Abstract
Abstract Here is disclosed an arrangement of elastic means surrounding respective leg-openings of garments such as disposable diaper, wherein the elastic means surrounding each of the leg-openings comprises a plurality of first elastic members and a plurality of second elastic members; the first elastic members are positioned substantially along a front half of the leg-opening while the second elastic members are positioned substantially along a rear half of the leg-opening; the first and second elastic members have their tensile stress gradually decreasing from their longitudinally inner ends toward their longitudinally outer ends; and the first and second elastic members have their inter-member spacings gradually enlarged from their longitudinally inner ends toward their longitudinally outer ends.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
146 words
Disposable garments having a topsheet, a backsheet and elastic means provided along leg-openings defined at opposite sides of a crotch area connecting front and rear sections of the top- and backsheets, characterized by that: the elastic means surrounding each of the leg-openings comprises first and second elastic members; the first elastic member is positioned substantially along a front half of both leg-openings and traversing the approximate middle of the crotch area while the second elastic member is positioned substantially along a rear half of both leg-openings and traversing the approximate middle of the crotch area so that the first and second elastic members intersect each other the middle area of the crotch area of each leg-opening; and the first and second elastic members have their tensile stress gradually decreasing from locations adjacent the middle of each leg opening toward locations adjacent end of each leg opening.
Claim 2
Dependent Claim
146 words

Claim 3
Dependent Claim
159 words
Disposable garments having a topsheet, a backsheet and elastic means provided along leg-openings defined at opposite sides of a crotch area connecting front and rear sections of the top- and backsheets, characterized by that: the elastic mean surrounding each of the leg-openings comprises a plurality of first elastic members and a plurality of second elastic members: the first elastic members are positioned substantially along a front half of each leg-opening and traversing the approximate middle of the crotch area while the second elastic members are positioned substantially along a rear half of each leg-opening and traversing the approximate middle of the crotch area so that the first and second elastic members intersect each other adjacent the middle area of the crotch area of each leg-opening; and the spacings between each of the first elastic members and between each of the second elastic members are gradually enlarged from their location adjacent the middle of each leg opening toward their ends.
Claim 4
Dependent Claim
159 words
Disposable garments having a topsheet, a backsheet and elastic means provided along leg-openings defined at opposite sides of a crotch area connecting front and rear sections of the top- and backsheets, characterized by that: the elastic mean surrounding each of the leg-openings comprises a plurality of first elastic members and a plurality of second elastic members: the first elastic members are positioned substantially along a front half of each leg-opening and traversing the approximate middle of the crotch area while the second elastic members are positioned substantially along a rear half of each leg-opening and traversing the approximate middle of the crotch area so that the first and second elastic members intersect each other adjacent the middle area of the crotch area of each leg-opening; and the spacings between each of the first elastic members and between each of the second elastic members are gradually enlarged from their location adjacent the middle of each leg opening toward their ends.
Claim 5
Dependent Claim
53 words
Disposable garments as recited in claim 1, wherein the first and second elastic members respectively comprise plural elastic members and the spacings between each of the first elastic members and between each of the second elastic members are gradually enlarged from their location adjacent the middle of each leg opening toward their ends.
Claim 6
Dependent Claim
33 words
Disposable garments as recited in claim 2, wherein the first and second elastic members have their tensile stress gradually decreasing from their location adjacent the middle of each leg opening toward their ends.
