Abstract
Abstract A pubic shield is provided having an elastic tubular sheet attached to a substantially frusto-conical structure at the relatively smaller diameter of the frusto-conical structure. The frusto-conical structure forms a shield member having substantially two stable positions, a storage position and a use position. The shield member is in the use position when the tubular sheet extends away from the frusto-conical member. Use of the pubic shield, alone or with a bioadhesive, provides an enhanced prophylactic effect over that of a typical condom.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
195 words
An improved condom having a two-position public pubic area shield comprising: an elastic, elongated tubular penis enclosing member having a longitudinal axis, an inner surface, an outer surface, an open proximal end, and a closed distal end; a generally frusto-conically configured, self-supporting, resilient pubic area shield member having opposed first and second side surfaces and a central aperture defined therein whose diameter approximates the diameter of said proximal end, and having a peripheral rim in radially and diagonally outwardly spaced relationship to said aperture; annular flexible joining means interconnecting said proximal end with said shield member circumferentially about said aperture whereby said first surface is generally coextensive with said outer surface, and said second surface is generally coextensive with said inner surface; said shield member being longitudinally invertable about said annular joining means from a first stable configuration to a second stable configuration; said first configuration corresponding to a storage configuration wherein said tubular member, when longitudinally collapsed, is generally nestably receivable with said shield means; said second configuration corresponding to a use configuration wherein said tubular member, when extended, projects away from said shield member; and said second surface being provided with a bioadhesive.
Claim 2
Dependent Claim
195 words
An improved condom having a two-position public pubic area shield comprising: an elastic, elongated tubular penis enclosing member having a longitudinal axis, an inner surface, an outer surface, an open proximal end, and a closed distal end; a generally frusto-conically configured, self-supporting, resilient pubic area shield member having opposed first and second side surfaces and a central aperture defined therein whose diameter approximates the diameter of said proximal end, and having a peripheral rim in radially and diagonally outwardly spaced relationship to said aperture; annular flexible joining means interconnecting said proximal end with said shield member circumferentially about said aperture whereby said first surface is generally coextensive with said outer surface, and said second surface is generally coextensive with said inner surface; said shield member being longitudinally invertable about said annular joining means from a first stable configuration to a second stable configuration; said first configuration corresponding to a storage configuration wherein said tubular member, when longitudinally collapsed, is generally nestably receivable with said shield means; said second configuration corresponding to a use configuration wherein said tubular member, when extended, projects away from said shield member; and said second surface being provided with a bioadhesive.
Claim 3
Dependent Claim
11 words
The condom of claim 1 wherein said bioadhesive includes a biocide.
Claim 4
Dependent Claim
45 words
The condom of claim 2 wherein said annular joining means is more rigid than said tubular member and said shield member and is positioned so that said annular joining means is displaced toward said longitudinal axis when said shield member is in said use configuration.
Claim 5
Dependent Claim
18 words
The condom of claim 1 wherein said shield member is provided with an arcuate cut-out in said rim.
Claim 6
Dependent Claim
10 words
The condom of claim 1 contained in a sealed envelope.
Claim 7
Dependent Claim
134 words
A snap-over, two-position pubic area shield comprising: a generally frusto-conically configured self-supporting, resilient pubic area shield member having opposed side surfaces and a central aperture defined therein with aperture edge portions, and having a peripheral rim in radially and diagonally outwardly spaced relationship to said aperture, a penis-receiving tubular boss having an inner surface, an outer surface, an open proximal end, and an open distal end, said proximal end being circumferentially integrally formed with said aperture edge portions, said shield member being invertable about said aperture edge portions from a first stable configuration to a second stable configuration, said first configuration corresponding to a storage configuration wherein said tubular boss is circumscribed by said shield member, said second configuration corresponding to a use configuration wherein said tubular boss projects away from said shield member.
Claim 8
Dependent Claim
134 words
A snap-over, two-position pubic area shield comprising: a generally frusto-conically configured self-supporting, resilient pubic area shield member having opposed side surfaces and a central aperture defined therein with aperture edge portions, and having a peripheral rim in radially and diagonally outwardly spaced relationship to said aperture, a penis-receiving tubular boss having an inner surface, an outer surface, an open proximal end, and an open distal end, said proximal end being circumferentially integrally formed with said aperture edge portions, said shield member being invertable about said aperture edge portions from a first stable configuration to a second stable configuration, said first configuration corresponding to a storage configuration wherein said tubular boss is circumscribed by said shield member, said second configuration corresponding to a use configuration wherein said tubular boss projects away from said shield member.
Claim 9
Dependent Claim
14 words
The snap-over pubic shield in accordance with claim 6 contained in a sealed envelope.
Claim 10
Dependent Claim
23 words
The snap-over pubic shield in accordance with claim 6 wherein said frusto-conical shield member is provided with an arcuate cut-out in said rim.
Claim 11
Dependent Claim
21 words
The snap-over pubic shield in accordance with claim 6 wherein said tubular boss is provided with a ribbed said outer surface.
Claim 12
Dependent Claim
18 words
The snap-over pubic shield in accordance with claim 9 wherein an adhesive is present on said ribbed surface.
Claim 13
Dependent Claim
24 words
The snap-over pubic shield in accordance with claim 6 wherein said tubular boss is provided with a reduced diameter at said distal end thereof.
Claim 14
Dependent Claim
20 words
The snap-over pubic shield in accordance with claim 6 wherein said tubular boss has an outwardly flared said distal end.
Claim 15
Dependent Claim
23 words
The snap-over pubic shield in accordance with claim 6 wherein said tubular boss defines an outer peripheral groove at said proximal end thereof.
Claim 16
Dependent Claim
23 words
The snap-over pubic shield in accordance with claim 6 wherein said tubular boss defines an inner peripheral groove at said proximal end thereof.
