Claim:
Elastically stretchable disposable pants having a ventral longitudinal axis and comprising: a pair of elastically stretchable sheet members; a front waist region having side edges; a rear waist region opposed to said front waist region; a waist-opening and a pair of leg-openings defined by bonding said front and rear waist regions at edge portions thereof to each other; and a pair of spaced apart substantially inelastic guide zones provided between said central longitudinal axis and each of said side edges of said front and rear waist regions, and extending longitudinally of said pants between said waist-opening and each of each of said leg-openings, each of said substantially inelastic guide zones of said pair of substantially inelastic guide zones comprising a discrete array of discrete inelastic portions of the elastically stretchable sheet members, said discrete arrays having upper terminal ends which terminate near the waist-opening and lower terminal ends that are spaced apart from the leg-openings, said substantially inelastic guide zones being configured to prevent portions of the disposable diaper in a vicinity of the substantially inelastic guide zones from stretching along a direction parallel to the central longitudinal axis.
