ABSTRACT:
A rollable condom having a retention periphery at the open end (28) of an elongated tubular sheath (20). The open end (28) is a discontinuous periphery that communicates with a discontinuous bead (22)at its edge. The periphery becomes discontinuous at a notch (34). A hole (32) is located opposite the notch (34) within the sheath wall (38) along the bead (22). The hole (34) has an indentation (24) which is centered on the hole (32) toward the closed end (30) of the sheath (20). Located within the sheath (20) is an inner seal (36) which communicates with and protrudes from the sheath wall (38) to extend forward toward the closed end (30) of the sheath (20) to form a circumference of smaller diameter than the tubular sheath (20). When the sheath (20) is fully unrolled onto the penis, and the scrotum is positioned through the hole (32), a retention periphery is created which provides support to the scrotum in achieving increased physical contact during use.
