Abstract

Claims (43)

1. A method of creating a tampon, the method comprising:

forming an absorbent body defining a cylindrical shape having an exterior surface, a hollow interior, an interior surface, and first and second opposing distal ends, the absorbent body having a fluid absorbent material;

enclosing the absorbent body within a protective sleeve at the exterior surface, interior surface, and both distal ends, the protective sleeve being porous to allow fluid to enter the absorbent body but prevent absorbent body material from passing through the protective sleeve, wherein the absorbent body and protective sleeve combine to define an overall tubular structure having an inner hollow region and a first diameter, wherein enclosing the absorbent body within a protective sleeve includes:

rolling a porous sheet around the absorbent body, wherein the porous sheet extends beyond both distal ends of the absorbent body at a length that exceeds the length of the absorbent body;

pinching together a first distal end of the porous sheet that extends beyond the first distal end of the absorbent body; and

pushing the pinched together first distal end of the porous sheet through the hollow interior and past the second distal end of the absorbent body, wherein the first distal end of the porous sheet and a second distal end of the porous sheet both extend past the second distal end of the absorbent body; and

coupling a string to the protective sleeve, wherein the string facilitates removal of the tampon after use.

2. The method of claim 1 , further comprising the step of:

compressing the overall tubular structure to a second diameter that is less than the first diameter.

3. The method of claim 1 , further comprising the step of:

applying a coating to an outer surface of the overall tubular structure.

4. The method of claim 1 , wherein forming the absorbent body includes:

cutting a fluid absorbent material to a specific length and width;

rolling the cut fluid absorbent material around a first set of elongated machine prongs; and

removing the first set of elongated machine prongs.

5. The method of claim 4 , wherein the fluid absorbent material is cotton.

6. The method of claim 1 , wherein enclosing the absorbent body within a protective sleeve further includes:

stitching together the first distal end and the second distal end of the porous sheet.

7. The method of claim 6 , wherein enclosing the absorbent body within a protective sleeve further includes:

pinching closed the second distal end of the absorbent body before stitching together the first distal end and the second distal end of the porous sheet.

8. The method of claim 1 , wherein enclosing the absorbent body within a protective sleeve further includes:

pinching together a second distal end of the porous sheet that extends beyond the second distal end of the absorbent body; and

pushing the pinched together second distal end of the porous sheet through the hollow interior and past the first distal end of the absorbent body, wherein pushing the second distal end of the porous sheet tucks the first distal end of the porous sheet between the porous sheet and the absorbent body.

9. The method of claim 1 , wherein coupling the string to the protective sleeve includes:

punching an end of the string through a top outer surface of the protective sleeve;

pushing the string through the protective sleeve, a top portion of the absorbent body, an inner surface of the protective sleeve, the hollow region, another inner surface of the protective sleeve, a bottom portion of the absorbent body, and out from a bottom outer surface of the protective sleeve; and

coupling the end of the string to a remaining portion of the string that has not passed through the protective sleeve.

10. The method of claim 9 , wherein coupling the end of the string includes passing the end of the string through a loop in the remaining portion of the string.

11. A method of manufacturing a tubular shaped tampon, the method comprising:

cutting a fluid absorbent material to a specific length and width;

rolling the cut fluid absorbent material around a first set of elongated machine prongs or an elongated rod, wherein the rolling forms an absorbent body defining a cylindrical shape having an exterior surface, a hollow interior, an interior surface, and first and second opposing distal ends;

rolling a porous sheet around the absorbent body, wherein the porous sheet extends beyond both distal ends of the absorbent body;

pinching together using a second set of elongated machine prongs a first distal end of the porous sheet that extends beyond the first distal end of the absorbent body;

pushing using the second set of elongated machine prongs the pinched together first distal end of the porous sheet through the hollow interior and past the second distal end of the absorbent body, wherein the first distal end of the porous sheet and a second distal end of the porous sheet both extend past the second distal end of the absorbent body;

removing the first set of elongated machine prongs or elongated rod while pushing using the second set of elongated machine prongs;

pinching closed the second distal end of the absorbent body;

stitching together the first distal end and the second distal end of the porous sheet such that the porous sheet then forms a protective sleeve enclosing the absorbent body, wherein the absorbent body and protective sleeve combine to define an overall tubular structure having an inner hollow region and a first diameter;

punching an end of a string through a top outer surface of the protective sleeve;

pushing the string through the protective sleeve, a top portion of the absorbent body, an inner surface of the protective sleeve, the hollow region, another inner surface of the protective sleeve, a bottom portion of the absorbent body, and out from a bottom outer surface of the protective sleeve; and

coupling the end of the string to a remaining portion of the string that has not passed through the protective sleeve.

12. The method of claim 11 , further comprising the steps of:

compressing the overall tubular structure to a second diameter that is less than the first diameter; and

applying a coating to an outer surface of the overall tubular structure.
