Abstract

A disposable diaper comprises an absorbent structure integrated within an outer cover. The outer cover includes front and rear elasticized waist panels, an intermediate crotch panel separating the waist panels from one another, a pair of sides extending between and interconnecting the waist panels, a pair of leg openings delimited along the sides and front and rear pairs of ears delimited at the sides of the front and rear waist panels, respectively. The rear pair of ears define elongated shapes with internal, body-facing surfaces, a proximal portion spaced from a line centered on the longitudinal axis of the diaper, suer end portions spaced distally from the proximal portions and elastomeric medial portions adjustably spacing and separating the user portions from the proximal portions. The front pair of ears have externally-facing surfaces presenting appointed landing zones, including fixed-position fasteners, cooperable with fixed fasteners provided on the user ends, and including variable-position fasteners selectably engageable with cooperating variable fasteners provided on the proximal portions, wherein the medial portions stretch to allow adjustment and fastening of the fixed-position fasteners once the variable-position fasteners have been selectably fastened.

Claims

1. An article of wear, comprising:

an elongate, outer cover including first and second end portions sized and shaped to overlie the front and rear waist areas of a person, and an intermediate portion separating said end portions from one another and sized and shaped for overlying the crotch of the person, and a pair of side portions extending between and interconnecting said end portions and laterally adjacent to and connected to said intermediate portions;

a pair of openings along said side portions and sized and shaped to surround the legs of the person, and pairs of ears at the lateral portions of said end portions, respectively;

one pair of ears being elongate in shape and having proximal portions spaced from a line centered on the longitudinal axis of said cover, free end portions spaced distally from said proximal portions, elastomeric medial portions adjustably spacing and separating said free end portions from said proximal portions, and fixed-position fastening means being provided on said free end portions;

said other pair of ears having zone means for imparting a tensile force distribution pattern which directs stresses away from the edges of said side and end portions while providing a band of support thereacross, and fixed-position fastening means for cooperating with said fixed-position fastening means on said free end portions;

first variable-position fastening means on said other pair of ears mounted on said zone means and second variable-position fastening means on said proximal portions for selective engagement with said first variable-position fastening means, wherein said medial portions stretch to allow adjustment and fastening of said fixed-position fastening means once said variable-position fastening means have been selectively fastened.

2. The invention of claim 1 wherein said zone means comprise inelastic means which narrow in shape in a direction toward said line of said outer cover.

3. The invention of claim 2 wherein said inelastic means are triangularly shaped with the apexes thereof equidistantly spaced from said line of said outer cover.

4. The invention of claim 2 wherein said inelastic means are generally frustoconically shaped.

5. The invention of claim 1 wherein said zone means comprise inelastic means which narrow in shape in a direction away from said line of said outer cover.

6. The invention of claim 1, 2, 5, 3, or 4, wherein said outer cover is resiliently stretchable.

7. The invention of claim 1, 2, 5, 3, or 4 wherein said variable-position fastening means comprise cooperating hook and loop fasteners.

8. The invention of claim 7 wherein said outer cover is resiliently stretchable.

9. The invention of claim 8 wherein said outer cover comprises an elastomeric nonwoven fabric.

10. The invention of claim 9 wherein said fixed-position fastening means comprises cooperating snap-in fasteners.

11. The invention of claim 1 wherein said first and second end portions are resiliently stretchable.

12. The invention of claim 11 wherein said outer cover is resiliently stretchable from about 20 percent to about 200 percent.

13. The invention of claim 12 wherein said outer cover is resiliently stretchable in a direction essentially transverse to said line of said outer cover.

14. The invention of claim 13 wherein said outer cover comprises an elastomeric nonwoven fabric.

15. The invention of claim 1 further comprising an absorbent structure superposed on said intermediate portion and including a liquid-permeable sheet, a liquid-impermeable sheet, and a liquid-absorbing core therebetween.

16. The invention of claim 15 wherein said absorbent structure comprises a discrete insert, including attachment means for attaching and integrating said insert to said outer cover while allowing substantially unrestricted functional stretchability thereof.

17. The invention of claim 1 wherein said fixed-position fastening means comprise cooperating snap-in fasteners.
