Abstract
A fluid container includes a vessel for holding a fluid, a marker element, and a scale element. The scale element has a scale for indicating a total quantity of the fluid. The marker element and the scale element are adjustable relative to each other to enable an adding up of amounts of fluid and thereby indicate the total quantity of the fluid. The marker element and the scale element are held together by magnetic force and may be detached from each other.
Claims20
A fluid container comprising:
- a vessel capable of holding a fluid, the vessel including a filling scale;
- a marker element;
- and
- a scale element including a total quantity scale corresponding to the filling scale, the total quantity scale including a total fluid quantity indication of a fluid quantity greater than a total volume of the vessel;
- wherein the marker element and the scale element are adjustable relative to each other so that the marker element indicates respective positions on the total quantity scale, the marker element and the scale element being detachably disposed relative to each other by a magnetic force.
