Field of the Invention
[0001] The invention relates to a retainer for retaining a handle of a brush, particularly
a makeup brush, such that the brush can be spun.
Background
[0002] Used makeup brushes harbour bacteria. Such bacteria may be harmful to skin or to
the general health of users of such makeup brushes, particularly as makeup brushes
are typically used to apply makeup to the face, where skin is delicate. Effective
cleaning of makeup brushes can be problematic.
[0003] A solution, which the inventor devised, that is effective at cleaning makeup brushes
is to attach a handle of a makeup brush to a motorised device, which can be operated
to spin the brush about its length. The fibrous end of the brush can then be spun
in a cleaning liquid and then spun in air for drying. In order to attach the handle
to the motorised device, the motorised device includes a mount attached to an end
of a rotatable drive shaft, and a connector piece couples the mount to the brush handle,
such that the brush extends lengthwise with an axis of the drive shaft.
[0004] Such a device has to be able to retain and spin brushes having handles of many different
shapes and sizes. Accordingly, it is known to provide such a motorised device with
several connector pieces, each configured to accommodate a brush of a different size.
Each connector piece can be removed from the device and replaced with another.
[0005] Unfortunately, sometimes brushes come loose from known connector pieces. Also, sometimes
it is difficult to remove a brush from a known connector piece. Furthermore, a large
number of connector pieces may be required to retain brushes with handles of a wide
variety of different shapes and sizes. It is an object of the present invention to
address such problems.
Summary of the Invention
[0006] In accordance with an aspect of the present invention, there is provided a retainer
adapted to retain a handle end of a brush, comprising: an end attachable to a mount;
another end comprising a collar in which the handle end can be secured, wherein the
collar has an irregular, or stated slightly differently, "non-smooth," interior surface
to facilitate securing of the handle end in the collar, wherein, when the handle end
is secured in the collar, spinning of the mount about a spinning axis thereof causes
spinning of the brush about the axis.
[0007] The problems described above are at least partially addressed. The collar or the
retainer as a whole may be formed of a resilient material, permitting flexibility
or deformation. The irregular interior surface facilitates deformation of and/or gripping
may the collar, thus facilitating the securing of the handle end in the collar. In
some embodiments, the collar may be stretched over the handle end. The irregular interior
surface may have at least one of: one or more protrusions extending from the interior
surface, one or more indentations in the interior surface, and one or more holes through
the collar from the interior surface to an exterior surface.

the interior surface may comprise a plurality of ridges, knurls, or other projections.
The one or more of indentations in the interior surface may comprise a plurality of
grooves or dimples.
[0009] The collar may have a concertinaed configuration, wherein ridges and channels in
the concertinaed configuration extend lengthwise with respect to a length of the collar.
The retainer may be formed of resiliently deformable material, such that the collar
can be stretched from an unstretched configuration to a stretched configuration in
order to locate and retain the handle end of a brush. The one or more ridges may be
bevelled towards an opening of the collar. The one or more surfaces between a peak
of a ridge and an adjacent trough of a channel may have a groove therein, extending
substantially parallel or lengthwise with respect to a length of the peak.
[0010] The collar may be between 5 mm and 30 mm. The irregular surface may have surface
features that are evenly spaced, circumferentially.
[0011] Preferred and/or optional features of the retainer are set out in the dependent claims.
There is also provided a set comprising a plurality of such retainers. There is yet
further provided a motorised device comprising such a retainer. Further, a retainer
may be provided with a plurality of brushes having handle ends of different shaped
and/or sized circumferences, which the respective retainer is adapted to retain. A
plurality of brushes may be used with the set of retainers, or provided therewith,
wherein a first of the retainers is configured to securely retain some of the brushes
but not others, whereas a second of the retainers is configured to securely retain
at least some of the other brushes but not those that the first retainer is configured
to retain.
[0012] In accordance with another aspect of the invention, there is provided a method of
cleaning or drying a makeup brush using a retainer and a handheld motorised device:
securing a mounting end of the retainer to a mount on a drive shaft of a motorised
device; securing an end of a handle of the makeup brush in a collar of the retainer
by locating the end of the handle in the collar, wherein the collar has an irregular
interior surface to facilitate securing of the handle end in the collar; locating
a fibrous end of the makeup brush in a cleaning liquid for cleaning or in air for
drying; operating the motorised device to spin the drive shaft and the makeup brush.
[0013] The irregular interior surface may have at least one of: one or more protrusions
extending from the interior surface; one or more indentations in the interior surface;
and one or more holes therethrough from the interior surface to an exterior surface.
[0014] The one or more protrusions may have ridges, knurls or other projections. The one
or more indentations may comprise a plurality of grooves or dimples. The collar has
a concertinaed configuration, wherein ridges and channels in the concertinaed configuration
extend lengthwise with respect to a length of the collar. The collar or the retainer
as a whole may be formed of resiliently deformable or resiliently flexible material.

Detailed Description of Embodiments
[0016] Embodiments of the invention relate to a connector in the form of a retainer, for
retaining a handle end of a brush so that the brush can be spun by a motorised device
about its length. A fibrous end of the brush can thus be spun in a cleaning liquid
for cleaning and in air for drying.
[0017] The motorised device is intended for use with makeup brushes, but use of the device
is not limited to such. The retainer may be used to retain paint brushes, for example.
The retainer may be used generally for retaining ends of predetermined elongate implements
or other members, particularly where spinning is beneficial.
[0018] Referring to Figure 1A, in an embodiment the device includes an elongate body 10,
a user control in the form of a button 12, a first light 14, a second light 16, and
a mount 18. The mount 18 enables attachment of a brush to the device using a retainer.
The mount 18 comprises a base 22 and a cross-shaped mounting piece 20, as also indicated
in Figure 1B.
[0019] Referring to Figures 2A, several brush retainers in accordance with embodiments are
shown at 24a-h. A collar portion, in the form of brush grip end 26a-h, of each retainer
is configured to receive and retain a handle end of a brush. Each of the retainers
is sufficiently resilient and flexible in order to securely retain handle ends of
a limited range of different sizes and shapes, such that a retained brush is securely
retained during spinning. Together the brush retainers 24a-h can retain a wide variety
of shapes and sizes of brush handle ends.
[0020] As can be seen from Figures 2B and 2C, each retainer 24a-h has a mount end 28a-h.
Each mount end 28a-h has a hole therein of the same or similar size and shape, and
is to enable mounting on the mounting piece 20. The hole of each of the retainers
24a-h has a square cross-section. The mount 18 and each mount end 28a-h are respectively
shaped to cooperate so that the respective retainer can be detachably secured to the
mounting piece 20. Each of the retainers can be pushed onto the mounting piece 20
and, due to the nature of the material from which the retainers are made and the shape
of the mounting piece 20, that is, the resiliently deformable nature of the material
and friction with the mounting piece 20, the retainers 24a-h remain fixedly located
on the mounting piece 20 during spinning of a brush. In variant embodiments, only
a single retainer may be provided for use with the motorised device. In this case,
the mounting piece 20 and the retainer need not be configured to be detachable; the
retainer may, for example, be secured to the mounting piece with adhesive.
[0021] Each of the retainers 24a-h provides a generally cylindrical interior surface against
which the handle of a makeup brush grips. In variant embodiments, the interior surface
may have a generally non-cylindrical cross-section.
[0022] The interior surface is irregular, or non-smooth, and has a plurality of indentations
in the form of grooves therein extending lengthwise with respect to the retainer.
In other words, grooves extend lengthwise with respect to an axis about which the
retainer rotates. In embodiments, the grooves are evenly spaced, circumferentially.
In variant embodiments, the grooves may taper in width relative to a circumference
of the interior surface from the opening of the brush grip end 26a-h, to the mount
end 28a-h. In variant embodiments, the grooves may be deeper near the opening through
which an end of a brush handle is inserted than further into the brush grip end. In
variant embodiments, the grooves may, for example, extend diagonally relative to the
axis or in a wavelike manner. In embodiments, the grooves may be arranged in other
manners that gives rise to increased ability to flex the brush grip end, such that
range of brush handle end sizes that a retainer can retain is increased, and/or deforming
of the retainer when pushing of the brush hand end into the retainer requires less
force.
[0023] The cross-shaped cross-section of the mounting piece 20 usefully allows air to access
the interior of an attached retainer and prevents a vacuum effect within the retainer
preventing removal of the attached retainer from the mounting piece and/or an attached
brush from the retainer. The cross-shaped mounting piece 20 bulges at an end thereof
remote from the body 10 of the device. In other words a diameter across the cross
shaped piece tapers towards the motorised device. This helps with securing of the
mount end 28a-h on the mounting piece 20.
[0024] Referring to Figure 3A, the device includes a microcontroller 40, an electric motor
42 and a battery 44, all operatively coupled. The first and second lights 14, 16 and
the button 12 are also operatively coupled to the microcontroller 40.
[0025] The microcontroller 40 comprises a processor 46, a memory 48, a clock 50, and input/output
interfaces 52 operatively connected by a bus. Computer program codes are stored in
the memory executable by the processor to result in the microcontroller 40 having
the functionality ascribed to it herein. The electric motor 42 includes a drive shaft
(not shown), which the electric motor 42 is configured to rotate about an axis thereof.
The body 10 has an aperture therein through which the drive shaft extends. The mount
18 is mounted on the drive shaft. The retainers 24a-h are respectively configured
so that when a retainer 24a-h is mounted on the mounting piece 20 and a brush retained
by the retainer 24a-h is spun, the brush spins substantially coaxially with the axis
of the shaft.
[0026] The microcontroller 40 is configured to control the electric motor 42. The button
12 is operable to cause the microcontroller 40 to cause the electric motor 42 to initiate
spinning of the drive shaft. The microcontroller 40 is configured to control the first
light 14 and the second light 16 to indicate status to the user, for example, whether,
further to initiating spinning, the user should move the fibrous end from being in
liquid to air.
[0027] The battery 44 is accessible through a cap 30 in a base 32 of the device, as indicated
in Figure 1C. The battery 44 is coupled to the microcontroller 40 and the electric
motor 42 to power the device. The battery 44 is in the form of replaceable batteries
such as the AA kind, although other types of battery may be used instead. Alternatively,
the device can include a charging port enabling connection of an exterior power supply
to the battery 44 for charging of the battery 44. The charging port may be configured
in any one of a variety of ways. For example, the device may include a micro-USB port.
Preferably, such a port is covered during use of the device by an openable seal to
prevent the possibility of ingress of cleaning liquid into the charging port. Alternatively,
the device may lack a battery, and be connectable to a mains power supply.
[0028] The inventor has found that a preferred rate at which the brushes should be spun
is between 2300 and 3300 revolutions per minute (rpm). Different brushes for cleaning
using the device have different masses. The electric motor 42 is preferably configured
to spin brushes in this range. To rotate a brush in this range, the electric motor
42 may require a greater supply of power to spin a heavier brush than a lighter brush
and the motor and the microcontroller 40 may be configured accordingly. In embodiments,
the microcontroller 40 may be configured to enable the user to select a higher power
for a heavier brush and a lower power for a lighter brush using the buttom 12.
[0029] Referring to Figure 3B, a receptacle in the form of a bowl 50 comprises a lower portion
52, which retains the cleaning liquid, and an upper portion 54, which serves as a
spray guard. The upper portion 54 defines a circular aperture through which a fibrous
end of a brush is inserted to locate the fibrous end in the cleaning solution. An
annular piece of plastic 56 is located around a rim to protect the upper portion 54,
since the brush may hit the sides of the aperture in use. The bowl may be transparent,
translucent or opaque. Other kinds of receptacle may be used to retain the cleaning
liquid, and into which the fibrous end of a brush may be spun using the device. The
cleaning liquid may be of any suitable liquid. For example, the cleaning solution
may be a water based soap solution or alcohol based, or other.
[0030] In use, a retainer is selected from the available retainers 24a-h that is a suitable
size for a particular brush that a user desires to clean. The selected retainer is
then attached to the device by pushing the mounting end of the respective retainer
onto the mounting piece 20. Before or after, the handle end of the brush is attached
to the handle end of the brush by pushing the end of the handle into the retainer,
causing the retainer to resiliently deform. In some embodiments, the retainer may
be stretched over the handle end. The brush can then be spun using the device. The
retainer and the brush are pulled apart after use. The retainer is also pulled from
the mount 18 after use.
[0031] A preferred cleaning method includes the following steps:
- a) Submerging of the fibrous end in the cleaning liquid and preferably pushing the
fibrous end against a base of the receptacle containing the cleaning liquid;
- b) Spinning the fibrous end in the cleaning liquid;
- c) Spinning the fibrous end in air, preferably in a space above the cleaning liquid
and below a rim of the receptacle, so that material sprayed from the brush is blocked
by the receptacle.
[0032] Other retainers in accordance with embodiments will now be described with reference
to the remaining Figures. Like with the retainers shown at 24a-h, each of the retainers
has a mount end having a hole for mounting on the mounting piece 20. Also, each of
the retainers has a collar portion in the form of a brush grip end. Each of the retainers
further has in the brush grip end thereof an irregular interior or exterior surface
having at least one of: indentations, protrusions, and holes. The indentations are
in an interior or an exterior surface of the brush grip end and the protrusions extend
from the interior or exterior surface of the brush grip end. The holes extend through
the material of the brush grip end from the interior surface thereof to the exterior
surface. The indentations, protrusions and holes aid in securing of a handle end of
a brush to the retainer, so that the brush can be attached to the mounting piece 20.
In particular, the indentations and holes increase ability to deform the brush grip
end to accommodate brush handle ends of different shapes and sizes, and the protrusions
resiliently deform, typically with the rest of a brush grip end, to grip a brush handle
end therein. According to some embodiments at least, the indentations, protrusions
and the holes reduce the number of retainers that have to be provided in order to
retain brushes of a wide range of shapes and sizes.
[0033] Referring to Figures 4i to 4iv, in an embodiment an interior surface 142 of a brush
grip end of a retainer 140 has a plurality of indentations therein in the form of
spaced dimples 144. These facilitate deforming or stretching of the retainer to receive
a handle end of a brush.
[0034] Referring to Figures 5i to 5iv, in an embodiment an interior surface 152 of a brush
grip end of a retainer 150 has a plurality of spaced projections 154 thereon, to facilitate
gripping.
[0035] Referring to Figures 6i to 6iv, in an embodiment an interior surface 162 of a brush
grip end of a retainer 160 has a plurality of spaced projections 164 thereon, to facilitate
gripping. There are a greater number per unit area of the interior surface than on
the retainer shown in Figures 5i to 5iv.
[0036] Referring to Figures 7i to 7iv, in an embodiment a brush grip end of a retainer 170
has a plurality of holes in the form of slits 172 therein. These facilitate deforming
and/or stretching of the retainer to receive a handle end of a brush.
[0037] Referring to Figures 8i to 8iv, in an embodiment an interior surface 182 of a brush
grip end of a retainer 180 has a plurality of spaced projections 184 thereon, to facilitate
gripping. There are a lesser number per unit area on the interior surface than on
the retainer shown in Figures 5i to 5iv.
[0038] Referring to Figures 9i to 9iv, in an embodiment an interior surface 194 of a brush
grip end of a retainer 190 has a plurality of protrusions thereon, that is, is knurled
or textured, for improved gripping.
[0039] Referring to Figures 10i to 10iv, in an embodiment a brush grip end of a retainer
200 has a plurality of holes 204 therethrough to facilitate stretching or deforming
of the retainer to receive a handle end of a brush.
[0040] Referring to Figures 11i to 11iv, in an embodiment a brush grip end of a retainer
210 has a multitude of densely packed indentations therein in the form of dimples
214, to facilitate stretching or deforming of the retainer to receive a handle end
of a brush.
[0041] Referring to Figures 12i to 12iv, in an embodiment an interior surface 224, 224a
of a brush grip end of a retainer 220 is a plurality of protrusions, that is, is knurled
or textured, for improved gripping. In this case, the knurled or textured surface
is discontinuous along the length of the brush grip end.
[0042] The retainers described above with reference to figures from Figures 4i to 12iv are
generally configured in the same way as the retainers described with reference to
Figures 2A to 2C, other than in the specific way in which the protrusions, holes or
indentations are configured, and are used in the same way.
[0043] Referring to Figures 13i to 13v and 14i to 14v, the two retainers shown have a generally
concertinaed or corrugated configuration providing flexibility. To achieve the concertinaed
or corrugated configuration, each retainer has a plurality of exterior ridges each
with a corresponding interior channel, and a plurality of exterior channels each with
a corresponding interior ridge. The ridges and channels are lengthwise with respect
to the retainer, that is, from an opening of the mount end to an opening of the brush
grip end.
[0044] The retainer 230 shown in Figures 13i to 13v has eight exterior ridges 232 and thus
eight exterior channels 234 between the exterior ridges. The retainer 240 shown in
Figures 14i to 14v has six exterior ridges 242 and thus six exterior channels 244
between the exterior ridges. In each case, the mount end 236, 246 of the respective
retainer is configured for mounting on the mounting piece 20. Each retainer 230, 240
is resiliently deformable, such that it can be stretched from an unstretched configuration
to a stretched configuration in order to locate and retain a handle end of a brush.
In variant embodiments, the mount end 236, 246 need not be in a concertinaed or corrugated
configuration. In variant embodiments retainers may have another number of outer ridges
and outer channels, for example from 4 to 12.
[0045] At an opening of the brush grip end of each of the retainers 230, 240, each interior
ridge 232, 242 is bevelled, as indicated at 239, 249. This facilitates location of
a brush handle end into the brush grip end of the retainer 230, 240.
[0046] A result of the concertinaed configuration is that an interior surface of each retainer
230, 240 comprises a plurality of peaks and troughs, a peak being at the apex of each
ridge and a trough being at the base of each channel. As indicated at 238 and 248,
in a surface between each peak and each tough, a groove is provided, which extends
lengthwise parallel to the peaks and troughs. The groove extends midway between each
peak and the adjacent trough. Such grooves 238, 248 have been found to improve flexibility
of the retainers and help with stretching and gripping.
[0047] In variant embodiments, the ridges, channels, peaks, troughs and grooves do not extend
lengthwise with the axis about which the retainer rotates in use. These may be otherwise
oriented to achieve the wanted effects. For example, they may taper towards the motorised
device.
[0048] In use, each retainer 230, 240 is stretched over a handle end of a brush to be retained.
Pushing the brush handle end into the retainer may also cause such stretching. After
cleaning, the brush is removed by pulling the brush and the retainer apart, the retainer
230, 240 returns to its initial unstretched configuration. Skilled persons will recognize
that each retainer 230, 240 can securely retain, in sequence, two brush handles of
significantly differing transverse sizes, due to the resilient deformability of ridges
232, 242.
[0049] A kit of a plurality of retainers configured to accommodate different sizes of brush
may be provided, such that at least one of the retainers can be used to accommodate
brush handle ends of a wide range of different sizes and shapes.
[0050] The retainers described above may be made from rubber (e.g. nitrile butadiene) and,
or another resiliently deformable material. In variant embodiments, retainers may
not be formed of a resiliently deformable material, particularly if the retainers
are for use with brushes or other elongate members in which a handle is resilient.
[0051] It will be appreciated by persons skilled in the art that various modifications are
possible to the embodiments.
[0052] Embodiments of the invention are not limited to any particular way in which the device
is coupled to the drive shaft so that rotational movement is transmitted to the brushes.
In variant embodiments, the mounting piece of the motorised device may be otherwise
shaped, and the mounting portions configured to engage with such a mounting piece.
[0053] Embodiments of the invention are also not limited to requiring rotation of the brushes.
In variant embodiments, the motorised device may be configured to cause a coupled
brush to move with other than rotational movement, while causing that retained brushes
to move in a manner that helps cleaning and/or drying of the brushes. For example,
the movement may be rapid back and forth movement.
[0054] Whereas the retainers described above enable spinning of an attached brush about
its length, in alternative embodiments the brush may be retained such that it is offset
with respect to a spinning axis and rotation of the brush is about the spinning axis.
In such case the spinning axis is the axis of the drive shaft.
[0055] The applicant hereby discloses in isolation each individual feature or step described
herein and any combination of two or more such features, to the extent that such features
or steps or combinations of features and/or steps are capable of being carried out
based on the present specification as a whole in the light of the common general knowledge
