Wash ball
First Claim
1. A wash ball structure comprising an upper case half and a lower case half and wherein the upper case half is a hollow semi-spherical shell with a plurality of holes on the surface thereof, has external screw threads around the connecting end and is provided with a plurality of cavities scattered on the end surface of the connecting end;
- andthe lower case half is also a hollow semi-spherical shell with a plurality of holes on the surface and has an annular flange around the connecting end;
said annular flange being larger than the semi-spherical shell in diameter and having internal screw threads formed on the inner wall surface and a plurality embossed round dots dispersed on the connecting end surface;
said upper case half and said lower case half being coupled with each other by means of an engagement between the external and the internal screw threads and an engagement between the embossed round dots and the recessed cavities to form a wash ball that can avoid looseness due to water wash.

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.
