Abstract

A process for providing a package of prefastened articles includes manufacturing an article having a chassis with an absorbent assembly located between an outer cover and a body side liner. The chassis also includes a first waist region and a second waist region; a refastenable seam joining a first distal portion of the first waist region to a first distal portion of the second waist region; a first refastenable bond connecting the first distal portion of the first waist region and the first distal portion of the second waist region. The first distal portion of the first waist region is folded and bonded to itself with a releasable bond having a first releasable bond peel strength. The first refastenable bond peel strength is greater than the first releasable bond peel strength. The process also includes rupturing the releasable bond and packaging the article.

Claims (16)

1. A process for providing a package of prefastened articles comprising:

manufacturing a prefastened article, comprising a chassis including an absorbent assembly located between an outer cover and a body side liner, the chassis also 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 and 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;

rupturing the releasable bond; and

packaging the article.

2. The process 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 process 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 process of claim 2 , wherein the ratio of the refastenable bond peel strength to the releasable bond peel strength is greater than 50.

5. The process of claim 1 , wherein the refastenable bond comprises hook and loop, cohesive, adhesive or tape.

6. The process of claim 1 , wherein the releasable bond comprises an ultrasonic bond.

7. The process of claim 1 , wherein the releasable bond comprises a pressure bond.

8. The process of claim 1 , wherein the releasable bond comprises an adhesive bond.

9. The process of claim 1 , wherein the releasable bond is ruptured before the article is packaged.

10. A process for providing a package of prefastened articles comprising:

manufacturing a prefastened article, comprising a chassis including an absorbent assembly located between an outer cover and a body side liner, the chassis also 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 and 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;

rupturing the releasable bond 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; and

packaging the article wherein the releasable bond is ruptured before the article is packaged.
