Abstract
The invention generally provides a pad that has a double system of baffles at the edges. The pad is composed of an outer impervious backing sheet, an inner absorbent layer, and a body-side permeable web. The impervious backing sheet is of greater dimensions than the absorbent and is folded over the permeable web and absorbent layer and fastened to the permeable web. Further, at least a portion of the folded-over portion is elasticized at a distance spaced from the absorbent material such that when the elastic contracts, the pad bows with the elasticized fold raising above the surface of the pad to form a baffle. This results in a dual baffle structure wherein the lower baffle is formed over the absorbent and also an upstanding baffle containing the elastic is formed that extends above the surface of the pad.
Claims11
A generally rectangular bowed absorbent pad comprising an impervious backing sheet, an inner generally rectangular absorbent layer and a body-side permeable web wherein said impervious backing extends beyond the long sides of said rectangular absorbent layer and is folded back on each side and adhered to said permeable web, and wherein elastic members in extended condition are adhered within the folds of said impervious sheet, wherein said impervious sheet is adhered to itself in the area of the folds between said elastic members and said absorbent, said bowed pad has a bowed length of between about 6.5 and about 12 inches and a bowed height of between about 2 and about 3.5 inches, wherein a lower baffle is formed where said backing sheet is adhered to said permeable web, wherein when said elastic contracts the folded impervious sheet forms an upstanding baffle that extends between about 0.5 and about 1.5 inches above the absorbent pad and wherein said elastic extends substantially the entire length of said pad.
