## Abstract

A sanitary napkin including a plurality of absorbent pad components detachably adhered one to another to form a singular sanitary napkin. Each absorbent pad component formed as a first outer layer, a second centrally disposable layer, and a third layer. Included is a first adhesive strip adapted to detachably adhere a single bottommost of the absorbent pad components to a crotch portion of a feminine undergarment. Also included are additional adhesive strips which affix supplementary absorbent pad components upon the single bottommost of the absorbent pad components. The plurality of absorbent pad components is numerically greater than two. Lastly, an excess of absorbent filler material is included. The excess of absorbent filler material is to enthicken the single bottommost of the absorbent pad components and is capable of enhancing absorption capabilities.

## Claims

### Claim 1

A sanitary napkin with individually disposable absorbent pad components comprising in combination:
at least three substantially elongated absorbent pad components detachably adhered to each other thereby forming a singular sanitary napkin, each absorbent pad component formed of a first, fluid permeable outer layer, a second, centrally disposed, absorbent filler layer, and a third, fluid impermeable layer, each first, fluid permeable outer layer being formed of a polymeric film permitting fluid transfer to the absorbent filler layer, the polymeric film being porous and hydrophobic, each third, fluid impermeable layer comprising a polymeric film, each absorbent pad component having an equal length of about 8 to 10 inches;
each second,centrally disposed, absorbent filler layer being bonded to a top surface of the third layer and the first layer joined to the second and third layers, each second, absorbent filler layer being composed of a thin layer of highly absorbent, low density material formed from a combination of cellulose and cotton;
a first adhesive strip adapted to detachably adhere one of said at least three pad components to a crotch portion of a feminine undergarment, the first adhesive strip linearly positioned along the third layer of said one pad component and covering about 25 percent of a bottom surface thereof, a cover strip overlaying the adhesive strip of said one pad component and being releasable prior to placement of said one pad component;
additional adhesive strips detachably affixing the remainer of said at least three absorbent pad components stacked upon said one pad component, the additional adhesive strips covering 10 percent of a bottom portion of the third layer of each of the remaining absorbent pad components; and
said one pad component including an additional amount of highly absorbent, low density material in its second layer, the additional amount of material contained within said one pad component pad being about fifty percent greater than an amount of absorbent material of the respective second layers of one of the remaining absorbent pad components, the additional amount of material being capable of enhancing absorption capabilities.
