Container with nestable structure
In one or more embodiments, the exemplary containers described herein include a corner structure that can facilitate stacking while limiting reliance on satellite rings. For example, in certain embodiments, a container includes a step-like corner structure with a series of stackable portions. Thus, in these embodiments, more containers can be stacked together in a smaller space, such that shipping and manufacturing processes are more efficient and less costly than with traditional containers.
