Combined lid structure and packaging structure

Abstract

This disclosure provides a combined cover structure comprising a base plate and at least one buffer plate. The at least one buffer plate is integrally connected to one side of the base plate in a bendable manner. A fold line exists between the base plate and the at least one buffer plate. The at least one buffer plate can be bent or unfolded relative to the base plate along the fold line. This reduces material usage and increases protective strength.
