Disposable garments with multiple strand elasticized openings

Claim 2

In a disposable garment of the type having at least one opening intended to fit snugly about a wearer's body, which opening is defined by an exterior marginal portion of material and an interior marginal portion of material together with elastic means joined thereto to provide an elasticized opening for the garment, the improvement wherein: (1) the elastic means consists of a plurality of elastic elements positioned between the exterior marginal portion and the interior marginal portion, and extending substantially about the periphery of the opening; (2) each elastic element has a cross-sectional shape having an aspect ratio in the range of 0.25 to 1 with its shortest axis in the range of about 0.8 to 3.2 mm long and an area in the range of about 0.5 to 8 mm 2 ; wherein each elastic element can have a cross-sectional shape, an aspect ratio, and an area different from the other elastic elements to provide different elastic characteristics thereto; (3) each elastic element is joined to both the exterior marginal portion and the interior marginal portion in a stretched condition to provide an elasticized opening when in a retracted condition; and (4) the elastic elements are spaced from one another in a direction transverse to the direction of stretch of the elements, there beng an unbroken continuous zone of the exterior marginal portion and interior marginal portion between adjacent spaced elastic elements and extending substantially about the periphery of the opening.

Claim 3

A disposable garment according to claim 1, wherein: the exterior marginal portion is part of an outer layer of the disposable garment, and the interior marginal portion is part of an inner layer of a disposable garment.

Claim 4

A disposable garment according to claim 1, wherein: the exterior marginal portion is part of one layer of a disposable garment, and the interior marginal portion is a part of the same layer of the garment folded-over to contact each spaced elastic element.

Claim 5

A disposable garment according to claim 1, 2, or 3 wherein: the exterior and interior marginal portions of material are joined to one another within each zone between spaced elastic elements.

Claim 6

A disposable panty comprising, in combination: an outer cover, a bodyside liner and an absorbent batt therebetween arranged to provide a panty including a front portion and a rear portion interconnected by a central crotch portion, and side seams joining together contacting marginal sections of the front portion and rear portion to define a waist opening and a pair of leg openings; an exterior marginal portion of the outer cover along each leg opening, and an interior marginal portion of the bodyside liner along each leg opening, each leg opening further including: (a) two or three spaced elastic elements extending substantially about the periphery of the leg opening, each having a cross-sectional shape having an aspect ratio in the range of 0.25 to 1 with its shortest axis in the range of about 0.25 to 3.2 mm long an an area in the range of about 0.5 to 8 mm 2 wherein each elastic element can have a cross-sectional shape, an aspect ratio, and an area different from the other elastic elements, (b) each elastic element being joined to both the exterior marginal portion of the outer cover and the interior marginal portion of the bodyside liner along its respective leg opening, and (c) an unbroken continuous zone of the exterior marginal portion of the outer cover and the interior marginal portion of the bodyside liner between adjacent spaced elastic elements along each leg opening, and extending substantially about the periphery of each leg opening, each elastic element being joined at its respective leg opening in a stretched condition to provide an elasticized leg opening when retracted.

Claim 7

A disposable panty comprising, in combination: an outer cover, a bodyside liner and an absorbent batt therebetween arranged to provide a panty including a front portion and a rear portion interconnected by a central crotch portion, and side seams joining together contacting marginal sections of the front portion and rear portion to define a waist opening and a pair of leg openings; an exterior marginal portion of the outer cover along each leg opening, and an interior marginal portion of the bodyside liner along each leg opening, each leg opening further including: (a) two or three spaced elastic elements extending substantially about the periphery of the leg opening, each having a cross-sectional shape having an aspect ratio in the range of 0.25 to 1 with its shortest axis in the range of about 0.25 to 3.2 mm long an an area in the range of about 0.5 to 8 mm 2 wherein each elastic element can have a cross-sectional shape, an aspect ratio, and an area different from the other elastic elements, (b) each elastic element being joined to both the exterior marginal portion of the outer cover and the interior marginal portion of the bodyside liner along its respective leg opening, and (c) an unbroken continuous zone of the exterior marginal portion of the outer cover and the interior marginal portion of the bodyside liner between adjacent spaced elastic elements along each leg opening, and extending substantially about the periphery of each leg opening, each elastic element being joined at its respective leg opening in a stretched condition to provide an elasticized leg opening when retracted.

Claim 8

A disposable panty according to claim 5, further including: an exterior marginal portion of the outer cover and an interior marginal portion of the bodyside liner along the waist opening, and an elastic ribbon joined therebetween, the elastic ribbon having a pair of opposed flat surfaces, one joined to the exterior marginal portion of the outer cover and the other joined to the interior marginal portion of the bodyside liner.

Claim 9

A disposable panty according to claim 6 wherein the flat surfaces of the elastic ribbon are in the range of about 9.5 to 19 mm wide and the elastic ribbon is in the range of about 0.25 to 0.5 mm thick.
