  • Publication number: 20250352406
    Abstract: 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.

  • Patent number: 12376998
    Abstract: The present disclosure relates to apparatuses and methods for making tampons including primary and secondary absorbent members. During assembly, primary absorbent members, a continuous length of secondary absorbent members, and a continuous cord are advanced in a machine direction. Leading edges of the primary absorbent members are separated from each other in the machine direction by a pitch distance. Discrete secondary absorbent members are cut from the continuous length of secondary absorbent members. Leading edges of the discrete secondary absorbent members are also separated from each other in the machine direction by the pitch distance. The continuous cord is positioned on the secondary absorbent members. And a secondary absorbent member is positioned in contact with a primary absorbent member. A thread is combined with the continuous cord, the secondary absorbent member, and the primary absorbent member.

  • Publication number: 20250152431
    Abstract: A tampon product including an applicator with a hollow barrel portion and an ejection plunger within the barrel portion, is disclosed. One or both of the barrel portion and the ejection plunger may have a cylindrical form and be formed of a paper, and have a coating applied to the paper, wherein the coating is not predominately constituted by a material derived from petroleum. The coated paper barrel portion and/or ejection plunger may be manufactured to as to exhibit a static Relative Sliding Resistance Coefficient (CSR) no greater than 0.250 and/or a kinetic CSR no greater than 0.210, for purposes of smooth manufacturing. In combination or alternatively, the coated paper barrel portion and/or ejection plunger may be manufactured to as to exhibit a static Gripping Slip Resistance Coefficient (CGSR) no less than 0.190 and/or a kinetic CGSR no less than 0.170, for purposes of consumer satisfaction.
