PROBLEM TO BE SOLVED: To provide a sponge scrub brush that enables cleanly washing to the bottom of a deep container where hand-fingers cannot reach there for solving a problem in which conventionally a scrub brush with a long handle is often used in order to cleanly wash to the bottom in the deep container; therefore, it takes time and labor for changing the scrub brush.;SOLUTION: A sponge scrub brush of the present invention provide an effect of cleanly washing to a bottom and its periphery by providing a core material 2 having moderate hardness in the inside of a sponge scrub brush body 1 and transmitting the force of hand-fingers 4 to the tip of the sponge scrub brush. Thus, the core material is contained in the inside of the sponge scrub brush, the core material is held by the hand-fingers, and the force of the hand-fingers is transmitted to the scrub brush tip, and thereby the problem is solved. Accordingly, the outside and depth of the container can be washed to the deep bottom without changing the scrub brush in the washing work.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
