By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventors XI, Wen Jin (Shanghai, CN); GUO, Guang Sheng (Yangzhou, CN); DING, Xiang Ji (Yangzhou, CN), filed on September 3, 2014, was made available online on September 7, 2017, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.
This patent application is assigned to Colgate-palmolive Company.
The following quote was obtained by the news editors from the background information supplied by the inventors: "Tapered bristles with thinner bristle tips or tip regions are particularly known for efficacy in reaching the interproximal spaces in-between teeth, at the gingival margin and in the subgingival access. Traditional non-tapered bristles are generally known to be effective along wider tooth surfaces, such as the facial, buccal, lingual, and occlusal surfaces. What is needed is a more effective arrangement of bristles for efficient simultaneous cleaning of the tooth surfaces as well as the interproximal and gingival areas of the oral cavity."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "There is provided a toothbrush having a combination of tapered and non-tapered cleaning elements for enhanced cleaning effects. More specifically, in one embodiment there is provided a plurality of tapered bristle tufts of differing tuft configurations including a first tapered bristle tuft having a dome-shaped bristle tip profile situated toward one end of the head, a second tapered bristle tuft having an arcuate-shaped configuration situated toward an opposite end of the head, and a plurality of laterally-extending third tapered bristle tufts arranged in an alternating fashion with non-tapered bristle tufts and disposed between the first and second tapered bristle tufts. The tapered bristle tufts are preferably longer than the non-tapered bristle tufts to provide interdental penetration and more efficient and effective interdental and gingival cleaning. In one embodiment, the first tapered bristle tuft is preferably surrounded by a cup-shaped bristle tuft that covers and cleans the outer surfaces of a tooth. Additional non-tapered bristles are situated on the head to provide targeted cleaning of outer wider teeth surfaces.
"Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention."
