View Patent ↗A method of making a sponge device is provided. This method includes introducing a curable liquid sponge forming material into a form, placing a handle into the material before it is fully cured, heating the form to cure the material, removing the cured material from the form, and rinsing the cured material. Another aspect of the present invention is the assembly for making this sponge device. This assembly includes a runner for joining a plurality of handles, plates that are spring-biased together to support the handles, a chase formed of heat conductive metal having a shelf where the plates can be set, and a silicone form having a plurality of cavities therein for receiving the sponge forming material.
1. A method of manufacturing a sponge device, comprising:
providing a form having a plurality of cavities therein;
introducing a curable liquid sponge forming material into said cavities of said form;
placing a handle partially into said material in a plurality of said cavities before said material is fully cured;
heating said form and said material therein to cure said material, wherein said material forms a sponge around part of said handle to form a plurality of said devices;
removing said devices from said form;
rinsing said sponge in an aqueous solution;
rinsing said sponge in a solution comprised of glycerin; and
providing a runner for joining a plurality of said handles together during all of said steps commencing with said placing step.
2. The method of claim 1 , further comprising:
