Foldable storage box

Abstract

Disclosed in embodiments of the present application is a foldable storage box including a plurality of box body components and several first zippers. Each of the box body components includes several side walls and a flexible sub-bottom wall. A user can join a pair of vertical edges and a pair of bottom edges of box body components by sliding a slider of the first zipper to close the first zipper, so that the foldable storage box is brought into a joined state, that is, forming a storage chamber. In general, a bottom wall of the foldable storage box of the present application is easier to store and less likely to form a swollen structure. The folded form of the foldable storage box of the present application then has a more organized form and a smaller thickness, which is convenient for storage and transportation.
