Face-Mapping, Theme-Based, Multi-Spot Skin Care Face Mask Kits for Children

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application No. 63/716,755, filed Nov. 6, 2024, entitled “Sprk Naturals Customizable Multi-Spot Kids Face Mask Kits: Fun, Safe, and Gentle Self-Care for Children Aged 2-14,” the entire contents of which are incorporated herein by reference for all purposes. Any terminology, figures, or embodiments disclosed in the provisional application shall be deemed incorporated and form part of the present disclosure.

FIELD OF THE DISCLOSURE

The present invention relates generally to cosmetic and personal-care devices, and more particularly to multi-spot, child-specific facial-mask systems configured to deliver skincare benefits in a playful, educational, and safe manner for children aged approximately four to fourteen years. The invention merges dermatological safety with experiential engagement, transforming traditional skincare into an age-appropriate, gamified self-care routine.

BACKGROUND

A sheet mask (also sometimes referred to as a facial mask, serum mask, hydrogel mask, or bio-cellulose mask) is a thin, pre-cut fabric or hydrogel sheet soaked in a serum and applied to the face of a human for a set time to hydrate, soothe, or treat the skin. These terms all refer to a single-use treatment sheet that conforms to facial contours to deliver active ingredients by contact.

Commercial sheet masks were developed for adults and are typically manufactured as full-face sheets saturated with serum. When such products are applied to a child, the sheet size and curvature are drastically mismatched to pediatric facial dimensions. The mask overlaps the eyes, nostrils, and mouth, forcing the user to sit still with restricted vision and airflow. Even when trimmed, the mask often folds or lifts, failing to adhere evenly. This poor fit leads not only to discomfort but also to uneven absorption and excessive serum run-off—a phenomenon in which excess liquid collects at the mask's lower edges and drips down the child's chin, neck, or clothing. Parents describe this as a messy, dripping application, and children frequently remove the mask within minutes out of frustration. In addition to these physical drawbacks, the formulations of adult masks typically contain active ingredients or concentrations intended for mature skin, such as strong exfoliants, retinoids, or high-strength hyaluronic acid complexes. When applied to the thinner and more permeable epidermis of children, these formulations can cause redness, sensitivity, or irritation. Thus, traditional adult sheet masks are both physically ill-fitting and chemically unsuitable for safe pediatric use.

Some manufacturers have attempted to adapt sheet masks for children by simply reducing size or printing cartoon faces on the mask surface. While these efforts make the masks more appealing visually, they do not solve the structural problems of oversaturation, air gaps, or dripping. A child's smaller facial radius demands not just scaling but segmentation: dividing the mask into multiple zones that each conform naturally to a local contour such as the forehead, cheek, or under-eye. Existing adult “sliced” masks—multi-piece patches shaped, for example, like slices of fruits or flowers—are not mapped to specific facial zones and are typically produced for adult skin in adult serum strengths. Furthermore, they lack any system of guidance or interactivity for self-application by children.

Therefore, there exists an unmet need for a customizable, child-specific, multi-spot face-mask system that: (1) fits the unique proportions and curvature of children's faces; (2) delivers gentle, dermatologically safe formulations; (3) avoids dripping or mess; and (4) engages children through playful design, visual mapping, and optional digital interactivity so that skincare becomes an enjoyable self-care activity shared with parents. The present disclosure addresses these needs.

DETAILED DESCRIPTION

Those of ordinary skill in the art will realize that the following description of the present invention is illustrative only and not in any way limiting. Other embodiments of the invention will readily suggest themselves to such skilled persons upon their having the benefit of this disclosure. Reference will now be made in detail to specific implementations of the present invention, as illustrated in the accompanying drawings. The same reference numbers will be used throughout the drawings and the following description to refer to the same or like parts.

The invention in certain embodiments introduces a customizable face-mapping multi-spot mask kit that replaces the one-piece adult sheet with several smaller, individually placeable patches. Each patch is pre-shaped and pre-infused to fit a distinct region of the child's face—forehead, under-eyes, and cheeks—and may optionally include a small chin or nose patch in certain sets. Each patch combines three elements: (a) a soft, child-safe substrate with superior conformability; (b) a mild, leave-on skincare serum optimized for children; and (c) a playful, theme-based ornamental shape that visually suggests its target zone (e.g., a rainbow arc for the forehead, clouds for under-eyes, hearts or fruit slices for cheeks).

The patches are deliberately sized to avoid overlapping sensitive regions while ensuring adequate coverage of key skin areas. Unlike a monolithic mask that collapses across the entire face, this modular design respects the facial freedom of a child—allowing them to talk, smile, snack, and breathe normally. The smaller elements adhere naturally due to serum surface tension and the flexible substrate, staying in place even as the child moves. Because each patch is lightweight and localized, it does not sag or drip, and the total serum load is precisely controlled to prevent runoff. Together, these aspects create a predictable, neat, and comfortable application.

In certain embodiments, the system includes face-mapping indicia, a visual guide that assists users in placing each patch on the correct zone. This indicia can appear as: (a) a printed diagram inside the package; (b) a reusable static-cling mirror decal (as shown in FIG. 3) bearing a character outline with icons numbered 1 through 3 for forehead, under-eye, and cheek zones, respectively; or (c) a themed insert printed with the same icons. Each version makes the application process intuitive and engaging for children.

FIG. 1 presents a perspective view of a representative embodiment of the invention in use. The illustration shows a child user (2) wearing a fruit-themed set of sheet-mask patches applied to mapped regions of the face. The figure exemplifies how the modular, multi-spot arrangement of patches conforms to the smaller facial geometry of children aged four to fourteen, leaving the user's eyes, nose, and mouth unobstructed for comfort, breathing, and communication.

As shown in FIG. 1, a single forehead patch (12), cut and printed in the shape of a stylized watermelon slice, spans the upper brow region along the frontal curvature of the child's forehead. The patch comprises a soft, flexible substrate layer that holds a measured quantity of a gentle skincare serum. The outer visible surface bears a bright watermelon pattern indicating the forehead zone within the fruit-theme design. The patch's tapered edges sit flush to the skin without lifting, showing the improved adherence achieved by the conformable materials used in certain embodiments.

Beneath each eye is positioned a respective under-eye patch (18a, 18b). These patches are semicircular and colored or printed to resemble kiwi slices. They occupy the sub-orbital regions directly below the lower eyelids, corresponding to the under-eye zones mapped in the system. Each under-eye patch shares the same structural composition as the forehead patch—namely, the substrate infused with the serum—but may optionally be fabricated from a hydrogel variant for added cooling and adhesion.

On both cheeks of the child appear two cheek patches (22a, 22b), each shaped as a small stylized strawberry in certain embodiments. The cheek patches target the malar skin region, one on the left cheek and one on the right, and represent the third mapped zone in the fruit-theme set. Their ornamental heart-like strawberry outlines contribute to the playful aesthetic while maintaining functional surface area for hydration and skin conditioning.

Collectively, the forehead patch (12), the paired under-eye patches (18a, 18b), and the paired cheek patches (22a, 22b) form a multi-spot arrangement covering the principal treatment zones—forehead, under eyes, and cheeks—while leaving intervening regions clear. The patches are evenly spaced so that none overlap or interfere with facial expression. The air gaps characteristic of oversized one-piece masks are eliminated; each patch conforms closely to the child's curved surfaces, demonstrating the system's ergonomic advantage.

In summary, FIG. 1 visually communicates the principal concept of the invention in certain embodiments: a customizable, child-sized, themed, multi-spot facial mask kit that maintains comfort and playfulness while demonstrating correct placement of the patches on mapped facial zones. The figure emphasizes how the smaller individual patches adhere neatly to targeted skin areas, preserve open sensory regions (eyes, nose, mouth), and produce an organized, mess-free, and visually engaging application consistent with the purposes of the invention.

FIG. 2 is an exploded perspective view illustrating the principal packaging elements of the multi-spot face-mask kit (10) in certain embodiments. The components are arranged in sequence from top to bottom to depict the relationship among the individual patch sachets (30a-30c), the outer pouch (26), and the printed face-mapping card (25).

At the top of the illustration, three separate sealed patch sachets (30a, 30b, 30c) are shown in partial overlap. Each sachet contains one or more sheet-mask patches corresponding to a specific facial region that were shown in FIG. 1—namely a forehead patch (12), two under-eye patches (18a, 18b), and two cheek patches (22a, 22b). The sachets are fabricated from a multilayer laminate film providing both moisture and oxygen barrier protection to maintain serum hydration. The sachets are hermetically sealed along three or four edges and may incorporate tear notches for ease of opening. Each sachet is labeled externally with a thematic icon (e.g., a watermelon slice, kiwi, or strawberry) identifying the type of patch and its intended zone. In production, in certain embodiments these sachets are assembled in separate manufacturing runs—forehead and cheek patches using cotton substrates, under-eye patches using hydrogel—and are then combined during final kit assembly.

Beneath the individual sachets in FIG. 2 is the outer pouch (26). The outer pouch is a resealable envelope, such as a zip-lock or heat-seal bag, that houses all individual sachets and printed materials. The pouch is constructed from flexible, cosmetic-grade laminate film (for example PET/AL/PE) to preserve freshness and hygiene during shipping and storage. The outer pouch bears product and theme labeling, such as Fruit Spa Series, and an optional machine-readable code (QR or NFC tag 24) used to launch the “Scan-to-Spa Journey” digital guidance described with respect to FIG. 4. The outer pouch (26) therefore functions both as primary protective packaging and as a carrier for branding, regulatory information, and the digital interactivity feature. Certain embodiments do not include outer pouch (26), and certain kits may include different components (e.g., one kit may omit the outer pouch and include three full sets of masks, such as three forehead masks, six under-eye masks, and six cheek masks).

In certain embodiments, beneath the pouch is positioned the face-mapping card (25), which provides printed instructions for correct patch placement. The card includes a simplified line illustration of a child's face with three numbered regions—(1) forehead, (2) under-eyes, and (3) cheeks—corresponding to the patch sachets (30a, 30b, 30c). The card may be printed on coated paperboard or thin plastic sheet stock, sized approximately 90×130 mm to fit within the pouch. The card may alternatively serve as a collectible insert; in themed sets, multiple cards with varying characters (e.g., unicorn, panda, mermaid) can be rotated across production batches to enhance play value.

During assembly, the sachets (30a, 30b, 30c) are first filled and sealed, then inspected for weight and seal integrity. The sealed sachets are collated together with one printed face-mapping card (25) and inserted into the outer pouch (26). The pouch is then sealed, optionally with a tamper-evident tear strip. In certain retail configurations, a hang-hole header or folded box may surround the pouch for shelf display. All materials are recyclable or biodegradable in certain embodiments, ensuring environmental compliance.

In summary, FIG. 2 demonstrates the modular packaging architecture that enables hygienic separation of different patch types while preserving thematic unity in the final kit. The exploded depiction shows how the child receives a single, cohesive kit (10) that contains three distinct facial-zone sachets (30a, 30b, 30c), an informational face-mapping card (25) for guidance, and an outer pouch (26) that ties the set together as a ready-to-use, child-friendly spa experience.

In certain embodiments each patch substrate 14 is manufactured from a biodegradable, dermatologically tested material selected from 100% cotton non-woven, bamboo viscose, Tencel (lyocell), Cupra (regenerated cellulose), bio-cellulose, or hydrogel. Fabric substrates range from 0.12 to 0.40 mm thick; hydrogel versions from 0.25 to 0.6 mm. The patch adheres naturally through moisture cohesion and surface tension; no adhesive or peel tab is used or required in certain embodiments. This not only simplifies manufacture but preserves the clean visual integrity of the patch's playful shape—for example, a unicorn without an unsightly arrow or tab disturbing its appearance. Children remove the patch simply by lifting one edge after treatment; the substrate detaches cleanly without residue.

Prior to die-cutting, each substrate sheet may be pre-moistened with serum to increase tackiness and air displacement during application. Slightly pre-hydrated Cupra and Tencel fabrics naturally conform to child curvature, eliminating air pockets without chemical adhesives. Optional use of low-modulus hydrogel films or addition of 0.05-0.15% polysaccharide thickeners (e.g., xanthan gum or trehalose) to the serum enhances cohesion and bubble-free laydown. All edges are beveled in certain embodiments to a soft radius so the patch feels imperceptible once applied—an important psychological factor for young users sensitive to texture or edges. The resulting construction combines predictable manufacturability with a smooth, aesthetic surface finish compatible with existing mask-production lines.

Each patch carries a metered volume of a child-tuned leave-on serum 16. This formulation is designed to provide hydration and barrier support without dripping or residue. The serum's viscosity is adjusted so that it lightly coats the substrate fibers yet remains cohesive during the entire application period. When the patch is placed on skin, the serum diffuses gradually across the contact interface, ensuring steady absorption instead of pooling or running.

The active ingredients in certain embodiments are selected from safe, low-concentration actives validated for pediatric use. Typical ingredients in certain embodiments include 0.05-0.3% sodium hyaluronate for lightweight hydration; 0.001-0.005% Centella asiatica extract for soothing and barrier repair; and botanical extracts such as aloe vera, chamomile, cucumber, green tea, and oat (each 0.05-1%) for calming and antioxidant support. Humectants like glycerin and panthenol (1-3%) maintain moisture balance, while trace preservatives such as 1,2-Hexanediol or Ethylhexylglycerin (<0.8%) assure microbial stability. In certain embodiments, all ingredients are EWG 1-2 rated, paraben-free, phthalate-free, alcohol-free, and fragrance-free. The pH is maintained between 5.0 and 5.5 to match the natural acid mantle of child skin. Because the serum is rinseless and non-sticky, children can resume normal activity immediately after use without residue or tightness.

Manufacturing is accomplished on existing sheet-mask production lines with minor die-cut modifications. Each facial-zone type—forehead, cheek, and under-eye—is produced in certain embodiments in a separate run to accommodate different substrates and serum viscosities. For example, the forehead and cheek patches are cotton or bamboo-based in certain embodiments, while the under-eye patches are hydrogel. After cutting and soaking, in certain embodiments patches are immediately sealed within individual foil sachets to prevent drying. A final assembly step combines the sachets into a single outer pouch or retail box constituting the complete kit 10.

Packaging formats in certain embodiments include (a) single-use sets for home spa sessions and (b) multi-set boxes for spa party use with multiple children. Each sachet is printed with matching icons corresponding to the face-mapping guide in certain embodiments—for instance, a watermelon icon on the forehead packet or cloud icons on the under-eye packets. In certain embodiments, moisture-barrier laminates and cosmetic-safe inks ensure freshness and safety. Factory QC includes serum weight uniformity (±5%). Some substrates are biodegradable in certain embodiments.

As shown in FIG. 2, the kit in accordance with certain embodiments includes schematic face-mapping indicia (25). In certain embodiments, the indicia includes numbered icons—(1) for forehead, (2) for under-eyes, and (3) for cheeks—illustrating the correspondence between patch shapes and zones. In practice, this indicia may appear in certain embodiments on an insert card, a static-cling decal configured for a mirror surface, or a digital display, as described elsewhere herein.

In certain embodiments, the face-mapping guide is a removable, reusable static-cling decal configured to adhere without adhesive to a smooth mirror surface by electrostatic attraction. The decal may be formed from transparent or semi-transparent electrostatic vinyl (static-cling PVC) or electrostatic PET suitable for humid bathroom environments. In alternative embodiments, a reusable low-tack silicone adhesive film may be employed for non-glass substrates. The guide functions as a child-friendly visual template indicating where each patch belongs. In some embodiments, the guide depicts a cartoon character—for example, a unicorn, panda, or mermaid—rendered in light outlines so the child's reflection remains visible through the artwork. Icons mark each zone—a star at the forehead region, clouds beneath the eyes, and hearts at the cheeks—and, in use, the child may align their reflection to the outline and apply the corresponding patches to the matching positions, thereby transforming placement into a playful, self-guided activity.

Each placement indicia in certain embodiments may include simple prompts (“Place your stars on your forehead!” or “Give your unicorn some cheek sparkles!”) and motivational phrases (“You're glowing like a unicorn!”). Collectible sets may feature different characters and quotes for educational and decorative variety. Parents can reuse or swap them as part of the unboxing experience.

FIG. 3 illustrates a representative embodiment of face-mapping indicia (25) used for guiding placement of the facial mask patches described in connection with FIGS. 1-2. The indicia may be fabricated as either a mirror-cling decal or a printed postcard insert depending on kit configuration and target price point. In either case, the indicia provides intuitive, child-friendly visual guidance to show where each patch should be applied on the user's face.

The illustrated indicia sheet (25) is shown as generally rectangular, measuring approximately 90×130 mm for postcard embodiments or 150×200 mm for mirror-cling embodiments. The sheet bears a character outline (30)—such as a stylized unicorn, panda, or mermaid—positioned to correspond to the typical proportions of a child's face. Within the outline, placement icons are printed to denote the correct locations for the respective facial zones:

• • (1) a star icon on the forehead region (34) corresponding to the forehead patch;
  • (2) two cloud icons under the eye regions (36a, 36b) corresponding to under-eye patches; and
  • (3) two heart icons over the cheek regions (38a, 38b) corresponding to cheek patches.

In embodiments where the indicia sheet (25) is implemented as a mirror cling, the material is a transparent or semi-transparent static-cling vinyl or electrostatic PET film that adheres to smooth mirror surfaces through static charge rather than adhesive. The transparency enables the child user to align their reflection with the printed outline, effectively “fitting” their face within the guide. When used in this manner, the indicia sheet acts as a reusable visual stencil for proper mask placement. The cling can be repositioned multiple times without residue and is safe for bathroom humidity conditions.

In postcard-style embodiments, the indicia sheet (25) is printed on a coated paperboard or synthetic stock and included loose within the outer pouch (see FIG. 2). The postcard variant features the same printed character outline and numbered placement icons but is intended to be propped near the mirror rather than adhered to it. This version may also carry a brief written instruction sequence such as: “1—Place your watermelon on your forehead; 2—Clouds under your eyes; 3—Strawberries on your cheeks!” The printed card may further include a motivational phrase (46) (“You're glowing like a unicorn!”) or collectible identifiers corresponding to the theme set.

The indicia sheet (25) may also include a machine-readable code (24), such as a QR symbol printed in one corner, which links directly to the digital “Scan-to-Spa Journey” described with respect to FIG. 4. This dual-function arrangement allows the physical indicia to serve as both a teaching aid and an entry point into the interactive tutorial.

As depicted, FIG. 3 demonstrates that the indicia sheet (25) provides multiple design options—transparent static cling for direct mirror application or printed card for off-mirror use—while maintaining consistent instructional iconography for the mapped facial zones. The labeled elements collectively illustrate the hybrid instructional role of the indicia sheet: enabling correct patch placement, promoting self-guided application, and reinforcing the playful thematic design that characterizes the children's face-mask kit.

To complement the physical mapping guide, in certain embodiments the kit includes a digital experience accessible through a QR code or NFC tag 24 printed on the outer pouch. Scanning the code launches a mobile-friendly web application introducing the child to the “Scan-to-Spa Journey.” An animated “Unicorn Coach” appears on screen with a cheerful greeting and step-by-step visual tutorial. The interface features large buttons, bright colors, and voice prompts for pre-readers. Within 90 seconds, the coach demonstrates how to open each sachet and place the patches on zones numbered 1 through 3.

Once the patches are in place, the sound module of the application in certain embodiments announces “Spa time starts now!” and encourages the child to relax and spend the next ten minutes bonding with a parent or sibling. No further screen interaction is required during this period; the goal is to foster connection and mindful rest. At the end of the session, a simple animation awards a digital “Spa Star” badge that can be collected or printed on the next package. Optional augmented-reality (AR) elements may project floating stars or sparkles around the child's face through the phone camera for brief entertainment at the start of the routine. In certain embodiments all content complies with children's online privacy standards and is optimized for use by ages four and up.

FIG. 4 depicts the digital “Scan-to-Spa Journey” interface (40) in accordance with certain embodiments, displayed on a representative mobile device (42). The illustration demonstrates how the child user interacts with the digital portion of the system, which complements the physical face mask kit described in FIGS. 1-3. The interface guides the user through patch application and provides encouragement, timing, and rewards in a gamified, child-appropriate manner.

The mobile device (42) is shown in front view with a rectangular display screen (44), side bezels, and a speaker opening. The graphical user interface (GUI) rendered on the display represents the animated onboarding experience that begins when the child scans the QR code (24) printed on the kit's outer pouch or face-mapping sheet (see FIGS. 2 and 3). Upon scanning, the child is directed to a secure web-based or app-based environment that opens the “Scan-to-Spa Journey” module.

Prominently displayed at the top of the screen in certain embodiments is the title banner (46) reading “Welcome to Your Scan-to-Spa Journey!” Beneath the banner appears a cartoon avatar of the Unicorn Coach (48), a friendly animated guide that introduces the process and encourages the child with positive voice prompts and visual cues. The Unicorn Coach character may blink, wave, or display sparkles around its horn to maintain engagement during instruction. The animation is designed to run at a gentle pace and uses warm pastel tones and soft outlines consistent with the brand's theme.

In the center of the display is a simplified facial diagram (58) showing the patch placement zones, matching the numbering system from the physical indicia sheet (25). Icons corresponding to the patch shapes—star (forehead), clouds (under-eye), and hearts (cheeks)—may briefly illuminate as the coach describes each step. A graphic (56) indicates the recommended application order. Under the diagram is a start button (58) labeled “BEGIN SPA TIME,” rendered as a large, rounded rectangle for easy tapping by small fingers.

When the start button (58) is tapped, in certain embodiments the interface transitions into a timer display (50) that counts down approximately 10 minutes of treatment time. A subtle musical background and intermittent affirmations (“You're glowing already!” or “Hold still for your stars to shine!”) may be played by the coach avatar (48). Animated sparkles may float across the screen to hold attention without overstimulation. In certain embodiments, the timer display (50) may include a remaining-time indicator.

Upon timer completion, the application advances to the reward screen (66) featuring a large “Spa Star Badge” (66) graphic. The badge may take the form of a cartoon medallion surrounded by stars and ribbons, and includes the text “Spa Star—Great Job!” The reward screen (66) may further display a completion button (70) enabling the parent or child to log the session or unlock a digital sticker for later printing or sharing. The system may track earned badges to reinforce consistent skincare habits and provide an evolving collection as part of the kit's broader educational and behavioral reinforcement framework.

The bottom portion of the GUI includes navigation icons in certain embodiments, s shown in FIG. 4, allowing the user to replay the introduction, view collected badges, or exit. The application architecture (not shown in detail) is designed in certain embodiments for minimal data capture, ensuring that the interaction remains private, child-safe, and free of advertising. Network activity is limited to retrieving animation assets and timer synchronization data from a secure server.

As depicted, FIG. 4 demonstrates how the digital component of the invention extends the tangible kit experience into an interactive educational tool. The combination of the mobile device (42), the Scan-to-Spa Journey interface, and the Unicorn Coach (48) character creates a guided self-care activity that is both entertaining and instructive. The child learns proper patch placement and timing while receiving positive reinforcement through the visual “Spa Star” reward system, thereby promoting early self-care habits and confidence in a safe, age-appropriate environment.

In certain embodiments each kit is available in one or more themes, for example: Fruit (Watermelon/Kiwi/Strawberry), Princess (Crown/Wand/Heart), Mermaid (Seashell/Tail/Pearl), Animal-corn (Panda-corn, Llama-corn), Holiday (Xmas or Halloween), and Neon Party. Children may mix patches from different themes while still following the same zone-mapping system. Every design is dimensioned so that even when mixed, the patches fit comfortably without overlap.

To use the kit in certain embodiments, the caregiver or child cleanses the face with a gentle cleanser. The child opens each sachet in sequence, referring to the mirror-cling guide or the digital tutorial. The forehead patch is placed first, followed by the under-eye and cheek patches. The child aligns the patches with the illustrated zones or numbered icons. Upon application, the Unicorn Coach prompt “Spa time starts now!” signals the start of the ten-minute bonding period. During this time, children may read, listen to music, or converse with parents—screens are set aside.

After ten minutes, either the color indicator (if present) changes or a parent announces completion. The child peels off each patch starting from one edge and discards it. Residual serum is patted into skin without rinsing. The skin feels soft, hydrated, and comfortable. All components are single-use and biodegradable.

Certain embodiments thus combine safety, fit, and fun in a way. Child-specific geometry eliminates dripping; mild formulation prevents irritation; interactive guidance promotes self-care education. The mask kit in certain embodiments thus bridges dermatology and child development by offering a predictable, comfortable, and engaging experience.

While the above description contains many specifics and certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of, and not restrictive on, the broad invention, and that this invention is not to be limited to the specific constructions and arrangements shown and described, since various other modifications may occur to those ordinarily skilled in the art, as mentioned above. The invention includes any combination or sub-combination of the elements from the different species and/or embodiments disclosed herein.
