【発明の属する技術分野】
この発明は、ロール紙または、これに近似したロール巻きシートやフィルムなどを投げ込み式に収納でき、これらを繰り出して切断できるロール紙繰り出し切断容器に係り、特に本発明では、上記容器に対するロール紙の出し入れとロール紙の繰り出しおよびその切断とを迅速容易、かつ、安全確実に実行可能となしたロール紙繰り出し切断容器に関する。
【０００２】
【従来の技術】
従来の投げ込み収納式のロール紙繰り出し切断容器としては、特開平８−１９６４６７号公報や実開平５−８２３９３号公報記載のものなどが周知である。
これらの各従来の技術は、いずれも、後面を壁面などに定着設置して使用する上部開放の投げ込み収納式の容器内にロール紙を投げ込んで収納した後、このロール紙の繰り出し部分を容器前辺から手前に引き出し定位するとともに、前記容器の後部で枢支した上蓋をその自重または、錘の重力で容器開口縁に被せ、この上蓋下部と容器前辺とで前記繰り出し部分を挟み付けて所望のブレーキを掛け、ロール紙の繰り出し牽引力を所望値になるように設定することで、この繰り出し部分を容器または、上蓋の前辺に横設した刃先でカットできるとしたロール紙繰り出し切断容器である。
【０００３】
【発明が解決しようとする課題】
これら各従来例を初めとして従来の投げ込み収納式のロール紙繰り出し切断容器は、一般に、前記容器の後部で枢支した上蓋をその自重、または錘の重力で容器の開口縁に被せて前記のように使用するものだから、容器開口縁に被せた前記上蓋の下部と容器前辺とで前記繰り出し部分を挟み所望のブレーキを掛けることと、閉蓋状態にある上蓋が妄りに動かないようにするには、上蓋自体または、上記錘付き上蓋をそれぞれ重くする必要があり、ロール紙繰り出し切断容器全体としてもかなりの重量物となってしまうという本質的な問題点が有るし、容器内にロール紙を収納するときやロール紙空心を容器から取り出すときのように、上蓋がほぼ直立の開蓋状態にある場合には、この直立上蓋が極めて倒れ易く、手指で押さえてないと僅かな振動や衝撃などの僅少外乱でも、上記重い上蓋が容器開口縁に向かい大きく「バタン」と倒れ、手指に強い衝撃を与える結果となり、怪我する危険も有るという本質的かつ、大きな問題点が有る。
【０００４】
この他の従来例として、実開昭６１−１０９３９０号公報記載のように、ロール紙繰り出し部分をカットする容器前辺の反対側の容器後側に上蓋を大きく回動させて開蓋する卓上タイプものも有るが、これでは、容器後面を壁面などに定着設置して使用することができず、容器後面を壁面などに定着して使用するには、この従来例公報第５図とその説明のように、容器上蓋を容器本体から分離できる着脱式の被せ蓋とする必要があり、この被せ蓋は分離紛失し易いし、その保管や取り扱いも面倒で厄介であるという本質的かつ、大きな問題点が有る。
【０００５】
この発明は、上記多くの問題点をすべて解決するために、ロール紙または、これに近似したロール巻きシートやフィルムなどを投げ込み収納してこれらを繰り出し切断できるロール紙繰り出し切断容器の軽量化を促進するとともに、容器に対するロール紙の出し入れとロール紙の繰り出しおよびその切断とを迅速容易、かつ、安全確実に実行可能となした投げ込み式のロール紙繰り出し切断容器を多量製造可能とすることを目的とする。
【０００６】
【課題を解決するための手段】
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繰り出し部分を容器前辺から手前に引き出し、その上から容器開口縁に後部枢支の上蓋を被せ、その前辺下面と容器前辺でロール紙を挟圧し、その繰り出し部分を上蓋の前辺刃先で切断可能となしたロール紙繰り出し切断容器を構成するに当たり、前記容器の後面板に前記上蓋の枢支部を経た上蓋後縁に係合する開蓋保持弾片と閉蓋弾圧弾片とをそれぞれ突設し、前記開蓋保持弾片で開蓋状態にある上蓋の前倒を防止し、前記閉蓋弾圧弾片の弾撥力で前記繰り出し途中のロール紙を千切らずに弾圧して繰り出せ、しかも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の容器内引き込みを阻止する程度に前記上蓋を弾圧閉蓋維持するとともに、前記容器の前部端辺内面に形成した閉蓋維持部に上蓋の前部端辺下面に突設した突片の閉蓋維持部を外力で係合させることで、閉じた上蓋にロール紙切断力が加わっても前記弾圧閉蓋維持状態を確保可能と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内にロール紙２を図４のように例えば投げ込み式に収納してこの繰り出し部分２Ａを容器前辺１Ａから手前に引き出し同図４のように定位するとともに、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上蓋３をその後部両側における枢支部３Ｂを支点として図２および図３のように被せ、前記繰り出し部分２Ａを上蓋３の前辺刃先４で図２のように切断可能となしたロール紙繰り出し切断容器を構成するに当たり、本発明では先ず、前記容器１の後面板１Ｃに前記上蓋枢支部３Ｂを経た上蓋後縁３Ｃに係合して開蓋状態を維持するための強弾性プラスチックやばね鋼材などで作った開蓋保持弾片５を図５および図６の取り付け順序を経て図３、図４および図７のように突設し、この弾片５を開いた上蓋３の後縁３Ｃに図４および図８のように係合させることで、開蓋状態にある上蓋３の無用な前倒を防止できるようにする。
【０００８】
さらに、本発明では、前記上蓋後縁３Ｃに係合してこれを手前斜め上向きに弾撥することで、前記枢支部３Ｂを経た上蓋３をシーソー式に弾圧閉蓋状態にするための強弾性プラスチックやばね鋼材などで作った前下がり斜面６Ａ付きの閉蓋弾圧弾片６を上記開蓋保持弾片５と共に図５および図６の取り付け順序を経て図３、図４および図７のように容器１の後面板１Ｃに突設し、この閉蓋弾圧弾片６の弾撥力で上蓋３の前辺下面３Ａ（または、この下面に突設した縦リブ３Ｄ）を容器前辺１Ａにロール紙繰り出し部分２Ａを挟んで図３および図９のように容器前辺１Ａの上面に弾接させることで、前記弾圧閉蓋状態とするのであるが、この弾圧閉蓋強度は、前記繰り出し途中のロール紙２を千切らせずに弾圧して繰り出せ、しかも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の容器内引き込みを阻止する程度の強度にそれぞれ設定する。
【０００９】
次いで、上記弾圧閉蓋状態における上蓋３をロール紙繰り出し部分２Ａの切断時などに妄りに開かないように弾圧閉蓋状態を確保するために、本発明では、図１のように上蓋３の前部端辺下面に突片３Ｅを突設し、この突片３Ｅ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）などの閉蓋維持部３Ｆを前記容器１の前部端辺内面に同図１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）などの閉蓋維持部１Ｅに図１１矢示の順序で各閉蓋維持部１Ｅ、３Ｆ同士をさらに手指などによる外力で各素材の固有弾力に抗してパチンと一発係合させ、閉じた上蓋３にロール紙切断力が加わっても前記弾圧閉蓋維持状態を確保できるようにすることで、上蓋３に加わるロール紙切断力がある程度強くても上蓋３を妄りに浮上させず、前記ロール紙繰り出し部分２Ａを上蓋３を手指などで押さえなくてもその前辺刃先４で上記図２のように確実に片手切断できる本発明によるロール紙繰り出し切断容器を構成できた。
ただし、各閉蓋維持部１Ｅ、３Ｆ同士の弾接係合ポイントは、前記弾圧閉蓋維持状態における上蓋３を前記閉蓋弾圧弾片６の弾撥力に抗して上向きに約１ｍｍ程度、押し上げできるように若干のアロワンスを持たせて位置決めする。
【００１０】
なお、前記開蓋保持弾片５と閉蓋弾圧弾片６との具体的な突設形態の一例として本発明では、上記開蓋保持弾片５と閉蓋弾圧弾片６とをそれぞれ一体突設した図５および図６のような強弾性プラスチック製の弾片形成部材７の係止鉤片７Ａをその固有弾力に抗して図６のような容器後面板１Ｃの係止孔縁１Ｄ内に係入後、この係止孔縁１Ｄに前記係止鉤片７Ａを復帰させ係止することで、容器後面板１Ｃに前記弾片形成部材７を図５および図７のように定着した図１および図２のような本発明によるロール紙繰り出し切断容器を構成することができる。
【００１１】
また、前記開蓋保持弾片５の弾力は、図４のような開蓋状態にある上蓋３が妄りに倒れない程度とし、また閉蓋弾圧弾片６の前下がり斜面６Ａまたは、手前斜め上に弾撥する弾片６自体による上蓋後縁３Ｃに対する上向き弾圧強度、つまり上蓋枢支部３Ｂを経た上蓋３の下向き閉蓋弾圧強度は、前記のように繰り出し途中のロール紙２を千切らずに弾圧して繰り出せ、閉蓋状態にある上蓋３がロール紙切断力では図２のように妄りに浮上せず、しかも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が容器内ロール紙２の反転力で容器内に引き込まれない程度にそれぞれ設定する。
さらに、上記各閉蓋維持部１Ｅ、３Ｆ同士の係合強度は、二枚合わせのロール紙２や厚手のロール紙２を上蓋３の前辺刃先４で切断する時のように、閉蓋状態にある上蓋３がやや強いロール紙切断力では図２のように妄りに浮上せず、かつ、上蓋３を所望時に手指などでは開蓋できる程度に設定する。
なお、上蓋３の前部両側下面に突設した突片３Ｅでロール紙２の両側を繰り出し案内することもできる。
【００１２】
本発明の全体的な構成は以上のようなもので、以下本発明におけるロール紙繰り出し切断容器の実際的な使用動作例について説明する。
先ず、図４ような開蓋保持弾片５の弾力で上蓋後縁３Ｃを支持した上蓋開蓋状態にある容器１内にロール紙２を例えば投げ込み式に収納し、その繰り出し部分２Ａを同図鎖線のように容器前辺１Ａから手前に引き出し定位した後、容器開口縁１Ｂの後部に枢支部３Ｂで枢支した図４のような開蓋状態にある上蓋３を先ず、その上蓋後縁３Ｃに係合している開蓋保持弾片５の弾力に抗し、図８の矢示方向に向かう順序を経て下向きに閉じ始め、上蓋３が閉じ終わる直前になると、今度は、上蓋３とは反対向きにテコの原理により上向き回動する上蓋後縁３Ｃに閉蓋弾圧弾片６がその弾力に抗し、図９の矢示方向に向かう順序を経て係合し、閉蓋弾圧弾片６の前下がり斜面６Ａまたは、手前斜め上に弾撥する弾片６自体が上蓋後縁３Ｃを押し下げる向きに弾接係合した状態で図２、図３のように上蓋３を容器開口縁１Ｂに弾圧して被せ終えることができる。
【００１３】
この被せ終えた上蓋３の後縁３Ｃには、閉蓋弾圧弾片６の前下がり斜面６Ａまたは、手前斜め上に弾撥する弾片６自体によるかなり強い閉蓋弾撥力が引き続き加わっているため、テコの原理により枢支部３Ｂを経た上蓋３は、その自重による閉蓋力と共に上蓋前辺下面３Ａ（または、縦リブ３Ｄの下面）と容器前辺１Ａの上面とで前記ロール紙繰り出し部分２Ａを図３および図８のように引き出し途中の繰り出しロール紙２が千切れない程度に弾圧できるとともに、前記閉蓋弾圧弾片６の閉蓋弾撥力で図２および図３のよう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の容器内引き込みを阻止できる程度にそれぞれ前記上蓋３を弾圧閉蓋維持できる。
【００１４】
また、上記弾圧閉蓋状態は、上蓋３の前部端辺下面に突設した突片３Ｅの閉蓋維持部３Ｆと前記容器１の前部端辺内面に形成した閉蓋維持部１Ｅとをそれぞれ各素材の固有弾力に抗し、さらに手指などの外力で図１１の矢示方向に向かう順序でパチンと一発係合させることで確保することができるから、前記ロール紙２が二枚合わせのロール紙でもその繰り出し部分２Ａを前記上蓋３を持ち上げないでその前辺刃先４で上記図２のように無造作に切断して使用でき、この切断後には、図３のように上記前辺刃先４の下部にロール紙２の次回使用のためのロール紙摘み代２Ｂがてきている。
【００１５】
その後、容器１内のロール紙２を図１０のように使い終え、使用済のロール紙芯管２Ｃを容器１内から取り除き、新しいロール紙２を容器１内に投げ込み収納するには、同図１０のような閉蓋状態にある上蓋３をその自重および前記閉蓋弾圧弾片６および開蓋保持弾片５の各弾力および上蓋３の前記閉蓋維持部３Ｆと容器１の前記閉蓋維持部１Ｅとの各係合弾力にそれぞれ抗し、手指などで図１１の矢示と反対方向の順序を経て開け始め、次いで、図９および図８における各矢示方向とは反対向きの順序を経て図１および図４のようにほぼ直立開蓋することができ、この開蓋状態にある上蓋３は前記のように、その上蓋後縁３Ｃが開蓋保持弾片５の弾力に抗して弾撥支持状態となるから、上記開蓋状態にある上蓋３は、妄りに倒れることはなく安心して容器１内の空の芯管２Ｃを取り出し、新しいロール紙２と交換でき、その繰り出し部分２Ａを前記のように容器前辺１Ａから手前に引き出し定位した後、容器開口縁１Ｂに上蓋３を前記図３のように被せることで、上記新しいロール紙２を前記と同様に使用できる。
【００１６】
【実施例】
本発明に用いる前記開蓋保持弾片５および閉蓋弾圧弾片６との突設手段は、前記のような突設手段以外に、例えば上記各弾片５、６をゼンマイ鋼などの強弾性材で作り、これらをそれぞれ容器後面板１Ｃの内面にねじ止めや接着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、上記各弾片５、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、強弾性プラスチック材で二色一体成形により突設してもよく、さらに、上記各弾片５、６をそれぞれ一体突設した弾片形成部材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、上記各弾片５、６を容器後面板１Ｃに突設してもよい。
【００１７】
なお、前記容器１と上蓋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切断容器となるし、また前記上蓋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３Ｄ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より一層確実になったし、前記上蓋３の前辺刃先４としては、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櫛歯状に射出成形した柔軟な刃先板を取着して用いてもよい。
【００１８】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roll paper feeding and cutting container capable of storing roll paper or a roll wound sheet or film similar thereto in a throw-in manner, and feeding and cutting these roll paper. The present invention relates to a roll paper feeding / cutting container capable of performing loading / unloading, feeding of roll paper, and cutting thereof quickly, easily, and safely and reliably.
[0002]
[Prior art]
As a conventional throw-in storage type roll paper feeding and cutting container, those described in JP-A-8-196467 and JP-A-5-82393 are well known.
In each of these conventional techniques, after the roll paper is thrown and stored in a throw-away storage container having an open top which is used by fixing the rear surface to a wall or the like, and then, the payout portion of the roll paper is placed in front of the container. The container is pulled out from the side and positioned in front, and the upper lid pivotally supported at the rear of the container is put on the container opening edge by its own weight or the weight of the weight, and the extended portion is sandwiched between the lower part of the upper lid and the front of the container. By applying the brake and setting the roll paper feeding traction force to a desired value, the roll portion can be cut by a container or a cutting edge provided laterally on the front side of the upper lid. .
[0003]
[Problems to be solved by the invention]
In general, the conventional throw-in type roll paper feeding / cutting container including each of these conventional examples generally covers the opening edge of the container by its own weight or the gravity of the weight on the opening edge of the container, as described above, with the upper lid pivotally supported at the rear of the container. Therefore, it is necessary to apply the desired brake by sandwiching the extended portion between the lower part of the upper lid over the opening edge of the container and the front side of the container, and to prevent the upper lid in the closed state from moving unnecessarily. It is necessary to make the upper lid itself or the upper lid with weight each heavy, and there is an essential problem that the roll paper feeding and cutting container as a whole becomes considerably heavy, and the roll paper is placed in the container. When the top lid is in an almost upright open state, such as when storing or removing the roll paper core from the container, this upright top lid is extremely easy to fall down, and may be slightly Even slight disturbance such as dynamic or impact, the heavy lid collapse largely toward the container opening edge "slam", results in a strong shock to the hands, essential and that there is also a risk of injury, major problems there.
[0004]
As another conventional example, as described in Japanese Utility Model Application Laid-Open No. 61-109390, a tabletop type in which the upper lid is largely rotated and opened to the rear side of the container opposite to the front side of the container where the roll paper feeding portion is cut. However, in this case, it is impossible to fix the rear surface of the container on a wall or the like and use it. In order to fix the rear surface of the container on a wall or the like and use it, refer to FIG. As described above, it is necessary to make the container top cover a detachable cover that can be separated from the container body, and this cover is easy to separate and lose, and its storage and handling is cumbersome and troublesome, and is a major problem. There is.
[0005]
In order to solve all of the above-mentioned many problems, the present invention promotes weight reduction of a roll paper feeding / cutting container capable of throwing in and storing roll paper or a roll-wound sheet or film similar thereto and feeding and cutting them. In addition, it is an object of the present invention to be able to mass-produce a throw-in type roll paper feeding / cutting container capable of quickly and easily and safely and reliably performing the feeding / unloading of roll paper into / from the container and the feeding / cutting of the roll paper. I do.
[0006]
[Means for Solving the Problems]
The object of the present invention described above is to pull out the unwinding portion of the roll paper accommodated in the container having an open top from the front side of the container toward the front side, cover the opening edge of the container from above with a rear pivot upper lid, In forming a roll paper feeding cutting container in which the roll paper is squeezed at the front edge of the container and the feeding portion can be cut by the cutting edge of the front edge of the upper lid, after the upper lid has passed through the pivot portion of the upper lid on the rear plate of the container. The open-holding elastic piece and the closed-open elastic pressure piece engaging with the edge are respectively protruded to prevent the upper lid in the open state with the open-close holding elastic piece from falling forward. The upper cover is resiliently closed to the extent that the roll paper in the middle of the feeding is resiliently pressed by the repelling force without shredding, and is prevented from being pulled out of the roll paper feeding portion outside the container due to the reversal of the roll paper inside the container after cutting. Keep the lid and the front of the container Even if a roll paper cutting force is applied to the closed upper lid by engaging the closed lid maintaining section of the protruding piece protruding from the lower surface of the front end side of the upper lid with the closed lid maintaining section formed on the inner surface of the upper lid by external force. This has been achieved by making it possible to ensure the state of maintaining the suppressed pressure lid.
[0007]
BEST MODE FOR CARRYING OUT 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 roll paper 2 is placed in a top-open container 1 made of metal, plastic, or the like which is fixed and installed on the wall of a toilet or the like and has a substantially circular side. As shown in FIG. 4, for example, the container is housed in a throw-in manner, and the feeding portion 2A is pulled out from the front side 1A of the container to the front, and is positioned as shown in FIG. The upper cover 3 made in a substantially arc shape is covered as shown in FIGS. 2 and 3 with the pivot portions 3B on both sides of the rear portion as fulcrums, and the extended portion 2A can be cut with the front edge 4 of the upper cover 3 as shown in FIG. In forming the rolled paper feeding and cutting container, in the present invention, first, a strong force for engaging the rear cover 1C of the container 1 with the upper cover rear edge 3C passing through the upper cover pivot 3B to maintain the open state. Bullet 3 and 4 through FIG. 5, FIG. 6, and FIG. 6. The lid-holding elastic piece 5 made of plastic, spring steel, or the like is protruded from the upper lid 3 with the elastic piece 5 opened. By engaging the rear edge 3C as shown in FIGS. 4 and 8, it is possible to prevent the upper lid 3 in the opened state from being unnecessarily tilted forward.
[0008]
Further, in the present invention, the upper lid rear edge 3C is engaged with the upper lid rearward and repelled obliquely upward toward the front, so that the upper lid 3 that has passed through the pivotal support 3B is brought into a seesaw type elastically closed state. As shown in FIGS. 3, 4 and 7, through a mounting sequence of FIGS. 5 and 6, a closed resilient elastic piece 6 having a downward slope 6A made of plastic, spring steel or the like and having the above-mentioned open retaining elastic piece 5 is attached. The lower surface 3A of the front side of the upper lid 3 (or the vertical rib 3D protruding from the lower surface) is rolled to the front side 1A of the container by projecting from the rear plate 1C of the container 1 and by the resilience of the elastic member 6 for closing the cover. As shown in FIGS. 3 and 9, the paper feeding portion 2A is sandwiched between the paper feeding portion 2A and the upper surface of the container front side 1A to make the resiliently closed state. The roll paper 2 can be rolled out without shredding, and the volume after cutting To set to the strength enough to prevent retraction vessel inner roll paper container outside the roll paper feeding portion 2A by inversion.
[0009]
Next, in order to secure the resiliently closed state so that the upper lid 3 in the resiliently closed state is not opened unnecessarily when the roll paper feeding portion 2A is cut or the like, in the present invention, as shown in FIG. A protruding piece 3E protrudes from the lower surface of the end of the container, and a closed-close maintaining section 3F such as a beveled projection (or a simple projection, recess or hole) formed on the protruded piece 3E is attached to the inner surface of the front end of the container 1. In FIG. 11, each of the lid maintaining parts 1E and 3F is further joined with fingers and the like in the order shown by the arrow in FIG. 11 to the lid maintaining part 1E such as a beveled projection (or a mere projection, recess, or hole) formed as shown in FIG. The outer cover 3 is made to engage once with a snap against the inherent elasticity of each material by the external force of the upper cover 3 so that even if a roll paper cutting force is applied to the closed upper cover 3, the state of maintaining the elastic pressure closed cover can be ensured.
