The Tubbi Knockbox is the perfect accessory for the home barista to help dispose of espresso pucks. The box is made of ABS plastic and is extremely tough. The food safe rubber bar absorbs the energy from the portafilter to minimize noise and is reinforced with stainless steel.
There is a silicone gasket that is press-fitted into a groove in the base. This ring-shaped gasket helps prevent the Tubbi from moving and also helps to reduce the noise. The gasket will come out if you pull it hard enough, but under normal use it will not fall out.
The knockbox may be small but it can comfortably hold 10 double pucks of coffee before it needs emptying. To empty, just lift the rubber bar out and discard the coffee. The plastic tub is dishwasher safe but a simple rinse with a little detergent works every time.
