Description

Method of making an applicator with a precision eye opening

Technical Field

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

Background

Agents for influencing the structure of interest are well known. The temperature effect may be induced by applying hot or cold agents to the target. The appearance of the target may be affected by cosmetic and decorative agents. Local applicators can be used to apply current, voltage, and electric and magnetic fields to a target. For biological targets, surface characteristics can be influenced by topical application of moisturizers, drugs and other treatment actives.

The effectiveness of the active agent can be influenced by the nature of the applicator, which can be used to facilitate interaction of the active agent with the target structure. Typical applicators are less precise in their conformability to the target structure and often compromise the actual performance of the active agent for all uses of only one size or a few sizes. In particular, conventional universal applicators for facial products, for example, typically have widely large eye and lip openings to accommodate differences in user characteristics. Thus, such applicators are ineffective for administering active agents in the region of the eyes or lips of many individuals. In addition, alignment of the eye and lip openings can be particularly difficult and cause discomfort to the user given the generally poor fit and registration of conventional applicators on the face.

Disclosure of Invention

According to embodiments, an applicator having a custom sized opening and method of making the same may include an applicator having an agent for affecting a target structure, such as a cosmetic mask.

According to an embodiment, a method of preparing a mask for a face of a human user may include determining a lower boundary of an eye region. For example, the eye region lower boundary may be determined by locating the position of one or more of the nadirs of one or more lower eyelashes of at least one eye when the eye is open, the lower boundary of the eyeball determined by the peak of the concave arc in the lower eyelid of at least one eye when the eye is closed, and the nadirs of one or more upper eyelashes of at least one eye when the eye is closed. The method may also include determining an upper boundary of the ocular region. For example, the upper eye region boundary may be determined by locating the upper boundary of the eyeball, which is determined by the peak 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 fitted to the face, the first edge is disposed 0mm to about 10mm below a lower boundary of the eye region and the second edge is disposed 0mm to about 10mm above an upper boundary of the eye region. The method can also 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. The applicator may also be used interchangeably herein with "mask".

Referring to fig. 1A-1C, the 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. Lower eyelashes 22 and upper eyelashes 24 extend from the

eyelid liners

18, 20. Ocular region 10 also includes medial and lateral canthus 26 and 28. The eyebrows 30 are positioned over the upper eyelid 16.

The boundary of the eyeball 12 may be visually determined outside of the upper eyelid 14 and the lower eyelid 16. Referring to fig. 1A and 1C, the lower boundary of the eyeball 12 is disposed at the peak 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 depressions in the upper eyelid 14 and the lower eyelid 16 formed by the boundary 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 nasal region 36 may include a central nose tip 38, first and

second nostrils

40, 42, and a columella separating the first and

second nostrils

40, 42. The first and

second nostrils

40, 42 are each defined by

outer nostril walls

46, 48 and are internally defined by the columella. The columella terminates at a base 44.

Referring to fig. 3, the mouth region 50 includes an upper lip 52 and a lower lip 54 which are bounded on their outer peripheries by a lipped lip 56. The lipstick rim 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 a universal type of eye opening 202 and spacing. Such masks 200 also typically have universal-type 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 the face of many users. In the case of the ocular region, such conventional non-conforming masks 200 may cause discomfort by resting on or covering the eyes and/or causing ineffective treatment, as the openings cover the area under the eyes to be treated, rather than the mask surface with the active, cosmetic and/or therapeutic agent. Similarly, in the mouth region, a non-conforming mask 200 may overlap the lip region or be spaced too far from the lip or nose portion thereof. In this area, 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 can 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 embodiments, methods 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 an inner eyelid liner 18 proximate a lower eyelid 14 of a user to achieve improved coverage of an area under the eye by the portion of the mask 100 having an active, cosmetic, and/or therapeutic agent disposed thereon. According to other or additional embodiments, methods according to the present disclosure may provide a mask 100 having a pair of ocular openings 102 spaced apart such that each opening is located at a desired, proximate, but non-overlapping location from the medial canthus 26. According to other or additional embodiments, methods according to the present disclosure may provide a mask 100 having a nasal opening 114 that partially overlaps the outer

nasal wall

46, 48, but does not interfere with the

nares

40, 42 or cause discomfort while breathing. According to other or additional embodiments, a method according to the present disclosure can provide a mask 100 having a mouth opening 124 that is spaced proximate to the lipped edges 56 of both the upper lip 52 and the lower lip 54. According to embodiments of the present disclosure, the mask and method of making the same may include any combination of custom defined openings and/or standard sized (universally suitable) openings. For example, a mask can include a custom-defined mouth opening and a standard-sized eye opening according to embodiments of the present disclosure. For example, a mask can include custom-defined eye openings and standard-sized nose and/or mouth openings according to embodiments of the present disclosure. For example, a mask can include a custom-defined nasal opening according to embodiments of the present disclosure, without an opening for the eyes or mouth. For example, a mask may include custom defined eye, mouth, and nose openings according to embodiments of the present disclosure. Any other such combination of defining openings 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 areas of the face. The desired area may include, for example, one or more of the sub-ocular region, the corners of the nose 45 that are located outside the outer

nasal wall

46, 48, and the skin near the lips. Improved fit may include the mask 100 covering such desired areas without giving up coverage in other areas such as over the eyes and/or without interfering with facial features such as the eyeballs 12,

nostrils

40, 42, and/or lips 52, 54 that should be avoided. The mask 100 according to embodiments of the present disclosure may also have improved fit, not only contacting the desired area, but also maintaining closer contact without gaps or bubbles in the mask 100 that would interrupt contact with the desired area.

Referring to fig. 4, a method of making 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 having a first edge intersecting the first anchor point and a second edge intersecting the second anchor point. As used herein, an anchor point refers to a digital reference point that is a fixed point in space and is selected on the digital representation of the target area.

According to an embodiment of the present disclosure, a method of preparing a mask 100 for a face includes determining an eye region lower boundary 66; determining an upper eye region boundary 68 by locating the upper boundary of the eye 12; and defines at least one eye opening 102 such that when the mask 100 is fitted to the face, the first edge 104 is disposed 0mm to about 10mm below the eye region lower boundary 66 and the second edge 106 is disposed 0mm to about 10mm above the eye region upper boundary 68. The method can also include forming a mask 100 having at least one eye opening 102. The eye openings can 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 ocular region upper boundary 68 can be one or more of: the peak 34 of the concave arc in the upper eyelid 16 of at least one eye when the eye is closed; a peak point of a crease line 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 peak of the upper eyelashes may be selected in embodiments to be the average peak in a group or all of the upper eyelashes, or may be the peak of the longest upper eyelash when the eyes are open.

In any of the embodiments herein, the eye region lower boundary 66 may be determined by locating the position of one or more of the nadir of the one or more lower eyelashes 22 of the at least one eye when the eye is open, the lower boundary of the eyeball 12 determined by the peak 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 nadir of the one or more upper eyelashes 24 of the at least one eye when the eye is closed.

In any of the embodiments herein, the forming of the mask 100 can include exporting data related to the defined at least one eye opening 102 to a cutting tool to define a cutting path for cutting the eye opening 102 into the mask 100 substrate. Alternatively, the forming of the mask 100 can include combining digital data relating to the at least one defined 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 can be exported 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 transformed into a cutting path or a machine path.

In various embodiments, the curvature of the first and

second edges

104, 106 of the ocular opening 102 is defined as having a degree of curvature corresponding to the

inner liners

18, 20 of the lower and

upper eyelids

14, 16.

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

In various embodiments, the method can 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 from the lateral sides of medial canthus 26 and lateral canthus 28, respectively, by about 0mm to about 10mm relative to eyeball 12. As used herein, unless otherwise indicated, "lateral to the medial canthus 26" or "lateral to the lateral canthus 28" refers to the lateral location of the respective canthus relative to the location of the eyeball 12. That is, the eyeball 12 is considered to be located medial to the respective canthus.

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

Referring to fig. 6, a mask 100, according to an embodiment of the present disclosure, can include an ocular opening 102 defined according to an embodiment of a method of the present disclosure. As shown in fig. 6, the mask 100 can also include a mouth opening 124 and/or a nose opening 114, as described in detail below.

Referring to fig. 7A, a mask 100 according to various embodiments of the present disclosure can have an eye opening 102 with opposing first 104 and second 106 curved edges, wherein a height H_EOExtending between the

edges

104, 106. The first edge 104 may be disposed about 0mm to about 10mm below the lower eye region boundary 66. The second edge 106 can be disposed about 0mm to about 10mm above the upper eye region boundary 68. Height H of eye opening 102_EOMay 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 height H at least equal to_EHeight H of eye opening 102_EO。

A mask 100 according to embodiments of the present disclosure can have a first edge 104 of the eye opening 102 disposed about 0mm to about 10mm below the eye region lower boundary 66 when the mask 100 is worn. According to various embodiments, the eye opening 102 can include a second edge 106 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, the mask 100 can include or further include an ocular opening 102 having first and second corners (also referred to as lateral edges) 110, 112 spaced about 0mm to about 10mm apart from the medial and

lateral canthus

26, 28, respectively, laterally of the medial and lateral canthus 28. First corner 110 and second corner 112 may be at the same or different spacing from medial and lateral canthus 26 and 28, respectively.

In any of the embodiments herein, the mask 100 or the method of making the mask 100 can include defining the mask 100 as having a first eye opening and a second eye opening 102 corresponding to both eyes of a user.

In various embodiments, the mask 100 or method of making the mask 100 can include defining registration features in the mask 100 to help align the mask 100 when worn. For example, in an embodiment, the registration feature can be a portion of the mask 100 that covers one or more of the nose or a portion thereof, the chin or a portion thereof, and the jaw. Covering including such portions of the mask 100 can help a user align the mask 100 when applied so that the opening of the mask 100 is 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 can be defined as the spacing between the medial canthus 26 of each eye, and the spacing between the ocular openings of the mask can be defined between the first corners of each ocular opening. In embodiments, the method may further include determining a relative spacing between one or more features for which the 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 can be determined, and the mask can be defined to have a spacing of about 0mm to about 10mm of the spacing, where the mask spacing defined between features or boundaries of the openings is disposed adjacent to selected features of the eyes and mouth. This determination of the relative spacing of the facial features and associated openings may be made for any opening and target region. For example, the relative spacing between the base and the upper lip of the nostril or columella 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, 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 can 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 material 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 elements of the applicator, or the entirety thereof, maintaining a substantial portion of the defined three-dimensional shape when resting on a horizontal surface in the air, without the aid of an external support structure. In any embodiment, the mask can be a semi-three dimensional mask, wherein cuts, creases, or seams are used in a flat base material to form a less flat or more three dimensional mask. In any of the embodiments disclosed herein, the mask can be a single dose applicator or a disposable applicator having a single dose of an active agent, cosmetic agent, and/or therapeutic agent. As used herein, the term "single dose" means that the applicator contains sufficient 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 re-administered sequentially for multiple uses. In any of the embodiments disclosed herein, the mask can be disposable. As used herein, the term "disposable" refers to applicators that are intended to be discarded after use, rather than durable or semi-durable devices intended for multiple users to reapply or no longer administer an active agent. In any embodiment, the mask can be a durable article suitable for washing by hand or in a dishwasher or washing machine.

In various embodiments, the lower eye region boundary 66 may be defined at one or more of the lowest limits of the one or more lower eyelashes 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, and the lowest limit of the one or more upper eyelashes 24 of the at least one eye when the eye is closed. For example, in an embodiment, the peak 32 of the concave arc in the lower eyelid 14 may be determined manually by rotating a three-dimensional image of its facial or eye region and digitally altering the angle of the light to estimate the location of the peak 32 of the concave arc. In an embodiment, 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, which are then connected to form a concave arc defining the ocular boundary. In other embodiments, software tools may be taught using algorithms such as machine learning algorithms, neural networks, or deep learning algorithms to identify the peaks 32 of concave arcs on the digital representation of the face, or at least the eye regions thereof.

For any of the disclosed fiducial or anchor points, these points may be identified manually or by machine learning algorithms, image analysis, or other methods, such as human face feature point detection such as Dlib (available from Github corporation). The reference points or anchor points 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 discovery algorithms, feature extraction, using textures, colors, RBGs or grayscale values, shadows, or other features from the 2D image or 3D surface. In various embodiments, the eye region lower boundary 66 is the lowest of the lowest limits of the one or more lower eyelashes 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 as determined by the peak 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 eye boundary is the highest of the lowest limits of the one or more lower eyelashes 22 of at least one eye when the eye is open.

In various embodiments, the eye region lower boundary 66 is the minimum limit of one or more lower eyelashes 22 of at least one eye when the eye is open. For example, the eye region lower boundary 66 may be the lowest limit of the longest lower eyelash of the lower eyelashes 22 of at least one eye. Alternatively, the eye region lower boundary 66 may be defined at an average of the minimums of each of the lower eyelashes 22.

Fig. 7A and 7B illustrate an embodiment of the mask 100 and method of the present disclosure in which the eye region lower boundary 66 is selected as the peak 32 of a 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 in which the eye region lower boundary 66 is selected to be the minimum of one or more lower eyelashes 22 when the eyes are open.

In various embodiments, the eye opening 102 of the mask 100 has or is defined as having a first edge 104 that is arranged to contact or be spaced from the lower eye region 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 eye region lower boundary 66. For example, the first edge 104 of the eye opening 102 can 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 10 mm. In various embodiments, the first edge of the eye opening 102 can 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 eye region lower boundary 66. In various embodiments, the nadir of first edge 104 of eye opening 102 that is farthest from eye region lower boundary 66 may be used as a reference point for measuring the distance between eye region lower boundary 66 and first edge 104 of eye opening 102.

The positioning of the first edge 104 of the eye opening 102 about 0mm to 10mm from the lower eye area boundary 66 may advantageously provide the eye opening 102 with a close fit to the eye, allowing maximum coverage of the under eye area without discomfort by obstructing the lower eyelashes 22 or overlapping too closely with the edge of the lower eyelid 14.

In an embodiment, the ocular region upper boundary 68 may be determined by locating the upper boundary of the eyeball 12 as 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 can have an eye opening 102 that is positioned such that the second edge 106 is located 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 interferes with the movement of the eyelid or eyeball 12.

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

The second edge 106 of the ocular opening 102 can be positioned about 0mm to about 10mm above the upper boundary of the ocular region 10. For example, the second edge of the ocular opening 102 can 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 can 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 that is furthest from the upper boundary of the eye region 10 may be used as a reference point for measuring the distance between the boundary of the eye region 10 and the second edge of the eye opening 102.

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

According to an embodiment 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 variations in which the user's eyes are open and the user's eyes are closed. The digital geometric representation may include an image or scan representing the user's front contour and/or side contour. 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 smartphone camera, a tablet computer, and a digital application of a telephone, and other known devices for obtaining digital geometric data. Artec Spider available from Artec Group Palo Alto, CA is an example of a suitable 3D scanner. Exemplary mobile applications for a cell phone or tablet are 123D Catch, or Capture 3D Scan analysis "by devipper, Standard Cyborg, from Autodesk, or Bellus3D FaceApp, from Bellus3D inc, or TrueDepth camera system from Apple.

The digital geometric representation of the face or portions thereof may be used as a whole or spaced apart from only a portion of the overall representation used. Furthermore, portions of the geometry derived by scanning or other imaging techniques may be removed or edited from the digital geometric representation. The digital geometric representation data may be used without change, or the geometry of the representation may be changed. For example, digital processing may be used to alter the digital data. For example, the digital data may be altered 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 altered to provide a three-dimensional representation of the two-dimensional data.

In any embodiment of the present disclosure, any one or more of 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 execute one or more processors to perform the functions described herein. For example, in an embodiment, the digital geometric representation can be obtained by a user using a smartphone camera and/or a mobile application, and subsequently uploaded to a manufacturer's shared memory or medium for use in manufacturing the mask 100. In other embodiments, the digital geometric representation can 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, the lower eye region boundary 66 and the upper eye region boundary 68 are defined using a digital geometric representation. Various graphical programs can be used to obtain measurements and manipulations of the data in the digital geometric representation. For example, the Blender of the Blender Foundation can 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 eye region lower boundary 66 and the eye region upper boundary 68. A method according to an embodiment of the present disclosure includes defining at least two anchor points for an ocular opening 102. In some embodiments, the method may include defining more than two anchor points. For example, in embodiments, the method can include defining four anchor points corresponding to ocular region upper boundary 68, ocular region lower 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 a distance 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 eye region lower boundary 66. For example, the anchor point may be located about 0mm to about 10mm above the anchor point corresponding to the upper eye region boundary 68. In any implementation, the anchor points may be offset from the respective target features of the eye region by about 0mm to about 10 mm.

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 the 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, parabolas, 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 above-described shapes. In various embodiments, the junction can mimic, 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 connecting portion may simulate, follow or be parallel to the curvature of the eyebrows and eye folds or the eye shape. Such mimicking, conforming, or paralleling may help 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 numerical 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 points known in the art may be used. In embodiments using bezier curves, the curve may be digitally superimposed over the digital representation in the eye region 10, and the handle of the anchor point may be continuously adjusted until the curve follows the point of lowest curvature of the underlying eyeball 12 and intersects the anchor point.

Once the curve of the eye opening 102 is defined digitally, the data can be exported in any suitable file format for use in forming the mask 100. For example, a series of sections may be used to convert the curve into a grid that allows for 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 of 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 grid, about 30 to about 100 segments may be used. For example, the grid may be generated using about 30 to about 100 sectors, about 50 to about 100 sectors, about 30 to about 60 sectors, about 40 to about 80 sectors, or about 70 to about 90 sectors. 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 grid of curves defining the eye openings 102 is derived to a digital cutting tool and used as a cutting path to cut the eye openings 102 in the mask 100 material.

In other embodiments, the curved grid can be used to generate a digital geometric representation of the mask 100 in which the eye openings 102 will be formed, rather than cutting the eye openings 102 after the mask 100 is formed, which can 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, a digital printing device employing a method of forming the mask 100 material using various techniques (such as SLS, SLA, FDM, CLIP, and other additive manufacturing techniques known in the art) can be used. The defined curved grid of eye openings 102 can be incorporated into the grid of the mask 100 to digitally eliminate the mask 100 material in the eye openings 102, thereby defining a mask 100 with pre-shaped eye openings 102. In one embodiment, a grid of curves of the eye openings 102 can be digitally placed on the eyes of the facial grid defining the area of the mask 100 and extruded in the negative Z direction to intersect and pass through the facial grid. The intersection regions of the face mesh that entered the curve are selectively removed to define openings. Digital removal of a portion of the grid may be accomplished, for example, using boolean differentiation. The data associated with the mask 100 having the digital removal areas to define the customized eye openings 102 can then be exported to a suitable printing or manufacturing device to form the mask 100 itself.

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

The mask 100 can be a two-dimensional mask 100, or can be a three-dimensional mask 100, according to any embodiment of the present disclosure. The mask 100 can be made using any suitable technique, wherein the opening features defined by the methods disclosed herein can be incorporated. For example, methods according to embodiments of the present disclosure can be used to define a cutting path for cutting an opening into a pre-formed 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 can 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 can 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 can 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 automated, and various algorithms may be used. Additionally, the perspective of the image may be considered and/or measured to ensure data quality. The perspective correction may use a comparison of multiple images, phone sensor data, by guiding the user during acquisition of the images and any digital data, or otherwise.

The mask 100 having openings made according to the methods of embodiments of the present disclosure may include any suitable active, cosmetic, 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, a carrier, a base structure, an emulsion, a hydrogel, a binder, a processing aid (such as a thickener, rheology modifier, and the like). The active agent may also include a release layer to aid in the 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 an absorbent foam material that is placed according to a diagnostic scan or relative to an identifiable feature. For example, where it is desired to place the absorbent foam material along the cheekbones, brow or nose of the scanned user's mask 100, the placement location may be determined from the geometry of the representation rather than from a 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 other forms. 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, skin tightening agents, hair removal agents, hair regrowth agents, fungicides, antibacterial agents, antiviral agents, surfactants, cleansing agents, copper ion eluents (such as those from Cupron, Richmond, Va.), antioxidants, vitamins, sunscreens, rejuvenating agents, wound healing agents, sebum management agents, astringents, exfoliants, anti-inflammatory agents, leave-on agents, overnight treatments, dry skin treatments, pruritic skin treatments, cracked skin treatments, peptides, acne treatments, scar treatments, muscle soreness treatments, medications, including treating disease states or other acute or chronic problems such as eczema, rash, acne, cancer, cold sores, psoriasis, rosacea, vitiligo, warts, herpes, and the like, Pharmacologically active substances for fungal infections, actinic keratosis, ulcers, shingles, rashes caused by lacquers and insect bites. In addition, drugs that include pharmacologically active substances can be beyond local effects and are designed for transdermal delivery of the active substance into the bloodstream or other internal tissues. Examples of prescribed 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-make-up creams, lipsticks, lip liners, lip glosses, lip balms, lip pomades, pre-make-up lipsticks, lip pomades, concealers, foundations, loose powders, blushers, rouges/creams, highlights, bronze powders, mascaras, eyeliners and fixatives, fragrances, perfumes, or fragrance compositions (e.g., essential oils).

In one embodiment, the included one or more fragrances, perfumes, or fragrance compositions can be applied to the mask 100 for subsequent deposition to the face. However, a portion or all of the included one or more fragrance, perfume or fragrance compositions may be used as an experience agent. In use, the sensate provides an odor in the environment of the mask 100. For example, when applying a cosmetic to the face of a consumer/wearer, the scent provided by a fragrance that presents an outdoor garden scent may be desirable. The agent of experience need not be located on the target structure-contacting surface of the mask 100. The agent may be located in an area not in contact with the target structure, such as on a non-contact portion of the application side of the applicator or anywhere on any applicator side that is not in contact with the target structure. The experiential agent may be selected to accompany the selected appearance characteristic.

Examples

Example 1

An eye opening 102 cutting path is digitally formed using a method according to the present disclosure. Fig. 7A and 7B illustrate a mask 100 formed from the customized eye opening 102 developed.

Digital data corresponding to the three-dimensional mesh of the face is loaded into the Blender graphics program. The face mesh was 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 the captured texture/color information to provide supplemental information about where the fiducial points are located.

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

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

The bezier curve is converted to a grid and exported as a DXF file for XY laser cutters. The grid of the generated bezier curve has about 50 sections. The eye opening 102 is then cut in 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 eye openings 102 defined therein for direct printing of a facial mask having eye openings formed upon printing.

Eye openings 102 are then formed in the face mesh digitally 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 to a mesh having approximately 50 segments and extruded in the negative Z direction to the extent of intersecting and passing through the face mesh surface. Specifically, the bezier curve was initially 20mm above the eyes of the face mesh, and-50 mm was extruded to intersect the face mesh. A face mesh is then selected and boolean differentials from the extruded mesh eye opening cut paths are used to remove eye regions within the cut paths to leave defined eye openings in the face mesh. The resulting face mesh from which the eye openings have been removed can then be exported for direct printing.

Example 3

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

Four anchor points are selected on the digital geometric representation of the face presented as a mesh. The left anchor point 120 and the right anchor point 122 are set to be the midpoints of the outer nasal wall on either

side

46 and 48. The upper anchor point 118 is set to the center of the nose above the columella, 3mm above the highest point of the nostril 49. The lower anchor point 116 is set to the nasal center below the columella, 3mm below the base of the columella 44. The mesh is manipulated in the software at various angles to help define the anchor points.

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

The bezier curve is converted to a grid and exported as a DXF file for XY laser cutters. The grid of the generated bezier curve has about 50 sections. A laser cutter is then used to cut the nasal opening 114 in the mask material, thereby forming the nasal opening 114 shown in fig. 12.

side

Nose openings 114 are then digitally formed in the face mesh using bezier curves, and the mask is then directly printed, with the defined nose openings removed at the time of printing. The bezier curve is converted to a mesh having approximately 50 segments and extruded in the negative Z direction to the extent of intersecting and passing through the face mesh surface. Specifically, the bezier curve was initially 20mm above the nose of the face mesh and was extruded-50 mm to intersect the face mesh. A face mesh is then selected and the nose region within the cut path is removed using a boolean differential to the extruded mesh nose opening cut path to leave a defined nose opening in the face mesh. The resulting face 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 formed digitally using a method according to the present disclosure. Fig. 13 shows the mask 100 formed by the developed customized mouth opening 124.

Digital data corresponding to the three-dimensional mesh of the face is loaded into the Blender graphics program. The face mesh 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 the captured texture/color information to provide supplemental information about where the fiducial points are located.

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

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

The bezier curve is converted to a grid and exported as a DXF file for XY laser cutters. The grid of the generated bezier curve has about 50 sections. The mouth opening 124 is then cut in 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 mesh having mouth openings 124 defined therein for direct printing of a mask having mouth openings formed upon printing.

Mouth openings 124 are then formed digitally 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 to a mesh having approximately 50 segments and extruded in the negative Z direction to the extent of intersecting and passing through the face mesh surface. Specifically, the bezier curve was initially 20mm above the mouth of the face mesh and was extruded-50 mm to intersect the face mesh. A face mesh is then selected and the mouth region within the cut path is removed using a boolean differential to the extruded mesh mouth opening cut path to leave a defined mouth opening in the face mesh. The resulting face mesh from which the mouth opening has been removed can then be exported for direct printing.
