Contraceptive sheath - has axially spaced circumferential constructions for better grip and no leakage

摘要

Sheath has a closed end to cover the glans penis and with a pouch projecting from the end, axially spaced upper and lower constrictions, and hollow projections on the sheath adjacent to the constrictions with the end of each projection having a dimple. The walls of the constrictions are pref. concave and extend around the whole circumference of the sheath. The projections are pref. present between the closed end and upper constriction, between the constrictions and over the lower constriction. The arrangement reduces the risk of the sheath slipping off in use or of leakage of semen.
