Abstract: A novel toothbrush staple for a holding a U-shaped tuft of bristles in a tuft hole of a toothbrush head. The staple is generally flat and its lower edge is rounded to inhibit rupturing the bristles at the bight portion of a U-shaped tuft of bristles mounted by the staple in the hole. The sides of the staple are provided with one or more horizontal grooves each having a sharp edge. The arrangement of tufts and staple is such that the rounded bottom of the staple contacts the bight portion of the tuft of bristles, thus precluding rupture due to sharp edges at the staple bottom bearing against the bight portion of the tufts, especially during initial installation of the tuft in the hole. Each leg of the U-shaped tuft is in contact with a respective staple surface. With the passage of time, plastic creep or flow results in the plastic on the inside wall of the hole flowing towards the staple sides and interlocking with the sharp edges of the grooves. Instead of an elongated groove having a sharp edge on each of the opposite major surfaces of the staple, these surfaces may be provided with knurlings. Further, the elongated grooves may intersect as well as being parallel, and may be of generally U-shape in transverse section.

Abstract translation: 一种新颖的牙刷钉，用于在牙刷头的簇绒毛孔中保持U形刷毛簇。 缝钉通常是平的，并且其下边缘是圆形的，以防止在由钉在孔中安装的U形刷毛簇的弯曲部分处的刷毛破裂。 订书钉的侧面设置有一个或多个每个具有尖锐边缘的水平凹槽。 毛簇和钉的布置使得订书钉的圆形底部接触刷毛束的弯曲部分，从而防止由于钉底部轴承处的尖锐边缘抵靠毛簇的弯曲部分而破裂，特别是在初始安装 孔中的簇绒。 U形毛束的每条腿与相应的钉表面接触。 随着时间的推移，塑料蠕变或流动导致孔的内壁上的塑料朝向缝钉侧流动并与凹槽的锋利边缘互锁。 代替在订书钉的每个相对的主表面上具有尖锐边缘的细长凹槽，这些表面可以设置有滚花。 此外，细长槽可以相交并且平行，并且在横截面中可以大致为U形。
