Definitions

  • ABSTRACT A tampon having an absorbent body which is an agglomerate of pieces of absorbent foam, said agglomerate being held together by an overwrap which has water frangible closures that are maintained before use and in vivo but open up when the tampon is agitated in an excess of water such as a standard sewage disposal system.
  • This invention relates generally to absorbent pads designed to be disposed of in a sewage system. More particularly, it concerns absorbent devices wherein the absorbent body is an agglomerate of distinct and separable pieces of foam or sponge encased by an overwrap.
  • absorptive materials are used in the single-use absorptive products, various fibers being the most commonly used. Although fibrous products present some water closet disposal problems, sponge, sponge-like, and plastic foam products present greater water closet disposal problems due to the fact that they do not readily break down in a water closet system, and thus are more prone to clog water closet systems.
  • a catamenial device comprising an absorbent body which is an agglomerate of pieces of threedimensional cellular absorptive material, a fluidpermeable overwrap encasing the absorbent body, and means of egress from the overwrap for the pieces of absorptive material.
  • the means of egress is closed to the passage of the pieces of absorptive material before and during use and adapted to be opened upon disposal in water, whereby the pieces remain encased before and during use and are disgorged and separated from the overwrap upon disposal in a water closet.
  • FIG. 1 is a fragmentary perspective of a tampon of this invention
  • FIG. 2 is a cross-sectional elevational view of the tampon of FIG. 1 during one stage of its formation;
  • FIG. 3 is a cross-sectional elevational view of an alternate embodiment tampon at one stage of its formation
  • FIG. 4 is a fragmentary perspective of a fully formed tampon of FIG. 3;
  • FIG. 5 is a fragmentary perspective view of another tampon of this invention.
  • tampon 20 is shown as an absorbent device of this invention.
  • the tampon 20 has an absorbent body 21 which is an agglomerate of pieces 22 of three-dimensional cellular absorptive material encased by overwrap 23 which can be made from a rectangular piece of overwrap material which is folded over edge to edge and held in the tubular-shape thus formed by longitudinal seam 26.
  • the overwrap 23 has means of egress for the pieces 22, one form of the means of egress being an opening end 28.
  • a withdrawal string 24 can be attached to the closed end 29 of the tampon 20 in any manner well known in the tampon art, for example, threading a double string through the closed end 29 to form a loop and passing the free ends of the string 24 through the loop or fixing the string 24 to the overwrap 23 by sewing it or bonding it thereto sufficiently to withstand forces encountered during withdrawal.
  • the opening end 28 is a closure formed by gathering the terminal end of the overwrap and holding the gathered overwrap together with a water frangible (i.e., that which is opened, broken, or destroyed by water) adhesive in order that the closure is maintained before and during wearing of the tampon 20 and is opened when tampon 20 is deposited in a standard water closet.
  • a water frangible i.e., that which is opened, broken, or destroyed by water
  • the water frangible closures described herein, such as opening end 28, are means of egress from the overwrap 23 for the pieces 22 and are substantially closed to the passage of pieces 22 before and during use of the tampon.
  • the water frangible closure is opened by the swirling water in a flushed water closet or by a repeated dunking of the tampon 20 in the body of water in a water closet.
  • the expression gathering as used above is intended to include any bringing together of the overwrap at a longitudinal end to form a closure of the overwrap at that end, e.g., a closure in which the overwrap is omnidirectionally gathered radially inwardly as if drawn by a draw string; a fin seal wherein the terminal end is flattened to a single plane by forces perpendicular to the plane; a lap joint wherein the terminal end is folded inwardly and diametric portions of the end overlap, etc.
  • a terminal end of the overwrap or any portion of the overwrap can be any extremity or margin of the overwrap, such as is indicated by end 36 in FIG. 4.
  • the water frangible closure can be formed with a water frangible adhesive 25.
  • the tampon 20 at one stage of its formation can be such as shown in FIG. 2 where the overwrap 23 is tubularly shaped and has a closed end 29 which can be, but need not necessarily be, water frangible. If not water frangible, the closed end 29 can be formed by any convenient means such as sewing that end shut or, if desired, by bonding it with non-water soluble adhesives.
  • An agglomerate of pieces 22 of absorptive material comprising an absorbent body 21 is placed within the bag-shaped overwrap and the opening end 28 is gathered to form a closure which is maintained by the water frangible adhesive 25 shown in FIG. 1.
  • the overwrap 23 can be loose about the agglomerate, i.e., it does not have to form a tightly fitting overwrap with tensile forces therein. In fact, it can be advantageous to make the overwrap 23 oversized so that it is loose about the absorbent body 21 and essentially unstressed. An oversized overwrap tends to give the tampon a fluffy, soft feeland impression. An oversized overwrap also provides room for expansion of the absorptive material should it happen to be wet-swelling so that its absorptive capacity may be maintained.
  • an overwrap 30 is slightly longer than that required for the embodiment of FIG. 1 so that a portion of the overwrap can be made reentrant, i.e., folded around one end of the agglomerate and inwardly through a portion of the agglomerate.
  • that part of the overwrap which is not reentrant is the outer portion of the overwrap.
  • the overwrap also can be tubularly shaped and have a closed end 29.
  • the absorbent body 21 is placed within the bag-shaped overwrap and the agglomerate of pieces 22 is shaped to form therein a cavity 31 wherein the reentrant portion 34 of the overwrap 30 is placed such that the terminal end 36 of the overwrap 30 is the innermost end of the reentrant portion 34 of the overwrap 30 as is shown in FIG. 4.
  • Folding the reentrant portion 34 into the cavity 31 forms an opening end 28 of the tampon of FIG. 4.
  • the absorbent body 31 is enclosed by the overwrap 30; when the reentrant portion 34 is unfolded as in FIG. 3, a means of egress is provided by the opened end. It is desirable that the reentrant portion extend to at least approximately the midpoint of the device.
  • the opening end 28 of the tampon of FIG. 4 has no 7 proclivity toward opening before emersion in a water bath due to the fact that the overwrap itself is flexible and does not tend to spring back and the forces exerted on the tampon before and during use are primarily radially inward.
  • the reentrant portion 34 works outwardly, thereby providing the means of egress, so that the pieces 22 of absorptive material are free to exit the overwrap.
  • any of the embodiments of this invention are enhanced by a swirling or agitated water bath and it is thought to occur because the pieces 22 move with the water currents and/or have inertial forces which create forces within the overwrap tending to open the overwrap and remove the pieces 22.
  • an adhesive such as water frangible adhesive 25 of FIG. 1 can be used, if desired, to assist in closing the terminal end 36.
  • a glued closure at the terminal end 36 would be reassuring to an inquisitive comsumer examining the tampon in that the consumer would note that the agglomerate of pieces 22 is encased during use by a sealed overwrap.
  • FIG. 5 Another embodiment of a closure which will open to form a'means of egress is shown in FIG. 5 wherein the overwrap 30 is long enough such that the leading end, i.e., terminal end 37 of the overwrap 30 is adjacent the closed end 29, i.e., the reentrant portion 35 extends through the agglomerate of pieces 22.
  • the terminal end 37 can be either glued or unglued. If glued, a water frangible adhesive 33, similar to the water frangible adhesive 25 of the embodiment in FIG. 1, can be used. Also, terminal end 37 can be, but need not be, attached to closed end 29. If the terminal end 37 is attached to the closed end 29, a water frangible adhesive 33 may be used.
  • the tampon of FIG. 5 thus is a completely encased hydrodissociative agglomerate tampon having an opening end 28 which provides a means of egress.
  • both ends, rather than only one end, of the overwrap can be reentrant on the absorptive body 21 with the terminal ends of the reentrant portions being adjacent at the approximate midpoint of the tampon.
  • the terminal ends may be, but need not necessarily be, glued with a water frangible adhesive and each provides a means of egress from the overwrap.
  • the adjacent terminal ends of the two reentrant overwrap portions may, if desired, be attached to each other with a water frangible adhesive.
  • FIG. 1 An alternative tampon structure to that shown in FIG. 1 which would provide a means of egress for the pieces of absorptive material is one wherein the overwrap is essentially tubular with closed ends and has a water frangible longitudinal seam, such as seam 26 of FIG. 1 or seam 32 of FIG. 4, which opens upon exposure to an excess of water.
  • This seam can be of any of the well known types, such as one wherein the opposite edges forming the seam are overlapped and glued together with a water frangible adhesive 27, see FIG. 1, which will release when the tampon is flushed or dunked in a water closed.
  • the means of egress is the water frangible longitudinal seam.
  • the water frangible longitudinal seam can, of course, be combined with the other described means of egress to enhance the opening capabilities of the overwrap.
  • the opening capabilities are enhanced by including such a seam in the structure of the overwrap because both the longitudinal seam and the end open to thereby allow the pieces 22 forming the absorbent body 21 to escape radially as well as longitudinally from the overwrap.
  • the overwrap is a nonwoven fabric
  • the absorbent body is an agglomerate of individual and separable pieces 22 of a hydrophilic, wet swellable, polyurethane foam
  • the water frangible adhesive is one having an inverse temperature-water solubility relationship.
  • tampon can have an outside diameter of approximately 2 Va inches and a length of about 2 A inches.
  • the form forming the absorbent body weighs about 2.5 grams and is cut into pieces which are about three-eighths inch across and smaller, i.e., pieces which will pass through a screen having a three-eighths inch mesh. Although the three-eighths inch and smaller size pieces have been found to work well, the size of the pieces can vary widely. The smallest acceptable size is determined by whether the piece will absorb and whether it will be retained by the overwrap. The largest acceptable size is determined by whether the piece will be disgorged from the overwrap and whether it will pass through a sewage system.
  • the agglomerate of pieces 22 need not be coherent in and by itself because the overwrap will maintain the agglomerate, but it is contemplated that a water frangible cohesion between adjacent pieces can be used if desired.
  • This preferred embodiment can be inserted into a vagina via a telescoping tube type inserter, as is well known to those of ordinary skill in the tampon art.
  • the tampon is resiliently compressed and maintained in that condition before and during insertion by placing it in the outer tube of the inserter.
  • the outer tube is inserted into the vagina and the tampon is ejected from the outer tube by pushing the inner tube so that it telescopes within the outer tube.
  • the inserter is removed from the vagina after the tampon has been ejected from the outer tube.
  • Absorptive materials which work well as the absorbent body for the tampon of this invention are polyurethane foams described in detail in the commonly owned, copending U.S. patent application entitled Compliant Conformable Tampon, Ser. No. 172,694, filed Aug. 18, 1971.
  • One of those polyurethane foams is available commercially as Scott Hydro-Foam from Scott Paper Company, Foam Division, Eddystone, ?ennsylvania.
  • the Hydro-Foam is hydrophilic and wet swelling.
  • the material used as the overwrap is a smooth, soft, non-pilling, flexible, fluid-permeable non-woven fabric.
  • a biodegradable material for the overwrap is desirable.
  • Two non-Wovens which have functioned well as the overwrap and are believed to be biodegradable are: Dexter 2149, a non-woven fabric consisting of approximately a 60:40 cottonzrayon blend, saturation bonded with a mixture of HA8 and HA24, Rohm and Hess acrylic binders, said fabric having a measured weight of about 0.6 to 0.7 ounce per square yard and being hydrophobic and available from C. H.
  • the water frangible adhesive which can be used in the preferred embodiment of the tampon of this invention preferably has an inverse temperature-water solubility property, that is, it is insoluble at temperatures above a threshold temperature but is soluble at temperatures below that theshold.
  • Any such physiologically safe adhesive having a threshold temperature lower than normal body temperature and higher than the sewage water temperture would work satisfactorily, but preferably the threshold temperature should be between about 95F. and 70F. in a satisfactory specific application of the present invention the adhesive used had a threshold temperature of about 85F.
  • the adhesive used was Klucel and is available from Hercules, lnc., Wilmington, Delaware. Klucel is a non-ionic, water soluble, thermoplastic cellulosic material formed by reacting alkali cellulose with propylene oxide to give hydroxypropylcellulose (ether link) and having a molecular weight of about 60,000 to 1,000,000. Below is an idealized structure of a hydroxypropylcellulose molegule with a molar substitution of 3.0.
  • Elvanol is generally used with a plasticizer such as glycerin to give it a low solution viscosity.
  • Carbowax is an ethylene oxide polymer (called polyethylene rq llhalias a ria e! reams a ql gwss...
  • Carbowax 1000 to Carbowax 6000 are waxy water soluble solids suitable for some hot metal applications.
  • a material which has worked well as a withdrawal string is a waterproof cotton string having a 5/3 ply and a 9 pound tensile strength.
  • a waterproof cotton string having a 5/3 ply and a 9 pound tensile strength.
  • Such a string is available from Bibb Manufacturing Company, Macon, Georgia under the name of 5/3 ply Sno-Spun bleach 108 cotton.
  • the waterproofing on the string is to prevent wicking within the string which could lead menses outside the vagina and soil the users clothing.
  • a catamenial device comprising an absorbent body, said body being an agglomerate of discrete pieces of three-dimensional cellular absorptive material, a flexible, fluid-permeable overwrap encasing said body, and means of egress in said overwrap for said pieces, said means being discrete and localized in the overwrap, said means being substantially closed to the passage of the pieces before and during use and said means being water frangible upon disposal in a water bath, whereby said pieces remain encased before and during use and, upon disposal of the device in a water closet, an opening forms in the overwrap and the pieces disgorge through the opening and separate from the overwrap.
  • said overwrap is tubular and said closure also comprises a longitudinal seam extending to the gathered longitudinal end, the seam being secured by a water frangible adhesive, whereby when the device is placed in a water bath, said overwrap opens both along the saem and at the gathered longitudinal end to disgorge the pieces of absorptive material.
  • a catamenial device comprising an absorbent body, said body being an agglomerate of pieces of three-dimensional cellular absorptive material, a flexible, fluid-permeable overwrap encasing said body, and means of egress in said overwrap for said pieces, said means being a reentrant portion of the overwrap, said reentrant portion being an end portion of the overwrap turned inwardly around the end of and through the agglomerate of pieces, said agglomerate in the region of the reentrant portion being between the outer portion of the overwrap and the reentrant portion, said reentrant portion extending at least to about the midpoint of the device, whereby before and during use of said device said pieces remain encased by said overwrap an upon deposition of said device in a water bath said reentrant portion opens outwardly and said pieces can exit and be separated from the overwrap.
