Abstract
One embodiment of a head-switchable brush comprises a brush head, a ferrule, and a brush handle. The ferrule has the head at one end and the handle at the other end. There is a piece of magnet attached to the brush handle and ferrule respectively where the two parts connect. The brush head can be switched and assembled with the handle easily whenever needed. The ferrule can be kept firmly on the handle by the action of the magnet inside. The head-switchable function of this brush kit can greatly enlarge the brush applying space and also avoid the material wasting since this brush kit has one handle only but with various brush heads.
Claims30
A head-switchable cosmetic applicator, comprising:
- a head assembly including a ferrule having:
- (a) a first generally planar mating surface formed at least in part by a first magnetic element and (b) one of a recess or a projection;
- and
- a handle including:
- (a) a second generally planar mating surface formed at least in part by a second magnetic element and (b) the other of the recess or the projection;
- wherein the recess is non-magnetic and capable of receiving the projection;
- wherein at least one of the first and second magnetic elements is a magnet, and the head assembly is releasably attachable to the handle by magnetic attraction between the first and second magnetic elements creating a pulling force between about 0.4 lbf to about 1.2 lbf when the head assembly and the handle are attached;
- wherein the part of the first generally planar mating surface formed by the first magnetic element and the part of the second generally planar mating surface formed by the second magnetic element are in flush alignment when the head assembly and the handle are attached;
- and
- wherein the projection and the recess are both elongate and have longitudinal axes that substantially align with each other when the head assembly and the handle are attached and said recess is receiving said projection,
- wherein said projection includes a projection transverse cross section along at least one part along the length of said projection,
- wherein said recess includes a recess transverse cross section along at least one part along the length of said recess,
- wherein said projection transverse cross section and said recess transverse cross are shaped so as to interfere with each other so as to restrain the head assembly from rotation relative to the handle about the substantially aligned axes.

A head-switchable cosmetic applicator, comprising:
- a male component having:
- (a) a non-magnetic projection on a distal end of the male component and (b) a first magnetic element forming at least part of a distal-most generally planar surface of the male component;
- and
- a female component having:
- (a) a non-magnetic recess adapted to receive the projection in a forward end of the female component to form a mated configuration with the male component and (b) a second magnetic element positioned to be in flush alignment with the first magnetic element in the mated configuration,
- wherein one of the male component or the female component is a head assembly including a ferrule and the other of the male component or the female component is a handle;
- wherein at least one of the first and second magnetic elements is a magnet, and the head assembly is releasably attachable to the handle by magnetic attraction between the first and second magnetic elements creating a pulling force between about 0.4 lbf to about 1.2 lbf in the mated configuration;
- wherein the projection and the recess are both elongate and have longitudinal axes that substantially align with each other when the head assembly and the handle are attached and said recess is receiving said projection,
- wherein said projection includes a projection transverse cross section along at least one part along the length of said projection,
- wherein said recess includes a recess transverse cross section along at least one part along the length of said recess,
- wherein said projection transverse cross section and said recess transverse cross are shaped so as to interfere with each other so as to restrain the head assembly from rotation relative to the handle about the substantially aligned axes.
8 more elements
A cosmetic applicator assembly comprising a male component and a female component releasably attachable to one another, wherein:
- said female component includes a first magnetic element and a recess defining an open end thereof, and the male component includes a second magnetic element and a projection defining a distal end, the projection being insertable into the recess;
- and
- an applicator element positioned on the male component or the female component;
- wherein the first and second magnetic elements are positioned so that they hold the female and male components releasably together when the projection is inserted into the recess;
- wherein the projection and the recess are both elongate and have longitudinal axes that substantially align with each other when the head assembly and the handle are attached and said recess is receiving said projection,
- wherein said projection includes a projection transverse cross section along at least one part along the length of said projection,
- wherein said recess includes a recess transverse cross section along at least one part along the length of said recess, and
- wherein said projection transverse cross section and said recess transverse cross are shaped so as to interfere with each other so as to restrain the head assembly from rotation relative to the handle about the substantially aligned axes.
- wherein the pulling force between said first magnetic element and said second magnetic element when said head assembly and said handle are attached and said recess is receiving said projection is between about 0.4 lbf to about 1.2 lbf.
