Combination of refastenable and releasable bonds
View Patent ↗A refastenable, pant-like garment, including a chassis including a first waist region and a second waist region, together defining a waist opening and first and second leg openings. The garment also includes a first refastenable seam joining a first distal portion of the first waist region to a first distal portion of the second waist region. The first refastenable seam includes a first refastenable bond connecting the first distal portion of the first waist region and the first distal portion of the second waist region having a first refastenable bond peel strength.
1. A prefastened article, comprising:
a chassis including a first waist region and a second waist region, together defining a waist opening and first and second leg openings;
a refastenable seam joining a first distal portion of the first waist region to a first distal portion of the second waist region, and including a first refastenable bond connecting the first distal portion of the first waist region and the first distal portion of the second waist region having a first refastenable bond peel strength, the first distal portion of the first waist region being folded and bonded to itself with a releasable bond having a first releasable bond peel strength, wherein the first refastenable bond peel strength is greater than the first releasable bond peel strength.
2. The article of claim 1 wherein separating the first waist region from the second waist region initially stresses the refastenable bond and the releasable bond predominantly in peel, then ruptures the releasable bond predominantly in peel, then stresses the refastenable bond predominantly in shear.
3. The article of claim 2 , wherein a ratio of the refastenable bond peel strength to the releasable bond peel strength is greater than 1.5.
4. The article of claim 2 , wherein the ratio of the refastenable bond peel strength to the releasable bond peel strength is greater than 50.
5. The article of claim 1 , wherein the refastenable bond comprises hook and loop, cohesive, adhesive or tape.
6. The article of claim 1 , wherein the releasable bond comprises an ultrasonic bond.
7. The article of claim 1 , wherein the releasable bond comprises a pressure bond.
8. The article of claim 1 , wherein the releasable bond comprises an adhesive bond.
9. A process for providing a package of prefastened articles comprising:
manufacturing the article of claim 1 ;
rupturing the releasable bond; and
packaging the article.
10. A refastenable, pant-like garment, comprising:
a chassis including a first waist region and a second waist region, together defining a waist opening and first and second leg openings;
a first refastenable seam joining a first distal portion of the first waist region to a first distal portion of the second waist region, and including a first refastenable bond connecting the first distal portion of the first waist region and the first distal portion of the second waist region having a first refastenable bond peel strength, the first distal portion of the first waist region being folded and bonded to itself with a releasable bond having a first releasable bond peel strength, wherein the first refastenable bond peel strength is greater than the first releasable bond peel strength; and
a second refastenable seam joining a second distal portion of the first waist region to a second distal portion of the second waist region, and including a second refastenable bond connecting the second distal portion of the first waist region and the second distal portion of the second waist region having a second refastenable bond peel strength, the second distal portion of the first waist region being folded and bonded to itself with a releasable bond having a second releasable bond peel strength, wherein the second refastenable bond peel strength is greater than the second releasable bond peel strength.
11. The garment of claim 10 , wherein the first distal portion of the second waist region is folded and bonded with a first permanent bond having a first permanent bond peel strength, the first permanent bond peel strength being greater than the first refastenable bond peel strength and the first releasable bond peel strength, and the second distal portion of the second waist region is folded and bonded with a first permanent bond having a second permanent bond peel strength, the second permanent bond peel strength being greater than the second refastenable bond peel strength and the second releasable bond peel strength.
12. The garment of claim 11 , wherein the first and second permanent bonds comprise ultrasonic bonds.
13. The garment of claim 10 , wherein a ratio of the first refastenable bond peel strength to the first releasable bond peel strength is greater than 1.5, and a ratio of the second refastenable bond peel strength to the second releasable bond peel strength is greater than 1.5.
14. The garment of claim 10 , wherein a ratio of the first refastenable bond peel strength to the first releasable bond peel strength is greater than 50, and a ratio of the second refastenable bond peel strength to the second releasable bond peel strength is greater than 50.
15. The article of claim 10 , wherein the first and second refastenable bonds comprise hook and loop, cohesive, adhesive or tape.
16. The article of claim 10 , wherein the first and second releasable bonds comprise ultrasonic bonds.
17. The article of claim 10 , wherein the first and second releasable bonds comprise pressure bonds.
18. The article of claim 10 , wherein the first and second releasable bond comprise adhesive bonds.
