Abstract
Abstract A sanitary pad, such as a baby diaper, and method for its fabrication. The pad comprises a base panel with an exposed outermost waterproof backing. A central filler pad of multiple layer absorbent material, one of which is highly compressed, is located on the base panel in inwardly spaced relation to the side and end edges of the base panel. Reinforcing strips are overlaid at the ends of the base panel and are laminated thereto. Portions of the strips adjacent the ends of the filler pad are formed into pockets into which the ends of the filler pad fit to anchor the filler in its central location. The reinforcing strips include a plastic ply to provide a barrier to prevent leakage endwise from the pad and function as attaching bands to hold pins, tape, etc., by which the pad is secured in place on the body. The strips also serve to provide a media to make an effective end seal between the several layers of material at the ends of the pad.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
172 words
A sanitary pad comprising a moisture resistant base panel, a central filler spaced inwardly from the side and end edges of the base panel, a cover sheet of moisture transmitting fabric over the top of the filler, longitudinally spaced reinforcing scrim strips at the ends of the base panel, portions of said strips overlapping the ends of said filler comprising pockets into which said filler ends are received, filler and cover portions intermediate their ends being exposed between said strips and portions of said strips spaced from the ends of said filler comprising continuous sealed zones at the ends of the pad, said base panel having side margins wrapped around the filler, said margins having centrally located notches through which the intermediate portions of the top of the cover and filler are exposed and means adhering central portions of said side margins to pad portions therebeneath, leaving end portions wrapped but unattached whereby the central portions of said margins remain wrapped about the filler when end portions of the margins are unwrapped.
Claim 2
Dependent Claim
172 words
A sanitary pad comprising a moisture resistant base panel, a central filler spaced inwardly from the side and end edges of the base panel, a cover sheet of moisture transmitting fabric over the top of the filler, longitudinally spaced reinforcing scrim strips at the ends of the base panel, portions of said strips overlapping the ends of said filler comprising pockets into which said filler ends are received, filler and cover portions intermediate their ends being exposed between said strips and portions of said strips spaced from the ends of said filler comprising continuous sealed zones at the ends of the pad, said base panel having side margins wrapped around the filler, said margins having centrally located notches through which the intermediate portions of the top of the cover and filler are exposed and means adhering central portions of said side margins to pad portions therebeneath, leaving end portions wrapped but unattached whereby the central portions of said margins remain wrapped about the filler when end portions of the margins are unwrapped.
Claim 3
Dependent Claim
30 words
The pad of claim 1 in which said filler comprises a mat of densified filler material adjacent the base panel and a pad of less densely packed filler material thereover.
Claim 4
Dependent Claim
15 words
The pad of claim 2 in which the densified mat has longitudinally extending grooves therein.
Claim 5
Dependent Claim
17 words
The pad of claim 1 in which the reinforcing strips comprise laminates of gauze, tissue and plastic.
Claim 6
Independent Claim
150 words
The method of fabricating a sanitary pad having a base panel, a central filler spaced inwardly from the side and end edges of the base panel and reinforcing strips at the ends of the base panel, portions of said strips adjacent the ends of said filler comprising pockets into which said filler ends are received, said method comprising the steps of depositing a series of fillers in end-to-end spaced relation with gaps therebetween on a continuous strip of base panel material, depositing said reinforcing strips in the gaps between said fillers and in overlapping relation to the ends of adjacent fillers to form pockets for said ends and attaching said reinforcing strips to the base panel, plus the step of folding the side margins of the base panel over the top of the filler and concurrently folding the reinforcing strip over itself and over the pocketed ends of the filler.
Claim 7
Independent Claim
150 words
The method of fabricating a sanitary pad having a base panel, a central filler spaced inwardly from the side and end edges of the base panel and reinforcing strips at the ends of the base panel, portions of said strips adjacent the ends of said filler comprising pockets into which said filler ends are received, said method comprising the steps of depositing a series of fillers in end-to-end spaced relation with gaps therebetween on a continuous strip of base panel material, depositing said reinforcing strips in the gaps between said fillers and in overlapping relation to the ends of adjacent fillers to form pockets for said ends and attaching said reinforcing strips to the base panel, plus the step of folding the side margins of the base panel over the top of the filler and concurrently folding the reinforcing strip over itself and over the pocketed ends of the filler.
Claim 8
Dependent Claim
35 words
The method of claim 5 plus the subsequent step of severing the continuous strip of base panel material and the reinforcing strip through the gap between spaced fillers, thus to create separate discrete sanitary pads.
