Description

【０００１】
【発明の属する技術の分野】
本発明は主にストレッチブローとかインデクションブローとか、一般的にはペット樹脂ブローなどと呼ばれているブロー成型方法などで造形されたジュースやミネラルウォーターの容器であって、特に飲み干された時その長さ方向が縮小（容積が縮小）できるようにした容器とその縮小方法に関する。
【０００２】
【従来の技術】
合成樹脂ボトルの生産量は、近年膨大なものになっている。しかし、容器本体内のジュースやミネラルウオーターを飲み干して、該容器本体を破棄する時飲み干す以前の形状の儘であり、これを所謂ゴミ箱に破棄する場合は、まるで空気をゴミ箱に捨てたような状態ですぐ満杯となり、あげくは路上に破棄され、生活環境を悪化させる最大の欠点があり、加えてそれは、飲み干された容器本体の回収費や、清掃の為の人件費は公共事業の大きな負担となっているのである。
【０００３】
またこの種合成樹脂ボトルは、それをブロー成型など手軽な手段で製造できる反面、激しい振動を伴う自動車やその他の搬送手段や、積み重ねられる店頭での展示にあったその強度が未だ充分とは言えないものがあった。
【０００４】
さらにこの事は、容器を製造する業者からジュースやミネラルウオーターを封入する会社に搬送する際も、当該容器本体が嵩ばってまるで空気を搬送しているような状態で、製品の搬送費にかかる割合は相当なものとなっていたのである。
【０００５】
そこで本願発明者は先に液体容器の廃品を回収するに当たって、その容器を簡単に縮小することができるように工夫した液体容器を提供した。これは比較的軟質の合成樹脂で作られ、上端に口部をもった液体容器本体の周壁を蛇腹状としたことである。（特許文献１）
【０００６】
また、これに加え容器本体の垂直方向及び／あるいは捩り方向に負荷を与えることによって、実質的にその容積が縮小するような形状としたこと、およびこの縮小された形状を保持する手段と容器本体の発明（特許文献２）を提唱したが、いずれも上記目的即ち容器本体を押し潰した際未だその高さ、及び容器をより縮小させその状態を保たさせるに充分対処でき得なかった。

【発明が解決しようとする課題】
総じて本発明の目的は、容器本体内のジュースやミネラルウオーターを飲み干して、該容器本体を破棄する時、その容積を頗る小さくすることが出来るようにしたことであり、従来空の容器本体をゴミ箱に収容しきれなったのに比し、その収容個数を従来の商品と比べさらに頗る増大させたことであり、このことは同時に空の容器本体の搬送を同時に多量に成し得るから、その回収費や清掃回収の為の人件費を、頗る軽減させ得うるようにしたことである。
【０００９】
続いて、容器を製造する業者から、ジュースやミネラルウオーターを封入する会社に搬送する際も、一度の搬送量を従来の量との比較において、さらに著しく増大させたことも本発明の目的である。
【００１０】
また本発明の目的は上記のように、飲干された容器を破棄する時、あるいは搬送する時、その容積を頗る小さくすることが出来るようにしたことであるが、その状態は容器本体に復元力を与えることなく、長時間，あるいは長期間，若しくは再利用の為の粉砕や溶解などの作業時まで、その縮小された形状を保つようにしたことである。
【００１１】
なお、本発明の容器本体の全体形状は、楕円を含む円柱，矩形を含む角柱，截頭を含む円錐および角錐から適宜選ばれるものであり、同水平断面形状を、楕円を含む丸形，矩形を含む角形から適宜選ばれるようにしたことである。
【００１２】
他に本発明の目的は、容器内容物の案内や商標などが印刷されたレッテルを、巻装したり直接容器本体に印刷等成す時、従来のものに比してその面積を大きくすることが出来るようにしたことである。
【００１３】
なお、本発明の容器本体はこれを飲料容器として使用する時、その外観の形状の見栄えがよく、使用する者に多大な興味を持たせかつ、使用中に容器本体が滑り落ちたり、あるいは内容物を溢出させたりする虞も未然に防止できるのであって、この為には長さ方向が縮小された状態を保つことが可能な容器を提供し、その縮小方法を提唱するものである。
【００１４】
【課題を解決するための手段】
本発明の特徴は、上端部の飲み口部と、底部の小さい高さ方向の幅と、この飲み口部と高さ方向の幅とを除いて長手方向の全部或いは一部が水平方向の蛇腹状となっている容器本体で構成されていることである。
【００１５】
而して上記容器の蛇腹部分が、その長手方向の両方から中心方向に押し圧された際、上記蛇腹部分が重なり合った潰された状態となり，上端部の飲み口部と容器本体の連結部分は折曲がって、重なった蛇腹状部分内に位置させ、この状態を保つようにしたことである。
【００１６】
他に本発明の特徴は、上端部の飲み口部と、底部の小さい高さ方向の幅と、中間部に設けたフラット部とを有し、この飲み口部と高さ方向の幅とフラット部とを除いて長手方向の全部或いは一部が水平方向の蛇腹状となっている容器本体で構成されていることである。
【００１７】
而して上記容器の蛇腹部分が、その長手方向の両方から中心方向に押し圧された際、上記蛇腹状部分が重なりあった潰された状態となり、かつ上端部の飲み口部と容器本体の連結部分は折曲って、重なった蛇腹状部分内ａｎｄ／ｏｒフラット部内に飲み口部を位置させ、また、容器本体の底部の高さ方向の幅部分も、折曲がって重なった蛇腹状部分内ａｎｄ／ｏｒフラット部内に位置させ、この状態を保つようにしたことである。
【００１８】
なお上記容器本体の蛇腹状部の形状は、その一方の径が他方の径より小さく他方に行くに従い順次径を拡大させ、下方の径と同等になすようにしたことも、さらに、長さ方向が縮小された状態を保つことが可能な容器の縮小方法であって、上記容器本体の蛇腹状部にそのほぼ直角方向から力を加え、蛇腹状を構成する襞の一片ｏｒ／ａｎｄ一部の内周を一方方向に押す力を与え、その結果外周にはこれと反対方向の力が働き、長さ方向が縮小された蛇腹状を保つようにしたことも本発明の技術的範疇にあるものと考える。
【００１９】
また上記容器本体の全体形状は、楕円を含む円柱，矩形を含む角柱，截頭を含む円錐および角錐，鼓（ＨＯＵＲＧＬＡＳＳＤＲＡＭ−ＳＨＡＰＥＤ），樽形から適宜選ばれるようにしたことも、上記容器本体の水平断面形状を、楕円を含む丸形，矩形を含む角形から適宜選ばれるようにしたことも、上記容器本体の外周に、容器内容物の案内や商標などが印刷されたレッテルを巻装させたことも本発明の技術的な範疇であるものと考える。
【００２０】
さらに上端の中央部より上方に突出させて飲み口部分を設けた容器本体と、上記飲み口部分除きかつ、その長さ（高さ）方向の全長或いは一部で、容器本体の内外壁に形成させた水平方向の蛇腹状と、該蛇腹状部はその上方の径が下方の径より小さく、下方へ行くに従い順次径を拡大させるようにしたもので、上記容器本体の蛇腹状部にそのほぼ直角方向からの力が加わった際、上方の蛇腹状部襞の内径方向は下方に、外径方向は上方に力が働き、下方の蛇腹状部襞の内径方向は上方に、外径方向は上下方に力が働き、上記容器本体の長さ（高さ）が縮小された蛇腹状を保たれるようになしたこと及び、仮令えばジュースを一部飲んだのち携行あるいは保有する場合、その飲み量に応じた分だけ容器本体を縮小させることができるので、その携行あるいは保存の容積をその分だけ少なくすることができるようにした点も本発明の技術的範疇にある。
【００２１】
なお本発明にはその他に優れた発明の目的、特徴、作用効果を有するが、これらは以下の実施例の説明で明らかにする。
【００２２】
【発明の実施の形態】
以下、図面に基づいて本発明の実施形態を説明する。
【００２３】
図１で（１）は容器本体で、その高さ（長さ）方向の外周と内周は蛇腹状（２）となっている。
【００２４】
（実施の形態１）
図３，図６では上記容器本体（１）内の仮令えばミネラルウォータを飲み干してから高さ（長さ）方向にその一方からあるいは両方から押し潰した状態を示した。即ち本発明はこのような容器本体（１）を押し潰した状態とするため及び潰れた状態を保つため秀れた構成を有し、秀れた作用を発揮するのである。
【００２５】
その容器の構成の一例として図１１でわかるように（３）は、その外周に雄ねじを刻設した容器本体（１）の直径約２８ｍｍ，高さ２３ｍｍ程度の飲み口部で、その直下方は下方が直径約５１ｍｍ，に拡大された高さ５〜１０ｍｍの喇叭状連結部（Ｄ）が、飲み口部（３）の軸線上に接続されている。上記容器本体（１）の肩部（Ｃ）にはその内端が水平な『Ｕ』字状の環状溝（Ｅ）があり、上記喇叭状連結部（Ｄ）の末端と環状溝（Ｅ）の内側の辺とは連結している。またＵ字形状の溝（Ｅ）の外側の辺は下方に向う割球状（４）となっており、第１段の蛇腹状（５）の外径（ｄ１）、即ち上記蛇腹状（２）の最上段の外径（ｄ１）は、容器本体（１）の外径（ｄ）より小さい径とする。続いて第１段の蛇腹状（５）に対し第２段の蛇腹状（６）外径の（ｄ２）は、上記第１段の蛇腹状（５）の外径（ｄ１）より大きく容器本体（１）の外径（ｄ）より小さい。
【００２６】
さらにこれと連なりかつ上記第２段の蛇腹状（６）の外径（ｄ２）より大きく容器本体（１）の外径（ｄ）より小さい第３段の蛇腹状（７）の外径（ｄ３）となるように側面からみて階段状となっているが、勿論これは上記のように３段とすることに限らず適宜の複数段でもよいが図の実施例では３段とした。
【００２７】
具体的に図１の容器は高さ１９５ｍｍ×最大直径７１．５ｍｍ，容
量５００ｍｌの容器本体（１）にあって、１２段の壁を有する形状とした。
【００２８】
但しこの場合第１段の蛇腹状（５）の外径（ｄ１）は３０．２５ｍｍ，第２段の蛇腹状（６）の外径（ｄ２）は３３．９５ｍｍであり、これら第１段の蛇腹状（５）と第２段の蛇腹状（６）の間の内径は、４７ｍｍとした。
【００２９】
これと同様、第３段の蛇腹状（７）の外径（ｄ３）は３４．８５ｍｍであり、第２段の蛇腹状（６）と第３段の蛇腹状（７）の間の内径は５１．１ｍｍとした。さらに第４段の蛇腹状（８）の外径（ｄ）は上記容器本体（１）の最大外径である径は３５．７５ｍｍであり、第３段の蛇腹状（７）と第４段の蛇腹状（８）の間の内径は５４．５ｍｍとした。また以下の第５段乃至第１２段の蛇腹状の外径は第４段の蛇腹状（８）の外径（ｄ）と同じであり、それぞれの間の内径もまた上記第３段の蛇腹状（７）と第４段の蛇腹状（８）との間のそれと同一である。
【００３０】
この場合上記各襞は、アダムスキー（Ａｄａｍｓｋｉ）型と呼ばれる未確認飛行物体（ＵＦＯ）のような形状をしており、従って水平方向の上下に２分される。この時図で上記第１段の襞の上（ｈ１）：下（ｈ２）の高さは６．５ｍｍ：５．５ｍｍ，第２段の襞のそれは７ｍｍ：５ｍｍ，第３段の襞のそれは８．５ｍｍ：６．５ｍｍとなした。
【００３１】
より具体的にこれら襞の断面形状を図１３で示している。すなわちこれは上記第１段（５）乃至３段（７）の襞の寸法の例であるが、同図で巾広のそろばん球形状の上面（２０）の形状は、外方向に突出したこの実施例では２０ｍｍＲの湾状（９）となっており、これに対して下面（２１）は０．８ｍｍＲの突出弧状（１０）を介して直線状（１１）となっていることが重要なポイントである。
【００３２】
この実施の形態のこの構成をその作用と併せて説明すると、概略上記図１の状態の容器本体（１）は、中央部及び下部を含む胴部（Ａ）と上方の肩部（Ｃ）に２分され、それぞれの部位（Ａ）（Ｃ）は、それぞれの比較に於いて、その径が大径と小径の２つの径からなっていることから、安定した垂直状態を保っている。
【００３３】
即ち上記中央部と下部を含む胴部（Ａ）は内外径が同一の襞で形成され、肩部（Ｃ）は外観的に飲み口部（３）方向が緩傾斜の凸状に湾曲され、特にこの肩部（Ｃ）は中央部から飲み口部（３）までの間で、襞を形成する谷（１８）の内径を徐々に減少させると共に、その傾斜角度も胴部（Ａ）より差を大きくしたから、この中央部が伸張している状態にあっては襞を形成する山（１７），谷（１８）の内径及び傾斜面は材料の持つ強度と弾性で伸長・伸展状態を保つことができるのである。なお底面（Ｂ）を急傾斜の凹状とすることで所謂「すわり」がよくなること当然である。
【００３４】
さて、容器本体（１）のキャップ（１４）を取外し、内容物を飲み干し容器本体（１）を図３のように両手（Ｇ）（Ｈ）の平（ひら）間に垂直に置き、容器本体（１）の中間方向に、両手（Ｇ）（Ｈ）で押圧すると、図４のように容器本体（１）は押し潰されたような状態となる。
【００３５】
ここで上記押圧するに必要な強い力があればよいが、多くの場合両手の人差し指から小指までを容器本体（１）の底面部（Ｂ）に添わせ、両方の手（Ｇ）（Ｈ）のそれぞれの親指を飲み口部（３）の上図に添わせ、それぞれの指を容器本体（１）の中心方向に押圧すると、図５のように飲み口（３）は容器本体（１）内に埋没するようになる。
【００３６】
この状態に於ける容器本体（１）の上部及び下部を含む胴部（Ａ）は図１１から図１６に示すように、肩部（Ｃ）や胴部（Ａ）が圧縮されて縮んだ状態となる。即ち図１４で示す状態から肩部（Ｃ）の襞を押圧し、谷（１８）の端面が上下の関係で隣に位置する襞の谷端面を圧縮することになる。この時点で襞の山（１７）の頂点からみた状態では、図１５，１６のように両側の谷（１８）がこの山（１７）の頂点側に押し寄せられたことに相当しこの際、襞の上面（２０）は下面（２１）に対して緩傾斜側の圧縮分力は傾斜が少ない為に下面（２１）の急傾斜側の圧縮分力より大きいことから急傾斜側の谷（１８）が山（１７）部の頂点側に移動したことになる。
【００３７】
この時容器本体（１）には２つの大きな変化が生じている。即ちその第１は、上記襞を構成する山（１７）部の内径が拡大圧力で増加、あるいは谷（１８）の内径が圧縮圧力で減少すること、その第２は、襞を構成する下面（２１）の急傾斜面が屈曲することである。
【００３８】
続いてこの急傾斜側が山（１７）部直下を通過して、さらに図１６でみられるように上面（２０）の緩傾斜側の内側に潜り込んで、容器本体（１）の高さを短縮状態まで移動させると、山（１７）の内径及び谷（１８）の内径が復元する力が働き、または下面（２１）が上記の操作で屈曲状態となっていたものを伸展状態に復元して安心した状態となる。従って常に圧縮力を加えておかなくとも、この短縮状態を保つようになることができたのである。
【００３９】
そして内径の小さい谷（１８）は圧縮圧力を受けて、さらに内径が小さくなり、圧力応力が発生している。圧縮圧力が無くなると応力が開放されるように作用し、伸長状態に復元する。そして圧力状態でキャップ（１４）を締め、大気圧を作用させると容器本体（１）は短縮状態を保持し、谷（１８）の内径の差によって圧縮応力が発生しない場合には短縮状態を保持することとなるのである。
【００４０】
この結果容器本体（１）は度重なる実験では、その高さ（容積）が１／３乃至１／４以下となり、これをゴミ箱などに放棄してもそのスペースを格段に少なくすることができたのである。
【００４１】
本発明では、この状態になった後も更に飲み口部（３）を、容器本体（１）の底面（Ｂ）方向に押圧する。このとき容器本体（１）の胴部（Ａ）及び肩部（Ｃ）はそれぞれの襞が密着して折り重なっているため、これ以上押し上げても下降しない。ここでさらに飲み口部（３）を下方に押圧すると、先ず喇叭状の連絡部（Ｄ）の末端辺がＵ字形状の溝（Ｅ）の内側を下方に押圧する。この結果かかる溝（Ｅ）はその外側上端の辺と、肩部（Ｃ）とが連結され固着された状態となっているから、そのＵ字形状が崩れ内側が下方に押された状態で、喇叭状連絡部（Ｄ）の末端部を下方に押圧しつつ拡大する方向に進み、ついには図４に示すように容器本体（１）内に飲み口部（３）と共に押し込まれる状態となるのである。
【００４２】
上記この実施の形態では飲み口部（３）と容器本体（１）の間の連結部（Ｄ）を喇叭状となし、これを潰したとき反転させて容器本体（１）内に嵌入させるようにした。
【００４３】
しかし、飲み口（３）は無理に潰された容器本体（１）内に押し込まなくとも充分にその高さ（即ち容積）を縮小することができる。これを図１で説明すると、容器本体（１）の襞は巾広のＡｄａｍｓｋｉ型のＵＦＯのような形状をしており、従って水平方向の上下に２分される。この時図１で上記第１段の襞の上（ｈ１）下（ｈ２）の高さは６．５ｍｍ：５．５ｍｍ，第２段の襞のそれは７ｍｍ：５ｍｍ，第３段の襞のそれは８．５ｍｍ：６．５ｍｍとなした。
【００４４】
さらに第４段の蛇腹状（８）乃至１２段の蛇腹状の襞の寸法及び襞の上（ｈｘ）下襞の上（ｈｙ）の高さその形状は格段共通なものとなっている。
【００４５】
即ち図において（２０）は巾広のＡｄａｍｓｋｉ型のＵＦＯ形状の内面も含む上面であり、（２１）は巾広のＡｄａｍｓｋｉ型のＵＦＯ形状の内面も含む下面であるが、上面（２０）の形状は外方向に突出したこの実施例では２０ｍｍＲの湾状（９）となっており、これに対して下面（２１）の形状は０．８ｍｍＲの突出弧状（１０）を介して直線状（１１）となっていることが重要なポイントである。
【００４６】
そして内径の小さな谷（１８）は圧縮圧力を受けて圧力応力が発生している。圧縮圧力が無くなると応力が開放されるように作用し、伸長状態に復元する。そして圧力状態でキャップ（１４）を締め、大気圧を作用させると容器本体（１）は短縮状態を保持し、谷（１８）の内径の差によって圧縮応力が発生しない場合には短縮状態を保持することとなるのである。
【００４７】
この実施例は前記のように容器本体（１）の肩部（Ｃ）の襞の径が下方に向うに従い大径とした場合で、その結果押し潰された各襞はその外周辺が内周辺に対して上方となる傾斜上に重ね合わせられる。
【００４８】
その後飲み口部（３）の上面部ａｎｄ／ｏｒ肩部の割球状（４）を押圧すると、その押し下げる力は図１１のように各襞の外周辺にも押し下げる力（Ｆ１）が働き、その結果図１１に示すように中央部及び下部を含む胴部（Ａ）の壁は、その外周辺が内周辺に対して下方となる上記肩部（Ｃ）とは逆方向の傾斜状に重ね合わせられる。
【００４９】
而してこの押し潰された容器本体（１）にあって肩部（Ｃ）の襞の上方の傾斜部を形成する割球状（４）及び湾状（９）と、胴部（Ａ）の襞の下方の傾斜部が所謂「つりあって」容器本体（１）はキャップ（１４）を再び被冠させなくとも潰された状態を保つことができるようになる所以である。
【００５０】
この結果容器本体（１）は度重なる実験では、その高さ（容積）が１／３乃至１／４以下となり、これをゴミ箱などに放棄してもそのスペースを格段に少なくすることができたのである。
【００５１】
さらに上述したように本発明の実施例では飲み口部（３）を押圧することで、該飲み口部（３）を容器本体（１）内に埋入させ、同時に容器本体（１）の底部（Ｂ）周辺も上記容器本体（１）の肩部（Ｃ）を反転させたのと同等の作用で容器本体（１）内に埋入させたから、結果空の容器本体（１）をそのまま捨てる部分に比べその容積（高さ）を１／５程度にコンパクト化することができたのである。
【００５２】
また、飲用容器として通常出廻っている商品は５００ｍｌであるから、一度にこれを「飲み干す」ことはほとんどない。従って、飲み残しがあっても容積はそのままの空の部分がある容器を携行しなくてはならない。その点本発明の容器は飲み干されて空となった部分を縮めて携行できるようにしたから、ハンドバックの中でも容易に収容できるのである。
【００５３】
なお力の比較的弱い子供や女性の場合は、この容器本体（１）を押し潰す作用を「手」だけに頼るだけでなく、図７のように足で踏みつけると極く容易に潰せるのである。
【００５４】
さらに多くの飲料容器に用いられるペットボトルはその商標や内容の説明あるいは出所を表す表示のフラットな掲載部分（Ｊ）が容器本体（１）の中間部に設けられるが、これは図８乃至図１０に示した。
【００５５】
この容器で内容物を飲み干した空の容器本体（１）を押し潰す作用は、前記と同様であるので、その詳細な説明を省くが、上記掲載部分（Ｊ）は、容器本体（１）の中間部にあってその内径が容器本体（１）の蛇腹状部（２）の外径と略等しく造形され、この為容器本体（１）をその上下方向から押し潰すとその飲み口部（３）も底面（Ｂ）及び周辺も掲載部分（Ｊ）に押し込まれて体裁のよい形崩れしない状態で押し潰し状態が保たれ、このことはこれをクズ籠などに捨てるときその収容量を大巾に増しかつ、捨てられた状態も見栄えがよい。
【００５６】
（他の実施の形態）
上記の実施の形態では容器本体（１）の外観断面形状を円筒またはそれに近いものとした。しかし縦長手方向の形状を鼓状とすると握り易く、また図２０のように円錘台形状（Ｋ）や角錘台形状にしたら安定がよく、これらの外観的な形状では適宜の形状から任意のものを選ぶことができる。
【００５７】
また容器本体（１）にあってその上記表示掲載部分（Ｊ）は図２１のように容器本体（１）の下部のみ、あるいは図２２のように上部のみ、または図２３のように面方に設けてもよい。
【００５８】
さらに上記の実施の形態では、容器本体（１）に形成させた蛇腹状（２）の形状を水平な上下方向に連続した環状の襞状とした。
【００５９】
しかし、この形成を連続するスパイラル形状とすることによって、これを潰す場合容器本体（１）の上方あるいは中央に向かって上下方向からの押圧力に加え捻りの力が加わり、より容易に潰せることが判明した。なおこのスパイラル形状は一条のものでなく数条のものでよい。
【００６０】
【発明の効果】
以上述べた本発明の主な効果は、容器本体を破棄する時、その容積を頗る小さくすることが出来るようにしたことであり、ゴミ箱などに収容できる個数を頗る増大させたことである。
【００６１】
またかかる縮小させた容器本体は、その搬送量を同時に多量に成しできるから、その回収費や清掃回収の為の人件費を、頗る軽減できたことである。
【００６２】
さらに本発明の容器本体は、その外観の形状の見栄えがよく、使用する者に多大な興味を持たせかつ、容器本体の蛇腹の形状が摩擦止めとなり、使用中に容器本体が滑り落下させたり、あるいは内容物を溢出させたりする虞も未然に防止できるのである。
【００６３】
また本発明によって潰された状態の容器本体といえどもその形状は意匠的に見栄えのよいもので、そのまま外の容器としても利用できるのである。

TECHNICAL FIELD OF THE INVENTION
The present invention is mainly a container for juice or mineral water formed by a blow molding method such as a stretch blow, an injection blow, or a pet resin blow, and particularly when the drink is dried up. The present invention relates to a container whose length direction can be reduced (reduced in volume) and a method of reducing the container.
[0002]
[Prior art]
The production volume of synthetic resin bottles has been enormous in recent years. However, when the juice or mineral water in the container body is swallowed up and the container body is discarded, the shape remains the same as before swallowing. It is quickly filled up and eventually destroyed on the street, which has the biggest disadvantage of deteriorating the living environment. In addition, the cost of collecting the drunk containers and the labor cost for cleaning are a heavy burden on public works. It is.
[0003]
Although this type of synthetic resin bottle can be manufactured by simple means such as blow molding, it can still be said that its strength, which was exhibited in automobiles and other transporting means with severe vibrations and in stores that are stacked, is still insufficient. There was nothing.
[0004]
Furthermore, when transporting from a container manufacturer to a company that encloses juice or mineral water, the cost of transporting the product is increased in a state where the container body is bulky and transports air. The proportion was substantial.
[0005]
Therefore, the inventor of the present application has provided a liquid container devised so as to be able to easily reduce the size of the liquid container before collecting the waste. This means that the peripheral wall of the liquid container body made of a relatively soft synthetic resin and having an opening at the upper end is formed in a bellows shape. (Patent Document 1)
[0006]
Further, in addition to the above, the shape is such that the volume is substantially reduced by applying a load in the vertical direction and / or the torsional direction of the container body, and means for holding the reduced shape and the container body However, none of the above-mentioned inventions (Patent Literature 2) could sufficiently cope with the above-mentioned object, that is, the height of the container body when the container body was crushed, and the reduction of the size of the container to maintain the state.

[Problems to be solved by the invention]
In general, an object of the present invention is to make it possible to drastically reduce the volume of a container body when the juice or mineral water in the container body is drunk up and the container body is discarded. This is because the number of containers that can be stored is greatly increased compared to conventional products, which means that a large number of empty containers can be transported at the same time. The cost and labor cost for cleaning and collection can be greatly reduced.
[0009]
Subsequently, it is also an object of the present invention that, even when transported from a manufacturer of containers to a company that encloses juice or mineral water, the transported amount at one time is significantly increased in comparison with the conventional amount. .
[0010]
Further, as described above, the object of the present invention is to make it possible to greatly reduce the volume of a drunk container when discarding or transporting the container, but the state is restored to the container body. Without applying force, the reduced shape is maintained for a long time, or for a long time, or during operations such as crushing and melting for reuse.
[0011]
The overall shape of the container body of the present invention is appropriately selected from a cylinder including an ellipse, a prism including a rectangle, a cone including a truncated cone, and a pyramid. Is appropriately selected from the squares including.
[0012]
Another object of the present invention is to increase the area of a label printed with a guide or trademark of the contents of a container when the label is wound or printed directly on the main body of the container as compared with a conventional one. It was made possible.
[0013]
When the container body of the present invention is used as a beverage container, the appearance of the container is good in appearance, giving a great interest to the user, and the container body slides down during use, or the contents may be reduced. The possibility of overflowing an object can be prevented beforehand. For this purpose, a container capable of keeping a reduced length is provided, and a method of reducing the size is proposed.
[0014]
[Means for Solving the Problems]
The feature of the present invention is that all or a part of the bellows in the longitudinal direction except for the spout at the upper end, the width in the small height direction at the bottom, and the width in the spout and the height is horizontal. That is, it is constituted by a container main body having a shape.
[0015]
Thus, when the bellows portion of the container is pressed in the center direction from both the longitudinal direction, the bellows portion overlaps and is in a crushed state, and the connecting portion between the drinking spout at the upper end and the container body is formed. That is, it is located in the folded and overlapping bellows-like portion, and this state is maintained.
[0016]
Other features of the present invention include a spout at the upper end, a small height width at the bottom, and a flat portion provided at an intermediate portion. Except for the part, the whole or a part in the longitudinal direction is constituted by a container main body having a horizontal bellows shape.
[0017]
Thus, when the bellows portion of the container is pressed in the center direction from both the longitudinal direction thereof, the bellows-like portion is in a crushed state overlapping with each other, and the drinking part at the upper end and the container body are The connecting portion is bent so that the drinking spout is located in the overlapped bellows-like portion and / or the flat portion, and the width portion in the height direction of the bottom of the container body is also bent inside the folded bellows-like portion. and / or in a flat portion to maintain this state.
[0018]
In addition, the shape of the bellows-like portion of the container body may be such that one of the diameters is smaller than the other and the diameter is sequentially increased as going to the other, so as to be equal to the diameter of the lower part, and further, the length direction. Is a method of reducing a container capable of maintaining a reduced state, wherein a force is applied to the bellows-like portion of the container main body from a direction substantially perpendicular to the bellows-like portion, and a part or / and a part of a fold constituting the bellows-like portion is applied. It is also within the technical scope of the present invention to apply a force that pushes the inner circumference in one direction, and as a result, a force in the opposite direction acts on the outer circumference to maintain a bellows shape with its length reduced. Think.
[0019]
The overall shape of the container body may be appropriately selected from a cylinder including an ellipse, a prism including a rectangle, a cone and a pyramid including a truncated cone, a drum (HOURGLASS DRAM-SHAPED), and a barrel shape. The horizontal cross-sectional shape of the container may be appropriately selected from a round shape including an ellipse and a square shape including a rectangle. Alternatively, a label printed with a guide or a trademark of the contents of the container may be wound around the outer periphery of the container body. This is also considered to be a technical category of the present invention.
[0020]
Further, a container body protruding upward from the central portion of the upper end and having a spout portion is formed on the inner and outer walls of the container body, excluding the spout portion and the entire length or a part of the length (height) direction thereof. The horizontal bellows shape and the bellows-like portion whose upper diameter is smaller than the lower diameter and whose diameter gradually increases as going downward, the bellows-like portion of the container body has almost When a force is applied from a right angle direction, a force acts downward in the inner diameter direction of the upper bellows-shaped fold and upward in the outer diameter direction, and upwards in the inner diameter direction of the lower bellows-shaped fold, and in the outer diameter direction. The upper and lower forces act to keep the length (height) of the above-mentioned container body in a reduced bellows shape. Since the container body can be reduced by the amount corresponding to the amount of drink, Point where the lines or storage volume to be able to minimize that amount also in the technical scope of the present invention.
[0021]
The present invention has other excellent objects, features, and operational effects, which will be clarified in the description of the following embodiments.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0023]
In FIG. 1, (1) is a container body, and the outer periphery and the inner periphery in the height (length) direction are bellows-like (2).
[0024]
(Embodiment 1)
FIGS. 3 and 6 show a state in which the mineral water in the container body (1), for example, the mineral water is drunk up and then crushed from one or both in the height (length) direction. That is, the present invention has an excellent structure for bringing such a container body (1) into a crushed state and maintaining the crushed state, and exhibits an excellent action.
[0025]
As can be seen from FIG. 11 as an example of the configuration of the container, (3) is a drinking mouth part having a diameter of about 28 mm and a height of about 23 mm of a container body (1) having an external thread engraved on the outer periphery thereof, and a portion directly below the drinking part. A lozenge-shaped connecting part (D) having a height of 5 to 10 mm and an enlarged diameter of about 51 mm at the lower part is connected to the axis of the spout (3). The shoulder (C) of the container body (1) has a horizontal U-shaped groove (E) at its inner end, and the end of the horn-shaped connection (D) and the ring groove (E). Is connected to the inner side of. The outer side of the U-shaped groove (E) has a split spherical shape (4) directed downward, and the outer diameter (d1) of the first-stage bellows-like shape (5), that is, the above-mentioned bellows-like shape (2) Is smaller than the outer diameter (d) of the container body (1). Subsequently, the outer diameter (d2) of the second-stage bellows (6) is larger than the outer diameter (d1) of the first-stage bellows (5) with respect to the first-stage bellows (5). It is smaller than the outer diameter (d) of (1).
[0026]
Further, the outer diameter (d3) of the third-stage bellows (7) that is larger than the outer diameter (d2) of the second-stage bellows (6) and smaller than the outer diameter (d) of the container body (1). ) Is a step-like shape as viewed from the side. Of course, the number is not limited to three as described above, but may be an appropriate plural number. However, in the embodiment shown in FIG.
[0027]
Specifically, the container shown in FIG. 1 is a container body (1) having a height of 195 mm, a maximum diameter of 71.5 mm, and a capacity of 500 ml, and has a shape having 12 steps of walls.
[0028]
However, in this case, the outer diameter (d1) of the first-stage bellows shape (5) is 30.25 mm, and the outer diameter (d2) of the second-stage bellows shape (6) is 33.95 mm. The inner diameter between the bellows shape (5) and the second stage bellows shape (6) was 47 mm.
[0029]
Similarly, the outer diameter (d3) of the third-stage bellows (7) is 34.85 mm, and the inner diameter between the second-stage bellows (6) and the third-stage bellows (7) is 51.1 mm. The outer diameter (d) of the fourth bellows (8) is 35.75 mm, which is the maximum outer diameter of the container body (1). The inner diameter between the bellows-like shapes (8) was 54.5 mm. The outer diameter of the bellows of the following fifth to twelfth stages is the same as the outer diameter (d) of the bellows of the fourth stage (8), and the inner diameter between them is also the above-mentioned bellows of the third stage. It is identical to that between shape (7) and the fourth stage bellows shape (8).
[0030]
In this case, each of the folds is shaped like an unidentified flying object (UFO) called Adamski type, and is therefore divided into upper and lower parts in the horizontal direction. At this time, the height of the upper (h1): lower (h2) of the first fold is 6.5 mm: 5.5 mm, that of the second fold is 7 mm: 5 mm, and that of the third fold is 8.5 mm: 6.5 mm.
[0031]
More specifically, the cross-sectional shapes of these folds are shown in FIG. That is, this is an example of the dimensions of the folds of the first stage (5) to the third stage (7), and the shape of the wide abacus spherical upper surface (20) in FIG. In the embodiment, the shape is a bay shape (9) of 20 mmR, while it is important that the lower surface (21) is linear (11) through a protruding arc shape (10) of 0.8 mmR. It is.
[0032]
This configuration of this embodiment will be described together with its operation. The container body (1) in the state shown in FIG. 1 is roughly provided with a body portion (A) including a central portion and a lower portion and an upper shoulder portion (C). The two parts are divided into two parts, and the respective parts (A) and (C) maintain a stable vertical state because their diameters are composed of two diameters, a large diameter and a small diameter.
[0033]
That is, the body part (A) including the central part and the lower part is formed of the same fold with the same inner and outer diameters, and the shoulder part (C) is outwardly curved so that the direction of the mouth part (3) is slightly inclined, In particular, the shoulder (C) gradually reduces the inner diameter of the valley (18) forming the fold from the center to the spout (3), and its inclination angle is also different from that of the trunk (A). In the state where the central portion is extended, the inner diameter and the inclined surface of the ridges (17) and valleys (18) forming the folds maintain the stretched / extended state due to the strength and elasticity of the material. You can do it. It should be noted that the so-called “seat” is improved by making the bottom surface (B) concavely steep.
[0034]
Now, remove the cap (14) of the container body (1), drink the contents, and place the container body (1) vertically between the flats of both hands (G) and (H) as shown in FIG. When pressed with both hands (G) and (H) in the middle direction of (1), the container body (1) is in a crushed state as shown in FIG.
[0035]
Here, it is sufficient if there is a strong force necessary for the pressing, but in many cases, the forefinger to the little finger of both hands are attached to the bottom portion (B) of the container body (1), and both hands (G) and (H) When each thumb is put on the upper part of the mouth part (3), and each finger is pressed toward the center of the container body (1), the mouth part (3) becomes the container body (1) as shown in FIG. It will be buried inside.
[0036]
In this state, the trunk (A) including the upper and lower parts of the container body (1) is in a state in which the shoulder (C) and the trunk (A) are compressed and contracted, as shown in FIGS. It becomes. That is, the fold of the shoulder (C) is pressed from the state shown in FIG. 14, and the end face of the valley (18) compresses the valley end face of the adjacent fold in a vertical relationship. At this point, when viewed from the top of the ridge (17), the valleys (18) on both sides are pushed toward the top of the ridge (17) as shown in FIGS. The upper surface (20) of the valley (18) on the steeply sloping side is smaller than the lower surface (21) because the compressive component on the gently sloping side is less inclined than the lower surface (21). Has moved to the vertex side of the mountain (17).
[0037]
At this time, two major changes occur in the container body (1). That is, the first is that the inner diameter of the ridge (17) constituting the fold is increased by the expanding pressure, or the inner diameter of the valley (18) is decreased by the compressing pressure, and the second is that the lower surface ( 21) The steeply inclined surface is bent.
[0038]
Subsequently, the steeply sloping side passes directly below the mountain (17), and further sinks into the inside of the upper surface (20) on the gentlely sloping side, as shown in FIG. 16, to reduce the height of the container body (1). When it is moved to the maximum, the force that restores the inner diameter of the peak (17) and the inner diameter of the valley (18) works, or the lower surface (21) restores the bent state by the above operation to the extended state, which is safe. It will be in the state of having done. Therefore, it is possible to maintain the shortened state without constantly applying a compressive force.
[0039]
Then, the valley (18) having a small inner diameter receives the compressive pressure, and the inner diameter is further reduced, and pressure stress is generated. When the compression pressure is removed, the stress acts to release the stress and restores the stretched state. When the cap (14) is tightened under pressure and atmospheric pressure is applied, the container body (1) maintains the shortened state, and when the compressive stress is not generated due to the difference in the inner diameter of the valley (18), the vessel body (1) is maintained in the shortened state. It will be.
[0040]
As a result, in repeated experiments, the height (volume) of the container body (1) was reduced to 1/3 to 1/4 or less. Even if the container body (1) was discarded in a trash box or the like, the space was significantly reduced. It is.
[0041]
In the present invention, even after this state is reached, the spout (3) is further pressed in the direction of the bottom surface (B) of the container body (1). At this time, since the folds of the body (A) and the shoulder (C) of the container main body (1) are tightly folded and folded, the body (A) and the shoulder (C) do not descend even if pushed further. Here, when the drinking mouth part (3) is further pressed downward, the terminal side of the horn-shaped connecting part (D) first presses the inside of the U-shaped groove (E) downward. As a result, since such a groove (E) is in a state where the side at the outer upper end and the shoulder (C) are connected and fixed, the U-shape is collapsed and the inside is pushed downward. It pushes down on the end of the horn-shaped connecting part (D) and proceeds in the expanding direction, and finally is pushed into the container body (1) together with the spout (3) as shown in FIG. is there.
[0042]
In this embodiment, the connecting portion (D) between the spout portion (3) and the container body (1) is formed in a horn shape, and when it is crushed, it is inverted and fitted into the container body (1). I made it.
[0043]
However, the height (that is, volume) of the drinking spout (3) can be sufficiently reduced without being forced into the crushed container body (1). Referring to FIG. 1, the fold of the container body (1) is shaped like a wide Adamski-type UFO, and is therefore divided into two in the horizontal direction. At this time, in FIG. 1, the height above (h1) and below (h2) above the first fold is 6.5 mm: 5.5 mm, that of the second fold is 7 mm: 5 mm, and that of the third fold is 8.5 mm: 6.5 mm.
[0044]
Further, the dimensions of the fourth bellows-like (8) to 12th bellows-like folds, and the height (hx) and the height (hy) of the lower folds of the folds are very common.
[0045]
That is, in the figure, (20) is the upper surface including the inner surface of the wide Adamski type UFO shape, and (21) is the lower surface including the inner surface of the wide Adamski type UFO shape. Has a 20 mmR bay shape (9) in this embodiment projecting outward, whereas the lower surface (21) has a straight line shape (11) through a 0.8 mmR protruding arc shape (10). Is an important point.
[0046]
The valley (18) having a small inner diameter receives a compressive pressure and generates a pressure stress. When the compression pressure is removed, the stress acts to release the stress and restores the stretched state. When the cap (14) is tightened under pressure and atmospheric pressure is applied, the container body (1) maintains the shortened state, and when the compressive stress is not generated due to the difference in the inner diameter of the valley (18), the vessel body (1) is maintained in the shortened state. It will be.
[0047]
In this embodiment, as described above, the diameter of the fold of the shoulder (C) of the container body (1) increases as the diameter of the fold decreases, and as a result, each crushed fold has an outer periphery with an inner periphery. Are superimposed on the upper slope.
[0048]
Then, when pressing the split ball (4) on the upper surface and / or the shoulder of the mouth part (3), the pressing force is the same as the pressing force (F1) on the outer periphery of each fold as shown in FIG. Result As shown in FIG. 11, the wall of the trunk (A) including the central part and the lower part is overlapped in an inclined shape in the opposite direction to the shoulder (C) whose outer periphery is lower than the inner periphery. Can be
[0049]
Thus, in the crushed container body (1), a split ball (4) and a bay shape (9) forming an inclined portion above the fold of the shoulder portion (C), and a body portion (A). This is why the slopes below the folds are so-called "balanced" so that the container body (1) can remain collapsed without having to recap the cap (14).
[0050]
As a result, in repeated experiments, the height (volume) of the container body (1) was reduced to 1/3 to 1/4 or less. Even if the container body (1) was discarded in a trash box or the like, the space was significantly reduced. It is.
[0051]
Further, as described above, in the embodiment of the present invention, by pressing the spout (3), the spout (3) is embedded in the container main body (1), and at the same time, the bottom of the container main body (1). (B) The periphery is also buried in the container body (1) by the same operation as the case where the shoulder (C) of the container body (1) is inverted, so that the empty container body (1) is discarded as it is. The volume (height) can be reduced to about 1/5 of that of the part.
[0052]
Further, since 500 ml of a product which is usually sold as a drinking container is almost never "drinked up" at once. Therefore, it is necessary to carry a container having an empty portion with the same volume even if there is a drink left behind. In this regard, the container of the present invention can be easily carried in a handbag because the portion that is emptied after drinking is shrunk so that it can be carried.
[0053]
In the case of a child or a woman with relatively weak power, the action of crushing the container body (1) not only depends on the "hand" but also can be extremely easily crushed by stepping on the foot as shown in FIG. .
[0054]
In plastic bottles used for many beverage containers, a flat publication portion (J) of a trademark, a description of the content or a display indicating the source is provided at an intermediate portion of the container body (1), which is shown in FIGS. The results are shown in FIG.
[0055]
The operation of squeezing the empty container body (1), which has swallowed up the contents in this container, is the same as described above, and a detailed description thereof will be omitted. In the middle part, the inner diameter is formed substantially equal to the outer diameter of the bellows-shaped part (2) of the container body (1). Therefore, when the container body (1) is crushed from above and below, the drinking part (3) is formed. ) As well as the bottom (B) and the periphery are pushed into the publishing part (J) and the squashed state is maintained without the appearance of good shape. And the abandoned state looks good.
[0056]
(Other embodiments)
In the above-described embodiment, the outer cross-sectional shape of the container body (1) is a cylinder or a shape similar thereto. However, if the shape in the longitudinal and longitudinal direction is a drum shape, it is easy to grasp, and if the shape is a truncated cone (K) or a truncated pyramid as shown in FIG. 20, stability is good. You can choose one.
[0057]
In addition, in the container body (1), the above-mentioned display portion (J) is provided only at the lower portion of the container body (1) as shown in FIG. 21, or only at the upper portion as shown in FIG. 22, or as shown in FIG. It may be provided.
[0058]
Furthermore, in the above-described embodiment, the bellows-like shape (2) formed in the container body (1) is an annular fold that is continuous in the vertical direction.
[0059]
However, when this is formed into a continuous spiral shape, when the container is crushed, a torsional force is applied in addition to a pressing force from above and below toward the upper or center of the container body (1), so that the container can be more easily crushed. found. The shape of the spiral is not limited to one, but may be several.
[0060]
【The invention's effect】
The main effect of the present invention described above is that when the container body is discarded, the volume can be made extremely small, and the number of containers that can be stored in a trash box or the like is greatly increased.
[0061]
In addition, since the reduced container body can achieve a large amount of transport at the same time, the collection cost and the labor cost for cleaning and collection can be significantly reduced.
[0062]
Further, the container body of the present invention has a good appearance of its appearance, and gives a great interest to a user, and the bellows shape of the container body serves as a friction stop, so that the container body may slide down during use. Also, the possibility of overflowing the contents can be prevented beforehand.
[0063]
Further, the shape of the container body crushed by the present invention is good in design and can be used as it is as an external container.
