ABSORBENT ARTICLE AND METHOD 7 BACKGROUND OF THE INVENTION DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 is a fragmentary front plan view of the diaper The present invention relates to absorbent articles, of the present invention;

and more particularly to disposable diapers.

In the recent past, a various assortment of disposable diapers have been proposed for use on infants. Although a number of such diapers are in everyday use, a few factors have created problems which prevent a totally satisfactory diaper. First, the shape of the infants thigh in the crotch region presents an irregular surface with which it is difficult to achieve a close fit of the diaper; second, it has been difficult to attain a proper fluid barrier to prevent diaper leakage in the crotch region; and third, it has been difficult to place sufficient absorbent material in the crotch region of the diaper, where absorbency is most needed, without adding significantly to the bulk of the diaper and resultant discomfort to the infant.

SUMMARY OF THE INVENTION A principal feature of the present invention is the provision of a diaper of simplified construction and improved fit.

The diaper of the present invention has an absorbent pad assembly having a pair of side edges, a longitudinally extending central panel, a pair of doubled longitudinally extending back panels underlying the central panel, and a pair of longitudinally extending top panels extending from the back panels and overlying the central panel. Means is provided for securing the top panels and the back panels to the central panel in the crotch region of the diaper.

A feature of the present invention is that the diaper provides a contoured fit in the crotch region.

Another feature of the invention is that the doubled back panels define pocket means for receiving and retaining fluid runoff from the central panel.

Yet another feature of the invention is that the back panels increase the amount of diaper absorbency in the crotch region without adding significantly to the bulk of the diaper.

Still another feature of the invention is that the multiple layers of the pad assembly in the crotch region provide an improved gasketing effect about the infants legs.

The diaper of the present invention has a fluid impervious backing sheet covering the outer surface of the top panels relative the central panel and at least a portion of the inner surface of the top panels intermediate the top panels and the central panel.

Thus, another feature of the present invention is that the fluid impervious outer surface of the top panels prevents leakage of the diaper in the crotch region.

Still another feature of the invention is that the top panels have a fluid impervious barrier adjacent the side edges to prevent leakage in the crotch region of the diaper.

Yet another feature of the invention is that the top panels direct fluid to the back panels for retention therein.

Still another feature of the invention is the provision of a method for making the diaper of the invention.

Further features will become more fully apparent in the following description of the embodiments of this invention and from the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to FIGS. 1 and 4, there is shown a disposable diaper generally designated 20 having an absorbent pad assembly 22. The pad assembly 22 has a pair of side edges 24a and 24b, and a pair of end edges 26a and 26b connecting the side edges 24a and b. As shown in FIG. 4, the pad assembly 22 has a fluid pervious top sheet 28 defining a substantial portion of the front surface 30 of the pad assembly, a fluid impervious backing sheet 32 defining a back surface 34 of the pad assembly, and an absorbent pad 36 positioned intermediate the top and backing sheets 28 and 32. The width of the backing sheet 32 is greater than the width of the absorbent pad 36, and end sections 38a and 38b of the backing sheet are folded over the front surface 30 of the pad assembly 22 and secured in place over the absorbent pad 36. Similarly, as shown in FIG. 1, the length of the backing sheet 32 may be greater than the length of the absorbent pad, such that end sections 40a and 40b may be folded over the front surface of the pad 36 to define fluid barriers at the longitudinal ends of the pad assembly 22.

The diaper of the present invention may be formed from the pad assembly of FIG. 4 according to a method of the invention as follows. The pad assembly is first folded along a pair of longitudinally extending fold lines 42a and 42b, as shown in FIG. 5, with the fold lines 42a and b defining a pair of side panels 44a and 44b extending between the side edges 24a and b and the first fold lines 42a and b, the side panels 44a and b being folded against the front surface 30 of the pad assembly 22. The side panels 44a and b are secured to the front surface 30 of the pad assembly 22 in the crotch region of the diaper, and in one embodiment adjacent the side edges 24a and b by suitable means 46a and 46b, such as adhesive. The securing means 46a and b is preferably offset 1-2 inches from the longitudinal mid-point of the diaper toward the end edge 26a at the front of the diaper.

Next, the folded pad assembly of FIG. 5 is folded along a second pair of longitudinally extending fold lines 48a and 48b which are intermediate the side edges 24a and b and the first fold lines 42a and b, as shown in FIG. 3, with the second fold lines 48a and b defining a pair of edge sections 50a and 50b which are folded against the back surface 34 of the pad assembly 22. The edge sections 50a and b are secured against the back surface of the pad assembly in the crotch region of the diaper by suitable means 52a and 52b, such as adhesive.

The diaper thus constructed is illustrated in FIGS. 13. As best shown in FIGS. 1 and 3, the diaper has a longitudinally extending central panel 56, and a pair of longitudinally extending top panels 54a and 54b overlying the central panel 56. The top panels 54a and b have a fluid impervious outer surface relative the central panel 56, due to their covering by the backing sheet 32, and fluid impervious inner surface portions adjacent the side edges 24a and b, due to the end sections 38a and b of the backing sheet extending past the side edges. As best shown in FIGS. 2 and 3, the diaper 20 has a pair of doubled longitudinally extending back panels 58a and 58b underlying the central panel 56. The diaper 20 may have a pair of tape strips 60a and 60b adjacent the side edges 24a and b and adjacent the end edge 26b for securing the diaper about the infant.

During placement of the diaper, the waistband portions of the diaper adjacent the end edges 26a and b are unfolded, as illustrated in FIG. 6, while the securing means 460 and b and 52a and b retains the top panels 54a and b and back panels 58a and b in place against the central panel 56. Accordingly, when the diaper is unfolded for placement, the top panels become contoured to the shape of the infants legs to provide an improved fit of the diaper in the crotch and thigh region. The backing sheet 32 provides a fluid impervious outer surface for the top panels 54a and b and a fluid barrier adjacent the side edges 24a and b to prevent leakage and wicking of the diaper in the crotch region. The doubled back panels 58a and b underlying the central panel 56 serve as pocket means to receive and retain fluid runoff from the central panel 56, while the fluid impervious top panels direct fluid to the pockets. Moreover, an increased amount of absorbent pad is provided in the crotch region of the diaper for greater fluid retention without increasing the bulk of the diaper in the crotch region, since the top and back panels are retained in place by the securing means. The four plies of the absorbent pad in the crotch region also provide greater tension of the diaper against the infants skin for a better gasketing action to prevent leakage about the infants legs.

If desired, the diaper may be folded in a slightly different manner, according to a method of the invention, as described below. First, referring to FIG. 3, the pad assembly of FIG. 4 may be folded along a pair of longitudinally extending fold lines 62a and 62b, such that the fold lines define the central panel 56 and the pair of side panels 44a and b which are folded against the back surface 34 of the central panel. The side panels are then folded along the longitudinal fold lines 42a and b intermediate the first fold lines 62a and b and the side edges 24a and b, with the fold lines 42a and b defining a pair of edge panels which are folded around the fold lines 62a and b and overlie the front surface of the central panel 56. The top panel portions 54a and b of the edge panels are secured to the front surface of the central panel 56 and the back panel portions 58a and b of the side panels are secured to the back surface of the central panel, as previously described.

Addtional embodiments of the pad assembly 22 are illustrated in FIGS. 7 and 8, in which like reference numerals designate like parts. The absorbent pad 36 in the pad assembly of FIG. 7 has a plurality of longitudinally extending embossments a, 70b, and 70c on each side of the longitudinal center line of the diaper, such that the thickness of the pad is reduced in the embossed areas. The embossments 70a, b, and c correspond with the fold lines 48a, 42a, and 62a, respectively, on one side of the diaper, as shown, and 48b, 42b, and 62b on the other side of the diaper, and facilitate folding of the pad assembly along the fold lines during manufacture due to the reduced thickness in the areas of the fold lines. Similarly the absorbent pad 36 of FIG. 8 has a plurality of spaced longitudinally extending pad segments 37a, 37b, 37c, and 37d defining separated areas 39a, 39b, and 390 on each side of the diaper in the areas of the fold lines to facilitate folding of the diaper.

In a preferred embodiment, the securing means 46a and b is spaced from the side edges 24a and b of the top panels 54a and b, as shown in FIG. 9, such that the securing means retains the end sections 38a and b of the backing sheet against the front surface of the central panel at a location spaced from the side edges 24a and b. After placement of the diaper, stress is applied to the top panels adjacent the side edges 24a and b, and the spaced securing means permits edge portions 67 of the top panels adjacent the side edges to rise from the front surface of the central panel. Thus, the edge portions 67 are positioned in the juncture of the infants crotch and thigh during use, and a fluid impervious seal is formed by the edge portions against the infants skin to prevent leakage.

Thus, there has been described a diaper which provides an improved fit in the crotch region without adding significantly to the bulk of the diaper. At the same time, the diaper minimizes fluid leakage and provides for greater fluid retention in the crotch region. Meth ods have also been described for making the diaper of the present invention from the pad assembly of FIG. 4.

The foregoing detailed description is given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, as modifications will be obvious to those skilled in the art.
