Claims
- 1. A tampon assembly comprising:
- a tampon pledget having an insertion end, a rear portion and an intermediate section extending for a length between said insertion end and said rear portion,
- a tampon applicator barrel having a rim structure located peripherally about a first end thereof for supporting said tampon pledget at said intermediate section, wherein said rear portion of said tampon pledget is positioned in said tampon applicator barrel and said insertion end of said tampon pledget is positioned outside of said tampon applicator barrel,
- said rim structure having a frustum-shape that is tapered angularly inward toward said intermediate section of said tampon pledget at a predetermined angle away from a rear portion of said tampon applicator barrel, wherein said frustum-shape tapers angularly inward to a reduced width opening and said opening is smaller than a largest diameter of said insertion end, and
- wherein said rim structure permits said insertion end of said tampon pledget to pass through said first end of said tampon applicator barrel and ejection of said tampon pledget from said tampon applicator barrel and yet prevents said insertion end of said tampon pledget from entering into said tampon applicator barrel when an axial force is applied to said insertion end during formation of said insertion end.
- 2. The tampon assembly of claim 1, wherein said rim structure comprises a plurality of segments located peripherally about said first end of said tampon applicator barrel, each of said plurality of segments being directed angularly inward toward said intermediate section of said tampon pledget.
- 3. The tampon assembly of claim 2, wherein each of said plurality of segments has a distal edge for contacting said intermediate section of said tampon pledget and a substantially opposite and parallel hinge having a length that is longer than a length of said distal edge.
- 4. The tampon assembly of claim 2, wherein each of said plurality of segments has a distal radius for contacting said intermediate section of said tampon pledget and said plurality of segments come together to form a scalloped edge at said opening.
- 5. The tampon assembly of claim 1, wherein said predetermined angle of said frustum-shape, from said rear portion of said tampon applicator barrel to said intermediate section of said tampon pledget, is about 30 degrees to about 45 degrees.
- 6. The tampon assembly of claim 5, wherein said predetermined angle is about 45 degrees.
- 7. The tampon assembly of claim 1, wherein said rim structure is capable of maintaining said intermediate section of said tampon pledget in said tampon applicator barrel against the axial force when the axial force is about 15% less than the columnar strength of said tampon applicator barrel.
- 8. The tampon assembly of claim 1, wherein said insertion end of said tampon pledget is radially expanded relative to said rear portion of said tampon pledget.
- 9. A tampon assembly including a tampon pledget having an insertion end, a rear portion and an intermediate section located at an outer peripheral position of the tampon pledget between the insertion end and the rear portion, said tampon assembly comprising:
- a tampon applicator barrel having a rim structure at a first end for supporting the tampon pledget at the intermediate section, and having a remainder portion connected to the intermediate section, wherein the rear portion of the tampon pledget is positioned in said tampon applicator barrel and the insertion end of the tampon pledget is positioned outside of said tampon applicator barrel;
- said rim structure having a frustum-shape that is tapered angularly inward toward the intermediate section at a predetermined angle away from the remainder portion of said tampon applicator barrel, whereby said rim structure permits the rear portion of the tampon pledget to eject from said tampon applicator barrel and yet substantially hinders the insertion end of the tampon pledget from entering said tampon applicator barrel when an axial force is applied to the insertion end during formation of the insertion end;
- said rim structure comprises a plurality of segments located peripherally about said first end of said tampon applicator barrel, each of said plurality of segments being directed angularly inward toward the intermediate section of the tampon pledget, each of said plurality of segments having at least two tapered, lateral sides that abut the lateral sides of each pair of adjacent segments to form said frustum-shaped rim structure.
