Patent ID: 8766031

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, said absorbent core comprising: a first substrate layers; a first discontinuous layer of absorbent particulate polymer material deposited on said first substrate layer; a first layer of thermoplastic material, wherein said first layer of thermoplastic material contacts at least portions of said absorbent particulate polymer material and at least portions of said first substrate layers forming areas of junction where said thermoplastic material of said first layer of thermoplastic material contacts said first substrate layers; a second substrate layer; a second discontinuous layer of absorbent particulate material deposited on said second substrate layer; and a second layer of thermoplastic material, wherein second layer of thermoplastic material contacts at least portions of said absorbent particulate polymer material and at least portions of said second substrate layer forming areas of junction where said thermoplastic material of said second layer of thermoplastic material contacts said second substrate layer, wherein said first and second substrate layers are joined such that said first and second layer of thermoplastic material of said first and second substrate 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, wherein at least portions of said first and second substrate layers do not contact each other, said absorbent core includes absorbent particulate polymer material having a Saline Flow Conductivity of at least about 20×10 −7 (cm 3 ×sec)/gram, wherein said absorbent core has less than about 10% of cellulose fibrous material as compared to the weight of said absorbent particulate polymer material, wherein at least one of said first, and said second discontinuous layers of absorbent particulate polymer material has openings therein such that the areas of junction of said discontinuous layer having openings are discrete such that areas of said absorbent particulate polymer material of said discontinuous layer having openings are connected to one another.
