Head for an oral care implement and a kit comprising such head

Abstract

A head for an oral care implement has an elongated mounting surface with an outer circumference, a longitudinal axis extending between a proximal end attached to, or repeatedly attachable to and detachable from a handle, and a distal end opposite the proximal end. The head comprises two outer rows of tufts extending from the mounting surface along the longitudinal axis in proximity to the outer circumference, and two inner rows of tufts extending from the mounting surface and being arranged between and substantially parallel to the outer rows. The tufts of the outer rows have a longitudinal extension and a cross-sectional area extending substantially perpendicular to the longitudinal extension. The cross-sectional area is elongated and has a longer axis and a shorter axis. The tufts of the outer rows are arranged in a manner that the longer axis defines an angle (alpha) of from about 20 degrees to about 65 degrees, preferably from about 30 degrees to about 50 degrees, more preferably about 45 degrees with respect to the longitudinal axis of the head. The tufts of the outer rows are inclined with respect to the mounting surface by an inclination angle (Beta) from about 65 degrees to about 80 degrees, preferably from about 70 degrees to about 80 degrees, further preferably from about 74 degrees to about 78 degrees, even further preferably from about 74 degrees to about 75 degrees, while the tufts of the inner rows are inclined with respect to the mounting surface by an inclination angle (gamma) from about 60 degrees to about 85 degrees, preferably from about 70 degrees to about 80 degrees, further preferably about 80 degrees.

Description

technical field [0001] The present disclosure relates to a head for an oral care implement and a kit comprising such a head and a handle. Background technique [0002] Oral care implements, such as manual toothbrushes and electric toothbrushes comprising a plurality of tufts of filaments, are well known in the art. Generally, the cluster is attached to a mounting surface of the head intended for insertion into the user's mouth. A handle is usually attached to the head, which handle is held by the user during brushing. The head is permanently connected to the handle or can be repeatedly attached and detached from the handle. [0003] Toothbrushes comprising a plurality of tufts are also known in the art, wherein at least two of the tufts are inclined in different directions relative to the mounting surface from which they extend. For example, toothbrush heads are known which have a head body and a plurality of tufts. The head body has a mounting surface and a plurality of...

Problems solved by technology

[0008] However, if used with one of the newly recommended brushing techniques, tuft assemblies as discussed above are less suitable for adequate plaque removal from gingival margins, interproximal areas, lingual surfaces, and other hard-to-reach oral areas and crumbs
