ABSTRACT:
A condom with improved adhesivity and a method for manufacturing same includes the steps of placing a pre-rolled condom on a distal end of a tubular fixture, unrolling the condom towards a proximal end of the tubular fixture leaving a rolled portion equal to a distance X+Y, holding the condom a distance X from the rolled portion using a flexible ring-shaped holding fixture forming a first portion, folding the first portion over the flexible ring-shaped holding fixture so that the rolled portion is placed a distance X from the flexible ring-shaped holding fixture, applying an adhesive layer on the folded first portion between the rolled portion and the flexible ring-shaped holding fixture, unrolling the rolled portion a distance X over the first portion having the adhesive layer thereon forming a ply portion and a distance Y over the tubular fixture, thereby completely unrolling the rolled portion, removing the flexible ring-shaped holding fixture, and rolling the condom back fully towards the distal end of the tubular fixture. The condom with improved adhesivity includes an elongated hollow tubular condom body closed at a distal end and made of a flexible material, wherein a proximal end of the tubular body includes a ply portion with an adhesive layer therebetween, and wherein the ply portion is followed to an opening in the proximal end by a final portion without adhesive, whereby when the final portion is pulled during application the ply portion is unfolded resulting in the adhesive layer being positioned between the condom body and the penis of the user.
