Abstract: Embodiments herein describe a separable, multi-sectioned reusable liquid drinking bottle that can be disassembled for cleaning. The drinking bottle has detachable upper and lower sections and a bottle top. The upper and lower sections are engageable and separable from one another. Both the upper and lower portions of the drinking bottle may be separately encased in a vacuum-sealed insulating layer of insulating material. The bottle portions are designed to engage each other in a leak-proof fashion to create a liquid containment vessel. The upper and lower portions of the drinking bottle create a containment vessel made of stainless steel, such that any liquids placed in the bottle only come in contact with this material that comprises the liquid containment vessel.
