20080244809Latex Gloves and Articles with Geometrically Defined Surface Texture Providing Enhanced Grip Method for In-Line Processing Thereof - Latex articles with geometrically defined surface structure providing enhanced grip characteristics in dry, wet or oily environments; and a method of making same comprising applying a polymeric coagulant coating to a smooth former surface, wherein the coating becomes tacky during drying, applying discrete coagulant particles of selected size, shape and distribution to the tacky coating to attach and protrude from the former surface with the polymeric coagulant coating, dipping the former into an aqueous latex emulsion, wherein the polymeric coagulant coating and the discrete coagulating particles destabilize the latex, thereby developing a latex layer, vulcanizing and stripping the latex article inside out, and dissolving the discrete coagulant particles in water or suitable solvents to reveal the geometrically designed texture with pre-selected size, shape and distribution of impressions providing improved dry, wet and oily surface grip by removal of a fluid boundary layer.10-09-2008
20090107513Condom With Multifunctional Coating - Condoms having an elastomeric layer and coating containing an anhydrous warming lubricant and at least one or more ingredients dispersed therein, the coating being disposed on one or both surfaces are provided. The ingredients disposed on the elastomeric layer can be solid particles or encapsulated ingredients that are insoluble in the anhydrous warming lubricant and soluble in water. Methods of producing and using these condoms are also provided.04-30-2009
20090272384Dip-Formed Synthetic Polyisoprene Latex Articles with Improved Intraparticle and Interparticle Crosslinks - A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises soluble sulfur with high S11-05-2009
20100160457Thickened Spreadable Warming Lubricant - A substantially anhydrous, thickened, spreadable, warming lubricant composition comprising a mixture of glycerin, polyhydric alcohol, a non-ionic surfactant, and a Carbomer thickener, the surfactant improving wetting and spreadability of the composition on skin and latex, and the thickener providing a creamy rich feel to the composition, such that the composition can be applied to skin or a condom and provide an optimal warming effect upon contact with ambient moisture during use and such that the composition can be added to a condom package and, over the course of a week, spread and coat nearly the entire internal and external surfaces of the condom.06-24-2010
20100186751Spreadable Warming Lubricant - A substantially anhydrous, spreadable warming lubricant composition comprising a mixture of glycerin, a polyhydric alcohol, and a non-ionic surfactant, the viscosity of the composition being less than that of glycerin but greater than that of the polyhydric alcohol, thereby promoting formation of a useful thin layer on a surface with which the composition is brought into contact, the surfactant improving wetting and spreadability of the composition on skin and latex, such that the composition can be applied to skin or a condom and provide an optimal warming effect upon contact with ambient moisture during use and such that the composition can be added to a condom package and, over the course of about a week, spread and coat nearly the entire internal and external surfaces of the condom.07-29-2010
20100229282Powder-Free Anti-Blocking Coated Glove - Provided herein are powder-free elastomeric articles exhibiting therapeutic properties, and anti-blocking properties. Also provided herein are methods for the manufacture of such articles that are substantially free from interfering materials, as well as packaging means for maintaining therapeutic efficacy.09-16-2010
20100233223Powder-Free Antimicrobial Coated Glove - Provided herein are powder-free elastomeric articles exhibiting good antimicrobial and anti-blocking properties. Also provided herein are methods for the manufacture of such articles substantially free from antimicrobial interfering materials, as well as packaging means for maintaining antimicrobial efficacy.09-16-2010
20100263675Condom with Localized Active Agent - Provided are condoms and methods of making and using the same, the condoms having an elastomeric layer and a low melt wax bead which comprises an active ingredient mixed therein, wherein the bead is affixed on the interior surface of the elastomeric layer in the tip of the condom. Active ingredients can include spermicides such as nonoxynol-9 and vasodilators such as niacin, sildenafil citrate, and nitroglycerin and male desensitizing agents such as benzocaine. The bead can comprise a natural wax in combination with polyethylene glycol or it can be a polyethylene glycol-based wax. The exterior surface of the elastomeric layer is substantially free of the active ingredient.10-21-2010
20110088140Latex gloves and articles with geometrically defined surface texture providing enhanced grip and method for in-line processing thereof - Latex articles with geometrically defined surface structure providing enhanced grip characteristics in dry, wet or oily environment; and a method of making same comprising applying a polymeric coagulant coating to a smooth former surface, wherein the coating becomes tacky during drying, applying discrete coagulant particles of selected size, shape and distribution to the tacky coating to attach and protrude from the former surface with the polymeric coagulant coating, dipping the former into an aqueous latex emulsion, wherein the polymeric coagulant coating and the discrete coagulating particles destabilize the latex, thereby developing a latex layer, vulcanizing and stripping the latex article inside out, and dissolving the discrete coagulant particles in water or suitable solvents to reveal the geometrically designed texture with pre-selected size, shape and distribution of impressions providing improved dry, wet and oily surface grip by removal of a fluid boundary layer.04-21-2011
20110145975P0WDER-FREE GLOVE WITH STABLE AND FAST ACTING MICROBIAL COATING - Provided, among other things, is a elastomeric medical glove having an antimicrobial surface coating comprising: a polymeric layer, and a dried, non-tacky coating on a surface of the polymeric layer, the coating comprising an antimicrobial agent, a wax agent, a lubricant, and a water-soluble wetting agent; wherein the glove comprises a residual powder of less than 2 mg per glove.06-23-2011
