Abstract
A disposable waste-containment garment such as a disposable diaper, an external incontinent protection garment for adults (e.g. adult incontinent briefs), an external catamenial, or a disposable liner for either a disposable diaper or an incontinent brief. The garment, which may be elasticized by, for example, having elasticized leg cuffs and waistbands, comprises an absorbent core comprising substantially unbonded fibers disposed between a liquid permeable lamina and a liquid impermeable backsheet, and the liquid permeable lamina and the absorbent core are bonded together in face to face relation with an open pattern of adhesive: preferably a fine scale reticulated network of filaments of pressure sensitive hot melt adhesive having a weight of from about one-half (1/2) milligram to about three (3) milligrams per square inch (from about 0.8 to about 4.7 grams per square meter) but, more preferably, from about one-and-three-tenths (1.3) milligrams to about two-and-three-tenths (2.3) milligrams per square inch (from about 2.0 to about 3.6 grams per square meter) and, most preferably, about two (2) milligrams per square inch (about 3.1 grams per square meter). In a preferred embodiment of such a garment, the liquid permeable lamina is a portion of a wet-strength-tissue envelope in which the absorbent core is disposed and secured; and the core further comprises elements of highly liquid absorbent matter which elements may be fibrous or particulate or the like in form. Additionally, such garments may further comprise additional laminae which may also be adhesively secured together or to the above enumerated elements: preferably in the manner in which the lamina described above is adhesively secured to the absorbent core.
