DETAILED DESCRIPTION OF THE INVENTION

[0035] In the drawings, like numerals indicate like elements throughout. Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. The following describes preferred embodiments of the present invention. However, it should be understood, based on this disclosure, that the invention is not limited by the preferred embodiments described herein.

Adjusting a Cosmetic Applicator Without any Mechanisms

[0036] A cosmetic applicator has an applicator region, which can be adjusted to any desired angles off a longitudinal axis of a brush in any direction around an axis. The applicator region is joined at the end to an applicator stem by a ball joint connection, where the user pivots the applicator region to a desired angle. Unlike conventional ball-joints, where a pivot angle about the axis is limited, the applicator's ball-joint is designed to have a greater range of angular adjustments.

[0037] The applicator region pivots at an angle of up to 90 around its axis in order for the user to apply composition while holding the applicator at its grip in an orientation that is more natural and ergonomic to the wrist of the user.

[0038] FIGS. 1-4 show various components of a cosmetic applicator 1 with a preferred design. FIG. 1 shows that the applicator region 2 pivots at an angle of up to 90 around its axis 3 with an interval of 30. However, this interval is not limited to these angles. The interval can be designed with any desired angles. In addition, FIG. 2 shows that an eye 4 of the cosmetic applicator has multiple slots 5 along petals 6 of the eye. These slots can be designed such that the applicator region pivots and positions stably at the desired interval (angles). For example, each of angles X, Y, and Z can be 30, as shown in FIG. 1. However, these angles are not limited to 30. In addition, the number of slots is not limited to three, as shown in FIG. 2. These slots can be made of any materials, such as rubber, and designed with any shapes, that can hold the applicator region stably and can be moved to the next slot easily by the user. FIG. 3 shows a ball stud 7 and a stopper 8 of the cosmetic applicator. Here, the stopper is used for the user to insert the applicator region (brush) easily into the mascara case 10 by having the stopper be inserted into a hole 9 shown in FIG. 4. That is, the stopper A enables the user to have the handle and the brush (applicator region) arranged in a straight line, as shown in FIG. 36. In FIG. 36, the arrow shows the stopper formed on the ball stud, which is inserted to the hole. However, the hole can be formed on the ball stud, and a protrusion (stopper) can be formed inside the eye. The magnetic force can be used to attract the stopper into the hole so that the user can easily straighten the handle and the brush, as shown in FIG. 37. In FIG. 37, a metallic material is inserted inside the ball stud (B), and a magnetic material is inserted inside the eye (C) or vice versa. Finally, a circular indentation/protrusion D can be formed around the ball stud in addition to the stopper, as shown in FIG. 38, so that the handle and the brush can be straightened easily by the user.

[0039] Referring to FIG. 8, the cosmetic applicator has a socket, which retains a ball-stud having a depth that is less than that of a hemisphere. A brim of walls of the semi-hemisphere rises up to (and supports) a neck of the applicator region, when the axis of the applicator region is perpendicular to that of the holder shaft.

[0040] To physically constrain the ball-stud within the socket, the cosmetic applicator has an upper portion, which resembles the shape of petals or leaves of a flower. These petals, having a radial symmetry around the axis, sit at the brim of the lower semi-hemisphere, giving the socket the shape of a hollow inner sphere. The edges of these petals guide the neck of the applicator region, when a pivot moment is applied, guiding a stopper of the ball-stud to follow along in channeled grooves along the inner walls of the socket.

[0041] The cosmetic applicator has five sectional petals protruding from the brim of the lower semi-hemisphere to retain the ball-stud within the socket. Five open sections allow the applicator region to pivot in a direction around the axis in 72 segments while being guided by the petals and the channeled pathways. This preferred method allows the user to adjust the applicator region to their discretion in any direction around the axis of the applicator without the concern of which correct orientation the applicator needs to be in prior to adjustments.

[0042] The cosmetic applicator has the ball-stud, which has the shape of a polygonal sphere and the socket taking shape that is consistent with it. Each face of the polygonal sphere fixes in position to the pivot angle (i.e., octagon will have angular adjustments in increments of 45).

[0043] In order to hold the applicator region to each angular position about the longitudinal axis of the applicator, the ball-stud stopper works in conjunction with the cavities or ridges that are placed along the grooves of the inner walls of the socket. Ridges or cavities are placed in increments to fix the applicator region to each angle ranging from 0 (up-right) to 90 (bent) until a breakaway moment is applied by the user. Breakaway moment shall be no greater than the force applied by the simple flick of the user's wrist. This is because a great amount of holding force is unnecessary due to the nature what the applicator is used for, namely, mascara composition applied to the eyelashes.

[0044] Referring to FIG. 13, the cosmetic applicator has a dual ball joint movement, which works independently to each other and each with its own limitations. A connector arm with ball-studs at each end is a connecting point of the applicator region to the holder shaft. The holder shaft is similar to above embodiments with a grip and socket opposite to the end of grip. The holder shaft socket has a cavity, whose depth is greater than that of a hemisphere. The socket seats the ball-stud (lower joint) within its cavity and constrains the ball-stud within its pocket. Limitations of cone axis (pivot angle off longitudinal axis of applicator) of each ball joint may have a difference, but the combined pivot angle of applicator region to holder shaft shall be no greater nor less than perpendicular (90).

[0045] Second ball-joint (upper joint) at the opposite end to holder shaft ball-joint has a size and/or shape that may differ. Ball-joint attaches to socket of applicator region, in which applicator region has a means of securing to the socket. Socket has a depth, which is greater to that of a hemisphere and constrains the ball-stud within its cavity.

[0046] Similar to the above embodiments, the ball-studs at each end of the connector arm has a stopper or protrusion that functions to hold the position of the ball stud until a breakaway moment is applied. However, a guide is not necessary, as the ball-joint has more degrees of freedom in each plane when compared with the previous embodiments. The stopper of each ball-stud fits in one of the many dimples or cavities arranged along the walls of the each respective socket. Dimples are arranged to have radial symmetry around the axis of the socket, providing the joint with a diverse set of holding positions.

[0047] For an adjustable brush fixed to the end of a cosmetic wand where the user makes adjustments using the container, the brush can be plastic injected, nylon twist, or mono/bi-injection molded.

[0048] The mascara brush consists of a brush shaft, a ball stud or sphere, a shaft anchor, a holder assembly (shaft), and a seal.

[0049] The brush shaft is fixed to the ball stud using the shaft anchor. The shaft anchor may or may not be used. There are other ways of fixing the brush shaft onto the ball stud. For the brush shaft or brush, the brush may be injection molded or nylon twist or molded twist. The brush shaft may be a twisted metal core or polymer shaft. The brush shaft has projections encompassing the core (bristles) of nylon or polymer.

[0050] Referring to FIG. 9, the ball stud or sphere is connected to the holder shaft via ball-joint. The ball stud may or may not be a sphere, as it may take form of other shapes as well. The ball stud has protrusion(s) or stopper at the opposite end to where the brush shaft securely fits to. The stopper works in conjunction with grooved pathway and cavities along the wall of joint-socket or eye.

[0051] Referring to FIG. 10, the holder shaft may or may not be an assembly. It takes in form of a mascara applicator, which includes a grip and a shaft that extends from the grip. A socket or eye at the end of shaft attached to the grip allows the ball stud to be securely pocketed and allows for a smooth transition of adjustments.

[0052] Referring to FIG. 14, the eye acts as a socket for the ball stud to fit securely into and allows adjustments to be made in any direction similar in functionality to a ball-joint. Unlike ball-joints that are limited in their range of adjustments, the eye and ball stud connection allows movements to be made in a greater range of adjustments in all directions around the axis.

[0053] The eye may or may not be a part to the assembly to the holder shaft (assembly). The eye may be made of polymer, metal, and etc. The eye may have a shape that is consistent to the shape of ball stud and fit the ball stud securely to the holder (assembly). The eye has sides or curves consistent with that of ball stud. (i.e., a spherical ball stud has an eye of a hollow sphere.)

[0054] The size of ball stud to size of the interior walls of the eye may or may not be of similar sizes; there may be a slight offset. (i.e., a radius of ball stud to radius of inner walls of socket may have offset.)

[0055] Referring to FIG. 11, the eye socket may have walls of different thicknesses covering the ball stud at different heights around the ball. The eye socket may fully or partially encompass the radius of ball and at different thicknesses. The eye's inner radius may have an offset in accordance with radius of spherical ball stud. This allows for tolerance and fitting of seal. The eye has petals that reach over the seated ball-stud to constrain the ball-stud within the socket and has edges, which guide the neck of the brush stem during adjustments.

[0056] Referring to FIG. 12, the eye has channeled pathways molded or cut into the inner concavity of the eye. These channels, in conjunction with the petal edges, provide a guide for the stopper during transition, allowing the user to smoothly adjust the angle. Grooves also have smaller cavities or pockets that fixate the pivot angle of the brush at any longitudinal direction. There may be multiple set of cavities for each direction.

[0057] The eye may or may not have channeled pathways, but has a method to allow smooth pivotal transitions of the brush similar to a ball joint and will not have any angular limitations or restrictions.

[0058] The eye houses the ball stud and secures it either by securing the ball stud within its cavity as a socket or by magnets (magnetic force), brackets, or grooves.

[0059] The eye has a method to fix brush angle at user discretion in all set or in all directions and in set or in all angles. In addition, the eye may have thin walls with wedged sections encircling the brim of the hollow half sphere that concave inwards to form a hollow sphere socket. Wedges function to retain the ball stud within the cavity when in motion.

[0060] The eye may have slots along the wall of the socket to allow the brush to be angled up to (but not limited to) 90. In addition, the eye may or may not have a seal made of rubber, silicone, plastic, and etc.

[0061] FIG. 19 shows one example of the cosmetic applicator without mechanisms (sphere part).

[0062] FIG. 20 shows one example of the cosmetic applicator without mechanisms (holder part).

[0063] FIG. 21 shows one example of the cosmetic applicator without mechanisms (top part).

[0064] FIGS. 28-33 show various parts of the cosmetic applicators with different designs.

[0065] FIGS. 34(a)-(c) show various parts of the cosmetic applicators with a preferred design.

[0066] FIG. 34(a) shows a rod portion, FIG. 34(b) shows a sphere portion, and FIG. 34(c) shows a top portion.

[0067] FIG. 35 shows another example of the cosmetic applicator with a preferred design.

Adjusting a Cosmetic Applicator with any Mechanisms

[0068] A cosmetic applicator has an applicator region, which can be adjusted to any desired angle off a longitudinal axis of a brush in any direction around an axis with mechanisms.

[0069] Referring to FIG. 15, the user pushes button situated at the end of the holder to retract a locking pin on top, holding the brush position in place. Once button is depressed, the locking pin retracts into the holder stem, allowing the use to apply moment to the brush to a desired angle.

[0070] Referring to FIG. 16, the user pulls the knob situated at the bottom end of the holder, which in turn retracts the locking pin into the holder stem. Once locking pin is retracted, a moment force may be applied by the user to adjust the brush position to a desired angle.

[0071] Referring to FIG. 17, the user twists the knob situated at the end of the holder to retract the locking pin into the holder stem. Once locking pin is retracted releasing the angular position of the brush, the user may apply a moment force to the brush to adjust the position to a new desired angle.

[0072] FIG. 18 shows one example of the cosmetic applicator with mechanisms.

[0073] FIGS. 22-27 show various parts of one example of the cosmetic applicator with mechanism.

[0074] Accordingly, it will be recognized by those skilled in the art that changes or modifications may be made to the above-described embodiments without departing from the broad inventive concepts of the invention. It should therefore be understood that this invention is not limited to the particular embodiments described herein, but is intended to include all changes and modifications that are within the scope and spirit of the invention as defined in the claims.

Advantageous Effect of the Present Invention

[0075] FIGS. 1-35 show various example of a cosmetic applicator, which is adjustable by means of an articulation, described in the present invention.

[0076] The advantages of the present invention will be apparent to those skilled in the art from the foregoing specification.

[0077] For example, the users can apply mascara in an orientation that is more ergonomic at their desired angles with or without any mechanisms. The users also can use the entire surface of brush (360) when applying the mascara. The users' arm does not have to be raised her shoulder's height to make the brush located in parallel with her eyelashes, causing her make-up operation to be performed in a very stable posture and resulting in excellent make-up at her desired facial locations. After the users are finished with applying the mascara, the users can easily insert the brush into the mascara case.

[0078] The cosmetic applicator is not limited to mascara. The cosmetic applicator of the present invention can be extended to eyeliner, blusher, eyeshadow, lip gloss, and etc.
