Stackable storage system, mating interface and storage container

A stackable storage system, a mating interface, and a storage container. The stackable storage system includes a first container, a second container, and a latch movable between a first position and a second position. The first container includes a protrusion extending away from the first container in the stacking direction. The edge portion extends from the protrusion along a plane substantially perpendicular to the stacking direction. The second container includes a recess. The recess receives the protrusion when the first container and the second container are stacked on each other in the stacking direction. When in the first position, the latch overlaps the edge portion with respect to the stacking direction to secure the first container and the second container. When the latch is in the second position, the latch and the edge portion are positioned to each other in a non-overlapping manner to allow the first container to be separated from the second container. 一种可堆叠存储系统，一种配合接口，以及一种存储容器。该可堆叠存储系统包括第一容器、第二容
