Cardboard container with integrated lid

Abstract

A cardboard container has an integral lid and is obtained from a cardboard sheet duly die-cut in a single piece in which a central sector or bottom is defined, from whose edges two respective isoscelic inverted trapezoidal sectors emerge that determine the larger and smaller side walls of the container. Two of these walls are provided in correspondence to their lateral edges with tabs for gluing together the adjoining walls. From one of the side walls there emerges a sector that acts as a lid, with a configuration in accordance with the configuration of the bottom but with proportionally larger dimensions, which ends in opposition to its fold line in a tab for closing and stabilizing the lid.
