  • Patent number: 4817788
    Abstract: A through the wash, compact, laminated laundry product (1) comprising powdered laundry actives laminated between two plies, at least one ply of which is a strong wet strength, high stretch tissue (5) having a multiplicity of deeply embossed (stretched) nonconnecting tissue cup-like depressions (2) containing the powdered actives with the other ply (4) covering the cups. The plies are sealed with a glue pattern (22) around the cup rims (5a). The high stretch tissue is stretched 15% to 100% to form said deeply embossed (stretched) cups and is made to survive the rigors of a washing machine.

  • Patent number: 4638907
    Abstract: A through the wash, compact, laminated laundry product (1) comprising powdered laundry actives laminated between two plies, at least one ply of which is a strong wet strength, high stretch paper tissue (5) having a multiplicity of deeply embossed (stretched) nonconnecting tissue cup-like depressions (2) containing the powdered actives with the other ply (4) covering the cups. The strong wet strength paper has a wet cross-directional (CD) tensile of from about 78.7 g/cm to about 315 g/cm (200-800 g/in). The plies are sealed with a glue pattern (22) around the cup rims (5a). The high stretch paper is made to withstand an embossed stretch of 15% to 100% to form said deeply embossed (stretched) cups and to survive the rigors of a washing machine.

  • Patent number: 3955577
    Abstract: A disposable diaper combining improved softness and sufficient strength to resist in use tearing and shredding in a single structure, thereby producing better compliance and fit when the structure is applied to the wearer, and hence improved comfort as well as better containment of waste fluids deposited thereon. In a preferred embodiment, a disposable diaper of the present invention employs an air laid absorbent cellulosic core reinforced by the application of a hydrophobic resin at relatively low levels of solids addition to one side thereof with subsequent drying, curing and calendering to the desired overall density. With sufficient strength built into the resin treated surface of the absorbent core structure, the unreinforced surface of the absorbent core can be adhered directly to a soft, waterproof backsheet, thereby producing a unique softness, texture and hand.
