Abstract

Nail polish remover strips are pre-sized for toe or fingernails and applied to a painted or artificial nail and left thereon for a predetermined period of time to dissolve the nail polish and/or nail bonding agent. Preferably a color change occurs to depict the appropriate dwelling time to dissolve the nail polish. Certain embodiments include odor reducing components. Preferably the strips are layered composites having an exterior odor impervious material, a layer of encapsulated acetone or nail polish removing agent, an absorbent layer, and a peelable backing, with the strips being sized to accommodate contact with a person'"'"'s nail.

Claims

1. An insect repellent layered strip, consisting of:

four layers, with a first layer comprising an odor impervious material, a second layer that comprises at least one encapsulated solvent comprising N,N-diethyl-m-toluamide (DEET), a third layer having a solvent absorbent material in the form of a pad, and a fourth layer comprising an adhesive and having a peelable backing, wherein the solvent is encapsulated in a frangible enclosure and is present in an amount of at least about 0.5 ml, and wherein the breakage of the frangible enclosure releases a fresh supply of said solvent onto said pad for the passive evaporation of said solvent.

2. The insect repellent layered strip as set forth in claim 1, wherein said solvent includes a color change indicator.

3. The insect repellent layered strip as set forth in claim 1, wherein said frangible enclosure is attached to the solvent absorbent material.

4. The insect repellent layered strip as set forth in claim 1, wherein the frangible enclosure comprises polytetrafluoroethylene.

5. The insect repellant layered strip as set forth in claim 1, further comprising an additional encapsulated solvent selected from the group consisting of acetone and dihydronepetalactone.

6. The insect repellent layered strip as set forth in claim 1, further including at least one of an odor reducer and a color change agent.

7. The insect repellent layered strip as set forth in claim 1, wherein said solvent absorbent material comprises non-woven fabrics.

8. The insect repellent layered strip as set forth in claim 1, wherein the frangible enclosure has a hollow interior that defines a reservoir for containing in addition to said solvent, a color change material, and an odor reducing agent comprising hydroxypropyl beta-cyclodextrin.

9. The insect repellent layered strip as set forth in claim 1, wherein said frangible enclosure comprises a capsule that contains more than one substance.

10. The insect repellent layered strip as set forth in claim 1, wherein said first layer forms a barrier between the solvent and the skin of a user.

11. The insect repellent layered strip as set forth in claim 1, wherein the insect repellent layered strip is adapted to be placed on a person'"'"'s body in a manner such that the second layer and the third layer are adjacent to each other and the fourth layer is adjacent said person'"'"'s body.

12. The insect repellent layered strip as set forth in claim 1, further comprising an odor reducing agent comprising hydroxypropyl beta-cyclodextrin.

13. The insect repellent layered strip as set forth in claim 1, wherein the solvent absorbent layered strip has the second layer and the third layer adjacent to each other and the fourth layer is adjacent the first layer.

14. An insect repellent layered strip, consisting of:

four layers, with a first layer that comprises an odor impervious material, a second layer that comprises an encapsulated solvent comprising N,N-diethyl-m-toluamide, a third layer in the form of a pad having a solvent absorbent material comprising non-woven fabrics and a fourth layer comprising an adhesive and having a peelable backing;

wherein the encapsulated solvent is contained within a frangible enclosure comprised of polytetrafluoroethylene and wherein said first layer forms a barrier between the solvent and the skin of a user, and wherein the breakage of the frangible enclosure releases a fresh supply of said solvent onto said pad for the passive evaporation of said solvent.

15. An insect repellent layered strip, consisting of:

four layers, with a first layer comprising an odor impervious material, a second layer that comprises at least one encapsulated solvent comprising N,N-diethyl-m-toluamide, a third layer in the form of a pad having a solvent absorbent material comprising non-woven fabrics positioned directly on top of the first layer, and a fourth layer comprising an adhesive and having a peelable backing, wherein the solvent is encapsulated in a frangible enclosure comprising polytetrafluoroethylene, said solvent being present in an amount of at least about 0.5 ml, said frangible enclosure attached to the solvent absorbent material, wherein the frangible enclosure has a hollow interior that defines a reservoir for containing, in addition to said solvent, one of an odor reducing agent comprising hydroxypropyl beta-cyclodextrin and a color change agent, wherein when the frangible enclosure is broken, the at least one encapsulated solvent soaks the solvent absorbent material on top of the odor impervious material to vaporize the at least about 0.5 ml. of said solvent into the air surrounding the strip, and wherein the breakage of the frangible enclosure releases a fresh supply of said solvent onto said pad for the passive evaporation of said solvent.

16. An insect repellent layered strip, consisting of:

four layers, with a first layer comprising an odor impervious material, a second layer that comprises an encapsulated solvent comprising N,N-diethyl-m-toluamide (DEET), a third layer in the form of a pad having a solvent absorbent material comprising non-woven fabrics, and a fourth layer comprising an adhesive and having a peelable backing, wherein the solvent is encapsulated in a frangible enclosure comprising polytetrafluoroethylene, said solvent being present in an amount of at least about 0.5 ml, said frangible enclosure attached to the solvent absorbent material, wherein the frangible enclosure has a hollow interior that defines a reservoir for containing, in addition to said solvent, an odor reducing agent comprising hydroxypropyl beta-cyclodextrin, wherein said solvent absorbent material retains the DEET by soaking the solvent absorbent material, thereby providing insect repellent protection due to vapors evolving from the soaked solvent absorbent material, the solvent permitted to directly evaporate from the soaked solvent absorbent material into a surrounding atmosphere of the air surrounding said strip, and wherein the breakage of the frangible enclosure releases a fresh supply of said solvent onto said pad for the passive evaporation of said solvent.
