Patent ID: 8319005

Claim:
A disposable absorbent diaper comprising: a chassis including a liquid impervious backsheet and a liquid pervious topsheet; a reclosable fastening system joined to said chassis for securing said diaper to a wearer; and an absorbent core located between said backsheet and said topsheet which includes first and second substrate layers and first and second discontinuous layers of absorbent particulate polymer material deposited respectively thereon, and first and second continuous layers of thermoplastic material laid down on top of said first and second layers of absorbent particulate polymer material and said first and second substrate layers; wherein said first and second thermoplastic materials contact at least portions of said first and second absorbent particulate polymer materials and at least portions of said first and second substrate layers forming areas of junction where said first and second thermoplastic materials contact said substrate layers; said first and second substrate layers are combined together such that said first and second thermoplastic material layers contact one another and such that said absorbent particulate polymer material of said first substrate layer faces said areas of junction of said second substrate layer and said absorbent particulate polymer material of said second substrate layer faces said areas of junction of said first substrate layer, such that the centers of said areas of junction are offset and do not face each other, wherein said thermoplastic material has a softening point in a range from about 50° C. to about 300° C., a glass transition temperature of less than about 25° C., and a storage modulus G′ measured at 60° C. of less than about 300,000 Pa; wherein said absorbent core has less than about 10% of cellulose fibrous material as compared to the weight of said particulate absorbent polymer.
