a wall forming a tube with a center axis therthrough and with a hollow interior volume, the tube having a first barrel end and a second barrel end opposite the first barrel end that is a free end, the first barrel end and the second barrel end form a length therebetween that corresponds to the length of the center axis, the tube increasing in diameter along the length of the tube from a first diameter to a second diameter that forms a main body section, and decreasing in diameter along the length of the tube from the second diameter to a third diameter that forms a reverse taper section, wherein the center axis is substantially straight throughout the extant of the tube.

2. The tampon applicator barrel of claim 1 , wherein the third diameter connects directly to a finger grip section.

3. The tampon applicator barrel of claim 2 , wherein the finger grip section has a length from the third diameter to a fourth diameter, and wherein the tube decreases in diameter from the third diameter to the fourth diameter.

4. The tampon applicator barrel of claim 3 , wherein the tube increases in diameter along the length of the tube from the fourth diameter to a fifth diameter.

5. The tampon applicator barrel of claim 4 , wherein the fifth diameter is at the second barrel end.

6. The tampon applicator barrel of claim 5 , wherein the second barrel end has an opening into the interior volume for receipt of a plunger that forms an applicator assembly.

7. The applicator assembly of claim 6 , wherein the plunger has a first plunger end and a second plunger end, and wherein the first plunger end is within the interior volume and the second plunger end has a shape that is complimentary to the shape of the finger grip section between the fourth diameter and the fifth diameter.
