Description

【０００１】
【発明の属する技術分野】
本発明は、把手付き合成樹脂製容器及び容器用把手に関し、特に、リサイクル可能な把手付き合成樹脂製容器及び容器用把手に関する。
【０００２】
【背景技術及び発明が解決しようとする課題】
一般に、内容量の大きな合成樹脂製容器には、内容物を充填した際にかなり重量が重くなるため、内容物の注出時や持ち運びに便利なように把手が取り付けられている。
【０００３】
このような把手付き合成樹脂製容器としては、合成樹脂製容器の成形時に予め把手を一体化したものや、合成樹脂製容器と把手とを別体にして成形し、合成樹脂製容器に後付で把手を取り付けるようにしたものが知られている。
【０００４】
成形時に予め把手を一体化した把手付き合成樹脂製容器にあっては、把手と合成樹脂製容器とが分離できないように一体化されており、また、後付の把手付き合成樹脂製容器にあっては、一旦把手を取り付けた後で把手が合成樹脂製容器から外れることのないように、取り外し困難な状態で取り付けるようにしている。
【０００５】
これに対し、近年、合成樹脂製容器、特にポリエチレンテレフタレート（ＰＥＴ）製の容器が大量に市場に出回っていることから、ＰＥＴ製の容器のリサイクル活動が活発化してきている。
【０００６】
このようなＰＥＴ製の容器のリサイクルを行う場合、把手付き合成樹脂製容器において把手がＰＥＴ以外の材料を用いていると、把手を取り外して分別しなければならず、前述のような把手付き合成樹脂製容器にあっては、リサイクルが困難な状態となっている。
【０００７】
本発明の目的は、容器本体への取付が容易に行え、取付後には確実な取付状態を維持すると共に、取り外しも容易に行うことができてリサイクルに適した把手付き合成樹脂製容器及び容器用把手を提供することにある。
【０００８】
【課題を解決するための手段】
前記目的を達成するため、本発明の把手付き合成樹脂製容器は、側壁に内方に窪む把持用の凹部を有し、この凹部の上面及び下面の内方端部にそれぞれ把手と係合するための係合溝を有する合成樹脂製の容器本体と、
前記容器本体の係合溝に係合する係合突起部を有し、前記凹部に上下方向に沿って配設される把手とを備える把手付き合成樹脂製容器において、
前記把手は、上下方向に沿って伸びる把持部と、前記把持部より前記凹部の上下面に沿って位置すると共に前記係合溝対応位置に前記係合突起部を形成した上下取付板部とを有する把手本体と、
前記把手本体の側方から前記上下取付板部先端部間に挿入されて前記上下取付板部の先端部と係合し、前記上下取付板部が対向方向に撓むのを防止する固定部材とを有することを特徴とする。
【０００９】
本発明によれば、把手本体の上下取付板部に形成された係合突起部を容器本体の係合溝内に挿入して把手本体を容器本体に取り付けた状態としておき、この把手本体の側方から固定部材を上下取付板間に挿入して上下取付板部の先端部に係合させることで、容易に取り付けを行うことができる。
【００１０】
取り付け後は、固定部材が上下取付板部の対向方向への撓みを防止するため、上下取付板部に互いに近接する方向に力が加わっても、固定部材によって近接方向に撓んで係合突起部が係合溝から抜け出すのを防止でき、確実な取付状態を維持することができる。
【００１１】
取り外し時には、取り付け時と逆に、固定部材と上下取り付け板部の先端部との係合を解除して、固定部材を上下取付板部間から側方に抜き取った後、上下取付板部の係合突起部を容器本体の係合溝から抜き取ることにより、容易に取り外しができ、リサイクルに適したものとすることができる。
【００１２】
本発明においては、前記上下取付板部は、先端部に前記固定板の挿入方向に沿って肉抜き用の凹部を有し、前記固定部材は、前記肉抜き用の凹部内に挿入されることが好ましい。
【００１３】
このようにすることで、上下取付板の先端部に形成される肉抜き用の凹部を利用して、固定部材を挿入することで、複雑な構成とすることなく、係合による抜取方向への抜け出し防止に加え、固定部材の把持部側への抜け出しを防止することができる。
【００１４】
また本発明においては、前記固定部材は、前記上下取付板部の先端部間に配置されるプレート部の上下両側に差し込み方向先端側から後方側にかけて形成された上下スリットを介して弾性変形可能にされた係合爪付きの上下係合片を有することが好ましい。
【００１５】
このような構成とすることで、上下スリットによってプレートの上下両側に係合爪側を弾性変形可能にした上下係合片を容易に形成することができ、しかも、上下係合片の基部側は基部間に位置する連続したプレートの部分によって支持されるため、上下取付板部は対向方向の撓みが防止され確実に取付状態を維持することができる。
【００１６】
この場合、前記プレート部は、前記上下スリット間に差し込み方向後方側から先端側にかけて形成された中間スリットを有することが好ましい。
【００１７】
このようにすることで、中間スリットによってプレート部にスプリング効果を持たせることができ、上下係合片の撓み量を確保して、挿入時には挿入しやすく、また係合後には密着性を向上させて、確実な係合状態を得ることができる。
【００１８】
さらに本発明では、前記上下係合片の先端部は、前記上下取付板部の先端部より突出されていることが好ましい。
【００１９】
上下取付板部の先端部より突出した上下係合片の先端部を操作して上下取付眼部に対する上下係合片の係合解除を容易に行うことができる。
【００２０】
本発明の他の把手付き合成樹脂製容器によれば、側壁に内方に窪む把持用の凹部を有し、この凹部の上面及び下面の内方端部にそれぞれ把手と係合するための係合溝を有する合成樹脂製の容器本体と、
前記容器本体の係合溝に係合する係合突起部を有し、前記凹部に上下方向に沿って配設される把手とを備える把手付き合成樹脂製容器において、
前記把手は、上下方向に沿って伸びる把持部と、前記把持部より前記凹部の上下面に沿って位置すると共に前記係合溝対応位置に前記係合突起部を形成した上下取付板部とを有する把手本体と、
前記把手本体の側方から前記上下取付板部先端部間に挿入されて前記上下取付板の先端部と係合し、前記上下取付板部が対向方向に撓むのを防止する固定部材とを有し、
前記固定部材は、前記上下取付板部との係合状態を解除する操作部を有することを特徴とする。
【００２１】
本発明によれば、容器本体への取付が容易に行え、取付後には確実な取付状態を維持すると共に、取り外しも操作部を操作することで、容易に行うことができてリサイクルに適した把手を得ることがでる。
【００２２】
さらに、本発明の容器用把手は、側壁に内方に窪む把持用の凹部を有し、この凹部の上面及び下面の内方端部にそれぞれ把手と係合するための係合溝を有する合成樹脂製の容器本体に取り付けられる容器用把手において、
上下方向に沿って伸びる把持部と、前記把持部より前記凹部の上下面に沿って位置すると共に前記係合溝対応位置に前記係合突起部を形成した上下取付板部とを有する把手本体と、
前記把手本体の側方から前記上下取付板部先端部間に挿入されて前記上下取付板の先端部と係合し、前記上下取付板部が対向方向に撓むのを防止する固定部材とを有することを特徴とする。
【００２３】
本発明によれば、容器本体への取付が容易に行え、取付後には確実な取付状態を維持すると共に、取り外しも容易に行うことができてリサイクルに適した把手を得ることができる。
【００２４】
【発明の実施の形態】
以下、本発明の好適な実施例について、図面を参照して詳細に説明する。
【００２５】
図１〜図７は、本発明の一実施例に係る把手付き合成樹脂製容器を示す図である。
【００２６】
この把手付き合成樹脂製容器１０は、容器本体１２と、把手１４とから構成されている。
【００２７】
容器本体１２は、例えばポリエチレンテレフタレート（ＰＥＴ）等の合成樹脂を用いてブロー成形することにより、飲料水等の内容物を充填する容器の形状に形成されたもので、図３に示すように、上端の口部を含むネック部１６、ネック部１６から拡径しつつ下方に連なるショルダー部１８、ショルダー部１８から下方に延長された胴部を構成する側壁２０、側壁２０から縮径しつつ下方に連なるヒール部２２及びヒール部２２から連続して容器下端に位置する底部２４から構成される。
【００２８】
また、底部２４は、外周から中心にかけて容器内方へ向けて突出する凸部２６が形成された上底形状とされ、自立性が持たせられるようになっている。
【００２９】
また、側壁２０の上半部を構成する上側壁２８には、把持用の凹部３０が上側壁２８の周方向の一部分で、上下方向のほぼ全域にわたって形成された状態となっている。
【００３０】
この凹部３０は、上面３２、下面３４及び内壁面３６とから構成され、上面３２及び下面３４の略中央内方端部には、図１、図３及び図４にも示すように、それぞれ把手１４と係合するための係合溝３８、４０が上下方向に向けて形成された状態となっている。
【００３１】
内壁面３６は、図２の横断面図に示すように、中央部４２が窪んで両側部４４が斜めに傾斜した略台形状をなしており、両側部４４が上面３２及び下面３４の補強柱として機能し、上面３２及び下面３４に把手１４によって力が加わっても上面３２及び下面３４が変形しにくい状態としている。
【００３２】
また、この両側部４４が傾斜していることによって、例えば中央部４２の位置まで窪んでいる場合に比し、容器本体１２の内容量を増大させることができることとなる。
【００３３】
さらに、中央部４２は、把手１４の取付け対応位置にあり、上下の係合溝３８、４０間で上下方向にわたって断面略直線状の平坦面として形成されている。
【００３４】
このように、中央部４２を平坦面とすることにより、例えば内方に向かって湾曲している場合に比し、容器本体１２の内容量を増大させることができることとなる。
【００３５】
把手１４は、ポリプロピレン（ＰＰ）やポリエチレン（ＰＥ）等の合成樹脂を用いて射出成形により容器本体１２とは別に成形された後、容器本体１２の凹部３０に、その上下方向に沿って後付で配設されるもので、把手本体４６と、この把手本体４６に側方から差し込み固定される固定部材としての固定板４８とを別体に有している。
【００３６】
把手本体４６は、把持部５０と、上下取付板部５２、５４とを有している。
【００３７】
把持部５０は、手で把持するためのもので、容器本体１２の上側壁２８に形成した凹部３０との間に手指を挿入するための空間をおいてその上下方向ほぼ全体に渡って伸びるようになっている。
【００３８】
また、この把持部５０は、内容物を充填した容器本体１２を持ち上げた際に変形しないように補強リブ５６、５８等によって十分な剛性を持たせてある。
【００３９】
上下取付板部５２、５４は、把持部５０の上下両端部より凹部３０の上下面３２、３４に沿って容器本体の中心軸方向に伸びて位置すると共に、下取付板部５４は上取付板部５２よりも長く形成されていて把手本体４６の取り付け時に弾性変形可能にされている。
【００４０】
また、上下取付板部５２、５４は、それぞれの先端部６０、６２が互いに対向した状態で配置されている。
【００４１】
これら先端部６０、６２には、対向面側に固定板４８の挿入方向に沿って対向片６６に挟まれた肉抜き用の凹部６４が形成され、この凹部６４の奥側には、差し込み方向に沿うリブプレート６８が対向片６６の幅よりも狭い幅で設けられている。
【００４２】
さらに、これら上下取付板部５２、５４には、凹部３０の上下面３２、３４に形成した係合溝３８、４０と対応する先端部６０、６２側の位置に、各係合溝３８、４０と係合する係合突起部７０、７２がそれぞれ上下方向に突出した状態で形成されている。
【００４３】
固定板４８は、上下取付板部５２、５４の先端部６０、６２間に挿入係止されるもので、図５〜図７に示すように、プレート部７４と、上下係合片７６、７８を有している。
【００４４】
プレート部７４は、把手本体４６の幅と略同じ幅に設定され、上下取付板５２、５４の先端部６０、６２間に挿入された際に把手本体４６の幅と一致するようにされている。
【００４５】
上下係合片７６、７８は、プレート部７４の上下両側に差し込み方向先端側から後方側にかけて形成された上下スリット８０、８２を介して弾性変形可能に一体に形成されている。
【００４６】
これら上下係合片７６、７８の先端部には、それぞれ上下取付板部５２、５４の先端部６０、６２に設けたリブプレート６８の一端に係合する係合爪８４が上下方向に突出形成されている。
【００４７】
この係合爪８４は、プレート部７４の幅より長く形成され、固定板４８を上下取付板５２、５４の先端部６０、６２間に取り付けた状態で、先端部６０、６２より幅方向に突出して、係合状態を解除する際の操作部として用いられるようになっている。
【００４８】
また、上下係合片７６、７８の基端部には、それぞれ上下取付板部５２、５４の先端部６０、６２に設けたリブプレート６８の他端に係合する鉤形のフック８６が上下方向に突出形成されている。
【００４９】
次に、この把手１４の着脱状態について説明する。
【００５０】
まず、把手１４を容器本体１２に取り付ける場合には、図４に示すように、固定板４８を取り外した状態で、把手本体４６を手に持ち、上下取付板部５２、５４を容器本体１２側に向けた状態にして、凹部３０に挿入し、上取付板部５２の係合突起部７０を上面３２側の係合溝３８内に係合させる。
【００５１】
この状態で、上取付板部５２の係合突起部７０を中心にして、把持部５０の下方を凹部３０の内方側へ回転させると、下取付板部５４の係合突起部７２が凹部３０の下面３４に接触して、下取付板部５４が弾性変形しながら、下面３４に沿って移動し、下面３４の係合溝４０位置で下取付板部７２の復元力により係合溝７２内に係合されて、把手本体４６が容器本体１２に取り付けられて仮止め状態となる。
【００５２】
次に、図５に示すように、仮止め状態の把手本体４６に対して、固定板４８の係合爪８４を挿入方向に向けた状態で、把手本体４６の側方から上下取付板部５２、５４の先端部６０、６２間に固定板４８を挿入する。
【００５３】
この場合、固定板４８の上下係合片７６、７８が、上下取付板部５２、５４の先端部６０、６２に形成した凹部６４内に挿入されることとなる。
【００５４】
凹部６４内に挿入された上下係合片７６、７８は、上下スリット８０、８２の存在により、図６に示すように、係合爪６４がリブプレート６８に当接すると互いに近接する方向に弾性変形し、係合爪６４の通過を許す状態となる。
【００５５】
次いで、係合爪６４がリブプレート６８を通過した時点で、上下係合片７６、７８の復元力により、図７に示すように、係合爪６４がリブプレート６８と係合すると共に、フック８６もリブプレート６８と係合して、固定板４８の取り付けが完了すると同時に、把手１４の取り付けが容易に完了することとなる。
【００５６】
取り付け後は、固定板４８の係合爪８４がリブプレート６８の一端に係合し、かつ、フック８６がリブプレート６８の他端に係合しているため、固定板４８の挿入方向及び取出方向への動きが規制され、しかも、先端部６０、６２の対向片６６によって容器本体１２の中心軸と交差する方向での動きも規制されることとなるため、固定板４８は把手本体４６から外れることはなく確実な固定状態が得られる。
【００５７】
また、フック８６が各リブプレート６８の上下面と係合しているため、上下取付板部５２、５４の離反方向への動きが規制され、かつ、プレート部７４が上下スリット８０、８２がない部分で上下取付板部５２、５４の近接方向の動きが規制されるため、より確実に把手本体４６の取り付け状態が維持されることとなる。
【００５８】
把手１４の取り外し時には、図７に示すように、上下取付板部５２、５４の先端部６０、６２から幅方向に突出している固定板４８の係合爪８４を、図中矢印で示すように、近接方向に操作して、リブプレート６８との係合状態を解除し、固定板４８を取出方向に引き抜き、把手本体４６の下取付板部５４を上方に弾性変形させて係合溝３８、４０と係合突起部７０、７２との係合状態を解除することで容易に取り外しができ、ＰＥＴ製の容器本体１２とＰＰやＰＥ製の把手１４との分別が容易にでき、リサイクルに適したものとすることができる。
【００５９】
図８は、本発明の他の実施の形態にかかる固定板を示す図である。
【００６０】
この実施の形態では、前記実施の形態における固定板４８の状態に加えて、上下スリット８０、８２間略中央位置に、差し込み方向後方側から先端側にかけて中間スリット８８を形成することにより、プレート部７４にスプリング効果を持たせ、上下係合片７６、７８の撓み量を確保して、挿入時には挿入しやすく、また係合後には密着性を向上させて、確実な係合状態を得るようにしている。
【００６１】
他の構成及び作用は前記実施の形態と同様に付き、共通部分には共通の符号を付すにとどめ、説明を省略する。
【００６２】
図９は、本発明のさらに他の実施の形態にかかる固定板を示す図である。
【００６３】
この実施の形態では、図８の実施の形態における中間スリット８８に代えて、プレート部７４に中抜き部９０を形成することにより、図８の場合と同様の目的を達成できるようにしている。
【００６４】
他の構成及び作用は前記実施の形態と同様に付き、共通部分には共通の符号を付すにとどめ、説明を省略する。
【００６５】
図１０は、本発明のさらに他の実施の形態にかかる固定板を示す図である。
【００６６】
この実施の形態では、プレート部７４の幅を狭くして、上下スリット対応位置にプレート部７４が存在しないようにすることで、図８及び図９の場合と同様の目的を達成できるようにしている。
【００６７】
他の構成及び作用は前記実施の形態と同様に付き、共通部分には共通の符号を付すにとどめ、説明を省略する。
【００６８】
本発明は、前記実施例に限定されるものではなく、本発明の要旨の範囲内において種々の変形実施が可能である。
【００６９】
例えば、把手本体における上下取付板部の先端部に、固定板の挿入時に係合爪が入りやすくするための面取り部を形成することにより、固定板の取り付けを容易にすることも可能である。
【００７０】
また、例えば、上下取付板部の先端部に貫通孔を設け、固定板の係合爪をこの間通孔に通して係合させれば、上下左右の移動を簡単に制限できる。
【００７１】
さらに、容器の延伸ブロー成形工程において係合溝を形成する場合、金型に進退自在な突出部材を設け、ブロー成形途中において、引き込んでおいた突出部材を公知の駆動機構、例えば油圧シリンダやカム機構などを用いて金型面から突出駆動させることで確実に成形することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin container with a handle and a handle for a container, and more particularly to a recyclable synthetic resin container with a handle and a handle for a container.
[0002]
[Background Art and Problems to be Solved by the Invention]
In general, a container made of a synthetic resin having a large inner volume is considerably heavier when filled with contents, and therefore a handle is attached so that the contents can be poured out and carried easily.
[0003]
As such a synthetic resin container with a handle, a synthetic resin container in which a handle is integrated in advance at the time of molding, or a synthetic resin container and a handle are molded separately and attached to the synthetic resin container later. The one with the handle attached is known.
[0004]
In the case of a synthetic resin container with a handle in which a handle is integrated in advance, the handle and the synthetic resin container are integrated so that they cannot be separated from each other. In other words, once the handle is attached, the handle is attached in a state that is difficult to remove so that the handle is not detached from the synthetic resin container.
[0005]
On the other hand, in recent years, a large amount of synthetic resin containers, particularly polyethylene terephthalate (PET) containers, are on the market, and PET recycling activities have been activated.
[0006]
When recycling such PET-made containers, if the handle is made of a material other than PET in a synthetic resin container with a handle, the handle must be removed and separated. In the case of resin containers, recycling is difficult.
