20230263293
The present invention relates generally to an artist/make-up brush device, and more specifically to a brush device that consists of a pen-type cylinder with an individual brush tip, wherein the brush tip is selectively interchangeable, retractable, and sanitizable.
Prior brushes have tried to address the problem of both utilizing retractable bristles to address self-styling and concerns regarding interchangeability with limited success. Some prior retractable bristle brushes utilize complicated systems of movement that increase the cost of manufacture of the brush, require two hands to operate effectively, and fail due to material collected within the operating components of the brush.
One example of a retractable bristle brush is disclosed in U.S. Pat. No. 5,815,877 to Heneveld. Heneveld provides a rectangular brush wherein bristles are retracted from the top side of the brush by moving a sleeve that holds the bristles along a bottom side of the brush, retracting the bristles into the brush handle.
Several prior art brushes provide circular bristle sections that require extensive mechanical systems and movement to retract and/or extend the bristles. U.S. Pat. No. 6,070,594 to Mears discloses a circular brush having bristles mounted on rotatable axles, which are then moveably mounted on an inner mandrel with the bristles extending through slots through an outer mandrel rotatably mounted on the brush. The system requires a user to rotate the inner mandrel in relation to the outer mandrel while maintaining the brush in a styling position to retract the bristles.
U.S. Pat. No. 4,596,261 to Renda et al. discloses a complicated system utilizing cams and grooves, and includes several control mechanisms to retract and extend the bristles. The brush as disclosed does not provide for one-handed use in styling one's hair.
U.S. Pat. No. 4,567,905 to Stewart et al. discloses another version of a cam operated slidable retractable bristle brush. The bristle retraction control operates by co-action with a rotatable cylindrical mandrel having pivotal bristles.
U.S. Pat. No. 5,109,877 is retractable and has multiple brush tips contained within a single unit. This configuration has several drawbacks to the make-up artist. First, it has a relatively large diameter which makes it less desirable to a make-up artist. Second, the multiple tips that retract into a single unit have the potential for mixture of particulates from the different brush heads.
The prior devices, as described above, have several problems. Some can only accommodate a single brush stick. When more than one brush stick is used selectively, the change cannot be accomplished rapidly, or the change results in an undesirable mixing of particulate from the various brush heads.
It is thus desired to provide a replaceable brush that has a streamlined body wherein the artist may rapidly use.
The subject invention solves the above problems by offering a make-up brush device including a pen-type cylindrical container capable of accommodating a brush head having a quick connect/disconnect that allow the user to quickly and easily change brush heads with a single handed motion for particular needs or purposes.
The brush device according to the present invention generally includes a cylindrical casing, usually in the shape of a pen.
In one embodiment, the brush device of the present invention comprises: (a) a cylindrical casing having an orifice in a head end and a closed rear end; and (b) a retractable mandrel positioned within the cylindrical casing extending longitudinally in the cylindrical casing; wherein the mandrel is slidably mounted in the casing, the mandrel further comprising a means for controlling mandrel extension between an open position wherein the bristles extend through the orifice and a closed position wherein the bristles are retracted to a position within the cylindrical casing. The sliding track uses a Track Initiating Divot (TID) at the proximal and distal ends respectively of the sliding track. This is to lock the mandrel into the open and closed positions. A make-up brush tip is mounted on the mandrel whereby the make-up brush tip is positioned for axial sliding movement therein.
The brush device described may be configured for use by artists and for make-up (i.e., cosmetic) applications.
The brush device of the present invention weighs less than about 10 grams. In one embodiment, the make-up brush device of the present invention weighs less than about 8 grams. In a preferred embodiment, the make-up brush device of the present invention weighs between about 6-8 grams.
The brush device comprises a make-up brush tip mounted on the end of a mandrel. The tip and mandrel further comprise opposing quick connect/disconnect means. This allows the user to quickly and easily change make-up brush tips while utilizing a single handle. In one embodiment, the quick connect/disconnect is achieved through using a single magnet on the mandrel which meets with a metal attraction plate on the proximal end of each retractable tip.
The brush device cylindrical casing comprises a plurality of ridges on the surface interacting with an interlock means attached to the mandrel as a means of moving the mandrel. There is an interlock means that secures the mandrel into a fixed position.
In one embodiment, the brush device comprises a single mandrel.
The mandrel has an interlock connected thereto as a control and interlock means wherein the interlock extends from the surface of the mandrel and extends outward through the surface of the cylinder. The sliding track uses a Track Initiating Divot and a Track Terminating Divot at the proximal and distal ends respectively of the sliding track. This is to lock the mandrel into the open and closed positions.
Further contemplated is a method for applying make-up comprising the steps of: (a) selecting a first desired brush tip; (b) extending a mandrel from a retractable brush device to receive a brush tip; (c) securing the selected brush tip to a brush device with quick connect/disconnect using a single magnet on the mandrel which meets with a metal attraction plate on the proximal end of each retractable tip; (d) using the brush device with the brush tip secured to apply a first make-up; (e) removing the first brush tip by disengaging the brush tip by a quick connect/disconnect; (f) selecting a second brush tip; (g) securing the second brush tip to a device by means of a quick connect/disconnect; (h) retracting the second brush tip into a device with a retractable means for retracting the brush tip within a casing.
The invention also includes a brush kit comprising: (a) a device for holding brush tips, wherein the device comprises means for exposing, retracting, and storing a single removable brush tip; (b) a plurality of brush tips, wherein each brush tip may be quickly attached and detached from a holder through use of a quick connect/disconnect; (c) a case for containing the device and the brush tips, the case having a base and a cover, the case having an ultra violet light source with electronic board, battery source, and a timer switch placed on the inside a cover of the case and the base and cover of the case are constructed and arranged such that when the case is closed, the ultraviolet light turns on and sanitizes brush tip bristles placed thereon. The light further is controlled by a timer switch incorporated into the electronic board such that the ultraviolet light illuminates for a preset period of time up to five minutes and the light automatically switches off when sanitization is complete.

The ultraviolet light may take a variety of forms including traditional ultraviolet lamp-based lights in which electricity is passed through a filament which heats up and excites mercury vapor contained in the lamp. The ultraviolet light may also take the form of an ultraviolet LED light (for example, 4 to 8 LED lights). The utilization of an ultraviolet LED light would minimize the power requirements and would also allow for more strategic placement of the ultraviolet LED light(s).
In one embodiment, as seen in
It is contemplated that the present invention be part of a kit. Both novice and professional make-up artists may use the invention. Additionally, artists will be able to exchange paintbrush tips with the present invention. The user will be able to select brush tips that will quickly and easily attach to the mandrel on the subject invention. The contemplated brush tips would include any of the make-up applications commonly known.
Unlike prior attempts at multi-tip brush devices, the present invention will be streamlined and will not be particularly cumbersome as devices that contain multiple attached brushes. It is known in the art that heavy brushes do not balance well in the hand of the make-up artist, and do not allow for maximum detail dexterity.
In accordance with another embodiment of the present invention, and with reference to
The mandrel 110 is generally an elongated member shaped and dimensioned for comfortable handling by a make-up art or an individual applying make-up to himself/herself. As such, the mandrel 110 includes a first end 116 and a second end 118. The first end 116 includes a gripping surface 120 for engagement with the hand of the make-up artist. The second end 118 of the mandrel 110 is shaped and dimensioned for selective engagement with the plurality of make-up brushes 112a-f (see
As discussed above, the present make-up brush system 100 provides for the convenient use of a plurality of different make-up brushes 112a-f. It is appreciated that a plurality of such brushes are known in the art. In accordance with a preferred embodiment, the make-up brushes 112a-f used in accordance with a preferred embodiment of the present invention are selected from the group consisting of any animal hair, any synthetic hair, and man-made fiber and foam product.
Each of the make-up brushes 112a-f making up the plurality of make-up brushes used in the present make-up brush system 100 includes a first end 124 and a second end 126. The first end 124 includes, what may be thought of as, the functional component of the make-up brush 112a-f. For example, and with reference to make-up brush 112a, the first end 124 includes brush bristles 128 as discussed above with regard to the prior embodiments. The second end 126 of each of the plurality of make-up brushes 112a-f includes an identical coupling member 130, that is, the brush tip as discussed above with regard to the prior embodiments, shaped and dimensioned for selective engagement with the second end 118 of the mandrel 110.
With this in mind, and with particular reference to
In addition to the mandrel 110 and the plurality of make-up brushes 112a-f, the present make-up brush system 100 includes a case 114 providing for the sanitizing of the various functional elements of the present make-up brush system 100 and for the convenient exchange of the plurality of make-up brushes 112a-f upon the second end 118 of the mandrel 110.
The case 114 includes a base 138 and a cover 140. The base 138 and cover 140 are connected by a hinge 142 allowing for the cover 140 to move between an open configuration where the contents of the case 114 are exposed and a closed configuration where the contents of the case 114 are fully enclosed within the case 114.
In particular, the cover 140 is substantially rectangular in shape and includes first and second short side walls 144, 146 and first and second long side walls 148, 150 depending from the cover wall 151, as well as an external surface 152 and an interior surface 154 on opposite sides of the cover wall 151. A mirror 153, with a surrounding bezel, is mounted along the interior surface 154 of the cover wall 151 in accordance with a disclosed embodiment. Similarly, the base 138 is substantially the same shape as the cover 140 and is therefore rectangular in shape and includes first and second short side walls 156, 158 and first and second long side walls 160, 162 depending from the base wall 163, as well as an external surface 164 and an interior surface 166 on opposite sides of the base wall 163. When in the closed configuration the short side walls 144, 146 and long side walls 148, 150 of the cover 140 align with the short side walls 156, 158 and long side walls 160, 162 of the base 138 with the respective external surfaces 152, 164 of the cover wall 151 and the base wall 163 facing away from each other.
As briefly discussed above, a hinge 142 connects the base 138 to cover 140. In accordance with a preferred embodiment, the hinge 142 is formed between the first long side wall 148 of the case 114 and the first long side wall 160 of the base 138. In this way, the first long side wall 148 of the case 114 and the first long side wall 160 of the base 138 are held adjacent to each other as the case 114 is moved between its open configuration and its closed configuration. The second long side wall 150 of the case 114 and the second long side wall 162 of the base 138 are, in contrast, permitted to move toward and away from each other as the case 114 moves between its closed configuration where the second long side wall 150 of the case 114 and the second long side wall 162 of the base 138 are in contact such that the interior contents of the case 114 are hidden therein and the open configuration where the second long side wall 150 of the case 114 and the second long side wall 162 of the base 138 are spaced from each other allowing the make-up artist access to the contents of the case 114. The case 114 further allows for selective fastening of the case 114 in a closed configuration and opening thereof when desired.
Access to the make-up brushes 112a-f held within the case 114 is achieved by providing a tray 168 within the base 138 for supporting the plurality of make-up brushes 112a-f in accessible positions within the case 114. The tray 168 sits within the interior space 170 of the base 138 as defined by the interior surface 166, the first and second long side walls 160, 162, and the first and second short side walls 156, 158. With this in mind, the tray 168 includes an upper support surface 172 and downwardly extending appendages 174 which are positioned adjacent the first and second long side walls 160, 162, and the first and second short side walls 156, 158 such that the support surface 172 sits above the free edges 156f, 158f, 160f, 162f of the respective first and second long side walls 160, 162 and the first and second short side walls 156, 158. In this way, and as will be appreciated based upon the following detailed discussion, the mandrel 110 may be moved into position relative to the base 138 for selective engagement with the plurality of make-up brushes 112a-f.
The upper support surface 172 of the tray 168 includes a plurality of retention recesses 176 shaped and dimensioned for receiving and supporting a particular make-up brush 112a-f. Each of the retention recesses 176 is shaped and dimensioned to frictionally hold a make-up brush 112a-f and release the same when adequate force is applied. As all of the retention recesses 176 are functionally identical, with minor variations to accommodate various shapes of the make-up brushes 112a-f, a representative retention recess 176 is described below.
The retention recess 176 includes opposed side walls 178a, 178b and a base wall 180 connecting the opposed side walls 178a, 178b. The opposed side walls 178a, 178b and base wall 180 define a cavity 182 shaped and dimensioned for receiving a make-up brush 112a-f. While the front end 184 of the retention recess 176 is closed by a front wall 186, the rear end 188 of the retention recess 176 is open for the passage of the second end 118 of the mandrel 110 into the retention recess 176, and ultimately into the coupling member 130 at the second end 126 of the make-up brush 112a-f.
Retention of the make-up brushes 112a-f within the tray 168 for both removal and return of the make-up brushes 112a-f is achieved by the provision of a selective coupling mechanism between the make-up brushes 112a-f and the retention recess 176. In particular, between the first end 124 and the second end 126 of each make-up brush 112a-f is provided a brush body 190. The brush body 190 includes a circumferentially coupling recess 192 extending about the center thereof.
Similarly, each of the retention recesses 176, between the front end 184 thereof and the rear end 188 thereof, includes coupling detents 194a, 194b respectively extending from the opposed side walls 178a, 178b of the retention recess 176. The coupling detents 194a, 194b are of a size to fit within the circumferential coupling recess 192 of the brush body 190.
The interaction between the coupling detents 194a, 194b and the circumferential coupling recess 192 allows for selective retrieval and return of the make-up brushes 112a-f with only a single hand. Retrieval and return, as well as retention within the retention recesses 176, are facilitated by the integration of a magnet 177 (in particular, a rare-earth magnet) into each of the retention recesses 176 (preferably along the underside of the tray and thereby hidden from view) in the area of the metal shim 134 of the brushes 112a-f (see
In particular, and assuming the second end 118 of the mandrel 110 is free of any make-up brushes 112a-f and the plurality of make-up brushes 112a-f are sitting within their respective retention recesses 176 within the tray 168 of the case 114 with the metal shims 134 of the make-up brushes 112a-f engaged with the magnets 177 of the retention recesses 176, the second end 118 of the mandrel 110 is positioned in alignment with the rear end 188 of a retention recess 176 in which a desired make-up brush 112a-f is sitting. The second end 118 of the mandrel 110 is then moved toward the second end 126 of the make-up brush 112a-f and within the coupling member 130 thereof. With the mutual attraction of the metal shims 134 in the second ends 126 of the make-up brush 112a-f and magnetic member 136 in the second end 118 of the mandrel 110, the mandrel 110 is now coupled with make-up brush 112a-f.
However, the interaction between the circumferential coupling recess 192 of the brush body 190 and the coupling detents 194a, 194b prevents the make-up artist from simply pulling the make-up brush 112a-f rearward out the rear end 188 of the retention recess 176 along a line of force substantially parallel to the plane in which the upper support surface 172 of the tray 168 sits. The make-up brush 112a-f is, however, able to move upwardly away from the upper support surface 172 of the tray 168 in a direction substantially perpendicular to the plane in which the upper support surface 172 of the tray 168 lies, and away from the magnetic attraction between the magnetic 177 in the retention recesses 176 and the metal shim 134 of the make-up brush 112a-f.
With the make-up brush 112a-f coupled to the mandrel 110 and removed from the case 114 for use as the make-up artist sees fit, the make-up brush 112a-f may be used until such a time that the make-up artist, or lay-person, desires to return the make-up brush 112a-f to the case 114 (because the job is finished or because the make-up artist wishes to use a different make-up brush). When it comes time to return the make-up brush 112a-f to its retention recess, the circumferential coupling recess 192 of the brush body 190 and the coupling detents 194a, 194b once again prevent the make-up artist from simply pushing the make-up brush 112a-f forward into the rear end 188 of the retention recess 176 along a line of force substantially parallel to the plane in which the upper support surface 172 of the tray 168 sits. Rather, the make-up brush 112a-f is moved in the reverse direction of how it was removed, that is, the make-up brush 112a-f and the mandrel 110 are moved downwardly toward the upper support surface 172 of the tray 168 in a direction substantially perpendicular to the plane in which the upper support surface 172 of the tray 168 lies such that the circumferential coupling recess 192 of the brush body 190 and the coupling detents 194a, 194b align. Once in this position, the magnetic attraction between the magnets 177 into each of the retention recesses 176 and the metal shim 134 of the make-up brushes 112a-f help to hold the make-up brushes 112a-f within the retention recesses 176.
With the circumferential coupling recess 192 of the brush body 190 and the coupling detents 194a, 194b aligned and the make-up brush 112a-f sitting within the retention recess 176, the make-up art may remove the mandrel 110 from the make-up brush 112a-f by pulling rearward with sufficient force to overcome the magnetic attraction of the magnetic member 136 at the second end 118 of the mandrel 110 and the metal shim 134 at the second end 126 of the make-up brush 112a-f. It is appreciated, the interaction between the circumferential coupling recess 192 of the brush body 190 and the coupling detents 194a, 194b of the retention recess 176 prevent removal of the make-up brush 112a-f when the make-up artist pulls rearward to remove the mandrel 110 from the make-up brush 112a-f.
In addition to providing for the support and retrieval of the make-up brushes 112a-f, the case 114 also provides for sanitizing of the various functional components. An interior surface 154, 166 of the cover wall 151 or the base wall 163 (in accordance with a disclosed embodiment it is the base 138) is provided with battery(ies) 196, an electronic circuit board 198 and ultraviolet lights 200a, 200b. While battery(ies) 196 are disclosed herein, it is appreciated the conventional battery(ies) may be replaced with rechargeable battery(ies) or another power source connected to a USB power port for convenient recharging. The circuit board 198 has power wires 202 supplying power from the batteries 196. The circuit board 198 also has supply wires 204 that supply power to the ultraviolet lights 200a, 200b. An actuator 206 is linked to the base 138 and cover 140 such that the actuator 206 transmits a signal to circuit board 198 when the cover 140 is closed upon base 138. The signal initiates power from the circuit board 198 to the ultraviolet lights 200a, 200b for a preset period. While the ultraviolet lights are powered, an indicator light 210 is illuminated along the long side wall 162 of the base 138. In a preferred embodiment, ultraviolet light is illuminated for 1-5 minutes (which may be readily adjusted by reprogramming the electronic circuit board 198).
In accordance with a disclosed embodiment, the ultraviolet lights 200a, 200b are elongated ultraviolet lights 200a, 200b and are positioned within a cavity 211a, 211b in the front wall 186 of the retention recess 176. The ultraviolet lights 200a, 200b are covered with quartz window members 222a, 222b that are positioned along the exposed portions of the cavities 211a, 211b to provide protection to the ultraviolet lights 200a, 200b positioned therein. In accordance with a disclosed embodiment, the retention recesses 176 lead to respective brush end recesses 212 in which the ends of the brushes 112 are positioned so as to be adjacent to the ultraviolet lights 200a, 200b. Each of the brush end recesses 212 includes a base 214 and upstanding walls 186, 216, 218, 220, wherein the upstanding wall 186 directly opposite the ends of the brushes 112 is the front wall 186 in which the ultraviolet lights 200a, 200b are respectively positioned and form part of the front wall 186 facing the ends of the brushes 112 for directly transmitting ultraviolet light thereupon. Each of the bases 214 is provided with a UV reflective material 224, for example, a metal sheet of aluminum or aluminum base alloy.
In accordance with a preferred embodiment, the ultraviolet light 200 functions with the following characteristics:
Wattage: 0.3 W±15%
Voltage: 160V±8
Power: 1.7 mA
254 nm output: 260 uW/cm{circumflex over ( )}2 (at surface)
Stability: 5 min
Life: 10000 hrs.
A lamp with these characteristics produces highly desirable results as shown in Table A.
Escherichlia coli
Staphylococcus aureus
Streptococcus lactis
As with the embodiment disclosed above, the ultraviolet light may take a variety of forms including traditional ultraviolet lamp-based lights. The ultraviolet light may also take the form of an ultraviolet LED light. The utilization of an ultraviolet LED light would minimize the power requirements and would also allow for more strategic placement of the ultraviolet LED light(s).
The present invention provides for a pen-like make-up brush device which is streamlined, lightweight, and accommodates interchangeable brush tips. The brush bristles are held in a shank. The shank, in turn, is connected to the mandrel by means of an appropriate quick connect means. The present invention is contemplated as being usable for all make-up applications. These would include, but would not be limited to, lip brush, concealer, eye shading, eyeliner, lash brush, blush brush, and a brow brush. Because the brush tips are easily removed and changed, the user is able to both effectively clean the various brush tips, and to customize the device for specific/personalized use. The ultraviolet light source with electronic board, battery source, and timer switch is placed in the cover and the base of the case such that when the case is closed the light comes on to sanitize the tip bristles. A timer switch is incorporated into the electronic board to keep the light sanitizing for five minutes while contained in the case. The light automatically switches off when sanitization is complete.
While the invention has been described in its preferred form or embodiment with some degree of particularity, it is understood that this description has been given only by way of example and that numerous changes in the details of construction, fabrication, and use, including the combination and arrangement of parts, may be made without departing from the spirit and scope of the invention.
While the preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention.
