Abstract: A molded glove defines a hand and wrist portion, with the wrist portion defining, in as-molded configuration, longitudinal channels positioned about its circumference. In accordance with this invention, a plurality of circumferential channels are defined on the wrist portion at the end remote from the hand portion, the circumferential channels crossing the longitudinal channels. The thickness of the glove along the longitudinal and circumferential channels is increased over the thickness of the glove in areas adjacent to the channels. The glove exhibits improved resistance to rolling down of the cuff while being worn, when compared with conventional gloves having longitudinal flutes or channels, gloves having beaded cuffs, and the like.

Abstract: A pair of rubber gloves of the conventional thin, limp, rubber material used by surgeons, house-wives, etc. and each having an elongated hand portion and an elongated, integral cuff portion are each sleeved within the flexible, limp resilient cuff portion with a hollow, normally open circular-ended, substantially cylindrical, support of self-supporting sheet material such as cardboard or plastic. The hand portion is compressed within the inner portion of the support for storage and shipment and the support may be truncated conical for nesting or may be compressed to oval-ended configuration for packaging. The support may have an enlarged integral bead at each end.

Abstract: In the coating of rubber surfaces with adherent slip coatings the need for release agents is avoided by selecting as the slip coating a synthetic polymer latex composition consisting essentially of about 5 to 95% by weight of a film-forming, non-elastomeric synthetic polymer component (1) having an elongation of at least about 200% and about 5 to 95% of a normally solid, non-elastomeric, synthetic polymer component (2) exhibiting an elongation of below about 20% and a coefficient of friction of up to about 0.20, said slip coating having an elongation of at least about 200 up to 700%, a coefficient of friction of up to about 0.25 and a thickness of below about 0.005 inch.

Abstract: A medical glove adapted to tightly conform to a wearer's skin and to be donned without the use of additional lubricants is formed with an outer layer of elastomeric material, an inner layer of elastomeric material bonded to the outer layer and particulate matter securely embedded in and randomly distributed throughout the inner layer. The particulate matter is preferably partially exposed on the inner, skin-contacting surface of the inner layer so that it extends inwardly beyond the surface of the inner layer to provide a lubricating means to facilitate donning of the glove without the use of additional lubricants. A method for making the unique medical glove is also disclosed.

Abstract: Natural or synthetic rubber surgical elements such as tubing, catheters, drains and gloves are "lubricated" so as to prevent sticking during storage, and permit easier emplacement, such as putting on the gloves by a surgeon or nurse, by applying to the surface of the rubber elementA finely divided biodegradable powder consisting essentially ofAn enzymatically degradable form of poly(N-acetyl-D-glucosamine) selected from the group consisting ofPoly[N-acetyl-6-O-(carboxymethyl)-D-glucosamine],Poly[N-acetyl-6-O-(2'-hydroxyethyl)-D-glucosamine],Poly[N-acetyl-6-O-(ethyl)-D-glucosamine], andPoly(N-acetyl-D-glucosamine) itselfThis powder is readily absorbed by living tissue without deleterious tissue reaction, thus minimizing tissue reaction from the transfer of the powder from the element such as a glove to internal sites in a subject. The gloves may be packaged in a strippable laminate package. The polymers are derived from chitin.

Abstract: There is described a method of manufacturing silicone rubber gloves with a non-blocking surface by repeatedly dipping a form in a solvent dispersion of uncured silicone rubber to build up a plurality of layers and then forming a layer of liquid droplets on the surface of the solvent-containing uncured rubber, thereby forming a textured surface as the solvent evaporates.

Abstract: A uniquely contoured glove adapted to tightly conform to a wearer's hand is made by depositing an elastomeric material on a relatively flat glove form having recessed areas covering substantially the entire surface of the hand-forming and finger-forming portions of the form except for a peripheral edge surrounding the recessed areas. The resulting glove, when stripped from the form and reversed, has a hand portion, an open end cuff portion and a plurality of elongated finger-receiving compartments, each of said compartments and said hand portion having a transverse cross-sectional configuration formed by four outwardly curved sections connected by four inwardly curved sections.

Abstract: An article comprising a rubber surface provided with an adherent slip coating of a synthetic polymer latex composition consisting essentially of about 5 to 95% by weight of a film-forming, non-elastomeric synthetic polymer component (1) having an elongation of at least about 200% and about 5 to 95% of a normally solid, non-elastomeric, synthetic polymer component (2) exhibiting an elongation of below about 20% and a coefficient of friction of up to about 0.20, said slip coating having an elongation of at least about 200 up to 700%, a coefficient of friction of up to about 0.25 and a thickness of below about 0.005 inch.

Abstract: A method of treating a surface of an extensible hydrocarbon article by positioning the article in a chamber from which extraneous oxidizing agents are excluded, extending the article, and treating the extended surface with a fluorinating gas which may contain elemental fluorine or a mixture of same with an inert gas such as nitrogen. The treatment provides improved frictional characteristics, chemical inertness, and other desirable properties.

Abstract: An examining glove at least one finger of which is inverted and has a rupturable seal to form a lubricant containing space. The arrangement is such so that when the glove is put on the seal is ruptured and the exterior of the glove finger is lubricated.

Abstract: Method for applying an elastic band around the cuff of an elastic glove which includes extruding a stripe of elastomeric material around the cuff of the glove while on a glove form and curing the stripe. A tray carrying a row of glove forms, each having a glove thereon, is stopped to position one of the forms at a band applying station. A mast having an extruder nozzle adjacent the cuff edge is moved circumferentially about the cuff in a generally elliptical path to avoid engagement with adjacent forms while allowing the forms to be closely spaced for economical manufacturing.

Abstract: Rubber articles, such as surgeon's gloves, are provided with a synthetic resin slip coating by contacting the rubber surface with a synthetic resin latex composition. The slip coating is adherent to the rubber substrate and is very extensible without adverse effect. The synthetic resin slip coating includes from 5 to 90 percent by weight of a first resin copolymer component selected from the group consisting of vinyl chloride-alkyl acrylate copolymer, vinylidene chloride-alkyl acrylate copolymer, and vinyl acetate-alkyl acrylate copolymer, and correspondingly, from 95 to 10 percent by weight of a second resin copolymer component selected from the group consisting of vinyl chloride-vinyl ester copolymer, and vinylidene chloride-vinyl ester copolymer.
