Abstract
本发明涉及一种牙刷,其包括刷头和多个用于增强牙齿清洁的牙齿清洁器件。牙齿清洁器件包括清洁器件,其限定了径向阵列布置以用于牙膏更好地滞留。径向阵列可策略地安置于刷头上其它清洁器件内的离轴布置内。
Description
本申请为分案申请,原申请的申请号为200680032776.5(国际申请号为PCT/US2006/034518),国际申请日为2006年9月6日,发明名称为“牙刷”。
技术领域
本发明是关于具有改进的清洁刷头的牙刷及制造方法。
背景技术
牙刷用于通过从牙齿表面去除齿斑和残渣来清洁牙齿。常用的具有刷毛簇和复合轮轴设计的牙刷具有缺点。在刷牙过程中,牙膏沿着刷毛簇下滑且离开刷毛和牙齿之间的接触。结果,牙膏常常散布在嘴周围。因此,该清洁过程的效率大大降低。
复合轮轴设计的另一个缺点是在轮侧面上需要空间以安装轴。临近轴的区域必须是没有刷毛的,因为安装刷毛会妨碍轴运转。没有刷毛的刷头内侧的大区域大大降低了常用牙刷的清洁效率。而且,装配的轮轴设计具有多个要跟踪和装配的元件。上述元件的装配时间和跟踪在制造操作中可是昂贵的。
因此,需要有一种具有径向设计的牙刷,其提高清洁效率并且更有效地制造。
发明内容
本发明是关于一种具有径向取向的清洁器件的牙刷,以提供对使用者牙齿的增强清洁。
在一个实施方案中,牙刷包括具有一组牙齿清洁器件的刷头,该牙齿清洁器件通常限定了与刷头成为一体的径向阵列。在一种结构中,每个径向阵列通过多个独立的弹性清洁器件而形成,以保持使用者舒适和提供改进的牙齿清洁。
在一个实施方案中,牙刷包括具有流体保持部分的径向阵列,用于保持牙膏在牙刷上以强化清洁作用。
在一个实施方案中,清洁器件的径向阵列策略地与刷头纵向轴成一角度取向,以最大化刷毛运动的清洁效果以求整体改进的牙齿清洁,其包括牙齿之间的齿间区域,沿着牙龈线和牙齿的舌侧和正面侧表面。
在一个实施方案中,提供了一种制造牙刷刷头的制造方法。刷头基部在第一方向内模制,该第一方向可是垂直的,水平的或成一角度。在随后的操作中,至少一个径向阵列在牙刷刷头基部上模制。形成径向阵列的模的两个半部分在第二方向内移动,该第二方向与第一方向不同。

具体实施方式
牙刷100如图1-3A所示,具有把手103和刷头105,以及用于清洁使用者牙齿的牙齿清洁器件200。为使用者提供把手103以牢固地抓住和操纵牙刷100,把手103还可由多种不同的形状和多种结构形成。
牙齿清洁器件200可包括用于擦拭、清洁和/或按摩使用者口腔组织的长丝刷毛或弹性指状物或弹性墙。可使用本领域公知的其它结构的其它牙齿清洁器件。牙齿清洁器件可通过任何公知方式,例如通过免固定(anchor free)安装簇,而附加到刷头105的基板109。优选基板109分离地安装簇和形成,然后插入刷头内的插座。
刷头105具有径向牙齿清洁器件205(例如轮辐)的一个或多个径向阵列202,以最大化刷毛运动的清洁效果以求整体改进的牙齿清洁,其包括牙齿之间的齿间区域,沿着牙龈线和牙齿的舌侧和正面侧表面。径向牙齿清洁器件或轮辐205可具有任何形状和尺寸的固定横截面,或导致例如轮辐从较大横截面逐渐变细到轮辐末端处的较小横截面的可变横截面。每个轮辐还可具有远端的,自由端的横截面,其相对于轮辐纵轴形成角度以使轮辐在刷牙时承受向下弯曲或偏转。径向阵列202将沿着纵轴a-a的纵向刷牙运动转化为用于改进清洁的横向运动成分和纵向运动成分。在一种结构中,径向阵列202通过多个独立的弹性清洁轮辐205形成,以保持使用者舒适和提供改进的牙齿清洁。
如图2所示,在一个实施方案种,两个径向阵列202每个沿着纵轴a-a前后定位,径向阵列202的纵向轴b-b以角度ψ偏离纵轴a-a。在一个实施例中,角度ψ可在20到90度的范围内,或优选在45度。然而,其它角度是可行的。在可替换结构中,径向阵列202可以其它模式设置,包括非准直布置或离开纵轴a-a定位,例如在轴a-a的两侧之一。以这种方式,更多牙齿表面被清洁,更多量的牙膏也可保持在牙刷刷头105上。然而,在牙刷100上可提供多于两个阵列。
在一个实施方案中,通过保持通常会沿着轮辐冲洗的部分牙膏和影响保持住的牙膏流向径向牙齿清洁器件末端来完成增强清洁。如图4所示,径向阵列202包括固定的突出轴204和相邻轮辐205a-c之间缺口内具有的一系列连接段或流体保持部分206。如图5的部分截面视图所示,流动通道208由相邻轮辐205a-c的流体保持部分206和侧壁部分210限定。流体通道208的基部表面212通过流体保持部分206来形成。流体通道208的侧壁210通过相邻轮辐205a-c来形成。这个流体通道作为用于汇集刷牙期间刷头105上牙膏的接收池。
当流体保持部分206示于所有相邻轮辐之间时,可在较少数量的相邻轮辐之间提供流体保持部分。因此,想得到的清洁能力效率或量可通过牙刷制造商来控制。当流体保持部分的较低端示出模制于轴204时,流体保持部分可与轴断开连接或分离。轴204可构造为阻止径向阵列整体上沿其轴的运动,或者其可构造为允许径向阵列沿正交于径向轴的轴的运动。可替换地,轴204可构造为允许径向阵列相对于基板109在多个方向内摆动、旋转或弯曲。
在图2中,在一个实施方案中,轮辐205的末端从刷头105的刷毛区侧突出。轮辐的延伸侧布置在刷头105关于纵轴a-a的摆动运动期间提供了改进的齿间清洁和宽牙齿表面清洁。参考图3A,轮辐205比例如刷毛簇220的其它牙齿清洁器件更高于基板109地垂直延伸。这个构造还给使用者牙齿之间的齿间空间之间的轮辐205提供了更深的穿透。
在图3A中,每个刷毛簇220具有末端,该末端选择性地和优选地限定了斜切刷毛表面222,其向内与刷头105内部的径向阵列202成角度。通过实施例的方式,优选刷毛表面222与基板109成大约30度的角度Φ,但还可在10-50度的范围内。应该认识到其它角度值是可行的,且斜切可对于每个簇而改变。簇220的角度特性允许牙膏在刷牙操作期间在刷头105上保持更久,而不是被散布在嘴里。因此,该角度构造提供了牙膏在径向阵列202上定向汇集,以在牙刷刷头105的清扫或摆动运动期间增强清洁作用。
在图3B中,中心刷毛簇214具有相对于基板109的锐角β,其中末端限定了刷牙表面216,该表面将牙膏指向径向阵列202的方向内。在一个实施例中,该锐角可在10到89度的范围内。然而,其它角度是可行的。以这种方式,牙膏的增加部分保持在径向阵列上,以强化牙刷100的清洁作用。具有这种布置,从刷牙表面216提供的牙膏可保持在径向阵列202的流体保持部分206上,以用于更有效的牙齿清洁。中心刷毛簇214相对径向阵列202的会聚点的角度还产生了簇214填充进径向阵列202之间空间的外形。
图6说明了径向阵列400的可替换实施方案。至少一个安装柄脚(stem)或偏离构件403从基板109延伸到中心轴402。以这种方式,轴402垂直地与基板109隔开。柄脚403对于偏离侧面至侧面(side-to-side)运动是独立地弹性的或有弹回力的。该弹性布置使得轴402和轮辐405作为一个单元共同旋转。当然,轮辐405是可独立地弹性的或有点儿不易弯曲。弹性柄脚403和轮辐405的这种结构使得从牙刷的单一清扫产生复合刷牙运动。在另一个结构中,安装柄脚403包括限定非线性偏离构件403的线圈弹簧配件407,使得轮辐405的垂直下降(例如z方向压缩)影响轴402的旋转或转动运动。在这种非线性结构中,提供旋转中心409在基板109上方且偏置于构件403的垂直轴。
参考图7,牙刷100的背面(例如与径向阵列202相对)可选择地具有带有波浪形布置的组织清洗器300(参见图3)。组织清洗器300构造为具有多个组织接合器件302,该器件在优选结构中形成为小块(nubs),出于简明的目的下文中将其描述为“小块”。这里使用的“小块”通常是指包括从基部表面突出的柱状突起(没有对突起横截面形状的限制)。通常意义上,该小块在优选结构中具有比小块基部宽度更大的高度(在最长方向内测量)。然而,小块可包括其中宽度和高度粗略地相同或其中高度比基部宽度稍小的突起。而且,在某些条件下(例如小块到末端逐渐变细或包括基部缩小到更小突起),基部宽度可基本上大于高度。
当与舌头表面接合或者说摩擦,例如小块302提供与软组织的柔和接合。而且,优选小块302是柔软的以使其如需要的横向移动和清洁嘴里的组织表面而弯曲。在优选结构中,当使用中应用侧向压力时,小块302能从其各自的垂直轴弯曲和折曲。这种弯曲增强了软组织表面的舒适和清洁。
图8A和8B说明了与图1实施方案可替换的带有牙齿清洁器件200的牙刷500,550的实施方案。在图8A中,为了促进在牙刷刷头105背面的清洁作用,径向阵列502可构造为转动布置,以允许轮辐505的末端通过开口501突出。在转动布置中,提供柄脚用于轮辐在开口501内从侧面-侧面弯曲。在该布置中,在径向阵列502中产生的转动运动导致在牙刷刷头两侧的转动运动。在一个实施方案中,可在刷头105的背面上提供组织清洗器300并带有开口501。在一个实施方案中,以非转动布置提供径向阵列551。在图8B中,刷头105的相反侧可具有与径向阵列551分离的第二径向阵列552。径向阵列552的轮辐554从刷头105的基部向外延伸并穿过组织清洗器300。因此,轮辐554与小块302混杂。在这种结构中,第二径向阵列具有穿过刷头105延伸的外形,以匹配在刷头105另一侧的径向阵列551。
参考图9和10,优选径向阵列202在两个点焊模制(shot molding)操作中制造为与基板109合为一体。该操作消除了如刷头内具有轮或转动器件的常用牙刷中装配松散元件的需要。因此,模制工艺提供了有效的制造操作和能力,以产生允许更深地穿透牙齿之间的齿间空间的径向清洁器件。
基板109和径向阵列202的整体结构及相关的制造工艺的优势是消除了刷头105上的“刷毛缺失空间”。制造工艺实现了在阵列厚度的“阴影”下安装径向阵列,以允许刷毛簇被放置得极接近。在图9中,牙刷刷头105的基板109以模的两个半部分600在线性或非线性方向内移动来彼此对接的方式形成。在优选操作中,线性方向是垂直的。在模的两个半部分之间的空闲空间中应用模制材料。随后,模的两个半部分600分离以释放形成的基板109。模的两个半部分在可以是垂直的、水平的或成角度的方向内共同移动。在图10中,基板109是固定的,两个模的两个半部分602与基板平行地移动,以提供侧面模制(sidemolding)操作。该侧面模制操作在基板109上形成至少一个径向阵列202。形成径向阵列的模的两个半部分602在线性方向内移动,并具有多角度结构以同时形成多于一个成角度的阵列。因此,侧面模制方向可垂直于基板模制步骤的垂直方向。
在模制工艺中,基板109和径向阵列202可由相同或不同的材料制成。径向阵列202可依赖于特定期望的效果而以多种不同的聚合物模制。径向阵列206可具有大约13到35肖尔A(Shore A)的硬度值。非常薄的径向牙齿清洁器件可用半刚性材料模制,例如高硬度热塑弹性体(TPE),LLDPE,或其它基于PP/PE/聚酰胺的材料。更厚的结构可使用软些的材料,例如低到中硬度TPEs。在模制工艺后,通过免固定(anchor free)安装簇工艺在基板109上提供刷毛。然后装配好的基板109附加到形成牙刷刷头105背面部分的刷头插座。
该发明方面可实践于手动牙刷或电动牙刷,例如具有振动径向阵列的振动头。在操作中,之前描述的特征,独立地和/或以任何组合方式,改进了牙刷的清洁性能。这种独特的器件组合在小巧的刷头空间内产生了卓越的清洁效力。
