Pre-fastened absorbent article having simplified fastening features
View Patent ↗Prefastened absorbent articles ( 20 ) may include a singular fastening mechanism that includes an oversized fastener ( 60 ), to provide stability between the front waist region and the back waist region and to maintain the prefastened configuration. The prefastened absorbent articles can include a multiple property fastener ( 60 ) that has at least one engagement zone ( 65 ) and at least one non-abrasive zone ( 67 ).
1. A pant-like, prefastened, disposable absorbent article including an absorbent, a front waist region, a back waist region, a crotch region that extends between and connects the waist regions, a longitudinal direction, a lateral direction, an exterior surface, an interior surface opposite the exterior surface, a pair of laterally opposed side edges and a pair of longitudinally opposed waist edges, the absorbent article further comprising:
a multiple property fastener attached in one of the front waist region and the back waist region, the multiple property fastener comprising at least two zones, at least one engagement zone of a first mechanical fastening material and at least one non-abrasive zone of a second mechanical fastening material wherein the first mechanical fastening material is comprised of a polymeric material selected to have a flexural modulus greater than about 30 kilopounds per square inch and the second mechanical fastening material is comprised of a polymeric material selected to have a flexural modulus between about 7 kilopounds per square inch and about 30 kilopounds per square inch.
2. The absorbent article of claim 1 , wherein the multiple property fastener defines a fastener longitudinal direction, a fastener lateral direction and a fastener area, and there is one said engagement zone covering one half of the fastener area in the fastener longitudinal direction and there is one said non-abrasive zone covering the other half of the fastener area in the fastener longitudinal direction.
3. The absorbent article of claim 1 , wherein the multiple property fastener defines a fastener longitudinal direction, a fastener lateral direction and a fastener area, wherein there is one said engagement zone covering one half of the fastener area in the fastener lateral direction and there is one said non-abrasive zone covering the other half of the fastener area in the fastener lateral direction.
4. The absorbent article of claim 1 , wherein there is one said engagement zone covering a central portion of the fastener area and there is one said non-abrasive zone covering a perimeter that surrounds the central portion of the fastener area.
5. The absorbent article of claim 1 , wherein the fastener has a top portion, a longitudinal center portion and a bottom portion and there is one said engagement zone covering the center portion and the at least one said non-abrasive zone comprises non-abrasive zones covering the top portion and the bottom portion.
6. The absorbent article of claim 1 , wherein the fastener has an exterior portion, a lateral center portion and an interior portion and there is one said engagement zone covering the center portion and the at least one said non-abrasive zone comprises non-abrasive zones covering the exterior portion and the interior portion.
7. The absorbent article of claim 1 , wherein the first mechanical fastening material is made from a polypropylene copolymer.
8. The absorbent article of claim 1 , wherein the second mechanical fastening material is made from a polymer selected from elastomeric thermoplastic polymers and metallocene catalyzed polymers.
9. The absorbent article of claim 1 wherein the absorbent article further includes an engagement surface on the exterior surface that extends to form a pair of front ear portions.
10. The absorbent article of claim 9 wherein the engagement surface is a loop material.
11. The absorbent article of claim 9 wherein the engagement surface is an outer cover material.
12. The absorbent article of claim 9 wherein the front ear portion has an edge and the fastener area of the multiple property fastener is within about 2.54 cm of the edge of the front ear portion.
13. The absorbent article of claim 1 wherein the multiple property fastener is engageable into the front waist region of the article.
14. The absorbent article of claim 1 wherein the multiple property fastener is engageable into the back waist region of the article.
15. The absorbent article of claim 1 wherein the multiple property fastener has a top edge that is generally aligned with one of the waist edges of the article.
