Sanitary napkin pad liner

Claim 2

A napkin liner for use in conjunction with a sanitary protection product comprising: a substantially non-wettable, fluid permeable cover of hydrophobic material located on the body-facing side of the liner; a thin layer of absorbent material for transmitting body fluids which have passed through the cover material to an underlying sanitary protection product; adhesive means, located on the sanitary protection product facing side of said liner, for attaching said liner to an underlying sanitary protection product, said adhesive means posing a relatively insubstantial barrier to the transmission of body fluids through said liner to an underlying absorbent product; and release strip means for covering said adhesive means to prevent inadvertent adhesion of said liner prior to use.

Claim 3

The napkin liner of claim 1, wherein said liner is embossed with a pattern.

Claim 4

The napkin liner of claim 2, wherein said embossed pattern comprises a central, longitudinal channel.

Claim 5

The napkin liner of claim 3, wherein said central, longitudinal channel has a width of approximately one-half inch.

Claim 6

The napkin liner of claim 2, wherein said embossed pattern comprises a snowflake-like pattern evenly distributed over the surface of said cover.

Claim 7

The napkin liner of claim 2, wherein said embossed pattern comprises an hourglass-shaped channel.

Claim 8

The napkin liner of claim 6, wherein the surface of said cover surrounding said hourglass-shaped channel is embossed with a snowflake-like pattern.

Claim 9

The napkin liner of claim 2, wherein said embossed pattern comprises two longitudinal channels respectively offset on either side of the longitudinal center line of said liner.

Claim 10

The napkin liner of claim 1, wherein said adhesive means comprises two lines of pressure-sensitive adhesive locate along the longitudinal edges of said layer of absorbent material so as to pose a relatively insubstantial barrier to the transmission of body fluids through the center of said liner.

Claim 11

The napkin liner of claim 9, wherein said adhesive lines are one-half inch in width or less so as to pose a relatively insubstantial barrier to the transmission of body fluids through the center of said liner.

Claim 12

The napkin liner of claims 1, wherein said cover material comprises a thermally bondable material and said thin layer includes thermally bondable fibers, wherein said cover is thermally bonded to said thin layer about the periphery of said liner.

Claim 13

The napkin liner of claim 11, wherein said thin layer comprises a low density mixture of absorbent fibers and conjugate fibers.

Claim 14

The napkin liner of claim 12, wherein said thin layer comprises a thermally bonded nonwoven fabric, and further includes non-wettable polymeric fibers for maintaining the loft of said fabric.

Claim 15

The napkin liner of claim 13, wherein said fabric comprises two layers of a 2.0 oz./yd. 2 nonwoven.

Claim 16

A napkin liner for use in conjunction with a sanitary protection product comprising: a substantially non-wettable, fluid permeable cover of hydrophobic material located on the body-facing side of the liner; a thin layer of absorbent material for transmitting body fluids which have passed through the cover material to an underlying sanitary protection product; adhesive means, located on the sanitary protection product facing side of said liner, for attaching said liner to an underlying sanitary protection product, said adhesive means posing a relatively insubstantial barrier to the transmission of body fluids through said liner to an underlying absorbent product; and release strip means for covering said adhesive means to prevent inadvertent adhesion of said liner prior to use; wherein the longitudinal edges of said cover material overwrap the longitudinal sides of said liner and the longitudinal edges of the sanitary protection protection product facing side of said layer of absorbent material; and wherein said adhesive means comprises two lines of pressure sensitive adhesive located along the overwrapped longitudinal edges of said cover material on the sanitary protection product facing side of said layer of absorbent material.

Claim 17

A napkin liner for use in conjunction with a sanitary protection product comprising: a substantially non-wettable, fluid permeable cover of hydrophobic material located on the body-facing side of the liner; a thin layer of absorbent material for transmitting body fluids which have passed through the cover material to an underlying sanitary protection product; adhesive means, located on the sanitary protection product facing side of said liner, for attaching said liner to an underlying sanitary protection product, said adhesive means posing a relatively insubstantial barrier to the transmission of body fluids through said liner to an underlying absorbent product; and release strip means for covering said adhesive means to prevent inadvertent adhesion of said liner prior to use; wherein the longitudinal edges of said cover material overwrap the longitudinal sides of said liner and the longitudinal edges of the sanitary protection protection product facing side of said layer of absorbent material; and wherein said adhesive means comprises two lines of pressure sensitive adhesive located along the overwrapped longitudinal edges of said cover material on the sanitary protection product facing side of said layer of absorbent material.

Claim 18

The napkin liner of claim 15, wherein said adhesive means further comprises means for adhering the overwrapped longitudinal edges of said cover material to the sanity protection product facing side of said layer of absorbent material.
