Claims12
A mandrel for forming condoms, said mandrel comprising:
- an elongate body having a proximal end, a distal end and a substantially cylindrical shaft portion therebetween;
- a plurality of grooved recesses extending along two different directional planes in the surface of the mandrel for creating an interlocking micromesh ribbing pattern on a surface of the condom;
- and
- said plurality of grooved recesses extending along at least a portion of the area in the surface of said mandrel between the distal and proximal ends.
A method of making a condom using a mandrel having an elongate body having a proximal end, a distal end and a substantially cylindrical shaft portion therebetween, a plurality of grooved recesses extending along two different directional planes in the surface of the mandrel for creating an interlocking micromesh ribbing pattern on a surface of the condom, and the plurality of grooved recesses extending along at least a portion of the area in the surface of the mandrel between the distal and proximal ends, said method comprising the steps of:
- immersing said mandrel into a reservoir of a solution of elastomeric material for a sufficient time;
- withdrawing said mandrel with the elastomeric material from said reservoir adhered thereon;
- curing said elastomeric material agent for yielding a solidified elastomeric material with desired physical properties;
- and
- removing said solidified elastomeric material from said mandrel.
