CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 11/191,372, filed Jul. 26, 2005, the contents of which are herein incorporated in their entirety.
FIELD OF THE INVENTION
The present invention relates to the application of self-tanning agents to the skin, and more particularly to a novel kit having an improved applicator glove which protects the palms of the hands and ensures even coverage.
BACKGROUND OF THE INVENTION
Tanned skin is viewed as healthy and vital, and the acquisition of a tan is seen by many as a part of an essential beauty regimen to achieve an attractive appearance. However, medical science has demonstrated the dangers of exposure to the sun, particularly UVA and UVB radiation exposure. A spike in the frequency of skin cancers (such as basal cell carcinoma, squamous cell carcinoma and malignant melanoma) can be directly attributed to society's growing emphasis on sun-worshiping. It is also well established that sun exposure can accelerate the aging process of the skin, causing premature wrinkling, discoloration, and loss of tone.
In order to satisfy the public's desire for a healthy, tanned appearance, topical self-tanning preparations have been developed which give the skin a tanned appearance. The self-tanning preparations work by staining or coloring the skin, thus allowing one to impart a bronze color to human skin without exposing the skin to natural or artificial sunlight. Self-tanners are available in liquid, cream, mouse, or gel form which can be applied with the hands.
Self-tanning compositions usually contain one or more self-tanning agents, the most common of which is dihydroxyacetone ("DHA" 1,3-dihydroxy-2-propanone). DHA works through interactions between its hydroxy groups and the amino groups of amino acids and peptides naturally occurring in the skin. These reactions lead to the formation of brown pigments in the skin, thereby giving it an appearance similar to that of a naturally obtained tan. DHA is usually suspended in a water in oil emulsion.
Early self-tanning products were generally unsatisfactory because they tended to turn the skin an unnatural orange color. The self-tanning products currently commercially available are vastly improved over earlier versions in that they can deliver a natural-looking color that appears to be a genuine suntan. However, even with these improved products, uneven application will result in tell-tale streaks and discolorations. Since the color is designed to last for several days, mistakes in application cannot be readily corrected.
Self-tanning preparations which do not contain oil-color the skin more quickly, however such preparations do not spread evenly on, the skin. A water-based DHA solution is in many ways preferable to an oil-based, however such a solution has such a low viscosity that it often drips and causes streaks in the final result. An effective applicator means for aqueous DHA solutions having sufficient absorption properties to deliver an even application would therefore be highly desirable.
When applying self tanning preparations, it is important to shield the hands from the preparations, since darkened palms and fingers are unnatural and an undesirable result. This need is addressed in the prior art in Gueret, U.S. Pat. No. 6,723,306, which discloses a self-adhering lotion applicator device for adhesive attachment to the hand. The pad is mitten-shaped, and has an adhesive surface and a lotion applicator surface. The Gueret pad is effective for shielding the hand, however in use it would be cumbersome and would greatly limit the wearer's dexterity when applying lotion since the fingers cannot be independently moved.
It is known in the art to utilize plastic or rubber gloves when applying self-tanning compositions, however plastics and the like do not yield optimum results. Since the tanning product is usually unevenly distributed on the surface of the plastic or rubber glove, the application is uneven, and streaks can easily result. Therefore, what is needed is an easy to use application device of a suitably absorbent material which provides coverage quality superior to that provided by a plastic or rubber glove.
The present invention utilizes a novel tanning composition application article comprised of microfiber material. The unique properties of the microfiber material provide a self-tanning composition applicator having absorbent properties which make it superior to all prior art methods.
Microfibers are very fine fibers compared to more conventional textile fibers. For example, microfibers are half the diameter of a silk fiber, one-third the diameter of cotton, one quarter the diameter of fine wood, and one hundred times finer than human hair. Microfibers are finer than any fibers occurring in nature. In order to be called a "microfiber," the fiber must be less than one denier. "Denier" is a weight per unit measure of any linear material defined as the number of unit weights of 0.05 grams per 450-meter length. This is numerically equal to the weight in grams of a 9000-meter length of fiber or yarn. The term defines the diameter or fineness of a continuous or filament fiber such as silk or man-made fibers, with low numbers representing finer sizes and the higher number coarser sizes.
The increasing popularity of self-tanning preparations has created a need for an improved means of applying self-tanning preparations to the skin, and the present invention addresses this need by utilizing microfiber materials in combination with spandex to create a novel one-size-fits-all-applicator glove which has sufficient absorbency for even application of the self-tanning product.

FIG. 2 is a cross-sectional view of the application glove of the invention taken along the line 2-2' in FIG. 1.
DETAILED DESCRIPTION OF THE INVENTION
Although the invention will be described in terms of a specific embodiment, it will be readily apparent to those skilled in this art that various modifications, rearrangements, and substitutions can be made without departing from the spirit of the invention. The scope of the invention is defined by the claims appended hereto.
FIG. 1 illustrates the elements of the inventive kit 10 according to a preferred embodiment. The kit includes a self-tanning composition 12 in a suitable container and an application glove 14. Other elements of the kit 10 can include a cleansing/exfoliant preparation 16 and an emollient preparation 18, both in suitable containers.
The self-tanning composition 12 can be any suitable product which includes a self-tanning agent. The self-tanning agent can be dihydroxyacetone ("DHA") CH2OHC(O)CH2OH. Other suitable self-tanning agents include, without limitation, methyl glyoxal, glycerol aldehyde, erythrulose, alloxan, 2,3-dihydroxysuccindialdehyde, 2,3 dimethoxysuccindialdehyde, 2-amino-3-hydroxysuccindialdehyde, and 2-benzylamino-3-2-amino-3-hydroxysuccindialdehyde. The self-tanning agent is suspended in any suitable pharmacologically acceptable carrier, which can be a water-in-oil emulsion or a water-based substrate. The self-tanning composition 12 can be in foam, gel, mouse or cream form, with the type of container selected to be appropriate to the type of composition.
The application glove 14 of the invention has an outer layer of a flexible, skin-like material which will absorb the product and spread it evenly. In the preferred embodiment, the application glove 14 is constructed from microfiber fabric including microfibers of 1.1 denier or less. In the preferred embodiment, the microfibers are about 1 denier or less than 1 denier. The microfiber can be cellulosic fiber, polyester or other synthetic (petroleum-based) fiber, or cellulosic fiber in combination with synthetic fibers, either in mechanical or intimate blends. The microfiber fabric can be knit or woven. Suitable knitted constructions include, but are not limited to, single knit, double knit, warp knit, rochelle knit, or tricot. As will be discussed in detail hereinafter, the glove includes an inner barrier layer of a flexible impermeable material to protect the hand.
The glove 14 can be manufactured from cellulosic fibers, such as cotton, or synthetic petrochemical fibers, such as polyester. The fibers may be used in 100% form, or from blended fibers, including cellulosic fiber in combination with synthetic fibers, either in mechanical or intimate blends. Spandex (such as Lycra® manufactured by DuPont), monofilament, rubber, or elastomerics may be utilized or introduced to the fabric construct to create a "one size fits all" property. Jersey constructions and interlock knits which are designed to have mechanical stretch in both length and width can be used for greater comfort and fit.
In the preferred embodiment, the glove fabric is a basic single knit jersey including polyester microfiber. The knit microfiber fabric includes a spandex component to provide sufficient elasticity to the fabric to create a one-size-fits-all applicator glove. The spandex component advantageously allows the applicator glove 14 to be constructed to fit snugly on the hand. The microfiber/spandex applicator glove 14 of the invention allows the user greater dexterity and touch sensitivity than prior art plastic gloves.
The fabric for the preferred embodiment of the glove 14 is knit from two dissimilar yarns, the first being a polyester microfiber of about 1 denier or less, and the second a polyester/spandex blend fiber which can be greater than 1 denier. In manufacturing the fabric of the glove of the invention, a knitting process is used to create a knitted fabric having a technical front consisting of mostly of polyester microfibers, and a technical back consisting of mostly polyester spandex fibers. The surface of the technical front therefore primarily includes the polyester microfibers, which forms the contact/application surface of the glove 14. It will be appreciated by those skilled in the art that in the fabric produced in the knitting process the polyester microfibers and the polyester/spandex fibers are not distributed in discrete layers in the fabric. However, in the microfiber fabric of the invention the fibers of one yarn are predominantly located on the technical front of the fabric and the other yarn fibers are predominantly located on the technical back of the fabric.
This dual-sided construction of the knitted fabric provides numerous advantages. Since microfiber is relatively expensive to manufacture, and therefore more costly, it is more economical to combine the microfibers with inexpensive non-microfiber yarns in a construction which concentrates the microfibers on one application side. It is also more advantageous to have an application layer, i.e. the technical front comprising microfibers, which is much more absorbent than the technical back. In this way the self-tanning preparation is maintained primarily on the surface during the application process where it can be applied to the skin and is not absorbed into the glove.
A representative cross-sectional view of the glove 14 is shown in FIG. 2 (greatly enlarged to show detail). The glove 14 is constructed from a microfiber fabric 30 having a technical front and a technical back, with the technical front of the fabric forming the outer surface 31 (or application surface) of the glove 14. As discussed above, the material is preferably knit so that the technical front consists in large part of the microfiber yarn, and the technical consists in large part of a spandex/polyester blend In the preferred embodiment, the glove 14 has two discrete layers, an outer application layer consisting of the microfiber fabric 30 and a second inner barrier layer in the form of liner 34 which prevents the stain from reaching the hands. The liner 34 is positioned in juxtaposed relation to the application layer 34, and can be adhered to the microfiber fabric 30 or otherwise sewn into the seams 36 of the glove so as to be adjacent to the microfiber fabric 30. The liner 34 can be any suitable liquid impermeable material such as natural or synthetic rubber, plastic, PVC, latex or polyester. In the preferred embodiment, the liner 34 is coextensive with the microfiber fabric 30 so that it extends over the entire technical back of the fabric 30. However, for applications where the glove 14 is not fully submersed in a substance, the glove 14 can be constructed so that the liner 34 only shields the palmar section and fingers of the hand in order to provide a more comfortable fit. The liner 34 can be attached to the microfiber fabric using any suitable means, including, but not limited to, stitching, heat sealing with no stitches, laser cutting, adhesives, spray laminating, and heat-sealed stitches.
The glove 14 is described herein as being for the application of self-tanning preparations, however the glove 14 constructed in accordance with the principles of the invention can be used in combination with a variety of products, particularly staining products, for application of the product to a surface. For example, the glove 14 can be used to apply wood stains, automobile polish, silver polish, and furniture oils. The body of the glove 14 can be made in fibers and constructions that are specific to the end use.
A suitable microfiber fabric for the application glove 14 is Ultrasuede®, a nonwoven synthetic suede-like material which is described in U.S. Pat. No. 3,705,226 for "Artificial Leather and a Method for Manufacturing the Same." The content of this patent is hereby incorporated by reference. Ultrasuede® is manufactured by Toray Ultrasuede (America), Inc.
In a knitted construction, first and second yarns of different compositions can be knit together to provide a technical front consisting of the first yarn and a technical back consisting of the second yarn. To provide an application glove 14 which is economical to produce, a first microfiber yarn of less than 1 denier can be knit with an inexpensive second yarn which can be greater than 1 denier (e.g. a polyester) to create a fabric with a technical front consisting of the microfiber yarn. The fabric thus produced can be used to provide an application glove with an application surface consisting of microfiber yarn of less than 1 denier, with the technical back of the fabric consisting of non-microfiber yarn. In the preferred embodiment, the first yarn consists of 75 denier, 75 filament polyester microfiber (1 denier per filament) and 40 denier 4 filament spandex (10 denier per filament), and the second yarn consists of 70 denier 34 filament polyester fibers (about 2 denier per filament). The fabric preferably consists of approximately 45% of 75 denier, 75 filament polyester microfiber, approximately 15% 40 denier 4 filament spandex and approximately 40% 70 denier 34 filament polyester fibers, thus providing a fabric composition of approximately 85% polyester and 15% spandex.
The fabric of the preferred embodiment can be constructed according to the following specification:
1. 11.5-12 oz/linear yard (.+-0.10%)
2. 58-60 inches (.+-0.10%)
3. 70 denier 34 filament@40%, 75 denier, 75 filament polyester micro-fiber@(45%, 40 denier filament Spandex@15% (.+-0.10%)
4. 1 denier per filament microfiber (.+-0.10%)
5. 10 denier 4 filament relaxed (.+-0.10%)
6. 2 bar Tricot
7. 28 cut (.+-0.10%)
The finishing for the fabric can include denier reduction chemicals during the dying and aqueous processing. Surface or face finishing can include caustic reduction, napping, brushing, sueding, and shearing can be used to increase surface filament count to increase surface acceptance of fluids.
An alternative embodiment of the glove 14 for use with water-based or other low-viscosity solutions is made from microfiber fabric having polyester and polyamide fibers in combination, preferably 50% polyester and 50% polyamide. To create a highly absorbent fabric, the microfiber is subjected to a "splitting" process to split the polyester from the polyamide. The split fiber allows the polyamide to pull liquid into the fiber, thereby creating a wicking action through capillary flow. The glove 14 thus formed is ideal for use with aqueous solutions, such as DHA suspended in an oil-free substrate, as well as other low viscosity solutions. The solution is immediately absorbed into the glove 14 so it can be applied to a surface with minimal dripping.
The human epidermis is continually generating new skin cells and shedding older, dead skin cells. When skin is subjected to the self-tanning agents, it can happen that the newer skin cells can absorb the color differently than older cells. To obtain a even coloration and optimal results, it is advantageous to slough off the dead skin just prior to applying the self-tanning preparation 12. The kit 10 of the invention therefore includes a cleansing/exfoliating composition 16 in a suitable container. The cleansing/exfoliating composition 16 can be any suitable commercially available product. To keep the skin moisturized after application of the self-tanning composition 12, the kit 10 can also include an emollient composition 18 in a suitable container. Application of the emollient compositing 18 to the skin helps lengthen the life of the color application by moisturizing the skin to prevent skin flaking.
As shown in FIG. 1, the kit 10 can also include at least one disposable plastic glove 44. The plastic glove 44 can be worn on the hand opposite the application hand in order to remove the sodden glove 14 from the application hand after the self-tanner 12 is applied. In a preferred embodiment, the kit 10 can include a plurality of disposable plastic gloves 44 for multiple applications. The kit 10 can also include a disposable tray 46 for placement of the glove 14 after application to minimize cleanup. The kit 10 can also include a detergent composition 48 for in a suitable container for washing the glove. The detergent composition 48 can be specific to the type of microfiber used.
To use the kit of the invention the apply self-tanning composition 12, the user can first cleanse the skin with the cleansing/exfoliating composition 16. The microfiber application glove is then donned on the application hand, and is used to apply the self-tanning preparation 12. The glove 14 can be removed using a plastic glove 44 worn on the opposite hand, and placed in the tray 45 to minimize cleanup. The emollient composition 18 can be applied after application. The glove 14 is re-usable, and can be machine laundered or hand-washed for future applications.
It is to be understood that while a certain form of the invention is illustrated, it is not to be limited to the specific form or arrangement of parts herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown and described in the specification and drawings
