Description

【0001】
【産業上の利用分野】
本発明は、粉体、顆粒、小片やそれらの混合物などの湿度を嫌う内容物、例えばふりかけ、調味料、洗剤、栄養剤などに使用するカップ状振出し紙容器に関するものである。
【0002】
【従来の技術】
従来、湿度を嫌う内容物の振出し容器としては、カップ状のガラス容器を用いたカップ状振出しガラス容器が一般に使用されていた。このカップ状振出しガラス容器(2)は、例えば、図2に示すように、カップ状ガラス容器(200)の側壁(210)上端の口部周縁突起(211)に、振出し口(42)と開封用凹部(43)とをもつ金属蓋(40)の周縁を巻き締め(41)して固設し、この金属蓋(40)の上面の振出し口(42)の全体と開封用凹部(43)の部分にわたって、下面に感熱接着剤が塗布されいる封止シート(50)を被せ、振出し口(42)の周辺を熱接着し、振出し口(42)を封止してカップ状ガラス容器(200)を密封し、一方、開封用凹部(43)上は未接着にして開封用つまみ(51)を設け、さらに、天板(62)に金属蓋(40)の振出し口(42)と圧接する封止突起(63)と、側壁(61)下方内側にカップ状ガラス容器(200)の口部と嵌合する嵌合突起(64)とを備えたプラスチック蓋(60)を冠着させたものであった。
【0003】
【発明が解決しようとする課題】
しかしながら、カップ状振出しガラス容器は、防湿性は非常に良好であるが、重いため流通過程で輸送費用や保管費用が高く、また、破損し易いなどの問題があった。さらに、最近では、環境保全の立場から、使用後の廃棄処理時に、構成部品を分別収集しようとしても、カップ状ガラス容器の口部に金属蓋が強固に巻き締めされているため、一般の消費者にとってはカップ状ガラス容器と金属蓋とを分離することが難しい問題もあった。
【0004】
本発明は、湿度を嫌う内容物の振出し容器として、従来のカップ状振出しガラス容器の上述した問題点を解決したものであり、防湿性がよく、軽く、破損しにくく、使用後の廃棄処理時に、構成部品の分別がし易く、また、積み重ね可能なカップ状振出し紙容器を提供するものである。
【0005】
【課題を解決するための手段】
第1の発明は、図1及び図3に示すように、側壁(110)の容器内側の積層材料(300)の貼合わせ端部(112)の断面と、底板(120)の積層材料(300)の端部の断面とが内容物に接しないように、最外層と最内層に熱融着性樹脂層(320,330)を形成する紙層を主体とする積層材料(300)を用いて作製されたカップ状紙容器(100)の口部に、上方にフランジ(11)を有する口部補強リング枠(10)を嵌入して、側壁(110)の上部内側と口部周縁巻込み部(111)の上面とに接着させて固着し、この口部補強リング枠(10)のフランジ(11)の上面に開封用つまみ(21)をもつ封止シート(20)を熱融着して、カップ状紙容器(100)の開口部(130)を密封し、さらに、天板(32)に振出し口(34)と、この振出し口(34)を開閉するヒンジ(38)を介して天板(32)に接続する子蓋(33)と、天板(32)の下面に口部補強リング枠(10)に嵌合するインナーリング(35)と、側壁(31)下方内側にカップ状紙容器の口部と嵌合する嵌合突起(37)とを備えたプラスチック蓋(30)を冠着したことを特徴とするカップ状振出し紙容器(1)である。
【0006】
第2の発明は、第1の発明に記載のプラスチック蓋(30)の天板(32)の上面に、カップ状振出し紙容器の底部を固定する積重ね用固定突起(36)を設けたことを特徴とするカップ状振出し紙容器(1)である。
【0007】
上述のカップ状紙容器を構成する積層材料は、最外層と最内層に、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレートなどの熱融着性樹脂層を形成し、中間層に、紙層を主体としてプラスチック層、金属箔層、金属蒸着薄膜層などを積層した積層基材層を形成したものである。なお、積層材料の構成は、使用目的に合わせて選択するものである。
【0008】
また、口部補強リング枠の材質は、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレートなどが用いられるが、カップ状紙容器の口部への固着は、熱融着又は接着剤を用いて接着する。
【0009】
また、封止シートは、防湿性の積層シートで、下面に熱融着樹脂層が設けられたものである。また、口部補強リング枠への熱融着は、容器使用時に、封止シートを口部補強リング枠から剥離可能に設けるものである。
【0010】
そして、プラスチック蓋は、子蓋をヒンジを介して接続するため、材質としてはポリプロピレンの使用が好ましい。なお、図1に示すように、振出し口(34)を開閉する子蓋(33)には、封止シートを剥離後の容器の密封性を向上させるため、下面に振出し口(34)と嵌合するインナーリング(39)を設けることが好ましい。
【0011】
【作用】
本発明のカップ状振出し紙容器のカップ状紙容器は、紙層を主体としてプラスチック層、金属箔層、金属蒸着薄膜層などを積層した積層材料より作られているため、従来のカップ状振出しガラス容器に比較して、同一容量の場合には、容器重量を1/2〜1/3程度に軽量化でき、しかも外部の衝撃により破損しにくい。
【0012】
また、本発明のカップ状振出し紙容器は、カップ状紙容器、口部補強リング枠、封止シート、そしてプラスチック蓋より構成されているが、それぞれの接続は、接着か嵌着であるため、金属蓋が強固に巻き締めされている従来のカップ状振出しガラス容器に比較して、使用後の廃棄処理時に、構成部品の分離が容易であり、分別収集がし易い。さらに、カップ状紙容器は、軽くて押し潰せるため、廃棄物の嵩を少ない。
【0013】
また、本発明のカップ状振出し紙容器のカップ状紙容器の周壁は、最外層と最内層とにプラスチック層を有し、中間層にプラスチック層、金属箔層などが積層された積層材料で作られているため、防湿性がよく、また、容器内の積層材料の端部の断面が、内容物に接触しないようにプラスチック層で覆われているため、内容物の保護性が良好となる。
【0014】
そして、第2の本発明のカップ状振出し紙容器のプラスチック蓋の上面には、カップ状振出し紙容器の底部を固定する積重ね用突起が設けられているため、カップ状振出し紙容器の積み重ねが可能となる。
【0015】
【実施例】
まず、ラミネート加工法によって、〔容器外側〕ポリエチレン層(20μm)/印刷層/紙層(300 g/m2 )/接着剤層/アルミニウム箔層(9μm)/ポリエチレンテレフタレート層(12μm)/接着剤層/ポリエチレン層(60μm)〔容器外側〕構成の紙容器用積層材料を作製した。これとは別途に、〔上側〕ポリエチレンテレフタレート層(12μm)/接着剤層/アルミニウム箔(9μm)/接着剤層/ポリエチレン(20μm)/ポリエチレン系接着性樹脂(40μm)〔下側〕構成の封止シート用積層材料を作製し、この封止シート用積層材料から、開封用つまみ(21)をもつ図1に示す封封シート(20)を打抜き加工した。次に、射出成形法によって、上方にフランジ(11)を有する図1に示す口部補強リング枠(10)を、低密度ポリエチレンを用いて作製した。また、これとは別途に、射出成形法によって、天板(32)に振出し口(34)と、この振出し口(34)を開閉するヒンジ(38)を介して天板(32)に接続する子蓋(33)と、カップ状振出し紙容器の底部を固定する積重ね用固定突起(36)と、天板(32)の下面に口部補強リング枠(10)に嵌合するインナーリング(35)と、側壁(31)下方内側にカップ状紙容器の口部と嵌合する嵌合突起(37)とを備えた図1に示すプラスチック蓋(30)を、ポリプロピレンを用いて作製した。なお、振出し口(34)を開閉する子蓋(33)には、封止シートを剥離後の容器の密封性を完全にさせるため、下面に振出し口(34)と嵌合するインナーリング(39)を設けた。
【0016】
次に、前述した紙容器用積層材料を用い、PMC(Pachaginng Machinery Corp.)社製カップ成形機で、側壁(110)の容器内側の積層材料の貼合わせ端部(112)の断面と、底板(120)の積層材料の端部の断面とが、内容物に接しないように作製した図1に示す側壁(110)の上端外縁に口部周縁巻込み部(111)をもつカップ状紙容器(100)を作製した。なお、側壁(110)の容器内側の積層材料の貼合わせ端部(112)は、図3に示すように、スカイブ・ヘミング加工によって、スカイブ面(114)を折り返して接着して、積層材料(300)の最内層のポリエチレン層で覆った。次に、上述のカップ状紙容器(100)に、内容物として‘ふりかけ,を充填しのち、カップ状紙容器(100)の口部に、前述した口部補強リング枠(10)を嵌入して、側壁(110)の上部内側と口部周縁巻込み部(111)の上面とに超音波シール法で熱融着して固着し、そして、この口部補強リング枠(10)のフランジ(11)の上面に前述した封止シート(20)を熱融着して、カップ状紙容器(100)の開口部(130)を密封し、さらに、子蓋(33)で振出し口(34)を閉じた状態の前述したプラスチック蓋(30)を冠着して、本実施例のカップ状振出し紙容器(1)を作製した。なお、本実施例のカップ状振出し紙容器と比較するため、内容物として‘ふりかけ,を充填した同一容量の図2に示す従来のカップ状振出しガラス容器(2)を作製した。次に、これらの本実施例のカップ状振出し紙容器と比較例のカップ状振出しガラス容器とを、室内保管して内容物の吸湿状態を調べるため、風袋ともの重量変化を測定し、その結果を表1に示す。
