Abstract
A head for an oral care implement comprises a number of colored filaments of different types. The filaments extend from a mounting surface of the head and are grouped together to define an initial color pattern. At least two types of filament have staggered time-controlled color changing properties, wherein each of said type of filament changes its color within pre-defined time periods, the pre-defined time periods being different from each other so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern and over a subsequent second pre-defined period of time to a second color pattern, the second pattern being different from the first pattern.
Claims14
A head (10) for an oral care implement, the head (10) comprising a number of colored filaments of different types (12, 14, 18), the filaments (12, 14, 18) extending from a mounting surface (16) of the head (10) and being grouped together to define an initial color pattern (20),
- at least two types of filament (12, 14) having staggered time-controlled color changing properties,
- wherein each of said types of filament (12, 14) changes its color within a pre-defined time period, the pre-defined time periods being different from one another so that the initial color pattern (20) changes color characteristics over at least a first pre-defined period of time to a first color pattern (30), and over a subsequent second pre-defined period of time to a second color pattern (40), the second color pattern (40) being different from the first pattern (30),
- wherein a first type of filament (12) changes its color within the first period of time from an initial color to a second color to define the first color pattern (30), and
- a second type of filament (14) changes its color after the first period of time and within the second period of time from an initial color to a second color to define the second color pattern (40),
- wherein the second color of the first type of filament (12) is different from the second color of the second type of filament (14), and
- wherein the first period of time is different from the second period of time.
