Definitions

  • the present invention relates to a novel tampon applicator having an expulsion force controller providing expulsion of a tampon.
  • the internal vaginal cavity in its normal state has a shape of a flattened bag with its minimum width near the introitus and its maximum width near the cervix. It is desirable, therefore, when considering a tampon for catamenial use, to provide a structure which, in its initial state, is of a size small enough to pass through the vaginal orifice without discomfort, and once delivered and placed inside the vaginal cavity beyond the restrictions of the orifice, can increase its dimension, particularly in the lateral direction, to cover substantially large portions of the vaginal surface from one side to the other to prevent early bypass of the menstrual discharges from the cervix. This side-to-side coverage is a preferred object of this invention.
  • the vaginal wall in its normal state is flaccid and has multiple folds and wrinkles which provide channels through which a significant portion of the menstrual fluids normally flow, it is also important that the absorbent tampon be as soft and conformable as possible to conform to the shape of the vaginal cavity and fit within these channels to minimize leakage.
  • absorbent catamenial tampons are small, highly compressed, cylindrical rigid plugs about 5 to about 20 mm in diameter and from about 35 to about 60 mm in length. Because of the need for absorbent capacity, they are usually formed from batts much larger in size than the vaginal orifice and compressed to the small size indicated above to facilitate insertion. As fluid is absorbed, these compressed tampons are designed to re-expand. While it has been found that these compressed tampons perform their intended function tolerably well, even the best of them do not re-expand sufficiently, or fast enough, to provide good transverse coverage against leakage even though the vertical blockage may be satisfactory.
  • a tampon in particular, a deformable tampon, inserted using the tampon applicator constructed according to the invention discussed herein yields the side-to-side coverage of the vaginal cavity immediately or soon after the time of insertion, even with no help of fluid absorption, and thereby can provide even further improvements in leakage protection, comfort, and low wearing awareness, as compared to currently marketed tampon applicators and previous attempts to improve tampon applicators.
  • the tampon applicator has a tampon holder tube.
  • the tampon holder tube has a hollow interior portion, an interior surface, an exterior surface, a longitudinal axis, an outer perimeter.
  • the tampon holder has a first end dimensioned for insertion into a vaginal cavity, a second end positioned oppositely to the first end, a force controller, and at least one side expulsion member positioned at the first end of the tampon holder tube.
  • the side expulsion member has a weakened region located at its base.
  • the tampon has a body having a first end, a center, and a second end.
  • the body has a joined portion.
  • the body has a plurality of absorbent strips joined at the joined portion.
  • the strips are selected from the group consisting of nonwoven materials, films, woven materials, absorbent foams, superabsorbent polymers, and mixtures thereof.
  • the tampon is housed within the hollow interior portion of the tampon holder tube in a pre-expelled position.
  • FIG. Ia is a perspective view of a tampon applicator and tampon in its pre- expelled state.
  • FIG. Ib is a top view of the tampon applicator of FIG. Ia.

  • 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.

  • directionally expel By the terms “directionally expel,” “directed expulsion,” or “directional expulsion,” it is meant herein and as seen in FIG. Ia, that embodiments of the tampon applicators 21 of the present invention will expel a tampon 20 along the longitudinal axis 45 and cause it to be placed in a position within the vaginal cavity to expand outwardly towards the walls of a female user's vaginal cavity.
  • Such directional expulsion causes the tampon applicator 21, when inserted into the vaginal cavity of a female user, to allow the tampon 20 to expand in the transverse direction thus providing improved coverage of a female user's vaginal cavity.
  • expelled is meant the position after the tampon 20 is forced out of the tampon applicator 21.
  • side-to-side coverage it is meant herein and as seen in FIG. 3b that the tampon 20 once directionally expelled, will have at least two sections thereof positioned outwardly toward the sides or walls of a female user's vaginal cavity.

  • the side expulsion members 31 aid in the trajectory of the tampon 20 because the side expulsion members' 31 axial force 40 to expel the tampon 20 is less than the axial force 40 to expel the tampon 20 from the force controllers 30. Because the side expulsion members' 35 axial force 40 is less, this aids in tampon's 20 proper placement which provides side-to-side coverage in the vaginal cavity.

Abstract

L'invention concerne un tampon et un applicateur de tampon également utilisé pour l'expulsion du tampon. L'applicateur de tampon comprend un tube de support de tampon. Le tube de support de tampon comprend une partie intérieure creuse, une première extrémité conçue pour être insérée dans la cavité vaginale, une seconde extrémité située à l'opposé de la première extrémité, un régulateur de force et au moins un élément d'expulsion latéral. L'élément d'expulsion latéral comporte une zone fragilisée au niveau de sa base. Le tampon comprend un corps possédant une première extrémité, un centre et une seconde extrémité. Ce corps comporte une partie de jointure et une pluralité de bandes absorbantes jointes au niveau de la partie de jointure. Les bandes sont constituées d'une matière choisie parmi des matières non tissées, des films, des matières tissées, des mousses absorbantes, des polymères superabsorbants et des mélanges correspondants. Le tampon est logé dans la partie intérieure creuse du tube de support de tampon dans une position précédant l'expulsion.
