  • a sanitary napkin to be worn in the crotch portion of an undergarment.
  • the napkin comprises a garment contacting surface, a body contacting surface and an absorbent element therebetween.
  • the garment contacting surface has a layer of material thereon having a high co-efflcient of friction such as, for example, a layer of cellular foam.
  • a second layer comprising a pressure sensitive adhesive.
  • an attachment system provided in accordance with the teachings of this invention, exhibits a resistance far greater than the combined sum of a frictional system and an adhesive system each taken alone.
  • a resistance to displacement results which exceeds the sum of the measured resistances for the frictional system and the prior adhesive attachment system when each is operating alone.
  • FIG. 1 is a perspective view of a full sized sanitary napkin embodying the teachings of this invention and illustrated with its protective cover partially peeled off;
  • FIG. 2 is a cross sectional view of the napkin illustrated in FIG. I and taken through line 2-2 of FIG. 1;
  • FIG. 3 is a perspective view of a minipad also embodying the teachings of this invention.
  • FIG. 4 is a cross sectional view of the minipad of FIG. 3 taken through line 44.
  • FIGS. I and 2 of the drawings illustrated therein in perspective and cross sectional views, respectively, is a full size sanitary napkin l0 embodying the teachings of this invention and shown with the surface normally worn away from the body facing upwardly.
  • the napkin consists of an absorbent element 12 which is shown in the form of a generally rectangular pad and may consist of loosely associated absorbent material such as; cellulosic fibers, for example, wood pulp, regenerated cellulose or cotton fibers; other chemically or physically modified cellulose fibers; other polymeric absorbent materials, both natural and synthetic, such as hydrophilic foams (e.g.
  • hydrophilic polyurethane foam may be such commonly used absorbent material as wadded tissue paper or the like.
  • the absorbent element 12 may be a shaped form such as molded hydrophilic polymer (eg. a molded hydrophilic polyurethane foam or a molded cellulosic form), or any combination of these absorbent materials.
  • the absorbent element 12 is wrapped in a fluid pervious sheet material 14 which overlies the garment contacting surface of the napkin (i.e. that surface normally worn away from the body) and the body contacting surface of the napkin (ie that surface normally worn against the body) as well as the sides of the napkin.
  • the sheet material may be of rectangular shape and somewhat wider and longer than the absorbent element so that it can be sealed by overlapping the longitudinal edges 16 and 18 of the sheet on the garment contacting surface and sealing them together in the area of overlap with a suitable adhesive 20.
  • the ends 22, 24 of the sheet may also be sealed or crimped together thereby fully enclosing the absorbent element.
  • the sheet material may be any woven or nonwoven ma terial pervious to fluid striking its surface, such sheets being well known in the art in connection with sanitary napkins.
  • a frictional layer 26 of material having a high co-efficient of friction is provided on the garment contacting surface of the napkin and as shown in FIGS. 1 and 2, overlies a portion of the sheet material 14.
  • the frictional layer overlies the major portion of the sheet on the garment contacting surface.
  • the frictional layer may be secured to the garment contacting layer by any of the methods known in the art, such as with a suitable adhesive, with heat sealing, or may be extruded thereon.

  • the pressure sensitive adhesive layer is in the form of an elongated rectangular strip longitudinally extending on the friction layer 26.
  • a peelable protective cover 30 is provided which may be removed just prior to use, and is shown partially peeled from the napkin.
  • the protective cover 30 is peeled from the napkin exposing the pressure sensitive adhesive.
  • the napkin is then pressed into position in the crotch of an undergarment and, because of the unique combination of frictional and adhesive layers taught herein, the napkin will resist repositioning to a remarkable and totally unexpected extent. Notwithstanding the strong tendency to remain in place when worn, the napkin easily peels from the crotch portion of the undergarment when the user is disposing of the same.
  • the napkin of this invention peels with no more effort than these prior napkins and with less tendency to leave undesirable adhesive residue deposited on the undergarment and less tendency to tear the napkin upon separation from the garment.
  • a minipad 32 embodying the teachings of this invention, the minipad being shown with thle garment contacting surface facing upwardly.
  • the minipad 32 a smaller, thinner version of the full size sanitary napkin, consists of a relatively thin, flat, generally rectangular, absorbent element 34 which may be comprised pf the same kind of absorbent materials as described abpve in connection with the full size napkin of FIGS. 1 a d 2.
  • a fluid pervious sheet 36 envelopes the body con acting surface, the sides and a portion of both longitu 'nal margins of the garment contacting surface of the ab rbent element.
  • this sheet may be of the same ty H e as that used in connection with the above described ftill size napkin.
  • a fluid impervious layer 38 Overlying the garment contacting surface of the element 34 and marginal portion of the sheet 36, is a fluid impervious layer 38 provided to preclude fluid from passing onto an undergarment and which may be any thin flexible impervious layer, for example a polymeric film such as polyethylene or polypropylene film, cellophane, or a generally fluid pervious material that has been treated to be impervious such as impregnated, fluid repellent paper.
  • Adhesive may be applied to the surface of the imper vious layer 38 which faces the absorbent element 34 and will permeate through the portions of the pervious layer 36 on the garment contacting surface of the element 34, securing both the pervious and impervious layers to the element 34.
  • the ends of the minipad may be secured by adhering the pervious and impervious layers together where they extend beyond the ends of the absorbent element 34.
  • a frictional layer 40 is provided overlying the major por tion of the fluid impervious layer on the garment contacting surface of the minipad, this frictional layer 40 having a high coefficient of friction and adhered to the minipad by the means described above, e.g., with heat sealing adhesives, or extrusion.
  • Overlying a portion of the frictional layer 40 are, in this specific embodiment, two generally square-shaped pressure sensitive adhesive layers 42 protected by peelable protective covers 44.
  • the protective covers 44 may be peeled off to expose the adhesive layer 42.
  • the minipad may be pressed into the crotch of an undergarment where it will remain firmly in place yet be easily peeled off after use and discarded without the tearing of the napkin or the undergarment and without the deposition of adhesive residue.
  • the full size napkin may be provided with a fluid impervious sheet, either as an outer cover as is shown for the minipad, or as a barrier sheet disposed between the absorbent element and the pervious layer or even within the absorbent element.

  • the co-efficient of friction is defined by the lnstron Frictional Test as will be described in greater detail below but may be generally stated as the force necessary to slidably displace, on a standard surface, the surface being tested divided by a force applied normal to the direction of displacement.
  • Examples of such usable frictional layer materials are those woven and nonwoven fabrics, films and sheets which meet the co-efficient of friction requirements set forth above and are not incompatible with the desired use.
  • the surface of otherwise unsuitable materials may be treated to increase their co-efficient of friction by mechanical means such as by embossing, micropleting or creping or coating or impregnating with binders, adhesives, or chemicals such as vinyl polymers e.g., ethyl vinyl acetate polymer, polystyrene; rubbers e.g., butadiene rubber, nitrile rubber, latex rubber or the like.
