Abstract
A disposable absorbent article that includes a frangible bonding agent for maintaining the absorbent article in a predetermined configuration. The frangible bonding agent may be disposed on a fastening system in order to maintain one or more portions of the fastening system in a particular position during manufacturing but still provide an easy-to-open fastener when used by a consumer.
Claims18
A disposable absorbent article comprising:
- a mechanical fastening system comprising first and second opposing surfaces, a web, and at least one engaging member joined to the web;
- and
- a frangible bonding agent disposed on a first portion of the first surface of the fastening system;
- wherein the engaging member includes a plurality of engaging elements and the web includes a plurality of receiving elements that are engageable with the engaging elements;
- wherein the frangible bonding agent is a fugitive hot-melt adhesive that is disposed on and crystallizes on one or more of the receiving elements and comprises a high melt point wax and a low melt point wax.
2 more elements
A disposable absorbent article comprising:
- a mechanical fastening system comprising first and second opposing surfaces, a web, and at least one engaging member joined to the web;
- and
- a frangible bonding agent disposed on a first portion of the first surface of the fastening system, wherein the frangible bonding agent is a fugitive hot-melt adhesive that crystallizes and is capable of forming a bond that has an Initial Peel value and an Aged Peel value and the Aged Peel value is less than the Initial Peel value according to the Coupon Peel Test;
