Abstract
A head for an oral-care implement comprises a number of colored filaments extending from a mounting surface of the head and being grouped together to define an initial color pattern. The colored filaments comprise at least a first and a second type of filament, wherein the types of filaments differ in color-changing characteristics over a pre-defined period of time, the pre-defined period of time being the same for the first and the second type of filament so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern, the first color pattern being different form the initial color pattern.
Claims18
A head for an oral-care implement, the head comprising:
- a plurality of colored filaments extending from a mounting surface of the head and grouped together to define an initial color pattern,
- the plurality of colored filaments comprising at least a first type of filament having an initial color and a second type of filament having an initial color, wherein said first and second types of filament differ from one another in their respective color-changing characteristics over a pre-defined period of time,
- wherein the pre-defined period of time is the same for the first type of filament and the second type of filament, so that the initial color pattern changes its color characteristics over at least a first pre-defined period of time to a first color pattern that is different from the initial color pattern,
- wherein the initial color of the first type of filament differs from the initial color of the second type of filament,
- wherein each of the first type of filament and the second type of filament changes its initial color to a first color, respectively, and
- wherein the first color of the first type of filament is substantially the same as the first color of the second type of filament and
- wherein the head further comprises at least a third type of filament having an initial color contributing to the initial color pattern, wherein the third type of filament changes its initial color to a first color, and wherein the first color of the third type of filament differs from at least one of the first color of the first type of filament and the first color of the second type of filament.
A head for an oral care implement, the head comprising a number of colored filaments extending from a mounting surface of the head and being grouped together to define an initial color pattern, the colored filaments comprising at least a first type of filament and a second type of filament, wherein the first and second types of filaments differ in color changing characteristics over a pre-defined period of time, the pre-defined period of time being the same for the first type and the second type of filament so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern, the first color pattern being different from the initial color pattern,
- wherein the first type of filament has an initial color that is different from the initial color of the second type of filament to define the initial color pattern, and
- wherein the head further comprises a third type of filament contributing to the initial color pattern, wherein the third type of filament has an initial color that is different from the initial color of the first type of filament and the initial color of the second type of filament,
- wherein each of the first type of filament and the second type of filament changes its initial color to a first color, respectively,
- wherein the first color of the first type of filament is substantially the same as the first color of the second type of filament,
- wherein the third type of filament changes its initial color to a first color, and
- wherein the first color of the third type of filament differs from the first color of the first type of filament and the first color of the second type of filament.
