Abstract
A laminated structure having a gathered marginal area which provides an improved fit about a portion of the human body, said laminated structure comprising an elastic member disposed between first and second substrates of flexible gatherable material, said elastic member comprising a plurality of interconnected longitudinally extending elastic elements defining apertures therebetween, the longitudinally extending elements having different cross-sectional areas to provide varying degrees of tension across the width of the marginal area and the first and second substrates of said laminated structure being secured together through at least some of said apertures.
Claims29
A laminated structure having a gathered marginal area to provide improved fit about a portion of the human body comprising:
- first and second layers positioned adjacent to one another, said layers being formed of flexible gatherable material, an elastic member disposed between said layers in the marginal area thereof, said elastic member comprising a plurality of interconnected longitudinally extending elastic elements defining apertures therebetween, said elements having different cross sectional areas to provide varying degrees of tension across the width of said marginal area, said first and second layers being secured together through at least some of said apertures.
A disposable diaper comprising:
- a moisture-permeable facing layer, an absorbent panel at one side of said facing layer, said absorbent panel being smaller than said facing layer so that marginal portions of the facing layer extend outwardly beyond the edges of said absorbent panel;
- a moisture-impervious backing layer at the side of said absorbent panel opposite said facing layer, said backing layer being larger than said absorbent panel so that marginal portions of the backing layer extend outwardly beyond the edges of said absorbent panel;
- means bonding said facing and backing layers to one another;
- and an elastic member disposed in at least one marginal portion, and affixed therein, said elastic member comprising a plurality of interconnected longitudinally extending elastic elements defining apertures therebetween, said elements having differential cross-sectional areas to provide varying degrees of tension across the width of said marginal portions.
A disposable diaper comprising:
- a moisture-permeable facing layer;
- an absorbent panel at one side of said facing layer, said absorbent panel being smaller than said facing layer so that side marginal portions of the facing layer extend outwardly beyond the side edges of said absorbent panel;
- a moisture-impervious backing layer at the side of said absorbent panel opposite said facing layer, said backing layer being larger than said absorbent panel so that side marginal portions of the backing layer extend outwardly beyond the side edges of said absorbent panel;
- means bonding said facing and backing layers to one another;
- and an elastic member disposed in each of said side marginal portions, and affixed therein, said elastic members comprising a plurality of interconnected longitudinally extending elastic elements defining apertures therebetween, said elements having different cross-sectional areas to provide varying degrees of tension across the width of said marginal portions.
A disposable diaper as in clain 13 wherein said facing and backing layers are secured to each other through at least some of said apertures.
A disposable diaper comprising:
- a first outer layer in the form of a moisture-impervious backing;
- an absorbent panel positioned in superposed relationship with respect to said backing, said panel being smaller than said backing and spaced inwardly from the sides and ends thereof;
- a second outer layer in the form of a moisture-pervious facing positioned in superposed relationship with respect to said panel, said facing being larger than said panel and having side and end marginal portions thereof secured to said backing;
- an elastic member disposed in each side margin of the diaper, and affixed therein, said elastic member comprising a plurality of interconnected longitudinally extending gathering elements defining apertures therebetween, said elements having different cross-sectional areas to provide varying degrees of tension across the width of said side marginal portions.
A disposable undergarment, suitable for use in training infants or by incontinent children or adults, which comprises a front portion, a rear portion, and a crotch portion connecting said front and rear portions;
- both said margins of said front portion being joined to respective side margins of said rear portion so as to define a waist portion and leg apertures, said undergarment having a moisture-pervious inner layer adapted to contact the wearer's skin, an outer layer and an intermediate liquid absorbent panel disposed therebetween, and an elastic member disposed between the ends of the inner layer and the outer layer at the rear portion, said elastic member comprising a plurality of interconnected longitudinally extending elastic elements defining apertures therebetween, said elements having different cross-sectional areas to provide varying degrees of tension across the width of said rear portion, said inner layer and said outer layer being secured together through at least some of said apertures.
