Description

Decorative eye cover

Technical Field

The present invention relates to a fabric product, particularly but not exclusively, to an eye patch which is decorative to meet the aesthetic requirements of the user. The eye mask may also contain active ingredients to improve the skin condition of the user. The utility model discloses still relate to a sleep tool package, it is the eye-shade that uses when including the sleep.

Priority

The utility model discloses require the priority of china appearance design application 202130539215.1 (application date 2021 year 8 month 18 day) and hong Kong appearance design application 2118520.8 (application date 2021 year 8 month 18 day).

Background

Eye masks are a common fabric product used primarily to block light and/or protect the eyes of a user. The eye mask plays an important role in assisting in eliminating fatigue and sleeping in life or travel. As the standard of living increases, users are required to provide decorativeness in addition to pursuing functionality of the eyeshade. Indeed, eye masks have become a fashion item in certain consumer groups. In order to achieve the decorative effect of the eye mask, most of the eye masks on the market focus on the fabric pattern and/or material of the eye mask. For example, certain eye masks may be provided with a particular design and color, or a particular gloss. However, eye masks with ornamentation (rather than decorative designs) still appear to be under development.

In addition, other additional functions have yet to be developed in addition to the basic functionality of the eye shield to block light and protect the eyes. In this regard, eye masks that provide skin care properties have also been breached in the market place.

External skin care products are typically liquid, gel or lotion ingredients that can be used with paper facial films or pads to hold the ingredients on the skin surface. The mask is a typical example of a combination of a liquid component and a paper mask. Often, the mask is not left on the skin surface for too long a time as the liquid components will evaporate and/or be absorbed by the skin causing the mask to become dry. The mask may in turn dry the skin and cause skin irritation. That is, one mask cannot be used for more than 1 hour or overnight. Also, some people may find the texture of the liquid and mask mixture poor. The liquid composition on the mask is often in excess and thus may leak out of the mask, causing mess or inconvenience. Leakage of the liquid component also results in waste of the active component.

In some cases, gel-type skin care products can be used to keep the skin moist overnight without the use of solid substrates. However, if the user turns and turns while sleeping, they may get stuck and are difficult to pick up and arrange. In this case, most of the ingredients are lost due to the movement of the head.

Accordingly, there remains a need for an improved eye shield that can provide the desired decorative qualities for a particular consumer group, making it a fashion item. In addition, the eye mask can be used for a long time to provide a skin care function and allows a user to conveniently use the eye mask at rest.

SUMMERY OF THE UTILITY MODEL

In light of the foregoing, it is an object of the present invention to provide an eye patch in which the aforementioned disadvantages are eliminated or at least to provide a useful alternative for the trade and the public.

marking the points so that they can be found again later;

-counting the number of intact microcapsules in three spots displayed in the microscope field before washing;

-counting the number of intact microcapsules in said three spots after washing; and

-calculating the proportion of intact microcapsules remaining on the skin care layer relative to intact microcapsules present before the first wash cycle;

it will be appreciated that the magnification may be adjusted for better viewing of the microcapsules and for statistical convenience.

Alternatively, an odor tracker may also be applied to the microcapsules so that the user can simply smell and determine whether or not the microcapsules are still present on the skin care layer after washing. The use of an odour tracker provides a simple and straightforward method for determining the presence of microcapsules.

"skin care" as used herein means regulating and/or improving the condition of the skin. The eye shield provided by the present invention can provide a skin care function, i.e., can be used to adjust and/or improve the skin condition of a user, particularly when the skin care layer is in contact with the facial skin of the user for a certain period of time. The eye mask is dry in use and allows the user to contact it for an extended period of time, for example but not exclusively for at least 30 minutes, or at least 1 hour, without causing damage to the skin. In one embodiment, the user wears the eyeshade of the present invention at rest or during sleep. It is highly advantageous that no excess pulp leaks out of the eye shield and does not feel wet and unwieldy to the user. The active ingredient contained in the microcapsules can be easily absorbed by the skin when the microcapsules are broken.

Thus, in embodiments herein, the eye shield with skin care properties of the present invention refers to products that comprise or are made of fibers and can be used to adjust and/or improve the skin condition of a user. The facing substrate, skin care layer and/or bowtie used in the present application comprise natural fibers, synthetic fibers or a combination of both. In embodiments herein, the fabric substrate may be made of natural fibers (e.g., silk) to provide suitable comfort to the user. In another embodiment, the facestock substrate may be made from synthetic fibers or a combination of natural and synthetic fibers.

In another specific embodiment, the bow may further comprise an ornament selected from the group consisting of glitter, rhinestones, ribbons, and combinations thereof.

In a particular embodiment, the bowknot is removable from the fabric substrate independently of the skin care layer. Thus, the bowknot can be removed separately when the user only needs to use the skin care function of the eye patch of the present invention (e.g., during sleep).

Skin care layer as used herein refers to a layer comprising microcapsules disposed on a fabric substrate. In embodiments herein, the skin care layer may be formed, for example, by: spreading, coating, or piping on the fabric substrate or having the microcapsules contained in the fabric substrate. In another embodiment, the skin care layer can be a separate facestock layer having a thickness to be physically attached directly or indirectly to the facestock substrate. In a particular embodiment, the microcapsules are attached to the fabric substrate by use of an adhesive to form a skin care layer directly on the fabric substrate. The binder is a substrate capable of holding the microcapsules on the facing substrate. The binder used herein may be, for example but not exclusively, acrylic, polyurethane, silicone or a combination thereof.

In another embodiment, the skin care layer is prepared by: by immersing the fabric substrate having a certain thickness into a bath comprising microcapsules and a binder, a separate skin care layer impregnated with microcapsules is then formed and can be removably attached to the fabric substrate to be used.

The microcapsules of the present application encapsulate at least two active ingredients therein for improving skin conditions. Without being limited by theory, it is believed that the use of microcapsules may effectively protect the active ingredients from or minimize effects caused by undesirable external factors, such as excessive humidity, evaporation, heat, oxidation, ultraviolet light, sunlight, and the like. Thus, the shelf life of the skin care product can be extended compared to existing skin care products in liquid or cream form.

In one embodiment, the magnetic attachment system comprises two sets of magnetic elements, one set of magnetic elements disposed on the facestock substrate and the other set of magnetic elements disposed on a bow-tie that is removably attached to the facestock substrate by the attraction between the two sets of magnetic elements. In one embodiment, each set of magnetic elements comprises two magnetic sheets symmetrically disposed on the facestock substrate and the bowknot. Each magnetic sheet may be circular or may have other shapes. Preferably, the size and thickness of each magnetic sheet should not affect the comfort of the eye shield.

Fig. 1 shows an embodiment of the eyeshade of the present invention. The eye mask has a bowknot decoration, the bowknot is located on the fabric substrate covering the eyes of the user.

Fig. 2 further shows a top view of the eye shield of the embodiment shown in fig. 1. The eye mask has a fabric substrate 1, a bow tie 2, a magnetic attachment system 3 for detachably attaching the bow tie 2 to the fabric substrate 1, a skin care layer 4, and elastic strips 5. Wherein the elastic strap 5 is adjustable and integrated into the eye mask by a strap adjustment mechanism (not shown in fig. 2). In this embodiment, the skin care layer 4 is removably attached to the facing substrate 1 by another magnetic attachment system (not shown in FIG. 2). In this embodiment, the magnetic attachment system for attaching the bow 2 may comprise a magnet on the bow 2 and a magnet on the fabric substrate 1, both magnets being magnetically attracted to each other to enable detachable attachment between the bow 2 and the fabric substrate 1. A similar design can be used for the magnetic attachment system for attaching the skin care layer 4. It will be appreciated by those skilled in the art that magnetic attachment systems employing the same or similar mechanisms as the present embodiment are also within the scope of the present invention. The skin care layer 4 may comprise microcapsules which controllably release the skin care active ingredient slowly.

It will be appreciated by those skilled in the art that the skin care layer 4 is optional. The eye patch of the utility model comprises an implementation mode without a skin care layer. In this case, the face fabric substrate is in direct contact with the eyes of the user.

Fig. 3 shows a rear view of the eyecup of the embodiment shown in fig. 1. The fabric substrate can be seen to have a shape conforming to the eyes of a user and an area covering the eyes and the periphery of the eyes. When provided with a skin care layer, the skin care layer may have a similar shape and a similar or slightly smaller footprint to controllably delay the release of the active ingredient to the eye and periocular locations of the user. The elastic strips are attached to the two ends of the face stock and have a length at least as long as or slightly longer than the face stock in an unstretched condition. In the use state, the elastic band is stretched and placed in the back position of the user's brain, and its elasticity fixes the eye mask in the eye position of the user. The length of the elastic strip can be adjusted, so that a user can control the contact tightness between the fabric substrate and/or the skin care layer and the eye position and the wearing comfort of the eye mask. Preferably, the material of the textile substrate, the skin care layer, the elastic strips and/or the bows may be selected from natural fibres, such as natural silk, to increase the comfort of the user.

Fig. 4 shows a schematic view of the construction of the eyecup of the embodiment shown in fig. 1. Wherein the decorative bow and the fabric substrate are in a separated state. The bowtie may be conveniently attached to or removed from the facestock substrate by a magnetic attachment system.

Fig. 5 to 6 show an eye mask 100 according to another embodiment of the present invention. The eye mask 100 is wash-durable and skin-protective and decorative. The eye mask 100 includes a fabric substrate 102 having elastic bands 104. The face fabric substrate 102 comprises natural fibers, and in this particular embodiment, the face fabric substrate 102 consists essentially of silk, which provides sufficient flexibility and comfort to the user. The elastic strips 104 may be wrapped with silk or other fabric. The eye patch 100 further includes a separate skin care layer 106 removably attached on the back side of the facestock substrate 102 such that the skin care layer 106 faces the user when in use.

The skin care layer 106 is impregnated with microcapsules (see 400 in fig. 7A) that include at least an active ingredient. The microcapsules may release the active substance to the user upon actuation, e.g., by mechanical pressure or biodegradation. The microcapsules in this embodiment can release the active ingredient in a controlled manner for an extended period of time and are readily subjected to mechanical pressure applied by the user. In other words, the microcapsules can rupture to release the active ingredient in a slow release manner to continuously deliver the active ingredient to the user's skin while the user sleeps wearing the eye mask 100. At the same time, the user will not feel a wet feel or feel that the applied skin care active is dirty.

Fig. 7A shows the microcapsules 400 intact, bonded to the fibers 402, prior to rupture, while fig. 7B shows the microcapsules 500 ruptured to release the active ingredient after being subjected to mechanical stress or biodegradation. As shown in fig. 7B, ruptured microcapsules are found on the fibers 502, despite the release of the active ingredient therefrom.

In this embodiment, the microcapsules have an average diameter of: from about 1 μm to about 25 μm; or from about 2 μm to about 15 μm; or from about 3 μm to about 10 μm; or from about 5 μm to about 8 μm; or about 5 μm. Preferably, the microcapsules have a narrow size distribution prior to, for example, attachment to a fabric substrate, skin care layer, or the like.

The skin care layer 106 may be woven to the facestock substrate 102 or attached to the facestock substrate by an adhesive mechanism. In fig. 5 and 6, the skin care layer 106 can be removably attached to the facestock substrate 102 by this adhesive mechanism, which is represented by two straps 108 disposed on the skin care layer. The strap 108 may then be attached to the face stock 102. The adhesive mechanism provides a user-friendly method for the user to remove the removable skin care layer from the eye shield when desired. For example, the following cases: when the microcapsules on the skin care layer are used up and a new skin care layer needs to be replaced with unbroken microcapsules; when the eye mask is washed but the user does not want to wash the skin care layer; or in other scenarios, the adhesion mechanism may be useful.

In this embodiment, the skin care layer 106 can be removed from the fabric substrate 102 and a new piece of skin care layer can be attached thereto. Alternatively, the removable skin care layer 106 may be removed from the facestock substrate 102 prior to washing.

Alternative adhesive mechanisms may include, but are not exclusive of, buttons, zippers, hook and loop fastener systems, magnetic fastener systems, and the like. In one embodiment, the skin care layer is removably attached to the fabric substrate by a magnetic fastener system comprising one or more magnetic elements on the fabric substrate and/or the skin care layer. Those skilled in the art will understand how to arrange the adhesive means to physically hold the skin care layer directly or indirectly to the facing substrate. Other possible bonding mechanisms may also be employed in the present invention to achieve the effects disclosed herein.

In alternative embodiments, the skin care layer may be woven or otherwise permanently attached to the fabric substrate, forming a one-piece eye cover.

Alternatively, the elastic strap 104 may be made adjustable by integrating a strap adjustment mechanism into the eye mask 100. For example, the elastic strap 104 may have one end woven into the facestock substrate 102 and the other end removably attached to the facestock substrate 102 via strap adjustment mechanisms 110, 112. The strap adjustment mechanism includes a plurality of holes 112 on the removable end of the elastic strap 104 and a button 110 disposed on the facestock substrate 102 that fits into the holes on the elastic strap according to the desired length of the user. Thus providing the user with a user-friendly eye mask to adjust as desired under different conditions (e.g., at home or while traveling).

The utility model also comprises a method for preparing the eye mask with skin care performance. In particular, the method comprises preparing microcapsules comprising an active ingredient; the microcapsules are disposed on or on the facing substrate to form a skin care layer, and optionally the skin care layer is attached to the facing substrate.

In embodiments herein, useful microcapsules are prepared by in situ polymerization having the following steps:

i) Preparing a mixture comprising polymer precursors by dissolving a first monomer and a second monomer in an aqueous solution having a pH of about 7 to 10, and optionally heating the mixture at a temperature above 50 ℃;

ii) adding the mixture of polymer precursors to the mixture comprising the active ingredient;

iii) Adding a surfactant to the mixture in step ii) and stirring thoroughly;

iv) activating the polymer precursor in the mixture in iii) to undergo polymerization;

v) optionally adding a scavenger to remove excess reactant from the resulting mixture;

vi) filtering the microcapsules and optionally washing the microcapsules to remove impurities.

As used herein, "polymer precursor" (also referred to as prepolymer) refers to a monomer that has been activated to an intermediate molecular mass state and can undergo another polymerization to form a fully cured polymer having a high molecular mass state. In one embodiment of the present invention, the aminopolymer precursor is prepared by dissolving a first monomer and a second monomer in an aqueous solution. The pH of the aqueous solution is increased to promote the formation of an intermediate molecular mass state.

In step (iv), after the active ingredients are mixed, the pH of the compound is adjusted to less than 7, thereby promoting polymerization in an intermediate molecular mass state to form a polymer having a high molecular mass state. The low pH also improves the formation of microcapsules with smaller particle size. Without being bound by theory, it is believed that the low pH reduces the surface tension of the continuous phase resulting in improved emulsification between the monomers and thus microcapsules formed can have a narrow size distribution and a smaller average diameter.

A scavenger may be added to remove excess reactant (e.g., monomer) to form the resultant mixture in step (v). In one embodiment, formaldehyde is used as the first monomer and melamine is used as the second monomer to form the melamine resin. A formaldehyde scavenger may be used in step (v) to remove excess unreacted formaldehyde. The formaldehyde scavenger may be a primary, secondary or tertiary amine, ammonia, glycine, urea, ethyleneurea, ethylacetoacetate or sodium bisulfite acetoacetamide. Alcohols such as methanol and ethanol may also be used to remove other excess unreacted reactants.

Subsequently, for example, coating, filling, and spraying processes can be applied to attach the microcapsules to the fabric substance/layer or on the fabric substrate to form the skin care layer. In one embodiment, referring to fig. 8, microcapsules are disposed in a liquid bath 600 that includes a binder. The binder may be acrylic, polyurethane, silicone, or the like to bind or secure the microcapsules to the facestock layer or facestock substrate 602. The adhesive is capable of retaining at least about 50% to about 100%, or about 60% to about 100%, or about 75% to about 100%, or about 90% to about 100% of the microcapsules on the skin care layer during the wash cycle. A layer or substrate of fabric 602 is then placed in the liquid bath 600 by the impregnation unit 604 to occupy the microcapsules. After this, the facestock or facestock substrate 602 is subjected to a filling process and/or a curing process by a calender 606 and/or a tenter 608 to cure and attach the microcapsules to the facestock or facestock substrate 602. Those skilled in the art will appreciate that the machines typically used in the textile industry are suitable for use in the present invention to obtain a skin care layer with microcapsules. For example, a tenter frame as used herein is a common machine commonly used for stretching and heat setting fibers. Alternatively, a washing step and a drying step may be performed to remove excess reactants.

The utility model also relates to a method for smearing the washable skin-care eyeshade. The method comprises the following steps:

-placing a wash-resistant skin care eye shield on the user, wherein the skin care layer is to be placed in direct contact with the user's skin for at least about 15 minutes; or from about 15 minutes to about 22 hours; or from about 30 minutes to about 20 hours; or from about 1 hour to about 16 hours; or from about 2 hours to about 12 hours; or from about 3 hours to about 11 hours; or from about 4 hours to about 10 hours; or from about 15 minutes to about 3 hours; or from about 25 minutes to about 2 hours; or from about 30 minutes to about 1.5 hours;

-washing the eye patch and/or skin care layer for at least one washing cycle when the eye patch and/or skin care layer has dust or contaminants thereon, wherein at least about 50%; or 50% to 100%; or 60% to 100%; or 75% to 100%; or from 90% to 100% of the microcapsules remain on the skin care layer after the wash cycle relative to the amount of microcapsules present prior to the wash cycle; and

-removing the decorative bow from the textile substrate when the decorative properties of the washable skin care eye shield are not required or when washing is required.

As described above, the wash-durable skin care patch can withstand at least 5 wash cycles, at least 10 wash cycles, at least 15 wash cycles, at least 20 wash cycles, at least 25 wash cycles, or at least 30 wash cycles, and after a wash cycle, at least about 50%, about 60%, about 70%, about 80%, or about 90% to about 100% of the microcapsules remain intact on the skin care layer relative to the amount of microcapsules present prior to the first wash cycle. Specifically, after 5 wash cycles, about 75% to about 100% of the microcapsules may remain intact on the skin care layer, after 10 wash cycles about 50% to about 85% may remain intact on the skin care layer, after 15 wash cycles about 35% to about 70% may remain intact on the skin care layer, after 20 wash cycles about 15% to about 50% may remain intact on the skin care layer, or after 30 wash cycles about 3% to about 30% may remain intact on the skin care layer, relative to the microcapsules present before the first wash cycle.

In one embodiment of the present invention, the wash-resistant skin care mask is placed on the user in a dry state without the use of any adhesive in liquid or cream form. In other words, no excess liquid or cream seeps out of the skin care layer.

Fig. 11 shows another embodiment of the present invention. In this embodiment, the washable skin care eye shield has a decorative bow that is removably attached to the eye shield body (primarily the fabric substrate 1) by a magnetic attachment system. The bowknot is decorated with a plurality of pearl-shaped ornaments with different sizes. It will be understood by those skilled in the art that the size, color, material and number of the pearl-like decorations can be determined by those skilled in the art according to the aesthetic, cost and/or practical requirements. The specific decoration manner of the present embodiment should not be considered as narrowing the protection scope of the present invention.

Specifically, part (a) of fig. 11 shows a top view of a decorative bow of the wash-resistant skin care eye shield when attached to the eye shield body. The decorative bow is seen attached to the eyecup body in a manner that is co-axial with the eyecup body. Part (B) of fig. 11 shows a top view of the wash durable skin care eye shield with the decorative butterfly partially removed from the eye shield body. Portion (C) of fig. 11 then shows a top view of the washable skin care eyeshade with the decorative bow completely removed from the eyeshade body. As can be seen from portions (a) to (C) of fig. 11, the decorative bow can be easily and conveniently attached to and removed from the eyecup body.

Fig. 12 is a rear view of the embodiment shown in fig. 11. Part (a) of fig. 12 shows a back view of the decorative bow of the wash-resistant skin care eye shield when attached to the eye shield body. Part (B) of fig. 12 shows a back view of the wash and skin resistant eyeshade when the decorative bow is removed from the eyeshade body. It can be seen that the attachment or removal of the decorative bow does not cause any structural change to the portion of the back side of the eyecup that contacts the user's eyes and periocular skin. Therefore, the eyeshade of the present invention can be comfortably used in either a state where the bow is attached or removed.

Fig. 13 illustrates the principle of action of attaching and removing the decorative bow tie by means of the magnetic attachment system in the embodiment shown in fig. 11. In this embodiment, two sets of magnetic elements are placed in the eyecup body and the decorative bow, respectively, and the two sets of magnetic elements attract each other magnetically (indicated by dotted dashed lines in fig. 13). In this embodiment, each set of magnetic elements comprises two substantially circular magnetic sheets, respectively. The magnetic sheets of each set are arranged symmetrically along the X-axis in fig. 13 on the eyecup body and the bow, respectively. It will be appreciated by those skilled in the art that the shape, number and arrangement of the magnetic sheets in the eyecup body and decorative bow may be varied and/or adjusted according to particular needs.

As shown in fig. 13, when it is desired to attach a decorative bow tie to the eyeshade body, the bow tie is progressively closer to the eyeshade body until the magnetic interaction between the eyeshade body and the magnetic elements in the bow tie attracts the bow tie to the eyeshade body. Due to the nature of the magnetic attachment, the attachment position of the bow to the eyecup body can be adjusted slightly as the magnetic action allows. When it is desired to remove the decorative bow from the eyeshade body, the user may apply a force to the bow in a direction away from the eyeshade body, and when the applied force is greater than the magnetic interaction between the bow and the eyeshade body, the decorative bow is removed from the eyeshade body. By this magnetic attachment system, the decorative bow of the present embodiment may be easily and conveniently attached to and/or removed from the eyecup body.

It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments described above without departing from the spirit or scope of the invention as described above. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.

Example 2

Preparation of microcapsules

The microcapsule is prepared by adopting an interfacial polymerization method. The hydrogen formaldehyde, melamine and water are thoroughly mixed to form an aqueous solution (A). To ensure complete dissolution, the pH of solution A was adjusted to 8.5-9.0 and the temperature was adjusted to 70-80 ℃.

The active ingredient and emulsifier as described in the formulation of example 1 were mixed in the organic solvent dichloromethane to form organic solution (B). Solution B was mixed with solution (A) in a homogenizer at a speed of 3000 to 4000 rpm. During mixing, water is gradually added to the mixture to trigger microencapsulation of the two phase interfaces (i.e., between the organic and aqueous phases). Methanol and formaldehyde scavenger are added to the resulting mixture to remove any excess unreacted formaldehyde.

Example 3

Filling process

The microcapsules obtained in example 1 were introduced into the bath. The concentration of microcapsules in the bath is about 70-90g/l. The bath also included 50g/l binder, 20g/l softener and 2g/l wetting agent. The fabric was immersed in the bath and passed into a padding/extrusion cylinder. The minimum uptake rate (pick-up ratio) of the bath was 80-90%. Then the microcapsules are evenly distributed on the fabric to form a skin care layer. The absorption rate (%) of the bath lotion is the percentage of the mass of the bath lotion absorbed by the woven fabric to the mass of the dry fabric, and is calculated according to the following formula:

absorption rate = (mass of fabric after bath) - (mass of dry fabric)/(mass of dry fabric)

Mass in g/m ² And (6) metering. Thus, the mass of microcapsules imbibed by the fabric can be calculated based on the following equation:

mass percent w/w of microcapsules on the fabric = mass kg of dry fabric x uptake (%) × concentration of microcapsules in the bath.

In this example, the mass percent of microcapsules per 1 square meter of fabric (w/w) was calculated by 1kg dry fabric x 85% x 70/1000=5.95 w/w when the concentration of microcapsules in the bath was 70g/l and the uptake rate was 85%.

Finally, in this example, the web was passed through a tenter frame. The microcapsules were fixed on the fabric by a heat fixing process at about 160 ℃ and the speed of the dryer was set to 10m/min to provide a drying time of about 3 minutes at about 160 ℃. The result is a skin care layer containing microcapsules.

Example 4

Manufacturing eye cover

In example 3, the skin care layer impregnated with microcapsules was woven and cut into a mask. The hook component of the hook-and-loop fastener is disposed on one side of the skin care layer. A fabric substrate made of silk with cotton embedded therein was prepared in the form of an eye mask (similar to a skin care layer), and the fabric substrate had linear fastening strips on its surface, which were coupled with hook members on the skin care layer. The skin care layer is then attached to the face stock via hook and loop fasteners to form the eye mask of the present invention.

In addition, the eye mask is also connected with an elastic strip. The user can easily wear the eye mask by means of the elastic straps while the elastic straps firmly secure the mask to the user's eyes. Microcapsules applied to the skin care layer in contact with the user's skin may rupture to release the active ingredient while the user sleeps. Fig. 9 and 10 show examples of the eye patch of the present invention with or without ornaments, respectively.
