Abstract
The present invention relates to foldable cardboard packages, in particular to a single piece cardboard package with adjustable capacity and improved reusability. The object of this invention is a single-piece cardboard package (100) comprising a storage compartment and a lid, wherein the storage compartment includes two squared zones (30), each one delimited at the top by the upper edge of the respective wall panels and at the bottom by a horizontal crease (15), and include diagonal creases (16) that enable the folding of the front two corners of the storage compartment associated with the squared zones (30) to fold the upper edges of the storage compartment, thus decreasing the maximum capacity of the cardboard package. The proposed invention aims to provide a single-piece cardboard package that allows the adjustment of the storage capacity and allows repeated use without compromising the structural integrity and proper sealing of the storage goods.
