Abstract
The invention provides a disposable urinary pad having high liquid impact capacity, high liquid retention, and allows the skin of the wearer to remain dry. The pad is comprised of a liquid-impermeable, substantially flexible shell containing a fibrous web superstructure substantially filling the shell and an absorbent medium between the superstructure and the bottom of the shell.
Claims30
A disposable urinary pad comprising a liquid-impermeable substantially flexible relatively thin shell having a length from about 4 to about 12 inches, a width from about 2 to about 7 inches, and a depth from about 0.5 to about 2.5 inches;
- a superstructure placed in and substantially filling said shell, said superstructure consisting essentially of a fibrous web of hydrophobic, wet resilient, dry resilient fibers, said web allowing liquid to pass through the web at a rate of at least about 20 cc/second;
- and
- an absorbent medium in intimate contact with at least a portion of said superstructure and at least a portion of said shell,
- said pad having a transverse recovery when wet of at least about 80% following compression of up to 25% of its width wherein said superstructure is a primary contributor to said recovery.
A disposable urinary pad comprising a liquid-impermeable, substantially flexible, relatively thin shell having a length from about 4 to about 12 inches, a width from about 2 to about 7 inches, and a depth from about 0.5 to about 2.5 inches,
- a superstructure placed in and substantially filling said shell, said superstructure consisting essentially of a corrugated fibrous web of hydrophobic, wet resilient, dry resilient fibers, said web in its uncorrugated form, allowing liquid to pass through the web at a rate of at least about 20 cc/second;
- and
- an absorbent medium comprised of superabsorbent material, hydrophilic fibers, a nonwoven web of hydrophilic fibers, wadding, tissue, peat moss, or mixtures thereof, in intimate contact with at least a portion of said superstructure and at least a portion of said shell,
- said pad having a transverse recovery when wet of at least about 80% following compression of up to 25% of its width.
A disposable urinary pad comprising an ethylenevinyl acetate copolymer shell which is substantially flexible, relatively thin shell having a length from about 4 to about 12 inches, a width from about 2 to about 7 inches, and a depth from about 0.5 to about 2.5 inches,
- a superstructure placed in and substantially filling said shell, said superstructure consisting essentially of a corrugated polyester fiber web, said web allowing liquid to pass through the web at a rate of at least about 20 cc/second;
- and
- an absorbent medium in intimate contact with at least a portion of said superstructure and at least a portion of said shell, said absorbent medium comprising an acrylic fiber web and superabsorbent material,
- said pad having a transverse recovery when wet of at least about 90% following compression of up to 25% of its width.
