Tampons and methods for making tampons
Aspects of the present disclosure relate to methods for making tampons including primary absorbent members and secondary absorbent members. In some configurations, the tampons may be constructed with a primary absorbent member formed by a primary absorbent pad in a rolled configuration. In some configurations, the tampons may be constructed with a primary absorbent member formed by first and second primary absorbent pads positioned in a crossing configuration.
Tampon with wicking member adapted for improved manufacturability and wicking performance
The disclosed tampon may include a pledget having a rearward end; a wicking member having a trailing portion trailing the rearward end and having a rearward edge; and a withdrawal cord with an attached portion attached to the pledget and a free portion trailing the rearward edge. In an opened condition the pledget has a pair of side edges and a pledget width, and includes fibrous absorbent material and an outer cover of a first section of nonwoven web at least partially covering the absorbent material, the trailing portion of the wicking member including at least four layers of nonwoven web, at least one of which is an extension of the first section of nonwoven web. The wicking member may have a width substantially equal to the pledget width; and the trailing portion may have a length of at least about 10 mm and no greater than about 60 mm.
TAMPON PLEDGET WITH IMPROVED BY-PASS LEAKAGE PROTECTION
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 ASSEMBLY HAVING A SHAPED PLEDGET
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.

Tampon and method for making same
Tampons that provide a balance of adequate absorption with sufficient expansion properties during absorption and a relatively small initial diameter for comfortable insertion are provided.
Tampon with wicking member adapted for improved manufacturability and wicking performance
A tampon including a pledget, a wicking member and a withdrawal cord is disclosed. The pledget includes a mass of fibrous absorbent material disposed within or between one or more layers of an outer cover formed of a first nonwoven web material. The wicking member includes a second nonwoven web material distinct from the first nonwoven web material and the withdrawal cord. The wicking member is joined in direct contact with a surface of the pledget, and has a width less than the width of the pledget width.

A tampon including a pledget, a wicking member and a withdrawal cord is disclosed. The pledget includes a mass of fibrous absorbent material disposed within or between one or more layers of an outer cover formed of a first nonwoven web material. The wicking member includes a second nonwoven web material distinct from the first nonwoven web material and the withdrawal cord. The wicking member is joined in direct contact with a surface of the pledget, and has a width less than the width of the pledget width.
TAMPON INCLUDING SECONDARY ABSORBENT
A tampon having an insertion end and a withdrawal end. The tampon includes a primary absorbent, disposed toward the insertion end, a secondary absorbent, and a withdrawal member. The secondary absorbent may have a mean length from the primary absorbent and at least three segments each having a mean segment mass. The mean segment mass may be selected such that the secondary absorbent tapers as the secondary absorbent material extends from the primary absorbent. The primary absorbent including at least one of rayon fibers and cotton fibers and having improved fluid handling due to dynamic expansion of the tampon at a relatively reduced dry tampon mass.
