Multi-compartment paper lunch boxes and paperboard with reinforced structure

Abstract

A multi-compartment paper lunch box and paperboard with a reinforced structure are disclosed. The multi-compartment paper lunch box includes a bottom wall unit, a surrounding wall unit, a first partition unit, and a reinforcing unit. The surrounding wall unit extends upward from the outer periphery of the bottom wall unit and includes two first side portions, two second side portions, and a plurality of ends connecting adjacent first side portions and second side portions. Each second side portion has two overlapping areas. These overlapping areas overlap the outer sides of adjacent ends and first side portions. The first partition unit divides a chamber into a first holding space and a second holding space. In this way, liquid in the chamber is blocked by the ends, preventing liquid from seeping out of the chamber from the interface between the first side portion and the adjacent second side portion, thus achieving the effect of preventing liquid leakage.
