Abstract
Abstract Fluid permeable inner facing and impermeable outer facings are biased cut with reduced width between oppositely disposed larger ends, and absorbent filler sandwiched between the facings. A strip of inner facing as long as a diaper periphery is wrapped around a rolled belt of absorbent filler and the facing edges of inner and outer facings are sewed together with the edges of the wrapped belt of filter to form a border welted edge. Fastening flaps extend from the upper part of the diaper transversely to fasten by adhesive tape to a folded up lower portion of the diaper and secure it in place.

Claim 1
Independent Claim
155 words
An improved disposable diaper comprising: (a) inner and outer facings respectively fluid permeable and impermeable cut on a bias from said materials for longitudinal and transverse stretchability, and with reduced width intermediate oppositely disposed ends for lessening diaper bulk between legs and around waist of wearer, one said outer facing end being transversely extended outwardly in opposite directions for fastening flaps; (b) absorbent filler sandwiched between said facings for absorbing fluid through said liquid permeable facing; (c) a belt of said absorbent filter wrapped in a bias cut strip of said permeable facing the length of a permeable facing periphery for fixing in a bias cut welted edge closing said facings against leakage therethrough and thereunder; and (d) fastening flaps extending transversely from an end of said impermeable facing for stretch folding forwardly around and over an opposite diaper end upwardly folded between the legs of said wearer with no overlapping of absorbent filler parts.
