Description

    FIELD OF THE INVENTION
  • This invention relates to a tampon comprising a plurality of cords or strips joined at the first end, the second end, the center portion, or both the first end and second end.
  • BACKGROUND OF THE INVENTION
  • A wide variety of absorbent catamenial tampons have long been known in the art. It is well known that the primary function which tampons provide is leakage protection, that is, preventing menstrual discharges from leaking out of body onto an undergarment. The absorbency of tampons is generally regulated and categorized publicly so that consumers can select a tampon with appropriate absorbency in accordance with their expected level of menstrual flow. However, even when consumers have chosen the absorbency correctly, it has been found that even the best tampons do not prevent unexpected leakage. This unexpected leakage is commonly called “bypass” failure, which occurs when the menses travels in the space between the vagina and the tampon and the tampon fails to intercept the flowing menses due to lack of total coverage of the vagina by the tampon. Because bypass failure imposes unpredictability and persistent fear of leakage to consumers, it is considered unacceptable and an effective solution has been long desired by consumers.
  • It is an object of the present invention to provide a tampon that improves coverage and solves the problem of bypass failure. The body of the tampon of the present invention comprises a plurality of cords or strips joined at the first end, the second end, the center portion, or both the first end and second end. Not to be bound by theory, the inventors believe the nature of materials chosen to comprise the body of the tampon enable the strips or cords to exhibit improved deformation and spreading within the vagina over known tampons comprised of separate filaments and fibers, as described in for example U.S. Pat. No. 3,320,956 issued to Stelger on May 23, 1967 and U.S. Pat. No. 4,335,721 issued to Matthews on Jun. 22, 1982. Moreover, the nature of the materials that comprise the body of the tampon provide sufficient void volume for absorbency. It is believed that the tampon of the present invention provides significant improvement of the coverage and solves the problem of bypass failure.
  • SUMMARY OF THE INVENTION
  • This invention relates to a tampon having a body comprising a first end, a second end, and a center portion. The body includes a plurality of cords or strips joined at the first end, the second end, the center portion or both the first and second end. The plurality of strips and cords being selected from the group being selected from the group consisting of, films, woven materials, absorbent foams, superabsorbent polymers, and mixtures thereof.
  • BRIEF DESCRIPTION OF THE DRAWINGS

  • DETAILED DESCRIPTION OF THE INVENTION
  • As used herein “applicator” refers to a device or implement that facilitates the insertion of a tampon, medicament, treatment device, visualization aid, or other into an external orifice of a mammal, such as the vagina, rectum, ear canal, nasal canal, or throat. Non-limiting specific examples of such include any known hygienically designed applicator that is capable of receiving a tampon may be used for insertion of a tampon, including the so-called telescoping, tube and plunger, and the compact applicators, an applicator for providing medicament to an area for prophylaxis or treatment of disease, a spectroscope containing a microcamera in the tip connected via fiber optics, a speculum of any design, a tongue depressor, a tube for examining the ear canal, a narrow hollow pipe for guiding surgical instruments, and the like.
  • The term, “cords,” as used herein, refers to a long slender flexible material consisting of several strips of material woven or twisted together.
  • The term “digital tampon,” as used herein, refers to a tampon which is intended to be inserted into the vaginal canal with the user's finger and without the aid of an applicator. Thus, digital tampons are typically visible to the consumer prior to use rather than being housed in an applicator.
  • The term “joined” or “joined,” as used herein, encompasses configurations in which a first element is directly secured to a second element by affixing the first element directly to the second element; configurations in which the first element is indirectly secured to the second element by affixing the first element to intermediate member(s) which in turn are affixed to the second element; and configurations in which the first element is integral with the second element; i.e., the first element is essentially part of the second element.
  • As used herein, the term “longitudinal axis” of a tampon refers to the axis that runs through the center of the tampon as shown in FIG. 1. A portion of the tampon may be asymmetric about the longitudinal axis, such as when the withdrawal end region is flared and distorted from the original shape of the rest of the tampon (such as a “fin shape”). Further, the longitudinal axis may be linear or non-linear.
  • As used herein, the term “radial axis” of a tampon refers to the axis that runs at right angles to the longitudinal axis of the tampon as shown in FIG. 1.
  • The term “rolled,” as used herein, is the configuration of the body of the tampon after winding the absorbent material upon itself.
  • As used herein, the term “tampon,” refers to any type of absorbent structure that is inserted into the vaginal canal or other body cavities for the absorption of fluid therefrom, to aid in wound healing, or for the delivery of active materials, such as medicaments, or moisture.
  • The term “vaginal cavity,” “within the vagina,” and “vaginal interior,” as used herein, are intended to be synonymous and refer to the internal genitalia of the mammalian female in the pudendal region of the body. The term “vaginal cavity” as used herein is intended to refer to the space located between the introitus of the vagina (sometimes referred to as the sphincter of the vagina or hymeneal ring,) and the cervix. The terms “vaginal cavity,” “within the vagina” and “vaginal interior,” do not include the interlabial space, the floor of vestibule or the externally visible genitalia.
