Abstract

A finger tip enclosure apparatus for fitting over and sealingly enclosing a user finger tip and its fingernail includes an enclosure shell having a tubular shell side wall with a side wall proximal end and a side wall distal end, the side wall proximal end including a sealing structure protruding radially inward for making circumferential sealing contact with side surfaces of a human finger, the side wall distal end being sealingly joined to and closed by a distal end wall. The apparatus may retain a fingernail polish solvent in prolonged contact with the fingernail so that polish on the fingernail is dissolved or softened for removal while freeing the to move about and perform manual tasks, and alternatively may retain medication in prolonged contact with the finger tip and fingernail, and still alternatively may shield the finger tip and fingernail from contamination and abrasion.

Claims

1. A fingertip enclosure apparatus for fitting over and sealingly enclosing a user finger tip and its fingernail for use with a solvent solution to remove nail polish from the fingernail, the apparatus comprising:

an enclosure shell having a tubular shell side wall with a side wall proximal end and a side wall distal end defining a finger receiving interior space adapted to retain the solvent solution about the finger tip and fingernail, said side wall proximal end including a sealing structure protruding radially inward for making circumferential sealing contact with side surfaces of the finger tip, said side wall distal end being sealingly joined to and closed by a distal end wall, said enclosure shell which includes a bulge protruding radially outward as part of said side wall to define a fingernail chamber in said interior space positionable directly adjacent the fingernail which is adapted to retain additional solvent solution on the fingernail when the finger tip is in said interior space to facilitate removal of the nail polish.

2. The finger tip enclosure apparatus of claim 1, wherein said sealing structure is chosen from the group consisting of a solid rib and a circumferential undulation in said side wall.

3. The finger tip enclosure apparatus of claim 1, wherein said side wall includes at least one internal support rib for strengthening said enclosure shell.

4. The finger tip enclosure apparatus of claim 1, wherein said bulge protrudes distally outward as part of said distal end wall to receive a long user fingernail which extends beyond the finger tip.

5. The finger tip enclosure apparatus of claim 1, wherein said apparatus includes at least one abrasion element which extends into the fingernail chamber closely adjacent the fingernail adapted wherein the user can apply pressure radially inwardly against said side wall to press the abrasion elements into contact with the nail polish softened by the solvent solution and rub the abrasion elements thereagainst to dislodge the nail polish.

6. The finger tip enclosure apparatus of claim 5, wherein the enclosure shell includes an external finger engaging ramp portion to facilitate the user applying pressure radially inwardly against said side wall to press the abrasion elements into contact with the nail polish.

7. A fingertip enclosure apparatus for fitting over and sealingly enclosing a user finger tip and its fingernail, the apparatus comprising:

an enclosure shell having a tubular shell side wall with a side wall proximal end and a side wall distal end, said side wall proximal end including a sealing structure protruding radially inward for making circumferential sealing contact with side surfaces of a human finger, said side wall distal end being sealingly joined to and closed by a distal end wall;

wherein said enclosure shell encloses an interior space and wherein said interior space is at least partly filled with a solution said apparatus additionally comprising a sealing membrane extending across said interior space within said enclosure shell retaining said solvent;

such that when a user fits a finger tip into said proximal end, the finger tip bears against and ruptures said sealing membrane and then enters, said interior space and is immersed in the solution, while side surfaces of the user finger simultaneously make sealing contact with said sealing structure.

8. The finger tip enclosure apparatus of claim 7, wherein the enclosure shell includes a circumferential membrane abutment rib adapted for mounting the sealing membrane, said sealing membrane abutting said membrane abutment rib for strengthened membrane mounting by sealingly bonding said membrane to said membrane abutment rib.

9. The finger tip enclosure apparatus of claim 7, wherein the solution has a gel consistency for resisting accidental spilling and spraying as the finger tip and fingernail are inserted thereinto.

10. A finger tip enclosure apparatus for fitting over and sealingly enclosing a user finger tip and its fingernail, the apparatus comprising:

an enclosure shell having a tubular shell side wall with a side wall proximal end and a side wall distal end, said side wall proximal end including a sealing structure for making circumferential sealing contact with side surfaces of a human finger, said side wall distal end being sealingly joined to and closed by a distal end wall;

additionally comprising;

a pad slot in said side wall;

and a solvent absorbing pad secured across and closing said pad slot;

such that a solution deposited onto said absorbent pad is absorbed and transmitted through said absorbent pad and thereby delivered into contact with a user finger within said enclosure shell.

11. The finger tip enclosure apparatus of claim 10, wherein said absorbent pad is impregnated with an abrasive material.

12. The finger tip enclosure apparatus of claims 10, wherein said absorbent pad has pad mounting periphery which protrudes beyond said pad slot and overlaps said side wall, and has pad adhesive on said pad mounting periphery securing said absorbent pad to said side wall as said absorbent pad extends over and closes over said pad slot.

13. The finger tip enclosure apparatus of claim 12, wherein said absorbent pad comprises:

an absorbent pad outward surface and an absorbent pad inward surface;

a solvent permeable backing sheet bonded to said absorbent pad outward surface and extending laterally to define said pad mounting periphery;

and a peel away cover sheet secured to said pad inward surface with a light adhesive to be removable from said absorbent pad when said apparatus is to be used.

14. The finger tip enclosure apparatus of claim 10, Wherein said absorbent pad comprises an abrasive element for dislodging polish from a fingernail within said enclosure shell.

15. The finger tip enclosure apparatus of claim 10, wherein said enclosure shell includes a bulge protruding radially outwardly as part of said side wall having the pad slot therethrough to define a fingernail chamber in said interior space adapted to receive the pad.

16. The finger tip enclosure apparatus of claim 15, wherein said bulge protrudes distally outward as part of said distal end wall to receive a long user fingernail which extends beyond the finger tip.

17. The finger tip enclosure apparatus of claim 10, wherein said pad slot has a rectangular periphery.
