Description

CROSS-REFERENCE TO RELATED APPLICATIONS
• This application claims priority to U.S. Provisional patent application No. 60/470,218, filed on May 14, 2003, the contents of which are hereby incorporated by reference in their entirety.[0001]
BACKGROUND OF THE INVENTION
• 1. Field of the Invention[0002]
• The invention relates to absorbent shields for use between skin and clothing and, more particularly, to under arm/breast perspiration shields.[0003]
• 2. Description of Related Art[0004]
• The under arm and chest areas of the body are both provided with ample sweat glands and typically perspire readily, even during periods of normal, non-strenuous activity. Although both genders perspire in the under arm and chest areas, the problem of under arm/breast perspiration may be particularly acute for women, whose bras and other undergarments may increase heat retention and, thus, increase perspiration.[0005]
• Perspiration may cause a woman embarrassment in social settings, because it soaks into clothing and may be readily apparent, particularly in the case of clothing made with sheer and thin fabrics. While both men and women typically wear under arm deodorant compositions, these compositions can cause fabric damage, staining, and lingering odors, and are not typically used over the entire under arm/breast area.[0006]
• Various types of products for perspiration control have been proposed and used with varying degrees of success. One type of product is a reusable or disposable perspiration pad that is either sewn or pinned underneath the sleeve of outer garments. These pads are somewhat inconvenient and may function better for men than women, because women's fashions often include sleeves that are oversized for comfort; therefore, perspiration stains are more likely at the sides of the sleeve than on the underside. However, these pads typically do not have enough area to cover the sides of the sleeve. Moreover, many women's garments are constructed of sheer or lightweight fabrics that would be damaged by pad attachment, or are insufficient to conceal the pad.[0007]
• Reusable pads that are positioned beneath the armpit and are fixed to bra or tank top straps by loop fasteners have also been developed. These pads address some of the issues noted above, but the attachment design may be somewhat awkward for the wearer, since the fasteners typically position the pads directly underneath the armpit. Additionally, they too may be difficult to conceal.[0008]
• A woman seeking to reduce the appearance of perspiration on outergarments could simply wear another undergarment, such as an undershirt or a camisole. However, these undergarments may actually increase perspiration, particularly on warm days. Moreover, because of the variety of patterns in outergarment necklines, the outergarment may not conceal the camisole or undershirt. Additionally, everyday wear of undergarments may be expensive.[0009]
SUMMARY OF THE INVENTION
• One aspect of the invention relates to a perspiration shield. The perspiration shield comprises an absorbent portion that is shaped and adapted to be coupled to a side strap of a bra. The absorbent portion has inward and outward faces and includes an under arm portion and a breast portion. The under arm portion is shaped and arranged to extend from the side strap to cover at least a portion of a user's under arm area. The breast portion is contiguous with the under arm portion and is shaped and arranged to cover at least a portion of the user's breast area. At least one of the inward and outward faces is at least partially comprised of an absorbent material adapted to absorb perspiration from the user's under arm and breast areas.[0010]
• Another aspect of the invention relates to a perspiration shield. The perspiration shield comprises an absorbent portion shaped and adapted to absorb perspiration from at least the under arm area of a user. The perspiration shield also comprises an attachment portion contiguous with the absorbent portion, the attachment portion being shaped and adapted to attach the perspiration shield to a side strap of a bra by folding over the side strap.[0011]
• A further aspect of the invention relates to a perspiration shield. The perspiration shield comprises an absorbent portion shaped and adapted to absorb perspiration from at least the under arm area of a user. An attachment portion is contiguous with the absorbent portion. The attachment portion is dimensioned, shaped, and adapted to removably attach the perspiration shield to a cup of the bra. Fabric adhesive is provided and positioned on the attachment portion so as to adhere to the cup of the bra.[0012]

DETAILED DESCRIPTION
• In general, embodiments of the invention provide perspiration shields that attach to the bra of a user and shield at least a portion of the under arm area and, in some embodiments, at least a portion of the breast area. Perspiration shields according to the invention may be lightweight and disposable.[0024]
• FIG. 1 is a perspective view of a perspiration shield, generally indicated at[0025]10, according to an embodiment of the invention, as installed on thebra12 of a user U. Theperspiration shield10 generally comprises anabsorbent portion14, which is sized, shaped, and adapted to cover at least a portion of the under arm area and at least a portion of the breast area, and anattachment portion16, which is adapted to attach to theside strap24 of thebra12 by folding over theside strap24.
• The[0026]perspiration shield10 would generally have a thickness conducive to easy concealment under an outergarment, for example, a thickness of no more than a few millimeters. Typically, theperspiration shield10 would be constructed of lightweight materials and, particularly, lightweight, low-cost materials that lend themselves to disposability. These features of the invention will be described below in more detail.
• The[0027]absorbent portion14 of FIG. 1 is installed on thebra12 such that the widest portion of theabsorbent portion14 covers a portion of the breast area. As used herein, the term “breast portion” may describe any portion of theabsorbent portion14 orperspiration shield10 that is constructed and arranged to fit under, around, or to the side of the breast and, more generally, may also describe any portion of theperspiration shield10 that extends into thecup20 of thebra12.
• Generally, the[0028]absorbent portion14 is shaped such that a portion extends upwardly from theside strap24 and terminates in the under arm region with an outwardlycurved edge25. Theabsorbent portion14 widens toward its lower front, near the front of thebra12, and terminates in an outwardlycurved edge27. Theabsorbent portion14 may be constructed of any material of suitable absorbent properties and, in some embodiments, may be constructed of several layers of the same or different materials secured together. Particular examples of materials for theabsorbent portion14 will be given below.
• The shape and size of the[0029]absorbent portion14 shown in FIG. 1 may vary from embodiment to embodiment. In some embodiments, a largerabsorbent portion14, such as that shown in FIG. 1, may be designed to be cut or ripped by the user (i.e., by using scissors or taking advantage of perforation lines) to a size suitable for the individual user. In other embodiments, theabsorbent portion14, andperspiration shield10 as a whole, may be made in different sizes to accommodate the sizing requirements of different users.
• The[0030]attachment portion16 is adapted to attach to theside strap24 of thebra12. As will be described below in more detail, theattachment portion16 of FIG. 1 is a portion contiguous with theabsorbent portion14 that folds over itself and attaches to theside strap24 of thebra12. In order to facilitate attachment,fabric adhesive18 may be provided on portions of theattachment portion16. Theattachment portion16 may be made of the same or a different material than that of theabsorbent portion14 and may be made integrally with theabsorbent portion14 or attached by appropriate means during manufacture or before use. Fold lines (not shown in FIG. 1) may be formed in the attachment portion, if desired, to facilitate the folding-over of theattachment portion16. Thefabric adhesives18 may be any type known in the art and, particularly, may be any type of adhesive that does not irritate the skin because contact with skin may occur, either directly or by residue that may remain on the side straps24 of thebra12.
• The side straps[0031]24 oftypical bras12 are reasonably consistent in width, despite differences amongparticular bras12 insupport cup20 sizes and strap length. Therefore, an attachment portion of standard length (e.g., approximately 10-20 cm) may be sufficient to attach tomost bras12. However, as with theabsorbent portion14, theattachment portion16 may be made in a variety of dimensions to accommodate different sizes, and may also be made such that it may be cut down or torn down (e.g., using perforation lines) to an appropriate size by the user.
• Most side straps[0032]24 ofbras12 provide a hem at least on the bottom edge of the strap. If thebra12 includes a hem, it may be most convenient and effective to see that theattachment portion16 is securely fastened to the hem, because the hem is typically one of the more rigid portions of theside strap24.
• Additionally, although fabric adhesive is described here as one option for fastening the attachment portion to the[0033]side strap24 of thebra12, conventional fasteners such as pins, safety pins, bobby pins, and buttons or snaps integrated into theattachment portion16 may also be used. In addition, in some embodiments, the folded overattachment portion16 itself, without adhesives or additional fasteners, may be sufficient to retain theperspiration shield10 in place, particularly if theside strap24 of thebra12 is elastic and the tension in thestrap24 exerts a retaining force on theattachment portion16.
• In general, as shown in FIG. 1, the[0034]perspiration shield10 is wedged between thebra12 and the user's torso and is retained there by thebra12, such that it is (and typically remains) in contact with the user's skin and has less of a tendency to shift or change position. The wedging effect of thebra12 on theperspiration shield10 may improve its ability to effectively and consistently absorb perspiration.
• Although not required in all embodiments of the invention, the[0035]perspiration shield10 has a portion terminating incurved edge27 that rests in thebra cup20 and constitutes a breast portion, as was described above. Thus, theperspiration shield10 is anchored both by theattachment portion16 and by theabsorbent portion14 resting in thebra cup20. The wedging of theabsorbent portion14 in thebra cup20, in addition to allowing absorption of moisture from the side and breast areas, adds to the wedging effect described above and contributes to the overall stability of theperspiration shield10 during wear. In practice, the absorbent portion may extend at least several centimeters into thebra cup20 and, in general, may extend into thebra cup20 as far as desired, provided that it does not cause the user discomfort.
• FIG. 2 is a side elevational view of a[0036]perspiration shield100 according to another embodiment of the invention. In FIG. 2, and in other views, it should be understood that the two sides are, in general, mirror images of one another, unless otherwise noted. It should also be understood that the two sides or faces ofperspiration shield100, and other perspiration shields according to the invention, may have different absorptive properties in some embodiments.
• [0037]Perspiration shield100, likeperspiration shield10 described above, includes anabsorbent portion114 and anattachment portion116. Theabsorbent portion114 is of a substantially different shape than theabsorbent portion14 of the previous embodiment, and includes an inwardlycurved edge120 that serves as a breast portion. The inwardlycurved edge120 is substantially “C” shaped.
• [0038]Curved edge portion120 is adapted to fit into and around a part of the circumference of thebra cup20 to act as a breast portion. In so doing, thecurved edge portion120 of theabsorbent portion114 provides the same general function as the outwardlycurved edge27 ofperspiration shield10. That is, in addition to absorbing moisture,curved edge portion120 adds to the stability of theperspiration shield100 by resting in and around thebra cup20 and wedging theperspiration shield100 into place against the torso.
• [0039]Perspiration shield100 also includesfabric adhesive18 on theabsorbent portion114 just above theattachment portion116 and along the curved edge portion120 (i.e., so that thecurved edge portion120 may adhere to the bra cup20). Also shown are areas where adhesive cover strips122,124 may be placed over the adhesive18 to protect the adhesive18 from loss of properties before use. The adhesive cover strips122,124 are conventional and may comprise, for example, polyethylene, polypropylene, or another material, such as waxed or silicone coated paper, which will adhere only lightly to the adhesive18 to protect it without degrading the properties of the adhesive18 upon removal. Typically, the adhesive cover strips122,124 would be removed by the user before use of theperspiration shield100. Fabric adhesive18 may be omitted from the opposite side ofperspiration shield100, and other perspiration shields according to the invention, so as to avoid direct adhesion to the user's skin.
• [0040]Perspiration shield100 may be constructed in any of the ways thatperspiration shield10 may be constructed and, in particular, need not includefabric adhesive18 in some embodiments. Alternatively,perspiration shield100 could includefabric adhesive18 proximate to theattachment portion116, but not along thecurved edge120.
• Those of skill in the art will note that in some embodiments, the shape of[0041]perspiration shield100 may make it suitable for either the left side of the user's body or the right side of the user's. Therefore, in those embodiments, if perspiration shields100 are to be sold, they may be packaged so as to have an equal number of perspiration shields100 of each type (e.g., left-sided perspiration shields100 and right-sided perspiration shields100).
• FIG. 3 is a perspective view of[0042]perspiration shield100 as attached to thebra12 of a user U. As shown, thefabric adhesive18 along thecurved edge portion120 allows theperspiration shield100 to attach along thecup20 and a portion of theoverarm strap22. As shown,perspiration shield100 is also wedged against the user's torso by its fit inside thebra cup20.
• FIG. 4 is a side elevational view of a[0043]perspiration shield200 according to a further embodiment of the invention.Perspiration shield200 includes anabsorbent portion114 essentially identical to theabsorbent portion114 of theperspiration shield100. Theabsorbent portion114 has acurved edge120,fabric adhesive18, and adhesive cover strips122,124. However,perspiration shield200 does not include anattachment portion16,116. Instead,perspiration shield200 is held in place by thefabric adhesive18 and by the retaining forces exerted on it by the side straps24, overarm straps22, and cups20 of thebra12. FIG. 5 is a perspective view showingperspiration shield200 attached to thebra12 of a user U.
• In some embodiments of the invention, rigidity-improving features may be added to reduce or prevent folding, crinkling, and/or unwanted movement of the[0044]absorbent portion14,114. FIG. 6 is a side elevational view of a perspiration shield300 that includes rigidity-improving features. Perspiration shield300 is identical in most respects toperspiration shield200. Although rigidity-improving features are shown with respect to perspiration shield300, it should be understood that rigidity-improving features may be included in any embodiment of the invention, if desired.
• Perspiration shield[0045]300 includes apocket302 along the rearward edge of theabsorbent portion114. Inside thepocket302, anelongate rigidity tab304 having greater rigidity than the material of theabsorbent portion114 is installed. Theelongate rigidity tab304 may be, for example, a thin plastic (e.g., polyethylene (PE), polypropylene (PP), or polyethyleneterephthalate (PET)) tab, or a cardboard tab, among other potential materials. Theelongate rigidity tab304 provides some of the same functions as a collar stay, and, in general, materials used for conventional collar stays may be used for theelongate rigidity tab304. Thepocket302 andelongate rigidity tab304 may be made to any length and may also be contoured to follow the edge of theabsorbent portion114.Rigidity tab304 lengths in the range of approximately 5-10 cm or less would be typical, depending on the size of theabsorbent portion114. More than onepocket302 andrigidity tab304 may be provided.
• In some embodiments, the[0046]rigidity tab304 may be removable from thepocket302 so as to be reusable. In other embodiments, therigidity tab304 may not be removable from thepocket302. Additionally, as will be described below in more detail, some embodiments of perspiration shields10,100,200,300 according to the invention may be made, at least in part, of plastic materials, or of other relatively rigid materials or composites of materials. If a portion of theperspiration shield10,100,200,300 is made of a plastic material or another material capable of being selectively thickened, a certain portion of that material may simply be thickened so as to constitute a rigidity-improving portion. Additionally, arigidity tab304 may be embedded, laminated, or otherwise made a part of aperspiration shield10,100,200,300 without the inclusion of aspecific pocket302 for it.
• FIG. 7 is a perspective view of a[0047]perspiration shield400 according to another embodiment of the invention, shown as installed in thebra12 of a user U. In the view of FIG. 7, twoperspiration shields400 are shown, one on each side of thebra12 of the userU. Perspiration shield400 is absorbent and/or capable of wicking moisture away.Perspiration shield400 does not include an attachment portion or fold-over flap; instead,perspiration shield400 attaches to thebra12 by fabric adhesives and by the wedging effect between thebra cup20, thebreast portion402 of theperspiration shield400, and theside strap24 of thebra12. As shown, some of thebreast portion402 is arranged to rest in thebra cup20. Additionally, as in other embodiments,perspiration shield400 extends upward from theside strap24 andbra cup20 to cover a portion of the under arm area. Although both perspiration shields400 are not fully visible in the view of FIG. 7, the arrangement of theother perspiration shield400 is identical to that of theperspiration shield400 that is visible in FIG. 7.
• FIG. 8 is a side elevational view of one side of[0048]perspiration shield400. As shown,perspiration shield400 is generally rectangular in shape with rounded corners. The dimensions ofperspiration shield400 would generally be similar to those of other perspiration shields10,100,200,300 according to the invention. Additionally, although shown as being of unitary construction,perspiration shield400 may be comprised of several different layers of material, as will be described below in more detail.
• As in perspiration shields[0049]10,100,200,300 according to other embodiments of the invention,perspiration shield400 includesfabric adhesive18 on its lower edge. Thefabric adhesive18 is generally provided in an “L” shape, so that it extends along the lower edge404 of theperspiration shield400 as well as a portion of the forwardly-extendingedge406 of thebreast portion402. Also shown is the area where anadhesive cover strip422 would be attached to protect thefabric adhesive18 before use. With the arrangement of thefabric adhesive18 shown in FIG. 8, theperspiration shield400 attaches to theside strap24 and rests in and attaches to thebra cup20. As was described above, thefabric adhesive18 contributes to the attachment and stability of theperspiration shield400, but theperspiration shield400 is also held in place by the wedging effect of theside strap24 andbra cup20.
• FIG. 9 is a perspective view of another[0050]perspiration shield500, shown as attached to thebra12 of a userU. Perspiration shield500 is similar toperspiration shield400 in many respects and attaches to thebra12 in the same way asperspiration shield400. As inperspiration shield400 and other perspiration shields10,100,200,300 according to embodiments of the invention,perspiration shield500 is absorbent and is capable of absorbing or wicking moisture away.
• One difference between[0051]perspiration shield500 andperspiration shield400 is thatperspiration shield500 includes anadditional sleeve flap510 that extends upward and along the underside of the arm.Sleeve flap510 provides additional protection for the user's sleeves, and may be positioned so as to hang in the sleeve. Typically,sleeve flap510 would be comprised of an open-weave or lightweight material, and would be absorbent and/or capable of wicking perspiration away. However,sleeve flap510 may be comprised of the same materials of which the main portion of theperspiration shield500 is comprised. In some embodiments, thesleeve flap510 may be slightly wider than other portions of theperspiration shield500, and may widen as it extends upward or along the underside of the arm. Although shown in the context ofperspiration shield500, asleeve flap510 may be included in aperspiration shield10,100,200,300,400,500 according to any embodiment of the invention.
• Perspiration shields[0052]10,100,200,300,400,500 according to embodiments of the invention may be made of a variety of materials, depending on the degree of absorbance desired, the desired cost of the final product, and the designed wear duration. A number of absorbent and superabsorbent materials are known in related arts and are used, for example, in disposable towels and napkins, sanitary napkins, and hospital bed shields. Those of skill in the art will readily be able to select appropriate materials, and certain non-limiting examples of specific appropriate materials will be given below.
• As was described briefly above, perspiration shields according to the invention may be constructed of several layers of the same or different materials and may be sewn, laminated, fused, fixed with adhesives, or otherwise joined together to make the final product. FIGS. 10A-10D are sectional views illustrating the various layers of material that may comprise perspiration shields[0053]10,100,200,300,400,500 according to embodiments of the invention. The sections shown and described with respect to FIGS. 10A-10D may be used with any of the perspiration shields10,100,200,300,400,500 described above.
• FIG. 10A illustrates a perspiration shield construction, generally indicated at[0054]30, that includes three layers of material. A first layer ofmaterial32 is an open-weave or otherwise light fabric or material that is used as a backing material. Attached to thefirst layer32 is a thin,impermeable plastic layer34, on top of which is provided a thicker layer ofabsorbent material36. Typically, theabsorbent material layer36 would comprise the top surface of theabsorbent portion14,114. The threelayers32,34,36 may be attached together or grouped together in any fashion, as was described above.
• The section shown in FIG. 10A has certain advantages. The presence of a thicker layer of[0055]absorbent material36 backed by a substantiallyimpermeable layer34 prevents fluid from seeping through theprotective shield10,100,200,300,400,500. However, thefirst layer32 of material may have some absorbent properties and may prevent the user from having direct skin contact with plastic or other evaporation-retarding impermeable materials, which would prevent perspiration from building up against a plastic layer.First layer32 may also assist in wicking and evaporation of accumulated perspiration. In some embodiments of the invention,absorbent portion14,114 may comprise the full construction30 shown in FIG. 10A, whileattachment portion16,116 may comprise only thefirst layer32 of open-weave fabric material. With respect toperspiration shield500,sleeve flap510 may also comprise only thefirst layer32 of open-weave material.
• FIG. 10B illustrates another perspiration shield construction, generally indicated at[0056]40. Construction40 includes afirst layer32 of open-weave fabric material. Attached to thefirst layer32 is a thin,impermeable plastic layer34, on top of which a thicker layer ofabsorbent material36 is provided. Theselayers32,34,36 are illustrated as being the same or substantially the same as those of construction30 of FIG. 10A, although they may be different. Construction40 includes an additional layer of open-weave orthin fabric material32 on top of the thicker layer ofabsorbent material36. The additional layer of open-weave or thin fabric material would typically be the same material as that offirst layer32, although it may be different in some embodiments.
• In general, the[0057]dual layers32 of open-weave or light fabric material may provide additional benefits in the wicking and evaporation of perspiration. Using construction40, theabsorbent portion14,114 of theperspiration shield10,100,200,300,400,500 may comprise the full construction40, while theattachment portion16,116, if provided, may comprise one or both layers of open-weave fabric material32. If both layers of open-weave fabric material32 are used as theattachment portion16,116, they may be sewn, adhered, fused, or otherwise attached together.
• FIG. 10C illustrates another perspiration shield construction, generally indicated at[0058]50.Construction50 includes a layer of open-weave orthin fabric material32 with thicker layers ofabsorbent material36 attached on each side.Construction50 thus provides absorbance on both sides of theperspiration shield10,100,200,300. Because of the relatively softabsorbent material36 on both sides of theshield10,100,200,300,400,500construction50 may be particularly comfortable to wear. Additionally, because there is noimpervious layer34,construction50 may be cooler for a user to wear. As with the other constructions, the layer of open-weave orthin material32 alone may comprise theattachment portion16,116, or thesleeve flap510, if those features are provided.
• FIG. 10D illustrates another perspiration shield construction, generally indicated at[0059]60.Construction60 includes a thin, substantiallyimpermeable layer34, on both sides of which are attached thicker absorbent layers36. The substantiallyimpermeable layer34 in the center may prevent perspiration from migrating from oneabsorbent layer36 to theabsorbent layer36 on the reverse side. Usingconstruction60, theimpermeable layer34 may comprise theattachment portion16,116.
• In addition to the[0060]constructions30,40,50,60 illustrated in FIGS. 10A-10D, perspiration shields10,100,200,300,400,500 according to the invention may include other layers as necessary or desired to increase absorbance, to prevent migration of perspiration from one layer to another, or to provide an absorbent or otherwise appropriate skin-perspiration shield interface on both sides of theperspiration shield10,100,200,300,400,500. In most embodiments, regardless of the number of layers included, the overall thickness will not exceed a few millimeters, or another thickness that can be conveniently worn and readily concealed beneath outerwear.
• As an aid to concealment, perspiration shields[0061]10,100,200,300,400,500 according to the invention may be tinted or given concealing colors, such as various skin tones. Additionally, in some embodiments, perspiration shields10,100,200,300,400,500 may other concealing colors, such as standard clothing colors (e.g., white, black, pink, and red). Tinting may be accomplished by adding the appropriate portion of colored dyes to at least some of thevarious layers32,34,36 that comprise the perspiration shields10,100,200,300,400,500. Additionally, a separate layer or layers may be included solely for tinting purposes.
EXAMPLES
• Certain specific examples of perspiration shield construction may be helpful in understanding the kinds of materials that may be used in perspiration shields[0062]10,100,200,300,400,500 according to the invention. However, as was noted above, the examples presented here are not intended to be limiting; those of skill in the art may implement embodiments of the invention using different materials.
Example 1
• A perspiration shield having the general appearance and configuration of perspiration.[0063]shield10 of FIG. 1 was constructed using layer construction30 of FIG. 10A. (Certain dimensions will be given with respect to FIG. 2 because that figure better lends itself to dimension lines and because the particular dimensions are not critical.) Theperspiration shield10 has a length (e.g., dimension line L of FIG. 2) of approximately 25 cm, anabsorbent portion114 height (e.g., dimension line H of FIG. 2) of approximately 13 cm, anattachment portion16 length (e.g., dimension line AL of FIG. 2) of approximately 10 cm at the shortest point, and anattachment portion16 height (e.g., dimension line AH of FIG. 2) of 13 cm. Theattachment portion16 of this example was right trapezoidal in overall shape, with theattachment portion16 having a length of 17 cm immediately adjacent to the absorbent portion and decreasing therefrom along one edge to the 10 cm length at the parallel edge farthest from theabsorbent portion14. Theabsorbent portion14 had the overall D-shape shown in FIG. 1; dimensions given here refer to the broadest or widest point in the shape.
• The[0064]first layer32 of this example was constructed from a readily available open-weave disposable dry baby washcloth (Item #470; distributed by Toys“R”Us, Paramus, N.J., United States). In order to form the absorbent portion, a number of pantyliners were sewn to thefirst layer32/disposable washcloth using a zigzag stitch.
• The pantyliners are generally rectangular in overall shape, individually approximately 5 cm in width and 15 cm in length with curved ends on the thinner sides. Each pantyliner includes an absorbent layer and an integral plastic substantially impermeable layer; in essence, the pantyliner contains both[0065]layers34 and36 of construction30, and may also contain other layers as well. Because of the limited width of the individual pantyliners, four of them were sewn side-by-side to form theabsorbent portion114. Zigzag stitching was provided along each outer edge of theabsorbent portion14. Fabric adhesive was not provided in this particular example. Although several pantyliners were sewn side-by-side to form theabsorbent portion14, in other embodiments, the layers that comprise theabsorbent portion14 may be unitary.
• In testing, the relative rigidity of the pantyliners was found to substantially prevent unwanted crinkling and folding of the[0066]perspiration shield10. Additionally, the pantyliners carried a light fragrance. Fragrance may optionally be included in some embodiments of the invention.
Example 2
• A perspiration shield having the general appearance and configuration of[0067]perspiration shield10 of FIG. 1 was constructed using layer construction40 of FIG. 10B. Theperspiration shield10 of this example had the same general size and dimensions as that of Example 1, and was comprised of the same materials.
• On top of the layer of four pantyliners sewn side-by-side, an additional layer of open-weave[0068]disposable washcloth32 was sewn using zigzag stitching, forming layer construction40 of FIG. 10B. The two layers ofdisposable washcloth32 were sewn together in the areas not covered by the pantyliners to form theattachment portion16, as was described above.
Example 3
• A perspiration shield having the general appearance and configuration of[0069]perspiration shield100 of FIG. 2 was constructed using layer construction30 of FIG. 10A. The layers, materials, and overall dimensions were approximately the same as those for Example 1. A single pantyliner was cut to an appropriate curved shape and was sewn horizontally (i.e., with respect to the orientation of the other pantyliners) to form the lower, breast portion of thecurved edge120. All edges of the cut pantyliner were hemmed with zigzag stitches, which also served to attach the pantyliner to the disposable washclothfirst layer32.
Example 4
• A perspiration shield having the general appearance and configuration of[0070]perspiration shield100 of FIG. 2 was constructed generally in accordance withlayer construction60 of FIG. 10D. The overall dimensions were approximately the same as those of Example 1. However, the perspiration shield of this example included apocket302 andrigidity tab304, as will be described below.
• A floor protection pad for adult dogs was used as the substantially[0071]impermeable layer34. The protection pad is similar to hospital bed protection pads and comprises a thin outer (i.e., floor-facing) layer of impermeable plastic attached to a very slightly thicker inner layer of absorbent material. The floor protection pad was cut to the general shape shown in FIG. 2, and a portion of the floor protection pad was shaped to form theattachment portion116. (Thus, theattachment portion116 included the thin absorbent layer of the floor protection pad as well as the floor protection pad's impermeable layer.)
• On each side of the floor protection pad, a cut-to-shape portion of a smooth, soft, single-ply paper napkin approximately 1 mm thick was sewn with zigzag stitching to the floor protection pad to serve as an[0072]absorbent layer36, resulting inoverall layer construction60. Because of the thin absorbent layer provided by the floor protection pad, the absorbent layer on one side of the perspiration shield of this example was slightly thicker than theabsorbent layer36 of the other side.
• In addition to those features, a[0073]pocket302 with a length of approximately 7 cm and a width of approximately 2 cm was formed in theabsorbent portion114 approximately 2 cm from the right edge of the absorbent portion114 (with respect to the coordinate system of FIG. 6) by single lines of stitching through the perspiration shield, defining a partial pocket with two long sides and a short closed end. In order to open one end of the pocket for use, a slit parallel to the line of stitching defining the short closed end was cut in the appropriate place in the napkin serving as anabsorbent layer36, thereby defining thepocket302 between the napkin serving as theabsorbent layer36 and the floor protection pad serving as the substantiallyimpregnable layer34 of theabsorbent portion114.
• A conventional collar stay approximately 8 cm long and 1 cm wide was inserted into the[0074]pocket302 to serve as arigidity tab304. In this example, the collar stay serving as therigidity tab304 was slightly longer than thepocket302 in order to facilitate removal. However, as was described above, therigidity tab304 may be shorter than thepocket302 and may be completely sewn into it.
• Testing demonstrated that although the[0075]perspiration shield100 of this example did not include fabric adhesives, fabric adhesives may be useful to secure theperspiration shield100 of this example. Therigidity tab304 was used because thisperspiration shield100 was thinner and, thus, more prone to folding and crinkling than those of Examples 1-3.
Example 5
• A perspiration shield having the general appearance and configuration of[0076]perspiration shield100 of FIG. 2. The overall dimensions were approximately the same as those of Example 1. The layer construction of theperspiration shield100 according to this example differed somewhat from the general cases presented in FIGS. 10A-10D, as will be explained below in more detail.
• The base or first layer of the[0077]perspiration shield100 according to this example comprised a cut-to-shape portion of a smooth, soft, single-ply paper napkin approximately 1 mm thick, rather than the disposable washcloth of Example 1. The single-ply paper napkin serving as the first layer had a closed weave as compared with the disposable washcloth, but its absorbance and wicking capabilities were found to be similar or equivalent in the context of the invention to those of the open-weave disposable washcloth. Theattachment portion116 was comprised entirely of the paper napkin.
• Attached to the first layer of paper napkin side-by-side by means of their existing adhesive were one and one half thin feminine napkins. At the[0078]curved edge120, the paper napkin first layer was cut so as to extend approximately 1 cm beyond the corresponding cut and shaped curved edge of the feminine napkins. The additional 1 cm fringe of paper napkin without the additional padding of the feminine napkins was found to insert well under the bra, so as to provide more stability.
• The feminine napkins used in this example are generally comprised of an enveloping plastic layer, inside of which is a thickness of more absorbent material. On one side, the enveloping plastic layer is continuous and coated with fabric adhesive; on the other, perforations allow moisture to penetrate and be absorbed. In this example, the feminine napkins were not secured to the first or base layer with anything other than their existing adhesive. However, in some embodiments, the existing adhesive may be reinforced by additional adhesive, stitching, fusion, or other methods of attachment.[0079]
• After testing, it appeared that the long-term tensile strength and wet tensile strength of the paper napkin were less than those of the disposable washcloth used in the other examples. Despite the apparent difference in strength between the disposable washcloth and the paper napkin of this example, the paper napkin may be less expensive than the disposable washcloth and, thus, may be desirable in some embodiments.[0080]
Example 6
• A perspiration shield having the general appearance and configuration of[0081]perspiration shield100 of FIG. 2 was constructed generally in accordance withlayer construction50 of FIG. 10C. The overall dimensions were approximately the same as those of Example 1.
• The first or base layer of[0082]material32 in this example was the same disposable washcloth as used in Example 1. On each side of the first or base layer, double-thickness cut sections (i.e., two plies per side) of thick, smooth paper napkins were sewn with straight stitches in order to act asabsorbent layers36 of theabsorbent portion114, forminglayer construction50. Additionally, in order to promote adhesion between thefirst layer32 and the napkins acting asabsorbent layers36, rows of straight stitches extending parallel to dimension line H of FIG. 2 were sewn through theabsorbent portion114 at approximately 1.5 cm intervals. Approximately 10 lines of straight stitches were used in total. As in previous examples, thefirst layer32 alone comprised theattachment portion116. Unlike in Example 4, thefirst layer32 and theabsorbent layers36 terminated at the same point along thecurved edge120. Although theperspiration shield100 of this example was fabricated without rigidity-improving features such aspocket302 andrigidity tab304, such features could be included.
• As will be appreciated by those of skill in the art, Examples 1-6 were constructed of readily available materials and consumer products having general properties that make them suitable for inclusion in perspiration shields[0083]10,100,200,300,400,500 according to embodiments of the invention. However, perspiration shields10,100,200,300,400,500 according to embodiments of the invention may be constructed from other suitable materials, and raw materials, as well.
• While the invention has been described with respect to certain embodiments and particular examples, the embodiments and examples described are intended to be exemplary, rather than limiting. Modifications and variations may be made within the scope of the appended claims.[0084]
