Description

【０００１】
【発明の属する技術分野】
本発明は、塗料、絵の具、インキ、修正液、糊、化粧液、薬剤、補修剤、コーティング剤などの液状、粉状の塗布剤を塗布する弁機能を有した塗布具に関する。
【０００２】
【従来の技術】
内部に塗布剤収容室を設けた容器本体の開口部前方にたわみ変形可能な塗布先を取り付け、前記塗布剤収容室と塗布先との間に弁座部と、この弁座部に圧接するよう前方に付勢された弁部材とより構成した弁機構を配置してなる弁付塗布具としては、実公昭４２−１３６７１号公報に、上辺につば１ａを形成し中央に穿設した弁孔２に円錐弁座３ａと一体の弁棒３を突出させ、下部内設縁１ｂに係止した螺旋発条体４の上端部を前記弁座３ａの下面に固定３ａ´して弁座を弁孔２に圧接させた中蓋１を容器本体８の口部に挿着して、この上部から厚肉のスポンジラバー体７を受盤５ａに接着７´した外蓋５を前記弁棒３が受盤中央の弁孔６を貫通してスポンジラバー体内に挿入するよう冠着し、更にキャップ１０を冠合してなる塗布用液体容器を要旨とする考案が開示されている。
上記塗布剤用液体容器の使用法は以下の通りである。
スポンジラバー体を下にして被塗布面に押圧すると、スポンジラバー体の圧縮と共に弁棒が容器本体内方に移動し、弁座と弁孔との圧接が解除されて間隙が生じる。この間隙より容器本体内の内容液が流出してスポンジラバー体内に浸透する。この後、押圧力を解除して弁座と弁孔とを圧接密閉し、内容液を含浸したスポンジラバー体で所望の箇所に塗布する。
【０００３】
【発明が解決しようとする課題】
ところで、上記実公昭４２−１３６７１号公報に開示されるような塗布具は、手に持って塗布を行うことが多く、この場合、塗布具を被塗布面に対して垂直でなく、斜めに角度をつけて使用することが多い。これは、斜めに角度をつけて使用した方が、被塗布面への視界が良好となり、また、塗布先の被塗布面に対する接触荷重が小さくなるので、塗布しやすくなるためである。
一方、上記のような塗布具は塗布部を圧縮すると共に弁を開放する機構であるから、実用的な力で弁を開閉するために、弁棒の先端は少なくとも塗布先の中間部より前方に位置することが必要である。
このような塗布具においては、塗布時には、塗布先であるスポンジラバー体内の弁棒先端が固いので弁棒を押す感触が伝わり、ごつごつした感触になってしまい滑らかな感触を得ようとすることが困難であり、また、弁開放時には、弁棒を斜め後方に押圧することになり、弁棒が他の部材と接触しながら移動するため、弁棒に対する付勢力と接触抵抗荷重との和に抗して弁を開放することとなり、弁を開放する荷重が重くなるという問題があった。
【０００４】
本発明は、塗布時のごつごつした感触を低減し、かつ、弁を開放できる荷重が重くならず、しかも、小さな荷重でも確実に弁が開く弁付塗布具を提供することを課題とする。
【０００５】
【課題を解決するための手段】
本発明は、上記課題を達成するためになしたものであって、内部に塗布剤収容室を設けた容器本体の開口部前方に、たわみ変形可能な塗布先を取り付け、前記塗布剤収容室と塗布先との間に弁座部と、この弁座部に圧接するよう前方に付勢された弁部材とより構成した弁機構を配置してなる弁付塗布具において、前記弁部材が、その弁部の前方に、たわみ変形可能な凸片部を前記塗布先方向に突出させると共に、この凸片部先端に凸片部の厚さ寸法より大きい幅広部を設けたものであることを特徴とする弁付塗布具を要旨とする。
【０００６】
【実施例】
以下、本発明について添付図面を参照しながら、更に詳細に説明する。
第１実施例
図１〜図８に第１実施例を示す。図２は、図１の側面を示し、図３は図１の上面を示す。
図１の参照符号１は、先端が開口した容器本体である。この容器本体１の内部は横断面が偏平形の塗布剤収容室となっていて、容器本体１前方は略円筒状の開口部となっている。この開口部には、開口部先端の先端面１ａと、開口部内面の内周面１ｂと、開口部外周の螺旋形右締め方向の雄ねじ部を設けている。この雄ねじ部後端に続く後方には、塗布剤収容室の偏平形方向位置に前方が半円状の突起１ｃを２箇所設けている。
容器本体１前方には、貫通孔を有する全体が筒状の前軸２を螺合により取り付けている。
前軸２の貫通孔には、その先端から後方のやや離れた位置に水平に縮径する先段部２ａを設けており、この先段部２ａ後方に、縦断面が半円形で軸心方向に突出した全周状の内方リブ２ｂを、前後距離をおいて２本設けている。この内方リブ２ｂ後方に、円周上に配置した２箇所の前方半円形の軸心方向に突出する中突起部２ｃを設け、この中突起部２ｃ後端から水平に拡径する中段部２ｄを設け、そして中段部２ｄ上には後方に半円形に周状に突出する後方リブ２ｅを設け、更に、中段部２ｄから後端に向け、前記容器本体１の雄ねじ部と螺合する雌ねじ部を設けている。
前記後方リブ２ｅは、容器本体１と前軸２とを螺合したとき、容器本体１の開口部先端の先端面１ａと当接することによって、容器本体１と前軸２との結合を強固にするためのものである。
前軸２後端には、前方を半円形に切り欠いた切欠部２ｆが、円周上に２カ所形成されている。この切欠部２ｆは、上記容器本体１の前方が半円状の突起１ｃと嵌め合わされる。
前軸２外面には、先端から離れた途中位置に拡径する全周状の外方リブ２ｇを設け、この外方リブ２ｇ後方には、水平に拡径する外段部２ｈを設けている。
さらに、前軸２は上面から見て円形であるが、中突起部２ｃと切り欠き部２ｆとは、円中心方向からは、同一の方向に形成している。
【０００７】
容器本体１の開口部には、前方が扁平形であり、後方が円筒形であり、かつ前方及び後方が連通する塗布先３を取り付けている。この塗布先３は、容器本体１に取り付けられている前軸２の貫通孔を貫通して前方に突出している。
塗布先３は、たわみ変形が可能で横断面が略半円形の塗布片３ａが多数形成された塗布部３ｂと、塗布部後方に続く円筒部３ｃにより形成されている。
図４は塗布先３の塗布部３ｂ要部正面を示し、図５は図４の上面を示す。
塗布部３ｂは、後方から前方に先細り状にした塗布片３ａを、横方向に多数一列に並ぶようにし、この列を多数重合し、外側の列より内側の列の先端が突出するようにして形成したものであり、全体が偏平形の平筆穂状のものである。
塗布部３ｂ先端の正面中央部は、塗布片３ａの長さが、両側部の長さより短くなっており、凹部３ｄとなっている。
また、塗布部３ｂの左右には、塗布剤のはみ出しを抑制するための板状の脇板３ｅを設けている。
塗布先３内部には貫通孔が形成されている。この貫通孔には、塗布片３ａ後端から後方に向け横断面を方形に形成した開口部３ｆを設けており、この開口部３ｆ後方に筒状の中筒部３ｇを設け、中筒部３ｇ内面後端に弁座部３ｈを形成している。
塗布先３外部は、塗布片３ａ後端から後方に裾広がり状に拡径し、最大径箇所を鍔部３ｉとして設け、鍔部３ｉ後端から水平に縮径する外段部３ｊを設けている。この外段部３ｊは、前記前軸２の先段部２ａと当接する。
外段部３ｊから後方に、縦断面が半円形の拡径する全周状の先外方リブ３ｋを、前軸２内方リブ２ｂを乗り越える位置関係で２本設けている。
先外方リブ３ｋ後方には、前方半円形の軸心方向に凹んだ凹部３ｌを円周上に２箇所配置している。この凹部３ｌは、前軸２中突起部２ｃと嵌め合うように設けている。
凹部３ｌ後方には、縦断面が半円形の拡径する全周状の後外方リブ３ｍを、容器本体１内周面１ｂと密接するように、前後距離をおいて２本設けている。
塗布先３後端には、先方が半円形に切り欠かれた切欠部３ｎを、円周上に２箇所配置している。
切欠部３ｎから離れた内面先方に、全周に凹んだ周溝３ｏを設けている。凹部３ｌと切り欠き部３ｎの上面から見た配置関係は、円中心角度方向で９０度異なる方向に設け、又、開口部３ｆを上面から見て、長辺方向に凹部３ｌを、短辺方向に切り欠き部３ｎを設けている。
【０００８】
塗布先３の貫通孔内には、弁機能及び弾発性機能を有する弁部材４を配している。
弁部材４先端には、たわみ変形可能な凸片部４ａを設けている。この凸片部４ａは、横断面が方形の板状のものであり、前記塗布先３開口部３ｆを通過して、塗布部３ｂ内に突出している。
凸片部４ａには、前方の側面に左右２箇所、後方が広がるように突出する凸部４ｂを設けている。凸部４ｂ後方には周囲に段状に広がる段部４ｃを設けている。
凸片部４ａ後端に球面状の弁部４ｄを連設している。この弁部４ｄは、塗布先３の弁座部３ｈと円周線で当接するように設けている。弁部４ｄと連設して後方に螺旋形の２本の弾撥部４ｅを、塗布先３円筒部３ｃ内面と接触しないように設けている。弾撥部４ｅ後端に円筒状の後筒部４ｆを設け、後筒部４ｆ外壁の先方には拡径する全周状の外方リブ４ｇを塗布先３周溝３ｏに嵌め合わせるように設けている。後筒部４ｆ後端には、前方が半円状の突起４ｈを円周上に２カ所設けている。この突起４ｈは、塗布先３切欠部３ｎと嵌め合わされるものであり、弁部材４を上面から見て、凸片部４ａの長辺側中央方向に配置している。
弁部材４は外方リブ４ｇで塗布先３と固定され、弾撥部４ｅにより弾撥され、弁部４ｄが塗布先３弁座部３ｈと圧接することにより弁機構を形成している。又、弁部材４凸片部４ａの横断面積（幅×厚さ）は、塗布先３の各塗布片３ａ横断面積より大きくし、たわみ度あいが凸片部４ａより塗布片３ａの方が大きくなるようにしている。
弁部材４凸片部４ａ先端には、幅広部を形成している。実施例１において、幅広部は、凸片部４ａ先端に固着した、後方が開口した側面から見て傘形状の先体５によって形成している。
本実施例において、幅広部を弁部材４と別体の先体５によって形成したのは、本弁付塗布具を組み立てる都合上である。即ち、弁部材４の凸片部４ａを、塗布先３の開口部３ｆを通して、塗布部３ｂに挿入するとき、凸片部４ａの先端に幅広部が形成されていたのでは、凸片部４ａが開口部３ｆを通らないためである。つまり、凸片部４ａを開口部３ｆに通した後、先端に、先体５を取り付けることによって、凸片部４ａ先端に幅広部を形成するわけである。従って、幅広部は、凸片部４ａと別体のものによって形成されるべき必然性はなく、後述する実施例２に記載したように凸片部４ａと一体の構造によって形成することも可能である。
図６は先体５の正面の部分断面を示し、図７はその側面の全断面を示す。
先体５は、板状部５ａと、この板状部５ａの上側に設けた鍔部５ｂとよりなっている。前記板状部５ａには、後方が開口した空間部が形成されおり、更に、両方の短辺側壁に透窓５ｃが形成されている。先体５は、板状部５ａの空間部に凸片部４ａの先端を挿入して固着されるが、この時、先体５後端は、弁部材４段部４ｃと当接し、透窓５ｃは、弁部材４凸部４ｂが嵌め込まれる。
先体５先端は塗布先３先端より僅かに先方に突出するように配置されている。
本発明に係る弁付塗布具において、先体５の鍔部５ｂは、弁部材４凸片部４ａの厚さ寸法より大きく形成され、幅広部となっている。
鍔部５ｂの背面と、その後方の塗布先３塗布片３ａ先端との間には空隙部５ｄが存在する。この空隙部５は、本発明に係る弁付塗布具を使用するとき、弁部材４が塗布片３ａに影響されずに後退できるように設けたものである。従って、空隙部５ｄは、塗布片３ａの形状、材質などを適宜設計、選択することによって、その有無、形状、大きさを選択することができる。本実施例における空隙部５ｄの寸法を寸法Ｐで示す。
先体５先端面中央には、凹条に窪んだ凹部５ｅを設けている。
また、先体５全体は、塗布先３ａ凹部３ｄに収まるように設けている。
先体５の組み立て順序は、塗布先３ａ後方から弁部材４を挿入組み立てし、弁部材４弁部４ｄの背面を組み立て治具で受け、弁部材４の後方移動を阻止した後、先体５を先方から弁部材４凸片部４ａ先端に挿入組み立てする。
参照符号６は、略円筒状、有底状の後方が開口したキャップである。このキャップ６は、塗布先３を外側から保護し、前軸２と脱着しうる様になっている。
キャップ６内面の前後略途中位置に、全周状に軸心方向に縮径し、前軸２先端外周面と密接するように、内方リブ６ａを設けている。そして、内方リブ６ａ後方に、軸心方向に突出する係止リブ６ｂを円周上で４ヶ所設けている。この係止リブ６ａは、キャップ６を前軸２に取り付けたとき、前軸２外方リブ２ｇを乗り越える位置に形成する。
キャップ６の後端面は、キャップ６を前軸２に取り付けたとき前軸２外段部２ｈと当接する。
【０００９】
本発明の作用効果について図８を参照して説明する。
参照符号７は、紙面等の被塗布面である。塗布部位で実線の細線は被塗布面に押し当てる前の状態を示し、実線の太線は被塗布面に押し当てた後の塗布部位が変形し開弁した状態を示す（塗布部位の変形垂直長さを＜寸法Ｑ＞で示す）。塗布時、塗布先の塗布部を被塗布面に押し当てると、塗布部の塗布片がたわみ変形可能となっているので湾曲変形する。このとき、塗布片からなる列の間に設けた弁部材の凸片部もたわみ変形可能となっているので湾曲変形する。以上のように、凸片部は、塗布片の変形に従って湾曲変形するので、塗布操作でのごつごつした感触が低減する。
更にこの時、塗布先先端より僅かに突出した、幅広部を有した先体は、被塗布面に接触する塗布部位の中で最も接触抵抗が大きくなり、先体にかかる応力も相対的に大きなものとなる。この時、先体と一体に連結された弁部材は、その弾撥力に抗して弁部が塗布先弁座部から容器後方に離れ、弁が開口する。（開口における寸法をＲで示す。）
弁が開口すると、塗布液収容室内の塗布剤は、弁を通過し、塗布先塗布部の各塗布片内に分散されて被塗布面へと流出する。
弁開口時における先体の後方移動に対する塗布先の影響は以下の通りである。先体幅広部の背面（先体先端面の裏面）塗布先塗布片先端との間には空隙部を設けているので、先体が塗布先に干渉することなく、円滑に後方移動することが出来る。更に、被塗布面の反対面でも、先体幅広部の背面と塗布先端列の塗布片先端との間に空隙部を設けているので、塗布部位が湾曲変形しても、先体は塗布先に干渉することなく円滑に後方移動することが出来る。
又、被塗布面側で、塗布先端列の中央側の塗布片を短くしているので、図に示す如く、この塗布片の曲り程度が同列の他の長い塗布片曲りより少ない程度なので、結果として、塗布片間の開き方で塗布先端列の中央側が左右両側より多く開くこととなる。（中央側の塗布片と、左右両側の塗布片との開きの差を寸法Ｓで示す。）
このことによって、塗布剤の被塗布面側への流出量を中央側に多く、端側に少なくすること、つまり、偏平塗布先両側への塗布剤はみ出し量を抑えることが出来る。そして、同様の作用によって、弁から塗布部中央先端迄の塗布剤流出時間を短く、つまり、塗布剤吐出即答性を高めることが出来る。
尚、先体後方移動と塗布先先端との干渉阻害は、塗布片後方曲げ強度が高い場合に生ずるものであり、塗布片材質が軟質で、又は、繊細な形状等で、塗布片後方曲げ強度を低くすれば、塗布先先端が先体幅広部の背面と接触しながら他方向に変形（＝逃げる）するので、先体幅広部背面の空隙部を設けなくても良い。
塗布時、塗布剤は各塗布片へと分散されて被塗布面へと塗布されるが、先体先端中央に設けた凹部に多めに塗布剤が導かれるので、被塗布面への先体接触域と他の塗布片接触域とは同等の塗布量状態となるものである。
【００１０】
第２実施例
図９〜図１２に第２実施例を示す。
第２実施例は、第１実施例において、弁部材を、下記に示すものを用いた以外は第１実施例と同様である。従って、第２実施例の説明は、弁部材１４についてのみ行う。
図９は弁部材１４の前方要部を示し、図１０は弁部材１４を一部曲げ加工し、幅広部を形成した後の状態を示す。図１１は図１０の側面を示し、図１２は図１０の上面を示す。
弁部材１４は、前方に板状の凸片部１４ａを設け、この凸片部１４ａ後方に部分球形状の弁部１４ｄを、更に、その後方には２条の螺旋形の弾撥部１４ｅを設けたものである。
凸片部１４ａは、その先端中央にスリット状の切り欠き部１４ｉを設け、その後方には、凸片部１４ａ後端迄直線状に突出するリブ１４ｊを設けている。
塗布先（不図示）に弁部材１４を組み立てた後、切欠部１４ｉの後方の折り曲げ部１４ｋ位置で側面から見て、傘状に折り曲げることによって、凸片部１４ａ先端に鍔部１４ｌを形成する。この時、折り曲げた後の切欠部１４ｉ後端は正面から見て窪んだ凹部１４ｍとなしている。
本発明に係る弁付塗布具において、上記鍔部１４ｌは、凸片部１４ａの厚さ寸法より大きく形成され、幅広部となっている。
尚、切欠部１４ｉは凸片部１４ａ横断面の長辺側に設けたが、短辺側に設けても、さらに１ヶ所ではなく複数設けても良い。幅広部１４ｌを形成する折り曲げ角度、折り曲げ方向も必要に応じた設定で良い。弁部材のリブも面上に１本で示したが、必要に応じて複数本設けても良い。
【００１１】
本実施例の作用効果は第１実施例と略同様であるが、更に付け加えると以下のようである。
幅広部は、弁部材と同体に設けることが出来、先体等の部材を別に設けなくても良い。又、凸片部の略全長にリブを設けているので、弁開閉作動時の凸片部と塗布先開口部接触が線接触から点接触になり、より接触抵抗を低減出来、弁開閉作動を円滑に出来るものである。
【００１２】
第３実施例
図１３〜図１５に第３実施例を示す。
第３実施例は、第１実施例において、弁部材を、下記に示すものを用いた以外は第１実施例と同様である。従って、第３実施例の説明は、弁部材２４についてのみ行う。
図１３は先端一部断面の弁部材２４の先方要部を示す。図１４は図１３の側面を示し、図１５は図１３の上面を示す。
弁部材２４は、前方に板状の凸片部２４ａを設け、この凸片部２４ａ後方に部分球形状の弁部２４ｄを、更に、その後方には２条の螺旋形の弾撥部２４ｅを設けたものである。前記、凸片部２４ａ先端中央に球形状の球部２４ｎを設け、この球部２４ｎ後端には凸片部２４ａ肉厚より薄い凹条２４ｏを設けている。
そして、凸片部２４ａ先端には、先端が膨らんだ略円盤形の先体２５を固着している。
先体２５は、円盤形の直径を幅広部２５ｂとなし、内部に球形状の凹球部２５ｅを設け、先方に開口する開口部２５ｆを設けている。
内部に設けた凹球部２５ｅは、前記弁部材２４球部２４ｎを外側から嵌め込む為に設けたものである。
尚、先体と弁部材の結合関係は、先体側に球部を設け弁部材側に凹球部を設けても良く、さらに、球形状の回転構造ではなく、円柱形状の回転軸構造を採用しても良い。
【００１３】
本実施例の作用効果は第１実施例と略同様であるが、更に付け加えると以下のようである。先体と弁部材球部は球状に球心を中心として先体全体が回転するように嵌め込まれていて、かつ、弁部材に屈曲変形部となる凹条を有しているので、塗布操作で被塗布面に先体を接触させた時、先体がその接触状態に応じた当接角度となり、その接触状態はより一定となるので、弁部材の開閉作動性はより安定したものとなる。
【００１４】
第４実施例
図１６〜図１８に第４実施例を示す。
第４実施例は、第１実施例において、弁部材を、下記に示すものを用いた以外は第１実施例と同様である。従って、第４実施例の説明は、弁部材３４についてのみ行う。
図１６は弁部材３４の先方要部を示す。図１７は図１６の側面を示し、図１８は図１６の上面を示す。
弁部材３４は、前方に板状の凸片部３４ａを設け、その凸片部３４ａ後方に部分球形状の弁部３４ｄを、更に、その後方には２条の螺旋形の弾撥部３４ｅを設けたものである。
凸片部３４ａ先端中央には、側面から見て傘形状の幅広部３４ｌを設けている。この幅広部３４ｌ表面には、幅広部３４ｌ正面中央から上面に繋がる窪んだ溝状の凹部３４ｍを設けている。
凸片部３４ａ先端の幅広部３４ｌ後方には、方形に開口した透孔３４ｐを設けている。
塗布先（不図示）と弁部材３４との組立ては、上記弁部材３４の幅広部３４ｌを透孔３４ｐ側へ折り曲げて、塗布先後方から塗布先の横断面方形形状の開口部を通過させた後、弁部材３４の幅広部３４ｌを元の形状に戻す方法を採用する。
尚、透孔３４ｐ形状は方形で示したが、台形形状・楕円形状・波枠取り形状等必要に応じて種々の形状を採用出来、又、１ヶ所ではなく複数設けても良い。さらに凸片部３４ａの透孔３４ｐ以外の幅広部３４ｌへの橋渡し箇所に、組立時折り曲げ性を良くするため溝形状を設けたり、補強のため縦リブを局部配置しても良い。
【００１５】
本実施例の作用効果は第１実施例と略同様であるが、更に付け加えると以下のようである。幅広部は第２実施例と同様に、弁部材と同体に設けることが出来、かつ、幅広部を左右対称に設けられるので、第１実施例と同様に弁開き作動性を良く出来るものである。
【００１６】
【発明の効果】
本発明の弁付塗布具は、塗布時のごつごつした感触を低減し、かつ、弁を開放できる荷重が重くならず、しかも、小さな荷重でも確実に弁が開き、円滑に塗布剤が吐出するといった長所を有するものである。

BACKGROUND OF THE INVENTION
The present invention relates to an applicator having a valve function for applying a liquid or powdery coating agent such as paint, paint, ink, correction liquid, glue, cosmetic liquid, medicine, repair agent, coating agent or the like.
[0002]
[Prior art]
An application destination that can be flexibly deformed is attached to the front of the opening of the container main body provided with an application agent storage chamber, and a valve seat portion and the valve seat portion are pressed against each other between the application agent storage chamber and the application destination. As a valve applicator formed by arranging a valve mechanism constituted by a valve member biased forward, a valve hole 2 formed in Japanese Utility Model Publication No. 42-13671 is formed with a collar 1a on the upper side and drilled in the center. The valve stem 3 integral with the conical valve seat 3a is protruded to the upper end of the spiral ridge 4 which is locked to the lower inner edge 1b, and the valve seat 3 is fixed to the lower surface of the valve seat 3a. The valve lid 3 receives the outer lid 5 in which the inner lid 1 is pressed into the mouth of the container body 8 and the thick sponge rubber body 7 is bonded to the receptacle 5a from the upper portion 7 '. A liquid container for coating formed by being pierced so as to pass through the central valve hole 6 and inserted into the sponge rubber body, and further cap 10 The idea which makes a summary is disclosed.
The usage method of the liquid container for coating agent is as follows.
When the sponge rubber body is pressed down and pressed against the surface to be coated, the valve rod moves inward of the container body as the sponge rubber body is compressed, and the pressure contact between the valve seat and the valve hole is released to create a gap. The liquid in the container body flows out from the gap and penetrates into the sponge rubber body. Thereafter, the pressing force is released, the valve seat and the valve hole are pressed and sealed, and the sponge rubber body impregnated with the content liquid is applied to a desired location.

By the way, an applicator as disclosed in the Japanese Utility Model Publication No. 42-13671 is often held by hand, and in this case, the applicator is not perpendicular to the surface to be applied but is inclined at an angle. It is often used with This is because, when the device is used at an oblique angle, the field of view to the coated surface becomes better, and the contact load on the coated surface at the coating destination becomes smaller, which makes it easier to apply.
On the other hand, the applicator as described above is a mechanism that compresses the applicator and opens the valve. Therefore, in order to open and close the valve with a practical force, the tip of the valve stem is at least forward of the middle part of the application destination. It is necessary to be located.
In such an applicator, at the time of application, the tip of the valve rod in the sponge rubber body, which is the application destination, is hard, so that the feel of pushing the valve stem is transmitted, and it becomes a terrible feel and tries to obtain a smooth feel. It is difficult, and when the valve is opened, the valve stem is pushed diagonally backward, and the valve stem moves while contacting other members, so it resists the sum of the urging force against the valve stem and the contact resistance load. As a result, the valve is opened, and the load for opening the valve becomes heavy.
[0004]
An object of the present invention is to provide a valve-equipped applicator that reduces the harsh feel at the time of application and does not increase the load that can open the valve, and that reliably opens the valve even with a small load.
[0005]

[0009]
The effect of this invention is demonstrated with reference to FIG.
Reference numeral 7 denotes a surface to be coated such as a paper surface. The solid thin line at the application site shows the state before being pressed against the surface to be applied, and the thick solid line shows the state where the application site after being pressed against the application surface is deformed and opened (the deformation vertical length of the application site) (Indicated by <dimension Q>). At the time of application, if the application part at the application destination is pressed against the surface to be applied, the application piece of the application part can be bent and deformed, so that it is curved and deformed. At this time, the convex piece portion of the valve member provided between the rows of the application pieces can be bent and deformed, so that it deforms in a curved manner. As described above, the convex piece portion is curved and deformed in accordance with the deformation of the application piece, so that a rough feel in the application operation is reduced.
Furthermore, at this time, the tip body having a wide part slightly protruding from the tip of the coating tip has the highest contact resistance among the coating portions contacting the surface to be coated, and the stress applied to the tip body is relatively large. It will be a thing. At this time, the valve member integrally connected to the tip body is separated from the coating destination valve seat portion toward the rear of the container against the resilience, and the valve opens. (The dimension at the opening is indicated by R.)
When the valve opens, the coating agent in the coating liquid storage chamber passes through the valve, is dispersed in each coating piece of the coating destination coating unit, and flows out to the coated surface.
The influence of the application destination on the backward movement of the tip body when the valve is open is as follows. Since the gap is provided between the back of the wide part of the front body (the back of the front end surface of the front body) and the tip of the application destination application piece, the front body can smoothly move backward without interfering with the application destination. I can do it. In addition, even on the opposite side of the surface to be coated, a gap is provided between the back surface of the wide part of the tip body and the tip of the coating piece in the coating tip row, so that the tip can be applied to the coating tip even if the coating site is curved and deformed. It is possible to move backward smoothly without interfering with.
Also, since the coating piece on the center side of the coating tip row is shortened on the coated surface side, as shown in the figure, the degree of bending of this coating piece is less than the other long coating piece bending of the same row, so the result As a result, the center side of the coating tip row opens more than the left and right sides in the way of opening between the coating pieces. (The difference in opening between the central application piece and the left and right application pieces is indicated by a dimension S.)
As a result, the amount of the coating agent flowing out to the coated surface side can be increased toward the center side and decreased toward the end side, that is, the amount of the coating agent protruding to both sides of the flat coating destination can be suppressed. And by the same effect | action, the coating agent outflow time from a valve to the application | coating part center front-end | tip can be shortened, ie, coating agent discharge quick response property can be improved.
In addition, interference inhibition between the forward movement of the tip and the tip of the coating tip occurs when the coating piece rear bending strength is high, and the coating piece material is soft or has a delicate shape, etc. Since the tip of the coating tip deforms in the other direction (= escapes) while contacting the back surface of the wide front body portion, the gap portion on the back surface of the wide front body portion need not be provided.
At the time of application, the coating agent is dispersed into each coating piece and applied to the surface to be coated. However, since the coating agent is guided more to the recess provided in the center of the tip of the body, the tip contacts the surface to be coated. The area and the other application piece contact area are in the same application amount state.
