Tampon assembly having shaped pledget
A tampon assembly having a barrel, a plunger, and a pledget is provided. The plunger is slidably received in the barrel. The pledget is in the barrel between the insertion tip and the plunger so that a force applied on the plunger can expel the pledget from the barrel. The barrel has a plurality of petals defining an insertion tip, which has a first taper ratio of more than about 0.3 to less than 1.0. The pledget has a shaped tip that is disposed in the insertion tip.
1. A tampon assembly comprising:
a barrel having a tubular wall forming a first end and a second end, said barrel having a plurality of discrete petals at said first end that form an insertion tip, said petals being separated from each other by a plurality of cuts that form a break of material through said tubular wall of said barrel, said petals having an inner surface, said insertion tip being of an axial extant defined from a distal end of said first end to a first plane defined at a base of said plurality of petals, said insertion tip having a first taper ratio of more than about 0.3 to less than 1.0 throughout said axial extant;
a plunger being slidably received in said barrel; and
a pledget being disposed in said barrel between said insertion tip and said plunger so that a force applied on said plunger can expel said pledget from said barrel, wherein said pledget has a tapered tip compatible with and proximate said insertion tip, said tapered tip of said pledget having an outer radial dimension that decreases between a distal, tip end of said pledget and a second plane through said pledget where said taper begins, wherein said tapered tip contacts and supports about 100% of said inner surface of said plurality of petals, prior to insertion of the tampon assembly into a body of a user, to prevent forces on said insertion tip applied during insertion from collapsing said plurality of petals inward towards said pledget, whereby the compatibility of said insertion tip of said barrel and said tapered tip of said pledget mitigates against said plurality of petals closing during insertion which closing can pinch a user.
2. The assembly as in claim 1 , wherein said tapered tip has a density that is higher than the density of the remainder of said pledget.
3. The assembly as in claim 1 , wherein said tapered tip has a density that is substantially equal to the density of the remainder of said pledget.
4. The assembly as in claim 1 , wherein said tapered tip has a second taper ratio approximately equal to said first taper ratio.
5. The assembly as in claim 1 , wherein said tapered tip has a second taper ratio that is greater than said first taper ratio.
6. The assembly as in claim 1 , wherein said tapered tip has a second taper ratio that is less than said first taper ratio.
7. The assembly as in claim 1 , wherein said tapered tip occupies about 50% of the volume of said insertion tip.
8. The assembly as in claim 1 , wherein said tapered tip occupies about 75% of the volume of said insertion tip.
9. The assembly as in claim 1 , wherein said tapered tip occupies about 90% of the volume of said insertion tip.
10. The assembly as in claim 1 , wherein said pledget comprises a material selected from the group consisting of rayon fibers, cotton fibers, pulp fibers, and any combinations thereof.
11. The assembly as in claim 1 , wherein the taper ratio is linear along the entire extant of the length.
12. A tampon assembly comprising:
a barrel having a tubular wall with a first end and a second end opposite said first end, said barrel having a plurality of discrete petals at said first end that define an insertion tip, said petals being separated from each other by a plurality of cuts that form a break of material through said tubular wall of said barrel, said insertion tip starting at a distal end of said first end and terminating at a first plane defined at a base of said plurality of petals, said insertion tip having a first taper ratio throughout its axial extant, said insertion tip having an inner surface area;
a plunger being slidably received in said barrel; and
a pledget having a front end and a rear end opposite said front end, said pledget having a tapered tip at said front end, said tapered tip having a taper so that an outer radial dimension of said tapered tip decreases between said front end of said pledget and a second plane through said pledget where said taper begins, said tapered tip having a second taper ratio that is equal to said first taper ratio, said pledget being disposed in said barrel so that said tapered tip contacts to support about 100% of said inner surface area of said insertion tip prior to insertion of the tampon assembly.
13. The assembly as in claim 12 , wherein said insertion tip has a first taper ratio of more than about 0.3 to less than 1.0.
14. The assembly as in claim 12 , wherein said pledget comprises a material selected from the group consisting of rayon fibers, cotton fibers, pulp fibers, and any combinations thereof.
15. The assembly as in claim 12 , wherein said tapered tip has a density that is higher than or substantially equal to the density of the rest of said pledget.
