Container system

A container system, comprising:

• an upper container;
• and
• a clip body with a top side attached to a bottom of the upper container and a bottom side configured to attach to a top of a lower container, the clip body including:
• a plurality of outer securing structures formed around a substantially circular outer perimeter of the clip body, each outer securing structure including an outer tab, a ledge formed at a bottom end of the outer tab and extending inward toward a central region of the clip body, and a wing extending upward from the outer tab and outward away from the central region of the clip body in a radial direction, wherein
• each wing is positioned proximate a base of the upper container and configured to contact an inwardly sloping surface around the bottom of the upper container during a coupling operation of the upper container to the clip body;
• each ledge grips an outer lip of a circular rim formed on the top side of the lower container, to thereby collectively releasably grip the lower container;
• and
• the wing is formed on the outer tab opposite a corresponding ledge in an axial direction and is configured to flex when an inward force is applied by a digit of a user to thereby bias the corresponding ledge away from the central region of the clip body and release the lower container.
