Abstract
A method of assembling a tampon applicator includes providing a barrel with internal ridges that define a guide channel having an effective diameter. The method includes providing a plunger that has a finger flare with a circular shape and a flare diameter that is at least 15% larger than the effective diameter of the guide channel. The method includes assembling the plunger and the barrel by pushing the finger flare into the guide channel and deforming the finger flare into a non-circular shape while moving the finger flare through the guide channel. The method includes moving the finger flare out of the plunger end of the barrel and reestablishing the circular shape of the finger flare.
