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.
