Abstract
A fastener for disposable diapers having a first pair of fastener members (70,72) attached to an outer cover (20) of the disposable diaper, a second pair of fastener members (74,76) attached to the outer cover (20). The fastener members (70,72 and 74,76) have a complementary cross section for mating engagement and are releasably interlockable. Each of the fastener members (70,72,74,76) are sufficiently flexible to prevent skin irritation of a wearer and sufficiently inflexible to prevent unwanted unfastening of the fastener members during normal use. A value (E) (I), the product of the Modulus of Elasticity and the Moment of Inertia is utilized as a measure of the flexibility and inflexibility of the fastener. Each fastener member, for example, fastener member 70 has an essentially flat base portion (90) with an aperture (92) separating a pair of clasps (94,96).
