Packaging containers

Abstract

A packaging container includes a box body and a box lid. The box body includes a bottom wall, a surrounding wall extending upward from the bottom wall and surrounding its periphery, and a flange protruding downward from the bottom wall. The bottom wall and the flange cooperate to define a downward-facing retaining groove. The box lid is detachably fitted onto the box body and includes a lid body, a convex wall surrounding the lid body and cooperating with the lid body to define an upward-facing recessed groove, and a plurality of protrusions located within the recessed groove and protruding upward from the lid body, each in a push-pull manner. When two packaging containers are stacked, the flange of the upper packaging container extends into the recessed groove of the lower packaging container and is located between the convex wall of the lower packaging container and the protrusions, thereby enabling stable stacking.
