Enclosure with a detachable lid

摘要

An enclosure for eg a mixer has a body 21 and a detachable lid 22. Each side wall 24 of the body carries a lug 36 in the form of a cylindrical protrusion with flattened sides and a terminal button 37. Each side wall 28 of the lid has a corresponding lug-receiving aperture 40 with a narrow access opening 41 so shaped so that the lid can be detached from the lug only when the narrow opening and the flattened sides of the lug are aligned.
