Definitions

  • This present invention relates to undergarments in general, and more specifically to women's paper-like disposable undergarments having a moisture repellent shield and an absorbent liner for use during a woman's menstrual period.
  • the truly disposable undergarment incorporating a moisture repellent shield and an integral absorbent liner that is used in combination with a sanitary napkin or tampon is still sought after and fills a long felt feminine need.
  • Greene teaches a disposable undergarment made from a single sheet of nonwoven cellulous material, such as paper. A band of elastomeric material is sewn around the waist portion and similar material around the leg open ⁇ ings. A detachable pouch is also taught for storage and disposal.
  • Pigneul et al utilize a disposable article attached to the wearer by the use of a removable belt. The pad is a laminated structure using absorbent cloth made of cellulose foam with a polyethylene film backing hook and loop tape is used as the method of attachment.
  • La Fleur employs a cotton material pa ty with a cut-out crotch in which a disposable paper crotch mem ⁇ ber is inserted.
  • the removable section is held in place by Velcro-like elements being hooked in holes of the removable member.
  • Larson in U. S. Patent 3,599,640 teaches a dispos ⁇ able waist supported garment including an integral ab ⁇ sorbent crotch pad.
  • the garment is made of a nonwoven paper material with sufficient " thermoplastic material incorporated by spraying, or the like, to allow heat sealing around the edges, gathered so as to be sufficiently stretchable to hold the garment in place.
  • the integral pad is formed of a double layer of paper material, the same as formed by the body of the garment. In one em ⁇ bodiment, elastic threads are disposed between the layers and spot sealed in place.
  • Mc Curry uses a unitary sheet of nonwoven material with carding staple fibers having a set of scrim warp threads parallel and perpendicular allowing stretch in a predetermined direction.
  • under ⁇ garments are worn by women to hold a sanitary napkin in place, however, when the napkin becomes saturated, . the excess body fluid often overflows onto t e crotch area of the garment and then to outer clothing.
  • the present invention prevents this overflow from reaching the outer clothing, as an absorbent cotton liner is in direct contact with the outer surfaces of the napkin and is larger in size than the periphery of the napkin.
  • the absorbent nature of the cotton liner retains the fluid in the localized region and the moisture repelling shield prevents any leakage to the body of the disposable garment therefore, the possibility of reaching the outer clothing is eliminated. This is true if an internal tampon is used by the women as the protection afforded is identical.
  • this garment is adaptive to most conventional styles of undergarment, such as so-called, "Bikini”, “Brief”, or “Hipster” styles in popular use today.
  • An important object of the invention is the use of a material that is durable, breathable, flexible and tear resistant. This object is achieved by the utilizat ⁇ tion of a nonwoven paper material that is in wide use for such items as food service towels or hospital gowns, replacing cotton towels, sponges and throw-away paper.
  • This material may also be cleaned after soiling by washing it by hand, making its use wide-spread enough to be mass produced and cost effective, therefore, easily adaptable to women's undergarments.
  • Another object of the invention is the use of a cotton absorbent liner in the area of the crotch. Cotton fiber, loosely woven is highly absorbent and ideal for such usage and its cost is also economical.
  • Still another object of the invention is the aesthetic value of the non-woven paper material.
  • This material may be employed in a wide variety of colors and textures, enhancing the application as the normal colors for this type of undergarment may be duplicated and the addition of lace type fabric may border the waist, again duplicating the fashions of today.
  • Yet another object of the invention provides an upwardly extending absorbent/repellent area in the crotch that is effective when the wearer is sleeping, particu ⁇ larly when a large size sanitary napkin is being used thereby preventing soiling of bed linen.
  • FIGURE 1 is a front elevational view of the pre ⁇ ferred embodiment.
  • FIGURE 2 is a side elevational view of the pre- ferred embodiment.
  • FIGURE 3 is a cross-sectional view taken along lines 3-3 of FIGURE 2 with the material thickness slightly exaggerated for clarity.
  • FIGURE 4 is a cross-sectional view taken along lines 4-4 of FIGURE 2 with the material thickness slightly exaggerated for clarity.
  • FIGURE 5 is a. front elevational view of the fourth embodiment with the front partially cut away showing the various layers of material.
  • FIGURE 6 is a side elevational view of the fourth embodiment with the side partially cut away depicting the hook and loop tape.
  • FIGURE 7 is a cross sectional view taken along lines 7-7 of FIGURE 6 with the material thickness slightly exaggerated for clarity.
  • FIGURE 8 is a cross sectional view taken along lines 8-8 of FIGURE 6 with the material thickness slightly exaggerated for clarity.
  • FIGURE 9 is a cross sectional view taken along lines 9-9 of FIGURE 6 with the material thickness slightly exaggerated for clarity.
  • the best mode for carrying out the invention is presented in terms of a preferred, second, third and fourth embodiment. All of the embodiments are basically the same except the second embodiment differs in basic body material.
  • the third embodiment omits the moisture repellent shield and the fourth embodiment splits the undergaremtn on the sides and adds hook and loop tape to hold the sides together.
  • the preferred embodiment as shown in FIGURES 1 through 4 is comprised of a body 20 of nonwoven, breath ⁇ able, flexible paper formed to fit the lower torso of a woman.
  • the body 20 has an opening 22 for the waist on the top and a pair of leg openings 24 on the bottom, otherwise, the body is unitary.
  • the flexible paper material is absorbent in nature and porous, made with a plurality of holes.
  • the cellulose, or synthetic, fibers are layered together providing sufficient air space to be porous and also resilient, allowing the material to feel soft to the touch.
  • An alternate accept ⁇ able material, having the same characteristics, is known as PELLON.
  • the shape of the undergarment is configured so as to fit snugly around one's body.
  • a stretchable elastic waistband 26 is sewn around the waist opening 22.
  • This band 26 is formed of a stretchable, resilient material, such as synthetic rubber, woven into a fabric strip that allows the band to stretch in length and return by its own memory to the original dimension. Any stretchable material is included, such as elastic thread, stitched to form an elastic band or simple rubberband may be utilized in single or double ply.
  • a lace fabric 28 may be added to or incorporated into the elastic waistband 26. While this lace is illustrated only on the waist in FIGURE 2, it is well known in the art and is formed in a myriad of shapes, sizes, and patterns, any of which would be applicable to this invention as its utility is purely ornamental .
  • a pair of stretchable elastic leg bands 30 are sewen around the leg openings 24 of a size to allow the garment to comfortably slip over the leg and yet fit tightly for comfort of the wearer.
  • the material and the addition of lace fabric 28 is the same as described above.
  • the moisture repellent shield 36 is conformally attached to the body 20 between the leg openings 24.
  • the shield 36 may be made of any non-porous resilient mate ⁇ rial however, it is preferably made of a thermoplastic composition consisting of a non-woven material of polyethylene fibers.
  • An absorbent liner 32 is attached on top of the shield 36 between the leg openings 24 and continue upwardly toward the waist opening 22, perhaps one-third the distance between the center of the crotch and the top of the garment.
  • the front portion of the liner 32 and shield 36 distend upwardly somewhat higher than the back.
  • the liner 32 is preferably made of a loosely knit cotton fabric that is highly absorbent. The cotton fibers are twisted into threads and woven in a loosely knit manner. Cotton is well known for its ability .to absorb "fluids and the arrangement of having the liner 32 on the inside next to the body or sanitary pad allows women's normal body fluid to be sanitarily contained within the fibers, and when it becomes saturated, may be easily discarded. Attachment of the elements of the undergarment is accomplished by an attachment means, such as by sewing with thread, preferably using stretchable type thread that allows some give to the seams .
  • the stitching is accom ⁇ plished in a zigzag manner, therefore, when pulled taut, the thread pivotly rotates at each apex yieldingly allowing movement without reaching the expansion limitations of the thread.
  • the flexible paper material is folded over at the raw edges into a hem 34, best illustrated in FIGURES 3 and 4, and is cut from separate pieces, preferably, a front, back and crotch, to form the undergarment. This construction allows the cotton absorbent liner 32 and moisture repellent shield 36 to be easily hemmed along with the body pieces to make a smooth even seam.
  • attachment means may be employed. These other means include gluing the elements together with a suitable adhesive, securing them together with an adhesive strip or tabs, or by using a heat bonding process.
  • the second embodiment is identical to the preferred embodiment except the material for the body 20 is replaced by a synthetic woven fiber such as nylon or rayon.
  • the balance of the invention remains the same the difference being only in the base material which has no effect upon the utility, only a cost impact on the raw materials.
  • the third embodiment again is identical to the first embodiment except the moisture repellent shield 36 is omitted. This embodiment is directed to the utility of travel where disposable undergarments are convenient and also at any time where slight vaginal discharge is present other than a normal menstrual flow. '
  • the fourth embodiment is illustrated in FIGURES 5 through 9 and differs in construction by having both sides of the undergarment split and overlapped.
  • the body 20 is then held together by a strip of hook and loop tape 38 better known by its registered trademark VELCRO.
  • the hook side of the tape 38 is attached on one side of the body 20 and the loop side of the tape 38 is attached on the other allowing easy attachment and removal.
  • the garment When the garment is made, it is in a one piece form with a top and a bottom.
  • the sides have circular cutouts that when mated together form the openings for each leg.
  • the top and bottom form the waist opening each having the same elastic band 26 and 30 as the preferred embodi ⁇ ment as well as the other elements.
  • This split configur ⁇ ation allows the undergarment to be put on much like a diaper for bedridden patients and handicapped people where slipping the garment over the legs is awkward or inconvenient.
  • This embodiment is also advantageous for women wearing panty hose or slacks, over the top of the undergarment that would normally require removal of both legs in order to replace the garment once it was worn.
  • the cotton absorbent liner 32 may also be made of rayon or nylon. Hence, it is described to cover any and all modifications and forms which may come within the language and scope of the appended claims.
