Disposable elastic absorbent article having retaining enclosures
View Patent ↗An integral disposable elasticized absorbent article has a front waist portion, a back waist portion, a crotch portion, a pair of spaced apart leg openings, an absorbent core member, and means for tightly fitting the absorbent body to the body of the wearer. The absorbent article has a barrier layer which comprises one or more segments overlying portions of the absorbent core member, and defining one or more retaining enclosures between the barrier layer segments and the underlying portion of the absorbent core member.
1. A disposable elasticized absorbent article having a longitudinal axis and a lateral axis, comprising:
(a) a top sheet, a back sheet, a waist portion having a front waist portion and a back waist portion, a crotch portion and a pair of spaced apart leg openings;
(b) an absorbent layer having a longitudinal axis and a horizontal axis disposed between said top sheet and said back sheet, said absorbent layer being defined by two opposed spaced apart longitudinal sides, each longitudinal side having a proximal end, a distal end and a middle portion, and opposed spaced apart proximal and distal lateral ends;
(c) first elasticized barrier layer wherein said first elasticized barrier layer is a generally concave elasticized end barrier layer having a first end segment attached to said top sheet along a length of the periphery of said absorbent layer between the middle portion and distal end, inclusive, of one of said longitudinal sides, a second end segment opposite said first end segment attached to said top sheet along a length of the periphery of said absorbent layer between the middle portion and proximal end, inclusive, of the other of said longitudinal sides, and an intermediate segment connecting said first and second end segments attached to said top sheet along one of said lateral ends of said absorbent layer, thereby forming a retaining enclosure between said barrier layer and said top sheet;
said first elasticized barrier layer having an inner edge
(i) defining a partially continuous configuration having a discontinuity in the crotch portion along said longitudinal side, said discontinuity being spaced apart from endpoints of said inner edge along said longitudinal side, and
(ii) extending for essentially its entire length non-parallel to said longitudinal axis.
2. A disposable elasticized absorbent article having a longitudinal axis and a lateral axis, comprising:
(a) a top sheet, a back sheet, a waist portion having a front waist portion and a back waist portion, a crotch portion and a pair of spaced apart leg openings;
(b) an absorbent layer having a longitudinal axis and a horizontal axis disposed between said top sheet and said back sheet, said absorbent layer being defined by two opposed spaced apart longitudinal sides, each longitudinal side having a proximal end, a distal end and a middle portion, and opposed spaced apart proximal and distal lateral ends; and
(c) first elasticized barrier layer wherein said first elasticized barrier layer is a generally concave elasticized side barrier layer having a first end segment attached to said top sheet along a length of the periphery of said absorbent layer between the middle portion and distal end, inclusive, of one of said longitudinal sides, and a second end segment opposite said first end segment attached to said top sheet along a length of the periphery of said absorbent layer between the middle portion and proximal end, inclusive, of said one longitudinal side, and an intermediate segment connecting said first and second end segments attached to said top sheet along said one longitudinal side, thereby forming a retaining enclosure between said barrier layer and said top sheet;
said first elasticized barrier layer having an inner edge
(i) defining a partially continuous configuration having a discontinuity in the crotch portion along said longitudinal side, said discontinuity being spaced apart from endpoints of said inner edge along said longitudinal side, and
(ii) extending for essentially its entire length non-parallel to said longitudinal axis.
3. The article of claim 1 wherein said inner edge of said first elasticized barrier layer is elasticized.
4. The article of claim 2 wherein said inner edge of said first elasticized barrier layer is elasticized.
5. The article of claim 1 wherein each of said first elasticized barrier layer is a vapor-pervious nonwoven.
6. The article of claim 2 wherein each of said first elasticized barrier layer is a vapor-pervious nonwoven.
