An Espresso Knock Box is a device used to store spent espresso grounds.
      It is generally made out of stainless steel or plastic, since they are subjected to repetitive knocking and tapping to dislodge espresso after use. In various coffee houses Espresso Knock Boxes are seen as stainless steel boxes usually located near the coffee grinders or the espresso machines, or as drawers which are integral within the bar structure.
