Description

Method of making an applicator with precision eye opening

Technical Field

The present disclosure relates to a mask having custom openings and a method of forming a mask having custom openings defined therein.

Background

Agents for influencing the structure of interest are well known. The temperature effects may be induced by the application of hot or cold agents to the target. The appearance of the target may be affected by both the cosmetic and decorative agents. The electric current, voltage, and electric and magnetic fields may be applied to the target using a topical applicator. For biological targets, surface properties can be affected by topical application of moisturizers, drugs, and other treatment actives.

The effectiveness of an active agent may be affected by the nature of the applicator that may be used to facilitate the interaction of the active agent with the target structure. Typical applicators are less accurate in their conformability to the target structure and use of only one size or a few sizes for all tend to compromise the actual performance of the active agent. In particular, conventional universal applicators for facial products, for example, typically have generally large eye and lip openings to accommodate differences in the user's features. Thus, such applicators are ineffective in applying active agents in the area of the eyes or lips of many individuals. In addition, given the generally poor fit and registration of conventional applicators on the face, alignment of the ocular and lip openings can be particularly difficult and result in discomfort to the user.

Disclosure of Invention

According to embodiments, applicators having custom sized openings and methods of making the same may include applicators having agents for affecting a target structure, such as cosmetic masks.

According to an embodiment, a method of preparing a mask for a face of a human user may include determining an eye region lower boundary. For example, the ocular region lower boundary may be determined by locating one or more of a minimum of one or more lower lashes of the at least one eye when the eye is open, a lower boundary of the eyeball determined by a peak point of a concave arc in a lower eyelid of the at least one eye when the eye is closed, and a minimum of one or more upper lashes of the at least one eye when the eye is closed. The method may further include determining an upper boundary of the ocular region. For example, the upper boundary of the ocular region may be determined by locating the upper boundary of the eyeball, which is determined by the peak point of the concave arc in the upper eyelid region of at least one eye when the eye is closed. The eye height is defined by the distance between the lower boundary of the eye region and the upper boundary of the eye region. The method further includes defining at least one eye opening such that when the mask is applied to the face, the first edge is disposed 0mm to about 10mm below the lower boundary of the eye region and the second edge is disposed 0mm to about 10mm above the upper boundary of the eye region. The method may further include forming a mask having at least one eye opening.

Detailed Description

In one aspect, the mask includes at least one opening having a shape determined from a digital geometric representation of the target structure or other created digital geometric representation.

As used herein, the term "flexible" means that the three-dimensional geometry of the element or the applicator as a whole can be altered without any permanent deformation of the element geometry occurring. The applicator may also be used interchangeably herein with "mask".

Referring to fig. 1A-1C, an eye region 10 of a human face includes an eyeball 12 partially covered on the bottom by a lower eyelid 14 and partially covered on the top by an upper eyelid 16. The lower eyelid 14 and the upper eyelid 16 each have an inner eyelid liner 18, 20 adjacent the eyeball 12. The lower and upper lashes 22, 24 extend from the eyelid liners 18, 20. Ocular region 10 also includes a medial canthus 26 and a lateral canthus 28. The eyebrow 30 is positioned above the upper eyelid 16.

The boundaries of the eyeball 12 may be visually determined outside the upper eyelid 14 and the lower eyelid 16. Referring to fig. 1A and 1C, the lower boundary of the eyeball 12 is set at the peak point 32 of the concave arc 32 in the lower eyelid 14. Referring to fig. 1B and 1C, the upper boundary of the eyeball 12 is disposed at the peak 34 of the concave arc 34 in the upper eyelid 16. Fig. 1D is a side view showing the depressions in the upper eyelid 14 and the lower eyelid 16 formed by the boundaries of the eyeball 12.

As used herein, "eye height H _E" refers to the maximum distance between the lower eye region boundary 66 and the upper eye region boundary 68.

Referring to fig. 2, the nose region 36 may include a central nose tip 38, a first nostril 40 and a second nostril 42, and a columella separating the first nostril 40 and the second nostril 42. The first nostril 40 and the second nostril 42 are each defined by an outer nostril wall 46, 48 and are defined internally by a nostril post. The columella nasi ends in a base 44.

Referring to fig. 3, the mouth region 50 includes an upper lip 52 and a lower lip 54 bounded on their outer periphery by a lip red 56. The lip red has a highest point 58 in the upper lip 52 and a lowest point 60 in the lower lip 54. The mouth region 50 also includes a first corner 62 and a second corner 64 of the mouth.

Referring to fig. 14, a conventional mask 200 is generally a flat two-dimensional mask 200 having generic eye openings 202 and spacing. Such masks 200 also typically have universal openings for the mouth 204 and nostrils 206. When worn, the conventional mask 200 does not align well with the eyes and other features of many users' faces. In the case of an ocular region, such conventional non-conforming masks 200 may cause discomfort by resting on the eye or covering the eye and/or causing ineffective treatment because the opening is overlying the under-eye region to be treated, rather than the surface of the mask with active, cosmetic and/or therapeutic agents. Similarly, in the mouth region, an unfinished mask 200 may overlap the lip region or be spaced too far from its lip or nose portion. In this region, the non-conforming mask 200 may interfere with or overlap the nostrils. Methods according to various embodiments of the present disclosure advantageously provide custom fit openings that may allow the mask 200 to be properly aligned, for example, in the eye region, resulting in improved comfort and fit.

Referring to fig. 6, according to an embodiment, a method according to embodiments of the present disclosure may provide a mask 100 having an eye opening 102 that may have a lower peripheral edge, a first edge 104, of the inner eyelid liner 18 proximate to the lower eyelid 14 of a user, thereby achieving improved coverage of the under-eye area by the portion of the mask 100 on which active, cosmetic and/or therapeutic agents are disposed. According to other or additional embodiments, a method according to the present disclosure may provide mask 100 with a pair of eye openings 102 that are spaced apart such that each opening is located at a desired, proximate, but non-overlapping location from medial canthus 26. According to other or additional embodiments, methods according to the present disclosure may provide a mask 100 having nasal openings 114 that partially overlap the outer nostril walls 46, 48, but do not interfere with the nostrils 40, 42 or cause discomfort when breathing. According to other or additional embodiments, methods according to the present disclosure may provide a mask 100 having mouth openings 124 that are spaced apart proximate to the lip red 56 of both the upper lip 52 and the lower lip 54. According to embodiments of the present disclosure, the mask and methods of making the same may include any combination of custom defined openings and/or standard sized (universally suitable) openings. For example, the mask may include custom defined mouth openings and standard sized eye openings according to embodiments of the present disclosure. For example, the mask may include custom defined eye openings and standard sized nose and/or mouth openings according to embodiments of the present disclosure. For example, the mask may include a custom defined nasal opening according to embodiments of the present disclosure, without an opening for the eyes or mouth. For example, the mask may include custom defined eye, mouth, and nose openings according to embodiments of the present disclosure. Any other such combination defining an opening is contemplated herein.

Methods and masks 100 according to embodiments of the present disclosure provide improved fit and comfort. The improved fit may allow for better contact of the active, cosmetic and/or therapeutic agents on the mask 100 with the desired area of the face. The desired area may include, for example, one or more of the under-the-eye area, the corners of the nose 45 outboard of the outer nostril walls 46, 48, and the skin adjacent the lips. Improved fit may include the mask 100 covering such desired areas without giving up coverage over other areas such as the eyes and/or without interfering with facial features such as the eyeball 12, nostrils 40, 42 and/or lips 52, 54 that should be avoided from being covered. The mask 100 according to embodiments of the present disclosure may also have improved fit, not only in contact with the desired area, but also maintain a tighter contact without gaps or bubbles in the mask 100 that would interrupt contact with the desired area.

Referring to fig. 4, a method of preparing a mask 100 for a face, according to an embodiment of the present disclosure, includes determining an eye region lower boundary 66, determining an eye region upper boundary 68, disposing a first anchor point 0mm to 10mm below the eye region lower boundary 66 and a second anchor point 0mm to 10mm above the eye region upper boundary 68, and defining at least one eye opening 102 for the mask 100, the eye opening having a first edge intersecting the first anchor point and a second edge intersecting the second anchor point. As used herein, an anchor point is a digital reference point that is a fixed point in space and is selected on a digital representation of a target area.

A method of preparing a mask 100 for a face, in accordance with an embodiment of the present disclosure, includes determining an eye region lower boundary 66; determining an upper ocular region boundary 68 by locating an upper boundary of the eyeball 12; and defines at least one eye opening 102 such that when the mask 100 is applied to the face, the first edge 104 is disposed 0mm to about 10mm below the lower eye region boundary 66 and the second edge 106 is disposed 0mm to about 10mm above the upper eye region boundary 68. The method may further include forming a mask 100 having at least one eye opening 102. The ocular openings may be the same, similar, or significantly different from one another to accommodate both eyes of a particular individual.

In any of the embodiments herein, the upper ocular region boundary 68 may be one or more of the following: peak points 34 of concave arcs in the upper eyelid 16 of at least one eye when the eyes are closed; peak points of fold lines in the upper eyelid; the highest point of the upper eyelashes 24 when the eyes are open; and the edge of the upper eyelid. The highest point of the upper lashes may be selected in embodiments as the average highest point in a group or all of the upper lashes when the eyes are open, or may be the highest point of the longest upper lashes.

In any of the embodiments herein, the ocular region lower boundary 66 may be determined by locating the position of one or more of the minimum of the one or more lower lashes 22 of the at least one eye when the eye is open, the lower boundary of the eyeball 12 determined by the peak point 32 of the concave arc in the lower eyelid 14 of the at least one eye when the eye is closed, the edge of the eyeball on the underside, the edge of the lower eyelid, and the minimum of the one or more upper lashes 24 of the at least one eye when the eye is closed.

In any of the embodiments herein, the forming of the mask 100 may include exporting data related to the defined at least one ocular opening 102 to a cutting tool to define a cutting path for cutting the ocular opening 102 into the mask 100 base. Alternatively, the forming of the mask 100 may include combining digital data related to the defined at least one eye opening 102 with digital data associated with the shape of the mask 100 to be defined in the digital data of the mask 100 having the eye opening 102, which combination may be derived for direct printing of the mask 100 or a mold to prepare the mask 100 having the eye opening 102 currently formed therein as the mask 100 is formed. Alternatively, the data may be converted or translated into a cutting path or a machine path.

In various embodiments, the curvature of the first edge 104 and the second edge 106 of the ocular opening 102 is defined to have a degree of curvature corresponding to the inner liners 18, 20 of the lower and upper eyelids 14, 16.

In various embodiments, the method includes determining the location of medial canthus 26 and the location of lateral canthus 28, and positioning the third anchor point and the fourth anchor point relative to eyeball 12 between 0mm and 10mm from the lateral sides of medial canthus 26 and lateral canthus 28, respectively. In such embodiments, defining at least one ocular opening 102 may include defining a perimeter curve that intersects at a first edge 104 through the first anchor point, the third anchor point, and the fourth anchor point, and at a second edge 106 through the second anchor point, the third anchor point, and the fourth anchor point. In various embodiments, additional anchor points may be used.

In various embodiments, the method may include or further include determining the location of medial canthus 26 and the location of lateral canthus 28 and defining ocular opening 102 such that corners 110, 112 of ocular opening 102 are spaced about 0mm to about 10mm relative to eyeball 12 from the lateral sides of medial canthus 26 and lateral canthus 28, respectively. As used herein, unless otherwise indicated, "lateral to medial canthus 26" or "lateral to lateral canthus 28" refers to being positioned laterally to the corresponding canthus relative to the location of eyeball 12. That is, the eyeball 12 is considered to be located medially at the corresponding canthus.

In various embodiments, the method may include obtaining a digital geometric representation of a user's face. Fig. 5 shows one embodiment for obtaining such a digital representation. Any known method of obtaining a digital representation of an object such as a face or converting an image to a digital geometric representation may be used. In various embodiments, the method may include one or more of display, storage, and transmission of a digital representation or data associated therewith. Any known method, storage medium, and display system and apparatus may be used.

Referring to fig. 6, according to embodiments of the present disclosure, the mask 100 may include an eye opening 102 defined according to embodiments of the methods of the present disclosure. As shown in fig. 6, the mask 100 may also include a mouth opening 124 and/or a nose opening 114, as described in more detail below.

Referring to fig. 7A, a mask 100 according to various embodiments of the present disclosure may have an eye opening 102 having opposed first and second curved edges 104, 106, wherein a height H _EO extends between the edges 104, 106. The first edge 104 may be disposed about 0mm to about 10mm below the lower boundary 66 of the ocular region. The second edge 106 may be disposed about 0mm to about 10mm above the upper boundary 68 of the ocular region. The height H _EO of the ocular opening 102 may be defined by the maximum distance between the first edge 104 and the second edge 106. In various embodiments, the mask 100 can have an eye opening 102 height H _EO that is at least equal to the eye height H _E.

The mask 100 according to embodiments of the present disclosure may have a first edge 104 of the eye opening 102 that is disposed about 0mm to about 10mm below the lower boundary 66 of the eye region when the mask 100 is worn. According to various embodiments, the ocular opening 102 may include a second edge 106 that is disposed about 0mm to about 10mm above the upper boundary 68 of the ocular region 10 when the mask 100 is worn.

In various embodiments, mask 100 may include or further include ocular opening 102 having first and second corners (also referred to as lateral edges) 110, 112 spaced from medial and lateral canthus 26, 28, respectively, by about 0mm to about 10mm. First corner 110 and second corner 112 may be the same or different spacing from medial canthus 26 and lateral canthus 28, respectively.

In any of the embodiments herein, the mask 100 or the method of making the mask 100 may include defining the mask 100 to have a first eye opening and a second eye opening 102 corresponding to two eyes of a user.

In various embodiments, the mask 100 or a method of preparing the mask 100 may include defining registration features in the mask 100 to help align the mask 100 when worn. For example, in embodiments, the registration feature may be a portion of the mask 100 that covers one or more of the nose or portion thereof, the chin or portion thereof, and the jaw. The covering of such portions comprising the mask 100 may help a user align the mask 100 when applied such that the openings of the mask 100 are properly aligned with the target area.

According to an embodiment, the method may further comprise determining a relative spacing between the eyes of the user, and defining the mask to have a spacing within 0mm to 10mm of the spacing between the eyes of the user. The spacing between the eyes of the user may be defined as the spacing between the inner canthus 26 of each eye, and the spacing between the eye openings of the mask may be defined between the first corners of each eye opening. In an embodiment, the method may further include determining a relative spacing between one or more features for which an opening is to be defined. For example, where the mask 100 is formed to have an eye opening and a mouth opening, the spacing between features of the mouth and features of the eyes may be determined, and the mask may be defined to have a spacing of about 0mm to about 10mm, with the mask spacing defined between features or boundaries of the opening being disposed adjacent selected features of the eyes and mouth. Such determination of the relative spacing of facial features and associated openings may be made for any opening and target area. For example, the relative spacing between the base of the nostril or columella and the upper lip may be used to define the spacing between the upper boundary of the mouth opening and the lower boundary of the nasal opening. In some embodiments, the Pupillary Distance (PD) or interpupillary distance (IPD) may be used to determine the relative spacing between the eyes.

In any of the embodiments disclosed herein, the mask 100 can be a two-dimensional mask or a three-dimensional mask. According to embodiments, the two-dimensional mask may be a base mask, a nonwoven mask, a woven mask, a knitted mask, a paper mask, a cotton mask, any other type of woven, nonwoven, gel, hydrogel-type mask made from natural or synthetic fibers, composites, gels, hydrogels, films, apertured films, or any other such mask-making materials known in the art. In any of the embodiments disclosed herein, the three-dimensional mask can be a self-supporting mask. As used herein, the term "self-supporting" refers to the element of the applicator, or its entirety, retaining a substantial portion of a defined three-dimensional shape when resting on a horizontal surface in air, without the aid of an external support structure. In any embodiment, the mask may be a semi-three dimensional mask in which cuts, creases or seams are used in a planar base material to form a less planar or more three dimensional mask. In any of the embodiments disclosed herein, the mask can be a single dose applicator or a disposable applicator with a single dose of active agent, cosmetic agent, and/or therapeutic agent. As used herein, the term "single dose" means that the applicator contains enough active agent to provide the user with only a single administration of the active agent via the applicator. In any of the embodiments disclosed herein, the mask can be used for multiple uses. For example, the active agent, cosmetic agent, and/or therapeutic agent may be administered and reapplied sequentially for multiple uses. In any of the embodiments disclosed herein, the mask may be disposable. As used herein, the term "disposable" refers to an applicator that is intended to be discarded after use, and not a durable or semi-durable appliance intended for multiple users to reapply or not reapply active agents. In any embodiment, the mask may be a durable item suitable for washing by hand or in a dishwasher or washing machine.

In various embodiments, the ocular region lower boundary 66 may be defined at one or more of a minimum of the one or more lower lashes 22 of the at least one eye when the eye is open, a lower boundary of the eyeball 12 determined by the peak point 32 of the concave arc in the lower eyelid 14 of the at least one eye when the eye is closed, and a minimum of the one or more upper lashes 24 of the at least one eye when the eye is closed. For example, in an embodiment, the peak point 32 of the concave arc in the lower eyelid 14 may be manually determined by rotating a three-dimensional image of its face or eye region and digitally changing the angle of the light to estimate the position of the peak point 32 of the concave arc. In embodiments, for example, the peak 32 of the concave arc in the lower eyelid 14 may be determined by taking a cross-section perpendicular to the direction of curvature perpendicular from forehead to chin in a three-dimensional image of the face or eye region and observing the lowest point in the cross-section. A cross-section may be taken at one or more fiducial points in the ocular region to define points that are then connected to form a concave arc defining the ocular boundary. In other embodiments, an algorithm such as a machine learning algorithm, neural network, or deep learning algorithm may be used to teach the software tool to identify peak points 32 of the concave arc on the digital representation of the face or at least the eye region thereof.

For any of the disclosed fiducial points or anchor points, these points may be identified manually or by machine learning algorithms, image analysis, or other methods, such as face feature point detection such as Dlib (available from Github company). The reference point or anchor point may be determined in part by the application and/or by the user. Pixels in the 2D image or 3D information may be used to select anchor points by edge finding algorithms, feature extraction, using textures, colors, RBGs or gray values, shadows, or other features from the 2D image or 3D surface. In various embodiments, the ocular region lower boundary 66 is the floor of one or more lower lashes 22 of at least one eye when the eye is open. In some embodiments, the ocular region lower boundary 66 is the lower boundary of the eyeball 12 determined by the peak point 32 of the concave arc in the lower eyelid 14 of at least one eye when the eye is closed. In some embodiments, the lower ocular boundary is the ceiling of the minima of one or more lower lashes 22 of at least one eye when the eye is open.

In various embodiments, the ocular region lower boundary 66 is the floor of one or more lower lashes 22 of at least one eye when the eye is open. For example, the lower ocular region boundary 66 may be the lowest limit of the longest lower lashes of the lower lashes 22 of at least one eye. Alternatively, the lower eye region boundary 66 may be defined at a minimum average value for each of the lower lashes 22.

Fig. 7A and 7B illustrate embodiments of the mask 100 and method of the present disclosure, wherein the eye region lower boundary 66 is selected to be the peak point 32 of the concave arc in the lower eyelid 14 of at least one eye when the eye is closed. Fig. 8 illustrates an embodiment of the mask 100 and method of the present disclosure, wherein the eye region lower boundary 66 is selected to be the minimum of one or more lower lashes 22 when the eyes are open.

In various embodiments, the ocular opening 102 of the mask 100 has or is defined to have a first edge 104 that is arranged to contact or have a defined spacing from the ocular region lower boundary 66 when the mask 100 is worn. The first edge 104 of the eye opening 102 may be positioned about 0mm to about 10mm below the lower boundary 66 of the eye region. For example, the first edge 104 of the ocular opening 102 may be about 0mm to about 10mm, about 1mm to about 4mm, about 0mm to about 5mm, about 2mm to about 6mm, about 1mm to about 8mm, and about 5mm to about 10mm. In various embodiments, the first edge of the ocular opening 102 may be about 0mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, or 10mm below the ocular region lower boundary 66. In various embodiments, the lowest point of the first edge 104 of the eye opening 102 furthest from the eye region lower boundary 66 may be used as a reference point for measuring the distance between the eye region lower boundary 66 and the first edge 104 of the eye opening 102.

Positioning the first edge 104 of the ocular opening 102 about 0mm to 10mm from the ocular region lower boundary 66 may advantageously provide an ocular opening 102 that closely conforms to the eye, allowing maximum coverage of the under-eye region without discomfort by interfering with the lower eyelashes 22 or too closely overlapping the edges of the lower eyelid 14.

In embodiments, the ocular region upper boundary 68 may be determined by locating the upper boundary of the eyeball 12, which is determined by the peak 34 of the concave arc in the upper eyelid of at least one eye when the eye is closed. The mask 100 may have an eye opening 102 that is positioned such that the second edge 106 is at or above the eye region upper boundary 68 when worn. It has been found that the eye opening 102 positioned at or above the peak 34 of the concave arc in the upper eyelid provides improved comfort to the user because the mask 100 does not rest on the upper eyelid 16 in a manner that impedes movement of the eyelid or eyeball 12.

In various embodiments, the second edge 106 may also or alternatively be spaced apart to be at or above the ceiling of the upper eyelashes 24 when the eye is open. In various embodiments, the ceiling of the upper eyelashes 24 may be the ceiling of the longest upper eyelashes 24 of the upper eyelashes 24 of at least one eye. Alternatively, the ceiling of the upper lashes 24 may be an average of the ceiling of each upper lashes 24.

The second edge 106 of the eye opening 102 may be positioned about 0mm to about 10mm above the upper boundary of the eye region 10. For example, the second edge of the ocular opening 102 may be about 0mm to about 10mm, about 1mm to about 4mm, about 0mm to about 5mm, about 2mm to about 6mm, about 1mm to about 8mm, and about 5mm to about 10mm above the upper boundary of the ocular region 10. In various embodiments, the first edge of the ocular opening 102 may be about 0mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, or 10mm above the upper boundary of the ocular region 10. In various embodiments, the highest point of the second edge of the eye opening 102 furthest from the upper boundary of the eye region 10 may be used as a reference point for measuring the distance between the eye region 10 boundary and the second edge of the eye opening 102.

Fig. 7A and 7B illustrate embodiments in which the second edge 106 is disposed within 0-10mm of the peak 34 of the concave arc in the upper eyelid 16. Fig. 8A and 8B illustrate an embodiment in which the second edge 106 is spaced a distance above the peak 34 of the concave arc in the upper eyelid 16 and at the ceiling of the upper eyelash 24. Fig. 9A and 9B and fig. 10A and 10B illustrate embodiments in which the second edge 106 is spaced from the upper ocular region boundary 68 by a distance of about 2mm to about 4 mm. Fig. 11A and 11B illustrate an embodiment in which the second edge 106 is disposed near the edge of the eye socket.

According to embodiments of the present disclosure, the method may include obtaining one or more digital geometric representations of at least one eye region 10 of a user's face. The digital geometric representation may include a variation in which the eyes of the user are open and the eyes of the user are closed. The digital geometric representation may include an image or scan representing the front profile and/or side profile of the user. In various embodiments, the digital geometric representation may be a digital geometric representation of the entire user's face or the entire eye region 10, including both eyes or any portion of the user's face including at least one eye region 10.

The digital geometric representation may be obtained, for example, by any one or more of a 3D scanner, a 2D scanner, a camera, a smart phone camera, a digital application of a tablet and phone, and other known devices for obtaining digital geometric data. ARTEC SPIDER from Artec Group Palo Alto, CA is an example of a suitable 3D scanner. Exemplary mobile applications for cellular phones or tablet computers are 123D Catch from Autodesk, or Capture:3D Scan Anything"by developer,Standard Cyborg, or Bellus3D FaceApp from Bellus3D inc, or TrueDepth camera system from Apple.

The digital geometric representation of the face or portion thereof may be used as a whole or separate from only a portion of the overall representation used. Further, portions of geometries derived by scanning or other imaging techniques may be removed or edited from the digital geometric representation. The digital geometry representation data may be used without change or the geometry of the representation may be changed. For example, digital processing may be used to change digital data. For example, the digital data may be changed to be provided as a grid, allowing various features to be measured based on the digital data. For example, a two-dimensional dataset from an image or scan may be changed to provide a three-dimensional representation of the two-dimensional data.

In any of the embodiments of the present disclosure, any one or more of the various digital processing devices, digital geometric representations, graphical programs, and graphical displays may be stored in a tangible computer readable memory or medium and/or a shared or cloud-based medium and executed by one or more processors to perform the functions described herein. For example, in an embodiment, the digital geometric representation may be obtained by a user using a smart phone camera and/or a mobile application and then uploaded to the manufacturer's shared memory or medium for use in manufacturing the mask 100. In other embodiments, the digital geometric representation may be obtained with a scanner or other imaging device located at the point of sale of the mask 100. Data from the digital geometric representation may be stored on a local or shared medium.

In various embodiments, a digital geometric representation is used to define an ocular region lower boundary 66 and an ocular region upper boundary 68. Various graphics programs may be used to obtain measurements and manipulations of data for digital geometric representations. For example, blender Foundation Blender may be used to view, manipulate, and/or modify digital geometric representation data. In various embodiments, the digital geometric representation may be used to define anchor points corresponding to the lower ocular region boundary 66 and the upper ocular region boundary 68. A method according to an embodiment of the present disclosure includes defining at least two anchor points for the ocular opening 102. In some embodiments, the method may include defining more than two anchor points. For example, in embodiments, the method may include defining four anchor points corresponding to upper eye region boundary 68, lower eye region boundary 66, medial canthus 26, and lateral canthus 28. Any suitable number of anchor points may be defined.

In various embodiments, the anchor points are used to define the peripheral edge of the ocular opening 102. As described herein, the anchor points may be disposed at or offset from the respective target features of the eye. For example, the anchor point may be located about 0mm to about 10mm below the anchor point corresponding to the lower boundary 66 of the ocular region. For example, the anchor point may be located about 0mm to about 10mm above the anchor point corresponding to the upper boundary 68 of the ocular region. In any embodiment, the anchor points may be offset from the corresponding target features of the ocular region by about 0mm to about 10mm.

Once at least two anchor points are defined, the method may include fitting one or more curves to the anchor points. For example, a bezier curve may be used to fit a curve corresponding to the peripheral edge of the ocular opening 102 to at least two anchor points. In any of the embodiments disclosed herein, one or more of the following may be used to connect or contact the anchor points to define the opening: bezier curves, straight line segments, parabolic lines, concave curves, regular or irregular curves, and polygons. In various embodiments, the connection defining the edge of the opening may be curved or may have any of the shapes described above. In various embodiments, the connection may simulate, follow, or be parallel to all or part of the curvature and path of the underlying physiological features of the feature in the target region. For example, the connection may simulate, follow, or be parallel to the curvature of the eyebrows and eye folds or the shape of the eye. Such mimicking, following, or paralleling may help to functionally conform the opening to the face of a particular user, and may provide a more aesthetically pleasing wearing experience. In other embodiments, the curve may be defined on digital geometric data from the curvature of the liner of the upper and lower eyelids and digitally offset to intersect the anchor point. Other methods of fitting a curve to a point known in the art may be used. In embodiments using a bezier curve, the curve may be digitally superimposed over the digital representation in the ocular region 10, and the stem of the anchor point may be continuously adjusted until the curve follows a point that tracks the lowest curvature of the underlying eyeball 12 and intersects the anchor point.

Once the curve of the ocular opening 102 is digitally defined, the data may be exported in any suitable file format for use in forming the mask 100. For example, a series of segments may be used to convert the curve into a grid that allows export to a cutting tool or other digital tool for printing the mask 100 or defining a mold for preparing the mask 100. For example, the data for the curve may be converted to a mesh and exported as a DXF file. When converting the curve defining the ocular opening 102 into a mesh, about 30 to about 100 segments may be used. For example, the grid may be generated using from about 30 to about 100 segments, from about 50 to about 100 segments, from about 30 to about 60 segments, from about 40 to about 80 segments, or from about 70 to about 90 segments. Other suitable numbers of segments include about 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, and 100 segments. In some embodiments, a digital mesh defining a curve of the ocular opening 102 is exported to a digital cutting tool and used as a cutting path to cut the ocular opening 102 in the mask 100 material.

In other embodiments, the grid of curves may be used to generate a digital geometric representation of the mask 100 that will be formed with the ocular openings 102, rather than cutting the ocular openings 102 after the mask 100 is formed, which may be accomplished by any method, including but not limited to thermoforming, hydroforming, and vacuum forming. In embodiments, the ocular opening may be cut by any method, including, but not limited to: laser cutting, water jet cutting, manual cutting, die cutting, hot air cutting, as described in U.S. patent application publication No. 2017/0354805, which is incorporated herein by reference. For example, digital printing apparatus employing methods of forming mask 100 materials using various techniques, such as SLS, SLA, FDM, CLIP and other additive manufacturing techniques known in the art, may be used. The defined mesh of curves of the eye opening 102 may be incorporated into the mesh of the mask 100, digitally eliminating the mask 100 material in the eye opening 102, thereby defining a mask 100 having preformed eye openings 102. In one embodiment, the curved mesh of the eye opening 102 may be digitally placed over the eyes of the facial mesh defining the area of the mask 100 and squeezed out in the negative Z-direction to intersect the facial mesh and pass through the facial mesh. The intersection region of the face mesh into the curve is selectively removed to define an opening. Digital removal of a portion of the grid may be accomplished, for example, using boolean differencing. The data associated with the mask 100 having the digital removal area to define the customized eye opening 102 may then be exported to a suitable printing or manufacturing apparatus to form the mask 100 itself.

According to various embodiments, the method of making the mask 100 may include or further include defining one or more of the nasal opening 114 and the mouth opening 124 in the mask 100.

According to various embodiments, the mask 100 may include or further include nasal openings 114.

According to any of the embodiments of the present disclosure, the mask 100 may be a two-dimensional mask 100, or may be a three-dimensional mask 100. The mask 100 may be made using any suitable technique in which the opening features defined by the methods disclosed herein may be incorporated. For example, methods according to embodiments of the present disclosure may be used to define a cutting path for cutting openings into a preformed mask 100 material or a flat mask material such as a base mask. According to embodiments, laser cutting may be used to cut a defined cutting path. Additionally or alternatively, in embodiments, custom defined molds may be used to define gel masks having one or more openings according to embodiments of the present disclosure. For example, methods according to embodiments of the present disclosure may be used to define open areas in a digital geometric representation of a three-dimensional mask 100 that is to be formed by digital printing or other molding techniques. For example, the mask 100 may be digitally formed using techniques such as those described in any one or more of U.S. patent application publication nos. 2017/008566, 2017/0354805, and 2017/0354806, the respective disclosures of which are incorporated herein by reference. The method of defining the one or more openings may be manual or partially or fully automatic, and various algorithms may be used. In addition, the viewing angle of the image may be considered and/or measured to ensure data quality. The perspective correction may use a comparison of multiple images, telephony sensor data, by guiding the user during acquisition of the images and any digital data, or otherwise.

The mask 100 having openings prepared according to the methods of embodiments of the present disclosure may comprise any suitable active agent, cosmetic agent, or therapeutic agent to be applied to the face of a user. For example, the active agent, therapeutic agent, and/or cosmetic agent may comprise an active ingredient, carrier, base structure, emulsion, hydrogel, adhesive, processing aid (such as a thickener, rheology modifier, etc.). The active agent may also include a release layer to facilitate transfer of the active agent from the applicator to the target surface. The active agent may include an adhesive material, an active chemical agent, an absorbent material such as an absorbent gel material or absorbent foam material placed according to a diagnostic scan or relative to identifiable features. For example, it may be desirable to place absorbent foam along the cheekbones, eyebrows, or nose of the scanned user's mask 100, where placement may be determined based on the geometry of the representation and not on the diagnostic scan of the user. The active agent may be in one or more physical forms including, but not limited to: foams, liquids, powders, films, fibers, creams, gels, hydrogels, encapsulated actives, solids, combinations of these forms, and others. Some examples of active agents include, but are not limited to: moisturizers, anti-aging agents, anti-wrinkle agents, skin color control agents, anti-irritants, sensates (e.g., menthol), heating or cooling chemicals, tightening agents, dehairing agents, hair regenerating agents, fungicides, antibacterial agents, antiviral agents, surfactants, cleaners, copper ion eluents (such as those available from Cupron, richmond, va.), antioxidants, vitamins, sunscreens, regenerants, wound healing agents, sebum management agents, astringents, exfoliants, anti-inflammatory agents, lotion-free agents, overnight treatments, dry skin treatments, itchy skin treatments, cracked skin treatments, peptides, acne treatments, scar treatments, muscle soreness treatments, pharmaceuticals, including pharmacologically active substances that treat disease states or other acute or chronic problems such as eczema, rash, acne, cancer, herpes labialis, psoriasis, rosacea, vitiligo, warts, herpes, fungal infections, actinic keratosis, ulcers, shingles, paint-induced rash, and insect bites. In addition, drugs including pharmacologically active substances may exceed the local effects and are designed for transdermal delivery of the active substance into the blood stream or other internal tissues. Examples of prescription and over-the-counter therapies include: nicotine, botulinum toxin and hormone supplements.

Exemplary active agents for making cosmetic changes to a target structure include: moisturizers, acne treatments, anti-aging agents, anti-wrinkle agents, matte compounds, under-eye moisturizers, anti-oil agents, pre-makeup creams, lipsticks, lip colors, lip liners, lip lotions, pre-makeup lipsticks, lip lotions, concealers, foundations, powders, rouges, blushes, silhouettes/creams, highlighters, paleo-powders, mascaras, eyeliners, and make-up, fragrances, perfumes, or fragrance compositions (e.g., essential oils).

In one embodiment, the contained one or more fragrances, perfumes, or fragrance compositions may be applied into the mask 100 for subsequent deposition onto the face. However, some or all of the one or more fragrances, perfumes, or fragrance compositions contained may be used as an experiential. In use, the sensates provide odors in the environment of the mask 100. For example, when applying a cosmetic to the face of a consumer/wearer, the scent provided by the fragrance that exhibits an outdoor garden scent may be desirable. The sensates are not necessarily located on the target structure contacting surface of the mask 100. The agent may be located in an area that is not in contact with the target structure, such as on a non-contact portion of the application side of the applicator or at any location on any application side that is not in contact with the target structure. The experience agent may be selected to accompany the selected appearance feature.

Examples

Example 1

The ocular opening 102 cutting path is digitally formed using methods according to the present disclosure. Fig. 7A and 7B illustrate a mask 100 formed from the developed custom eye opening 102.

Digital data corresponding to the three-dimensional mesh of the face is loaded into the Blender graphics program. The facial mesh is aligned flat with the nose pointing in the positive Z direction, the chin and forehead at approximately the same Z height, and the left and right cheeks at approximately the same Z height. The face mesh is oriented in a top-down elevation view. The face mesh is viewed with and without captured texture/color information to provide supplemental information about where the fiducial is located.

Four anchor points are selected on the face digital geometric representation presented as a grid. When the eye is closed, an eye region lower boundary 66 is defined at the very least of the upper eyelashes 24. First anchor point 104 is disposed about 3.5mm below lower ocular region boundary 66. An upper ocular region boundary 68 is defined at peak 34 of the concave arc of upper eyelid 16. The second anchor point 106 is disposed about 3.5mm above the upper boundary 68 of the ocular region. The locations of medial canthus 26 and lateral canthus 28 are determined on the grid, and third anchor point 110 and fourth anchor point 112 are positioned about 3.5mm from the lateral (relative to eyeball 12) sides of medial canthus 26 and lateral canthus 28, respectively. The grid is manipulated at various angles in the software to help define anchor points.

The bezier curve is superimposed over a digital geometric representation floating 2cm above the digital geometric representation of the eye with four anchor points. The stem of each anchor point is continuously adjusted until the bezier curve follows the lowest point of curvature of the following eyeball 12. Once implemented, the bezier curve defines the ocular opening 102.

The bezier curves are converted to grids and exported as DXF files for use in XY laser cutters. The grid of the generated bezier curve has about 50 segments. The eye opening 102 is then cut into the shaped mask using a laser cutter, thereby forming the eye opening 102 shown in fig. 7A and 7B.

Example 2

A method according to the present disclosure generates a facial mesh having an eye opening 102 defined therein for directly printing a mask having an eye opening formed at the time of printing.

The eye openings 102 are then digitally formed in the face mesh using bezier curves, and the mask is then printed directly, with the defined eye openings removed at the time of printing. The bezier curve is converted into a mesh having about 50 segments and is squeezed out in the negative Z direction to the extent that it intersects and passes through the face mesh surface. Specifically, the bezier curve is initially 20mm above the eyes of the face mesh and is extruded-50 mm to intersect the face mesh. A facial mesh is then selected and the boolean differences from the extruded mesh eye opening cutting path are used to remove the eye regions within the cutting path to leave defined eye openings in the facial mesh. The resulting facial mesh from which the eye openings have been removed can then be derived for direct printing.

Example 3

The nasal opening 114 cutting path is digitally formed using methods according to the present disclosure. Fig. 12 shows a mask 100 formed from the developed custom nasal opening 114.

Four anchor points are selected on the face digital geometric representation presented as a grid. Left and right anchor points 120 and 122 are provided as midpoints of the outer nasal wall on either side 46 and 48. The upper anchor point 118 is positioned at the center of the nose above the columella and 3mm above the highest point of the nostril 49. The lower anchor point 116 is set to the center of the nose below the columella and 3mm below the base of the columella 44. The grid is manipulated at various angles in the software to help define anchor points.

The bezier curve is superimposed over a digital geometric representation floating 2cm above a digital geometric representation of the nose with four anchor points. The stem of each anchor point is continuously adjusted until the bezier curve follows the centerline of the nostril sidewalls 46, 48. Once achieved, the bezier curve defines the nasal opening 114.

The bezier curves are converted to grids and exported as DXF files for use in XY laser cutters. The grid of the generated bezier curve has about 50 segments. The nasal openings 114 are then cut into the mask material using a laser cutter, thereby forming the nasal openings 114 shown in fig. 12.

Example 4

A method according to the present disclosure generates a facial mesh having nasal openings 114 defined therein for directly printing a mask having nasal openings formed upon printing.

Nasal openings 114 are then digitally formed in the facial mesh using bezier curves, and the mask is then printed directly, with the defined nasal openings removed at the time of printing. The bezier curve is converted into a mesh having about 50 segments and is squeezed out in the negative Z direction to the extent that it intersects and passes through the face mesh surface. Specifically, the Bezier curve is initially 20mm above the nose of the face mesh and is extruded-50 mm to intersect the face mesh. The facial mesh is then selected and the nasal area within the cutting path is removed using the boolean difference from the extruded mesh nasal opening cutting path to leave a defined nasal opening in the facial mesh. The resulting facial mesh from which the nasal opening has been removed can then be exported for direct printing.

Example 5

The mouth opening 124 cutting path is digitally formed using methods according to the present disclosure. Fig. 13 shows a mask 100 formed from the developed custom mouth opening 124.

Digital data corresponding to the three-dimensional mesh of the face is loaded into the Blender graphics program. The facial grid is aligned flat with the mouth pointing in the positive Z direction, the chin and forehead at approximately the same Z-height, and the left and right cheeks at approximately the same Z-height. The face mesh is oriented in a top-down elevation view. The face mesh is viewed with and without captured texture/color information to provide supplemental information about where the fiducial is located.

Four anchor points are selected on the face digital geometric representation presented as a grid. Left and right anchor points 130 and 132 are disposed 3mm from corners 62 and 64 of the mouth. The upper anchor point 128 is set 3mm above the upper lip 58 at the center of the mouth. The lower anchor point 126 is set 3mm below the lower lip 60 at the center of the mouth. The grid is manipulated at various angles in the software to help define anchor points.

The bezier curve is superimposed over a digital geometric representation floating 2cm above a digital geometric representation of the mouth with four anchor points. The shank of each anchor point is continuously adjusted until the bezier curve generally follows the lip redness at an offset of at least 3 mm. Once implemented, the bezier curve defines the mouth opening 124.

The bezier curves are converted to grids and exported as DXF files for use in XY laser cutters. The grid of the generated bezier curve has about 50 segments. The mouth opening 124 is then cut into the mask material using a laser cutter, thereby forming the mouth opening 124 shown in fig. 13.

Example 6

A method according to the present disclosure generates a facial grid having mouth openings 124 defined therein for direct printing of a mask having mouth openings formed upon printing.

Mouth openings 124 are then digitally formed in the face mesh using bezier curves, and the mask is then printed directly, with the defined mouth openings removed at the time of printing. The bezier curve is converted into a mesh having about 50 segments and is squeezed out in the negative Z direction to the extent that it intersects and passes through the face mesh surface. Specifically, the Bezier curve is initially 20mm above the mouth of the face mesh and is extruded-50 mm to intersect the face mesh. A face mesh is then selected and a boolean difference from the extruded mesh mouth opening cutting path is used to remove mouth regions within the cutting path to leave defined mouth openings in the face mesh. The resulting face mesh from which the mouth opening has been removed can then be derived for direct printing.
