The idea: developing an absolutely clean, no-spill coffee grinder. The new BISTRO electric grinder uses a borosilicate glass container to catch the ground coffee as glass is inherently static-free. The increased production tolerance of borosilicate glass is countered by the creative combination of silicone and nylon for the lid. The soft lid is constantly under slight pressure to fill any eventual irregularities of the glass and springs back to its shape and size when removed. This makes for a tight, snug lid and no spilled coffee powder. The borosilicate glass container comes with a silicone band to make it slip-proof.
