Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 145 words
Prophylactic apparatus comprising, means defining an outer sheath in the form of a thin rubber tube closed at one end and open at the other and an inner sheath of thin rubber open at both ends, and means for establishing liquid sealing relationship between said inner and outer sheaths near the open end of said outer sheath to form at least a double wall near said open end with the region between defining a reservoir for retaining fluids originating between the inner opening of said inner sheath and the closed end of said outer sheath while the region on the inside of said inner sheath remains essentially dry, said inner sheath inside said outer sheath being secured to said outer sheath at a plurality of locations to form a double wall with means for receiving and limiting the travel of fluids produced inside said apparatus.
Claim 2
Dependent Claim 145 words
Prophylactic apparatus comprising, means defining an outer sheath in the form of a thin rubber tube closed at one end and open at the other and an inner sheath of thin rubber open at both ends, and means for establishing liquid sealing relationship between said inner and outer sheaths near the open end of said outer sheath to form at least a double wall near said open end with the region between defining a reservoir for retaining fluids originating between the inner opening of said inner sheath and the closed end of said outer sheath while the region on the inside of said inner sheath remains essentially dry, said inner sheath inside said outer sheath being secured to said outer sheath at a plurality of locations to form a double wall with means for receiving and limiting the travel of fluids produced inside said apparatus.
Claim 3
Dependent Claim 27 words
Prophylactic apparatus in accordance with claim 1 wherein said inner sheath extends inside said outer sheath for a short distance of between substantially 1 and 5 inches.
Claim 4
Dependent Claim 36 words
Prophylactic apparatus in accordance with claim 1 wherein said inner sheath extends inside said outer sheath so that the innermost edge of the inner sheath rests against the penis closely behind the edge of the glans.
Claim 5
Dependent Claim 88 words
Prophylactic apparatus in accordance with claim 1 wherein said inner sheath is shorter than said outer sheath and bonded thereto along a narrow circumferential band of the order of 2 to 5 inches from the outer sheath closed end and extends for of the order of between 1 and 4 inches over part of which distance the inner and outer sheaths are bonded together along a plurality of narrow axial bands extending from positions near said circumferential band to positions adjacent the innermost edge of the inner sheath.
Claim 6
Dependent Claim 43 words
Prophylactic apparatus in accordance with claim 1 wherein the innermost part of the inner sheath tapers to a diameter at its innermost edge that is significantly smaller than the diameter of the outer sheath for firmly engaging the penis directly behind the glans.
Claim 7
Dependent Claim 18 words
Prophylactic apparatus in accordance with claim 1 wherein the innermost edge of the inner sheath is lightly reinforced.
Claim 8
Dependent Claim 19 words
Prophylactic apparatus in accordance with claim 1 wherein the innermost edge of the inner sheath has a feather edge.
Claim 9
Dependent Claim 17 words
Prophylactic apparatus in accordance with claim 1 wherein said apparatus is made of one piece of rubber.
Claim 10
Dependent Claim 38 words
Prophylactic apparatus in accordance with claim 8 wherein said apparatus is folded inside and under to form said inner sheath that extends toward said closed end for a distance of the order of between 2 and 6 inches.
Claim 11
Dependent Claim 40 words
Prophylactic apparatus in accordance with claim 1 wherein said inner sheath extends inside said outer sheath with the innermost edge of the inner sheath extending to within the order of 1.5 inches from the closed end of the outer sheath.
Claim 12
Dependent Claim 75 words
Prophylactic apparatus in accordance with claim 1 wherein said inner and outer sheaths are bonded together at a plurality of small bonded areas located substantially uniformly over the area extending from a location of the order of 0.5 inch from said liquid sealing relationship between said inner and outer sheath near said open end of said outer sheath to a location of the order of 0.125 inch from said inner opening of said inner sheath.
Claim 13
Dependent Claim 41 words
Prophylactic apparatus in accordance with claim 1 wherein the inner opening of said inner sheath has a plurality of narrow pigtails that extend toward said closed end of said outer sheath and at their ends are secured to said outer sheath.
