Description

【０００１】
【発明の属する技術分野】
本発明は、手提げ部材が設けられた発泡合成樹脂製の容器、特に、必要に応じて手提げ部材を容器に着脱することが可能な手提げ容器に関するものである。
【０００２】
【従来の技術】
発泡合成樹脂製の容器は断熱性が高く、氷や保冷剤、ドライアイス等を投入しておくことにより長時間に渡り保冷状態を維持することができるので、冷蔵を必要とする海産物等の生鮮食品や、アイスクリームのような保冷食品を運搬する際の容器として用いられている。さらに、耐水性や衝撃吸収性にも優れ、且つ軽量であることから、医薬品や精密機器等の運搬にも利用されている。
【０００３】
このような発泡合成樹脂製の容器には、業務用の大型のものの他、店頭販売された土産品等を購買者が自宅に持ち帰えるまでの保冷容器として、比較的容量の小さい小型のものがあるが、購買者等が手に提げて持ち運ぶことができるような品物を収容する容器には、持ち運びの便宜のために手提げ紐を設けたものがある。
【０００４】
図１５は、手提げ紐を設けた従来の発泡合成樹脂製の容器の一例を示すものであるが、従来の手提げ容器８０は、発泡合成樹脂製の本体８１及び蓋体８２を備えたものであって、該本体８１の対向位置にある２つの側壁から外方へ向けて突出部８３が形成され、各突出部８３に、突出部８３を上下方向に貫通する２つの貫通孔８４が所定間隔で穿たれ、該２つの貫通孔８４に１本の手提げ紐８５が挿通されて環状に結わえられてなるものである。これにより、２本の手提げ紐８５を片手で併せ持って、又は手提げ紐８５に腕を通し肩から提げるようにして、所望の品物が収容された手提げ容器８０を持ち運ぶことができ、便利である。
【０００５】
【発明が解決しようとする課題】
前記突出部８３は、貫通孔８４を穿つに十分な幅と、所望の品物を収容した手提げ容器８０の荷重を支持するに十分な強度とを考慮した形状及び大きさとされているが、当該手提げ容器８０を量産して保存、運搬等するために、多数の手提げ容器８０を数列に分けて積み上げて梱包すると、積み上げられた手提げ容器８０間に前記突出部８３の分だけ空間が生じるので、梱包の効率が悪くなる。同様に、運搬車の荷台に積載する場合にも積載効率が悪くなり、その結果、倉庫費用や運搬費用が高くなるという問題がある。さらに、保存、運搬等の状態では、手提げ紐８５が弛んで、手提げ容器８０の側壁から垂れ下がり、梱包作業や運搬作業に支障を与えたり、見栄えが悪いという問題もある。
【０００６】
一方、図１６は、別形態の従来の発泡合成樹脂製の容器を示すものであるが、該手提げ容器９０は、発泡合成樹脂製の本体９１及び蓋体９２を備えたものであって、該本体９１の側壁から底面、さらに対向する側壁に渡って凹溝９３を並列して設られており、該凹溝９３に環状の手提げ紐９４が挿入された後、凹溝９３の側壁部分に紐固定部材９５を嵌着することにより、本体９１に手提げ紐９４が固定されたものである。本手提げ容器９０は、前記手提げ容器８０のように側壁に突出部を有しないので、前述したように梱包効率や積載効率が低下することはないという利点はあるが、手提げ紐９４が垂れ下がるという問題は残る。また、本体９１や蓋体９２の他に、固定部材９５を別途成形加工する必要があり、コストが高くなるという問題が生じる。
【０００７】
また、特開２００２−１０４４２６号公報に提案されているように、前記本体９１の底面に、弛んだ手提げ紐９５を収納するための紐収納溝を設け、必要に応じて該紐収納溝から手提げ紐９５を引き出して使用する手提げ容器が提案されているが、該手提げ容器においても前記手提げ容器９０と同様に固定部材が必要となる。また、手提げ紐のように一定形状を維持することができない部材の取付作業は機械的に行うことが難しいので、手作業によって取り付けることとなるが、手提げ紐を結わえたり、紐収納溝に収納する作業は手間がかかり、製造コストも増える。
【０００８】
本発明は、これらの問題に鑑みてなされたものであり、従来の手提げ容器と同様に、断熱性、耐水性、衝撃吸収性に優れた軽量な容器であって、梱包効率、積載効率の低下や作業への支障が生じず、また、部品点数の増加や手提げ紐の取付作業が煩雑となる等、コストを増大させることのない手提げ容器を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明に係る手提げ容器は、発泡合成樹脂製の容器に手提げ部材が着脱可能に設けられてなる手提げ容器であって、前記容器の側壁の外面から略厚み方向へ凹欠され、且つ、その所定深さから側壁の略長さ方向へ凹欠されたスリット溝が、該側壁の縁部から中央部近傍へ延設され、前記手提げ部材の端部に、前記スリット溝と略同形状の嵌装部が形成されたものである。前記手提げ部材の嵌装部をスリット溝に嵌めることにより、容器の側壁に手提げ部材が装着されて、該容器を横転させた状態で手提げ部材を握って容器を持ち運ぶことができ、梱包等の際には、手提げ部材を取り外した状態で容器内等に収容しておくことにより、容器の側壁から突出する部材がなく、梱包効率や積載効率を低下させることがない。
【００１０】
前記容器に用いられる発泡合成樹脂としては、例えばポリスチレン等のスチレン系樹脂、ポリエチレン、ポリプロピレン等のオレフィン系樹脂等があり、成形加工性やコストから発泡ポリスチレンを用いることが望ましい。また、発泡合成樹脂の成形方法として、例えば発泡ポリスチレンを用いる場合には、金型を用いた型内発泡成形等を採用することができる。
【００１１】
また、前記容器は、本体と蓋体とを具備してなるものであって、該本体の上端面及び蓋体の下端面には嵌合凸条又は嵌合凹条が夫々形成され、該嵌合凸条及び嵌合凹条の各側面には係止凸部又は係止凹部が夫々形成され、前記嵌合凸条と嵌合凹条とが嵌合されるとともに前記係止凸部と係止凹部が係合することにより、蓋体で本体が封止されるものである。これにより、本体と蓋体との嵌合が強固なものとなり、容器内に所望の品物を収納して持ち運ぶ際に容器を横転状態としても、蓋体が本体から外れることがない。
【００１２】
前記スリット溝を設けるべき側壁は任意であり、例えば立方体状の容器であれば、長尺側の側壁でも短尺側の側壁でもよい。また、長尺側の側壁及び短尺側の側壁にスリット溝を夫々設けて、いずれのスリット溝に手提げ部材を嵌装するかは、使用者の便によって適宜選択可能としてもよい。
【００１３】
また、容器の側壁の外面から略厚み方向へ凹欠され、且つ、その所定深さから側壁の略長さ方向へ凹欠されたスリット溝とは、例えば、その断面がＬ字形、鉤形、Ｔ字形のようなものを含むものであるが、手提げ部材の着脱の便宜や、容器の荷重の支持効率を考慮すれば、前記スリット溝、及び手提げ部材の端部を略Ｔ字形とすることが好適である。また、スリット溝は容器の側壁の縁部から中央部近傍に延設されるものであるが、該縁部は、容器の上端面、底面、又は当該側壁と隣接する別の側壁の外面のいずれであってもよい。一方、該中央部近傍とは、側壁の中央部を含む周辺一体をいう（以下、単に中央部と記載することがある。）
【００１４】
また、前記スリット溝は、前記側壁の縁部から中央部近傍へ向かって縮幅されたものであることが好ましい。これにより、スリット溝に手提げ部材を嵌める際に中央部へ圧入することとなって、スリット溝の内面と手提げ部材の嵌装部の表面とが密接し、その接触面に生じる摩擦力により手提げ部材が側壁中央近傍の嵌装位置で固定され、持ち運び時に縁部方向へスライドすることがない。ここで、スリット溝の縮幅とは、凹欠の幅が縮小されることをいい、例えばＴ字形であれば、Ｔ字形が均等に縮小されたものや、Ｔ字形の任意の部位の凹欠幅が縮小されることをいう。
【００１５】
また、容器の側壁の厚みが薄く、容器の重量を支持するに十分な強度を有しない場合には、容器の側壁に、前記スリット溝を形成すべき位置の周辺を厚み方向に膨出させてなる補強部を設けることにより、手提げに必要な強度を容器の側壁に付与することができる。
【００１６】
また、前記手提げ部材は可撓性を有するものであることが好ましい。これにより、例えばスリット溝の位置や間隔に対して自由度が増して手提げ部材の嵌装が容易となり、さらに、手提げ状態で持ち運ぶ際に、容器等の荷重により手提げ部材が適度に撓って持ち易さも向上される。このような可撓性を有する素材としては、例えばポリプロピレン、ポリエチレン、ポリスチレン、ポリエステル、塩化ビニル等の合成樹脂や、パルプをプレス加工したもの等があるが、加工の容易さやコスト、耐水性等の性能から合成樹脂が好適である。
【００１７】
【発明の実施の形態】
以下、本発明の実施の形態に係る手提げ容器について図を用いて具体的に説明する。なお、本実施の形態は一例であり、本発明が実施の形態に限定されるものではないことは当然である。
【００１８】
図１は、本発明の実施の形態に係る手提げ容器の分解斜視図である。図に示すように、本手提げ容器１００は、上部が開口した中空直方体の容器本体１０と、該容器本体１０の開口を封止する蓋体２０と、容器本体１０に着脱自在な手提げ部材３０とを具備してなるものである。
【００１９】
前記容器本体１０及び蓋体２０は、発泡ポリスチレンの予備発泡ビーズを所定の金型内で夫々発泡成形してなる発泡合成樹脂製のものであり、容器本体１０の上端面に嵌合凸条１１が環状に形成され、一方、蓋体２０の下端面に嵌合凹条２１が環状に形成されており、該嵌合凸条１１と嵌合凹条２１とが嵌合することにより容器本体１０が蓋体２０で封止されるものとなっている。
【００２０】
図２は前記嵌合構造の一例を示す部分断面図であるが、容器本体１０の上端面に形成された嵌合凸条１１は、容器本体１０の内壁面に沿って上端面から垂直方向に突出しており、その幅Ｗ１は容器本体１０の側壁の厚みＷ０の略１／２程度である。また、嵌合凸条１１の高さＨ１は、蓋体２０の水平方向のズレを規制するに十分な高さであって、蓋体２０の厚みを考慮して適宜設定する。さらに、該嵌合凸条１１の外側面には主係止凸部１２が、内側面には補助係止凹部１３が形成されている。主係止凸部１２は、嵌合凸条１１の外側面の上部から外側方へドーム状に膨出したものであり、補助係止凹部１３は、嵌合凸条１１の内側面の中央部付近から外側方、即ち主係止凸部１２の膨出方向と同方向へ凹陥したものである。補助係止凹部１３は主係止凸部１２より小さなものであり、具体的には、主係止凸部１２の膨出方向の高さＨ２に対して、補助係止凹部１３の凹陥方向の高さＨ３を略１／３程度とすれば、十分な係止力を発揮でき、成形金型から抜き易いものとなるので好ましい。
【００２１】
一方、蓋体２０の下端面に形成された嵌合凹条２１は、前記嵌合凸条１１と対応する位置に凹設されており、その幅や高さも嵌合凸条１１と合致するように設定されている。該嵌合凹条２１の外側面及び内側面には、前記主係止凸部１２及び補助係止凹部１３と対応する主係止凹部２２及び補助係止凸部２３が夫々形成されている。主係止凹部２２及び補助係止凸部２３の形状は、夫々前記主係止凸部１２及び補助係止凹部１３と合致するものであり、主係止凹部２２は嵌合凹条２１の外側面の上部から外側方へドーム状に凹陥したものであり、補助係止凸部１３は、嵌合凹条２１の内側面の中央部付近から外側方へ突出したものである。なお、前記主係止凸部１２、補助係止凹部１３、主係止凹部２２、及び補助係止凸部２３は、前記嵌合凸条１１及び嵌合凹条２１の周側面全体に渡って延設しても、該周側面に所定間隔で列設してもよい。
【００２２】
容器本体１０を蓋体２０で封止した状態では、図３に示すように、容器本体１０の嵌合凸条１１と蓋体２０の嵌合凹条２１とが嵌合することにより、容器本体１０と蓋体２０との水平方向の位置が規制され、さらに、嵌合凸条１１の主係止凸部１２及び補助係止凹部１３が、嵌合凹条２１の主係止凹部２２及び補助係止凸部２３と夫々係合することにより、蓋体２０が垂直方向に外れる方向の力Ｆ１や、ねじれ方向の力Ｆ２に抗して、嵌合凸条１１と嵌合凹条２１との嵌合状態が強固に維持される。従って、蓋体２０による容器本体１０の封止力が強固なものとなり、且つ密閉力も高くなる。
【００２３】
なお、前記主係止凸部１２、補助係止凹部１３、主係止凹部２２、及び補助係止凸部２３の膨出又は凹陥は、前述した方向や組合せに限定されるものではなく、適宜、膨出又は凹陥方向やその組合せを変更することが可能である。また、補助係止凹部１３及び補助係止凸部２３は、主係止凸部１２及び主係止凹部２２を補完して係合力を増加させる目的で設けられているが、手提げ容器１００の使用目的等を考慮して、主係止凸部１２と主係止凹部２２との係合力で十分な場合には省くことも可能である。
【００２４】
また、容器本体１０の嵌合凸条１１と蓋体２０の嵌合凹条２１とを嵌合させる際には、図４に示すように、前記主係止凸部１２等が一時的に圧潰されながら、嵌合凸条１１が嵌合凹条２１内に嵌入されるが、当該嵌合途中に嵌合凸条１１と嵌合凹条２１とで囲繞された密閉空間Ｃが形成されることがあり、前述したように、主係止凸部１２及び補助係止凹部１３が、主係止凹部２２又は補助係止凸部２３に夫々係合するまで、嵌合凸条１１と嵌合凹条２１とを完全に嵌合させるには、該密閉空間Ｃに残留した空気を圧縮しながら嵌合凸条１１を嵌合凹条２１内に押し込む必要が生じ、その結果、当該嵌合に要する力が増大する。また、嵌合後も、圧縮された空気が嵌合凹条２１内に残留し、これが反力となって蓋体２０の浮き上がりが生じることもある。これを解消するには、図に示すように、蓋体２０の嵌合凹条２１から外部へ通ずる排気孔２４を貫穿すればよい。該排気孔２４を嵌合凹条２１に所定間隔で複数設けることにより、密閉空間Ｃが生じたり、嵌合部に圧縮空気が残留することがなく、嵌合凸条１１と嵌合凹条２１との嵌合、即ち閉蓋作業が容易となり、蓋体２０の浮き上がりも防止される。
【００２５】
さらに、容器本体１０の側壁には、図１に示すように、容器本体１０の上端面から垂直方向に２つのスリット溝１４が並設されている。該スリット溝１４は、手提げ部材３０を装着するためのものであり、２つのスリット溝１４の間隔は、手提げ部材３０の長手方向の寸法を考慮して設定されている。図５は、スリット溝１４の断面を示す部分断面図であるが、図に示すように、スリット溝１４の断面は、容器本体１０の側壁の外面から厚み方向へ所定深さ凹欠され、さらに、その奥部から側壁の略長さ方向へ左右に所定長さ凹欠された所謂Ｔ字形となっている。これにより、容器本体１０の側壁内に、容器及び収納品の荷重Ｇを支持するための鍔部１５が形成される。
【００２６】
また、前記スリット溝１４は、図６に示すように、容器本体１０の側壁の縁部１４ａから中央部１４ｂへ向かってＴ字形が縮幅されている。スリット溝１４には、図１に示すように、前記縁部１４ａから手提げ部材３０の嵌装部３２が嵌入されるが、該縁部１４ａにおいては手提げ部材３０を嵌入しやすいように、スリット溝１４が手提げ部材３０の嵌装部３２より若干大きく形成されており、前記中央部１４ｂへ向かってスリット溝１４が徐々に縮幅されて、中央部１４ｂにおいては手提げ部材３０の嵌装部３２より若干小さくなるように形成されている。従って、縁部１４ａから中央部１４ｂへ向かっては手提げ部材３０の嵌装部３２を圧入することとなるが、容器本体１０は発泡合成樹脂からなるものであり、適当な弾力性を有するので、発泡合成樹脂を若干圧潰しながら圧入することは容易である。これにより、縁部１４ａでは手提げ部材３０の嵌装部３２をスリット溝１４へ嵌入しやすくなり、一方、中央部１４ｂではスリット溝１４の内面と手提げ部材３０の嵌装部３２の表面とが密接し、その接触面に生じる摩擦力により手提げ部材３０が中央部１４ｂで固定されるようになる。
【００２７】
なお、本実施の形態では、スリット溝１４のＴ字形が均等に縮小されているが、例えばスリット溝１４の形状のうち、側壁の略長さ方向へ凹欠された部分のみを縮小する等、その形状を部分的に縮小することによっても同様の作用を発揮させることが可能である。
【００２８】
また、前記スリット溝１４は、本発明に係るスリット溝の一例であり、前記鍔部１５が容器本体１０の側壁内に形成されるような他の形状、例えば図７（ａ）に示すようなＬ字形や、図７（ｂ）に示すような十字形とすることもできる。また、スリット溝１４の奥部から側壁の略長さ方向へ凹欠される方向は厳密なものではなく、鍔部１５が形成されものであれば、例えば図７（ｃ）に示すように、該方向が側壁の長さ方向から多少ズレていてもよい。
【００２９】
また、前記中央部１４ｂは、手提げ部材３０を装着した場合に、所望の品物が収容され蓋体２０で封止された容器本体１０を手提げ部材３０でバランス良く担持できる位置が好適である。一般的に、容器本体１０の底部の厚みは蓋体２０より厚く設計されていることが多いので、このような容器自体の偏重も考慮に入れて前記中央部１４ｂの位置を設定する。一方、前記縁部１４ａは、容器本体１０の上端面に限られず、例えば容器本体１０の底面を縁部１４ａとして、上方向へスリット溝１４を形成したり、隣接する側壁の外面を縁部１４ａとして、水平方向へスリット溝１４を形成することも可能である。
【００３０】
ここで、容器本体１０の側壁の厚みが薄く、スリット溝１４により形成される鍔部１５が、容器及び収納品の重量を支持するに十分な強度を有しない場合には、図８に示すように、容器本体１０の側壁を厚み方向に膨出させた補強部１６を設け、スリット溝１４により形成される鍔部１５の厚みを増加させることにより、容器及び収納品の重量を支持するに必要な強度を該鍔部１５に付与することができる。なお、図８（ａ）は容器本体１０の側壁を外側ヘ、図８（ｂ）は容器本体１０の側壁を内側へ膨出させて、補強部１６を夫々形成したものであるが、補強部１６を側壁の外側ヘ形成すれば、前述した従来の手提げ容器の突出部よりは突出幅が小さいものの、手提げ容器１００の梱包又は積載時に補強部１６の幅分だけ若干の隙間が生じることとなる。一方、補強部１６を側壁の内側ヘ形成すれば、前記隙間は生じないが容器の収容量が若干減少する。従って、補強部１６をいずれの方向へ膨出させるかは、本手提げ容器１００の用途等を踏まえた上で、当該利点及び不利益を比較考慮して適宜設定する。
【００３１】
前記手提げ部材３０は、図９に示すように、帯状の持ち手部３１の両端に、前記スリット溝１４と略同形、即ち、断面がＴ字形の嵌装部３２が形成されてなるものであり、該嵌装部３２が各スリット溝１４に夫々嵌装されることにより、容器本体１０に着脱可能となっている。また、手提げ部材３０は、ポリエチレン等の合成樹脂が成形されてなるものであり可撓性を有する。
【００３２】
図１０は、前記手提げ部材３０の部分断面図であり、図に示すように、嵌装部３２の断面はスリット溝１４と略同形のＴ字形である。一方、持ち手部３１には、その両端近傍に厚みの薄い易撓部３１ａが形成されている。該易撓部３１ａの厚みは、持ち手部３１の厚みの略１／２程度であり、具体的には１，２ｍｍが好適である。前述したように、持ち手部３１は可撓性を有するものであるが、易撓部３１ａが形成されることにより、持ち手部３１中央より易撓部３１ａが撓み易くなり、手提げ部材３０を容器本体１０に装着する際には、図に示すように、持ち手部３１の中央より易撓部３１ａが大きく撓んで略Ｕ字形となる。これにより、容器本体１０のスリット溝１４の位置や間隔に対して自由度が増して、スリット溝１４への装着作業が容易になる。また、持ち手部３１の中央は大きく撓むことがないので、握り易い形状となる。
【００３３】
なお、前記手提げ部材３０の長さや幅は特に限定されるものではなく、容器本体１０の大きさや持ち易さ等を考慮して適宜設定する。また、前記手提げ部材３０の嵌装部３２は、前述したようにスリット溝１４と略同形であり、図７に示したようなスリット溝１４の各形状に合せて、図１１（ａ）に示すＬ字形、図１１（ｂ）に示す十字形、図７（ｃ）に示す形状とすることができる。
【００３４】
図１２は、容器本体１０に手提げ部材３０を装着して、手提げで持ち運ぶ状態の手提げ容器１００を示したものである。容器本体１０には所望の品物が収容されており、予め或いは品物を収容する際等に、図１に示すように、手提げ部材３０は、Ｕ字形に変形されてスリット溝１４に嵌装される。所望の品物を収容した後、容器本体１０は蓋体２０により閉蓋されて強固に封止される。その後、前記手提げ部材３０が上側となるように容器本体１０を横転させる。これにより、図１２に示すように、手提げ部材３０を握持して持ち運ぶことが可能となる。容器本体１０を横転させても、前述したように、容器本体１０と蓋体２０とは強固に嵌合されているので、持ち運び中に蓋体２０が外れることはない。
【００３５】
図１３は、手提げ部材３０が装着された容器本体１０の側壁の断面を示すものであるが、手提げ部材３０の持ち手部３１を握持して運ぶ際には、スリット溝１４により形成された鍔部１５を手提げ部材３０の嵌装部３２が担持することにより、容器及び収納品の荷重Ｇが支持される。また、手提げ状態では、前記手提げ部材３０が荷重Ｇを受けて、持ち手部３１を握持する手に沿って適度に撓むので、持ち易いという利点がある。
【００３６】
なお、容器本体１０と蓋体２０とは強固に嵌合されており密閉性も高いが、本手提げ容器１００に冷蔵品や冷凍品等を収容し、容器本体１０を横転させた状態で長時間持ち運んだ場合に、冷蔵品等に結露した水滴や霜等が容器本体１０と蓋体２０との嵌合部から滲出する可能性もある。これを解消するためには、図１４に示すように、手提げ部材３０が装着される容器本体１０の側壁と対向する側壁の内面に、複数の凹陥部１７を形成すればよい。これにより、手提げ容器１００を持ち運んでいる状態では、凹陥部１７に前記水滴等が貯留されるので、容器本体１０と蓋体２０との嵌合部に水滴等が溜まることがなく、水滴等の滲出を抑制することができる。
【００３７】
【発明の効果】
以上説明したように、本発明によれば、発泡合成樹脂製の容器に手提げ部材が着脱可能に設けられてなる手提げ容器であって、前記容器の側壁の外面から略厚み方向へ凹欠され、且つ、その所定深さから側壁の略長さ方向へ凹欠されたスリット溝が、該側壁の縁部から中央近傍に延設され、前記手提げ部材の端部に、前記スリット溝と略同形状の嵌装部が形成されたものとしたので、前記手提げ部材の嵌装部をスリット溝に嵌めることにより、容器の側壁に手提げ部材が装着され、該容器を横転させた状態で手提げ部材を握って容器を持ち運ぶことができ、梱包等の際には手提げ部材を取り外して容器内等に収容しておくことができる。
よって、従来の手提げ容器のように側壁から突出する部材がなく、梱包効率や積載効率を低下させることがない。また、前記スリット溝は、容器の発泡成形の際に形成することが可能なので、部品点数の増加や作業数の増加を伴わず、コストアップもない。さらに、手提げ部材は使用者が必要に応じて容易に着脱できるものなので、従来のような手提げ紐の取付け作業も不要である。また、手提げ部材は適宜市販のものを採用し、スリット溝の断面形状を該手提げ部材の嵌装部に合致させることにより、本発明を容易且つ安価に実施できるという利点もある。

[Prior art]
Foamed synthetic resin containers have high heat insulation properties and can be kept cold for a long time by adding ice, cooling agent, dry ice, etc., so that fresh food such as marine products that need to be refrigerated It is used as a container for transporting foods and cold-preserved foods such as ice cream. Furthermore, since it is excellent in water resistance and shock absorption and is lightweight, it is also used for transporting pharmaceuticals, precision equipment, and the like.
[0003]
Such foamed synthetic resin containers include, in addition to large-sized containers for business use, small containers having relatively small capacities as insulated containers until souvenirs sold over the counter can be taken home by the purchaser. However, some containers that store goods that can be carried and carried by a purchaser or the like are provided with a carrying string for convenience of carrying.
[0004]
FIG. 15 shows an example of a conventional foamed synthetic resin container provided with a hand strap. A conventional hand held container 80 includes a main body 81 and a lid 82 made of a foamed synthetic resin. Then, projecting portions 83 are formed outwardly from two side walls at positions opposing the main body 81, and two through holes 84 penetrating the projecting portion 83 in the vertical direction are formed in each projecting portion 83 at predetermined intervals. It is pierced, and one hand strap 85 is inserted into the two through holes 84 and tied in a ring. Thereby, the user can carry the hand-carried container 80 containing desired articles by holding the two hand-carried cords 85 together with one hand or by passing the arm through the hand-carried cord 85 and hanging from the shoulder.
[0005]
[Problems to be solved by the invention]
The protrusion 83 has a shape and a size in consideration of a width sufficient to form the through-hole 84 and a strength sufficient to support the load of the carrying container 80 accommodating a desired item. When a large number of handbags 80 are divided into several rows and stacked and packed in order to mass-produce, store, and transport the containers 80, a space is created between the stacked handbags 80 by the amount of the protruding portion 83. Becomes inefficient. Similarly, there is a problem in that the loading efficiency is deteriorated even when loading on a carrier bed of a transport vehicle, and as a result, warehouse costs and transport costs increase. Furthermore, in the state of storage, transportation, etc., there is also a problem that the carrying string 85 is loosened and hangs down from the side wall of the carrying container 80, which hinders the packing work and the carrying work, and has a problem that the appearance is poor.
[0006]
On the other hand, FIG. 16 shows another conventional container made of a foamed synthetic resin, and the hand-held container 90 has a main body 91 and a lid 92 made of a foamed synthetic resin. A concave groove 93 is provided in parallel from the side wall of the main body 91 to the bottom surface and further to the opposing side wall. After an annular hand strap 94 is inserted into the concave groove 93, a string is formed on the side wall portion of the concave groove 93. The carrying string 94 is fixed to the main body 91 by fitting the fixing member 95. Since the present carrying container 90 does not have a protruding portion on the side wall unlike the carrying container 80, there is an advantage that the packing efficiency and the loading efficiency do not decrease as described above, but the problem that the carrying string 94 hangs down. Remains. Further, in addition to the main body 91 and the lid 92, it is necessary to separately form the fixing member 95, which causes a problem that the cost is increased.
[0007]
Further, as proposed in Japanese Patent Application Laid-Open No. 2002-104426, a string storage groove for accommodating the slack carrying string 95 is provided on the bottom surface of the main body 91, and the strap is provided from the string storage groove as necessary. A carrying container that pulls out the cord 95 and uses it has been proposed, but the carrying container also requires a fixing member as in the case of the carrying container 90. Also, since it is difficult to mechanically perform the work of attaching a member that cannot maintain a constant shape, such as a hand strap, it is attached manually, but the strap is tied or stored in the string storage groove. The work is laborious and increases the production costs.
[0008]
The present invention has been made in view of these problems, and like a conventional hand-held container, is a lightweight container having excellent heat insulation, water resistance, and shock absorption, and has a reduced packing efficiency and a reduced loading efficiency. It is an object of the present invention to provide a carrying container which does not increase the number of parts and does not increase the number of parts and does not complicate the operation of attaching the carrying string.
[0009]
[Means for Solving the Problems]
The carrying container according to the present invention is a carrying container in which a carrying member is detachably provided on a container made of a foamed synthetic resin, and is concavely notched in an approximately thickness direction from an outer surface of a side wall of the container, and has a predetermined shape. A slit groove recessed in the length direction of the side wall from the depth is extended from the edge of the side wall to the vicinity of the central portion, and fitted into an end of the hand-carrying member in the same shape as the slit groove. The part is formed. By fitting the fitting portion of the hand-carrying member into the slit groove, the hand-carrying member is mounted on the side wall of the container, and the container can be carried by holding the hand-carrying member in a state where the container is turned over, such as when packing. By storing in a container or the like with the carrying member removed, there is no member protruding from the side wall of the container, and the packing efficiency and the loading efficiency are not reduced.
[0010]
Examples of the foamed synthetic resin used for the container include a styrene-based resin such as polystyrene and an olefin-based resin such as polyethylene and polypropylene. It is preferable to use foamed polystyrene from the viewpoint of moldability and cost. Also, as a method for molding the foamed synthetic resin, for example, when foamed polystyrene is used, in-mold foam molding using a mold or the like can be employed.
[0011]
The container has a main body and a lid, and a fitting ridge or a fitting ridge is formed on an upper end surface of the main body and a lower end surface of the lid, respectively. A locking projection or a locking recess is formed on each side surface of the mating ridge and the fitting ridge, respectively, and the fitting ridge and the fitting dent are fitted and engaged with the locking ridge. The main body is sealed with the lid by the engagement of the stop recesses. Thereby, the fitting between the main body and the lid becomes strong, and the lid does not come off from the main body even when the container is turned over when a desired item is stored in the container and carried.
[0012]
The side wall on which the slit groove is to be provided is arbitrary. For example, a long side wall or a short side wall may be used in a cubic container. Further, slit grooves may be respectively provided on the long side wall and the short side wall, and it may be possible to appropriately select which slit groove the hand-held member is fitted in according to the convenience of the user.
[0013]
In addition, the slit groove which is recessed in the thickness direction from the outer surface of the side wall of the container and is recessed in the length direction of the side wall from a predetermined depth is, for example, an L-shaped cross section, a hook shape, Although it includes a T-shaped member, it is preferable that the slit groove and the end portion of the hand-held member be substantially T-shaped in consideration of the convenience of attaching and detaching the hand-held member and the efficiency of supporting the load of the container. is there. Further, the slit groove extends from the edge of the side wall of the container to the vicinity of the center, and the edge may be formed on any one of the upper surface, the bottom surface, and the outer surface of another side wall adjacent to the side wall. It may be. On the other hand, the vicinity of the central portion refers to a united periphery including the central portion of the side wall (hereinafter, sometimes simply referred to as the central portion).
[0014]
Further, it is preferable that the width of the slit groove is reduced from the edge of the side wall toward the vicinity of the center. As a result, when the carrying member is fitted into the slit groove, it is press-fitted into the central portion, so that the inner surface of the slit groove and the surface of the fitting portion of the carrying member come into close contact with each other, and the carrying member is formed by frictional force generated on the contact surface. Is fixed at the fitting position near the center of the side wall, and does not slide in the edge direction during carrying. Here, the reduced width of the slit groove means that the width of the concave portion is reduced. For example, in the case of a T-shaped portion, the T-shaped portion is reduced uniformly, or the concave portion of an arbitrary portion of the T-shaped portion is formed. It means that the width is reduced.
[0015]
Further, when the thickness of the side wall of the container is small and does not have sufficient strength to support the weight of the container, the side wall of the container is bulged in the thickness direction around the position where the slit groove is to be formed. By providing such a reinforcing portion, the strength required for carrying can be imparted to the side wall of the container.
[0016]
Further, it is preferable that the hand-carrying member has flexibility. Thereby, for example, the degree of freedom is increased with respect to the position and the interval of the slit groove, and the fitting of the hand-carrying member is facilitated, and further, when carrying in the hand-carrying state, the hand-carrying member is appropriately bent by the load of the container or the like and held. The ease is also improved. Examples of such a flexible material include synthetic resins such as polypropylene, polyethylene, polystyrene, polyester, and vinyl chloride, and those obtained by pressing pulp. Synthetic resins are preferred from the viewpoint of performance.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the carrying container according to the embodiment of the present invention will be specifically described with reference to the drawings. Note that this embodiment is an example, and the present invention is not limited to the embodiment.
[0018]
FIG. 1 is an exploded perspective view of a carrying container according to an embodiment of the present invention. As shown in the figure, the present carrying container 100 includes a hollow rectangular parallelepiped container main body 10 having an open top, a lid 20 for sealing the opening of the container main body 10, and a hand carrying member 30 detachable from the container main body 10. It is provided with.
[0019]
The container body 10 and the lid 20 are made of a foamed synthetic resin obtained by foaming prefoamed beads of expanded polystyrene in a predetermined mold, respectively. Is formed in an annular shape, while a fitting concave ridge 21 is formed in a lower end surface of the lid 20 in an annular shape. Are sealed by the lid 20.
[0020]
FIG. 2 is a partial cross-sectional view showing an example of the fitting structure. The fitting ridge 11 formed on the upper end surface of the container main body 10 extends vertically from the upper end surface along the inner wall surface of the container main body 10. The width W1 is about half the thickness W0 of the side wall of the container body 10. Further, the height H1 of the fitting ridge 11 is a height sufficient to restrict the displacement of the lid 20 in the horizontal direction, and is appropriately set in consideration of the thickness of the lid 20. Further, a main locking projection 12 is formed on the outer surface of the fitting projection 11, and an auxiliary locking recess 13 is formed on the inner surface. The main locking projection 12 is a dome-shaped bulge outward from the upper side of the outer surface of the fitting ridge 11, and the auxiliary locking recess 13 is a central portion of the inner surface of the fitting ridge 11. It is recessed outward from the vicinity, that is, in the same direction as the bulging direction of the main locking projection 12. The auxiliary locking concave portion 13 is smaller than the main locking convex portion 12. Specifically, the auxiliary locking concave portion 13 has a height H2 in the bulging direction of the main locking convex portion 12 and a height H2 in the concave direction of the auxiliary locking concave portion 13. When the height H3 is approximately 1/3, a sufficient locking force can be exerted, and the height H3 can be easily removed from the molding die.
[0021]
On the other hand, the fitting concave ridge 21 formed on the lower end surface of the lid 20 is recessed at a position corresponding to the fitting convex ridge 11 so that its width and height also match the fitting convex ridge 11. Is set to A main locking concave portion 22 and an auxiliary locking convex portion 23 corresponding to the main locking convex portion 12 and the auxiliary locking concave portion 13 are formed on the outer side surface and the inner side surface of the fitting concave strip 21, respectively. The shapes of the main locking concave portion 22 and the auxiliary locking convex portion 23 match the main locking convex portion 12 and the auxiliary locking concave portion 13, respectively. The auxiliary locking projection 13 protrudes outward from the vicinity of the center of the inner surface of the fitting groove 21 outwardly from the upper part of the side surface in a dome shape. The main locking projection 12, the auxiliary locking recess 13, the main locking recess 22, and the auxiliary locking projection 23 extend over the entire peripheral side surface of the fitting ridge 11 and the fitting ridge 21. They may be extended or may be arranged at predetermined intervals on the peripheral side surface.
[0022]
In a state where the container main body 10 is sealed with the lid 20, as shown in FIG. 3, the fitting ridge 11 of the container main body 10 and the fitting concave ridge 21 of the lid 20 fit together to form the container main body 10. The horizontal position between the cover 10 and the lid 20 is regulated, and the main locking protrusions 12 and the auxiliary locking recesses 13 of the fitting ridges 11 are connected to the main locking recesses 22 and the auxiliary locking recesses 22 of the fitting ridges 21. By engaging with the locking projections 23, respectively, the fitting protrusion 11 and the fitting recess 21 are opposed to each other by the force F1 in the direction in which the lid 20 is disengaged in the vertical direction and the force F2 in the torsion direction. The fitted state is firmly maintained. Accordingly, the sealing force of the container body 10 by the lid 20 becomes strong and the sealing force becomes high.
[0023]
In addition, the bulges or depressions of the main locking convex portion 12, the auxiliary locking concave portion 13, the main locking concave portion 22, and the auxiliary locking convex portion 23 are not limited to the above-described directions and combinations, and may be appropriately determined. It is possible to change the direction of the bulge or depression or a combination thereof. The auxiliary locking concave portion 13 and the auxiliary locking convex portion 23 are provided for the purpose of increasing the engaging force by complementing the main locking convex portion 12 and the main locking concave portion 22. In consideration of the purpose and the like, if the engagement force between the main locking projection 12 and the main locking recess 22 is sufficient, it can be omitted.
[0024]
When the fitting ridges 11 of the container body 10 and the fitting ridges 21 of the lid 20 are fitted together, as shown in FIG. While the fitting ridge 11 is fitted into the fitting dent 21, a closed space C surrounded by the fitting ridge 11 and the fitting ridge 21 is formed during the fitting. As described above, until the main locking convex portion 12 and the auxiliary locking concave portion 13 engage with the main locking concave portion 22 or the auxiliary locking convex portion 23, respectively, In order to completely fit the ridge 21, it is necessary to push the fitting ridge 11 into the fitting concave ridge 21 while compressing the air remaining in the closed space C, and as a result, the fitting is required. Power increases. Further, even after the fitting, the compressed air remains in the fitting recess 21, and this acts as a reaction force to cause the lid 20 to float. In order to solve this, as shown in the figure, it is only necessary to penetrate the exhaust hole 24 communicating from the fitting recess 21 of the lid 20 to the outside. By providing a plurality of the exhaust holes 24 in the fitting recesses 21 at predetermined intervals, a closed space C does not occur, and compressed air does not remain in the fitting portion. , I.e., the operation of closing the cover, becomes easy, and the lifting of the cover 20 is also prevented.
[0025]
Further, as shown in FIG. 1, two slit grooves 14 are provided in a side wall of the container body 10 in a vertical direction from an upper end surface of the container body 10. The slit groove 14 is for mounting the hand-held member 30, and the interval between the two slit grooves 14 is set in consideration of the longitudinal dimension of the hand-held member 30. FIG. 5 is a partial cross-sectional view showing a cross section of the slit groove 14. As shown in the drawing, the cross section of the slit groove 14 is notched by a predetermined depth in the thickness direction from the outer surface of the side wall of the container body 10. It has a so-called T-shape that is recessed by a predetermined length from left to right in the direction of the length of the side wall. As a result, a flange 15 for supporting the load G of the container and the stored articles is formed in the side wall of the container body 10.
[0026]
As shown in FIG. 6, the slit groove 14 has a T-shape narrowing from the edge 14a of the side wall of the container body 10 toward the center 14b. As shown in FIG. 1, the fitting portion 32 of the hand-held member 30 is fitted into the slit groove 14 from the edge portion 14a. The slit groove 14 is formed at the edge portion 14a so that the hand-held member 30 can be easily fitted. 14 is formed slightly larger than the fitting portion 32 of the hand-carrying member 30, and the slit groove 14 is gradually narrowed toward the central portion 14b. It is formed to be slightly smaller. Therefore, the fitting portion 32 of the hand-held member 30 is press-fitted from the edge portion 14a toward the center portion 14b. However, since the container body 10 is made of a foamed synthetic resin and has appropriate elasticity, It is easy to press-fit the foamed synthetic resin while slightly crushing it. Thereby, the fitting portion 32 of the hand-held member 30 is easily fitted into the slit groove 14 at the edge portion 14a, while the inner surface of the slit groove 14 and the surface of the fitted portion 32 of the hand-held member 30 are in close contact with each other at the central portion 14b. Then, the hand-held member 30 is fixed at the central portion 14b by the frictional force generated on the contact surface.
[0027]
In the present embodiment, the T-shape of the slit groove 14 is uniformly reduced. For example, in the shape of the slit groove 14, only a portion of the shape of the side wall which is notched in the substantially length direction is reduced. A similar effect can be exerted by partially reducing the shape.
[0028]
Further, the slit groove 14 is an example of the slit groove according to the present invention, and has another shape such that the flange portion 15 is formed in the side wall of the container body 10, for example, as shown in FIG. An L-shape or a cross as shown in FIG. Further, the direction in which the side wall of the slit groove 14 is recessed in the substantially length direction of the side wall is not strict, and if the flange portion 15 is formed, for example, as shown in FIG. The direction may be slightly shifted from the length direction of the side wall.
[0029]
In addition, it is preferable that the central portion 14b is a position where the container main body 10 in which a desired article is accommodated and which is sealed with the lid 20 can be supported by the hand-held member 30 with good balance when the hand-held member 30 is mounted. In general, the bottom of the container body 10 is often designed to be thicker than the lid 20, so the position of the central portion 14b is set in consideration of such uneven weight of the container itself. On the other hand, the edge 14a is not limited to the upper end surface of the container main body 10. For example, the bottom surface of the container main body 10 is used as the edge 14a, and the slit 14 is formed in the upward direction. It is also possible to form the slit groove 14 in the horizontal direction.
[0030]
Here, when the thickness of the side wall of the container main body 10 is small and the flange portion 15 formed by the slit groove 14 does not have sufficient strength to support the weight of the container and the stored articles, as shown in FIG. In order to support the weight of the container and the stored articles, a reinforcing portion 16 is formed by bulging the side wall of the container body 10 in the thickness direction and the thickness of the flange portion 15 formed by the slit groove 14 is increased. Strong strength can be imparted to the flange portion 15. 8A shows the case where the side wall of the container body 10 is extended outward, and FIG. 8B shows the case where the side wall of the container body 10 is expanded inward to form the reinforcing portions 16. If the outer wall 16 is formed on the outer side of the side wall, although the protrusion width is smaller than that of the above-described conventional hand-held container, a slight gap is generated by the width of the reinforcing portion 16 when the hand-held container 100 is packed or loaded. . On the other hand, if the reinforcing portion 16 is formed inside the side wall, the clearance does not occur, but the capacity of the container is slightly reduced. Therefore, in which direction the reinforcing portion 16 is expanded is appropriately set in consideration of the advantages and disadvantages in consideration of the use of the present carrying container 100 and the like.
[0031]
As shown in FIG. 9, the hand-carrying member 30 has a fitting portion 32 having substantially the same shape as the slit groove 14, that is, a T-shaped cross section, formed at both ends of a band-shaped handle portion 31. The fitting portion 32 is fitted into each of the slit grooves 14 so that the fitting portion 32 can be attached to and detached from the container body 10. The hand-held member 30 is formed by molding a synthetic resin such as polyethylene and has flexibility.
[0032]
FIG. 10 is a partial cross-sectional view of the hand-carrying member 30. As shown in the drawing, the cross section of the fitting portion 32 is a T-shape substantially the same as the slit groove 14. On the other hand, the handle portion 31 has thin flexible portions 31a formed near both ends thereof. The thickness of the flexible portion 31a is about 1/2 of the thickness of the handle portion 31, and specifically, it is preferably 1,2 mm. As described above, the handle portion 31 has flexibility. However, by forming the easy-flexible portion 31a, the easy-flexible portion 31a is easily bent from the center of the handle portion 31, and When attached to the container body 10, as shown in the figure, the easily flexible portion 31a is largely bent from the center of the handle portion 31 to have a substantially U-shape. Thereby, the degree of freedom with respect to the position and interval of the slit groove 14 of the container body 10 is increased, and the work of mounting the slit groove 14 is facilitated. Further, since the center of the handle portion 31 does not bend significantly, the shape becomes easy to grasp.
[0033]
Note that the length and width of the hand-held member 30 are not particularly limited, and are appropriately set in consideration of the size and the ease of holding the container body 10. The fitting portion 32 of the hand-held member 30 has substantially the same shape as the slit groove 14 as described above, and is shown in FIG. 11A according to each shape of the slit groove 14 as shown in FIG. An L shape, a cross shape shown in FIG. 11B, and a shape shown in FIG.
[0034]
FIG. 12 shows the hand-held container 100 in a state where the hand-held member 30 is attached to the container main body 10 and carried by hand. A desired article is accommodated in the container body 10, and the hand-held member 30 is deformed into a U-shape and fitted in the slit groove 14 as shown in FIG. . After accommodating a desired item, the container body 10 is closed by the lid 20 and tightly sealed. Thereafter, the container main body 10 is turned over so that the hand-held member 30 faces upward. Thereby, as shown in FIG. 12, it is possible to grip and carry the hand-carrying member 30. Even if the container main body 10 is turned over, as described above, the container main body 10 and the lid 20 are firmly fitted, so that the lid 20 does not come off during transportation.
[0035]
FIG. 13 shows a cross section of the side wall of the container main body 10 on which the hand-held member 30 is mounted. When the handle portion 31 of the hand-held member 30 is gripped and carried, the slit is formed by the slit groove 14. By supporting the flange portion 15 with the fitting portion 32 of the hand-held member 30, the load G of the container and the stored article is supported. In the hand-held state, the hand-held member 30 receives the load G and bends appropriately along the hand holding the handle portion 31, so that there is an advantage that the hand-held member 30 is easy to hold.
[0036]
The container main body 10 and the lid 20 are firmly fitted to each other and have high airtightness. However, when the refrigerator 100 or the frozen product is stored in the present carrying container 100 and the container main body 10 is turned over for a long time, When carried, there is a possibility that water droplets, frost, and the like condensed on the refrigerated product or the like may seep out from the fitting portion between the container main body 10 and the lid 20. In order to solve this, as shown in FIG. 14, a plurality of recesses 17 may be formed on the inner surface of the side wall facing the side wall of the container body 10 to which the hand-held member 30 is mounted. Accordingly, in a state where the carrying container 100 is being carried, the water droplets and the like are stored in the concave portion 17, so that the water droplets and the like do not accumulate in the fitting portion between the container main body 10 and the lid 20, and the water droplets and the like do not accumulate. Exudation can be suppressed.
[0037]
【The invention's effect】
As described above, according to the present invention, a hand-held container in which a hand-held member is detachably provided on a container made of a foamed synthetic resin, is concavely notched in an approximately thickness direction from an outer surface of a side wall of the container, A slit groove recessed from the predetermined depth in a substantially longitudinal direction of the side wall is extended from the edge of the side wall to near the center, and an end of the hand-carrying member has substantially the same shape as the slit groove. Since the fitting portion of the hand-held member is formed in the slit groove, the hand-held member is mounted on the side wall of the container, and the hand-held member is gripped in a state where the container is turned over. The container can be carried around, and the carrying member can be removed and stored in the container or the like at the time of packing or the like.
Therefore, there is no member protruding from the side wall unlike the conventional hand-held container, and the packing efficiency and the loading efficiency are not reduced. Further, since the slit groove can be formed at the time of foam molding of the container, the number of parts and the number of operations are not increased, and the cost is not increased. Further, since the user can easily attach and detach the hand-carrying member as needed, it is not necessary to attach a hand-carrying string as in the related art. In addition, there is an advantage that the present invention can be easily and inexpensively implemented by appropriately adopting a commercially available hand-held member and matching the cross-sectional shape of the slit groove with the fitting portion of the hand-held member.
