发明名称 Level case with positioning indentations
摘要 A level case includes a tubular body having a series of walls that define an internal cavity, and a cap that selectively closes the internal cavity. A series of indentations are formed in the walls, and are configured to receive and engage the corners of a level received within the internal cavity. The internal cavity defines spaces between the level surfaces and the facing surfaces of the walls, to protect the level surfaces in the event the walls of the tubular body are subjected to forces that cause inward deformation of the walls. The cap is configured similarly to the tubular body, including indentations that receive the corners of the level. The cap is engaged over the opening of the tubular body so as to enclose a portion of the level that extends outwardly of the tubular body. The indentations in the tubular body are continuous throughout a majority of the length of the tubular body.
