Definitions

  • Sheets-Shet 2 1 PREFOLDED DISPOSABLE DIAPER BACKGROUND OF THE INVENTION Disposable diapers being sold to the consumer are prefolded in a number of ways in an attempt to provide the user with a style which readily fits around the child, especially in the interior leg area, to ward off leakage while maintaining a centrally depending pocket to entrap excrement.
  • the most sophisticated of these folded styles enable the mother to obtain a neat close fit merely by positioning the diaper in place on the child.
  • the prior art folds are not all directly parallel to, or perpendicular to, the length of the diaper, complex mechanical motions are required to obtain the folds and it is therefore necessary to design elaborate and costly machinery to mass produce such diapers.
  • Exemplary of one such style is the diaper shown in I-Irubecky US. Pat. No. 3,196,874 in which a set of complicated infolds and outfolds provide a substantially triangular-shaped contoured diaper with a centrally disposed pocket and leg-hugging side portions. It would be desirable to be able to make a somewhat similarly contoured diaper with less complicated folds, and yet provide many of the advantages obtained by the more sophisticated style of the prior art diapers mentioned.
  • the present invention is directed toward such a diaper, having a very simple fold construction which automatically provides a centrally disposed pocket, and which requires only a minor rearrangement of the side edges by the user to provide a good leg-hugging contour when applied to the child.
  • the rectangular diaper is folded in half transversely across its major length dimension with the pervious facing sheet on the inside. Portions of the diaper located on each side of the mid-point of the transverse fold line are tucked into the interior of the diaper by means of inward folds away from the transverse fold line to form a substantially triangular pocket centrally disposed within the folded diaper. This provides a pair of adjacent interior folds and four diagonal exterior folds.
  • the external edges of the exterior fold, the internal edges of the interior folds and the side edges of the diaper which are tucked in thus form the sides of four matched triangular panels having their surfaces in face-to-face association.
  • Interior surface areas of the triangular panels defined by the edges of these interior and exterior folds of the infolded portions are fastened to surface areas of adjacent panels and serve to maintain the prefolded contour of the triangular shaped central pocket after the diaper is partially unfolded for use.
  • the outer sides of the diaper terminating at the top of the pocket are preferably first folded downward by the user in order to provide a better leg fit at the diaper sides.
  • FIG. 3 is a perspective view of the diaper of FIG. 1 showing the diaper partially folded along the dotted lines shown in FIG. 1.
  • FIG. 4 is a plan view of the completely folded diaper of FIG. 3.
  • FIG. 4a is a stylized section taken along line 4a4a of FIG. 4.
  • FIG. 5 is a plan view of a modified diversion of a completely folded diaper.
  • FIG. 2 illustrates in partial section a conventional internal construction with impervious film 23 wrapped around the edge of pad 21 and sealed to the bottom edge of fluid-permeable cover sheet 22.
  • broken lines 10a, 10b, 14a, 14b; and 15a, 15b represent lines along which the diaper is folded and which divide the diaper into substantially triangular segments designated as panels A through F.
  • FIG. 3 the inward and outward fold direction along these lines is demonstrated.
  • the folds defined by the transverse middle line are comprised of segments 10a and 10b. It will be seen that the diaper is tucked directly inwardly along these segments from each side of mid-point 18. As shown in this partially folded view,
  • the fold along line segment a by the inward tuck on the right side extends from central point 18 to point 16.
  • the fold along line segment 10b by the inward tuck on the left side extends from central point 18 to point 17.
  • the inward tuck provides outwardly disposed folds along diagonal line segments 14a and 15a on the right side, and diagonal line segments 14b and 15b on the left side.
  • FIG. 4 a plan view of the completely folded diaper of FIGS. 1-3 is shown.
  • a plurality of glue spots 30, or other joining means are interposed between facing surfaces of the impervious backing sheet portion of triangular panels C & E, and D & F, as more clearly shown in the stylized sectional view of FIG. 4a.
  • Joining portions of the contacting panel surfaces together stabilizes the pocket 18 formed by the folds, and maintains joined areas of the folds in positive association so that when the diaper is partially unfolded or opened for application to the child, the pocket configuration is held intact.
  • the joined areas be disposed approximately halfway between the diaper ends and the transverse fold line.
  • FIG. 6 a transverse section of a modified form of the absorbent pad structure in flat, unfolded form is shown.
  • absorbent pad 21a disposed between cover 220 andbacking sheet 23a, is thin at the longitudinal side areas 40 and 42 and thick at the longitudinal center area 43.
  • This structure of the absorbent pads avoids excessive bulkiness along areas adjacent the sides and permits the sides to be turned down more easily when the diaper is applied to the child by the user.
  • This sectional profile of the absorbent pad is readily adaptable to each of the fold modifications described.
  • attachment means 30 and 35 are shown as round spots of adhesive or the like, it will be seen that the form of attachment can be in the shape of squares, diamonds, lines, or the like as long as they are appropriately placed where indicated.
  • attachment means is disposed between contacting faces of the film backing sheet and this is the preferred embodiment.
