  • Publication number: 20100268182
    Abstract: 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.

  • Patent number: 7806882
    Abstract: A tampon that has a sensor and a signal line that peripherally connects the sensor with a peripheral signal processor. The sensor provides a blood wetting signal in response to a progressing blood saturation boundary in the tampon. The signal may be resistive, capacitive or optic. The simple sensor has two proximal signal terminals separated by a fluid responsive medium in wetting communication with the tampon's body. The tampon may be removed by use of the signal line. From signal timing and/or signal gradient the processor may predict when the tampon needs to be changed.

  • Publication number: 20100198133
    Abstract: A method of injection molding produces a microcellular material. In this method, a polymer is melted and blended with a supercritical fluid to produce a single-phase polymer-gas solution. This solution is injected through a nozzle and into a mold. When injected through the nozzle, gas in the solution (from the supercritical fluid) emerges from the polymer, which then solidifies. In emerging from the solution, the gas causes the nucleation of cells that result in a microcellular structure. A foam material comprises a polymer having a microcellular structure formed by the nucleation of micro-cells. The micro-cells are formed by the dispersing of a supercritical fluid in a liquid solution of the polymer when the polymer is subjected to a pressure drop. A feminine hygiene device is fabricated from a foamed polymer.

  • Publication number: 20090131852
    Abstract: This invention relates to a sanitary product for use by women for the absorption of menstrual fluid and such like. The product comprises a plug and a pad joined by a sheath. The plug is substantially cylindrical so that is fits comfortably in a vaginal cavity. The pad remains outside the vaginal cavity, but has an absorbent layer on an inward side proximal to the plug and a liquid impermeable layer on an outward side. In use, a wearer can insert a finger into the sheath from the outward side of the pad assist with insertion of the plug into the vaginal cavity. A string is provided that extends inside the sheath from the outward end of the plug to aid removal of the product. A line of weakness extends along the major axis of the pad, about which the pad is disposed to fold in use. This encourages the pad to fold around the plug to accommodate the plug during removal of the product, thus improving hygiene.
