    Abstract: A shield, used during industrial material mixing operations for preventing material splatter around the mixing container. They shield is generally formed as a ring that snaps to the top of a conventional bucket. The ring includes an upwardly projecting funnel. The funnel captures materials that have been projected from the bucket during a mixing sequence. The shield is made of a form retaining, bendable or malleable material, such as plastic, or soft metals. This allows for the dried-on materials to be easily and quickly cleaned from the shield. Alternatively, the shield may include a plurality of weak seams provided in uniform intervals along its height for removing a portion of the shield for cleaning or reduction in size when required by a limiting work environment. A pull tab quickly and easily removes the funnel portion at the weak seam.
