ABSORBENT ARTICLES HAVING AN ABSORBENT CORE CONFIGURED TO DEFINE A CONTAINMENT ZONE
The present disclosure relates to absorbent articles having an absorbent core that can comprise a laminate longitudinally folded such that the absorbent core includes a lower laminate layer and, within each of first and second longitudinally-extending edge regions, one or more folded laminate layers. A center region of the lower layer can be bonded to a chassis and can span a lateral distance smaller than the width of the absorbent core such that at least a portion of the absorbent core in each of the edge regions is configured to lift away from the chassis. The present absorbent cores can thus define a containment zone to reduce liquid and/or feces leakage.
1 . An absorbent article comprising:
a chassis having opposing front and rear portions and a crotch portion extending longitudinally between the front and rear portions, wherein the crotch portion is configured to conform about at least one of a wearer's groin area, perineum, and rear when the chassis is in a wearable configuration;
an absorbent core extending longitudinally along the crotch portion and comprising a laminate that includes two or more substrate laminae and one or more absorbent laminae, wherein:
each of the absorbent lamina(e) comprises superabsorbent polymer (SAP);
a first one of the absorbent lamina(e) is disposed between first and second ones of the substrate laminae; and
the laminate is longitudinally folded such that the absorbent core includes:
a lower layer of the laminate spanning a lateral width of the absorbent core; and
one or more folded layers of the laminate disposed above the lower layer within each of first and second longitudinally-extending edge regions, each of the edge regions spanning less than 50% of the width;
wherein a center region of the lower layer is bonded to the crotch portion, the center region spanning a lateral distance smaller than the width of the absorbent core such that at least a portion of the absorbent core in each of the edge regions is configured to lift away from the chassis when the chassis is in the wearable configuration.
2 . The absorbent article of claim 1 , comprising first and second longitudinally-extending cuffs, each having:
a first portion coupled to the crotch portion; and
a second portion bonded to at least one of the folded layer(s) of a respective one of the first and second edge regions;
wherein the second portion is configured to lift away from the chassis when the chassis is in the wearable configuration such that the cuff urges at least a portion of the absorbent core away from the chassis.
3 . The absorbent article of claim 1 , comprising first and second longitudinally-extending cuffs, each bonded to an uppermost one of the folded layer(s) of a respective one of the first and second edge regions such that:
a first side of the cuff is disposed closer to the other of the edge regions than is a second side of the cuff; and
the second side is configured to lift away from the chassis when the chassis is in the wearable configuration such that:
the second side is further from the chassis than is the first side; and
the cuff urges at least a portion of the absorbent core away from the chassis.
4 . The absorbent article of claim 1 , wherein:
the absorbent core has and extends longitudinally between first and second ends; and
for each of the first and second ends, an end cap is coupled to the chassis and extends laterally across the end.
5 . The absorbent article of claim 1 , wherein the laminate is folded such that for each of the first and second edge regions the one or more folded layers comprise two or more folded layers.
6 . The absorbent article of claim 5 , wherein the laminate is folded such that for each of the first and second edge regions, one of the folded layers:
extends inwardly from a fold of the laminate to an end of the laminate such that the end is disposed closer to the other of the edge regions than is the fold; and
is disposed below at least one other of the folded layers.
7 . The absorbent article of claim 5 , wherein for each of the first and second edge regions, a first one of the folded layers is bonded to a second one of the folded layers with an adhesive.
8 . The absorbent article of claim 1 , wherein the first substrate lamina comprises tissue.
9 . The absorbent article of claim 8 , wherein the second substrate lamina comprises a nonwoven and, for the lower layer, the second substrate lamina is configured to be disposed closer to a wearer than is the first substrate lamina when the absorbent article is worn.
10 . The absorbent article of claim 1 , wherein the laminate is folded such that, for each of the first and second edge regions:
a lowermost one of the folded layer(s) has and extends laterally between first and second portions, the first portion disposed closer to the other of the edge regions than is the second portion; and
the first portion is configured to be disposed on the lower layer when the chassis is in the wearable configuration.
11 . The absorbent article of claim 1 , wherein the SAP of each of the absorbent lamina(e) has a centrifuge retention capacity between 33 and 52 grams per gram (g/g).
12 . The absorbent article of claim 1 , wherein the SAP of each of the absorbent lamina(e) has a basis weight between 60 and 75 grams per square meter (gsm).
13 . The absorbent article of claim 1 , comprising:
a longitudinally-extending insert coupled to the laminate such that for each of the first and second edge regions a portion of the insert is disposed above the lower layer and below at least one of the folded layer(s);
wherein the insert comprises at least one of:
fluff and SAP; and
a through-air bonded polymer nonwoven.
14 . The absorbent article of claim 1 , wherein:
the two or more substrate laminae comprise three or more substrate laminae;
the one or more absorbent laminae comprise two or more absorbent laminae; and
a second one of the absorbent laminae is disposed between the second substrate lamina and a third one of the substrate laminae.
15 . The absorbent article of claim 1 , wherein each of the first and second edge regions spans at least 20% of the width of the absorbent core.
16 . The absorbent article of claim 2 , wherein the laminate is folded such that for each of the first and second edge regions the one or more folded layers comprise two or more folded layers.
17 . The absorbent article of claim 16 , wherein the laminate is folded such that for each of the first and second edge regions, one of the folded layers:
extends inwardly from a fold of the laminate to an end of the laminate such that the end is disposed closer to the other of the edge regions than is the fold; and
is disposed below at least one other of the folded layers.
18 . The absorbent article of claim 16 , wherein for each of the first and second edge regions, a first one of the folded layers is bonded to a second one of the folded layers with an adhesive.
19 . The absorbent article of claim 2 , wherein the first substrate lamina comprises tissue.
20 . The absorbent article of claim 19 , wherein the second substrate lamina comprises a nonwoven and, for the lower layer, the second substrate lamina is configured to be disposed closer to a wearer than is the first substrate lamina when the absorbent article is worn.
