  • Patent number: 6032495
    Abstract: A wash ball comprises an upper and an lower case half both of which have a semi-spherical shell body with openings formed thereon. The connecting end of the upper case half is provided on the end surface with a plurality of cavities and on the peripheral surface with outer screw threads. The lower case half is also provided with openings on the shell body and a plurality of embossed round dots on the end surface and an annular flange around the connecting end. The annular flange has internal screw threads formed on the inner wall surface. With such an arrangement, the upper and the lower case half can be put together to enclose solid detergent therein by means of the engagement of screw threads. When the upper case half links with the lower case half to form a wash ball, each embossed round dot extends into a cavity to prevent the ball from loosened in water. The wash ball has the advantages of simplified structure and assembling processes.

  • Patent number: 6013610
    Abstract: A solid state bath agent containing Na2CO3 (Sodium Carbonate), NaHCO3 (Sodium Bicarbonate), Na2SO4 (Sodium Sulfate), Citric acid, CMC (Carboxymethyl Cellulose), Bactericide, Silicone oil, Vitamin E, Vitamin C, AHA and fragrance. Na2CO3, NaHCO3, Na2SO4 and Citric acid are dried by hot air, then mixed with the other materials and then pressed into individual bath cakes (bath balls), and then the finished individual bath cakes (bath balls) are well packed in an air-tight sealing container.

  • Patent number: 5658870
    Abstract: A composition of super molecule active solid cleaning agent manufactured from super molecules and inorganic chemicals consisting of suitable amounts in weight percent of an anionic surface active agent, a sodium carbonate, a sodium silicate, a fluorescent whitening agent, a carboxymethyl cellulose, a non-ionic surface active agent, a di-sodium edetate, an oleic acid and an essence. Water molecules can be activated by the active solid particles as they are immersed in the water. The active solid particles may rub with each other to generate excessive amount of negative hydroxyl ions (OH) in water. Accordingly, the pH value in water increases and the water molecules are activated. As a result, the activated molecules of water may readily penetrate into the tissue of the fabric to weaken and soften the connection between the dirt and tissue of the fabric. The dirt attached to fabric can be readily removed.
