Abstract:
A cylindrical case, comprising:an outer shell, comprising outer side walls joined by an outer edge wall around a perimeter of said case, and an outer open face extending along an S-shaped line defined by said outer side walls, said outer shell comprising a segment of said cylindrical case, an said outer open face being spaced from said outer edge wall adjacent to one end of said S-shaped line;an inner shell, comprising inner side walls joined by an inner edge wall around a perimeter of said case, and an inner open face extending along an S-shaped line defined by said inner side walls, said inner shell comprising a segment of said cylindrical case complementary to said outer shell;wherein said inner shell is coupled to said outer shell for relative rotation about an axis of rotation, said axis located substantially at a center of said case when said inner shell is in a closed position, whereby said inner shell is rotatable between an open position in which said inner shell nests inside said outer shell with said inner open face substantially aligned with said outer open face, thereby providing access to an interior of said case, and said closed position in which said inner shell and said outer shell cooperate to enclose a cylindrical compartment.
