Packaging boxes

Abstract

This product is a standard packaging box that can be used for transport and storage when the top is sealed, but it has a structure that allows it to be held in a partially open state when the top flaps are engaged with each other during assembly, making it easy to check, store, and retrieve the contents. As shown in the "Reference Diagram Showing Assembly Method," first, fold the triangular cutout portion of the long side flap inward, then fold the short side flap inward along the scribed line to form a roughly triangular shape. Then, by tilting each flap inward and engaging the roughly triangular shape of the short side flap with the cutout portion of the long side flap, the top shape can be maintained.
