  • Patent number: 4453909
    Abstract: Apparatus for making a tablet of soap containing a perfume-containing core, hollow or solid, fabricated from a hard plastic material, either thermosetting or thermoplastic. Soap from the resulting composite tablet is usable until the core is washed clean and is aromatized until the core is washed clean. This obviates the wastage of soap which normally occurs as a conventional soap tablet becomes very thin on use and, at the same time, gives rise to a continuously aromatized soap tablet.
