Description

【０００１】
【発明の属する技術分野】
この発明は、ポット、水さし、びん、コップ等の容器の内面を摺洗するのに好適に用いられる、或いはトイレブラシとして好適に用いられる摺洗用ブラシに関する。
【０００２】
【従来の技術】
従来、この種の摺洗用ブラシとしては、繊維を針金の間に挟んで撚り合わせることにより棒状に形成したものが一般的であったが、その先端の針金が突出しているためコップ底等の被摺洗面に傷を付けてしまうという欠点があった。
【０００３】
そこで、このような欠点を解消するものとして、上記のようにして形成した棒状ブラシの先端部を半円状あるいはＵ字状に湾曲せしめて折り返し針金突出部を内側に巻き込んだものが上市されているが、針金突出部が遊端となっているため、被摺洗面に先端部を強く押し当てて摺洗を繰り返すうちに変形して針金突出部が外面に露出し被摺洗面を傷つけるおそれがあるという問題があった。また、湾曲により先端部の繊維密度は低くなっており、そのためこの先端部における摺洗能力は低く、容器の底部の洗浄を十分に行えるものではなかった。更に、先端部の繊維密度が低いために繊維が屈撓しやすく、被摺洗面と針金が接触して、不快音を発生したりすることが多々あった。
【０００４】
そこで、上記の問題点を一挙に解決し得るものとして、本出願人は先に、２条の撚り合わされた針金の間に多数の繊維が連続状に挟着固定された２本の棒状ブラシ本体の基端側の針金突出部で形成される柄取付部に把柄が取り付けられる一方、前記２本の棒状ブラシ本体のそれぞれの先端側が相互に対峙する態様で湾曲され、これら先端側の針金突出部が繊維束植設基片を介して相互に接合されるとともに、該基片に繊維束が三次元放射状に植設された摺洗用ブラシを提案している（特許第２９４８１６０号公報）。これによれば、針金突出部が露出しないので被摺洗面を傷つけることがなく、また先端の基片に多数の繊維束が植設されているので摺洗能力に優れ、かつ繊維束の剛性により基片が被摺洗面に接触することもなくて不快音の発生が防止される。
【０００５】
【発明が解決しようとする課題】
しかしながら、上記構成に係る摺洗用ブラシは、製作するのに２本の棒状ブラシ本体、先端部用ブラシ部材及び把柄の４つの構成部品を必要とし、部品点数が多いという問題があった。
【０００６】
また、２本の棒状ブラシ本体のそれぞれの先端側の針金突出部を繊維束植設基片に接合する必要があるが、強固に接合するためには、針金突出部を接着剤を用いて基片の孔に嵌合接着するか、あるいは針金突出部を、基片を構成する合成樹脂の溶融温度以上に加熱された状態で基片の孔に嵌合溶着させる等、このような接着、溶着等の煩雑な接合工程が必要であり、そのために製作工程数が多くなり、製作時間もかかり、ひいてはコストを増大させるという問題もあった。
【０００７】
更に、棒状ブラシ本体の針金突出部と繊維束植設基片とを接着、溶着等により接合しているものであるので、使用中において特に強い無理な力が該接合部に負荷されるようなことがあると、繊維束植設基片と棒状ブラシ本体の接合状態が損なわれてしまうことが懸念される。
【０００８】
この発明は、かかる技術的背景に鑑みてなされたものであって、構成部品点数を削減できる上に、接着、溶着等の煩雑な工程を要せずして繊維束植設基片と棒状ブラシ本体の一体化が可能となって製作工程及び製作時間が少なくて済み低コストであり、かつ強い無理な力が加わったとしても繊維束植設基片が離脱してしまうことがなく、また被摺洗面を傷つけることがなく、摺洗能力に優れると共に、不快音の発生もない摺洗用ブラシを提供することを目的とする。
【０００９】
【課題を解決するための手段】
上記目的を達成するために、本発明者は鋭意研究の結果、１本の棒状ブラシ本体を繊維束が植設された基片の貫通孔に挿通配置せしめて、棒状ブラシ本体の中央部を、該貫通孔の長さ方向の一部に形成された狭小開口部によって緊締状態に拘束するものとし、かつ貫通孔の両端の開口部近傍位置においてブラシ本体を屈曲させてブラシ本体の両端側で形成される柄取付部に把柄を取り付けた構成とすることにより、上記所望の摺洗用ブラシが得られることを見出すに至り、この発明を完成したものである。
【００１０】
即ち、この発明に係る摺洗用ブラシは、２条の撚り合わされた針金の間に多数の繊維が連続状に挟着固定された棒状ブラシ本体と、貫通孔が設けられた繊維束植設基片の外表面に繊維束が三次元放射状に植設された先端部用ブラシ部材と、把柄とを備えてなり、前記繊維束植設基片の貫通孔の周壁面から１ないし複数のリブが内方に突設されることによって、該貫通孔の長さ方向の一部に通路断面積の小さくなされた狭小開口部が形成される一方、前記棒状ブラシ本体が前記繊維束植設基片の貫通孔に挿通されて該棒状ブラシ本体の中央部が前記狭小開口部によって緊締状態に拘束されると共に、前記貫通孔の両端の開口部近傍位置において前記棒状ブラシ本体が屈曲されて、該ブラシ本体の両端側の針金突出部で形成される柄取付部に把柄が取り付けられてなることを特徴とするものである。
【００１１】
この摺洗用ブラシはいずれの部位においても針金突出部が露出することがないから、摺洗時に被摺洗面を傷つけることがない。また先端側の植設基片に多数の繊維束が植設されて繊維密度が大きく、かつ三次元放射状に植設されているから、摺洗能力に優れる。更に、個々の繊維束は、繊維が束になっているから剛性を有しており、従って繊維束は屈撓することがなく、被摺洗面を強い力で擦り洗うことができ、容器の底部に汚れがこびり付いているような場合にも簡単に洗い落とすことができる。また、この時繊維束の剛性により被摺洗面と基片とが接触することもないから、不快音の発生もない。このような先端部用ブラシ部材と、ブラシ本体の相乗作用により、例えば容器であれば、その内面全てを余すことなく摺洗できる。
【００１２】
また、１本の棒状ブラシ本体の中央部を繊維束植設基片の貫通孔に挿通配置せしめて、この状態でブラシ本体を屈曲することにより構成されるものであり、従来のように棒状ブラシ本体を２本必要とするものではなく１本で済むので、構成部品点数を削減できる利点がある。そしてブラシ本体は繊維束植設基片の貫通孔の狭小開口部によって緊締状態に拘束されているので、繊維束植設基片がブラシ本体に対して安定状態に固定され、摺洗時における植設基片の位置ずれ、ガタツキ等が効果的に防止される。また、棒状ブラシ本体が貫通孔の両端の開口部近傍位置において屈曲されており、該両端の屈曲部間に基片が挟まれて配置されるので、貫通孔の軸線に沿う方向への植設基片の移動が確実に阻止される。前記狭小開口部は貫通孔の長さ方向の一部に形成されており、貫通孔の全体が狭小となされているものではないので、植設基片の貫通孔へのブラシ本体の挿通がスムーズなものとなり非常に製作が容易となる。このように、繊維束植設基片と棒状ブラシ本体の一体化を、接着、溶着等の煩雑な工程を要せずしてなし得るので、製作工程及び製作時間が少なくて済み低コストで製作できる。更に、棒状ブラシ本体を繊維束植設基片の貫通孔に挿通配置せしめて一体化しているから、強い無理な力が加わったとしても繊維束植設基片が離脱してしまうことがない。
【００１３】
上記繊維束植設基片の貫通孔の両端開口部のそれぞれの周縁部の一部に切欠凹部が設けられて、該切欠凹部に棒状ブラシ本体の針金が嵌まり込んで配置されているのが好ましい。基片の切欠凹部にブラシ本体の針金が嵌まり込んで配置されているから、摺洗時における貫通孔の軸線を中心とした植設基片の回転ずれ移動が確実に防止され、被摺洗面を一層強い力で確実に擦り洗うことができ、例えば容器の底部にこびり付いた汚れも確実に洗い落とすことができる。
【００１４】
また、繊維束植設基片の貫通孔の周壁面から複数のリブが相互に対向して突設されることによって狭小開口部が形成されるようになされているのが好ましい。複数のリブが相互に対向して突設配置されることによって、狭小開口部において棒状ブラシ本体が一層強い締め付け力でもって緊締状態に拘束されるので、ブラシ本体に対してより安定した状態で繊維束植設基片の固定がなされ得る。
【００１５】
貫通孔の両端開口部と向き合うリブ側面のうち少なくとも一側面が、貫通孔の径内方に向けて内向きに傾斜した傾斜面に形成されているのが好ましい。リブの側面がこのような傾斜面に形成されることによって植設基片の貫通孔へのブラシ本体の挿通がよりスムーズなものとなる。
【００１６】
また、ブラシ本体における繊維束植設基片側の先端部が屈曲または湾曲されることによって、先端部用ブラシ部材がブラシ本体に対して起き上がり状に配置されているのが好ましい。底部が拡がった形態のポット等の容器は、一般にその底面や底部側内周側面の汚れを洗い落とすのが容易ではないが、上記構成では先端部用ブラシ部材が起き上がり状に配置されているので、容器の底面や底部側内周側面等にこびり付いた汚れも簡単に摺洗することが可能となる。また、起き上がり状配置となされることで、入り込んだ箇所の摺洗も容易に行うことができるので、トイレブラシとしても好適である。
【００１７】
【発明の実施の形態】
この発明の一実施形態に係る摺洗用ブラシ（１）を図１〜３に示す。これらの図において、（２）は棒状ブラシ本体、（３）先端部用ブラシ部材、（４）は針金、（５）は把柄であり、前記先端部用ブラシ部材（３）は繊維束植設基片（７）と多数の繊維束（８）…より構成される。
【００１８】
繊維束植設基片（７）は、図４に示すように、底面側が平坦面に形成され、上面側が略球面状となされたやや横長の立体形状を有する合成樹脂成形品からなり、その長さ方向に沿って貫通孔（１０）が穿設されている。この貫通孔（１０）の中央部には、その周壁面から一対のリブ（１１）（１１）が相互に対向して突設され、これにより貫通孔（１０）の長さ方向の一部に通路断面積の小さくなされた狭小開口部（１２）が形成されている。前記リブ（１１）（１１）の幅方向両側面は、図４（ホ）に示すように貫通孔（１０）の径内方に向けて内向きに傾斜した傾斜面に形成されている。
【００１９】
前記繊維束植設基片（７）の貫通孔（１０）の両端開口部のそれぞれの周縁部の一部には切欠凹部（２０）（２０）が設けられている。即ち、前記両端開口部の内周壁面の一部からその背面にある平坦状底面にかけて凹溝状の切欠凹部（２０）（２０）が形成されている。この切欠凹部（２０）の溝幅は前記撚り合わされた針金（４）（４）で形成される外径よりも若干大きくなるように設定されており、この切欠凹部（２０）に棒状ブラシ本体（２）の針金（４）（４）が嵌まり込み得るようになされている。
【００２０】
前記繊維束植設基片（７）における略球面状の上面側から背面側にかけて繊維束を植設するための植設孔（７ａ）…が多数穿設され、該植設孔（７ａ）…に多数の繊維束（８）…が接着剤により接着固定され、これら（７）（８）…によって先端部用ブラシ部材（３）が構成されている。この植設孔（７ａ）の穿設方向は、いずれの植設孔（７ａ）においても、繊維束植設基片（７）の表面に対してほぼ垂直な方向に向かうように設定されており、従って繊維束（８）…は三次元放射状に植設される。
【００２１】
前記棒状ブラシ本体（２）は、２本の針金（４）（４）の間に多数本の繊維（６）…を挟んだ状態で針金（４）（４）を撚り合わせることによって形成されたものである。
【００２２】
また、把柄（５）は、長尺の樹脂成形品からなり、その先端頂部に２つの嵌合孔（５ａ）（５ａ）が穿設される一方、基端側には引っかけて吊り下げるためのフック（図面では省略）が付設されている。
【００２３】
この発明の摺洗用ブラシ（１）は、上記先端部用ブラシ部材（３）、棒状ブラシ本体（２）および把柄（５）を備えてなるものであり、これらが以下のような態様で一体化されたものである。
【００２４】
即ち、この発明の摺洗用ブラシ（１）は、前記棒状ブラシ本体（２）が前記繊維束植設基片（７）の貫通孔（１０）に挿通配置されて、該棒状ブラシ本体（２）の中央部が貫通孔（１０）の狭小開口部（１２）によって緊締状態に拘束される（図２参照）と共に、前記貫通孔（１０）の両端の開口部近傍位置において前記棒状ブラシ本体（２）が屈曲され、更に植設基片（７）の切欠凹部（２０）（２０）にブラシ本体（２）の針金（４）（４）がそれぞれ嵌まり込んで配置されて（図３参照）、ブラシ本体（２）がその中央部において折り返し状となされ、ブラシ本体（２）の両端側の針金突出部で形成される柄取付部に把柄（５）が取り付けられてなるものである。前記把柄（５）の取り付けは、前記両端側の針金突出部を、それぞれ接着剤を用いて把柄（５）の嵌合孔（５ａ）（５ａ）に嵌合接着することによりなされたものである。なお、この取り付けは、針金突出部の一方が他方にねじり止められて１つの柄取付部が形成され、該柄取付部が把柄の頂部に穿設された１つの嵌合孔に嵌合固定されることによってなされるものであっても良い。
【００２５】
上記摺洗用ブラシ（１）では、ブラシ本体（２）が繊維束植設基片（７）の貫通孔（１０）の狭小開口部（１２）によって緊締状態に拘束されているので、繊維束植設基片（７）がブラシ本体（２）に対して安定状態に固定される。従って、摺洗時において植設基片（７）即ち先端部用ブラシ部材（３）の位置ずれやガタツキ等が効果的に防止されるので、被摺洗面を強い力で確実に擦り洗うことができる。また、棒状ブラシ本体（２）が貫通孔（１０）の両端の開口部近傍位置において屈曲されており、該両端の屈曲部間に基片（７）が挟まれて配置されているので、貫通孔（１０）の軸線に沿う方向への植設基片（７）の移動が確実に阻止される。更に、植設基片（７）の切欠凹部（２０）にブラシ本体（２）の針金（４）（４）が嵌まり込んで配置されているので、摺洗時において貫通孔（１０）の軸線を中心とした植設基片（７）の回転ずれ移動が確実に防止され、ひいては被摺洗面を一層強い力で確実に擦り洗うことができるものとなる。
【００２６】
前記狭小開口部（１２）は、貫通孔（１０）の全体ではなくその長さ方向の一部に形成されているので、貫通孔（１０）へのブラシ本体（２）の挿通がスムーズなものとなる。更に、貫通孔（１０）の両端開口部と向き合うリブ（１１）（１１）の幅方向側面が、貫通孔（１０）の径内方に向けて内向きに傾斜した傾斜面に形成されているから、貫通孔（１０）へのブラシ本体（２）の挿通がより一層スムーズなものとなり、ひいては製作が容易になると共に、製作時間も一層短縮される。
【００２７】
このように、繊維束植設基片（７）とブラシ本体（２）の一体化を、接着、溶着等の煩雑な工程を要せずして行うことができるので、製作工程及び製作時間が少なくて済み低コストで製作できる。また、ブラシ本体（２）としては２本必要とせず１本で構成できるので、部品点数を削減できる利点もある。更に、ブラシ本体（２）を繊維束植設基片（７）の貫通孔（１０）に挿通配置せしめた構成であるから、強い無理な力が加わったとしても繊維束植設基片（７）が離脱してしまうこともない。
【００２８】
更に、本実施形態においては、ブラシ本体（２）における繊維束植設基片（７）側の先端部が屈曲されることによって、繊維束（８）…が植設された基片（７）、即ち先端部用ブラシ部材（３）が起き上がり状に配置されているので、口部よりも底部が拡くなった底拡がり状の容器であっても、その底面や底部側内周側面等にこびり付いた汚れをも簡単に摺洗することができる。また、先端部用ブラシ部材（３）が起き上がり状に配置されているので、入り込んだ箇所の摺洗も容易に行うことができ、従ってトイレブラシとしても好適なものとなる。
【００２９】
なお、上記実施形態では、２個のリブ（１１）（１１）が相互に対向して突設されることによって狭小開口部（１２）が形成されるようになされているが、狭小開口部（１２）を形成するためのリブ（１１）の数は特にこれに限定されるものではなく、１個であっても良いし、あるいは３個以上であっても良い。ただ、狭小開口部（１２）においてブラシ本体（２）を一層強い締め付け力でもって緊締状態に拘束する観点から、複数のリブが相互に対向して突設されることによって狭小開口部（１２）が形成されるようになされているのが好ましい。
【００３０】
また、リブ（１１）の形状は特に限定されず、例えば図６に示すような断面三角形状であっても良い。あるいは、リブが貫通孔（１０）の周壁面に沿って周回して連なりリング状に形成されていても良い。
【００３１】
また、上記実施形態では、貫通孔（１０）の１箇所に狭小開口部（１２）が形成されているが、特にこれに限定されるものではなく、貫通孔（１０）の長さ方向に相互に所定間隔をあけて複数の狭小開口部（１２）が形成されていても良い。このように狭小開口部（１２）を複数設けた場合には、ブラシ本体（２）の拘束箇所が２以上の複数となるので、より安定した状態で基片（７）とブラシ本体（２）の一体化固定を行うことができる。
【００３２】
また、上記実施形態では、繊維束植設基片（７）の素材として合成樹脂を用いているが、特にこれに限定されるものではなく、例えば木、金属、セラミックスなども選択することができる。
【００３３】
更に、繊維束植設基片（７）の形状、大きさ等も上記実施形態のものに特に限定されるものではなく、その用途等に応じて適宜設計変更して構成されるものであることは言うまでもない。
【００３４】
図５は、この発明の別の実施形態に係る摺洗用ブラシの先端部用ブラシ部材（３）及びその近傍を示すものであり、繊維束植設基片（７Ｂ）の形状が前記実施形態とは異なるものであって、これ以外の構成については前記実施形態と同様であり、同様である構成部分については前記実施形態と同一の符号を付してその説明は省略する。この実施形態の繊維束植設基片（７Ｂ）は、前記繊維束植設基片（７）における切欠凹部（２０）より背面側の底面部が下方に延長されて底部突出部（４０）が突設形成されてなるものであり、該底部突出部（４０）の背面側にも繊維束（８）…が植設されたものである。なお、この底部突出部（４０）の背面側は、放射状の植設がなされるように傾斜曲面となされている。
【００３５】
本構成によれば、底部突出部（４０）の背面側にも繊維束（８）…が植設されることによって、ブラシ（１）の背面側における先端部用ブラシ部材（３）の繊維束（８）…とブラシ本体（２）の繊維（６）…との間に間隙を生じることなく両者（３）（２）の繊維群が連なった態様で配置されるので、その分摺洗能力を向上させることができる。
【００３６】
【発明の効果】
以上のように、この発明の摺洗用ブラシは、針金突出部が露出しないので被摺洗面を傷つけることがなく、先端側の植設基片に多数の繊維束が植設されて繊維密度が大きい上に三次元放射状に植設されているので摺洗能力に優れ、また該繊維束はその剛性により屈撓することがなくて被摺洗面と基片とが接触しないので不快音の発生もない。
【００３７】
また、棒状ブラシ本体を２本必要とせず１本で構成できるので、構成部品点数を削減できる利点がある。ブラシ本体が基片の貫通孔の狭小開口部によって緊締状態に拘束されているので、基片がブラシ本体に対して安定状態に固定され、摺洗時における基片の位置ずれ等を効果的に防止でき、ひいては被摺洗面を強い力で確実に摺洗することができる。また狭小開口部は貫通孔の長さ方向の一部に形成されているので、基片の貫通孔への挿通がスムーズであり非常に製作が容易となる。このように、基片とブラシ本体の一体化を、接着、溶着等の煩雑な工程を要せずしてなし得るので、製作工程及び製作時間が少なくて済み、ひいては低コストで製造できる。更に、ブラシ本体を基片の貫通孔に挿通配置せしめた構成であるから、強い無理な力が加わっても基片が離脱することもない。
【００３８】
繊維束植設基片の貫通孔の両端開口部のそれぞれの周縁部の一部に切欠凹部が設けられて、該切欠凹部に棒状ブラシ本体の針金が嵌まり込んで配置されている場合には、摺洗時における基片の移動を確実に防止できるので、被摺洗面を一層強い力で確実に摺洗することができる。
【００３９】
繊維束植設基片の貫通孔の周壁面から複数のリブが相互に対向して突設されることによって狭小開口部が形成されている場合には、ブラシ本体に対してより安定した状態で基片を固定させることができ、被摺洗面をより一層強い力で確実に摺洗することができる。
【００４０】
貫通孔の両端開口部と向き合うリブ側面のうち少なくとも一側面が、貫通孔の径内方に向けて内向きに傾斜した傾斜面に形成されている場合には、基片の貫通孔へのブラシ本体の挿通がよりスムーズとなるので、一層製作時間を短縮できて、一層の低コスト化を図り得る。
【００４１】
ブラシ本体における繊維束植設基片側の先端部が屈曲または湾曲されることによって、先端部用ブラシ部材がブラシ本体に対して起き上がり状に配置されている場合には、底拡がり状の容器であっても、その底面や底部側内周側面等にこびり付いた汚れを簡単に摺洗することができる。また、入り込んだ箇所の摺洗も容易であるのでトイレブラシとしても好適なものとなる。

BACKGROUND OF THE INVENTION
The present invention relates to a brush for scrubbing which is preferably used for scrubbing the inner surface of a container such as a pot, a paddle, a bottle, a cup or the like, or preferably used as a toilet brush.
[0002]
[Prior art]
Conventionally, as this type of brush for scrubbing, it was common to form a rod by sandwiching fibers between wires and twisting them, but since the wire at the tip protrudes, such as a cup bottom There was a drawback that the surface to be washed was scratched.
[0003]
Therefore, as a solution to such a drawback, a product in which the tip of the rod-shaped brush formed as described above is bent into a semicircular shape or a U shape and the folded wire protruding portion is wound inside is marketed. However, since the wire protrusion is a free end, there is a risk that the wire protrusion will be exposed to the outer surface and be damaged by repeatedly pressing the tip against the surface to be cleaned and repeatedly washing. There was a problem that there was. Further, the fiber density at the tip portion is lowered due to the curvature, and therefore, the sliding ability at the tip portion is low, and the bottom portion of the container cannot be sufficiently washed. Furthermore, since the fiber density at the tip portion is low, the fiber is likely to bend, and the surface to be washed and the wire come into contact with each other, often causing unpleasant noise.
[0004]
Therefore, as a solution to the above-mentioned problems, the present applicant has previously described two rod-shaped brush bodies in which a large number of fibers are continuously sandwiched and fixed between two twisted wires. A handle is attached to a handle attaching portion formed by a wire protrusion on the base end side of the wire, while the tip ends of the two rod-shaped brush bodies are curved so as to face each other, and the wire protrusions on the tip side Has been proposed to be bonded to each other through a fiber bundle planting base piece, and a brush for washing with a fiber bundle planted in a three-dimensional radial pattern on the base piece (Japanese Patent No. 2948160). According to this, since the wire protruding portion is not exposed, the surface to be washed is not damaged, and since a large number of fiber bundles are implanted on the base piece at the tip, the washing performance is excellent, and the rigidity of the fiber bundles The base piece does not come into contact with the surface to be washed and the generation of unpleasant noise is prevented.
[0005]
[Problems to be solved by the invention]
However, the brush for scrubbing according to the above configuration requires four component parts, that is, two rod-shaped brush bodies, a tip brush member, and a handle, and has a problem that the number of parts is large.
[0006]
In addition, it is necessary to join the wire protrusions on the tip side of each of the two rod-shaped brush bodies to the fiber bundle planting base piece, but in order to join them firmly, the wire protrusions are bonded using an adhesive. Such adhesion and welding, such as fitting and welding to the hole of the piece, or fitting and welding the wire protrusion to the hole of the base piece while being heated to the melting temperature or higher of the synthetic resin constituting the base piece Therefore, there is a problem that the number of manufacturing steps is increased, the manufacturing time is increased, and the cost is increased.
[0007]
Furthermore, since the wire protrusion of the rod-shaped brush body and the fiber bundle planting base are joined by bonding, welding, etc., a particularly strong and unreasonable force is applied to the joint during use. If this is the case, there is a concern that the bonding state between the fiber bundle planting base piece and the rod-shaped brush body may be impaired.
[0008]
The present invention has been made in view of such a technical background, and can reduce the number of components and can eliminate the need for complicated steps such as adhesion and welding, and a fiber bundle planting base piece and a rod-shaped brush. The main body can be integrated, the production process and production time are reduced, and the cost is low. Even if a strong force is applied, the fiber bundle planting base is not detached and An object of the present invention is to provide a brush for washing that does not damage the washing surface, has excellent washing performance, and does not generate unpleasant noise.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, as a result of earnest research, the present inventor has inserted and arranged one rod-shaped brush body into the through-hole of the base piece in which the fiber bundle is implanted, and the central portion of the rod-shaped brush body, Constrained in a tightened state by narrow openings formed in a part of the length of the through hole, and formed at both ends of the brush body by bending the brush body at positions near the openings at both ends of the through hole. The present invention has been completed by finding that the desired brush for scrubbing can be obtained by adopting a structure in which a handle is attached to the handle attaching portion.
[0010]
That is, the brush for scrubbing according to the present invention has a rod-shaped brush body in which a large number of fibers are sandwiched and fixed between two twisted wires, and a fiber bundle planting base provided with a through hole. A tip end brush member in which fiber bundles are radially implanted on the outer surface of the piece, and a handle, and one or more ribs are formed from the peripheral wall surface of the through-hole of the fiber bundle implantation base piece. By projecting inwardly, a narrow opening having a small passage cross-sectional area is formed in a part of the length direction of the through hole, while the rod-shaped brush body is formed of the fiber bundle planting base piece. The central portion of the rod-shaped brush body inserted through the through-hole is restrained in a tightened state by the narrow opening, and the rod-shaped brush main body is bent at positions near the openings at both ends of the through-hole. Handles on the handle attachment part formed by the wire protrusions on both ends of the It is attached composed is characterized in.
[0011]
In this brush for washing, since the wire protrusion is not exposed at any part, the surface to be washed is not damaged at the time of washing. Moreover, since many fiber bundles are planted on the planting base piece on the distal end side, the fiber density is large, and the plant is radially planted. Furthermore, the individual fiber bundles have rigidity because the fibers are bundled, and therefore the fiber bundles do not bend and the surface to be washed can be scrubbed with a strong force. It can be easily washed off even if it is dirty. Further, at this time, the surface to be washed and the base piece do not come into contact with each other due to the rigidity of the fiber bundle, so that no unpleasant noise is generated. Due to the synergistic action of the brush member for the tip portion and the brush body, for example, if it is a container, it can be washed without leaving the entire inner surface.
[0012]
Further, the center portion of one rod-shaped brush body is inserted and arranged in the through hole of the fiber bundle planting base piece, and the brush body is bent in this state. Since only one main body is required instead of two, there is an advantage that the number of components can be reduced. Since the brush body is constrained in a tightened state by the narrow opening of the through hole of the fiber bundle planting base piece, the fiber bundle planting base piece is fixed in a stable state with respect to the brush body, and is planted at the time of washing. Misalignment of the base piece, rattling and the like are effectively prevented. In addition, since the rod-shaped brush body is bent in the vicinity of the opening portions at both ends of the through-hole, and the base piece is sandwiched between the bent portions at both ends, it is implanted in the direction along the axis of the through-hole. The movement of the base piece is reliably prevented. The narrow opening is formed in a part of the length direction of the through hole, and the entire through hole is not narrowed. Therefore, the brush body can be smoothly inserted into the through hole of the planting base piece. It becomes very easy to manufacture. In this way, the integration of the fiber bundle planting base piece and the rod-shaped brush body can be done without requiring complicated processes such as bonding and welding, so that the manufacturing process and manufacturing time can be reduced and the manufacturing cost can be reduced. it can. Furthermore, since the rod-shaped brush body is integrated by being inserted into the through hole of the fiber bundle planting base piece, even if a strong excessive force is applied, the fiber bundle planting base piece is not detached.
