Benefits of technology

The angled cleaning element arrangement allows for better penetration into interproximal areas and retention of dentifrice, improving the cleaning process by directing and maintaining the dentifrice on the teeth, resulting in enhanced oral surface cleaning and reduced wastage.

Problems solved by technology

Additionally, such toothbrushes have a limited ability to retain dentifrice for cleaning the teeth.
Therefore, the efficiency of the cleaning process is reduced.

second embodiment

[0059]Referring now to FIGS. 9A-9B concurrently, a manual toothbrush 200 according to the present invention is illustrated. The toothbrush 200 is identical to the toothbrush 100 described above with respect to FIGS. 1-8 except that the central cleaning element 135 is omitted. In order to avoid redundancy, a further detailed description of the toothbrush 200 and its functioning is omitted with the understanding that the corresponding elements of toothbrush 200 are numbered the same as the toothbrush 100 except that they are in the “200 series.” The above discussion with respect to toothbrush 100 is thus applicable to the toothbrush 200.

third embodiment

[0060]Referring now to FIGS. 10A-10B concurrently, a manual toothbrush 300 according to the present invention is illustrated. The toothbrush 300 is identical to the toothbrush 100 described above with respect to FIGS. 1-8 except that the hollow cone structure 334 is formed by eight elongated cleaning elements rather than six. In order to avoid redundancy, a further detailed description of the toothbrush 300 and its functioning is omitted with the understanding that the corresponding elements of toothbrush 300 are numbered the same as the toothbrush 100 except that they are in the “300 series.” The above discussion with respect to toothbrush 100 is thus applicable to the toothbrush 300.

fourth embodiment

[0061]Referring now to FIGS. 11A-11B concurrently, a manual toothbrush 400 according to the present invention is illustrated. The toothbrush 400 is identical to the toothbrush 100 described above with respect to FIGS. 1-8 except that the hollow cone structure 434 is formed by ten elongated cleaning elements rather than six. In order to avoid redundancy, a further detailed description of the toothbrush 400 and its functioning is omitted with the understanding that the corresponding elements of toothbrush 400 are numbered the same as the toothbrush 100 except that they are in the “400 series.” The above discussion with respect to toothbrush 100 is thus applicable to the toothbrush 400.

Abstract

An oral care implement implementing a cleaning element arrangement having diverging cleaning elements. In one aspect, the invention is an oral care implement comprising a handle and a head. A plurality of cleaning elements extend from the first surface of the head so as to form a ring about an axis extending from the first surface of the head. Each of the cleaning elements extend from the first surface of the head at an inclined orientation so as to radially diverge from the axis. In one embodiment, a cleaning element wall also extends from the first surface of the head and circumferentially surrounds the plurality of cleaning elements. In another aspect, the invention may be an apparatus for incorporation into an ansate oral care implement that utilizes the aforementioned arrangement of cleaning elements.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 12 / 547,627, filed Aug. 26, 2009, the entirety of which is incorporated herein by reference.BACKGROUND[0002]A toothbrush is used to clean teeth by removing plaque and debris from the surfaces. Conventional toothbrushes are provided with a flat bristle trim that limit their ability to conform to the curvature of the teeth, to penetrate into the interproximal areas between the teeth, to sweep away the plaque and debris, and to clean along the gum line. Additionally, such toothbrushes have a limited ability to retain dentifrice for cleaning the teeth. During the brushing process, the dentifrice typically slips through the tufts of bristles and away from the contact between the bristles and the teeth. As a result, the dentifrice often is spread around the mouth, rather than being concentrated on the contact of the bristles with the teeth. Therefore, the efficiency of the cl...
