Abstract
Abstract Methods of making feminine hygienic pads from non-layered and layered material by use of folding, pressure molding and various methods of bonding to create a long geometric form with an anterior leading panel of narrow thickness and a thicker posterior underpanel of a wider thickness. The folded panels may be bonded by either a suitable adhesive, crimping, heat, pressure or ultrasonic means leaving an anterior portion with a leading anterior edge and a larger posterior portion. A filler may be inserted between the folds of the material prior to bonding. Thereafter, the long geometric form is multiple cut transversely providing pads about two inches long. These pads are used for insertion into the female interlabial space. The geometric configuration of the pads facilitates insertion of the pad via the anterior leading edge into the interlabial space and has improved retention within such space.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
173 words
A method of making feminine hygienic pads from a material of predetermined width by folding said material producing opposed longitudinal edge portions and opposed faces, said longitudinal folds providing a folded geometric form, said method including the forming of a first panel by one or more inwardly directed folds of said material of one longitudinal edge portion over one face of said material providing a fold formed anterior leading edge, forming a second panel by one or more inwardly directed folds of the material of the other longitudinal edge portion over one face thereof, folding said second panel across a major portion of the width of the one face and over said first panel to a point short of the anterior leading edge formed during the folding of said first panel, bonding the forward folded edge of said second panel to the underlying material of said first panel inwardly of said anterior leading edge of said first panel to define an anterior portion with a leading anterior edge and a larger posterior portion.
Claim 2
Independent Claim
173 words
A method of making feminine hygienic pads from a material of predetermined width by folding said material producing opposed longitudinal edge portions and opposed faces, said longitudinal folds providing a folded geometric form, said method including the forming of a first panel by one or more inwardly directed folds of said material of one longitudinal edge portion over one face of said material providing a fold formed anterior leading edge, forming a second panel by one or more inwardly directed folds of the material of the other longitudinal edge portion over one face thereof, folding said second panel across a major portion of the width of the one face and over said first panel to a point short of the anterior leading edge formed during the folding of said first panel, bonding the forward folded edge of said second panel to the underlying material of said first panel inwardly of said anterior leading edge of said first panel to define an anterior portion with a leading anterior edge and a larger posterior portion.
Claim 3
Dependent Claim
15 words
The method as in claim 1 wherein said bonding is by means of an adhesive.
Claim 4
Dependent Claim
14 words
The method as in claim 1 wherein said bonding is by means of crimping.
Claim 5
Dependent Claim
14 words
The method as in claim 1 wherein said bonding is by means of heat.
Claim 6
Dependent Claim
14 words
The method as in claim 1 wherein said bonding is by means of pressure.
Claim 7
Dependent Claim
13 words
The method as in claim 1 wherein said bonding is by ultrasonic means.
Claim 8
Dependent Claim
22 words
The method as in claim 1 wherein a filler material is inserted between the folds of the folded material prior to bonding.
Claim 9
Dependent Claim
23 words
The method as in claim 1 including the cutting of said folded material transverse to the folds to provide pads of predetermined length.
Claim 10
Dependent Claim
72 words
A method as in claim 1 wherein a filler material is introduced into folded material whose free edges are joined to create a tubular form containing said filler material wherein the opposed surfaces of the tubular form are then bonded together by ultrasonic means at a point near one of the edges of the tubular form to create a long geometric form with an anterior leading edge and a larger posterior portion.
Claim 11
Dependent Claim
29 words
