技术领域
本发明涉及带有舌头清洁器的口腔护理用具，所述舌头清洁器用于清洁舌头和嘴里的其它软组织。
背景技术
根据美国牙科协会，健康人中口臭通常归因于舌头上的微生物沉积物。由于其乳突的性质，舌头创造了独特的生态位置，其提供大的表面积，促进口腔细菌的积聚。残留在舌头上的厌氧细菌群和细菌可以导致慢性口臭的产生，通常称为口腔恶臭。
虽然在过去已经使用舌头刮擦器，但这些刮擦器不能充分地满足需要。过去的刮擦器通常是不舒适的，有伤害使用者的风险，且/或缺乏有效性。因此，需要带有舌头清洁器的口腔护理用具来提供舒适和安全的细菌和其它残渣的有效去除。
发明内容
本发明涉及带有舌头清洁器的口腔护理用具，所述口腔护理用具设置有硬和软材料的独特组合，以便以舒适和减少对使用者的伤害风险的方式有效地清洁舌头和嘴里的其它软组织。
在本发明的一方面，舌头清洁器由两个部件制成，该两个部件组合以限定从用具的头部延伸的至少一个清洁突起。舌头清洁器的一个部件由相对硬的材料构成，以提供稳定性和对软组织的有效清洁。另一部件由相对软的材料构成，以在用具使用期间提供对使用者的舒适性和安全性。
在本发明的一个示范性结构中，舌头清洁器包括由相对硬的材料组成的基体和至少部分地覆盖在基体上的软材料，该基体从头部的表面突出。硬基体提供良好的稳定性，以从舌头或其它软组织清洁细菌和残渣，而软层提供舒适性和降低的伤害风险。在一个实施例中，基体的末端覆盖有软材料。在另一实施例中，基体末端的小延伸部通过软材料而暴露出。
在另一示范性结构中，舌头清洁器包括由软材料制成的突起，该突起嵌入在用于提高刚度的硬基体中。在一个实施例中，突起是渐缩构件，带有用于接合并清洁嘴里的软组织的窄末端和锚定在头部的硬材料部分中的宽的基体部分。软材料舒适并安全地接合舌头。硬材料为清洁器提供提高的刚度和稳定性。
在本发明的另一方面，舌头清洁器由不同外形的两个部件制成。舌头清洁器的一个部件由相对硬的材料制成，而另一部件由相对软的材料制成。

具体实施方式
根据本发明的口腔护理用具以牙刷10(图1和2)形式图示和描述。然而，本发明可包含在其它口腔护理用具中，简单来说包括组织清洁用具。牙刷10包括头部12和柄部14。虽然图1仅图示柄部到头部的连接，柄部优选为由使用者抓握的细长构件。柄部14具有适于清洁使用者的牙齿和/或舌头所需要的操作的任何已知形状和结构。头部12包括一对相对的侧16、17，牙齿清洁元件20从侧16延伸且软组织清洁器21设置在侧17上。虽然该软组织清洁器21可用于冲击嘴里除了牙齿之外的区域，它主要用作舌头清洁器，为了方便将在本文中这样描述。虽然头部12显示为具有椭圆形形状，可以使用其它已知的形状。
牙齿清洁元件20可以为具有各种形状和尺寸的刚毛和/或弹性体构件。可以使用适于清洁使用者牙齿的元件20的任何形式或组合。
舌头清洁器21包括至少一个突起22，优选为包括多个突起，以清洁嘴里的舌头和其它软组织(例如，脸颊的内表面)。虽然突起优选在也设置有牙齿清洁元件20的头部上形成，突起可在其它用具或牙刷的其它部分上形成。对用具头部的任何引用简单地意味着插入嘴里的用具的可操作部分的引用，且并不涉及头部的具体形状、结构或位置。在本发明中，每个突起由硬和软材料的组合形成，以舒适和安全地提供对舌头(或其它软组织)进行优良清洁的有益效果。
在一个实施例中(图1和2)，多个突起22形成为延伸越过头部12的背侧17。每个突起包括从头部突出的基体部分28和覆盖在基体部分上的层29(图2)。基体28由相对刚性的材料制成，例如聚丙烯，但是可以使用其它许多材料。如图2所示，基体部分优选为形成头部的一部分，但可以单独地形成并通过粘合剂、紧固件或类似物附接到头部。层29优选为热塑性的弹性体，例如Santoprene、Thermolast-K、Dynaflex，但是也可以使用其它许多材料，只要它们适于口腔护理且足够软以提供希望的舒适性和/或安全益处。虽然突起22描述并显示为脊部24，如果希望，它们可以具有非脊形的结构(例如，柱形或圆锥形)。突起22的各种形状和截面构造都被考虑。
在这个结构中，基体28向窄末端32渐缩，以更好地插入舌头中的凹入并去除细菌和残渣。如图所示，基体可以形成为具有大致三角形截面，但是可以使用其它变窄的形状。此外，如果希望，以可以使用恒定截面形状、非渐缩形状或不向窄末端渐缩的形状。为了提高的舒适性和安全性，软上层29覆盖在头部12的整个背侧17上；即，尽管使用非常窄的末端来限定脊部24，层29保护使用者不切割或伤害其舌头或其它组织。软层29优选为在头部12的侧17上模制，但也可以例如通过粘合剂、紧固件等紧固。可替换地，软层或覆盖物29a可以形成为仅覆盖舌头清洁器21a的脊部24a的末端32a(图3)。当然，可以使用突起由上层29覆盖的其它变型。例如，软材料部件29可以比图3所示更多或更少地覆盖基体28，或可以覆盖基体28和头部12的侧17的仅一部分，而不覆盖整侧。在一个示例中，基体28从头部12的侧17延伸0.5到1mm，软材料部件29厚为0.3到0.5mm。然而，可以使用其它许多较小和较大的延伸范围和厚度来形成突起。
在另一实施例中(图4)，舌头清洁器21b包括至少一个由基体部分28b和上层29b限定的脊部24b。与前述实施例相同，基体28b由相对硬的材料制成，在优选结构中形成为头部的一体部分。与前述实施例相同，基体28b向窄末端32b渐缩，以有效地去除细菌和残渣，但是可以使用其它形状。上层29b由相对软的材料制成，其部分地覆盖基体部分28b。但是，在该结构中，剩下基体部分28b的末端32b未被覆盖，而基体的其它部分由软部件29b覆盖。然而，尽管末端32b是缩窄的，通过限制在软材料29b之外的暴露末端的延伸范围，通过暴露末端32b维持舒适性和安全性。更具体而言，当脊部接触并在其上移动时，舌头或嘴里的其它软组织趋于屈服或挠曲。该柔性使得短末端32b能够在舌头或其它软组织上通过而不伤害使用者。结果，保持了舒适性和安全性。
在该结构中，基体部分28b从在头部12b的侧17b中形成的凹入40向外突出。在该示例中，由于基体28b形成为细长的脊部，凹入40具有延伸越过侧17b的细长沟的形式。如果突起改为例如柱形，于是凹入优选为包围该突起。软部件29b填充并紧固在基体28附近的凹入40中，且限定外表面42，外表面42逐渐延伸到靠近末端32b的位置。在所示的示例中，上层29的外表面42具有宽阔弯曲的、凸的形状，舌头或其它组织抵靠该外表面42滑动。然而，只要外表面能够提供舌头或其它组织能够抵靠其滑动并暴露给下面基体28b的仅小部分的表面，该外表面可以具有许多不同的形状。在图4所示的该示例中，基体28b高为1mm(从凹入40的底部到末端32b)，且延伸到外表面42之外0.5mm，但是这些尺寸可以显著地变动。此外，结构可以变化。例如，凹入40可以取消且硬部件形成为直接从大致平面的背侧17延伸的较短的基体。在该结构中，软部件将优选为覆盖在头部背侧的至少一部分和基体的一部分上的大体均匀的层。同样，可替换地，相对硬的第一部件的末端部分可以紧固到相对软的第二部件(未示出)，而不是直接固定到头部。
在另一实施例中(图5)，舌头清洁器21c由限定突起48的软材料部件29c制成，软材料部件29c嵌入在相对硬的基体49中，优选为头12c的硬基体部分。在该结构中，突起48优选为从限定在头部12c的侧17c中的凹入50突出；但是凹入50可以省去。突起48优选为从凹入50向外延伸到由侧17c限定的平面55之外，使得突起48相对于侧17c高起以提供增加的清洁益处。然而，突起的末端56可以与平面55大致同范围，只要仍发生与软组织的接触。除了在该结构中凹入维持敞开之外，凹入50类似于上述的凹入40。在该示例中，由于突起形成为细长的脊部，凹入50为延伸越过头部的细长沟。脊部48锚定到头部中以提供较硬的部件(尽管为软材料)，从而提供舌头和其它组织的有效清洁。在所述的示例中，脊部48具有大约1mm(从凹入50的底部延伸)的高，且具有在背侧17c上大约0.5mm的突起。然而，可使用不同于这些尺寸的较宽范围的尺寸。
在该结构中，突起48包括嵌入在基体49(优选为头部12的一部分)中的锚定部分54和用于接触软组织的末端56。突起48优选为从锚定部分54到末端56渐缩，以限定用于有效地清洁舌头和其它组织的变窄的末端和用于更大支撑和刚度的宽阔的锚定部分。然而，可以使用其它渐缩和非渐缩突起。
此外，图5的结构图示了限定在侧17c内的凹部(即，凹入50)的一个示例，该凹部包括从其向外延伸的组织清洁凸部(即，突起48)。如上所述，凹部可以限定为细长的凹陷或脊形或半球形凹入，可以考虑其它的凹部。另外，凸部可以为任何形状和/或截面，包括但不限于在此披露的这些突起形状。例如，如图6所示，凸部可以为从方形轮廓的凹部62延伸的恒定截面的柱60。
在另一结构中(图7-9)，诸如牙刷70的口腔护理用具包括头部72、柄部74和沿头部72的背侧76布置的多个软组织清洁突起80。牙齿清洁元件(图7-9中未示出)在头部的相反侧上形成，如图1所示。虽然图7显示为多个不同曲率的弧形突起，应当理解的是，可以根据希望使用其它结构和构造。
在图8的实施例中，突起82、84、86和88与头部72整体形成且由与头部72相同的材料制成。头部材料优选为各由相对硬的材料制成，例如聚丙烯，但是可以使用其它材料。当然，虽然该突起显示为形成头部的一部分，该突起也可以单独形成且通过粘合剂、紧固件或类似物附接到头部。覆盖突起82和86、以及背侧76大部分的是优选为由比该硬材料更软的材料制成的层89。该层89留下突起84和88暴露在背侧76上。层89优选为模制在头部72的侧76上，但可以例如通过粘合剂、紧固件等紧固；且优选为从热塑性弹性体制成，例如Santoprene、Thermolast-K、Dynaflex，但是也可以使用其它许多材料，只要它们适于口腔护理且足够软以提供希望的舒适性和/或安全益处。虽然突起80描述并显示为脊形，如果希望，它们可以具有非脊形的结构(例如，柱形或圆锥形)，各种形状和截面构造都被考虑。
图8的实施例图示了具有第一材料的突起和第二材料的其它突起的多部件软组织清洁器。因而，使用者能够感觉并利用相对硬的突起部件和相对软的突起部件固有的不同功能性，以提供舌头和嘴里其它软组织的有效清洁。
在图9的实施例中，突起94和98由与头部72相同的材料制成且优选为也与头部72整体形成，而突起92和96由与头部材料不同的材料上层99制成。与图8的实施例相同，头部材料优选为各由相对刚性的材料制成，例如聚丙烯；而上层99优选为从较软的材料制成，例如热塑性弹性体，且模制到头部72上。虽然突起90具有不同的高度和截面，应当理解的是，可以根据希望使用不同或类似结构特征的各种构造。
虽然本发明的舌头或软组织清洁器主要结合横向跨过头部延伸的多个脊部讨论，本发明的构思可应用于可用作舌头或软组织清洁器的所有类型的突起。例如，脊部可以具有如2004年11月17日提交的美国申请10/989,267中公开的在头部上的所有类型的形状、尺寸、高度和构造，因此该申请作为参考引入。此外，突起可以形成为非脊形突起以及脊形和非脊形突起的混合，如美国申请10/989,267中或美国申请10/869,922中公开的。
同样，在以上披露的结构中可以进行各种其它改变，而不偏离本发明的范围。所有包含在本申请中的包括所有上述机构和/或相互作用模式的内容应当解释为是说明性的，而决不以任何方式限制所附权利要求的范围。
