Definitions

  • This invention relates to a fiushable sanitary napkin as hereinafter defined and more particularly to a flushable sanitary napkin having a reinforcing and securing strip between the overlapping edges of a fiushable wrapper of creped cellulosic fibrous sheet material for securing the overlapping edges of the wrapper together.
  • the reinforcing and securing strip is adapted to restrict elongation of the creped wrapper, provide additional strength to the wrapper, and to form and hold the body contacting face of the sanitary napkin in a relatively smooth longitudinally curved configuration conforming generally to the natural body contour of the wearenwhen placed in position thereon to provide a greater surface area in contact therewith for optimum absorbence and comfort.
  • the sanitary napkins of the present invention are constructed with a flushahle wrapper of creped cellulosic fibrous sheet material disposed around and enclosing an interior pad of dispersible absorbent material and defining overlapping edges.
  • This reinforcing and securing strip must be relatively inextensible under the normal forces placed thereon when worn in position on the wearer and it is noted that this feature would not be necessary in the glue lines, selfadhesive filaments, threads or filaments coated with adhesive, etc. utilized as a securing means in the prior more conventional sanitary napkins.
  • the flat, ribbon-like configuration of the strip has been found important to pro vide a sufiieiently larger surface area for gripping the overlapping edges of the wrapper than would be provided with a thin, curved, string-like, or otherwise configurated strip.
  • this reinforcing and securing strip is disposed between the overlapping edges of the wearer on one face of the sanitary napkin, it is preferred to utilize this face as the outer face of the napkin to be placed away from the skin of the wearer and for this purpose the strip may be colored in any suitable manner to indicate the side of the sanitary napkin to be placed away from the skin of the wearer.
  • the reinforcing and securing strip provides an additional and very important function not heretofore attained of forming and holding the interior face or the body contacting face of the sanitary napkin in a relatively smooth longitudinally curved configuration conforming to the natural body contour of the wearer to provide a greater surface area of the napkin in direct contact with the curved contour of the body of the wearer providing optimum absorbence and comfort.
  • FIGURE 1 is a reduced perspective view of a sanitary napkin having a reinforcing and securing strip according to this invention
  • FIGURE 2 is a full scale cross-sectional view of the sanitary napkin of FIGURE 1 taken substantially along the line 2-2 of FIGURE 1;
  • FIGURE 3 is a reduced perspective view of the sanitary napkin of FIGURE 1 showing the same in a relatively smooth longitudinally curved configuration conforming generally to the natural body contour of the wearer;
  • FIGURE 4 is a full scale cross-sectional view of the sanitary napkin of FIGURE 3 taken substantially along the line 4-4 of FIGURE 3.
  • sanitary napkin generally indicated by the reference numeral 10, constructed according to this invention.
  • the sanitary napkin 10 comprises an interior pad 11 of desirable fibrous absorbent material adapted to absorb body fluids.
  • This interior pad 11 may be layered, cut, folded or otherwise formed to provide this function.
  • this interior pad 11 is formed from a cut, fluifed, fibrous wood pulp batt 14 having a cut layer of creped tissue paper 15 superimposed thereon.
  • the batt 14 and the creped tissue paper layer 15 are folded with a multiple reverse fold extending in the longitudinal direction of the pad to form a multi-layer interior pad 11, as shown in FIGURE 2.
  • the interior pad 11 may also include a conventional moisture barrier 16 formed of any suitable liquid impervious material and disposed between the folded over layers, as illustrated in FIGURE 2.
  • the sanitary napkin 10 further comprises a flushable, fluid permeable wrapper 20 of creped cellulosic fibrous sheet material disposed around and enclosing the interior pad 11 and defining longitudinally extending overlapping edges 22.
  • the wrapper material comprises bonded, hydrophilic, flat, ribbon-like, aerated, regenerated cellulose fibers of the generally collapsed, multi-cellular form to provide high dry strength, wet hang and dispersibility for the wrapper when agitated in a large excess of water to render the same completely flushable in an ordinary Water closet.
  • An improved form of this wrapper material is disclosed and claimed in copending application, Ser. No. 572,929, filed Aug. 17, 1966, noW U.S. Patent No. 3,370,590 and assigned to the assignee of the present invention and reference may be had thereto for further details of this material.
  • the sanitary napkin further comprises a reinforcing and securing strip 30 disposed between the overlapping edges 22 of the wrapper and, preferably, extending between these overlapping edges along the entire longitudinal dimension of the sanitary napkin 10.
  • the reinforcing and securing strip comprises a generally inextensible, thin, fiat, ribbon-like strip coated with an adhesive for securing the overlapping edges of the wrapper together.
  • This strip may be constructed of any suitable relatively inextensible material, such as a woven textile material, an extruded plastic filament (nylon, polyester, etc.), or any other suitable material which will provide the desired inextensible and strength features to restrict the normal tendencies of the creped wrapper material to elongate and the inherent weakness therein.
  • the strip may be coated with any type of suitable adhesive, such as a hot melt glue or the like, for securing the overlapping edges of the wrapper material together.
  • This reinforcing and securing strip provides an additional feature, which is illustrated in FIGURES 3 and 4, of forming and holding the interior face or the body contacting face, generally indicated by the reference numeral 35, of the sanitary napkin in a relatively smooth longitudinally curved configuration conforming to the natural body contour of the wearer to provide a greater surface area of the napkin in direct contact with the curved contour of the body of the wearer providing optimum absorbence and comfort.
  • This longitudinally curved configuration is accomplished when the napkin is pulled into a generally curved configuration around the body of the wearer since there will be greater forces applied to the outer face of the napkin than will be applied to the inner face of the napkin and since the reinforcing and securing strip is located on the outer face of the napkin to render the same substantially inextensible. These forces will be applied on the outer face along a longitudinal center line conforming to the position of the reinforcing strip such that this portion of the sanitary napkin will be pushed inwardly to in turn form a longitudinall curved configuration on the inner face of the napkin which will more nearly conform to the natural curved contour of the body of the wearer. In this manner, there will be more surface area on the interior 5 face of the sanitary napkin in contact with the curved natural body contour of the wearer providing optimum absorbence and comfort to the wearer.
  • a flushable sanitary napkin comprising:
  • a reinforcing and securing strip disposed between said overlapping edges of said wrapper and comprising a generally inextensible, thin, flat, ribbon-like strip coated with an adhesive for securing said overlapping edges of said wrapper together, said strip being adapted to restrict elongation of said creped wrapper, provide additional strength to said wrapper, and form and hold the body contacting face of said sanitary napkin in a relatively smooth longitudinally curved configuration conforming generally to the natural body contour of the wearer when placed in position thereon to provide a greater surface area in contact therewith for optimum absorbence and comfort.
  • a flushable sanitary napkin as set forth in claim 1, in which said reinforcing and securing strip comprises a plastic strip coated with a hot melt glue.
  • a flushable sanitary napkin as set forth in claim 1, in which said reinforcing and securing strip extends between said overlapping edges along the entire longitudinal dimension of said sanitary napkin.
  • a flushable sanitary napkin as set forth in claim 1, in which said reinforcing strip is colored to indicate to the wearer the side of the napkin to be placed away from the body when worn.
