Description

【０００１】
【発明の属する技術分野】
本発明は、主に野菜等の運搬等に使用される組立式箱に関する。
【０００２】
【従来の技術】
従来、野菜等の運搬や保管には、段ボール紙製の箱が用いられており、このような段ボール箱の一例として図１１に示す如きものが知られている（例えば、特許文献１を参照）。
【０００３】
この箱１は、図１２の如く形成された板状材を組立てることにより形成され、折り目を介して一体に連接された左側板２、前側板３、右側板４及び背側板５が、左側板２の前側板３とは反対側の縁部を糊代６を介して背側板５の縁部にホッチキス形の止め金具や接着等により固定することによって箱の側壁部を形成し、左側板２及び右側板４の上下縁部にそれぞれ折り目を介して一体化された一対の内フラップ板７，７と、前側板３及び背側板５の上下縁部にそれぞれ折り目を介して一体化された一対の外フラップ板８，８とにより底部及び蓋部を形成するようになっている。
【０００４】
この底部又は蓋部は、両外フラップ８，８を突き合わせ、その突き合わせ箇所に沿って粘着テープ９を貼り付けたり、外フラップ８，８を表面側からホッチキス形の止め金具で内フラップ７，７に止着したりして形成される。
【０００５】
【特許文献１】
特開平９−３０１３４１号公報（００１４段落、図１，図２）
【０００６】
【発明が解決しようとする課題】
しかし、上述のような従来の技術では、箱を組み立てる際に止め金具や粘着テープ等を用いる為に組み立てることが煩雑になり、一方、箱を解体する際にも止め金具を外したり接着テープを剥がしたりしなければならないので、作業が煩雑になり、また、止め金具を外したり接着テープを剥がしたりする際に、段ボール箱が破損して綺麗な状態で再度利用ができないという問題がある。
【０００７】
また、ホッチキス形の止め金具を使用する場合、止め金具が誤って野菜などの収容物に混入してしまうおそれがあり、更には、底部を粘着テープを用いて形成した場合、強度的に不安があり、収容物が重量の嵩むものであれば、底が抜けしてしまうおそれがあった。
【０００８】
本発明は、このような従来の技術の状況を鑑み、止め金具や粘着テープ等を用いることなく、容易に組立て及び分解ができる上面に開閉可能な蓋部を備えた組立式箱の提供を目的とする。
【０００９】
【課題を解決するための手段】
上述の如き従来の問題を解決し、所期の目的を達成するための請求項１の組立式箱は、四角形の底板と、該底板の前背左右の各縁部にそれぞれ折り目を介して一体に形成された前側板、背側板、左側板及び右側板と、前記前側板と前記左側板の各側辺間を連結し、前記底板の隅を始点とした折り目が形成された前左側板間連結板と、前記前側板と前記右側板の各側辺間を連結し、前記底板の隅を始点とした折り目が形成された前右側板間連結板と、前記背側板と前記左側板の各側辺間を連結し、前記底板の隅を始点とした折り目が形成された背左側板間連結板と、前記背側板と前記右側板の各側辺間を連結し、前記底板の隅を始点とした折り目が形成された背右側板間連結板と、前記左側板及び／又は右側板の前記底板とは反対側の縁部に折り目を介して一体に形成された蓋用フラップ板とを備え、前記前側板及び背側板は、前記底板とは反対側の縁部に一定幅を有する上縁板を介して一体に形成された押さえ板をそれぞれ備え、前記押さえ板を前記上縁板の縁部を折り目として折り曲げて前側板及び背側板の内側面に重ね合わせ、前記左側板、右側板及び前記蓋用フラップ板をそれぞれ前記底板側に折り畳んだ状態で全体形状を平板状となし、各側板を前記底板に対して直角に立ち上げ、前記押さえ板の縁部をそれぞれ各連結板及び／又は左右側板に係合させることにより、上面に開閉可能な蓋部を備えた箱状に組み立てられるようにしたことを特徴とする。
【００１０】
このように構成することによって、ホッチキス形の止め金具や粘着テープ等を用いずに、上面に開閉可能な蓋部を備えた箱の組立て及び分解を容易に行うことができる。また、底部が周壁と一体化した一枚の底板からなっているので十分な強度を確保することができ、底抜けに対する十分な耐力を備える。
【００１１】
請求項２の発明は、請求項１の構成に加え、蓋用フラップ板が、両側縁に折り目を介して一体に形成された係止片を備え、前側板及び背側板は、上縁部に前記係止片が係合される係止孔を備えたことを特徴とする。
【００１２】
このように構成することによって、粘着テープやホッチキス形の止め金具等を用いずに、好適に蓋部を閉じた状態にすることができる。
【００１３】
請求項３の発明は、請求項１又は２の構成に加え、左右両蓋用フラップ板を跨いで被せ、前記両蓋用フラップ板間の間隙を閉鎖する蓋用補助板を備えたことを特徴とする。
【００１４】
このように構成することにより、野菜等の収容物が箱内に収まりきらず、蓋用フラップ板が浮き上がって、蓋が閉じられないような場合でも、好適に箱の上面を閉じることができる。
【００１５】
請求項４の発明は、請求項３の構成に加え、蓋用補助板が、縁部に取付用係止片を備え、前記蓋用補助板を蓋用フラップ板に被せた状態で前記取付用係止片を前側板及び背側板の上縁部に形成された係止孔に係止させるようにしたことを特徴とする。
【００１６】
このように構成することによって、野菜等の収容物が箱内に収まりきらず、蓋用フラップ板が浮き上がって、蓋が閉じられないような場合でも、蓋用補助板で蓋用フラップ板を押さえ、箱をそれ以上開かない状態にすることができる。
【００１７】
請求項５の発明は、請求項１〜３又は４の構成に加え、押さえ板が、前側板及び背側板の内側面上端部のみに重なることを特徴とする。
【００１８】
このように構成することによって、箱高さが高いものであっても、材料、即ち展開された板状材の面積が少なく済み経済的である。
【００１９】
請求項６の発明は、請求項１〜４又は５の構成に加え、押さえ板が、その側縁基端側より先端縁側に斜めに向けた折り目を形成して該折り目より折り畳まれる逃がし片部を備えたことを特徴とする。

【００２３】
【発明の実施の形態】
次に、本発明に係る組立式箱の実施の形態を図について説明する。
【００２４】
図１は本発明に係る上面に開閉可能な蓋部を備えた組立式箱の一例を示し、符号２０は組立式箱である。
【００２５】
組立式箱２０は、段ボール紙等の紙製の板状材を図２に示すように組立式箱を展開した状態に打抜き、これを折曲加工することにより形成されている。
【００２６】
この組立式箱２０は、四角形の底板２１と、底板２１の前背左右の縁部にそれぞれ折り目２２〜２５を介して一体に形成された前側板２６、背側板２７、左側板２８及び右側板２９と、前側板２６と左側板２８の各側辺部を連結する前左側板間連結板３０と、前側板２６と右側板２９の各側辺部を連結する前右側板間連結板３１と、背側板２７と左側板２８の各側辺部を連結する背左側板間連結板３２と、背側板２７と右側板２９の各側辺部を連結する背右側板間連結板３３と、左側板２８及び右側板２９に折り目３４，３５を介して一体に形成された一対の蓋用フラップ板３６，３７とを備えている。
【００２７】
前側板２６は、底板２１に折り目２２を介して連続して形成され、その底板２１とは反対側の縁部に前上縁板３８を介して押さえ板３９が一体に形成され、押さえ板３９を前上縁板３８の両縁部を折り目として折り曲げて前側板２６の内側面に重ね合わせ、前押さえ板３９の上縁板３８とは反対側の縁部に形成された接着片３９ａを前側板２６の内側面に接着剤により固着させている。
【００２８】
背側板２７は、底板２１と折り目２３を介して連続して形成され、その折り目２３とは反対側の縁部には、背上縁板４０を介して押さえ板４１が一体に形成され、押さえ板４１を背上縁板４０の両縁を折り目として曲げて背側板２７の内側面に重ね合わせ、押さえ板４１の上縁板４０とは反対側の縁部に形成された接着片４１ａを背側板２７の内側面に接着剤により固着させている。
【００２９】
接着片３９ａ，４１ａは、押さえ板３９，４１の上縁板３８，４０と反対側の縁に切れ目３９ｄ，４１ｄを入れるとともに、縁部と平行に折り目３９ｂ，３９ｃ、４１ｂ，４１ｃを設けることにより形成され、図３に示すように、折り目３９ｂ，３９ｃ、４１ｂ，４１ｃで折り曲げ、折り目３９ｂ、４１ｂを境に縁側のみを接着剤により側板の内側面に固着させる。このようにすることによって上縁板３８，４０の幅が広くとも、無理なく押さえ板３９，４１を前側板２６及び背側板２７に接合することができる。
【００３０】
前上縁板３８及び背上縁板４０は、一定幅を有する細長板状に形成され、前側板２６又は背側板２７の上縁部を構成している。
【００３１】
押さえ板３９，４１は、上縁板３８，４０とその反対側縁部との間の幅が前側板２６又は背側板２７に対して短く形成され、前側板２６及び背側板２７の内側面上端部のみに重なるようになっている。
【００３２】
押さえ板３９，４１には、その側縁基端側より先端縁側に斜めに向けた折り目４２，４２を形成して該折り目４２より折り畳まれる逃がし片部４３，４３を備えている。
【００３３】
押さえ板３９，４１の側縁、即ち逃がし片部４３の側縁には、左側板２８及び右側板２９に対して係止される係合突起４４，４４が形成されている。
【００３４】
左側板２８は、底板２１と折り目２４を介して連続して形成され、その底板２１と反対側の縁部には折り目３４を介して蓋用フラップ板３６が一体に形成されている。
【００３５】
右側板２９は、底板２１と折り目２５を介して連続して形成され、その底板２１と反対側の縁部には折り目３５を介して蓋用フラップ板３７が一体に形成されている。
【００３６】
また、左側板２８及び右側板２９の両側縁には、押さえ板３９，４１の側縁に設けられた係合突起４４が挿入されて係合される係止孔４５，４５が貫通して形成されている。
【００３７】
蓋用フラップ板３６，３７は、折り目３４，３５を回動中心として回動し、箱の上面中央部分で縁部が突き合わされ、箱の上面を覆うようになっている。
【００３８】
この蓋用フラップ板３６，３７には、その両側縁部に折り目を介して係止片４６，４６が一体に形成されており、この係止片４６が前側板２６及び背側板２７の上縁、即ち上縁板３８，４０上に形成された係止孔４７，４７に挿入されて着脱可能に係止されることによって、蓋用フラップ板３６，３７で箱上面を覆い、粘着テープ等を使用しないで蓋部を閉じることができる。
【００３９】
前左側板間連結板３０、前右側板間連結板３１、背左側板間連結板３２及び背右側板間連結板３３は、それぞれ折り目４８を介して固定部４９と可動部５０とから構成され、固定部４９は、接着剤をもって前側板２６及び背側板２７の内面に接着されるようになっている。
【００４０】
尚、組み立てられた際に、各連結板３０，３１，３２，３３の固定部４９と可動部５０とが重なり合った部分の一部が押さえ板３９，４１により押さえられるようになっている。
【００４１】
次に、上記の組立式箱の組立方法について図４、図５を参照して説明する。
【００４２】
まず、図４（ａ）〜（ｂ）に示すように、折り目２４に沿って左側板２８及び蓋用フラップ板３６を内側、即ち底板側に折り曲げ、底板２１に重ねて折り畳む。そして、そのとき一緒に折られる各連結板３０，３２の固定部４９を前側板２６及び背側板２７の重なり合った部分に接着剤等によって貼着させる。
【００４３】
同様に、図４（ｂ）〜（ｃ）に示すように、折り目２５に沿って右側板２９及び蓋用フラップ板３７を内側、即ち底板側に折り曲げ、左側板２８及び蓋用フラップ板３６に重ねて折り畳む。そして、そのとき一緒に折られる各連結板３１，３３の固定部４９を前側板２６及び背側板２７の重なり合った部分に接着剤等によって貼着させる。
【００４４】
このように各連結板３０，３１，３２，３３の固定部４９を前側板及び背側板２７の重なり合った部分に貼着させたことにより、前側板２６及び背側板２７を立ち上げると貼着された連結板３０，３１，３２，３３に連動して左側板２８、右側板２９も立ち上がるようになっている。
【００４５】
そして、図４（ｃ）〜（ｄ）に示すように、押さえ板３９を前上縁板３８の両縁を折り目として折り曲げ、前側板２６に重ね合わせ、重なり合った押さえ板３９の接着片３９ａを前側板２６の内側面を貼着させ、押さえ板４１を同様に背上縁板４０の両縁部を折り目として折り、背側板２７に重ね合わせ、重なり合った押さえ板４１の接着片４１ａを背側板２７の内側面に貼着させる。
【００４６】
これで一次組立が終了し、組立中間部材５１が形成され、この状態で、運搬や保管等を行えば、平板状であるので重ねても嵩張らず効率がよい。
【００４７】
次に、この組立中間部材５１を図５（ｅ）〜（ｆ）に示すように、前側板２６及び背側板２７を立ち上げると、各連結板３０，３１，３２，３３が連動して、蓋用フラップ板３６，３７がそれぞれ一体に形成された左側板２８及び右側板２９も立ち上がる。このとき逃がし片部４３，４３…を立ち上げることにより、連結板３０，３１，３２，３３が前押さえ板３９，４１に邪魔されずに好適に作動する。
【００４８】
そして、図５（ｆ）〜（ｇ）に示すように、各側板２６，２７，２８，２９を底板２１に対して直角に立ち上げ、逃がし片部４３，４３を元に戻して、前押さえ板３９，４１各側縁の係合突起４４，４４を左側板２８及び右側板２９の係止孔４５，４５に係合させ、連結板３０，３１，３２，３３の固定部４９と可動部５０とが重なり合った部分を、前側板２６と押さえ板３９との間、或いは背側板２７と押さえ板４１との間で挟持する。
【００４９】
これで、箱の上面に開閉可能な蓋部を備えた組立式箱２０が形成される。
【００５０】
そして、この箱２０に野菜等の収容物を納めた後、図５（ｇ）〜（ｈ）に示すように、折り目３４，３５より蓋用フラップ板３６，３７を内側に折り曲げて蓋し、蓋用フラップ板３６，３７の側辺に設けられた係止片４６，４６を前側板及び背側板の上縁の係止孔４７，４７に係合させることによって、ホッチキス形の止め金具や粘着テープ等を用いずに閉じることができる。
【００５１】
また、蓋部は、係止片４６，４６を前側板及び背側板の上縁の係止孔４７，４７から外すことで箱の外観を損なうことなく綺麗に開くことができる。
【００５２】
この組立式箱２０を分解する際には、蓋部を開いた状態で、逃がし片部４３，４３を立ち上げ、そのまま前側板２６及び背側板２７を寝かせると、各連結板３０，３１，３２，３３に連動して蓋用フラップ板３６，３７がそれぞれ一体に形成された左側板２８及び右側板２９も寝るので、一次組立が終了したときと同じ状態になる。
【００５３】
尚、上述の実施例では、蓋用フラップ板３６，３７を箱上面中央部において突き合わせる形状のものについて説明したが、両蓋用フラップ板３６，３７の縁部間に隙間を設け、外部から空気を取り込めるようにしてもよい。
【００５４】
また、野菜等の収容物が箱の中に入りきらずに蓋用フラップ板３６，３７が浮き上がってしまい、係止片４６，４６を前側板２６及び背側板２７の上縁に形成された係止孔４７，４７に係合させることができず、蓋を閉じることができない場合がある。
【００５５】
このような場合には、図６に示すように、両蓋用フラップ板３６，３７の突き合わせ側縁部間の間隙を跨いで蓋用補助板６０を上から被せ、その状態で蓋用補助板６０の縁部に形成された取付用係止片６１，６１…を前側板２６及び背側板２７の上縁部、即ち上縁板の部分に形成された係止孔４７，４７に係合させることによって、蓋用補助板６０で両蓋用フラップ板３６，３７を押さえ、蓋用フラップ板３６，３７がそれ以上開かないようにする、即ち箱の上部を閉鎖することができる。
【００５６】
この蓋用補助板６０は、図７に示すように、上述の組立式箱２０と同一の材料を用いて平板状に形成され、縁部に取付用係止片６１，６１…が折り目を介して一体に形成されている。
【００５７】
取付用係止片６１は、鈎状に形成され、蓋用補助板６０が浮き上がった蓋用フラップ板３６，３７に重ねられた状態でも係止孔４７に挿入され係合させることができるように形成されている。
【００５８】
更に、この蓋用補助板６０の裏面、即ち蓋用フラップ板側面には、両面粘着テープ等の貼着手段６２が設けられ、該貼着手段６２を介して蓋用補助板６０の両端部をそれぞれ蓋用フラップ板３６，３７に固定することによって、蓋用フラップ板３６，３７がそれ以上開かないようにしている。
【００５９】
尚、貼着手段６２は、必ずしも用いる必要はなく、取付用係止片６１，６１だけを用いても良い。
【００６０】
上述の実施例では、押さえ板側縁に設けた係合突起４４，４４を左側板２８及び右側版２９に形成された係止孔４５，４５に係合させることにより、押さえ板が左側板２８及び右側板２９に対して係止されるようにした例について説明したが、図８に示すように、逃がし片部４３，４３の上縁板３８，４０とは反対側の縁部に折り目を介して係合突起７０，７０を設け、この係合突起７０を各連結板３０〜３３に係合させることにより、押さえ板３９，４１を前側板２６及び背側板２７に対して係止させるようにしてもよい。
【００６１】
この係合突起７０は、図９に示すように、両側縁に鈎部７０ａ，７０ａが突出した形状に形成されている。
【００６２】
一方、各連結板３０〜３３の固定部４９及び可動部５０には、それぞれ折り目４８を介して対称な位置に係合突起７０が挿入される係止孔７１，７２が形成され、前側板２６、背側板２７には、重ねられる連結板３０〜３３の係止孔７１，７２の位置に合わせて逃げ用凹部７３が形成されている。
【００６３】
可動部側係止孔７１は、係合突起７０の最大幅Ｈより短く、最小幅ｈより長く形成され、固定部側係止孔７２は、係合突起７０の最大幅Ｈと略同じ長さに形成されている。また、可動部側係止孔７１の両端には切れ目７４が設けられている。
【００６４】
各側板２６〜２９を立ち上げると、連結板３０〜３３の固定部４９と可動部５０とが重ね合わされ、可動部側係止孔７１、固定部側係止孔７２及び逃げ用凹部７３が重なった状態となる。
【００６５】
そして、係合突起７０を折り目より折り曲げ、鈎部７０ａで切れ目７４を押し広げながら可動部側係止孔７１及び固定部側係止孔７２に貫通させて挿入すると、切れ目７４が係合突起７０の挿入完了とともに元の状態に回復し、この切れ目７４の内側に係合突起７０の鈎部７０ａが当接されることにより抜け止めされる。このようにして、逃がし片部４３，４３が連結板３０〜３３に対して係着され、側板を押し広げようとする力に対して十分な強度が得られるようになっている。
【００６６】
尚、係合突起７０は、図１０に示すように、矩形状に形成してもよい。この場合、可動部側係止孔７１及び固定部側係止孔７２は、係合突起７０の幅と略同じ長さに形成され、可動部側係止孔には切れ目７４を設けないでよい。
【００６７】
また、上述の実施例では、逃がし片部４３の側縁か、上縁板とは反対側の縁部のいずれかに係合突起４４又は係合突起７０を設けた例について説明したが、両箇所にそれぞれ係合突起４４，係合突起７０を設けるようにしてもよい。
【００６８】
【発明の効果】
上述のように、本発明に係る組立式箱は、ホッチキス形の止め金具や粘着テープ等を用いずに、上面に開閉可能な蓋部を備えた箱状に簡単に組み立てることができ、また、組み立てた状態からの分解も容易に行うことができるので、箱の組立作業或いは分解作業の作業効率を向上させ、コストの削減を図ることができる。
【００６９】
また、粘着テープ等を使用しないため、解体しても外観を損なわず、再利用を図ることができる。
【００７０】
更に、底部が周壁と一体化した一枚の底板からなっているので十分な強度を確保することができ、底抜けに対する十分な耐力を備える。
【００７１】
また、蓋用フラップ板に係止片を備え、前側板及び背側板の係止孔に着脱可能に係止させることによって、粘着テープやホッチキス形の止め金具等を用いずに、好適に蓋部を閉じた状態にすることができる。
【００７２】
更に、蓋用補助板を用いることによって、箱内に収容物が収まりきらず、蓋用フラップ板が浮き上がってしまった場合でも、好適に箱上部を閉鎖すること、即ち蓋をすることができる。
【００７３】
押さえ板を、前側板及び背側板の内側面上端部のみに重なるようにしたことによって、箱高さが高いものであっても、材料、即ち展開された板状材の面積が少なく済み経済的である。
