Definitions

  • Witte ABSTRACT A side flap attached to the lateral edge of a disposable diaper such that the distal edge of the side flap overlies but is not attached to the absorbent body (except at the ends of the side flap) and the distal edge of the side flap is shorter than the straight line drawn on the absorbent pad between the points, of attachment at each end of the distal edge of the side flap such that a line of restraint is set up in each side flap when the diaper is opened and the side flap tends to be spaced from the top surface of the absorbent pad to provide an increased measure of protection against leg leakage by preventing free fluid from passing between the absorbent pad and the infants leg along each lateral edge of a disposable diaper.
  • Disposable diapers heretofore have been made both with and without side flaps.
  • Disposable diapers without side flaps have no means (1) to prevent wicking from an edge of the diaper to adjacent clothing or (2) to prevent free fluids, i.e., fluids between the infants skin and the absorbent pad such that they are not held within the absorbent pad, from bypassing between the absorbent pad and an infants leg to adjacent clothing.
  • Reusable cloth diapers which incorporate outwardly extending portions; said portions can be drawn tight about the babys thigh, e.g., U.S. Pat. Nos. 3,417,751, issued to l. L. Murdoch on Dec. 24, 1968; 2,969,065, issued to D. A. Farnsworth on Jan. 24, l96l; and 2,827,052, issued to M. Goodman et al. on Mar. 18, 1958.
  • the outwardly extending portions on these diapers are secured around a babys thigh.
  • these portions are not inwardly directed, water impervious, or a structure on a disposable diaper, and thus they do not solve the problems of bypass and wicking in a disposable diaper.
  • an improvement for a disposable diaper having an absorbent pad, a moisture impervious back sheet underlying the absorbent pad, and an inwardly disposed moisture repellent side flap overlying each lateral marginal area of the top surface of the absorbent pad, wherein the improvement comprises: each side flap being attached to the absorbent pad along a line of attachment and the line of attachment being adjacent the lateral edge of the absorbent pad whereby the distal edge of the side flap is free of attachment to the absorbent pad, the length of the distal edge of the side flap being shorter than the length of the projection of that distal edge as it is projected onto the top surface of the absorbent pad when the absorbent pad is in an endsupported flattened condition, whereby a line of restraint is set up in each side flap in an end-supported flattened condition so that each side flap tends to be spaced from the top surface of the absorbent pad.

  • FIG. 10 illustrates in cross section the diaper of FIG. 5 when worn by a baby.
  • FIG. 1 there is shown a plan view of a disposable diaper of this invention before the side flaps are shortened.
  • the diaper as shown in FIG. 1 can be formed in accordance with the teachings of U.S. Pat. No. Re26,l5 l, issued to R. C. Duncan et al. on Jan. 31,
  • the diaper has an absorbent pad 24 backed by a moisture impervious back sheet 23.
  • Absorbent pad 24 can have an absorbent body 21 superposed by a top sheet 22, the top sheet 22 providing a barrier between the absorbent body 21 and a baby's skin.
  • Back sheet 23 is larger, at least in width, than the absorbent pad 24 to provide side flaps 25 which are folded over and onto the top surface of the absorbent pad 24 whereby the side flaps 25 overlie the lateral marginal area of the top surface of the absorbent pad 24.
  • the absorbent pad 24 is attached to the back sheet 23 by a line of attachment 29 .between the bottom surface of the absorbent pad 24 and the back sheet 23 adjacent to each lateral edge of the diaper.
  • the line of attachment 29 in this embodiment extends along and substantially parallel to the lateral edges of the diaper.
  • the side flap 25 on each side of the diaper thus is attached along a line of attachment 29 to the lateral edge of the absorbent pad 24 and that portion of the side flaps 25 lying inwardly from the extreme side edge of the absorbent pad is free of attachment to the absorbent pad 24.
  • side flap 25 has a distal edge 30 which lies inwardly from the edge of the absorbent pad 24 and is essentially free of attachment to absorbent pad 24.
  • each end, i.e., both the anterior and posterior ends, of the distal edge 30 are attached to the top surface of absorbent pad 24 by a flap-end adhesive means 32, but the advantages of this invention can also be realized if the flap-end adhesive means 32 is eliminated from the diaper.
  • the side flap 25 should have a minimum width of about three-eighths inch and preferably about threefourths inch. The minimum width is necessary to achieve an effective shortened side flap.
  • the line of attachment 29 alternatively can be between the contacting surfaces of the side flap 25 and the top surface of the absorbent pad 24 along the side edge 33 of the absorbent pad 24 as is shown in FIG. 2.
  • the back sheet 23 preferably is a flexible waterproof web, e.g., a 0.001 inch thick, low density, pattern embossed, opaque polyethylene web.
  • the diaper of FIG. 1 is folded to the configuration of FIG. 2 along infold lines 26, outfold lines 27, and infold line 46.
  • Infold is used herein to denote that the top surface areas of the absorbent pad 24 lying on either side of the fold line are brought together and put in surface contact when the fold is made.
  • Outfold is used herein to denote that the surface areas of the back sheet 23 lying on either side of the fold line are brought together and put in surface contact when the fold is made.
  • lnfolds 26 and outfolds 27 are made prior to infold 46.
  • fold maintaining glue spots 28 maintain the infold 26 at the longitudinal center of the pad so that the Z-fold configuration is maintained in the crotch area of the diaper while the diaper is being worn.
  • the diaper of FIG. 2 is shown in an end-supported flattened condition, i.e., the center fold 46 is allowed to unfold and the ends of the diaper are supported by the shortened side flap 25.
  • Side flap 25 is shortened to the extent that the length of the distal edge 30 of the side flap is shorter than the projection 38 of the distal edge 30 onto the top surface of the absorbent pad 24 immediately below it.
  • the distal edge 30 is shorter than the length of the absorbent pad immediately beneath the distal edge 30 and thus a line of restraint is set up in each side flap 25 supporting the ends of the diaper when the center fold 46 is unfolded.
  • FIG. 7 shows in detail for another embodiment a separately formed side flap attached to the back sheet.
  • the side flap 25 can be shortened for a diaper of the embodiment shown in FIG. 2 by making the distal edge 30 shorter than the length of the side flap 25 along the line of attachment 29. This shortening can be effected by putting a triangular pleat 47 in the side flap 25 whereby the distal edge 30 is shortened more than the the side flap edge adjacent the side edge 33 of the absorbent pad 24 (hereinafter referred to as the proximal edge of the side flap 25).
  • the pleat 47 is then secured by any of the holding means well known to those of ordinary skill in the art, such as adhesives or heat sealing.
  • the triangular section could also be cut out of the side flap 25 and the cut edges of the side flaps brought together to form a butt or lap joint.
  • the side flap 25 can also be shortened by shrinking the distal edge 30 thereof.
  • This shrinking can be accomplished, for example, on a polyethylene film, by heating the distal edge 30.
  • Polyethylene film is stressed along its length during its processing. Heating the stressed polyethylene will release the internal stresses therein and promote a reduction in length along the heated area. It has been found that heating the distal edge 30 with an element at 230 F. for periods of time short enough such that the polyethylene does not melt is sufficient to cause a shortening of the distal edge 30.
  • the side flap 25 can also be effectively shortened by attaching a point near each end of the distal edge 30 to the absorbent pad 24 at a position inwardly from the position of each point on the absorbent pad when the side flaps are not shortened. This in effect makes the distal edge 30 shorter than the length of the absorbent pad underlying the distal edge 30.
  • the shortening of the side flap 25 is preferably uniformly distributed along the length of the side flap such as is done when a stressed polyethylene side flap is heated to relieve internal stresses.
  • a uniform distribution of the shortening in the side flap 15 is advantageous because each increment of length of the side flap 25 is shortened a proportional amount of the overall shortening and undue distortion of the side flap 25 in any one area is avoided.
  • the distal edge 30 of the side flap 25 should be from about 2 percent to about 10 percent shorter than the proximal edge of the side flap 25 along the effective length of the side flap, preferably from about 4 percent to about 10 percent.
  • the effective length of the side flap varies in accordance with the specific embodiment. For example, if the ends of the distal edge 30 are attached to the top surface of absorbent pad 24 by the flap-end adhesive means 32 as shown in FIG.
  • the effective length of the side flap 25 is the length of the side flap 25 between the flap-end adhesive means 32 at the opposite ends, i.e., the anterior and posterior ends, of the side flap 25; whereas if the flap-end adhesive means 32 is not used, whereby the ends of the distal edge 30 are free of attachment to the top surface of the absorbent pad 24, the effective length of the side flap 25 is the .actual length thereof.
  • the distal edge 30 should be. a minimum of about 2 percent shorter in order to achieve some spacing of the distal edge 30 from the top surface of the absorbent pad .24.
  • the maximum of about, percent shortening is desired to insure that the shortened side flap is inwardly directed as shown in FIG 3, or in other words, to prevent the side flap 25 from forming an obtuse angle with the top surface of the absorbent pad 24 when the diaper is in its end supported position.
  • the cross section in FIG. 3 displays more vividly the effect of the shortened side flaps wherein the distal end is spaced from the top sheet 22 to provide a constraining dam for free fluid flowing along top sheet 22.
  • Free fluid on the top sheet 22 is most probable when the top sheet 22 has a poor strikethrough? property, i.e., when fluid penetration of the top sheet 22 is retarded.
  • the dam created by the distal edge 30 being spaced from the top sheet 22 is also advantageous when the top sheet 22 has good strikethrough because the side flap will prevent bypass of gushing fluids which can occur at thetime a baby urinates.
  • the 'damming effect createdby a shortened side flap has been found advantageous in diapers wherein the strikethrough of the top sheet 22, as measured by percent of water which runs off a sheetinclined 5, is as low as zero percent.
  • the runoff test as used to measure strikethrough comprises clamping a preweighed sample consisting of the fabric to be tested backed by a suitable absorbing medium, e.g., cellulose wadding or airfelt, on a flat sheet, e.g., plexiglass or metal; positioning the sheet at some desired inclination angle to the horizon; metering a 50 milliliter quantity of water, which weighs about 48 grams, onto the sampleat a spot 9 inches from the lower edge of the sample at a rate of approximately 5 milliliters per second; and weighing the wetted sample and deducting the tare of the sample to determine the approximate weight of water absorbed by the sample.
  • the percent runoff is then determined as follows:
  • Percent runoff I Olet al.
  • a strikethrough stated as a low percent indicates rapid penetration of the sheet by the water whereas a'strikethrough stated as a high percent indicates a slow penetration of the sheet by the water.
  • top sheets Two types of top sheets, i.e., a "standard” and a quick strikethrough (08) top sheet, were used in diapers having shortened side flaps and improved containment as measured by leg leakage of the diapers was achieved with both of the top sheets as compared to similar diapers with the same top sheet but not having the shortened side flaps.
  • the standard top sheet was a print bonded rayon non-woven fabric having a basis weight of 18 to 19 grams per square yard.
  • the rayon used was 1% denier, 1% inch. staple in the formof a carded web.
  • the bonding agent used was Rohm and Haas Rhoplex, PIA-8.
  • the standard top sheet is available from Kendall Co., Fiber Products Division, Walpole, Mass.
  • the runoff of water for the standard top sheet I was 30 percent when the sheet was inclined 5 and 75 percent when the sheet was inclined 20.
  • the 08 top sheet was the same as the standard except that a different bonding agent, which is not known to applicants at this time, was used.
  • the 08 top sheet is also available from Kendall Co. and is identified by Kendall Co. as SW 269-3.
  • the runoff of water for the Q8 top sheet was zero percent when the sheet was inclined 5 and 3.0 percent when the sheet was inclined 20.

  • outer infolds 63 and 64 extend to the end points 65 and 66, respectively, from the intermediate points 61 and 62, respectively.
  • Posterior joinder points 51 and 51 and anterior joinder points 52 and 52 are provided as convergence points for additional infolds and outfolds along the side edges of the diaper preferably so that each joinder point is further from the central fold 71 than it is from its nearest anterioror posterior end 34 or 35.
  • Each of the joinder points 51, 511, 52 and 52' preferably lies at about the same distance from the central fold 71. Extending from the joinder points are theinfolds 26.
  • the pair of infolds 26 on the left side of the diaper merge at the inner point 58 and the pair of infolds in the right side of the diaper merge at the inner point 57.

  • the diaper of FIG. 4 is readily folded on itself during which manipulation it passes through the configuration illustrated in FIG. 5. This is accomplished by merely bringing the ends of the pad 34 and 35 together so that the central infold 56 in effect functions as a hinge point.
  • the inner triangular areas 67 fold inwardly (see FIG. 2) against the areas of the top surface of the absorbent pad 49 which adjoin the infolds 26.
  • the outer triangular areas 68 formed on either side of the outer infolds 63 and 64 fold together in pairs as a result of the outfolds 27.
