- 7. A rolled condom according to claim 6, wherein at least 50% of the area of the internal surfaces of said condom, extending proximally from the distal end, has said coefficient of friction, while the condom is in said rolled-up condition.
- 8. A rolled condom according to claim 1, wherein the exterior surface of at least said distal portion of said sheath is coated with a friction-reducing substance, and said friction-reducing substance has been inhibited from transfer to the internal surfaces of the sheath by application of a removable protective outer layer prior to said sheath having been rolled up upon itself.
- 9. A rolled condom according to claim 1, wherein said sheath, when unrolled, is elongated and has a diameter which increases generally uniformly in the proximal direction along at least a portion of its axial length.
- 10. A rolled condom according to claim 1, wherein said sheath, when unrolled, is, in the proximal direction, generally cylindrical and of generally uniform diameter to at least the proximal end of said distal portion, but which increases in diameter in the proximal direction, along at least a portion of the axial length of the condom.
- 11. A rolled condom according to claim 1, wherein the interior surface of said generally hemispherical closed, distal end is provided with a material for adhering said closed, distal end of the condom to the distal end of a penis, a material for absorbing pre-ejaculatory secretions from a penis, or a combination of said materials.
- 12. A rolled condom according to claim 1 which further comprises:
- a cap-like secondary layer superposed upon a distal portion of the outer surface of said sheath and covering approximately at least the tip of the distal end but no more than about the distal third of said sheath, and
- a liquid lubricant, medicament, biocide, or combination thereof enclosed within at least some of the space between said secondary layer and the outer surface of said sheath.
- 13. A rolled condom according to claim 1, wherein the sheath has a wall thickness which is less than 0.15 mm.
- 14. A rolled contraceptive condom for a human penis in a rolled-up condition suitable for packaging, comprising:
- a sheath having, in the unrolled condition, a generally hemispherical closed, distal end, a generally tubular distal portion extending proximally from said closed distal end, and an open, proximal end, the generally tubular distal portion extending proximally to surround and fictionally engage an erect human penis when the condom is unrolled, said sheath having been rolled up outwardly upon itself, from said proximal end toward said distal end, the interior surfaces of at least said generally tubular distal portion having deposited thereon a friction-enhancing substance, being substantially free of measurable tack at an ambient temperature of about 40.degree. C. and having, while the condom is in said rolled-up condition, a coefficient of static friction, as determined by ASTM Designation D 1894-90, which is >0.70.
- 15. A rolled condom according to claim 14, wherein the outermost surface of at least the distal portion is sufficiently non-blocking to prevent adherence to interior surfaces when the condom is rolled up.
- 16. A rolled condom according to claim 14, wherein said coefficient of static friction is at least about 1.0.
- 17. A rolled condom according to claim 15, wherein the outermost surface of at least said distal portion comprises a coating comprising an anti-blocking material deposited on said outermost surface of at least said distal portion, and said anti-blocking material is sufficiently adhered to said outermost surface to substantially prevent transfer of said anti-blocking material to the interior surfaces of said condom when said condom is rolled up or unrolled.
- 18. A rolled condom according to claim 14, wherein said distal portion of said condom is at least one-fourth of the unrolled length of said condom.
- 19. A rolled condom according to claim 18, wherein at least 50% of the area of the internal surfaces of said condom, extending proximally from the distal end, has said coefficient of friction, while the condom is in said rolled-up condition.
- 20. A rolled condom according to claim 14, wherein the exterior surface of at least said distal portion of said sheath is coated with a friction-reducing substance, and said friction-reducing substance has been inhibited from transfer to the internal surfaces of the sheath by application of a removable protective outer layer prior to said sheath having been rolled up upon itself.
- 21. A rolled condom according to claim 14, wherein said sheath, when unrolled, is, in the proximal direction, generally cylindrical and of generally uniform diameter to at least the proximal end of said distal portion, but which increases in diameter in the proximal direction, along at least a portion of the axial length of the condom.
- 22. A rolled condom according to claim 14, wherein the interior surface of said generally hemispherical closed, distal end is provided with a material for adhering said closed, distal end of the condom to the distal end of a penis, a material for absorbing pre-ejaculatory secretions from a penis, or a combination of said materials.
- 23. A rolled condom according to claim 1 which further comprises:
- a cap-like secondary layer superposed upon a distal portion of the outer surface of said sheath and covering approximately at least the tip of the distal end but no more than about the distal third of said sheath, and
- a liquid lubricant, medicament, biocide, or combination thereof enclosed within at least some of the space between said secondary layer and the outer surface of said sheath.
- 24. A rolled condom according to claim 14, wherein the sheath has a wall thickness which is less than 0.15 mm.
- 25. A rolled contraceptive condom for a human penis in a rolled-up condition suitable for packaging, comprising:
- a sheath having, in the unrolled condition, a generally hemispherical closed, distal end, a generally tubular distal portion extending proximally from said closed distal end, and an open, proximal end, the generally tubular distal portion extending proximally to surround and fictionally engage an erect human penis when the condom is unrolled, said sheath having been rolled up outwardly upon itself, from said proximal end toward said distal end, the interior surfaces of at least said generally tubular distal portion having a friction-enhancing pattern thereon, being substantially free of measurable tack at an ambient temperature of about 40.degree. C., and having, while the condom is in said rolled-up condition, a
- coefficient of static friction, as determined by ASTM Designation D 1894-90, which is >0.70, said coefficient of static friction being provided by said friction-enhancing pattern on said interior surfaces of at least said generally tubular distal portion.
- 26. A rolled condom according to claim 25, wherein the outermost surface of at least the distal portion is sufficiently non-blocking to prevent adherence to interior surfaces when the condom is rolled up.
