20080287902 | TAMPON PLEDGET FOR INCREASED BY-PASS LEAKAGE PROTECTION - The present invention provides a tampon pledget with one or more of the following properties: increased absorbency rate; high absorbent capacity and fluid retention; rapid expansion potential; and ease of ejection of the pledget from the applicator. Surprisingly, the one or more properties are achieved by using a modified dual cross-pad, folded, compressed tampon pledget design. | 11-20-2008 |
20080319273 | In-vitro measurement of catamenial tampon systems - An apparatus for testing of medical products such as a feminine hygiene product, is presented. The apparatus includes a body, a pump and a vaginal canal assembly. The body includes an internal chamber and a bottom surface having a bore open to the internal chamber. The pump provides a fluid to the body. In one embodiment, the fluid is a menses simulant. The vaginal canal assembly includes an interior canal accepting the product. The vaginal canal assembly includes a passage providing the fluid to the interior canal. The apparatus includes a pressure regulator controlling pressure exerted on the vaginal canal assembly from a volume of air within the internal chamber. The apparatus includes a stand. The stand includes a retaining device and a locking device. The locking device cooperates with the retaining device to selectively secure the body in at least one of a rotational position and an angular position. | 12-25-2008 |
20090036859 | Anthroprometrically expandable tampon pledget - A tampon pledget has an absorbent mass of material and a withdrawal string located at one end thereof. During use, the tampon pledget expands to take on a geometric configuration that approximates the shape of the vagina into which the tampon pledget is inserted. An anthroprometrically expandable tampon pledget has an absorbent mass of material that is defined by a first end having a first density, a second end having a second density, and a portion intermediate the first and second ends. The material expands at different rates upon being contacted by body fluids, thereby allowing the tampon pledget to conform to the shape of a vagina. A method of making an expandable tampon pledget includes the steps of providing an absorbent material, attaching a string thereto, and compressing the material into a cylindrical shape such that a density gradient is realized over a length of the compressed material. | 02-05-2009 |
20090281474 | TAMPON PLEDGET HAVING IMPROVED EXPANSION AND PROCESS FOR PRODUCING SAME - A feminine hygiene product is presented. The feminine hygiene product includes a body having a mass of compressed fibrous material, an insertion end and a withdrawal end. The body has an overall length L. The insertion end has a diameter A and the withdrawal end has a diameter B. In an initial state, diameter B is at least about equal to up to about ten percent greater than the diameter A. When exposed to a fluid, diameter B radially expands such that a ratio of diameter B to the diameter A is about 1.25 to 1. In one embodiment, the feminine hygiene product is a vaginal tampon and when exposed to a fluid, diameter B expands more rapidly than diameter A to substantially seal a bottom portion of a vaginal cavity and prevent bypass leakage. | 11-12-2009 |
20110077612 | TAMPON PLEDGET FOR INCREASED BYPASS LEAKAGE PROTECTION - There is provided a tampon pledget that includes one or more enhanced features that result in the pledget exhibiting increased bypass leakage prevention. These enhanced features may include, but are not limited to, geometry, absorption, and any combinations thereof. There is also provided one or more methods for constructing a tampon pledget having increased bypass leakage protection. | 03-31-2011 |
20110224637 | LOW pH, OPTIMAL ORP, AND ODOR-REDUCING FIBERS, A PROCESS FOR MAKING THE FIBERS, AND ARTICLES MADE THEREFROM - The present disclosure provides low pH fibers that are treated with additives, preferably after regenerating the cellulosic fiber, to control the pH and oxidation-reduction potential (ORP) in an aqueous environment where the fiber is placed. The low pH fibers can be formed into fibrous articles such as tampons or wipes. The low pH fibers with the additives provide health benefits to the user in that they hinder the ability of harmful bacteria to flourish. | 09-15-2011 |
20120175803 | IN-VITRO MEASUREMENT OF CATAMENIAL TAMPON SYSTEMS - An apparatus for testing of medical products such as a feminine hygiene product, is presented.

The stand includes a retaining device and a locking device. The locking device cooperates with the retaining device to selectively secure the body in at least one of a rotational position and an angular position. | 07-12-2012 |
