There is provided a tampon pledget that includes one or more enhanced features that result in the pledget exhibiting increased bypass leakage prevention. These enhanced features may include, but are not limited to, geometry, absorption, and any combinations thereof. There is also provided one or more methods for constructing a tampon pledget having increased bypass leakage protection.

Tampon pledget for increased bypass leakage protection

The present invention provides a tampon pledget with one or more of the following properties: increased absorbency rate; high absorbent capacity and fluid retention; rapid expansion potential; and ease of ejection of the pledget from the applicator. Surprisingly, the one or more properties are achieved by using a modified dual cross-pad, folded, compressed tampon pledget design.

A tampon pledget is made by assembling one or more pads in a pad compression configuration, radially compressing the pad compression configuration in a traverse direction into a cylindrical form, and axially compressing the cylindrical form in a direction along a vertical axis to form the tampon pledget. In one embodiment, the axial compression is performed as a pressure is applied to at least one of a first and a second end of the cylindrical form. In one aspect of the present invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 6.0 grams to 9.0 grams and a density of about 0.4603 grams/cubic centimeter. In another aspect of the invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 9.0 grams to 12.0 grams and a density of about 0.4755 grams/cubic centimeter.

Tampon pledget with improved by-pass leakage protection

The present invention provides a tampon applicator assembly having an applicator barrel with an insertion tip with a maximum of three petals. Additionally, the tampon applicator assembly can be provided with a tapered insertion tip. A shaped pledget can be housed in the applicator barrel, which provides support to the petals.

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&#xb0; and about 156&#xb0; and a curve represented by an equation range of y=16.127x&#x2212;1.5061x+0.0568x+0.0001 to y=6.9136x&#x2212;0.5598x+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.

Tampon insertion device for improved control and pledget placement

An apparatus for testing of medical products such as a feminine hygiene product, is presented. The apparatus includes a body, a pump and a vaginal canal assembly. The body includes an internal chamber and a bottom surface having a bore open to the internal chamber. The pump provides a fluid to the body. In one embodiment, the fluid is a menses simulant. The vaginal canal assembly includes an interior canal accepting the product. The vaginal canal assembly includes a passage providing the fluid to the interior canal. The apparatus includes a pressure regulator controlling pressure exerted on the vaginal canal assembly from a volume of air within the internal chamber. The apparatus includes a stand. The stand includes a retaining device and a locking device. The locking device cooperates with the retaining device to selectively secure the body in at least one of a rotational position and an angular position.
