Elastic form-fitting closure constructions for disposable garments

In a disposable garment including an outer marginal portion of material and an interior marginal portion of material along a part of said garment intended to fit around a portion of a wearer's body, and an elastic element joined thereto to provide an elasticized opening for said garment,

• the improvement wherein:
• said elastic element includes an exterior surface disposed in mutually facing relationship with said outer marginal portion of material and an inner surface joined to said interior marginal portion of material,
• an outer edge portion of said elastic element, said outer marginal portion of material, and said interior marginal portion of material are substantially coincident,
• said outer marginal portion of material has a thickness in the range of about 0.0003 to about 0.03 inches, and a flexural rigidity in the range of about 0.002 to about 0.1 cm-g, and
• a plurality of bond points are uniformly disposed between and join together the mutually facing said elastic element exterior surface and said outer marginal portion of material, the area of each said bond point is between about 0.05 to about 3 mm.sup.2, the distance between adjacent ones of said bond points in the direction of elongation of said elastic element prior to joining said elastic element to said outer marginal portion is between about 0.05 to about 4 mm, and the total area of said bond points is between about 5% to about 80% of the area of the mutually facing said exterior surface and said outer marginal portion,
• said elastic element is joined to said bond points when in an elongated condition and remains joined only to said bond points when in a retracted condition to provide an elasticized opening having micro-ribbing of said outer marginal portion of material between said bond points.
