Definitions

  • the present invention relates to a clothing shield, and more particularly to a disposable clothing shield that protects clothing from stains and is visibly masked through the clothing.
  • clothing shields there are various types of clothing shields, and they include both disposable and reusable types. Generally, they comprise a liquid-impervious outer cover and an absorbent medium attached thereto. In the past, these shields have generally been made of a cloth-like material and/or a cellulosic material. More recently, some shields have included thermoplastic materials in their structure.
  • Another problem with current clothing shields is that the external surface, generally one side of the liquid-impervious outer cover, is visually discernible through the clothing of the wearer. Either the geometric shape is outlined through the clothing, or a particular design pattern on the outer cover is reflected through the clothing.
  • the present invention provides a clothing shield that is relatively lightweight and relatively thin so as to be comfortably worn by the wearer. Because the clothing shield is also relatively thin, it does not project or outline a pattern on the clothing that is easily seen by others.
  • the present invention also provides a clothing shield that has one surface that visually masks the shield through the clothing.
  • the surface randomly scatters light reflected therefrom so as not to reflect or radiate a geometrically visible pattern or shape of the shield through the clothing.
  • an article for protecting clothing against stains and the like comprising an absorbent medium and a liquid-impervious outer cover adjacent to the absorbent medium.
  • On the exposed side of the cover there is a unique surface that randomly scatters light reflected therefrom, thereby visually masking the article through the clothing.
  • a method for making an article for protecting clothing against stains and the like comprises the steps of providing a liquid-impervious outer cover, and providing an absorbent adjacent the outer cover. There is created on an exposed side a masking surface that randomly scatters light reflected therefrom, thereby to visually mask the article from being seen through the clothing.
  • clothing shield 2 of the present invention is illustrated and generally comprises liquid-pervious bodyside liner 4, liquid-impervious outer cover 6, and absorbent medium 8 disposed between liner 4 and cover 6.
  • Bodyside liner 4 is made of a liquid-pervious thermoplastic material having a basis weight from about 0.3 to about 1.5 ounces per square yard, and a thickness generally from about 10 to about 20 mils.
  • bodyside liner 4 is a hydrojet-entangled layer of thermoplastic material.
  • the thermoplastic material can be polyethylene or polypropylene, and more preferably is polyester.
  • the hydrojet-entangled process results in a tangled-like web of thermoplastic microfibers that have increased softness over other processes. These particular types of microfibers refer to small diameter fibers having a diameter not greater than about 100 microns, preferably a diameter from about 0.5 to about 50 microns, and more preferably a diameter from about 4 to about 40 microns.
  • the hydrojet-entangling process involves the use of an air forming process, wherein the bonding is due to fiber entanglement caused by water jets.
  • hydrojet-entangled process provides a thermoplastic fibrous layer that is very soft and comfortable against the skin.
  • One type of hydrojet-entangled web is Sontara manufactured by E. I. Du Pont Textiles Fibers Department of Wilmington, Delaware.
  • bodyside liner 4 can be made include spunbonded thermoplastic materials, such as spunbonded polyethylene and spunbonded polypropylene.
  • Bodyside liner 4 can further be a nonwoven web or sheet of polyolefin fibers, such as polypropylene, polyester, polyethylene, Rayon, and the like. It may also be a nonwoven web of synthetic or natural fibers or a blend thereof, a plastic film with perforations or an expanded plastic webbing material or a scrim material.
  • polyolefin fibers such as polypropylene, polyester, polyethylene, Rayon, and the like. It may also be a nonwoven web of synthetic or natural fibers or a blend thereof, a plastic film with perforations or an expanded plastic webbing material or a scrim material.
  • Absorbent medium 8 is preferably made of a thermoplastic material treated with a surfactant so as to be hydrophilic.
  • absorbent medium 8 comprises meltblown polypropylene.
  • Other materials of which absorbent medium 8 can be made include coform materials, which are a blend of wood pulp fluff and thermoplastic fibers with, if desired, a superabsorbent material.
  • the preferred meltblown polypropylene can also include a super­absorbent material in order to increase its absorbency.
  • Absorbent medium 8 can have a basis weight from about 25 to about 250 grams per square meter, and more preferably from about 50 to about 150 grams per square meter.
  • the surfactant for treating the thermo­plastic fibers can be any suitable surfactant, such as Aerosol OT manufactured by American Cyanimid, or Triton X-102 manufactured by Rohm and Haas, or the like.
  • the amount of surfactant is generally from about 0.1 to about 1.0 percent by weight of the total weight of absorbent medium 8.
  • the concentration or layering of absorbent medium 8 can be selectively varied, such as by increasing the concentration or amount of absorbent in the central portion of shield 2.
  • Absorbent medium 8 can also comprise other agents, such as fragrance, antimicrobial materials, odor-neutralizing materials, and anti-perspirant agents.
  • agents such as fragrance, antimicrobial materials, odor-neutralizing materials, and anti-perspirant agents.
  • One method of including these would be by microencapsulating in water-soluble capsules and which are released on contact with moisture.
  • agents include bacteriocides, fungicides, for example, metal compounds of zinc, copper, aluminum, or cobalt.
  • Other agents include quaternary ammonium compounds, sorbic acid, citrates, pH altering agents, and activated carbon.
  • absorbent medium 8 being made of other suitable absorbent materials, for example, a cellulosic material such as an air-formed batt of wood pulp fibers, a nonwoven web of synthetic or natural fibers, a composite of meltblown fibers mixed with a cellulosic material, or a blend of cellulosic material with staple textile fibers such as Rayon.
  • absorbent medium 8 may also include super­absorbent materials, which include grafted starch, starch poly­acrylic acid, grafted methyl cellulose, modified polyvinyl alcohols, polyacrylic acid salts that are cross-linked to form absorbent polymers, and the like.
  • Absorbent medium 8 may also be made of a foam-type material, such as polyester, polyurethane, and ethylene vinyl acetate with polyester or polyurethane.
  • Outer cover 6 preferably comprises a film of thermoplastic material having a thickness from about 0.3 to about 1.3 mils.
  • One side of outer cover 6 can be provided with an adhesive for bonding absorbent medium 8 thereto.
  • the adhesive is a soft-type adhesive that does not diminish the softness or flexibility of clothing shield 2.
  • An example of this type adhesive is Dispo-Melt 34-5517 manufactured by National Starch Company of Bridgewater, New Jersey, or Findley Adhesive 952-383 manufactured by Findley Adhesives of Brookfield, Wisconsin. This adhesive is applied in any suitable manner to one side of outer cover 6 and then absorbent medium 8 is registered thereon so as to provide a peripheral por­tion 10 of outer cover 6 about absorbent medium 8.
  • bodyside liner 4 is placed over absorbent medium 8 and extends outwardly over absorbent medium 8 to provide a peripheral portion 12 that is generally contiguous with peripheral portion 10.
  • Both peripheral portions 10, 12 have respective peripheral edges 14, 16, as illustrated in Figure 3.
  • outer cover 6 and liner 4 may be interchanged.
  • the adhesive could be applied in any suitable manner to one side of liner 4, and then absorbent medium 8 would be registered thereon to provide a peripheral portion.
  • outer cover 6 is placed over absorbent medium 8 and extends outwardly thereover to provide another peripheral portion.
  • peripheral portions 10, 12 are then joined together with a suitably soft adhesive, such as that earlier mentioned above, along a bondline 18 ( Figure 3) that is inwardly spaced from peri­pheral edges 14, 16.
  • the inward placement of bondline 18 permits peripheral edges 14, 16 to be free and loose, thereby providing a soft, comfortable edge about clothing shield 2.
  • Bondline 18 also serves as a liquid-impervious border about clothing shield 2.
  • bondline 18 is spaced inwardly from peripheral edges 14, 16, a distance from about 0.5 to about 5.0 millimeters.
  • the peripheral portions 10, 12 can also be adhered or bonded along their total surface areas between the edge of absorbent medium 8 and peripheral edges 14, 16.
  • bondline 18 was described as a line of adhesive applied between peripheral portion 10 and peripheral portion 12, the bond could also be provided by thermal bonding along bondline 18.
  • outer cover 6 can comprise a film of thermoplastic material such as polyethylene, polypropylene, or polyolefin copolymers such as ethylene vinyl acetate, ethylene methyl acrylate, ethylene ethyl acrylate, polyvinyl chloride, Nylon, and the like.
  • One of the unique features of the present invention is the provision of a masking surface on the exposed side of outer cover 6, which would be adjacent the clothing.
  • the present invention provides a masking surface 20 on the external side of outer cover 6 that absorbs some of the incident light on outer cover 6 and/or randomly scatters light reflected from outer cover 6. Because the reflected light is randomly scattered, there is no clear or delineated geometric pattern or shape visually per­ceivable through the clothing.
  • Masking surface 20 is provided by a spunbonded thermoplastic layer joined to the exposed side of outer cover 6, the exposed side being that side opposite absorbent medium 8.
  • the spunbond process provides a random distribution of thermoplastic microfibers as a coherent web.
  • Spunbonded thermoplastic microfibers refer to small diameter fibers having a diameter not greater than about 100 microns, preferably a diameter from about 10 to about 50 microns, and more preferably a diameter from about 12 to about 30 microns.
  • the spunbond microfibers are made by extruding a molten thermoplastic material as filaments through a plurality of fine capillaries of a spinnerette with the diameter of the extruded filaments then being rapidly reduced as by, for example, eductive drawing or other well known spunbonding mechanisms.
  • a description of a spunbond process is disclosed in U.S. Patent No. 4,340,563, which patent is incorporated by reference herein.
  • outer cover 6 is a two-layer composite comprising an ethylene methyl acrylate extruded onto a spunbonded polypropylene layer.
  • the ethylene methyl acrylate layer can be any suitable color, and preferably is beige-colored, and the spunbonded polypro­pylene is perferably white in color.
  • the spunbonded polypropylene can have a basis weight from about 0.4 to about 0.8 ounces per square yard.
  • Figure 1 is a photographic view of masking surface 20 of outer cover 6. As can be clearly seen, and to a somewhat lesser degree in Figure 4, the white-colored spunbonded propylene is randomly dispersed on the darker, or beige-colored, surface of the thermoplastic film layer.
  • Masking surface 20 may be provided by other processes other than a spunbond process, such as an intermittent meltblown process, or hydrojet-entanglement process.
  • the masking surface 20 is provided with a transparent adhesive 25 indicated as dots ( Figure 6) and a peel strip 22.
  • Figure 6 illustrates peel strip 22 in two sections, with one of the sections being partially removed to expose the transparent adhesive 25.
  • the transparent adhesive 25 is preferably a soft hot-melt adhesive, such as HM1972 manufactured by The H. B. Fuller Company of St. Paul, Minnesota, or National Starch Dispo-Melt 34-2841 manufactured by National Starch Company of Bridgewater, New Jersey.
  • the adhesive may be applied on the total surface area, or in elongate strip areas or other segmented or selected sections.
  • Peel strip 22 is preferably a silicone-coated cellulosic release paper that will adhere to transparent adhesive 25 and, upon removal, not degrade or diminish the adhesive characteristic.
  • clothing shield 2 has a pair of slits 24 disposed on generally opposite sides thereof.
  • Each slit 24 has a length from about 1/4 inch to about 1 inch, and as illustrated in Figure 2, a dashed creaseline 26 indicates where clothing shield 2 would be folded in order to fit inside the under­arm seam area of a garment or piece of clothing, as illustrated in Figure 7. In addition to folding, it could be pinched, embossed, heat-sealed, or the like.
  • Slits 24 aid in placement of clothing shield 2 within the garment by allowing the shield to be easily folded therealong and to aid in staying in place in the garment.
  • the top approximate one-third of cloth­ing shield 2 is of a different type oval shape from the bottom approximate two-thirds of shield 2.
  • This design results in an anatomically configured shield that conformably fits in the under­arm seam area of a garment, as illustrated in Figure 7.
  • the uppermost oval-shape portion as viewed in Figure 2, of shield 2 is from an oval having a more rounded or fatter shape than the oval-shape of the lowermost portion of shield 2.
  • the joinder of these two oval-shapes is along creaseline 26, which is measured from the topmost edge of shield 2, as viewed in Figure 2, downwardly a distance along the longitudinal centerline. This distance is from about 25% to about 45% of the total length, as measured along the longitudinal centerline, of shield 2.
  • shield 2 is symmetric about its vertical longitudinal axis and asymmetric about its transverse horizontal axis, as illustrated in Figure 2. It is the asymmetric shape that results in the anatomically configured embodiment of the present invention.
  • the anatomical shape or configuration serves not only to provide a conformable fit to the underarm seam area, but also to maximize protection between the clothes and body.
  • the overall weight of clothing shield 2 is from about 1.5 grams to about 5 grams, and has an overall thickness from about 0.75 millimeters to about 3.0 millimeters.
  • Clothing shield 2 is also intended to be disposable after use.
  • stains prevented by use of shield 2 are body perspirant stains, and residue stains from deodorants and anti-perspirants.
  • clothing shield 2 has been described primarily for use as an underarm shield, it can have use in other areas, such as wound dressings, incontinence products and the like.
  • the masking effect provided by the present invention can also be used on other articles or products that would preferably be masked from view.
