A portable receptacle for documents and the like having opposed cover members each being pivotally engaged along confronting sides to an intervening spine. A ring binder is provided on the normally inner face of one cover proximate the spine. Wall-forming members are integral with the other cover member and projecting from the inner face thereof proximate opposed ends and the spine-remote side thereof for abutting the corresponding edge portions of the one cover member when the receptacle is in closed condition whereby the same is of general box-like character. A pair of support members are carried on said other cover member and being pivotally connected to spaced-apart locations on the wall-forming members at the opposite end edges of the other cover member for developing parallel pivot axes extending lengthwise of the support members. Each of said members having a side edge-forming angle of less than 90 DEG with the proximate end of the related support member whereby when said support members are swung into operative position the same will support the receptacle in opened condition at a like angle to a convenient support surface.
