Abstract
A tampon applicator assembly has a barrel with a fingergrip. The fingergrip has one or more flared portions and/or one or more rib-like or ring-like gripping structures. A tampon applicator fingergrip includes one or more flared portions having a flare angle between about 139° and about 156° and a curve represented by an equation range of y=16.127x3−1.5061x2+0.0568x+0.0001 to y=6.9136x3−0.5598x2+0.0168x+0.0003, where y is an incremental increase in a height of the curve at a distance along a length of the curve.
Claims12
A tampon applicator fingergrip comprising:
- a fingergrip portion having a fingergrip surface that is the outermost surface of said fingergrip portion, said fingergrip surface having a virtually uniform radii surface as measured from a centerline of said fingergrip;
- and
- a flared portion directly connected to said fingergrip portion, said flared portion having a flare surface that is the outermost surface of said flared portion, said flare surface increasing in diameter from said fingergrip surface toward an end of said fingergrip that receives a plunger, said flare surface also having a curve represented by an equation range of y=16.127x3−1.5061x2+0.0568x+0.0001 to y=6.9136x3−0.5598x2+0.0168x+0.0003, where y is an incremental increase in a height of said curve at a distance along a length of said curve, said x being from 0 to 0.211 inches, and said flared portion having a flare diameter from 0.525 inches to 0.575 inches as said x is measured from 0 to 0.211.
A tampon applicator fingergrip comprising:
- a fingergrip portion having a fingergrip surface that is the outermost surface of said fingergrip portion, said fingergrip surface having a virtually uniform radii surface as measured from a centerline of said fingergrip;
- and
- a flared portion directly connected to said fingergrip portion, said flared portion having a flare surface that is the outermost surface of said flared portion, said flare surface increasing in diameter from said fingergrip surface toward an end of said fingergrip that receives a plunger, said flare surface also having a curve represented by an equation range y=4.8311x3−0.1841x2+0.086x−0.0006 to y=3.3937x3+0.0994x2+0.014x+0.00004, where y is an incremental increase in a height of said curve at a distance along a length of said curve, said x being from 0 to 0.250 inches, and said flared portion having a flare diameter from 0.450 inches to 0.500 inches as said x is measured from 0 to 0.250 inches.
