《発明の属する技術分野》
本発明は朱肉皿に関する。
【0002】
《従来の技術》
【0003】
従来、朱肉皿は、綿やスポンジなどの吸蔵体の毛細管作用を利用し朱肉インキを吸収させ、調節体やクッション体に表布を配設した構造をもっている。
【0004】
そのため、捺印する際その印面に印鑑の刻面を押し付け、吸蔵体を圧迫し、吸蔵体の朱肉インキを印面に染み出させ、印鑑の刻面に、適度に朱肉インキを付着させ捺印する。そして一定の圧力で表布にインキのしみ出す量はその吸蔵体が含むインキの量に比例する。
【0005】
したがって印鑑の刻面に一定の朱肉インキを付着させ良好な捺印を得ようとすれば、吸蔵体に含まれる朱肉インキの量の変化にあわせて印面に刻面を圧しつける圧力も変化させなくてはならない。つまり吸蔵体の朱肉インキの含有量が多いときには刻面を軽く圧しつけ、朱肉インキを使用し吸蔵体の含有量が少なくなるにしたがい、刻面を強く圧しつけなくてはならない。
【0006】
それは、印鑑本体を手に持ち卓上型の朱肉皿を使用した場合や、キャップ内部の可動式の朱肉皿を使用時にキャップ底のボタンを押し、朱肉皿の印面を刻面に圧しつけるタイプの印鑑ケース(例えば、実第2542307号、特開平11−34463、特開2000−229466等)では可能ではあるが、吸蔵体の朱肉インキの含有量の減少に応じて刻面を圧しつける圧力を調節しなくては良好な捺印を得られず、確実に良好な捺印を得ようとすれば朱肉インキの付着量を確認する必要もある。
【0007】
また、キャップ内部に固定式の朱肉皿をもつ筒状の印鑑ケース(例えば実昭56−19532、実昭62−102662等)やキャップ底部と可動式の朱肉皿の間にバネを設けた筒状の印鑑ケース(例えば実第3004178号、特開平11−129498等)では圧力の調整はできない。
【0008】
たとえ筒状の印鑑ケース本体にネジ式等の印鑑本体を押し出す機構をもたしたとしても、固定式の朱肉皿をもつ印鑑ケースの場合には圧力の調整は可能ではあるものの、吸蔵体の朱肉インキの減少に応じて調節するのは煩わしく、朱肉皿の下にバネをもつ印鑑ケースの場合には、朱肉皿が押し下げられるだけなので大きな効果は得られない。
【0009】
そして、一般の朱肉皿のように綿やスポンジ等の吸蔵体に朱肉インキを含ませ、その吸蔵体に圧力を加えることにより、朱肉インキを印面に供給する方法では、吸蔵体に一定以上のインキを含ませると少し圧力を加えただけでインキが表部に過剰にしみ出し、捺印が不鮮明になるため、その吸蔵体が毛細管作用により含有できるインキの量を下まわる量しか含ませることができず、しかも実願20200080286の印鑑ケースの場合、捺印するとき以外は常に印面に圧力がかかるため、長期間使用する間に徐々に吸蔵体が圧縮縮小し頻繁に使用しなければ含有する朱肉インキを印面にしみださせ捺印が不鮮明になる恐れがあり、さらに朱肉インキの含有量を少なくする必要があると考える。したがって朱肉皿の体積が大きな卓上型の朱肉皿では問題はないが、印鑑ケースに内蔵する体積の小さな朱肉皿では実務に使用した場合に不便と感じないほどの捺印回数を得ることが難しいと考える。
【0010】
しかも吸蔵体の朱肉インキが減り、圧力を加えても印面に十分に供給できなくなっても吸蔵体内には朱肉インキが残り、効率的に使用することができない。
故に、ある程度捺印し続けても印面に安定して朱肉インキを供給し、捺印可能回数を増やすためには、吸蔵体が圧力を受けない構造をもち朱肉インキを飽和状態に含んだ吸蔵体をもつ朱肉皿、もしくは朱肉インキのタンクを備えた朱肉皿が有効と考えられ、朱肉タンクをもつ朱肉皿は考案もされている(実開平6−42200)
【0011】
しかし、この考案と似た試作品と、朱肉タンク内に密度の低いスポンジを設置し、通液穴を大きくしてフェルトを挿入し、朱肉インキをクッション体に供給する試作品を作成し、実願20200080286の印鑑ケースで実験したところ、下記のような問題が明らかとなった。
【0012】
この朱肉カートリッジは印鑑を挿入していない状態で印鑑ケースに内蔵し、また交換用に単体で販売されることが想定され、最低数週間から数年間保管されると予想される、つまり製造されてから使用されるまで、長期間印面に圧力がかかっておらず、圧力のかかっていない液伝体やクッション体は体積が大きく密度が低いため、その材料がもつ毛細管作用の限度いっぱいまで朱肉インキで飽和状態の吸蔵体や、朱肉タンクから供給される朱肉インキを吸収してしまうと、圧縮された際、含んでいた朱肉インキが圧し出され、この印鑑ケースに使用される印面の小さな朱肉皿では朱肉インキが周囲に逃げることができないので表布にしみだし、捺印が不明瞭となる。
【0013】
そしていったん使用されれば、キャップを閉めた状態、つまり印面に圧力がかかった状態で数カ月から数年間保管される。そして朱肉インキを飽和状態に含んだ吸蔵体、又は朱肉タンクをもち圧縮されないでも朱肉インキを供給することを特徴とする朱肉皿は、一般の吸蔵体をもつ朱肉皿とは異なり、朱肉インキで飽和状態の密度の低いスポンジや朱肉タンク内の朱肉インキは、毛細管作用など朱肉インキを留まらせるための力が低く、適度な毛細管作用をもつ液伝体を使用しても、時間が経過すると、表布にに朱肉インキがしみだし捺印が不明瞭となる。
【0014】
また、長期間使用された印鑑の周囲は擦り減っていることが多く、印面の大きな卓上型の朱肉皿を使用すれば、印面に印鑑を押し付けた際、印鑑を圧しつけた周囲の印面が回りの印面に引っ張られ、沈み込むような形となり擦り減った印鑑の周囲にも朱肉インキを付着させるが、筒状の印鑑ケースに内蔵する印鑑の直径に近い大きさの印面をもつ朱肉皿では印鑑を押し付けた周囲の印面が回りの印面に引っ張られることがなく、しかも筒状の印鑑ケースに内蔵した場合、卓上の朱肉皿を使用する際のように印面に印鑑の刻面を圧しつける角度を変化させる事ができないため、擦り減った印鑑の周囲に朱肉インキが付着しにくい傾向がある。
【0015】
そのことに対処するため厚く柔らかいクッション体を使用すると、圧迫された際クッション体が含んでいるインキが大量に朱肉面に放出され捺印が不鮮明になる問題が生じる。
【0016】
そして、朱肉タンクを内蔵する朱肉皿の場合、タンク内の朱肉インキが減少するのに伴い、タンク内に空気が入り込み、携帯して移動する際に山を越える、寒い事務室に置いていた印鑑ケースを暖かいポケットに入れるなど、外気圧よりタンク内の気圧が高くなった際、膨張した朱肉タンク内の空気が朱肉インキを印面に圧しだし、印面にたいするインクの供給が過剰となり、捺印が不鮮明となる事が確認され、とくに二千メートルの高度に相当するほど気圧の下がる旅客機内では漏れた朱肉インキが印鑑ケースから出て、ポケットを汚染する事態が発生した。
【0017】
そのことに対応するため、朱肉皿下部に表面張力の作用を利用した留液室をもたせるなど、さまざまな試作品を作成し実験したが、旅客機内の気圧低下に対応する程に留液室を大きくすればサイズの限られた朱肉皿では朱肉タンクの容量が小さくなり、捺印可能回数が減り、また留液室に流れ込んだ粘度の高い朱肉インキは気圧がもとに戻っても、ある程度の量が留液室に残留するため、エレベーターに毎日乗るなど、気圧の変化が繰り返されれば、留液室が朱肉インキで満たされ、外部に漏れる恐れがある、などの問題を解決することができなかった。
【0018】
《発明が解決しようとする課題》
印鑑ケースに内蔵できるほど小型で、同体積の一般の構造をもつ朱肉皿に比べて捺印可能回数を増やし、朱肉皿が保有する朱肉インキの残量にかかわらず一定の圧力で良好な捺印を可能とするために朱肉タンクを内蔵した場合に発生する下記の問題を解決する。
朱肉皿の印面に圧力が加わらない状態で長期間保管しても朱肉タンクより朱肉インキがクッション体に伝わらないようにする。
朱肉皿の印面に圧力が加わった状態で長期間保管しても良好な捺印を可能とする。印面が印鑑の刻面の直径に近い朱肉皿でも、ある程度刻面の周囲が擦り減った印鑑の刻面の周囲に朱肉インキを付着させる。
朱肉タンクを内蔵した朱肉皿を、一般の生活環境下で朱肉タンク内の空気が膨張しても朱肉インキの供給量の変化をきたさない。
【0019】
《課題を解決するための手段》
本発明者は本発明に関係する考案を申請している(実願2001007885)(実願20200080286)(特申者整理番号KK03、KK05)
そしてこの朱肉カートリッジは実願20200080286の印鑑ケース用に研究開発されている。
【0020】
本発明の朱肉皿(図1)は、印面を保護し朱肉カートリッジを印鑑ケースキャップ内に押し込んだ際、指先が汚れないようにするシール(1)、表布(2)、起毛体(3)、上貯液体(4)、下貯液体(5)、弁シール(6)、朱肉インキ(22)、朱肉インキ(22)に含ませる流動性低下材(7)、過流動防止シール(8)、パッキン(9)、朱肉タンク(10)を形成するための隔壁(11)をもつ朱肉皿主部(12)、そして朱肉皿支持体(13)から構成される。
【0021】
朱肉皿主部(12)の隔壁(11)の上部に下貯液体(5)を設置する。下貯液体(5)は朱肉インキを吸収しやすい布などで作られ、中央に穴をもつ。その上にシリコンゴムの薄膜などの非通液性の弁シール(6)を下部中央に接着した上貯液体(4)を設置しする。下貯液体(5)と上貯液体(4)は密に織られた布など朱肉インキを含むと通気性がなくなる材料を使用する。
【0022】
その上に起毛体(3)を設置する。起毛体(3)下部中央と上貯液体(4)中央は接着剤で接続される。起毛体はナイロンなどインキが浸透しにくく弾力性をもつ化学繊維で織られ、起毛体の上面(20)と起毛体の下面(21)に網の目(14)の平面を構成し、上面と下面の間の繊維(15)が毛細管作用が発生しない距離をおいて平面に体して縦方向に並び、圧迫されない状態では繊維(15)どうしが接触しない、もしくは中間部以上で接触する生地を使用する。ナイロンなどの化学繊維で織られた生地は復元力を失いにくく、現在実験中の試作品に使用している起毛体は、圧迫され続けると、ある程度繊維が寝てしまうがそれ以上は変形せず起毛体としての機能を失わないため実願20200080286の印鑑ケースのように常にクッション体を圧迫する印鑑ケースに内蔵する朱肉皿にも使用できると考える。(起毛体を有する朱肉皿に関して本発明者は特許を申請している整理番号KK05)
【0023】
そして起毛体(3)上部に起毛体の網の目(14)が印鑑の刻面に朱肉インキが均等に付着することに影響を与えない厚さをもつ表布(2)を設置する。
【0024】
以上のように構成すると圧力が加わらない状態では朱肉タンク(10)内の朱肉インキ(22)は隔壁(11)の通液穴(16)上部の開口部(17)まで毛細管作用により達する。開口部(17)まで達した朱肉インキは表面張力により開口部(17)で止まり、開口部(17)は下貯液体(5)や弁シール(6)、上貯液体(4)に接していないため、朱肉カートリッジを長期間保存しても朱肉インキが下貯液体(5)や上貯液体(4)に伝わらず表布(2)に過剰に朱肉インキが供給され捺印が不明瞭になることはなく、生産、出荷時に弁シール(6)以上の構造物を上方に引き上け通液穴(16)の開口部(17)との距離をあければ、その機能はより確実となる、(図12)
【0025】
そして使用時、表布(2)に印鑑の刻面により圧力が加わり、起毛体(3)が圧縮されると同時に弁シール(6)が押し下げられ、弁シール(6)は通液穴の開口部(17)を塞ぎ朱肉インキの供給を遮断するため、キャップを閉めた状態、つまり印鑑の刻面により表布(2)に圧力がかかった状態で長期間保存されても表布(2)に朱肉インキがしみ出し捺印が不明瞭になることはない。(図13)
【0026】
キャップを外し表布(2)に圧力がかからなくなった状態では弾力性のあるナイロンなどの化学繊維で織られた起毛体(3)は復元力が強く元の状態に戻るため、上貯液体(4)を挟んで起毛体の下面(21)に繋がった弁シール(6)は引き上げられ通液穴(16)の開口部(17)より離れる。しかし開口部(17)と弁シール(6)の離れる距離が短く、下貯液体(5)に通気性がないため粘度の高い朱肉インキは弁シール(6)より離れず、開口部(17)より引き出された朱肉インキ(22)は朱肉皿主部(12)と弁シール(6)との間を伝わり下貯液体(5)に達し、弁シール(6)が薄いため下貯液体(5)と上貯液体(4)の周囲は離れず、下貯液体(5)と上貯液体(4)は弁シール(6)の周囲より朱肉インキを吸収し、起毛体の下面(21)は毛細管作用の飽和状態になるまで朱肉インキを吸収する。また上貯液体(4)と下貯液体(5)は通気性がないため隔壁(11)と弁シール(6)の間に空気が入らず、朱肉インキが含む流動性低下材(7)に毛細管作用が発生しても、流動性低下材(7)の毛細管作用による吸引力が貯液体の吸引力を越え通液穴(16)に空気が侵入するまで貯液体は朱肉インキ(22)を吸収し続ける。(図14)
弁シールを起毛体の下部に直接接着してもこの機能を得ることはできるがより確実に空気の侵入を防ぐために上貯液体を設置するのが望ましいと考える。
【0027】
下貯液体(5)と上貯液体(4)、起毛体の下面(21)が毛細管作用の飽和状態となっても圧迫されていない起毛体(3)の内部の繊維は毛細管作用が発生しない距離をおいて平面にたいして縦方向に配列しているため朱肉インキを吸収することはなく、朱肉インキは起毛体の上面(20)や表布(2)に供給されることはない。
【0028】
しかしその状態で朱肉カートリッジを横にし、長時間放置すれば上貯液体(4)や起毛体の下面(21)の周囲と朱肉皿主部(12)の内壁が接触しているため徐々に朱肉インキがしみだし朱肉皿主部(12)の内壁を伝わり表布(2)に達するが、試作品の実験では二日程では朱肉インキの漏れは捺印に影響を与えない程度のため、業務で卓上型の朱肉皿と併用し、一日キャップを閉めない状態が発生しても終業時にキャップを閉めるようにすればよいので実用上大きな問題はないと考える。また起毛体や貯液体をヒートカットで打ち抜き、それらの周囲の繊維を溶解させ周囲のみ毛細管作用が発生しないようにすれば、より朱肉インキの漏れを抑えることができると考える。
【0029】
そして表布(2)に圧力が加わり、起毛体(3)が圧迫されると起毛体(3)の内部の繊維(15)が圧され、寝た状態となり繊維どうしが接触し毛細管作用が発生し、起毛体の上面(20)と表布(2)に起毛体(3)下部に含まれた朱肉インキが供給される。起毛体(3)は圧迫された際の体積の変化が大きくクッション性に優れているが内部に朱肉インキを含むことがないので圧迫された際に押し出される朱肉インキは下貯液体(5)と上貯液体(4)、起毛体の下面(21)が含む朱肉インキのみでその量は少なく、起毛体(3)の上下面の網の目(14)の空間に逃れ、表布(2)にしみだし捺印が不明瞭となることはない。
【0030】
また起毛体(3)は体積が大きくなっても朱肉インキを含まないため、一般の朱肉皿のクッション体のように圧縮された際に放出する朱肉インキを考慮する必要がなく、表布の上下の移動の行程を大きくする事ができ、表布の周囲と朱肉皿主部の内壁との摩擦を利用して擦り減った刻面の周囲(24)に朱肉インキを付着させる機能を発生させることができる。
(この機能に関して本発明者は特許を申請している整理番号KK03)
また既に申請しているKK03の朱肉カートリッシの台バネとして起毛体を使用した場合は上面に固定した閉塞体を下方に貫通させれば隔離板も必要とせず材料費も低いため大幅なコストダウンが期待できる。
【0031】
そして、朱肉タンクをもたせた場合に発生する気圧の変化に対処するには下記の方法を用いる。
【0032】
朱肉タンク(10)に粘度の高い朱肉インキを空気を含まないように入れる。粘度の高い朱肉インキは通液穴(16)を通り開口部(17)まで達し、表面張力の作用により漏れることはない。その朱肉インキに、定形をもたせず毛細管現象が発生しない程度の少量の超極細繊維や脱脂綿などの弾力性が弱い繊維の流動性低下材(7)を入れ、拡散させる。 (試作品の場合、6ミリの高さの朱肉タンクに使用する脱脂綿は圧縮すると0.1ミリ程になり、流動性低下材を含まない朱肉インキと含んだ朱肉インキの体積の変化は肉眼では確認できない)
【0033】
粘度の高い朱肉インキの中に、流動性低下材(7)を含んだ粘度の高い朱肉インキはその繊維の周囲に粘着し、流動性が低くなり、泥のような状態となるため、狭い朱肉タンク内(試作品では直径10.4ミリ)ではショックが加わらない限り流動しなくなり、横にしたり逆さにしても、気泡が朱肉インク内や、朱肉インキと朱肉タンク(10)の内壁の間に入らない。
【0034】
したがって朱肉インキは通液穴(16)を通り、下貯液体(5)に毛細管作用により吸収され、体積の減った朱肉タンク(10)内の朱肉インキは大気の圧力により上部に押し上げられ、常に下貯液体(5)に吸収され続ける。
【0035】
そして流動性低下材(7)は朱肉インキの減少にともない収縮し、圧力を加えられなくとも流動性低下材(7)自体に毛細管作用が発生し、その吸引力が下貯液体(5)の吸引力を越え通液穴(16)に空気が侵入するまで朱肉インキを供給し、内部の朱肉インキの残留量は、フェルトやスポンジを使用した定形を有し体積がほとんど変化しない吸蔵体を使用した場合に比べ少なく、したがって体積が小さく、また一定の圧力を加える事しかできない印鑑ケースに内蔵する朱肉皿でも、実務で使用しても不便と感じないほどの捺印可能回数を得ることができる。
【0036】
繊維と朱肉インキを組み合わせる事から、この流動性低下材は吸蔵体とにているが、一般の吸蔵体は定形を有し、毛細管現象を利用して繊維や気泡室の間に朱肉インキを蓄えるが、この流動性低下材は、朱肉インキが多いときには、朱肉インキの量に対して繊維の量が少なく、毛細管現象の限界(液体に触れた際その液体を吸収しようとする現象の限界、もしくは繊維と繊維が引きつけあおうとする現象の限界と考える)を超え、朱肉インキに含まれいる状態であり、不定形で体積が大きければ繊維を含んだままで流動し液体としての性格を有し、朱肉インキの減少に比例してその体積もある程度まで減少する事から、この方法はグラスファイバーや鉄筋コンクリート、地滑り防止用の芝生の根など強度の不足する物質に、細長い丈夫な物質を含ませることにより強度を上げる方法に属すると思われ、一般の吸蔵体の概念には当てはまらないと考える。
【0037】
そして、朱肉タンクに流動性低下材を含んだ朱肉インキを入れ、パッキンを設置した状態(図14)の朱肉カートリッジを約1.5メートルの高さからタイルの上に落とす試験を繰り返した所、衝撃により朱肉インキが流動しパッキンに接触し(図15)、さらに衝撃が加わった際や、まれに衝撃による反動で激しく回転した時にはパッキン全体に朱肉インキが接触し、朱肉インキ内部に空気を取り込んでしまう(図16)事が確認された。この状態(図16)では空気が膨張した場合、留液室や印面に朱肉インキが押し出されてしまい、空気の膨張が大きい場合には朱肉インキが朱肉カートリッジの外に漏れ出す。
【0038】
このような事態に対応するために朱肉インキの底に朱肉タンクの直径よりやや小さい直径をもつ過流動防止シール(8)を配置する。朱肉インキはある程度粘着性をもっているため過流動防止シール(8)は朱肉インキに張り付き、流動性低下材を含んだ粘度の高い朱肉インキは質量の軽い材料(試作品の場合ポリエチレンの薄膜を使用)のシールの場合ショックが加わってもはがれたり、朱肉インキに沈むことはなく、シールの裏側に朱肉インキがほとんど回り込まない。
【0039】
過流動防止シールを張られた朱肉タンク内の、流動性低下材を含んだ朱肉インクは衝撃が加わり、ある程度流動してもそれ以上は過流動防止シールに妨げられ、流動せずパッキン全体に朱肉インキが接触する事はない。そしてシールの直径を朱肉タンクの高さ以上に設定してやれば過流動防止シールが朱肉タンク内で反転することもない。(図17)(図18)
【0040】
そしてこの朱肉インキに流動性低下材を含ませ、過流動防止シールを張る仕組は小型の朱肉タンクを複数個並べるような方法をとれば卓上型の朱肉皿にも応用が可能と考える。
【0041】
そして流動性低下材(7)を含んだ朱肉インキを入れ、過流動防止シール(8)を設置した後、パッキン(9)を設置する。そのパッキン(9)は空気の流通は抵抗なく行われるが朱肉インキがパッキン(9)に達した時には朱肉インキの表面張力によりその穴を通過しない程度の大きさをもつ穴(試作品の場合0.5ミリ程)を複数個開ける。
【0042】
パッキンを設置した後、通気穴(19)をもつ朱肉皿支持体(13)を接着する。その朱肉皿支持体(13)はショックが加わりパッキンの穴から朱肉インキが漏れた際に備えての留液室(18)をパッキン(9)との間に形成する。
【0043】
そして、朱肉皿主部(12)の下部はは朱肉皿主部(12)上部のの直径より大きな直径をもち、実願20200080286の印鑑ケースに内蔵する朱肉皿の朱肉皿周囲の突起(24)の役割をもつ。
【0044】
《効果案の効果》
本発明は、上記したように構成されているため、次に記載する効果を奏する。
特申者整理番号KK03の朱肉皿に比べ部品数が少なく、高価な金型を使用し加工する台バネを必要としないためコストを下げることができる。
【0045】
朱肉タンクをもつ朱肉皿を高度の変化や温度の変化による朱肉タンク内の空気の膨張による印面に体する朱肉インキの供給量の変化や漏れ出ることを防ぐ。
【0046】
朱肉面が印鑑の刻面の面積をやや上回る程度の面積の朱肉皿でも擦り減った印鑑の刻面の周囲に朱肉インキを付着させることができる。
【0047】
朱肉タンクをもつ朱肉皿でも印鑑の刻面により周囲に朱肉インキが過剰に付着しない朱肉皿を提供できる。
【0048】
朱肉タンクをもつ朱肉皿が使い初めから良好な捺印が可能となり、使用開始後、ある程度キャップを開けた後でも良好な捺印を得ることができる。
【0049】
朱肉インキの供給量が安定しており、実願20200080286の印鑑ケースを使用することにより、卓上型の朱肉皿を使用するように刻面を朱肉皿に押し付ける圧力を調節したり、刻面の朱肉インキの付着量を気にする事なく印鑑ケースのキャップを取るだけで良好な捺印が可能となる。
【0050】
従来の吸蔵体をもつ朱肉皿に比べ、捺印可能回数を増やすことができる。

《Technical field to which the invention belongs》
The present invention relates to a vermilion dish.
[0002]
《Conventional technology》
[0003]
Conventionally, a vermilion dish has a structure in which vermilion ink is absorbed by utilizing the capillary action of an occluding body such as cotton or sponge, and a surface cloth is disposed on an adjusting body or a cushion body.
[0004]
Therefore, when stamping, the stamp face of the seal is pressed against the stamp face to press the occlusion body, and the vermilion ink of the occlusion body is exuded onto the stamp face, and the vermilion ink is appropriately adhered to the stamp face of the seal stamp and stamped. Then, the amount of ink oozing into the surface cloth at a constant pressure is proportional to the amount of ink contained in the occluding body.
[0005]
Therefore, in order to obtain a good seal by applying a certain amount of vermilion ink to the engraved surface of the seal, the pressure for pressing the engraved surface on the stamped surface should not be changed in accordance with the change in the amount of vermilion ink contained in the occlusion body. Not be. That is, when the content of vermilion ink in the occlusion body is large, the cut surface must be lightly pressed, and as the content of the occluder decreases using vermilion ink, the cut surface must be strongly pressed.
[0006]
It is a type of stamp that presses the button on the bottom of the cap when pressing the button on the bottom of the cap when using the table-top red plate with the body of the seal in hand or when using the movable red plate inside the cap Although it is possible in the case (for example, Japanese Utility Model No. 2542307, JP-A-11-34463, JP-A-2000-229466, etc.), the pressure for pressing the cut face is adjusted according to the decrease in the content of the vermilion ink in the occlusion body. Without it, a good seal cannot be obtained, and in order to surely obtain a good seal, it is necessary to confirm the amount of red ink applied.
[0007]
In addition, a cylindrical seal case having a fixed red plate inside the cap (for example, Japanese Utility Model Publication No. 56-19532, Japanese Utility Model Application No. 62-102662, etc.) or a cylindrical type provided with a spring between the bottom of the cap and the movable red meat plate. In the seal case (for example, Japanese Utility Model Publication No. 300178, JP-A-11-129498), the pressure cannot be adjusted.
[0008]
Even if a cylindrical seal case body is provided with a mechanism that pushes out the seal body such as a screw type, in the case of a seal case with a fixed reddish dish, the pressure can be adjusted, but the reddish body of the occlusion body It is cumbersome to adjust according to the decrease in the amount of ink. In the case of a seal case having a spring below the vermilion plate, a large effect cannot be obtained because the vermilion plate is only pushed down.
[0009]
Then, a method of supplying vermilion ink to a stamp surface by adding vermilion ink to an occluding body such as cotton or sponge like a general vermilion dish, and applying pressure to the occluding body, requires a certain amount of ink on the occluding body. When ink is included, the ink will excessively seep to the surface with just a little pressure and the seal will become unclear, so that the occluder can contain only less than the amount of ink that can be contained by capillary action. In addition, in the case of the seal application of the Japanese Patent Application No. 20200080286, pressure is always applied to the stamp surface except at the time of stamping. We believe that there is a risk that the stamp will seep out and the seal will become unclear, and it is necessary to further reduce the content of vermilion ink. Therefore, there is no problem with a table-top vermillion dish with a large volume of vermilion plates, but it is difficult to obtain the number of times of imprinting that would not be inconvenient when used in practice with a small volume vermillion plate built into a seal case .
[0010]
Moreover, the amount of vermilion ink in the occlusion body is reduced, and even if pressure cannot be supplied sufficiently to the stamp surface, vermilion ink remains in the occlusion body and cannot be used efficiently.
Therefore, in order to supply the vermilion ink stably to the stamp surface even if printing is continued to some extent, and to increase the number of times that can be printed, the occluder has a structure that does not receive pressure and has an occluding body containing vermilion ink in a saturated state Vermilion plates or vermilion plates with vermilion ink tanks are considered to be effective, and vermilion plates with vermilion tanks have been devised (Japanese Utility Model Laid-Open No. 6-42200).
[0011]
However, a prototype similar to this idea and a prototype with a low-density sponge installed in a vermilion tank, a felt penetrated with a larger through-hole, and a vermilion ink supplied to the cushion body were created. When the experiment was performed on the seal case of Japanese Patent Application No. 20200080286, the following problems became apparent.
[0012]
This vermilion cartridge is housed in a seal case without a seal inserted, and is supposed to be sold separately for replacement, and is expected to be stored for a minimum of several weeks to several years, that is, manufactured Until the stamp is used, pressure is not applied to the stamp surface for a long period of time.Since the liquid conductor and cushion body without pressure are large in volume and low in density, use red ink to fill the capillary action of the material to the maximum. When absorbing the saturated occlusion material and vermicelli ink supplied from the vermilion tank, when compressed, the contained vermilion ink is pressed out, and in the small vermilion plate with the stamp face used for this seal case, Since the vermilion ink cannot escape to the surroundings, it seeps into the cloth and makes the seal unclear.
[0013]
Once used, they can be stored for months or years with the cap closed, that is, under pressure. The red meat dish, which is characterized by supplying the red ink without being compressed and having an occlusion body containing the vermilion ink in a saturated state, or having a vermillion tank, is saturated with the red ink, unlike a red meat plate having a general occlusion body. Sponge with a low density of state or vermilion ink in vermilion tank has low power to retain vermilion ink such as capillary action. Vermilion ink oozes on the cloth and the seal becomes unclear.
[0014]
In addition, the area around a seal that has been used for a long period of time is often worn away.If you use a table-top vermilion dish with a large seal surface, when you press the seal on the seal surface, the seal surface around which the seal is pressed will rotate. Red ink is also applied around the seal that has been pulled down and sunk into the shape of a seal, but is applied to a seal plate with a seal that is close to the diameter of the seal built into the cylindrical seal case. When the stamped surface is pressed by the surrounding stamped surface and is not pulled by the surrounding stamped surface, and if it is built into a cylindrical stamped case, the angle at which the stamped surface of the stamp is pressed against the stamped surface as when using a tabletop vermilion dish is used. Since it cannot be changed, there is a tendency that vermilion ink does not easily adhere around the worn seal.
[0015]
If a thick and soft cushion body is used to cope with this, a large amount of ink contained in the cushion body is released to the vermilion surface when the cushion body is pressed, resulting in a problem that the seal becomes unclear.
[0016]
And in the case of a vermilion dish with a vermilion tank built in, as the vermilion ink in the tank decreases, air enters the tank and goes over the mountain when carrying and moving, a seal placed in a cold office. When the pressure inside the tank becomes higher than the outside pressure, such as when putting the case in a warm pocket, the air inside the expanded vermilion tank begins to press vermilion ink onto the stamp surface, and the ink supply to the stamp surface becomes excessive, resulting in improper marking. It was confirmed that leaked red ink came out of the seal case and contaminate the pockets, especially in a passenger aircraft where the air pressure was reduced to an altitude of 2,000 meters.
[0017]
To deal with this, various prototypes were created and tested, such as having a distillate chamber using the effect of surface tension at the bottom of the red meat dish, but the distillate chamber was large enough to cope with the pressure drop in the passenger aircraft. The larger the size, the smaller the size of the vermilion dish, the smaller the volume of the vermilion tank, the less the number of times it can be stamped, and the higher the viscosity of the vermilion ink that flows into the distillate chamber, even if the pressure returns to a certain level. Can remain in the distillate chamber, so if the air pressure changes repeatedly, such as when you get on the elevator every day, the distillate chamber will be filled with vermilion ink and may leak to the outside. Was.
[0018]
《Problems to be solved by the invention》
It is small enough to be built into a seal case, and the number of times that it can be printed is increased compared to a red meat dish with the same volume and a general structure. To solve the following problem that occurs when a vermilion tank is built in.
Ensure that the ink of the vermilion ink is not transmitted from the vermilion tank to the cushion body even if it is stored for a long time without applying pressure to the stamped surface of the vermilion dish.
Good stamping is possible even if stored for a long time in a state where pressure is applied to the stamp surface of the vermilion dish. Even with a vermilion dish whose seal face is close to the diameter of the engraved face of the seal, vermilion ink is applied around the engraved face of the seal where the perimeter of the carved face has been somewhat reduced.
Even if the air inside the vermilion tank expands in the vermilion dish containing the vermilion tank in a general living environment, the supply amount of vermilion ink does not change.
[0019]
《Means for solving the problem》
The inventor has applied for a device relating to the present invention (Japanese Patent Application No. 2001007885) (Japanese Patent Application No. 20200080286) (Japanese Patent Application No. KK03, KK05).
This vermilion cartridge has been researched and developed for a seal case of Japanese Utility Model Application No. 20200080286.
[0020]
The red meat plate (FIG. 1) of the present invention is a seal (1), a surface cloth (2), and a brushed body (3) for protecting the stamp surface and preventing the fingertips from being stained when the red cartridge is pushed into the seal case cap. , Upper stored liquid (4), lower stored liquid (5), valve seal (6), vermilion ink (22), fluidity reducing material (7) contained in vermilion ink (22), overflow prevention seal (8) , A packing (9), a red meat plate main part (12) having a partition (11) for forming a red meat tank (10), and a red meat plate support (13).
[0021]
The lower storage liquid (5) is placed above the partition (11) of the main part of the vermilion dish (12). The lower storage liquid (5) is made of cloth or the like that easily absorbs vermilion ink and has a hole in the center. An upper liquid storage (4) having a liquid-impermeable valve seal (6) such as a thin film of silicon rubber adhered to the lower center thereof is placed thereon. The lower storage liquid (5) and the upper storage liquid (4) are made of a material such as a densely woven cloth that loses air permeability when it contains vermilion ink.
[0022]
The raised body (3) is placed thereon. The lower part of the raised body (3) and the center of the upper stored liquid (4) are connected with an adhesive. The brushed body is made of a synthetic fiber, such as nylon, which is hard to penetrate the ink and has elasticity. The brushed body forms a plane of mesh (14) on the upper surface (20) of the brushed body and the lower surface (21) of the brushed body. A fabric in which the fibers (15) between the lower surfaces are arranged vertically in a plane at a distance where the capillary action does not occur, and the fibers (15) do not come into contact with each other in a state where they are not pressed, or come into contact at the middle portion or more. use. Fabrics woven from nylon and other synthetic fibers are unlikely to lose their resilience, and the brushed body used in the prototype currently under test will continue to be pressed and the fibers will fall to some extent, but will not deform further Since the function as a raised body is not lost, it can be used for a vermilion dish built in a seal case that always presses the cushion body as in the seal case of Japanese Utility Model Application No. 20200080286. (The inventor has applied for a patent for a red meat dish with a brushed body.
[0023]
Then, a top cloth (2) having a thickness such that the mesh of the raised body (14) does not affect the uniform attachment of the vermilion ink to the engraved face of the seal is placed on the raised body (3).
[0024]
With the above configuration, in a state where no pressure is applied, the vermilion ink (22) in the vermilion tank (10) reaches the opening (17) above the liquid passage hole (16) of the partition (11) by capillary action. The vermilion ink reaching the opening (17) stops at the opening (17) due to surface tension, and the opening (17) is in contact with the lower storage liquid (5), the valve seal (6), and the upper storage liquid (4). Therefore, even if the vermilion cartridge is stored for a long period of time, vermilion ink is not supplied to the lower storage liquid (5) or the upper storage liquid (4), but the vermilion ink is excessively supplied to the surface cloth (2), and the seal becomes unclear. If the structure above the valve seal (6) is pulled upward at the time of production and shipment and the distance from the opening (17) of the liquid passage hole (16) is increased, the function becomes more reliable. (FIG. 12)
[0025]
In use, pressure is applied to the surface cloth (2) by the cut face of the seal to compress the raised body (3) and at the same time depress the valve seal (6), and the valve seal (6) opens the liquid passage hole. Even if the cloth (2) is stored for a long time in a state where the cap is closed, that is, the cloth (2) is pressurized by the engraved face of the seal in order to close the portion (17) and shut off the supply of vermilion ink. The vermilion ink does not exude and the seal does not become unclear. (FIG. 13)
[0026]
When the cap is removed and no pressure is applied to the outer cloth (2), the brushed body (3) woven of elastic synthetic fiber such as nylon has a strong restoring force and returns to its original state. The valve seal (6) connected to the lower surface (21) of the raised body with the (4) interposed therebetween is lifted and separated from the opening (17) of the liquid passage hole (16). However, since the distance between the opening (17) and the valve seal (6) is short and the lower storage liquid (5) has no air permeability, the high-viscosity vermilion ink does not separate from the valve seal (6), and the opening (17). The red ink (22) drawn out from the main body (12) of the red meat plate and the valve seal (6) reaches the lower storage liquid (5), and reaches the lower storage liquid (5) because the valve seal (6) is thin. ) And the periphery of the upper storage liquid (4) do not separate, the lower storage liquid (5) and the upper storage liquid (4) absorb the vermilion ink from the periphery of the valve seal (6), and the lower surface (21) of the raised body is Absorbs vermilion ink until capillary action is saturated. In addition, since the upper stored liquid (4) and the lower stored liquid (5) do not have air permeability, no air enters between the partition (11) and the valve seal (6), and the fluid-reducing material (7) contained in vermilion ink. Even if a capillary action occurs, the stored liquid is kept in red ink (22) until the suction force by the capillary action of the fluidity reducing material (7) exceeds the suction force of the stored liquid and air enters the liquid passage hole (16). Continue to absorb. (FIG. 14)
Although this function can be obtained even if the valve seal is directly adhered to the lower part of the raised body, it is considered that it is desirable to provide the upper liquid storage in order to more reliably prevent air from entering.
[0027]
Even if the lower storage liquid (5), the upper storage liquid (4), and the lower surface (21) of the raised body are saturated with capillary action, the fibers inside the raised body (3) that are not pressed do not generate capillary action. Since the ink is arranged in the vertical direction with respect to the plane at a distance, the ink does not absorb the vermilion ink, and the vermilion ink is not supplied to the upper surface (20) or the top cloth (2) of the brushed body.
[0028]
However, if the vermilion cartridge is laid down in that state and left for a long time, the perimeter of the upper storage liquid (4) or the lower surface (21) of the raised body and the inner wall of the vermilion plate main part (12) are gradually in contact with each other. Ink seeps out and reaches the cloth (2) along the inner wall of the main part of the vermilion dish (12). However, in the trial of the prototype, the leakage of vermilion ink does not affect the stamping in about two days, so it is a tabletop for work. Even if the cap is not closed for a day when used together with a mold vermilion dish, the cap should be closed at the end of work, so there is no practical problem. Further, it is considered that leakage of the vermilion ink can be further suppressed by punching out the raised body or the stored liquid by heat cutting and dissolving the fibers around them so that the capillary action is not generated only in the surroundings.
[0029]
Then, when pressure is applied to the surface cloth (2) and the raised body (3) is pressed, the fibers (15) inside the raised body (3) are pressed, and the fibers are brought into a lying state, and the fibers come into contact with each other to generate a capillary action. Then, the vermilion ink contained in the lower part of the raised body (3) is supplied to the upper surface (20) of the raised body and the top cloth (2). The brushed body (3) has a large change in volume when pressed and has excellent cushioning properties, but since it does not contain vermilion ink inside, the vermilion ink pushed out when pressed is the same as the lower liquid (5). Only the vermilion ink contained in the upper storage liquid (4) and the lower surface (21) of the raised body has a small amount, and escapes to the space of the mesh (14) on the upper and lower surfaces of the raised body (3), and the cloth (2) The bleeding seal is not unclear.
[0030]
Also, since the brushed body (3) does not contain vermilion ink even when its volume is large, there is no need to consider vermilion ink that is released when compressed like a cushion body of a general vermilion dish. Can increase the travel distance of the ink, and use the friction between the periphery of the table cloth and the inner wall of the main part of the vermilion dish to generate the function of attaching vermilion ink to the perimeter (24) of the cut surface that has been reduced. Can be.
(For this function, the inventor has applied for a patent, and has reference number KK03.)
In addition, if a brushed body is used as a table spring for the KK03 red meat cartridge already applied for, a closed plate fixed to the upper surface can be penetrated downward, eliminating the need for a separator and reducing material costs, resulting in significant cost reduction. Can be expected.
[0031]
Then, the following method is used to cope with a change in the atmospheric pressure generated when the vermilion tank is provided.
[0032]
A high-viscosity vermilion ink is put into the vermilion tank (10) so as not to include air. The vermilion ink having a high viscosity passes through the liquid passage hole (16) and reaches the opening (17), and does not leak due to the action of surface tension. Into the vermilion ink, a small amount of fluidity reducing material (7) of fibers having low elasticity, such as ultra-fine fibers and absorbent cotton, which do not have a fixed form and does not cause capillary action, is diffused. (In the case of a prototype, the absorbent cotton used in a 6 mm-high vermillion tank is compressed to about 0.1 mm, and the volume change of vermilion ink containing no fluidity reducing material and vermillion ink containing Can't confirm)
[0033]
Among the high-viscosity vermillion inks, the high-viscosity vermillion inks containing the fluidity-reducing material (7) stick to the periphery of the fiber, have low fluidity, and become muddy. In the tank (10.4 mm in diameter in the prototype), it will not flow unless a shock is applied. Even if it is turned sideways or upside down, bubbles will be in the vermilion ink or between the vermilion ink and the inner wall of the vermilion tank (10). Do not fit.
[0034]
Therefore, the vermilion ink passes through the liquid passage hole (16), is absorbed by the lower reservoir liquid (5) by capillary action, and the vermilion ink in the reduced volume vermilion tank (10) is pushed upward by atmospheric pressure, and is constantly pushed upward. It continues to be absorbed by the lower storage liquid (5).
[0035]
The fluidity-reducing material (7) shrinks as the vermilion ink decreases, and even if pressure is not applied, a capillary action occurs in the fluidity-reducing material (7) itself, and the suction force of the fluid-reducing material (5) decreases. Supply the vermilion ink until the air enters the liquid passage hole (16) exceeding the suction force. The residual amount of vermilion ink inside uses a fixed form using felt or sponge and uses an occlusion body whose volume hardly changes. Even with a reddish dish built in a seal case that is smaller than that in the case and therefore can only apply a certain pressure and can be applied to a seal case, it is possible to obtain the number of times that it can be stamped such that it is not inconvenient to use it in business.
[0036]
Because of the combination of fiber and vermilion ink, this fluid-reducing material is in the occlusion body, but the general occlusion body has a fixed form and stores vermilion ink between fibers and bubble chambers using the capillary phenomenon. However, this fluidity reducing material, when the amount of vermilion ink is large, the amount of fibers is small relative to the amount of vermilion ink, and the limit of the capillary phenomenon (the limit of the phenomenon of trying to absorb the liquid when touching the liquid, or It is considered to be the limit of the phenomenon that fibers and fibers tend to attract each other), and it is contained in vermilion ink.If it is irregular and large in volume, it will flow with containing fibers and has the character of a liquid. Since the volume decreases to a certain extent in proportion to the decrease in ink, this method can be used for materials that lack strength, such as fiberglass, reinforced concrete, and lawn roots to prevent landslides. It seems to belong to a method of increasing the strength by including, considered in the concept of a general occlusions not apply.
[0037]
Then, a test was repeated in which a vermilion ink containing a fluidity-reducing material was put into a vermilion tank, and a vermilion cartridge in a state where a packing was installed (FIG. 14) was dropped on a tile from a height of about 1.5 meters. The vermilion ink flows due to the impact and comes into contact with the packing (Fig. 15). When the impact is further applied, or in rare cases when the vermilion rotates violently due to the impact, the vermilion ink contacts the entire packing and air is taken into the vermilion ink. (FIG. 16). In this state (FIG. 16), when the air expands, the vermilion ink is pushed out to the distillate chamber and the stamp surface, and when the air expands greatly, the vermilion ink leaks out of the vermilion cartridge.
[0038]
To cope with such a situation, an overflow prevention seal (8) having a diameter slightly smaller than the diameter of the vermilion tank is arranged at the bottom of the vermilion ink. Since the vermilion ink has a certain degree of tackiness, the overflow prevention seal (8) is attached to the vermilion ink, and the higher viscosity vermilion ink containing the material with reduced flowability is a lighter material (a thin film of polyethylene is used for the prototype). In the case of the seal, the ink does not peel off or sink into the vermilion ink even if a shock is applied, and the vermilion ink hardly spills on the back side of the seal.
[0039]
The vermilion ink containing the fluidity-reducing material in the vermilion tank covered with the overflow prevention seal receives an impact. There is no ink contact. If the diameter of the seal is set to be equal to or greater than the height of the vermilion tank, the overflow prevention seal will not be inverted in the vermilion tank. (FIG. 17) (FIG. 18)
[0040]
Then, it is considered that the mechanism for adding the fluidity-reducing material to the vermilion ink and applying an overflow prevention seal can be applied to a table-top vermilion plate by adopting a method of arranging a plurality of small vermilion tanks.
[0041]
Then, after inserting a vermilion ink containing a fluidity reducing material (7) and installing an overflow prevention seal (8), a packing (9) is installed. The packing (9) allows air to flow without resistance, but when the vermilion ink reaches the packing (9), a hole having a size such that it does not pass through the hole due to the surface tension of the vermilion ink (0 in the case of a prototype). 0.5 mm).
[0042]
After installing the packing, the vermilion dish support (13) having the ventilation holes (19) is bonded. The vermilion dish support (13) forms a distillate chamber (18) between itself and the gasket (9) in preparation for the case where vermilion ink leaks from a hole in the gasket due to a shock.
[0043]
The lower part of the vermilion plate main part (12) has a diameter larger than that of the upper part of the vermilion plate main part (12), and the protrusions (24) around the vermilion plate of the vermilion plate incorporated in the seal case of Japanese Utility Model Application No. 20200080286. Has the role of.
[0044]
《Effect of effect plan》
Since the present invention is configured as described above, the following effects can be obtained.
The number of parts is smaller than that of the red meat plate with the special applicant reference number KK03, and the cost can be reduced because an expensive die is not required and a table spring is not required.
[0045]
It is possible to prevent a change in the supply amount of the ink of the vermilion ink applied to the stamp surface due to the expansion of the air in the vermilion tank due to a change in altitude and a change in temperature, and a leakage of the vermilion plate having the vermilion tank.
[0046]
Even with a vermilion dish whose vermilion surface is slightly larger than the area of the engraved surface of the seal, vermilion ink can be adhered around the engraved surface of the imprinted seal.
[0047]
Even a vermilion plate having a vermilion tank can provide a vermilion plate in which vermilion ink does not excessively adhere to the periphery due to the engraved face of the seal.
[0048]
Good stamping is possible from the beginning of use of the vermilion dish with the vermilion tank, and good stamping can be obtained even after opening the cap to some extent after the start of use.
[0049]
The supply amount of vermilion ink is stable, and by using the seal case of Japanese Utility Model Application No. 20200080286, the pressure for pressing the carved surface against the vermicelli plate can be adjusted to use a table-top vermilion plate, A good seal can be obtained simply by removing the cap of the seal case without worrying about the amount of ink adhesion.
[0050]
The number of times that can be stamped can be increased as compared with a vermilion dish having a conventional occlusion body.
