Various implementations include a container system that includes a first and second bowl. The first bowl has a resilient wall that is urgable radially outwardly from a resting position to an expanded position. The edge of the resilient wall spaced apart from a first bowl base has a resting perimeter length and an expanded perimeter length. A rigid wall of the second bowl has a first edge spaced apart from a second bowl base and a second edge opposite the rigid wall first edge each have a perimeter length. The perimeter lengths of the rigid wall are both greater than or equal to the resting perimeter length and are less than or equal to the expanded perimeter length. A groove is defined by the resilient wall and/or rigid wall. A protrusion extends along the other of the rigid wall and/or resilient wall. The protrusion is engageable within the groove.
