1. An apparatus, comprising:
a container body defining an internal cavity, a first outer diameter, and a second outer diameter, the container body comprising:
a first side wall surrounding the internal cavity, the first side wall defining the second outer diameter of the container body, which second outer diameter is a maximum outer diameter of the first side wall, the first side wall further defining axially-opposing first and second end portions;
a neck connected to, and extending from, the first side wall at the first end portion, the neck defining the first outer diameter of the container body; and
a bottom wall connected to, and extending from, the first side wall at the second end portion, opposite the neck;
and
a container lid attached to, and sealingly engaged with, the neck of the container body, the container lid comprising:
a second side wall;
a top wall connected to the second side wall;
wherein the second side wall and the top wall, in combination, define an internal region of the container lid;
wherein the container lid further comprises:
an internal ridge extending inwardly and into the internal region, the internal ridge engaging an outside surface of the neck; and
an internal collar extending from the top wall and into the internal region, the internal collar engaging an inside surface of the neck;
wherein the top wall comprises a central portion and an outer edge portion connecting the central portion to the second side wall;
wherein the outer edge portion comprises a radially-inwardly-facing external surface adjoining the central portion;
wherein the radially-inwardly-facing external surface and the central portion, in combination, define an external concavity of the container lid, opposite the internal region;
wherein the container lid is detachable from, and re-attachable to, the neck of the container body;
wherein at least part of the second end portion of the first side wall adjoins at least part of the bottom wall so that, in combination, the adjoining parts of the first side wall and the bottom wall define a first contiguous three-dimensional profile of the container body;
wherein at least part of the radially-inwardly-facing external surface adjoins at least part of the central portion so that, in combination, the adjoining parts of the radially-inwardly-facing external surface and the central portion define a second contiguous three-dimensional profile of the container lid;
wherein, when the container lid is detached from the neck of the container body, the second contiguous three-dimensional profile of the container lid is adapted to matingly receive the first contiguous three-dimensional profile of the container body so that:
the bottom wall of the container body engages the central portion of the top wall of the container lid; and
the second end portion of the first side wall of the container body engages the radially-inwardly-facing external surface of the top wall of the container lid;
wherein the first side wall of the container body is frustospherical or frustospheroidal; and
wherein a ratio of the first outer diameter to the second outer diameter is greater than or equal to 2:3.
