[Brief explanation of the drawing]

[0008] Many of the above-described aspects and associated advantages of the present invention will become more readily apparent as the following embodiments for carrying out the invention become more clearly understood in conjunction with the accompanying drawings.

[0009] [Figure 1] Figure 1A shows an exemplary applicator related to this technology.

[0010] Figure 1B is a cross-sectional view of the exemplary applicator shown in Figure 1A, relating to this technology.

[0011] [Figure 2] Figure 2 shows an exemplary system relating to this technology, including a dispensing device 200 to which an exemplary applicator 100 is attached.

[0012] [Figure 3]Figure 3 shows an example of how to use the skincare system related to this technology. [Modes for carrying out the invention]

[0013] While exemplary embodiments have been illustrated and described, it should be understood that various modifications can be made to these exemplary embodiments without departing from the spirit and scope of the present invention.

[0014] This specification describes an applicator having a non-contact piston for dispensing and applying a formulation to a surface using a rollerball. In some embodiments, the applicator also includes a mechanism for accurately detecting how much product is in the applicator.

[0015] In some embodiments, the applicator is configured to be attached to a dispensing device. In some embodiments, the dispensing device is configured to administer phototherapy while applying the formulation.

[0016] Figure 1A shows an exemplary applicator relating to the present technology. The applicator 100 may include a rollerball 110 and an attachment 120.

[0017] The rollerball 110 may be configured to dispense and apply the formulation placed in the reservoir within the applicator 100 (as shown in Figure 1B). In some embodiments, the rollerball 110 is made of plastic, but in other embodiments, the rollerball 110 may be made of glass or metal.

[0018] In some embodiments, the applicator 100 also includes an attachment 120 configured to secure the applicator 100 to a dispensing device, such as the dispensing device 200 in Figure 2. While the attachment 120 is illustrated as one or more tabs for coupling to the dispensing device, the attachment 120 can take any form that allows the applicator to be secured to the dispensing device, including a threaded attachment, a magnet, or an attachment configured to snap or slide onto the dispensing device. In some embodiments, the attachment 120 is transparent so that the dispensing device is visible through the attachment.

[0019] During operation, the applicator 100 can be placed inside the dispensing device (as shown in Figure 2) and secured to the dispensing device with the attachment 120. The rollerball 110 can be rolled over a surface such as the user's skin to apply the formulation.

[0020] Figure 1B is a cross-sectional view of the applicator shown in Figure 1A relating to the present technology. The applicator 100 may include a rollerball 110, a reservoir 130 configured to hold a formulation 140, a piston 150, a non-contact tip 160, a piston magnet 170, and one or more magnets 180a, 180b, 180c.

[0021] In some embodiments, the reservoir 130 is located inside the applicator 100 and is configured to hold the formulation 140. In some embodiments, the formulation 140 is a skincare formulation. In some embodiments, the skincare formulation is a cosmetic such as a moisturizer, lotion, acne treatment, wrinkle or fine line treatment, or foundation or concealer. As the rollerball 110 rolls, the formulation 140 from the reservoir 130 is applied to the surface.

[0022] In some embodiments, the applicator 100 further includes a piston 150 configured to push the formulation 140 toward the rollerball 110 when the formulation is applied. In some embodiments, the piston 150 is instructed to push the formulation 140 toward the rollerball 110 by the circuitry of a dispensing device (such as the dispensing device 200 in Figure 2) or by the circuitry of the applicator itself.

[0023] In some embodiments, the piston 150 is driven upward by a piston magnet 170. The piston magnet 170 may be located below the piston 150. The piston 150 can be pushed up by the piston magnet 170 in response to a magnetic field. In some embodiments, the piston magnet 170 and the piston 150 are two separate parts, while in other embodiments, the piston magnet 170 and the piston 150 are a single part. In some embodiments, the piston magnet 170 is located inside the piston 150. In some embodiments, the piston 150 is made of plastic and encloses the piston magnet 170. In some embodiments, the piston magnet 170 is not removable. In some embodiments, the piston 150 can be precisely positioned for better control.

[0024] In some embodiments, the applicator 100 includes one or more magnets 180a, 180b, 180c for generating a magnetic field. In some embodiments, the one or more magnets 180a, 180b, 180c are the first magnet 180a, the second magnet 180b, and the third magnet 180c. As shown, in some embodiments, the first magnet 180a is parallel to the piston magnet 170. In some embodiments, the second magnet 180b is disposed at an angle of 45 degrees to the right of the first magnet 180a, and the third magnet 180c is disposed at an angle of 45 degrees to the left of the first magnet 180a. Although this configuration is shown, it should be understood that the one or more magnets 180a, 180b, 180c can take any configuration that generates a magnetic field. The one or more magnets 180a, 180b, 180c are shown as being inside the applicator, but in some embodiments, the one or more magnets 180a, 180b, 180c are inside a dispensing device such as the dispensing device 200 of FIG. 2.

[0025] In some embodiments, the applicator 100 includes a non-contact chip 160 configured to cause a dispensing device to identify the type of formulation 140 inside the applicator 100. Using the non-contact chip 160, any number of things related to the formulation 140 or the applicator 100 can be identified. What can be identified includes the amount of the formulation 140 inside the applicator 100, the expiration date of the formulation 140 inside the applicator 100, or when to replace the applicator 100.

[0026] In some embodiments, the applicator 100 further includes mechanisms 190, 195 for measuring how much formulation 140 is in reservoir 130. In some embodiments, the mechanisms include a ToF (time of flight) sensor 190 and a mirror coating 195 within reservoir 130. In some embodiments, the ToF sensor 190 is disposed inside the applicator 100, although the ToF sensor 190 may also be disposed inside a dispensing device (such as dispensing device 200 of FIG. 2).

[0027] In operation, the ToF sensor 190 is configured to emit the LED light shown by the dashed line. The mirror coating 195 is configured so that the LED light is reflected to the ToF sensor 190. The ToF sensor 190 is shown to be directly below the mirror coating 195, although in some embodiments, the ToF sensor may be spaced apart from the mirror coating 195. In such a case, one or more reflectors (not shown in FIG. 1B) cause the emitted LED to be reflected to the mirror coating 195 and back to the ToF sensor 190.

[0028] FIG. 2 is an exemplary system including a dispensing device 200 to which an exemplary applicator 100 according to the present technology is attached. In some embodiments, the applicator 100 can be attached to the dispensing device 200. In some embodiments, the dispensing device includes an end 210, one or more light sources 220a, 220b, an actuator 230, and a contactless reader 240. In some embodiments, the applicator 100 is connected to the dispenser 200.

[0029] In some embodiments, the dispensing device 200 includes an end 210. The end 210 may be configured to be visible through an attachment 120 on the applicator 100. In some embodiments, the base 210 includes one or more light sources 220a, 220b configured to provide a phototreatment to the surface while the formulation is being applied.

[0030] In some embodiments, one or more light sources 220a, 220b are LEDs. In some embodiments, the dispensing device has only two light sources 220a, 220b. In some embodiments, the first light source 220a is configured to provide phototherapy at a first wavelength. In some embodiments, the second light source 220b is configured to provide phototherapy at a second wavelength. In some embodiments, phototherapy at the first wavelength and phototherapy at the second wavelength are performed simultaneously. In some embodiments, phototherapy and application of the formulation are performed simultaneously.

[0031] In some embodiments, the dispensing device 200 includes one or more actuators 230. Although the actuators 230 are illustrated as buttons, in some embodiments the actuators may be switches, capacitive touch buttons, dials, etc. The actuators may be configured to initiate the application of phototherapy, to apply the formulation, or to do both.

[0032] In some embodiments, the dispensing device 200 also includes a contactless chip reader 240 for reading the contactless chip 160 on the applicator 100.

[0033] During operation, the user can place the applicator 100 into the dispensing device 200. When the actuator 230 is activated, the formulation is applied, phototherapy is administered, or both are performed simultaneously. The user can then apply the formulation with the applicator 100.

[0034] Figure 3 shows an example of a method 300 using the skincare system related to this technology.

[0035] In block 310, the applicator is attached to the dispensing device. In some embodiments, the applicator slides into the dispensing device. In some embodiments, the applicator clicks into place inside the dispensing device. In some embodiments, the applicator is secured to the dispensing device through snaps, tabs, or magnets.

[0036] Optionally, in block 320, a contactless reader on the dispensing device identifies the formulation inside the applicator using a contactless tip on the applicator. In some embodiments, the contactless tip may also identify the amount of formulation inside the applicator or whether the applicator needs to be replaced.

[0037] In block 330, a magnetic field is generated, moving the piston magnet and thereby the piston to the top of the reservoir, pushing the formulation toward the rollerball. In some embodiments, the magnetic field is generated by one or more magnets inside the applicator. In some embodiments, the magnetic field may be generated by a dispensing device. In some embodiments, the magnetic field is generated by first, second, and third magnets. When the magnetic field is generated, the piston magnet pushes the piston, moving the formulation toward the rollerball.

[0038] In block 340, the formulation is dispensed as the piston pushes up the reservoir. As the piston is pushed up, the formulation is pushed towards the rollerball.

[0039] In block 350, the dispensing device performs a phototherapy. In some embodiments, the dispensing device performs the phototherapy using one or more light sources. In some embodiments, the dispensing device may be configured to perform one or more phototherapys. In some embodiments, one or more light sources on the dispensing device are configured to perform a first phototherapy at a first wavelength, and one or more light sources are configured to perform a second phototherapy at a second wavelength. In some embodiments, the first and second phototherapys are performed sequentially, while in other embodiments, the first and second phototherapys are performed simultaneously.

[0040] In block 360, the rollerball is rolled over a surface such as the user's skin, and the formulation is applied to the surface. In some embodiments, steps 330 to 360 are all performed simultaneously.

[0041] The method ends at block 370.
