The strip is transparent and includes opaque markings which are viewable through the two rings of the transparent strip to define a predetermined pattern, representing a correct solution of the puzzle, only when the two Moebius rings are located in a predetermined juxtaposition with respect to each other.

摘要： A non-spillable portable cigarette ashtray has an ash receptacle open at its top, and a holder also having an open top and a flat bottom supporting the ashtray in an upright position. The ashtray is pivotally mounted to the holder and includes a weight which is effective, should the holder inadvertently be moved to a non-upright position, to cause the ash receptacle to pivot and to remain in an upright position, thereby preventing spilling out of the contents of the ash receptacle.
