Children's toy box

Abstract

Some embodiments of the present disclosure relate to a children's toy box. The toy box may include a support pad, a bottom, and a barricade portion. The barricade portion may include four lateral walls, where any two adjacent walls can be connected to one another. The bottom may include a first and second bottom. The children's toy box can be folded with the support pad being moved to the inside of the box. The box can be folded afterwards, where the lateral walls connected to the bottom portion are also folded. In this manner, the children's toy box can be reduced to a substantially flat structure when not in use. When the need arises, the children's toy box can be returned to a boxed structure to effectively solve the problem of oversized children's toy boxes.
