Foldable storage box

Abstract

The present invention includes a hollow box body, a top cover and a bottom cover which are removably fastened with a top end and a bottom end of the box body respectively, and the box body is a plastic box body which is foldable and integrally formed by injection molding. The plastic box body has front and rear hard plastic walls which are symmetrical, and left and right hard plastic walls which are symmetrical; foldable soft plastic curved walls are disposed at intersections between the front, rear, left and right hard plastic walls. The storage box saves occupying space, and is susceptible to low production costs and has a simple structure. When in use, it is good in strength and securely fastened.
