In an embodiment, a curing applicator for curing a curable formulation as it is applied to a surface includes an applicator assembly extending from a base assembly. The applicator assembly is configured to apply the curable formulation to the surface. The curing applicator further includes a curing assembly configured to deliver a curing stimulus. The curing assembly extends from the base assembly and is positioned to follow the applicator as it applies the curable formulation to the surface.
In an embodiment, a curing applicator for curing a curable formulation as it is applied to a surface, wherein the curable formulation contained in a container, includes an applicator assembly extending from a base assembly that is removably securable to the container. The applicator assembly is disposable within the container when the base assembly is secured to the container, and the applicator assembly is configured to apply the curable formulation to the surface. A curing assembly is configured to deliver a curing stimulus, wherein the curing assembly extends from the base assembly and positioned to follow the applicator as it applies the curable formulation to the surface.
In an embodiment, a method of curing a curable formulation as it is applied to a surface includes positioning a curing assembly relative to an applicator assembly such that the curing assembly follows the applicator assembly as it applies the curable formulation to the surface, and applying the curable formulation to the surface with the applicator assembly.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
Conventional nail polishes consist of solutions having solvents and other components, wherein the nail polish hardens after application by evaporation of the solvents. Improved “gel” nail polishes will cure much faster with the use of ultra violet (UV) lamps or light emitting diode (LED) lamps, depending on the gel formulation. The lamp typically includes an opening sized to receive substantially all the fingers of a user's hand, with the UV or LED bulbs on the top interior of the lamp. After applying one or more layers of nail polish to the user's fingers, the user inserts his or her hand into the lamp to allow the polish to cure. This step-by step process can take considerable time.
A specific type of UV or LED lamp must also often be used with a certain nail polish formulation. For instance, certain gel polishes will only cure under an LED lamp, and certain gel polishes will only cure under a UV lamp. Moreover, some polishes cure faster with stronger lamps, whereas other polishes only need a lower wattage lamp.
Thus, there is a need for an apparatus for curing a curable formulation, such as nail polish, that shortens the process, wherein the apparatus is individual and specific to the curable formulation to ensure that the proper curing technology or curing stimulus is used.
The above-described curing lamps, which receive the entire user's hand or at least a portion of the user's hand (such as all fingers except the thumb) also expose an unnecessary portion of the user's hand to potentially damaging light. More specifically, the user's hand and/or fingers could be damaged by repeated exposure to UV light or other types of light. Thus, there is an additional need for an apparatus for curing a curable formulation that minimizes unnecessary exposure of the user's skin to damaging light.
In an aspect, the present disclosure is directed to, among other things, to a curing applicator for curing a curable formulation, such as nail polish or another curable polymer, as it is applied to a desired surface or location, such as a user's fingernail. In an embodiment, “curable formulation” includes nail polish, varnish, lacquer, and the like, or any other type of material curable by a stimulus, such as a light-curable coating, material, polymer, composition, formulation, etc.
Moreover, the curing applicator uses a suitable “curing assembly” having a curing stimulus assembly with a curing stimulus capable of curing an intended curable formulation. For instance, the curing stimulus assembly may be defined by a light assembly having UV light or LEDs that are suitable for curing the curable formulation, such as nail polish. However, any other suitable curing stimulus assembly capable of curing the intended curable formulation may instead be used. Thus, the description and illustrations provided herein should not be seen as limiting the scope of the claimed subject matter.
Referring to
In the depicted embodiment, the base assembly 12 and applicator assembly 14 are generally designed to replace a cap and applicator brush of a nail polish bottle or other similar container (not shown). In that regard, the base assembly 12 is comprised of a substantially cylindrical cap portion 24 having an internal cavity with internal threads (not shown) for threadably engaging a threaded upper throat of a container, such as a nail polish bottle.
The applicator assembly 14 is comprised of an elongated stem 26 extending from an interior of the cap portion 24, with an applicator portion or tip 28, such as a brush, defined on the distal end of the stem 26. When the cap portion 24 is coupled to the nail polish bottle, for instance, the stem 26 and applicator tip 28 extend within the bottle such that the tip 28 may withdraw curable formulation contained within the bottle. It should be appreciated that any suitable cap and applicator tip may instead be used for the intended container and/or curable formulation. For instance, in some applications, a cap portion may not be necessary, and the base assembly 12 may instead be defined by a proximal end of the elongated stem 26 or another portion of the applicator assembly 14. As another example, the applicator assembly 14 may instead be comprised of a sponge or other type of material for applying the curable formulation to a surface.
The curing assembly 16 will now be described in detail. As noted above, the curing assembly 16 includes a curing stimulus assembly 29 configured to cure the curable formulation as it is applied to a surface by the applicator tip 28. In an embodiment, the curing stimulus assembly 29 is a light assembly 30 suitable for curing the curable formulation. In an embodiment, the light assembly 30 includes one or more energy emitters configured to deliver an electromagnetic energy stimulus. Non-limiting examples of energy emitters include arc flashlamps, radiation emitters, ion emitters, photon emitters, electron emitters, gamma emitters, thermal energy emitters, and the like. Further non-limiting examples of energy emitters include continuous wave bulbs, fiber lasers, lasers, incandescent emitters, laser diodes, lasers, light-emitting diodes, micro-cavity light-emitting diodes, micro-cavity resonators, organic light-emitting diodes, polymer light-emitting diodes, quantum dots, transducers, ultra-fast lasers, and the like.
In an embodiment, the light assembly 30 may be comprised of any suitable light-curing technology, such as for instance, light-emitting diodes (LEDs) (e.g., organic light-emitting diodes, polymer light-emitting diodes, polymer phosphorescent light-emitting diodes, microcavity light-emitting diodes, high-efficiency UV light-emitting diodes, and the like), ultraviolet (UV) LEDS, or other suitable LEDs, or any other suitable UV light source or other light-curing technology now known or later developed, and any combination thereof.
As a specific example, the light assembly 30 may be comprised of a UV light source that cures a curable formulation at 403 nm with a power of 36-46 mW/cm2. It can be appreciated that cure times may vary based on the formulation, volume, etc., of the curable formulation. For instance, certain UV curing polymers cure at shorter wavelengths, such as 365 nm.
In the depicted embodiment, the light assembly 30 includes first and second UV LEDs 34 and 40 secured within a portion of a light-positioning assembly 42, although fewer or more LEDs may instead be used. For instance, the light assembly 30 may instead include an array of LEDs spanning across a portion of the light-positioning assembly 42.
In an embodiment, the curing applicator 10 includes a power source. The power source is operably coupled to one or more components, modules, circuitry, sensors, and the like of the curing applicator 10. Non-limiting examples of power sources include one or more button cells, chemical battery cells, a fuel cell, secondary cells, lithium ion cells, micro-electric patches, nickel metal hydride cells, silver-zinc cells, capacitors, super-capacitors, thin film secondary cells, ultra-capacitors, zinc-air cells, and the like. In an embodiment, the curing applicator 10 is inductively coupled to a power source via one or more antennas. In an embodiment, the curing applicator 10 is wirelessly coupled to a power source via one or more antennas. In an embodiment, the power source is electromagnetically, magnetically, acoustically, optically, inductively, electrically, or capacitively coupled to one or more components, modules, circuitry, sensors, and the like of the curing applicator 10.
In an embodiment, the curing stimulus assembly 29 is powered by a suitable power source, such as a battery, located within the interior of the cap portion 24 (not shown). The battery may be replaceable through an opening in the cap portion 24, or instead rechargeable through an outlet in the cap portion 24. In the alternative, the curing stimulus assembly 29 may be powered solely through connection to a power source, such as by connecting to an electrical outlet. The power source is in electrical communication with the curing stimulus assembly 29 through a flexible electrical circuit, wire, etc., that may extend from the cap portion 24 to the curing stimulus assembly 29 through arms of the curing stimulus positioning assembly 42, which are later described. In the alternative, the power source (and any corresponding switch, outlet, etc.) and curing stimulus assembly 29 may both be disposed within the curing stimulus positioning assembly 42 such that no flexible circuit or wires are needed.
An illustrative block diagram showing an exemplary electrical architecture of the curing applicator 10 is shown in
The curing stimulus assembly 29 is disposed within a curing stimulus portion 46 of the curing stimulus positioning assembly 42. The curing stimulus portion 46 may be generally curved, or semi-cylindrical in shape, to substantially correspond to the contour of a user's fingernail or other desired surface. In that regard, a portion of the curing stimulus assembly 29 is positioned within the curing stimulus portion 46 to direct the curing stimulus onto a surface.
For example, in the depicted embodiment, the LEDs 34 and 40 of the light assembly 130 are positioned within the curved curing stimulus portion 46 to direct light downwardly and inwardly onto a fingernail positioned below. It should be appreciated that the curing stimulus portion 46 may instead be any other suitable contour, or the LEDs (or other curing stimulus) may instead be positioned within the curing stimulus portion 46 in another manner to direct light onto a desired surface. For instance, if LEDs are used, the LEDs may have specific exposure zones, such as cone-shaped zones ranging from 30-45 degrees (30-45°).
The curing stimulus portion 46 of the curing stimulus positioning assembly 42 extends from the cap portion 24 and is positioned above and outwardly from the applicator tip 28. More specifically, the curing stimulus portion 46 is positioned so that the curing stimulus assembly 29 may cure the curable formulation as it is applied to a surface by the applicator tip 28. For instance, as illustrated in
Any suitable structure may be used to position the curing stimulus portion 46/curing stimulus assembly 29 in this curing position. In the embodiment depicted in
Referring additionally to
In that regard, the cap portion 24 may include first and second opposing arm cavities 64 and 68 extending along the cap portion 24 that are sized and positioned to receive and stow the first and second arms 50 and 54 when the curing stimulus positioning assembly 42 is in the second, stowed position. It should be appreciated that the arms 50 and 54 may be made from a suitably flexible material to accommodate any interference between the arms 50 and 54 and the cap portion 24 when the arms are moved between the deployed and the stowed position.
The cap portion 24 may further include a curing stimulus portion cavity 72 defined near its end that is sized and positioned to receive the curing stimulus portion 46 when the curing stimulus positioning assembly 42 is in the second, stowed position. The arms 50 and 54 and the curing stimulus portion 46 are receivable within their respective cavities 64 and 68 and 72 such that they are substantially flush with the cap portion 24 when stowed. As such, the cap portion 24, together with the curing stimulus positioning assembly 42 (arms 50 and 54 and the curing stimulus portion 46) defines a substantially cylindrical structure that is graspable by a user.
In that regard, in the second, stowed position, the curing applicator 10 may be secured to a nail polish bottle or other container, similar to a standard nail polish bottle cap or other container cap. With the curing applicator 10 securable to an individual container, such as a nail polish bottle, the curing applicator 10 is tied to a specific curable formulation, such as a specific nail polish, that requires a specific curing stimulus technology. Moreover, the curing applicator can be used to cure only the surface on which the curable formulation is applied (such as the fingernail), rather than exposing a larger surface (such as the user's hand) to the curing technology. Furthermore, the curing stimulus technology is used as the curable formulation is applied, saving the user time.
Referring to
The curing applicator 110 includes a filtering element 180 secured to and extending from the curing stimulus portion 146. In one embodiment, the filtering element 180 is a shield configured to help filter or block damaging light or another curing stimulus coming from the curing stimulus assembly 129. The filtering element 180 substantially covers the gap between the curing stimulus portion 146 and the cap portion 124 when the curing stimulus positioning assembly 142 is in the first, deployed position, as shown in
In the alternative or in addition thereto, the filtering element 180 may comprise a magnifying glass for enlarging the view of the surface on which the curable formulation in being applied. Particularly in the application of nail polish, small details must sometimes be painted onto the fingernail of a user. In such a situation, the integrated magnifying glass can be used to enlarge the painting surface for detailed application. In a second, stowed position (not shown), the filtering element 180 is receivable within a light shield cavity (not shown) adjacent to the light portion cavity (not shown) in the cap portion 124. In that regard, the light portion cavity may simply be extended or enlarged to also receive the filtering element 180 when the curing stimulus positioning assembly 142 is in the second, stowed position against the cap portion 124. It should be appreciated that the filtering element 180 or similar may be used with any of the other embodiments shown and described herein.
Referring to
The curing applicator 210 similarly includes a curing stimulus positioning assembly 242 that is moveable between a first, deployed position, as shown in
In that regard, the curing stimulus positioning assembly 242 includes a curing stimulus portion 246 that houses a curing stimulus assembly (not shown), and first and second arms 250 and 254 extending from the curing stimulus portion 246 that are slidable within opposing grooves 264 and 268 defined along the side of the cap portion 224. Pin protrusions (not shown) or similar may be defined at the distal, interior end of each arm 250 and 254 that are selectively receivable within openings or notches (not labeled) defined at the ends of each groove 264 and 268.
To move the curing stimulus positioning assembly 242 into the first, deployed position, the first and second arms 250 and 254 are slid within the grooves 264 and 268 linearly away from the cap portion 224 until the pin protrusions are received within openings at the bottom end of the cap portion 224. Similarly, to move the curing stimulus positioning assembly 242 into the second, stowed position, the first and second arms 250 and 254 are slid within the grooves 264 and 268 linearly toward the cap portion 224 until the pin protrusions are received within openings at the top end of the cap portion 224. It should be appreciated that the arms 250 and 254 may be made from a suitably flexible material to allow the pin protrusions to move into and out of the openings in the cap portion 224 as the curing stimulus positioning assembly 242 is moved between the deployed and stowed positions.
The cap portion 224 includes a light portion cavity or recess 272 defined at a bottom of the cap portion 224 that is configured to receive the light portion 246 of the curing stimulus positioning assembly 242 when it is in the second, stowed position. In this manner, the curing stimulus positioning assembly 242 is stored compactly against the cap portion 224 when not in use such that the cap portion 224 may be secured on a container, such as a nail polish bottle, and such that the cap portion 224 is easily graspable by a user.
Referring to
In contrast to the curing applicators 10, 110, and 210 described above, the curing applicator 310 includes a curing stimulus positioning assembly 342 that is fixed in a first, deployed position, rather than being moveable between a first, deployed position and a second, stowed position. In that regard, the curing stimulus positioning assembly 342 includes first and second arms 350 and 354 fixedly secured to and extending from the cap portion 324. However, unlike the arms of the curing applicators 10, 110, and 210 described above, which are substantially linear, the first and second arms 350 and 354 have a bent or obtuse shape.
More specifically, the first and second arms 350 and 354 extend at least partially away from the central longitudinal axis of the cap portion 324 before extending downwardly toward the applicator tip 328. In this manner, the first and second arms 350 and 354 do not interfere with the container on which the cap portion 324 is secured when the curing applicator 310 is not in use. It should be appreciated that the first and second arms 350 and 354 may instead have any other suitable shape to accommodate containers (such as a nail polish bottle) having varying widths and cross-sectional shapes.
With the first and second arms 350 and 354 extending at least partially away from the central longitudinal axis of the cap portion 324, the curing stimulus portion 346 is necessarily positioned a bit further away from the applicator tip 328. To accommodate for this distance between the curing stimulus portion 346 and the applicator tip 328, the curing stimulus assembly 329 (which in an embodiment is a light assembly 330) may include an increased number of curing stimuli, such as LEDs (not labeled). It should be appreciated that any suitable combination of arm contour and curing stimulus arrangement, strength, type, etc., may be used to suit the desired curable formulation.
Referring to
The curing applicators 410 and 510 are generally configured to help prevent the curing stimulus from reaching the applicator tip 428 or 529, respectively, during application of the curable formulation to a surface. It can be appreciated that if curable formulation on the applicator tip is exposed to the curing stimulus, the curable formulation may at least partially cure on the applicator tip. By substantially preventing the curing stimulus from reaching the curable formulation on the applicator tip, the curable formulation will not cure until it is applied to a surface.
Similarly,
