DESCRIPTION:
BRIEF SUMMARY
This application is a national stage application, according to Chapter II of the Patent Cooperation Treaty. This application claims the priority date of Aug. 28, 1992 for French Patent No. 92 10353.
The present invention relates to a securing and protective rigid disc for a condom, the peripheral edge of said disc being designed to be introduced under the rolled bead of the sheath, said disc being positioned on the upper end and on the outside of the sheath.
A condom provided with such a disc has been disclosed in the BABLED French patent application No. 90-05994 filed on May 14, 1990. It is essentially a question of a flat disc. Its object is to avoid that the preservative be erroneously put by a user in the wrong direction. The object of such a disc is even to prevent pathogenic germs to be transmitted by the user to his partner when he puts the condom in the right direction after a first attempt when, positioning it in the wrong direction, he has put the normal outside end of the preservative into contact with the glans of his penis. This kind of disc has therefore a double function: it is a securing and protective disc.
The object of the present invention is to improve such a disc, particularly by making safer its bearing in the bead of the condom up to the moment immediately preceding its positioning, this while allowing a very easy ejection of the disc, needing no intervention of the user, this ejection automatically happening at the very beginning of the putting in place.
To this end, the present invention relates to a protective rigid disc for a condom, said disc presenting on its peripheral edge a flat flange designed to be engaged under the rolled bead of the sheath, said disc being positioned on the upper end and on the outside of said sheath, characterized in that said flange surrounds a part of the disc which presents towards the outside a protrusion extending above the plane of said flange.
This protrusion cooperates, together with the flange, to the centering and positioning of the disc in the bead of the sheath. This protrusion extending towards the outside with respect to the plane of the flange, will also allow the user to immediatly realize by touch, even in the darkness, whether he holds the condom in the right position, or if he must turn it inside out before putting it in place.
The protrusion of the disc can take all the possible shapes, allowing it to fulfil the same functions. Said protrusion can particularly consist of a skirt forming a lateral backing for the bead, this skirt having for example a height of 4-5 mm. The protrusion in question could also be constituted of a hood convex towards outside, that is to say a kind of dome having the shape of a sphere or similar, the base of which would connect to the flange. The protrusion of the disc can also consist both of the skirt and of said convex hood, in which case the hood, advantageously connected, by its peripheral edge, to the base of the skirt, can have essentially the same height as this skirt, or be slightly higher than this one; therefore, the hood will be able, in such a case, to appear slightly in protrusion above the edge of the skirt, and so to cooperate for helping the user to recognize by touch the right direction of positioning.
As concerns the flange, that is to say the flat part of the disc which extends all around said protrusion, it will have any width and shape allowing it to be sufficiently inserted under the bead of the condom in order that the disc does not risk to escape from it by chance in the packing, or prematurely before the instant immediatly preceding the positioning onto the penis. To this end, the width of the flange can be of about 1.2-2.5 mm, these values being given only as an indication.
If in a plan view the disc has a circular shape, as this will be the most current case, the skirt will also have a circular shape, so that the flange, itself also circular in shape, will have a constant width. This flange can be continuous or interrupted. In that case, it can be constituted for example of a ser
