Abstract

A condom retainer ring structure (20) is for use on a condom (10) that has an elongated thin walled tubular sheath of resilient material closed at one end and opened at the other end, with a bead surrounding the opening. The condom retainer ring structure has a first ring (22) for positioning at the periphery of the opening, adjacent the bead that surrounds the sheath. A second ring (24) is connected to and adjacent the first ring. A bridge (26) having a retention notch (28) therein joins the rings generally in a single unflexed condition. In use, when a condom (10) is worn on the penis of a user, the first ring (22) surrounds the sheath on the shaft of the penis, the second ring (24) encircles the scrotum to anchor the condom, and the bridge (26) is flexed thereby, constricting the retention notch (28). The retention notch (28), preferably positioned over the bead of the condom, grabs the bead to retain the condom.

Claims

AMENDED CLAIMS [received by the International Bureau on 17 April 1995 (17.04.95); original claims 1-18 replaced by amended claims 1-8 (2 pages)]

1. A combination of a condom and a condom retainer structure, the combination comprising:

a single-piece retainer ring structure including a first ring surrounding said sheath; a second ring adjacent said first ring; and

a bridge joining said first ring with said second ring, said bridge including retention means for retaining said retainer ring structure in a fixed position relative to said bead;

wherein said bridge is attached to said bead by said retention means, said retention means grabs said bead, and said retention means is a notch.

2. The combination of claim 1, wherein said notch is constricted when said first ring and said second ring are flexed toward one another.

3. The combination of claim 1, wherein said notch is constricted when said bridge is flexed.

4, A single-piece retainer ring structure for wearing on the penis and scrotum of a male wearer, the structure comprising:

a first ring for encircling the penis;

a bridge joining said first ring with said second ring, said first and second rings and said bridge being integrally formed as a single-piece retainer ring structure and being disposed generally in a plane when said retainer ring structure is in a relaxed state;

wherein said bridge includes retention means carried by said bridge for grabbing a bead defined adjacent an open end on a condom, wherein said retention means is formed in said bridge and wherein said retention means is a notch.

5. The retainer ring structure of claim 4, wherein said notch is constricted when said first ring and said second ring are flexed toward one another.

6. The retainer ring structure of claim 4, wherein said notch is constricted when said bridge is flexed.
