A container system, the system comprising:
- a first bowl comprising:
- a first base having a first surface and a second surface opposite and spaced apart from the first surface, and
- a resilient wall, the resilient wall extending at least partially in an axial direction from the first base, wherein an edge of the resilient wall that is spaced apart from the first base defines an opening to the first bowl, and the resilient wall has an inner surface that faces a central longitudinal axis that extends through the first base, wherein the first surface of the first base faces the opening of the first bowl,
- wherein the resilient wall is urgable radially outwardly from the central longitudinal axis of the first bowl from a resting position to an expanded position, and
- wherein the edge of the resilient wall has a resting perimeter length when the resilient wall is in the resting position and an expanded perimeter length when the resilient wall is in the expanded position;
- and
- a second bowl comprising:
- a second base having a first surface and a second surface opposite and spaced apart from the first surface, and
- a rigid wall, the rigid wall extending at least partially in an axial direction from the second base, wherein the rigid wall has a first edge spaced apart from the second base and a second edge opposite and spaced apart from the first edge of the rigid wall, wherein the first edge defines an opening to the second bowl, and the rigid wall has an inner surface that faces a central longitudinal axis that extends through the second base, wherein the first surface of the second base faces the opening of the second bowl,
- wherein the first edge of the rigid wall has a first perimeter length and the second edge of the rigid wall has a second perimeter length,
- wherein the first perimeter length and the second perimeter length of the rigid wall are greater than or equal to the resting perimeter length of the resilient wall and are less than or equal to the expanded perimeter length of the resilient wall,
- wherein at least one groove is defined by, and extends in a circumferential direction along, one of the inner surface of the resilient wall and/or an outer surface of the rigid wall, and at least one protrusion extends in a circumferential direction along the other of the outer surface of the rigid wall and/or the inner surface of the resilient wall,
- wherein the at least one protrusion is engageable within the at least one groove, and
- wherein the first and second bowls are alternatively arrangeable in a first configuration and a second configuration wherein at least a portion of the rigid wall of the second bowl is disposable within at least a portion of the resilient wall of the first bowl wherein, in the first configuration the first surface of the second base faces the first surface of the first base and the bowls define a closed cavity, and in the second configuration, the second surface of the second base faces the first surface of the first base, and
- wherein the portion of the rigid wall abuts the portion of the resilient wall to form a fluid-tight seal when the portion of the rigid wall is disposed within the portion of the resilient wall.
