lunch box

Abstract

The article relating to the present design (hereinafter referred to as "the Article") is a lunch box comprising a main body formed in the shape of a substantially parallelogram-shaped thin box opening upwards, and having a dividing piece that rises from the bottom surface to divide the bottom into two substantially triangular sections, a substantially triangular-shaped core housed in one of the divided sections of the main body, and a lid that is substantially parallelogram-shaped in plan view, with its peripheral edge fitting to the opening edge to close the opening of the main body. The lid of the Article has a bulge portion in which the corresponding part of the peripheral edge corresponding to one of the acute angles of the peripheral edge bulges outward by a small amount in a substantially arc shape to make it easier to lift upwards when opened.
