Brushhead for use with a non-newtonian cosmetic composition

摘要

The brushhead includes a brushhead base member and at least one outer ring of bristles mounted thereto, the brush base member being non-oscillating. An inner assembly is adapted to capture a solid, semi-solid, gel or the like non-Newtonian balm element having shear thinning characteristics. In an embodiment, the inner assembly is adapted to receive energy from an oscillating action of the inner assembly produced by a motor in the appliance to which the brushhead is attachable. Oscillation of the inner portion at a target frequency and amplitude is sufficient to result in the solid, semi-solid, gel or the like balm element changing to a liquid in a shear thinning effect, the liquid being useful for removal of makeup.

主权项

1. A brushhead for use with a non-Newtonian cosmetic composition, comprising:
a brushhead base member, the base member remaining fixed in position relative to an associated appliance during operation of the appliance; at least one outer ring of bristles mounted on the base member and adapted for comfortable contact with the skin; and an inner brushhead portion adapted to capture a solid, semi-solid or gel non-Newtonian cosmetic composition which has shear thinning characteristics, the inner portion further adapted to receive energy by virtue of an oscillating action on the inner portion produced by a motor assembly in the appliance to which the brushhead is attachable, wherein oscillation of the inner portion at a selected frequency and amplitude results in a change of state of the non-Newtonian cosmetic composition from solid, semi-solid or gel to liquid, wherein the inner brushhead portion includes one or more rings of bristles, a plurality of elastomeric members supporting the non-Newtonian cosmetic composition and a central stake, taller than the elastomeric members, to which the non-Newtonian cosmetic composition is securable, so that the solid, semi-solid or gel non-Newtonian composition is maintained within the brushhead as the appliance changes orientation.
