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 |
20100164139 | Barrel for a tampon application assembly and methods of forming - A method of forming a barrel for a tampon applicator assembly including molding a barrel then forming a rearward taper region in an area of the barrel is provided. The method includes molding a first portion of the barrel in a first mold part and a second portion of the barrel in a second mold part, the first and second mold parts meeting at a maximum outer dimension of the first portion, ejecting the barrel from the first and second mold parts, and forming a flared region in an area of the second portion. | 07-01-2010 |
20100198133 | MICROCELLULAR INJECTION MOLDING PROCESSES FOR PERSONAL AND CONSUMER CARE PRODUCTS AND PACKAGING - 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. | 08-05-2010 |
20110009803 | TAMPON ASSEMBLY PROVIDING PROPER BODILY PLACEMENT OF A PLEDGET - Provided is a tampon applicator having one or more insertion indicators to gauge and/or control the insertion depth of a tampon. The one or more insertion indicators may be located on the tampon applicator barrel, plunger, tampon, removal string, or any combinations thereof. As a result of the one or more insertion indicators, a woman can adjust the insertion depth of the tampon to her body's requirements ensuring leakage protection, comfort, or both. | 01-13-2011 |
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 |
20120061870 | METHODS FOR MICROCELLULAR INJECTION MOLDING - In a method of microcellular injection molding, a polymer and a supercritical fluid are processed. A condition of processing the polymer and/or the supercritical fluid is adjusted to control a weight of a plastic part and/or a surface characteristic of a plastic part produced. In another method of producing a plastic part using microcellular injection molding, a polymer is heated and melted and a supercritical fluid is added thereto. The resulting mix is a single-phase polymer-gas solution comprising the polymer and the supercritical fluid. The polymer and/or the supercritical fluid are adjusted to control the weight of the plastic part and/or a surface characteristic of the plastic part. Once adjusted, the melted polymer with the supercritical fluid is injected into a mold. Upon injecting the melted polymer and supercritical fluid, a pressure drop causes the supercritical fluid to nucleate in the melted polymer, thereby causing nucleation of bubbles. | 03-15-2012 |
