Abstract

Abstract A protective liner which is temporarily, but securely, held to the interior crotch portion of nether gr garments by doublefaced, pressure sensitive adhesive labels provided on the under surface of the liner. The adhesive label possesses differential adhesion levels such that the adhesive layer that secures the label to the protective liner possesses a greater level of adhesion so as to permanently adhere the label thereto, than does the adhesive layer of the label that temporarily, but securely, adheres the label and the liner to the crotch portion of the nether garment.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 275 words
A protective absorbent liner for nether garments comprising: a. a core of absorbent material; b. a fluid pervious cover overlying the top surface and the side edges of said core; c. a fluid impervious barrier sheet secured to and overlying the bottom surface of said core; 1. the lateral edges of said fluid pervious cover being spaced apart on the bottom surface of said core and sandwiched between said core and said barrier sheet in secured relationship therewith, and 2. the end margins of said cover and said barrier sheet being secured to one another in face-to-face relationship beyond the end edges of said core; and d. adhesive means positioned on the bottom of said liner for temporarily, but securely, adhering said liner to the interior of the crotch portion of a nether garment; 1. said attachment means comprising: a. a double-faced pressure sensitive adhesive label having a differential level of adhesion by the adhesive layer of the first face of said label having a level of adhesion ranging from about 30 to about 112 ounces/inch width and the adhesive layer of the second face of said label having a level of adhesion ranging from about 20 to about 49 ounces/inch width, b. the ratio between the levels of adhesion of the layer of adhesive of said second face ranging from about 1.5:1 to about 2.5:1, and c. the adhesive layer of said first face permanently adhering said label to said barrier sheet and the adhesive layer of said second face temporarily, but securely, adhering said label and said liner to the interior crotch portion of said nether garment when said liner is being worn.
Claim 2
Dependent Claim 275 words
A protective absorbent liner for nether garments comprising: a. a core of absorbent material; b. a fluid pervious cover overlying the top surface and the side edges of said core; c. a fluid impervious barrier sheet secured to and overlying the bottom surface of said core; 1. the lateral edges of said fluid pervious cover being spaced apart on the bottom surface of said core and sandwiched between said core and said barrier sheet in secured relationship therewith, and 2. the end margins of said cover and said barrier sheet being secured to one another in face-to-face relationship beyond the end edges of said core; and d. adhesive means positioned on the bottom of said liner for temporarily, but securely, adhering said liner to the interior of the crotch portion of a nether garment; 1. said attachment means comprising: a. a double-faced pressure sensitive adhesive label having a differential level of adhesion by the adhesive layer of the first face of said label having a level of adhesion ranging from about 30 to about 112 ounces/inch width and the adhesive layer of the second face of said label having a level of adhesion ranging from about 20 to about 49 ounces/inch width, b. the ratio between the levels of adhesion of the layer of adhesive of said second face ranging from about 1.5:1 to about 2.5:1, and c. the adhesive layer of said first face permanently adhering said label to said barrier sheet and the adhesive layer of said second face temporarily, but securely, adhering said label and said liner to the interior crotch portion of said nether garment when said liner is being worn.
Claim 3
Dependent Claim 54 words
the end margins of said cover and said barrier sheet being secured to one another in face-to-face relationship beyond the end edges of said core; and d. adhesive means positioned on the bottom of said liner for temporarily, but securely, adhering said liner to the interior of the crotch portion of a nether garment;
Claim 4
Dependent Claim 54 words
the end margins of said cover and said barrier sheet being secured to one another in face-to-face relationship beyond the end edges of said core; and d. adhesive means positioned on the bottom of said liner for temporarily, but securely, adhering said liner to the interior of the crotch portion of a nether garment;
Claim 5
Dependent Claim 29 words
The protective absorbent liner of claim 1 wherein the adhesive layer of said second face is protected by a removable release strip when said liner is not in use.
Claim 6
Dependent Claim 83 words
The protective absorbent liner of claim 1 wherein the adhesive layer of said first face has a level of adhesion ranging from about 60 to about 68 ounces/inch width and the adhesive layer of said second face has a level of adhesion ranging from about 32 to about 37 ounces/inch width and the ratio between the adhesion levels of the layer of adhesive of said first face and the layer of adhesive of said second face ranges from about 1.9:1 to about 2.1:1.
Claim 7
Dependent Claim 40 words
The protective absorbent liner of claim 1 wherein the adhesive layer of said first face and the adhesive layer of said second face are chemically different, incompatible adhesive masses and are separated from one another by a pervious substrate film.
Claim 8
Dependent Claim 40 words
The protective absorbent liner of claim 1 wherein the adhesive layer of said first face and the adhesive layer of said second face are chemically different, incompatible adhesive masses and are separated from one another by an impervious substrate film.
Claim 9
Dependent Claim 39 words
The protective absorbent liner of claim 1 wherein the adhesive layer of said first face and the adhesive layer of said second face are chemically similar adhesive masses and are separated from one another by an impervious substrate film.
Claim 10
Dependent Claim 28 words
The protective absorbent liner of claim 1 wherein the adhesive layer of said first face is of greater surface area than the adhesive layer of said second face.
Claim 11
