Description
本發明關於含有流體之毛細傳送系統之口腔保健用具。
口腔保健用具,尤其牙刷,通常係藉由施敷牙膏於刷毛區域,接著刷洗口腔部分(例如牙齒、舌頭及/或牙齦)而使用。某些牙刷具有流體貯存器及傳送輔助活性劑(例如潔白劑、呼吸清新劑及類似物)之系統。此中仍有提供用於傳送輔助活性劑之選擇的口腔保健用具之持續需求。
本發明關於具有毛細傳送系統之口腔保健用具。視情況,口腔保健用具包含具有潔牙元件於其第一表面之頭部。
於一具體例中,口腔保健用具包含含有至少一活性劑之貯存器。可施加各種活性劑,以提供治療、衛生及/或其他效益,例如清新呼吸、牙齒潔白、或產生熱、冷或疼痛感覺。
於另一具體例中,口腔保健用具包含毛細通道,係延伸通過至少一部分該用具,俾將活性劑傳送至一或更多出口。於一具體例中,出口係位於大體上相對於含有潔牙元件之第一表面之頭部的第二表面上。
於又另一具體例中,口腔保健用具包含具有潔牙元件之頭部、用於貯存含有至少一活性劑之貯存器以及溢流室。可
藉由隔板分開貯存器與溢流室。由纖維質材料、陶瓷、多孔性塑料或其組合所構成之毛細通道延伸通過至少一部分該用具,俾將該活性劑從該貯存器傳送至一或更多出口。
於另一具體例中,口腔保健用具包含具有潔牙元件之頭部、用於貯存含有至少一活性劑之貯存器、延伸通過至少一部分該用具以將活性劑傳送至一或更多出口之毛細通道以及運動產生裝置。當驅動時,運動產生裝置振動用具或其一部分,例如頭部。振動增強潔牙元件的功能,並且亦促進傳送活性劑通過毛細通道(一起提供增強的清潔作用)。
圖1示意地顯示一牙刷,其具有把手1及含有一或更多潔牙元件(例如刷毛6及/或彈性體清潔元件7)之頭部2。貯存器11係用於貯存含有活性劑之介質。介質最常呈液體形式,但可呈其他形式,例如半固體、糊漿或凝膠。貯存器11可包含貯液槽11a,係與傳送區11b相連。毛細通道14通常於牙刷的長度方向延伸,俾將活性劑從貯存器11傳送至至少一出口15。
根據一態樣,出口15可位於相對於含有潔牙元件和7之表面之頭部2的表面上。根據另一態樣,出口15可位於刷毛6及/或彈性體清潔元件7內。視情況,複數出口可設於含有潔牙元件之頭部表面以及該頭部表面之相對表面兩者,例如用於從相同的來源傳送相同的活性劑或從分開的來源傳送不同的活性劑。
通道14使用毛細作用將液體從貯存器11取至出口15。出口15可建構為非織造墊、薄膜或其他容許含有活性劑之介質通過之結構。可用於出口之材料的實例包含多孔性塑料及其他多孔性材料,例如以下針對毛細通道14所描述者。
毛細通道14通常具有毛細結構,並且通常是多孔性材料。適合的材料的實例包含纖維質材料、陶瓷、多孔性塑料,例如售自Porex Technologies,Atlanta,Georgia者。纖維質材料的實例為經確認類型標號C10010之丙烯酸系材料(係售自日本東京,Teibow Hanbai Co.,Ltd.)。可提供具有較大和較小毛細分布之多孔性及/或纖維質材料的混合物。通道可由若干彼此連接或成為較大單一毛細管路之小毛細管路所形成。
貯存器11可由任一種適合的材料形成,並且可包含範圍為從親水性至疏水性之網狀發泡體(reticulated foam)。疏水性發泡體可用於非水性基底液體。網狀發泡體的實例為Recticel(比利時,Wetteren)製造之Bulpren S90。Bulpren S90為一種以每英吋平均90個孔隙之聚酯為基底之開孔型胺基甲酸酯發泡體(open cell polyurethane foam)。可用於貯存器11之材料的實例包含陶瓷及多孔性塑料。
可用的毛細架構的非限定實施例係顯示於圖4-7中。毛細裝置10通常具有容納用於貯存液體13之貯存器11與溢流室25之殼體20。貯存器11與溢流室25可以例如隔板21分開,否則可以例如以下圖7所述方式分開。貯存器11可為殼體20之組成部件或連接於殼體之分離元件。入口22容許空氣自由地進出溢流室25。
隔板21可包含被毛細通道14閉合之開口12。通道14通常從開口12延伸至出口15,並且與毛細貯存器16直接接觸。毛細貯存器16的平均毛細管通常小於平均毛細通道14。雖然毛細貯存器16係位於約毛細通道14的周圍,但其不需完全地延伸於通到周圍。嚴格分開毛細貯存器16與毛細通道14是不必要的。
毛細通道14可緊配把手1中之開口,或另外地,把手1可過模塑於毛細通道14周圍。毛細通道14通常提供空氣可另外進入閉合的貯存器11之唯一路徑。通道14較細的毛細管將流體轉移至出口15。較大的毛細管使空氣進入貯存器11。一般而言,空氣可通過至少最大的毛細管進入通道中。
請參照圖5,透過實例,當空氣膨脹現象出現於貯存器11內部時,貯存器11中之部分流體13將通過開口12及通道14轉移進入毛細貯存器16之正常無流體的部分。換言之,毛細貯存器16接收過量的流體,並且防止從出口15或用具的其他部分之未受控的流體洩露。當貯存器11中之壓力下降時,於毛細貯存器16中之過量的流體將通過通道返回貯存器11。只要當溫度變動例如造成貯存器11中之空氣體積變動時,則重複此程序。由於貯存於毛細貯存器16中之流體總是返回貯存器11,故當有空氣膨脹現象時,毛細貯存器將不會填充至容量。再者,即使通道14持續地被至少在開口12範圍中之流體潤濕,但空氣無法中斷流體13返回貯存器11,只要有流體在比通道14的最大孔隙更大的貯存器16之毛細管中即可。
雖然出口15係以與通道14分離的元件顯示於圖1、3、5及6中,但應理解可另外地設計出口15與通道一體成形,如圖4和7所示。當出口15由多孔性材料形成時,其孔隙通常應小於通道14的孔隙,以便確保通道14中的流體將於分散過程中流向出口15。請參照圖4和6,可建構通道14,使得其延伸通過接近貯存器底座18之區域19。在此類型架構下,毛細貯存器16和毛細通道14通常被管件24包圍。管件24提供防止不想要的洩漏現象之額外保護。
於圖4所示之架構中,毛細貯存器16和毛細通道14為分開的結構元件,並且通道14延伸進入底座區19。於圖6所示之架構中,具有必須的毛細管尺寸組合之多孔性材料的混合物形成單一毛細貯存器16和通道14。
於圖5所示之架構中,通道14和毛細貯存器16定義出類似圖6所示之單一結構元件。整合的通道和毛細貯存器的背部140逐漸變尖,使得其可容納於開口12中。為了確保開口12有足夠量的細流體轉移毛細管量,可依界定方式在開口處將此部分的組合通道/貯存器夾在一起。背部140亦可提供為連接於毛細貯存器之分離元件。
如例如圖7所示,可建構毛細通道14’,使得其包含使貯存器11與溢流室25分開之徑向延伸部。通道14’和徑向延伸部填滿介於貯存器11與溢流室25間之開口。於徑向延伸部中之孔隙可實質上與通道14’中者相同,並且容許空氣通過,但阻止流體流動。因此,徑向延伸部可用於調節空氣流入通道14’中。
此種通常類型的毛細流體系統的實例係顯示於例如美國專利第5,102,251、5,352,052、6,089,776、6,095,707、6,164,858、6,183,155、6,322,268及6,497,527號中,所揭示者係合併於本案以供參考。
根據另一態樣,可提供振動裝置以振動牙刷或其一部分,例如頭部2或其一部分。可使用振動產生裝置來振動潔牙元件6和7及/或軟組織清潔元件,同時促進活性劑通過毛細通道14傳送,俾提供增強的清潔作用。
可使用廣泛類型的振動裝置於廣泛頻率範圍內產生振動,以符合特殊應用之目的。許多類型的振動裝置是市面上有售的,例如換能器。振動裝置之一實例提供頻率範圍為約100至350 kHz。振動頻率可具有不同波形,包含正弦波、方波、鋸齒狀等等。然而,其他數值和波形是可能的。振動裝置可位於牙刷頭部或其頸部。當驅動時,振動裝置受到電池的動力(並且受到電路板或轉換系統中之電子元件控制),進而在牙刷的頭部中引起振動,因而增強由潔牙元件所提供的潔牙作用。在另一具體例中,振動裝置可包含連接於一軸(shaft)之微馬達,其中該軸係連接於相對於牙刷縱向軸平行之一軸偏心轉動。於又其他具體例中,振動產生裝置包含依照平移方式由微馬達驅動之偏心元件。
開關(例如按鈕、肘節開關、轉盤或類似物)可用於觸發振動裝置。振動裝置經常有一電源,如電池。觸發開關可造成振動產生裝置操作一段使用者界定的間隔(例如於壓下按鈕或開關處於嚙合位置之時間),或者可觸發造成振動裝置操
作一段預定時間之定時電路。倘若使用定時電路,則可重新設定相關的間隔或者可藉由使用者觸發的轉盤調整。
本發明之另外的具體例包含振動裝置、刷毛(或其他潔牙元件)及其他在美國專利申請案序號第10/768,363號(2004年1月30日申請,並且標題為”具有增強的清潔效果之牙刷”,以美國專利公開案第20050091769A1號公開,係合併於此中以供參考)的結構。舉例來說,牙刷的頸部可具有由彈性上相當具順應性的材料製成之頸部區,俾提高頸部區的彈性。這將容許頭部在牙刷使用過程中,於力量作用於牙刷表面方向之情形中可彈性地被迫返回。視情況,頸部區可設計為延伸通過部分頸部周圍之缺口,並且填充具彈性順應性的材料(例如熱塑性彈性體)。
出口15可結合於彈性體材料,以提供組織清潔器,此可用於例如清潔舌部、臉頰、嘴唇及/或牙齦。組織清潔器可使用多種適合的生物可相容彈性材料,例如彈性體材料。為了提供最佳的舒適性以及清潔效益,彈性材料通常具有硬度性質在A8至A25 Shore硬度之範圍內,例如市售自GLS Corporation之苯乙烯-乙烯/丁烯-苯乙烯嵌段共聚物(SEBS)。
可建構具有複數組織卡合元件(可形成為結節)之組織清潔器。此中所用的”結節”一詞通常代表涵括從底座表面直立之柱狀突起(不限於突起的斷面形狀)。一般而言,結節可具有大於結節底部寬度(於最長方向測得)之高度。結節亦可包含其中寬度和高度大致相同或其中高度稍微小於底部寬度之突起。
此等組織卡合元件可有助於降低不良呼吸的主要來源並且改善衛生。結節使得得以移走來自舌部和口部內其他軟質組織表面之微植物群及其他碎片。舌部特別地易發展出已知居住可能貢獻不良呼吸之有機物及碎片之細菌層。此微植物群可見於大部分舌上表面上之乳突間的凹槽,以及口中的其他軟質組織。當嚙合或拉住舌表面時,舉例來說,彈性體組織清潔器的結節可提供溫和卡合軟質組織,同時向下達到舌部相鄰乳突的的凹槽中。組織清潔器的彈性體結構亦使得底部表面跟隨著口部組織表面的自然輪廓,例如使用者的舌部、臉頰、嘴唇及牙齦。此外,軟質結節必要時可撓曲,以便來回移動及清潔沿著所移動之口中的軟質組織表面。
結節通常呈圓錐形,例如呈真正圓錐形、截頭錐形元件,並且其他漸縮為窄端部之形狀及因而類似錐形之形狀(無論是否於其漸縮端是均勻、連續的或具有圓形斷面)。頂部較小的寬度或直徑以及圓錐形結節的長度使得結節掃入舌部的凹槽和其他表面中,進而清潔微生物沉積物和其他來自軟質組織表面之碎片。當使用期間施加側壓時,結節亦可從其個別的垂直軸撓曲和彎曲。此撓曲促進軟質組織表面之舒適度和清潔。另外,組織清潔元件可具有其他形狀。就一時施例而言,組織清潔器可具有不同形式,例如揭示於共同申請中的美國專利申請案序號第11/566,479號(2006年12月4日申請),其係合併於本案以供參考。
於製造牙刷之過程中,含有活性劑之媒介可合併於密封的貯存器11,在此情況下,可於耗盡活性劑供應之後拋棄牙
刷。另外,可通過入口(未顯示)重新填充貯存器11,及/或可藉由插入可更新的藥筒於牙刷中的凹槽中而更新貯存器11。藥筒可於插入之後經彈簧負載而停留於適當位置,並且可具有密封墊以防止不想要的活性劑洩漏。
如圖1所示,牙刷可包含彼此相連(例如藉由螺紋卡合、卡扣及類似方法)的刷子區A及貯存器區B。貯存器區B可為用完即丟的、可再填充的及/或可與其他例如含有不同活性劑之貯存器區B交換的。
視情況,使用者觸發的開關,例如撥號盤(未顯示),可具有複數供選擇若干活性劑之一或若干種之設定。舉例來說,撥號盤可具有關於氧化劑/潔白處理之第一設定、關於呼吸清新處理之第二設定以及關於抗菌處理之第三設定。可以含有牙刷或其刷子區A之套組以及含有活性劑之一或多種藥筒或貯存器區B之形式供應牙刷。複數藥筒可用於例如供應不同的活性劑或替代供應相同的活性劑。
圖1係示意地顯示具有頭部2、刷毛6及把手1之牙刷。應瞭解可使用任一種刷毛結構及任一種把手結構,並且本發明應不視為任一特殊結構之限制。
藉由使用刷毛6及/或其他潔牙元件刷洗牙齒或牙齦,及/或藉由組織清潔器按摩舌頭、牙齦或口腔的其他區域而利用此牙刷。可通過存在於潔牙元件之中或附近及/或組織清潔器之內及/或牙刷上的其他位置上之一或多個出口,施加活性劑。視所用的活性劑類型以及出口的位置而定,可於刷洗之前、期間或之後施加活性劑。
可用的活性劑之非限定實例包含抗菌劑、潔白劑、抗過敏劑、抗發炎劑、抗黏劑、牙斑顯示劑、調味料、可感覺成分及著色劑。此等藥劑的實例包含金屬離子藥劑(例如亞錫離子藥劑、銅離子藥劑、鋅離子藥劑、銀離子藥劑)、三氯生(triclosan)、三氯生單磷酸鹽、氯己啶(chlorhexidine)、阿立西啶(alexidine)、海克替啶(hexetidine)、血根鹼(sanguinarine)、氯化苄烷銨;水楊酸苯胺、度米芬(domiphen bromide)、氯化十六基吡錠、氯化十四基吡錠、氯化N-十四基-4-乙基吡錠(TDEPC)、奧替尼啶(octenidine)、德摩哌醇(delmopinol)、辛哌醇(octapinol)、乳酸鏈球菌素(nisin)、必須油脂、呋喃酮、細菌素、黃烷、類黃酮、葉酸、維生素、過氧化氫、過氧化脲、過碳酸鈉、PVP-H2
O2
、聚合物結合的過氧化物、硝酸鉀、咬合劑、生物活性劑、精胺酸鹽類、精胺酸碳酸氫鹽、巴茶林(bachalin)、多酚類、丙酮酸乙酯、胍基乙基二硫、牙垢控制劑、防污成分、磷酸鹽、聚乙烯基膦酸、PVM/MA共聚物、酵素、葡萄糖氧化酶、木瓜蛋白酶、無花果蛋白酶、月桂醯精胺酸乙酯、薄菏腦、香芹酮、茴香腦、許多調味醛類、酯類及醇類、綠薄荷油、薄荷油、冬青油、黃樟油、丁香油、鼠尾草油、桉樹油、墨角蘭油、肉桂油、檸檬油、酸橙油、葡萄柚油及/或柳橙油。
可選擇活性劑及/或其媒介以補充牙膏配方,例如藉由調和調味料、著色劑、美容成分或活性成分。可施加調味料,以於刷洗期間產生逐漸的風味變化(這對於單獨使用牙膏而言目前是不可能的)。
活性劑可與牙膏相容,或可能的不安定的及/或可與典型牙膏成分產生反應。活性劑亦可為用於促進整體刷洗功效之潔牙劑。
活性劑可提供於任一種適合的賦形劑中,例如為水溶液或呈凝膠或糊漿形式。賦形劑的非限定實例包含水、一元醇(例如乙醇)、聚(氧化乙烯)(例如聚乙二醇,例如售自Union Carbide之PEG 2M、5M、7M、14M、23M、45M及90M)、羧基亞甲基聚合物(例如售自B.F.Goodrich之Carbopol934及974)以及其組合。視諸如活性劑性質及介質所需的性質(例如黏度)等因素而定,適合的賦形劑之選擇係為熟習本技藝之人士可明白。牙齒潔白組成物係揭示於美國專利第6,770,266及6,669,930號,所揭示者係合併於本案以供參考。
貯存器11可含有欲用於單次使用或少次適用之適量的活性劑媒介,或可促進延長期間之重複使用,例如達到若干月或若干年。貯存器11的尺寸可經選擇為可與所需的牙刷總尺度以及諸如活性劑的安定性和每一施藥期間所施加的媒介用量等因素相容者。
貯存器11中供應之活性劑通常不含或實質上不含與活性劑及/或含活性劑之媒介不相容的成分,例如前述之不相容的牙刷成分。
牙刷視情況可具有隔間及/或容許接觸許多部件之進入面板(access panels),例如電源及貯存器。電源可為例如熟知之可更新或可充電的電池。
圖8-13顯示一種口腔保健用具,例如牙刷100,其係具
有把手103及可用於清潔牙齒和口中的軟質組織(例如舌部、臉頰的內部表面、嘴唇或牙齦)之頭部105。把手103係提供給使用者容易握持和操縱牙刷,並且可由許多不同的形狀和結構形成。雖然頭部相對於頸部通常變寬,但在某些結構中,其可為手把之連續延伸或窄化。頭部105可具有支持潔牙元件107之第一面106(圖12和13)以及支持組織清潔器300之第二面108(圖9和10),其可具有一或多個用於分配如上述的活性劑之出口。第一和第二面106、108可位於頭部105的相對側。然而,組織清潔器300可安裝於例如把手103的最近端104。組織清潔器300或其一部分亦可位於頭部105的周圍側面101上或如所示進一步朝把手103的最近端104延伸。
組織清潔器300可具有複數組織卡合元件303(圖8-12),其可形成為結節。
如圖9和11所示,結節303可為圓錐形的。請參照圖11,每一圓錐形組織卡合元件303的底部305可大於對應的頂部307。在圓錐形結構中,底部305具有較寬的截面積,以提供有效的剪切強度,進而禁得起組織清潔器300沿著舌部表面或其他軟質組織表面進行側向移動。
如圖10所示,結節303可於大體上平行縱軸a-a之方向,以縱列排列。再者,結節303係以橫列R1、R2排列於平行底面301之軸上,並且大體上垂直於縱軸a-a。相鄰的結節303可以交錯排列方式提供於底面301上。例如,相鄰橫向列之結節R1和R2可有非直接在彼此後方的結節303。
此中所稱之第一結節係指當其位於在縱長方向延伸的第二結節側向範圍內時,在第二結節的”正後方”。此結構使得藉由促進微植物群及其他碎片之移除(尤其從舌部相鄰乳突的凹部)可提供改良清潔軟質組織表面。然而,結節可無規地或以各式不同的圖案排列。
雖然可使用其他製造方法,但可藉由模塑於頭部105而形成舌部清潔器300。請參照圖8和11,組織清潔器300可模塑於頭部105表面108中之凹坑或接收槽111。接收槽111可具有較低底面113以及遠離較低底面113延伸之周圍側壁115。於一安裝架構中,可露出組織清潔器300的結節303以供使用,其中組織清潔器300的底面可相對於頭部表面114平齊或凹入。然而,其他方位是可能的。再者,組織清潔器的底面301可嵌入頭部105中或受到具有結節303突出適當開口之另一層體覆蓋。
由圖8和11可發現,表面108亦可包含一或多個位於凹坑111內之釘樁構件(peg members)117a-c。釘樁構件117a-c形成對抗相對模具之錨定點,以避免頭部在注射模塑之壓力作用下移動。因此,組織清潔器300可包含一或多個互補孔311a-c,以露出釘樁構件117a-c的頂部。雖然釘樁係以沿著頭部中線(例如縱軸a-a)之排列方式顯示,但釘樁可具有許多不同的位置。再者,釘樁和凹坑二者可涵括於頭部105,但任一者可不需伴隨另一者使用。
另外,凹坑111及釘樁構件117a-c可用於定位及固定先前模塑的組織清潔器,雖然此等結構不須使用此一先前模塑
的組織清潔器。
釘樁構件117a-c可具有多種形狀和長度。請再參照圖8和11,頭部105具有遠離凹坑111的較低底面113延伸至周圍側壁115的高度之釘樁構件117a-c。釘樁構件117a-c係呈圓柱體形式,但其他形狀和長度之釘樁構件117a-c是可能的。雖然可使用模塑方法將組織清潔劑結合於頭部,但可藉由黏附劑或其他已知手段進行和連接組織清潔器。
從圖8-11可發現,組織清潔器300可形成為由軟質和柔軟的彈性體材料構成之墊片,以便可舒適清潔和有效移除沉積於舌部表面上之細菌和碎片、口中或甚至沿著嘴唇的其他軟質組織,以及用於分配上述的活性劑。組織清潔器300亦可提供有效按摩、刺激以及從舌部、臉頰、牙齦或嘴唇移除細菌、碎片及上皮細胞。
請參照圖12和13,頭部105的潔牙元件107可包含多種可用於擦淨、清潔和按摩使用者的牙齒和牙齦之潔牙元件。可使用任一種適合形式的潔牙元件。”潔牙元件”係以廣義使用,代表細絲刷毛或彈性體指狀物或具有任一種所需形狀之牆狀物。如圖12之實施例所示,潔牙元件107包含末梢潔牙元件203a-b(位於頭部105的末端121)、周邊潔牙元件205a-l、縱向潔牙元件207a-c(沿著縱軸a-a排列)、拱形潔牙元件209a-d及211a-b以及近端潔牙元件213a-b。潔牙元件205、207、211及213可提供為成簇的刷毛,而潔牙元件209可形成為彈性體牆狀物。然而,可使用其他形式和類型之潔牙元件。
應瞭解雖然本發明參照其特殊具體例闡釋,但以上說明及實施例僅為說明之用,而非用於限制本發明之範圍。本發明之其他態樣、優點和變化,熟悉本技藝之人士審視本發明時當可明白,並且此等態樣和變化係在本發明之範圍內,並且在本發明之說明和申請專利範圍之內。
