View Patent ↗Methods and systems including an engageable material with a lane of plastic resin extending across an interface of first and second ends of an article, wherein the plastic resin is bonded to the first and second ends such that the first and second ends are joined by the resin; and an array of fastener elements extending from one side of the plastic resin. The fastener elements include engageable heads on stems integrally formed with the lane of the plastic resin such that the two ends releasably engage the engageable material to secure the article.
1. A disposable absorbent article comprising:
a chassis having a first end and a second end that are opposite to one another;
an engageable material attached to the chassis adjacent to the two ends; and
a double closure system attached to the chassis adjacent to one of the two ends opposite the end to which the engageable material is attached, the double closure system comprising a first lane of plastic resin extending across an interface of first and second materials, wherein the first lane of plastic resin is bonded to the first and second materials such that the first and second materials are permanently joined by the first lane of resin;
wherein the double closure system or the engageable material comprises an array of fastener elements extending from one side of a second lane of plastic resin, the fastener elements comprising engageable heads on stems integrally formed with the second lane of the plastic resin; and
wherein the double closure system releasably engages the engageable material to secure the disposable absorbent article to a wearer.
2. The disposable absorbent article of claim 1 wherein the engageable material has hook engageable loops.
3. The disposable absorbent article of claim 1 wherein the first and second ends form a butt joint.
4. The disposable absorbent article of claim 1 wherein the engageable material is located on two opposite sides of the double closure system.
5. The disposable absorbent article of claim 1 wherein the first lane of plastic resin has a folding feature comprising a V-shaped notch.
6. The disposable absorbent article of claim 5 wherein the first lane of plastic resin is spaced apart from a second lane of plastic resin, the second lane of plastic resin having an array of fastener elements comprising engageable heads on stems integrally formed with the second lane of the plastic resin.
7. The disposable absorbent article of claim 6 wherein the second lane of plastic resin is located on the first material.
8. The disposable absorbent article of claim 6 wherein the second lane of plastic resin is located on the second material.
9. The disposable absorbent article of claim 8 further comprising, on the first material, a third lane of the plastic resin with which the fastener elements are integrally formed.
10. The disposable absorbent article of claim 9 wherein the second material is pivotable about the folding feature to releasably engage the engageable material.
11. The disposable absorbent article of claim 10 wherein the first lane of resin is bonded to a first end of the second material.
12. The disposable absorbent article of claim 10 wherein the first lane of resin is bonded to a middle portion of the second material.
