Applicators and cases for artificial lash extensions

FIELD OF THE INVENTION

0001Various embodiments concern cases for housing artificial eyelashes and applicators for applying artificial eyelashes to the underside of an individual's natural eyelashes.

BACKGROUND

0002Eyelash extensions have conventionally been used to enhance the length, thickness, and fullness of natural eyelashes. Eyelash extensions, however, must be applied to an individual's natural eyelashes one by one to avoid having the eyelash extensions stick together. Consequently, lash extension services can cost hundreds of dollars depending on the type and number of lashes used, the skill of the cosmetician, and the venue where the eyelash extensions are applied. It usually takes an experienced cosmetician one to two hours to attach a full set of eyelash extensions.

0003Clusters of artificial lashes have conventionally been used to enhance the length, thickness, and fullness of an individual's natural eyelashes. However, each cluster must be applied to the individual's eyelashes individually in order to avoid having the clusters of artificial lashes stick together and to ensure multiple clusters are evenly distributed across the width of the individual's lash line.

0004Alternatively, false eyelashes may be applied directly to an individual's eyelid. False eyelashes come in strips (and thus may also be referred to as "strip lashes") that can be trimmed to fit the width of the individual's eyelid. While a strip of false eyelashes can be applied in a single motion, false eyelashes are easily distinguishable from the individual's natural eyelashes and may be uncomfortable when worn for extended periods of time.

0006The figures depict various embodiments for the purpose of illustration only. Those skilled in the art will readily recognize that alternative embodiments may be employed without departing from the principles of the present invention. The claimed subject matter is intended to cover all modifications, equivalents, and alternatives falling within the scope of the present invention as defined by the appended claims.

DETAILED DESCRIPTION

0007Conventional eyelash extensions (or simply "lash extensions") are individually adhered to an individual's natural eyelashes one-by-one in order to prevent the eyelash extensions from sticking together. However, because the average individual might have anywhere from thirty to eighty natural lashes per eye, the application process can take several hours to attach a full set of lash extensions.

0008Introduced here are cases for housing sets of artificial lash extensions that can be applied to an individual's natural lashes. Each set of artificial lash extensions can include multiple lash fusions, and each lash fusion can include multiple clusters of artificial lashes. These clusters include multiple artificial hairs made of natural materials (e.g., silk or authentic mink hair) or synthetic materials (e.g., acrylic resin, polybutylene terephthalate (PBT), or synthetic mink hair made of polyester). A cluster of artificial lashes generally includes approximately 10 to 30 artificial hairs (and preferably 10 to 20 artificial hairs). While certain embodiments have been described in the context of lash fusions that include multiple clusters, those skilled in the art will recognize that a lash fusion could also include a series of individual artificial hairs that are connected to one another.

0009Multiple clusters of artificial lashes are often formed into bundles called "lash fusions." The base of a lash fusion (e.g., where multiple clusters are fused together) is intended to be affixed to an individual's natural lashes. A lash fusion may be approximately 4-8 millimeters (mm) wide. A lash fusion could also include 3-10, 3-7, 5-10, 5-7, or 4-6 clusters. Accordingly, a lash fusion could include 30-150, 30-120, or 30-90 individual artificial hairs. A set of artificial lash extensions can then be formed by positioning multiple lash fusions next to one another in an arrangement that substantially matches the curvature of the upper tightline along the base of the eyelid.

0010While the multiple lash fusions included in a set of artificial lash extensions are typically not connected to one another (e.g., are not fused together using heat, an adhesive, etc.), the entire set of artificial lash extension can be applied to the underside of the individual's natural lashes in a single motion by an applicator. Thus, the multiple lash fusions in a set of artificial lash extensions may be arranged to match the curvature of an eyelid, as well as an applicator designed to facilitate fixation of the entire set of artificial lash extensions to an individual's natural lashes. A set of artificial lash extensions could include 3-8, 3-5, 5-8, or 4-6 lash fusions. Accordingly, a set of artificial lash extensions could include 150-360 individual artificial hairs.

0011Also introduced here are applicators for resiliently grasping the multiple lash fusions in a set of artificial lash extensions, and then simultaneously applying the multiple lash fusions along the upper tightline in a single motion. As shown in <figref idref="f0001"><b>FIG. 1</b></figref><b>,</b> the upper tightline is interposed between the upper lash line and the upper waterline. An applicator includes opposed arms that are connected to one another at an inner end (also referred to as the "proximal end") that is gripped by an individual. The applicator can also include an outer end (also referred to as the "distant end" or the "distal end") having a concave (e.g., crescent) shape that is contoured to be substantially flush with the convex shape of the upper tightline. The concave shape of the applicator may also substantially complement the predefined indentations within cases that are responsible for holding sets of artificial lash extensions. Applicators are often comprised of metal (e.g., stainless steel, hardened steel, or titanium) to increase the durability and grasping precision of the opposed arms.

0012An adhesive may be applied to the top of each lash fusion in a set of artificial lash extensions during the manufacturing process, which enables an individual to easily apply the set of artificial lash extensions directly to the underside of the natural lashes rather than to the eyelid. Additionally or alternatively, the individual could apply an adhesive before applying the set of artificial lash extensions to the underside of the natural lashes. For example, the individual may apply an adhesive to each lash fusion before applying the set of artificial lash extensions to the natural lashes. As another example, the individual may apply an adhesive directly to the natural lashes. Thus, the adhesive could be a waterproof glue or mascara.

<u>Terminology</u>

0013Brief definitions of terms, abbreviations, and phrases used throughout this application are given below.

0014Reference to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosure. The appearances of the phrase "in some embodiments" are not necessarily referring to the same embodiment, nor are they necessarily referring to separate or alternative embodiments that are mutually exclusive of one another.

0015The terms "connected," "coupled," or any variant thereof includes any connection or coupling between two or more elements, either direct or indirect. The coupling or connection between the elements can be physical, logical, or a combination thereof. For example, two components may be coupled directly to one another or via one or more intermediary channels/components. The words "associate with," meanwhile, mean connecting or relating objects, items, etc.

<u>System Topology Overview</u>

0016<figref idref="f0002"><b>FIG. 2</b></figref> depicts clusters of artificial lashes that can be used by professional lash technicians and cosmeticians. Each cluster of artificial lashes includes multiple artificial hairs that consist of natural materials (e.g., silk or authentic mink hair) or synthetic materials (e.g., acrylic resin, PBT, or synthetic mink hair made of polyester).

0017Clusters of artificial lashes typically include 10 to 30 artificial hairs that are heated (e.g., as part of a holt melt process) and then secured to one another. For example, in some embodiments linear artificial hairs are heated at one end such that they begin to fuse to one another at that end, while in other embodiments linear artificial hairs are heated near a central point and folded underneath one another.

0018In some embodiments, some or all of the artificial hairs in a cluster may be tied to a support thread (i.e., knotted). The artificial hairs may be tied by any such means, such as a slip know that prevents horizontal spreading of the cluster.

0019<figref idref="f0003 f0004"><b>FIGS. 3A-B</b></figref>depict how a set of artificial lash extensions can be affixed to the underside of an individual's natural lashes. More specifically, <figref idref="f0003"><b>FIG. 3A</b></figref> is a perspective view of a set of artificial lash extensions from above, while <b>FIG. 2B</b> is a view of the set of artificial lash extensions from below.

0020A set of artificial lash extensions can include multiple lash fusions that are arranged to match the curvature of the upper tightline of an eyelid. For example, multiple lash fusions may be arranged such that the inner ends (i.e., the bases) form a concave shape that substantially complements the universal tightline of nearly any human eye. In some embodiments, sets of artificial lash extensions preferably include 5-7 distinct clusters of artificial lashes. The number of lash fusions in each set (as well as the number of clusters in each lash fusion) may be based on the thickness of the artificial hair used, the desired style of the eyelid on which the set is intended to be affixed, the desired lash density (also referred to as the "fullness" of the individual's lashes), etc. As shown in <figref idref="f0004"><b>FIG. 3B</b></figref><b>,</b> the set of artificial lash extensions is aligned with the tightline rather than the lash line, and then affixed to the underside of the natural lashes. Said another way, the set of artificial lash extensions is applied directly to the underside of the natural lashes rather than to the eyelid.

0021An adhesive can be applied to the top of each lash fusion in the set of artificial lash extensions, which enables an individual to easily apply the entire set directly to the natural lashes. The individual responsible for applying the set of artificial lash extensions could be a person who affixes the multiple lash fusions to herself or some other person (e.g., a professional lash technician or a cosmetician). In some embodiments, the adhesive is applied when each lash fusion and/or the set of artificial lash extensions are initially manufactured. Additionally or alternatively, the individual could apply an adhesive before attaching the set of artificial lash extensions to the natural lashes.

0022The adhesive could be a waterproof (semi-permanent) glue, mascara, or some other co-polymer solution having an adhesive quality. Although latex-based adhesives are generally avoided to avoid irritation of the individual's eyelid (e.g., due to an allergic reaction), adhesives can include various other natural and/or chemical ingredients. Examples of possible adhesives include: <ul id="ul0002" list-style="bullet"><li>Arcrylates/ethylhexyl acrylate copolymer, aqua, propylene glycol, ceteareth-25, hydrogenated castor oil, glycerin, phenoxyethanol, 2-bromo-2-nitropropane-1, 3-diol, methylcholoroisothiazolinone, methylisothiazolinone, methylparaben, and optionally a color agent (e.g., black 2 (Cl 77266));</li><li>Polyterpene, styrene/isoprene copolymer, petrolatum, polyisobutene, microcrystalline wax (cera microcristalina, cire microcrystalline), hydrogenated styrene/methyl styrene/indene copolymer, styrene/VA copolymer, and optionally an antioxidant (e.g., butylated hydroxytoluene <b>(BHT));</b></li><li>Chlorine dioxide, p-anisic acid, biotin, lavandula angustifolio oil, propylene glycol, water, 2-ethylhexyl acrylate, and optionally a preservative (e.g., benzalkonium chloride); and</li><li>Acrylate copolymer and water.</li></ul>

0023Those skilled in the art will recognize that many other adhesive compositions are possible and, in fact, may be desirable for individuals having certain allergies, desiring certain fixation duration (also referred to as "permanency" of the lash extensions), etc.

0024Semi-permanent clusters of lash extensions may be applied with a Federal Drug Administration-approved (FDA-approved) adhesive that achieves a strong bond. Such adhesives generally include cyanoacrylate. Different types of cyanoacrylates (e.g., ethyl, methyl, propyl, butyl, and octyl) have been designed for bonding to different surfaces. For example, adhesives made from methyl-2-cyanoacrylateare are designed to bond a smooth surface (e.g., the lash extension) to a porous surface (e.g., the natural eyelash), but not on the skin as it may cause irritation.

0025<figref idref="f0005 f0006 f0007"><b>FIGS. 4A-C</b></figref>depict several different views of a case 400 for holding artificial lash extensions. <figref idref="f0005"><b>FIG. 4A</b></figref> is a perspective view of the case 400, while <figref idref="f0006"><b>FIG. 4B</b></figref> is an exploded view of the case 400 in which the upper cover 402 has been removed to expose multiple predefined indentations 404 within a base assembly 406.

0026The case 400 may include a base assembly 406 and an upper cover 402 that partially or entirely shields the predefined indentations 404. In some embodiments, the base assembly 406 includes one or more fastener holes 408 that allow fasteners to be used to attach the upper cover 402 to the base assembly 406. One example of a fastener is a fastener boss 410. Other embodiments may provide other means of attachment, such as hidden snaps, latches, detents, ridges, magnets, etc.

0027The base assembly 406 and/or the upper cover 402 may be partially or entirely composed of metal, plastic, or some other material (e.g., foam). For example, in some embodiments the base assembly 406 includes a die case metal body (e.g., for strength and durability) having a smooth powder coating (e.g., for aesthetics and improved cleanability), while in other embodiments the base assembly 406 includes a recyclable (i.e., disposable) plastic body that is not intended for significant durations of use (e.g., months or years). Those skilled in the art will recognize that any suitable material may be used. For example, in some embodiments plastic may be desirable because it is recyclable and resistant to the adhesives typically applied to lash fusions before fixation to an individual's natural lashes.

0028Moreover, the outer surfaces of the base assembly 406 and/or the upper cover 402 may be substantially smooth and continuous. Thus, the outer surfaces of these components may be substantially free of any gaps, ridges, or fasteners that would make cleaning difficult or that may inadvertently capture artificial lashes.

0029<figref idref="f0007">FIG. 4C</figref> illustrates how multiple lash fusions in a set of artificial lash extensions can be positioned within the case 400 in a specified arrangement. While the multiple lash fusions in the set of artificial lash extensions will typically not be connected to one another, the multiple lash fusions can be arranged such that the set as a whole substantially complements the shape of an eyelid. More specifically, the curvature of the multiple lash fusions may substantially match the tightline curvature of an average person. Thus, an entire set of artificial lash extensions may become substantially flush with the lash line when the set is arranged proximate to the tightline.

0030The predefined indentations 404 allow the lash fusions to be positioned in a specific arrangement. For example, the curvature of the outer surface of the case 400 may cause the lash fusions to be arranged in the shape of an eyelid (i.e., the outer surface of the case 400 may mimic the natural lash line). Together, the multiple lash fusions form a set of artificial lash extensions that can be collectively applied in a single motion.

0031<figref idref="f0008 f0009"><b>FIGS. 5A-B</b></figref>depict an applicator 500 that can be used to simultaneously apply an entire set of artificial lash extensions to an individual's natural lashes. <figref idref="f0008"><b>FIG. 5A</b></figref> is a perspective view of an applicator 500 having two opposed arms, and <figref idref="f0009"><b>FIG. 5B</b></figref> is a side view depicting the curvature of the applicator 500.

0032The applicator 500 includes opposed arms 502a-b that are connected to one another at an inner end (also referred to as a "proximal end"). Each of the opposed arms 502a-b can include an inner portion 504 that is gripped by an individual and an outer portion 506 that is contoured to resiliently grasp multiple lash fusions. For example, the outer portion 506 may have a concave (e.g., crescent) shape 508 that enables the applicator 500 to become substantially flush with the housing of a case (e.g., case 400 of <figref idref="f0005 f0006 f0007"><b>FIGS. 4A-C)</b></figref>and the tightline of an eye. This nonlinear shape enables the individual to readily grasp and apply an entire set of artificial lash extensions without requiring assistance from another individual (e.g., a medical professional or cosmetician).

0033In some embodiments, the middle portion 510 (also referred to as the "bridge) of the applicator 500 includes another concave shape 512 (also referred to as a "hump") that allows the applicator 500 to rest on the individual's cheek bone, nose bridge, etc. For example, if the individual is holding the applicator 500 in their right hand, then the individual can readily apply a set of artificial lash extensions to the right eye. However, when the individual attempts to apply a set of artificial lash extensions to the left eye, the individual may to balance the hump 512 on the bridge of the nose for stabilization. During the application process, the individual may grasp the inner portion 504 and/or the middle portion 510.

0034The applicator 500 can be composed of metal, plastic, or any other suitable material. Metal alloys (e.g., stainless steel) are typically preferred because they provide greater durability and allow the applicator 500 to have high precision. The term "precision" refers to the size of objects that can be grasped by the applicator 500. Highly precise grasping tools (e.g., tweezers) can grab very small objects. In order to have high precision, the opposed arms 502a-b must be precisely aligned and balanced so that an individual can grasp individual artificial lashes.

0035The outer portions 506 of the opposed arms 502a-b are arranged to engage one another when the inner portions 504 of the opposed arms 502a-b are pressed toward one another by an individual. Such action causes pressure to be applied to the exterior surface of the inner portions 504 and/or the middle portions 510 of the opposed arms 502a-b. <figref idref="f0010"><b>FIG. 6A</b></figref> depicts how the arrangement of a set of artificial lash extensions enables all of the lash fusions to be simultaneously grasped by an applicator. More specifically, an individual or a healthcare professional, such as a lash technician or cosmetician, can grasp an entire set of artificial lash extensions using the applicator, and then simultaneously apply the entire set of artificial lash extensions to the individual's natural lashes in a single motion.

0036<figref idref="f0011"><b>FIG. 6B</b></figref> depicts how the concave shape of an applicator can substantially complement the convex shape of a case. The concave shape of the applicator enables an individual to simultaneously grasp all of the lash fusions in a set of artificial lash extensions housed within the case. After grasping the set of artificial lash extensions, the individual can apply the entire set of artificial lash extensions to the natural lashes in a single motion.

0037The individual may also exploit the concave shape of the applicator to apply pressure to the multiple lash fusions to ensure that each lash fusion is securely attached to the natural lashes. For example, after applying the set of artificial lash extensions to the underside of the natural lashes, the individual can apply pressure another time to clamp down on the natural lashes and the artificial lash extensions. While the second application of pressure may not be necessarily, the individual may perform such action to ensure adherence of the lash fusions to the natural lashes.

0038In some embodiments, one or both of the opposed arms include a knurl at the outer end that can be used to aid in grasping. However, the knurl(s) must be offset from one another so that the outer portions of the opposed arms can be pressed against one another. Embodiments may also include a ridge that extends around some or all of the periphery of each opposed arm

0039Although the term "individual" is generally used to refer to a person who applies sets of lash extensions to herself, those skilled in the art will recognize the technology described herein can also be used by healthcare professionals, cosmeticians, etc.

0040<figref idref="f0012"><b>FIG. 7</b></figref> depicts a flow diagram of a process 700 for applying a set of artificial lash extensions to an individual's natural lashes. Multiple lash fusions are initially placed within a case to form a set of artificial lash extensions (step 701). As noted above, the multiple fusions may be positioned in a specific arrangement. For example, the case may include predefined indentations that cause the multiple lash fusions to be arranged in a convex pattern similar to the shape of an eyelid.

0041The individual can then arrange an applicator over the case that includes the set of artificial lash extensions (step 702). The applicator includes opposed arms having concave outer portions that substantially complement the convex pattern of lash fusions included in the set, as well as the convex outer surface of the case. The individual can then apply pressure to the opposed arms of the applicator to securely grasp the multiple lash fusions (step 703). Application of such pressure causes the outer portions of the opposed arms to engage one another and grasp each lash fusion included in the set.

0042The individual arranges the multiple lash fusions proximate to the tightline (step 704), and then attaches the multiple lash fusions to the natural lashes (step 705) by pressing the multiple lash fusions upward against the bottom of the natural eyelashes. Thus, the set of lash fusions may become substantially flush with the lash line. The initial application process can then be completed by discontinuing the pressure applied to the opposed arms of the applicator (step 706). In some embodiments, the individual may further secure the multiple lash fusions to the natural lashes by once again applying pressure to the opposed arms of the application (step 707), which causes the outer portions of the opposed arms to clamp down on the multiple lash fusions and the natural lashes.

0043Unless contrary to physical possibility, it is envisioned that the steps described above may be performed in various sequences and combinations. For instance, the case may already include the multiple lash fusions before corning into the possession of the individual (thus rendering step 701 unnecessary in some embodiments).

0044Other steps could also be included in some embodiments. For example, an adhesive may be applied to the top of each lash fusion in the set of artificial lash extensions. In other embodiments, ad adhesive is applied to the top of each lash fusion in the set of artificial lash extensions during the manufacturing process. The adhesive could be a waterproof glue or mascara. For example, the adhesive may include an oil-soluble polymer that helps to enhance adhesion and substantivity of the artificial lash extensions to the individual's natural lashes. The adhesive may be a waterproof formulation that allows the set of artificial lash extensions to remain affixed to the individual's natural lashes for longer periods of time.

0045Although latex-based adhesives are generally avoided to avoid irritation of the individual's eyelid (e.g., due to an allergic reaction), adhesives can include various other natural ingredients (e.g., sugar or honey) and/or chemical ingredients. For example, copolymer is often a main ingredient in many adhesive formulations. The adhesive could be a commercially-available adhesive for conventional lash extensions or a specialized composition for use with the set of lash extensions described herein. The adhesive could be clear or colored (e.g., milky white or black to emulate mascara).

0046<figref idref="f0013"><b>FIG. 8</b></figref> depicts a flow diagram for a process 800 for manufacturing applicators for applying artificial lash extensions. A pair of metal fragments are initially acquired that are to be formed into an applicator for applying artificial lash extensions (step 801). Generally, the metal fragments is comprised of a metal for improved durability, cleanability, etc. Examples of metals include titanium, hardened steel, stainless steel, etc.

0047Other materials may also be used to form the applicator. For example, the pair of fragments may be comprised of plastic, glass, foam, etc. Moreover, the applicator may be formed from a single piece of material rather than a pair of separate fragments. In such embodiments, the single piece of material can be formed into a v-shaped body having opposed arms and an apex (e.g., through the application of heat to a central point at which the single piece of material is folded).

0048Each metal fragment can be logically divided into an inner portion designed to be gripped by an individual and an outer portion designed to grasp a set of artificial lash extensions (step 802). For example, the outer portion of each metal fragment may be wide enough to simultaneously grasp 4-8 clusters of artificial lashes. In some embodiments, the metal fragments may be slightly thinner at the proximal end (also referred to as the "gripping end") in order to provide greater flexibility.

0049The outer portion of each metal fragment is then formed into a concave shape that may substantially match the tightline curvature of an eyelid (step 803). Said another way, the outer portion of each metal fragment may be contoured to match the curvature of the tightline of an eyelid. This can be accomplished, for example, using appropriately shaped die blocks and machine molding. Such a design enables an individual to simultaneously grasp and apply multiple lash fusions without requiring assistance from another individual (e.g., a medical professional or cosmetician).

0050In some embodiments, a middle portion of each metal fragment is also formed into a concave shape that allows the applicator to rest on the cheek bone, nose bridge, etc. For example, if an individual is holding the applicator in their right hand, then the individual can readily apply a set of artificial lash extensions to the right eye. However, when the individual attempts to apply a set of artificial lash extensions to the left eye, the individual may to balance the middle portion on the bridge of the nose for stabilization.

0051The pair of metal fragments can then be fixedly secured to one another at the proximal end to form opposed arms having an apex (step 804). For example, an individual may use an induction welder to fuse the pair of metal fragments together at the proximal end. This arrangement of the opposed arms allows an individual to securely grasp lash fusion(s) by applying pressure to the opposed arms. Forming the applicator in such a manner also ensures that the opposed arms naturally revert or "spring" back to their original position when pressure is no longer being applied by the individual.

0052In some embodiments, the applicator is treated (e.g., by being powder coated) to improve durability, resistance to scratching, cleanability, resistance to chemicals/solutions, etc. For example, the outer portion of each metal fragment may have a non-stick to avoid stickiness. Examples of non-stick coatings include polytetrafluoroethylene (PTFE) coatings, silicone coatings, etc. Upon being completed, the applicator can be used by an individual to simultaneously grasp and apply a set of artificial lash extensions by applying pressure to the opposed arms.

The method of clause I, further comprising: arranging the applicator over a case that includes the set of lash extensions, <ul id="ul0006" list-style="none" compact="compact"><li>wherein the case includes multiple predefined indentations for receiving a lash fusion, and</li><li>wherein the case includes a convex outer surface on which the multiple lash fusions are arranged, the convex outer surface substantially complementing the crescent shape of the outer portions of the opposed arms.</li></ul></li><li>O. The method of clause I, further comprising: applying an adhesive to a top side of each lash fusion that allows the set of lash extensions to be applied to an underside of the natural lashes of the subject without requiring manual application of an adhesive to the natural lashes.</li><li>P. A method of manufacturing an applicator for attaching artificial lash extensions, the method comprising: <ul id="ul0007" list-style="none" compact="compact"><li>providing a pair of metal fragments that are to be formed into an applicator for attaching artificial lash extensions to the natural lashes of a subject;</li><li>dividing each metal fragment into <ul id="ul0008" list-style="none" compact="compact"><li>an inner portion designed to be gripped by a user, and</li><li>an outer portion designed to grasp lash extensions;</li></ul></li><li>forming the outer portion of each metal fragment into a concave shape able to become substantially flush with a convex shape of a tightline of an eyelid; and</li><li>fixedly securing the pair of metal fragments to one another at a proximal end to form opposed arms having an apex.</li></ul></li><li>Q. The method of clause P, wherein the concave shape of the outer portion of each metal fragment enables multiple lash fusions to be simultaneously affixed to the natural lashes of the subject.</li><li>R. The method of clause Q, further comprising, for each lash fusion of the multiple lash fusions, <ul id="ul0009" list-style="none" compact="compact"><li>forming multiple clusters of artificial lashes;</li><li>connecting the multiple clusters to one another to form the lash fusion; and applying an adhesive to a top side of the lash fusion that allows the lash fusion to be applied to an underside of the natural lashes of the subject without requiring manual application of an adhesive to the natural lashes.</li></ul></li><li>S. The method of clause P, further comprising: applying a non-stick coating to the outer portions of the each metal fragment for the purpose of preventing stickiness.</li><li>T. The method of clause S, wherein the non-stick coating is a polytetrafluoroethylene (PTFE) coating or a silicone coating.</li></ol>
