Abstract
A disposable diaper comprising, an absorbent pad assembly, and a tape fastener comprising an elongated pressure-sensitive tape strip having a first section attached to a surface of the pad assembly and a second securement section extending from the first section in a longitudinal direction of the tape strip for securing the diaper about an infant. The tape strip has a backing of a non-reinforced, extensible polymeric film, with the film having an ultimate elongation of greater than 50% in the longitudinal direction of the tape strip, and having modulus properties such that the film has an elongation of 50% at 5-10 lbs./in. width of force as applied to the second section of the tape strip in the longitudinal direction thereof.
Claims7
A disposable diaper comprising, an absorbent pad assembly, and a tape fastener comprising an elongated pressure-sensitive tape strip having a first section attached to a surface defined by a sheet of the pad assembly and a second securement section extending from the first section in a longitudinal direction of the tape strip for securing the diaper about an infant, said tape strip having means for extending and elongating in length previous to failure of said sheet when forces are applied in a longitudinal direction of the strip comprising an adhesively coated backing of a non-reinforced, extensible, polymeric film, with said film having an ultimate elongation of greater than 50% in the longitudinal direction of the tape strip, and having modulus properties such that said film has an elongation of 50% at 5-10 lbs/in. width of force as applied to the second section of the tape strip in the longitudinal direction thereof.
