Description
本發明關於一種具有多樣特徵的口腔保健用具,此等特徵可包括一用來清潔使用者口中之軟組織表面的清潔器、牙齒清潔或牙齒處理元件、可動清潔特徵部、振動機構、及/或握把抓持特徵部。
當今存在著具有靜止及/或機械傳動可動清潔元件的多樣牙刷組態。此等傳統牙刷專用於牙齒清潔/磨光作業且通常包含一針對此等清潔/磨光作業的頭部以及一握把部分。該頭部通常有一平坦或稍作變化的表面,該等清潔元件被附接至該表面,或者用於該等清潔元件之機械傳動可動載體被附接至該表面。
當今存在著當作去除沈積在使用者舌頭上之細微碎屑之裝置的刮舌器。傳統刮舌器是針對刮乾淨使用者舌頭的單一目的之獨立裝置。此等傳統裝置通常包含一握把以及不含其他清潔元件的刮擦器部分。
使用者藉由抓住握把部分來操縱傳統牙刷及刮舌器。此等握把通常是一較剛硬材料之簡單直線條棒,其對於使用者來說既不舒適亦不易於操縱。由於此等裝置一般是在潮濕條件下使用,其握把在使用中經常會滑。
許多人每天使用多種口腔保健用具譬如牙刷及刮舌器以完成多重口腔保健工作。舉例來說,一使用者可使用一牙刷清潔牙齒,然後用一刮舌器從舌頭去除碎屑。
然後該使用者可能再次使用牙刷來更進一步清潔舌頭。因此,使用者可能在一潮濕環境中於單次期間輪番使用多樣口腔保健用具。
傳統牙刷具有從一剛性頭部伸出的清潔元件。牙齒和牙齦天生就有一複雜輪廓。因為清潔元件對於刷頭部之附接的剛性本質,清潔元件之取向是不可撓的且因此傳統牙刷無法提供牙齒和牙齦之最佳清潔效果。傳統牙刷因而很難接觸到離刷頭部較遠之牙齒的區域、包括牙齒之間的鄰接空間。
本發明關於一種提供數項優點且可用於多重功能的口腔保健用具。在本發明之一實施例中,提出一種口腔保健用具,其具有複數個從頭部伸出的清潔元件,該等清潔元件被附接至一可撓地附接於該頭部的支撐件。該等清潔元件可包括前傾清潔元件及/或後傾清潔元件。該等清潔元件可更進一步在該支撐件之一中央部分包括一中央支撐部。
本發明之實施例可為多功能的且包含有利組合中之多種特徵組合。某些實施例包含一軟組織清潔器與牙齒清潔特徵部的組合及/或一軟組織清潔器與該握把上之增進使用者對其抓持和操控能力之抓持特徵部的組合。該等實施例可為手動或機械傳動裝置、或二者之組合。
本發明關於一種口腔保健用具,其包含:一握把;一連接於該握把且具有一底座結構的頭部;及複數個附
接至該底座結構的清潔元件,該複數個清潔元件的每一個清潔元件之一端係互相彼此連接,其中該複數個清潔元件之至少一個清潔元件係一螺捲刷毛;複數個彈性體壁群組附接至該底座結構,該複數個彈性體壁群組共同界定沿該頭部的一縱向軸線而設置的複數個大致封繞組態;每一群組內的該彈性體壁係藉由一間隙而與一相鄰的彈性體壁分隔,且每一大致封繞組態包含位於該頭部的縱向軸線之至少一間隙。
可選擇地,該口腔保健用具更包含設置於每一大致封繞組態內的一中央清潔元件。
可選擇地,該口腔保健用具更包含附接至該頭部的一第一表面之複數個組織清潔元件,其中該頭部包含一第二表面,該底座結構係形成於該第二表面,且該第一表面背對於該第二表面。
可選擇地,該口腔保健用具更包含一從該底座結構的第一表面伸出的第一承窩;一從該底座結構的第一表面伸出的第二承窩;一設置於該第一與第二承窩之間的第三承窩,該第三承窩藉由該第一承窩、第二承窩及至少一懸吊構件而支撐在該第一表面上方,一存在於該第三承窩的一底部表面與該底座結構的第一表面之間的間隙,該複數個清潔元件係從一或多個的第一、第二及第三承窩伸出。
依據本發明之該口腔保健用具,該一第一承窩的頂部部分、該第二承窩的頂部部分、該第三承窩及該至少
一懸吊構件係為一體總成,其係大致附接至該底座結構。
依據本發明之該口腔保健用具,該第一承窩、該第二承窩及該底座結構包含一剛硬材料;及該至少一懸吊構件包含一彈性材料。
依據本發明之該口腔保健用具,該第一承窩相對於該底座結構係大致不可動;該第二承窩相對於該底座結構係大致不可動;及該第三承窩相對於該底座結構係可動。
依據本發明之該口腔保健用具,該第三承窩具有一橫向寬度,其係大致等於該底座結構的一橫向寬度。
以下實施例就提供多樣特徵及功能之多種口腔保健用具組態的樣式說明本發明的觀點。雖說這些觀點係就特定範例實施例的內容來揭示,本發明提出一種含有本文所述特徵之一或多者的口腔保健用具。該口腔保健用具可包含一在本說明書一實例組態中提及的第一特徵以及一在本說明書另一實例組態中提及的第二特徵。
換言之,本發明涵蓋以多種組合混合並適配來自本說明書各實施例的特徵變成單一個口腔保健用具。本發明因而使選擇清潔元件組態、組織清潔器組態、握把特徵、抓持特徵、機械驅動特徵、材料及取向等之一組合以達成希望結果變得可行,並且得到附帶口腔保健好處,譬如強化清潔效果、牙齒磨光、牙齒美白、舌頭清潔、牙齦按摩等。
〝清潔元件〞一辭希望是以一般性的廣義使用,其可包括用以清潔、處理、磨光、美白、刮擦、擦洗等的元件。清潔元件可包括但不限於尼龍或纖維刷毛、按摩元件、及被排列成一圓形橫截面形狀或包含直線部分或正弦狀部分之任何類型期望形狀的彈性體指狀件或壁。在刷毛的形式中,清潔元件可經由模製中植入(in-molded)技術固定於一可撓膜片或織物,藉由將集束塊或區段延伸穿過可撓膜片中之適當開口而安裝集束塊或區段,或是其他機制。
本發明揭示多樣口腔保健用具組態。一種組態是一具有獨特地安裝於一口腔保健用具之頭部之多群組清潔元件的口腔保健用具,其安裝方式促成一些元件群組相對於被清潔的牙齒和牙齦之可撓取向。舉例來說,頭部之元件群組可合作〝包纏〞個別牙齒導致清潔/處理元件在牙齒之間較深入的穿透。此等組態舉例來說可藉由多組清潔元件相對於頭部以及相互間之獨立運動而提供有效的整體清潔效果。此組態暨其他組態將在下文說明。
圖1-4繪出一依據本發明一實施例之牙刷610。如圖所示,牙刷610包含一長形握把612且有一刷頭614連接至該握把且自此延伸。刷頭614被區隔成相互隔開的複數個獨立清潔區。如圖所示,該等清潔區包含一位在刷頭614之遠端且從刷頭主體部分930(圖4)往外突出的底座616。底座616包含至少一個、較佳複數個的清潔元件618。刷頭614更在刷頭614之近端包含一底
座或支撐構件620。清潔元件618亦從底座620往外延伸。
一對承窩622、624被安裝在納入底座616和620的清潔區之間。每一承窩具備至少一個且較佳複數個的清潔元件。如下文所述,承窩622、624的自由度高於底座616、620。在本發明之較佳實行方式中,承窩622、624是彈性構件,使得承窩清潔元件增添一超過大致靜止或不可動之清潔元件618的運動範圍。因為各清潔元件譬如藉由以一橫向方向完全橫越刷頭614延伸的渠道728相互隔開並且由於承窩622、624的彈性本質,清潔元件626可能能夠繞每一個別承窩之鉛直軸線360度旋轉。彎曲角度可由材料的彎曲能力決定。
牙刷610因而提供一刷頭614,其中前(遠端)區和後(近端)區處於一相對而言固定的位置,且其中清潔/處理元件譬如刷毛股618不具有任何額外運動度。但刷頭614之中間部分有兩區能夠360度旋轉的清潔元件626。
如圖4所示,刷頭614包含一支撐著底座和承窩的主體部分930。主體部分930及底座616和620較佳係由常見用來製造牙刷握把和刷頭的習知硬塑膠材料譬如聚丙烯製成。但承窩622、624被製造成有彈性的。在本發明之一較佳實行方式中,承窩622、624的彈性係藉由提供一從刷頭主體部分930伸出之小直徑樑932的方式達成。樑932結合到一薄墊或板934的底部內,該薄墊
提供一支撐區讓清潔元件626貼附其上。將清潔元件626安裝於支撐墊934的方式得利用多種清潔元件譬如刷毛及其他清潔材料以已知附接方法達成。
承窩622、624之期望可撓性或彈性藉由在多重射出成型程序期間將薄樑932包封於彈性材料936內而加強。彈性材料936的彈性致使樑932回復其原始形狀或起始位置。此回復作用在樑彎曲的反方向內造成一有效運動,其因為引起額外刷洗行程而有助於清潔牙齒。
如圖1、2和4最佳顯示,承窩622、624包含一被配置為朝向體部930的加寬部分。支撐墊934也被加寬。每一承窩有一居於每一承窩長度之縱向中段的窄或減徑中央部分938。因此,每一承窩大致呈蘑菇形狀。樑932可為任何適當形狀,譬如有一圓形、方形或任何其他會對該樑提供一小尺寸或小直徑以促進該樑之可彎曲性的幾何形狀的橫截面。彈性體936可被視為是一具有任何適當厚度的連續層,其如圖所示覆蓋刷頭614的整個中央區域使得承窩622、624均被當作相同彈性材料之部件納入。刷頭614包含承窩622、624的部分可被形成為與下文參照圖5和6說明之次級總成類似的獨立次級總成。
雖說本發明可被實行為具有單一個底座和單一個承窩且可被實行為此底座略有小於該承窩之可撓性,本發明較佳被實行為該底座是大致靜止或不可動的。此外,本發明較佳被實行為具有複數個此種底座及複數個承
窩。圖式繪出本發明之一組態,其中總計有四個獨立清潔區且承窩被定位在刷頭614的中央部分。本發明可被實行為其中之清潔元件在每一底座和每一承窩上包含複數個刷毛或線股的一種組態。
如圖3和4所示,每一底座616和620及每一承窩622和624可有一大致卵形外表面。該等底座及承窩是縱向對準的,但相互間以形成渠道728之凹處或開放區域隔開。亦如圖3所示,承窩的外表面或清潔元件攜載表面可大於底座的外表面或清潔元件攜載表面。
如圖2所示,清潔元件618和626之終端表面是錐狀的,使得清潔元件618之終端表面以一朝向刷頭614中央之方向往外推拔,同時清潔元件626之終端表面以一背離刷頭614中央之方向往外推拔。因此,就每一對底座和承窩616、622和620、624來說,每組清潔元件618及其相鄰組清潔元件626的最高點大致被配置為互朝對方。
任何適當形式的清潔元件均可被用在本發明之廣泛實行中當作清潔元件618和626。〝清潔元件〞一辭希望是如前所述以一般性的廣義使用。使用不同清潔材料做為牙刷之清潔元件可產生不同效果。在想要提供更好去污效果的作法中,得使用一類橡膠材料或彈性體搭配習知刷毛或是只用類橡膠材料或彈性體來〝亮白/美白〞牙齒。
應理解到對於清潔元件之特定說明僅是範例。本發
明得以相同或不同清潔元件組態〔譬如肘釘固定、免錨定集束(AFT)刷毛或是模製中植入技術(IMT)的刷毛等〕及/或與相同刷毛或清潔元件材料(譬如尼龍刷毛、螺捲刷毛、橡膠刷毛等)的多種組合實行。相似地,雖說圖2顯示清潔元件大致垂直於刷頭614之外表面,該等清潔元件當中一些或全部可為相對於刷頭614之外表面以不同角度傾斜。藉此有可能選取會達成特定希望結果之清潔元件組態、材料和取向的組合以實現附加的口腔健康益處,譬如加強的清潔牙齒光潔、牙齒美白及/或牙齦按摩。
圖5-6繪出本發明之另一實施例。牙刷1110A具有在指定區域內為刷毛1026A、1126A提供可撓支撐的能力。可撓性係由將刷毛束固持區1034A、1134A設計成板件並與莖狀部1038A、1138A結合形成蘑菇狀承窩的方式提供。蘑菇柄1038A、1138A被製作成可撓的以容許植有刷毛或清潔元件1026A、1126A之板件1034A、1134A在刷洗期間以不同方向移動,正如就圖1-4之可撓承窩所述。
圖5-6繪出牙刷1110A,更特定言之是刷頭1114A之清潔元件或刷毛攜載部分1023、1123。如圖5所示,刷毛或清潔元件攜載部分1023形成一起始次級總成。此次級總成係由將清潔元件1026A導入一模穴內且將一塑膠材料注入該模穴內的方式製成。隨著注入的材料冷卻,其將刷毛或清潔元件1026A永久地困住而形成一刷
或次級總成1023。
為達成一實用可撓性及適切刷毛束固持效果,包括板件1034A、莖狀部1038A及互連支撐件1025之刷毛保持部件或次級總成1023的部分較佳是聚丙烯(PP)與軟TPE之一混雜物。一旦該PP/TPE混雜物與刷毛1026A結合,即形成了次級總成1023。然後在二次射出循環期間使次級總成1023與一整個牙刷握把1112A和刷頭1114A包覆成形(overmolded)而形成如圖6所示的完整牙刷1110A。如果想要或有被要求,可首先製造沒有次級總成1123的整個握把1112A和刷頭1114A然後製造次級總成或刷毛固持部分1123。雖然以上已說明一IMT程序,次級總成亦可為利用一AFT程序形成,其中舉例來說清潔元件被熔融在一起然後被困在板件內。
應理解到圖5-6所示之本發明可被實行為刷頭1114A之所有部分包含可撓蘑菇狀區段而沒有較不可撓的底座部分譬如圖1-4之底座616和620。相似地,圖5-6之次級總成兩次射出技術可被用在圖1-4之實施例中用以將二個或更多中央承窩形成為一開始就獨立於刷頭1114A其餘部分製造的單一次級總成。成品牙刷會在二次射出成型程序中製成,其中具有互連承窩622、624之次級總成會被模製於以更剛硬材料製得的握把612及刷頭614。
如前所述,圖2例示清潔元件618和626之終端表面以一上下或鋸齒形方式呈錐狀。圖5-6顯示一替代推
拔,其中該等終端表面形成一順暢和緩凹面形狀。必要時可採用其他形狀,譬如使終端表面為一平坦形狀或是一凸面形狀以及如圖2所示之鋸齒形或上下形狀。相似地,圖1-4實施例以及圖5-6之清潔元件的終端可有多種形狀,譬如鋸齒形、凸形、凹形或平坦的。
圖7-25E示出本發明之額外實施例,其更進一步例示本說明書揭示之各種觀點、特徵及功能併入單一口腔保健用具組態內的可組合性。圖7-25E示出提供一具有獨立清潔元件群組之牙齒清潔器的口腔保健用具組態,該等清潔元件群組可各自被安裝在一固定底座或一可撓承窩上,且此等組態可在牙齒清潔器之外更提供一軟組織清潔器。該等組態可為電動或手動裝置,且握把可包含抓持特徵部。因此,圖7-25E之口腔保健用具整體而言包含就圖1-6有關可包含可撓承窩之清潔元件群組所做說明的觀點。但應理解到可將其他特徵搭配這些組態一起使用,譬如在共同待審專利申請案11/122,224號及10/768,363號中提到的機械驅動特徵(亦即本說明書所述各實施例之頭部可為振動式頭部)以及全說明書中說明之牙齒清潔特徵。
圖7-9例示一依據本發明另一實施例之口腔保健用具9910(譬如一牙刷)。如圖所示,牙刷9910包含一刷頭9914和一握把8103。握把8103可為依據2004年7月30日申請之美國專利申請案10/902,257號揭露的內容形成,該專利之內容以引用的方式併入本文中,然亦可使
用其他握把組態,譬如圖1-6所示握把612、1112A。刷頭9914與就圖1-6所述刷頭614大致相同,差別在於清潔元件9918以及被設置在刷頭上背對於該等清潔元件之一側上的適形輪廓9940。因此,刷頭9914大體上包含以一大致靜態組態分別支撐清潔元件9942和9944的底座616和620。刷頭9914亦包含被設置在該等底座之間用來分別支撐清潔元件9946和9948的承窩622和624。如同就圖1-6所述,承窩622和624能提供讓清潔元件9946和9948附接之可撓承座,且可能許可清潔元件9946和9948旋轉及/或振盪。
圖7示出一適形表面9940被設置在刷頭上背對於清潔元件之一側上。適形表面9940包含小丘9950和凹谷9952,藉以在刷頭之一背面上提供一起伏或波浪狀表面。表面9940可為較平滑的以供按摩口腔組織,如圖10及12-18所示,該表面可包含用來接合口腔軟組織的軟組織清潔元件並且對軟組織提供清潔效果。
圖9是刷頭9914之俯視圖,其示出搭配刷頭9914使用之牙齒清潔元件9918的一種組態。清潔元件9918可由彈性體壁構件、長條刷毛束、或其他類型的清潔元件構成,其可獨立撓曲。依此方式,清潔元件能夠提供牙粉之一受限受控流動,並且維持充分可撓性以經由清潔元件對於使用者牙齒提供更好清潔效果及對於使用者牙齦提供刺激效果。
清潔元件9918被定向為用來以一般希望施用方向
A(見圖8)接合於待清潔表面,該方向大致垂直於刷頭9914之面。然清潔元件9918包含與方向A對準(不傾斜)之清潔元件及相對於方向A歪斜(傾斜)之清潔元件的混合物。此等傾斜及不傾斜清潔元件之配置提供口腔表面之有效接合和清潔效果,此效果藉由可動承窩組態更進一步強化。安裝在承窩622和624上之清潔元件9946和9948適於以自其可撓支撐組態獲益的多樣方式接合使用者牙齒、牙齦及其他表面。因此,清潔元件9946和9948包含朝刷頭之末梢端傾斜的前傾元件9950以及朝握把傾斜的後傾元件9952。如圖所示,前傾元件和後傾元件9950、9952較佳被安置在其相應承窩之向前和向後側上,且更佳為被安置在承窩之轉角區域。此一位置和取向提高元件9950和9952會先於相應承窩上之其他清潔元件最早接合一待清潔表面的可能性,此促使相應承窩在其上剩餘清潔元件接合該表面時屈曲。
舉例來說,當口腔保健用具9910被往前移動致使刷頭9914引領著牙刷時,前傾元件9950會先於後傾元件9952或被設置在元件9950與9952間之其他清潔元件最早接合待清潔表面。元件9950之前傾角會在此等前傾元件接觸一待清潔表面同時牙刷往前移動的條件下促使承窩622和624向後彎曲。承窩之向後彎曲及其回應於該彎曲而產生的向前反彈作用增強被設置在該等承窩上之清潔元件9946和9948的清潔有效性。相較於清潔元件9954被設置成垂直於牙刷面且不前傾亦不後傾的替代實
施例,元件9950和9952之傾斜組態增進承窩之彎曲作用。
承窩之清潔元件9946和9948亦包含不傾斜清潔元件9954,其有利於穿透待清潔表面。此外,清潔元件9946和9948包含一對位在承窩中央部分的彎形直立壁9956。此等壁可為藉由一IMT或AFT程序形成為一密集刷毛束,或者可包括彈性體元件。其他組態亦在設想之中。該對中每一壁9956具有一與該對中另一壁之凹形側對向的凹形側。直立壁9956之彎形組態及背對凸形側增進牙粉在該口腔保健用具使用期間留在壁間的效果。此外,該彎形組態提供一對剛性壁,其在承窩之中央部位支撐承窩以防清潔元件9946、9948過度屈曲。
被設置在靜止底座616和620上之清潔元件9942和9944被建構為與可動承窩上之清潔元件9946和9948合作,並且用來有效清潔口腔表面。該等底座每一者包含一刷毛9960、一系列的直立壁9962、以及傾斜清潔元件9964、9966。刷毛9960大致是一不傾斜柱狀物,其有效穿透口腔結構(例如牙齒)間之間隙和凹穴。
直立壁9962之系列被排列為大致形成一朝向剩餘清潔元件9918的凹形壁。因此,前部底座616之凹形壁9962以其凹形側往後朝向握把,且後部底座620之凹形壁以其凹形側往前朝向剩餘刷毛9918。在此一組態中,對向凹形壁合作經由其盛裝牙粉之凹形形狀且經由形成凹形壁之直立壁間的小間隙(其減少牙粉經此流過)將
牙粉留在刷毛9918的場域內。此外,形成凹形壁之直立壁是在使用中對刷頭9914提供支撐效果且在使用者施予過大向下力時抗拒清潔元件過度屈曲的不傾斜清潔元件。
傾斜清潔元件9962和9964朝可動承窩622和624傾斜以與附接於該等承窩之清潔元件9946和9948合作來有效地清潔口腔表面。因此,後部底座620包含前傾元件9964,且前部底座616包含後傾元件9966。傾斜清潔元件9962和9964被設置為在可動承窩之一對相應傾斜清潔元件9950和9952以內互朝對方接近。因此,當該等承窩前後屈曲時,傾斜清潔元件9962和9964介於對應傾斜清潔元件9964和9966之間。此提供一類似於剪刀的動作,其增強清潔有效性且避免可能限制承窩運動的對向清潔元件9964、9966及9962、9964間之干擾。
以上就圖7-9之實施例及下文所述實施例的清潔元件較佳是利用此技藝中已知的AFT技術形成。此技術促成異於傳統肘釘固定垂直刷毛束之清潔元件構造的排列。藉由AFT技術,清潔元件之錨定端被熔在一起形成一清潔元件塊,然後此塊可被設置在具備各種尺寸、角度和取向的刷頭板上。因此,清潔元件塊大致被困在承窩結構內而非埋入一支撐介質內。
今參照圖10-13,其示出一依據本發明另一實施例之口腔保健用具10210。如圖所示,口腔保健用具10210包含一握把8103,一頭部10214具有附接於其第一側上
的清潔元件10218且具有一被設置在背對於該第一側之頭部第二側上的軟組織清潔器10280。口腔保健用具10210大致包含口腔保健用具9910之觀點及特徵,差別在於清潔元件之組態以及軟組織清潔特徵部。清潔元件10218主要包含直立壁,其可包括一彈性體元件,或者可藉由一IMT或AFT程序形成為一密集刷毛束。其他組態亦在設想之中。此等直立壁除了清潔效果更提供有利的牙齒擦拭磨光效果。清潔元件10218亦包含一中央柱狀清潔元件10270,其可為一刷毛,用於透入口腔表面。如圖10所示,每一中央清潔元件10270延伸超過同一承窩上與其相鄰的其他清潔元件。此外,中央清潔元件可有一尖頭末梢。因此,中央清潔元件10270有效地透入並接合口腔表面及表面間隙。
類似於圖4和7之組態,且如圖11所示,清潔元件10218之末梢或終端縮細,致使承窩在接合待清潔表面的同時分別被推往相鄰靜止底座。故在使用期間,清潔元件9948大致被偏往與後部底座620上之清潔元件9944接合,且清潔元件9946大致被偏往與前部底座616上之清潔元件9942接合。此偏動作用能與承窩因裝置移動中時傾斜清潔元件與清潔表面之接合而造成的移動一起發揮作用。底座622和624之加大移動及屈曲更進一步增強該口腔保健用具的清潔有效性。
軟組織清潔器10280包含複數個從頭部10214一第二側之一面10284伸出的突出部10281,其大致與牙齒
清潔元件10218之延伸方向反向。軟組織清潔器10280被設置在一適形表面上,譬如圖7所示之適形表面9940,其包含小丘9950和凹谷9952藉以在頭部之一第二面上提供一起伏或波浪狀表面。突出部10281可能是獨立模造並膠黏於該適形表面或是以其他方式附接。此外,其可為與頭部10214一體成形。突出部可為各自由一不同於其他突出部且/或不同於其他部分的材料製成。可將軟性材料譬如TPE或類似物固定於頭部10214以形成此等突出部。然一較硬材料或是被用來製造口腔保健用具的幾乎任何已知材料可能也適用於此等突出部。
突出部10281包含複數個小凸塊10282,其從適形表面9940伸出用以接合使用者口中的軟組織。突出部10281可具有多樣形狀、圖案、橫截面、組態等,且軟組織清潔器可具有多種突出部組態。
如圖13所示,小凸塊10282大致覆蓋一清潔器場域10288中的後部面10284,該場域從一背對於頭部下部處之後部底座620的區域延伸到一背對於頭部末梢部處之前部底座616的區域。此等小凸塊以一大致連續圖案分散於該清潔器場域。此清潔器場域包含緊鄰面10284之邊緣部分的小丘10290以及被設置在小丘之間且在該面之一中央部分的凹谷10292。此種小丘與凹谷的組態藉由在初始與使用者軟組織接觸時將外力集中在小丘部分而增強軟組織清潔器之有效性,此方式相較於一較平坦
組態能夠提高透入軟組織的效果。當使用者施加額外力量,凹谷接觸到軟組織以協助清潔這些軟組織。如果有過大力量施加,凹谷有助於限制過量透入。當凹谷區內之小凸塊接合於軟組織,其提供趕走已被小丘上之小凸塊之較深透入作用弄鬆的碎屑的附帶效果。因此,小丘和凹谷上的突出部協同作用在一開始弄鬆然後趕走使用者軟組織內的碎屑。
圖14和15示出一依據本發明之口腔保健用具的另一實施例10610。口腔保健用具10610大體上包含與口腔保健用具10210相同的觀點和特徵,差別在於軟組織清潔器10680上之突出部的組態。軟組織清潔器10680不是在整個清潔器場域上具有小凸塊而是只在小丘10288上包含小凸塊10282。代之為有多個脊狀部10294被設置在一些凹谷區10290中、包括面10284之一中央部分。脊狀部可為由與小凸塊相同或不同的材料製成。舉例來說,小凸塊和脊狀部可由同類型的彈性體製成;然用於脊狀部之彈性體可比用於小凸塊之彈性體硬。
脊狀部10294具有可變長度,其在使用期間提供可變軟組織接合程度。因此,較長和較短的脊狀部可協同作用隨著不同長度的脊狀部相繼接合於軟組織之部分而弄鬆並趕走碎屑。脊狀部10294從一緊鄰於面10284之寬底座區往一較窄末梢10696縮細。因此,會取決於使用者施加的力量提供加大的軟組織接合程度。
圖16示出一依據本發明之口腔保健用具的另一實
施例10810。口腔保健用具10810大體上包含與口腔保健用具10610相同的觀點和特徵,差別在於軟組織清潔器10880上之突出部的組態。軟組織清潔器10880異於軟組織清潔器10680之處在於其不包含脊狀部10294。因此,軟組織清潔器包含僅位在沿著面10284側部之小丘10288上的小凸塊10282。因此,經由位在小丘上之小凸塊提供溫和清潔作用。溫和清潔作用有利於口腔保健用具之同時功能性,譬如使用者經由軟組織清潔器10880清潔牙齒且同時接合臉頰內側軟組織的情況。溫和接合作用能在組織之溫和清潔效果之外提供令人愉快的感覺刺激。
圖17和18示出一依據本發明之口腔保健用具的另一實施例10910。口腔保健用具10910大體上包含與口腔保健用具10610相同的觀點和特徵,差別在於軟組織清潔器10980上之突出部的組態。軟組織清潔器10980異於軟組織清潔器10680之處在於脊狀部10994未被提供在面10284之中央部分內而是被提供在相鄰小丘10288對間之凹谷10290內。此外,脊狀部10994大致小於脊狀部10294。因此,會提供溫和清潔效果,此與口腔保健用具10810相似,在裝置之同時發揮功能期間有利。
今參照圖19-20,其示出一依據本發明之另一實施例的口腔保健用具12000。如圖所示,口腔保健用具12000包含一握把8103,一具有一框架12004之頭部
12002,位於該頭部之一前側上的底座或承窩12010、12020、12032、和12034,從該等承窩伸出的清潔元件12218,及一位於該頭部背對於該前側之一背側上的軟組織清潔器12280。口腔保健用具12000大體上包含圖10-13所示口腔保健用具10210的觀點和特徵,差異之處在下文說明。軟組織清潔器12280大體上與軟組織清潔器10280相同。然有多種軟組織清潔器組態可被使用,例如圖14-18之軟組織清潔器。
圖19和20所示口腔保健用具12000被例示為具有四個承窩:一近端承窩12010、一遠端承窩12020及二個中央承窩12032和12034。近端和遠端承窩從框架12004伸出,該框架係在頭部之一背部部分上。圖19和20所示實施例與圖1-18所示實施例的差異在於中央承窩12032和12034未直接連接至頭部12002之背部框架部分而是懸吊於近端承窩12010與遠端承窩12020之間。近端承窩和遠端承窩附接於框架,而中央承窩懸吊於框架上方。因此,中央承窩相隔於框架致使一間隙12050設置於其間。
中央承窩12032和12034經由橋接支撐件12060而懸吊,此等橋接支撐件可包括以一間隙12065分隔的一對大致平行支撐件12067。一第一橋接支撐件縱向地在近端承窩12010與中央承窩12034之間延伸,且第二對橋接支撐件縱向地在遠端承窩12020與中央承窩12034之間延伸。又,一橋接支撐件縱向地在中央承窩12032
與12034之間延伸。因而每一中央承窩被一對相對的橋接支撐件支撐。
儘管範例實施例顯示每一中央承窩之每一側上的成對支撐件12067,其他組態亦在設想之中。舉例來說,可取代一對支撐件12067而採用單一個橋接元件設置在近端或遠端承窩與相鄰中央承窩之間以及兩中央承窩之間。此種單一橋接件可較各成對支撐件12067之每一支撐件寬,致使該單一橋接件之寬度大致等於成對支撐件加上其間間隙12065之寬度。
中央承窩12032和12034大致具有高於近端和遠端承窩的自由度。在一組態中,橋接支撐件12060和12070為大致剛性的。即便如此,懸吊排列可向中央承窩提供適度的可撓性。在一較佳、更可撓的組態中,橋接支撐件12060和12070是許可從中央承窩12032和12034伸出之清潔元件之運動範圍遠大於從近端和遠端承窩12010和12020伸出之清潔元件(其通常是靜止或不可動的)之運動範圍的可撓特徵。此等可撓橋接支撐件可為由一彈性材料譬如熱塑性彈性體形成。亦可使用其他類橡膠材料,譬如其他熱塑性材料類,或是熱塑性聚氨基甲酸酯,或是塑性體(plastomer),或是以上之任何組合。
在一可撓組態中,橋接支撐件12060和12070是彈性的,並允許中央承窩在用具使用期間有向下力施加於該等中央承窩時以其支撐軸線為中心扭轉且/或朝框架
12004移動。又,橋接支撐件之彈性本質可許可中央承窩在該力減弱之時回到其原始形式或初始位置。再者,當口腔保健用具被以一平行於握把8103之方向移動時,中央承窩可隨其接合於一待清潔表面而縱向地偏轉。中央承窩在縱向方向中的偏轉亦可能是因為支撐橋接件12060和12070之彈性本質造成。此回復作用在移動方向的反方向內造成一有效運動,其因為引起額外刷洗行程而有助於清潔牙齒。
近端承窩12010與遠端承窩12020之間的距離可大於中央承窩12032和12034每一者之寬度,且在圖19所示實施例中約為該等中央承窩之一者的寬度的兩倍。又,在範例實施例中,中央承窩12032和12034被懸吊為離框架一段略小於中央承窩12032和12034之厚度的距離。支撐橋接件12060和12070之長度可明顯小於中央承窩12032和12034之長度,且在圖19和20所示組態中係約為中央承窩之長度的1/5。因此,在具備圖19和20所示組態之二個中央承窩的條件下,支撐橋接件12060和12070跨越遠端承窩12010與近端承窩12020間之總距離的25%以下。
又,圖19和20所示組態包括一形成近端承窩12010之一頂部部分、遠端承窩12020之頂部橋接支撐件12060和12070及中央承窩12032和12034的一體總成12500(參考符號未示於圖中)。一體總成12500可由一彈性體材料譬如軟質熱塑性彈性體(TPE)製成。同樣的,亦
可使用其他類橡膠材料,譬如其他熱塑性材料類,或是熱塑性聚氨基甲酸酯,或是塑性體,或是以上之任何組合。近端和遠端承窩之頂部部分12033和12035可附接於從底下頭部12002伸出之突出部(圖中未示),藉此向近端和遠端承窩12032和12034提供充分支撐效果及強度。該等頂部部分亦可被形成為隨同頭部框架之一體特徵,譬如從一體塑膠模形成。在被形成為差異化特徵之時,近端和遠端承窩可為由同於或異於框架、橋接支撐件及/或中央承窩的材料形成。舉例來說,橋接支撐件和中央承窩可為由一第一熱塑性材料製成,且近端和遠端承窩可為個別由一第二熱塑性材料譬如聚丙烯形成。在此一組態中,橋接支撐件及中央承窩可被製作成一體構造物,其被熔接或黏附於近端和遠端承窩。又,橋接支撐件、中央承窩、及近端和遠端承窩之頂部部分可被形成為附接於框架的一體構件。
如前文就圖7和8所示實施例所述,安裝在中央承窩上之清潔元件12218適於以自其可撓支撐組態獲益的多樣方式接合使用者牙齒、牙齦及其他表面。舉例來說,如圖19所示,中央承窩上的清潔元件可包括朝頭部之末梢端傾斜的前傾元件12090及朝握把端傾斜的後傾元件12092。這些前傾和後傾元件的位置及取向可提高此等元件會先於相應承窩上之其他清潔元件最早接合一待清潔表面的可能性,從而促使相應承窩在其上剩餘清潔元件接合該表面時屈曲。
如圖19更進一步顯示,清潔元件12218可包括直立壁12094,此等直立壁可如前所述為彈性體的或是以刷毛為基礎。此等直立壁除了清潔效果更提供有利的牙齒擦拭磨光效果。清潔元件12218亦可包含一中央柱狀清潔元件12270,其可包括一或多個用於透入口腔表面的刷毛。柱狀清潔元件可延伸超過同一承窩上與其相鄰的其他清潔元件,且其可具有一大致尖頭末梢。因此,中央清潔元件12270有效地透入並接合口腔表面及表面間隙。
清潔元件12218之末梢或終端可縮細,致使懸吊承窩在接合待清潔表面的同時分別被推往相鄰近端或遠端承窩12020和12010。故在使用期間,從中央承窩12032伸出的清潔元件可大致被偏往與從近端承窩12010伸出之清潔元件接合,而從中央承窩12034伸出的清潔元件可大致被偏往與從遠端承窩12020伸出之清潔元件接合。此偏動作用能與承窩因裝置移動中時傾斜清潔元件與清潔表面之接合而造成的移動一起發揮作用。懸吊中央承窩12032和12034之加大移動及屈曲更進一步增強該口腔保健用具的清潔有效性。
今參照圖21,其示出一與圖19和20所示實施例相似的牙刷13000且大致具有相同觀點和特徵,差別在於其中央承窩及清潔元件13218組態還有其缺乏軟組織清潔器。牙刷13000包含一握把8103及一具有固定式和懸吊式清潔元件之一組合的刷頭13002。刷頭13002包含
一框架13004、近端和遠端承窩13010和13020、及一懸吊於近端承窩與遠端承窩之間的單一中央承窩13050。握把8103、刷頭13002及近端和遠端承窩13010和13020可由一熱塑性材料譬如聚丙烯形成為一體構造物。
單一中央承窩13050具有一設置在該中央承窩之一中間部分中的彈性體區段13055。該彈性體區段較佳由一彈性材料譬如軟質熱塑性彈性體(TPE)製成,同時該中央承窩較佳由較硬材料譬如聚丙烯製成。中央承窩13050由一與近端和遠端承窩13010和13020連接形成橋接支撐件13060的模製TPE膜片13070固持於定位。膜片13070可形成一圍繞成對固定式近端和遠端承窩13010和13020且附接於中央承窩13050之對向兩側的環圈。近端和遠端承窩之側面部分以及中央承窩中的溝槽(圖中未示)可接收膜片13070。此外,膜片13070可經由一黏著劑及/或一熔體黏合附接於該等承窩。
膜片13070容許中央承窩13050在一清潔作業期間有充分力量施加之時朝框架13004移動。當此力施加於中央承窩時,中央承窩之對向半體13051和13053也會繞彈性體區段13055屈曲。因此,從中央承窩13050之任一端伸出的兩組清潔元件13218可互朝對方旋轉。中央承窩13050可在施加於該中央承窩上使其朝刷頭13002移動之力減小時屈曲回其原始位置。
從中央承窩13050伸出的清潔元件13218大致朝中心推拔,此係一大致相反於圖10和11及圖19和20所
示清潔元件之組態的取向。中心推拔促使清潔元件13218在使用者向牙刷13000施加適度力量抵住牙齒的同時穿入使用者牙齒之鄰接近端間空間。當使用者向牙刷施加過大力量時,中央承窩13050移動至與框架13004接觸並導致中央承窩繞彈性體區段13055彎曲且更進一步接合於清潔元件所施用的鄰接近端間空間。
今參照圖22A和22B,其示出一與圖21所示實施例相似的牙刷13010且大致具有與牙刷13000相同的觀點和特徵,差別在於其框架。如圖所示,框架13007包含一位於該框架之一中央部分且橫越其寬度的彈性樞紐元件13080。該樞紐元件可為由一TPE或是比框架其他部分更可撓之其他彈性材料形成。該樞紐元件亦可包含該框架之一減薄區域,一TPE或其他彈性材料圍繞此區域設置。舉例來說,框架之一近端部分13082及框架之一遠端部分13084可為由一較硬材料譬如聚丙烯材料形成,且可包含一設置於其間的細頸區域(圖中未示)。該頸部區域可能許可框架之近端和遠端部分相對於彼此旋轉。一彈性材料13081可包圍該頸部以抑制繞該頸部之旋轉。彈性材料可為經由一黏著劑結合、一熔體黏合或其他附接機構譬如圍繞該頸部之一壓縮配合而黏附於該框架。
樞紐元件13080許可框架13004之近端和遠端部分13082和13084在使用期間相對於彼此旋轉。因此,刷頭13010可大致沿一待清潔表面譬如圖22B所示使用者
牙齒捲曲或彎曲。又,樞紐元件13080可單純地提升刷頭之總體可撓性以適應各種清潔特徵、使用之取向、及外力。舉例來說,如圖22B所示,樞紐元件13080能許可框架13007屈曲如弓。在另一實例(圖中未示),樞紐元件13080能許可刷頭之末梢部分被往後屈曲,這會促使中央承窩13050因橋接支撐件被拉伸繃緊而背離框架移動。
今參照圖23A和23B,其示出一與圖21所示實施例相似的口腔保健用具13020且大致具有與牙刷13000相同的觀點和特徵,差別在於其中央承窩、清潔元件13218之排列、及一設置於頭部反向於前側之一後側上的軟組織清潔器13280的存在。軟組織清潔器13280與圖10-13及19-20之軟組織清潔器10280和12280大致相同。然有多種軟組織清潔器組態可用,譬如圖14-18之軟組織清潔器。牙刷13020包含一大致為一體且沒有牙刷13000彈性體區段13055的中央承窩13058。因此,該中央承窩可經由較剛硬中央承窩提供待清潔口腔特徵部之相對確實接合,同時保有經由其懸吊組態提供的好處。故中央承窩可藉由相對於框架往前、往後、往兩旁及/或往下移動來調適施加於頭部的清潔力。然其相對較大、剛性的大小可向附接於其之大量清潔元件13218提供一致取向。
從中央承窩伸出的清潔元件13218相似於牙刷12000的清潔元件12218且大致含有與圖19所示清潔元
件12218相同的組態、觀點及特徵。但由於中央承窩13058是橫跨與圖19牙刷12000之中央承窩12032和12034大約相同距離的單一承窩,中央承窩13058在其中央區域內包含額外的清潔元件。如圖23A所示,一中央柱狀清潔元件13096位於中央承窩之一中央部分,其相似於牙刷12000之柱狀清潔元件12270。柱狀清潔元件13096與柱狀清潔元件12270合作以有效地穿入並接合於口腔表面及表面間之間隙且在過大清潔力施加於清潔元件時將向下力傳遞給中央承窩。又,數個徑向清潔元件13098在中央承窩之一中央區域以一大致類輻條組態從中央柱狀清潔元件13096伸出。徑向清潔元件遍及承窩之一中央部分接合於待清潔特徵部,此等徑向清潔元件在中央承窩之側部提供一周圍結構。此周圍結構增進對於待清潔口腔特徵部之接合並可協助在使用期間使牙粉留在中央承窩之清潔元件內。
今參照圖24A和24B,其示出一與圖21所示實施例相似的牙刷14000且包含一握把8103及一具有固定式和懸吊式清潔元件之一組合的刷頭14002。刷頭14002包含一框架14004、具有清潔元件14018的近端和遠端承窩14010和14020、及一懸吊於近端承窩與遠端承窩之間的單一中央承窩14050。握把8103、刷頭14002及近端和遠端承窩14010和14020可由一熱塑性材料譬如聚丙烯形成為一體構造物。一軟組織清潔器14280與圖10-13及19-20之軟組織清潔器10280和12280大致相
同。然有多種軟組織清潔器組態可用,譬如圖14-18之軟組織清潔器。
中央承窩14050具有一設置在該中央承窩之一中間部分中、特定言之介於一對承窩片段之間的彈性體區段14055。該彈性體區段較佳由一彈性材料譬如軟質熱塑性彈性體(TPE)製成,同時該中央承窩較佳由較硬材料譬如聚丙烯製成。中央承窩14050由一與近端和遠端承窩14010和14020連接形成橋接支撐件14060的模製TPE膜片14070固持於定位。膜片14070可形成一圍繞成對固定式近端和遠端承窩14010和14020且附接於中央承窩14050之對向兩側的環圈。近端和遠端承窩之側面部分以及中央承窩中的溝槽(圖中未示)可接收膜片14070。此外,膜片14070舉例來說可經由一黏著劑及/或一熔體黏合附接於該等承窩。
中央承窩14050上的清潔元件14218相似於圖19和20所示清潔元件之組態,差別在於複數個從框架14004伸出並穿過中央承窩14050之一或多個開口(圖中未示)的中央可撓清潔元件14270。清潔元件14270更在其上表面上包括按摩及/或磨光元件14272。儘管圖中僅示二個清潔元件14270,應理解到可依需求僅使用一個或是使用二以上的清潔元件14270。清潔元件14270可附接於框架14004或是從刷頭14002反側上之軟組織清潔器14280延伸穿過框架14004。若為後者,則清潔元件14270可與軟組織清潔器14280同時模製。不管是
哪一種,一由膜片14070界定載有承窩14010、14020和14050的一體結構可從清潔元件14270上組裝至底座14004。其他建構方法亦在設想之中。
膜片14070允許中央承窩14050和清潔元件14218在一清潔作業期間有充分力量施加時受清潔元件14270引導朝框架14004移動。此移動提供前文未述的額外功能。此一功能是一在刷頭中間被固定式和可動清潔元件14018、14218圍繞的牙齒磨光器。又,清潔元件14270包含相對於刷頭14004處於一固定高度、但被在刷洗壓力下朝刷頭14004退縮之清潔元件14218圍繞的按摩及/或磨光元件14272,使得清潔元件14272在刷洗期間更為有效。
當刷洗壓力施加於中央承窩14050時,中央承窩14050之片段14051和14053以及清潔元件14270會繞彈性體區段14055屈曲。因此,從中央承窩14050之任一端伸出的清潔元件14218可互朝對方旋轉。中央承窩14050可在施加於該中央承窩上使其朝刷頭14002移動之力減小時屈曲回其原始位置。
今參照圖25A-25E,其示出一與圖23A和23B所示實施例相似的牙刷15000A-C且包含一握把8103及一具有固定式和懸吊式清潔元件之一組合的刷頭15002。刷頭15002包含一框架15004、具有清潔元件15018的近端和遠端承窩15010和15020、及一由承窩片段15051-15054界定(圖25A至25D之實施例)或承窩片
段15055至15058界定(圖25E之實施例)懸吊於近端承窩與遠端承窩之間的中央承窩15050。握把8103、刷頭15002及近端和遠端承窩15010和15020可由一熱塑性材料譬如聚丙烯形成為一體構造物。
中央承窩片段15051-15058由一與近端和遠端承窩15010和15020連接形成橋接支撐件15060的模製TPE膜片15070固持於定位。膜片15070可形成一圍繞成對固定式近端和遠端承窩15010和15020以及中央承窩片段15051-15058的環圈,該等承窩片段可由一沿著刷頭15002之縱向軸線(圖25A和25B之實施例)或橫向軸線(圖25C和25D之實施例)的可撓間隙15062分隔。另一選擇,圖25E之實施例的片段15055-15058可由一沿著刷頭之縱向和橫向軸線的可撓間隙15062分隔。承窩中的溝槽(圖中未示)可接收膜片15070。此外,膜片15070舉例來說可經由一黏著劑及/或一熔體黏合附接於該等承窩。
中央承窩片段上的清潔元件15218相似於圖23A和23B所示清潔元件之組態,差別在於一中央清潔元件15270沿其上表面具有穿過膜片15070中之一開口(圖中未示)的磨光脊狀部15272。此清潔元件15270相對於圖25A和25B之膜片15070及中央承窩片段15051、15053以一類似於圖24A和24B之清潔元件14270的方式作用。但由於中央承窩片段15051、15053沿刷頭15002之縱向軸線以一間隙15062分隔,此等片段會傾向於在
刷洗壓力下轉離突出清潔元件15270或是繞清潔元件15270旋轉,從而模擬鳥類翅膀之移動,導致效率及鄰接近端間之穿透力提高。一類似移動由圖24C和24D之片段15052、15054沿著橫向軸線經歷,且一更大規模的移動由圖25E之片段15055-15058沿著縱向和橫向軸線經歷。因此,清潔元件15270提供一中央樞紐,承窩片段15051-15058可繞此中央樞紐移動。
清潔元件15270可附接於框架15004或是從刷頭15002反側上之軟組織清潔器(圖中未示)延伸穿過框架15004。若為後者,則清潔元件15270可與軟組織清潔器同時模製。不管是哪一種,一由膜片15070界定載有承窩15010、15020和中央承窩15050片段15051-15058的一體結構可從清潔元件15270上組裝至底座15004。其他建構方法亦在設想之中。
今參照圖26和27,一牙刷16000包含一握把8103及一具有固定式和懸吊式清潔元件之一組合的刷頭16002。刷頭16002包含一框架16004、具有清潔元件16018之近端和遠端承窩16010和16020、及一懸吊於近端承窩與遠端承窩之間由承窩片段16051和16053界定的中央承窩16050。握把8103、刷頭16002及近端和遠端承窩16010和16020可由一熱塑性材料譬如聚丙烯形成為一體構造物。
中央承窩片段16051和16053由一橋接件16052分隔,該橋接件較佳為可撓且由與一模製TPE膜片16070
相同的材料形成,該膜片與近端和遠端承窩16010和16020連接形成橋接支撐件16060。膜片16070可形成一圍繞成對固定式近端和遠端承窩16010和16020及包含片段16051和16053之中央承窩16050的環圈,該等片段可沿刷頭16002之橫向軸線及/或如其他實施例所示(舉例來說參見圖25A-25E)沿縱向軸線以一可撓間隙16062分隔。承窩中之溝槽(圖中未示)可接收膜片16070。此外,舉例來說,膜片16070可經由一黏著劑及/或一熔體黏合附接於該等承窩。
近端和遠端承窩16010和16020可與刷頭框架16004為一體,致使膜片圍繞此等承窩之中央部分延伸,或者該等承窩可終結於膜片16070之邊緣(參見圖27之承窩16050之底部)且可藉由超音波熔接、黏著劑或類似方式附接於刷頭框架16004。因此,膜片16070可當作承窩16010、16020和16050上包含之清潔元件板之一外框架,該板可能可當作單一單元附接於刷頭框架16004。因此,承窩16010、16020和16050可當作單一單元組裝操縱,且可當作單一單元在刷頭框架16004之近端和遠端附接於刷頭框架16004。
圖27例示承窩16050之一部分、更特定言之為承窩部分16051的構造,其中清潔元件16018之底部16019經熔融形成一墊16021,該墊16021被困在一承窩外殼16053與底板16054之間。墊16021防止清潔元件16018通過承窩外殼16053中之刷毛束孔。底板16054舉例來
說可被黏著或熔接於外殼16053,其中底板16054至少局部被膜片16070包圍。因此,此實施例中之清潔元件16018被以一習知為免錨定集束(AFT)之方式固定在承窩外殼16053及底板16054內,但此等清潔元件並非如同固定在一刷毛束孔內之肘釘固定式刷毛束剛性地固定於任何特定支撐結構。
近端和遠端承窩16010和16020上的清潔元件16018可為利用如上所述之AFT程序得到支撐,其中清潔元件會被困在相應承窩外殼與刷頭框架之間,或者在承窩16010和16020構成刷頭框架16004之一體延長部的情況中該等清潔元件可被錨定於承窩16010和16020。若其是利用AFT程序提供,則承窩外殼與刷頭框架之間的連接會構成一邊緣連接,其中承窩外殼舉例來說沿著承窩外殼之外周熔接於刷頭框架以允許熔融刷毛末端的墊位在承窩外殼與刷頭框架之間。
當利用例如圖22A-22B所示具有一由數個區域組成之牙刷頭且所屬清潔元件(近端和遠端)與一可撓中央類橡膠場域互連的牙刷進行刷洗時,中央區可以一不受控方式下沈碰觸到下方刷頭框架(見圖22B)。因此,可能會有一噹啷聲響,亦即可撓場域之中央部分與清潔元件之一埋入塊體可能對結構或是對使用者造成傷害的顯著〝滑動/拉伸〞。藉由結合從刷頭向上突出的支撐件,可撓場域的移動可受控制意圖使該可撓場域相對於刷頭以一特定方式移動。
圖26和27例示一實例,其中單一中央突出部16270從刷頭16002背面上之一軟組織清潔器16280延伸到集束塊16050之底板16054上之一凹陷或缺口16055。此突出部16270較佳與一可撓材料之軟組織清潔器16280一起形成或一體模製,但並非必定如此,且為承窩16050提供一樞紐點。這讓承窩16050能夠相對於刷頭框架16004以一受控方式移動。視突出部16270之可撓性而定,承窩16050亦可為能夠法向移動或是朝刷頭框架16004移動(再次參見圖22B為例)。另一選擇,突出部16270可為剛性的且從刷頭框架16004伸出以提供一抗拒承窩16050朝向刷頭框架16004法向移動的剛性樞紐點。當然,儘管圖26和27例示單一個中央突出部16270,突出部或支撐件的數量和類型非侷限性來說可如圖28所示(在刷頭框架17004與中央承窩17050之間延伸的多個支撐件17270和17271)及圖29所示(沿著牙刷18000之中央承窩18050之橫向軸線從刷頭框架18004伸出的橫桿支撐件18270,與中央承窩18050發生直線接觸)變動。圖26-29之實施例每一者促成可撓承窩相對於刷頭框架之獨特移動,其中圖26-27所示結構促成至少一360度樞轉,圖28所示結構促成一較受限樞轉移動,且圖29所示結構促成突出部18270上之一搖晃移動。
由於可不脫離本發明之範圍就上述內容作出多種變化,希望將本申請案所含所有內容、包括以上所述所有機構及/或互動模式解釋為僅是範例說明且不以任何方
式限制隨附申請專利範圍項的範圍。此外,如前所述,希望依據本發明之口腔保健用具及相關方法可運用本申請案中提及之觀點、特徵和組態的各種組合。
