## CPC

- A61F 13/208: {having means for avoiding leakage, e.g. liquid impermeable withdrawal end (A61F13/204 takes precedence)}
- A61F 13/34: Means for withdrawing tampons {, e.g. withdrawal strings}
- A61F: FILTERS IMPLANTABLE INTO BLOOD VESSELS; PROSTHESES; DEVICES PROVIDING PATENCY TO, OR PREVENTING COLLAPSING OF, TUBULAR STRUCTURES OF THE BODY, e.g. STENTS; ORTHOPAEDIC, NURSING OR CONTRACEPTIVE DEVICES; FOMENTATION; TREATMENT OR PROTECTION OF EYES OR EARS; BANDAGES, DRESSINGS OR ABSORBENT PADS; FIRST-AID KITS (dental prosthetics A61C)

## Abstract

A tampon (1) having a nonpermeable cap (5) is placed over a distal end (4) of the tampon. The nonpermeable cap has a tubular wall (6) that surrounds the distal end of the tampon and rests inside the vagina (15). The tubular wall is pushed outward against the walls (16) of the vagina as the tampon expands with the absorption of fluid. The nonpermeable cap prevents liquids from escaping from the vagina or outside fluids being absorbed by the distal end of the tampon and into the vagina.

## Claims

### Claim 1

A tampon comprising:
a substantially cylindrically-shaped main body constructed from an absorbent material;
said main body having a proximal end and a distal end;
a nonpermeable cap having a tubular wall and an end wall; and
said nonpermeable cap being placed over the distal end of the main body so the tubular wall of the nonpermeable cap surrounds the distal end of the main body to prevent the leakage of fluids through the distal end of the main body.

### Claim 2 (depends on 1)

The tampon of claim 1 further comprising:
an attachment means to secure the nonpermeable cap to the absorbent material of the main body to prevent any separation of the nonpermeable cap from the main body of the tampon.

### Claim 3 (depends on 1)

The tampon of claim 1 wherein:
an upper perimeter edge of the tubular wall of the nonpermeable cap is angled inward against the main body of the tampon to prevent any separation of the nonpermeable cap from the main body of the tampon.

### Claim 4 (depends on 1)

The tampon of claim 1 further comprising:
a removal aid located on the nonpermeable cap to assist a female in removing the tampon from the vagina.

### Claim 5 (depends on 4)

The tampon of claim 4 wherein:
the removal aid is separated from the main body of the tampon by the nonpermeable cap.

### Claim 6 (depends on 4)

The tampon of claim 4 wherein:
the removal aid is an extension.

### Claim 7 (depends on 4)

The tampon of claim 4 wherein:
the removal aid is a nipple.

### Claim 8

A tampon comprising:
a substantially cylindrically-shaped main body constructed from an absorbent material;
said main body having a proximal end and a distal end;
a nonpermeable cap having a tubular wall and an end wall;
said nonpermeable cap being placed over the distal end of the main body so the tubular wall of the nonpermeable cap surrounds the distal end of the main body to prevent the leakage of fluids through the distal end of the main body; and
an upper perimeter edge of the tubular wall of the nonpermeable cap is angled inward against the main body of the tampon to prevent any separation of the nonpermeable cap from the main body of the tampon.

### Claim 9 (depends on 8)

The tampon of claim 8 further comprising:
an attachment means to secure the nonpermeable cap to the absorbent material of the main body to prevent any separation of the nonpermeable cap from the main body of the tampon.

### Claim 10 (depends on 8)

The tampon of claim 8 further comprising:
a removal aid located on the nonpermeable cap to assist a female in removing the tampon from the vagina.

### Claim 11 (depends on 10)

The tampon of claim 10 wherein:
the removal aid is separated from the main body of the tampon by the nonpermeable cap.

### Claim 12 (depends on 10)

The tampon of claim 10 wherein:
the removal aid is an extension.

### Claim 13 (depends on 10)

The tampon of claim 10 wherein:
the removal aid is a nipple.

### Claim 14

A tampon comprising:
a substantially cylindrically-shaped main body constructed from an absorbent material;
said main body having a proximal end and a distal end;
a nonpermeable cap having a tubular wall and an end wall;
said nonpermeable cap being placed over the distal end of the main body so the tubular wall of the nonpermeable cap surrounds the distal end of the main body to prevent the leakage of fluids through the distal end of the main body; and
a removal aid located on the nonpermeable cap to assist a female in removing the tampon from the vagina.

### Claim 15 (depends on 14)

The tampon of claim 14 further comprising:
an attachment means to secure the nonpermeable cap to the absorbent material of the main body to prevent any separation of the nonpermeable cap from the main body of the tampon.

### Claim 16 (depends on 14)

The tampon of claim 14 wherein:
an upper perimeter edge of the tubular wall of the nonpermeable cap is angled inward against the main body of the tampon to prevent any separation of the nonpermeable cap from the main body of the tampon.

### Claim 17 (depends on 14)

The tampon of claim 14 wherein:
the removal aid is separated from the main body of the tampon by the nonpermeable cap.

### Claim 18 (depends on 14)

The tampon of claim 14 wherein:
the removal aid is an extension.

### Claim 19 (depends on 14)

The tampon of claim 14 wherein:
the removal aid is a nipple.
