Abstract:
A device with weighing capability (or “scale feature”) and also anvil capability (or “tapping feature”) allows accurate and precise filling of an espresso portafilter with coffee grounds for use in beverage preparation. Some versions switch between a protected mode for anvil use, and a weighing mode for accurate weighing of the portafilter and its grounds, by pivoting the entire load cell into and out of a protected location wherein tapping/shocks do not flex/strain the load cell free end. In other versions, one or more stop(s)/limit(s) are near the load cell free end or associated elements, and the free end/elements move during said tapping/shocks but only to the stop(s)/limit(s), corresponding to a safe amount of strain for the load cell. Also, this way, weighing the portafilter and its contents may continue between taps without switching to a separate protected mode.
