Description

【０００１】
【発明の属する技術分野】
この発明は、トイレットやキッチンとか、スーパーマーケットなどに備えたロール紙または、これに近似したロール巻フィルム類をカットして使用する際に用いて好適なロール紙繰り出し容器における紙切り蓋板の改良に関する。
【０００２】
【従来の技術】
ロール紙または、これに近似したロール巻フィルム類を保持するロール紙ホルダの紙切り蓋板としては、従来、特許第２７２２９０２号公報、特開平７−２４６５８８号公報および特開２００１−３００８８６号公報などにそれぞれ記載のように、薄肉の金属板や硬質プラスチック板の前辺に先端が鋭く尖った連続三角波形硬質刃先を有する刄板とか、特開２００２−５１９３５号公報に記載のように、ロール紙ケース内からシーソ式に出入りする薄肉の金属板や硬質プラスチック製の連続波形状の硬質刃先を有する紙切り蓋板がそれぞれ周知である。
【０００３】
【発明が解決しようとする課題】
これら各従来例のうち、前者三つの従来例は、いずれも薄肉の金属板や硬質プラスチック板の前辺に先端が鋭く尖った連続三角形状の硬質刃先を有する紙切り蓋板であるから、ロール紙やロール巻フィルムとかシート類を上記紙切り蓋板でカットするときのように、手指を上記紙切り蓋板の鋭く尖った連続三角形状の硬い刃先に近づけた際、手指が僅かでも上記の硬く尖った刃先に触れると指先を直ちに傷付けてしまう危険が有るという本質的かつ、大きな問題点が有る。
【０００４】
また、後者の特開２００２−５１９３５号公報のものでは、紙切り蓋板をロール紙繰り出し容器のスリットからシーソ式に出入りさせるものであるから、構造複雑・組み立て面倒でしかもコスト高で故障も多いという本質的な問題点が有るほかに、この従来例の刃先は硬く連続波形状であるが、いくら連続波形状であるからといっても、刃先は薄肉で鋭く硬いため、依然としてこの刃先に手指が触れると指先を負傷する危険が有るという本質的かつ、大きな問題点が有る。
さらに、従来一般的な紙切り蓋板の前辺に対する帯状刄板の実装手段としては、紙切り蓋板内面に配置した刄板を当て板でサンドイッチ式に挟み込み、この当て板余白部分を紙切り蓋板内面に超音波溶着する刄板実装手段や、紙切り蓋板内面に配置した刄板の孔から突出した紙切り蓋板内面突起の押し潰し実装とか、ねじ止め実装などの作業性が悪い刄板実装手段が従来周知であるが、これではその組立製造・部品管理・保守点検などのすべての面で扱い辛く不便で面倒であるという本質的かつ、大きな問題点も有る。
【０００５】
この発明は、ロール紙繰り出し容器における紙切り蓋板に刄板を実装し易くすると共に、刄板刃先を櫛歯状弾性刃先とすることで、手指に優しく安全かつ、確実にロール紙やロール巻フィルムをカット可能にすることを目的とする。
【０００６】
上記した本発明の目的は、上部開放の容器内に収納したロール紙の上から容器開口縁に後部枢支の紙切り蓋板を被せ、その前辺下面と容器前辺とでロール紙繰り出し部分を弾圧し、この繰り出し部分を外力により紙切り蓋板の前辺刃先で切断可能となしたロール紙繰り出し容器において、前記紙切り板の前辺に側端開放の前端開溝と、この開溝に連通した後部膨大溝とを削設し、上記前端開溝の上面と上記後部膨大溝の上面は連続した平面で、前記後部膨大溝は前記平面と対向する面が窪んだ形状となっており、前記前端開溝と前記後部膨大溝の開放側端から先端が櫛歯状の弾性刄先を有した帯状刄板を、前記帯状刄板の後部に設けられた膨出後辺が前記後部膨大溝と嵌合するように挿入埋設し、前記後部膨大溝に設けられた凹部へ前記膨出後辺に突設された抜け止め突起を圧入することで、前記櫛歯状弾性刃先が前記前端開溝から突出した状態でその抜け止めを施こしたことで達成できた。
【０００７】
【発明の実施の形態】
本発明の実施の形態例について図面を参照して説明する。
この発明の基本的な実施形態の一例としては、図１のようにトイレの壁面などに定着設置して使用する金属やプラスチックなどで側面ほぼ円形に作った上部開放の容器１内に、芯管２Ｃに巻装したロール紙２または芯管無しのロール紙２を図２のように例えば投げ込み式に収納し、その繰り出し部分２Ａ（摘まみ代２Ｂ）を図２のように手前に繰り出し定位すると共に、その上から容器開口縁１Ｂに金属やプラスチックなどで側面ほぼ弧形に作った紙切り蓋板３をその自己重力で後部左右に設けた周知の枢支部３０を支点として図２および図３のように被せ、上記自己重力により蓋板前辺下面３Ａと容器前辺１Ａとでロール紙繰り出し部分２Ａを弾圧し、この繰り出し部分２Ａを紙切り蓋板前辺刃先で図２のように切断可能となしたロール紙繰り出し容器をを構成するに当たり、本発明では先ず、図１のように前記紙切り蓋板３の前辺３Ｂに側端開放の前端開溝３Ｃと、この開溝３Ｃに連通した後部膨大溝３Ｄとを削設する。
【０００８】
次いで、ポリエステル・エラストマや硬質合成ゴムなどの手指に優しく柔軟で表面摩擦が大きい可撓弾性素材で成形した図１のような帯状刄板４に膨出後辺４Ａとこれに連接した櫛歯状弾性刃先４Ｂとを一体的に射出成形し、帯状刄板４の膨出後辺４Ａを蓋板前辺３Ｂの後部膨大溝３Ｄ内にその開放側端から図１の矢示方向に平行移動させ、上記櫛歯状弾性刃先４Ｂを前記紙切り蓋板前辺３Ｂの前端開溝３Ｃから突出させつつ、図２・図４のようにうに満遍なく挿入埋設した後、紙切り蓋板前辺３Ｂに対し帯状刄板４の抜け止めを施こすことで、上記各図のような本発明によるロール紙繰り出し容器における紙切り蓋板を構成できた。
ただし、前記帯状刄板４の抜け止め手段としては、前記後部膨大溝３Ｄの内面に対して帯状刄板４を圧入したり、接着することで抜け止めを施こしてもよく、また図５のように前記帯状刄板４の側端付近に突設した抜け止め突起４Ｄや膨出側端４Ｅなどの抜け止め突部４Ｃをその弾力に抗し後部膨大溝３Ｄに図４のように圧入しても紙切り蓋板前辺３Ｂに対する帯状刄板４の抜け止めを施こせる。
【０００９】
本発明の基本構成は以上のようなもので、以下その動作例につき説明する。
先ず、ロール紙繰り出し容器１内にロール紙２を図２・図３のように回転可能に収納した後、ロール紙２を予じめ手前に所望長さだけ引き出して最初の繰り出し部２Ａを作っておき、その後紙切り蓋板３を上記各図のように閉じると、ロール紙２の上部前寄り外周面に前記紙切り蓋板３の前辺下面３Ａが自己重力で図３のように圧接してロール紙２の使用状態となり、上記繰り出し部２Ａを図２の鎖線のように櫛歯状弾性刃先４Ｂに沿わせて上向き斜めに引っ張り上げることで、前記紙切り蓋板３を自己重力で圧接固定したまま、この繰り出し部２Ａをそのカット部分Ｑで前記櫛歯状弾性刃先４Ｂにより次々にカットして使用できる。
【００１０】
なお、上記ロール紙繰り出し部２Ａをカットするに要する時間は、一秒程度の極く短時間であるが、このロール紙カット時などに前記櫛歯状弾性刃先４Ｂに手指が触れたとしても、これら多数の刃先４Ｂは、前記のように手指に優しいポリエステル・エラストマなどの柔軟で表面摩擦が大きい可撓弾性プラスチックで射出成形した弾性刃先４Ｂであるから、手指を少しも傷つけることなくロール紙に対する良好な切れ味を保つことができ、上記カット部分Ｑを前記櫛歯状弾性刃先４Ｂで次々と確実軽快にカットし終えることができた。
【００１１】
此処で、前記櫛歯状弾性刃先４Ｂにより、ロール紙繰り出し部２Ａをそのカット部分Ｑで前記のように軽快にカットできる理由を以下詳細に吟味する。
前記櫛歯状弾性刃先４Ｂによる上記ロール紙２のカット時に、多数の各弾性刃先４Ｂには、それぞれ上記ロール紙カット部分Ｑによる上向き斜めのロール紙２の引っ張り力が次々に加わり、この引っ張り力により表面摩擦が大きい多数の各弾性刃先４Ｂは、上記カット部分Ｑに対して滑ることなく次々にその可撓弾力に抗し、上向き斜めに僅少寸法だけ次々に撓み動きながら前記カット部分Ｑをカットし始めた直後、各弾性刃先４Ｂから上記カット部分Ｑの切断途中部分が次々に通過しようとする瞬間に、これら多数の各弾性刃先４Ｂは、その可撓弾性復帰力で次々に原状復帰しようとするため、これら各弾性刃先４Ｂの復帰瞬発力が上記と同様に滑ることなくダイレクトに前記引っ張り力と共に上記ロール紙切断途中部分に次々と強く加わり、ロール紙をカットできるものと推測でき、刃先４Ｂが手指に優しい櫛歯状弾性刃先であっても、ロール紙２に対する切れ味を損なうことなく、しかも手指に傷つけることなくロール紙やロール巻フィルムのカット部分Ｑを次々と確実軽快にカットできた。
【００１２】
このようにして、ロール紙２を使い終えたときに新しいロール紙を容器１内に収納セットするには、前記紙切り蓋板３をその枢支部３０を支点とし、上向き回動させてロール紙繰り出し容器をオープン状態とし、使用済のロール紙芯管２Ｃを容器内から取り出した後、新しい芯管付きロール紙２または芯管無しのロール紙２を前記のように容器１内に収納セットすることができ、その後紙切り蓋板３をロール紙２の上部に前述したように被せることで、図３のような次回の使用形態を採ることができる。
【００１３】
次に、軽い紙切り蓋板３を用いても、その自己重力に関係なく前記蓋板前辺下面３Ａと容器前辺１Ａとでロール紙繰り出し部分２Ａをより一層安定に弾圧できる本発明の第二の実施形態例を以下詳細に説明する。
この第二の実施形態例では、先ず前記各図に示す容器１の後面板１Ｃに前記紙切り蓋板枢支部３０を経た紙切り蓋板後縁３１に上記各図のように係合してこれを手前斜め上向きに弾撥する前下がり斜面６Ａ付きの閉蓋弾圧弾片６を一体成形した強弾性プラスチック製などの弾片突設部材７を図６のように用意する。
【００１４】
そして、前記弾片突設部材７に突設した係止鉤片７Ａを図６矢示のように容器後面板１Ｃの係止孔縁１Ｄに鉤片固有弾力に抗して係入後、この係止孔縁１Ｄに前記係止鉤片７Ａをその弾力により、パチンと復帰させて係合させることで、容器後面板１Ｃに前記弾片突設部材７を図１・図７のように定着することで、前記閉蓋弾圧弾片６を前記各図のように容器１の後面板１Ｃに前向きに突設する。
したがって、上記弾片６の前下がり斜面６Ａまたは手前斜め上に弾撥するようにした弾片６自体による前記蓋板後縁３１に対する上向き弾撥力で、テコ作用により蓋板前辺下面３Ａ（または縦リブ３Ｅ）を繰り出し途中のロール紙２が千切れない程度に容器前辺１Ａに弾圧でき、蓋板前辺３Ｂに上向きに加わるロール紙切断力では紙切り蓋板３が軽くても、この蓋板３の浮上を阻止してロール紙やロール巻フィルムのカット部分Ｑを次々と確実にカットできると共に、切断後の容器内ロール紙反転による容器外ロール紙繰り出し部分２Ａ（摘まみ代２Ｂ）の容器内引き込みを阻止でき、快適に使用できるようになった。
【００１５】
前記弾圧閉蓋状態にある紙切り蓋板３をダメ押し的に閉蓋維持するために、本発明の第三の実施形態例では、図３のように紙切り蓋板３の前側端に下向きの突片５を突設し、前記突片５の外面に図８のように形成した斜面付き突起（または単なる突起や凹所とか孔）などの閉蓋ロック部５Ａを前記容器１の前側端内面に同図８のように形成した斜面付き突起（または凹所や孔とか単なる突起）などの閉蓋ロック部５Ｂに紙切り蓋板閉蓋時に同図８矢示の順序で各閉蓋ロック部５Ａ・５Ｂ同士を前記突片５の弾力に抗してパチンと係合させることで、上記弾圧閉蓋状態をダメ押し的に維持できるようにすることもでき、閉じた紙切り蓋板３にロール紙切断による上向きのロール紙切断力が加わっても、前記紙切り蓋板３を押さえずにその前辺刃先でロール紙繰り出し部分２Ａを上記図２のように片手で無造作に切断できる本発明第三の実施形態例による閉蓋ロック付きロール紙繰り出し容器も構成できる。
【００１６】
ただし、各閉蓋ロック部５Ａ・５Ｂ同士の弾接係合ポイントは、使用ロール紙２の紙質や厚みの多様性を考慮し、前記弾圧閉蓋状態にある紙切り蓋板３が前記閉蓋弾圧弾片６の弾撥力に抗して上向きに約１ｍｍ程度持ち上がるように若干のアロワンスを持たせて各閉蓋ロック部５Ａ・５Ｂの突設箇所を位置決めする。
また、上記各閉蓋ロック部５Ａ・５Ｂ同士の係合強度は、前記弾圧閉蓋状態を維持して二枚合わせのロール紙２や厚手のロール紙２を紙切り蓋板３の前辺刃先で切断する時のように、閉蓋状態にある紙切り蓋板３にやや強い上向きのロール紙切断力が加わっても、紙切り蓋板３が図２のように妄りに浮上せず、かつ、紙切り蓋板３を所望時に手指などでは開蓋できる程度の強度に設定する。
【００１７】
【実施例】
前記櫛歯状弾性刃先４Ｂの紙切り蓋板前辺３Ｂに対する出面寸法は、２〜７ｍｍ程度とし、この範囲内で多数の各弾性刃先４Ｂを互いに同寸、または所定本数毎に異寸の出面寸法とし、また各弾性刃先４Ｂの太さは、０．５〜３ｍｍ程度とし、各刃先４Ｂの突設ピッチは、０．５〜２ｍｍ程度が好ましい。
また、前記紙切り蓋板３の前辺３Ｂを弯曲形成し、この弯曲前辺３Ｂに形成した後部膨大溝３Ｄ内に、この溝に対応した形状の帯状弯曲刄板４の膨出後辺４Ａを挿入し、その櫛歯状弾性刃先４Ｂを前記弯曲した前辺３Ｂから満遍なく露出配置して抜け止めを施こした紙切り蓋板３を用いてもよい。
【００１８】
さらに、前記櫛歯状弾性刃先４Ｂを上下に齟齬させて突設することで、これら各刃先の前記撓み復帰瞬発力を僅少寸法だけ上下に振り分けてロール紙切断途中部分に次々と加えることができ、手指には優しく、ロール紙に対しては、より一層鋭い切れ味を得ることができた。
本発明第二の実施形態例における閉蓋弾圧弾片６の突設手段は、前記の突設手段以外に例えば上記突片６をゼンマイ鋼などの強弾性材で作り、これを容器後面板１Ｃの内面にねじ止めとかインサート成形などの固定手段で突設してもよく、また、上記突片６を例えばプラスチック容器１の成形時に容器後面板１Ｃに一体的に成形したり、閉蓋弾圧弾片６を強弾性プラスチック材により容器１の成形時に同一金型内で所謂二色一体成形して突設してもよく、さらに上記突片６を一体突設した弾片突設部材７は、容器後面板１Ｃにねじ止めや接着などで定着することで、上記突片６を容器後面板１Ｃに突設してもよい。また、紙切り蓋板３の前部における例えば両側に突設した突片５でロール紙２の両側を繰り出し案内することもできる。
【００１９】
なお、前述した開蓋状態にある紙切り蓋板３が妄りに倒れないようにするには、紙切り蓋板３の開蓋状態を保持するための凹凸係合による開蓋保持部を前記容器１および紙切り蓋板３の各対向部分に具備することで可能となった。
また、前記容器１と紙切り蓋板３との側面形状をそれぞれほぼ円形およびほぼ弧形とすることで、より一層小型軽量かつ、スマートなロール紙繰り出し容器となるし、さらに前記紙切り蓋板３の前辺下面３Ａに前記ロール紙２の周方向に沿わせて複数の縦リブ３Ｅを並列突設することで、ロール紙２の繰り出し部分２Ａの弾圧部分がスポット的に分散するため、ロール紙２の繰り出し案内のスムース化と、その千切れ防止とがそれぞれ一層確実になった。
【００２０】
本発明における請求項１の発明によれば、前記紙切り蓋板３の前辺３Ｂに側端開放の前端開溝３Ｃと、この開溝３Ｃに連通した後部膨大溝３Ｄとを削設し、この膨大溝３Ｄ内にその開放側端から前記各溝に対応した形状の帯状刄板４の膨出後辺４Ａを挿入し、前記刄板４の櫛歯状弾性刃先４Ｂを前記蓋板前辺３Ｂから満遍なく突出定位した状態で、蓋板前辺３Ｂに対する帯状刄板４の抜け止めを施こすだけで紙切り蓋板前辺３Ｂに帯状刄板４を実装できたので、蓋板前辺３Ｂに対する帯状刄板４の抜け止め実装作業を大幅に簡素化でき、前述したような従来一般的な面倒で作業性が悪い刄板実装作業が、本発明では一切不要となり、その組立製造・部品管理・保守点検などのすべての面で、より一層扱い易く、価格の低減も実現できたという優れた効果が有る。
【００２１】
また、前記請求項１の発明によれば、前記刃先４Ｂがそれぞれ手指に優しい櫛歯状弾性刃先であっても、ロール紙２やロール巻フィルムとかシート状物に対する切れ味を前述したように損なうことなく、前記カット部分Ｑを連続して確実軽快にカットできるし、上記弾性刃先４Ｂに手指が触れたとしても、この刃先は手指に優しい弾性刃先４Ｂであるから、指先を傷付けることなく安全かつ、確実軽快にロール紙やロール巻フィルムとかシート類をその所望部分からカットできたという優れた効果も有る。
【００２２】
また、請求項２の発明のように櫛歯状弾性刃先４Ｂ全体の櫛歯輪郭形状を例えば弯凸櫛歯状や弯凹櫛歯状など種々の刃先輪郭形状にすれば、ロール紙２やロール巻フィルムとかシート類の厚さや、その種類・大きさに応じた刃先輪郭形状の櫛歯状弾性刃先４Ｂを採用でき、その切れ味を木目細かく選定できた。
【００２３】
また、本発明の請求項３のように、前記紙切り蓋板３をその自己重力で前記ロール紙２の上部前寄り外周面に弾圧可能に配設すれば、蓋板弾圧用のばね部材が不要となり、この分だけロール紙繰り出し容器を安価に多量製造でき、また、本発明における請求項６の発明によれば、前記容器１の後面板１Ｃに前記蓋板後縁３１に係合する閉蓋弾圧弾片６を突設し、前記蓋板後縁３１に対する弾片６の上向き弾撥力により、軽い紙切り蓋板３を用いても、その枢支部３０を経た蓋板前辺下面３Ａをテコ作用で容器前辺１Ａにロール紙２を挟み弾圧定位したまま、その繰り出し部２Ａを前記櫛歯状弾性刃先４Ｂにより次々にカットして使用できると共に、容器内ロール紙の反転によるロール紙繰り出し部分２Ａの容器内引き込みを阻止でき、しかもロール紙繰り出し容器全体としての重量を軽減でき、その組立製造・部品管理・販売・使用・保守点検などのすべての面で扱い易く、価格的にも有利になったという効果を付加できた。
【００２４】
さらに、本発明における請求項５の発明のように、前記閉蓋弾圧弾片６を一体的に突設した弾性プラスチック製の弾片突設部材７をその係止鉤片７Ａで容器後面板１Ｃの係止孔縁１Ｄに係合させて係止定着すれば、容器後面板１Ｃに対する閉蓋弾圧弾片６の取り付け作業性を一段と高め得るし、前記請求項６の発明のように前記紙切り蓋板３の前側端に突設した突片５の閉蓋ロック部５Ａをこれに対向する容器１の閉蓋ロック部５Ｂに前記突片５の弾力に抗し係合させ、前記紙切り蓋板前辺刃先に加わる上向きのロール紙切断力による閉蓋紙切り蓋板３の浮上をダメ押し的に阻止できるようにすれば、紙切り蓋板３を妄りに浮上させずにロール紙２を無造作に切断でき、さらに前記請求項７の発明のように、前記紙切り蓋板３の開蓋状態を確保するための開蓋保持部を前記容器１および紙切り蓋板３の各対向部分に具備すれば、開蓋状態にある紙切り蓋板３は妄りに倒れず、より一層安全となる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a paper cutting cover plate in a roll paper feeding container suitable for use when cutting and using roll paper provided in a toilet or kitchen, a supermarket or the like, or roll films similar to the roll paper. .
[0002]
[Prior art]
Conventionally, as a paper cutting cover plate of a roll paper or a roll paper holder for holding a roll film similar to the roll paper, Japanese Patent No. 2722902, Japanese Patent Application Laid-Open No. 7-246588, Japanese Patent Application Laid-Open No. 2001-300886, etc. As described in JP-A-2002-51935, or a roll paper having a continuous triangular corrugated hard cutting edge with a sharp tip at the front side of a thin metal plate or hard plastic plate A thin metal plate that enters and exits from the case in a seesaw manner and a paper cutting lid plate that has a continuous blade-shaped hard cutting edge made of hard plastic are well known.
[0003]
[Problems to be solved by the invention]
Among these conventional examples, the former three conventional examples are paper cutting cover plates each having a continuous triangular hard edge with a sharp tip at the front side of a thin metal plate or hard plastic plate. When a finger is brought close to the sharp, sharp, continuous triangle-shaped cutting edge of the paper-cutting cover plate as in the case of cutting paper or roll film or sheets with the paper-cutting cover plate, even if the finger is slightly above the There is an essential and big problem that there is a risk of hurting the fingertip immediately when touching a hard and sharp blade edge.
[0004]
Further, in the latter Japanese Patent Application Laid-Open No. 2002-51935, the paper cutting cover plate is moved in and out in a seesaw manner from the slit of the roll paper feeding container, so that the structure is complicated, the assembly is troublesome, the cost is high, and there are many failures. The cutting edge of this conventional example is hard and has a continuous wave shape. However, no matter how a continuous wave shape is, the cutting edge is still thin and sharp, so it still has a finger on the cutting edge. There is an essential and big problem that there is a risk of injury to the fingertip when touched.
Furthermore, as a means for mounting a belt-like board on the front side of a conventional paper-cutting cover plate, a board placed on the inner surface of the paper-cutting cover plate is sandwiched with a contact plate, and the margin portion of the contact plate is cut into paper. Poor workability such as the board mounting means that ultrasonically welds to the inner surface of the cover plate, the crushing mounting of the protrusion on the inner surface of the paper cutting cover plate that protrudes from the hole in the cover plate that is placed on the inner surface of the paper cutting cover plate, and screw mounting Conventionally, the board mounting means is well known, but this has an essential and big problem that it is difficult, inconvenient and troublesome in all aspects such as assembly manufacturing, parts management, maintenance and inspection.
[0005]
The present invention makes it easy to mount the paper plate on the paper cutting cover plate in the roll paper feeding container, and uses the paper plate blade edge as a comb-like elastic blade edge. The purpose is to make the film cuttable.
[0006]
The object of the present invention described above is to cover the roll opening portion of the roll paper housed in the upper open container with the paper pivoting cover plate of the rear pivot from the container opening edge, and the roll paper feeding portion between the lower surface of the front side and the front side of the container In the roll paper feeding container in which the feeding portion can be cut by the front edge of the paper cutting cover plate by an external force, a front end opening groove on the front side of the paper cutting plate and a side opening opening groove are provided. A rear enormous groove communicated with the upper end of the front end open groove and the upper surface of the rear enormous groove are a continuous plane, and the rear enormous groove has a shape in which the surface facing the plane is recessed. A belt-like saddle plate having a comb-like elastic tip from the open side end of the front end open groove and the rear enlarged groove, and a bulging rear side provided at the rear part of the belt-like saddle plate is the rear enlarged portion. Inserted and buried so as to fit into the groove, the bulge into the recess provided in the rear enormous groove By press-fitting the retaining projection projecting from the sides, could be achieved by the comb-like elastic blade is strained facilities its retaining in a state of protruding from the front end open grooves.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
As an example of a basic embodiment of the present invention, as shown in FIG. 1, a core tube is placed in an open top container 1 made of metal or plastic that is fixedly installed on a wall surface of a toilet, etc. The roll paper 2 wound around 2C or the roll paper 2 without the core tube is housed in, for example, a throw-in manner as shown in FIG. 2, and the feeding portion 2A (the gripping allowance 2B) is fed forward and localized as shown in FIG. 2 and 3 with a well-known pivotal support 30 provided on the left and right sides of the rear portion of the paper cutting cover plate 3 made of metal or plastic on the container opening edge 1B as a fulcrum by its own gravity. 2), the roll paper feeding portion 2A is elastically pressed by the self-gravity with the lower surface 3A of the front side of the lid plate and the front side 1A of the container, and this feeding portion 2A is cut with the front edge of the paper cutting lid plate as shown in FIG. Roll paper made possible In constructing the discharge container, in the present invention, first, as shown in FIG. 1, the front edge 3B of the paper cutting cover plate 3 is opened on the front side 3B, the front end groove 3C is opened to the side, and the rear enormous groove communicated with the groove 3C. Cut 3D.
[0008]
Next, a ridge ridge 4A and a comb-teeth shape connected to this are formed on a belt-like plate 4 as shown in FIG. 1, which is formed of a flexible elastic material that is soft to fingers and has a large surface friction, such as polyester elastomer and hard synthetic rubber. The elastic cutting edge 4B is integrally injection-molded, and the bulging rear side 4A of the belt-like rib plate 4 is translated in the rear enormous groove 3D of the lid plate front side 3B from the open side end in the direction indicated by the arrow in FIG. The comb-like elastic cutting edge 4B is inserted and embedded uniformly as shown in FIGS. 2 and 4 while projecting from the front end open groove 3C of the paper cutting cover plate front side 3B, and is then embedded in the paper cutting cover plate front side 3B. On the other hand, by preventing the belt-like gutter 4 from coming off, the paper cutting cover plate in the roll paper feeding container according to the present invention as shown in the above figures could be configured.
However, as a means for preventing the strip-shaped saddle plate 4 from coming off, the strip-shaped saddle plate 4 may be pressed into the inner surface of the rear enormous groove 3D or adhered thereto to prevent the strip-shaped saddle plate 4 from coming off. As shown in FIG. 4, the retaining projections 4C such as the retaining projections 4D and the bulging side ends 4E projecting in the vicinity of the side edges of the belt-like plate 4 are pressed into the rear enormous groove 3D against the elasticity. Even in this case, it is possible to prevent the belt-like plate 4 from coming off from the front side 3B of the paper cutting cover plate.
[0009]
The basic configuration of the present invention is as described above, and an example of its operation will be described below.
First, after the roll paper 2 is rotatably stored in the roll paper feed container 1 as shown in FIGS. 2 and 3, the roll paper 2 is drawn out by a desired length in advance and the first feed portion 2A is formed. Then, when the paper cutting cover plate 3 is closed as shown in the above drawings, the lower surface 3A of the front side of the paper cutting cover plate 3 is pressed against the outer peripheral surface of the upper side of the roll paper 2 by self-gravity as shown in FIG. Then, the roll paper 2 is used, and the paper cutting cover plate 3 is moved by self-gravity by pulling the feeding portion 2A obliquely upward along the comb-like elastic blade edge 4B as shown by a chain line in FIG. The feeding portion 2A can be cut and used one after another by the comb-like elastic cutting edge 4B at the cut portion Q with the pressure contact fixed.
[0010]
The time required to cut the roll paper feed portion 2A is a very short time of about one second, but even if a finger touches the comb-like elastic blade edge 4B when the roll paper is cut, These many cutting edges 4B are elastic cutting edges 4B which are injection-molded with a flexible elastic plastic which is soft and has a large surface friction, such as polyester elastomer which is gentle to fingers as described above. A good sharpness could be maintained, and the cut portion Q could be reliably and lightly cut one after another with the comb-like elastic cutting edge 4B.
[0011]
Here, the reason why the roll paper feeding portion 2A can be easily cut as described above by the cut portion Q by the comb-like elastic cutting edge 4B will be examined in detail below.
When the roll paper 2 is cut by the comb-like elastic blade edge 4B, a tensile force of the upward inclined roll paper 2 by the roll paper cut portion Q is applied to each of the elastic blade edges 4B one after another. Each of the elastic cutting edges 4B having a large surface friction is resistant to its elastic elasticity one after another without sliding against the cut part Q, and cuts the cut part Q while bending and moving one after another by a slight dimension. Immediately after starting to perform, at the moment when the cutting part Q of the cut part Q is going to pass one after another from each elastic cutting edge 4B, each of these many elastic cutting edges 4B tries to return to its original state one after another by its flexible elastic return force. Therefore, the return instantaneous force of each of the elastic cutting edges 4B is directly applied to the part in the middle of cutting the roll paper directly together with the pulling force without slipping similarly to the above. It can be assumed that the roll paper can be cut, and even if the cutting edge 4B is a comb-like elastic cutting edge that is kind to fingers, the sharpness of the roll paper 2 is not impaired and the roll paper or roll film is not damaged. The cut portion Q could be cut lightly and reliably one after another.
[0012]
In this way, in order to store and set a new roll paper in the container 1 when the use of the roll paper 2 is finished, the paper cutting cover plate 3 is pivoted upward with the pivot portion 30 as a fulcrum, and the roll paper is moved. After the feeding container is opened and the used roll paper core tube 2C is taken out from the container, a new roll paper 2 with a core tube or a roll paper 2 without a core tube is stored and set in the container 1 as described above. Then, by covering the paper cutting cover plate 3 on the top of the roll paper 2 as described above, the next usage pattern as shown in FIG. 3 can be adopted.
[0013]
Next, even if a light paper-cutting cover plate 3 is used, the roll paper feed portion 2A can be more stably repressed by the cover plate front side lower surface 3A and the container front side 1A regardless of the self-gravity. The second embodiment will be described in detail below.
In the second embodiment, first, as shown in the above drawings, the rear plate 1C of the container 1 shown in each of the drawings is engaged with the paper cutting cover plate trailing edge 31 through the paper cutting cover plate pivotal support portion 30 as shown in the above drawings. A bullet projecting member 7 made of a strong elastic plastic or the like integrally formed with a closed lid bullet member 6A having a front-falling slope 6A that repels this upward and obliquely upward is prepared as shown in FIG.
[0014]
Then, after engaging the locking rod piece 7A protruding from the protruding piece projecting member 7 into the locking hole edge 1D of the container rear plate 1C as shown by the arrow in FIG. By fixing the locking collar piece 7A to the locking hole edge 1D with its elasticity, it snaps into engagement with the locking hole edge 1D so that the protruding member 7 is fixed to the container rear plate 1C as shown in FIGS. As a result, the closed-end elastic bullet 6 protrudes forward from the rear plate 1C of the container 1 as shown in the respective drawings.
Therefore, the bottom plate front side lower surface 3A (due to the lever action) by the upward repelling force with respect to the rear edge 31 of the lid plate by the bullet piece 6 itself which is repelled to the front lower slope 6A of the bullet piece 6 or obliquely upward toward the front side. Alternatively, the longitudinal rib 3E) can be pressed against the front side 1A of the container so that the roll paper 2 in the middle of feeding is not torn, and the roll paper cutting force applied upward to the front side 3B of the cover plate is light even if the paper cut cover plate 3 is light, The cover plate 3 can be prevented from rising, and the cut portions Q of the roll paper and the roll-wrapped film can be reliably cut one after another, and the roll paper feeding portion 2A outside the container by reversing the roll paper inside the container after cutting (pinch allowance 2B ) Can be prevented from being pulled into the container and can be used comfortably.
[0015]
In the third embodiment of the present invention, in order to keep the paper-cutting cover plate 3 in the state of the pressure-closed cover closed in a pressing manner, in the third embodiment of the present invention, as shown in FIG. A protrusion 5 is provided on the outer surface of the protrusion 1, and a closed lid lock portion 5A such as a protrusion with a slope (or a simple protrusion, recess, or hole) formed on the outer surface of the protrusion 5 as shown in FIG. When the paper-cutting cover plate is closed, the lid-locking portions in the order indicated by the arrows in FIG. 8 are closed on the closure-locking portions 5B, such as projections with slopes (or recesses, holes, or simple projections) formed as shown in FIG. By engaging 5A and 5B with the snapping against the elastic force of the projecting piece 5, the above-mentioned pressure-closed closed state can be maintained in a pressing manner. Even if an upward roll paper cutting force is applied due to the paper cutting, the front edge of the paper cutting blade 3 is not pressed without pressing the paper cutting cover plate 3. In the roll paper feed portion 2A can with one hand casually third embodiment the present invention the container is also configured feeding closed lockable roll sheet by which is able to cleave as FIG 2.
[0016]
However, the elastic contact point between the closed lock portions 5A and 5B is determined by considering the variety of paper quality and thickness of the roll paper 2 to be used, and the paper cutting cover plate 3 in the elastic closed state is the lid. The protrusions of the lid lock portions 5A and 5B are positioned by giving a slight allowance so as to lift upward by about 1 mm against the repelling force of the repelling bullet piece 6.
Further, the engagement strength between the respective lid lock portions 5A and 5B is such that the front-side edge of the paper-cutting cover plate 3 can be obtained by maintaining the above-mentioned pressure-tight closed state and feeding the roll paper 2 or the thick roll paper 2 together. Even when a slightly strong upward roll paper cutting force is applied to the paper-cutting cover plate 3 in the closed state, as in the case of cutting at, the paper-cutting cover plate 3 does not float in the illusion as shown in FIG. The paper cutting cover plate 3 is set to such a strength that it can be opened with fingers or the like when desired.
[0017]
【Example】
The protruding surface dimension of the comb-like elastic cutting edge 4B with respect to the front side 3B of the paper cutting cover plate is about 2 to 7 mm, and within this range, a large number of elastic cutting edges 4B have the same dimension or different dimensions for each predetermined number. Preferably, the thickness of each elastic cutting edge 4B is about 0.5 to 3 mm, and the protruding pitch of each cutting edge 4B is preferably about 0.5 to 2 mm.
Further, the front side 3B of the paper cutting cover plate 3 is bent, and the bulging rear side 4A of the band-shaped bent plate 4 having a shape corresponding to the groove is formed in the rear enormous groove 3D formed on the bent front side 3B. May be used, and the comb-like elastic cutting edge 4B may be uniformly exposed from the bent front side 3B so as to prevent the paper cutting cover plate 3 from coming off.
[0018]
Further, by projecting the comb-like elastic cutting edge 4B vertically and vertically, the bending return instantaneous force of each of the cutting edges can be distributed up and down by a small dimension and added to the middle part of the roll paper cutting one after another. It was gentle to fingers and sharper sharpness was obtained for roll paper.
In addition to the above-mentioned projecting means, for example, the projecting piece 6 is made of a strong elastic material such as a spring steel, and the projecting means of the closed-end elastic bullet piece 6 in the second embodiment of the present invention is used as a container rear plate 1C. The inner surface of the container may be protruded by fixing means such as screwing or insert molding, and the protruding piece 6 may be formed integrally with the container rear plate 1C at the time of forming the plastic container 1, for example. The piece 6 may be formed by so-called two-color integral molding in the same mold at the time of molding the container 1 with a strong elastic plastic material, and the projecting piece projecting member 7 in which the projecting piece 6 is integrally projected, The protruding piece 6 may be protruded from the container rear plate 1C by fixing it to the container rear plate 1C by screwing or bonding. Further, the both sides of the roll paper 2 can be fed out and guided by, for example, the protruding pieces 5 provided on both sides of the front portion of the paper cutting cover plate 3.
