Abstract
An elastic sided curved absorbent pad is provided with soft side edges providing efficient leakage protection without irritation. The pad has elasticized side panels which comprise at least two layers of non-woven material mounted between a cover and baffle, projecting beyond the side edges of the cover and the baffle, giving the panel soft, free outer distal edges and one or more elastic members inboard from the free distal edge. The layers of non-woven material and the elastic member are bonded together, except for the distal edges which are not bonded. This provides a lace-like appearance and feel.
Claims23
An elastic-sided absorbent pad comprising:
- a) a liquid permeable cover having a bodyside surface, an absorbent-core-side surface opposite said bodyside surface, opposite front and back ends and opposite side edge margins extending to respective side edges;
- b) a liquid impermeable baffle having an absorbent-core-side surface, a garment-side surface opposite said absorbent-core-side surface, opposite front and back ends and opposite side edge margins extending to respective side edges, wherein the side edge margins of said cover and said baffle are bonded except for portions within at least about 0.5 millimeter of said respective side edges thereby forming free distal edges;
- c) an absorbent core positioned between the cover and the baffle, said absorbent core having a pair of side edges;
- d) a pair of shirred elasticized side panels, each operatively positioned between the cover and the baffle, extending outwardly from and along each side edge of said absorbent core and projecting at least about one millimeter beyond the respective side edge margins of the cover and the baffle thereby having a free distal edge, each elasticized side panel comprising at least two layers of non-woven material having a fiber density less than about 0.036 gram per cubic centimeter and at least one elastic member positioned inboard from the free distal edge of the respective panel, wherein said layers of non-woven material and said elastic member are bonded together, except for a portion within at least about 0.5 millimeter of said free distal edge of the respective panel which is not bonded.

An absorbent pad comprising:
- a liquid permeable cover having a bodyside surface, an absorbent-core-side surface opposite said bodyside surface and opposite side edge margins extending to respective side edges of the cover, each of said side edge margins of the cover having an inboard portion spaced at least about 0.5 millimeter from the respective side edge of the cover and an outboard portion extending from the corresponding inboard portion to the respective side edge of the cover;
- a liquid impermeable baffle having an absorbent-core-side surface facing the absorbent-core-side surface of the cover, a garment-side surface opposite said absorbent-core-side surface and opposite side edge margins extending to respective side edges of the baffle, each of said side edge margins of the baffle having an inboard portion spaced at least about 0.5 millimeter from the respective side edge of the baffle and an outboard portion extending from the corresponding inboard portion to the respective side edge of the baffle;
- the inboard portion of each side edge margin of said cover bonded to the corresponding inboard portion of each side edge margin of said baffle;
- the outboard portion of each side edge margin of said cover substantially free from the corresponding outboard portion of each side edge margin of said baffle;
- an absorbent core positioned between the absorbent-core-side surface of the cover and the absorbent-core-side surface of the baffle;
- and
- a pair of side panels, each of said side panel at least partially received between the cover and the baffle along respective side edge margins thereof and extending outward from and projecting at least about one millimeter beyond the respective side edges of the cover and the baffle, the side panels each having opposite ends, the cover and the baffle bonded substantially continuously along a region extending between respective ends of the side panels, the bond at said region free of any intermediate connection to the side panels.
