Abstract

In a mascara brush, with a plurality of bristles fixed in place between two twisted wire segments and extending to all sides away from these twisted wire segments, the wire segments being surrounded by a plastic coating, it is provided, for the purpose of achieving increased liquid absorbing capacity, that the plastic coating consists of a fluid absorbent, in particular open-cell, foamed material.

It may further be provided that the foamed coating is roughened or fringed to such an extent that the bristles are formed by this roughening or fringing.

Claims

1. A mascara brush comprising a plurality of twisted wire segments (1) engaged together, each of the wire segments (1) being surrounded by a plastic coating, wherein the plastic coating consists of a open-cell, foamed material (4) formed with a plurality of pores per linear inch which absorb a liquid having a suspension of pigment particles.

2. A brush according to claim 1, wherein the foamed coating (4) has a wall thickness of between 0.1 and 1.5 mm.

3. A brush according to claim 1, wherein the foamed coating (4) has an elongation property of between 400 and 500%.

4. A brush according to claim 1, wherein the foamed coating (4) has a pores per linear inch count of between 5 and 150.

5. A mascara brush according to claim 1, wherein, during the plastic coating of the wire segments (1) or after the twisting of the coated wire segments (1), the foamed material (4) is mechanically or chemically roughened to form fibrous fringes (5).

6. A mascara brush according to claim 1 wherein a plurality of bristles (2) are fixed between the twisted wire segments (1) and extend to all sides away from the twisted wire segments (1).

7. A mascara brush according to claim 1 wherein the plastic coating is not reticulated.

8. A mascara brush comprising a plurality of twisted wire segments (1) engaged together, each of the wire segments (1) being surrounded by a plastic coating, wherein the plastic coating consists of a open-cell, foamed material (4) formed with a plurality of pores per linear inch which absorb a liquid having a suspension of pigment particles;

wherein the foamed coating (4) has an elongation property of between 400 and 500%.

9. A mascara brush comprising a plurality of twisted wire segments (1) engaged together, each of the wire segments (1) being surrounded by a plastic coating, wherein the plastic coating consists of a open-cell, foamed material (4) formed with a plurality of pores per linear inch which absorb a liquid having a suspension of pigment particles;

wherein the foamed coating (4) has a pores per linear inch count between 5 and 150.
