    Abstract: A tampon showing improved leakage protection through improved expansion characteristics is disclosed. The tampons disclosed demonstrate these improved expansion characteristics particularly in the width dimension without introducing new drawbacks. Preferred tampons are described which are compressed to an initial size comparable to current tampons, but which expand to a width exceeding that achieved by current tampons. Such increased expansion is preferably accomplished without an increase in the total absorbency of the tampon. Tampons of various absorbencies are disclosed having increased total expansion in the width direction compared to current tampons. Additionally, tampons of various absorbencies which expand to a greater degree in the width direction under pressure are also disclosed. Tampons of various absorbencies which expand at a rate exceeding that achieved previously are also disclosed.

  • Patent number: 6811549
    Abstract: A drug or diagnostic agent) is delivered intravaginally or to the interlabial space by positioning an interlabial device, such as an absorbent pad, between the labia. The pad is retained between the labia to deliver an active agent, or allow a reaction with a diagnostic agent. Alternatively, the pad is applied after medication is administered, to help reduce discomfort to the subject, or loss of medication. The active agent may be carried by the pad itself, or in an intravaginal extension of the pad, or separately in a suppository or other dosage form. In particular examples, the pad has a smaller minor portion superimposed on a larger major portion, and the smaller minor portion is inserted as a leading edge between the labia of the subject to facilitate interlabial insertion. In another example, the pad is placed interlabially after insertion of an agent into the vagina.

  • Patent number: 6773423
    Abstract: A catamenial tampon in the form of a soft, conformable, hollow bag which is capable of being inserted digitally or through the use of a unique applicator. The tampon has an outer surface, an inner surface, a head portion and a trailing portion. The inner surface of the tampon defines an interior of the tampon wherein the head portion is closed and the trailing portion defines an opening into the interior of the tampon. The tampon may have a shape modulus of compression of less than 0.05 pounds force. The tampon preferably includes a removal string, which can be attached to the inside or outside surface of the tampon.

  • Publication number: 20040153042
    Abstract: The present invention provides an interlabial pad, which includes an absorber (13) and comprises an absorbing sheet portion (14a), which faces against the body side in wearing the pad and a support sheet portion (14b), which backs the absorber (14a). The absorber (14a) comprises of a pair of absorbing sheet bodies (16) which are divided along the substantial center line of the interlabial pad 14, the absorbing sheet (16) and the impermeable support sheet (12) are bonded with each other on the peripheral edge portion (15) of the interlabial pad (14) to form a void portion (18) between the absorbing sheet body (16) and the support sheet (12) through which the menstrual blood can flow into. Thereby the menstrual blood flowing down along the inner wall of the labia can be rapidly transferred into the absorber and the shape fitness (fitting ability) of the pad in labia can be improved.

  • Patent number: 6758839
    Abstract: A tampon for feminine hygiene or medical purposes comprising a nonwoven cover having at least one, outwardly directed, smooth surface and substantially enclosing a liquid absorbing core wherein the nonwoven cover comprises at least partly thermoplastic, heat-sealable fibers and pressed to the final shape of the tampon. Before the tampon blank is covered with the nonwoven covering web, said web was subject to the use of heat and pressure during the manufacturing of the tampon as to smooth out at least the outer surface of the nonwoven covering web, whilst maintaining the structure of the nonwoven covering web and the absorbency of the tampon. Thereby, it is achieved that the tampon can also be more easily and more comfortably introduced into and withdrawn from a body cavity before and after the days of stronger menstruation or at the occurance of only less vaginal exudation as garment protection.

  • Patent number: 6746418
    Abstract: There is provided a tampon pledget or tampon applicator that is covered by a wrapper having microcapsules thereon. Alternatively, the microcapsules may simply be disposed on the tampon pledget or tampon applicator. The microcapsules may contain a lubricant or a fragrance or a combination of both. The microcapsules may be ruptured prior to inserting the tampon pledget or tampon applicator and the resultant free-flowing lubricant and/or fragrance is spread on the tampon pledget, tampon applicator, or a combination thereof. The lubricant increases the ease and comfort of inserting and positioning the tampon pledget or tampon applicator. The amount of lubricant desired may be controlled by varying the pressure applied to the microcapsules. Thus, the number of microcapsules ruptured can be controlled by varying the pressure applied.

  • Patent number: 6743212
    Abstract: The present invention relates to a tampon having an absorbent structure and a multilayered cover substantially enclosing the absorbent structure. The cover has an outer layer capable of retaining liquid and an inner layer disposed between the outer layer and the absorbent structure. The inner layer creates a controlled interruption of fluid flow between the outer layer and the absorbent structure. This interruption allows the outer layer retains sufficient liquid to minimize vaginal wall drying prior to saturation of the absorbent structure.

  • Publication number: 20040073184
    Abstract: The invention is directed to an absorbent interlabial device. The absorbent interlabial device has a body contacting surface, a garment facing surface opposing the body contacting surface, an interior region, and a periphery region which surrounds the interior region. The body contacting surface is liquid permeable. The absorbent interlabial device comprises an absorbent member disposed between the garment facing surface and the body contacting surface. The absorbent member has a body facing surface and a garment facing surface opposing the body facing surface. The absorbent interlabial device has a convex portion on the body contacting surface in the interior region, and a concave portion on the garment facing surface in the interior region. The convex portion and the concave portion are formed in a face-to-face relationship. The invention is also directed to a method for making such an absorbent interlabial device.
