Abstract
Abstract A combination sanitary napkin and interlabial pad is provided by forming an absorbent layer which tapers at one end and folding the layer over on itself to form a double layer with the top layer designed, due to its reduced width, to engage the labia of the user. The upper layer is moveable with respect to the bottom absorbent layer.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
115 words
A combination sanitary napkin and interlabial pad comprising: (a) a unitary absorbent including, (1) a lower absorbent layer; (2) a bridge extending upwardly arcuately from said lower absorbent layer; (3) an upper absorbent layer forming the interlabial pad portion overlying at least a portion of said lower absorbent layer with said upper layer forming a continuation layer and tapering from the wider portion adjacent said bridge to a leading narrower edge distal from said bridge, said upper absorbent layer being moveable with respect to said lower absorbent layer thereby changing the size relationship between said layers; (b) a fluid impermeable baffle positioned on the portion of the lower absorbent layer opposite the upper absorbent layer.
Claim 2
Dependent Claim
115 words
A combination sanitary napkin and interlabial pad comprising: (a) a unitary absorbent including, (1) a lower absorbent layer; (2) a bridge extending upwardly arcuately from said lower absorbent layer; (3) an upper absorbent layer forming the interlabial pad portion overlying at least a portion of said lower absorbent layer with said upper layer forming a continuation layer and tapering from the wider portion adjacent said bridge to a leading narrower edge distal from said bridge, said upper absorbent layer being moveable with respect to said lower absorbent layer thereby changing the size relationship between said layers; (b) a fluid impermeable baffle positioned on the portion of the lower absorbent layer opposite the upper absorbent layer.
Claim 3
Dependent Claim
29 words
The napkin according to claim 1 wherein a fluid pervious wrap overlies the upper and lower surfaces of each layer and the inner and outer portions of the bridge.
Claim 4
Dependent Claim
12 words
The napkin according to claim 1 wherein the upper layer is wedge-shaped.
Claim 5
Dependent Claim
14 words
The napkin of claim 1 wherein said absorbent is covered with a permeable sheet.
Claim 6

The napkin of claim 1 wherein the area of said upper absorbent layer is less than that of the lower absorbent layer.
Claim 7
Dependent Claim
9 words
The napkin of claim 1 comprising only one bridge.
Claim 8
Dependent Claim
18 words
The napkin of claim 1 wherein said fluid impermeable baffle extends along the garment-facing side of said napkin.
Claim 9

17 words
The napkin of claim 1 wherein said upper absorbent layer is not provided with a fluid-impermeable baffle.
Claim 10
Dependent Claim
11 words
The napkin of claim 1 wherein said bridge comprises folded absorbent.
Claim 11

20 words
The napkin of claim 1 wherein said narrower leading edge distal from the bridge is designed to engage the labia.
Claim 12
Dependent Claim
23 words
The napkin of claim 1 wherein said lower absorbent layer and upper absorbent layer comprise a single-absorbent layer which is folded upon itself.
Claim 13
Independent Claim
120 words
A method for making a combination sanitary napkin and interlabial pad comprising: (a) positioning a baffle on a defined portion of an absorbent batt said batt generally decreasing in width from one end to the other; (b) overwrapping said absorbent layer with a fluid pervious wrap; (c) folding said absorbent batt such that the end of decreased width forms an upper absorbent layer movable with respect to the lower absorbent layer, and smaller in area than said lower absorbent layer which is the remainder of said batt with said baffle being positioned on the bottom of said lower absorbent layer wherein said upper absorbent layer decreases in width from the fold to the distal end of said upper absorbent layer.
Claim 14
Independent Claim
120 words
A method for making a combination sanitary napkin and interlabial pad comprising: (a) positioning a baffle on a defined portion of an absorbent batt said batt generally decreasing in width from one end to the other; (b) overwrapping said absorbent layer with a fluid pervious wrap; (c) folding said absorbent batt such that the end of decreased width forms an upper absorbent layer movable with respect to the lower absorbent layer, and smaller in area than said lower absorbent layer which is the remainder of said batt with said baffle being positioned on the bottom of said lower absorbent layer wherein said upper absorbent layer decreases in width from the fold to the distal end of said upper absorbent layer.
Claim 15
Dependent Claim
13 words
The method of claim 12 wherein said folding is on an embossed line.
Claim 16
Dependent Claim
21 words
The method of claim 12 wherein said folding may be adjusted so as to change the size relationship between said layers.
