Abstract:
1. A container comprising: a bottom portion; a side portion extending from the bottom portion, in which the side portion comprises an interior wall and an exterior wall, wherein the container directly contains a fluid adjacent the interior wall, and wherein the side portion provides a constant cross-sectional area along its entire length; and a balance mass, in which the balance mass comprises a core portion encapsulated by an encapsulant, and wherein the encapsulant is in pressing engagement with the exterior wall, and further wherein the encapsulant directly contacting the core portion forms a base region in contacting adjacency with a container support surface, and in which the encapsulant further comprises a side surface and a tip lip portion extending radially from the side surface at a proximal end, the tip lip offset from the container support surface and providing a ridge interposed mid-way between the proximal end and a distal end of the tip lip, wherein the tip lip portion mitigates an inadvertent engagement of the side portion with the container support surface supporting the base region.
