Definitions
- Implementations described herein generally relate to a cosmetic applicator. More particularly, the present invention relates to an applicator suitable for applying mascara.
- Mascaras are generally used by consumers to accentuate the eyelashes by imparting color and/or aesthetic effects to the eyelashes.
- consumers use mascaras to darken, thicken, lengthen, and curl their lashes.
- the general purpose of a mascara applicator is to pick up a supply of mascara from a container, carry it from a reservoir of the container through a dosing or metering system, which is generally a wiper, without dripping, and apply it evenly to the eyelashes.
- Conventional mascara applicators generally include a brush attached to an elongated rod that is also connected to a handle.
- the brush and rod are usually housed in a cylindrical container, and the brush handle forms a closure for the container when the mascara applicator is not in use.
- the handle is pulled away from the container to remove the dosed mascara-laden brush.
- a wiper system removes excess mascara from the brush bristles, ideally leaving on the brush a level of mascara loading optimized for application.
- Conventional mascara applicators tend to focus on optimizing the mascara loading through a combination of brush design and wiper design.
- a non-conventional mascara applicator is disclosed in US Patent 8,360,673 B2.
- the applicator comprises a body.
- the body is comprised of a handle coupled to a piston rod which mates with a piston disposed within a product delivery chamber, and an applicator head.
- the applicator head contains a valve arrangement to permit flow of product into the product delivery chamber, but prevents backflow.
- the product is delivered to the lashes either by a plurality of prongs, each of which has a conduit that connects to the product delivery chamber, or through a single conduit between the product delivery chamber and the applicator head surface, wherein twisting of the handle delivers the product through the respective conduits.
- the foregoing non- conventional mascara applicator employs a biased valve that opens to deliver product to the conduits.
- biased valves containing a fluid within a reservoir generally remain closed unless the reservoir pressure is increased, whether by squeezing, pumping or other pressurization technique, until it reaches the valve’s threshold pressure. Once the valve’s threshold pressure is overcome, the fluid is so pressurized that it may flow out of the valve unpredictably or in excess of what is desired, until the pressure on the fluid drops below the valve’s threshold.
- Recent mascara formulations have been developed which expand or foam after application. Certain of these formulations may be stored in a pressurized canister with a propellant. Certain of these formulations may be stored at atmospheric pressure.
- the foaming formulations for mascara may have at least one surfactant, a solvent for the surfactant, and a volatile agent in an amount effective to swell the composition after application to the eyelashes. These foaming formulations further improve the aesthetic appearance of the eyelashes, which when applied foams or swells to a specified volume. A particular advantage is that one dose application may be sufficient to achieve the desired volume.
- conventional applicators are not well suited for storing or delivering these expanding and foaming mascara formulations.
- the mascara applicator assembly has a body.
- the body has an inner volume configured to accept mascara product.
- a stem is coupled to the body.
- the stem has a passage and one or more apertures.
- the one or more apertures extend through the stem and into the passage.
- a brush is disposed on a distal end of the stem and has a dispensing region and an application region.
- the dispensing region has bristle fibers arranged in an orientation different than the bristle fibers disposed in the application region.
- the dispensing region is positioned to receive product exiting the apertures.
- the mascara applicator assembly additionally has a cap.
- the cap comprises a cleaner configured to remove unused product from the brush when the brush is placed into or removed from the cap.
- the mascara applicator assembly has a body.
- the body has an inner volume configured to accept a mascara product container.
- An applicator has a stem having passage formed therethrough, one or more apertures formed through the stem and fluidly connecting with the passage, and a brush.
- the brush has a dispensing region and an application region.
- the dispensing region has bristle fibers arranged in an orientation different than the bristle fibers disposed in the application region.
- the dispensing region is positioned to receive product exiting the apertures.
- the mascara applicator assembly additionally has a cap.
- the cap comprises a cleaner configured to remove unused product from the brush when the brush is placed into or removed from the cap.
- the cleaner comprises one or more of the following elements selected from a wiper having one or more wiper blades, one or more waste chambers, a wiper sealing pad and a pin.
- the cap may be keyed to the base. In this manner, the cap aligns the cleaner therein with the brush so that the cleaner properly engages the brush and when present the wiper sealing pad aligns with the apertures thereby cleaning and sealing the apertures.
- the wiper sealing pad prevents contamination of the mascara product as well as clogging of the apertures.
- the pin may be aligned with the center of the stem when the brush is placed in the cap. In this manner, the pin may clean product from within the stem and prevent clogging of the stem and the apertures.
- a method for applying mascara with a mascara applicator. The method begins by dispensing mascara product from a container disposed in a mascara applicator assembly, flowing the mascara product through one or more apertures formed in the mascara applicator assembly into a dispensing region defined in a mascara brush, expanding the mascara product in a dispensing region of the mascara brush, and moving the foamed mascara to an application portion of the mascara brush.

- the mascara applicator assembly 100 has an overall length 102.
- the overall length 102 of the mascara applicator assembly 100 may be between about 135 mm and about 200 mm, such as about 182 mm.
- the mascara applicator assembly 100 may additionally have a diameter 124.
- the diameter 124 is selected to allow the base 1 10 to be comfortably held in the hand of the user, while also sufficiently sized to allow the base 1 10 to contain a reservoir of mascara and the mechanisms for delivering the mascara.
- FIG. 1 A cross-sectional schematic side view for the mascara applicator assembly 100 of Figure 1A depicted in Figure 2 and an exploded isometric side view for the mascara applicator assembly 100 of Figure 2 depicted in Figure 3.
- An applicator 250 extends from the base 1 10 and is selectively covered by the cap 120 when the cap 120 is affixed to the base 1 10.
- the cap 120 can be removed from the base 1 10 to expose the applicator 250.
- the applicator 250 is attached to the base 1 10 and receives mascara from a mascara product container 270 disposed in the base 1 10.
- the cap 120 is configured to enclose and protect the applicator 250 therein.
- the cap 120, applicator 250 and base 1 10 assemble together comprise the main portions of the mascara applicator assembly 100.
- the base 1 10 has a substantially tubular body 210.
- the tubular body 210 is cylindrical.
- An actuator 212 is disposed at a first end 213 of the tubular body 210.
- a top 216 is disposed at a second end 21 1 of the tubular body 210.
- the top 216, tubular body 210 and actuator 212 bound an inner volume 218 defined within the base 1 10.
- the inner volume 218 is sized to accept the product container 270 and a cam platform 214 therein.
- the cam platform 214 is disposed between the actuator 212 and the product container 270.
- the cam platform 214 is moveable between a first position and a second position in axial direction defined by the tubular body 210.
- the first position of the cam platform 214 is closer to the actuator 212 relative to the second position.
- the cam platform 214 is shaped to fit and rotate in the inner volume 218.
- the cam platform 214 may have a circular shape mirroring the shape of the inner volume 218 such that rotation can occur without interference from the tubular body 210.
- the cam platform 214 has a movement mechanism 234.
- the movement mechanism 234 is configured to engage a corresponding drive mechanism 238 of the actuator 212.
- the actuator 212 has a fastener 236 which engages the tubular body 210 to hold the actuator 212 at the first end 213 of the tubular body 210, while allowing the actuator 212 to rotate.
- the fastener 236 includes a snap-fit groove or protrusion which engages a complimentary groove or protrusion of the tubular body 210 to axially retain the actuator 212 to the tubular body 210 while allowing rotation of the actuator 212 relative to the tubular body 210.
- the movement mechanism 234 is a saw-tooth gear that engages a complimentary saw-tooth gear of drive mechanism 238.
- the fit and angle of the drive mechanism 238 and movement mechanism 234 biases the cam platform 214 to be in the first position that is near the actuator 212.
- Rotation of the actuator 212 in one direction causes the saw-tooth gear of the drive mechanism 238 to ride against the saw tooth gear of the cam platform 214, and on crest of each tooth of the gear, move the cam platform 214 upwards to the second position that is farther from the actuator 212 until the crests of the teeth in the saw-tooth gears pass each other, allowing the cam platform 214 to return to the first position closer to the actuator 212.
- the rotation of the actuator 212 causes the cam platform 214 to rise and fall, thus displacing the product container 270 up and down in an axial direction relative to the tubular body 210.
- the product container 270 contains the mascara formulation under pressure and an aerosol propellant.
- the product container 270 includes a valve 271 that, in a closed state, retains the mascara formulation and aerosol propellant within the container 270.
- the product container 270 may be of a variety shapes and materials suitable for retaining the mascara formulation and aerosol propellant.
- the valve 271 is operable between an open and closed position in response to axial displacement of the valve 271 relative to the product container 270. Alternately, the valve may operate between the open and closed position in response to a twisting displacement of the valve 271 relative to the product container 270.
- the valve 271 is generally in a normally closed positon.
- the valve 271 of the product container 270 is configured to release the product, e.g., the mascara formulation, contained under pressure within the product container 270.
- the product container 270 may be configured to maintain the mascara product separate from the propellant by means of a bag, diaphragm or piston inside the product container 270.
- the mascara product is a post-foaming composition which does not create foam as it is immediately dispensed from the product container 270, but foams after exposure for at least 2 seconds to atmospheric pressure.
- the product container 270 is a bag on valve which keeps the propellant separate from the mascara product. Displacement of the product container 270 upward within the base 1 10 by the rotation of the actuator 212 while the valve 271 is held stationary relative to the base 1 10 causes the valve 271 to change to the open state and allow the product to dispense from the container 270 through the valve 271. As the product container 270 returns downward by action of the actuator 212, the valve 271 moves away from the container 270 and returns to the closed state, thus sealing the product within the product container 270 and stopping the dispense of product through the valve 271.
- the length of upward movement may be altered or adjusted by changing the height of the teeth, the at displacement of the cam platform 214 from the actuator 212, or by other techniques suitable to adjust the duration that the valve 271 is in the open state, and thus, control the dosing of product from the product container 270.
- the operation of the actuator 212 and dispensing of the product from the product container 270 may alternately be performed by other mechanisms.
- the product container 270 may be a bag and the actuator 212 may utilize a screw to elevate the cam platform 214 as a piston to force product from the product container 270 through the valve 271.
- the actuator 212 may be biased to return to the at rest position where the valve is in a closed state and movement of the actuator 212 by twisting, or pushing much the same way a retractable pen functions, may cause the valve 271 in the product container 270 to dose a pre-measured or otherwise limited portion of the product.
- the product container 270 may be a bag containing non-pressurized or non-foaming formulations and the tubular body 210 may be malleable to permit the product container 270 to be squeezed through the tubular body 210 or the tubular body 210 may be the product container 270 and squeezing the tubular body 210 dispenses the product from the product container 270.
- the product container 270 and the tubular body 210 are one and the same squeeze tube and product is squeezed therefrom in a fashion similar to a toothpaste tube.
- the tubular body 210 may be cylindrical, oblong or other suitable shape for squeezing and may additionally retain a deformed, i.e., squeezed, shape post squeeze.
- the applicator 250 includes a rod 354, a stem 352 and a brush 260.
- the brush 260 is coupled to a first end 410 of the stem 352.
- the rod 354 is disposed at a second end 412 of the stem 352. Additional details of the applicator 250 will be discussed below with additional reference to Figures 4 and 5.
