  • Patent number: 5869437
    Abstract: A transparent cleansing bar having a logo or other design or message printed on a dissolvable polymer material embedded at approximately the mid-point of the bar. The message is printed on both sides of a very thin sheet of dissolvable plastic material. The bar is formed from transparent modified soap material. The printed sheet is positioned between the two halves of the bar which form the transparent bar having the printed message at the midpoint. The message is viewable through the transparent bar. Upon normal use, the surface of the bar wears away. When the bar is worn or wasted to the midpoint and the printed polymer sheet is exposed to water, the printed sheet dissolves to avoid any disposal problems. An improved method for forming the transparent cleansing bar with a dissolvable, printable film also is disclosed.
