A receptacle for containing fluids constructed of a single wall wherein the foci of the well is offset from the foci of the perimeter, such that the resulting wall is of purposely differential thickness, to a point of maximal width. This may be of unitary construction from commonly used materials, utilizing the inherent insulating properties of the material selected, lowering manufacturing complexity and cost. In an application as a thermal container for beverages, the thickest aspect of the receptacle provides thermal insulation without interior or exterior insulating materials or internal air or vacuum chambers, and shifts the balance or center of gravity toward the holder, allowing more ease of lift. The specially shaped handle of the preferred embodiment, the present invention further enhances comfort and safety by reducing the potential for hand-burning, providing an ergonomic lifting grip which is beneficial to individuals with hand or wrist impairments.
