Methods for Making Male Condom of Self-standing Skirt Structure etc

An alternative method for making male condom of self-standing skirt structure, a skirt-supporting thickened belt-like ring coming together with said skirt structure and located at the root area of said condom, a rim at the middle line of the condom body, comprising the steps of:

• adding a taper shape structure onto the bottom of conventional condom mold;
• lowering down a mold cover being split into upper and lower two parts to cover said condom mold, with said taper shape structure, the root area of said condom mold and the middle line of said condom mold are being exposed and uncovered;
• rotating said mold cover around said mold;
• using nozzles on said rotating mold cover to evenly spray coagulant onto said taper shape structure, the root area of said condom mold and the middle line of said condom mold;
• raising up and taking back said mold cover;
• drying said mold in a drying oven;
• dipping said condom mold into a dipping trough and then following conventional condom dipping workmanship.

Another alternative method for making male condom of self-standing skirt structure, a skirt-supporting thickened belt-like ring coming together with said skirt structure and located at the root area of said condom, a rim at the middle line of the condom body, comprising the steps of:

• making the thin and soft condom body using conventional one time dipping workmanship;
• making the thicker and harder self-standing skirt structure together with said thickened belt-like ring at the root area of said condom using twice or multiple dipping workmanship or injection or extruding etc workmanship;
• connecting the thin and soft condom body and the thicker and harder self-standing skirt structure together with said thickened belt-like ring at the root area of said condom using heat-melting, ultrasonic-melting, high frequency melting or glue sticking etc methods;
• melting or sticking a rubber rim at the middle line of the condom body.

A further alternative method for making male condom of self-standing skirt structure, a skirt-supporting thickened belt-like ring coming together with said skirt structure and located at the root area of said condom, a rim at the middle line of the condom body, comprising the steps of:

• making said condom body together with the skirt structure using conventional one time latex dipping workmanship or polyurethane forming workmanship;
• melting or sticking a big elastic plastic loop onto the outer edge of said skirt structure to stretch out said skirt structure to make it self-stand;
• melting or sticking a thickened belt-like ring onto the root area of said condom;
• melting or sticking a rubber rim at the middle line of the condom body.

A male condom, comprising:

• a sperm reservoir at the closing end of the condom;
• a tubular condom body;
• wherein said condom body is of:
• a rigid and thicker self-standing skirt structure of the same material of the condom body at the open end of the condom body and being seamlessly connected with the condom body via a belt-like ring;
• a skirt-supporting thickened belt-like ring coming together with said skirt structure and located at the root area of said condom body;
• a rim at the middle line of said condom body serving as the starting axis to roll up the condom when said condom body being folded in half;
• in the meantime the tubular condom body reserves its conventional thinness and softness.

An automated auxiliary equipment being added onto conventional latex dipping producing line to treat condom molds in lots before it can produce a condom of different thickness and hardness in its different parts in same one action, comprising:

• a condom mold cover being split into several parts in a similar shape of condom mold but larger than condom mold to cover said condom mold;
• mechanical arms to move the condom mold cover parts to cover or uncover said condom mold;
• spray nozzles;
• pipes to connect said nozzles with storage tank of coagulant;
• metal structure to hang equipment parts around condom mold;
• gearing to convey condom molds onto and away from treatment assembly;
• motor(s) to drive the assembly;
• pump to transfer coagulant from the storage tank to spray nozzles;
• sensors to position the location of said condom molds;
• PLC module or micro-processor to control said assembly;
• elastic supporter in both sides of said assembly to balance and amortize condom molds groups.

A method for rolling up and pack said male condom, comprising the steps of:

• raising up said skirt structure till said male condom being folded in half with the sperm reservoir of said condom standing upwardly;
• blowing compressed air downward between the two layers of the folded condom till the rim at the middle line of the condom body level off, grasping the rim now on the bottom of folded condom;
• putting said condom onto a rod of the condom rolling equipment;
• coiling said condom with the rim serving as the starting axis till the roll reaching the bottom of the self-standing skirt structure;
• packing the rolled up condom in a conventional means.
