Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
A medical glove adapted to tightly conform to the skin of a wearer's hand and to be donned without the use of additional lubricants, comprising: an outer layer of elastomeric material; an inner layer of elastomeric material comprising as a major component thereof carboxylated styrene butadiene latex bonded to said outer layer; and corn starch particles securely embedded in and randomly distributed throughout said inner layer, at least a portion of said particles having a size greater than the thickness of said inner layer and at least a portion of said particles being partially exposed on the inner, skin-contacting surface of said inner layer to form a lubricating means for aiding in the donning of said glove.
Claim 2
Dependent Claim
117 words
A medical glove adapted to tightly conform to the skin of a wearer's hand and to be donned without the use of additional lubricants, comprising: an outer layer of elastomeric material; an inner layer of elastomeric material comprising as a major component thereof carboxylated styrene butadiene latex bonded to said outer layer; and corn starch particles securely embedded in and randomly distributed throughout said inner layer, at least a portion of said particles having a size greater than the thickness of said inner layer and at least a portion of said particles being partially exposed on the inner, skin-contacting surface of said inner layer to form a lubricating means for aiding in the donning of said glove.
Claim 3
Dependent Claim
117 words
A medical glove adapted to tightly conform to the skin of a wearer's hand and to be donned without the use of additional lubricants, comprising: an outer layer of elastomeric material; an inner layer of elastomeric material comprising as a major component thereof styrene-polyethylene butylene-stryene block copolymer bonded to said outer layer; and corn starch particles securely embedded in and randomly distributed throughout said inner layer, at least a portion of said particles having a size greater than the thickness of said inner layer and at least a portion of said particles being partially exposed on the inner, skin-contacting surface of said inner layer to form a lubricating means for aiding in the donning of said glove.
Claim 4
Dependent Claim
117 words
A medical glove adapted to tightly conform to the skin of a wearer's hand and to be donned without the use of additional lubricants, comprising: an outer layer of elastomeric material; an inner layer of elastomeric material comprising as a major component thereof styrene-polyethylene butylene-stryene block copolymer bonded to said outer layer; and corn starch particles securely embedded in and randomly distributed throughout said inner layer, at least a portion of said particles having a size greater than the thickness of said inner layer and at least a portion of said particles being partially exposed on the inner, skin-contacting surface of said inner layer to form a lubricating means for aiding in the donning of said glove.
