BRUSH CARE SYSTEM
A brush care system is provided for cleaning, washing and drying brushes in beautification or painting. The system includes a washing part, a cleaning part and a drying part. The washing part and the cleaning part fit together for convenient storage while the cleaning part resides inside the system. The system may be sized to accommodate one or more brushes. The washing part may hold water, soap, liquid, or solution. The cleaning part allows water to be drained off and allows brush bristles to be rubbed against it to remove paint, dirt, cosmetics, and other material. The drying part functions as a stand for drying the cleaned brushes and is perforated to allow air circulation. The bottom of the drying part may be sealed so that a lower portion of it may hold clean water for rinsing. The washing part may be configured with more than one partition.

This application claims benefit of U.S. Provisional Patent Application 61/266,993, filed Dec. 4, 2009, entitled Brush Care System, inventors Diane Adler Baker and Malcolm Davenport Plant, which is hereby incorporated herein by reference in its entirety for all purposes.
The application is also related to issued U.S. Pat. No. 7,140,061 to Baker and Plant, which is hereby incorporated herein by reference in its entirety for all purposes.
BACKGROUND OF THE INVENTIONBrushes for fine arts and for cosmetics come in many shapes and sizes; they are valued and valuable tools. Often much of a user's time—time she would rather spend in beautification or painting or other activities—gets taken up by caring for and managing her brushes. It is important for people using any kind of cosmetics or paint to take care of brushes. For cosmetics, dirty brushes can cause skin irritation or infection and can carry impurities to the face and back into the cosmetic product. For paint, improper care will cause rapid deterioration, necessitating replacement. Good quality brushes are expensive, so brush preservation is important.
SUMMARY OF THE INVENTIONA brush care system is provided that has two parts which fit together for convenient storage. One part is a washing cup and is sized to accommodate a tablet of soap or other cleaning materials in the bottom of the cup. Tablet herein refers to a compacted form, such as a bar of soap (in contrast to a powder solid), and does not refer to a specific shape. A tablet can be any compacted shape. Water can be added to moisten (or immerse) the soap, while a cleaning screen retains the soap and allows a brush to be rubbed on the soap through the cleaning screen. The cleaning screen allows for gentle agitation of the brush bristles to more efficiently remove paint, dirt, cosmetics, and other material from the brush bristles. The cleaning screen also allows water or other fluid to be drained off while retaining the soap. The washing cup may be configured with more than one partition.
A second part functions as a stand for drying the cleaned brushes. This stand is perforated to allow air circulation. The stand may be a drying glass. The bottom of the drying glass may be sealed so that a lower portion of the drying glass may hold clean water for rinsing.
A brush care system 100 includes a drying glass 102 including a bottom 101, a wall or walls 103 and apertures 104a-104f, a brush cleaner 106 including a cleaning screen 108 including a removal handle 110, and a washing cup 112, as shown in
In one embodiment, apertures may be in the bottom 101 in the drying glass 102 for better ventilation when drying brushes. In another embodiment, the bottom 101 in the drying glass 102 may be sealed so clean water can be held in the lower portion 204 for rinsing the brushes, as shown in
In a preferred embodiment, the invention provides a dynamic cleaning system in which brush cleaner 106 rests atop surfactant tablet 114 and lowers within washing cup 112 over time as surfactant tablet 114 dissolves. In many uses, tablet 114 is a cake of soap or other soluble material, and cleaner 106 will lower very gradually as it dissolves, over many uses, so long as washing cup 112 is drained of water after each use.
The system is also hygienic because it provides for air-drying and air circulation, which minimizes the transfer of pollutants on cloth. The washing cup also enables proper disposal of cleaning materials and cleaned detritus.
A user takes brush 202 and scrapes, rubs, or agitates the bristles (not shown) against cleaning screen 108 to remove impurities, old cosmetics, detritus, and/or paint. A representative brush showing bristles or other brush fibers is depicted in U.S. Pat. No. 7,140,061
Cleaning screen 108 can comprise apertures defined by a grid (so that square or any other shaped apertures are defined), or can comprise another configuration of aperture and material, such as bars and spaces or pegs, so that a rough or differentiated surface is created that allows for friction and agitation of bristles.
Different configurations of apertures are provided for within the scope of the invention. Two different kinds of apertures are possible, which could be roughly characterized as asymmetric or symmetric. To distinguish the two, consider any aperture with respect to arbitrarily oriented perpendicular axes x and y within the plane of the (substantially flat) screen. Any aperture has a unique minimally enclosing rectangle with sides parallel to those axes. Consider the x dimension and the y dimension of that rectangle. If the ratio of these dimensions is outside of the range [0.67, 1.5], call the aperture asymmetric. For example, apertures formed as the gaps between parallel wires connecting two sides of a square aperture defined in the cleaner (screen or grid) would generally be asymmetric. If an aperture's ratio of x and y dimensions falls *within* [0.67, 1.5], call it symmetric. For example, roughly square apertures formed by a fine grid of parallel wire pieces with similar x and y pitch, would be symmetric. Of course, the apparatus can include a combination of different apertures, including both symmetric and asymmetric. The scope of the present invention encompasses both symmetric and asymmetric apertures as herein defined.
Clean water can be retained in a water-retaining portion 204 of drying glass 102 for rinsing. Then the clean water can be emptied and the user can place the brush in the stand bristles down, for drying. In an alternative, a notch or retainer is provided in drying glass 102 so as to retain brush 202 in an upright position. Apertures 104a-104f allow for air circulation. Before placing a brush bristles down, a user preferably places a protective sleeve or other covering over the bristles. One example of such a protective sleeve is described in U.S. Pat. No. 7,140,061 to Baker et al., the contents and all aspects of which are incorporated herein by reference for all purposes. In alternatives, other covers, sleeves, or cups can be placed over the bristles before the brush is placed bristles-down in the drying glass.
In one embodiment, the washing cup 112 is configured as having one receptacle for liquid or cleaner, as shown in
In other embodiments, it is possible to have more than one receptacle in the washing cup 112, which can be defined by a partition or an enclosure or separated area in the washing cup. The advantage is to individually contain more than one kind of water, liquid or solution in one washing cup. One partition may contain a solution for cleaning while another may contain clean water for rinsing. When there are two or more receptacles, the receptacles may or may not have the same shape as the washing cup. In one embodiment, a washing cup is round and includes two partitions configured as two half circles. In one embodiment, a round washing cup with plural receptacles may be configured as two circles with different diameters that are concentric or non-concentric. Partitions are enabled by a divider or dividers in-between which are either as high as or lower than the washing cup. The dividers may be made of the same material as the washing cup. With larger systems for plural brushes, more receptacles may be needed.
In the preceding specification various embodiments and aspects of the present invention has been described with reference to specific examples thereof. It will, however, be evident that various modifications and changes may be made without departing from the broader spirit and scope of the present invention as set forth in the claims that follow. The specification and drawings are accordingly to be regarded in an illustrative rather than restrictive sense. These and other variations upon and modifications to illustrated embodiments are provided for by the present invention, the scope of which is defined by the following claims.
