Abstract

A disposable shield for garment protection and everyday feminine hygiene including odor control comprising a very thin, lightweight, highly absorbent structure is disclosed. The shield is soft, rattle-free, supple and easily comformable to the body and the garment and can be securely positioned to the crotch section of a panty or other undergarment.

Claims

1. A disposable shield for everyday feminine hygiene and garment protection comprising a thin, elongate, highly absorbent pad having (a) a porous, substantially planar hydrophobic polymeric body-contacting surface having a soft, doe-skin like hand, (b) an absorptive portion having differential wetting characteristics from one surface to the other to thus provide for controlled movement of fluid away from the bodycontacting surface, (c) a soft, pliable, rattle-free, body fluid-impermeable barrier and (d) an adhesive positioner means comprising substantially the entire garment-contacting surface, said shield being adapted for attachment to a garment such that the shield will not dislodge, shift or move during wear but is removable from the garment without fabric damage or adhesive residue.

2. A disposable shield according to claim 1 wherein said body-contacting surface is the uppermost surface of a lightweight nonwoven web of hydrophobic, thermoplastic fibers unified with a resinous fiber-binding resin.

3. A disposable shield according to claim 1 wherein the absorptive portion comprises a web of 1:

1 blend of polyester staple fibers and cotton staple fibers.

4. A disposable shield according to claim 1 wherein the absorptive portion comprises a web of a 1:

1 blend of polyester staple fiber and cotton staple fibers, to which is added a small amount to highly absorbent fluid immobilizing fibers.

5. A disposable shield according to claim 2 wherein the absorptive portion comprises a web of a 20:

80 spatially controlled blend of polyester staple fibers and bleached sulfite kraft paper fluff, the uppermost surface of said web being predominantly hydrophobic polyester fibers.

6. A disposable shield according to claim 2 wherein the absorptive portion comprises a web of 20:

80 spatially controlled blend of polyester staple fibers and bleached sulfite kraft paper fluff, to which is added a small amount of highly absorbent fluid immobilizing fibers, the uppermost surface of said web being predominantly hydrophobic polyester fibers.

7. A disposable shield according to claim 2 wherein the absorptive portion comprises a sheet of absorbent tissue having laminated thereto a water-swellable film of a water-immobilizing polyacrylate polymer.

8. A disposable shield according to claim 1 wherein the absorptive portion comprises a sheet fo absorbent tissue to which is affixed a pattern of a highly moisture-absorbent hydrolyzed starch-polyacrylonitrile graft copolymer.

9. A disposable shield according to claim 1 wherein the absorptive portion comprises a patterned layer of a hydrolyzed starch-polyacrylontrile graft copolymer applied onto the body fluid impermeable barrier.

10. A disposable shield according to claim 1 wherein the body fluid-impermeable barrier is moisture vapor-permeable.

11. A disposable shield according to claim 6 wherein the body fluid-impermeable barrier is a web of entangled melt-blown organic polymeric microfibers.

12. A disposable shield according to claim 6 wherein the body fluid-impermeable barrier is a thin layer of a film-forming polymer.

13. A disposable shield according to claim 1 wherein the body fluid-impermeable barrier is a thin foam.

14. A disposable shield according to claim 1 wherein the positioner means comprises a fiber reinforced pressure-sensitive adhesive layer overlying substantially the entire surface of said body fluid-impermeable layer.

15. A disposable shield according to claim 1 wherein the positioner means comprises a nonwoven web unified with a pressure-sensitive adhesive composition.

16. A disposable shield according to claim 1 having a pattern of longitudinally extending line embossments terminating within the periphery of the shield impressed in said body-contacting surface and said absorptive portion to channel fluid toward the ends of the shield.

17. A disposable shield according to claim 1 having an antimicrobial agent incorporated into the absorptive thereof.

18. A disposable shield according to claim 1 having a malodor counteractant incorporated into the absorptive layer thereof.

19. A disposable shield for everyday feminine hygiene and garment protection comprising a thin, elongate, highly absorbent pad having:

a. a porous, substantially planar bodycontacting surface having a soft doe-skin like hand,

said surface being the uppermost surface of said pad unified with a hydrophobic resinous fiber binding resin;

b. an absorptive portion comprising a lofty web of a 1;

1 blend of polyester staple fibers and cotton staple fibers having differential wetting characteristics from one surface to the other to thus provide for controlled movement of fluid away from the body-contacting surface.

said absorptive portion having an antimicrobial agent and a malodor counteractant incorporated therein;

c. a thin, soft, pliable, rattle-free, moisture vapor-permeable but body fluid-impermeable barrier,

said barrier being a thin layer of a film-forming polymer,

d. an adhesive positioner means overlying said barrier and comprising substantially the entire garment contacting surface,

said positioner means being a fiber-reinforced pressure-sensitive adhesive layer;

e. a pattern of longitudinally extending line embossments terminating within the periphery of the shield impressed in said body-contacting surface and said absorptive portion to channel fluid toward the ends of the shield,

said shield being adapted for attachment to a garment such that the shield will not dislodge, shift or move during wear but is removable from the garment without fabric damage or adhesive residue.

20. A disposable shield for everyday feminine hygiene and garment protection comprising a thin, elongate, highly absorbent pad having:

a. a porous, substantially planar body-contacting surface having a soft doe-skin like hand,

said surface being the uppermost surface of a lightweight nonwoven web of hydrophobic, thermoplastic fibers unified with a hydrophobic resinous fiber binding resin;

b. an absorptive portion comprising a lofty web of a 20;

80 spatially controlled blend of polyester staple fibers and bleached sulfite kraft paper fluff, the top surface of said web being predominantly hydrophobic polyester fibers, said web having differential wetting characteristics from one surface to other to thus provide for controlled movement of fluid away from the body contacting surface,

said absorptive portion having an antimicrobial agent and a malodor counteractant incorporated therein;

c. a thin, soft, pliable, rattle-free, moisture vapor-permeable but body fluid-impermeable barrier,

said barrier being a thin web of entangled melt-blown organic polymeric microfibers;

d. an adhesive positioner means overlying said barrier and comprising substantially the entire garment contacting surface,

said positioner means being a nonwoven web unified with a pressure-sensitive adhesive compositions; and

e. a pattern of longitudinally extending line embossments terminating within the periphery of the shield impressed in said body-contacting surface and said sbsorptive portion to channel fluid toward the ends of the shield,

said shield being adapted for attachment to a garment such that the shield will not dislodge, shift or move during wear but is removable from the garment without fabric damage or adhesive residue.
