Abstract
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.
