Abstract

一种牙刷具有一个狭长柄,在其一端设有从刷柄的一个表面上向外伸出的多丛鬃毛。刷柄是由半刚性的塑料制成的,在其与鬃毛表面反对的那个表面上设有一对突缘以便用来控制沿着柄长各点的曲率,有一较软材料的握持零件在刷柄含有突缘的那个部分上制出以便为使用者提供一个柔软的握持部。

Description

刷柄
本发明涉及刷柄,更具体点说涉及一种牙刷柄,其上有一能够被使用者的手指变形的手指握持部。
近来牙刷设计的特点是为牙刷柄提供各种握持的特性,企图让使用者产生更好的“感觉”,同时保持牙刷的结构性能以便将必要的压力提供给牙刷的鬃端。这些刷柄的外形设计多种多样,有在柄上开槽的或将柄制成其他形状的,刷柄除了整体结构外,还有由两部分构成的,其中一层薄而柔韧的材料被设置在柄的较为坚硬的部分上借以达到设计目的。但在许多构造中,往往只是将一薄层厚度在2mm以内的弹性材料形成在一坚硬的柄上,造成一个美观悦目的柄,对使用者却只有很少甚至没有人机学的使用价值。
在两部分的构造中,即将一个分开的较为柔韧的材料敷设到一个比较坚硬的柄件上时,通常需要兼顾各方面的要求,既要提供一定数量的柔软材料使使用者能用手指变形,又要保持刷柄的比较坚硬的刚度,同时还不能使刷柄不寻常地过厚。一个较厚的牙刷柄在很多情况下都是不能被使用者接受的,特别是当牙刷的供应对象是儿童或那些具有小手的人时。
在将柔软的手指握持材料结合到牙刷的握持部上时,还必须考虑到必须保持一个足够的刚性材料的结构,以便使使用者能将压力施加到牙刷的鬃部上,而不会使牙刷柄在使用一段时间后便发生损坏。因此需要提供一个由两部分构成的牙刷,其中整个刷柄长度的柔韧性是可以控制的,同时握持部保持一个合适的厚度以便使用者握持。
所以本发明的一个目的是要提供一个牙刷柄或其他类似用具,其握持部具有一个能被手指变形的部分以便使使用者得到美好的“感觉”。
本发明还有一个目的是要提供一种属于上述型式的构件,它在整个柄长上具有比现有技术的器件更厚的可被手指变形的材料。
本发明另一个目的是要提供一种上述型式的牙刷,它有一个可变形的手指握持部,同时在刷柄内保持着将一个合适的压力施加到牙刷鬃毛所必需的刚度。
本发明还有另一个目的是要提供一种物件如牙刷柄,它的设计简单,易于制造,同时保持上面列出的这些目标。
从下面的说明中可以看到,上述这些和其他一些目的都是可以达到的,为此而提供的牙刷具有一个狭长的柄,其上有一对相反对的表面,从靠近柄的一端的其中一个表面上向外伸出多丛鬃毛,而在柄的另一端附近设有一个握持装置,该握持装置具有一个沿着一部分狭长柄在另一个相反对的表面上形成的狭长凹坑,和至少一个最好为一对的从凹坑的两条边附近向外伸出并伸入到握持零件内的突缘,以便在刷牙时使狭长柄具有所需的刚度。
突缘一般被设置得完全进入到握持零件内,其内表面可以是凹坑内表面的延伸。突缘也可从狭长柄的外边向内偏置。
在凹坑的底面上可设有多个槽形的开口,这时握持零件将有多个部分伸入到槽形开口内。
虽然本发明在这里具体化为牙刷柄,但它可被引用到任何一种用具柄上,只要该用具柄具有一个狭长的体件,在其一端有一施加压力的表面,而在其另一端附近有一握持部即可。在这种用具的结构内,体件在与施加压力的表面反对的表面的轴向上沿握持部制有一个狭长凹坑,该凹坑在其两条长边附近一般设有一对向外突起的突缘。在凹坑内制有握持零件,这对突缘就突起到该零件内,以便在使用该用具时使刷柄的握持部具有所需的刚度。
就广义言,本发明可适用于任何牙科用具或类似物,只要其一端有一施加压力的表面,而在其另一端附近有一握持部即可。握持部一般具有一层柔软的热塑性弹性体,其在施加压力方向的厚度为2mm到15mm,肖氏A硬度值在5到30的范围内。
下面结合附图示出本发明的说明性的实施例,从中当可对本发明的创新的特点和优点有所了解,其中:
图1为在其上设有软握持部的典型的现有技术的牙刷的侧立视图;
图2为示出图1中现有技术的牙刷的细节的沿图1中Ⅱ-Ⅱ线切开的剖视图;
图3为按照本发明构造的牙刷的侧立视图,其反对侧的视图为其镜中图像;
图4为示出图3中牙刷的结构细节的顶视平面图;
图5为与图3类似的侧立视图,其中详细地示出图3和4的一部分结构;
图6为与图4类似的顶视平面图,其中示出图5中牙刷的一部分的另外一些细节;
图7为沿图5中Ⅶ-Ⅶ线切开的右剖视图,其中示出在该部分牙刷结构上制出的凹坑的细节;
图8为沿图5中Ⅷ-Ⅷ线切开的右剖视图,其中示出结构的另外一些细节;以及
图9为沿图5中Ⅸ-Ⅸ线切开的右剖视图,其中示出在图5到8中画出的那部分牙刷区域的细节。
现在参阅附图,特别是图1和2,其中示出一个典型的现有技术的牙刷90,该牙刷具有一个半硬性的柄件91,设在其一个表面上的鬃毛92,和设在与该表面相反对的另一表面上的握持层93。握持层93可由多种有供应的材料制成,其目的是要给使用者提供一个更为舒适的用手指握持的区域,并防止刷牙时柄在使用者手中的滑动。
如从图2可见,柄件91设有一对肩部94和95以便接纳并保持握持层93。从图2显然可知,在握持层93内的可变形的或柔韧的材料的数量必须足够使使用者的手指有柔软的感觉,同时所选材料还必须具有耐磨性,这对日常使用的可靠性是必需的。与此相反,柄件91必须具有足够的刚度和强度,以便将压力提供到鬃毛92上,同时在刷牙时柄在其整个长度上的变形应能被控制。当柄结构具有过分易变形的材料时握持区将太大使那些手小的人如儿童难予操纵,而当柄的刚性材料不够时,在必需提供适当压力的适当位置上将缺乏刚度。往往需要就每一个因素权衡以便获得所需的最佳结果。
现在参阅图3和4,本发明提供的牙刷10具有一个狭长的柄件12,其上有多丛鬃毛14从其下表面上向外伸出。在与此反对的表面上制有形式为握持零件16的握持装置,握持零件在其表面上制有多条槽以便提高零件的可握持性。柄件12一般由热塑性材料如聚丙烯制成,在本结构中它具有的肖氏R硬度值在97到100的范围内。握持零件16是用注射模塑法在柄件12上制成的,在本实施例中用的是一种热塑性弹性体材料,其肖氏A硬度值在5到30的范围内,最好为20,所选硬度值应在手指压力下有柔顺的感觉。在握持零件16和柄件12之间用化学粘结剂使两者粘合,在柄件12上有鬃毛14伸出的那个表面上还设有多条槽形开口18,并在注射模塑过程中使握持零件16的材料流动通过这些开口,这样既可更好地将握持零件16保持在柄件上,同时又可为使用者的手指提供另外的握持表面。在柄件12的与鬃毛14端反对的另一端上还设有一条狭长的开口20,如同槽形开口18那样,握持零件16的材料也被注射到槽形开口20内以便有助于将握持零件16的那个部分固定在柄件12上。
现在参阅图5到9,可见在柄件12上设有凹坑22,该凹坑22从柄件上一个与鬃毛位置反对的端头的附近延伸到超过柄件一半长度的一个点上。凹坑22在其两侧具有一对向上突起的突缘24和26,每一突缘的内表面都是凹坑22内表面的延伸部。突缘24和26从柄件12的外表面向内偏置,因此在将握持零件16的外表面制成柄件12的外侧表面的延伸部时,突缘24和26便完全被包含在握持零件16内。
从图7到9可以明显地看到,不论是牙刷柄的整体,还是柄件和握持零件,其大小都可按照本发明的目标制成。制成的牙刷既能满足刷柄大小应能容易操纵的需要,又能满足要有一定数量的柔顺材料来提供柔软握持零件16的需要,并且在柄件12的整个长度上需要变化的刚度能容易地加以控制,只要增加或减少突缘24和26的高度即可,其时在握持零件内的软材料的高度一般保持在2mm到15mm的范围内。另外,这个组合可在刷柄或用具的长度上的任一点完成,也就是说,可在刷柄长度上的任一点造成特定的刚度和柔软性,同时使牙刷保持一个美好的感觉和外观。
这样在图7、8或9的任一图中,如果需要有一刚度较大的部分,那么可以增加突缘24、26的高度。如果需要更多的柔韧性,那么可以降低突缘的高度。在握持零件16内材料的数量可以增减以便产生适当的感觉,而较坚硬的柄件可相应地增减以便维持所需的总厚度,在任一点上所需的总刚度可通过增加或减少突缘24、26的高度来获得。
