の倉庫から出荷される衣類等の商品を販売店に輸送する場合や無店舗販売の商品の輸送には通い箱が使用されている。この通い箱は、商品やその他の荷物を出発場所から到達場所まで確実に配送する必要があることから、蓋体の開閉状態を確認できる封緘具を使用して商品等の出所とその商品等の品質や数量を保証する必要がある。また、通い箱は簡単に開封でき、店頭に商品を陳列する時間が短縮でき、しかもこの通い箱は繰り返し使用できるものが望ましい。
【０００４】
【発明が解決すべき課題】
前記公報に記載された合成樹脂製閉止具は、家電製品等の商品を収容した箱の蓋の閉止に使用されるもので、確実に閉止することができる上に、利用者自身が簡単に開くことができるという点において優れている。
しかし、この閉止具は箱の２枚以上の蓋を爪で破って穴を明けながら蓋の裏側までその爪を進入させた状態で蓋を支持固定するものであり、家電製品のように緩衝部材が使用されて傷が付きにくい商品の包装には適している。しかし、衣類のような柔軟で破損し易い商品や所定の区間だけ荷物を輸送するための箱や転居等に使用する箱のように繰り返し使用する箱の蓋の閉止には適してない。また、前記のように爪が商品を破損し易いという問題がある上に封緘具としての機能が全くないものである。
【０００５】
本発明は、前記箱の蓋体の閉止具の欠点を解消し、蓋体を損傷せず、箱を複数回使用することができ、更に商品を損傷せず、封緘機能を持つ合成樹脂製の閉止具を提供するものである。特に通信販売や無店舗販売等の配送回数の多い配送箱の閉止具に適している。
【０００６】
【課題を解決するための手段】
前記目的を達成するための本発明に係る合成樹脂で一体成型した箱の閉止具は次のように構成されている。
１）細長い板状の本体２と、該本体２に沿って２個の室２ｂ，２ｃが形成され、前記本体２の両端部に位置する前記室２ｂ，２ｃの端部に、それぞれ基体部５を形成し、該基体部５を介して爪体３，３ａを揺動可能に支持し、該爪体３，３ａは前記基体部５側に肉厚部９を有すると共に先端側に円弧状の爪７を突出形成しており、前記基体部５は、複数の切断可能な連結部４によって前記本体２に連結されており、前記爪体３，３ａは前記本体２より起立可能であり、更に、側面視で前記本体２と前記爪体３，３ａが略コ字状に起立した状態で、被閉止物である箱１６の蓋１６ａに開孔された孔１７を閉止すると共に、前記爪７が前記蓋１６ａの裏面に弾力を持って押圧する如く構成され、合成樹脂の一体成形品で構成されている。
【０００７】
２）前記基体部５の縁部と本体２との間は複数本の連結部４を介して接続され、更に、ヒンジ部５ａを介して爪体３，３ａを揺動可能に支持している。
３）爪体３，３ａは、複数の小断面の切断可能な連結部４を介して連結された基体部５と、この基体部５にヒンジ５ａを介して連結されて回動部６と、この回動部６の先端に突出した爪７を有し、回動部６の両面に形成された肉厚部９，９ａによって蓋１６ａに開口した穴１７に嵌合するガイド部とすると共に、連結部４を切断するに際して、肉厚部９ａの端部９ｂを基体部５の肉厚部５ｂに当接させてこの連結部４を切断し易く構成されている。
【０００８】
なお、前記肉厚部９，９ａは回動部６の両面に形成（回動部６の一部の断面が十字形になる）するのが好ましいが、実施の形態に説明するように一方に肉厚部９を省略した形（断面かＴ字形）のものでも使用することができる。回動部６の主要部分は２本の棒状に形成されてこれらの棒状部分の間に窓８が形成されているが、この窓８は爪７等を形成するための金型を通す道であると共に回動部６に柔軟性を与える意味もある。
【０００９】
４）連結部４は薄いシート状に形成されている。しかし、連結部４を薄いシートに形成すると破断強度の調整が困難な場合もあるので、比較的厚い連結部４を形成し、これにＶ型断面の薄状の弱い部分を形成することによって正確に破断強度を設定することができる。また、Ｖ形断面の溝状に代えて、あるいはこれと併用して点線状に窪みないしは穴を開けることもできる。
【００１０】
５）閉止具１を平行して配列した状態で、閉止具１同士を連結部材１５で連結した集合体とすることができる。
【００１２】
【発明の実施の形態】
次に図面を参照して本発明の実施の形態を説明する。
図１は閉止具の平面図、図２は同背面図、図３は一部を切断した側面図、第４図は一部を切断した横断面図である。
本発明に係る各種箱の閉止具は、ナイロンやポリプロピレンの如き柔軟性のある工業用の樹脂で成形したものであって、閉止するダンボール箱等の蓋に大きな損傷を与えることなく閉止し、更に封緘機能を与えるものである。
【００１３】
本発明に係る閉止具１は、細長い枠状の本体２の内部に爪体３，３ａを中央部に向かい合わせに配置し、この爪体３，３ａの端部の基体部５を切断可能な、複数の連結部４で前記本体２に設けており、ダンボール箱や合成樹脂製箱等の箱状物の蓋ないしは閉止部材を閉止し固定する際に、この爪体３，３ａを引起して蓋に係合して閉止するものである。
【００１４】
本体２は細長い枠状あるいは額縁状に形成され、中央部を連結体２ａで補強しながら２つの室２ｂ，２ｃに区分している。そしてそれぞれの室２ｂ，２ｃに爪体３，３ａを配置し、基体部５を外側にして３個の連結部４で固定している。
前記連結部４は閉止具１に封緘機能を与えるための部材であって、この実施の形態においては本体２側を太く、基体５側を縮小した三角形に形成し、その先端の基体部５と連結されている部分は爪体３，３ａを強く引張った際に破断するように構成されている。
【００１５】
前記肉厚に形成した基体部５の一方に肉薄のヒンジ部５ａが設けられ、このヒンジ部５ａを介して回動部６が支持されている。この回動部６は本体２より折れ曲がって箱の蓋側に挿入される部分で、その先端にクワ形の爪７（あるいは係合部）が設けられている。この爪７の下方に窓８が開口されて回動部６の主要部分は２本の棒状に形成されてこの回動部６に柔軟性を与えている。そして前記回動部６の先端に爪７が支持されており、この爪７の後部を延長して係合部７ａが設けられており、爪７は全体としてつるはし状に形成されている。なお、前記窓８は、爪７を成形する金型部材の通り道と、爪体３，３ａを構成する回動部６の一部を曲がり易いようにする効果も与えている。
【００１６】
前記回転部６を支持するヒンジ部５ａに隣接する部分は、図１の平面図に示すようにＴ字形の肉厚部９が、図２の裏面には一文字状の肉厚部９ａがそれぞれ形成されており、図４に示すように回動部６の根本部分は十字形断面に形成されて爪体３，３ａを補強している。また、前記Ｔ字形の肉厚部９の部分９ｃは、閉止する箱の蓋に設けた穴の入口部分を閉止する蓋としての機能を持っている。
【００１７】
図３及び図４に示すように回動部６の根元部分の両側に肉厚部９，９ａが形成されているが、表側は裏側より薄く形成されており、その厚さは爪７の突出幅の約１／３程度で、この爪７が箱の蓋の裏側に引掛かる際の強さを減じないようにして確実に係合するようにしている。
一方、裏側の肉厚部９ａは表側に形成した肉厚部９に比較してかなり厚く形成し、これの角部９ｂを基体部５の肉厚部５ｂに当接するストッパーと、穴に当接するガイドとしての機能を有するようにしている。そして上面に形成した肉厚部９も後述する箱の蓋に開けた穴に挿入されるガイドとして機能するようにしており、この回動部６が蓋に開けた穴に挿入された場合に大きなガタ付きがないようにしている。
【００１８】
図３において符号Ｆは閉止具１の表面を、また、符号Ｂは裏面をそれぞれ示しているが、表面Ｆの周囲に面取り１１を行ない、更に裏面Ｂの中間部の肉を削って指掛け部１２を形成している。
閉止具１は射出成形によって製造されるが、図５に示すように隣接する閉止具１同志を連結体１５で連結した状態で平板状の集合閉止体Ｎに成形し、この集合閉止体Ｎを取付装置（詳細は図示せず）に装填し、レバーを操作すると連結体１５を切断して１個づつ閉止具１を分離し、そして図１１に示すように押圧体２０が矢印Ｄのように前進してその先端の階段状に形成した押圧部２１が肉厚部９を押圧し、図１２に示すように爪体３，３ａを本体２に対して角状に起立させる。
【００１９】
この状態になると取付装置の先端部に１個の閉止具１が、その爪体３，３ａを前方にあたかも２本の角のように立てた状態に保持されることになり、このように立った２本の爪体３，３ａをダンボール箱のような箱の蓋に開けた２個の穴に同時に挿入押圧して取付けることになる。従って、爪体３，３ａの先端に設けた爪７は蓋の裏側に抜けた状態でその先端７ａと蓋の裏側との間に僅かな隙間がある寸法にしておく（図９）。
【００２０】
図６は集合閉止体Ｎから外した１個の閉止具１の斜視図を示しており、ダンボール箱等の箱１６の蓋１６ａの閉止等に使用する際は、図１１及び図１２で説明したように取付装置を操作して本体２に対してヒンジ部５ａを支点として回動部６を矢印Ａのように押圧し、図７に示すように爪体３，３ａを矢印Ｂのように回転させながら下方に押出して角状に突出させる。そしてダンボール箱等の箱１６の蓋１６ａ等にあけた穴１７に、前記爪体３，３ａの爪７を矢印Ｃのように強制的に挿入する。
【００２１】
図９に示すように、この爪７の突出幅は肉厚部９より大きく、穴１７より外方に伸びて蓋１６ａの裏面に引掛けることができる寸法に形成してあるので、爪体３，３ａを穴１７内に強制的に蓋１６ａの裏面まで押込むと爪７の先端７ａは穴１７の周囲を越えて係止されることになる。
この図９の状態では爪７の先端７ａと蓋１６ａの裏側との間に僅かな間隙ｄが形成されている。また、この状態になると基体部５の肉厚部５ａに爪体３，３ａに形成した肉厚部９ａの角部９ｂが基体部５の肉厚部５ａの裏側に当接して本体２に直交した状態に爪体３，３ａの姿勢が保持されることになる。この閉止具１を箱１６に取付けた状態では、Ｔ形の肉厚部９の部分９ｃと基体部５で穴１７を閉止しており、蓋１６ａの裏側に位置している爪７を操作して閉止状態を解除することはできない。
【００２２】
このように閉止具１を箱１６に取付けた状態は図８及び図９のようになり、箱１６の蓋１６ａを確実に閉止すると共に、無理に引張ると連結部４が破壊される「封緘効果」を発揮することになる。
もし、このように取付けられた閉止具１を箱１６より外して内容物を取出したり、内部を点検しようとすると、本体２より爪体３，３ａが連結部４より切断されて封緘が破壊されたことになり、例えばこの箱１６内に重要な物が入れられていた場合に、第三者がこの封緘を故意に破壊した時は、もはやその内容物を保証しないことになる。
【００２３】
本発明に係る閉止具１を箱１６から外す場合は、図８及び図２に示す指掛部１２に指あるいは外し工具を掛けて図１０に矢印Ｄで示すように本体２を上方に曲がるように引上げると、爪７の先端が蓋体１６ａの裏面に引掛って抵抗する。更に本体２を引上げると、この本体２と基体部５とを接続している強度の弱い連結部４が、ねじ切り効果でその張力に耐えられなくなって破断されて穴１７内に爪体３，３ａを残すか、あるいは箱１６の中に脱落させ、蓋１６ａを自由にして解放できる。
【００２４】
前記連結部４は、図１０に示すように爪体３ａの爪７が蓋１６ａの裏側に係止されて抜けに対して抵抗する。そして肉厚部９ａの角部９ｂが基体部５の肉厚部５ｂを支持する状態となり、基体部５に接続されている連結部４に大きな剪断力あるいは張力が作用して封緘部分が破壊されて解放されることになる。
図１３（Ａ）〜（Ｃ）は開封の順序を示しており、（Ａ）図は閉止、即ち封緘状態、（Ｂ）は本体２を矢印Ｄのように引上げた状態で、爪体３ａの爪７の先が蓋１６ａの裏側に作用して箱１６より閉止具１が外れるのに抵抗する。更に本体２を図（Ｃ）の矢印Ｄ′のように引上げると爪７と、この爪７の反対側に突出している係止部７ｂが穴１７の周囲に引掛かる。この状態では爪体３ａは穴１７より若干突出するが、基体部５の肉厚部５ｂと角部９ｂが当接して連結部４に剪断力を発生し、遂にこの連結部４が破断して本体２と爪体３，３ａとが分離し、封緘が解除されて蓋１６ａを解放し、内容物を取出すことができる。
【００２５】
なお、連結部４は、この実施の形態においては図１及び図２に示したように小面積で切断するように形成してあるが、これに限定するものではなく、これの代わりに薄いシート状に形成し、更に比較的厚い部分であってもＶ字形断面の破断溝を形成しておき、図１３のように本体２に大きな力が引張力が作用した時にこのシート状の連結部４が破断するように形成することもできる。
【００２６】
図５，図１４〜図１６は別の実施の形態の閉止具１を示しており、この閉止具１は回動部６の一方の表面に箱１６の蓋１６ａに設けた穴１７を閉止する蓋体となる部分９ｃを形成した構造を示している。
図１７（Ａ）〜（Ｃ）は爪体３，３ａの先端の爪７の形状を変更した例を示しており、先に図１３（Ａ）〜（Ｃ）を参照して説明した閉止具１の爪体３，３ａと対比して、爪７の反対側に伸びる先端部７ａを省略した形のものである。この爪体３，３ａの場合は、回動部６が比較的曲がりにくいような強度にして専ら爪７で蓋１６ａの裏面を保持するようにしておくと良い。
【００２７】
なお、本発明に係る閉止具１は、取付装置を使用した場合に取付け易いことから、搬送途中での閉止具１を交換することは比較的困難であり、補助封緘効果も兼ねている。
【００２８】
【発明の効果】
本発明に係る箱の閉止具１は、枠形の本体２の内部に形成した室２ｂ，２ｃに爪体３，３ａを対向して配置してその基体部５を前記本体２の両端部に固定しており、前記爪体３，３ａは前記基体部５が切断可能な連結部４を介して本体２の両端部で固定され、この爪体３，３ａを構成する回動体６の先端に被閉止体に係合する爪７を突出した構造に合成樹脂で一体成形している。
【００２９】
従って、箱１６の蓋１６ａに開けた穴１７を利用して閉止具１を簡単に押圧して取付け、箱１６に爪７を確実に係止して蓋１６ａの閉止と封緘効果を発揮することができる。
そして本体２を強く引張った場合は、爪体３，３ａと本体２とを連結している連結部４が破壊されることになり、蓋１６ａを解放したか否かを明確に確認することができる。
【００３０】
また、前記のように閉止具１を構成することによって図５に示すように多数の閉止具１を連結した集合閉止体Ｎを製造することができ、このような形状の集合閉止体Ｎとすることによって取付装置に装填して自動的に押出して箱に取付けることができる。

When it is loaded into an attachment device (not shown in detail) and the lever is operated, the connecting body 15 is cut to separate the closing tool 1 one by one, and the pressing body 20 is as shown by an arrow D as shown in FIG. The pressing portion 21 that is advanced and formed in a stepped shape at the tip presses the thick portion 9 and raises the claw bodies 3 and 3a in a square shape with respect to the main body 2 as shown in FIG.
[0019]
In this state, one closing tool 1 is held at the tip of the mounting device in a state where the claws 3 and 3a are stood up as if they were two corners. Two claw bodies 3 and 3a are simultaneously inserted and pressed into two holes formed in a lid of a box such as a cardboard box. Therefore, the claw 7 provided at the front end of the claw bodies 3 and 3a is dimensioned so that there is a slight gap between the front end 7a and the back side of the lid in a state where the claw 7 is detached from the back side of the lid (FIG. 9).
[0020]
FIG. 6 shows a perspective view of one closing tool 1 removed from the collective closing body N. When used for closing the lid 16a of a box 16 such as a cardboard box, it has been described with reference to FIGS. Thus, the mounting device is operated to press the rotating portion 6 as indicated by an arrow A with respect to the main body 2 using the hinge portion 5a as a fulcrum, and the claws 3 and 3a are rotated as indicated by an arrow B as shown in FIG. While pushing down, it is extruded downward to project into a square shape. And the nail | claw 7 of the said nail | claw bodies 3 and 3a is forcibly inserted like the arrow C in the hole 17 drilled in the lid | cover 16a etc. of the boxes 16, such as a cardboard box.
[0021]
As shown in FIG. 9, the protruding width of the claw 7 is larger than the thick portion 9, and has a dimension that extends outward from the hole 17 and can be hooked on the back surface of the lid 16 a. , 3a is forced into the hole 17 to the back surface of the lid 16a, and the tip 7a of the claw 7 is locked beyond the periphery of the hole 17.
9, a slight gap d is formed between the tip 7a of the claw 7 and the back side of the lid 16a. In this state, the corner portion 9b of the thick portion 9a formed on the claws 3 and 3a contacts the thick portion 5a of the base portion 5 and contacts the back side of the thick portion 5a of the base portion 5 so as to be orthogonal to the main body 2. In this state, the postures of the nail bodies 3 and 3a are held. In a state in which the closing tool 1 is attached to the box 16, the hole 17 is closed by the portion 9c of the T-shaped thick portion 9 and the base portion 5, and the nail 7 located on the back side of the lid 16a is operated. The closed state cannot be released.
[0022]
The state in which the closing tool 1 is attached to the box 16 is as shown in FIGS. 8 and 9, and the lid 16 a of the box 16 is securely closed and the connecting portion 4 is broken when forcibly pulled. Will be demonstrated.
If the closure 1 attached in this way is removed from the box 16 and the contents are taken out or the inside is to be inspected, the claw bodies 3 and 3a are cut from the connecting part 4 from the main body 2 and the seal is destroyed. For example, when an important item is put in the box 16 and the third party intentionally destroys the seal, the contents are no longer guaranteed.
[0023]
When the closure 1 according to the present invention is removed from the box 16, the finger 2 or the removal tool is hung on the finger hook 12 shown in FIGS. 8 and 2, and the main body 2 is bent upward as shown by the arrow D in FIG. When pulled up, the tip of the claw 7 catches on the back surface of the lid 16a and resists. When the main body 2 is further pulled up, the weakly connecting portion 4 connecting the main body 2 and the base body portion 5 is not able to withstand the tension due to the threading effect, and is broken, so that the nail body 3 is inserted into the hole 17. 3a can be left or dropped into the box 16 to free the lid 16a.
[0024]
As shown in FIG. 10, the connecting portion 4 is configured such that the claw 7 of the claw body 3 a is locked to the back side of the lid 16 a and resists disconnection. Then, the corner 9b of the thick part 9a supports the thick part 5b of the base part 5, and a large shearing force or tension acts on the connecting part 4 connected to the base part 5 to destroy the sealed part. Will be released.
13A to 13C show the order of opening, FIG. 13A shows a closed state, that is, a sealed state, and FIG. 13B shows a state in which the main body 2 is pulled up as shown by an arrow D, The tip of the claw 7 acts on the back side of the lid 16 a to resist the removal of the closing tool 1 from the box 16. Further, when the main body 2 is pulled up as indicated by an arrow D ′ in FIG. (C), the claw 7 and the engaging portion 7 b protruding on the opposite side of the claw 7 are hooked around the hole 17. In this state, the claw body 3a slightly protrudes from the hole 17, but the thick portion 5b and the corner portion 9b of the base portion 5 come into contact with each other to generate a shearing force on the connecting portion 4, and finally the connecting portion 4 breaks. The main body 2 and the claws 3 and 3a are separated, the sealing is released, the lid 16a is released, and the contents can be taken out.
[0025]
In this embodiment, the connecting portion 4 is formed so as to be cut with a small area as shown in FIGS. 1 and 2, but the present invention is not limited to this, and a thin sheet is used instead. Even if it is a relatively thick portion, a V-shaped cross-section fracture groove is formed, and when a large force is applied to the main body 2 as shown in FIG. Can also be formed to break.
[0026]
5 and 14 to 16 show a closing tool 1 according to another embodiment. This closing tool 1 closes a hole 17 provided in a lid 16a of a box 16 on one surface of a rotating portion 6. FIG. The structure which formed the part 9c used as a cover body is shown.
17A to 17C show an example in which the shape of the claw 7 at the tip of the claw bodies 3 and 3a is changed, and the closure described above with reference to FIGS. 13A to 13C In contrast to the first claw bodies 3 and 3a, the tip 7a extending to the opposite side of the claw 7 is omitted. In the case of the claw bodies 3 and 3a, it is preferable that the rotation portion 6 has a strength that is relatively difficult to bend, and the claw 7 holds the back surface of the lid 16a exclusively.
[0027]
In addition, since the closing tool 1 which concerns on this invention is easy to attach when using an attachment apparatus, it is comparatively difficult to replace the closing tool 1 in the middle of conveyance, and it also serves as an auxiliary sealing effect.
[0028]
【The invention's effect】
The box closing tool 1 according to the present invention has claws 3 and 3a facing each other in chambers 2b and 2c formed inside a frame-shaped main body 2, and base portions 5 at both ends of the main body 2, respectively. The claw bodies 3 and 3a are fixed at both end portions of the main body 2 via connecting portions 4 that can cut the base body portion 5, and are attached to the distal ends of the rotating bodies 6 constituting the claw bodies 3 and 3a. The claw 7 that engages with the body to be closed is integrally formed with a synthetic resin in a protruding structure.
[0029]
Therefore, the closing tool 1 is simply pressed and attached using the hole 17 formed in the lid 16a of the box 16, and the claw 7 is securely locked to the box 16 to exert the effect of closing and sealing the lid 16a. Can do.
And when the main body 2 is pulled strongly, the connecting portion 4 connecting the claws 3 and 3a and the main body 2 will be destroyed, and it can be clearly confirmed whether or not the lid 16a has been released. it can.
