Lunchbox structure

Abstract

A lunchbox structure mainly consists of a box body and a lid. The box body has a bottom with a plurality of openings. Between two openings, there is a tear line and two fold lines. After the tear line is torn, the fold lines are raised along the fold lines to form an insertion hole for a partition to be inserted and fixed, thus dividing the bottom of the box into a plurality of spaces. The box body is formed by folding and thermoforming. A side wall extends upward around the bottom of the box, and the top of the side wall forms a box opening. The top edge of the box opening is folded outward to form a lip. The lid has an interlocking groove on its inner side, which is locked in place with the lip. In this way, the lunchbox can be sealed securely using a one-piece molded paper box body, and the space can be customized.
